    Liver scintigraphy was performed in 12 cases with fulminant hepatitis, in 8 cases with severe acute hepatitis and in 44 cases with acute hepatitis. Scintiphotoes of severe hepatitis showed reduction of liver size, marked visualization of the bone marrow and the spleen, so this pattern was useful to differentiate from acute hepatitis. Relative size of the liver calculated by A.L.I. (anterior liver index) showed significant reduction in severe hepatitis compared with that of acute hepatitis. Three of five patients with died of severe hepatitis showed high uptake in the lung and ribs, but none of fifteen patients with severe hepatitis who recovered showed the abnormal accumulation in the lung and in the ribs.

    Objective: To assess and compare the severity of depression in chronic hepatitis B (CHB), chronic hepatitis C (CHC) and healthy subjects. Study Design: Comparative study. Place and Duration of Study: Shifa International Hospital, Islamabad from July 2011 to February 2012. Methodology:A total of 206 subjects were divided in three groups. Group-I (chronic hepatitis C, n = 95), group-II (chronic hepatitis B, n = 29) and group-III (healthy subjects, n = 82). They were matched for age, gender and socioeconomic status and were compared for frequency and severity of depression as measured by Hospital Anxiety and Depression Scale (HADS). Results: Some degree of depression was noted in all groups. Frequency of depression was 72.6% in group-I, 58.6% in group-II and 37.8% in group-III (p value < 0.001). Conclusion: Both CHC and CHB had high frequency of some degree of depression. Hepatitis C patients had more depressive features than CHB. It is worthwhile to do more close mental health observation in them. A multidisciplinary team including a psychiatric specialist can help in this approach. (author)

    A correlation between hepatitis A virus (HAV) genomes and the clinical severity of hepatitis A has not been established. The viral load in sera of hepatitis A patients was examined to determine the possible association between hepatitis A severity and HAV replication. One hundred sixty-four serum samples from 91 Japanese patients with sporadic hepatitis A, comprising 11 patients with fulminant hepatitis, 10 with severe acute hepatitis, and 70 with self-limited acute hepatitis, were tested for HAV RNA. The sera included 83 serial samples from 20 patients. Viral load was measured by real-time RT-PCR. The detection rates of HAV RNA from fulminant, severe acute, and acute hepatitis were 10/11 (91%), 10/10 (100%), and 55/70 (79%), respectively. Mean values of HAV RNA at admission were 3.48 ± 1.30 logcopies/ml in fulminant, 4.19 ± 1.03 in severe acute, and 2.65 ± 1.64 in acute hepatitis. Patients with severe infection such as fulminant hepatitis and severe acute hepatitis had higher initial viral load than patients with less severe infection (P hepatitis after clinical onset (P = 0.19). HAV RNA was detectable quantitatively in the majority of the sera of hepatitis A cases during the early convalescent phase by real-time PCR. Higher initial viral replication was found in severely infected patients. An excessive host immune response might follow, reducing the viral load rapidly as a result of the destruction of large numbers of HAV-infected hepatocytes, and in turn severe disease might be induced. 2010 Wiley-Liss, Inc.

    Mildly elevated transaminases are often observed in anorexia nervosa patients, but severe hepatitis is less common. We suggest that hypoperfusion is the pathogenetic factor that causes severe hepatitis in a patient with a very poor nutritional status and present an overview of previous case reports. In our patient, early initiation of intravenous fluids resulted in rapid recovery of the liver test abnormalities, despite minimal oral caloric intake, the refusal of enteral feeding and the development of a hypoglycemic coma. Two months after admission, transaminases had normalized. Reversible severe hepatitis has been described in most of the cases, with only one anorexia nervosa-related fatal hepatitis. In general, both adequate hydration and gradual enteral feeding with monitoring of electrolytes are essential in the management of anorexia patients with severe hepatitis.

    Hepatitis-C viral infection is a global health problem. It has been estimated that approximately 170 million individuals are infected with hepatitis-C virus. Hepatic steatosis is a frequent histological feature in patients with chronic hepatitis-C infection. Histological examinations show that up to 50% of these patients have variable degrees of hepatic steatosis, even in the absence of other possible steatogenic factors like alcohol, drugs or metabolic syndromes. The objective of this study was to determine the frequency and severity of steatosis in patients with Chronic Hepatitis-C. Methods: This cross sectional study was carried out from 1st January 2010 to 1st July 2010 at the department of Gastroenterology PIMS, Islamabad. A total of 127 patients of chronic hepatitis-C were enrolled in the study after taking informed written consent. Frequency and severity (mild, moderate and severe) of steatosis was assessed on the basis of liver biopsy. Results: A total of 127 patients were included in the study. Mean age of the patients was 36.24 years. Out of 127 patients, 48(38%) were male and 79(62%) were female. Steatosis was present in 50(39%) patients with chronic hepatitis-C infection. whereas steatosis was absent in 77(61%) patients. Conclusion: The presence of steatosis on liver biopsy in patients with chronic hepatitis-C is common (39% patients) and female patients had slightly more severe degree of steatosis as compared to male patients.

    Objective: To evaluate the correlation between ammonia levels with the severity of HE in patients coming to the tertiary care hospital with liver cirrhosis and hepatic encephalopathy (HE). Study Design: Descriptive, analytical study. Place and Duration of Study: Shifa International Hospital, Islamabad, from January 2011 to February 2012. Methodology: A total of 135 patients with liver cirrhosis and HE had serum ammonia levels measured on admission. The diagnosis of HE was based on clinical criteria, and its severity was graded according to the West Haven Criteria for grading of mental status. Ammonia levels were correlated with the severity of HE using Spearman rank correlation. Results: Out of 20 patients with normal ammonia levels, 13 (65%) were in HE I-II, 6 (30%) were in grade-III, while 1 (5%) patient was in grade-IV HE. Out of 45 patients with mild hyperammonemia, 27 (60%) were in grade I-II, 12 (26%) were in grade-III and 6 (13%) were in grade-IV HE. Out of 34 patients with moderate hyperammonemia, 9 (26%) were in grade I-II, 18 (53%) were in grade-III, and 7 (20%) were in grade-IV HE. Out of 36 patients with severe hyperammonemia, 31 (86%) patients were in grade-IV HE (p < 0.001). Conclusion: Ammonia levels correlated with the severity of hepatic encephalopathy. Greater the ammonia level, severe is the grade of hepatic encephalopathy. (author)

    Hepatitis E virus (HEV) is endemic in Asian and African countries but is rarely reported in Western countries. Although there are some prominent neurological manifestations, HEV is rarely recognized by neurologists. This is a case report of myositis induced by HEV. We report the life-threatening case of a 57-year-old man with flaccid tetraparesis due to myositis, acute hepatitis, and renal failure caused by HEV infection. Muscle biopsy revealed scattered myofiber necrosis with a diffuse, mild lymphomonocytic infiltrate in the endomysium and perimysium. Because the patient suffered from an acute HEV infection with a rapidly progressive course of severe myopathy, we started ribavirin treatment. He recovered partially within 3 weeks and recovered fully within 6 months. This case highlights a neurological manifestation of endemic HEV infection with severe myositis in a patient with alcoholic chronic liver disease. Ribavirin treatment is effective in severe HEV infection and may also lead to rapid neurological recovery. © 2015 Wiley Periodicals, Inc.

    Full Text Available Rodolfo SaccoDepartment of Gastroenterology, Pisa University Hospital, Pisa, ItalyAbstract: Despite the effective management of most cases of hepatitis B virus (HBV infection, there is still much room for improvement in the treatment of more severe cases of hepatitis B, such as those occurring in patients with decompensated cirrhosis, in transplanted subjects, and in patients with exacerbations of HBV infection. Among the treatments currently approved for the therapy of hepatitis B, entecavir determines a rapid suppression of viral load. This drug is also associated with a high genetic barrier and an overall favorable safety profile. This review provides an overview of recent evidence related to the use of entecavir in the management of the most severe forms of hepatitis B. The results obtained for this drug in real-life clinical practice are also reviewed.Keywords: entecavir, HBV, hepatitis B, chronic hepatitis

    Radiation-induced liver disease (RILD), often called radiation hepatitis, is a syndrome characterized by the development of anicteric ascites approximately 2 weeks to 4 months after hepatic irradiation. There has been a renewed interest in hepatic irradiation because of two significant advances in cancer treatment: three dimensional radiation therapy treatment planning and bone marrow transplantation using total body irradiation. RILD resulting from liver radiation can usually be distinguished clinically from that resulting from the preparative regime associated with bone marrow transplantation. However, both syndromes demonstrate the same pathological lesion: veno-occlusive disease. Recent evidence suggests that elevated transforming growth factor β levels may play a role in the development of veno-occlusive disease. Three dimensional treatment planning offers the potential to determine the radiation dose and volume dependence of RILD, permitting the safe delivery of high doses of radiation to parts of the liver. The chief therapy for RILD is diuretics, although some advocate steroids for severe cases. The characteristics of RILD permit the development of a grading system modeled after the NCI Acute Common Toxicity Criteria, which incorporates standard criteria of hepatic dysfunction

    Severe alcoholic hepatitis is still associated with high mortality and presence of liver failure manifested by jaundice, coagulopathy and encephalopathy is a poor prognostic indicator. The management of these patients includes at first hand several supportive measures as treatment of alcohol withdrawal, administration of fluid and vitamins and admission to an intensive care unit in the unstable patient. Glucocorticoids have been since decades the most intensively studied therapy in alcoholic hepatitis and are effective in certain subgroups. Indication for such a therapy is usually defined on a Maddrey Discriminant Function > 32. The Lille score at day 7 is used to decide whether corticosteroid therapy should be stopped or continued for a 1 month course. Nutritional supplementation is also likely to be beneficial. The main progress in better understanding its pathophysiology has come from cytokine studies. Various proinflammatory cytokines such as tumor necrosis factor-alpha (TNFα) or interleukin-1 (IL-1) have been proposed to play a role in this disease. This advancement has recently led to pilot studies investigating anti-TNF drugs such as pentoxifylline, infliximab (anti-TNF antibody) or etanercept in the treatment of this disease. These studies revealed besides for pentoxifylline rather negative results. Despite this fact, targeting of certain cytokines such as IL-1 remains an attractive treatment concept for this devastating disorder in the future.

    Full Text Available Chronic hepatitis B virus (HBV infection is a major global health problem with an estimated 400 million HBV carriers worldwide. In the natural history of chronic hepatitis B (CHB, spontaneous acute exacerbation (AE is not uncommon, with a cumulative incidence of 10%–30% every year. While exacerbations can be mild, some patients may develop hepatic decompensation and even die. The underlying pathogenesis is possibly related to the activation of cytotoxic T lymphocyte-mediated immune response against HBV. An upsurge of serum HBV DNA usually precedes the rise of alanine aminotransferase (ALT and bilirubin. Whether antiviral treatment can benefit CHB with severe AE remains controversial, but early nucleos(tide analogues treatment seemed to be associated with an improved outcome. There has been no randomized study that compared the effects of different nucleos(tide analogues (NA in the setting of CHB with severe AE. However, potent NAs with good resistance profiles are recommended. In this review, we summarized current knowledge regarding the natural history, pathogenetic mechanisms, and therapeutic options of CHB with severe AE.

    Background and Aims Clinical manifestations of hepatitis A virus (HAV) infection vary from mild to fulminant hepatic failure (FHF) in adults. We investigated the relationship between laboratory findings, including viral load, and clinical outcomes in patients with acute hepatitis A (AHA) and evaluated predictive factors for severe acute hepatitis (s-AH). Methods We analyzed the clinical manifestations of AHA in 770 patients. Patients with a prothrombin time (PT) of less than 40% of normal were classified as s-AH and included 4 patients with FHF, 11 patients with acute renal failure, and 3 patients with prolonged jaundice (n = 128). Other patients were defined as mild acute hepatitis (m-AH) (n = 642). Serum samples were obtained from 48 patients with acute hepatitis A. Among them, 20 with s-AH, and 28 with m-AH, were tested for HAV RNA titer. Results In a multivariate analysis, age (HR = 1.042, P = 0.041), peak creatinine (HR = 4.014, P = 0.001), bilirubin (HR = 1.153, P = 0.003), alanine aminotransferase (ALT) (HR = 1.001, Phepatitis A.

    Objective: Because of the limited of 99 Tc m -diethyl iminodiacetic acid ( 99 Tc m -EHIDA) hepatobiliary scintigraphy in the diagnosis of severe cholestatic infant hepatitis syndrome, trial use 99 Tc m -methoxy isobutyl isonitrile ( 99 Tc m -MIBI) as a new hepatobiliary scintigraphy imaging agent to understand its applied basis and primary evaluate value in diagnosis of severe cholestatic infant hepatitis syndrome. Methods: constructed choledochal atresia animal model and investigated the application basis of 99 Tc m -MIBI hepatobiliary scintigraphy. Twenty-seven children patients of severe cholestatic who finally confirmed infant hepatitis syndrome were underwent firstly 99 Tc m -EHIDIA hepatobiliary scintigraphy. After 24 h delay imaging next day, 99 Tc m -MIBI hepatobiliary scintigraphy was underwent after 1 h. Two imaging agents of value in the diagnosis of severe cholestatic infant hepatitis syndrome were compared. Results: It was proved that 99 Tc m -MIBI was surely excreted by hepatobiliary and had no intestinal autocrine phenomenon in animal test. So 99 Tc m -MIBI can be used to undergo hepatobiliary scintigraphy. The sensitivity of 99 Tc m -MIBI hepatobiliary scintigraphy in the diagnosis of severe cholestatic infant hepatitis syndrome was 100% in our primary clinical study. Its sensitivity was higher than which of 99 Tc m -EHIDA hepatobiliary scintigraphy (66.67%) by far. Conclusion: With regard to those children patients who suspected highly severe cholestatic infant hepatitis syndrome in clinical, the sensitivity of 99 Tc m -MIBI hepatobiliary scintigraphy is obviously superior to conventional 99 Tc m -EHIDA hepatobiliary scintigraphy.

    A study was conducted to estimate the functional reserve of the liver of patients with severe hepatitis by computed tomography (CT), in particular employing the integrated CT number of the whole liver (ICTN). ICTN was calculated by integrating the product of 'area' times 'mean CT number' of the liver in each CT slice for the entire height of the liver. The following results were obtained: 1) In patients with fulminant hepatitis (FH) as well as those with subacute hepatitis (SAH), ICTN was found to be significantly lower as compared to that of patients with acute hepatitis (AH) or non-hepatic diseases. In addition, in FH and SAH patients, ICTN showed a larger degree of decrease when compared with such conventional parameters as either estimated liver volume or mean hepatic CT number. Thus, ICTN seems to more sensitively reflect the changes in functional reserve of the liver. 2) ICTN showed significant positive correlations with prothrombin time and plasma BCAA/AAA ratio, and a significant negative correlation with plasma methionine level. 3) Time course of changes in ICTN correlated well with the clinical features of severe hepatitis. In particular, patients with initial ICTN values above 20 l·HU/m 2 of body surface area showed significantly higher survival rate than those with initial ICTN below 20. In conclusion, ICTN well indicates the functional reserve of the liver, and is further suggested to be valuable as a parameter to predict the prognosis of patients with severe hepatitis. (author)

    Liver transplantation has been reported in the literature as an extreme intervention in cases of severe and complicated hepatic trauma. The main indications for liver transplant in such cases were uncontrollable bleeding and postoperative hepatic insufficiency. We here describe four cases of orthotopic liver transplantation after penetrating or blunt liver trauma. The indications were liver failure, extended liver necrosis, liver gangrene and multiple episodes of gastrointestinal bleeding related to portal hypertension, respectively. One patient died due to postoperative cerebral edema. The other three patients recovered well and remain on immunosuppression. Liver transplantation should be considered as a saving procedure in severe hepatic trauma, when all other treatment modalities fail.

    Full Text Available Endothelin receptor antagonists are commonly used in the treatment of pulmonary hypertension. Sitaxsentan, a selective endothelin A receptor blocker, induces a mild transaminitis in approximately 3% to 5% of patients, but rarely an acute severe hepatitis. A case involving a 61-year-old female with sitaxsentan-induced acute severe liver failure is presented. Depite withdrawal of therapy, her liver tests failed to improve. After six weeks of monitoring, the patient was administered high-dose corticosteroids, with a good clinical and biochemical response. While endothelin receptor antagonists are postulated to cause hepatitis by inhibition of a bile salt transporter pump, an immune-mediated or idiosyncratic mechanism should be considered.

    The accuracy of ultrasonography in detection of feline hepatic lipidosis was studied retrospectively. The following ultrasonographic criteria were associated positively with severe hepatic lipidosis: the liver hyperechoic, compared with falciform fat; the liver isoechoic or hyperechoic, compared with omental fat; poor visualization of intrahepatic vessel borders; and increased attenuation of sound by the liver. In a group of 36 cats with clinically apparent hepatobiliary disease and in which liver biopsy was done, liver hyperechoic, compared with falciform fat, was the best criterion for diagnosis of severe hepatic lipidosis with 91% sensitivity, 100% specificity, and 100% positive predictive value.

    Sevoflurane is thought to have a potential for hepatotoxicity. A few cases of hepatotoxicity have been reported since it was introduced in 1999 into clinical practice in Japan. The underlying pathophysiology of hepatotoxicity is non-specific. We report a case of severe hepatic dysfunction after uneventful sevoflurane anesthesia in a child with posterior fossa resection of medulloblastoma. The case of sevoflurane being incriminated is unclear due to various confounding factors that is worthy of discussion. (author)

    Severe acute hepatotoxicity is a well known complication following the ingestion of ecstasy (3,4-methylenedioxymethamphetamine [MDMA] ecstasy). Hepatic dysfunction has also been reported after acute cocaine intoxication. However, chronic hepatitis after prolonged use of ecstasy and/or cocaine has rarely been reported. We report the case of a 27-year-old woman hospitalized with edema, ascites and severe liver failure (prothrombin rate 33%), following the use of ecstasy and cocaine over the previous 9 months. Clinical, biological, radiological and pathology findings were recorded at admission and over 8 years' follow-up. Liver biopsy showed architectural distortion caused by bridging fibrosis, proliferation of cholangioles, and lesions of active interface hepatitis. Other causes of acute and chronic liver disease were excluded. Magnetic resonance imaging showed marked liver fibrosis. After withdrawal of both substances clinical examination and liver function tests progressively normalized. Long-term monitoring with magnetic resonance imaging showed progressive regression of fibrosis. Use of ecstasy and cocaine may cause chronic hepatitis leading to marked liver fibrosis, which may regress after withdrawal of both substances. Copyright © 2013 Elsevier Masson SAS.

    In this study, we compared hepatic ultrastructure in healthy cats, in cats with severe hepatic lipidosis, and in cats with experimentally induced, chronic, extrahepatic bile duct occlusion. Ultrastructural features unique to the lipidosis syndrome included an apparent reduction in number of peroxisomes and alteration in their morphologic features. The quantity of endoplasmic reticulum, Golgi complexes, and lysosomes was subjectively reduced, and paucity of cytosolic glycogen was observed. Bile canaliculi appeared collapsed because of cytosolic distention with lipid. Mitochondria were reduced in number and were markedly pleomorphic. Cristae assumed a variety of shapes, lengths, and orientations. Ultrastructural features of bile duct occlusion were similar to those described in other species and differed from those in cats with hepatic lipidosis.

    To compares the clinical features of patients infected with hepatitis E virus (HEV) with or without severe jaundice. In addition, the risk factors for HEV infection with severe jaundice were investigated. We enrolled 235 patients with HEV into a cross-sectional study using multi-stage sampling to select the study group. Patients with possible acute hepatitis E showing elevated liver enzyme levels were screened for HEV infection using serologic and molecular tools.HEV infection was documented by HEV antibodies and by the detection of HEV-RNA in serum. We used χ(2) analysis, Fisher's exact test, and Student's t test where appropriate in this study. Significant predictors in the univariate analysis were then included in a forward, stepwise multiple logistic regression model. No significant differences in symptoms, alanine aminotransferase, aspartate aminotransferase, alkaline phosphatase, or hepatitis B virus surface antigen between the two groups were observed. HEV infected patients with severe jaundice had significantly lower peak serum levels of γ-glutamyl-transpeptidase (GGT) (median: 170.31 U/L vs 237.96 U/L, P = 0.007), significantly lower ALB levels (33.84 g/L vs 36.89 g/L, P = 0.000), significantly lower acetylcholine esterase (CHE) levels (4500.93 U/L vs 5815.28 U/L, P = 0.000) and significantly higher total bile acid (TBA) levels (275.56 μmol/L vs 147.03 μmol/L, P = 0.000) than those without severe jaundice. The median of the lowest point time tended to be lower in patients with severe jaundice (81.64% vs 96.12%, P = 0.000). HEV infected patients with severe jaundice had a significantly higher viral load (median: 134 vs 112, P = 0.025) than those without severe jaundice. HEV infected patients with severe jaundice showed a trend toward longer median hospital stay (38.17 d vs 18.36 d, P = 0.073). Multivariate logistic regression indicated that there were significant differences in age, sex, viral load, GGT, albumin, TBA, CHE, prothrombin index, alcohol

    Overlap syndromes in which persons manifest clinical, histological, or immunological features of both hepatitis C infection and autoimmune hepatitis are well described. The discordant forms of treatment for hepatitis C and autoimmune hepatitis have made medical management of these patients difficult. We report our experience in using corticosteroids as first line therapy for the hepatitis C-autoimmune hepatitis overlap syndrome. Seven patients with this overlap syndrome (diagnosis based on the presence of serum hepatitis C antibody by RIBA and serum hepatitis C RNA by polymerase chain reaction, and serum hypergammaglobulinemia, elevated ANA or ASMA titers, or histological findings consistent with autoimmune hepatitis) were treated with prednisone with or without azathioprine or cyclosporine, and followed for a median duration of 44.5 months. Five patients (71%) showed improvement of median serum ALT level from 162 U/L to 38 U/L (p = 0.04) and median serum gamma-globulin from 2.1 g/dl to 1.4 g/dl (p = 0.04) by 6 months of therapy. The mean modified histological activity index score also decreased from 11.4 +/- 2.5 to 6.6 +/- 2.6 (p = 0.04) by at least 1 yr of therapy. One patient discontinued prednisone while taking azathioprine and experienced a rebound elevation of serum ALT that did not respond to retreatment with prednisone. Antiviral therapy was subsequently administered and resulted in biochemical and virologic response. Hepatitis C virus RNA remained detectable in all other patients. Corticosteroids are beneficial as a first line therapy for some patients with the hepatitis C-autoimmune overlap syndrome, resulting in appreciable biochemical and histological response but without viral eradication.

    Full Text Available Hepatitis-associated aplastic anemia occurs in up to 10% of all aplastic anemia cases. Syngeneic bone marrow transplantation is rare in patients with severe aplastic anemia and usually requires pre-transplant conditioning to provide engraftment. We report on a 29-year-old male patient with hepatitis-associated severe aplastic anemia who had a series of severe infectious conditions before transplantation, including tracheal inflammation. Life-threatening bleeding, which developed after bronchoscopy, was successfully treated with activated recombinant factor VII and platelet transfusions. Syngeneic peripheral blood stem cell transplantation using immunosuppressive treatment with antithymocyte globulin and cyclosporin A without high-dose pre-transplant conditioning was performed, followed by complete hematologic and hepatic recovery.

    Full Text Available Graves' disease is a common condition and is known to have a wide range of effects on a variety of organs. Hepatic dysfunction ranging from mild to severe due to direct effect of high circulating thyroid hormones as well as a deleterious effect of antithyroid medications (methimazole and propylthiouracil has been well - documented in literature. However, severe autoimmune hepatitis (AIH associated with Graves' disease is rare and limited to few case reports only. A 38-year-old woman presented with abdominal pain and yellowish discolouration of conjunctivae. On investigation, she was found to have Graves' disease and AIH. The liver histopathology showed typical features of AIH. She responded excellently to glucocorticoid therapy with normalisation of thyroid function and liver histology. The case is discussed with relevant literature review.

    Introduction: At least 40% of survivors of biliary atresia have progressive cirrhosis even after undergoing Kasai operation. The values of hepatic apparent diffusion coefficient and apparent-diffusion-coefficient-related indices were applied to biliary atresia patients and correlated with cirrhotic severity scores of model for end-stage liver disease or pediatric end-stage liver disease model, Child-Turcotte, and Child-Pugh systems. Materials and methods: Thirty-three biliary atresia patents (mean = 1140, 61–4314 days of age) received magnetic resonance image examinations due to complications of biliary atresia from April 2008 to August 2009. Two non-breath-hold diffusion weighted imaging sequences were performed with motion-probing gradients in three directions with two b values: 0/100 and 0/500 s/mm 2 ; 1000 ms/61.1 ms, time to repeat/time to echo; number of excitation, 1.0; 8 mm section thickness; 40 cm × 40 cm field of view; 128 × 256 matrix in all biliary atresia patients and 18 control subjects. We used the Spearman rank correlation test to analyze the relationship among the scores of model for end-stage liver disease or pediatric end-stage liver disease model, Child-Turcotte and Child-Pugh scores and right hepatic apparent diffusion coefficients, apparent diffusion coefficient using b factor of 500-albumin product and alanine transaminase/apparent diffusion coefficient with b factor of 500 ratio. Results: The right hepatic apparent diffusion coefficient using b factor of 100, apparent diffusion coefficient with b factor of 500 and product of apparent diffusion coefficient with b factor of 500-albumin level were significantly negatively correlated (p ≤ 0.0125) with model for end-stage liver disease or pediatric end-stage liver disease model, Child-Turcotte, and Child-Pugh scores of biliary atresia patients. The ratio of alanine transaminase level/right hepatic apparent diffusion coefficient with b factor of 500 was also significantly (p ≤ 0

    Regorafenib is the first small-molecule multikinase inhibitor which showed survival benefits in pretreated metastatic colorectal cancer (mCRC) patients. Besides classical adverse events of this drug class, hepatotoxicity has been described as a frequent side effect. Patients with refractory mCRC treated with regorafenib in our institution were reviewed. Severe treatment-related liver toxicity was investigated. Clinical history, liver histology and genetic assessment (sequence analysis) of cytochrome P3A4 (CYP3A4) and uridine diphosphate-glucuronosyltransferase 1A9 (UGT1A9) involved in regorafenib metabolization were here reported for patients with severe hepatotoxicity. Among the 93 reviewed patients, 3 presented severe and icteric toxic hepatitis which was fatal for 1 patient. Histopathological liver lesions were different depending on the onset of hepatotoxicity (acute or subacute): acinar zone 3 necrosis in case of acute symptoms, and portal tract inflammation with porto-central bridging and fibrosis in the delayed presentation. None of the patients had CYP3A4 gene mutations. Similar polymorphisms in UGT1A9 gene promoter region (UGT1A9 variant -118T 9>10 [rs3832043]) were found in both patients who presented acute hepatitis. Moreover, it appears retrospectively that both of them already experienced significant toxicity under irinotecan-based chemotherapy. This is the first report of severe hepatotoxicity with available liver histology and genetic assessment of enzymes involved in regorafenib metabolization. This report also reminds the importance of close liver tests monitoring during regorafenib treatment. © 2016 John Wiley & Sons A/S. Published by John Wiley & Sons Ltd.

    Full Text Available Epstein-Barr virus (EBV is a causative agent of infectious mononucleosis syndrome. This infection often resolves over a period of several months without outcomes, but may occasionally be complicated by a great variety of neurologic, hepatic, hematologic and respiratory complications. In the current report, we present the case histories of three patients with acute hepatitis following EBV infection when previously healthy. The patients showed fever, nausea, weakness, as well as yellowing of the skin, and then in the course of examination, sore throat. They were managed supportively and their clinical condition improved. Liver function tests such as ALT, AST, ALP, were undertaken and bilirubin were elevated. The serological tests for EBV infection were consistent with the acute phase of infection. The monospot test was also positive. The patients were managed supportively, and their critical condition was improved.

    To investigate B-mode and Doppler ultrasonography (US) features correlating with laboratory findings for the diagnosis of severe acute hepatitis (SAH) in patients with hepatitis A virus infection. Thirty-nine consecutive serologically proven patients were enrolled. Decreased parenchymal echotexture, periportal tracking, gallbladder wall change, and splenomegaly were assessed on B-mode images. Blood flow velocities were measured in the main portal (V(PORTAL)) and in the hepatic veins, and the hepatic venous pulsatility index was calculated. SAH was defined as high model for end-stage liver disease (MELD) score ≥ 15 with or without coagulopathy. The relationship between US features and laboratory findings was assessed, and SAH diagnosis was evaluated. Serum alanine transaminase and prothrombin time were significantly different depending on the presence of gallbladder wall change and splenomegaly (p hepatic venous waveform and hepatic venous pulsatility index were significantly correlated with MELD score. For the diagnosis of SAH, the area under the receiver operating characteristic curve of V(PORTAL) was 0.798. It reached 0.869 in the patients with typical GB change. Both B-mode and Doppler US correlated well with several laboratory variables and may be helpful to diagnose SAH in patients with hepatitis A virus infection. © 2014 Wiley Periodicals, Inc.

    Defibrotide (Defitelio(®)) was recently approved in the EU for the treatment of severe hepatic veno-occlusive disease (VOD), also known as sinusoidal obstructive syndrome, in haematopoietic stem cell transplantation (HSCT) therapy. It is indicated in adults, adolescents, children and infants over 1 month of age. Defibrotide is also available in the US via an expanded-access protocol. Defibrotide is thought to protect endothelial cells and restore the thrombo-fibrinolytic balance in VOD. In a multicentre, phase III trial, the complete response rate by day +100 (primary endpoint) was significantly higher, and mortality at day +100 was significantly lower, in patients with severe hepatic VOD and multiorgan failure following HSCT who received intravenous defibrotide 6.25 mg/kg every 6 h than in a group of historical controls. The efficacy of defibrotide in severe hepatic VOD following HSCT was also supported by findings from a phase II dose-finding study, compassionate-use data and information provided from an independent transplant registry. Intravenous defibrotide was generally well tolerated in patients with severe hepatic VOD following HSCT, and was not associated with an increased risk of haemorrhagic adverse events. In conclusion, defibrotide is the only agent approved (in the EU) for use in severe hepatic VOD following HSCT and represents a useful advance in the treatment of this condition.

    Portal hypertension can lead to oesophageal varices (EV) and portal hypertensive gastropathy (PHG). The aim of this study is to determine the relationship between severity of Portal hypertensive gastropathy and size of oesophageal varices. Methods: One hundred and ninety-five patients of hepatitis C positive chronic liver disease having oesophageal varices were assessed for severity of portal hypertensive gastropathy. Results: Mild Portal Hypertensive Gastropathy was observed in 16 (8.2 %), moderate in 54 (27.7 %) and severe in 120 (61.6 %) patients. Grade 1 Oesophageal Varices were present in 79 (40.5%) patients, grade 2 in 44(21.9%) patients, grade 3 in 62 (31.8%) and grade 4 in 10 (5.2%) patients. No significant correlation was observed between grades of gastropathy and size of varices. Conclusion: The frequency of portal hypertensive gastropathy was 97.5% in Hepatitis C positive cirrhotic patients having oesophageal varices. Severity of gastropathy is not related to the grade or size of oesophageal varices. (author)

    Full Text Available The incidence of chronic hepatitis C in St. Petersburg is 124.4 per 100 000 population. The number of patients with liver cirrhosis is significant.Aim of this study: to examine the demographic, clinical and epidemiological characteristics of patients with cirrhosis in the results of chronic hepatitis C.Materials and methods: 100 patients with cirrhosis due to chronic hepatitis C in age 31–70 years were included. Patients with infection hepatitis viruses A and B, HIV, alcohol abuse, drug addicts, previously received antiviral therapy were excluded. Liver cirrhosis was diagnosed on the basis clinical, laboratory and instrumental investigations.Results: most patients (86,2% male and 81,7% female are socially adapted. In 23,2% of patients antibodies to hepatitis C virus were first detected simultaneously with the diagnosis of cirrhosis. Medical procedures were the most common route of infection (25,6% male and 57,1% female. Genotype 1 was dominant (65.7%. Viral load over 800 000 IU/ml was detected in 36,7% of patients. ALT activity was normal or not more than 2 upper limit of normal in 59% of patients, AST – 47%. Normal levels of total bilirubin were recorded in 37% of cases.Conclusions: the first detection of antibodies to hepatitis C virus at the stage of cirrhosis, absence of jaundice, normal or low cytolytic activity once again confirms the need for screening for markers of hepatitis C virus. Dominance of genotype 1 is probably due on the one hand with features routes of transmission, and the other – with the speed of transformation chronic hepatitis to cirrhosis.

    The purpose of this report is to compare a computed tomography (CT) injury severity scale for hepatic and splenic injury with the following outcome measures: requirement for surgical hemostasis, requirement for blood transfusion and late complications. Sixty-nine children with isolated hepatic injury and 53 with isolated splenic injury were prospectively classified at CT according to extent of parenchymal involvement. Clinical records were reviewed to determine clinical outcome. Ninety-seven children (80%) were managed non-operatively without transfusion. One child with hepatic injury required surgical hemostasis, and 17 (25%) required transfusion of blood. Increasing severity of hepatic injury at CT was associated with progressively greater frequency of transfusion (P = 0.002 by {chi}{sup 2}-test). One child with splenic injury underwent surgery and eight (15%) required transfusion of blood. Splenic injury grade at CT did not correlate with frequency (P = 0.41 by {chi}{sup 2}-test) or amount (P = 0.35 by factorial analysis of variance) of transfusion. There was one late complication in the nonsurgical group. A majority of children with hepatic and splenic injury were managed non-operatively without requiring blood transfusion. The severity of injury by CT scan did not correlate with need for surgery. Increasing grade of hepatic injury at CT was associated with increasing frequency of blood transfusion. CT staging was not discriminatory in predicting transfusion requirement in splenic injury. (orig.)

    Choline metabolism is important for very low-density lipoprotein secretion, making this nutritional pathway an important contributor to hepatic lipid balance. The purpose of this study was to assess whether the cumulative effects of multiple single nucleotide polymorphisms (SNPs) across genes of choline/1-carbon metabolism and functionally related pathways increase susceptibility to developing hepatic steatosis. In biopsy-characterized cases of nonalcoholic fatty liver disease and controls, we assessed 260 SNPs across 21 genes in choline/1-carbon metabolism. When SNPs were examined individually, using logistic regression, we only identified a single SNP (PNPLA3 rs738409) that was significantly associated with severity of hepatic steatosis after adjusting for confounders and multiple comparisons (P=0.02). However, when groupings of SNPs in similar metabolic pathways were defined using unsupervised hierarchical clustering, we identified groups of subjects with shared SNP signatures that were significantly correlated with steatosis burden (P=0.0002). The lowest and highest steatosis clusters could also be differentiated by ethnicity. However, unique SNP patterns defined steatosis burden irrespective of ethnicity. Our results suggest that analysis of SNP patterns in genes of choline/1-carbon metabolism may be useful for prediction of severity of steatosis in specific subsets of people, and the metabolic inefficiencies caused by these SNPs should be examined further.—Corbin, K.

    Full Text Available Intrahepatic cholestasis of pregnancy (ICP is a complication of pregnancy resulting in elevation of serum bile acid levels. ICP is often associated with underlying liver disease, including hepatitis C. Bile acids in relationship to the acute infection of hepatitis C virus have not yet been delineated in the literature. A 26-year-old gravida 4 para 2103 with dichorionic, diamniotic twin gestation and history of intravenous drug abuse developed ICP in the setting of acute hepatitis C infection. In addition to clinical symptoms of pruritus and right upper quadrant pain, she developed severe elevation in bile acids, 239 micromol/L, and transaminitis aspartate aminotransferase 1033 U/L, and alanine aminotransferase 448 U/L. She received ursodeoxycholic acid and antenatal testing was performed. Patient delivered vaginally at 33-week gestation following preterm rupture of membranes. Neonates were admitted to NICU and had uncomplicated neonatal courses. In the setting of ICP with significant transaminitis and severe elevation of bile acids, consideration of acute viral hepatitis is important, especially considering the worsening opioid epidemic and concurrent increase in intravenous drug use in the United States. Further study is needed regarding the acute form of HCV infection and its effect on ICP and associated bile acids.

    The purpose of this study was to assess the efficacy of absorbable mesh wrapping (MW) versus perihepatic packing (HP) for severe hepatic injury. From January 2001 to December 2012, data were collected for MW patients with hepatic injury. Patients who underwent HP were matched with MW patients by injury mechanism, liver injury grade, Injury Severity Score, and age. Twenty-six MW and twenty-six HP patients were matched. Eighteen blunt and 8 penetrating injuries were present in each group. There were 9 (35%) mortalities in the MW group and 16 (62%) in the HP groups (P = .03). Average transfusions were 12.0 and 24.5 (P = .03) packed red blood cells in the MW and HP groups, respectively. Average laparotomies per survivors were 1.3 for the MW and 3.1 for the HP groups (P = .01). Average length of stay for survivors was 19 and 47 (P = .04) days in the MW and HP groups, respectively. MW for hepatic injuries can significantly decrease mortality, transfusions, laparotomies, and length of stay. Copyright © 2015 Elsevier Inc. All rights reserved.

    Full Text Available Introduction: The association of acute viral hepatitis and acute pancreatitis is well described. This study was conducted to find out the frequency of pancreatic involvement in acute viral hepatitis in the Nepalese population. Methods: Consecutive patients of acute viral hepatitis presenting with severe abdominal pain between January 2005 and April 2010 were studied. Patients with history of significant alcohol consumption and gall stones were excluded. Acute viral hepatitis was diagnosed by clinical examination, liver function test, ultrasound examination and confirmed by viral serology. Pancreatitis was diagnosed by clinical presentation, biochemistry, ultrasound examination and CT scan. Results: Severe abdominal pain was present in 38 of 382 serologically-confirmed acute viral hepatitis patients. Twenty five patients were diagnosed to have acute pancreatitis. The pancreatitis was mild in 14 and severe in 11 patients. The etiology of pancreatitis was hepatitis E virus in 18 and hepatitis A virus in 7 patients. Two patients died of complications secondary to shock. The remaining patients recovered from both pancreatitis and hepatitis on conservative treatment. Conclusions: Acute pancreatitis occurred in 6.5 % of patients with acute viral hepatitis. Cholelithiasis and gastric ulcers are the other causes of severe abdominal pain. The majority of the patients recover with conservative management. Keywords: acute viral hepatitis, acute pancreatitis, pain abdomen, hepatitis E, hepatitis A, endemic zone

    Purpose: Although hepatic perfusion abnormalities have been reported in patients with acute pancreatitis, hepatic perfusion with severe acute pancreatitis (SAP) has not been quantitatively evaluated in humans. Therefore, we investigated hepatic perfusion in patients with SAP using perfusion CT. Materials and methods: Hepatic perfusion CT was performed in 67 patients with SAP within 3 days after symptom onset. The patients were diagnosed as having SAP according to the Atlanta criteria. Fifteen cases were established as a control group. Perfusion CT was obtained for 54 s beginning with a bolus injection of 40 ml of contrast agent (600–630 mgI/kg) at a flow rate of 4 ml/s. Perfusion data were analyzed by the dual-input maximum slope method to obtain hepatic arterial perfusion (HAP) and hepatic portal perfusion (HPP). Finally, we compared HAP and HPP in SAP patients with those in the control group, respectively. Results: Average HAP was significantly higher in SAP patients than in the control group (75.1 ± 38.0 vs. 38.2 ± 9.0 ml/min/100 ml; p < 0.001). There was no significant difference in average HPP between SAP patients and the control group (206.7 ± 54.9 vs. 204.4 ± 38.5 ml/min/100 ml; p = 0.92). Conclusion: Using quantitative analysis on perfusion CT, we first demonstrated an increase of HAP in the right hepatic lobe in SAP patients.

    A study was conducted to estimate the functional reserve of the liver of patients with severe hepatitis by computed tomography (CT), in particular employing the integrated CT number of the whole liver (ICTN). ICTN was calculated by integrating the product of 'area' times 'mean CT number' of the liver in each CT slice for the entire height of the liver. The following results were obtained: (1) In patients with fulminant hepatitis (FH) as well as those with subacute hepatitis (SAH), ICTN was found to be significantly lower as compared to that of patients with acute hepatitis (AH) or non-hepatic diseases. In addition, in FH and SAH patients, ICTN showed a larger degree of decrease when compared with such conventional parameters as either estimated liver volume or mean hepatic CT number. Thus, ICTN seems to more sensitively reflect the changes in functional reserve of the liver. (2) ICTN showed significant positive correlations with prothrombin time and plasma BCAA/AAA ratio, and a significant negative correlation with plasma methionine level. (3) Time course of changes in ICTN correlated well with the clinical features of severe hepatitis. In particular, patients with initial ICTN values above 20 lcenter dotHU/m/sup 2/ of body surface area showed significantly higher survival rate than those with initial ICTN below 20. In conclusion, ICTN well indicates the functional reserve of the liver, and is further suggested to be valuable as a parameter to predict the prognosis of patients with severe hepatitis. (author).

    Objective: To investigate the correlationship between blood hepatic fibrosis markers and blood lipids levels. Methods: Serum hepatic fibrosis markers (HA, PC III, IV-C, LN) levels were determined with RIA and serum lipids (TG, TCh HDL; LDL, apoA1, apoB) were measured with biochemical methods in 98 patients with hepatitis in various stages and 50 controls. Liver biopsy was done in all the hepatitis patients. Results: Hepatic fibrosis was classified into 5 grades (S0-S4) according to the pathology shown in the biopsy specimen. The serum lipid levels decreased along with the increase of severity of fibrosis from S0 to S4. Levels in S4 patients were significantly lower than those in controls (P 0.05). Conclusion: The serum hepatic fibrosis markers levels increased and lipids levels decreased along with the progress of hepatitis from acute to cirrhosis. (authors)

    This study was designed to evaluate whether percutaneous injection of hemostatic agents under the guidance of contrast-enhanced ultrasound (CEUS) can stop hemorrhage from severe hepatic trauma. Eighteen dogs were impacted by a miniature impactor to create blunt hepatic trauma. Fourteen with appropriate liver lesions were divided into two groups: the treatment group (n=7) and the control group (n=7). In the treatment group, hemocoagulase atrox and α-cyanoacrylate were respectively injected into the injury sites and transected micro-vessels under the guidance of CEUS. In the control group, normal saline was injected into the injury sites. CEUS and CT were performed at 3, 7, 14, and 21 days after the focal injection. Surviving animals were killed on the 21st day for pathologic examination. All animals of the treatment group survived. Three dogs of the control group died in the first 24 h. In the treatment group, CEUS and CT demonstrated that hepatic lesions became smaller gradually from the 3rd to the 21st day after injection. The focal injection of hemostatic agents under the guidance of CEUS can stop hemorrhage from hepatic trauma of grade III∝IV or IV. During the period of 3 weeks, no side effect was found. (orig.)

    Among the histological lesions seen in chronic hepatitis C (CHC), the presence of steatosis, bile duct lesions and lymphoid aggregates are characteristic. Recent reports suggest that steatosis is an independent risk factor for liver fibrosis in CHC. The aim of our study was to determine the relative contribution of steatosis and moderate alcohol consumption to the severity of liver fibrosis in patients infected with genotype 1 hepatitis C virus. We evaluated the patients with biopsy proven CHC and no or only moderate alcohol intake (<40 g/day). The demographical parameters of the study population, the indices of alcohol consumption: erythrocyte median corpuscular volume (MCV), gamma-glutamyl transpeptidase (GGT), the histological characteristics were noted and a statistical analysis was performed in order to determine the factors independently associated with severe fibrosis and with severe steatosis. From the 200 patients included in the study, 82 were males and 118 females, with a mean age of 47.75+/-10.42 years. At univariate analysis, advanced (grade 2, 3) fibrosis correlated with: the age at the time of biopsy, increased inflammatory activity (HAI), moderate/severe steatosis, alcohol intake, elevated GGT and MCV values. After multivariate logistic regression only age, HAI and steatosis were independently associated with advanced fibrosis stage. Regarding hepatic steatosis, from the factors found to correlate with severe steatosis at univariate analysis (alcohol intake, elevated GGT and MCV levels, severe fibrosis), after multivariate logistic regression only the elevated level of GGT was an independent prognostic factor for severe steatosis. Steatosis is an important risk factor for the severity of liver disease in CHC patients. Among patients with genotype 1 hepatitis C virus infection and moderate alcohol intake, those with serum levels of GGT over two times the normal value are at high risk for severe steatosis.

  13. Renalase as a Novel Biomarker for Evaluating the Severity of Hepatic Ischemia-Reperfusion Injury

    Full Text Available Hepatic ischemia-reperfusion (I/R injury is a serious complication in clinical practice. However, no efficient biomarkers are available for the evaluation of the severity of I/R injury. Recently, renalase has been reported to be implicated in the I/R injury of various organs. This protein is secreted into the blood in response to increased oxidative stress. To investigate the responsiveness of renalase to oxidative stress, we examined the changes of renalase in cell and mouse models. We observed a significant increase of renalase expression in HepG2 cells in a time- and dose-dependent manner when treated with H2O2. Renalase expression also increased significantly in liver tissues that underwent the hepatic I/R process. The increased renalase levels could be efficiently suppressed by antioxidants in vitro and in vivo. Furthermore, serum renalase levels were significantly increased in the mouse models and also efficiently suppressed by antioxidants treatment. The variation trends are consistent between renalase and liver enzymes in the mouse models. In conclusion, renalase is highly sensitive and responsive to oxidative stress in vitro and in vivo. Moreover, renalase can be detected in the blood. These properties make renalase a highly promising biomarker for the evaluation of the severity of hepatic I/R injury.

    To determine the frequency of worsening liver function among hospital in-patients with severe dengue hepatitis receiving paracetamol. Methods: This retrospective study was conducted at the Department of Medicine, Aga Khan University Hospital, Karachi, and comprised records of dengue patients with severe hepatitis who received paracetamol for control of fever between June 2007 and December 2014. Alanine aminotransferase at baseline and following paracetamol administration was noted, as well as dosage and duration of paracetamol, along with participants' demographic details. Frequency of patients who developed worsening or improvement of alanine aminotransferase was also noted. SPSS 19 was used for data analysis. Results: Of the 113 subjects, 73(64.6%) were male and 40(35.4%) were female. Overall improvement was observed in subsequent alanine aminotransferase levels (491 units per litre, IQR 356.5 TO 775 vs 151 units per litre, IQR 49.5 to 299.5). Most commonly prescribed dose of paracetamol was 2g (IQR 1 to 5 grams), which was taken for a median duration of 1 day (IQR 1 to 3 days). Moreover, 100(88.5 %) patients showed improvement in alanine aminotransferase. Only 13(11.5 %) patients developed worsening of alanine aminotransferase. Of those with worsening liver function, 8(61.5 %) were discharged home with no clinical deterioration and 5(38.5 %) deaths were observed. However, causes of deaths were unrelated to liver dysfunction. Conclusion: The frequency of worsening liver function following paracetamol administration in patients with severe dengue hepatitis was relatively low. (author)

    Hepatitis-associated aplastic anemia (HAA) is a rare variant of aplastic anemia in which patients present with severe pancytopenia after an episode of acute hepatitis. The marrow failure is often rapid, severe, and usually fatal if untreated. The preceding hepatitis is largely under-studied. Retrospective study of the clinical and histopathologic features of hepatitis in pediatric patients who subsequently developed aplastic anemia and comparison with consecutive cases of acute liver failure and random cases of autoimmune hepatitis during the same time frame. All 7 patients of HAA had significant elevations in aminotransferases and conjugated hyperbilirubinemia at initial presentation. Echoing liver function indices, cholestatic hepatitis with sinusoidal obstruction-type endothelial injury was seen histomorphologically. Autoimmune hepatitis serology such as anti-F-actin, anti-liver/kidney microsome, and hypergammaglobulinemia was negative in all patients. Five of 7 patients (71.4%) had, however, elevated antinuclear antibody, all with a speckled pattern. Hepatitis virus serology was negative in all patients. By immunohistochemical staining, the lobular CD8/CD4 lymphocyte ratio was markedly elevated in all of the initial samples with significant reduction in this ratio (P = 0.03) in 3 patients post treatment (ursodiol, antibiotics, and/or immunosuppressive therapy). Hepatitis preceding HAA is characterized by marked elevation of aminotransferases, conjugated hyperbilirubinemia, elevated antinuclear antibody with a speckled pattern, cholestatic hepatitis with sinusoidal obstruction morphology, and CD8 dominant lobular infiltrates. The present study suggests HAA may result from cytotoxic T-cell-mediated sinusoidal endothelial and hepatocytic injury.

    To investigate the significance of combined detection of laminin (LN), collagen type IV (CIV), hyaluronic acid (HA) and precollagen type III (PCIII) in the diagnosis of hepatic fibrosis. The serum levels of LN, CIV, HA and PCIII in 143 patients with hepatic disease and 41 healthy controls were measured by radioimmunoassay (RIA). The results showed that the serum levels of LN, CIV, HA and PCIII in patients with hepatic disease were significantly higher than those of the control group (P<0.01), and the serum levels of those markers were related to the severity of the chronic hepatic disease. The highest serum levels were found in serious chronic hepatitis group and hepatic fibrosis group,and the increase of serum HA and PCIII was most remarkable. Combined detection of LN, CIV, HA and PCIII is a sensitive and reliable method in the diagnosis of hepatic fibrosis, but the four serum indices can not be used in differentiating serious chronic hepatitis and hepatic fibrosis.

    Smith, Donald B; Simmonds, Peter

    2015-04-01

    Fulminant hepatitis is a rare outcome of infection with hepatitis E virus. Several recent reports suggest that virus variation is an important determinant of disease progression. To critically examine the evidence that virus-specific factors underlie the development of fulminant hepatitis following hepatitis E virus infection. Published sequence information of hepatitis E virus isolates from patients with and without fulminant hepatitis was collected and analysed using statistical tests to identify associations between virus polymorphisms and disease outcome. Fulminant hepatitis has been reported following infection with all four hepatitis E virus genotypes that infect humans comprising multiple phylogenetic lineages within genotypes 1, 3 and 4. Analysis of virus sequences from individuals infected by a common source did not detect any common substitutions associated with progression to fulminant hepatitis. Re-analysis of previously reported associations between virus substitutions and fulminant hepatitis suggests that these were probably the result of sampling biases. Host-specific factors rather than virus genotype, variants or specific substitutions appear to be responsible for the development of fulminant hepatitis. © 2014 The Authors.

    Mathematical modelling and simulation for Hepatitis B discuss in this paper. Population devided by four variables, namely: Susceptible, Exposed, Infected and Recovered (SEIR). Several factors affect the population in this model is vaccination, immigration and emigration that occurred in the population. SEIR Model obtained Ordinary Differential Equation (ODE) non-linear System 4-D which then reduces to 3-D. SEIR model simulation undertaken to predict the number of Hepatitis B cases. The results of the simulation indicates the number of Hepatitis B cases will increase and then decrease for several months. The result of simulation using the number of case in Makassar also found the basic reproduction number less than one, that means, Makassar city is not an endemic area of Hepatitis B.

    Objective: To assess the clinical application of 131 I and artificial liver support system (ALSS) in the treatment of hyperthyroidism complicated with severe hepatitis. Methods: Forty-three hyperthyroidism patients complicated with severe hepatitis were divided into two groups: 18 cases treated with anti-thyroid drugs (ATD) as group A, and 25 cases with 131 I therapy as group B, the group B was further divided into: 12 cases were treated without ALSS as group B1, while 13 cases with ALSS as in group B2. The cure and improved rates were compared between group A and B, and the cure rates were compared between group B1 and B2, respectively. Moreover, the changes of serum level of thyroid and liver function indexes before and 1 week after each ALSS therapy were observed. Results: The cure and improved rate of group B (96.0%) was significantly higher than that of group A (61.1%), and the cure rate of group B2 (84.6%) was significantly higher than that of group B1 (33.3%, P 3 , FT 4 , total bilirubin (TBIL), direct bilirubin (DBIL), aspartate aminotransferase (AST) and alanine aminotransferase (ALT) improved obviously after ALSS therapy (P 131 I is more effective. Besides, ALSS is safe, and it can improve cure rate. (authors)

    Full Text Available Abstract Background Oxidative stress can be defined as an increase in oxidants and/or a decrease in antioxidant capacity. There is limited information about the oxidative status in subjects with hepatitis B virus infection. We aimed to evaluate the oxidative status in patients with various clinical forms of chronic hepatitis B infection. Methods Seventy-six patients with hepatitis B virus infection, in whom 33 with chronic hepatitis, 31 inactive carriers and 12 with cirrhosis, and 16 healthy subjects were enrolled. Total antioxidant response and total peroxide level measurement, and calculation of oxidative stress index were performed in all participants. Results Total antioxidant response was significantly lower in cirrhotics than inactive HbsAg carriers and controls (p = 0.008 and p = 0.008, respectively. Total peroxide level and oxidative stress index was significantly higher in cirrhotic (p 0.05/6. Total peroxide level and oxidative stress index were also comparable in inactive HBsAg carriers and controls (both, p > 0.05/6. Serum alanine amino transferase level was positively correlated with total peroxide level and oxidative stress index only in chronic hepatitis B subjects (p = 0.002, r = 0.519 and p = 0.008, r = 0.453, respectively. Conclusion Oxidative stress occurs secondarily to increased total lipid peroxidation and inadequate total antioxidant response and is related to severity of the disease and replication status of virus in hepatitis B infection.

    Adenosin deaminase (ADA) deficiency is the cause for Severe Combined Immunodeficiency (SCID) in about 15% of patients with SCID, often presenting as T (-)B (-)NK (-)SCID. Treatment options for ADA-SCID are enzyme replacement, bone marrow transplantation or gene therapy. We here describe the first patient with ADA-SCID and fatal hepatic failure despite bone marrow transplantation from a 10/10 HLA identical related donor. As patients with ADA-SCID may be at yet underestimated increased risk for rapid hepatic failure we speculate whether hepatitis in ADA-SCID should lead to the immediate treatment with enzyme replacement by pegylated ADA. © Georg Thieme Verlag KG Stuttgart · New York.

    Tracer quantities of colloidal 198 Au were used to estimate the hepatic blood flow in normal children and in children with active or progressive chronic hepatitis and also to obtain scintigrams of the liver. In active chronic hepatitis a significant decrease in HBF values was observed, suggesting that the method may be used as a diagnostic criterion which is superior to hepatic scintigraphy. In progressive chronic hepatitis HBF values even lower than those in active hepatitis were observed. Together with more characteristic clinical findings and abnormal results of biochemical function tests, they underline the value of the method in estimating the severity and the evolution of the disease.

    Purpose: The aim of this study was to assess the value of abdominal CT and MRI in determining the severity of cirrhosis secondary to hepatitis compared to Child-Pugh classification. Materials and methods: The study included 23 patients who were clinically and histologically diagnosed with chronic liver disease secondary to viral hepatitis. Each patient underwent dynamic abdominal CT imaging and MRI within the same week. CT and MRI findings were retrospectively reviewed. The same parameters were used from the CT and the MR images for each patient. The parameters included liver volume index (posterior segment of the right lobe, medial and lateral segments of the left lobe), spleen volume index, ascites, portosystemic collaterals, contour irregularities of the liver and confluent fibrosis within the liver. The findings were compared with the patients' Child-Pugh grades. Multiple regression analysis was used for statistical analysis. Results: On MRI, liver volume index (P = 0.0001), and ascites (P = 0.009) were strongly correlated with Child-Pugh grades. With CT, only ascites was correlated with Child-Pugh grades (P = 0.002). Conclusion: This study indicates that liver volume index on MRI, and ascites on CT and MRI are good indicators of clinical severity of cirrhosis secondary to hepatitis. To show the effect of the other parameters, more research is needed with larger patient groups

    We present the case of an 18-year-old female with severe liver trauma after a motorcycle accident. Due to initial hemodynamic instability, fluid resuscitation and transfusion of two units of red packed cells was required. After stabilization, a CT scan was performed, showing grade V liver injuries according to the American Association for the Surgery of Trauma grading system. Angiography revealed multiple extravasations during the early arterial phase, as well as active extravasation from the proximal left hepatic artery in the late arterial phase. The patient was successfully treated by arterial embolization using metal microcoils, after which no further need for blood transfusion ensued. This report highlights that, in carefully selected cases, arterial embolization can improve the clinical condition of patients, reduce the need for blood transfusion and lessen the possibility of an operation, even if severe liver trauma has ensued.

    Full Text Available Background. Hyperammonemia resulting from chronic liver disease (CLD can potentially challenge and damage any organ system of the body, particularly the brain. However, there is still some controversy regarding the diagnostic or prognostic values of serum ammonia in patients with over hepatic encephalopathy, especially in the setting of acute-on-chronic or chronic liver failure. Moreover, the association of serum ammonia with worsening Child-Pugh grade of liver cirrhosis has not been studied. Objective. This study was conducted to solve the controversy regarding the association between hyperammonemia and cirrhosis, especially hepatic encephalopathy in chronically failed liver. Material and Methods. In this study, 171 cirrhotic patients had their serum ammonia measured and analyzed by SPSS version 16. Chi-squared test and one-way ANOVA were applied. Results. The study had 110 male and 61 female participants. The mean age of all the participants in years was 42.33±7.60. The mean duration (years of CLD was 10.15±3.53 while the mean Child-Pugh (CP score was 8.84±3.30. Chronic viral hepatitis alone was responsible for 71.3% of the cases. Moreover, 86.5% of participants had hepatic encephalopathy (HE. The frequency of hyperammonemia was 67.3%, more frequent in males (N=81, z-score = 2.4, and P<0.05 than in females (N=34, z-score = 2.4, and P<0.05, and had a statistically significant relationship with increasing CP grade of cirrhosis (χ2(2 = 27.46, P<0.001, Phi = 0.40, and P<0.001. Furthermore, serum ammonia level was higher in patients with hepatic encephalopathy than in those without it; P<0.001. Conclusion. Hyperammonemia is associated with both increasing Child-Pugh grade of liver cirrhosis and hepatic encephalopathy.

  9. How hepatitis D virus can hinder the control of hepatitis B virus.

    Directory of Open Access Journals (Sweden)

    Maria Xiridou

    Full Text Available BACKGROUND: Hepatitis D (or hepatitis delta virus is a defective virus that relies on hepatitis B virus (HBV for transmission; infection with hepatitis D can occur only as coinfection with HBV or superinfection of an existing HBV infection. Because of the bond between the two viruses, control measures for HBV may have also affected the spread of hepatitis D, as evidenced by the decline of hepatitis D in recent years. Since the presence of hepatitis D is associated with suppressed HBV replication and possibly infectivity, it is reasonable to speculate that hepatitis D may facilitate the control of HBV. METHODOLOGY AND PRINCIPAL FINDINGS: We introduced a mathematical model for the transmission of HBV and hepatitis D, where individuals with dual HBV and hepatitis D infection transmit both viruses. We calculated the reproduction numbers of single HBV infections and dual HBV and hepatitis D infections and examined the endemic prevalences of the two viruses. The results show that hepatitis D virus modulates not only the severity of the HBV epidemic, but also the impact of interventions for HBV. Surprisingly we find that the presence of hepatitis D virus may hamper the eradication of HBV. Interventions that aim to reduce the basic reproduction number of HBV below one may not be sufficient to eradicate the virus, as control of HBV depends also on the reproduction numbers of dual infections. CONCLUSIONS AND SIGNIFICANCE: For populations where hepatitis D is endemic, plans for control programs ignoring the presence of hepatitis D may underestimate the HBV epidemic and produce overoptimistic results. The current HBV surveillance should be augmented with monitoring of hepatitis D, in order to improve accuracy of the monitoring and the efficacy of control measures.

    Serotonin syndrome (SS) is an underrecognized and potentially fatal disorder that occurs secondary to combinational use or overdose of a single serotonergic medication. The presentation may be complicated by hepatic encephalopathy in cirrhotic patients, which may also affect metabolism of these serotonergic agents. The authors report a rare case of severe SS complicated by hepatic encephalopathy secondary to cirrhosis in a 52-year-old woman after an increase in her home dosage of fluoxetine and addition of other psychiatric medications.

    Hypoxic hepatitis (HH), also known as ischaemic hepatitis or shock liver, is an acute liver injury caused by hepatic hypoxia. Cardiac failure, respiratory failure and septic shock are the main underlying conditions. In each of these conditions, several haemodynamic mechanisms lead to hepatic...... hypoxia. A shock state is observed in only 50% of cases. Thus, shock liver and ischaemic hepatitis are misnomers. HH can be a diagnostic pitfall but the diagnosis can be established when three criteria are met. Prognosis is poor and prompt identification and treatment of the underlying conditions...

    The presence in serum of the Hepatitis B surface antigen (HBsAg), the outer envelope of the hepatitis B virus (HBV), indicates viral infection, used in laboratory tests to confirm this. We report a case of discrepancy among HBsAg test results detected between measurements in a subject with HB infection. Gene analysis demonstrated several S region gene mutations, not detected previously. We tested 12 measurements e.g., EIA, CLIA, CLEIA, F-EIA, MAT, and IC for whether they could detect our subject's HBsAg and found that it was not recognized by a method using only a single monoclonal antibody to detect HBsAg in two detection processes, in contrast to the 11 other measurements, which used two different antibodies. This case shows that amino acid substitution may cause a false negative result for HBsAg. Gene mutations known to occur in HBV, should thus trigger an awareness of the need to keep in mind that false negative results can happen in case such as ours.

    The accuracy of measurement of the functional hepatic volume by single photon emission computed tomography (SPECT) with 99m Tc-galactosyl serum albumin ( 99m Tc-GSA) was evaluated. 99m Tc-GSA planar scintigraphic images were obtained dynamically and the hepatic SPECT imaging was then performed in 25 patients with hepatobiliary tumors. The patients were divided into 4 groups with normal hepatic function, mild, moderate and severe hepatic dysfunction. The functional hepatic volume determined by SPECT was compared with the morphological hepatic volume determined by computed tomography. The ratio of the hepatic volumes obtained by the two methods was calculated. The mean hepatic volume ratio was 96.6±2.3% in the normal hepatic function group and 95.9±2.2% in the mild dysfunction group (n.s.). In both the moderate and severe hepatic dysfunction groups, the hepatic volume ratio was smaller than that in the normal group (87.9±5.2%, p 15 (r=0.83, p 15 (r=0.74, p 15 (r=0.75, p 99m Tc-GSA faithfully reflects the functioning hepatocyte mass. 99m Tc-GSA scintigraphy and hepatic SPECT therefore provide information regarding global and regional reserve hepatic function.

    Full Text Available Objective: To assess the presence of hepatitis B surface antigen, one of the serologic markers of hepatitis B virus (HBV infection, in postmortem blood samples from autopsy cases using ELISA, and to compare the results with those obtained by PCR, which is the gold standard method in assessing HBV infection. Methods: The HBV test results of the blood samples from 880 autopsy cases determined in our laboratory, were retrospectively studied. Results: When compared with the gold standard method PCR, the sensitivity and specificity of postmortem ELISA were 100% and 84.1%, respectively. Conclusions: The increasingly used molecular diagnostic methods, such as PCR, should be used in cases where serological tests remain insufficient.We think that prospective studies on the comparison of ELISA and PCR assessment of postmortem blood samples with larger material should be carried out.

    Full Text Available Abstract Hepatitis B virus (HBV and hepatitis C virus (HCV coinfection is not uncommon as a result of similar routes of infection. Patients who are coinfected represent a unique group with diverse serologic profiles. Combined chronic hepatitis B and C leads to more severe liver disease and an increased risk of hepatocellular carcinoma. Furthermore, coinfected patients represent a treatment challenge. No standard recommendations exist for treatment of viral hepatitis due to dual HBV/HCV infection, and therefore treatment must be individualized based on patient variables such as serologic and virologic profiles, patient's prior exposure to antiviral treatment, and the presence of other parenterally transmitted viruses such as hepatitis D virus and human immunodeficiency virus. The natural history and treatment of patients with HBV and HCV coinfection is reviewed.

    Aim: To evaluate whether contrast-enhanced ultrasound (CEUS)-guided radiofrequency ablation (RFA) can be performed effectively in small hepatic malignancies that are invisible or poorly visualized at traditional grey-scale ultrasonography (US). Materials and methods: The institutional ethics committee approved the study, and all patients provided written informed consent before their enrolment. The study focused on 55 patients (43 men, 12 women, age 57.4 ± 10.9 years) with 60 hepatic lesions from May 2010 to March 2011. All lesions were treated with multipolar radiofrequency ablation (RFA). During the RFA procedure, with the injection of ultrasound contrast agent (sulphur hexafluoride; SonoVue, Bracco Imaging Spa, Milan, Italy), RFA was conducted under CEUS guidance when the optimal depiction of a lesion was obtained. Artificial pleural effusions were used in those cases obstructed by the lungs. Twenty-four hours after RFA, contrast-enhanced MRI was used as the reference standard to evaluate the primary effectiveness rate and complete tumour necrosis. The follow-up time was 12–24 months (median 15 months). Results: Among 60 hepatic malignancies, CEUS detected 57 lesions (95%), which was higher than that at US (26.6%). Artificial pleural effusions were performed in three cases, resulting in the detection of three additional lesions. The insertion of RFA electrodes was monitored by CEUS in all lesions. Immediately after RFA, complete tumour necrosis were achieved in all 60 lesions as apparent at MRI, for a primary effectiveness rate of 100%. Conclusion: CEUS-guided RFA is a promising technique for targeting and improving the efficiency of treatment of hepatic malignancies. - Highlights: • CEUS guided RFA improved the detectability of hepatic malignancies indistinctive on gray-scale ultrasound. • Pre-operation CEUS helped localization of indistinctive hepatic malignancies. • CEUS guided RFA of hepatic malignancies achieved a more complete ablation

    Science.gov (United States)

    2016-01-01

    Aim Hepatitis A is among the diseases that can be prevented with vaccination in our time. Acute hepatitis A progresses more severely in individuals with a liver disease. Therefore, patients with a chronic liver disease (because of hepatitis B or hepatitis C) are advised vaccination with the hepatitis A vaccine. This study is aimed to determine the seroprevalence of hepatitis A virus (HAV) antibodies in patients infected with hepatitis C virus or hepatitis B virus in Konya province of Turkey. Methods A total of 537 patients who had chronic viral hepatitis between January 2011 and December 2014 were included in the study. Serum samples were collected from each patient and tested for anti-HAV using the chemiluminescent microparticle immunoassay. Results The overall seroprevalence of total anti-HAV IgG was 94.2%. The overall prevalence of anti-HAV IgG in patients with chronic hepatitis B virus and hepatitis C virus infection was 97.5 and 93.6%, respectively. Anti-HAV IgG positivity was 97.4% in cirrhotic patients and 93.9% in noncirrhotic individuals. Conclusion At the end of the study, being older than 40 years and living in a rural area were found to be independent risk factors for anti-HAV IgG seropositivity. In conclusion, we recommend that patients younger than 40 years and/or those living in cities and having a chronic liver disease should be vaccinated with the hepatitis A vaccine. PMID:26703930

    Objective: To study the correlationship between the serum levels of PAB, CHE, TBA, ALT and the severity of the disease process in patients with chronic virus B hepatitis. Methods: Serum levels of PAB, CHE, ALT (with biochemical methods) and TBA (with RIA) were examined in 93 patients with biopsy proven virus B hepatitis and 46 controls. Results: The 93 patients were of two groups: a less advanced group (n=51) and a more advanced group (n=42). Serum TBA, ALT levels were significnatly higher and serum PAB, CHE levels were significantly lower in the more advanced group than those in the less advanced group (P 0 to s 4 . Changes of levels of ALT were of no regular pattern, but serum levels of TBA regularly increased and levels of PAB, CHE regularly decreased as the fibrosis grading proceeded from s 0 to s 4 and the differences between the levels in s 4 and any other grading were significant (P<0.01). Conclusion: Combined determination of these serum markers might reflect the degree of inflammatory process and hepatic fibrosis in patients with virus B hepatitis, leading to earlier detection of cirrhosis.

    2018-05-07

    Over the past two decades, progress in understanding human infections with hepatitis A virus (HAV) and hepatitis E virus (HEV) has been eclipsed by the priority of combating persistent hepatitis B virus (HBV) and hepatitis C virus (HCV) infections. During that time, the global burden of liver disease caused by enteric hepatitis viruses has not abated. Because of vaccines, hepatitis A has become increasingly a disease of adults instead of early childhood in many regions of the world, resulting in an age-related shift toward more severe disease. HEV has remained endemic in many developing countries, and in well-developed, economically advanced countries it is now recognized as a cause of chronic, progressive liver disease in individuals with compromised immunity. The goal of this collection of articles is to review recent progress and to shine a bright light on gaps in our understanding of how these viruses replicate, cause disease, interact with the liver and host immune system, and are transmitted, along with prospects for improved control in human populations. Renewed efforts to study and compare HAV and HEV biology in humans and animal models have high potential to enhance our understanding of host-pathogen balance in the liver, and may contribute ultimately to the control of other infectious diseases of the liver.

  4. Severe Juxtahepatic Venous Injury: Survival after Prolonged Hepatic Vascular Isolation Without Shunting

    Directory of Open Access Journals (Sweden)

    J. E. J. Krige

    1990-01-01

    Full Text Available Survival following major juxtahepatic venous injury is rare in blunt liver trauma despite the use of intracaval shunting. Prolonged liver arterial inflow control, total hepatic venous isolation and lobectomy without shunting was used in a patient to repair a combined vena caval and hepatic venous injury after blunt liver injury. An extended period of normothermic hepatic ischemia was tolerated. Early recognition of retrohepatic venous injury and temporary liver packing to control bleeding and correct hypovolemia are essential before caval occlusion. Hepatic vascular isolation without shunting is an effective simple alternative technique allowing major venous repair in complex liver trauma.

    Full Text Available We report the case of an 86-year-old man with a past history of coronary disease admitted to our internal medicine department for severe asthenia and weakness due to rhabdomyolysis. Three days earlier, he had been discharged from a gastroenterology unit with a diagnosis of amoxicillin–clavulanate-induced acute cholestatic hepatitis. A review of his drugs revealed that he had taken atorvastatin 10 mg daily in the previous six years, without clinical or laboratory signs of myopathy. Atorvastatin was therefore stopped, with gradual improvement of the rhabdomyolysis. All concomitant drug therapy needs to be reassessed in elderly patients, especially when they become acutely ill.

    Full Text Available Hepatitis associated aplastic anemia (HAAA is a rare syndrome in which severe aplastic anemia (SAA complicates the recovery of acute hepatitis (AH. HAAA is described to occur with AH caused by viral infections and also with idiopathic cases of AH and no clear etiology of liver injury. Clinically, AH can be mild to fulminant and transient to persistent and precedes the onset SAA. It is assumed that immunologic dysregulation following AH leads to the development of SAA. Several observations have been made to elucidate the immune mediated injury mechanisms, ensuing from liver injury and progressing to trigger bone marrow failure with the involvement of activated lymphocytes and severe T-cell imbalance. HAAA has a very poor outcome and often requires bone marrow transplant (BMT. The findings of immune related myeloid injury implied the use of immunosuppressive therapy (IST and led to improved survival from HAAA. We report a case of young male who presented with AH resulting from the intake of muscle building protein supplements and anabolic steroids. The liver injury slowly resolved with supportive care and after 4 months of attack of AH, he developed SAA. He was treated with IST with successful outcome without the need for a BMT.

    2007-01-01

    Considering the geographical asymmetric distribution of viral hepatitis A, B and E, having a much higher prevalence in the less developed world, travellers from developed countries are exposed to a considerable and often underestimated risk of hepatitis infection. In fact a significant percentage of viral hepatitis occurring in developed countries is travel related. This results from globalization and increased mobility from tourism, international work, humanitarian and religious missions or other travel related activities. Several studies published in Europe and North America shown that more than 50% of reported cases of hepatitis A are travel related. On the other hand frequent outbreaks of hepatitis A and E in specific geographic areas raise the risk of infection in these restricted zones and that should be clearly identified. Selected aspects related with the distribution of hepatitis A, B and E are reviewed, particularly the situation in Portugal according to the published studies, as well as relevant clinical manifestations and differential diagnosis of viral hepatitis. Basic prevention rules considering enteric transmitted hepatitis (hepatitis A and hepatitis E) and parenteral transmitted (hepatitis B) are reviewed as well as hepatitis A and B immunoprophylaxis. Common clinical situations and daily practice "pre travel" advice issues are discussed according to WHO/CDC recommendations and the Portuguese National Vaccination Program. Implications from near future availability of a hepatitis E vaccine, a currently in phase 2 trial, are highlighted. Potential indications for travellers to endemic countries like India, Nepal and some regions of China, where up to 30% of sporadic cases of acute viral hepatitis are caused by hepatitis E virus, are considered. Continued epidemiological surveillance for viral hepatitis is essential to recognize and control possible outbreaks, but also to identify new viral hepatitis agents that may emerge as important global health

    Oxidative stress can be defined as an increase in oxidants and/or a decrease in antioxidant capacity. There is limited information about the oxidative status in subjects with hepatitis B virus infection. We aimed to evaluate the oxidative status in patients with various clinical forms of chronic hepatitis B infection. Seventy-six patients with hepatitis B virus infection, in whom 33 with chronic hepatitis, 31 inactive carriers and 12 with cirrhosis, and 16 healthy subjects were enrolled. Total antioxidant response and total peroxide level measurement, and calculation of oxidative stress index were performed in all participants. Total antioxidant response was significantly lower in cirrhotics than inactive HbsAg carriers and controls (p = 0.008 and p = 0.008, respectively). Total peroxide level and oxidative stress index was significantly higher in cirrhotic (p Total antioxidant response was comparable in chronic hepatitis B subjects, inactive HbsAg carriers and controls (both, p > 0.05/6). Total peroxide level and oxidative stress index were also comparable in inactive HBsAg carriers and controls (both, p > 0.05/6). Serum alanine amino transferase level was positively correlated with total peroxide level and oxidative stress index only in chronic hepatitis B subjects (p = 0.002, r = 0.519 and p = 0.008, r = 0.453, respectively). Oxidative stress occurs secondarily to increased total lipid peroxidation and inadequate total antioxidant response and is related to severity of the disease and replication status of virus in hepatitis B infection.

    Full Text Available Severe acute pancreatitis (SAP characterized by atrocious progression and numerous complications often leads to a high mortality rate due to hypermetabolism, systemic inflammatory response syndrome (SIRS, and multiple organs dysfunction syndrome (MODS. Studies have revealed that both early enteral nutrition (EEN and emodin are potent agents in the management of SAP. However, whether the combined strategy is rational and more effective than either one alone remains unknown. In this regard, Wistar rats were treated with emodin-assisted EEN (EAEEN through enteral nutrient tubes after induction of SAP by retrograde infusion of 5.0% sodium taurocholate into the common pancreatic duct. Serum levels of amylase, tumor necrosis factor-alpha (TNF-α, angiotensin II (AngII, maleic dialdehyde (MDA, glutamic pyruvic transaminase (ALT, glutamic oxaloacetic transaminase (AST and C-reactive protein (CRP, intestinal secretory IgA (SIgA, pancreatic and hepatic myeloperoxidase (MPO activity as well as plasma levels of D-lactate and endotoxin were measured. In addition, pathologic alterations of pancreas and liver were observed microscopically. We found that EAEEN could significantly ameliorate these parameters and prevent pancreas and liver from serious damage. In conclusion, Our results indicated that EAEEN could exert beneficial effects on experimental SAP and obviously abate the severity of secondary hepatic injury. The combined strategy was safe and more effective than either one alone in the acute stage of SAP. This study also provided an experimental base for the clinical treatment of SAP patients with EAEEN.

    Hepatitis A and E viruses are spread via the fecal-oral route. In the endemic area, restaurant and school outbreaks due to contaminated water or food have been reported. The clinical signs and symptoms in patients with typical hepatitis A and E are similar to those seen with other forms of acute viral hepatitis. Hepatitis A tends to be more severe when acquired at older ages. Hepatitis E appears to be relatively severe compared with hepatitis A. Although both hepatitis are self-limited illness, severe hepatits are rarely observed. Hepatitis A and E can be prevented by improved sanitary conditions, handwashing, heating foods appropriately. Avoidance of water and foods from endemic areas is also effective.

    Objective: To investigate the relationship between progress of disease process and changes of serum IL-12, TGF-β, CTGF and PDGF levels in patients with chronic severe hepatitis B. Methods: Serum TGF-β (with RIA) and IL-12, connective tissue growth factor (CTGF) platelet-derived growth factor (PDGF) (all with ELISA) levels were determined both before and after integrated traditional and western medicine treatment in 50 patients with chronic severe hepatitis β as well as once in 50 controls. Results: Before treatment the serum levels of IL-12 were significantly higher in patients with chronic severe hepatitis B than those in the controls (P<0.01), while after treatment, the serum levels of IL-12 were only slightly decreased and remained significantly higher than those in the controls (P<0.01). Before treatment the serum levels of TGF-β, CTGF and PDGF were all significantly higher than those in controls (P<0.01). After treatment, the levels all dropped significantly (vs before treatment, P<0.05), but still remained significantly higher than those in controls (TGF-β, P<0.05, CTGF and PDGF, P<0.01). Conclusion: Detection of changes of IL-12, TGF-β, CTGF and PDGF levels after treatment in patients with chronic severe hepatitis B provided a valuable laboratory basis for stu-ding the progress of disease process.

    The physical, clinicopathologic, and survival rates of 77 cats with severe spontaneous hepatic lipidosis are detailed in this report. Cats were subdivided into groups designated as idiopathic lipidosis if no other disease process was recognized, or secondary lipidosis if another disease process was diagnosed. Cats were also subdivided into groups designated as survivors or nonsurvivors on the basis of successful recuperation at 4 months after initial diagnosis. Differences between disease and survival groups were evaluated for significance. Overall, more female cats and middle-aged cats were affected. Presenting complaints of vomiting, anorexia, weakness, and weight loss were common. Physical assessment of most cats showed obvious hepatomegaly, jaundice, dehydration, and a weight loss > or = 25% of usual body weight. Neurobehavioral signs indicative of hepatic encephalopathy, other than ptyalism and depression, were rare. Clinicopathologic features are characterized by hyperbilirubinemia and increased activities of serum ALT, AST, and ALP, with only small if any increase in gamma GT activity. Clinical features distinguishing cats with hepatic lipidosis from those with other serious cholestatic disorders include absence of hyperglobulinemia and low gamma GT activity relative to ALP activity. Although coagulation tests were abnormal in 45% of cats tested (n = 44), few cats showed clinical bleeding tendencies. Most cats received prophylactic vitamin K1 therapy. Forty two cats received aggressive nutritional and supportive care and of these 55% survived. Cats with idiopathic disease were significantly younger, had significantly higher ALP activity and bilirubin concentration, and had a slightly better survival rate than cats with secondary lipidosis. Low PCV, hypokalemia, and an older age were significantly related to nonsurvival. Because of the variety of diets and food supplements used in case management, the influence of nutritional factors on survival could not be

    Hepatic hilar bile duct cancer was difficult to cure by surgical treatment and its prognosis was very poor. We present the case of non-curative resection of hepatic hilar bile duct cancer, controlled with external radiation. 72 years-old-female, she complained jaundice and diagnosed hepatic hilar bile duct cancer with abdominal ultrasonography. Hepatic hilar resection was performed but curative resection could not be done, because cancer was diffusely spreaded to the hepatic and duodenal ends of the bile duct. After surgery, external radiation (1.8 Gy/day; total 50.4 Gy) was performed. Three months after operation, sometimes, cholangitis was occurred but we could not detect the intrahepatic bile duct dilatation and improved with antibiotics. After seven months, she was dead for sepsis, liver abscess and biliary cirrhosis. From autopsy findings, severe hepatic hilar fibrosis around the irradiation area, stenosis of the hepatico-jejunostomy and portal vein were existed but could not detect the remnant cancer cells. External radiation was sometimes effective, especially for this case. But we should consider the side effect of fibrosis and preventive treatments such as biliary stenting or early biliary drainage.

    1991-01-01

    In an investigation of a 21-year-old epidemic of severe hepatitis, 80 serum samples were studied from two isolated Yanomami Amerindian populations of the Upper Orinoco basin in Venezuela. Of the assayed samples, 30.6% were positive for hepatitis B surface antigen (HBsAg), 53.7% were considered to reflect immunity to infection with hepatitis B virus (HBV), and only 16.2% were believed to reflect susceptibility to HBV infection; 82.5% of the samples tested positive for any marker of HBV infection. Thirty-one (39.7%) of 78 samples were also positive for antibody to delta antigen, including 91.6% of those positive for HBsAg and 20.9% of those immune to HBV. Our findings provide evidence of a high prevalence of HBV infection in this population. Furthermore, the high prevalence of antibody to delta antigen strongly suggests that coinfections with HBV or superinfections with hepatitis delta virus (HDV) in HBV carriers may be an important factor in the occurrence of an unusually high number of cases of fulminant hepatitis and of chronic liver disease. Serum samples obtained at the beginning of the outbreak 13 years earlier from 36 selected cases in the same population revealed a high rate of HBV infection (96.5%). All six HBsAg carriers from whom enough serum remained to be assayed were positive for antibody to delta antigen. Our findings indicate that the outbreak coincided with the introduction of HDV into a population with an already-high prevalence of HBV infection.

    We evaluated the clinical and virological characteristics of hepatitis A virus infection in persons concomitantly infected with hepatitis B virus (HBV) or hepatitis C virus (HCV). We enrolled 21 patients with acute hepatitis A and chronic hepatitis with no sign of liver cirrhosis, 13 patients who were positive for hepatitis B surface antigen (case B group), 8 patients who were anti-HCV positive (case C group), and 21 patients with acute hepatitis A without a preexisting liver disease (control A group). Two control groups of patients with chronic hepatitis B (control B group) or C (control C group) were also chosen. All control groups were pair-matched by age and sex with the corresponding case group. Fulminant hepatitis A was never observed, and hepatitis A had a severe course in 1 patient in the case B group and in 1 patient in the control A group. Both patients recovered. On admission, HBV DNA was detected in 1 patient in the case B group (7.7%) and in 13 patients (50%) in the control B group; HCV RNA was found in no patient in the case C group and in 16 patients (81.2%) in the control C group. Of 9 patients in the case B group who were followed up for 6 months, 3 became negative for hepatitis B surface antigen and positive for hepatitis B surface antibody, 2 remained positive for hepatitis B surface antigen and negative for HBV DNA, and 4 became positive for HBV DNA with a low viral load [corrected] Of 6 patients in the case C group who were followed up for 6 months, 3 remained negative for HCV RNA, and 3 had persistently low viral loads. Concomitant hepatitis A was always self-limited, associated with a marked inhibition of HBV and HCV genomes, and possibly had a good prognosis for the underlying chronic hepatitis.

    BACKGROUND: Millions of people worldwide suffer from hepatitis C, which can lead to severe liver disease, liver cancer, and death. Direct-acting antivirals (DAAs), e.g. sofosbuvir, are relatively new and expensive interventions for chronic hepatitis C, and preliminary results suggest that DAAs may...... eradicate hepatitis C virus (HCV) from the blood (sustained virological response). Sustained virological response (SVR) is used by investigators and regulatory agencies as a surrogate outcome for morbidity and mortality, based solely on observational evidence. However, there have been no randomised trials...... hepatitis C-related morbidity, serious adverse events, and health-related quality of life. Our secondary outcomes were all-cause mortality, ascites, variceal bleeding, hepato-renal syndrome, hepatic encephalopathy, hepatocellular carcinoma, non-serious adverse events (each reported separately), and SVR.

    Severe mental illness is associated with increased morbidity and mortality. The elevated risk of blood-borne viruses (BBVs) in people with severe mental illness is of concern, but the full extent of this problem is unclear. We aimed to determine the prevalence of and risk factors for BBVs in people with severe mental illness. In this nationwide, population-based, cross-sectional study, we estimated the point prevalence of HIV, hepatitis B (HBV), and hepatitis C (HCV) in people with severe mental illness, including the total adult (≥18 years) Swedish population. We defined severe mental illness as a clinical diagnosis of schizophrenia, schizoaffective disorder, bipolar disorder, or other psychotic illness according to the Swedish version of the International Statistical Classification of Diseases version 8, 9, or 10. We used multivariable logistic regression to determine the odds of BBVs in individuals with severe mental illness, relative to the general population, and to identify independent risk factors (age, sex, immigration status, socioeconomic status, education, and substance misuse) for BBV infection. We also did a sensitivity analysis excluding BBV diagnoses made before the introduction of the Register for Infection Disease Control (1997). Of 6 815 931 adults in Sweden, 97 797 (1·43%) individuals had a diagnosis of severe mental illness. Prevalence of BBVs was elevated in people with severe mental illness, of which 230 (0·24%) had HIV, 518 (0·53%) had HBV, and 4476 (4·58%) had HCV. After accounting for sociodemographic characteristics, the odds of HIV were 2·57 (95% CI 2·25-2·94, pmental illness than in the general population, whereas the odds of HBV were 2·29 (2·09-2·51, pmental illness and identify interventions preventing infection. Targeting of comorbid substance misuse would have particular effect on reduction of BBV prevalence in this population. Medical Research Council and Swedish Research Council.

    Full Text Available Background: High-grade blunt hepatic and/or splenic injuries (BHSI remain a great challenge for trauma surgeons. The main aim of this study was to investigate the characteristics, mortality rates, and outcomes of high-grade BHSI in motorcyclists and car occupants hospitalized for treatment of traumatic injuries in a Level I trauma center in southern Taiwan. Methods: High-grade BHSI are defined as grade III-VI blunt hepatic injuries and grade III-V blunt splenic injuries. This retrospective study reviewed the data of 101 motorcyclists and 32 car occupants who experienced a high-grade BHSI from 1 January 2011 to 31 December 2013. Two-sided Fisher’s exact or Pearson’s chi-square tests were used to compare categorical data, unpaired Student’s t-test was used to analyze normally distributed continuous data, and Mann–Whitney’s U test was used to compare non-normally distributed data. Results: In this study, the majority (76%, 101/133 of high-grade BHSI were due to motorcycle crashes. Car occupants had a significantly higher injury severity score (ISS; 26.8 ± 10.9 vs. 20.7 ± 10.4, respectively, p = 0.005 and organ injured score (OIS; 3.8 ± 1.0 vs. 3.4 ± 0.6, respectively, p = 0.033, as well as a significantly longer hospital length of stay (LOS; 21.2 days vs. 14.6 days, respectively, p = 0.038 than did motorcyclists. Car occupants with high-grade BHSI also had worse clinical presentations than their motorcyclist counterparts, including a significantly higher incidence of hypotension, hyperpnea, tube thoracostomy, blood transfusion >4 units, LOS in intensive care unit >5 days, and complications. However, there were no differences in the percentage of angiography or laparotomy performed or mortality rate between these two groups of patients. Conclusions: This study demonstrated that car occupants with high-grade BHSI were injured more severely, had a higher incidence of worse clinical presentation, had a longer hospital LOS, and had a

    Full Text Available In China, hepatitis E virus (HEV is prevalent and causes disease, but its epidemiological profile is not well understood. We used a commercial enzyme-linked immunosorbent assay to detect total antibodies to hepatitis E virus in 15,862 serum samples collected during the Third National Viral Hepatitis Prevalence Survey. The results were analyzed to calculate estimates of HEV seroprevalence and to examine the effects of some putative risk factors. The seroprevalence of HEV in the general Chinese population during the period from 2005 through 2006 was 23.46% (95% confidence interval [CI], 18.41%-28.50%. The farming population, the age group of 15-60 year olds, and those living in the Midwest or Mideast region and in Xinjiang province had the highest seroprevalence estimates. The prevalence of HEV is high in China. The seroprevalence rate of HEV shows an unbalanced distribution among areas with different geographic location and economic development levels. The characteristics of the distribution associated may be due to the route of HEV transmission (via contaminated water or animal reservoirs. Within the same region, the seroprevalence of HEV is generally increased with age.

  9. Molecular Mechanisms to Control Post-Transplantation Hepatitis B Recurrence

    Full Text Available Hepatitis B often progresses to decompensated liver cirrhosis requiring orthotopic liver transplantation (OLT. Although newer nucleos(tide analogues result in >90% viral and hepatitis activity control, severely decompensated patients still need OLT because of drug-resistant virus, acute exacerbation, or hepatocellular carcinoma. Acute hepatitis B is also an indication for OLT, because it can progress to fatal acute liver failure. After OLT, the hepatitis B recurrence rate is >80% without prevention, while >90% of transplant recipients are clinically controlled with combined hepatitis B immunoglobulin (HBIG and nucleos(tide analogue treatment. However, long-term HBIG administration is associated with several unresolved issues, including limited availability and extremely high cost; therefore, several treatment protocols with low-dose HBIG, combined with nucleos(tide analogues, have been investigated. Another approach is to induce self-producing anti-hepatitis B virus (HBV antibodies using an HBV envelope (HBs antigen vaccine. Patients who are not HBV carriers, such as those with acutely infected liver failure, are good candidates for vaccination. For chronic HBV carrier liver cirrhosis patients, a successful vaccine response can only be achieved in selected patients, such as those treated with experimentally reduced immunosuppression protocols. The present protocol for post-OLT HBV control and the future prospects of newer treatment strategies are reviewed.

    In a field study of 80 cows in 9 dairy herds, serial liver biopsies were performed over the peripartum period to determine degree of hepatic lipidosis. Cattle were separated into categories of mild, moderate, and severe hepatic lipidosis on the basis of maximal amounts of hepatic triglyceride that accumulated during this period. Number of cattle with mild, moderate, and severe hepatic lipidosis were 52, 16, and 12, respectively. Cattle with severe hepatic lipidosis had greater concentrations of hepatic triglyceride before calving and after parturition, and greater serum nonesterified fatty acid concentrations and body condition loss after parturition than cattle with mild hepatic lipidosis. Rate of disease and culling and death rate because of disease were greater in cattle with severe hepatic lipidosis. Cattle with severe hepatic lipidosis had reproductive performance equal to clinically normal cattle; however, cattle with moderate hepatic lipidosis had increased days to conception, possibly related to greater milk production.

    The aim of investigation was to study the frequency of IR in type of viral hepatitis C, correlation with the degree of hepatic lesion and liver cirrhosis. 130 patients were investigated: 20 with acute hepatitis C; 38 with chronic hepatitis C; 72 with cirrhosis: among them 10 with Stage A, 14 with Stage B and 48 with Stage C. Also we used 30 healthy people as the controls. The study demonstrates significant changes of insulin, glucose, HOMA-IR type of viral hepatitis C, correlation with the degree of hepatic lesion and liver cirrhosis. In patients with liver cirrhosis levels of HOMA-IR is higher than in patients with chronic hepatitis C. In patients with acute hepatitis C levels of HOMA-IR was normal as in the control group. The results showed that various types of chronic viral hepatitis C and stages of cirrhosis set to increase HOMA-IR versus the controls., which were the most prominent in cases of severe hepatic lesion, which indicates that insulin resistance is a frequent companion of CHC.

    Full Text Available Hepatitis B (Hepatitis B is a hepatitis B virus (HBV -based liver disease. This virus has an affinity for liver cells, it can cause both acute and chronic viral infections of varying severity. The consequences of chronic HBV infection can be cirrhosis and liver cancer. In Poland in 1989 a preventive program was implemented to reduce HBV infection. Universal vaccinations have been introduced to reduce the prevalence of Type B hepatitis B from 40.3 / 100,000 in 1989 to 7/100 in 2000. In the last 20 years in Poland there has been huge progress in the prevention and suppression of HBV infections. Decrease in the incidence of hepatitis B is mainly the result of the introduction of compulsory vaccination and improving hygiene procedures and improve sanitation aimed at aborting the pathways of the virus. However, still a large part of society is not immune on HBV infection acting potential group of the risk of infection. In addition, in the era of a growing group of followers. movements of the anti vaccine it is necessary to continue to promote knowledge of HBV and the efficacy and safety of vaccination.

The disease can be considered primary or idiopathic when its underlying cause is unknown, or secondary when there is another concomitant disease lipidosis. Cats with hepatic lipidosis have anorexia usually ranging from several days to weeks and weight loss, followed by jaundice and varying degrees of dehydration, diarrhea and vomiting episodes may occur. A worsening of the disease shows signs of hepatic encephalopathy, drooling and retroflexion of the neck. In clinical examination can be observed depression, lethargy and hepatomegaly. The definitive diagnosis of the disease can be performed by fine needle aspiration biopsy guided by ultrasound and cytology or biopsy. The treatment of hepatic lipidosis is based on stabilizing the patient by supplying water and electrolyte losses and provide adequate nutritional support. The diet is usually provided through feeding tubes for a period ranging from 4 to 6 weeks may occur depending on the patient's condition. The prognosis for cats with hepatic lipidosis is favored in cases of identification followed by intensive treatment of underlying causes and for patients receiving therapy necessary in cases of idiopathic hepatic lipidosis.

    Erica Villa

    Full Text Available Chronic hepatitis C is the main cause of death in patients with end-stage liver disease. Prognosis depends on the increase of fibrosis, whose progression is twice as rapid in men as in women. Aim of the study was to evaluate the effects of reproductive stage on fibrosis severity in women and to compare these findings with age-matched men.A retrospective study of 710 consecutive patients with biopsy-proven chronic hepatitis C was conducted, using data from a clinical database of two tertiary Italian care centers. Four age-matched groups of men served as controls. Data about demographics, biochemistry, liver biopsy and ultrasonography were analyzed. Contributing factors were assessed by multivariate logistic regression analysis.Liver fibrosis was more advanced in the early menopausal than in the fully reproductive (P<0.0001 or premenopausal (P = 0.042 group. Late menopausal women had higher liver fibrosis compared with the other groups (fully reproductive, P<0.0001; premenopausal, P = <0.0001; early menopausal, P = 0.052. Multivariate analyses showed that male sex was independently associated with more severe fibrosis in the groups corresponding to premenopausal (P = 0.048 and early menopausal (P = 0.004 but not late menopausal pairs. In women, estradiol/testosterone ratio decreased markedly in early (vs. reproductive age: P = 0.002 and vs. premenopausal: P<0.0001 and late menopause (vs. reproductive age: P = 0.001; vs. premenopausal: P<0.0001. In men age-matched with menopausal women, estradiol/testosterone ratio instead increased (reproductive age group vs. early: P = 0.002 and vs. late M: P = 0.001.The severity of fibrosis in women worsens in parallel with increasing estrogen deprivation and estradiol/testosterone ratio decrease. Our data provide evidence why fibrosis progression is discontinuous in women and more linear and severe in men, in whom aging-associated estradiol/testosterone ratio increase occurs too late to noticeably influence the

    Full Text Available Aim: To evaluate the local control of hepatic metastasis with radiofrequency ablation treatment. Materials and Methods: We did a retrospective analysis in 40 patients treated with radiofrequency ablation for hepatic metastasis. The tumors ablated included up to two metastatic liver lesions, with primaries in breast, gastrointestinal tract, cervix, etc. Radiofrequency ablation was performed under general anesthesia in all cases, using ultrasound guidance. Radionics Cool-Tip RF System was used to deliver the treatment. Results: The median age of patients treated was 49 years. There were 13 female and 27 male patients. The median tumor size ablated was 1.5 cm (0.75-4.0 cm. A total of 52 radiofrequency ablation cycles were delivered. Successful ablation was achieved in all patients with hepatic metastasis less than 3 cm in size. Pain was the most common complication seen (75%. One patients developed skin burns. At 2-year follow-up 7.5% of patients had locally recurrent disease. Conclusions: Radiofrequency ablation is a minimally invasive treatment modality. It can be useful in a select group of patients with solitary liver metastasis of less than 3 cm size.

    The purpose of this study was to evaluate change in the proton MR spectroscopic ( 1 H-MRS) features of the liver according to changes in the severity of the chronic hepatitis spectrum (normal-chronic hepatitis-liver cirrhosis), and to determine the possibility of replacing liver biopsy by 1 H-MRS. Sixty profiles of 1 H-MRS features from 15 normal volunteers, 30 cases of chronic hepatitis, and 15 of liver cirrhosis were evaluated. All cases of chronic hepatitis and liver cirrhosis were confirmed by biopsy, and histopathologic disease severity was categorized according to Ludwig's classification. Using the STEAM (STimulated Echo-Aquisition Mode) sequence, 1 H-MRS was performed. The ratios of peak areas of (glutamate + glutamine)/lipid, phosphomonoesters/lipid, (glycogen + glucose)/lipid, and (3.9-4.1 ppm unknown peak)/lipid and their mean and standard deviation were calculated in normal, chronic hepatitis stages I and II, and early and late liver cirrhosis groups and the results were compared between these groups. One-way variable analysis was applied to the statistics. Mean and standard deviation of phosphomonoesters/lipid in the normal, chronic hepatitis grades I and II, and early and late liver cirrhosis groups were 0.0146±0.0090, 0.0222±0.0170, 0.0341±0.0276, 0.0698±0.0360, and 0.0881±0.0276, respectively, and (glycogen + glucose)/lipid were 0.0403±0.0267, 0.0922±0.0377, 0.1230±0.0364, 0.1853±0.0667, 0.2325±0.1071, respectively. These results implied that the ratio of the above metabolites to lipid content increased according to increasing disease severity (p less than 0.05). For (glutamate + glutamine)/lipid however, the ratios for each group were 0.0204±0.0067, 0.0117±0.0078, 0.0409±0.0167, 0.0212±0.0103, and 0.0693±0.0371, respectively, and there was no correlation with disease severity. In the chronic hepatitis grades I and II, and early and late liver cirrhosis groups, the ratios for (3.9-4.1 ppm unknown peak)/lipid were 0.0302±0.0087, 0

    Hepatic veno-occlusive disease (VOD), also known as sinusoidal obstruction syndrome, is a potentially life-threatening complication of chemotherapeutic conditioning used in preparation for hematopoietic stem-cell transplantation (SCT). VOD may occur in up to 62% of patients undergoing SCT, with onset generally within the first month after SCT. In severe cases, 100-day mortality is in excess of 80%. Current management consists of best supportive care, with no agents to date approved for treatment in the USA or the EU. Defibrotide, a polydisperse oligonucleotide, has been shown in phase II and III trials to improve complete response and survival in patients undergoing SCT with severe VOD. This article reviews our current understanding of VOD, and examines recent clinical findings on defibrotide for the treatment and prophylaxis of VOD.

    AIMS: The hepatic venous pressure gradient is a major prognostic factor in portal hypertension but its measurement is complex and requires invasive angiography. This study investigated the relationship between the hepatic venous pressure gradient and a number of Doppler measurements, including the arterial acceleration index. METHOD: We measured the hepatic venous pressure gradient in 50 fasting patients at hepatic venography. Immediately afterwards, a duplex sonographic examination of the liver was performed at which multiple measurements and indices of the venous and arterial hepatic vasculature were made. RESULTS: Hepatic arterial acceleration was correlated directly with the hepatic venous pressure gradient (r = 0.83, P -2 provided a positive predictive value of 95%, a sensitivity of 65% and a specificity of 95% for detecting patients with severe portal hypertension (hepatic venous pressure gradient > 12 mmHg). A correlation between the hepatic venous pressure gradient and the congestion index of the portal vein velocity (r = 0.45,P = 0.01) and portal vein velocity (r = 0.40,P = 0.044), was also noted. CONCLUSION: Measuring the hepatic arterial acceleration index may help in the non-invasive evaluation of portal hypertension. Tasu, J.-P. et al. (2002)

    Today, viral hepatitis has become a silent epidemic worldwide. It is the major cause of liver cirrhosis and liver carcinoma. In a dental office, infections can be expedited through several routes, including direct or indirect contact with blood, oral fluids, droplet splatter, aerosols, etc. The aim of the present review is to increase the awareness among dental practitioners, so as to reduce the burden of hepatitis in their community. Electronic databases like PubMed, Medline, ProQuest, etc. were searched using the keywords hepatitis, dentist, liver disease, and infection control. Manual search of various journals and books was also carried out. Only highly relevant articles from English literature were considered for the present review. The results revealed that the dentists were among the high-risk groups for hepatitis, and they have little information on the factors associated with adherence to hepatitis B vaccination. A dentist can play a major role in the prevention of hepatitis by considering each and every patient as a potential carrier of hepatitis. Proper infection control, sterilization, and prophylactic vaccination protocols should be followed in order to reduce the risk of hepatitis.

    Discerning drug hepatotoxicity from viral hepatitis flares remains an ongoing problem unique to patients coinfected with HIV and hepatitis B (HBV). We present three such coinfected patients who have been on two anti-HBV agents, lamivudine and tenofovir disoproxil fumarate simultaneously, as part of highly active antiretroviral therapy (HAART). All three developed significant aminotransferase elevations 6-12 weeks after initiation of HAART despite being on two active HBV drugs. Two of the three patients were initially thought to have drug-related hepatotoxicity from HIV medications. It seems more likely that all three patients demonstrated hepatitis B reactivation of differing severity as the result of varying degrees of immune recovery. Distinguishing clearly between drug-related hepatotoxicity and hepatitis reactivation may be difficult but is important as their clinical management differs.

    Full Text Available Epstein-Barr virus, a member of the Herpesviridae family, is responsible for the infectious mononucleosis clinical syndrome, which mainly includes the pharyngitis, fever, and lymphadenopathy triad after incubation for 30-50 days. The liver is involved in 80-90% of patients in a self-limiting transient manner, with jaundice being much more uncommon (5%. From a hematological standpoint it may manifest aplastic anemia, neutropenia, and thrombocytopenia. We report a case of infectious mononucleosis that included severe acute hepatitis and was associated with severe hemolytic anemia secondary to cold agglutinins. After exclusion of other etiologies, and given the clinical suspicion of the above association, which was later confirmed by lab tests, empiric therapy was initiated with antiviral agents (aciclovir + valganciclovir and corticoids, which resulted in a progressive clinical improvement until complete remission. Therefore, we believe that this case report will reinforce the clinical evidence in support of the above combined therapy for serious infectious mononucleosis as a step prior to liver transplantation.

    Excess alcohol consumption can worsen the course and outcome of chronic hepatitis C. It is important to distinguish between alcohol abuse, which must be treated on its own merits, and the effect of alcohol use on progression, severity, and treatment of hepatitis C. Most studies on the effects of alcohol on hepatitis C have focused on patients, with high levels of daily alcohol intake. Indeed, the adverse effects of light and moderate amounts of alcohol intake on hepatitis C virus (HCV) infect...

    Full Text Available Introduction: Viral hepatitis is among the main problems that affect public health globally. The knowledge of the clinical and epidemiological situation of hepatitis B and hepatitis C is necessary for the establishment of prevention and control strategies together with individuals and communities in vulnerable situations. Objective: To investigate the clinical and epidemiological aspects of the population affected by hepatitis B and hepatitis C from 2007 to 2014, in Fortaleza, Ceara, Brazil. Methodology: Descriptive, retrospective study involving data from the Notifiable Diseases Information System, with analysis of gender, age, race, illicit drug use, sex partnerships, tattoo/piercing, transfusion, dialysis and transplantation. Chi-squared tests were used for statistical analysis of the variables. Results: It was reported 779 cases of hepatitis B and 756 of hepatitis C. Regarding the HBV, 69.7% were male, 77.5% of brown color, and a median age of 36 years. Regarding risk factors, there was highlight for sexual practice and number of sex partners (p = 0.001, blood transfusion (p = 0.011 and use of tattoo/piercing (p = 0.011. As for HCV, 57.7% were male and the mean age was 46 years. As for risk factors, the injecting drug use (p = 0.001, the presence of three or more partners (p = 0.001 and the use of tattoo/piercing (p = 0.021 stood out. Regardless of gender, age or race and drug use, transfusions and age over 40 years increased the risk for hepatitis. There were still high percentages of missing data in several variables. Conclusion: This study contributes to alert the Brazilian health authorities on the importance of these infections and the need to expand and strengthen current health policies, and allows reflection on control strategies for hepatitis. Keywords: Hepatitis B; Hepatitis C; Risk factors.

    Hepatitis A is among the diseases that can be prevented with vaccination in our time. Acute hepatitis A progresses more severely in individuals with a liver disease. Therefore, patients with a chronic liver disease (because of hepatitis B or hepatitis C) are advised vaccination with the hepatitis A vaccine. This study is aimed to determine the seroprevalence of hepatitis A virus (HAV) antibodies in patients infected with hepatitis C virus or hepatitis B virus in Konya province of Turkey. A total of 537 patients who had chronic viral hepatitis between January 2011 and December 2014 were included in the study. Serum samples were collected from each patient and tested for anti-HAV using the chemiluminescent microparticle immunoassay. The overall seroprevalence of total anti-HAV IgG was 94.2%. The overall prevalence of anti-HAV IgG in patients with chronic hepatitis B virus and hepatitis C virus infection was 97.5 and 93.6%, respectively. Anti-HAV IgG positivity was 97.4% in cirrhotic patients and 93.9% in noncirrhotic individuals. At the end of the study, being older than 40 years and living in a rural area were found to be independent risk factors for anti-HAV IgG seropositivity. In conclusion, we recommend that patients younger than 40 years and/or those living in cities and having a chronic liver disease should be vaccinated with the hepatitis A vaccine.

    Neonatal hepatitis with acute liver failure due to varied etiology including various infections is reported in the past. Scrub typhus as a cause of neonatal hepatitis has rarely been reported in literature. A high index of clinical suspicion is required for early diagnosis and timely treatment. Severity and prognosis of the disease varies widely because several different strains of Orientia tsutsugamushi exist with different virulence. Delayed diagnosis can result in complication and significant morbidity and mortality. Here, we report three cases of neonatal hepatitis with acute liver failure caused by scrub typhus to increase awareness.

    Full Text Available BACKGROUND Regular monitoring of serum iron parameters is helpful for assessing the severity of alcoholic liver disease. Assessment of serum iron parameters are used for screening hereditary haemochromatosis in chronic liver disease. Serum iron parameters in chronic liver disease have not been clearly described in most of the studies. The aim of this study was to assess the serum iron, Total Iron Binding Capacity (TIBC, transferrin saturation and ferritin levels in common chronic liver disease like alcoholic cirrhosis, cryptogenic cirrhosis, chronic hepatitis C and chronic hepatitis B. MATERIALS AND METHODS 110 consecutive patients with chronic liver disease admitted to the Gastroenterology Department, Government Medical College, Kozhikode were selected for the study. The categories of chronic liver disease included in our study were alcoholic cirrhosis (Group I, n = 40, cryptogenic cirrhosis (Group II, n = 30, chronic hepatitis C (Group III, n = 20 and chronic hepatitis B (Group IV, n = 20. Serum iron, ferritin, total iron binding capacity and transferrin saturation were estimated in the fasting sample. Statistical Analysis- Analysis was performed using nonparametric Kruskal-Wallis and Bonferroni test to assess statistical significance of difference of continuous variables among and between groups, respectively. The results were considered statistically significant at the level of p <0.05. RESULTS The serum iron level was normal and total iron binding capacity was low in all the four groups of chronic liver disease. Serum ferritin and transferrin saturation were significantly higher in alcoholic cirrhosis in comparison with cryptogenic cirrhosis and chronic hepatitis B, but was not statistically significant in comparison with chronic hepatitis C. CONCLUSION We observed irregularities in iron status in patients with alcoholic cirrhosis, cryptogenic cirrhosis, chronic hepatitis C and chronic hepatitis B.

    Full Text Available Background. Synthetic cathinones (SCs, also known as “bath salts,” are β-ketone amphetamine compounds derived from cathinone, a psychoactive substance found in Catha edulis. Mephedrone is the most representative SC. Slamming is the term used for the intravenous injection of these substances in the context of chemsex parties, in order to enhance sex experiences. Using IV mephedrone may lead to diverse medical and psychiatric complications like psychosis, aggressive behavior, and suicide ideation. Case. We report the case of a 25-year-old man admitted into a psychiatric unit, presenting with psychotic symptoms after slamming mephedrone almost every weekend for the last 4 months. He presents paranoid delusions, intense anxiety, and visual and kinesthetic hallucinations. He also shows intense craving, compulsive drug use, general malaise, and weakness. After four weeks of admission and antipsychotic treatment, delusions completely disappear. The patient is reinfected with hepatitis C. Discussion. Psychiatric and medical conditions related to chemsex and slamming have been reported in several European cities, but not in Spain. Psychotic symptoms have been associated with mephedrone and other SCs’ consumption, with the IV route being prone to produce more severe symptomatology and addictive conducts. In the case we report, paranoid psychosis, addiction, and medical complications are described.

    Anorexia nervosa (AN) has the highest mortality rate of all psychiatric illnesses due to the widespread organ dysfunction caused by the underlying severe malnutrition. Starvation causes hepatocyte injury and death leading to a rise in aminotransferases. Malnutrition-induced hepatitis is common among individuals with AN especially as body mass index decreases. Acute liver failure associated with coagulopathy and encephalopathy can rarely occur. Liver enzymes may also less commonly increase as part of the refeeding process due to hepatic steatosis and can be distinguished from starvation hepatitis by the finding of a fatty liver on ultrasonography. Individuals with AN and starvation-induced hepatitis are at increased risk of hypoglycemia due to depleted glycogen stores and impaired gluconeogenesis. Gastroenterology and hepatology consultations are often requested when patients with AN and signs of hepatitis are hospitalized. It should be noted that additional laboratory testing, imaging, or liver biopsy all have low diagnostic yield, are costly, and potentially invasive, therefore, not generally recommended for diagnostic purposes. While the hepatitis of AN can reach severe levels, a supervised increase in caloric intake and a return to a healthy body weight often quickly lead to normalization of elevated aminotransferases caused by starvation.

    Hepatic apparent diffusion coefficient (ADC) values and ADC-related indices were correlated with the Mayo risk score for primary biliary cirrhosis (MRSPBC) and METAVIR scores of liver specimens to determine the clinical and pathological significance of diffusion-weighted magnetic resonance imaging (DWMRI). Thirty-two patients with biliary atresia (BA; mean age 461 days, range 11-4616 days) received magnetic resonance examinations from March 2009 to August 2013. A free-breathing DWMRI sequence was performed with the single-shot echo-planar imaging technique with b = 0 and 500 s/mm 2 in all 32 BA patients and 24 controls. We used the ordinal logistic regression test and Spearman rank correlation test to analyse the relationships between the MRSPBC and METAVIR fibrosis scores and right liver-to-psoas ADC ratios (LTPARs). BA patients had significantly lower LTPARs in both hepatic lobes than controls (p < 0.01). Right LTPARs, showing moderate intraobserver agreement (intraclass correlation coefficient = 0.736) and interobserver reliability (intraclass correlation coefficient = 0.659), were negatively correlated with MRSPBC and METAVIR fibrosis scores (R 2 = 0.398, p = 0.024 and R 2 = 0.628, p < 0.001, respectively). Right LTPARs may be used for long-term follow-up of cirrhosis severity in BA patients. (orig.)

    2014-01-01

    Non-alcoholic fatty liver disease (NAFLD) describes a range of conditions caused by fat deposition within liver cells. Liver fat content reflects the equilibrium between several metabolic pathways involved in triglyceride synthesis and disposal, such as lipolysis in adipose tissue and de novo lipogenesis, triglyceride esterification, fatty acid oxidation and very-low-density lipoprotein synthesis/secretion in hepatic tissue. In particular, it has been demonstrated that hepatic de novo lipogenesis plays a significant role in NAFLD pathogenesis. It is widely known that the fatty acid composition of the diet influences hepatic lipogenesis along with other metabolic pathways. Therefore, dietary fat may not only be involved in the pathogenesis of hepatic steatosis, but may also prevent and/or reverse hepatic fat accumulation. In this review, major data from the literature about the role of some dietary fats as a potential cause of hepatic fat accumulation or as a potential treatment for NAFLD are described. Moreover, biochemical mechanisms responsible for an increase or decrease in hepatic lipid content are critically analyzed. It is noteworthy that both quantitative and qualitative aspects of dietary fat influence triglyceride deposition in the liver. A high-fat diet or the dietary administration of conjugated linoleic acids induced hepatic steatosis. In contrast, supplementation of the diet with krill oil or pine nut oil helped in the prevention and/or in the treatment of steatotic liver. Quite interesting is the “case” of olive oil, since several studies have often provided different and⁄or conflicting results in animal models. PMID:24587652

    Early monitoring of non-alcoholic fatty liver disease (NAFLD) progression in obese patients is important to avoid the development of complications associated with fatty infiltration. of this study was to investigate the relationship between the degrees of fatty infiltration and reduced vascular compliance in NAFLD patients in the three main hepatic vessels. Two hundred and fourty subjects were enrolled in the study. They were divided into 4 groups: 60 controls, 60 grade 1 NAFLD patients, 60 grade 2 NAFLD patients and 60 grade 3 NAFLD patients. After US confirmation of the presence and grade of NAFLD, the peak and mean portal vein velocity (PPVV and MPVV, respectively), the hepatic artery resistance index (HARI), and the phasicity of the hepatic vein were measured. The PPVV was 19.6 +/- 2.4 cm/sec in patients with grade 1 fatty liver, 17.6 +/- 1.2 cm/sec in grade 2 and 15.4 +/- 1.1 cm/sec in grade 3. The MPVV was 16.6 +/- 2.4 cm/sec in patients with grade 1 fatty liver, 16.6 +/- 2.9 cm/sec in grade 2 and 12.7 +/- 0.7 cm/sec in grade 3. The HARI was 0.75 in patients with grade 1 fatty liver, 0.68 in grade 2 and 0.64 in grade 3. There was an inverse relationship between PPVV, MPVV and HARI and different grades of fatty liver in patients (p = 0.001 for PPVV (Figure 7) and HARI, p = 0.006 for MPVV. The values of the investigated liver blood flow parameters were inversely correlated with the fatty infiltration grading. Fatty infiltration can severely influence hepatic blood flow, pointing attention to the importance of early diagnosis and the need for hepatic vessel flow abnormalities characterization in the NAFLD population.

    This study was prepared to address two objectives: (a) to determine whether progressively higher total doses of hepatic irradiation can prolong survival in a selected population of patients with liver metastases and (b) to refine existing concepts of liver tolerance for fractionated external radiation. One hundred seventy-three analyzable patients with computed tomography measurable liver metastases from primary cancers of the gastrointestinal tract were entered on a dose escalating protocol of twice daily hepatic irradiation employing fractions of 1.5 Gy separated by 4 hr or longer. Sequential groups of patients received 27 Gy, 30 Gy, and 33 Gy to the entire liver and were monitored for acute and late toxicities, survival, and cause of death. Dose escalation was implemented following survival of 10 patients at each dose level for a period of 6 months or longer without clinical or biochemical evidence of radiation hepatitis. The use of progressively larger total doses of radiation did not prolong median survival or decrease the frequency with which liver metastases were the cause of death. None of 122 patients entered at the 27 Gy and 30 Gy dose levels revealed clinical or biochemical evidence of radiation induced liver injury. Five of 51 patients entered at the 33 Gy level revealed clinical or biochemical evidence of late liver injury with an actuarial risk of severe (Grade 3) radiation hepatitis of 10.0% at 6 months, resulting in closure of the study to patient entry. The study design could not credibly establish a safe dose for hepatic irradiation, however, it did succeed in determining that 33 Gy in fractions of 1.5 Gy is unsafe, carrying a substantial risk of delayed radiation injury. The absence of apparent late liver injury at the 27 Gy and 30 Gy dose levels suggests that a prior clinical trial of adjuvant hepatic irradiation in patients with resected colon cancer may have employed an insufficient radiation dose (21 Gy) to fully test the question

    The human microfibrillar-associated protein 4 (MFAP4) is located to extracellular matrix fibers and plays a role in disease-related tissue remodeling. Previously, we identified MFAP4 as a serum biomarker candidate for hepatic fibrosis and cirrhosis in hepatitis C patients. The aim of the present study was to elucidate the potential of MFAP4 as biomarker for hepatic fibrosis with a focus on the differentiation of no to moderate (F0-F2) and severe fibrosis stages and cirrhosis (F3 and F4, Desmet-Scheuer scoring system). MFAP4 levels were measured using an AlphaLISA immunoassay in a retrospective study including n = 542 hepatitis C patients. We applied a univariate logistic regression model based on MFAP4 serum levels and furthermore derived a multivariate model including also age and gender. Youden-optimal cutoffs for binary classification were determined for both models without restrictions and considering a lower limit of 80 % sensitivity (correct classification of F3 and F4), respectively. To assess the generalization error, leave-one-out cross validation (LOOCV) was performed. MFAP4 levels were shown to differ between no to moderate fibrosis stages F0-F2 and severe stages (F3 and F4) with high statistical significance (t test on log scale, p value <2.2·10(-16)). In the LOOCV, the univariate classification resulted in 85.8 % sensitivity and 54.9 % specificity while the multivariate model yielded 81.3 % sensitivity and 61.5 % specificity (restricted approaches). We confirmed the applicability of MFAP4 as a novel serum biomarker for assessment of hepatic fibrosis and identification of high-risk patients with severe fibrosis stages in hepatitis C. The combination of MFAP4 with existing tests might lead to a more accurate non-invasive diagnosis of hepatic fibrosis and allow a cost-effective disease management in the era of new direct acting antivirals.

    High-grade blunt hepatic and/or splenic injuries (BHSI) remain a great challenge for trauma surgeons. The main aim of this study was to investigate the characteristics, mortality rates, and outcomes of high-grade BHSI in motorcyclists and car occupants hospitalized for treatment of traumatic injuries in a Level I trauma center in southern Taiwan. High-grade BHSI are defined as grade III-VI blunt hepatic injuries and grade III-V blunt splenic injuries. This retrospective study reviewed the data of 101 motorcyclists and 32 car occupants who experienced a high-grade BHSI from 1 January 2011 to 31 December 2013. Two-sided Fisher's exact or Pearson's chi-square tests were used to compare categorical data, unpaired Student's t-test was used to analyze normally distributed continuous data, and Mann-Whitney's U test was used to compare non-normally distributed data. In this study, the majority (76%, 101/133) of high-grade BHSI were due to motorcycle crashes. Car occupants had a significantly higher injury severity score (ISS; 26.8 ± 10.9 vs. 20.7 ± 10.4, respectively, p = 0.005) and organ injured score (OIS; 3.8 ± 1.0 vs. 3.4 ± 0.6, respectively, p = 0.033), as well as a significantly longer hospital length of stay (LOS; 21.2 days vs. 14.6 days, respectively, p = 0.038) than did motorcyclists. Car occupants with high-grade BHSI also had worse clinical presentations than their motorcyclist counterparts, including a significantly higher incidence of hypotension, hyperpnea, tube thoracostomy, blood transfusion >4 units, LOS in intensive care unit >5 days, and complications. However, there were no differences in the percentage of angiography or laparotomy performed or mortality rate between these two groups of patients. This study demonstrated that car occupants with high-grade BHSI were injured more severely, had a higher incidence of worse clinical presentation, had a longer hospital LOS, and had a higher incidence of complications than motorcyclists.

    Pheochromocytomas are uncommon tumors that represent a potentially curable cause of hypertension. They are usually located in the adrenal glands, but 10% arise from extra-adrenal sites, located along the paravertebral sympathetic chains. We report a case of primary hepatic pheochromocytoma responsible for a severe hypertension in a 24-year-old man. Echotomography showed a lightly heterogeneous mass located in the segment 8 of the liver. Iodine 131 -metaiodobenzylguanidine scintigraphy showed a large hepatic concentration of the tracer and no other localization. This tumor appeared highly vascularized on enhanced CT scan and on aortic angiography. Magnetic resonance imaging revealed a hepatic tumor with a high signal intensity on T2-weighted images and with a signal isointense to the liver on T1-weighted images. The hepatic venous sampling contained the highest catecholamine level, whereas the adrenal venous samping was normal. After surgical resection of the hepatic tumor, the tension level and catecholamines plasmatic level normalized. No recurrent symptoms appeared during a 3-year follow-up. (orig.)

    Full Text Available Objective: To study the hepatic dysfunction in children with dengue infection and find out its correlation with the severity of dengue fever. Methods: Seventy-two cases of dengue fever as per the World Health Organization aged from 2 months to 18 years of age guidelines serologically confirmed by dengue NS1 antigen detection or dengue IgM capture ELISA were studied for their hepatic dysfunction after excluding malaria, enteric fever, hepatitis A and hepatitis B. The duration of the study was from April 2013 to March 2014. Results: These 72 cases were grouped into severe dengue, dengue fever with warning sign and dengue fever without warning sign as per the World Health Organization guidelines. The spectrums of hepatic manifestations included hepatomegaly (66%, hepatic tenderness (44%, jaundice (9.72%, raised levels of aspartate transaminase (86%, alanine transaminase (90%, alkaline phosphatase (39%, prolonged prothrombin time (11% and reduced levels of serum albumin (66%. Conclusions: Tender hepatomegaly and elevated liver enzymes were seen more frequently in severe dengue. There was significant derangement between liver function and tender hepatomegaly. Altered liver function may be evident even in the absence of hepatomegaly.

    Delayed diagnosis of patients with severe liver injuries is associated with an adverse outcome. As computed tomographic (CT) scan is not always available in the management of blunt abdominal trauma worldwide, the present study was undertaken to determine the accuracy of selected haematological markers in predicting the presence of hepatic injury and its severity after blunt abdominal trauma. A retrospective review of all patients with blunt abdominal trauma presented to our institution over a 3-year period was performed. Patients were excluded if they suffered penetrating injuries, died in the emergency department or if the required blood tests were not performed within 24h of the accident. The grading of the hepatic injury was verified using CT scans or surgical findings. Ninety-nine patients with blunt abdominal trauma had the required blood tests performed and were included in the study. The median injury severity score was 24 (range 4-75). Fifty-five patients had hepatic injuries, of which 47.3% were minor (Grades I and II) while 52.7% had major hepatic injuries (Grades III-V). There were no patients with Grade VI injuries. A raised ALT was strongly associated with presence of hepatic injuries (OR, 109.8; 95% CI, 25.81-466.9). This relation was also seen in patients with raised AST>2 times (OR, 21.33; 95% CI, 7.27-62.65). This difference was not seen in both bilirubin and ALP. ALT>2 times normal was associated with major hepatic injuries (OR, 7.15; 95% CI, 1.38-37.14; p=0.012) while patients with simultaneous raised AST>2 times and ALT>2 times had a stronger association for major hepatic injuries (OR, 8.44; 95% CI, 1.64-43.47). Abnormal transaminases levels are associated with hepatic injuries after blunt abdominal trauma. Patients with ALT and AST>2 times normal should be assumed to possess major hepatic trauma and managed accordingly. Patients with normal ALT, AST and LDH are unlikely to have major liver injuries.

    Patients with chronic hepatitis C frequently report tiredness, easy fatigability, and depression. The aim of this study is to determine whether hepatitis C virus (HCV) replication could be found in brain tissue in patients with hepatitis C and depression. We report two patients with recurrent hepatitis C after liver transplantation who also developed severe depression. One patient died of multiorgan failure and the other, septicemia caused by Staphylococcus aureussis. Both patients had evidence of severe hepatitis C recurrence with features of cholestatic fibrosing hepatitis. We were able to study samples of their central nervous system obtained at autopsy for evidence of HCV replication. The presence of HCV RNA-negative strand, which is the viral replicative form, was determined by strand-specific Tth-based reverse-transcriptase polymerase chain reaction. Viral sequences were compared by means of single-strand conformation polymorphism and direct sequencing. HCV RNA-negative strands were found in subcortical white matter from one patient and cerebral cortex from the other patient. HCV RNA-negative strands amplified from brain tissue differed by several nucleotide substitutions from serum consensus sequences in the 5' untranslated region. These findings support the concept of HCV neuroinvasion, and we speculate that it may provide a biological substrate to neuropsychiatric disorders observed in patients with chronic hepatitis C. The exact lineage of cells permissive for HCV replication and the possible interaction between viral replication and cerebral function that may lead to depression remain to be elucidated.

    Hepatic encephalopathy is a spectrum of neurocognitive manifestations often seen in patients with liver injury or rarely in patients with portosystemic shunting without liver injury. It can be divided into minimal (covert) hepatic encephalopathy and overt hepatic encephalopathy, depending on the severity. Patients with hepatic encephalopathy have compromised clinical outcomes, decreased quality of life, and increased healthcare utilization, often resulting in a heavy financial and personal burden on caregivers. The diagnosis remains largely clinical, with the exclusion of possible other causes for the altered mental status. Current treatment strategies include nonabsorbable disaccharides and antibiotics. This review will focus on the diagnosis, management and clinical impact of hepatic encephalopathy. PMID:27377741

  11. Contradictory Immune Response in Post Liver Transplantation Hepatitis B and C

    2014-01-01

    Full Text Available Hepatitis B and C often progress to decompensated liver cirrhosis requiring orthotopic liver transplantation (OLT. After OLT, hepatitis B recurrence is clinically controlled with a combination of hepatitis B immunoglobulin (HBIG and nucleos(tide analogues. Another approach is to induce self-producing anti-hepatitis B virus (HBV antibodies using a HBV envelope antigen vaccine. Patients who had not been HBV carriers such as acutely infected liver failure or who received liver from HBV self-limited donor are good candidate. For chronic HBV carrier patients, a successful response can only be achieved in selected patients such as those treated with experimentally reduced immunosuppression protocols or received an anti-HBV adaptive memory carrying donor liver. Hepatitis C virus (HCV reinfects transplanted livers at a rate of >90%. HCV reinfected patients show different severities of hepatitis, from mild and slowly progressing to severe and rapidly progressing, possibly resulting from different adaptive immune responses. More than half the patients require interferon treatment, although the success rate is low and carries risks for leukocytopenia and rejection. Managing the immune response has an important role in controlling recurrent hepatitis C. This study aimed to review the adaptive immune response in post-OLT hepatitis B and C.

    Purpose: Treatment of patients with unresectable liver metastases is challenging. Regional therapies to the liver have been developed that maximize treatment of the localized disease process without systemic toxic adverse effects. We discuss the procedural aspects of liver chemosaturation with percutaneous hepatic perfusion (CS-PHP). Methods: We present as an illustration of this technique a case report of the treatment of unresectable metastatic leiomyosarcoma of the liver. Results: A randomized phase III trial for unresectable liver metastases from melanoma was recently completed comparing CS-PHP with melphalan vs. best alternative care (BAC). When compared with BAC, CS-PHP was associated with a significant improvement in hepatic progression-free survival (8.0 months CS-PHP vs. 1.6 months BAC, p < 0.0001) and overall progression-free survival (6.7 months CS-PHP vs. 1.6 months BAC, p < 0.0001), respectively. On the basis of these results, and given our experience as one of the treating institutions for this phase III trial, we appealed for compassionate use of CS-PHP in a patient with isolated bilobar unresectable hepatic metastases from leiomyosarcoma. Four target lesions were identified and monitored to assess treatment response. A total of 4 CS-PHP procedures were performed, with a 25 % reduction in size of the largest lesion observed and 16 month hepatic progression-free survival. Toxicity was mild (neutropenia) and manageable on an outpatient basis. Conclusion: CS-PHP offers several advantages for unresectable hepatic sarcoma metastases. CS-PHP is minimally invasive and repeatable, and it has a predictable and manageable systemic toxicity profile. For appropriately selected patients, CS-PHP can delay tumor progression and could potentially improve survival.

    A case of hepatic encephalopathy induced by thorotrast injected as a contrast 40 years before was reported. The patient was a 64-year-old man with severe liver dysfunction, and had psychic and neurological symptoms, and hyperammonemia. There was a relationship between ammonium concentration in blood and psychic and neurological symptoms. Electroencephalogram showed three phases waves peculiar to hepatic coma intermittently. Thorotrast in the liver was detected by radiological methods and in vivo measurement of the radioactivity. From the above-mentioned result, this disease was diagnosed as hepatic encephalopathy induced by long-term sedimentation of thorotrast without complication of malignant tumors. Because of the concurrent presence of cerebral infarction, the diagnosis was difficult to make.

    The liver is frequently involved by amyloidosis, but hyperbilirubinemia and liver failure are uncommon features. A mild elevation of the serum alkaline phosphatase value and, less frequently, hepatomegaly are the most common findings. Usually the patients have no symptoms related with the liver involvement; the clinical manifestation and the long term prognosis depends on the renal and cardiac disease. We report an unusual clinical presentation of primary amyloidosis in a previously asymptomatic 65 years old woman who was admitted to the hospital because of ictericia and ascitis mimicking a drug induced acute hepatic failure.

    Background: Hepatitis B and C related chronic liver diseases have led to development of a serious threat to the people of South Asia. The main aim of this study was to evaluate the correlation of magnitude of arterial deoxygention to the severity of liver disease. Methods: It was a hospital based cross sectional descriptive study, carried out in the Medical Department of Khyber Teaching Hospital Peshawar. All in all 115 patients were assessed for the severity of the liver diseases and were correlated with arterial deoxygenation using linear regression models. Results: Male to female ratio was 1.5:1. Males infected with hepatitis B, hepatitis C and both were 9, 60 and 1, while females suffered from hepatitis B, Hepatitis C and both were 2, 42 and 1 respectively. The linear relationship between A-a DO2 with severity of liver disease showed positive correlation while PO2 showed negative correlation with severity of liver disease. Conclusion: There was a positive correlation between A-a DO2 and severity of liver diseases while PO2 and severity of liver diseases showed negative correlation. (author)

    AIMS: The hepatic venous pressure gradient is a major prognostic factor in portal hypertension but its measurement is complex and requires invasive angiography. This study investigated the relationship between the hepatic venous pressure gradient and a number of Doppler measurements, including the arterial acceleration index. METHOD: We measured the hepatic venous pressure gradient in 50 fasting patients at hepatic venography. Immediately afterwards, a duplex sonographic examination of the liver was performed at which multiple measurements and indices of the venous and arterial hepatic vasculature were made. RESULTS: Hepatic arterial acceleration was correlated directly with the hepatic venous pressure gradient (r = 0.83, P < 0.0001) and with the Child-Pugh score (r = 0.63, P < 0.0001). An acceleration index cut-off value of 1 m.s{sup -2} provided a positive predictive value of 95%, a sensitivity of 65% and a specificity of 95% for detecting patients with severe portal hypertension (hepatic venous pressure gradient > 12 mmHg). A correlation between the hepatic venous pressure gradient and the congestion index of the portal vein velocity (r = 0.45,P = 0.01) and portal vein velocity (r = 0.40,P = 0.044), was also noted. CONCLUSION: Measuring the hepatic arterial acceleration index may help in the non-invasive evaluation of portal hypertension. Tasu, J.-P. et al. (2002)

    Purpose: to evaluate the clinical feasibility and safety of hepatic radiofrequency (RF) ablation using a multipolar RF system permitting the simultaneous use of up to six electrodes. Materials and methods: ten patients (3 female, 7 male, mean age 61) suffering from 29 hepatic metastases (range: 1-5) of different tumors were treated with a modified multipolar RF system (CelonLab Power, Celon Medical Instruments, Teltow, Germany) operating four to six needle-shaped internally cooled RF applicators. The procedure duration, applied energy and generator output were recorded during the intervention. The treatment result and procedure-related complications were analyzed. The achieved coagulation volume was calculated on the basis of contrast-enhanced CT scans 24 hours after RF ablation. Results: complete tumor ablation was achieved in all cases as determined by the post-interventional lack of contrast enhancement in the target region using four applicators in five patients, five applicators in one patient and six applicators in four patients. A mean energy deposition of 353.9 ± 176.2 kJ resulted in a mean coagulation volume of 115.9 ± 79.5 cm 3 . The mean procedure duration was 74.9 ± 21.2 minutes. Four patients showed an intraabdominal hemorrhage which necessitated further interventional treatment (embolization; percutaneous histoacryl injection) in two patients. (orig.)

  2. Hepatitis Associated Aplastic Anemia: A review

    Science.gov (United States)

    2011-01-01

    Hepatitis-associated aplastic anemia (HAAA) is an uncommon but distinct variant of aplastic anemia in which pancytopenia appears two to three months after an acute attack of hepatitis. HAAA occurs most frequently in young male children and is lethal if leave untreated. The etiology of this syndrome is proposed to be attributed to various hepatitis and non hepatitis viruses. Several hepatitis viruses such as HAV, HBV, HCV, HDV, HEV and HGV have been associated with this set of symptoms. Viruses other than the hepatitis viruses such as parvovirus B19, Cytomegalovirus, Epstein bar virus, Transfusion Transmitted virus (TTV) and non-A-E hepatitis virus (unknown viruses) has also been documented to develop the syndrome. Considerable evidences including the clinical features, severe imbalance of the T cell immune system and effective response to immunosuppressive therapy strongly present HAAA as an immune mediated mechanism. However, no association of HAAA has been found with blood transfusions, drugs and toxins. Besides hepatitis and non hepatitis viruses and immunopathogenesis phenomenon as causative agents of the disorder, telomerase mutation, a genetic factor has also been predisposed for the development of aplastic anemia. Diagnosis includes clinical manifestations, blood profiling, viral serological markers testing, immune functioning and bone marrow hypocellularity examination. Patients presenting the features of HAAA have been mostly treated with bone marrow or hematopoietic cell transplantation from HLA matched donor, and if not available then by immunosuppressive therapy. New therapeutic approaches involve the administration of steroids especially the glucocorticoids to augment the immunosuppressive therapy response. Pancytopenia following an episode of acute hepatitis response better to hematopoietic cell transplantation than immunosuppressive therapy. PMID:21352606

We collected basic demographic, medical, and laboratory data to determine predictors for coinfection. Results: Of 323 enrolled patients, 32 (9.9%; 95% CI=6.7-13.2% were HBsAg positive, while 4 (1.2%; 95% CI=0.03-2.4% were HCV Ab positive. Patients with hepatitis B coinfection were more likely to be 200 IU/L was uncommon and did not differ between the two groups (3.4% vs. 2.3%; P=0.5. We were unable to determine predictors of hepatitis C infection due to the low prevalence of disease. Conclusions: HIV and hepatitis B coinfection was common among patients initiating ART at this tertiary care facility. Routine screening for hepatitis B should be considered for HIV-infected persons in southern Africa.

    Hepatic veno-occlusive disease, also called sinusoidal obstruction syndrome (VOD/SOS), is an unpredictable and potentially fatal complication of hematopoietic cell transplantation (HCT) or nontransplantation-associated chemotherapy/radiotherapy. In cases of severe hepatic VOD/SOS, typically defined by associated multiorgan failure (MOF, also known as multiorgan dysfunction), mortality exceeds 80%. Preclinical and early clinical data have provided a rationale for defibrotide treatment in hepatic VOD/SOS. Based on this evidence and in recognition of the dismal prognosis for these patients, defibrotide was made available through an international multicenter compassionate-use program conducted from December 1998 to March 2009. Physicians participating in the program voluntarily provided demographic and outcome data for patients given defibrotide. Efficacy and safety analyses were performed using the data received for 710 treated patients. Defibrotide was given at 10, 25, 40, 60, or 80 mg/kg/day for a median of 15 days (range, 1 to 119 days). By Kaplan-Meier analysis, the estimated overall day +100 survival was 54% (58% in the 25 mg/kg/day dose group). Adverse events (AEs) were reported in 53% of patients. The most common AEs were MOF, progression of hepatic VOD/SOS, sepsis, and graft-versus-host disease, which were consistent with the AEs expected for this patient population. No clinically meaningful trends in AEs were identified by gender, age, or dose group.

    Hepatitis A virus (HAV) and hepatitis E virus (HEV) cause acute, self-limiting hepatic infections that are usually spread by the fecal-oral route in humans. Naturally occurring and experimental infections are possible in a variety of nonhuman primates and, in the case of HEV, a number of other species. Many advances in understanding the pathogenesis of these viruses have come from studies in experimental animals. In general, animals infected with these viruses recapitulate the histologic lesions seen in infected humans, but typically with less severe clinical and histopathological manifestations. This review describes the histopathologic changes associated with HAV and HEV infection in humans and experimental animals. Copyright © 2018 Cold Spring Harbor Laboratory Press; all rights reserved.

    A case of hepatic encephalopathy induced by thorotrast injected as a contrast 40 years before was reported. The patient was a 64-year-old man with severe liver dysfunction, and had psychic and neurological symptoms, and hyperammonemia. There was a relationship between ammonium concentration in blood and psychic and neurological symptoms. Electroencephalogram showed three phases waves peculiar to hepatic coma intermittently. Throtrast in the liver was detected by radiological methods and in vivo measurement of the radioactivity. From the above-mentioned result, this disease was diagnosed as hepatic encephalopathy induced by long-term sedimentation of thorotrast without complication of malignant tumors. Because of the concurrent presence of cerebral infarction, the diagnosis was difficult to make. (Tsunoda, M.)

    The specialty literature of the last decade presents the nonoperative management of the closed abdominal trauma as the treatment of choice. The purpose of this study is to highlight the importance of the optimal management of hepatic lesions considering the clinical, paraclinical and therapeutic approach. Our study is based on the analysis of the clinical and paraclinical data and also on the evaluation of the treatment results in 1671 patients with abdominal trauma affecting multiple organs who were treated at the Clinic of Surgery, County Hospital of Oradea from 2008 to 2011. The non-operative approach of the hepatic trauma, applied in 52% of the patients, was indicated in stable hemodynamic status, non-bleeding hepatic lesions on the abdominal CT, and the absence of other significant abdominal lesions. The remaining 48% were treated surgically. The postoperative evolution was free of complications in 72% of the patients while the rest of 28% presented one or more postoperative complications.

    The most highly developed radioimmunoassay test system in medical virology is proving of exceptional value in research aimed at controlling and eventually eradicating the scourge of human hepatitis. The use of radioimmunoassay in detecting hepatitis A (HAV) and hepatitis B (HBV) viruses is discussed. The hepatitis A virus is an enterovirus which infects the gastrointestinal tract and is usually transmitted by contaminated food, milk or water. Hepatitis B spreads mainly by the parenteral rate. Bedbugs and ticks are considered as possible transmitters of HBV. Another important contribution of radioimmunoassay is the ability to monitor the immune response of persons at risk who are vaccinated against hepatitis B.

    To evaluate the relationship between the waveform of the right hepatic vein and the histological grade and stage in patients with chronic hepatitis B. Eighty-seven patients with chronic hepatitis B were examined prospectively by one sonographer. In each patient, Doppler waveform of the right hepatic vein was obtained. Doppler waveform was classified into 3 type, type 0; normal triphasic pattern, type 1; reduced amplitude of phasic oscillation and no reverse flow phase, and type 2; completely flat flow pattern. In the same session, an ultrasound guided liver biopsy was performed and submitted to one pathologist for grading and staging. Duplex doppler ultrasonography of the right hepatic vein was also performed in 12 control subjects with no evidence of liver or heart disease. The doppler waveform was compared with the histologic severity and a statistical analysis was performed. In the control group, all cases had type 0 waveform. In the hepatitis group, there were type 0 waveform in 61 cases (70.1%), type 1 waveform in 22 cases (25.3%) and type 2 waveform in 4 cases (4.6%). The frequency of abnormal waveform is significantly higher in patients with grade 3-4 and stage 3-4 than grade and stage 1-2 (p>0.005). In the hepatitis group, the venous pulsatility index (VPI) was 0.17-0.69 (mean 0.41), and decreased in the highest and mean values when increasing the histologic scores. However, it was nor significant statistically (p>0.05). The frequency of abnormal waveform was correlated with the histologic severity in patients with chronic hepatitis B. The highest and mean values of the VPI were also correlated. However 70.1% of the patients with chronic hepatitis B showed normal waveform. So doppler ultrasonogram of the hepatic vein may be useful for the diagnosis and the differential diagnosis from cirrhosis in patients with chronic hepatitis B by combination of doppler waveform and venous pulsatility index.

    This study shows epidemiological characteristics and preventive measures implemented for the prevention and control of hepatitis B infections in Croatia. We analyzed the data from obligatory infectious disease reports and notifications of death due to infectious diseases, data on the hepatitis B infections in Croatia, and data collected by survey of the population. The average prevalence of the disease is 3.67 per 100,000 annually. All age groups are affected, but still a higher rate of the disease is found in the age groups from 15-19 and 20-29 years of age. Hepatitis B disease is 1.4 times more likely in men than in women. For the past 18 years, the average rate of mortality was 0.2%. The incidence of HbsAg-positive donors of blood is within the range of 0.65% in 1992 to 0.012% in 2011. The largest part of preventive measures implemented in Croatia against hepatitis B is predicted and required by legislation. The registrations of acute and chronic carriers of the virus are obligatory. High-risk groups have started being vaccinated since 1992. The obligatory vaccination of infants was introduced in the mandatory vaccination program in 2007. Routine testing of blood exclusively from voluntary donors for HbsAg presence is obligatory. The non-governmental organization "Help" created for intravenous drug users, along with the "Harm reduction" program implemented hepatitis B, C, and HIV/AIDS prevention program in 1995. In order to gain a better understanding of epidemiological characteristics of hepatitis B in Croatia, the specifics of its dynamics in small communities are required since the research of Croatian public health officials and researchers have shown that hepatitis B is spread in different ways.

    Momelotinib is a Janus kinase 1/2 inhibitor in clinical development for the treatment of myelofibrosis. Two phase 1 open-label, parallel-group, adaptive studies were conducted to evaluate the pharmacokinetics of a single 200-mg oral dose of momelotinib in subjects with hepatic or renal impairment compared with healthy matched control subjects with normal hepatic or renal function. Plasma pharmacokinetics of momelotinib and its major active metabolite, M21, were evaluated, and geometric least-squares mean ratios (GMRs) and associated 90% confidence intervals (CIs) for impaired versus each control group were calculated for plasma exposures (area under concentration-time curve from time 0 to ∞ [AUC ∞ ] and maximum concentration) of momelotinib and M21. There was no clinically significant difference in plasma exposures of momelotinib and M21 between subjects with moderate or severe renal impairment or moderate hepatic impairment and healthy control subjects. Compared with healthy control subjects, momelotinib AUC ∞ was increased (GMR, 197%; 90%CI, 129%-301%), and M21 AUC ∞ was decreased (GMR, 52%; 90%CI, 34%-79%) in subjects with severe hepatic impairment. The safety profile following a single dose of momelotinib was similar between subjects with hepatic or renal dysfunction and healthy control subjects. These pharmacokinetic and safety results indicate that dose adjustment is not necessary for momelotinib in patients with renal impairment or mild to moderate hepatic impairment. In patients with severe hepatic impairment, however, the dose of momelotinib should be reduced. © 2017, The American College of Clinical Pharmacology.

  18. Alcoholic Hepatitis Markedly Decreases the Capacity for Urea Synthesis.

    Emilie Glavind

    Full Text Available Data on quantitative metabolic liver functions in the life-threatening disease alcoholic hepatitis are scarce. Urea synthesis is an essential metabolic liver function that plays a key regulatory role in nitrogen homeostasis. The urea synthesis capacity decreases in patients with compromised liver function, whereas it increases in patients with inflammation. Alcoholic hepatitis involves both mechanisms, but how these opposite effects are balanced remains unclear. Our aim was to investigate how alcoholic hepatitis affects the capacity for urea synthesis. We related these findings to another measure of metabolic liver function, the galactose elimination capacity (GEC, as well as to clinical disease severity.We included 20 patients with alcoholic hepatitis and 7 healthy controls. The urea synthesis capacity was quantified by the functional hepatic nitrogen clearance (FHNC, i.e., the slope of the linear relationship between the blood α-amino nitrogen concentration and urea nitrogen synthesis rate during alanine infusion. The GEC was determined using blood concentration decay curves after intravenous bolus injection of galactose. Clinical disease severity was assessed by the Glasgow Alcoholic Hepatitis Score and Model for End-Stage Liver Disease (MELD score.The FHNC was markedly decreased in the alcoholic hepatitis patients compared with the healthy controls (7.2±4.9 L/h vs. 37.4±6.8 L/h, P<0.01, and the largest decrease was observed in those with severe alcoholic hepatitis (4.9±3.6 L/h vs. 9.9±4.9 L/h, P<0.05. The GEC was less markedly reduced than the FHNC. A negative correlation was detected between the FHNC and MELD score (rho = -0.49, P<0.05.Alcoholic hepatitis markedly decreases the urea synthesis capacity. This decrease is associated with an increase in clinical disease severity. Thus, the metabolic failure in alcoholic hepatitis prevails such that the liver cannot adequately perform the metabolic up-regulation observed in other stressful

    Hepatitis B virus (HBV) and hepatitis C virus (HCV), discovered as causative viruses of post-transfusion hepatitis, become persistent infections, leading to chronic hepatitis, cirrhosis, and hepatocellular carcinoma (HCC). For HCV, recent IFN-free direct-acting antiviral (DAA) therapies have increased sustained virological response (SVR) rates and reduced adverse events. IFN-based therapies, still the standard of care in Asian countries, are influenced by IL28B genetic variants and the liver fibrosis stage, but the DAA combinations obscure the influence of these factors. These new therapies can eradicate HCV and prevent HCC development. On the other hand, it is difficult to eradicate HBV completely. Although HBV infection can be prevented by vaccination, reactivation of HBV following anti-cancer chemotherapy and immunosuppressive therapy is a well-known complication. HBV reactivation has been reported to be associated with anti-CD20 monoclonal antibody rituximab-containing chemotherapy and TNF-α inhibitor-containing immunosuppressive therapy in HBV-resolved patients. Our prospective observational study revealed that monthly monitoring of HBV DNA was useful for preventing HBV reactivation-related hepatitis among B-cell non-Hodgkin lymphoma patients with resolved HBV infection following rituximab-steroid-chemo, suggesting that preemptive therapy guided by serial HBV DNA monitoring should be recommended. Recently, highly sensitive HBsAg detection by Lumipulse HBsAg-HQ may be useful for several clinical applications. The sensitivity of this assay (5 mIU/mL) was approximately 10-fold higher than Abbott ARCHITECT, but still lower than HBV-DNA assays. The convenient HBsAg-HQ may be useful for detecting occult HBV infection and HBV reactivation in relatively low-risk groups except for those receiving rituximab-steroid-chemo. [

    Acquired aplastic anemia(aAA is a severe and rare disease, characterized by hematopoietic bone marrow failure and peripheral cytopenia. The pathophysiology is immune mediated in most cases, activated T1 lymphocytes have been identified as effector cells . The disease can be successfully treated with combined immunosuppressive therapy or allogeneic hematopoietic stem cell transplantation.

    Hepatitis-associated aplastic anemia (HAA  is a syndrome of bone marrow failure following the development of acute seronegative hepatitis. HAA syndrome most often affects young males who presented severe pancytopenia two to three months after an episode of acute hepatitis. The clinical course of hepatitis is more frequently benign but a fulminant severe course is also described. The bone marrow failure can be explosive and severe and it is usually fatal if untreated, no correlations have been observed between severity of hepatitis and AA.

    In none of the  studies a specific virus could be identified and most cases are seronegative for known hepatitis viruses. The clinical characteristics  and response to immunotherapy indicate a central role for immune-mediated mechanism in the pathogenesis of HAA. The initial

    Alcohol is one of the most common etiologies of liver disease,and alcoholic liver disease overall is the second most common indication for liver transplantation in the United States.It encompasses a spectrum of disease,including fatty liver disease,alcoholic hepatitis (AH),and alcoholic cirrhosis.AH can range from mild to severe disease,with severe disease being defined as:Discriminant Function (DF) ≥ 32,or Model for End-stage Liver Disease (MELD) ≥ 21,or presence of hepatic encephalopathy.Management of the mild disease consists mainly of abstinence and supportive care.Severe AH is associated with significant mortality.Currently,there is no ideal medical treatment for this condition.Besides alcohol cessation,corticosteroids have been used with conflicting results and are associated with an inherent risk of infection.Overall steroids have shown short term benefit when compared to placebo,but they have no obvious long term benefits.Pentoxifylline does not improve survival in patients with severe AH and is no longer recommended based on the results of the STOPAH (Steroid Or Pentoxifylline for Alcoholic Hepatitis) trial.Anti-tumor necrosis factor (TNF) agents are associated with increased risk of life threatening infections and death.Currently,early stage trials are underway,mainly targeting novel pathways based on disease pathogenesis,including modulation of innate immune system,inhibition of gut-liver axis and cell death pathways,and activation of transcription factor farnesyl X receptor (FXR).Future treatment may lie in human induced pluripotent stem cell (iPSC)technology,which is currently under investigation for the study of pathogenesis,drug discovery,and stem cell transplantation.Liver transplantation has been reported with good results in highly selected patients but is controversial due to limited organ Suppply.

    Hepatic steatosis is a common feature of patients with chronic hepatitis C. Previous reports have shown that the overexpression of hepatitis C virus core-encoding sequences (hepatitis C virus genotypes 3a and 1b) significantly induces intracellular triglyceride accumulation. However, the underlying mechanism has not yet been revealed. To investigate whether Sirt1 is involved in hepatitis C virus-mediated hepatic steatosis, the overexpression of hepatitis C virus core 1b protein and Sirt1 and the knockdown of Sirt1 in HepG2 cells were performed. To confirm the results of the cellular experiment liver-specific Sirt1 KO mice with lentivirus-mediated hepatitis C virus core 1b overexpression were studied. Our results show that hepatitis C virus core 1b protein overexpression led to the accumulation of triglycerides in HepG2 cells. Notably the expression of PPARγ2 was dramatically increased at both the mRNA and protein levels by hepatitis C virus core 1b overexpression. The protein expression of Sirt1 is an upstream regulator of PPARγ2 and was also significantly increased after core 1b overexpression. In addition, the overexpression or knockdown of Sirt1 expression alone was sufficient to modulate p300-mediated PPARγ2 deacetylation. In vivo studies showed that hepatitis C virus core protein 1b-induced hepatic steatosis was attenuated in liver-specific Sirt1 KO mice by downregulation of PPARγ2 expression. Sirt1 mediates hepatitis C virus core protein 1b-induced hepatic steatosis by regulation of PPARγ2 expression. © 2017 John Wiley & Sons A/S. Published by John Wiley & Sons Ltd.

    Full Text Available OBJECTIVES: The incidence of hepatitis A infections among young adults has recently increased in South Korea. Although universal vaccination has often been suggested to mitigate the problem, its rationale has not been well-understood. Estimating the societal costs of hepatitis A infections might support the development of intervention strategies. METHODS: We classified hepatitis A infections into eight clinical pathways and estimated the number of occurrences and cost per case for each clinical pathway using claim data from National Health Insurance and several national surveys as well as assumptions based on previous studies. To determine the total costs of a hepatitis A infection, both direct and indirect costs were estimated. Indirect costs were estimated using the human-capital approach. All costs are adjusted to the year 2008. RESULTS: There were 30,240 identified cases of hepatitis A infections in 2008 for a total cost of 80,873 million won (2.7 million won per case. Direct and indirect costs constituted 56.2% and 43.8% of the total costs, respectively. People aged 20-39 accounted for 71.3% of total cases and 74.6% of total costs. Medical costs per capita were the lowest in the 0-4 age group and highest in the 20-29 age group. CONCLUSIONS: This study could provide evidence for development of cost-effective interventions to control hepatitis A infections. But the true costs including uncaptured and intangible costs of hepatitis A infections might be higher than our results indicate.

    To evaluate the clinical significance of RI images of hepatic blood flow using Tc-99m-PMT, analysis of the RI images and estimation of hepatic blood flow were carried out in patients with various liver diseases (37 cases). After intravenous injection of Tc-99m-PMT, hepatic accumulation curve of ROI positioned at whole liver area and time activity curve of ROI positioned at celiac artery were obtained through scintillation camera images with the computer-analysed system. Hepatic blood flow coefficient (K) was calculated from the hepatic accumulation curve. Based on the differential curve calculated from the time activity curve, chronological images of arterial, portal, parenchymal and saturated parenchymal phases were obtained. Results ; 1) K was 0.50 + 0.04, 0.35 + 0.02 and 0.26 + 0.04/min in normal type, CH type and LC type respectively. These coefficients well correlated with clinical severity of hepatic diseases. 2) Perfusional phase images of the liver became poorer in accordance with progression of liver disease, while images of spleen, portal venous system and collateral channels were more clearly obtained in liver cirrhosis. This method was shown to have a potential to understanding of severity of liver disease and hepatic blood flow dynamics.

    The diagnosis of hepatitis A infection is usually based on the presence of hepatitis A specific IgM in a single serum sample. The fortuitous observation in one patient that this reactivity was apparently still present 19 mth after her original illness led to the discovery that the ABBOTT HAVAB-M kit method may produce false positive results. A series of patients who had previously had hepatitis A was retested and false positive results were found in 6% of this group. Control groups consisted of patients with other acute and chronic liver disorders and other acute viral diseases. No reactivity was detected in the control sera. Sucrose gradient fractionation revealed that the factor responsible for the false positive results was associated only with serum fractions containing IgA and IgG and that it could be removed by absorption of sera with staphylococcal protein A but not by absorption with streptococcus AR1 or by 2-mercaptoethanol treatment. It was concluded that following hepatitis A infection some patients produce a rheumatoid factor-like substance (not of IgM class) which is cleared from the serum in 2-3 yr. The presence of this factor may lead to a misdiagnosis in patients presenting with jaundice.

    Background: Liver biopsy is the standard method for diagnosis of hepatic steatosis, but is invasive and carries some risk of morbidity. Aims and methods: Quantification of hepatocellular lipid content (HCL) with non-invasive single voxel {sup 1}H magnetic resonance spectroscopy (MRS) at 3 T was compared with histological grading and biochemical analysis of liver biopsies in 29 patients with chronic hepatitis C. Body mass index, indices of insulin resistance (homeostasis model assessment index, HOMA-IR), serum lipids and serum liver transaminases were also quantified. Results: HCL as assessed by {sup 1}H MRS linearly correlated (r = 0.70, p < 0.001) with histological evaluation of liver biopsies and was in agreement with histological steatosis staging in 65% of the patients. Biochemically assessed hepatic triglyceride contents correlated with HCL measured with {sup 1}H MRS (r = 0.63, p < 0.03) and allowed discriminating between none or mild steatosis versus moderate or severe steatosis. Patients infected with hepatitis C virus genotype 3 had a higher prevalence of steatosis (62%) which was not explained by differences in body mass or whole body insulin resistance. When these patients were excluded from correlation analysis, hepatic fat accumulation positively correlated with insulin resistance in the remaining hepatitis C patients (HCL vs. HOMA-IR, r = 0.559, p < 0.020, n = 17). Conclusion: Localized {sup 1}H MRS is a valid and useful method for quantification of HCL content in patients with chronic hepatitis C and can be easily applied to non-invasively monitoring of steatosis during repeated follow-up measurements in a clinical setting.

    Dementia induced by β-amyloid accumulation impairs peripheral glucose homeostasis, but red pepper extract improves glucose homeostasis. We therefore evaluated whether long-term oral consumption of different red pepper extracts improves cognitive dysfunction and glucose homeostasis in type 2 diabetic rats with β-amyloid-induced dementia. Male diabetic rats received hippocampal CA1 infusions of β-amyloid (25-35) (AD) or β-amyloid (35-25, non-plaque forming), at a rate of 3.6 nmol/day for 14 days (Non-AD). AD rats were divided into four dietary groups receiving either 1% lyophilized 70% ethanol extracts of either low, moderate and severe pungency red peppers (AD-LP, AD-MP, and AD-SP) or 1% dextrin (AD-CON) in Western diets (43% energy as fat). The ascending order of control memory deficit measured by passive avoidance test and water maze test. Furthermore, the accumulation of β-amyloid induced glucose intolerance, although serum insulin levels were elevated during the late phase of oral glucose tolerance test (OGTT). All of the red pepper extracts prevented the glucose intolerance in AD rats. Consistent with OGTT results, during euglycemic hyperinulinemic clamp glucose infusion rates were lower in AD-CON than Non-AD-CON with no difference in whole body glucose uptake. Hepatic glucose output at the hyperinsulinemic state was increased in AD-CON. β-amyloid accumulation exacerbated hepatic insulin resistance, but all red pepper extract treatments reversed the insulin resistance in AD rats. The extracts of moderate and severe red peppers were found to prevent the memory deficit and exacerbation of insulin resistance by blocking tau phosphorylation and β-amyloid accumulation in diabetic rats with experimentally induced Alzheimer's-like dementia. These results suggest that red pepper consumption might be an effective intervention for preventing age-related memory deficit.

    The hepatic hematoma or rupture appear in 1 of every 100,000 pregnancies. The most common causes of hepatic hematoma in pregnancy are severe preeclampsia and HELLP syndrome; some predisposing factors are seizures, vomiting, labor, preexistent hepatic disease and trauma. A 33 year old primigravid with a normal 33 week twin pregnancy presented abdominal pain and hypovolemic shock due to spontaneous subcapsular hepatic hematoma; laparoscopy was performed to evaluate the possibility of rupture, which was not found, later emergency cesarean section was carried out followed by hepatic hematoma drainage and abdominal packaging by laparoscopy. After surgery the flow through drainage was too high additionally hemodynamic instability and consumption coagulopathy. Abdominal panangiography was performed without identifying bleeding areas. Intesive care was given to the patient evolving satisfactorily, was discharged 19 days after the event. Seven months later she had laparoscopic cholecystectomy due to acute litiasic colecistitis. We found 5 cases in literatura about hepatic hematoma during pregnancy no related to hypertensive disorders of pregnancy; these were related to hepatoma, amebian hepatic abscess, falciform cell anemia, cocaine consumption and molar pregnancy. Hepatics hematomas have high morbidity and mortality so is significant early diagnosis and multidisciplinary approach.

    A retrospective study over 26 female patients with chronic active hepatitis was made. The mean age was 39 years old, the mean length of illness of 8 months; 5 patients had positive markers for hepatitis B. Patients were selected with the grade of histological activity: 8 patients had a mild form from disease (2A) and 16 with a severe one (2B). The predominant group was 2B. Severe inflammatory infiltration was the hallmark and multiobulillar necrosis, bridging, eosinophils and hiperplasia of kuppfer cells were found only in this group. Clinical features range from hepatic manifestations to systemic ones. Chronic active hepatitis may present with cholestasis, but the latter is not always related with the grade of activity. Group 2B had elevated aminotransferases and a low concentration for protrobine.

    Various methods to determine hepatic function have been studied, and among these, calculated maximal removal rate of ICG (ICG R-max) is more accurate and sensitive index for quantification of hepatic function. But calculation of ICG R-max is time-consuming, invasive, and expensive study, and even ICG R-max 1 day study is still complicated. So we tried to evaluated of hepatic function test using 99mTc-DISIDA plasma clearance rate. The author studied 11 cases of normal control, 4 cases of acute hepatitis, 8 cases of chronic hepatitis, and 19 cases of liver cirrhosis. The results were as follows: 1. In normal control, DISIDA-K was 0.70 min -1 , in liver cirrhosis 0.25 min -1 , in acute hepatitis 0.46 min -1 , and in chronic hepatitis 0.14min -1 . The most severe depressed DISIDA-K value was observed in liver cirrhosis. 2. Comparison of DISIDA-K value to liver function indices revealed no correlation between DISIDA-K value and serum albumin, prothrombin time, total bilirubin, SGOT, and alkaline phosphatase. 3. DISIDA-K value in liver cirrhosis with complication such as ascites, splenomegaly, esophageal varices, and hepatic coma was more decreased than without complication. With the above result, calculation of DISIDA-K value was found easily available, accurate, and simple index for quantification of hepatic function.

  14. Hepatitis E virus as a Cause of Acute Hepatitis in The Netherlands.

    Directory of Open Access Journals (Sweden)

    Aletta T R Tholen

    Full Text Available Recent studies indicate that 27% of Dutch blood donors have evidence of past infection with HEV. However, the low number of diagnosed HEV infections indicates either an asymptomatic course or under diagnosis.We investigated whether HEV is a cause of acute hepatitis in Dutch patients and which diagnostic modality (serology or PCR should be used for optimal detection.Serum samples were retrospectively selected from non-severely immuno-compromised patients from a university hospital population, suspected of having an infectious hepatitis. Criteria were: elevated alanine aminotransferase (ALT> 34 U/l and request for antibody testing for CMV, EBV or Hepatitis A (HAV.All samples were tested for HEV using ELISA and PCR. Ninety patients/sera were tested, of which 22% were HEV IgG positive. Only one serum was IgM positive. HEV PCR was positive in two patients: one patient was both HEV IgM and IgG positive, the other patient was only IgG positive. Both HEV RNA positive samples belonged to genotype 3. Evidence of recent infection with CMV, EBV and HAV was found in 13%, 10% and 3% respectively.Although our study is limited by small numbers, we conclude that HEV is a cause of acute hepatitis in hospital associated patients in The Netherlands. Moreover, in our study population the prevalence of acute HAV (3% was almost similar to acute HEV (2%. We propose to incorporate HEV testing in panels for acute infectious hepatitis. Negative results obtained for HEV IgM in a HEV PCR positive patient, indicates that antibody testing alone may not be sufficient and argues for PCR as a primary diagnostic tool in hospital associated patients. The high percentage of HEV IgG seropositivity confirms earlier epidemiological studies.

    Full Text Available Ticlopidine hydrochloride has been shown to reduce the risk of first or recurrent stroke in patients who have experienced a transient ischemic attack, reversible ischemic neurological deficit, recurrent stroke or first stroke. Severe liver dysfunction is a contraindication for its use. Increase in liver enzymes has been reported with use of this drug, but jaundice is rare. A case of severe ticlopidine-induced hepatitis that was associated with a marked increase in antinuclear antibody (ANA levels is reported. Physicians prescribing ticlopidine hydrochloride should be aware that a potentially severe acute hepatitis associated with ANA positivity can occur. The drug should be discontinued if signs of liver dysfunction occur.

    Autoimmune hepatitis is a rare, chronic inflammatory disorder which has been associated with a number of other auto-immune conditions. However, there are no reports in the medical literature of an association with microscopic (lymphocytic) colitis. We report the case of a 53-year-old woman with several autoimmune conditions, including lymphocytic colitis, who presented with an acute hepatitis. On the basis of the clinical features, serology, and histopathology, we diagnosed autoimmune hepatitis. To our knowledge, this is the first report of autoimmune hepatitis in association with lymphocytic colitis, and lends support to the theory of an autoimmune etiology for lymphocytic colitis.

  17. Plasma hydroxy-metronidazole/ metronidazole ratio in hepatitis C virus-induced liver disease

    Full Text Available It has been suggested that the measurement of metronidazole clearance is a sensitive method for evaluating liver function. The aim of this study was to evaluate the usefulness of plasma hydroxy-metronidazole/metronidazole ratios as indicators of dynamic liver function to detect changes resulting from the various forms of chronic hepatitis C virus (HCV infection. A total of 139 individuals were studied: 14 healthy volunteers, 22 healthy, asymptomatic, consecutive anti-HCV-positive HCV-RNA negative subjects, 81 patients with chronic hepatitis C (49 with moderate/severe chronic hepatitis and 34 with mild hepatitis, and 20 patients with cirrhosis of the liver. HCV status was determined by the polymerase chain reaction. Plasma concentrations of metronidazole and its hydroxy-metabolite were measured by reverse-phase high-performance liquid chromatography with ultraviolet detection in a blood sample collected 10 min after the end of a metronidazole infusion. Anti-HCV-positive HCV-RNA-negative individuals demonstrated a significantly reduced capacity to metabolize intravenously infused metronidazole compared to healthy individuals (0.0478 ± 0.0044 vs 0.0742 ± 0.0232. Liver cirrhosis patients also had a reduced plasma hydroxy-metronidazole/metronidazole ratio when compared to the other groups of anti-HCV-positive individuals (0.0300 ± 0.0032 vs 0.0438 ± 0.0027 (moderate/severe chronic hepatitis vs 0.0455 ± 0.0026 (mild chronic hepatitis and vs 0.0478 ± 0.0044 (anti-HCV-positive, HCV-RNA-negative individuals. These results suggest an impairment of the metronidazole metabolizing system induced by HCV infection that lasts after viral clearance. In those patients with chronic hepatitis C, this impairment is paralleled by progression of the disease to liver cirrhosis.

    Full Text Available Weili Zhan, Yanhong Kang, Ning Chen, Chongshan Mao, Yi Kang, Jia Shang Department of Infectious Diseases, Henan Provincial People’s Hospital, Zhengzhou, Henan, China Abstract: The hepatitis B virus (HBV has caused acute and chronic liver diseases in ~350 million infected people worldwide. Halofuginone (HF is a plant alkaloid which has been demonstrated to play a crucial role in immune regulation. Our present study explored the function of HF in the immune response of HBV-infected Sprague Dawley (SD rats. Plasmid containing pCDNA3.1-HBV1.3 was injected in SD rats for the construction of an acute HBV-infected animal model. Our data showed that HF reduced the high concentrations of serum hepatitis B e-antigen, hepatitis B surface antigen, and HBV DNA induced by HBV infection. HF also reduced the number of T helper (Th17 cells and the expression of interleukin (IL-17 compared with the pCDNA3.1-HBV1.3 group. Moreover, pro-inflammatory cytokine levels (IL-17, IL-23, interferon-γ, and IL-2 were downregulated and anti-inflammatory cytokine levels (IL-4 and IL-13 were upregulated by HF. Through further research we found that the expression of AMP-activated protein kinase (AMPK and IKBA which suppressed NF-κB activation was increased while the expression of p-NF-κB P65 was decreased in pCDNA3.1-HBV1.3+HF group compared with pCDNA3.1-HBV1.3 group, indicating that HF may work through the activation of AMPK. Finally, our conjecture was further verified by using the AMPK inhibitor compound C, which counteracted the anti-inflammation effect of HF, resulting in the decreased expression of AMPK, IKBA and increased expression of p-NF-κB P65 and reduced number of Th17 cells. In our present study, HF was considered as an anti-inflammatory factor in acute HBV-infected SD rats and worked through AMPK-mediated NF-κB p65 inactivation. This study implicated HF as a potential therapeutic strategy for hepatitis B. Keywords: halofuginone, hepatitis B virus

  1. Recent Advances in the Assessment of Hepatic Steatosis

    2015-09-01

    Full Text Available The article deals with a review of scientific works on the issue of hepatic steatosis verification. Nowadays, the problem of timely detection and treatment of chronic diffuse liver diseases, in the pathogenesis of which fibrosis and hepatic steatosis play key role, becomes more and more important. It is recognized that hepatic steatosis is characterized by the accumulation of lipids in hepatocytes exceeding 5 % of the liver mass. In recent years, special attention is paid to the methods for verification of hepatic steatosis, which can be divided into invasive, minimally invasive and non-invasive. Invasive methods are still relevant, they include liver core needle biopsy — the gold standard. Minimally invasive methods for hepatic steatosis verification are based on the biochemical study of venous blood. Minimally invasive methods can be conditionally divided into routine — triglycerides, total cholesterol, high density lipoproteins etc., and calculated coefficients: SteatoTest and others. Their results are calculated on the basis of several indicators. Non-invasive methods of verification include: ultrasound, computed tomography, magnetic resonance imaging, elastometry with CAP™function (Fibroscan, model 502. In our opinion, for verification of hepatic steatosis, it is promising to use the ultrasound with the option of measuring the parameters of arterial stiffness in the WТrack mode. Among the non-invasive methods of hepatic steatosis verification, liver elastometry using FibroScan-502-touch device with CAP™ function made a breakthrough in some specific sense. Opening possibilities for early detection of hepatic steatosis enable to place on timely preventive and therapeutic measures and to create the conditions for stopping the progression, and possibly for the regression of hepatic steatosis.

    The author observed the serum levels of carboxy terminal peptide of type I procollagen (PICP) and epidermal growth factor (EGF) in the patients with viral hepatitis and cirrhosis. The serum PICP and EGF were detected in 164 cases by RIA. The results indicated that two indexes increased significantly in patients with severe chronic hepatitis, chronic persistent hepatitis and post hepatitis cirrhosis compared with normal control (P 0.05). The results showed that detection of serum PICP and EGF may be valuable diagnostic markers to assess the degree of liver inflammation and fibrosis in viral liver diseases

    Hepatic sinusoidal obstruction syndrome (SOS) is a life-threatening syndrome that generally occurs as a complication after hematopoietic stem cell transplantation or, less commonly, after conventional chemotherapy. Regarding SOS in rhabdomyosarcoma patients who received conventional chemotherapy, the doses of chemotherapeutic agents are associated with the development of SOS. Several cases of SOS in rhabdomyosarcoma patients after receiving chemotherapy with escalated doses of cyclophosphamide have been reported. Here, we report on a 9-year-old female with rhabdomyosarcoma who developed severe SOS after receiving chemotherapy consisting of vincristine, actinomycin-D, and a moderate dose of cyclophosphamide. She was treated successfully with defibrotide without sequelae to the liver.

    Neuropsychiatric symptoms of hepatitis C virus (HCV) infection and during peginterferon α therapy have been investigated in the chronic stage of the infection, but have not been described during the acute phase of the disease so far. We therefore evaluated anxiety and depression in patients with acute hepatitis C by the Hospital Anxiety and Depression Scale (HADS) within a clinical trial. Data were analysed from the German Hep-Net Acute HCV-III study. Anxiety and depression were characterized by an anxiety (HADS-A) and a depression subscale (HADS-D). More than eight points in each subscale were considered clinically relevant. Data were prospectively collected at baseline, end of treatment and at the end of the study. At baseline, a HADS-A above eight points was observed significantly more frequently than a HADS-D above eight points [n=23/103 (22%) vs. n=12/103 (12%); P=0.041].A pathological HADS-A or HADS-D score did not correlate with age, sex, IL28B genotype, the probable mode of infection, HCV genotype or severity of disease as investigated by alanine aminotransferase and bilirubin levels.Antiviral therapy did not influence anxiety as 12/50 (24%) of patients had HADS-A above 8 at the end of therapy. The proportion of patients with HADS-D above eight points increased from 12% at baseline to 24% (n=12/50) at the end of therapy (P=0.06). HADS results were not associated with lost to follow-up or sustained virological response rates. HADS data in acute HCV infection indicate that anxiety and depression do not correlate with severity of the disease, mode of acquisition, lost to follow-up and sustained virological response rates.

    Acute hepatic encephalopathy is a poorly defined syndrome of heterogeneous aetiology. We report a 49-year-old woman with alcoholic cirrhosis and hereditary haemorrhagic telangiectasia who developed acute hepatic coma induced by severe gastrointestinal bleeding. Laboratory analysis revealed excessively elevated blood ammonia. MRI showed lesions compatible with chronic hepatic encephalopathy and widespread cortical signal change sparing the perirolandic and occipital cortex. The cortical lesions resembled those of hypoxic brain damage and were interpreted as acute toxic cortical laminar necrosis. (orig.)

    Autoimmune hepatopathies (AIHT) including autoimmune hepatitis (AIH), primary biliary cirrhosis (PBC), primary sclerosing cholangitis (PSC) and autoimmune cholangitis (AIC), represent an impressive entities in clinical practice. Their pathogenesis is not perfectly elucidated. Several factors are involved in the initiation of hepatic autoimmune and inflammatory phenomena such as genetic predisposition, molecular mimicry and/or abnormalities of T-regulatory lymphocytes. AIHT have a wide spectrum of presentation, ranging from asymptomatic forms to severe acute liver failure. The diagnosis of AIHT is based on the presence of hyperglobulinemia, cytolysis, cholestasis, typical even specific circulating auto-antibodies, distinctive of AIH or PBC, and histological abnormalities as well as necrosis and inflammation. Anti-F actin, anti-LKM1, anti-LC1 antibodies permit to distinguish between AIH type 1 and AIH type 2. Anti-SLA/LP antibodies are rather associated to more severe hepatitis, and particularly useful for the diagnosis of seronegative AIH for other the antibodies. Due to the relevant diagnostic value of anti-M2, anti-Sp100, and anti-gp210 antibodies, the diagnosis of PBC is more affordable than that of PSC and AIC. Based on clinical data, the immunological diagnosis of AIHT takes advantage of the various specialized laboratory techniques including immunofluorescence, immunodot or blot, and the Elisa systems, provided of a closer collaboration between the biologist and the physician.

    1989-10-01

    The relation among the blood clearance of {sup 99m}Tc-phytake ({sup 99m}Tc-P), the hepatic uptake of {sup 99m}Tc-P and the severity of hepatic injury was investigated by using the rats with carbon tetrachloride (CCL{sub 4}), D-galactosamine (Gal N), alpha-naphthylisothiocyanate (ANIT) or DL-ethionine (EthN) induced hepatic injury. After the administration of CCL{sub 4}, GalN or ANIT, serum GPT activity increased significantly with the increase of dose level, and the degree of this increase was in the order: GalN>CCl{sub 4}>ANIT. However, the mild increase in serum GPT activity was observed after EthN administration. The blood clearance rate of {sup 99m}Tc-P and the hepatic uptake ratio of {sup 99m}Tc-P decreased with the increase of dose level after CCl{sub 4}, GalN or ANIT administration, but significant changes were not found after EthN administration. The degree of decrease in the blood clearance rate of {sup 99m}Tc-P was in the order: GalNapproxCCl{sub 4}>ANIT, and the degree of decrease in the hepatic uptake ratio of {sup 99m}Tc-P was in the order: GalNapproxCCl{sub 4}>ANIT. These results suggest that the disorder in the hepatocytes may be one of causes for inducing the decrease in the hepatic uptake of {sup 99m}Tc-P, and the consequence of this decrease may induce the decrease in the blood clearance of {sup 99m}Tc-P.

    Full Text Available Hepatitis C virus (HCV, a hepatotropic virus, is a single stranded-positive RNA virus of ~9,600 nt. length belonging to the Flaviviridae family. HCV infection causes acute hepatitis, chronic hepatitis, cirrhosis and hepatocellular carcinoma (HCC. It has been reported that HCV-coding proteins interact with host-cell factors that are involved in cell cycle regulation, transcriptional regulation, cell proliferation and apoptosis. Severe inflammation and advanced liver fibrosis in the liver background are also associated with the incidence of HCV-related HCC. In this review, we discuss the mechanism of hepatocarcinogenesis in HCV-related liver diseases.

    2012-05-01

    As life expectancy continues to rise, elderly adults represent a rapidly growing proportion of the population. The likelihood of complications of acute and chronic liver disease and overall mortality are higher in elderly populations. Several physiological changes associated with aging, greater prevalence of co-morbid conditions, and cumulative exposure to hepatotropic viruses and environmental hepatotoxins may contribute to worse outcomes of viral hepatitis in the elderly. Although pharmacotherapy for hepatitis B and C continues to evolve, the efficacy, tolerability, and side effects of these agents have not been studied extensively in elderly adults. Immunization against hepatitis A and B in naïve elderly adults is an important public health intervention that needs to be revised and broadened.

    Iron deposits demonstrate characteristically shortened T2 relaxation times. Several previously published studies reported poor correlation between the in vivo hepatic 1/T2 measurements made by means of midfield magnetic resonance (MR) units and the hepatic iron content of iron-overloaded patients. In this study, the authors assessed the use of in vivo 1/T2 measurements obtained by means of MR imaging at 0.5 T using short echo times (13.4 and 30 msec) and single-echo-sequences as well as computed tomographic (CT) attenuation as a measure of liver iron concentration in 10 severely iron-overloaded patients with beta-thalassemia major. The iron concentrations in surgical wedge biopsy samples of the liver, which varied between 3 and 9 mg/g of wet weight (normal, less than or equal to 0.5 mg/g), correlated well (r = .93, P less than or equal to .0001) with the preoperative in vivo hepatic 1/T2 measurements. The CT attenuation did not correlate with liver iron concentration. Quantitative MR imaging is a readily available noninvasive method for the assessment of hepatic iron concentration in iron-overloaded patients, reducing the need for needle biopsies of the liver

  14. Unusual Infections Complicating the Use of Steroids with Severe Alcoholic Hepatitis: Report of 2 Cases

    1995-01-01

    Full Text Available Corticosteroid therapy for acute alcoholic hepatitis has been demonstrated to enhance survival in patients who are encephalopathic, and who do not have renal failure or gastrointestinal bleeding. However, the complications of steroid therapy in such patients have been less well documented. The authors report two patients with alcoholic liver disease who developed life-threatening infections after steroid therapy was started. The first patient initially developed diabetes followed by Fournier's gangrene of the perineum, and a lung abscess following septic emboli. The second patient had established alcoholic cirrhosis rather than alcoholic hepatitis. She developed a necrotic ulcer on the arm at the site of an intravenous line, which was infected with a rhizopus species. Despite surgical debridement the lesion progressed and contributed to her death. Treatment of alcoholic hepatitis with steroids is not innocuous, and physicians should be aware of the potential for life-threatening complications.

    The aims of this study were to determine whether combining features of a western lifestyle in mice with trans fats in a high-fat diet, high-fructose corn syrup in the water, and interventions designed to promote sedentary behavior would cause the hepatic histopathological and metabolic abnormalities that characterize nonalcoholic steatohepatitis (NASH). Male C57BL/6 mice fed ad libitum high-fat chow containing trans fats (partially hydrogenated vegetable oil) and relevant amounts of a high-fructose corn syrup (HFCS) equivalent for 1-16 wk were compared with mice fed standard chow or mice with trans fats or HFCS omitted. Cage racks were removed from western diet mice to promote sedentary behavior. By 16 wk, trans fat-fed mice became obese and developed severe hepatic steatosis with associated necroinflammatory changes. Plasma alanine aminotransferase levels increased, as did liver TNF-alpha and procollagen mRNA, indicating an inflammatory and profibrogenic response to injury. Glucose intolerance and impaired fasting glucose developed within 2 and 4 wk, respectively. Plasma insulin, resistin, and leptin levels increased in a profile similar to that seen in patients with NASH. The individual components of this diet contributed to the phenotype independently; isocaloric replacement of trans fats with lard established that trans fats played a major role in promoting hepatic steatosis and injury, whereas inclusion of HFCS promoted food consumption, obesity, and impaired insulin sensitivity. Combining risk factors for the metabolic syndrome by feeding mice trans fats and HFCS induced histological features of NASH in the context of a metabolic profile similar to patients with this disease. Because dietary trans fats promoted liver steatosis and injury, their role in the epidemic of NASH needs further evaluation.

    Objective: To investigate the value of CT perfusion in the early diagnosis of hepatic diffuse disease. Methods: Fourteen male Wistar rats of control group and 14 of test group at stages of hepatitis, hepatic fibrosis, hepatic cirrhosis which were induced with diethylnitrosamine (DEN), were studied with CT perfusion respectively. CT perfusion data of different stages were compared and pathologic analysis were performed. Results: Density-time curves of CT perfusion were satisfactory and all perfusion data could be obtained. During the period of hepatitis developing into early stage of hepatic cirrhosis, hepatic artery flow (HAF) trended to increase in test group, mean transmit time (MTT) prolonged obviously, blood flow (BF) and volume (BV) declined. While in control group, HAF declined slightly, MTT, BV and BF increased. Statistic analysis showed the differences of HAF and MTT at different stages between control and test groups were significant (P<0.05 ); the differences of BV and BF between hepatitis and hepatic cirrhosis, hepatic fibrosis and early stage of hepatic cirrhosis in test group were significant (P<0.05), but no significant difference between hepatitis and hepatic fibrosis. The corresponding pathologic changes at stage of hepatitis was swelling of hepatic cells; sinusoids cap illarization and deposition of collagen in the extravascular Disse's spaces were the main changes relating to hepatic blood perfusion at stage of fibrosis and early stage of cirrhosis. Conclusion: The method of CT scan can reflect some changes of hepatic blood perfusion in rats with hepatitis, hepatic fibrosis and early stage of cirrhosis. The data of CT perfusion, especially the changes should be valuable for clinical early diagnosis, treatment and follow-up. (authors)

    2015-01-01

    Hepatic steatosis is defined as intrahepatic fat of at least 5% of liver weight. Simple accumulation of triacylglycerols in the liver could be hepatoprotective; however, prolonged hepatic lipid storage may lead to liver metabolic dysfunction, inflammation, and advanced forms of nonalcoholic fatty liver disease. Nonalcoholic hepatic steatosis is associated with obesity, type 2 diabetes, and dyslipidemia. Several mechanisms are involved in the accumulation of intrahepatic fat, including increased flux of fatty acids to the liver, increased de novo lipogenesis, and/or reduced clearance through β-oxidation or very-low-density lipoprotein secretion. This article summarizes the mechanisms involved in the accumulation of triacylglycerols in the liver, the clinical implications, and the prevention of hepatic steatosis, with a focus on the role of mitochondrial function and lifestyle modifications.

    Full Text Available Hepatitis B virus (HBV reactivation results from increased viral replication in inactive carriers or patients with prior infection with HBV. Reactivation may occur spontaneously or secondary to immunomodulating or immunosuppressive chemotherapy. Reactivation may manifest with no symptoms but on occasion results in acute or even severe acute hepatitis. Prevention is the best management approach, hence HBV screening using serology should be performed for all patients undergoing any immunomodulating, immunosuppressive or chemotherapeutic treatment. Antiviral prophylaxis has proven effective in inactive carriers and in some patients with former infection with HBV undergoing selected immunosuppressive therapies.La reactivación del virus de la hepatitis B se debe a un aumento de la replicación del virus en pacientes portadores inactivos o con infecciones pasadas de VHB. La reactivación puede producirse espontáneamente o de manera secundaria a tratamientos de quimioterapia, inmunomoduladores o inmunosupresores. La reactivación puede manifestarse de manera asintomática pero en algunos casos puede causar hepatitis agudas e incluso hepatitis agudas graves. El mejor tratamiento es la prevención por lo que se debe realizar un cribado del VHB mediante una serología a todos los pacientes que vayan a someterse a cualquier tratamiento inmunomodulador, de quimioterapia o inmunosupresor. El tratamiento profiláctico antiviral ha demostrado ser eficaz en los pacientes portadores inactivos y en algunos pacientes con infecciones pasadas de VHB sometidos a ciertos tratamientos inmunosupresores.

    Pomalidomide is an immunomodulatory drug and the dosage of 4 mg per day taken orally on days 1-21 of repeated 28-day cycles has been approved in the European Union and United States to treat patients with relapsed/refractory multiple myeloma. Because pomalidomide is extensively metabolized prior to excretion, a total of 32 subjects (8 healthy subjects in group 1; 8 subjects with severe hepatic impairment in group 2; 8 subjects with moderate hepatic impairment in group 3; and 8 subjects with mild hepatic impairment in group 4) were enrolled in a multicenter, open-label, single-dose study to assess the impact of hepatic impairment on pomalidomide exposure. Following administration of a single oral dose of 4-mg pomalidomide, the geometric mean ratios of pomalidomide total plasma exposures (AUC) were 171.5%, 157.5%, and 151.2% and the geometric mean ratios of pomalidomide plasma peak exposures (C max ) were 75.8%, 94.8%, and 94.2% for subjects with severe, moderate, or mild hepatic impairment, respectively, versus healthy subjects. Pomalidomide administered as a single oral 4-mg dose was safe and well tolerated by healthy subjects and subjects with severe, moderate, or mild hepatic impairment. Based on the pharmacokinetic results from this study, the pomalidomide prescribing information approved by the US Food and Drug Administration recommends for patients with mild or moderate hepatic impairment (Child-Pugh classes A or B), a 3-mg starting daily dose (25% dose reduction) and for patients with severe hepatic impairment (Child-Pugh class C), a 2-mg starting daily dose (50% dose reduction). © 2018 The Authors.

    1986-03-01

    Previous work has demonstrated that in vivo hepatic macrophage complement receptor clearance function is depressed following thermal injury. The present study was carried out to determine if complement receptor function depression is associated with other states of depressed host defense. Hepatic complement receptor clearance function was determined from the hepatic uptake of rat erythrocytes coated with antierythrocyte IgM (EIgM) in rats. Receptor function was determined following cannulation of a carotid artery, laparotomy plus enterotomy, hemorrhagic shock, trauma, thermal injury, acute bacteremia, acute endotoxemia, and injection of erythrocyte stroma, gelatinized lipid emulsion, or colloidal carbon. Hepatic uptake of EIgM was depressed following each of these experimental interventions except arterial cannulation. This effect was shown not to be due to a decrease in hepatic blood flow or depletion of complement and was therefore due to a depression in hepatic macrophage complement receptor clearance function. Thus, impairment of hepatic macrophage complement receptor function is associated with several states of depressed host defense.

    Hepatic trauma is a rare surgical emergency with significant morbidity and mortality. Extensive experience in liver surgery is a prerequisite for the management of these injuries. The medical records of 68 consecutive patients with hepatic trauma were retrospectively reviewed for the severity of liver injury, management, morbidity, mortality, and risk factors. Of the patients, 14 were treated conservatively and 52 surgically (24 suture/fibrin glue, 16 perihepatic packing, 11 resections, 1 liver transplantation). Two patients died just before emergency surgery could be performed. Overall mortality was 21% (14/68), and 13, 14, 6, 27, and 50% for types I, II, III, IV, and V injuries, respectively. Only nine deaths (all type IV and V) were liver related, while four were caused by extrahepatic injuries and one by concomitant liver cirrhosis. With respect to treatment, conservative management, suture, and resection had a low mortality of 0, 4, and 9%, respectively. In contrast, mortality was 47% in patients in whom only packing was performed (in severe injuries). Stepwise multivariate regression analysis proved prothrombin values 30, and transfusion requirements of more than 10 red packed cells to be significant risk factors for post-traumatic death. Type I-III hepatic injuries can safely be treated by conservative or simple surgical means. However, complex hepatic injuries (types IV and V) carry a significant mortality and may require hepatic surgery, including liver resection or even transplantation. Therefore, patients with severe hepatic injuries should be treated in a specialized institution.

    Full Text Available Background: At present, much attention is paid to genetic factors explaining the clinical course of chronic hepatitis C. Aim: To evaluate an association of the gene polymorphisms involved in the formation of endothelial dysfunction (NOS3 894G/T, CYBA 242C/T, MTHFR 677C/T and encoding components of the renin-angiotensin system (ATR1 1166A/C, AGT (-6G/T and 235M/T with development and severity of portal hypertension syndrome in patients with chronic hepatitis C. Materials and methods: 162 patients with chronic hepatitis C and HCV-related cirrhosis (114 women and 48 men were divided into the following groups: no portal hypertension (n = 98, "compensated" (n = 19 and "decompensated" (n = 45 portal hypertension. The gene polymorphisms were assessed by molecular genetic methods. Results: TT genotype of CYBA was more common in patients with portal hypertension than in those without (odds ratio (OR for TT = 3.59, p = 0.031. This difference becomes larger when comparing the decompensated portal hypertension group with the no portal hypertension group (OR TT = 5.46, p = 0.009. Other gene polymorphisms were not associated with development or decompensation of portal hypertension. Multivariate analysis of the impact of genetic, clinical and demographic factors showed that portal hypertension was associated primarily with patients age at the time of the study (Wald's х2 = 14.99 and with their body mass index (Wald's х2 = 4.35. After exclusion of these population-wide risk factors from the model, the development of portal hypertension correlated with the carriage of 235TT genotype of CYBA (Wald's х2 = 6.07, OR = 4.29 and (-6AA genotype AGT (Wald's х2 = 4.73, OR = 4.13, as well as with the lack of protective 235TT genotype AGT (Wald's х2 = 4.06, OR = 0.33. The combined effects of the studied gene polymorphisms on decompensation of the portal hypertension in patients with chronic HCV infection were similar. Conclusion: The development and increase in

    Hepatic and erythrocytic glutathione peroxidase activity, together with malondialdehyde levels, were determined as indicators of peroxidation in 83 patients from whom liver biopsies had been taken for diagnostic purposes. On histological study, the patients were classified into groups as minimal changes (including normal liver), steatosis, alcoholic hepatitis, hepatic cirrhosis, light to moderately active chronic hepatitis, and severe chronic active hepatitis. The glutathione peroxidase activity in erythrocytes showed no significant changes in any liver disease group. In the hepatic study, an increased activity was observed in steatosis with respect to the minimal changes group, this increased activity induced by the toxic agent in the initial stages of the alcoholic hepatic disease declining as the hepatic damage progressed. There was a negative correlation between the levels of hepatic malondialdehyde and hepatic glutathione peroxidase in subjects with minimal changes. This suggested the existence of an oxidative equilibrium in this group. This equilibrium is broken in the liver disease groups as was manifest in a positive correlation between malondialdehyde and glutathione peroxidase activity.

    The evaluation of the reserved hepatic function was performed by 99m Tc-galactosyl serum albumin ( 99m Tc-GSA) in 70 patients with hepatobiliary tumor. The dynamic study was performed to evaluate global reserved hepatic function following the intravenous bolus injection of 99m Tc-GSA, and the hepatic single photon emission computed tomography (SPECT) was obtained to assess the regional reserved hepatic function. The functional hepatic index (LHL 15 ) was derived from liver time-activity data, and it was compared with serum total-bilirubin level, serum albumin level and plasma disappearance rate of indocyanine green (ICG 15 ). In the patients with hepatocellular carcinoma, LHL 15 value agreed well with ICG 15 value, serum total-bilirubin level, and serum albumin level. Moderate or severe hepatic dysfunction was observed at 65.4% of these patients. In the patients with cholangiocellular carcinoma, a discrepancy of LHL 15 value and ICG 15 value was observed. Increment of the ICG 15 value was correlated with that of the serum total-bilirubin level, whereas the correlation was not observed between the LHL 15 value and the serum total-bilirubin level. These results indicate that 99m Tc-GSA scintigraphy can evaluate the reserved hepatic function without the embellishment of jaundice. This method is useful for assessing the global and regional reserved hepatic function. (author)

    time. The outcome after anti-HBe seroconversion depends on the degree of pre-existing liver damage and any subsequent HBV reactivation. Without pre-existing cirrhosis, there may be only slight fibrosis or mild chronic hepatitis, but with pre-existing cirrhosis, further complications may ensue. HBsAg-negative chronic hepatitis B is a phase of chronic HBV infection during which a mutation arises resulting in the inability of the virus to produce HBeAg. Such patients tend to have more severe liver disease and run a more rapidly progressive course. The annual probability of developing cirrhosis varies from 0.1 to 1.0% depending on the duration of HBV replication, the severity of disease and the presence of concomitant infections or drugs. The annual incidence of hepatic decompensation in HBV-related cirrhosis varies from 2 to 10% and in these patients the 5-year survival rate drops dramatically to 14-35%. The annual risk of developing HCC in patients with cirrhosis varies between 1 and 6%; the overall reported annual detection rate of HCC in surveillance studies, which included individuals with chronic hepatitis B and cirrhosis, is 0.8-4.1%. Chronic hepatitis B is not a static disease and the natural history of the disease is affected by both viral and host factors. The prognosis is poor with decompensated cirrhosis and effective treatment options are limited. Prevention of HBV infection thorough vaccination is still, therefore, the best strategy for decreasing the incidence of hepatitis B-associated cirrhosis and HCC.

  16. New Insights Into the Relationships Among Alcohol Consumption, Hepatocellular Carcinoma and Hepatitis C Virus Infection

    Full Text Available Context Viral hepatitis and the consumption of alcohol are recognized as important reasons for the development of liver disease throughout the world. It would also seem that chronic alcoholism causes more severe and rapid progression of liver disease in patients with chronic hepatitis C, leading to more frequent liver cirrhosis and hepatocellular carcinoma. Evidence Acquisition The data for this article were obtained through an initial Medline search and from the references of relevant articles, and used to provide updated information on the relationship between alcohol consumption and the hepatitis C virus. Results Excessive alcohol consumption among patients with chronic hepatitis C is likely to result in more severe hepatic injuries, promote pathologic progression to cirrhosis, and increase the risk of developing hepatocellular carcinoma. Although the exact mechanisms involved in the progression of chronic hepatitis C in alcoholic patients have not been definitely established, possible alcohol-induced enhancement of viral replication, iron overload, immunologic suppression, the role of NF-kappa B, and the signaling pathways involved in its activation, have been suggested. Significant correlations have been reported between hepatitis C virus RNA levels and the amount of alcohol consumed by an individual. Interferon therapy is less effective for alcohol patients, than non-alcoholic patients, even after a period of abstinence. The obtained data suggest that a hepatitis C virus infection is an important cofactor in the pathogenesis of liver disease among patients with an alcohol problem. Conclusions In light of a possible synergistic effect between alcohol and hepatitis C virus replication, total abstention ought to be recommended, and due to alcohol's inhibitory effect on interferon therapy, patients with alcohol problems should not be treated until they stop drinking.

    Animal models and studies in adults have demonstrated that copper restriction increases severity of liver injury in nonalcoholic fatty liver disease (NAFLD). This has not been studied in children. We aimed to determine if lower tissue copper is associated with increased NAFLD severity in children. This was a retrospective study of pediatric patients who had a liver biopsy including a hepatic copper quantitation. The primary outcome compared hepatic copper concentration in NAFLD versus non-NAFLD. Secondary outcomes compared hepatic copper levels against steatosis, fibrosis, lobular inflammation, balloon degeneration, and NAFLD activity score (NAS). The study analysis included 150 pediatric subjects (102 with NAFLD and 48 non-NAFLD). After adjusting for age, body mass index z score, gamma glutamyl transferase, alanine aminotransferase, and total bilirubin, NAFLD subjects had lower levels of hepatic copper than non-NAFLD (P = 0.005). In addition, tissue copper concentration decreased as steatosis severity increased (P steatosis alone. Further studies are needed to explore the relationship between copper levels and NAFLD progression.

    Suboptimal vitamin B2 status is encountered globally. Riboflavin deficiency depresses growth and results in a fatty liver. The underlying mechanisms remain to be established and an overview of molecular alterations is lacking. We investigated hepatic proteome changes induced by riboflavin deficiency to explain its effects on growth and hepatic lipid metabolism. In all, 360 1-d-old Pekin ducks were divided into three groups of 120 birds each, with twelve replicates and ten birds per replicate. For 21 d, the ducks were fed ad libitum a control diet (CAL), a riboflavin-deficient diet (RD) or were pair-fed with the control diet to the mean daily intake of the RD group (CPF). When comparing RD with CAL and CPF, growth depression, liver enlargement, liver lipid accumulation and enhanced liver SFA (C6 : 0, C12 : 0, C16 : 0, C18 : 0) were observed. In RD, thirty-two proteins were enhanced and thirty-one diminished (>1·5-fold) compared with CAL and CPF. Selected proteins were confirmed by Western blotting. The diminished proteins are mainly involved in fatty acid β-oxidation and the mitochondrial electron transport chain (ETC), whereas the enhanced proteins are mainly involved in TAG and cholesterol biosynthesis. RD causes liver lipid accumulation and growth depression probably by impairing fatty acid β-oxidation and ETC.

    Hepatic vena cava syndrome, also known as membranous obstruction of inferior vena cava (IVC), was considered a rare congenital disease and classified under Budd-Chiari syndrome. It is now recognized as a bacterial infection-induced disease related to poor hygiene. Localized thrombophlebitis of the IVC at the site close to hepatic vein outlets is the initial lesion which converts on resolution into stenosis or complete obstruction, the circulatory equilibrium being maintained by development of cavo-caval collateral anastomosis. These changes persist for the rest of the patient's life. The patient remains asymptomatic for a variable period until acute exacerbations occur, precipitated by bacterial infection, resulting in deposition of thrombi at the site of the lesion and endophlebitis in intrahepatic veins. Large thrombus close to hepatic vein outlets results in ascites from hepatic venous outflow obstruction, which is followed by development of venocentric cirrhosis. Endophlebitis of intrahepatic veins results in ischemic liver damage and development of segmental stenosis or membrane. Acute exacerbations are recognized clinically as intermittent jaundice and/or elevation of aminotransferase or ascites associated with neutrophil leukocytosis and elevation of C-reactive protein; sonologically, they are recognized as the presence of thrombi of different ages in IVC and thrombosis of intrahepatic veins. Development of liver cirrhosis and hepatocellular carcinoma is related to severity or frequency of acute exacerbations and not to duration or type of caval obstruction. Hepatic vena cava syndrome is a common co-morbid condition with other liver diseases in developing countries and it should be considered in differential diagnosis in patient with intermittent elevation serum bilirubin and or aminotransferase or development of ascites and cirrhosis. © 2017 The Japan Society of Hepatology.

    Objective: To investigate the incidence of HGV infection in patients with HBV hepatitis and any possible adverse effect of the superinfection. Methods: Serum HGV-RNA expression was examined with PCR in 1104 patients with HBV hepatitis and 251 controls. Results: The positive rate of HGV-RNA in HBV hepatitis patients was not significantly different from that in controls (3.17% vs 2.79%, P>0.05). Among the patients with HBV hepatitis, HGV-RNA positive rate in patients with chronic hepatitis was significantly higher than that in patients with acute hepatitis (4.78% vs 0.96, P<0.05). Conclusion: HGV infection might be presented as non-symptomatic carriers or other mild form of hepatitis. The incidence of HGV infection was not especially high in HBV hepatitis patients, however, concomitant HGV and HBV infection might predispose to development of chronicity. (authors)

It can be defined as a neuropsychiatric syndrome caused by portosystemic venous shunting, ranging from minimal to overt hepatic encephalopathy or coma. Its pathophysiology is still unclear, although increased levels of ammonia play a key role. Diagnosis of hepatic encephalopathy is currently based on specific tests evaluating the neuropsychiatric state of patients and their quality of life; the severity of hepatic encephalopathy is measured by the West Haven criteria. Treatment of hepatic encephalopathy consists of pharmacological and corrective measures, as well as nutritional interventions. Rifaximin received approval for the treatment of hepatic encephalopathy in 2010 because of its few side effects and pharmacological benefits. The aim of this work is to review the use and efficacy of rifaximin both in acute and long-term management of hepatic encephalopathy. Treatment of overt hepatic encephalopathy involves management of the acute episode as well as maintenance of remission in those patients who have previously experienced an episode, in order to improve their quality of life. The positive effect of rifaximin in reducing health care costs is also discussed.Keywords: acute hepatic encephalopathy, recurrent hepatic encephalopathy, rifaximin, lactulose, cost, health-related quality of life

  7. Hepatic Fatty Acid Oxidation Restrains Systemic Catabolism during Starvation

    2016-06-01

    Full Text Available The liver is critical for maintaining systemic energy balance during starvation. To understand the role of hepatic fatty acid β-oxidation on this process, we generated mice with a liver-specific knockout of carnitine palmitoyltransferase 2 (Cpt2L−/−, an obligate step in mitochondrial long-chain fatty acid β-oxidation. Fasting induced hepatic steatosis and serum dyslipidemia with an absence of circulating ketones, while blood glucose remained normal. Systemic energy homeostasis was largely maintained in fasting Cpt2L−/− mice by adaptations in hepatic and systemic oxidative gene expression mediated in part by Pparα target genes including procatabolic hepatokines Fgf21, Gdf15, and Igfbp1. Feeding a ketogenic diet to Cpt2L−/− mice resulted in severe hepatomegaly, liver damage, and death with a complete absence of adipose triglyceride stores. These data show that hepatic fatty acid oxidation is not required for survival during acute food deprivation but essential for constraining adipocyte lipolysis and regulating systemic catabolism when glucose is limiting.

    A review of published literature on viral hepatitis infections in Pakistan is presented. A total of 220 abstracts available in the Pakmedinet and Medline have been searched. All relevant articles were reviewed to determine the prevalence of hepatitis viral infections in Pakistan. Two hundred and three (203) relevant articles/abstracts including twenty nine supporting references are included in this review. Of the articles on prevalence of hepatitis infection, seven were related to Hepatitis A, fifteen to Hepatitis E while the remaining articles were on frequency of hepatitis B and C in different disease and healthy population groups. These included eight studies on healthy children, three on vertical transmission, nineteen on pregnant women, fifteen on healthy individuals, six on army recruits, thirty one on blood donors, thirteen on health care workers, five on unsafe injections, seventeen on high risk groups, five on patients with provisional diagnosis of hepatitis, thirty three on patients with chronic liver disease, four on genotypes of HBV and five on genotypes of HCV. This review highlights the lack of community-based epidemiological work as the number of subjects studied were predominantly patients, high risk groups and healthy blood donors. High level of Hepatitis A seroconversion was found in children and this viral infection accounts for almost 50%- 60% of all cases of acute viral hepatitis in children in Pakistan. Hepatitis E is endemic in the country affecting mostly the adult population and epidemic situations have been reported from many parts of the country. The mean results of HBsAg and Anti-HCV prevalence on the basis of data aggregated from several studies was calculated which shows 2.3% and 2.5% prevalence of HBsAg and Anti-HCV in children, 2.5% and 5.2% among pregnant women, 2.6% and 5.3% in general population, 3.5% and 3.1% in army recruits, 2.4% and 3.6% in blood donors, 6.0% and 5.4% in health care workers, 13.0% and 10.3% in high risk groups

    Acute viral hepatitis (AVH) is a major public health problem and is an important cause of morbidity and mortality. The aim of the present study is to determine the prevalence of hepatitis A virus (HAV), hepatitis B virus (HBV), hepatitis C virus (HCV), hepatitis D virus (HDV) and hepatitis E virus (HEV) as causes of AVH in a tertiary care hospital of North India. Blood samples and clinical information was collected from cases of AVH referred to the Grade I viral diagnostic laboratory over a 1-year period. Samples were tested for hepatitis B surface antigen, anti-HCV total antibodies, anti-HAV immunoglobulin M (IgM) and anti-HEV IgM by the enzyme-linked immunosorbent assay. PCR for nucleic acid detection of HBV and HCV was also carried out. Those positive for HBV infection were tested for anti-HDV antibodies. Fisher's exact test was used and a P hepatitis cases, 62 (23.22%) patients presented as acute hepatic failure. HAV (26.96%) was identified as the most common cause of acute hepatitis followed by HEV (17.97%), HBV (16.10%) and HCV (11.98%). Co-infections with more than one virus were present in 34 cases; HAV-HEV co-infection being the most common. HEV was the most important cause of acute hepatic failure followed by co-infection with HAV and HEV. An indication towards epidemiological shift of HAV infection from children to adults with a rise in HAV prevalence was seen. To the best of our knowledge, this is the first report indicating epidemiological shift of HAV in Uttar Pradesh.

    Extracellular adenosine regulates inflammatory responses via the A2A adenosine receptor (A2AR). A2AR deficiency results in much exaggerated acute hepatitis, indicating nonredundancy of adenosine-A2AR pathway in inhibiting immune activation. To identify a critical target of immunoregulatory effect of extracellular adenosine, we focused on NKT cells, which play an indispensable role in hepatitis. An A2AR agonist abolished NKT-cell-dependent induction of acute hepatitis by concanavalin A (Con A) or α-galactosylceramide in mice, corresponding to downregulation of activation markers and cytokines in NKT cells and of NK-cell co-activation. These results show that A2AR signaling can downregulate NKT-cell activation and suppress NKT-cell-triggered inflammatory responses. Next, we hypothesized that NKT cells might be under physiological control of the adenosine-A2AR pathway. Indeed, both Con A and α-galactosylceramide induced more severe hepatitis in A2AR-deficient mice than in WT controls. Transfer of A2AR-deficient NKT cells into A2AR-expressing recipients resulted in exaggeration of Con A-induced liver damage, suggesting that NKT-cell activation is controlled by endogenous adenosine via A2AR, and this physiological regulatory mechanism of NKT cells is critical in the control of tissue-damaging inflammation. The current study suggests the possibility to manipulate NKT-cell activity in inflammatory disorders through intervention to the adenosine-A2AR pathway. © 2014 WILEY-VCH Verlag GmbH & Co.

    A 16-year-old adolescent male sustained combined injuries to the tricuspid valve and liver. This injury is exceptional due to the mechanism and the circumstances in which it took place: a flying pumpkin thrown from a sport utility vehicle. An echocardiogram demonstrated a flail chordal apparatus associated with the posterior leaflet of the tricuspid valve, creating substrate for severe tricuspid regurgitation with preserved right heart function. He was treated with non-operative management for the liver injury; he remained hemodynamically stable and was discharged home. He underwent successful repair of the tricuspid valve 17 days following the initial injury necessitating systemic anticoagulation and was discharged home two days later. The patient recovered fully without residual valvular pathology or hepatic sequelae. Copyright © 2013 Elsevier Inc. All rights reserved.

    Purpose To evaluate the diagnostic performance and examination success rate of magnetic resonance (MR) elastography and vibration-controlled transient elastography (VCTE) in the detection of hepatic fibrosis in patients with severe to morbid obesity. Materials and Methods This prospective and HIPAA-compliant study was approved by the institutional review board. A total of 111 patients (71 women, 40 men) participated. Written informed consent was obtained from all patients. Patients underwent MR elastography with two readers and VCTE with three observers to acquire liver stiffness measurements for liver fibrosis assessment. The results were compared with those from liver biopsy. Each pathology specimen was evaluated by two hepatopathologists according to the METAVIR scoring system or Brunt classification when appropriate. All imaging observers were blinded to the biopsy results, and all hepatopathologists were blinded to the imaging results. Examination success rate, interobserver agreement, and diagnostic accuracy for fibrosis detection were assessed. Results In this obese patient population (mean body mass index = 40.3 kg/m 2 ; 95% confidence interval [CI]: 38.7 kg/m 2 , 41.8 kg/m 2 ]), the examination success rate was 95.8% (92 of 96 patients) for MR elastography and 81.3% (78 of 96 patients) or 88.5% (85 of 96 patients) for VCTE. Interobserver agreement was higher with MR elastography than with biopsy (intraclass correlation coefficient, 0.95 vs 0.89). In patients with successful MR elastography and VCTE examinations (excluding unreliable VCTE examinations), both MR elastography and VCTE had excellent diagnostic accuracy in the detection of clinically significant hepatic fibrosis (stage F2-F4) (mean area under the curve: 0.93 [95% CI: 0.85, 0.97] vs 0.91 [95% CI: 0.83, 0.96]; P = .551). Conclusion In this obese patient population, both MR elastography and VCTE had excellent diagnostic performance for assessing hepatic fibrosis; MR elastography was more

    To evaluate and compare MR and CT in diagnosis of acute traumatic hepatic laceration, ten patients with acute hepatic rupture underwent CT scan and/or MRI in the first 24 hours after injury. The injury was graded as mild ( 50% of one lobe). In the first 24 hours after injury, 33.3% (3/9) and 28.6%(2/7) of the hepatic injury demonstrated isodensity and isointensity on plain CT scan and T 1 -weighted images. All the lesions (100%) were clearly identified as marked hyperintensity on T 2 -weighted images. On T 2 WI, T 1 WI and non-contrast CT, 100%, 57.1% and 55.6% of the acute hepatic injuries could be graded respectively. Delayed complications occurred in four patients with deep hepatic injury about 1 to 3 weeks after injury. T 2 -weighted MR imaging is more sensitive and useful for detection of the type and severity of acute hepatic rupture. Follow-up MRI or CT within the first few weeks after injury is needed in patients with deep hepatic injury for detection of delayed complications

    Immunological mediated hepatitis can be initiated by bacterial product; Lipopolysaccharide (LPS). The later is increased during severe infection, bacterial overgrowth or translocation. LPS stimulates Kupffer cells. Activation of the kupffer cells contributes to the onset of liver injuries by producing and releasing cytotoxic agents, inflammatory cytokines and reactive oxygen species. In the present study, L-carnitine, a natural antioxidant and immunoprotective agent, is used to protect against LPS-induced hepatitis. Liver content of glutathione (GSH), malondialdehyde (MDA), nitric oxide (NO) and the DNA adduct 8-hydroxydeoxyguanosine (8-HDG) are estimated. Serum activity of liver enzymes ALT, AST, and Gamma-GT, in addition to IL2 level are also estimated. Moreover, liver histopathological changes are determined. Results revealed that LPS (5mg/kg once i.p) significantly increased 8-HDG, MDA, NO and depleted GSH in the liver of the treated rats. It also increased serum IL2 and activity of all the estimated liver enzyme markers indicating massive hepatic cellular damage as also shown as a necrotic damage in liver histological sections. LCR administered (500mg/kg) 3h before LPS protected against LPS-induced lethality by 100%. LCR also prevented the increase in liver content of 8-HDG, MDA and NO. It reduced the depleted GSH and prevented the necrotic damage in the liver tissue as shown by normalization of ALT, AST and Gamma-Gt as well as IL2 and a remarkable improvement in liver histology. These data suggest that LCr could be used as an adjuvant therapy in severely infected and specific patients to counteract LPS-induced liver hepatitis. (author)

    A description is presented of a radioimmunoassay designed to prove the presence of the antibody against the hepatitis A virus (HA Ab, anti-Ha) using an Abbott HAVAB set. This proof as well as the proof of the antibody against the nucleus of the hepatitis B virus is based on competition between a normal antibody against hepatitis A virus and a 125 I-labelled antibody for the binding sites of a specific antigen spread all over the surface of a tiny ball; this is then indirect proof of the antibody under investigation. The method is described of reading the results from the number of impulses per 60 seconds: the higher the titre of the antibody against the hepatitis A virus in the serum examined, the lower the activity of the specimen concerned. The rate is reported of incidence of the antibody against the hepatitis A virus in a total of 68 convalescents after hepatitis A; the antibody was found in 94.1%. The immunoglobulin made from the convalescents' plasma showed the presence of antibodies in dilutions as high as 1:250 000 while the comparable ratio for normal immunoglobulin Norga was only 1:2500. Differences are discussed in the time incidence of the antibodies against the hepatitis A virus, the antibodies against the surface antigen of hepatitis B, and the antibody against the nucleus of the hepatitis V virus.

    This prospective study was designed to investigate the utility of sonography in establishing severity of liver cirrhosis as compared with Child class in clinical creteria. Seventy-our consecutive patients with liver cirrhosis were examined with sonography. This study included 50 males and 24 females, aged 35 to 72 years (mean ; 51) The number of patients in child A,B, and C group was 30,29,15 respectively. Sonographic features evaluated were hepatic parenchymal echo pattern, presence of nodularity of hepatic surface, degree of hepatic sonic attenuation,degree of obliteration of wall echo of the intrahepatic portal vein, size of the main portal vein, thickness of the gallbladder wall, size of the spleen, and presence of ascites. Each sonographic features was graded from 0 to depending upon the degree of severity, and was correlated with Child class of liver cirrhosis. Hepatic parenchymal echo pattern, presence of nodularity of hepatic surface, thickness of gallbladder wall, and presence of ascites were correlated well with Child class (p 0.05). In conclusion, these results indicate that careful evaluation of sonographic features are helpful in predicting severity of liver cirrhosis

    Full Text Available OBJECTIVE: Transfusion transmitted hepatitis has been a severe problem in Turkey in pediatric cancer patients and in chronic congenital anemia. The aim of the present study was to investigate the prevalence of hepatitis B, hepatitis C and human immunodeficiency virus infections in these patients in a University Hospital. METHODS: Multi-transfused 66 children (59 acute leukemia, 6 thalassemia major, 1 severe hereditary spherocytosis diagnosed and followed-up between May, 2000 and December, 2006 were evaluated. Screening of all the patients for HbsAg, anti-HBs, anti-HBc, anti-HCV and anti-HIV was performed at presentation and during the last follow-up. Serologic studies of leukemic patients were also repeated at the end of the chemotherapy. Hepatitis B vaccination was administered to unvaccinated patients with anemia. All blood products were provided by Blood Bank of the Center. RESULTS: No patient was found HBsAg, anti-HCV or anti-HIV positive at diagnosis and at the end of the therapy. There was history of hepatitis B vaccination in only 42% of the patients at diagnosis due to administration of this vaccine to newborns since 1998. At the beginning of the study, 45 % (n=27 of the leukemic patients were immune for hepatitis B, but after completion of the intensive chemotherapy seropositivity persisted in only 28.8 % (n=17. CONCLUSION: Transmission of these viruses is no longer a real problem even in multitransfused immunosuppressed children in Pediatric Hematology Units as a result of the improvements in screening of voluntary blood donors, administration of disposable material in clinics and vaccination by hepatitis B.

    Non-operative management of isolated blunt hepatic trauma is recommended except when hemodynamic instability requires immediate laparotomy. Hepatic artery angioembolization is increasingly used for hepatic injuries with ongoing bleeding as demonstrated by contrast extravasation on the CT scan. It is used primarily or after laparotomy to control ongoing hemorrhage. Hepatic angioembolization as part of multimodality management of hepatic trauma is reported mainly in adults, with few pediatric case reports. We describe our institution experience with primary pediatric hepatic angioembolization and review the literature with regard to indications and complications. Two cases (3 and 8 years old), with high-grade blunt hepatic injuries with contrast extravasation on the CT scan were successfully managed by emergency primary hepatic angioembolization with minimal morbidity and avoided laparotomy. To date, the only reports of pediatric hepatic angioembolization for trauma are 5 cases for acute bleeding and 15 delayed cases for pseudoaneurysm. The role of hepatic angioembolization in the presence of an arterial blush on CT in adults is accepted, but contested in a pediatric series, despite higher transfusion rate and mortality rate. We propose that hepatic angioembolization should be considered adjunct treatment, in lieu of, or in addition to emergency laparotomy for hemostasis in pediatric blunt hepatic injury.

  6. Current pathogenetic aspects of hepatic encephalopathy and noncirrhotic hyperammonemic encephalopathy.

    Science.gov (United States)

    Cichoż-Lach, Halina; Michalak, Agata

    2013-01-07

    Hepatic encephalopathy is a medical phenomenon that is described as a neuropsychiatric manifestation of chronic or acute liver disease that is characterized by psychomotor, intellectual and cognitive abnormalities with emotional/affective and behavioral disturbances. This article focuses on the underlying mechanisms of the condition and the differences between hepatic encephalopathy and noncirrhotic hyperammonemic encephalopathy. Hepatic encephalopathy is a serious condition that can cause neurological death with brain edema and intracranial hypertension. It is assumed that approximately 60%-80% of patients with liver cirrhosis develop hepatic encephalopathy. This review explores the complex mechanisms that lead to hepatic encephalopathy. However, noncirrhotic hyperammonemic encephalopathy is not associated with hepatic diseases and has a completely different etiology. Noncirrhotic hyperammonemic encephalopathy is a severe occurrence that is connected with multiple pathogeneses.

    Objective: To study severe and rare complications of transarterial chemoembolization (TACE) for liver cancer. Methods: Clinical records of severe and rare complications following TACE in 1348 cases of liver cancer from January 1997 to February 2004 were studied retrospectively. Results: A total of 2012 TACE procedures were performed for 1348 patients. There were 3 cases of spontaneous rupture of liver cancer, 1 case of perforation of duodenum, 3 cases of liver abscess (1 of them was associated with sepsis), 1 case of pulmonary embolism, 1 case of spasm of the hepatic artery, 40 cases of hepatic artery occlusion, 3 cases of femoral nerve injury, 1 case of bilioma and 1 case of acute renal failure. Conclusion: Although the severe complications of TACE are rare, the procedure should be done cautiously including super selection of hepatic artery, slow infusion of lipiodol, careful postoperative observations and early detection and management of complications

    In April 2007, Panama introduced Hepatitis A universal vaccination using a two-dose schedule (Havrix(®)junior; GSK Vaccines, Belgium). We assessed the impact of this hepatitis A vaccine three years after it was recommended for universal mass vaccination in Panama. Hepatitis A vaccination impact was assessed using two different approaches. The first approach used retrospective data (incidence and number of cases for all age groups), collected from the passive surveillance of the Epidemiologic Surveillance System of the Ministry of Health of hepatitis A and unspecified hepatitis before (2000-2006) and after (2008-2010) introduction of hepatitis A vaccine. The second approach was a prospective hospital-based active surveillance for hepatitis cases conducted in subjects (0-14 years) during 2009-2011 at three sentinel hospitals in Panama. Overall, the annual incidence of hepatitis A and unspecified hepatitis in 2008, 2009 and 2010 were 13.1, 7.9 and 3.7 per 100,000 subjects, lower than the baseline incidence of 51.1 per 100,000 subjects. In comparison to the mean baseline period (2000-2006), there was an 82% mean reduction in the overall hepatitis-related outcomes (hepatitis A and unspecified hepatitis) after vaccine introduction (2008-2010) in all age groups. In the hospital-based surveillance (2009-2011), of the 42 probable viral hepatitis A cases, nine cases were confirmed as acute hepatitis A (8 in 2009, 1 in 2010). Of these confirmed cases, two belonged to the targeted vaccine group (1-4 years) but were not vaccinated. Our study suggests that the introduction of two-dose hepatitis A vaccines in Panama has contributed to the reduction in the incidence of overall hepatitis-related outcomes for all age groups, suggesting herd protection. Additional monitoring is required to document a sustained long-term effect. Copyright © 2015 The Authors. Published by Elsevier Ltd.. All rights reserved.

  11. Hepatic abscess linked to oral actinomycetes: a case report.

    De Farias, Deborah G

    2015-01-01

    Organ abscesses are rare, life-threatening complications that can be caused by bacteremia from oral infections. Metastatic infection is a well-established concept. Dental and periapical infections can cause infections in distant organs and tissues. The frequency of these systemic infections and systemic diseases is open to debate, as some patients are more susceptible to infections than others. This article presents the case report of a 52-year-old woman who was hospitalized with a hepatic abscess after a routine periodontal maintenance procedure. The patient had poor oral health, involving several nonrestorable teeth, multiple failed endodontic treatments, and asymptomatic chronic periapical pathologies. Her dental history included previous diagnoses of moderate generalized chronic periodontitis and advanced localized periodontitis. It was possible that bacteremia developed during her most recent dental treatment, leading to the hepatic abscess. Systemic antibiotic therapy, drainage of the hepatic abscess, and oral rehabilitation resulted in complete recovery.

    Hepatic veno-occlusive disease, or sinusoidal obstruction syndrome (VOD/SOS), is a serious and potentially fatal complication of conditioning for hematopoietic stem cell transplantation (HSCT) or of chemotherapy regimens alone. Defibrotide is a complex mixture of single-stranded polydeoxyribonucleotides that is approved in the United States for treating hepatic VOD/SOS with renal or pulmonary dysfunction post-HSCT and in the European Union, Israel, and South Korea for treating severe hepatic VOD/SOS post-HSCT. Defibrotide was previously available in the United States as an investigational drug through a treatment protocol (treatment IND) study. Interim results of that large, treatment IND study of patients with VOD/SOS and with or without multiorgan dysfunction (MOD; also known as multiorgan failure) are presented here. Defibrotide was administered i.v. at 6.25 mg/kg every 6 hours (25 mg/kg/day), with a recommended treatment duration of at least 21 days. Enrolled patients (n = 681) were diagnosed with VOD/SOS based on Baltimore or modified Seattle criteria or liver biopsy analysis. Among the 573 HSCT recipients, 288 (50.3%; 95% confidence interval [CI], 46.2% to 54.4%) were alive at day +100 post-HSCT. Day +100 survival for the pediatric (≤16 years) and adult (>16 years) subgroups was 54.5% (95% CI, 49.1% to 60.0%; n = 174 of 319) and 44.9% (95% CI, 38.8% to 51.0%; n = 114 of 254), respectively. In the MOD subgroup, 159 of 351 patients (45.3%; 95% CI, 40.1% to 50.5%) of patients were alive at day +100 post-HSCT. Treatment with defibrotide was generally well tolerated, and drug-related toxicities were consistent with previous studies. Adverse events were reported in 69.6% of safety-evaluable patients (399 of 573). Other than VOD/SOS and associated MOD symptoms, the most commonly reported treatment-emergent adverse event was hypotension (13.8%). Day +100 survival results observed in this trial were consistent with results seen in previous trials of

  15. [Characteristic situation on prevention of nosocomial infection in the hospital for the severely multi-disabled--experiences in care and treatment of 4 kinds of viral hepatitis].

    1997-12-01

    We experienced Hepatitis A, B, C and fulminant hepatitis due to Herpes simplex virus type 1 (HSV-1) in our hospital for the severely multi-disabled (SMD) who had both severe motor and intellectual disabilities, and some of whom might be further complicated by blindness and/or deafness. In this hospital, 100 SMDs are hospitalized. Case 1: The disabled, 25 year old male, was transmitted Hepatitis A from a nurse. Case 2: The disabled, 60 year old female carrier of Hepatitis B virus (HBV) who has been cared for more than 10 years. Case 3: The disabled, 46 year old male carrier of Hepatitis C virus (HCV) (RNA type 3), has been cared for more than 4 years. Case 4: The disabled, 39 year old male, had a fever of 39 degrees C for 9 days and suddenly died. He was diagnosed as fulminant hepatitis due to HSV-1 by necropsy. The hospitals for SMD are characteristic in prevention of nosocomial infections; 1) The disabled infected is not aware of the fact that he or she is the source of infection and that the other disabled living with him or her are in risk of infection, because of their severe mental condition. 2) All of the disabled need complete or incomplete helps for activities of daily life (ADL), so that the disabled who is the carrier of some pathogen constantly gives risk of infection to staffs, including medical staffs (doctor, nurse and therapist), psychologist and helpers by bloody secretion from wounds, saliva, urine, feces as well as menstrual blood. 3) If a carrier of some pathogen is hospitalized, the staffs should serve under risk of infection involving blood-mediated infectious disease for many years, because SMDs are permitted lifelong stay in the hospitals for SMD, which also play a role of care house or institution, by public expense in Japan. In case of an outbreak of Hepatitis A, nosocomial infection ended in the original case (a nurse), another nurse and a case of the disabled by general treatment and care against communicable diseases of the digestive

    1996-02-01

    The evaluation of the reserved hepatic function was performed by {sup 99m}Tc-galactosyl serum albumin ({sup 99m}Tc-GSA) in 70 patients with hepatobiliary tumor. The dynamic study was performed to evaluate global reserved hepatic function following the intravenous bolus injection of {sup 99m}Tc-GSA, and the hepatic single photon emission computed tomography (SPECT) was obtained to assess the regional reserved hepatic function. The functional hepatic index (LHL{sub 15}) was derived from liver time-activity data, and it was compared with serum total-bilirubin level, serum albumin level and plasma disappearance rate of indocyanine green (ICG{sub 15}). In the patients with hepatocellular carcinoma, LHL{sub 15} value agreed well with ICG{sub 15} value, serum total-bilirubin level, and serum albumin level. Moderate or severe hepatic dysfunction was observed at 65.4% of these patients. In the patients with cholangiocellular carcinoma, a discrepancy of LHL{sub 15} value and ICG{sub 15} value was observed. Increment of the ICG{sub 15} value was correlated with that of the serum total-bilirubin level, whereas the correlation was not observed between the LHL{sub 15} value and the serum total-bilirubin level. These results indicate that {sup 99m}Tc-GSA scintigraphy can evaluate the reserved hepatic function without the embellishment of jaundice. This method is useful for assessing the global and regional reserved hepatic function. (author).

    2009-01-01

    Objective: To investigate the variations of hepatic artery and its extrahepatic arteries on hepatic arteriogram and to provide benefit for transhepatic arterical chemoemblization. Methods: The hepatic arteriograms of 200 cases with unresectable hepatic malignant tumor before interventional therapy were analysed. Two interventional radiologists in common reviewed the incidences of various types according to Michels' classification, the absence of proper hepatic artery, and the variations of extrahepatic arteries originating from hepatic artery. Results: The most common hepatic artery variation was Michels type III(n=17,8.5%), followed by type II(n=10,5.0%) and V(n=9,4.5%). Proper hepatic absence was found in 25 cases and appeared as 5 subtypes. 5 kinds of extrahepatic arteries were found. The most common extrahepatic artery was the right gastric artery (n=156,78.0%), followed by cystic artery (n=126,63.0%), accessory left gastric artery (n=19,9.5%), the hepatic falciform artery (n=5,2.5%), and accessory left inferior phrenic artery (n=4,2.0%). Conclusion: There are some other variations of hepatic artery beside Michels' classification,and there are many variations of extrahepatic arteries originating from hepatic artery, it is important to assure interventional therapy effect for hepatic cancer and prevent complication.

    The hemodynamic changes in hepatic vascular structures of hepatosteatosis patients were examined using Doppler ultrasonography. Ninety hepatosteatosis patients, classified as mild, moderate or severe, and 30 healthy volunteers were included in this 120-person study. The height, weight, liver size, blood lipids and blood liver function tests of the subjects were measured. Those values were compared in the patient and control groups. In the patient and control groups, color duplex Doppler ultrasonography was used to examine portal vein peak velocity, portal vein flow volume, hepatic artery resistive index (RI), hepatic artery pulsatility index (PI) and hepatic artery flow volume. Similarly to the degree of hepatosteatosis, increases in body mass index, liver size, liver enzyme levels and blood lipid levels were statistically significant (p<0.05). While the difference in portal vein peak velocity in the hepatosteatosis and control groups was not statistically significant, there was an increasing reduction in the degree of steatosis (p>0.05). As the degree of hepatosteatosis increased, there was a reduction in hepatic artery flow volume, portal vein flow volume and total flow volume that was not statistically significant. In the mild hepatosteatosis group, hepatic artery RI and PI values were statistically significantly lower than in the other groups (p<0.05). In the severe hepatosteatosis group, although the hepatic artery RI and PI values were not statistically significant, there was a minimal increase compared to the other groups. It is believed that those results were caused by a reduction in liver compliance and hepatic vascular compliance, in addition to resistance increase in vascular structures

  3. Immunological and molecular epidemiological characteristics of acute and fulminant viral hepatitis A

    2011-01-01

    Background Hepatitis A virus is an infection of liver; it is hyperendemic in vast areas of the world including India. In most cases it causes an acute self limited illness but rarely fulminant. There is growing concern about change in pattern from asymptomatic childhood infection to an increased incidence of symptomatic disease in the adult population. Objective In-depth analysis of immunological, viral quantification and genotype of acute and fulminant hepatitis A virus. Methods Serum samples obtained from 1009 cases of suspected acute viral hepatitis was employed for different biochemical and serological examination. RNA was extracted from blood serum, reverse transcribed into cDNA and amplified using nested PCR for viral quantification, sequencing and genotyping. Immunological cell count from freshly collected whole blood was carried out by fluorescence activated cell sorter. Results Fulminant hepatitis A was mostly detected with other hepatic viruses. CD8+ T cells count increases in fulminant hepatitis to a significantly high level (P = 0.005) compared to normal healthy control. The immunological helper/suppressor (CD4+/CD8+) ratio of fulminant hepatitis was significantly lower compared to acute cases. The serologically positive patients were confirmed by RT-PCR and total of 72 (69.2%) were quantified and sequenced. The average quantitative viral load of fulminant cases was significantly higher (P hepatitis A. Phylogenetic analysis of acute and fulminant hepatitis A confirmed genotypes IIIA as predominant against IA with no preference of disease severity. PMID:21605420

    Hepatitis B vaccination was introduced into the Expanded Program of Immunization in Colombia in 1992, in response to WHO recommendations on hepatitis B immunization. Colombia is a low endemic country for Hepatitis B virus infection (HBV) but it has several high endemic areas like the Amazon basin where more than 70 % of adults had been infected. A cross- sectional study was carried out in three rural areas of the Colombian Amazon to evaluate compliance with the recommended schedule for hepatitis B vaccine in Colombian children (one monovalent dose given in the first 24 h after birth + 3 doses of a pentavalent containing Hepatitis B. (DPT + Hib + Hep B). A household survey was conducted in order to collect vaccination data from children aged from 6 months to studied, 79 % received a monovalent dose of hepatitis B vaccine, but only 30.7 % were vaccinated in the first 24 h after birth. This proportion did not increase by age or subsequent birth cohorts. Coverage with three doses of a DTP-Hib-HepB vaccine was 98 %, but most children did not receive them according to the recommended schedule. Being born in a health facility was the strongest predictor of receiving a timely birth dose. This study suggests that more focused strategies on improving compliance with hepatitis B birth dose should be implemented in rural areas of the Amazon, if elimination of perinatal transmission of HBV is to be achieved. Increasing the proportion of newborns delivered at health facilities should be one of the priorities to reach that goal.

    Full Text Available Introduction. Extra-hepatic portal vein obstruction (EHPVO is one of the most often causes of portal hypertension in children. Objective. Establishing the importance of shunt surgery in combination with partial spleen resection in selected pediatric patients with EHPVO, enormous splenomegaly and severe hypersplenism. Methods. Distal splenorenal shunt (DSRS with partial spleen resection was performed in 22 children age from 2 to 17 years with EHPVO. Indications for surgery were pain and abdominal discomfort caused by spleen enlargement, as well as symptomatic hypersplenism with leucopenia, thrombocytopenia and anemia. The partial spleen resection was performed by ligation of blood vessels to caudal two thirds of the spleen. After ischemic parenchymal demarcation transection with electrocautery LigaSure was performed with preservation of 20-30% of spleen tissue, and then Warren DSRS was created. Platelet and leucocytes counts and liver function tests were obtained before, one month and one year after surgery. Growth was assessed with SD scores (Z scores for height, weight and body mass index at the time of surgery and one year later. Results. In all patients postoperative period was without significant complications. Platelets and leucocytes counts were normalized. Patency rate of shunts was 100%. Two significant shunts stenosis were observed and successfully treated with percutaneous angioplasty. During the follow-up period (1 to 9 years all patients were asymptomatic, with improved quality of life and growth. Conclusion. Results of our study indicate that shunt surgery with a partial spleen resection is an effective and safe procedure for patients with enormous splenomegaly and severe hypersplenism caused by EHPVO.

    Objective: To investigate the changes of serum levels of collagen type IV(IV-C), procollagen type III (PC III), hyaluronic acid (HA), laminin (LN) and prolidase (PLD) and their relationship with hepatic fibrosis in patients with B hepatitis of different types. Methods: Serum levels of IV-C, PC III, HA, LN and PLD were measured with RIA in 39 controls and 103 patients with HBV infection of various types (including acute hepatitis AH n=19, chronic persistent hepatitis CPH n=29, Chronic active hepatitis CAH n=25 and liver cirrhosis LH n=30. Degree of hepatic fibrosis (Grade 0-4) was ascertained with liver biopsy in 35 patients (CAH16, LC19) and correlationship with the corresponding levels of these 5 serum markers was steadied. Results: 1) Serum levels of IV-C, PC III, HA, LN and PLD were significantly higher in patients with CAH and LC than those in other patients and controls (P 0.05). 3) Serum levels of these markers were all positively correlated with the degree of hepatic fibrosis noted in the biopsy specimens obtained from patients with CAH (n=16) and LC (n=19) (r=+0.64 - + 0.89, P<0.01). Conclusion: Serum levels of these markers could reflect the degree of hepatic fibrosis and severity of liver damage; determination of which was of diagnostic and even prognostic value. HA and LN appeared to be better correlated with degree of hepatic fibrosis than the remaining three markers did. (authors)

    Hepatitis E was identified as an epidemic of non-A, non-B hepatitis from Kashmir, India in 1978. Hepatitis E virus (HEV), the etiological agent is the sole member of family Hepeviridae. The virus has marked heterogeneity and infects many animals like bats, camel, chicken, deer, boar, mongoose, pigs, rats, rabbit and cutthroat trout. Hepatitis E is a disease with a major global impact and has two distinct epidemiological patterns. Hepatitis E is an imperative health issue in developing nations, transmitted through sullied water and happens most every now in young adults. The disease is particularly severe during pregnancy and in people with underlying liver cirrhosis. Autochthonous hepatitis E is increasingly recognized in developed countries. The virus infects domestic pigs, wild boar and Sika deer in these countries. HEV infections in humans occur by eating the undercooked game flesh, raw liver from supermarkets and Figatelli sausages. Blood transfusion-associated HEV infections occur in many countries and screening of donors for HEV RNA is under consideration. Hepatitis E causes a number of extrahepatic diseases, including a wide spectrum of neurological syndromes. HEV genotype 3 causes prolonged viremia, chronic hepatitis, liver fibrosis and cirrhosis in organ transplant patients. The virus is amenable to ribavirin monotherapy and most patients clear the virus in a few weeks. Hepatitis E vaccine -239, marketed in China, has shown high efficacy with sustained protection for over four years.

    Renewed interest in hepatic artery infusion has been stimulated by the development of a totally implantable pump which eliminates many of the problems encountered by the external pumps and catheters. As the potential benefit of hepatic artery infusion would be greater if either all gross disease were removed by prior resection, or alternatively, if non-resectable disease were irradiated in conjunction with hepatic artery infusion, the authors initiated a phase I-II trial to evaluate combined modality therapy

    Full Text Available The article presents an analysis of the first clinical cases of acute hepatitis E autochtonic on the territory of the Kirov region. HEV-infection was diagnosed in 76 year old male, not to travel outside the region and the country for a long time, eat a lot of fresh fruit. A feature of the disease in non-endemic region was: severe course of hepatitis E in the elderly, with the development of clinic of acute liver failure and encephalopathy, the presence of the expressed syndrome cytolysis, cholestasis, hepatic-cell failure.Timely treatment of a patient for medical care, the lack of severe somatic diseases, chronic liver disease and adequate pathogenetic therapy helped to keep the patient’s life. In deciphering undifferentiated acute hepatitis in the elderly should be included in the scheme of examination and determination HEV RNA, a/HEV IgM and G.

  11. Hepatitis E in liver biopsies from patients with acute hepatitis of clinically unexplained origin.

    Full Text Available Hepatitis E virus (HEV is a small RNA virus and the infectious agent of hepatitis E that occurs worldwide either as epidemics in Asia caused by genotype 1 and 2 or as sporadic disease in industrialized countries induced by genotype 3 and 4. The frequency might be underestimated in central Europe as a cause of acute hepatitis. Therefore, we analyzed on liver biopsies, if cases of acute hepatitis with clinically unknown or obscure diagnosis were actually caused by the infection with HEV.We included 221 liver biopsies retrieved from the files of the institute of pathology during the years 2000 till 2010 that were taken from patients with acute hepatitis of obscure or doubtful diagnosis. From all biopsies RNA was extracted, prepared, and subjected to RT-PCR with specific primers. Amplified RNA was detected in 7 patients, sequenced and the genotype 3 could be determined in four of the seven of positive specimens from 221 samples. Histopathology of the biopsies revealed a classic acute hepatitis with cholestatic features and in some cases confluent necrosis in zone 3. Histology in a cohort of matched patients was less severe and showed more eosinophils. The analysis of the immune response by subtyping of liver infiltrating lymphocytes showed circumstantial evidence of adaptive immune reaction with CD 8 positive CTLs being the dominant lymphocyte population.In conclusion, in doubtful cases of acute hepatitis of unknown origine hepatitis E virus infection should be considered as etiology in central Europe. We demonstrate for the first time that the diagnosis can be made in paraffin-embedded liver biopsies reliably when no serum is available and also the genotype can be determined. The analysis of the immune response by subtyping of liver infiltrating lymphocytes indicates an adaptive mechanism suggesting in analogy with HAV, HBV and HCV that the virus itself is not cytopathic but liver damage is due to immune reaction.

    Objective: To determine the prevalence of hepatitis C virus (HCV) and hepatitis B virus (HBV) infection by detection of anti-HCV and hepatitis B surface antigen (HbsAg) in general population of Pakistan. Materials and Methods: Sera of healthy adult individuals who presented for medical evaluation as a pre-employment criteria in the Gulf region were examined for presence of hepatitis B surface antigen and anti-HCV antibody. Alanine aminotransferase levels were also determined. Results: A total of 47,538 individuals were examined. Out of these, 2528 (5.31%) were positive for anti-HCV and 1221 (2.56%) individuals had positive HBsAg. Hepatitis B surface antigen and anti-HCV both were found in 92 (0.19%) individuals. Mean age of subjects, positive for HCV antibody was 44 years and 40.5 years for HBV. Ninety-four percent individuals were males and 6% were females. Alanine aminotransferase (ALT) was normal in 56% of subjects with positive HCV and 84% of individuals with HBV. Conclusion: This study which evaluated predominantly a healthy male population, showed a high seroprevalence of anti-HCV and average seroprevalence of hepatitis B virus infection. A large majority of these patients was young and had normal ALT. (author)

    Objective: To investigate the hemodynamics of increasing portal venous pressure(PVP) in hepatocellular carcinoma patients complicated with hepatic arterioportal vein fistulas (HAPVF) and the diagnosis and therapy of intractable upper gastrointestinal hemorrhage caused by HAPVF. Methods: One hundred and fifteen cases of hepatocellular carcinoma with upper gastrointestinal hemorrhage were checked by hepatic arteriography and were treated through orifices embolization in cases with severe HAPCF by coils and/or ethanol. Results: Twenty-six out of 31 patients suffering intractable upper gastrointestinal hemorrhage have severe HAPVF (the main stem of portal veins are visible). However, there are only 15 patients with light HAPVF among the 84 patients who have mild upper gastrointestinal hemorrhage (the main stem of portal veins are invisible). After the embolization, all of the 26 patients who have severe HAPVF stopped bleeding. Among them, the main stem of hepatic arteries are occluded in 2 patients. Conclusion: The existence of severe HAPVF should be taken into consideration when intractable upper gastrointestinal hemorrhage occurs in hepatocellular carcinoma patients, and it can be diagnosed through hepatic artery DSA. Orifice embolization is the most effective method for such kind of hemorrhage. (authors)

    Orlistat was approved by the Food and Drug Administration in 1998 and has been shown to be superior to placebo in achieving weight loss. It is generally well tolerated. However, severe liver injury has been reported. We present a case of hepatic failure in a patient taking orlistat. A 54-year-old African-American woman with hypertension presented with hepatic failure. She had noticed increasing fatigue, jaundice and confusion. She used alcohol sparingly and denied tobacco or illicit drug use, but had been taking over-the-counter orlistat for the past two months. Physical examination revealed scleral icterus, jaundice, asterixis and slow speech. Laboratory testing showed markedly abnormal liver function tests with coagulopathy. Acute viral and autoimmune serologies were negative, as was toxicology screen. Liver biopsy showed necrotic hepatic parenchyma likely secondary to drug toxicity. Based upon her clinical presentation and time course, the pattern of liver injury seen on liver biopsy and lack of an alternative plausible explanation, her liver failure was most likely associated with orlistat use. She continued to deteriorate and ultimately underwent orthotopic liver transplantation. Fourteen cases of severe liver injury associated with orlistat use have been reported, four of which are detailed in the literature. This is the second published case of liver failure associated with over-the-counter orlistat usage. Clinicians should be aware of the growing number of cases associating liver injury and orlistat use and carefully monitor their patients on this medication for signs of hepatic dysfunction. © 2014 The Authors.

    Hepatic steatosis occurs in 40-70% of patients chronically infected with hepatitis C virus [chronic hepatitis C (CH-C)]. Hepatic steatosis in CH-C is associated with progressive liver disease and a low response rate to antiviral therapy. Gene expression profiles were examined in CH-C patients with and without hepatic steatosis, non-alcoholic steatohepatitis (NASH) and fibrosis. This study included 65 CH-C patients who were not receiving antiviral treatment. Total RNA was extracted from peripheral blood mononuclear cells, quantified and used for one-step reverse transcriptase-polymerase chain reaction to profile 153 mRNAs that were normalized with six 'housekeeping' genes and a reference RNA. Multiple regression and stepwise selection assessed differences in gene expression and the models' performances were evaluated. Models predicting the grade of hepatic steatosis in patients with CH-C genotype 3 involved two genes: SOCS1 and IFITM1, which progressively changed their expression level with the increasing grade of steatosis. On the other hand, models predicting hepatic steatosis in non-genotype 3 patients highlighted MIP-1 cytokine encoding genes: CCL3 and CCL4 as well as IFNAR and PRKRIR. Expression levels of PRKRIR and SMAD3 differentiated patients with and without superimposed NASH only in the non-genotype 3 cohort (area under the receiver operating characteristic curve=0.822, P-value 0.006]. Gene expression signatures related to hepatic fibrosis were not genotype specific. Gene expression might predict moderate to severe hepatic steatosis, NASH and fibrosis in patients with CH-C, providing potential insights into the pathogenesis of hepatic steatosis and fibrosis in these patients.

    Auto-immune hepatitis first presenting in the early postpartum period is rare. Immunosuppressive effects of pregnancy result in delayed manifestation of auto-immune hepatitis, and in established cases, the spontaneous improvements are there. Auto-immune hepatitis should be considered in the differential diagnosis of liver dysfunction first presenting in the early postpartum period. A case of postpartum hepatitis of auto-immune aetiology is being presented here. It is disease of unknown aetiology, characterised by inflammation of liver (as evidenced by raised serum transaminases, presence of interface hepatitis on histological examination), hypergammaglobulinaemia (> 1.5 times normal), presence of auto-antibodies [(antinuclear antibodies (ANA)], smooth muscle antibody (SMA) and antibody to liver-kidney microsome type 1 (LKM1) in the absence of viral markers ie, hepatitis B (HBsAg) and C (AntiHCV) and excellent response to corticosteroid therapy.

    To evaluate the serum levels of endozepine-4, their relation with ammonia serum levels, the grading of coma and the severity of cirrhosis, in patients with hepatic coma. In this study we included 20 subjects with Hepatic coma, 20 subjects with minimal hepatic encephalopathy (MHE) and 20 subjects control. All subjects underwent blood analysis, Child Pugh and Model for End - stage liver disease (MELD) assessment, endozepine-4 analysis. Subjects with hepatic coma showed significant difference in endozepine-4 (P blood ammonia concentration was noted to be raised in patients with hepatic coma, with the highest ammonia levels being found in those who were comatose. We also found a high correlation between endozepine-4 and ammonia (P < 0.001). In patients with grade IV hepatic coma, endozepine levels were significantly higher compared to other groups. This study suggests that an increased level of endozepine in subjects with higher levels of MELD was observed. In conclusion, data concerning involvement of the GABA-ergic system in HE coma could be explained by stage-specific alterations.

    Hepatic encephalopathy is a neuropsychiatric disorder of complex pathogenesis caused by acute or chronic liver failure. We investigated the effects of cannabidiol, a non-psychoactive constituent of Cannabis sativa with anti-inflammatory properties that activates the 5-hydroxytryptamine receptor 5-HT(1A) , on brain and liver functions in a model of hepatic encephalopathy associated with fulminant hepatic failure induced in mice by thioacetamide. Female Sabra mice were injected with either saline or thioacetamide and were treated with either vehicle or cannabidiol. Neurological and motor functions were evaluated 2 and 3 days, respectively, after induction of hepatic failure, after which brains and livers were removed for histopathological analysis and blood was drawn for analysis of plasma liver enzymes. In a separate group of animals, cognitive function was tested after 8 days and brain 5-HT levels were measured 12 days after induction of hepatic failure. Neurological and cognitive functions were severely impaired in thioacetamide-treated mice and were restored by cannabidiol. Similarly, decreased motor activity in thioacetamide-treated mice was partially restored by cannabidiol. Increased plasma levels of ammonia, bilirubin and liver enzymes, as well as enhanced 5-HT levels in thioacetamide-treated mice were normalized following cannabidiol administration. Likewise, astrogliosis in the brains of thioacetamide-treated mice was moderated after cannabidiol treatment. Cannabidiol restores liver function, normalizes 5-HT levels and improves brain pathology in accordance with normalization of brain function. Therefore, the effects of cannabidiol may result from a combination of its actions in the liver and brain. © 2011 The Authors.

    Objective: To observe the effect of iodized oil on radiofrequency thermal ablation (RFA) of hepatic neoplasms by using a cluster array of ten separate electrodes. Methods: The patients were divided into 2 groups, group A with transcatheter hepatic artery embolization, group B without transcatheter hepatic artery embolization. All patients were undergone radiofrequency ablation of hepatic neoplasms. Results: The time of RFA for group A was (9 ± 2.1) minutes, showing the diameter of necrosis of (5.3 ± 1.4) cm. The time of RFA for group B was (16 ± 4. 6) minutes demonstrating the diameter of necrosis of (3.5 ± 1.8) cm (P<0.01). Conclusions: These findings suggest that radiofrequency thermal ablation of hepatic neoplasms with transcatheter hepatic artery embolization using iodized oil might improve the safety and synergic effect

    Hepatitis B is the major health problem globally casting an enormous burden on health care system and major source of patient's misery. It is also an important cause of hepatocellular carcinoma and is likely to remain a serious health problem resulting in substantial morbidity and mortality for several decades to come. Objective of the study was to determine the level of awareness regarding hepatitis B among women attending obstetric and gynaecology clinic at Isra university Hospital. It was descriptive study and conducted in Obstetric and Gynaecology, Outpatient Department of Isra University Hospital, Hyderabad, Sindh from 2nd January to 3rd June 2008. Total 121 women of 20-50 years were gathered by sample of convenience. Information was collected on pre designed questionnaire containing questions regarding basic knowledge of disease, its causative organism, route of transmission and its prevention. Informed consent was taken. All the data was analyzed by computer software Programme of Social Sciences (SPSS version 11.0). Out of 121 women, 82 (67.76%) women correctly responded that virus is a cause of hepatitis. When they were asked about the organs affected by hepatitis B infection, 91 (75.20%) correctly mentioned liver, while 30 (24.79%) gave incorrect answer. Regarding mode of transmission of HBV 41 (33.88%) mentioned infected blood transfusion, 49 (40.49%) contaminated needles, 46(38.0%) un-sterilised instruments, 21 (17.35%) from mother to child and only 23 (19.0%) mentioned sexual intercourse. Only 51 (42.14%) women knew that vaccine is available for prevention. This study found that the knowledge about hepatitis B virus among women is inadequate and there are certain misconceptions regarding its mode of transmission through sharing room, touching etc which needs to be clarified. Majority of women don't know that HBV infection can be prevented by using condoms. (author)

    The aim of this study was to determine the role of the CT scan in blunt hepatic injury and the significance of CT degree of hepatic injury in the decision making of treatment plan. We retrospectively analyzed the CT findings of 22 patients with hepatic injury. We graded hepatic injury on CT scan into five according to the severity. Clinical records, type of management and clinical outcome of the patients were also reviewed. Of the 22 patients, 17 had conservative treatment and five had surgery. The numbers of patients treated conservatively were 0, 4, 11, 2 and 0 in the grade 1, 2, 3, 4, and 5, retrospectively and the numbers of surgically treated cases were 0, 0, 3, 2 and 0 respectively. There was no significant statistical difference between surgically and conservatively treated groups(p-value > 0.05). All patients with conservatively treated group were hemodynamically stable and had no complication during hospitalization. Hemoperitoneum was observed in 11 of 22 patients. In blunt hepatic injury, CT plays an important role in the demonstration of location and extent of the hepatic injury, size of hemoperitoneum and the post operative course. However, we believe that physiologic status of the patients may be more important than the extent of CT based hepatic injury for determining a mode of treatment

    A fluid adjuvanted vaccine consisting of inactivated hepatitis virus (iH) and leptospirae antigens (L) was developed. The vaccine (Kavak iHL; Duphar) was tested in several vaccination programmes both alone and in combination with freeze dried measles (M) or distemper (D) vaccines. The results demonstrate that this new vaccine is also effective in pups with maternally derived antibodies, although a second vaccination at 14 weeks of age is recommended to boost the first vaccination. For the booster vaccination either the iHL-vaccine or the liver attenuated hepatitis vaccine (H) can be used.

    Objective: To assess the efficacy of 131 I treatment for Graves' disease (GD) complicated with hepatic function injury in order to provide guidance for clinical practice. Methods: A total of 840 GD cases complicated with hepatic function injury were retrospectively reviewed after 131 I treatment. Analysis of variance and Dunnett t test were used to compare serum FT 3 , FT 4 , and TSH levels before and 1, 3, and 6 months after 131 I therapy. R × C table χ 2 test was used to compare therapeutic efficacies among cases with different degrees and types of hepatic function injuries. Analysis of variance and Dunnett t test were used to evaluate recovery time of different degrees of hepatic function injuries. Cross classification 2 × 2 table correlation analysis was adopted to assess the correlation between 131 I therapeutic efficacies of GD and recovery efficacies of hepatic function. Results: The curative rate for GD was 76.8% (645/840). There were significant changes of FT 3 ((25.74 ± 5.81), (15.54 ± 4.12), (12.76 ± 2.35) and (7.95 ± 1.64) pmol/L, respectively; F=5007.958, t=54.455, 69.297 and 94.976, all P<0.05), FT 4 ((75.84 ± 16.78), (45.69 ±8.96), (36.81 ± 5.03) and (25.17 ±.4.46) pmol/L, respectively; F=3876.410, t=513.602, 664.871 and 863.157, all P<0.05) and TSH ((0.01 ±0.02), (0.02±0.08), (0.85 ±0.36) and (1.26 ± 0.54) mU/L, respectively; F=3050.430, t=2.627, 46.989 and 78.315, all P<0.05) before and 1,3,and 6 months after 131 I treatment. The curative rate of hepatic function abnormality was 79.2% (665/840). For mild, medium and severe hepatic function injury patients, curative rates were 88.4% (420/475), 68.8% (214/311) and 57.4% (31/54), respectively. The curative rate of patients with mild hepatic function injury was significantly higher than those with medium and severe hepatic function injury (χ 2 =46.338, 37.100, respectively, both P<0.01), and the recovery time was significantly shorter in patients with mild hepatic function injury

    additionally been taking symbiotic besides who the basic treatment; group B - patients to whom basic therapy has been applied. Thus, 2 groups of 54 patients have been formed. The control group, which did not differ from the groups of patients by age and gender, has been made up of 17 clinically healthy persons. For patients of group A patients we have been using symbiotic — Bifilact Extra, TM "Ariadna", Ukraine, certificate of registration No. 05.08.07 / 4089 of 02.10.2000 containing Lactobacillus acidophilus and Bifidobacterium bifidum. Determination of the qualitative and quantitative composition of microbiocenosis of the large intestine has been carried out in accordance with current normative documents as per generally accepted methods. The degree of dysbiotic disturbances was determined by V.M. Bondarenko in 2007. Microbiological studies of the material have been conducted in dynamics before the treatment and 7 days after the end of the course of treatment with the symbiotic. Statistical processing of the data was carried out using the Statistics-10 software package, Microsoft Office Excel 2003. Results. In all patients, there was an acute cyclic course of HBV infection with clinically expressed jaundice in the background of cytolysis syndrome. By results of researches of the species composition of the microflora of the colon in jaundice period of AHB, a violation of the microecology of this biotope of different degrees was found in 96.3% of patients. It turned out that the degree of dysbiotic shifts did not depend on the severity of hepatitis. About half of patients had dysbiosis of grade III. Analyzing the species composition and population level of the microflora of the colon in patients with acute hepatitis B in the jaundice period, there was elimination or severe deficiency of bifidobacteria and lactobacilli and the vegetation of opportunistic bacteria. But the most common cause of local microecology was Candida spp, it was determined in 30,8 % of the total number

    Objective This study was performed to understand transcriptional changes in the genes involved in gluconeogenesis and glycolysis pathways following castration of bulls. Methods Twenty Korean bulls were weaned at average 3 months of age, and castrated at 6 months. Liver tissues were collected from bulls (n = 10) and steers (n = 10) of Korean cattle, and hepatic gene expression levels were measured using quantitative real-time polymerase chain reaction. We examined hepatic transcription levels of genes encoding enzymes for irreversible reactions in both gluconeogenesis and glycolysis as well as genes encoding enzymes for the utilization of several glucogenic substrates. Correlations between hepatic gene expression and carcass characteristics were performed to understand their associations. Results Castration increased the mRNA (3.6 fold; pgluconeogenesis reactions from pyruvate to glucose and enzymes responsible for incorporation of glucogenic substrates including lactate, glycerol, and propionate. Hepatic gluconeogenic gene expression levels were associated with intramuscular fat deposition. PMID:29502393

    In order to find out the correlations between serum leptin levels and viral hepatitis, the serum leptin levels in 167 patients with viral chronic hepatitis, 87 patients with fatty liver, and 80 control subjects were determined by radioimmunoassay. The liver function (ALT, AST), glucose(Glu) and total cholesterol(TC) in these patients were also measured. Compared with controls and patients with fatty liver, the levels of serum leptin in patients with viral hepatitis were significantly increased (P 0.05). The increase of serum leptin levels in the patients with viral hepatitis was correlated positively with the severity of liver inflammation. Therefore, the leptin can be regarded as an indicator to reflect the severity of liver inflammation. (authors)

  13. Capsaicin affects brain function in a model of hepatic encephalopathy associated with fulminant hepatic failure in mice

    2009-01-01

    Background and purpose: Hepatic encephalopathy is a neuropsychiatric syndrome caused by liver failure. In view of the effects of cannabinoids in a thioacetamide-induced model of hepatic encephalopathy and liver disease and the beneficial effect of capsaicin (a TRPV1 agonist) in liver disease, we assumed that capsaicin may also affect hepatic encephalopathy. Experimental approach: Fulminant hepatic failure was induced in mice by thioacetamide and 24 h later, the animals were injected with one of the following compound(s): 2-arachidonoylglycerol (CB1, CB2 and TRPV1 receptor agonist); HU308 (CB2 receptor agonist), SR141716A (CB1 receptor antagonist); SR141716A+2-arachidonoylglycerol; SR144528 (CB2 receptor antagonist); capsaicin; and capsazepine (TRPV1 receptor agonist and antagonist respectively). Their neurological effects were evaluated on the basis of activity in the open field, cognitive function in an eight-arm maze and a neurological severity score. The mice were killed 3 or 14 days after thioacetamide administration. 2-arachidonoylglycerol and 5-hydroxytryptamine (5-HT) levels were determined by gas chromatography-mass spectrometry and high-performance liquid chromatography with electrochemical detection, respectively. Results: Capsaicin had a neuroprotective effect in this animal model as shown by the neurological score, activity and cognitive function. The effect of capsaicin was blocked by capsazepine. Thioacetamide induced astrogliosis in the hippocampus and the cerebellum and raised brain 5-hydroxytryptamine levels, which were decreased by capsaicin, SR141716A and HU-308. Thioacetamide lowered brain 2-arachidonoylglycerol levels, an effect reversed by capsaicin. Conclusions: Capsaicin improved both liver and brain dysfunction caused by thioacetamide, suggesting that both the endocannabinoid and the vanilloid systems play important roles in hepatic encephalopathy. Modulation of these systems may have therapeutic value. PMID:19764982

    1988-01-01

    Intraperitoneal administration of cadmium chloride to 8-12 weeks old CBA-mice enhanced hepatic lipid peroxidation. A positive correlation between cadmium chloride dose and level of peroxidation was observed in both male and female mice. A sex-related difference in mortality was not observed...... but at a dose of 25 mumol CdCl2/kg the level of hepatic lipid peroxidation was higher in male mice than in female mice. The hepatic lipid peroxidation was not increased above the control level in 3 weeks old mice, while 6 weeks old mice responded with increased peroxidation as did 8-12 weeks old mice....... The mortality after an acute toxic dose of cadmium chloride was the same in the three age groups. Pretreatment of mice with several low intraperitoneal doses of cadmium chloride alleviated cadmium induced mortality and lipid peroxidation. The results demonstrate both age dependency and a protective effect...

    2017-05-04

    Hepatitis B vaccine is regarded as the most effective method for the prevention of hepatitis B virus (HBV) infection. However, several factors such as age, body mass index and immunocompetent state have been reported to be associated with reduced immunization responses. The present commentary was aimed to discuss the influences of obesity on the immunogenicity of hepatitis B vaccines. Available peer-reviewed literatures, practice guidelines, and statistics published on hepatitis B vaccine in obesity between 1973 and 2015. Obesity was significantly associated with non-response to hepatitis B vaccine immunization. The risk of nonresponsiveness of hepatitis B vaccine among obese people increased with BMI. Moreover, the obesity might lead to an increased risk of HBV vaccine-escape mutations. The mechanism responsible for decreased immunization responses in obesity included leptin-induced systemic and B cell intrinsic inflammation, impaired T cell responses and lymphocyte division and proliferation. Therefore, more studies should be performed to analyze the influences of obesity on the immunogenicity of hepatitis B vaccines to improve the immunoprotecive effect of hepatitis B vaccines in future.

    Hepatic trauma is a rare surgical emergency with significant morbidity and mortality. Therapeutic strategies have been controversially discussed during the last decades. The medical records of 47 consecutive patients with hepatic trauma treated at the University Hospital of Leipzig between 2004 and 2008 were retrospectively reviewed for the severity of liver injury, management, morbidity, and mortality and compared to a preceding cohort. Logistic regression analysis was performed to identify risk factors influencing mortality. Compared to 63 patients treated between 1993 and 2003, moderate liver injuries (grades I-III) occurred more frequently (p = 0.0006), and the proportion of patients that were managed operatively decreased from 68.9% to 37.5%. Twenty patients (42.6%) were treated conservatively (all grades I to III) and 27 surgically (47.4%). In detail, five patients were treated by hepatic packing alone, 13 by suture or coagulation, five by atypical resection, and four by hemihepatectomy. The overall mortality was 8.5% with a liver-related mortality rate of 2.1%. According to severity grades I-III, IV, and V, mortality rates were 0%, 18.2%, and 50.0%, respectively. Univariate analysis identified Injury Severity Score (ISS) >30, Moore grades IV and V, hemoglobin at admission 12 erythrocyte concentrates to be significant risk factors for early posttraumatic death, while multivariate analysis only ISS >30 revealed to be of prognostic significance for early postoperative survival. Compared to a previous cohort in the same hospital, more patients were treated conservatively. Management of liver injuries presented with a low liver-related mortality rate. Grades I-III injuries can safely be treated by conservative means with excellent results. However, complex hepatic injuries may often require surgical treatment ranging from packing to complex hemihepatectomy. Hence, for selection of appropriate therapeutic options, patients with hepatic injuries should be treated

    Hepatitis A virus is an infection of liver; it is hyperendemic in vast areas of the world including India. In most cases it causes an acute self limited illness but rarely fulminant. There is growing concern about change in pattern from asymptomatic childhood infection to an increased incidence of symptomatic disease in the adult population. In-depth analysis of immunological, viral quantification and genotype of acute and fulminant hepatitis A virus. Serum samples obtained from 1009 cases of suspected acute viral hepatitis was employed for different biochemical and serological examination. RNA was extracted from blood serum, reverse transcribed into cDNA and amplified using nested PCR for viral quantification, sequencing and genotyping. Immunological cell count from freshly collected whole blood was carried out by fluorescence activated cell sorter. Fulminant hepatitis A was mostly detected with other hepatic viruses. CD8+ T cells count increases in fulminant hepatitis to a significantly high level (P = 0.005) compared to normal healthy control. The immunological helper/suppressor (CD4+/CD8+) ratio of fulminant hepatitis was significantly lower compared to acute cases. The serologically positive patients were confirmed by RT-PCR and total of 72 (69.2%) were quantified and sequenced. The average quantitative viral load of fulminant cases was significantly higher (P viral load defines the severity of the fulminant hepatitis A. Phylogenetic analysis of acute and fulminant hepatitis A confirmed genotypes IIIA as predominant against IA with no preference of disease severity.

    To describe the CT and MRI features of hepatic sinusoidal obstruction syndrome (HSOS) caused by herbal medicine Gynura segetum. The CT and MRI features of 16 consecutive Gynura segetum induced HSOS cases (12 men, 4 women) were analyzed. Eight patients had CT; three patients had MRI, and the remaining five patients had both CT and MRI examinations. Based on their clinical presentations and outcomes, the patients were classified into three categories: mild, moderate, and severe. The severity of the disease was also evaluated radiologically based on the abnormal hepatic patchy enhancement in post-contrast CT or MRI images. Ascites, patchy liver enhancement, and main right hepatic vein narrowing or occlusion were present in all 16 cases. Hepatomegaly and gallbladder wall thickening were present in 14 cases (87.5%, 14/16). Periportal high intensity on T2-weighted images was present in 6 cases (75%, 6/8). Normal liver parenchymal enhancement surrounding the main hepatic vein forming a clover-like sign was observed in 4 cases (25%, 4/16). The extent of patchy liver enhancement was statistically associated with clinical severity classification (kappa = 0.565). Ascites, patchy liver enhancement, and the main hepatic veins narrowing were the most frequent signs of herbal medicine induced HSOS. The grade of abnormal patchy liver enhancement was associated with the clinical severity.

    The current treatment recommendation for chronic hepatitis C virus infection is the combination of peginterferon and ribavirin for 24 or 48 weeks, depending on the viral genotype. The aim of the therapy is to obtain a sustained virological response. To report our experience in the treatment of chronic hepatitis C. Analysis of 52 patients treated between September 2000 and June 2009. Patients with genotype 1 or 5 were treated with peginterferon alpha 2a (180 ug/week) and ribavirin (1000 mg/day for those weighing less than 75 kg and 1200 mg/day for those weighing more than 75 kg) during 48 weeks. Patients with genotypes 2 and 3 were treated for 24 weeks with the same dose of peginterferon and ribavirin 800 mg/day. Viral genotypes 1, 2, 3 and 5 were present in 81, 4, 11 and 4% of patients, respectively. Twenty four patients (46 %), 18 with genotype 1, achieved a sustained viral response. Age was the only variable that influenced the response to treatment. Approximately half of the patients with chronic hepatitis C, achieve a sustained viral response with peginterferon and ribavirin.

    Full Text Available Abstract Background The epidemiology of viral hepatitis during pregnancy is essential for health planners and programme managers. While much data exist concerning viral hepatitis during pregnancy in many African countries, no proper published data are available in Sudan. Aim The study aimed to investigate the sero-prevalance and the possible risk factors for hepatitis B virus (HBV and hepatitis C virus (HCV among antenatal care attendants in central Sudan. Methods During 3 months from March–June 2006, sera were collected from pregnant women at Umdurman Maternity Hospital in Sudan, and they were tested for markers of hepatitis B virus (HBVsAg and HCV. Results HBVsAg was detected in 41 (5.6% out 728 women, Anti-HCV was detected in 3 (0.6% out of 423 women, all of them were not aware of their condition. Age, parity, gestational age, residence, history of blood transfusion, dental manipulations, tattooing and circumcision did not contribute significantly to increased HBVsAg sero-positivity. Conclusion Thus 5.6% of pregnant women were positive for HBVsAg irrespective of their age, parity and socio-demographic characteristics. There was low prevalence of Anti-HCV.

    Concanavalin-A (Con-A) hepatitis is regarded as a T cell-mediated model of acute liver injury. Mincle is a C-type lectin receptor (CLR) that is critical in the immune response to mycobacteria and fungi, but does not have a well-defined role in pre-clinical models of non-pathogen mediated inflammation. Since Mincle can ligate the cell death ligand SAP130, we postulated that Mincle signaling drives intrahepatic inflammation and liver injury in Con-A hepatitis. Acute liver injury was assessed in the murine Con-A hepatitis model using C57BL/6, Mincle−/−, and Dectin-1−/− mice. The role of C/EBPβ and HIF-1α signaling was assessed using selective inhibitors. We found that Mincle was highly expressed in hepatic innate inflammatory cells and endothelial cells in both mice and humans. Furthermore, sterile Mincle ligands and Mincle signaling intermediates were increased in the murine liver in Con-A hepatitis. Most significantly, Mincle deletion or blockade protected against Con-A hepatitis whereas Mincle ligation exacerbated disease. Bone marrow chimeric and adoptive transfer experiments suggested that Mincle signaling in infiltrating myeloid cells dictates disease phenotype. Conversely, signaling via other CLRs did not alter disease course. Mechanistically, we found that Mincle blockade decreased the NF-κβ related signaling intermediates, C/EBPβ and HIF-1α, both of which are necessary in macrophage-mediated inflammatory responses. Accordingly, Mincle deletion lowered production of nitrites in Con-A hepatitis and inhibition of both C/EBPβ and HIF1-α reduced the severity of liver disease. Our work implicates a novel innate immune driver of Con-A hepatitis and, more broadly, suggests a potential role for Mincle in diseases governed by sterile inflammation. PMID:27559045

    99m Tc-diethylenetriamine-pentaacetic acid-galactosyl human serum albumin( 99m Tc-GSA) scintigraphy has been reported as a useful study of hepatic functional reserve recently. We have performed 99m Tc-N-pyridoxyl-5-methyl-tryptophan( 99m Tc-PMT) and 99m Tc-GSA preoperatively for evaluation of hepatic functional reserve and compared the usefulness of those scintigraphy study. Twenty-four patients who were the candidates of hepatic resection underwent 99m Tc-PMT scintigraphy preoperatively. Hepatic blood flow coefficient (K value), the amount of hepatic blood flow (HBF), and the ratio of portal blood flow (PVR) were computed. 99m Tc-GSA scintigraphy was also performed within two weeks of the 99m Tc-PMT scintigraphy, and the ratio of disappearance (HH 15 ) and the hepatic uptake ratio (LHL 15 ) were computed. The relationship between K value, HBF, PVR, HH 15 and LHL 15 was analyzed. Their correlation with other liver function tests was also examined. K value and HBF did not show statistically significant correlations with HH 15 and LHL 15 , PVR correlated statistically significantly HH 15 and LHL 15 . K value correlated with the preoperative values of cholinesterase, Fischer ratio, γ-globulin, ICGR 15 , albumin, and platelet count. There was a statistically significant correlation between LHL 15 and the value of cholinesterase, γ-globulin, platelet count, and Fischer ratio. When the liver resection of subsegmentectomy or more was indicated in 10 patients, nine patients had LHL 15 value less than 0.9 which delineated possibility of poor prognosis. However, judging from K value and HBF, liver resection was considered feasible and it was all successfully performed, resulting in good prognosis. From this study, it is suspected that 99m Tc-GSA scintigraphy reflect the severity of liver fibrosis and the amount of portal blood flows, and 99m Tc-PMT scintigraphy reflect the hepatic blood flow and ability of protein synthesis. It was proved that 99m Tc-PMT scintigraphy is

    Although hepatic steatosis (HS) has an association with hepatitis C virus (HCV) infection, an association with hepatitis B virus (HBV) is controversial. We performed a meta-analysis to evaluate HS prevalence and risk factors, in HBV infection. Standard guidelines for performance of meta-analyses were followed. Studies with HS assessed by histology were included. Pooled odd ratios (OR) and standardized mean differences (SMD) were obtained with the random-effects model and DerSimonian-Laid method. Seventeen out of 21 studies were included, comprising 4100 HBV infected patients. Overall HS prevalence was 29.6%. Eight studies also included 945 HCV infected patients, showing decreased risk of HS in HBV versus HCV patients (OR 0.55, 95%CI [0.45-0.67], P SMD 2.17, 95%CI [1.23, 3.11], P SMD 0.84, 95%CI [0.00, 1.67], P = 0.049), triglycerides (SMD 1.18, 95%CI [0.48, 1.89], P = 0.001), cholesterol (SMD 0.88, 95%CI [0.31, 1.45], P = 0.003), moderate alcohol consumption (OR 1.54, 95%CI [1.10-2.15], P = 0.011) and negatively with HBV DNA (SMD -74.12, 95%CI [-82.93, -65.31], P infected patients, relating to metabolic factors but not with hepatic histology severity. A puzzling strong negative association between viral load and HS, may even suggest a protective effect of the virus on HS. © 2011 Journal of Gastroenterology and Hepatology Foundation and Blackwell Publishing Asia Pty Ltd.

    Hepatic encephalopathy has been listed as a differential for llamas displaying neurologic signs, but it has not been histopathologically described. This report details the neurologic histopathologic findings associated with 3 cases of hepatic lipidosis with concurrent neurologic signs and compares them to 3 cases of hepatic lipidosis in the absence of neurologic signs and 3 cases without hepatic lipidosis. Brain from all 3 llamas displaying neurologic signs contained Alzheimer type II cells, which were not detected in either subset of llamas without neurologic signs. Astrocytic immunohistochemical staining intensity for glial fibrillary acid protein was decreased in llamas with neurologic signs as compared to 2 of 3 llamas with hepatic lipidosis and without neurologic signs and to 2 of 3 llamas without hepatic lipidosis. Immunohistochemical staining for S100 did not vary between groups. These findings suggest that hepatic encephalopathy may be associated with hepatic lipidosis in llamas.

    To evaluate the usefulness of screening liver ultrasonography (US) for hepatocellular carcinoma (HCC) detection in patients with chronic hepatitis or hepatic cirrhosis caused by hepatitis B virus (HBV). A retrospective study was performed with 1,189 patients with clinical hepatopathy caused by HBV who underwent screening liver US for HCC detection at least twice. All patients were followed up with liver US examinations (mean, 8.3 times), CT, or MR for at least 3 months (range, 3-102 months; mean, 47 months) for the detection of HCC. The study population was divided into two groups: chronic hepatitis (n=492) and hepatic cirrhosis (n=697), which was further divided into two groups with (n=156) or without (n=541) evident shrinkage. The radiologic examinations that had detected HCC for the first time were analyzed and compared between the groups. Among 20 (4.1%) patients with chronic hepatitis and 132 (18.9%) patients with hepatic cirrhosis diagnosed as HCC, screening US was the modality of detection in 17 (85.0%) of 20 patients with chronic hepatitis and 76 (57.6%) of 132 patients with hepatic cirrhosis (p=0.038, Chi-square test). The detection rate of HCC on screening US between the chronic hepatitis and hepatic cirrhosis with evident shrinkage (51.4%, 19/37) showed a significant difference (p=0.027, Chi-square test). For chronic liver disease caused by HBV, screening US for HCC detection is more useful in patients with chronic hepatitis than with hepatic cirrhosis with evident shrinkage

    Hepatitis E is a systemic disease affecting the liver predominantly and caused by infection with the hepatitis E virus (HEV). HEV has marked genetic heterogeneity and is known to infect several animal species including pigs, boar, deer, mongoose, rabbit, camel, chicken, rats, ferret, bats and cutthroat trout. HEV is the sole member of the family Hepeviridae and has been divided into 2 genera: Orthohepevirus (mammalian and avian HEV) and Piscihepevirus (trout HEV). Human HEVs included within the genus Orthohepevirus are designated Orthohepevirus A (isolates from human, pig, wild boar, deer, mongoose, rabbit and camel). Hepatitis E is an important public health concern, and an estimated one-third of the world population has been infected with HEV. In recent years, autochthonous hepatitis E is recognized as a clinical problem in industrialized countries. Several animal species especially domestic swine, wild boar and wild deer are reservoirs of genotype HEV-3 and HEV-4 in these countries. Human infections occur through intake of uncooked or undercooked meat of the infected animals and pig livers or sausages made from these livers and sold in supermarkets. HEV can be transmitted through blood and blood component transfusions, and donor screening for HEV is under serious consideration. Chronic hepatitis E resulting in rapidly progressive liver cirrhosis and end-stage liver disease has been described in organ transplant patients. Ribavirin monotherapy attains sustained virological response in most patients. HEV 239 vaccine has been marketed in China and its long-term efficacy over four and a half years reported. © 2015 John Wiley & Sons Ltd.

    Background: The detection rate of hepatic falciform ligament artery (FLA) has been reported as ranging from 2-25%. The rate of FLA on laparotomy, however, is reported to be higher, at 68%. Purpose: To compare the detection rate of FLA on computed tomography hepatic arteriography (CTHA) with that on angiography and dynamic CT, and to clarify the clinical significance of FLA in patients with chronic liver disease. Material and Methods: 126 consecutive patients underwent CTHA angiography and dynamic CT to evaluate suspected liver tumors. Liver function was classified as follows: normal, n=5; Child-Pugh class A, n=94; B, n=21; and C, n=6. All CT images were obtained using multidetector (MDCT) scanners (Aquilion; Toshiba, Tokyo (JP)). For CTHA, CT images were obtained during contrast material injection through the left hepatic, proper, or common hepatic artery. On CT, FLAs were retrospectively identified within the hepatic falciform ligament and the hepatic round ligament by the paging method on a workstation (TWS-5000; Toshiba, Tokyo (JP)). The detection rates were compared among the three modalities (hepatic arterial phase of dynamic CT, CTHA, and angiography). The calibers of FLA were also correlated with the hepatic function of the patients. Results: The detection rates of FLA by angiography, dynamic CT, and CTHA were 37% (47/126), 10% (13/126), and 77% (97/126), respectively. The calibers of FLA increased as the hepatic function deteriorated (P=0.001). Conclusion: The detection rates of FLA with CTHA are far higher than those with angiography and dynamic CT. Careful interpretation with recognition of FLA on CTHA images is important, as inadvertent embolization or chemotherapeutic infusion of the FLA may result in supraumbilical skin rash

    Hepatic dysfunction in a patient with thyrotoxicosis may result from hyperthyroidism per se, as a side effect of antithyroid drugs, and causes unrelated to hyperthyroidism which sometimes causes diagnostic and therapeutic difficulties. A young female patient was admitted to our hospital with symptoms of thyrotoxicosis, diffuse goiter and ophthalmopathy along with cholestatic pattern of jaundice, and proximal muscle weakness. She was treated with propylthiouracil with gradual recovery. She was continuing her antithyroid medication with regular follow-up. The patient was readmitted a few months later with worsening thyrotoxicosis, proximal muscle weakness, fever, and a hepatocellular pattern of jaundice with sepsis. Propylthiouracil was stopped and lithium along with steroid coverage was given to control her thyrotoxicosis which was later changed to methimazole. Broad spectrum antibiotic therapy was also started but without any response. During her hospital stay, the patient also developed a flaccid paraplegia resembling Guillain-Barre syndrome. IV steroid was started for the neuropathy but meanwhile the patient succumbed to her illness. So in centers where facility for radioiodine therapy is not readily available, some definite well-tested protocols should be formulated to address such common but complicated clinical situations.

    Evaluation of the technical success, patient safety and technical effectiveness of magnetic resonance (MR)-guided microwave ablation of hepatic malignancies. Institutional review board approval and informed patient consent were obtained. Fifteen patients (59.8 years ± 9.5) with 18 hepatic malignancies (7 hepatocellular carcinomas, 11 metastases) underwent MR-guided microwave ablation using a 1.5-T MR system. Mean tumour size was 15.4 mm ± 7.7 (7-37 mm). Technical success and ablation zone diameters were assessed by post-ablative MR imaging. Technique effectiveness was assessed after 1 month. Complications were classified according to the Common Terminology Criteria for Adverse Events (CTCAE). Mean follow-up was 5.8 months ± 2.6 (1-10 months). Technical success and technique effectiveness were achieved in all lesions. Lesions were treated using 2.5 ± 1.2 applicator positions. Mean energy and ablation duration per tumour were 37.6 kJ ± 21.7 (9-87 kJ) and 24.7 min ± 11.1 (7-49 min), respectively. Coagulation zone short- and long-axis diameters were 31.5 mm ± 10.5 (16-65 mm) and 52.7 mm ± 15.4 (27-94 mm), respectively. Two CTCAE-2-complications occurred (pneumothorax, pleural effusion). Seven patients developed new tumour manifestations in the untreated liver. Local tumour progression was not observed. Microwave ablation is feasible under near real-time MR guidance and provides effective treatment of hepatic malignancies in one session. (orig.)

    The effect of long-term voluntary fasting on hematologic variables, biochemical profiles, and liver histologic findings was assessed in 15 obese cats (> 40% overweight). Clinical signs and laboratory results consistent with hepatic lipidosis were observed in 12 of 15 cats after 5 to 7 weeks of fasting, and were associated with 30 to 35% reduction of initial body weight. Histologic examination of successive liver biopsy specimens revealed that obesity was not associated with liver parenchymal lipid accumulation, but that fasting resulted in lipidosis in all 15 cats. The long-term fast was associated with an early (after 2 to 4 weeks of fasting) and significant (P hepatic-associated enzyme activities and in total and direct serum bilirubin concentrations. Significant (P hepatic lipidosis, cats appeared to tolerate the fast without other adverse effect. This study confirmed that long-term fasting may induce clinical hepatic lipidosis in obese cats. Fasting appears to induce a syndrome of hepatic lipidosis that is indistinguishable from feline idiopathic hepatic lipidosis and may be an appropriate model to study the pathophysiologic features and treatment of hepatic lipidosis.

    Full Text Available Background Alcoholic liver disease is a major cause of end-stage liver disease worldwide and severe forms of alcoholic hepatitis are associated with a high short-term mortality. Objectives To analyze the importance of age-bilirubin-INR-creatinine (ABIC score as an index of mortality and predictor for complications in patients with alcoholic hepatitis. To evaluate its correlation with those complications, with risk of death, as well as the scores model for end stage liver disease (MELD and Maddrey’s discriminat function. Methods A total of 46 medical records of patients who had been hospitalized with alcoholic hepatitis were assessed retrospectively with lab tests on admission and after seven days. Score calculations were carried out and analyzed as well. Results The scores showed positive reciprocal correlation and were associated with both hepatic encephalopathy and ascites. ABIC index, which was classified as high risk, presented as a risk factor for these complications and for death. In univariate logistic regression analysis of mortality, the ABIC index at hospital admission odds ratio was 19.27, whereas after 7 days, it was 41.29. The average survival of patients with ABIC of low and intermediate risk was 61.1 days, and for those with high risk, 26.2 days. Conclusions ABIC index is a predictor factor for complications such as ascites and hepatic encephalopathy, as well as for risk of death. Thus, it is a useful tool for clinical practice.

    Assessment of hepatic fibrosis is important for determining prognosis, guiding management decisions, and monitoring disease. Histological evaluation of liver biopsy specimens is currently considered the reference test for staging hepatic fibrosis. Since liver biopsy carries a small but significant risk, noninvasive tests to assess hepatic fibrosis are desirable. This editorial gives an overview on noninvasive methods currently available to determine hepatic fibrosis and their diagnostic accur...

    Objective: To evaluate the angiographic feature of hepatic vein obstruction. Methods Forty-five patients (male 23, female 22, age 9-54 years) suffered from hepatic vein obstruction. The inferior vena cavography and the hepatic venography were performed in all cases. Results: IVC was free in 37 patients with hepatic vein obstruction, both IVC and HV were obstructed in 8 patients. The local or long stenosis of IVC was found in 31 inferior vena cavography. The diameter of IVC was normal in 12 patients. The sign of membranous dome was found in hepatic vein orifice in 5 cases and in accessory hepatic vein orifice in 4 cases. Intrahepatic venous collaterals were found in 45 cases. Conclusion: Hepatic vein obstruction can be reproached primarily in inferior vena cavography, the membranous dome is a direct sign of membranous obstruction of HV and AHV in inferior vena cavography. The selected hepatic venography can provide reliable evidence to diagnose hepatic vein obstruction

    2014-01-01

    Aim: To evaluate liver necro-inflammation and function by using gadoxetic acid-enhanced dynamic contrast-enhanced magnetic resonance imaging (DCE-MRI), with histological analysis as the reference standard. Materials and methods: Seventy-nine subjects (21 healthy subjects; 58 chronic hepatitis patients) who received gadoxetic acid-enhanced DCE-MRI were divided into three subgroups: no (A0, n = 31), mild (A1, n = 27), and moderate–severe (A2–A3, n = 21) activities. Two DCE-MRI models were measured: (1) a dual-input single-compartment model to obtain absolute arterial, portal venous, and total blood flow, arterial fraction (ART), distribution volume, and mean transit time; (2) a curve analysis method to obtain peak, slope, and AUC (area under curve). The serum alanine aminotransferase (ALT) and aspartate aminotransferase (AST) levels also obtained. Statistical testing included Kruskal–Wallis tests for continuous data, Pearson's correlation tests, and multiple linear regression analyses. Results: Hepatic necro-inflammatory activity grades were significantly correlated with fibrotic stages, serum ALT level, ART and AUC. ART was helpful to predict the mild activity (≤A1 versus >A1; Az = 0.728), whereas AUC could differentiate no activity from any activity (A0 versus >A0; Az = 0.703). Peak, slope and AUC were all associated with AST and ALT (p < 0.05). Conclusion: Gadoxetic acid-enhanced DCE-MRI parameters may be used to evaluate the severity of hepatic necro-inflammation and function

  5. Measurement of hepatic volume and effective blood flow with radioactive colloids: Evaluation of development in liver diseases

    Changes in hepatic volume and the blood flow effectively perfusing the liver parenchyma were studied as an assessment of the severity of liver diseases. Hepatic effective blood flow was estimated as the hepatic fractional clearance of radioactive colloids, obtained from the disappearance rate multiplied by the fraction of injected dose taken up by the liver. The hepatic fractional clearance was normal or not markedly decreased in patients with acute hepatitis which had developed favorably, but was severely decreased in patients with fulminant hepatitis. In liver diseases, the ratio of hepatic volume to fractional clearance was found to increase as the clearance decreased. In subjects with normal clearance, hepatic fractional clearance was correlated significantly with liver volume, indicating that hepatic effective blood flow is proportional to parenchymal volume in an unanesthetized, resting state. In biopsied cases changes in volume and blood flow accorded well with changes indicated by morphological criteria. In chronic persistent hepatitis, effective hepatic blood flow is not diminished. However, hepatic blood flow were observed between the cirrhosis or chronic aggressive hepatitis, and normal control groups. Extension of chronic inflammatory infiltration into the parenchyma distinguishes chronic aggressive hepatitis from chronic persistent hepatitis. Architecture is often disturbed in the former. These changes should be accompanied by disturbance of microcirculation. The present study indicates that the decrease in effective hepatic blood flow in chronic hepatitis and cirrhosis has two aspects: one is a summation of microcirculatory disturbances, and the other is a decrease in liver cell mass.

    Acute hepatitis A is a fecal-oral transmitted disease related to inadequate sanitary conditions. In addition to its traditional classification, several outbreaks in the men who have sex with men (MSM) population have resulted in acute hepatitis A being recognized as a sexually transmitted disease. However, few studies have clarified the clinical manifestations in these outbreaks involving the MSM population. Beginning in June 2015, there was an outbreak of acute hepatitis A involving the MSM population in Northern Taiwan. We conducted a 15-year retrospective study by recruiting 207 patients with the diagnosis of acute hepatitis A that included the pre-outbreak (January 2001 to May 2015) and outbreak (June 2015 to August 2016) periods in a tertiary medical center in Northern Taiwan. Using risk factors, comorbidities, presenting symptoms, laboratory test results and imaging data, we aimed to evaluate the clinical significance of acute hepatitis A in the MSM population, where human immunodeficiency virus (HIV) coinfection is common. There was a higher prevalence of reported MSM (p hepatitis A during the outbreak period. The outbreak population had more prominent systemic symptoms, was more icteric with a higher total bilirubin level (p hepatitis A relapse. The clinical course of acute hepatitis A during an outbreak involving the MSM and HIV-positive population is more symptomatic and protracted than in the general population.

    In several Western countries, silent endemic hepatitis E virus (HEV) infection is common among blood donors. Immunocompromised persons may develop chronic hepatitis E, but the relevance of endemic HEV for immunocompetent persons remains largely unknown. We investigated the immune status and travel history in cases of hepatitis E in the Netherlands. Between January 2009 and May 2014, physicians throughout the Netherlands submitted samples from 4067 hepatitis patients to Sanquin Diagnostic Services for HEV antibody testing. For the 144 patients testing positive for HEV IgM and HEV RNA, travel behavior and immune status were assessed. Complete information was obtained for 81 patients. Surprisingly, the majority of patients (52/81, 64%) were immunocompetent and did not travel outside Europe. HEV genotyping was obtained for 47 non-traveling patients, all concerned HEV genotype 3. Our findings suggest that currently in Western countries the impact of hepatitis E for non-traveling, immunocompetent persons is underestimated. Historically cases of hepatitis A, B and C, but not cases of hepatitis E, are notifiable and warrant preventive measures. However, in parts of Western Europe HEV may have become the most important source of viral hepatitis, in immunocompetent and in immunosuppressed persons. Pending measures against the ongoing transmission of HEV genotype 3 in parts of Europe, physicians should consider hepatitis E in dealing with new hepatitis patients. Copyright © 2014 Elsevier B.V.

    Background: While patients with liver disease are known to have a higher prevalence of glucose intolerance, preliminary studies suggest that hepatitis C virus (HCV) infection may be an additional risk factor for the development of diabetes mellitus (DM). Objective: The presented study was aimed to study and determine a relationship between the relative proportions of Diabetes Mellitus in patients suffering from HCV infection. Study Design: This cross sectional study. Study Settings: Patients were registered from outdoor as well as indoor departments of different teaching hospitals (Services hospital Lahore and medical departments in Jinnah hospital, Mayo hospital, Sir Ganga Ram hospital) in Lahore, Pakistan. Methods: This cross sectional study was comprised of age and sex matched 258 patients of viral hepatitis B infection and viral hepatitis C infection, conducted at Hepatitis Clinic Services Hospital, affiliated with Post Graduate Medical Institute, Lahore. Diagnosis of HBV was made with evidence of hepatitis B surface antigen, HCV infection was diagnosed if patient was sero positive for anti HCV (ELISA methods) and HCV - RNA (By PCR). Diabetes Mellitus was diagnosed after fulfilling the American Diabetic Association Criteria, from November, 2000 to September, 2002. Results: A total of 318 patients were registered, out of which 258 cases fulfilled the inclusion criteria, 164 hepatitis C infected and 94 hepatitis B infected cases, 16.46% hepatitis C infected cases were diagnosed as diabetics while 4.25% hepatitis B infected cases were diagnosed as diabetics. Conclusion: This study concludes that there is high Association and relationship of Diabetes Mellitus with Hepatitis C virus infection as compared with Hepatitis B virus infection. (author)

    Hepatitis E virus (HEV) is an emergent virus of global importance; it is the etiological agent of sporadic cases and outbreaks of hepatitis. The epidemiology of this infection in Colombia is unknown. To determine the seropositivity for hepatitis E virus in Colombia in cases with clinical diagnosis of viral hepatitis. Serum samples from patients that were sent to the Instituto Nacional de Salud during the period 2005-2010 (group 1) and samples sent to the Laboratorio Departamental de Salud Pública de Antioquia during the 2008-2009 period were included in this study (group 2). Serum samples were analyzed by immunoassay with commercial kits. From the 344 analyzed samples, 8.7% were positive for anti-HEV; the frequency of anti-HEV IgM was 1.74% (6/344) and the frequency of anti-HEV IgG was 7.5% (26/344). A difference in frequency of anti-HEV between group 1 (6.3%) and group 2 (1.3%) was observed. The cases were identified in nine departments of Colombia. This is the first study of hepatitis E virus infection in patients with diagnosis of hepatitis in Colombia. The frequency of anti-HEV described in this population of patients in Colombia is similar to that described in other Latin American countries like Brazil, Perú and Uruguay. Considering the results of this study, it could be necessary to include hepatitis E virus infection serological markers in the differential diagnosis of viral hepatitis in Colombia.

    Full Text Available Haemophilia is a rare haematological disease characterized by prolonged bleeding due to deficiency of coagulating factor 8 and factor 9. This is cross sectional study carried out at paediatric haematology unit Al-Azhar university hospital, Cairo, Egypt, and paediatric haematology unit of El Mabarah-Hospital-Health Insurance Organization, Zagazig, Egypt, during March 2014 to March 2016. One hundred male patients were screened for hepatitis (A, B, and C. Mean age was 11.47 ± 4.4 years old. About 95% with haemophilia A, 4% haemophilia B and 1 patient had combined haemophilia A and family history of hepatitis was 21%. Consanguinity was 28%. Similar condition in the family was 36%. Ecchymosis as clinical manifestation was 64%, haemarthrosis was 62% and jaundice detected in 35% of cases. Severity was mild 20%, moderate 47% and severe was 33%. Most affected joint was knee joint and represented 41%. Blood transfusion, cryoprecipitate were major risk factors for transmitting of hepatitis C positive cases. HAV was 7%, HBV was 0% and hepatitis C was 65%. Conclusion: HCV is still high in haemophilic and represent a major problem. Recommendation: Early detection, treatment, and further investigation of hepatitis C virus in haemophilic children.

    Acute hepatitis A and E are recognized triggers of hepatic decompensation in patients with cirrhosis, particularly from the Indian subcontinent. However, the resulting acute-on-chronic liver failure (ACLF) has not been well characterized and no large studies are available. Our study aimed to evaluate the clinical profile and predictors of 3-month mortality in patients with this distinctive form of liver failure. ACLF was diagnosed in patients with acute hepatitis A or E [abrupt rise in serum bilirubin and/or alanine aminotransferase with positive immunoglobulin M anti-hepatitis A virus (HAV)/anti-hepatitis E virus (HEV)] presenting with clinical evidence of liver failure (significant ascites and/or hepatic encephalopathy) and clinical, biochemical, endoscopic (oesophageal varices at least grade II in size), ultrasonographical (presence of nodular irregular liver with porto-systemic collaterals) or histological evidence of cirrhosis. Clinical and laboratory profile were evaluated, predictors of 3-month mortality were determined using univariate and multivariate logistic regression and a prognostic model was constructed. Receiver-operating curves were plotted to measure performance of the present prognostic model, model for end-stage liver disease (MELD) score and Child-Turcotte-Pugh (CTP) score. ACLF occurred in 121 (3.75%) of 3220 patients (mean age 36.3+/-18.0 years; M:F 85:36) with liver cirrhosis admitted from January 2000 to June 2006. It was due to HEV in 80 (61.1%), HAV in 33 (27.2%) and both in 8 (6.1%). The underlying liver cirrhosis was due to HBV (37), alcohol (17), Wilson's disease (8), HCV (5), autoimmune (6), Budd-Chiari syndrome (2), haemochromatosis (2) and was cryptogenic in the rest (42). Common presentations were jaundice (100%), ascites (78%) and hepatic encephalopathy (55%). Mean (SD) CTP score was 11.4+/-1.6 and mean MELD score was 28.6+/-9.06. Three-month mortality was 54 (44.6%). Complications seen were sepsis in 42 (31.8%), renal failure in

  15. Epidemiology of zoonotic hepatitis E: a community-based surveillance study in a rural population in China.

    Feng-Cai Zhu

    Full Text Available BACKGROUND: Hepatitis E is caused by two viral genotype groups: human types and zoonotic types. Current understanding of the epidemiology of the zoonotic hepatitis E disease is founded largely on hospital-based studies. METHODS: The epidemiology of hepatitis E was investigated in a community-based surveillance study conducted over one year in a rural city in eastern China with a registered population of 400,162. RESULTS: The seroprevalence of hepatitis E in the cohort was 38%. The incidence of hepatitis E was 2.8/10,000 person-years. Totally 93.5% of the infections were attributed to genotype 4 and the rest, to genotype 1. Hepatitis E accounted for 28.4% (102/359 of the acute hepatitis cases and 68.9% (102/148 of the acute viral hepatitis cases in this area of China. The disease occurred sporadically with a higher prevalence during the cold season and in men, with the male-to-female ratio of 3∶1. Additionally, the incidence of hepatitis E increased with age. Hepatitis B virus carriers have an increased risk of contracting hepatitis E than the general population (OR = 2.5, 95%CI 1.5-4.2. Pre-existing immunity to hepatitis E lowered the risk (relative risk  = 0.34, 95% CI 0.21-0.55 and reduced the severity of the disease. CONCLUSIONS: Hepatitis E in the rural population of China is essentially that of a zoonosis due to the genotype 4 virus, the epidemiology of which is similar to that due to the other zoonotic genotype 3 virus.

    Clinical features of Dengue are very variable due to multiple alterations induced by the virus in the organism. Increased levels of transaminases similar to those produced by the Hepatitis virus have been reported in patients with Dengue from hiperendemic zones in Asia. The objectives of this study were to determine alterations in the liver tests in patients with Dengue and to relate them to the disease, clinically and serologically. Clinical history, hemathological tests serum transaminases (ALT y AST) and bilirubin assays were performed in 62 patients with clinical and serological diagnosis of Dengue. According to clinical features 38.7% of the patients with classical (CD) and hemorrhagic (DHF) forms of Dengue reffered abdominal pain and 2 patients with DHF had ictericia and hepatomegaly. Laboratory test findings showed leucopenia in 72.5% in both forms of Dengue and of patients with DHF severe thrombocytopenia (< 50.000 platelets x mm3), long PT and PPT in 70.9%, 23.0% and 42.3%, respectively. Transaminase values five fold higher than the normal values (p < 0.005) were observed in 36.8% and 74.4% of patients with CD and DHF respectively; AST was predominant in both groups. Our results suggest liver damage during the course of Dengue. A differential diagnosis has to be done between the hepatic involvement of Dengue cases and others viral diseases with hepatic disfunctions.

    Hepatitis A and B vaccines are effective in preventing superinfection and sequelae in patients with chronic hepatitis B or C. We describe immunity and vaccination against hepatitis A and B in chronic hepatitis patients from the US Chronic Hepatitis Cohort Study. We identified chronic hepatitis B and C patients with healthcare utilization during 2006-2008 and 12 months of enrollment. We used electronic laboratory records to determine immunity and medical and billing records for vaccination history. Immunity against hepatitis A was defined by positive hepatitis A antibody or documented vaccination. Immunity against hepatitis B was defined as hepatitis B surface antibody level ≥10 mIU/mL or core antibody positive, or by documented vaccination. Among 1635 chronic hepatitis B patients, 978 (59.8%) were immune or vaccinated against hepatitis A, 122 (7.5%) had negative hepatitis A antibody tests, and 535 (32.7%) had no testing or vaccination record. Among 5328 chronic hepatitis C patients, 2998 (56.3%) were immune or vaccinated against hepatitis A, 659 (12.4%) had negative hepatitis A antibody tests, and 1671 (31.4%) had no testing or vaccination record. Additionally, 3150 (59.1%) chronic hepatitis C patients were immune or vaccinated against hepatitis B, 1003 (18.8%) had a negative test result, and 1175 (22.1%) were neither tested for nor vaccinated against hepatitis B. Approximately 40% of chronic hepatitis B and C patients are susceptible to or have no documented immunity or vaccination against hepatitis A or hepatitis B. Clinicians should consider antibody testing and vaccination for this vulnerable population. © The Author 2014.

    The incidence of hepatitis A infection in the United States has decreased dramatically in recent years because of childhood immunization programs. A decision analysis of the cost-effectiveness of hepatitis A vaccination for adults with hepatitis C was conducted. No vaccination strategy is cost-effective for adults with hepatitis C using the recent lower anticipated hepatitis A incidence, private sector costs, and a cost-effectiveness criterion of $100,000/QALY. Vaccination is cost-effective only for individuals who have cleared the hepatitis C virus when Department of Veterans Affairs costs are used. The recommendation to vaccinate adults with hepatitis C against hepatitis A should be reconsidered. Published by Elsevier Ltd.

    Full Text Available Hepatitis B and hepatitis C viruses (HCV are frequently propagating blood borne pathogens in global community. Viral hepatitis is primarily associated with severe health complications, such as liver cirrhosis, hepatocellular carcinoma, hepatic fibrosis and steatosis. A literature review was conducted on hepatitis B virus (HBV, HBV genome, genotypic distribution and global epidemiology of HBV, HCV, HCV genome, HCV and host immune responses, HCV genotypic distribution and global epidemiology. The valued information was subjected for review. HBV has strict tissue tropism to liver. The virus infecting hepatocytes produces large amount of hepatitis B surface antigen particles which lack the DNA. It has capability to integrate into host genome. It has been found that genotype C is most emerging genotype associated with more severe liver diseases (cirrhosis. The approximate prevalence rate of genotype C is 27.7% which represents a major threat to future generations. Approximately 8% of population is chronic carrier of HBV in developing countries. The chronic carrier rate of HBV is 2%-7% in Middle East, Eastern and Southern Europe, South America and Japan. Among HCV infected individuals, 15% usually have natural tendency to overcome acute viral infection, where as 85% of individuals were unable to control HCV infection. The internal ribosomal entry site contains highly conserved structures important for binding and appropriate positioning of viral genome inside the host cell. HCV infects only in 1%-10% of hepatocytes, but production of tumor necrosis factor alpha (from CD8+ cells and interferon-gamma cause destruction of both infected cells and non-infected surrounding cells. Almost 11 genotypes and above 100 subtypes of HCV exists worldwide with different geographical distribution. Many efforts are still needed to minimize global burden of these infections.

    Full Text Available Hepatitis A virus infection is a global public health problem. The virus has a wide range of distribution and it is the main cause of acute hepatitis transmitted by the enteric route in Latin America. The viral particle is stable under environmental conditions and conserves its infectivity for several weeks, enabling its transmission by contaminated water and food. Worldwide, different epidemiological patterns have been identified, which may change over time by modification of social and economic variables in the population such as vaccination and the improvement of hygiene and primary health conditions. This leaves new populations susceptible to infection. In Latin America the circulation of genotype I and subgenotypes A and B has been described, but more research is needed to provide the knowledge needed to manage the prevention and control plans for the worldwide reduction of the prevalence of infection. For this paper, a literature review was performed on the SciELO, PubMed and ScienceDirect databases under the search terms "Hepatitis A", "Epidemiology," "Seroprevalence" and "Infection." From the results obtained, only papers published in English and Spanish to describe epidemiological and molecular studies of interest in Latin America were included.

    Full Text Available To investigate the role of contrast-enhanced ultrasonography (CEUS and Doppler ultrasonography (DUS in the diagnosis of severe portal hypertension (PH in patients with liver cirrhosis (LC.Patients with PH scheduled to receive hepatic venous pressure gradient (HVPG measurement were recruited for this study. Hepatic DUS and CEUS were performed successively. Several Doppler and CEUS parameters were explored for correlation with HVPG values and their association with severe PH (≥ 12 mmHg of HVPG. Comparison of the parameters between the severe and non-severe PH groups and their correlation with HVPG values was evaluated. A receiver operating characteristic (ROC curve analysis was also performed to investigate the performance in order to diagnose severe PH.Fifty-three consecutive patients were enrolled in this study. Among them, 43 patients did not have significant ascites. Compared with the non-severe PH group, portal venous velocity and intrahepatic transit time (ITT were significantly reduced in the severe PH group (all p<0.05. Difference between inspiratory and expiratory hepatic venous damping indices (ΔHVDI, hepatic venous arrival time (HVAT and ITT moderately correlated with HVPG (r = -0.358, -0.338, and -0.613, respectively. Areas under the curves for severe PH were 0.94 of ITT and 0.72 of HVAT, respectively (all p<0.05. ITT under 6 seconds indicated severe PH with a sensitivity of 92% and a specificity of 89%.Hepatic CEUS may be more useful in estimating the HVPG value and determining the presence of severe PH compared to DUS, and ITT was the most accurate parameter to diagnose severe PH.

    Materials and Methods: In this study, the seropositivity of hepatitis A infection of people who had admitted to Adiyaman University training and research hospital and primary care provider from central regions of Adiyaman city from March 2012 to April 2013 were evaluated, retrospectively. Existence of anti- HAV IgG antibodies were studied by macro ELISA devices belonging two different manufacturers (Abbott Laboratories and Roche Diagnostics. Results: One thousand seven hundred twenty male and 1844 female were included the study (a total of 3564 cases. Anti HAV IgG seropositivity was 77,5% (2761/3564. It was determined that the prevalance was increasing with age. This study found no difference in HAV antibody prevalence between men and women.(p>0,05 Conclusion: Hepatitis A infection's serological prevalence profiles vary geographically in the world. In the intermediate endemic areas like Turkey, the latency in the exposure to the virus has constitute a vast number of susceptible adolescents and extremely increased the average age at infection. The severity of illness increases by age. Implement and not;ing vaccination programs for HAV infection, as well as improved hygiene, sanitation, and drinking water quality and quantity are associated with decreased risk of HAV infection.

    Full Text Available Human hepatic lipase (hHL is mainly localized on the hepatocyte cell surface where it hydrolyzes lipids from remnant lipoproteins and high density lipoproteins and promotes their hepatic selective uptake. Furthermore, hepatic lipase (HL is closely associated with obesity in multiple studies. Therefore, HL may play a key role on lipid homeostasis in liver and white adipose tissue (WAT. In the present study, we aimed to evaluate the effects of hHL expression on hepatic and white adipose triglyceride metabolism in vivo. Experiments were carried out in hHL transgenic and wild-type mice fed a Western-type diet. Triglyceride metabolism studies included β-oxidation and de novo lipogenesis in liver and WAT, hepatic triglyceride secretion, and adipose lipoprotein lipase (LPL-mediated free fatty acid (FFA lipolysis and influx. The expression of hHL promoted hepatic triglyceride accumulation and de novo lipogenesis without affecting triglyceride secretion, and this was associated with an upregulation of Srebf1 as well as the main genes controlling the synthesis of fatty acids. Transgenic mice also exhibited more adiposity and an increased LPL-mediated FFA influx into the WAT without affecting glucose tolerance. Our results demonstrate that hHL promoted hepatic steatosis in mice mainly by upregulating de novo lipogenesis. HL also upregulated WAT LPL and promoted triglyceride-rich lipoprotein hydrolysis and adipose FFA uptake. These data support the important role of hHL in regulating hepatic lipid homeostasis and confirm the broad cardiometabolic role of HL.

    To evaluate the association between insulin resistance and hepatic fibrosis in patients with chronic hepatitis C. A total of 104 chronic hepatitis C patients were included in this non-interventional, open-label, observational, multicenter, cross-sectional study conducted at 20 gastroenterology clinics in Turkey. The primary end point was the correlation between stage of hepatic fibrosis and insulin resistance evaluated via the homeostasis model of assessment-insulin resistance index. Confounders of hepatic fibrosis and insulin resistance were the secondary end points. The mean age of patients was 52.8 years; 65.4% were female. Type 2 diabetes was present in 6.8% and insulin resistance noted in 38.0% of patients. Further, 45.7% of the patients had mild (A0/A1) and the remaining had moderate/severe (A2/A3) hepatic necroinflammatory activity. Patient distribution according to Metavir fibrosis stage was as follows: F0/F1 (57.0%); F2 (6.5%); F3 (23.7%); and F4 (12.9%). A univariate analysis revealed significant positive correlations between Metavir fibrosis stage and insulin resistance (r=0.297; p=0.007). Logistic regression analysis showed that significant predictors of insulin resistance were high alanine transaminase levels (odds ratio, 0.97; 95% confidence interval, 0.944-0.997) and liver fibrosis stage (odds ratio, 0.114; 95% confidence interval, 0.021-0.607). Our findings revealed significant associations between insulin resistance and hepatic fibrosis.

    Feline IHL is a severe hepatopathy that can be treated by aggressive nutritional support. Until the underlying mechanisms of protein and lipid metabolism are understood in both healthy and ill cats, dietary therapy remains supportive. It is likely that the pathogenesis of IHL in cats is multifactorial, involving both increased fatty acid mobilization to the liver and a defect in oxidation of fatty acids or removal of VLDL. It is also possible that individual variation may play a role in the development of this disease in cats undergoing starvation. Continued studies will focus on the unique pathways of hepatic metabolism in the cat, and how these pathways are altered, leading to hepatic lipid accumulation and clinical disease. Hopefully, these studies can be applied to the prevention or treatment of IHL in cats.

    Full Text Available Objective: To study the profile of liver involvement in children with dengue fever and to compare the severity of liver involvement with World Health Organization case definition. Methods: A prospective study was carried out from October 2013 to December 2014. Serologically confirmed dengue patients were grouped into three categories according to the World Health Organization classification. Groups 1 and 2 were dengue fever without and with warning signs, respectively; Group 3 was severe dengue. Biochemical and clinical profile of hepatic involvement was studied. Results: A total of 162 children with dengue fever (M:F = 2.37 were included in the study. Median (inter quartile range age was 12 years (IQR: 0.5–18 years. Hepatitis was observed in 151 (93.2% patients. Analysis revealed that out of all liver function test parameters, total bilirubin was found to be a significant predictor of dengue category two and three and albumin and ALT levels were significant predictors for category three. Eight cases presented with ALF. Their median AST was 4 817 (range 61–26 957; median ALT was 2 386 (range 39–11 100; median INR was 2.57 (range 1.6–4.2 and their median serum bilirubin was 2.95 (range 0.6–9.0. Conclusions: Some degree of hepatitis is very common in dengue infection with rise in AST being more than ALT irrespective of the severity of dengue. Severity of hepatitis correlates well with the severity of dengue and can help in triaging of dengue patients. Of all liver function parameters, total bilirubin levels correlate best with severity of dengue infection.

    To describe the etiology of hepatitis and identify occult hepatitis B virus (HBV) infection. A 40-year-old man presented with severe abdominal pain and jaundice, a history of acute HBV infection that had cleared as well as the use of acetaminophen, methamphetamine, buprenorphine and marijuana. He admitted to having had unprotected sex with multiple partners of both genders. A thorough skin examination revealed papulosquamous lesions on his penis, scrotum, upper and lower extremities and feet. Transaminases and bilirubin were elevated. His rapid plasma reagin was reactive, and hepatitis serologies showed occult HBV. Liver biopsy showed severe hepatitis, but the stains for hepatitis B surface antigen and hepatitis B core antigen were negative. The pathological findings were highly indicative of drug-induced hepatitis without evidence of chronic hepatitis, reactivation of HBV or syphilitic hepatitis. With supportive management and abstinence from drugs, his condition improved. This case describes a patient with multiple potential causes for hepatitis and highlights the importance of obtaining a detailed social history. Further, one should consider the presence of occult HBV and recognize the serologic pattern. © 2014 S. Karger AG, Basel.

    Objective: To assess CT manifestations and diagnostic value in patients with hepatic tuberculosis. Methods: Ten cases of hepatic tuberculosis proved by hepatic biopsy or surgical specimens were analyzed retrospectively. Results: This group of hepatic tuberculosis included three types. (1) Five cases of miliary hepatic tuberculosis demonstrated that the liver swelled diffusely associated with multiple miliary low attenuations, and showed no enhancement after contrast agents administration. (2) Three cases of tubercle hepatic tuberculosis depicted multiple hypodensity areas or mixed density regions in the liver. The extension of lesions reduced in arterial phase, and a ring-like enhancement was displayed in the portal phase. (3) One case of hepatic tuberculoma illustrated solitary space occupying lesion accompanied with central necrosis. The envelope was thin and smooth which enhanced slightly after injecting Gd-DTPA. Another one was hepatic abscess and depicted fluid-fluid level inside the lesion. Conclusions: The CT manifestations of miliary hepatic tuberculosis lack of characteristics, it is hard to make the diagnosis clear-cut unless integrating the medical history and lab test. The 'powder calcification' findings of tubercle hepatic tuberculosis is propitious to draw a qualitative diagnosis. And the feature of hepatic tuberculomas with fluid- fluid level is in favor of making a differential diagnosis against parallel tumors. (authors)

    Objective: To evaluate the clinical efficacy of transcatheter hepatic arterial thermo-chemotherapy and thermo-lipiodol embolization in the treatment of hepatic metastases from colorectal carcinoma. Methods: Sixty-eight cases with hepatic metastases from colorectal carcinoma were equally and randomly divided into two groups. The patients in study group were treated with transcatheter hepatic arterial thermo-chemotherapy and thermo-lipiodol embolization, while the patients in control group were treated with conventional (normal temperature) transcatheter hepatic arterial chemotherapy lipiodol embolization. Results: The effective rate of study group and control group was 65%(22/34) and 32%(11/34) respectively, the difference between two groups was statistically significant (P<0.05). No significant difference in the postoperative changes of hepatic function tests was found between the two groups. The survival rate at 6,12,18 and 24 months after the treatment was 100%, 82%, 44% and 18% respectively in study group, while it was 91%, 47%, 15% and 6% respectively in control group. Conclusion: Transcatheter hepatic arterial thermo-chemotherapy and thermo-lipiodol embolization is an effective and safe treatment for the hepatic metastases from colorectal carcinoma and has no obvious damage to the hepatic function.

    Objective: To study the normal angiographic anatomy and variations of rabbit hepatic vessels, and explore the optimal method for hepatic artery catheterization. Methods: 30 rabbits were divided into two groups randomly. Modified surgical method and interventional method were used to catheterize hepatic artery respectively, and followed by angiography to demonstrate the normal anatomy and variations of rabbit celiac artery, hepatic artery and portal vein. Results: The route and distribution of rabbit celiac artery and hepatic artery were very different from human's. The commonly seen variation showed the differences in branching bifurcation of hepatic-gastric artery, with the incidence of 13.3%. The rates of successfully hepatic artery catheterization with surgical and interventional methods were 86.6%(13/15) and 80%(12/15) respectively (P>0.05). The surgical method will not be successful, whenever there's variation. Conclusion: The normal anatomy and variation of rabbit celiac artery and hepatic artery are quite different from human's. Both surgical and interventional catheterizations could be rather successful but possessing advantages and disadvantages of each its own. (authors)

    Objective: To discuss the method, mid-long term clinical therapeutic effect and safety of coil embolization in treating patients with hepatic arterial pseudoaneurysm (HAPA). Methods: Seven patients with repeatedly massive hemorrhage of gastrointestinal tract were undertaken DSA of celiac arteries and hepatic arteries and embolization of the feeding artery by coils or microcoils after correct diagnosis. All cases underwent follow-up from 6 to 60 months(mean 38). Results: The blood loss before angiography was ranged from 1200 to 4 000 (mean 2 385) ml. There were 3 cases with normal hepatic function and 4 with hepatic dysfunction including ALT increase in 2 and obstructive jaundice in another. Digital substraction angiography (DSA) clearly showed the location, shape and feeding arteries of HAPA. There were 2 types of HAPA namely intrahepatic (n=3)and extrahepatic (n=4), adding one case with arteriovenous fistula (AVF). Embolization was successful in all cases by coils (n=13) or microcoils (n=12). No recurrence and any definite clinical complication occurred during follow-up. Conclusion: Coil embolization in treating HAPA is safe and effective with mid-long term positive clinical therapeutic efficiency without severe complications. (authors)

  4. Clinical relevance of precore mutations of hepatitis B virus in chronic liver disease

    Directory of Open Access Journals (Sweden)

    Chaloska-Ivanova Viktorija

    2014-07-01

    Full Text Available Introduction: Hepatitis B is one of the most frequent etiological factors for chronic liver diseases worldwide. Recent studies have suggested the important role of the genetic diversity of the virus on natural course of hepatitis B. Hepatitis B e-antigen negative type of chronic hepatitis is associated with mutations in the precore region and basic core promoter of hepatitis B viral genome. Aim of study was to identify precore mutations in viral genome of patients with chronic hepatitis B and to evaluate clinical patterns of liver disease related to this type of hepatitis B. Methods: Sixty seven patients with hepatitis B were included in the study. In order to evaluate the clinical patterns of chronic liver disease related to hepatitis B viral infection, biochemical and virological investigations were done, as well as a quantification of serum viral load. All patients underwent liver biopsy and semiquantification of necroinflammation and/or fibrosis according to Knodell scoring was done. In the group of e antigen-negative patients, molecular analysis was performed in order to identify presence of mutations in precore region of the virus. Results: Study group was divided in 25 HBeAg-positive and 42 HBeAg-negative subjects. Al anin-aminotransferase activity and level of viral load were higher in HBeAg-positive (p < 0.05, but average age and histology activity index were significantly higher in the HBeAg-negative patients (p < 0.01. Precore mutants were found in 38 of 42 patients with HBeAg-negative hepatitis (90%. Fibrosis was found in 30/38 cases with mutations. Discussion: Mutations in precore region of HBV in HBeAg-negative patients were more prevalent in older age and were associated with higher rate of fibrosis in liver tissue, meaning more advanced stage of the disease. This could be a consequence of longer duration of HBV infection or more severe clinical course of the disease. Conclusion: Our results suggest that precore mutations are

  5. Angiogenesis alteration by defibrotide: implications for its mechanism of action in severe hepatic veno-occlusive disease.

    Defibrotide (DF) is a mixture of porcine-derived single-stranded phosphodiester oligonucleotides (9-80-mer; average, 50-mer) that has been successfully used to treat severe hepatic veno-occlusive disease (sVOD) with multiorgan failure (MOF) in patients who have received cytotoxic chemotherapy in preparation for bone marrow transplantation. However, its mechanism of action is unknown. Herein, we show that DF and phosphodiester oligonucleotides can bind to heparin-binding proteins (eg, basic fibroblast growth factor [bFGF] but not vascular endothelial growth factor [VEGF] 165) with low nanomolar affinity. This binding occurred in a length- and concentration-dependent manner. DF can mobilize proangiogenic factors such as bFGF from their depot or storage sites on bovine corneal endothelial matrix. However, these molecules do not interfere with high-affinity binding of bFGF to FGFR1 IIIc but can replace heparin as a required cofactor for binding and hence cellular mitogenesis. DF also protects bFGF against digestion by trypsin and chymotrypsin and from air oxidation. In addition, DF binds to collagen I with low nanomolar affinity and can promote human microvascular endothelial cell-1 (HMEC-1) cell mitogenesis and tubular morphogenesis in three-dimensional collagen I gels. Thus, our data suggest that DF may provide a stimulus to the sinusoidal endothelium of a liver that has suffered a severe angiotoxic event, thus helping to ameliorate the clinical sVOD/MOF syndrome.

    2017-09-01

    Hepatitis A virus is one of the most frequent causes of foodborne infection, which is closely associated with sanitary conditions and hygienic practices. The clinical spectrum of acute hepatitis A is wide, ranging from mild case without any noticeable symptoms to severe case with acute liver failure leading to mortality. The severity and outcome are highly correlated with age at infection. In developing countries, most people are infected in early childhood without significant symptom. Ironically, in area where sanitary condition has improved rapidly, adults who do not have immunity for viral hepatitis A (VH-A) in early childhood is accumulating. Adults without immunity are exposed to risks of symptomatic disease and large outbreaks in society. In Korea, where hygiene has improved rapidly, acute hepatitis A is a significant health burden that needs to be managed with nationwide health policy. The incidence of symptomatic VH-A has increased since 2000 and peaked in 2009. Korea has designated hepatitis A as a group 1 nationally notifiable infectious disease in 2001. Since 2001, mandatory surveillance system has been established to detect every single case of acute hepatitis A. Universal, nationwide vaccination program for newborns was introduced in 2015. In this review, we will present the current epidemiologic status of viral hepatitis A, and evaluate the effectiveness of the current nationwide strategies for the control of viral hepatitis A in Korea. Furthermore, we presented some action proposals that can help eliminate viral hepatitis A, which is a significant health burden in Korea.

    Several studies have shown that protectins, which are ω-3 fatty acid-derived proresolution mediators, may improve insulin resistance. Recently, protectin DX (PDX) was documented to attenuate insulin resistance by stimulating IL-6 expression in skeletal muscle, thereby regulating hepatic gluconeogenesis. These findings made us investigate the direct effects of PDX on hepatic glucose metabolism in the context of diabetes. In the current study, we show that PDX regulates hepatic gluconeogenesis in a manner distinct from its indirect glucoregulatory activity via IL-6. We found that PDX stimulated AMP-activated protein kinase (AMPK) phosphorylation, thereby inducing heme oxygenase 1 (HO-1) expression. This induction blocked hepatic gluconeogenesis by suppressing endoplasmic reticulum (ER) stress in hepatocytes under hyperlipidemic conditions. These effects were significantly dampened by silencing AMPK or HO-1 expression with small interfering RNA (siRNA). We also demonstrated that administration of PDX to high fat diet (HFD)-fed mice resulted in increased hepatic AMPK phosphorylation and HO-1 expression, whereas hepatic ER stress was substantially attenuated. Furthermore, PDX treatment suppressed the expression of gluconeogenic genes, thereby decreasing blood glucose levels in HFD-fed mice. In conclusion, our findings suggest that PDX inhibits hepatic gluconeogenesis via AMPK-HO-1-dependent suppression of ER stress. Thus, PDX may be an effective therapeutic target for the treatment of insulin resistance and type 2 diabetes through the regulation of hepatic gluconeogenesis. Copyright © 2017 Elsevier Inc.

    The human hepatitis B virus causes acute and chronic hepatitis and is considered one of the most serious human health issues by the World Health Organization, causing thousands of deaths per year. There are similar viruses belonging to the Hepadnaviridae family that infect non-human primates and other mammals as well as some birds. The majority of non-human primate virus isolates were phylogenetically close to the human hepatitis B virus, but like the human genotypes, the origins of these viruses remain controversial. However, there is a possibility that human hepatitis B virus originated in primates. Knowing whether these viruses might be common to humans and primates is crucial in order to reduce the risk to humans. To review the existing knowledge about the evolutionary origins of viruses of the Hepadnaviridae family in primates. This review was done by reading several articles that provide information about the Hepadnaviridae virus family in non-human primates and humans and the possible origins and evolution of these viruses. The evolutionary origin of viruses of the Hepadnaviridae family in primates has been dated back to several thousand years; however, recent analyses of genomic fossils of avihepadnaviruses integrated into the genomes of several avian species have suggested a much older origin of this genus. Some hypotheses about the evolutionary origins of human hepatitis B virus have been debated since the '90s. One theory suggested a New World origin because of the phylogenetic co-segregation between some New World human hepatitis B virus genotypes F and H and woolly monkey human hepatitis B virus in basal sister-relationship to the Old World non-human primates and human hepatitis B virus variants. Another theory suggests an Old World origin of human hepatitis B virus, and that it would have been spread following prehistoric human migrations over 100,000 years ago. A third theory suggests a co-speciation of human hepatitis B virus in non-human primate

The literature was searched for publications on severe hepatitis caused by terbinafine using MEDLINE, China Biology Medicine Disc, and the VIP Medical Information Resource System. Related references were searched manually. Seventeen English and three Chinese references of case reports were included after eliminating duplicate publications. No randomized control studies were found. Liver enzyme levels were found to have been increased significantly. Abdominal ultrasound demonstrated cholestasis. Severe acute liver injury is a known, but unusual complication of terbinafine exposure. The prognosis is often good with appropriate treatment. Liver function assessment before treatment and periodic monitoring 4-6 weeks after initiation of treatment is recommended.

    We report a 61-year-old woman who was hospitalized because of abdominal pain in the right upper quadrant related to a liver tumor (ultrasound and tomographic findings). A collection of blood was obtained by a biopsy and there were no tumor cells. With the suspicion of acute fascioliasis (liver stage), due to severe eosinophilia and recent travel to endemic area of Fasciola hepatica, arc II and ELISA Fas 2 we carried out and were positive. Parasitological stool examinations were negative. During hospitalization a hepatic subcapsular hematoma presented as a complication and the patient developed fever because of cholangiolitic microabscesses in the left hepatic lobe. Percutaneous drainage was performed and positive cultures of secretions were obtained She received antibiotic coverage with vancomycin and imipenem. Treatment for Fasciola hepatica was initiated with nitaxozanida but it was discontinued due to oral intolerance. Later, she received a single dose of 250 mg triclabendazole with clinical and laboratory improvement. We presented this case because it is an unusual pseudotumoral presentation in acute hepatic fascioliasis. This parasitic disease is an emerging zoonosis in Perú.

    2018-01-01

    Full Text Available Biliary obstruction, a severe cholestatic complication, causes accumulation of toxic bile acids (BAs in liver cells. Glucuronidation, catalyzed by UDP-glucuronosyltransferase (UGT enzymes, detoxifies cholestatic BAs. Using liquid chromatography coupled to tandem mass spectrometry, 11 BA glucuronide (-G species were quantified in prebiliary and postbiliary stenting serum and urine samples from 17 patients with biliary obstruction. Stenting caused glucuronide- and fluid-specific changes in BA-G levels and BA-G/BA metabolic ratios. In vitro glucuronidation assays with human liver and kidney microsomes revealed that even if renal enzymes generally displayed lower KM values, the two tissues shared similar glucuronidation capacities for BAs. By contrast, major differences between the two tissues were observed when four human BA-conjugating UGTs 1A3, 1A4, 2B4, and 2B7 were analyzed for mRNA and protein levels. Notably, the BA-24G producing UGT1A3 enzyme, abundant in the liver, was not detected in kidney microsomes. In conclusion, the circulating and urinary BA-G profiles are hugely impacted under severe cholestasis. The similar BA-glucuronidating abilities of hepatic and renal extracts suggest that both the liver and kidney may contribute to the urine BA-G pool.

    Two hundred seventy-four children were examined with CT after incurring blunt trauma to the abdomen. Hepatic and/or splenic injuries were detected in 36 patients. Of 12 children with moderate to severe hepatic injuries, only one required operative intervention. Of 13 children with moderate to sever splenic injuries, only one required splenorrhaphy. Only two of 16 patients with a moderate to large hemoperitoneum required surgery for hepatic or splenic injury. The authors conclude that the decision for laparotomy should not be based on the extent of injury as seen on CT, but on the physiologic condition of the child

    To determine a highly specific liver attenuation threshold at unenhanced CT for biopsy-proven moderate to severe hepatic steatosis ({>=}30% at histology). 315 asymptomatic adults (mean age {+-} SD, 31.5 {+-} 10.1 years; 207 men, 108 women) underwent same-day unenhanced liver CT and ultrasound-guided liver biopsy. Blinded to biopsy results, CT liver attenuation was measured using standard region-of-interest methodology. Multiple linear regression analysis was used to assess the relationship of CT liver attenuation with patient age, gender, BMI, CT system, and hepatic fat and iron content. Thirty-nine subjects had moderate to severe steatosis and 276 had mild or no steatosis. A liver attenuation threshold of 48 HU was 100% specific (276/276) for moderate to severe steatosis, with no false-positives. Sensitivity, PPV and NPV at this HU threshold was 53.8%, 100% and 93.9%. Hepatic fat content was the overwhelming determinant of liver attenuation values, but CT system (P < 0.001), and hepatic iron (P = 0.035) also had a statistically significant independent association. Unenhanced CT liver attenuation alone is highly specific for moderate to severe hepatic steatosis, allowing for confident non-invasive identification of large retrospective/prospective cohorts for natural history evaluation of incidental non-alcoholic fatty liver disease. Low sensitivity, however, precludes effective population screening at this threshold. (orig.)

    Objective: The knowledge on Helicobacter pylori (H. pylori) contribution in the pathology of the liver and biliary tract diseases in human is very limited. The aim of this study was to assess the probable association between H. pylori seropositivity and hepatic encephalopathy. Methodology: This is a case control study conducted through three groups, cirrhotics with hepatic encephalopathy (HE), cirrhotics without HE and healthy controls. All subjects were examined serologically for determination of IgG class antibodies to H. pylori based on ELISA technique. Results: H. pylori seropositivity was present in 88% cirrhotic patients with hepatic encephalopathy, 86% cirrhotics without hepatic encephalopathy and 66% healthy controls. Conclusion: According to our results, H. pylori seropositivity rate in cirrhotic patients with or without hepatic encephalopathy was higher than healthy controls. But H. pylori seropositivity rate was not significantly different among cirrhotics with hepatic encephalopathy and those without it.

    Liver transplantation is the ultimate treatment for severe hepatic failure to date. However, the limited supply of donor organs has severely hampered this treatment. So far, great potentials of using mesenchymal stem cells (MSCs) to replenish the hepatic cell population have been shown; nevertheless, there still is a lack of an optimal three-dimensional scaffold for generation of well-transplantable hepatic tissues. In this study, we utilized a cryo-chemical decellularization method which combines physical and chemical approach to generate acellular liver scaffolds (ALS) from the whole liver. The produced ALS provides a biomimetic three-dimensional environment to support hepatic differentiation of MSCs, evidenced by expression of hepatic-associated genes and marker protein, glycogen storage, albumin secretion, and urea production. It is also found that hepatic differentiation of MSCs within the ALS is much more efficient than two-dimensional culture in vitro. Importantly, the hepatic-like tissues (HLT) generated by repopulating ALS with MSCs are able to act as functional grafts and rescue lethal hepatic failure after transplantation in vivo. In summary, the cryo-chemical method used in this study is suitable for decellularization of liver and create acellular scaffolds that can support hepatic differentiation of MSCs and be used to fabricate functional tissue-engineered liver constructs.

    2017-01-01

    Full Text Available High hepatitis C virus (HCV genetic diversity impacts infectivity/pathogenicity, influencing chronic liver disease progression associated with fibrosis degrees and hepatocellular carcinoma. HCV core protein is crucial in cell-growth regulation and host-gene expression. Liver fibrosis is accelerated by unknown mechanisms in human immunodeficiency virus-1- (HIV-1- coinfected individuals. We aimed to study whether well-defined HCV-1a core polymorphisms and genetic heterogeneity are related to fibrosis in a highly homogeneous group of interferon-treated HIV-HCV-coinfected patients. Genetic heterogeneity was weighed by Faith’s phylogenetic diversity (PD, which has been little studied in HCV. Eighteen HCV/HIV-coinfected patients presenting different liver fibrosis stages before anti-HCV treatment-initiation were recruited. Sampling at baseline and during and after treatment was performed up to 72 weeks. At inter/intrahost level, HCV-1a populations were studied using molecular cloning and Sanger sequencing. Over 400 complete HCV-1a core sequences encompassing 573 positions of C were obtained. Amino acid substitutions found previously at positions 70 and 91 of HCV-1b core region were not observed. However, HCV genetic heterogeneity was higher in mild than in severe fibrosis cases. These results suggest a potential utility of PD as a virus-related factor associated with chronic hepatitis C progression. These observations should be reassessed in larger cohorts to corroborate our findings and assess other potential covariates.

    The liver is the intra-abdominal organ more injured in patient victims of trauma. The injury occurs more frequently in the penetrating trauma. The incidence of mortality for injuries of the liver is 10%. To evaluate the mortality of the patients with hepatic trauma, the treatment applied and its evolution. Were analyzed, retrospectively, the charts of all patients with hepatic trauma and surgical indication. Were analyzed: gender, age, ISS (injury severity score), classification of the abdominal trauma type (open or closed), causing instrument of the open traumas, degree of the injury, hepatic segments involved, presence of associated injuries, type of surgical treatment: not-therapeutic laparotomy and therapeutic laparotomy, reoperations, complications, time of hospitalization in days and mortality. One hundred and thirty-seven patients participated. Of these, 124 were men (90.5%). The majority (56.2%) had 20-29 years old. Closed abdominal trauma was most prevalent (67.9%). Of the penetrating traumas, the originated with firearms were in 24.8%. One hundred and three patients had only one injured hepatic segment (75.2%) and 34 (24.8%) two. Grade II injuries were in 66.4%. Of the 137 patients with laparotomy, 89 had been not-therapeutic, while in 48 it was necessary to repair associated injuries. Spleen and diaphragm had been the more frequently injured structures, 30% and 26%, respectively. The ISS varied of eight to 72, being the ISS > 50 (eight patients) associate with fatal evolution (five patients). Biliary fistula and hepatic abscess had been the main complications. Seven deaths had occurred. Concomitant injuries, hepatic and other organs, associated with ISS > 50 presented higher possibility of complications and death.

    To determine the frequency of hepatitis B and C virus infection among children with beta thalassemia major registered at Military Hospital Rawalpindi. Children attending Thalassemia Centre Military Hospital Rawalpindi for regular blood transfusion were registered. They belonged to different ethnic groups and came from different parts of the country. Their demographic data was recorded, detailed history taken and physical examination was carried out. Their serum samples were tested for hepatitis B surface antigen and anti HCV antibody assay with third generation commercial ELISA method. During the study; 141 patients of beta thalassemia major were screened. Out of them 50 patients (35.5% ,95% confidence interval 27.8-43.5)w ere found hepatitis C virus antibody positive and 1 patient (0.7 %) hepatitis B surface antigen positive. One patient (0.7%) had both hepatitis B and C virus infection. Mean age of hepatitis C infected patients was 10.4+3.85y ears (range 2-16 years). Mean age of uninfected patients was 6.1 + 3.59 years. (p value 0.000) In addition, the results indicate that higher prevalence of anti-HCV was significantly associated with longer duration of transfusion (p value <0.003). In spite of the fact that screened blood is used for transfusions, still a large number of patients have been found infected with hepatitis C. Therefore more accurate techniques are required for screening of blood to prevent transfusion associated transmission. (author)

    Full Text Available Hepatitis B virus (HBV tends to mutate easily due to its special structure and life cycle. Mutation changes the biological behavior of HBV and its sensitivity to antiviral drugs and even affects therapeutic effect and accelerate disease progression. The point mutations are commonly see in the pre-S/S open reading frame (ORF, which may be associated with immune escape and occult HBV infection. The G1896A mutation is often observed in the pre-C/C-ORF and is associated with the development of HBeAg-negative chronic hepatitis B (CHB, hepatocellular carcinoma (HCC, and severe chronic hepatitis (liver failure. The mutations in P-ORF mainly occur in the reverse transcriptase (RT domain and are closely related to the resistance to nucleos(tide analogues. The A1762T and G1764A mutations occur in the basal core promoter (BCP, which overlaps with X-ORF, and may be associated with HBeAg-negative CHB, HCC, and severe chronic hepatitis (liver failure. Clarification of the association between these mutations and diseases helps to develop tailor-made diagnostic and therapeutic regimens for patients with HBV infection.

    Dairy cows with fatty liver are characterized by hepatic lipid accumulation and a severe inflammatory response. Sterol receptor element binding protein-1c (SREBP-1c) and nuclear factor κB (NF-κB) are components of the main pathways for controlling triglyceride (TG) accumulation and inflammatory levels, respectively. A previous study demonstrated that hepatic inflammatory levels are positively correlated with hepatic TG content. We therefore speculated that SREBP-1c might play an important role in the overactivation of the hepatic NF-κB inflammatory pathway in cows with fatty liver. Compared with healthy cows, cows with fatty liver exhibited severe hepatic injury and high blood concentrations of the inflammatory cytokines TNF-α, IL-6 and IL-1β. Hepatic SREBP-1c-mediated lipid synthesis and the NF-κB inflammatory pathway were both overinduced in cows with fatty liver. In vitro, treatment with non-esterified fatty acids (NEFA) further increased SREBP-1c expression and NF-κB pathway activation, which then promoted TG and inflammatory cytokine synthesis. SREBP-1c overexpression overactivated the NF-κB inflammatory pathway in hepatocytes by increasing ROS content and not through TLR4. Furthermore, SREBP-1c silencing decreased ROS content and further attenuated the activation of the NEFA-induced NF-κB pathway, thereby decreasing TNF-α, IL-6 and IL-1β synthesis. SREBP-1c-overexpressing mice exhibited hepatic steatosis and an overinduced hepatic NF-κB pathway. Taken together, these results indicate that SREBP-1c enhances the NEFA-induced overactivation of the NF-κB inflammatory pathway by increasing ROS in cow hepatocytes, thereby further increasing hepatic inflammatory injury in cows with fatty liver.

  9. Obesity-induced hepatic hypoperfusion primes for hepatic dysfunction after resuscitated hemorrhagic shock.

    Obese patients (BMI>35) after blunt trauma are at increased risk compared to non-obese for organ dysfunction, prolonged hospital stay, infection, prolonged mechanical ventilation, and mortality. Obesity and non-alcoholic fatty liver disease (NAFLD) produce a low grade systemic inflammatory response syndrome (SIRS) with compromised hepatic blood flow, which increases with body mass index. We hypothesized that obesity further aggravates liver dysfunction by reduced hepatic perfusion following resuscitated hemorrhagic shock (HEM). Age-matched Zucker rats (Obese, 314-519 g & Lean, 211-280 g) were randomly assigned to 4 groups (n = 10-12/group): (1) Lean-Sham; (2) Lean, HEM, and resuscitation (HEM/RES); (3) Obese-Sham; and (4) Obese-HEM/RES. HEM was 40% of mean arterial pressure (MAP) for 60 min; RES was return of shed blood/5 min and 2 volumes of saline/25 min. Hepatic blood flow (HBF) using galactose clearance, liver enzymes and complete metabolic panel were measured over 4 h after completion of RES. Obese rats had increased MAP, heart rate, and fasting blood glucose and BUN concentrations compared to lean controls, required less blood withdrawal (mL/g) to maintain 40% MAP, and RES did not restore BL MAP. Obese rats had decreased HBF at BL and during HEM/RES, which persisted 4 h post RES. ALT and BUN were increased compared to Lean-HEM/RES at 4 h post-RES. These data suggest that obesity significantly contributes to trauma outcomes through compromised vascular control or through fat-induced sinusoidal compression to impair hepatic blood flow after HEM/RES resulting in a greater hepatic injury. The pro-inflammatory state of NAFLD seen in obesity appears to prime the liver for hepatic ischemia after resuscitated hemorrhagic shock, perhaps intensified by insidious and ongoing hepatic hypoperfusion established prior to the traumatic injury or shock.

    Full Text Available Background: the efficacy of combination therapy with peginterferon plus ribavirin to eradicate viral infection in patients with chronic hepatitis C (CHC is well established; moreover, it is able to arrest or even reverse liver fibrosis. Aims: to analyze the measurements of hepatic stiffness as an index of liver fibrosis using transient elastography (TE in patients who underwent a sustained virological response (SVR during long-term follow-up; comparing the changes in the severity of fibrosis with non-responders patients. Material and methods: after hepatic fibrosis was studied in three patients with CHC who underwent a SVR during long-term follow up, a prospective study was initiated in 24 patients with CHC who received combination therapy to compare the evolution of fibrosis in those with SVR and those who were non-responders. The genotype of hepatitis C virus (HCV and the degree of viremia were determined. METAVIR scoring system was used for liver fibrosis. Hepatic stiffness was measured by TE. Results: of the initial three patients pre-treatment liver biopsies revealed active disease and fibrosis (stage 3 in two and mild fibrosis (stage 1 in one. After several years of follow up serum AST/ALT levels were normal and HCV RNA was undetectable in each case; in contrast to the baseline histological assessments of fibrosis, values for hepatic stiffness (3.4-6.9 KPa were compatible with an absence of any appreciable hepatic fibrosis. In the prospective study, 8 patients underwent a SVR and 16 were non-responders. TE indicated that the severity of hepatic fibrosis in the SVR group improved in 7 (88% patients, whereas in the non-responder it improved in only 4 (25% (p < 0.05. The difference between development of severe fibrosis (F ≥ 3 in responders and non-responders was not significant (p = 0.23, possibly due to the small sample size. Conclusions: regression of hepatic fibrosis appears to be common in patients with CHC who undergo a SVR. TE is a

    Full Text Available Objective To analyze the correlation between malnutrition and prognosis in Uyghur pediatric patients with hepatitis A in Hetian of Xinjiang Uyghur Autonomous Region, China. Methods The clinical data of 342 children with hepatitis A admitted to the Infectious Disease Hospital of Hetian from January 2014 to May 2015 were retrospectively analyzed and the patients were divided into malnutrition group with 136 patients and normal nutrition group with 206 patients according to the Z-scores. The data of complete blood count, liver function test, biochemical indices, blood lipids, blood coagulation, and hospitalization days and costs were compared between the two groups. Comparison of categorical data between the two groups was made by chi-square test and comparison of continuous data between the two groups was made by t test. Results Compared with the normal nutrition group, the malnutrition group had significantly lower values of breastfeeding rate, hemoglobin, mean corpuscular volume, mean corpuscular hemoglobin, mean corpuscular hemoglobin concentration, serum iron, serum ferritin, glucose, serum albumin, and plasma thromboplastin antecedent but higher values of alanine transaminase, total bilirubin, total bile acid, cholesterol, and hospitalization days and costs (P<0.05. Conclusion Compared with the normal nutrition pediatric patients with hepatitis A, the malnutrition pediatric patients with hepatitis A have more severe iron deficiency anemia, hepatic damage, and abnormal metabolism of carbohydrates and fatty acids, so their recovery time is longer and the hospitalization costs are higher. To effectively protect Uygur children, hepatitis A vaccination in due course and the children′s growth and development monitoring are recommended.

    A yeast-recombinant hepatitis B vaccine was licensed recently by the Food and Drug administration and is now available. To assess the efficacy of the yeast-recombinant vaccine, the authors administered the vaccine in combination with hepatitis B immune globulin to high-risk newborns. If infants whose mothers were positive for both hepatitis B surface antigen and the e antigen receive no immunoprophylaxis, 70% to 90% become infected with the virus, and almost all become chronic carriers. Among infants in this study who received hepatitis B immune globulin at birth and three 5- + g doses of yeast-recombinant hepatitis B vaccine, only 4.8% became chronic carriers, a better than 90% level of protection and a rate that is comparable with that seen with immune globulin and plasma-derived hepatitis B vaccine. Hepatitis surface antigen and antibodies were detected by radioimmunoassay. These data suggest that, in this high-risk setting, the yeast-recombinant vaccine is as effective as the plasma-derived vaccine in preventing hepatitis B virus infection and the chronic carrier state

    PLA2G6 or GVIA calcium-independent PLA2 (iPLA2β) is identified as one of the NAFLD modifier genes in humans, and thought to be a target for NAFLD therapy. iPLA2β is known to play a house-keeping role in phospholipid metabolism and remodeling. However, its role in NAFLD pathogenesis has not been supported by results obtained from high-fat feeding of iPLA2β-null (PKO) mice. Unlike livers of human NAFLD and genetically obese rodents, fatty liver induced by high-fat diet is not associated with depletion of hepatic phospholipids. We therefore tested whether iPLA2β could regulate obesity and hepatic steatosis in leptin-deficient mice by cross-breeding PKO with ob/ob mice to generate ob/ob-PKO mice. Here we observed an improvement in ob/ob-PKO mice with significant reduction in serum enzymes, lipids, glucose, insulin as well as improved glucose tolerance, and reduction in islet hyperplasia. The improvement in hepatic steatosis measured by liver triglycerides, fatty acids and cholesterol esters was associated with decreased expression of PPARγ and de novo lipogenesis genes, and the reversal of β-oxidation gene expression. Notably, ob/ob livers contained depleted levels of lysophospholipids and phospholipids, and iPLA2β deficiency in ob/ob-PKO livers lowers the former, but replenished the latter particularly phosphatidylethanolamine (PE) and phosphatidylcholine (PC) that contained arachidonic (AA) and docosahexaenoic (DHA) acids. Compared with WT livers, PKO livers also contained increased PE and PC containing AA and DHA. Thus, iPLA2β deficiency protected against obesity and ob/ob fatty liver which was associated with hepatic fatty-acyl phospholipid remodeling. Our results support the deleterious role of iPLA2β in severe obesity associated NAFLD. Copyright © 2016 Elsevier B.V. All rights reserved.

    TIPS is an interventional radiologic method of creating a portosystemic shunt by percutaneous means. It is a relatively new weapon in the armamentarium of the management of portal hypertension with variceal bleeding or intractable ascites. Using needles, angioplasty balloon catheters and expandable metallic stents, a shunt is established directly inside the liver parenchyma connecting a large hepatic vein with a main portal vein branch. Depending on the diameter of the expandable stent used, the created TIPS diverts various amounts of portal blood into the systemic circulation and results in significant portal decompression, cessation of hemorrhage from esophageal varices and resolution of ascites. TIPS is not only an effective and safe alternative to shunt surgery but is life saving in cases of variceal hemorrhage. The use of TIPS seems to be a valid alternative to surgery and has several advantages over either esophageal transection or surgical shunts. TIPS avoids a general anesthetic, laparotomy, and disruption of the hepatic venous system that may adversely affect subsequent hepatic transplantation. TIPS has been performed on patients without interfering with successful transplantation

    Nonalcoholic fatty liver disease (NAFLD) including nonalcoholic steatohepatitis (NASH) is globally increasing and has become a world-wide health problem. Chronic infection with hepatitis B virus or hepatitis C virus (HCV) is associated with hepatic steatosis. Viral hepatitis-associated hepatic steatosis is often caused by metabolic syndrome including obesity, type 2 diabetes mellitus and/or dyslipidemia. It has been reported that HCV genotype 3 exerts direct metabolic effects that lead to hepatic steatosis. In this review, the differences between NAFLD/NASH and viral hepatitis-associated steatosis are discussed.

    nuclear extracts of liver homogenates. Moreover, CORM-2 treatment resulted in reduced serum levels of pro-inflammatory cytokines TNF-α and IL-6 and down-regulation of the adhesion molecule ICAM-1 in the endothelial cells of liver. In line with these findings, CORM-2 treatment reduced the accumulation of neutrophils in the liver upon I/Ri. Similar treatment with an inactive variant of CORM-2 (iCORM-2 did not have any beneficial effect on the extent of liver I/Ri. Conclusions CORM-2 treatment at the time of reperfusion had several distinct beneficial effects on severity of hepatic I/Ri that may be of therapeutic value for the prevention of tissue damage as a result of I/Ri during hepatic surgery.

    Background In low hepatitis B virus (HBV)-prevalent countries, most HBV-infected persons are unaware of their status. We aimed to evaluate whether (i) previous HBV-testing, (ii) physicians decision to screen, and (iii) CDC's recommendations identified infected individuals and which risk-factor groups needing testing. Methods During a mass, multi-center HBV-screening study from September 2010-August 2011, 3929 participants were screened for hepatitis B surface antigen (HBsAg), anti-HBs and anti-Hepatitis B core antibodies (anti-HBcAb). Questions on HBV risk-factors and testing practices were asked to participants, while participants' eligibility for HBV-testing was asked to study medical professionals. Results 85 (2.2%) participants were HBsAg-positive, while 659 (16.8%) had either resolved HBV infection or isolated anti-HBcAb. When comparing practices, HBV-testing was more likely to occur in HBV-infected participants if Centers for Disease Control and Prevention (CDC) recommendations were used (Sensitivity = 100%, 95%CI: 95.8–100) than physicians' discretion (Sensitivity = 87.1%, 95%CI: 78.0–93.4) or previous HBV-test (Sensitivity = 36.5%, 95%CI: 26.3–47.6) (p<0.0001). Nevertheless, many non-infected individuals would still have been screened using CDC-recommendations (Specificity = 31.1%, 95%CI: 29.6–32.6). Using multivariable logistic regression, HBsAg-positive status was significantly associated with the following: males, originating from high HBV-endemic region, contact with HBV-infected individual, without national healthcare, and intravenous-drug user (IDU). Of these risk-factors, physician's discretion for testing HBV was not significantly associated with participants' geographical origin or IDU. Conclusions Missed opportunities of HBV-screening are largely due to underestimating country of origin as a risk-factor. Applying CDC-recommendations could improve HBV-screening, but with the disadvantage of many tests. Further development of

    Objective: To evaluate the transplantation of autologous bone marrow stem cells via hepatic artery in treating acute hepatic injury in experimental rabbit models and to clarify the synergistic effect of hepatocyte growth-promoting factor (pHGF) in stem cell transplantation therapy for liver injury. Methods Acute hepatic injury models were established in 15 experimental rabbits by daily subcutaneous injection of CCl 4 olive oil solution with the dose of 0.8 ml/kg for 4 days in succession. The experimental rabbits were randomly and equally divided into three groups: study group A (stem cell transplant, n = 5), study group B (stem cell transplant + pFHG, n = 5), and control group (n = 5). Bone marrow of 5 ml was drawn from the tibia in all rabbits of both study groups, from which bone marrow stem cells were isolated by using density gradient centrifugation, and 5 ml cellular suspension was prepared. Under fluoroscopic guidance, catheterization through the femoral artery was performed and the cellular suspension was infused into the liver via the hepatic artery. Only injection of saline was carried out in the rabbits of control group. For the rabbits in group B, pFHG (2.0 mg/kg) was administered intravenously every other day for 20 days. At 2, 4 and 8 weeks after stem cell transplantation, hepatic function was determined. Eight weeks after the transplantation all the rabbits were sacrificed and the liver specimens were collected and sent for pathological examination. Results After stem cell transplantation, the hepatic function was gradually improved.Eight weeks after the transplantation, the activity of AST, ALT and the content of ALB, TBIL were significantly lower than that before the procedure, while the content of GOLB was markedly increased in all rabbits. In addition, the difference in the above parameters between three groups was statistically significant (P < 0.05). Pathologically, the hepatocyte degeneration and the fiberous hyperplasia in the study groups

    The impact of chronic hepatitis B on the clinical outcome of acute hepatitis A remains controversial. The aim of present study was to evaluate the clinical characteristics of acute hepatitis A in cases with underlying chronic hepatitis B compared to cases of acute hepatitis A alone. Data on 758 patients with acute hepatitis A admitted at two university-affiliated hospitals were reviewed. Patients were classified into three groups: group A, patients with both acute hepatitis A and underlying chronic hepatitis B (n = 27); group B, patients infected by acute hepatitis A alone whose sexes and ages were matched with patients in group A (n  = 54); and group C, patients with acute hepatitis A alone (n = 731). None of the demographic features of group A were significantly different from those of group B or C, except for the proportion of males and body weight, which differed from group C. When comparing to group B, clinical symptoms were more frequent, and higher total bilirubin and lower albumin levels were observed in group A. When comparing to group C, the albumin levels were lower in group A. There were no differences in the duration of hospital stay, occurrence of acute kidney injury, acute liver failure, prolonged cholestasis, or relapsing hepatitis. This study revealed that clinical symptoms and laboratory findings were less favorable for patients with acute hepatitis A and chronic hepatitis B compared to those with acute hepatitis A alone. However, there were no differences in fatal outcomes or serious complications. Copyright © 2012 Wiley Periodicals, Inc.

    Objective: To investigate the relationship between the ultrasonographic changes of gallbladder wall and the hepatic inflammation grading as well as fibrostic staging using ultrasound examination in patients with chronic viral hepatitis, and to survey the diagnostic standard for viral related cholecystitis. Methods: Five hundreds and nineteen chronic viral hepatitis patients and 104 normal control subjects were enrolled in the study. Ultrasound guided liver biopsy was performed in all patients with chronic viral hepatitis, in which the hepatic fibrostic stages(S) were divided into SI (n=148), S2(n=170), S3-4(n 201 ); and hepatic inflammation grades (G) were divided into G1 (n=124 ), G2 (n=204), G3 (n=191). The ultrasound scan was performed within 7 days after liver biopsy. The relationship between ultrasonographic changes of gallbladder and the hepatic inflammation grades and fibrostic stages were analyzed using statistic soft ware SPSS 11.5 for windows. Results: The percentage of the thickened gallbladder wall were 55%, 87%, 96% in S1, S2, S3-4, respectively, and were 45%, 82%, 95% in G1, G2, G3-4, respectively. Significant difference was revealed between G1 and G2, as well as between G2 and G3-4, with P < 0.05. Conclusion: A significant, positive correlative relationship exists between the ultrasonographic changes of gall-bladder wall and the hepatic inflammation grading and fibrostic staging in patients with chronic viral hepatitis.

    Full Text Available Hepatic dysfunction in a patient with thyrotoxicosis may result from hyperthyroidism per se, as a side effect of antithyroid drugs, and causes unrelated to hyperthyroidism which sometimes causes diagnostic and therapeutic difficulties. A young female patient was admitted to our hospital with symptoms of thyrotoxicosis, diffuse goiter and ophthalmopathy along with cholestatic pattern of jaundice, and proximal muscle weakness. She was treated with propylthiouracil with gradual recovery. She was continuing her antithyroid medication with regular follow-up. The patient was readmitted a few months later with worsening thyrotoxicosis, proximal muscle weakness, fever, and a hepatocellular pattern of jaundice with sepsis. Propylthiouracil was stopped and lithium along with steroid coverage was given to control her thyrotoxicosis which was later changed to methimazole. Broad spectrum antibiotic therapy was also started but without any response. During her hospital stay, the patient also developed a flaccid paraplegia resembling Guillain-Barre syndrome. IV steroid was started for the neuropathy but meanwhile the patient succumbed to her illness. So in centers where facility for radioiodine therapy is not readily available, some definite well-tested protocols should be formulated to address such common but complicated clinical situations.

    To examine the outcomes of blunt hepatic trauma, and compare surgical and non-surgical treatment in patients admitted with hemodynamic stability and with no obvious indications of laparotomy. This is a retrospective study of cases admitted to a university teaching hospital between the years 2000 and 2010. Patients undergoing surgical treatment were divided into two groups: (a) all patients undergoing surgical treatment, and (b) patients with obvious need for surgery. In this period, 120 patients were admitted with blunt hepatic trauma. Sixty five patients (54.1%) were treated non-operatively and fifty five patients were operated upon. Patients treated non-operatively had better physiologic conditions on admission, demonstrated less severe injuries (except the grade of hepatic injury), received less blood components and had lower morbidity and mortality than the patients operated upon. Patients who underwent non-operative treatment had a lower need for blood transfusion but higher rates of complications and mortality than the patients operated upon. Patients who were operated upon, with no obvious indications for surgery, had higher rates of complication and mortality than patients not operated upon. A non-operative approach resulted in lower complications, a lower need for blood transfusions and lower mortality.

    Purpose: To compare the quantitative liver computed tomography perfusion (CTP) differences among eight hepatic segments. Materials and methods: This retrospective study was based on 72 acquired upper abdomen CTP scans for detecting suspected pancreas tumor. Patients with primary or metastatic liver tumor, any focal liver lesions except simple cyst (<3 cm in diameter), history of liver operation or splenectomy, evidence of liver cirrhosis or invasion of portal vein were excluded. The final analysis included 50 patients (M:F = 21:29, mean age = 43.2 years, 15–76 years). Arterial liver perfusion (ALP), portal-venous perfusion (PVP), total hepatic perfusion (THP = ALP + PVP), and hepatic perfusion index (HPI) of each hepatic segment were calculated and compared by means of one-way analysis of variance (ANOVA) and the Bonferonni correction method. Results: Compared to hepatic segments 5, 6, 7 and 8, segments 2 and 3 showed a tendency of higher ALPs, lower PVPs, and higher HPIs, most of which were statistically significant (p < 0.05). Hepatic segments 1 and 4 had higher mean values of ALP and HPI and lower mean values of PVP than segments 5, 6, 7 and 8 as well, although no significant differences were detected except for ALP and HPI for liver segments 1 and 7 (p = 0.001 and 0.035 respectively), and ALP for liver segments 1 and 5 (p = 0.039). Higher ALP and HPI were showed in hepatic segment 3 compared to segment 4 (p = 0.000 and 0.000 respectively). No significant differences were found for THP among eight segments. Conclusions: Intra-hepatic perfusion differences exist in normal hepatic parenchyma especially between lateral sector (segments 2 and 3) and right lobe (segments 5, 6, 7 and 8). This might have potential clinical significance in liver-perfusion-related protocol design and result analysis.

    A 38-year-old man presented for evaluation of severe pain in his lower limbs of 16 months' duration. Radiographs showed diffuse bony sclerosis involving the axial and appendicular skeleton with marked cortical thickening in the diaphyseal regions of the long bones. Iliac crest biopsy revealed abundant sclerotic bone. The patient was diagnosed with hepatitis C secondary to intravenous drug use 20 years earlier, and the bony findings and clinical symptoms attributed to hepatitis C-associated osteosclerosis (HCAO). Little is known about the natural history of this disease; however, we discuss the patient's clinical course over 15 years. (orig.)

    2012-03-01

    Full Text Available Acute cholecystitis is an inflammation of the gallbladder wall, usually caused by gallstones in the cystic duct, which causes attacks of severe pain. At least 95% of the population with acute inflammation of the gallbladder have gallstones. Acute viral hepatitis is the liver inflammation accompanied by nausea, faintness, vomiting, pain below the right rib arch, jaundice. The presence of acute cholecystitis intensifies the existing symptoms. The aim of the paper was to show the incidence of the gallbladder inflammation in patients with acute hepatitis A or B. This retrospective-prospective study involved 110 patients treated for viral hepatitis A or B and had severe abdominal pain during hospitalization. The selected sample involved more male examinees - 63 (62% compared to female ones - 47 (38%. The most frequent age of examinees was 30-50 years, 82 (83%, and cholecystitis during hepatitis was also most common in the age group 30-50 years, 28 (73% patients. Cholecystitis was more common in patients with acute hepatitis B - 21 (55% examinees than in patients with acute hepatitis A - 17 (45% examinees. Ultrasound examination, performed in 24 (63% examinees showed gallstones in inflamed gallbladder, while 14 (37% examinees had the inflammation of the gallbladder without gallstones. The most common cause of severe abdominal pain in patients with acute liver infection caused by HAV and HBV infection was the gallbladder, 38 (34.5% patients. Cholecystitis was more common in patients with acute hepatitis B, 21 (55% examinees, than in those with an acute hepatitis A, 17 (45% examinees.

    Objective: The use of liver as a reference tissue for semi-quantification of tumour FDG uptake may not be valid in hepatic steatosis (HS). Previous studies on the relation between liver FDG uptake and HS have been contradictory probably because they ignored blood glucose (BG). Because hepatocyte and blood FDG concentrations equalize, liver FDG uptake parallels BG, which must therefore be considered when studying hepatic FDG uptake. We therefore re-examined the relation between HS and liver uptake taking BG into account. Methods: This was a retrospective study of 304 patients undergoing routine PET/CT with imaging 60 min post-FDG. Average standard uptake value (SUV{sub ave}), maximum SUV (SUV{sub max}) and CT density (index of HS) were measured in a liver ROI. Blood pool SUV was based on the left ventricular cavity (SUV{sub LV}). Correlations were assessed using least squares fitting of continuous data. Patients were also divided into BG subgroups (<4, 4–5, 5–6, 6–8, 8–10 and 10+ mmol/l). Results: SUV{sub ave}, SUV{sub max} and SUV{sub LV} displayed similar relations with BG. SUV{sub max}/SUV{sub LV}, but not SUV{sub ave}/SUV{sub LV}, correlated significantly with BG. SUV{sub max}, but not SUV{sub ave}, correlated inversely with CT density before and after adjusting for BG. SUV{sub max}/SUV{sub ave} correlated more strongly with CT density than SUV{sub max}. CT density correlated inversely with SUV{sub max}/SUV{sub LV} but positively with SUV{sub ave}/SUV{sub LV}. Conclusions: Hepatic SUV is more influenced by BG than by HS. Its relation with BG renders it unsuitable as a reference tissue. Nevertheless, hepatic fat does correlate positively with liver SUV, although this is seen only with SUV{sub max} because SUV{sub ave} is ‘diluted’ by hepatic fat.

The vastmajority of viral hepatitis are caused by one of five hepatotropicviruses: hepatitis A virus (HAV), hepatitis B virus (HBV),hepatitis C virus (HCV), hepatitis D (delta) virus (HDV), andhepatitis E virus (HEV) (Table I) [1]. HBV, HCV, and HDValso cause chronic hepatitis, whereas HAV does not. HEVcauses acute hepatitis in normal hosts but can cause protractedand chronic he...

    Full Text Available Introduction Autoimmune hepatitis (AIH is a disease of unknown etiology. In pregnancy, it may have mild clinical course as well as can lead to liver failure, or exacerbation of clinical symptoms. In pregnant women the severity of symptoms is often observed between the second and third trimester, and in the puerperium. The disease is marked by enhanced activity of Th lymphocytes, which hepatocytes recognize as foreign antigens. This results in interleukin production activating B lymphocytes, and the production of specific antibodies attacking and destroying the hepatocytes. Case report A 35-year old patient, CII PII, 7 Hbd, with autoimmune hepatitis reported for a check-up. Her first pregnancy was 18 years ago, without history of underlying disease, carried to term without complications. The woman gave birth to a baby-son weighing 3,280g, 10 points Apgar. The delivery was spontaneous and uneventful. The patient got pregnant after an 18-year break. When she twice-tested positively for pregnancy, the treatment with azathioprine was switched to prednisolone. Over the pregnancy the patient was hospitalized 4 times, in 25, 29, 35, and 37 week of gestation due to a threat of preterm delivery, and pregnancy-related cholestasis associated with AIH. In 37 week of gestation, delivery was induced, and she gave birth to a healthy male, weighing 2,650 g, body height of 49 cm, 10 points Apgar scale. The liver function improved and stabilized after the delivery. Treatment with prednisolone has been continued, and the patient’s condition is still controlled. Pregnant patients with autoimmune hepatitis often experience exacerbation of the disease, especially in the third trimester, and in the postpartum period. This case shows that with proper care it is possible to continue and terminate pregnancy safely for the mother and her newly born baby.

    Background and objectives: The severity of liver disease among hepatitis C patients on hemodialysis is controversial. The aim of this study was to compare the clinical, biochemical, and liver histologic characteristics of hepatitis C virus (HCV) in hemodialysis patients and in those with normal renal function. Design, setting, participants, & measurements: A case-control study was carried out with 36 HCV patients on hemodialysis and 37 HCV patients with normal renal function matched for gender, age at infection, and estimated time of infection. Results: HCV patients on hemodialysis had lower levels of alanina aminotransferase and lower viral load. Hepatic fibrosis was significantly higher in the patients with normal renal function (73%) than in hemodialysis patients (47.2%, P < 0.025); the same was observed for inflammatory activity (control group 59.5% versus hemodialysis patients 27.7%, P = 0.003). In addition, the risk of tissue inflammation was four times lower in hemodialysis patients (odds ratio = 0.23, P < 0.004), and severe inflammatory activity on biopsy was the only independent risk factor for fibrosis (P < 0.001). Conclusions: The lower biochemical and inflammatory activities observed in hemodialysis patients suggest that hemodialysis and uremia may have a protective role against progression of the disease caused by HCV.

    of syphilis, hepatitis B surface antigen (HBsAg, antibodies to hepatitis B core (anti-HBc, hepatitis C (anti-HCV and HIV. RESULTS: The prevalence of syphilis was 2.4%, seroprevalence of anti-HCV was 0.5%, HBsAg 3.8% and anti-HBc 13.8%. No cases of HIV were observed. Higher prevalence of hepatitis B markers was associated with a lower level of education (p<0.05 and higher age (p<0.05. It was found that 38.5% of participant women never used condoms and 25.6% did not use any contraceptive method. CONCLUSION: It could be necessary to implement preventive programs to immunize sex workers against hepatitis B virus as well as education programs on condom use for their protection against sexually transmitted infections.

    Full Text Available Objective: to estimate the time course of changes in the levels of tumor necrosis factor-α (TNF-α, interleukin-4 (IL-4, IL-6, and the hepatic fibrosis indicators hyaluronic acid (HA and liver elasticity index during combined antiviral therapy (AVT with interferon alpha-2b and ribavirin in patients with chronic hepatitis C (CHC. Subjects and methods. Fifty patients with CHC were examined. Serum TNF-α, IL-6, IL-4, and HA were estimated using an enzyme immunoassay. The stage of hepatic fibrosis was determined by fibroelastography with the liver elastic index being measured; the time course of changes in the indicators was assessed in 20 patients at the end of AVT. A virological response was monitored at therapy completion and 6 months later. Results. The patients with CHC in the reactivation phase were found to have enhanced TNF-α, IL-6, and IL-4 activities in 84, 60, and 100 % of the cases, respectively (р < 0.001, р = 0.01, р < 0.001, respectively. The median serum concentration of HA in CHC was 1.8-fold higher than that in the control group (p = 0.03; the liver elastic index averaged 6.5 kPa. TNF-α and IL-6 levels correlated with viremia, transaminases, and hepatic fibrosis indicators. At combined AVT completion, the virological response rate was as high as 85 %, which was attended by a considerable reduction in cytolysis, HA concentrations, and liver density index to 5.4 kPa (3.6–6.8 kPa (p < 0.04, and in the activity of the examined cytokines. The sustained virological response rate was 80 %. Only IL-4 levels decreased and TNF-α and IL-6 concentration remained at the baseline level in patients unresponsive to AVT. Conclusion. It is expedient to monitor TNF-α, IL-4, IL-6, and HA to evaluate the severity of liver involvement in CHC and to predict the efficiency of AVT.

    The liver has a unique dual blood supply through the portal vein and the hepatic artery. There are several communications between these two vessels under various conditions such as in hepatic tumors, trauma and liver cirrhosis, vascular compromise, among others. When vascular compromise occurs, this dual blood supply system can cause changes in the volume of blood flow in individual vessels or even in the direction of blood flow. With rapid image acquisition and increased resolution available in multislice CT and MR imaging, hepatic perfusion disorders are now more frequently encountered than in the past. Familiarity with imaging findings of these perfusion disorders will be helpful in characterizing focal hepatic lesions and will also help to avoid false positive diagnoses

    Hepatitis is an inflammatory disease of the liver. In sever cases, it may lead to permanent liver damage including liver cirrhosis or hepato-cellular carcinoma and may ultimately lead to death. Health-care workers (HCWs), due to their regular contact with patients are at a high-risk of acquiring this disease. The aim of this study was to assess the knowledge and attitude toward hepatitis B and C infection among the health-care interns and correlate the level of awareness to the attitude they behold toward the disease. A closed ended questionnaire consisting of questions to evaluate the knowledge regarding hepatitis B and C infection and attitude of the (HCWs/interns) was duly filled by 255 participants including, 100 dental, 100 medical, and 55 nursing interns. Statistical analysis was carried out using the Chi-square test, ANOVA test, post-hoc test and Pearson's correlation. Although most of the interns were aware of the existence of hepatitis B and C infection, the level of awareness regarding the modes of transmission and vaccination was found to be dissatisfactory. Awareness level regarding the infection among nursing interns was statistically significantly lower than the dental and medical interns. A direct positive correlation as found between awareness score and behavior score, which reveals that interns with better awareness level had better attitudes toward the infection and prevention of its transmission. There is an urgent need to increase the level and quality of training among HCWs to prevent the spread of hepatitis B virus and hepatitis C virus.

    Autoimmune hepatitis (AIH) is a severe life-threatening hepatopathy of unknown etiology, affecting both pediatric and adult populations, and characterised by inflammatory liver histology, circulating non-organ-specific autoantibodies, and hypergammaglobulinaemia. AIH is a very heterogeneous disease with a variety of clinical presentations, ranging from asymptomatic liver test abnormalities to acute severe hepatitis or even acute liver failure. It responds very well to immunosuppressive treatment with prednisolone with or without azathioprine. Patients who are intolerant or fail to respond to standard therapy are candidates for alternative immunosuppressive regimens, the combination of steroids with mycophenolate mofetil or calcineurin inhibitors being the most frequently reported. The pathogenesis of AIH remains not completely understood, although there is evidence that genetic predisposition, molecular mimicry and defective immunoregulatory mechanisms contribute to the autoimmune liver damage. A literature search was conducted using the key-words 'autoimmune hepatitis', 'immunogenetics', 'regulatory T-cells' and 'immunosuppression'. The aim of this review is to discuss recent breakthroughs in the understanding AIH pathogenesis, diagnosis and treatment. Expert commentary: Progress in the understanding of AIH pathogenesis is likely to contribute to the development of novel therapeutic strategies, such as the adoptive transfer of autologous expanded antigen-specific regulatory T-cells.

    Immunosuppressive CD11b+Gr-1+ myeloid-derived suppressor cells (MDSC) accumulate in the livers of tumor-bearing mice. We studied hepatic MDSC in two murine models of immune mediated hepatitis. Unexpectedly, treatment of tumor bearing mice with Concanavalin A or α-Galactosylceramide resulted in increased ALT and AST serum levels in comparison to tumor free mice. Adoptive transfer of hepatic MDSC into naïve mice exacerbated Concanavalin A induced liver damage. Hepatic CD11b+Gr-1+ cells revealed a polarized pro-inflammatory gene signature after Concanavalin A treatment. An interferon gamma- dependent up-regulation of CD40 on hepatic CD11b+Gr-1+ cells along with an up-regulation of CD80, CD86, and CD1d after Concanavalin A treatment was observed. Concanavalin A treatment resulted in a loss of suppressor function by tumor-induced CD11b+Gr-1+ MDSC as well as enhanced reactive oxygen species-mediated hepatotoxicity. CD40 knockdown in hepatic MDSC led to increased arginase activity upon Concanavalin A treatment and lower ALT/AST serum levels. Finally, blockade of arginase activity in Cd40−/− tumor-induced myeloid cells resulted in exacerbation of hepatitis and increased reactive oxygen species production in vivo. Our findings indicate that in a setting of acute hepatitis, tumor-induced hepatic MDSC act as pro-inflammatory immune effector cells capable of killing hepatocytes in a CD40-dependent manner.

    The past several years have seen significant advances in diagnostic and interventional radiology. These advances have been particularly rewarding for the study of liver disease. Improved imaging and therapeutic procedures in oncology have generated changes in treatment protocols and in evaluating the results of therapy for hepatic malignancies. The enriched understanding of the anatomic and hemodynamic aspects of the portal system has greatly benefited patients with portal hypertension. Now physicians are confidently more aggressive in the therapeutic approach to the variceal bleeder, and they have modified their approach to the preservation of portal flow following shunt. All of the diagnostic modalities used to evaluate the liver are represented in this book. In its structure and organization this volume goes beyond a historical overview of imaging to present greater insight into the current state of the art, as well as possible future developments. Each chapter is designed to elucidate the advantages and weaknesses of the various diagnostic modalities

    Toxic hepatitis is observed with high doses of Venlafaxine. But toxic hepatitis has not been yet reported at lower doses of Venlafaxine such as 37.5 mg per day. In this case report, a case of Venlafaxine associated toxic hepatitis with lower doses in patient with history of chronic hepatitis is presented. We suggest that liver function should be regularly monitored in patients with history of chronic hepatitis receiving Venlafaxine even at lower doses and even when their liver enzymes are normal.

    Full Text Available Abstract Background Hepatic encephalopathy has a negative impact on health-related quality of life (QoL in liver cirrhosis. There are scarce and conflicting data on whether type or etiology of liver cirrhosis could be related to hepatic encephalopathy in patients with cirrhosis. We aimed to determine the impact of cirrhosis etiology on hepatic encephalopathy and whether hepatic encephalopathy affects health-related QoL among patients with cirrhosis of different etiologies. Methods A total of 156 cirrhotic patients were prospectively evaluated for the presence of hepatic encephalopathy according to the West-Haven criteria as well as by means of two psychometric tests. Patients with cryptogenic cirrhosis or cirrhosis due to mixed hepatocellular/cholestatic etiologies were excluded. Fasting plasma glucose levels were also measured. QoL was evaluated by means of a validated questionnaire (SF-36. Results Diabetes mellitus was more common in patients with hepatocellular cirrhosis compared to those with cholestatic cirrhosis but the two groups did not differ in cirrhosis severity or the prevalence of hepatic encephalopathy (p > 0.05. The groups of patients with cirrhosis due to alcohol, hepatitis C, or cholestatic liver disease did not differ in severity of liver cirrhosis or the prevalence of hepatic encephalopathy (p > 0.05. Patients with cirrhosis of different etiologies did not differ in any SF-36 domain (p > 0.05. In multivariate analysis, performance at neuropsychological testing was independently related only to age, diabetes mellitus, and the Child-Pugh score whereas the SF-36 physical component summary only to the Child-Pugh score and hepatic encephalopathy. Conclusion Cirrhosis etiology does not seem to be related to hepatic encephalopathy or health-related QoL. Cognitive impairment is associated mainly with age, liver disease severity and diabetes mellitus.

  19. Links between human LINE-1 retrotransposons and hepatitis virus-related hepatocellular carcinoma

    2016-05-01

    Hepatocellular carcinoma (HCC) accounts for approximately 80% of liver cancers, the third most frequent cause of cancer mortality. The most prevalent risk factors for HCC are infections by hepatitis B or hepatitis C virus. Findings suggest that hepatitis virus-related HCC might be a cancer in which LINE-1 retrotransposons, often termed L1, activity plays a potential role. Firstly, hepatitis viruses can suppress host defense factors that also control L1 mobilization. Secondly, many recent studies also have indicated that hypomethylation of L1 affects the prognosis of HCC patients. Thirdly, endogenous L1 retrotransposition was demonstrated to activate oncogenic pathways in HCC. Fourthly, several L1 chimeric transcripts with host or viral genes are found in hepatitis virus-related HCC. Such lines of evidence suggest a linkage between L1 retrotransposons and hepatitis virus-related HCC. Here, I briefly summarize current understandings of the association between hepatitis virus-related HCC and L1. Then, I discuss potential mechanisms of how hepatitis viruses drive the development of HCC via L1 retrotransposons. An increased understanding of the contribution of L1 to hepatitis virus-related HCC may provide unique insights related to the development of novel therapeutics for this disease.

    2010-03-01

    Hepatitis E virus (HEV), the causative agent of hepatitis E, belongs to the family Hepeviridae. At least four major genotypes of HEV have been recognized: genotypes 1 and 2 are restricted to humans and associated with epidemics in developing countries, whereas genotypes 3 and 4 are zoonotic and infect humans and several other animals in both developing and industrialized countries. Besides humans, strains of HEV have been genetically identified from swine, chickens, sika deer, mongeese, and rabbits. The genome of HEV consists of three open reading frames (ORFs): ORF1 codes for nonstructural proteins, ORF2 codes for capsid protein, and ORF3 codes for a small multifunctional protein. The ORF2 and ORF3 proteins are translated from a single bicistronic mRNA and overlap each other but neither overlaps ORF1. The recent determination of the 3D crystal structure of the HEV capsid protein should facilitate the development of vaccines and antivirals. The identification and characterization of animal strains of HEV from pigs and chickens and the demonstrated ability of cross-species infection by swine HEV raise public health concerns for zoonosis. Accumulating evidence indicated that hepatitis E is a zoonotic disease and pigs and more likely other animal species are reservoirs for HEV. This article provides an overview of the recent advances in hepatitis E and its causative agent, including nomenclature and genomic organization, gene expression and functions, 3D structure of the virions, changing perspectives on higher mortality during pregnancy and chronic hepatitis E, animal reservoirs, zoonotic risk, food safety, and novel animal models.

    Nonoperative management (NOM) of hepatic injuries caused by blunt trauma in hemodynamically stable patients is widely accepted, but the feasibility of NOM for severe hepatic injuries has not been fully evaluated. Among all patients with blunt severe hepatic injury (type IIIb) admitted to Saiseikai Kanagawa-ken Hospital and Keio University Hospital from 1988 to 2004, those who had been hemodynamically stable after fluid resuscitation at the emergency department were initially managed nonoperatively. We reviewed demographic, physiological, and laboratory data; computed tomography (CT) findings; 80-day cumulative laparotomy rate; and complications. The anatomical severity of the hepatic injuries was evaluated based on the CT findings, such as hepatic vein injuries and area lacerated according to the Couinaud liver segment. In patients who underwent surgery after admission, the surgical indications and operative findings were reviewed. Overall, 34 consecutive patients were enrolled in this study. Five patients underwent surgery, and all of their surgical indications were attributable to liver-related complications after injury. The indication for surgery was hemodynamic instability in 3 patients with hepatic vein injures in the early phase (<15 hours after estrogen receptor (ER) arrival) and intra-abdominal septic complications in 2 patients in the late phase (hospital days 14 and 64). The cumulative 80-day laparotomy rate in the early phase was significantly higher (p<0.0001) in the patients suspected of having hepatic vein injury, and in the late phase it was higher (p=0.002) in those with injuries in 4 or more segments of hepatic injuries. For the successful NOM of blunt hepatic injury type IIIb in patients who are hemodynamically stable after fluid resuscitation, a strong suspicion of concurrent hepatic vein injury is critical in the early phase, and laceration in 4 or more segments should be noted in the late phase.

    {sup 99m}Tc-diethylenetriamine-pentaacetic acid-galactosyl human serum albumin({sup 99m}Tc-GSA) scintigraphy has been reported as a useful study of hepatic functional reserve recently. We have performed {sup 99m}Tc-N-pyridoxyl-5-methyl-tryptophan({sup 99m}Tc-PMT) and {sup 99m}Tc-GSA preoperatively for evaluation of hepatic functional reserve and compared the usefulness of those scintigraphy study. Twenty-four patients who were the candidates of hepatic resection underwent {sup 99m}Tc-PMT scintigraphy preoperatively. Hepatic blood flow coefficient (K value), the amount of hepatic blood flow (HBF), and the ratio of portal blood flow (PVR) were computed. {sup 99m}Tc-GSA scintigraphy was also performed within two weeks of the {sup 99m}Tc-PMT scintigraphy, and the ratio of disappearance (HH{sub 15}) and the hepatic uptake ratio (LHL{sub 15}) were computed. The relationship between K value, HBF, PVR, HH{sub 15} and LHL{sub 15} was analyzed. Their correlation with other liver function tests was also examined. K value and HBF did not show statistically significant correlations with HH{sub 15} and LHL{sub 15}, PVR correlated statistically significantly HH{sub 15} and LHL{sub 15}. K value correlated with the preoperative values of cholinesterase, Fischer ratio, {gamma}-globulin, ICGR{sub 15}, albumin, and platelet count. There was a statistically significant correlation between LHL{sub 15} and the value of cholinesterase, {gamma}-globulin, platelet count, and Fischer ratio. When the liver resection of subsegmentectomy or more was indicated in 10 patients, nine patients had LHL{sub 15} value less than 0.9 which delineated possibility of poor prognosis. However, judging from K value and HBF, liver resection was considered feasible and it was all successfully performed, resulting in good prognosis. From this study, it is suspected that {sup 99m}Tc-GSA scintigraphy reflect the severity of liver fibrosis and the amount of portal blood flows, and {sup 99m}Tc-PMT scintigraphy

    Objective: To study the temperature difference, tolerated high temperature, pathological changes between normal and blocked hepatic artery in radiofrequency hyperthermia for pig liver. Methods: Mature pig was used with iodine blocked right hepatic artery. Heat of the whole liver was given for 1 hour by SR-1000 radiofrequency hyperthermia with four thermocouple probes to measure the temperature of the right hepatic artery, right and left normal liver and rectum. Results: Temperature of blocked right liver increased by 10.2 degree C from 39.1 degree C to 49.3 degree C as compared with the left liver of which the temperature rose by 6.8 degree C from 39.7 degree C to 46.5 degree C but the temperature of right hepatic artery and rectum rose only by 3.3 degree C, 3.2 degree C respectively. After sacrificing the pig one week later, on lobe exploration, severe necrosis was observed in the right lobe but the left lobe was normal with a clear demarcation between the two lobes. Conclusions: Hepatic arterial iodine embolization potentiates radiofrequency hyperthermia in the liver. Liver with blocked artery showed conspicuous necrosis but liver with normal un-blocked artery was able to tolerate 46.5 degree C. This provides some evidence for the combination of regional hyperthermia and hepatic artery block in the treatment of advanced liver cancer

  5. Rituximab-Based Treatment, HCV Replication, and Hepatic Flares

    Directory of Open Access Journals (Sweden)

    2012-01-01

    Full Text Available Rituximab, a chimeric mouse-human monoclonal antibody directed to the CD20 antigen expressed on pre-B lymphocytes and mature lymphocytes, causes a profound B-cell depletion. Due to its peculiar characteristics, this drug has been used to treat oncohaematological diseases, B cell-related autoimmune diseases, rheumatoid arthritis, and, more recently, HCV-associated mixed cryoglobulinaemic vasculitis. Rituximab-based treatment, however, may induce an increased replication of several viruses such as hepatitis B virus, cytomegalovirus, varicella-zoster virus, echovirus, and parvovirus B19. Recent data suggest that rituximab-based chemotherapy induces an increase in HCV expression in hepatic cells, which may become a target for a cell-mediated immune reaction after the withdrawal of treatment and the restoration of the immune control. Only a few small studies have investigated the occurrence of HCV reactivation and an associated hepatic flare in patients with oncohaematological diseases receiving R-CHOP (rituximab, cyclophosphamide, doxorubicin, vincristine, and prednisone. These studies suggest that the hepatic flares are frequently asymptomatic, but life-threatening liver failure occurs in nearly 10% of cases.

    Rituximab, a chimeric mouse-human monoclonal antibody directed to the CD20 antigen expressed on pre-B lymphocytes and mature lymphocytes, causes a profound B-cell depletion. Due to its peculiar characteristics, this drug has been used to treat oncohaematological diseases, B cell-related autoimmune diseases, rheumatoid arthritis, and, more recently, HCV-associated mixed cryoglobulinaemic vasculitis. Rituximab-based treatment, however, may induce an increased replication of several viruses such as hepatitis B virus, cytomegalovirus, varicella-zoster virus, echovirus, and parvovirus B19. Recent data suggest that rituximab-based chemotherapy induces an increase in HCV expression in hepatic cells, which may become a target for a cell-mediated immune reaction after the withdrawal of treatment and the restoration of the immune control. Only a few small studies have investigated the occurrence of HCV reactivation and an associated hepatic flare in patients with oncohaematological diseases receiving R-CHOP (rituximab, cyclophosphamide, doxorubicin, vincristine, and prednisone).

    Full Text Available Objective: There are very few data about the epidemiology of hepatitis B virus (HBV, hepatitis C virus (HCV and HIV infections in drug addicts in Turkey, whereas several countries have a developed surveillance systems to monitor the spread of HBV, HCV and HIV infections in drug users. In this study, HBV, HCV and HIV prevalence in cannabis and opioid addicts were investigated. Materials and Methods: Hepatitis B surface antigen (HBsAg, anti-HBs, anti-HCV and anti-HIV tests were analyzed by enzyme-linked immunosorbent assay. The cannabis and opioid metabolites in urine samples of drug addicts were analyzed by cloned enzyme donor immunoassay. Results: This retrospective study was conducted on 276 individuals with a mean age of 28.89±10.49 years. HBsAg, anti-HBs and anti-HCV prevalence in drug addicts was found to be 4%, 52.3% and 7.9%, respectively. In all the drug addicts, anti-HIV test was negative. Whereas the rate of HBsAg among cannabis users (8.8% was higher than opioid (4.1% and both cannabis and opioid users (1.4%, the difference was not statistically significant. Although anti-HCV positivity among cannabis users was not detected, 6.4% of opioid users and 15.9% of both cannabis and opioid users were anti-HCV positive (p=0.009. Conclusion: This study showed that HCV infection among especially opioid users and both cannabis and opioid users was a problem. Understanding of local status in HBV, HCV and HIV infections is crucial for developing prevention and geographical strategies for these infections.

    During the past ten years, several new hepatitis E viruses (HEVs) have been identified in various animal species. In parallel, the number of reports of autochthonous hepatitis E in Western countries has increased as well, raising the question of what role these possible animal reservoirs play in human infections. The aim of this review is to present the recent discoveries of animal HEVs and their classification within the Hepeviridae family, their zoonotic and species barrier crossing potential, and possible use as models to study hepatitis E pathogenesis. Lastly, this review describes the transmission pathways identified from animal sources.

    Objective: To determine fetomaternal outcome in pregnant women with acute hepatitis E in terms of pregnancy outcome and perinatal mortality. Study Design: Case series. Place and Duration of Study: Department of Obstetrics and Gynecology, Sir Ganga Ram Hospital, Lahore, from July 2012 to March 2013. Methodology: Serum samples of 38 patients who presented with jaundice in pregnancy were collected to detect hepatitis E IgM antibodies. Demographics, pregnancy outcome and perinatal mortality was noted in hepatitis E positive cases with cause of complications. Cases with jaundice due solely to any other cause were excluded. Results: Twenty five patients had acute hepatitis E with coexistent acute hepatitis A in 1(4%) patient. Their mean age was 25 years and mean gravidity was 2. Among them, 10 (40%) patients were primigravida followed by gravida two in 7 (28%) cases. Twenty four (96%) patients presented in third trimester of pregnancy and in 1 (4%) pregnancy ended in second trimester missed miscarriage. The mean gestational age was 32 weeks. Twenty one (84%) babies were born alive, among them 18 (86%) were preterm. Perinatal mortality was 26%; contributed by intrauterine deaths and early neonatal deaths in 3 (14%) cases each. Total maternal deaths were 5 (20%), 4 (80%) in postpartum period and 1 (20%) in antepartum period due to fulminant hepatic failure in all cases. Conclusion: Prematurity in newborns and fulminant hepatic failure in mothers are major cause of poor fetomaternal outcome in acute hepatitis E in pregnancy. (author)

    The hepatic bridge forms a tunnel of liver parenchyma that may obscure peritoneal metastases associated with the round ligament. Visualization and then resection of nodules associated with this structure is necessary. The incidence of a hepatic bridge and the extent that it covered the round ligament was determined in consecutive patients. Extent of coverage of the round ligament by the hepatic bridge was determined: Class 1 indicates up to one-third of the round ligament obscured, Class 2 up to two-thirds and Class 3 more than two-thirds. In 102 patients in whom the round ligament of the liver could be completely visualized, 50 had a hepatic bridge. Class 1 was 22 (44%) of the bridges, Class 2 was 16 (32%) and Class 3 was 12 (24%). A hepatic bridge was more frequently present in 28 of 45 male patients (62%) vs. 22 of 57 female patients (38%). Approximately one-half of our patients having cytoreductive surgery for peritoneal metastases were observed to have a hepatic bridge. Up to 56% of these patients have Class 2 or 3 hepatic bridge and may require division of the hepatic bridge to completely visualize the contents of the tunnel created by this structure.

    To evaluate the MR appearance of the accessory hepatic veins. The study included 87 consecutive patients for whom abdominal MR images were obtained. The subjects who had liver lesion or hepatic vascular abnormalities were excluded. Couinaud classified accessory hepatic veins into inferior and middle right hepatic veins. Our major interests were evaluation of the incidence, morphology, and location of the accessory hepatic vein. Inferior right hepatic vein was demonstrated in 43 out of 87 patients (49%). The morphology was linear in 35 patients (80.5%), and V-shaped in 8 patients (19.5%). In 40 patients (93%), the inferior right hepatic vein was located in the posteroinferior aspect of the right lobe. Middle right hepatic vein was demonstrated in 7 out of 87 patients (8%). All were single linear in morphology, combined with the inferior right hepatic vein, and located between the right hepatic vein and inferior right hepatic vein. The accessory hepatic vein was demonstrated in 49% among the Korean adult population, and was located in posteroinferior portion of the liver, in 93%

    Objectives We examined whether arginase inhibition influences hepatic metabolic pathways and whole body adiposity in diet-induced obesity. Methods and Results After obesity induction by a high fat diet (HFD), mice were fed either the HFD or the HFD with an arginase inhibitor, Nω-hydroxy-nor-L-arginine (nor-NOHA). Nor-NOHA significantly prevented HFD-induced increases in body, liver, and visceral fat tissue weight, and ameliorated abnormal lipid profiles. Furthermore, nor-NOHA treatment reduced lipid accumulation in oleic acid-induced hepatic steatosis in vitro. Arginase inhibition increased hepatic nitric oxide (NO) in HFD-fed mice and HepG2 cells, and reversed the elevated mRNA expression of hepatic genes in lipid metabolism. Expression of phosphorylated 5′ AMPK-activated protein kinase α was increased by arginase inhibition in the mouse livers and HepG2 cells. Conclusions Arginase inhibition ameliorated obesity-induced hepatic lipid abnormalities and whole body adiposity, possibly as a result of increased hepatic NO production and subsequent activation of metabolic pathways involved in hepatic triglyceride metabolism and mitochondrial function.

    INTRODUCTION: Understanding the spectrum and frequencies of Epstein-Barr virus (EBV) complications and markers of illness severity in immunocompetent patients with primary EBV infection will inform management of patients with EBV-related illnesses. OBJECTIVES: To determine the clinical and laboratory correlates of illness severity among infants, children and youth with infectious mononucleosis (IM). METHODS: Study subjects with confirmed IM were prospectively enrolled. Illness severity was assessed at baseline and at six weeks using a scoring tool. Peripheral blood viral loads served as a measure of viral burden. RESULTS: Among 32 children and young adults with IM, the median age was 16 years (range two to 24 years). The predominant clinical findings were lymphadenopathy (23 of 32 [72%]), pharyngitis (16 of 32 [50%]), fever (nine of 32 [28%]) and splenomegaly (six of 32 [19%]). With respect to symptoms or signs that persisted to at least six weeks after illness onset, the predominant complaint was lymphadenopathy in 35% of subjects available for reassessment. Deranged liver function tests were present at presentation in up to 44% of subjects. Patients with the highest viral loads at presentation had significantly higher illness severity scores associated with fatigue (P=0.02). Other than the scores associated with fatigue, viral load values were not significantly correlated with the illness severity scores at baseline and at six weeks. CONCLUSION: In IM, viral loads are not necessarily correlated with illness severity, with the exception of fatigue. EBV-related hepatitis is common in IM, confirming the status of this virus as a relatively common cause of transient hepatitis in children and youth. This entity is not necessarily a marker of disease severity. PMID:25371691

    To evaluate changes of serum leptin levels in patients with viral hepatitis C(HCV), serum leptin levels were determined by RIA in 65 patients with viral chronic hepatitis C and in 80 control subjects ,liver function (ALT, AST) , glucose (Glu) , and total cholesterol (TC) were evaluated too. Campared with controls, the levels of serum leptin were significantly increased in patients with HCV (P 0.05). The levels of serum leptin increased in patients with HCV, which correlates positively with the severity of liver inflammation, so that leptin can be regarded as an index which reflects the severity of liver inflammation.

  18. Liver macrophages: friend or foe during hepatitis B infection?

    2018-05-17

    The Hepatitis B virus chronically infects the liver of 250 million people worldwide. Over the past decades, major advances have been made in the understanding of Hepatitis B virus life cycle in hepatocytes. Beside these parenchymal cells, the liver also contains resident and infiltrating myeloid cells involved in immune responses to pathogens and much less is known about their interplay with Hepatitis B virus. In this review, we summarized and discussed the current knowledge of the role of liver macrophages (including Kupffer cells and liver monocyte-derived macrophages), in HBV infection. While it is still unclear if liver macrophages play a role in the establishment and persistence of HBV infection, several studies disclosed data suggesting that HBV would favour liver macrophage anti-inflammatory phenotypes and thereby increase liver tolerance. In addition, alternatively activated liver macrophages might also play in the long term a key role in hepatitis B associated pathogenesis, especially through the activation of hepatic stellate cells. Therapies aiming at a transient activation of pro-inflammatory liver macrophages should therefore be considered for the treatment of chronic HBV infection. This article is protected by copyright.

    A region of interest angiohepatogram was obtained with intravenous injection of 10mCi of sup(99m)Tc-Sn-colloid and a data processing system. Furthermore, the ratio of hepatic arterial blood flow volume to total hepatic blood flow volume was calculated according to Ueda's method, and the correlation of this calculated ratio and the degree of extrahepatic distribution of sup(99m)Tc-Sn-colloid (spleen to liver, and bone marrow to liver activity ratio) was examined. Most cases of liver cirrhosis and Banti's syndrome showed the increased hepatic arterial blood flow ratio (liver cirrhosis: 43.5+-9.5%, Banti's syndrome 48.8+-4.9%) in contrast with 18.1+-4.6% in normal cases, and its ratio showed much higher values in the presence of portal hypertension manifestations (esophageal varix and ascites). The hepatic arterial blood flow ratio showed increased values in the case of markedly increased extrahepatic activity, e.g. liver cirrhosis, and the correlation of the ratio and extrahepatic activity degree of sup(99m)Tc-Sn-colloid was significant statistically. From these results, a region of interest angiohepatogram was supposed to be useful for the prediction of the hemodynamic change, as well as, the improvement of diagnostic accuracy with radioisotope in diffuse hepatic disease, especially liver cirrhosis. Moreover, the hemodynamic change of liver, especially the reduction of the effective hepatic blood flow volume via the portal vein was considered to be closely concerned in the mechanism of increased extrahepatic activity of RI colloid in diffuse hepatic disease.

    BACKGROUND:: Hepatitis delta virus (HDV) infection results in the most aggressive form of chronic viral hepatitis. There is scarce information about the prevalence, epidemiology, virological profile and natural historyof hepatitis delta in HIV patients. METHODS:: From 16,597 HIV patients enrolled......-RNA was quantified using a real-time PCR method. RESULTS:: A total of 61/422 HBsAg+ carriers were anti-HDV+ (prevalence: 14.5%). Hepatitis delta predominated in intravenous drug users and for this reason in South and/or East Europe. Serum HDV-RNA was detectable in 87% of tested anti-HDV+ patients, with a median...... titer of 1.76x10¿copies/ml. Overall, delta hepatitis patients showed lower serum HBV-DNA than the rest of HBsAg+ carriers, although the inhibitory effect of HDV on HBV replication was not recognized in HBV genotype D patients.Whereas HDV was not associated with progression to AIDS, it significantly...

    This study aimed to identify acute self-limited hepatitis B (ASL-HB) among patients presenting with hepatitis B virus (HBV)-related acute hepatitis. Data were available for 220 patients diagnosed with HBV-related acute hepatitis, of whom 164 had acute hepatitis B (AHB). Of these, 160 were confirmed as ASL-HB: three (1.9%) evolved to chronic hepatitis B and one (0.6%) developed fulminant hepatitis and died. Comparisons were also made between AHB and acute infections with hepatitis A (HA) and hepatitis E (HE) viruses. During the study period, the number of patients with AHB exceeded the sum of those with acute HA and acute HE infections. There was no distinct seasonal peak for AHB infection, whereas both acute HA and acute HE infections occurred more frequently in the spring. Clinical symptoms and physical signs were similar for all three types of hepatitis, but significant differences were seen in some biochemical parameters. In conclusion, this study suggests that symptomatic AHB is not rare in China but it seldom evolves to chronic hepatitis B.

    Objective: To investigate the liver function damage and serum hepatic fibrosis markers levels changes in patients suffering from trichloroethylene induced drugrash-like dermatitis. Methods: Serum hyaluronic acid (HA), laminin (LN), procollagen type III (PC III), type IV collagen ( IV C) levels (with RIA), mono-amine oxidase (MAO) activity (with chemo-colorimetry) and liver function tests (including ALT, AGT, total protein, albumin, total bile acid, with automated biochemical analysis system) were determined in 30 controls and 30 patients with trichloroethylene induced drugrash-like dermatitis. Results: Severe liver function damage was demonstrated in all the patients. The serum hepatic fibrosis markers levels were significantly increased (vs controls, P<0.01) and correlated well with the degree of hepatic damage. Conclusion: Liver damage occurred early in patients with trichloroethylene induced dermatitis, accompanied with laboratory evidence of hepatic fibrosis. (authors)

    Alcoholic hepatitis is a clinical syndrome characterized by jaundice and liver impairment that occurs in patients with a history of heavy and prolonged alcohol use. The short-term mortality among patients with severe disease exceeds 30%. Prednisolone and pentoxifylline are both recommended for the treatment of severe alcoholic hepatitis, but uncertainty about their benefit persists. We conducted a multicenter, double-blind, randomized trial with a 2-by-2 factorial design to evaluate the effect of treatment with prednisolone or pentoxifylline. The primary end point was mortality at 28 days. Secondary end points included death or liver transplantation at 90 days and at 1 year. Patients with a clinical diagnosis of alcoholic hepatitis and severe disease were randomly assigned to one of four groups: a group that received a pentoxifylline-matched placebo and a prednisolone-matched placebo, a group that received prednisolone and a pentoxifylline-matched placebo, a group that received pentoxifylline and a prednisolone-matched placebo, or a group that received both prednisolone and pentoxifylline. A total of 1103 patients underwent randomization, and data from 1053 were available for the primary end-point analysis. Mortality at 28 days was 17% (45 of 269 patients) in the placebo-placebo group, 14% (38 of 266 patients) in the prednisolone-placebo group, 19% (50 of 258 patients) in the pentoxifylline-placebo group, and 13% (35 of 260 patients) in the prednisolone-pentoxifylline group. The odds ratio for 28-day mortality with pentoxifylline was 1.07 (95% confidence interval [CI], 0.77 to 1.49; P=0.69), and that with prednisolone was 0.72 (95% CI, 0.52 to 1.01; P=0.06). At 90 days and at 1 year, there were no significant between-group differences. Serious infections occurred in 13% of the patients treated with prednisolone versus 7% of those who did not receive prednisolone (P=0.002). Pentoxifylline did not improve survival in patients with alcoholic hepatitis. Prednisolone

    Brain MRI was carried out in patients with chronic liver diseases. No abnormal findings were recognized in patients with chronic viral hepatitis, while 59.2% of cirrhotics showed a symmetrically strong signal in basal ganglia on T1 weighted image in MRI. This finding significantly related with lowered Fischer's ratio of serum amino acid, increased levels of serum phenylalanine, tyrosine and hyaluronic acid, prolonged prothrombin time and decreased platelet counts in the peripheral blood. Overt hepatic encephalopathy was observed in 6 of 34 patients with the strong signal in MRI during follow-up period, while none of patients without that finding developed hepatic encephalopathy. These results have indicated that the strong signal in basal ganglia on MRI appears in cirrhotic patients with severe liver dysfunction, and it is an useful index in the early diagnosis of latent hepatic encephalopathy. An improvement of this MRI finding was not observed by long-term oral administration of branched-chain amino acid. (author)

    2016-01-01

    BACKGROUND & AIMS Innate immune activation has been postulated as a central mechanism for disease progression from hepatic steatosis to steatohepatitis in obesity-related fatty liver disease. Arginase 2 competes with inducible nitric oxide synthase (iNOS) for its substrate and the balance between these two enzymes plays a crucial role in regulating immune responses and macrophage activation. Our aim was to test the hypothesis that arginase 2 deficiency in mice favors progression from isolated hepatic steatosis, induced by high fat feeding to steatohepatitis. METHODS Arginase 2-knockout (Arg2−/−) mice were studied for changes in liver histology and metabolic phenotype at baseline and after a short term course (7 week) feeding with a high fat (HFAT) diet. In additional experiments, Arg2−/− mice received tail vein injections of liposome-encapsulated clodronate (CLOD) over a three-week period to selectively deplete liver macrophages. RESULTS Unexpectedly, Arg2−/− mice showed profound changes in their livers at baseline characterized by significant steatosis as demonstrated with histological and biochemical analysis. These changes were independent of systemic metabolic parameters and associated with marked increase mRNA levels of genes involved in hepatic de novo lipogenesis. Liver injury and inflammation were present with elevated serum ALT, marked infiltration of F4/80 positive cells, and increased mRNA levels of inflammatory genes. HFAT feeding exacerbated these changes. Macrophage depletion after CLOD injection significantly attenuated lipid deposition and normalized lipogenic mRNA profile of livers from Arg2−/− mice. CONCLUSIONS This study identifies arginase 2 as novel link between innate immune responses, hepatic lipid deposition, and liver injury. PMID:25234945

    1990-01-01

    A 23 year old man presented with hepatic veno-occlusive disease and severe portal hypertension and subsequently died from liver failure. Light microscopy and hepatic angiography showed occlusion of sublobular veins and small venous radicles of the liver, associated with widespread haemorrhagic necrosis of hepatocytes. The patient had been on a predominantly vegetarian diet and, prior to his illness, took comfrey leaves which are known to contain hepatotoxic pyrrolizidine alkaloids. Comfrey is widely used as a herbal remedy, but so far has only been implicated in two other documented cases of human hepatic veno-occlusive disease. A possible causal association of comfrey and this patient's veno-occlusive disease is suggested by the temporal relationship of the ingestion of comfrey to his presentation, the histological changes in the liver and the exclusion of other known causes of the disease.

All ages and genders are concerned with a peak of incidence in girls in prepubertal age, even if the diseaseTINJAUAN PUSTAKA2has been diagnosed as early as 6 months. Autoimmune hepatitis may be classified in two major subgroups on a presence of a specific set of autoantibodies: smooth muscle antibody (SMA mostly with anti-actin specificity and/or by antinuclear antibody (ANA in type 1 and liver-kidney microsome antibody (LKM1 and/or the anti-liver cytosol in type 2. The histological hallmark is “interface hepatitis”, with a mononuclear cell infiltrate in the portal tracts, variable degrees of necrosis, and progressive fibrosis. The disease follows a chronic but fluctuating course usually progressing to cirrhosis and liver failure.The most frequent type onset is similar to that of an acute viral hepatitis with acute liver failure in some patients; about a third of patients have an insidious onset with progressive fatigue and jaundice while 10-15% are asymptomatic and are accidentally discovered by the finding of hepatomegaly and/or an increase of serum aminotransferase activity. There is a female predominance in both. LKM1-positive patients tend to present more acutely, at a younger age, and commonly have immunoglobulin A (IgA deficiency, while duration of symptoms before diagnosis, clinical signs, family history of autoimmunity, presence of associated autoimmune disorders, response to treatment and long-term prognosis are similar in both groups.Corticosteroids alone or in conjunction with azathioprine are the treatment of choice inducing remission in over 90% of patients. An alternative therapeutic strategy is cyclosporine. Withdrawal of immunosuppression is associated with high risk

    We describe a case of rapidly progressive neonatal diffuse hepatic haemangioendotheliomas. The clinical picture was characterized by respiratory insufficiency due to gross abdominal enlargement, coagulopathy, and the development of cardiovascular insufficiency during the course of disease. Pharmacological, radiotherapeutic and endovascular treatment options all proved ineffective. We describe our own experience and the steps taken to treat this child. Unfortunately, the child died as a consequence of the disease. As cases like this are rare and are associated with severe morbidity and high mortality, more knowledge needs to be gained on infantile hepatic haemangioendotheliomas and their optimal treatment. The use of a web-based data registry could be beneficial. (orig.)

    Diagnosing hepatic injury in HIV infection can be a herculean task for clinicians as several factors may be involved. In this study, we sought to determine the effects of antiretroviral therapy (ART) and disease progression on hepatic enzymes in HIV patients. A case-control study conducted from January to May 2014 at the Akwatia Government Hospital, Eastern region, Ghana, The study included 209 HIV patients on ART (designated HIV-ART) and 132 ART-naive HIV patients (designated HIV-Controls). Data gathered included demography, clinical history and results of blood tests for hepatic enzymes. We employed the Fisher's, Chi-square, unpaired t-test and Pearson's correlation in analysis, using GraphPad Prism and SPSS. A P value 0.05). There was a significant positive correlation between hepatic enzymes (ALP, ALT, AST and GGT) for both groups (p enzymes for both groups was small. Antiretroviral therapy amongst this population has minimal effects on hepatic enzymes and does not suggest modifications in therapy. Hepatic injury may occur in HIV, even in the absence of ART and other traditional factors. Monitoring of hepatic enzymes is still important in HIV patients.

    Fascioliasis is a zoonotic disease that can sometimes affect humans. It presents with non-specific signs and symptoms which makes it difficult to establish an early definitive diagnosis. This can be particularly true in non-endemic countries where a high degree of suspicion is needed to make the diagnosis. Another confounding factor is that many of the initial complains and findings are very similar to those of malignancy. We report a case of an otherwise healthy 47 year-old male presenting with abdominal pain, night-time sweating, anorexia, weight loss and loose stools that had several hepatic nodules visible in the abdominal CT scan. Although the initial hypothesis was hepatic malignancy or liver metastasis of unknown primary neoplasm, the workup performed led us to the correct diagnosis. He was treated successfully for hepatic fascioliasis, with a full recovery. © BMJ Publishing Group Ltd (unless otherwise stated in the text of the article) 2017. All rights reserved.

    We report here a case of recurrent paratyphoid fever A with hepatitis A co-infection in a patient with chronic hepatitis B. A 26-year-old male patient, who was a hepatitis B virus carrier, was co-infected with Salmonella enterica serovar Paratyphi A and hepatitis A virus. The recurrence of the paratyphoid fever may be ascribed to the coexistence of hepatitis B, a course of ceftriaxone plus levofloxacin that was too short and the insensitivity of paratyphoid fever A to levofloxacin. We find that an adequate course and dose of ceftriaxone is a better strategy for treating paratyphoid fever. Furthermore, the co-infection of paratyphoid fever with hepatitis A may stimulate cellular immunity and break immunotolerance. Thus, the administration of the anti-viral agent entecavir may greatly improve the prognosis of this patient with chronic hepatitis B, and the episodes of paratyphoid fever and hepatitis A infection prompt the use of timely antiviral therapy.

    Hepatic steatosis is a highly prevalent liver disease, yet research is hampered by the lack of tractable cellular and animal models. Steatosis also occurs in cats, where it can cause severe hepatic failure. Previous studies demonstrate the potential of liver organoids for modeling genetic diseases.

    Full Text Available Gallbladder (GB stones have been associated with several metabolic factors and liver diseases. This community-based study aimed at investigating the prevalence rate of GB stones and its associated factors in a hepatitis B virus (HBV/hepatitis C virus (HCV-endemic township in southern Taiwan. A total of 1701 residents (689 males and 1012 females; mean age: 51.2 ± 16.0 years were enrolled in this prospectively designed screening project. Serum biochemistry tests, including testing for levels of serum aspartate aminotransferase, alanine aminotransferase (ALT, hepatitis B surface antigen (HBsAg, and antibody to HCV (anti-HCV were conducted. In addition, a hepatobiliary ultrasonographic (US examination was also conducted. Of the 1701 residents, 243 (14.3% and 475 (27.9% were found to be positive for HBsAg and anti-HCV, respectively. Results of the US examination revealed the prevalence rate of GB stone and fatty liver to be 6.8% and 55.6%, respectively. Using univariate analyses we found that significantly higher proportions of the participants with GB stone were male, over 50 years of age, positive for anti-HCV (p = 0.001, p 50 year were identified as independent factors associated with the formation of GB stones. Anti-HCV was associated with GB stones in males but not in females in both univariate and multivariate analyses. GB stones were found to have a prevalence rate of 6.8% in this HCV/HBV hyperendemic township and are associated with higher mean age. A correlation between chronic hepatitis C and GB stones is observed only among males.

    To assess the role of altered hepatic folate metabolism in the pathogenesis of the folate deficiency of chronic alcoholism, the hepatic metabolism of a tracer dose of 3 H-PteGlu was compared in monkeys given 50% of energy as ethanol for 2 years and in control monkeys. Long-term ethanol feeding resulted in mild hepatic injury, with a significant decrease in hepatic folate levels. Chromatographic studies of liver biopsies obtained after the tracer dose indicated that the processes of reduction, methylation, and formylation of reduced folate and the synthesis of polyglutamyl folates were not affected by long-term ethanol feeding. Hepatic tritium levels were significantly decreased in the ethanol-fed group. These studies suggest that the decrease in hepatic folate levels observed after long-term ethanol ingestion is due to a decrease in hepatic folate levels observed after long-term ethanol ingestion is due to a decreased ability to retain folates in the liver, whereas reduction and further metabolism of folates is not affected

    Objective: To explore the diagnostic and therapeutic efficacy of interventional procedure for upper gastrointestinal bleeding in patients of hepatic carcinoma accompanied with hepatic artery-portal vein shunting (HAPVS). Methods: Clinical data of 27 patients of hepatic carcinoma accompanied with HAPVS were retrospectively analyzed. All patients underwent hepatic arterial angiography and transcatheter arterial embolization. Shunts were embolized with coils, Gelfoam particles or PVA particles. Results: Of 27 patients with upper gastrointestinal bleeding, central type HAPVS was seen in 16 and peripheral type HAPVS in 11. Reversed portal venous flow was detected in 20 cases and ascites was found in 23 cases. The abnormal shunts were successfully occluded in all patients and the bleeding ceased within 2 days after embolization. No recurrent bleeding occurred in one month after the treatment. Ascites disappeared in 16 cases and subsided in 7 cases. Conclusion: HAPVS is an important cause for upper gastrointestinal bleeding in patients of hepatic carcinoma, and the arteriovenous fistula can be confirmed with hepatic artery DSA. Embolization of fistulous orifice is the most effective therapy for such patients. (authors)

    Full Text Available Amebiasis can be considered the most aggressive disease of the human intestine, responsible in its invasive form for clinical syndromes, ranging from the classic dysentery of acute colitis to extra-intestinal disease, with emphasis on hepatic amebiasis, unsuitably named amebic liver abscess. Found worldwide, with a high incidence in India, tropical regions of Africa, Mexico and other areas of Central America, it has been frequently reported in Amazonia. The trophozoite reaches the liver through the portal system, provoking enzymatic focal necrosis of hepatocytes and multiple micro-abscesses that coalesce to develop a single lesion whose central cavity contains a homogeneous thick liquid, with typically reddish brown and yellow color similar to "anchovy paste". Right upper quadrant pain, fever and hepatomegaly are the predominant symptoms of hepatic amebiasis. Jaundice is reported in cases with multiple lesions or a very large abscess, and it affects the prognosis adversely. Besides chest radiography, ultrasonography and computerized tomography have brought remarkable contributions to the diagnosis of hepatic abscesses. The conclusive diagnosis is made however by the finding of Entamoeba histolytica trophozoites in the pus and by the detection of serum antibodies to the amoeba. During the evolution of hepatic amebiasis, in spite of the availability of highly effective drugs, some important complications may occur with regularity and are a result of local perforation with extension into the pleural and pericardium cavities, causing pulmonary abscesses and purulent pericarditis, respectively The ruptures into the abdominal cavity may lead to subphrenic abscesses and peritonitis. The treatment of hepatic amebiasis is made by medical therapy, with metronidazole as the initial drug, followed by a luminal amebicide.
