Full Text Available OBJETIVO: En Venezuela las trabajadoras sexuales reciben un control sanitario para la sífilis y el virus de inmunodeficiencia humana (VIH. Sin embargo, otras importantes infecciones de transmisión sexual no son evaluadas. Así, se realizó este estudio con el objetivo de determinar el nivel socio-cultural de un grupo de trabajadores sexuales y su relación con la sero-presencia de marcadores de Hepatitis C y Hepatitis B, en adición a la evaluación de rutina. MÉTODOS: Se evaluaron 212 trabajadoras sexuales, que acudieron al control sanitario en el servicio de infecciones de transmisión sexual, de la ciudad de Los Teques, Venezuela. Fueron entrevistadas en cuanto a edad, nivel educativo, uso de anticonceptivos y del condón. Se les tomó una muestra de sangre para determinar sífilis, antígeno de superficie de hepatitis B (HBsAg y la presencia de anticuerpos contra el core de hepatitis B (anti-HBc, virus de hepatitis C (anti-HC y VIH. Los datos fueron evaluados estadísticamente por Chi-cuadrado y correlación de Pearson. RESULTADOS: La prevalencia fue de 2,4% para sífilis, 0,5% para anti-HC, 3,8% para HBsAg y 13,8% para anti-HBc. Un aumento en la prevalencia de marcadores de hepatitis B se correlacionó con un bajo nivel educativo (p<0,05 e incremento en la edad (p<0,05. No se encontró ningún caso positivo de VIH. La encuesta reveló que el 38,5% de las trabajadoras sexuales nunca utilizan el condón y un 25,6% de ellas no utiliza ningún tipo de método anticonceptivo. CONCLUSIONES: Es necesario implementar planes de inmunización de hepatitis B en este grupo de mujeres, así como campañas de educación sobre la importancia del uso del condón para disminuir la probabilidad de contraer infecciones de transmisión sexual.

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.

Hepatitis B reactivation and current clinical impact Reactivación de la hepatitis B y su impacto clínico actual

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.

Hepatic angiosarcoma: Presentation of two cases Angiosarcoma hepático: Presentación de dos casos

Full Text Available Hepatic angiosarcoma is a rare primary tumor of the liver with a mesenchymal origin. Diagnosis is difficult because clinical manifestations and imaging studies are inconclusive. In many cases a diagnosis is obtained during necropsy, not being apparent during the course of disease. It is associated with several risk factors, but these contribute to explaining only a few of all reported cases. When clinical manifestations begin progression is often fast, and possibilities for curative treatment are limited. We report two cases of hepatic angiosarcoma. In the first one, our patient had an insidious initial course, and then suddenly presented with hepatic failure followed by acute respiratory distress. A diagnosis was reached during necropsy. In the second case, we initiated the study of a chronic liver disease using fine-needle aspiration biopsy, which showed findings suggestive of hepatic angiosarcoma. In the following weeks the patient started on a torpid clinic course, and died from multiple organ failure.El angiosarcoma hepático es una neoplasia de estirpe mesenquimal de baja frecuencia y difícil diagnóstico por su forma inespecífica de manifestarse clínica y radiológicamente. Tanto es así que muchos diagnósticos se obtienen mediante necropsia, no siendo posible poner de manifiesto la enfermedad durante su curso. Se asocia a diferentes agentes etiológicos, pero en la mayoría de los casos no es posible establecer una exposición concreta a ninguno de ellos. Cuando comienza a manifestarse, la evolución suele ser rápida y las opciones de tratamiento curativo son escasas. Presentamos en nuestro trabajo dos casos de angiosarcoma hepático. En el primero, el paciente sufre en principio una evolución insidiosa, presentando al fin, y de forma abrupta, un cuadro de insuficiencia hepática seguido de distrés respiratorio, falleciendo por este motivo. El diagnóstico se alcanza en la necropsia. En el segundo caso se inicia un estudio de

Full Text Available Objective. To analyze factors associated with hepatitis B immunization adherence among adolescents attending a sexually transmitted disease (STD clinic in El Paso, a city in Texas that is on the border between Mexico and the United States of America. Methods. In this cohort study with 248 adolescents we obtained data on demographics and health beliefs through personal interviews and medical record abstraction. We monitored each of the individuals for 8 months to determine whether the adolescents received a first, second, and third dose of the hepatitis B vaccine. Results. Overall, 32% of the adolescents received the first immunization, 9% the second, and 2% the third. The strongest predictor of receiving either one or two doses was providing the vaccine at the STD clinic as opposed to referring adolescents to a separate vaccination clinic (relative risk (RR for receiving the first immunization = 7.3; RR for receiving the second immunization = 3.8. Several health beliefs were also associated with receiving vaccinations. Conclusions. The results of our study indicate that hepatitis B vaccination programs can be improved through such steps as providing vaccinations at a convenient site, educating adolescents about hepatitis B risk factors, and emphasizing the difficulty of treating hepatitis B infection.Objetivo.

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.

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.

Primary hepatic artery embolization in pediatric blunt hepatic trauma.

Science.gov (United States)

Ong, Caroline C P; Toh, Luke; Lo, Richard H G; Yap, Te-Lu; Narasimhan, Kannan

2012-12-01

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.

• METHODS: In a cross sectional study, serum of 103 hepatitis C cases (79.6% men and 20.4% women were analyzed for s, x and core genes via a nested polymerase chain reaction technique.
• RESULTS: HBV DNA was detectable in serum of 20 patients (19.4%. No significant difference in age, sex and route of transmission were seen in HBV DNA positive and negative patients. In HBV DNA positive and negative groups, mean of AST was 73, 47 (p < 0.05 and mean of ALT was 76 and 36 respectively (p < 0.05.
• CONCLUSION: Occult hepatitis B was observed in a considerable number of hepatitis C patients in Tehran. It was associated with elevation in liver enzyme but was not related to route of transmission.
• KEY WORD: Occult hepatitis B, hepatitis C, cirrhosis.

Hepatic artery infusion (HAI) for hepatic metastases in combination with hepatic resection and hepatic radiation

International Nuclear Information System (INIS)

Merrick, H.W.; Dobelbower, R.R.; Ringleint, J.F.; Skeel, R.T.

1986-01-01

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 Objectives : Epidemiologic data of HIV and viral hepatitis coinfection are needed in sub-Saharan Africa to guide health policy for hepatitis screening and optimized antiretroviral therapy (ART. Materials and Methods: We screened 323 HIV-infected, ART-eligible adults for hepatitis B surface antigen (HBsAg and hepatitis C antibody (HCV Ab at a tertiary hospital in Lusaka, Zambia. 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.

2014-01-01

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...

Hepatic encephalopathy associated with hepatic lipidosis in llamas (Lama glama).

Science.gov (United States)

Pillitteri, C A; Craig, L E

2013-01-01

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.

Usefulness of screening ultrasonography for hepatocellular carcinoma detection: chronic hepatitis versus hepatic cirrhosis caused by hepatitis B virus

Chang, Sam Uel; Choi, Don Gil; Lim, Jae Hoon

2004-01-01

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

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.

1995-01-01

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.

Cost-effectiveness of hepatitis A vaccination for individuals with chronic hepatitis C.

Science.gov (United States)

Chapko, Michael K; Yee, Helen S; Monto, Alexander; Dominitz, Jason A

2010-02-17

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.

Hepatitis E virus and fulminant hepatitis--a virus or host-specific pathology?

Science.gov (United States)

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.

2007-01-01

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)

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.

[Viral hepatitis in travellers].

Science.gov (United States)

Abreu, Cândida

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

2010-01-01

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.

Özden, Hale T

2016-03-01

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.

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)

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

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.

-B.OBJETIVO: Comparar dos vacunas pediátricas recombinantes contra la hepatitis B -Euvax-B y la vacuna de referencia Engerix-B- en cuanto a su inmunogenicidad y reactogenicidad, e investigar su intercambiabilidad, es decir, si el esquema de vacunación contra la hepatitis B de tres dosis comenzado con una primera dosis de Engerix-B puede completarse con dos dosis de Euvax-B. MÉTODOS: Este estudio se llevó a cabo en la ciudad de Córdoba, Argentina, entre marzo de 1999 y febrero de 2000. Se vacunó contra la hepatitis B a tres grupos de 100 lactantes argentinos a los 0, 1 y 6 meses de edad. El grupo A recibió tres dosis de Euvax-B; el grupo B, tres dosis de Engerix-B; y el grupo C, una dosis de Engerix-B seguida de dos dosis de Euvax-B. Para evaluar la reactogenicidad se utilizó la información brindada por los padres acerca de determinados fenómenos locales o sistémicos solicitados por los investigadores que hubieran ocurrido durante los siete días posteriores a la vacunación. Para establecer si eran idénticas clínicamente las vacunas Euvax-B y Engerix-B se utilizaron las tasas de seroprotección -es decir, títulos de anticuerpos contra el antígeno de superficie de hepatitis B (anti-HBsAg > 10 miliunidades internacionales por mililitro (mUI/mL- alcanzados dos meses después de la tercera dosis. RESULTADOS: La reactogenicidad fue baja en los tres grupos de estudio. A los 5 meses de la segunda dosis (es decir, inmediatamente antes de la tercera dosis, las tasas de seroprotección fueron 95,9%, 94,7% y 90,2% en los grupos A, B y C, respectivamente. Dos meses después de la tercera dosis, todos los lactantes se encontraban protegidos, con concentraciones medias geométricas de anti-HBsAg de 2 468,1 mUI/mL en el grupo A, de 1 714,8 mUI/mL en el grupo B y de 2 075,3 mUI/mL en el grupo C. CONCLUSIONES: Las dos vacunas recombinantes contra la hepatitis B estudiadas fueron bien toleradas y altamente inmunogénicas. La vacuna Euvax-B fue clínicamente idéntica (no inferior a la

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.

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.

In a patient undergoing selective hepatic arteriography for suspected liver trauma, a nonopacified area of the liver, initially thought to represent a hepatic hematoma, was later discovered to be due to the presence of an accessory right hepatic artery arising from the superior mesenteric artery. This case illustrates the need for a search for aberrant vasculature whenever a liver hematoma is suspected on the basis of a selective hepatic arteriogram. (orig.) [de

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.

Julio Mayca P

2004-10-01

Full Text Available La infección por hepatitis B es un problema de salud pública a nivel mundial. El Perú, ubicado en una zona de endemicidad intermedia, no es ajeno a esta realidad. El propósito del presente artículo es presentar la evolución de las investigaciones sobre dicha enfermedad, se revisaron 60 referencias (1970-2002, no se observó una secuencia en las investigaciones sobre prevalencia, además se usaron distintos marcadores. Los resultados sobre la presencia del HBsAg variaron entre costa (0-4,8%, sierra (13,8-16% y selva (3-17,1%, sin tener investigaciones globales. Sobre los estudios en grupos de riesgo, las guarniciones militares en zona de selva han reportado brotes e identificado al HbsAg hasta en 43,2% de su población. En trabajadoras sexuales, los estudios muestran prevalencia en los marcadores de 51,5 a 89,3%. En personal de salud, se reportó el HBsAg entre 0 y 7,8%, teniendo los servicios de banco de sangre, nefrología, odontología y gastroenterología, mayor número de casos. Las investigaciones sobre respuesta serológica a la aplicación de vacunas se iniciaron en 1987, en comunidades nativas selváticas; posteriormente se aplicó un programa piloto apoyado por OPS/OMS en Abancay. Desde 1996, el MINSA estableció inmunizaciones a menores de un año en zonas de alta y mediana endemicidad, ampliando el 2003 la vacunación de este grupo a todo el país. Se concluye que a pesar de los avances en el control de la hepatitis B, se requiere una visión conjunta de todos los sectores involucrados para establecer acciones concretas y continuas tanto en análisis de costos, epidemiología y educación.

Hepatitis A Virus and Hepatitis E Virus: Emerging and Re-Emerging Enterically Transmitted Hepatitis Viruses.

Science.gov (United States)

Lemon, Stanley M; Walker, Christopher M

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.

The hepatic bridge.

Science.gov (United States)

Sugarbaker, Paul H

2018-07-01

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%

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.

Identification of acute self-limited hepatitis B among patients presenting with hepatitis B virus-related acute hepatitis: a hospital-based epidemiological and clinical study.

Science.gov (United States)

Han, Y-N

2009-01-01

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.

Recurrent paratyphoid fever A co-infected with hepatitis A reactivated chronic hepatitis B.

Science.gov (United States)

Liu, Yanling; Xiong, Yujiao; Huang, Wenxiang; Jia, Bei

2014-05-12

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.

Primary hepatic lymphoma presenting as fulminant hepatic failure with hyperferritinemia: A case report

Directory of Open Access Journals (Sweden)

Haider Fyeza S

2008-08-01

Full Text Available Abstract Introduction Primary hepatic lymphoma is an unusual form of non-Hodgkin's lymphoma that usually presents with constitutional symptoms, hepatomegaly and signs of cholestatic jaundice. Diffuse hepatic infiltration is uncommon and presentation with acute hepatic failure even more rare. The presence of markedly elevated ferritin levels can complicate the evaluation process and suggest alternative diagnoses. We present the case of a middle-aged woman exhibiting pancytopenia, hyperferritinemia and rapidly deteriorating to develop acute hepatic failure. Her initial clinical picture led to a working diagnosis of adult onset Still's disease with probable hemophagocytic syndrome before her worsening liver function necessitated a percutaneous liver biopsy and establishment of the final diagnosis of primary hepatic lymphoma. Conclusion Primary hepatic lymphoma is an uncommon malignancy and its manifestation as progressive hepatitis or acute fulminant hepatic failure can be difficult to diagnose. The presence of constitutional symptoms, pancytopenia and high ferritin levels can complicate the evaluation process. A liver biopsy early in the course of liver dysfunction may establish the diagnosis without a higher risk of bleeding complications seen once liver failure sets in.

Full Text Available RESUMEN: Introducción: La hepatitis C es uno de los grandes problemas de salud pública en el mundo, especialmente por su alta transmisibilidad por vía inyectada. Objetivo: Identificar la prevalencia de la infección por VHC, y factores asociados en usuarios de drogas psicoactivas inyectables en tres ciudades (Armenia, Bogotá y Cúcuta de Colombia. Métodos: Estudio descriptivo transversal en 668 usuarios de drogas inyectables captados a través de muestreo guiado por el respondiente, a quienes se indagó sobre características demográficas y comportamientos de riesgo. Se utilizó la prueba de Anticuerpos, tomado en papel de filtro y se confirmaron los casos de VHC, con pruebas de carga viral de RNA. Se estimó la prevalencia de VHC y los factores asociados con pruebas estadísticas Chi-cuadrado y se calcularon razones de prevalencia crudas y ajustadas con regresión logística usando RDSAT y SPSS. Resultados: La prevalencia de infección por VHC fue del 17,5% y se encontraron como factores que aumentan la prevalencia de hepatitis: tener VIH, inyectarse con otra persona portadora del virus, utilizar dosis de una jeringa que estaba compartiendo, inyectarse con una jeringa casera y consumir marihuana. Como factor que reduce la prevalencia, el adquirir jeringas en droguerías u otras tiendas. Conclusión: Se evidencia un consumo establecido de drogas por vía inyectada, poniendo de relieve la importancia de generar intervenciones para la reducción de daños y la prevención de hepatitis C en estas tres ciudades del país.

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.

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.

Hepatitis E virus has emerged as a public health problem, particularly in developing countries. The four genotypes identified in mammals include the G3 found in indigenous hepatitis in countries and regions with high porcine population, and the G1, associated with maternal deaths.  To determine coinfection by hepatitis E virus and the circulating genotypes in Colombia in 1,097 samples using serological markers for hepatitis A, B and C.  Serum samples of 1,097 patients from different regions of Colombia stored at the Laboratorio de Virología of the Instituto Nacional de Salud were selected to detect IgG and IgM anti-hepatitis E virus antibodies. The viral genomes of positive samples were amplified by RT-PCR, and the products were sequenced and phylogenetically analyzed by comparing ORF2 sequences deposited in the GenBank.  IgG anti-hepatitis E virus antibodies were found in 278 samples, IgM in 62, and both markers in 64. Hepatitis E virus and hepatitis A virus coinfection determined by IgG anti-hepatitis E virus was 33.6% and 16.1% by IgM; hepatitis E virus and hepatitis B virus coinfection was 23.4% and 8.1%, and hepatitis E virus and hepatitis C virus coinfection was 35.4% and 5.83%, respectively. Among the 52 positive samples by PCR nine were sequenced and grouped within genotype 3A of the American porcine strain.  The highest seropositivity was observed for hepatitis A and E. The incidence of hepatitis E virus coinfection with other hepatotropic viruses indicated that this pathogen is more frequent than expected. The circulation of genotype 3A implies that this disease may occur in outbreaks and as zoonosis in Colombia.

Hepatitis A virus (HAV) can cause significant pathology in patients with chronic hepatitis B virus (HBV), however, HAV can be prevented by vaccination. The aim of this study was to determine the implication of vaccination against HAV vaccine in patients with chronic hepatitis B. The seroprevalence of anti-HAV IgG antibodies was investigated in the patients with chronic hepatitis B. Anti-HAV IgG antibodies were detected by commercially available ELISA kit. A total of 673 patients (354 males, 319 females with age range of 17-78 years) with chronic hepatitis B were included the study. Hepatitis A virus seropositivity rate was 34% in the patients younger than 20 years, 79% in the age group of 20 to 29 years, and 100% after 35 years of age. Hepatitis A virus vaccination may be recommended for young adult patients with chronic hepatitis B in Turkey. Tulek N, Ozsoy M, Moroglu C, Sonmezer MC, Temocin F, Ertem GT, Erdinc FS.

Giant cell hepatitis (GCH) in adults is a rare event. The diagnosis of GCH is based on findings of syncytial giant hepatocytes. It is commonly associated with either viral infection or autoimmune hepatitis type I. A patient with GCH due to autoimmune hepatitis type II (LKM1+) is described, a combination that has not been previously reported. Corticosteroid therapy was effective in decreasing serum liver enzymes; however, the patient deteriorated rapidly and developed subfulminant hepatic failure. Although an emergency orthotopic liver transplantation was performed, the patient died because of reperfusion injury. Interestingly, only a few giant hepatocytes were noted in the explanted liver. This case stresses the association of GCH with autoimmune disorders, the possible immune mechanism involved in the formation of giant cell hepatocytes, and illustrates the rapidly progressive course and unfavorable prognosis that these patients can develop.

Full Text Available Hepatic encephalopathy can be a serious complication of acute liver failure and chronic liver diseases, predominantly liver cirrhosis. Hyperammonemia plays the most important role in the pathogenesis of hepatic encephalopathy. The brain-blood barrier disturbances, changes in neurotransmission, neuroinflammation, oxidative stress, GABA-ergic or benzodiazepine pathway abnormalities, manganese neurotoxicity, brain energetic disturbances, and brain blood flow abnormalities are considered to be involved in the development of hepatic encephalopathy. The influence of small intestine bacterial overgrowth (SIBO on the induction of minimal hepatic encephalopathy is recently emphasized. The aim of this paper is to present the current views on the pathogenesis of hepatic encephalopathy.

Hepatitis A and hepatitis E are not limited to tropical countries but are also present in industrialized countries. Both infections share similar clinical features. There is no comparative study evaluating the clinical parameters of autochthonous and imported hepatitis A virus and hepatitis E virus infections. The aim of this study was to determine differences between autochthonous and imported hepatitis A virus (HAV) and hepatitis E virus (HEV) infections. Medical charts of all patients at our center with acute HAV and HEV infections were analyzed retrospectively (n = 50, study period 01/2009 - 08/2013). Peak bilirubin (median 8.6 vs. 4.4 mg/dL, p = 0.008) and ALT levels (median 2998 vs. 1666 IU/mL, p = 0.04) were higher in patients with hepatitis A compared to hepatitis E. In comparison to autochthones hepatitis E cases, patients with imported infections had significantly higher peak values for AST, ALT, bilirubin and INR (p = 0.009, p = 0.002, p = 0.04 and p = 0.049, respectively). In HAV infection, AST levels tended to be higher in imported infections (p = 0.08). (i) It is not possible to differentiate certainly between acute HAV and HEV infections by clinical or biochemical parameters, however, HAV infections might be associated with more cholestasis and higher ALT values. (ii) Imported HEV infections are associated with higher transaminases, INR and bilirubin levels compared to autochthonous cases and (iii) imported HAV infections tend to be associated with higher transaminases in comparison to autochthonous cases. © Georg Thieme Verlag KG Stuttgart · New York.

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)

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)

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.)

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.

Hepatitis E is considered to be a worldwide public health problem. Although the prevalence of hepatitis E virus (HEV) antibodies in healthy individuals is noted to be 11%, no patients with acute hepatitis E have previously been identified in Mongolia. Three hundred two consecutive patients (183 males and 119 females; median age of 22.0 [Interquartile range: 18.3-25.0] years) who were clinically diagnosed with sporadic acute hepatitis during 2012-2013 in Ulaanbaatar, Mongolia, were studied. By serological and/or molecular approaches, 77 (25.5%), 93 (30.8%), 19 (6.3%), 48 (15.9%), and 12 (4.0%) of the patients were diagnosed with acute hepatitis of types A, B, C, D (superinfection of hepatitis delta virus on a background of chronic hepatitis B virus infection) and E, respectively, while the cause of hepatitis was unknown in the remaining 53 patients (17.5%). The 12 hepatitis E patients had no history of travel abroad in the 3 months before the onset of disease, and lived separately in fixed or movable houses with water supplied via pipe, tank or well, denying transmission from a common water supply. The 12 HEV isolates obtained from the patients showed high nucleotide identities of 99.7-100%, and a representative HEV isolate, MNE13-227, was closest to the Chinese isolates of genotype 4, with the highest identity of 97.3% in the 304-nt ORF2 sequence and 92.1% over the entire genome. The present study revealed the occurrence of autochthonous acute hepatitis E in Mongolia, caused by a monophyletic genotype 4 HEV strain. © 2015 Wiley Periodicals, Inc.

Hepatic encephalopathy. Imaging Findings

Carrillo, Maria Claudia; Bermudez Munoz, Sonia; J Morillo, Anibal

2007-01-01

Hepatic encephalopathy occurs in patients with chronic hepatic insufficiency and can produce abnormalities in the central nervous system, which can be observed in MRI studies. Traditionally, these imaging findings include symmetrical hyper intensities in T1-weighted sequences in the basal ganglia (mainly globus pallidus), involving also the substantia nigra, mesencephalic tegmentum, frontal and occipital cortex. These areas appear of normal intensity in T2-weighted imaging sequences. Other entities that can lead to similar findings include manganese intoxication and type-1 neurofibromatosis. Currently, with the advent of MR spectroscopy, abnormalities in patients with clinical and subclinical hepatic encephalopathy have been described. After hepatic transplantation, hyper intensities of the basal ganglia and the MR spectroscopic findings may disappear within 3 months to 1 year, suggesting a functional, more than a structural damage. This article will demonstrate the MR findings of patients with hepatic encephalopathy due to chronic hepatic insufficiency.

Epidemiology of viruses causing chronic hepatitis among populations from the Amazon Basin and related ecosystems Epidemiología de las hepatitis crónicas con carácter vírico en las comunidades indígenas de la cuenca amazónica y de otros ecosistemas similares

Full Text Available On the last twenty years, viral hepatitis has emerged as a serious problem in almost all the Amerindian communities studied in the Amazon Basin and in other Amazon-related ecological systems from the North and Center of South America. Studies performed on communities from Bolivia, Brazil, Colombia, Peru and Venezuela have shown a high endemicity of the hepatitis B virus (HBV infection all over the region, which is frequently associated to a high prevalence of infection by hepatitis D virus among the chronic HBV carriers. Circulation of both agents responds mainly to horizontal virus transmission during childhood through mechanisms that are not fully understood. By contrast, infection by hepatitis C virus (HCV, which is present in all the urban areas of South America, is still very uncommon among them. At the moment, there is not data enough to evaluate properly the true incidence that such endemicity may have on the health of the populations affected. Since viral transmission might be operated by mechanisms that could not be acting in other areas of the World, it seems essential to investigate such mechanisms and to prevent the introduction of HCV into these populations, which consequences for health could be very serious.A lo largo de los últimos veinte años, las hepatitis víricas se han revelado como un importante problema para las comunidades indígenas de la cuenca amazónica y de otros ecosistemas similares del norte y centro de Sudamérica. Los estudios realizados en comunidades de Bolivia, Brasil, Colombia, Perú y Venezuela han demostrado una alta propensión endémica para la infección por el virus de la hepatitis B, que se asocia con frecuencia a una elevada prevalencia de coinfección con el virus de la hepatitis D entre los portadores crónicos. La circulación de ambos agentes responde a su transmisión horizontal durante la infancia, a través de mecanismos aún poco conocidos. Por el contrario, la infección por el virus de la

[Latest Treatment of Viral Hepatitis--Overcoming Hepatitis C and Reactivation of Hepatitis B].

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. [

A study on branching patterns of middle hepatic artery was performed in 109 patients with A-P and oblique view hepatic angiogram, which refereed to size and location of quadrate lobe in CT and SMA photography. We could analyze the branching patterns of middle hepatic artery (MHA) in 100 among 109 patients. MHA arising as a first branch of left hepatic artery was the most common pattern (50%), and MHA arising from proper hepatic artery separately on from left hepatic artery was the next common pattern (35%). MHA originating from left gastric artery, or from anterior or posterior of the right hepatic artery was not seen. MHA was not found as an accessory or replaced artery except as replaced common hepatic artery

Hepatitis B and C are two potentially life threatening liver infections. Lebanon is ranked as a zone of moderate endemicity. This study aimed to determine the prevalence of hepatitis B and C in Lebanon and their distribution according to age, region and sex. This national prospective cross-sectional study was conducted from January 2011 till December 2012 in the six Lebanese Governorates in collaboration with municipalities, the Ministry of Public Health, Health Centres and dispensaries. An upcoming screening for hepatitis B and C was announced? in different districts of each Governorate. All individuals presenting to local laboratory, not known to have chronic hepatitis, were asked for a blood sample and answered a questionnaire addressing sex, age, place of birth and residence. Screening tests were "Abbots" for hepatitis B and "Human Hexagon" for hepatitis C. PCR testing was used to confirm the positivity of the previous tests. Of 31147 individuals screened, 542 had a rapid test positive for HBV (prevalence 1.74%, 95% CI 1.6-1.89) with a male to female ratio of 1.08. This prevalence was higher in the South and Nabatieh (1.9%) compared to Beirut (0.73%). Of 31,147 individuals screened, 64 had a rapid test positive for HCV (prevalence 0.21%, 95% CI 0.16-0.27) with a male to female ratio of 0.85. This prevalence was higher in Nabatieh (0.61%) compared to Mount Lebanon (0.08%). The prevalence of HBV and HCV in Lebanon is 1.74% and 0.21%, respectively with a higher prevalence in South and Nabatieh districts. These data rank Lebanon amongst countries with low endemicity for both viruses. Decrease in the prevalence of HBV is due to awareness campaign as well as success of the MOPH National Hepatitis Program in vaccinating all new born since 1998 and in screening and vaccinating high risk groups.

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

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)

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.

Full Text Available Since the first description of feline hepatic lipidosis occurred in 1977, it becames the most diagnosed liver disease in cats. Several factors have been proposed as causes of disease, and obesity being a predisposing factor. 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.

Full Text Available Acute viral hepatitis affects all ages worldwide. Hepatitis E virus (HEV is increasingly recognized as a major cause of acute hepatitis in Europe. Because knowledge of its characteristics is limited, we conducted a retrospective study to outline demographic and clinical features of acute HEV in comparison to hepatitis A, B and C in Lothian over 28 months (January 2012 to April 2014. A total of 3204 blood samples from patients with suspected acute hepatitis were screened for hepatitis A, B and C virus; 913 of these samples were also screened for HEV. Demographic and clinical information on patients with positive samples was gathered from electronic patient records. Confirmed HEV samples were genotyped. Of 82 patients with confirmed viral hepatitis, 48 (59% had acute HEV. These patients were older than those infected by hepatitis A, B or C viruses, were more often male and typically presented with jaundice, nausea, vomiting and/or malaise. Most HEV cases (70% had eaten pork or game meat in the few months before infection, and 14 HEV patients (29% had a recent history of foreign travel. The majority of samples were HEV genotype 3 (27/30, 90%; three were genotype 1. Acute HEV infection is currently the predominant cause of acute viral hepatitis in Lothian and presents clinically in older men. Most of these infections are autochthonous, and further studies confirming the sources of infection (i.e. food or blood transfusion are required.

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

[History of viral hepatitis].

Science.gov (United States)

Fonseca, José Carlos Ferraz da

2010-01-01

The history of viral hepatitis goes back thousands of years and is a fascinating one. When humans were first infected by such agents, a natural repetitive cycle began, with the capacity to infect billions of humans, thus decimating the population and causing sequelae in thousands of lives. This article reviews the available scientific information on the history of viral hepatitis. All the information was obtained through extensive bibliographic review, including original and review articles and consultations on the internet. There are reports on outbreaks of jaundice epidemics in China 5,000 years ago and in Babylon more than 2,500 years ago. The catastrophic history of great jaundice epidemics and pandemics is well known and generally associated with major wars. In the American Civil War, 40,000 cases occurred among Union troops. In 1885, an outbreak of catarrhal jaundice affected 191 workers at the Bremen shipyard (Germany) after vaccination against smallpox. In 1942, 28,585 soldiers became infected with hepatitis after inoculation with the yellow fever vaccine. The number of cases of hepatitis during the Second World War was estimated to be 16 million. Only in the twentieth century were the main agents causing viral hepatitis identified. The hepatitis B virus was the first to be discovered. In this paper, through reviewing the history of major epidemics caused by hepatitis viruses and the history of discovery of these agents, singular peculiarities were revealed. Examples of this include the accidental or chance discovery of the hepatitis B and D viruses.

Hepatic Lipodystrophy in Galloway Calves.

Wieland, M; Mann, S; Hafner-Marx, A; Ignatius, A; Metzner, M

2017-05-01

Hepatic lipodystrophy in Galloway calves is a fatal liver disease affecting a small proportion of the Galloway breed described in different parts of Europe and North America during the past decades. The clinical findings include a diversity of neurological signs. Clinical pathology findings frequently indicate hepatobiliary disease. Postmortem examination reveals an enlarged, pale yellow, and firm liver. Histologic lesions include hepatic fibrosis, hepatic lipidosis, and bile duct hyperplasia. To date, the etiopathogenesis remains obscure. Infectious causes, intoxications, and a hereditary origin have been considered. We describe hepatic lipodystrophy in Galloway calves from an extensively farmed cow-calf operation in southern Germany. Main clinical findings in 6 calves were consistent with hepatic encephalopathy. Clinical pathology findings in 5 of 6 tested animals revealed increased concentration of total bilirubin (maximum value [MV], 54 μmol/l; reference range [RR], 250 U/g Hb). Postmortem examination in 6 calves revealed a firm, diffusely enlarged yellow liver with a finely nodular surface. Histologic lesions included hepatic fibrosis, hepatic lipidosis, and bile duct hyperplasia. Our findings add to the existing data on hepatic lipodystrophy in the Galloway breed and outline a protocol to aid in the diagnosis of this disorder.

Natural history and treatment of hepatitis B virus and hepatitis C virus coinfection

Directory of Open Access Journals (Sweden)

Keeffe Emmet B

2005-09-01

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.

Isolated hepatic tuberculosis without pulmonary or bowel involvement is a diagnostic challenge and can cause considerable morbidity. A young lady from Lahore presented with fever, pain in right hypochondria, nausea and weight loss. CT scan of abdomen showed multiple small hypodense non-enhancing lesions and a heterogeneous texture of liver. Biopsy confirmed the diagnosis of hepatic tuberculosis. It was concluded a case of isolated hepatic tuberculosis without evidence of other primary sites involvement. It is important to consider tuberculosis in the differential diagnosis when suspecting lymphoproliferative or metastatic diseases in a patient with vague symptoms and abnormal hepatic texture on CT.

Full Text Available Viral hepatitis is a major public health problem in many countries all over the world and especially in Middle East, Asia, East-Europe, and Africa. The aim of our study was to assess the incidence of viral hepatitis A, B and C in Qatar and compare it with other countries. This is a retrospective cohort study, which was conducted at Hamad General Hospital, State of Qatar from 2002-2006. Patients who were screened and diagnosed with viral hepatitis were included in this study. The diagnostic classification of definite viral hepatitis was made in accordance with criteria based on the International Classification of Disease tenth revision (ICD-10. A total of 527 cases of hepatitis C, 396 cases of hepatitis B, 162 cases of hepatitis A and 108 cases of unspecified were reported during the year 2006. Reported incidence rate per 10,000 populations during the year 2006 for hepatitis A was 1.9, hepatitis B 4.7, and Hepatitis C 6.3. The proportion of hepatitis B and C was significantly higher in male population than females across the years (2002-2006. Hepatitis A was more prevalent in children below 15 years (72.3%, hepatitis B in adults aged above 15 years, and hepatitis C in the population above 35 years of age. The incidence of hepatitis A has been declining in Qataris and increasing in expatriates. There was a significant relationship in gender and age group of the patients with hepatitis A, B and C. We conclude that hepatitis has become a national health issue in Qatar. The incidence rate of hepatitis in Qatar is comparable to its neighboring countries, United Arab Emirates and Saudi Arabia. There is a need for further research on hepatitis and the associated risk factors.

Moon, K.L. Jr.; Federle, M.P.

1983-01-01

Twenty-five patients with hepatic injury from blunt upper abdominal trauma were examined by computed tomography (CT). The spectrum of CT findings was recorded, and the size of the hepatic laceration and the associated hemoperitoneum were correlated with the mode of therapy used in each case (operative vs nonoperative). While the need for surgery correlated roughly with the size of the hepatic laceration, the size of the associated hemoperitoneum was an important modifying factor. Fifteen patients with hepatic lacerations but little or no hemoperitoneum were managed nonoperatively. CT seems to have significant advantages over hepatic scintigraphy, angiography, and diagnostic peritoneal lavage. By combining inforamtion on the clinical state of the patient and CT findings, therapy of hepatic injury can be individualized and the incidence of nontherapeutic laparotomies decreased

Hepatic fibrosis (HF) is the pathological component of a variety of chronic liver diseases. Hepatic stellate cells (HSC) are the main collagen-producing cells in the liver and their activation promotes HF. If HSC activation and proliferation can be inhibited, HF occurrence and development can theoretically be reduced and even reversed. Over the past ten years, a number of studies have addressed this process, and here we present a review of HSC modulation and HF reversal. - Highlights: • We present a review of the modulation of hepatic stellate cells (HSC) and reversibility of hepatic fibrosis (HF). • HSC are the foci of HF occurrence and development, HF could be prevented and treated by modulating HSC. • If HSC activation and proliferation can be inhibited, HF could theoretically be inhibited and even reversed. • Prevention or reversal of HSC activation, or promotion of HSC apoptosis, immune elimination, and senescence may prevent, inhibit or reverse HF.

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.

Infection with hepatitis viruses can lead to acute hepatitis with the risk of developing liver failure. Chronic viral hepatitis may evolve into liver cirrhosis and hepatocellular carcinoma. Thus, prevention of viral hepatitis and its sequels is essential. Vaccination against hepatitis A is successful in almost all individuals. Protective antibodies maintain for at least 20 years. Booster vaccinations are not necessary. Since the introduction of hepatitis A vaccines, the incidence of new HAV-infections has declined significantly. Hepatitis B vaccines are safe and highly effective. Special populations such as dialysis patients or immunocompromised patients require special vaccine schedules. New vaccines with improved adjuvants are currently being tested in clinical trials. So far there is no hepatitis C vaccine on the horizon. Prophylaxis of HCV-infections relies primarily on hygiene measures. Early therapy of acute hepatitis C can prevent chronic hepatitis C. HDV-infection can only be established if HBsAg is present. Thus, prevention of hepatitis B or elimination of HBsAg means prevention of hepatitis delta. Hepatitis E vaccines have been evaluated in phase III studies. The development of HEV vaccines becomes more relevant since chronic HEV infections have been reported in immunosuppressed individuals.

The significance of hepatitis A virus (HAV) super-infection in patients with chronic hepatitis C had been a matter of debate. While some studies suggested an incidence of fulminant hepatitis A of up to 35%, this could not be confirmed by others. We identified 17 anti-HCV-positive patients with acute hepatitis A from a cohort of 3170 anti-HCV-positive patients recruited at a single center over a period of 12 years. Importantly, none of the anti-HCV-positive patients had a fulminant course of hepatitis A. HCV-RNA was detected by PCR in 84% of the anti-HCV-positive/anti-HAV-IgM-negative patients but only in 65% of anti-HCV-positive patients with acute hepatitis A (p=0.03), indicating suppression of HCV replication during hepatitis A. Previous HAV infection had no effect on HCV replication. After recovery from hepatitis A, an increased HCV replication could be demonstrated for 6 out of 9 patients with serial quantitative HCV-RNA values available while 2 patients remained HCV-RNA negative after clearance of HAV throughout follow-up of at least 2 years. HAV super-infection is associated with decreased HCV-RNA replication which may lead to recovery from HCV in some individuals. Fulminant hepatitis A is not frequent in patients with chronic hepatitis C recruited at a tertiary referral center.

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.

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.

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)

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.

Hepatitis B virus (HBV) may reactivate when treating chronic hepatitis C (CHC) with direct acting antivirals (DAA). We aim to investigate the risk of HBV reactivation during DAA therapy. Chronic hepatitis C patients receiving pan-oral DAA therapy from December 2013 to August 2016 were evaluated. Fifty-seven patients that had a past HBV infection (negative hepatitis B surface antigen [HBsAg] and positive hepatitis B core antibody) and seven patients that had a current HBV infection (positive HBsAg) were enrolled. Serum HBV and hepatitis C virus (HCV) markers were regularly measured. The endpoints were the HCV sustained virological response (SVR) and the HBV virological/clinical reactivation. The overall SVR 12 rate was 96.9%, and two patients, one with positive HBsAg, had a relapse of HCV. No episodes of HBV virological reactivation were observed among the patients with a past HBV infection. For the seven patients with a current HBV infection, HBV virological reactivation was found in four (57.1%) of the seven patients. Clinical reactivation of HBV was observed in one patient with pretreatment detectable HBV DNA and recovered after entecavir administration. For the other three patients with HBV virological reactivation, the reappearance of low level HBV DNA without clinical reactivation was observed. HBsAg levels demonstrated only small fluctuations in all the patients. There was a minimal impact of hepatitis B core antibody seropositivity on HCV efficacy and safety. For CHC patients with current HBV infection, the risk of HBV reactivation was present, and monitoring the HBV DNA level during therapy is warranted. © 2017 Journal of Gastroenterology and Hepatology Foundation and John Wiley & Sons Australia, Ltd.

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.

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 C virus (HCV) has been shown to induce anti-liver-kidney microsomal-1 (LKM1) antibody positive chronic active hepatitis, simulating type 2 autoimmune chronic active hepatitis. The cases of five patients presenting with features of type 1 (antinuclear antibody positive) autoimmune chronic active hepatitis and extrahepatic autoimmune manifestations, in whom immunosuppressive treatment had no effect on liver disease are presented. In these patients, HCV infection could be shown by the presence in serum of anti-HCV antibodies and HCV-RNA detected by polymerase chain reaction. These cases suggest the following: (a) chronic HCV infection can mimic type 1, as well as type 2, autoimmune chronic active hepatitis; (b) HCV infection might be systematically sought in patients presenting with features of type 1 autoimmune chronic active hepatitis, with special care in patients who are unresponsive to immunosuppressive treatment.

Serum hepatitis B core antigen (HBcAg) is an important marker of hepatitis B virus replication. We describe an easy, sensitive radioimmunoassay for determination of HBcAg in detergent-treated serum pellets containing Dane particles. Components of a commercial kit for anticore determination are used, and HBcAG is measured by competitive inhibition of binding of 125 I-labeled antibodies to HBcAg with HBcAg-coated beads. We assayed for HBcAG in the sera of 49 patients with hepatitis B surface antigen (HBsAg)-positive chronic hepatitis, 50 patients with HBsAg-negative chronic hepatitis, and 30 healthy volunteers. HBcAg was detected in 41% of patients with HBsAg-positive chronic hepatitis but not in patients with HBsAg-negative chronic hepatitis. Hepatitis Be antigen (an antigen closely associated with the core of Dane particles) determined in the same sera by radioimmunoassay, was not detected in 50% of HBcAg-positive sera

One hundred ten consecutive patients (60 males and 50 females; age, mean +/- standard deviation [SD], 22.6 +/- 6.4 years; range 16-48 years) who were clinically diagnosed with sporadic acute hepatitis between December 2004 and January 2005 in Ulaanbaatar, Mongolia, were studied. IgM antibodies to hepatitis A virus were detected in 18 patients (16.4%), IgM antibodies to hepatitis B core (anti-HBc IgM) in 38 patients (34.5%) including two patients with concurrent hepatitis delta virus (HDV) infection, and hepatitis C virus RNA in nine patients (8.2%). There were 30 hepatitis B virus (HBV) carriers who had detectable hepatitis B surface antigen and antibodies to HDV but were negative for anti-HBc IgM, suggesting that they acquired type D acute hepatitis due to superinfection of HDV on a background of chronic HBV infection. None had IgM antibodies to hepatitis E virus (HEV). Consequently, 16.4, 32.7, 6.4, 1.8, and 27.3% of the patients were diagnosed as having acute hepatitis of type A, B, C, type B + D (HBV/HDV coinfection), and type D (superinfection of HDV), respectively. The cause of hepatitis was not known in the remaining 17 patients (15.5%). All 18 HAV isolates were genotyped as IA, all 9 HCV isolates were genotyped as 1b, and all 32 HDV isolates were classified into genotype I. The distribution of HBV genotypes among the 67 HBV isolates was A (1.5%, n = 1) and D (98.5%, n = 66). The present study indicates that de novo infections of HAV, HBV, HCV, and HDV are prevalent among young adults in Mongolia. Copyright 2006 Wiley-Liss, Inc.

Full Text Available Congenital hepatic fibrosis is characterized by a ductal plate malformation with duct-like structures and fibrosis. It manifests clinically with portal hypertension and may be associated with multiple congenital defects. We present the case of a 16-year-old male with splenomegaly, leukopenia and thrombocytopenia, esophageal varices, and a histopathological diagnosis of congenital hepatic fibrosis. He exhibits "café au lait' spots and "Lisch' nodules, with a diagnosis of von Recklinghausen's disease. Congenital hepatic fibrosis belongs to the so-called fibropolycystic diseases, in which there is a disordered interaction between cells and the extracellular matrix. Von Recklinghausen's disease affects tissues derived from the neural crest and its diagnosis is based on clinical criteria. It is associated with multiple diseases. We describe its association with congenital hepatic fibrosis for the first time.La fibrosis hepática congénita se origina como consecuencia de una malformación de la placa ductal con estructuras tipo ductales acompañadas de fibrosis. Se manifiesta con hipertensión portal y puede asociarse a múltiples defectos congénitos. Presentamos un varón de 16 años con esplenomegalia, leuco- y plaquetopenia, varices esofágicas y diagnóstico histopatológico de fibrosis hepática congénita. La exploración física mostraba la existencia de manchas de "café con leche' y nódulos de "Lisch' con diagnóstico de enfermedad de von Recklinghausen. La fibrosis hepática congénita forma parte de las enfermedades fibropoliquísticas donde existiría una alteración en la interacción entre las células y la matriz extracelular. La enfermedad de von Recklinghausen afecta a los tejidos derivados de la cresta neural y su diagnóstico se basa en criterios clínicos. Se asocia a múltiples patologías. Presentamos por primera vez su asociación con fibrosis hepática congénita.

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...

To assess retrospectively the cause of hepatic failure related to hepatic arterial embolization (HAE) for hemostasis after pancreaticoduodenectomy or hepatic lobectomy. Between June 1993 and March 2006, Twenty HAEs in 17 patients (15 men, two women; mean age, 64 years) were performed. Angiographic findings, including portal vein stenosis, collateral arterial pathways after HAE, and the difference of embolic materials, were recorded. The morbidity (hepatic failure and abscess) and mortality were detailed according to collateral arterial pathways, portal vein stenosis, and embolic material used. Bleeding was controlled in all patients, although two patients required repeat embolization. Hepatic failure (n = 8) and abscess (n = 2) arose in nine of 20 HAEs. Death occurred after six of eight HAEs complicated by hepatic failure. The morbidity and mortality rates of HAE were 45% and 30%, respectively. Hepatic complication was eight times more likely to occur (P = .005) in cases with no hepatic collaterals involving hepatic, replaced, or accessory hepatic arteries. Death was observed only in the cases without hepatic collaterals (P = .011). The correlation between the embolization outcome and the presence of portal vein stenosis or the difference of embolic materials was not significant (P > .61). HAE can be used to successfully control bleeding secondary to hepatic arterial rupture. In the absence of hepatic collaterals, collateral circulation distal to the occlusion from nonhepatic sources may be inadequate and lead to hepatic failure after HAE. Copyright © 2011 SIR.

A small solitary non-parasitic hepatic cyst causing an intra-hepatic bile duct stricture: a case report

Directory of Open Access Journals (Sweden)

2010-08-01

Full Text Available Abstract Introduction We report an unusual presentation of a small hepatic cyst causing cholangitis. Case presentation A 70-year-old Asian man was hospitalized for aggravated chronic pain in the right upper portion of his abdomen. Fever developed after admission. Laboratory tests revealed elevated hepatobiliary enzymes, inflammatory markers and carbohydrate antigen 19-9 without hyperbilirubinemia. Ultrasound and computed tomography demonstrated dilatation of the left intra-hepatic bile ducts. Endoscopic retrograde cholangiopancreatography showed that the right intra-hepatic bile ducts were normally filled with contrast medium, but the left intra-hepatic bile ducts were not seen in the confluence. A left hepatectomy was performed because a hidden malignancy could not be excluded. The surgical findings showed no tumor around the bile duct but rather a 2 cm cyst in segment four of Couinaud's category of the liver around the hilum. The pathology report was a solitary non-parasitic hepatic cyst compressing the bile duct. Conclusion A very small solitary hepatic cyst might cause hepatic duct stricture if it is located near the hepatic hilum, and should be considered in the differential diagnosis of a hepatic duct stricture.

Determination of hepatic fractional clearance of radioactive gold colloids for a measure of effective hepatic blood flow

International Nuclear Information System (INIS)

Fujii, Masahiro

1979-01-01

For a measure of effective blood flow, a hepatic fractional clearance of 198 Au-colloids was determined, which was obtained from the disappearance rate multiplied by the fraction of injected dose taken up by the liver. The hepatic uptake was determined with a gamma camera. The counts over the liver was corrected for body weight and height. The method was considered sufficiently simple for routine use. 198 Au-colloids were obtained from Dainabot Lab. and CIS. The former gave 64% higher values of disappearance rate than the latter, without any change in the organ distribution. A quality control tests were applied over a six-year period to the disappearance rates. Reproducibility within 95 to confidence limits was found for both groups. In 28 normal control subjects, hepatic fractional clearance of the colloids from Dainabot Lab. was 18.5 +- 3.4%/min. In patients with progressed hepatic disease, both hepatic fractional clearance and final hepatic uptake were decreased, showing that the determination of hepatic uptake is necessary in measuring effective hepatic blood flow by the colloidal clearance method. The influence of splenic uptake is discussed in relation to hepatic blood flow measurement. (author)

Human hepatic lipase overexpression in mice induces hepatic steatosis and obesity through promoting hepatic lipogenesis and white adipose tissue lipolysis and fatty acid uptake.

Directory of Open Access Journals (Sweden)

Lídia Cedó

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.

Hepatic encephalopathy describes the array of neurological alterations that occur during acute liver failure or chronic liver injury. While key players in the pathogenesis of hepatic encephalopathy, such as increases in brain ammonia, alterations in neurosteroid levels, and neuroinflammation, have been identified, there is still a paucity in our knowledge of the precise pathogenic mechanism. This review gives a brief overview of our understanding of the pathogenesis of hepatic encephalopathy and then summarizes the significant recent advances made in clinical and basic research contributing to our understanding, diagnosis, and possible treatment of hepatic encephalopathy. A literature search using the PubMed database was conducted in May 2017 using “hepatic encephalopathy” as a keyword, and selected manuscripts were limited to those research articles published since May 2014. While the authors acknowledge that many significant advances have been made in the understanding of hepatic encephalopathy prior to May 2014, we have limited the scope of this review to the previous three years only.

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

To determine the feasibility and safety of establishing a porcine hepatic cirrhosis and portal hypertension model by hepatic arterial perfusion with 80% alcohol. Twenty-one healthy Guizhou miniature pigs were randomly divided into three experimental groups and three control groups. The pigs in the three experimental groups were subjected to hepatic arterial perfusion with 7, 12 and 17 mL of 80% alcohol, respectively, while those in the three control groups underwent hepatic arterial perfusion with 7, 12 and 17 mL of saline, respectively. Hepatic arteriography and direct portal phlebography were performed on all animals before and after perfusion, and the portal venous pressure and diameter were measured before perfusion, immediately after perfusion, and at 2, 4 and 6 wk after perfusion. The following procedures were performed at different time points: routine blood sampling, blood biochemistry, blood coagulation and blood ammonia tests before surgery, and at 2, 4 and 6 wk after surgery; hepatic biopsy before surgery, within 6 h after surgery, and at 1, 2, 3, 4 and 5 wk after surgery; abdominal enhanced computed tomography examination before surgery and at 6 wk after surgery; autopsy and multi-point sampling of various liver lobes for histological examination at 6 wk after surgery. In experimental group 1, different degrees of hepatic fibrosis were observed, and one pig developed hepatic cirrhosis. In experimental group 2, there were cases of hepatic cirrhosis, different degrees of increased portal venous pressure, and intrahepatic portal venous bypass, but neither extrahepatic portal-systemic bypass circulation nor death occurred. In experimental group 3, two animals died and three animals developed hepatic cirrhosis, and different degrees of increased portal venous pressure and intrahepatic portal venous bypass were also observed, but there was no extrahepatic portal-systemic bypass circulation.

1980-01-01

The liver scintigraphies of five patients with fulminant hepatitis were examined. Scintiphotos using sup(99m)Tc-phytate were taken within two weeks after the onset. Scintiphotos of 12 normal subjects, 11 cases with acute hepatitis, 17 cases with liver cirrhosis were served as control. Their scintiphotos showed reduction of the size, well-maintained uptake, mostly homogenous RI distribution, and no left lobe enlargement, which could differentiate them from the chronic liver dysfunction. In one of the cases chronological changes in liver scintigraphy were observed. The size of the liver was reduced progressively until the 16th day and re-enlarged at the 30th day and thereafter. Three indices [S/W, (R + L)/W, and L/R] were calculated. S: area of liver, R or L: longitudinal length of the right or left lobe, W: body width. Relative size of the liver expressed by S/W or (R + L)/W showed significant reduction in fulminant hepatitis compared with acute hepatitis. However, they were not different significantly from those of normal subjects. Except for liver cirrhosis, L/R (left lobe swelling index) did not show significant differences among fulminant hepatitis, normal subjects, and acute hepatitis. These indices were also useful in follow-up study of the liver scintigraphy. The liver scintigraphy in the early phase of fulminant hepatitis seems to reflect the degree of massive hepatic necrosis. It is also useful to differentiate chronic hepatic failure. Apparant reduction in scintigraphical liver size seems to suggest poor prognosis, however, it should also kept in mind that the size of the liver in this condition might change quite rapidly and greatly.

Valtolina, Chiara; Favier, Robert P

2017-05-01

Feline hepatic lipidosis (FHL) is a common and potentially fatal liver disorder. Although the pathophysiologic mechanisms of FHL remain elusive, there is an imbalance between the influx of fatty acids from peripheral fat stores into the liver, de novo liposynthesis, and the rate of hepatic oxidation and dispersal of hepatic TAG via excretion of very-low density lipoproteins. The diagnosis of FHL is based on anamnestic, clinical, and clinicopathologic findings, associated with diagnostic imaging of the liver, and cytology, or histological examination of liver biopsies. Fluid therapy, electrolyte correction and adequate early nutrition are essential components of the therapy for FHL. Copyright © 2016 Elsevier Inc. All rights reserved.

To review the nonoperative and operative management of blunt hepatic injury in the adult trauma population. Although liver injury scale does not predict need for surgical intervention, a high-grade complex liver injury should alert the physician to a patient at increased risk of hepatic complications following nonoperative management. Blunt hepatic injury remains a frequent intraabdominal injury in the adult trauma population. The management of blunt hepatic injury has undergone a major paradigm shift from mandatory operative exploration to nonoperative management. Hemodynamic instability with a positive focused abdominal sonography for trauma and peritonitis are indications for emergent operative intervention. Although surgical intervention for blunt hepatic trauma is not as common as in years past, it is imperative that the current trauma surgeon be familiar with the surgical skill set to manage complex hepatic injuries. This study represents a review of both nonoperative and operative management of blunt hepatic injury.

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.

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

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)

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.

2011-01-01

Full Text Available El sitio arqueológico Cancuén se destaca en el área maya del Clásico Tardío por su localización en el río de la Pasión, entre las Tierras Altas y las Tierras Bajas de Guatemala; desde allí la ciudad controló parte del flujo de bienes entre ambas áreas. Esto pudo comprobarse a través de la excavación de un taller de manufactura de artefactos de jade, cuya existencia fue un hecho único en las ciudades de Tierras Bajas. El estudio de la cerámica de este sitio presenta un doble reto: primero, ubicar Cancuén culturalmente, revelando una mezcla de influencias cerámicas procedentes de varias regiones vecinas. Una presentación sintética de la tipología permite vislumbrar la complejidad de las redes de intercambio y producción local de las vasijas. El segundo reto es el de establecer una cronología fina para los apenas 150 años de duración de la ocupación del sitio. La confrontación de la tipología cerámica con los datos epigráficos y los eventos políticos locales, permite establecer una secuencia cronológica completa, una de las primeras para esta zona fronteriza entre Tierras Bajas y Tierras Altas.Cancuén archaeological site is relevant within the Late Classic Maya context because of its geographical position on Pasión River, between Lowlands and Highlands of Guatemala, from where it controlled one of the greatest trade route between both areas. This has been evidenced by the excavation of a workshop where jade artifacts where produced, which is a unique discovery in Maya Lowlands. The analysis of ceramics in Cancuén represents a double challenge: first, it may define Cancuén's culturally, highlighting a mix of ceramic influences coming from different neighboring regions. A rapid presentation of the typology shows a quite complex panorama for exchange and local production of vessels. The second challenge is about establishing a fine chronology for the only 150 years of occupation. By confronting ceramic data with

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)

Understanding of the anatomy of the hepatic vein is important in manipulation for transplantation of the liver, hepatectomy and the treatment of hepatic trauma with avulsion of the hepatic vein. Demonstrated of the inferior right hepatic vein (IRHV) is also important; in some cases of hepatocellular carcinoma, thrombus can be seen in the IRHV; in primary Budd-Chiari syndrome, the IRHV is main draining vein; during hepatectomy, the postero-inferior segment of the right lobe and draining IRHV can be preserved. For some 10 months ultrasound examination was done in a total of 124 patients with normal liver function with special emphasis on the hepatic vein, their branches, and the IRHV, and analysed in terms of branching pattern and relative size of the hepatic vein and the detection rate of the IRHV.

2009-01-01

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: 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.

Changes in waveform on hepatic venous doppler in patients with chronic hepatic B: Correlation with histologic findings

Ko, Joon Seok; Kim, Hak Soo; Chung, Dong Hae

2001-01-01

To evaluate changes of the waveform of the hepatic vein on doppler ultrasound (US) in patients with chronic hepatic B and to correlate them with histologic findings. Thirty three patients with chronic hepatic B were prospectively examined with doppler US, and liver biopsy was done at the same time. The right hepatic vein was examined on doppler US, and a liver biopsy was performed in the right lobe of the liver. Doppler waveform was considered abnormal if it showed either reduction in the amplitude of phasic oscillation without the reversed flow phase or the presence of completely flow. Specimens obtained from the biopsy were classified according to the predetermined histologic scoring criteria. It was technically possible to performed Doppler US of the right hepatic vein and liver biopsy simultaneously in all thirty three patients. Waveforms of the right hepatic vein were abnormal in fourteen (42.4%), biphasic in 12 (36.4%) and flat in two (6.0%) patients. Only the steatosis exhibited statistically significant correlation between changes of doppler waveform (p,0.05) of the normal and abnormal groups. Doppler US patterns of the hepatic vein in chronic hepatitis B were different from those of the normal group. The abnormal flow pattern on hepatic venous doppler appeared to be mainly influenced by the intrahepatic fat deposition rather than the degree of fibrosis.

Full Text Available The progression of chronic liver disease differs by etiology. The aim of this study was to elucidate the difference in disease progression between chronic hepatitis C (CHC and nonalcoholic fatty liver disease (NAFLD by means of fibrosis markers, liver function, and hepatic tissue blood flow (TBF. Xenon computed tomography (Xe-CT was performed in 139 patients with NAFLD and 152 patients with CHC (including liver cirrhosis (LC. The cutoff values for fibrosis markers were compared between NAFLD and CHC, and correlations between hepatic TBF and liver function tests were examined at each fibrosis stage. The cutoff values for detection of the advanced fibrosis stage were lower in NAFLD than in CHC. Although portal venous TBF (PVTBF correlated with liver function tests, PVTBF in initial LC caused by nonalcoholic steatohepatitis (NASH-LC was significantly lower than that in hepatitis C virus (C-LC (p = 0.014. Conversely, the liver function tests in NASH-LC were higher than those in C-LC (p < 0.05. It is important to recognize the difference between NAFLD and CHC. We concluded that changes in hepatic blood flow occurred during the earliest stage of hepatic fibrosis in patients with NAFLD; therefore, patients with NAFLD need to be followed carefully.

The experimental study is aimed at achieving the effect of hepatic tumor and tumor-bearing lobar or segmental resection by using combined transcatheter hepatic arterial embolization and retrograde hepatic venous embolization (THAE-RHVE) in experimental study. THAE-RHVE was carried out in 8 mongrel dogs. Hepatic arterial embolization was performed by injecting lipiodol followed by gelatin sponge particles, following complete occlusion of the hepatic vein with balloon catheter. Retrograde hepatic venous embolization (RHVE) was then performed by injecting a mixture of absolute ethanol and meglumini diatrizoatis (MD) via the inflated balloon catheter. Ethanol and MD were combined with a ratio of 1:1. RHVE alone was performed in 4 dogs as control. The animals were followed up for 1∼8 weeks with liver function test, CT, gross and microscopic examinations. There was no technical failure or procedural complications. Transient elevation of AST and ALT levels was seen immediately in both groups after the procedure. Follow-up CT after 3 weeks showed dense lipiodol accumulation in the embolized lobe or segment and the corresponding portal branches in the THAE-RHVE animals. At 1 week after THAE-RHVE, complete coagulation necrosis was seen at histologic examination in the embolized lobe. The hepatic vein and portal branches of the embolized area had thickened walls and were filled with thrombus. At 2 weeks, granulomatous tissue and inflammatory cell infiltration surrounding the necrotic area could be seen. At 4∼8 weeks, marked atrophy of the embolized lobe was found, and the necrotic area was progressively reducing in size and being replaced by fibrosis. In the control group, incomplete segmental coagulated necrosis was seen and the necrosis area wa smaller than that of THAE-REVE. Hepatic lobectomy or segmentectomy can be achieved with THAE-RHVE. This new method is safe and easy, and may be useful in the treatment of HCC

Hepatitis B viral factors and treatment responses in chronic hepatitis B

Directory of Open Access Journals (Sweden)

Chih-Lin Lin

2013-06-01

Full Text Available Baseline and on-treatment hepatitis B viral factors are reported to affect treatment responses. A lower baseline hepatitis B virus (HBV DNA level is a strong predictor of the response to antiviral therapy. HBV genotype A/B patients have better responses to interferon-based therapy than those with genotypes C/D. Regarding the association of HBV mutants with responses to antiviral therapy, current evidence is limited. On-treatment viral suppression is the most important predictor of response to nucleoside analogs. On-treatment hepatitis B surface antigen decline is significantly associated with response to pegylated interferon. In the future, individualized therapy should be based on treatment efficacy, adverse effects, baseline and on-treatment predictors of antiviral therapy.

Comparative Pathology of Hepatitis A Virus and Hepatitis E Virus Infection.

Cullen, John M; Lemon, Stanley M

2018-04-30

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.

Fine-needle aspirate cytology suggesting hepatic lipidosis in four cats with infiltrative hepatic disease.

Science.gov (United States)

Willard, M D; Weeks, B R; Johnson, M

1999-12-01

Four cats are reported in which cytology smears obtained by ultrasound-guided fine needle aspiration of the liver were interpreted as indicative of hepatic lipidosis. However, histopathology of hepatic tissue samples obtained with Tru-Cut-like needles or wedge biopsy revealed that the cats had inflammatory or neoplastic hepatic disease causing their clinical signs. Fine needle aspiration and cytology may not detect infiltrative lesions, particularly those that are nodular, multifocal, or localised around the portal regions. Fine needle aspirate cytology is a useful diagnostic procedure with many advantages, but care must be taken to avoid diagnosing hepatic lipidosis as the cause of illness when an infiltrative lesion is responsible.

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

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 detection of diagnostic autoantibodies such as antinuclear antibodies (ANA), anti-smooth muscle antibodies (SMA), anti-liver/kidney microsomal type 1 (anti-LKM1), anti-liver cytosol type 1 (anti-LC1) and anti-soluble liver antigen (anti-SLA) is historically associated with the diagnosis of autoimmune hepatitis. When autoimmune hepatitis is suspected, the detection of one or any combination of diagnostic autoantibodies, by indirect immunofluorescence or immuno-enzymatic techniques with recombinant antigens, is a pivotal step to reach a diagnostic score of probable or definite autoimmune hepatitis. Diagnostic autoantibodies (ANA, SMA, anti-LKM1, anti-LC1, anti-SLA) are a cornerstone in the diagnosis of autoimmune hepatitis. Other ancillary autoantibodies, associated with peculiar clinical correlations, appear to be assay-dependent and institution-specific, and validation studies are needed. © 2015 S. Karger AG, Basel.

2006-01-01

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)

Hepatic resection and regeneration. Past and present

International Nuclear Information System (INIS)

Hatsuse, Kazuo

2007-01-01

Hepatic surgery has been performed on condition that the liver regenerates after hepatic resection, and the development of liver anatomy due to Glisson, Rex, and Couinaud has thrown light on hepatic surgery Understanding of feeding and drainage vessels became feasible for systemic hepatic resection; however, it seems to have been the most important problem to control the bleeding during hepatic resection. New types of devices such as cavitron ultrasonic surgical aspirator (CUSA) and Microwave coagulation were exploited to control blood loss during hepatic surgery. Pringle maneuver for exclusion feeding vessels of the liver and the decrease of central venous pressure during anesthesia enabled further decrease of blood loss. Nowadays, 3D-CT imaging may depict feeding and drainage vessels in relation to liver mass, and surgeons can simulate hepatic surgery in virtual reality before surgery, allowing hepatectomy to be performed without blood transfusion. Thus, hepatic resection has been a safe procedure, but there's been a significant research on how much of the liver can be resected without hepatic failure. A prediction scoring system based on ICGR15, resection rates, and age is mostly reliable in some criteria. Even if hepatectomy is performed with a good prediction score, the massive bleeding and associated infection may induce postoperative hepatic failure, while the criteria of postoperative hepatic failure have not yet established. Hepatic failure is supposed to be induced by the apoptosis of mature hepatocytes and necrosis originated from microcirculation disturbance of the liver. Prostaglandin E1 for the improvement of microcirculation, steroid for the inhibition of cytokines inducing apoptosis, and blood purification to exclude cytokines have been tried separately or concomitantly. New therapeutic approaches, especially hepatic regeneration from the stem cell, are expected. (author)

Rosen, Elissa; Bakshi, Neeru; Watters, Ashlie; Rosen, Hugo R; Mehler, Philip S

2017-11-01

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.

The ''Dimple sign'' has been coined by Baltaxe et al. in 1974 and was said to be useful angiographic sign of avascular tumor. Similar dimple can be seen in the margin of the liver on CT examination of the hepatic tumors. We called this hepatic dimple sign and its clinical usefulness on CT examination was studied with 133 cases of hepatic tumors. Among 133 cases, there were 68 cases of hepatocellular carcinoma, 57 cases of metastatic liver tumor, 5 cases of hemangioma of the liver and 3 cases of hepatoblastoma. Hepatic dimple sign was recognized on 2 cases of metastatic liver tumor, 1 case of hemangioma, and 1 case of carcinoma of the gallbladder with hepatic infiltration. Cases experienced in the affiliated hospitals were also studied. A case of hepatocellular carcinoma and a case of metastatic liver tumor were evaluated. These tumors were relativly large measuring over 5cm in the greatest diameter and low density areas were apparent on plain CT. Therefore, dimples in the hepatic margin seen in CT scan did not contribute to the diagnostic accuracy of the liver tumor in these cases. (author)

The course and outcome of acute viral hepatitis in liver transplanted patients with hepatitis C recurrence are unknown. Here we describe a patient who presented with acute hepatitis B infection while on treatment with peg-interferon and ribavirin for hepatitis C recurrence after liver transplantation. A nucleoside analogue was added (entecavir) and the patient cleared hepatitis C virus (HCV) infection and seroconverted to anti-HBs. In this case, the acute hepatitis B virus (HBV) infection might have contributed to the clearance of HCV, the concomitant immunosuppression might have lead to the slow clearance of HBV infection, and the combined antiviral therapy has helped in the resolution of both infections. Hepatitis B vaccination should be recommended in susceptible patients waiting for liver transplantation.

Tajima, T.; Yoshimitsu, K.; Irie, H.; Nishie, A.; Hirakawa, M.; Ishigami, K.; Ushijima, Y.; Okamoto, D.; Honda, H.

2009-01-01

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

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.

Letoublon, Christian; Morra, Irene; Chen, Yao; Monnin, Valerie; Voirin, David; Arvieux, Catherine

2011-05-01

The objective was to clarify the role of hepatic arterial embolization (AE) in the management of blunt hepatic trauma. Retrospective observational study of 183 patients with blunt hepatic trauma admitted to a trauma referral center over a 9-year period. The charts of 29 patients (16%) who underwent hepatic angiography were reviewed for demographics, injury specific data, management strategy, angiographic indication, efficacy and complications of embolization, and outcome. AE was performed in 23 (79%) of the patients requiring angiography. Thirteen patients managed conservatively underwent emergency embolization after preliminary computed tomography scan. Six had postoperative embolization after damage control laparotomy and four had delayed embolization. Arterial bleeding was controlled in all the cases. Sixteen patients (70%) had one or more liver-related complications; temporary biliary leak (n=11), intra-abdominal hypertension (n=14), inflammatory peritonitis (n=3), hepatic necrosis (n=3), gallbladder infarction (n=2), and compressive subcapsular hematoma (n=1). Unrecognized hepatic necrosis could have contributed to the late posttraumatic death of one patient. AE is a key element in modern management of high-grade liver injuries. Two principal indications exist in the acute postinjury phase: primary hemostatic control in hemodynamically stable or stabilized patients with radiologic computed tomography evidence of active arterial bleeding and adjunctive hemostatic control in patients with uncontrolled suspected arterial bleeding despite emergency laparotomy. Successful management of injuries of grade III upward often entails a combined angiographic and surgical approach. Awareness of the ischemic complications due to angioembolization is important.

Twenty-nine patients with hepatic artery occlusion were treated with additional hepatic infusion or embolization through extrahepatic collaterals. Seventeen courses of hepatic infusion were performed in 13 patients through the inferior pancreaticoduodenal artery, left gastric artery, or right gastric artery. Twenty-five hepatic embolization procedures were performed in 16 patients through the right and left phrenic arteries, left and right gastric arteries, pancreaticoduodenal artery, gastroduodenal artery, or omentoepiploic artery. In one patient gastric ulcers developed following left gastric artery infusion. No complication related to the embolization procedure was observed in the embolization group. The extrahepatic collaterals are important alternative routes for continuous transcatheter management of hepatic neoplasms following hepatic artery occlusion.

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.

Hepatic atrophy has been recognized as a complication of hepatic and biliary disease but we have often found it in follow up CT after transcatheter arterial embolization (TACE). The purpose of this study is to evaluate the characteristics of hepatic atrophy after TACE. Of 53 patients who had TACE. We evaluated the relationship between the incidence of hepatic atrophy and the number of TACE, and also evaluated the average number of TACE in patients with hepatic atrophy. Of 20 patients who had received more than average number of TACE for development of hepatic atrophy (2 times with portal vein obstruction, 2.7 times without portal vein obstruction in this study), we evaluated the relationship between the lipiodol uptake pattern of tumor and the incidence of hepatic atrophy. There were 8 cases of hepatic atrophy (3 with portal vein obstruction, 5 without portal vein obstruction), average number for development of hepatic atrophy were 2.5 times. As the number of TACE were increased, the incidence of hepatic atrophy were also increased. Of 20 patients who received more than average number of TACE for development of hepatic atrophy, we noted 6 cases of hepatic atrophy in 11 patients with dense homogenous lipiodol uptake pattern of tumor and noted only 1 case of hepatic atrophy in 9 patient with inhomogenous lipiodol uptake pattern. Hepatic atrophy was one of the CT findings after TACE even without portal vein obstruction. Average number of TACE was 2.5 times and risk factors for development of hepatic atrophy were portal vein obstruction, increased number of TACE, and dense homogenous lipiodol uptake pattern of tumor

Hepatitis E shares some similarities with hepatitis A, notably the mode of transmission and the absence of chronic course. However, a few important differences have been noted, including a higher mortality rate and a high fatality rate in pregnant women. Hepatitis E is very common in developing countries and should be suspected more often in individuals with gastrointestinal complaints returning from endemic areas.

Hepatic drug clearance following traumatic injury.

Science.gov (United States)

Slaughter, R L; Hassett, J M

1985-11-01

Trauma is a complex disease state associated with physiologic changes that have the potential to alter hepatic drug clearance mechanisms. These responses include alterations in hepatic blood flow, reduction in hepatic microsomal activity, reduction in hepatic excretion processes, and changes in protein binding. Hepatic blood flow is influenced by sympathomimetic activity. Both animal and human studies demonstrate an initial reduction and subsequent increase in hepatic blood flow, which coincides with an observed increase and subsequent return to normal in serum catecholamine concentrations. Unfortunately, there are no human studies that address the importance these findings may have to the clearance processes of high intrinsic clearance compounds. Animal studies of trauma indicate that hepatic microsomal activity is depressed during the post-traumatic period. Reduction in the hepatic clearance of antipyrine, a model low intrinsic compound, has also been demonstrated in animal models of trauma. In addition to these effects, hepatic excretion of substances such as indocyanine green and bilirubin have been demonstrated to be impaired in both traumatized animals and humans. Finally, substantial increases in the serum concentration of the binding protein alpha 1-acid glycoprotein occur in trauma patients. This has been reported to be associated with subsequent decreases in the free fraction of lidocaine and quinidine. In addition to changing serum drug concentration/response relationships, the pharmacokinetic behavior of drugs bound to alpha 1-acid glycoprotein should also change. Preliminary observations in our laboratory in a dog model of surgically-induced trauma have shown a reduction in the total clearance of lidocaine and reduction in free lidocaine concentration.(ABSTRACT TRUNCATED AT 250 WORDS)

[Hepatitis: a longstanding companion in human history].

2012-03-01

Hepatitis has gone along with human history since its origins, due to its prompt identifiability linked to jaundice as a symptom. Written evidence of outbreaks of epidemic jaundice can be tracked back a few millenniums before Christ. Unavoidable confusion arises due to the overlap of different sources possibly linked to different aetiologies, identified over time as epidemic jaundice (HAV or HEV hepatitis?) and serum hepatitis (HBV or HCV hepatitis?). The journey that brought to recognize viruses as the main cause of jaundice was long and started midway during the last century, when the infectious hypothesis, which had taken place step by step, was finally confirmed by epidemiological investigations of an outbreak occurring in the US army in 1942, after a yellow fever immunization campaign. Further research identified two clinically different types of hepatitis, called for the first time hepatitis A and hepatitis B.

Tan, Ker-Kan; Bang, Shieh-Ling; Vijayan, Appasamy; Chiu, Ming-Terk

2009-09-01

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.

Doppler waveform of hepatic vein in patients with chronic hepatitis B; Correlation with histologic grade and stage

1999-01-01

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.

Hepatic amebiasis

Salles José Maria

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. In patients with large abscesses, showing signs of imminent rupture, and especially those who do not respond to medical treatment, a

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. In patients with large abscesses, showing signs of imminent rupture, and especially those who do not respond to medical treatment, a

Hepatic encephalopathy is considered a contraindication to hepatic artery embolization. We describe a patient with a well-differentiated neuroendocrine tumor metastatic to the liver with refractory hepatic encephalopathy and normal liver function tests. The encephalopathy was refractory to standard medical therapy with lactulose. The patient's mental status returned to baseline after three hepatic artery embolization procedures. Arteriography and ultrasound imaging before and after embolization suggest that the encephalopathy was due to arterioportal shunting causing hepatofugal portal venous flow and portosystemic shunting. In patients with a primary or metastatic well-differentiated neuroendocrine tumor whose refractory hepatic encephalopathy is due to portosystemic shunting (rather than global hepatic dysfunction secondary to tumor burden), hepatic artery embolization can be performed safely and effectively.

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.

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.

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.

The sera of 64 patients with acute viral hepatitis which were previously HbsAG negative by rPHA were tested by RIA methods for the presence of HBsAG and anti-HBc, by EIA method for HBc and anti-HBc and also by RIA method for the presence of IgM antibodies against hepatitis A virus. The pairs of sera were tested also for the presence of antibodies against cytomegalovirus and EB viruses. Of the total of 64 patients, markers of fresh HB viral infection were proved in 5 patients, sera positive to IgM antibodies to hepatitis A virus were found in 51 and no positive tests to any of the tested viruses were found in 8. The authors consider that they belonged to "non-A, non-B" viral hepatitis.

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

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.

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 progression of chronic liver disease differs by etiology. The aim of this study was to elucidate the difference in disease progression between chronic hepatitis C (CHC) and nonalcoholic fatty liver disease (NAFLD) by means of fibrosis markers, liver function, and hepatic tissue blood flow (TBF). Xenon computed tomography (Xe-CT) was performed in 139 patients with NAFLD and 152 patients with CHC (including liver cirrhosis (LC)). The cutoff values for fibrosis markers were compared between NAFLD and CHC, and correlations between hepatic TBF and liver function tests were examined at each fibrosis stage. The cutoff values for detection of the advanced fibrosis stage were lower in NAFLD than in CHC. Although portal venous TBF (PVTBF) correlated with liver function tests, PVTBF in initial LC caused by nonalcoholic steatohepatitis (NASH-LC) was significantly lower than that in hepatitis C virus (C-LC) (p = 0.014). Conversely, the liver function tests in NASH-LC were higher than those in C-LC (p blood flow occurred during the earliest stage of hepatic fibrosis in patients with NAFLD; therefore, patients with NAFLD need to be followed carefully.

Genetic determinants of hepatic steatosis in man

Hooper, Amanda J.; Adams, Leon A.; Burnett, John R.

2011-01-01

Hepatic steatosis is one of the most common liver disorders in the general population. The main cause of hepatic steatosis is nonalcoholic fatty liver disease (NAFLD), representing the hepatic component of the metabolic syndrome, which is characterized by type 2 diabetes, obesity, and dyslipidemia. Insulin resistance and excess adiposity are considered to play key roles in the pathogenesis of NAFLD. Although the risk factors for NAFLD are well established, the genetic basis of hepatic steatosis is largely unknown. Here we review recent progress on genomic variants and their association with hepatic steatosis and discuss the potential impact of these genetic studies on clinical practice. Identifying the genetic determinants of hepatic steatosis will lead to a better understanding of the pathogenesis and progression of NAFLD. PMID:21245030

Four siblings with hepatic fibrosis are described. The liver damage in these patients was secondary to chronic ingestion of massive doses of vitamin A for congenital ichthyosis. Although the extrahepatic manifestations were helpful in the diagnosis of hypervitaminosis A, the distinctive features of hepatic histopathology were confirmatory. The plasma concentrations of vitamin A and retinol-binding protein were misleading. The recovery from the liver damage in these patients was slow despite a complete withdrawal of the vitamin A intake. These cases show the importance of hepatic vitamin A assessment in the diagnosis of hepatic fibrosis.

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)

Autoimmune hepatitis is chronic liver disease with two subtypes, type 1 with anti nuclear or smooth muscle antibodies and type 2 with LKM1 or LC1 antibodies, and both with hypergammaglobulinemia and typical histology. Prevalence of AIH is between 10 to 17 per 100000 in Europe. Up to 20-40 % of cases present with acute hepatitis. Budesonide can be used as a first line induction therapy in non-cirrhotic patients, and tiopurines, mercaptopurine or mycophenolic acid as maintenance therapies. Patients not responding to conventional therapy can be treated with ciclosporin, tacrolimus or rituximab or finally with liver transplantation.

There are discrepant data on whether men or women have a higher risk for hepatic steatosis. To examine the influence of gender on hepatic adiposity in teenagers and young adults. We measured subcutaneous abdominal fat (SAF), intra-abdominal fat (IAF) and hepatic tissue density (a surrogate measure of hepatic fat) using CT in 505 healthy teenagers and young adults (254 males, 251 females; ages 15-22.9 years). Overall, compared to men, women had higher values of SAF (P < 0.0001) but similar measures of IAF and liver tissue density (P = 0.09 and 0.92, respectively). However, when compared to overweight/obese men, overweight/obese women had strikingly similar IAF values (P = 0.85) but lower hepatic fat (P = 0.009). Multiple regression analyses indicated that, after adjusting for age and SAF, IAF independently predicted hepatic density in males (P < 0.0001) but not in females (P = 0.36). Hepatic fat increased with body mass in males from lean to overweight and obese (P < 0.0001) but not in females (P > 0.05). When compared to overweight and obese young women, overweight and obese young men are at greater risk for hepatic steatosis, independent of IAF. (orig.)

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.

Prevention of hepatitis A virus (HAV) and hepatitis B virus (HBV) infection in patients with chronic hepatitis C (CHC) through vaccination is endorsed by all major professional societies. This study was conducted to determine adherence to the recently adopted physician performance measure on HAV and HBV vaccination. This was a retrospective study. Hepatitis A and B serology data and immunization records between 2000 and 2007 from CHC patients with detectable hepatitis C virus (HCV) RNA were analyzed. A total of 2,968 CHC patients were included in the study. Of these, 2,143 patients (72%) were tested for susceptibility to HAV, of which 53% had immunity. Of the non-immune patients, 746 (74%) were vaccinated as well as an additional 218 without prior testing. For HBV, 2,303 patients (78%) were tested for immunity and 782 (34%) were immune. Of the susceptible patients, 1,086 (71%) were vaccinated as well as an additional 197 patients without prior testing. The overall vaccination performance measure adherence rate was 71% for HAV, 70% for HBV, and 62% for both HAV and HBV. Random review of 176 charts found the major reasons for non-adherence were missed opportunity (41%), change of health care system (31%), and documented vaccination outside our health care system (22%). Our study found a high and improved adherence to the recommendations, but missed opportunity was still the main reason of non-adherence. This study also supported the strategy of selective vaccination in the veteran population.

Cuidado centrado na família no contexto da criança com deficiência e sua família: uma análise reflexiva

Full Text Available Es una reflexión teórico-filosófica sobre la perspectiva del Cuidado Centrado en la Familia con la práctica del equipo de salud en el cuidado al niño con discapacidad y su familia. El nacimiento de un niño con discapacidad provoca una crisis que perjudica toda la familia, con problemas para su identidad, estructura y funcionamiento. La familia se muestra sin preparación para enfrentar ese nuevo modo de verse familia, pues el hijo representa una experiencia traumática que puede alterar el estado emocional entero de los miembros. Las presuposiciones del Cuidado Centrado en la Familia pueden fortalecer a la familia, estimular su potencial y promover el fortalecimiento familiar en su trayectoria con el hijo. Aunque con las presuposiciones del Cuidado Centrado en la Familia se reconozca a la familia como la unidad de cuidado, una laguna se observa entre el conocimiento teórico y de aplicación en la práctica clínica por los profesionales de salud, revelando la necesidad de ampliar los estudios que indiquen caminos hacia la transferencia de conocimientos.

Immune cell-mediated attack on the liver is a defining feature of autoimmune hepatitis and hepatic allograft rejection. Despite an assortment of diagnostic tools, invasive biopsies remain the only method for identifying immune cells in the liver. We evaluated whether PET imaging with radiotracers that quantify immune activation ( 18 F-FDG and 18 F-FAC) and hepatocyte biology ( 18 F-DFA) can visualize and quantify hepatic infiltrating immune cells and hepatocyte inflammation, respectively, in a preclinical model of autoimmune hepatitis. Methods: Mice treated with Concanavalin A (ConA) to induce a model of autoimmune hepatitis or vehicle were imaged with 18 F-FDG, 18 F-FAC, and 18 F-DFA PET. Immunohistochemistry, digital autoradiography, and ex vivo accumulation assays were used to localize areas of altered radiotracer accumulation in the liver. For comparison, mice treated with an adenovirus to induce a viral hepatitis or vehicle were imaged with 18 F-FDG, 18 F-FAC, and 18 F-DFA PET. 18 F-FAC PET was performed on mice treated with ConA, and vehicle or dexamethasone. Biopsy samples of patients suffering from autoimmune hepatitis were immunostained for deoxycytidine kinase (dCK). Results: Hepatic accumulation of 18 F-FDG and 18 F-FAC was 173% and 61% higher, respectively, and hepatic accumulation of 18 F-DFA was 41% lower in a mouse model of autoimmune hepatitis compared to control mice. Increased hepatic 18 F-FDG accumulation was localized to infiltrating leukocytes and inflamed sinusoidal endothelial cells, increased hepatic 18 F-FAC accumulation was concentrated in infiltrating CD4 and CD8 cells, and decreased hepatic 18 F-DFA accumulation was apparent in hepatocytes throughout the liver. In contrast, viral hepatitis increased hepatic 18 F-FDG accumulation by 109% and decreased hepatic 18 F-DFA accumulation by 20% but had no effect on hepatic 18 F-FAC accumulation (non-significant 2% decrease). 18 F-FAC PET provided a non-invasive biomarker of the efficacy of

Objective: To assess the effects of hepatitis B vaccination on the antibody titer in patients with chronic hepatitis C and to compare it with response in normal healthy subjects. Study Design: Interventional study. Place and Duration of Study: Shifa International Hospital, Islamabad, Pakistan, from January 2007 to January 2012. Methodology: Hepatitis vaccination (Heberbiovac-HB 20) was given intramuscularly to the patients of chronic hepatitis C (HCV group) and normal healthy subjects (control group) at 0, 1 and 6 months intervals. Anti-HBs titer was determined after second and third injection to assess the antibody response. Results: There were 46 patients in the HCV group and 45 patients in the control group. Mean age was 40.9 A +- 9.8 years in the HCV group and 33.18 A +- 8.35 years in the control group. Weight was 67.04 A +- 13.5 kg in the HCV group and 71.78 A +- 14.63 kg in the control group. Height was 162.45 A +- 9.06 cm in the HCV group and 167.03 A +- 7.83 cm in the control group. Anti-HBs antibody levels after the second injection were 253.89 A +- 76.76 mlU/mL in the HCV group and 245.81 A +- 72.65 mlU/mL in the control group (p=0.172). After third injection, the antibody levels were slightly higher in both groups. Conclusion: In patients with chronic hepatitis C and normal healthy subjects, Heberbiovac HB in standard dosage gave sero-protective levels in both groups and antibody titers were not significantly different in control and HCV group.

Nonhuman Primate Models of Hepatitis A Virus and Hepatitis E Virus Infections.

Science.gov (United States)

Lanford, Robert E; Walker, Christopher M; Lemon, Stanley M

2018-04-23

Although phylogenetically unrelated, human hepatitis viruses share an exclusive or near exclusive tropism for replication in differentiated hepatocytes. This narrow tissue tropism may contribute to the restriction of the host ranges of these viruses to relatively few host species, mostly nonhuman primates. Nonhuman primate models thus figure prominently in our current understanding of the replication and pathogenesis of these viruses, including the enterically transmitted hepatitis A virus (HAV) and hepatitis E virus (HEV), and have also played major roles in vaccine development. This review draws comparisons of HAV and HEV infection from studies conducted in nonhuman primates, and describes how such studies have contributed to our current understanding of the biology of these viruses.

Viral hepatitis is a serious global public health problem. It is also a common cause of jaundice and gestational complications in pregnant women. Moreover, infected mothers can transmit the virus to their fetus or neonate, which may increase disease burden and decrease quality of life. To date, commercial vaccines have been developed for hepatitis A, B, and E and are available to the general population. The Advisory Committee on Immunization Practices currently accepts emergency vaccination against hepatitis A and B during pregnancy due to benefits that overweight the potential risks. While there are limited data from trials with limited numbers of samples that suggest the efficacy or safety of hepatitis B and E vaccines in pregnant women, additional data are necessary to provide evidence of vaccination during pregnancy.

Radiology has gained importance in the non-invasive diagnosis of hepatic steatosis. Ultrasonography is usually the first imaging modality for the evaluation of hepatic steatosis. Unenhanced CT with or without dual kVp measurement and MRI with in and out of phase sequence can allow objective evaluation of hepatic steatosis. However, none of the imaging modalities can differentiate non-alcoholic steatohepatitis/fatty liver disease from simple steatosis. Evaluation of hepatic steatosis is important in donor evaluation before orthotopic liver transplantation and hepatic surgery. Recently, one-stop shop evaluation of potential liver donors has become possible by CT and MRI integrating vascular, parenchymal, volume and steatosis evaluation. Moreover hepatic steatosis (diffuse, multinodular, focal, subcortical, perilesional, intralesional, periportal and perivenular), hypersteatosis and sparing (geographic, nodular and perilesional or peritumoral) can cause diagnostic problems as a pseudotumor particularly in the evaluation of oncology patients. Liver MRI is used as a problem-solving tool in these patients. In this review, we discuss the current role of radiology in diagnosing, quantifying hepatic steatosis and solutions for diagnostic problems associated with fatty infiltration and sparing.

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.

Radiation-induced liver disease (RILD) has been characterized as a veno-occlusive disease with anicteric elevation of alkaline phosphatase (ALP). However, some RILD patients present with elevated transaminase levels rather than with anicteric elevation of ALP, and these findings are common in the Asia-Pacific region where hepatitis B virus (HBV) infection is associated with 70-90% of hepatocelluar carcinoma (HCC) cases. In addition, the development of RILD is more common in patients with hepatitis B virus-related HCC. These findings indicate that susceptibility to RILD might be different in HBV carriers and non-carriers, and moreover, RILD in patients with HBV-related HCC might be associated with another unique pathogenesis such as HBV reactivation. However, HBV reactivation after hepatic irradiation has been reported in only a few studies. This study reports three cases of HBV reactivation after hepatic tomotherapy for management of HCC.

There are discrepant data on whether men or women have a higher risk for hepatic steatosis. To examine the influence of gender on hepatic adiposity in teenagers and young adults. We measured subcutaneous abdominal fat (SAF), intra-abdominal fat (IAF) and hepatic tissue density (a surrogate measure of hepatic fat) using CT in 505 healthy teenagers and young adults (254 males, 251 females; ages 15-22.9 years). Overall, compared to men, women had higher values of SAF (P 0.05). When compared to overweight and obese young women, overweight and obese young men are at greater risk for hepatic steatosis, independent of IAF. (orig.)

Diabetes and hepatitis C : A two-way association

Directory of Open Access Journals (Sweden)

Sara Salehi Hammerstad

2015-09-01

Full Text Available Diabetes and hepatitis C infection are both prevalent diseases worldwide, and are associated with increased morbidity and mortality. Most studies, but not all, have shown that patients with chronic hepatitis C are more prone to develop type 2 diabetes compared to healthy controls, as well as when compared to patients with other liver diseases including hepatitis B. Furthermore, epidemiological studies have revealed that patients with type 2 diabetes may also be at higher risk for worse outcomes of their hepatitis C infection, including reduced rate of sustained virologic response, progression to fibrosis and cirrhosis, and higher risk for development of hepatocellular carcinoma. Moreover, hepatitis C infection and mainly its treatment, interferon α, can trigger the development of type 1 diabetes. In this review we discuss the existing data on this two-way association between diabetes and hepatitis C infection with emphasis on possible mechanisms. It remains to be determined whether the new curative therapies for chronic hepatitis C will improve outcomes in diabetic hepatitis C patients, and conversely whether treatment with Metformin will reduce complications from HCV infection. We propose an algorithm for diabetes screening and follow-up in hepatitis C patients.

In patients with chronic hepatitis C (CHC), superinfection with hepatitis A (HAV) or B (HAB) viruses is associated with increased morbidity and mortality. The seroconversion rate of these patients following vaccination is considered to be lower than in healthy subjects. To evaluate the response to HAV and HBV vaccination in children with CHC. Thirty patients with CHC aged from 7.3 to 18 years were compared with 50 healthy age-, gender- and body-mass-index-matched controls. Post-vaccination serological evaluation was performed 1 month after the last dose of primary vaccination, 1 month after the booster dose and once a year during follow-up. Twenty-two patients received hepatitis A vaccine and response rate was 95.4%. Thirty patients received hepatitis B vaccine and 80% responded (hepatitis Bs titres ≥10 mIU/ml). Thirty-five controls received hepatitis A vaccine and protective anti-HAV antibodies developed in all. All of the controls were vaccinated against hepatitis B virus and 90% responded. After the whole vaccination series, overall seroprotection rates were 86% in patients and 96% in controls. No significant reduction in antibody response was observed in patients or controls during 8-years follow-up. The rate of seroconversion to the HBV vaccine is lower in patients with CHC than in healthy controls but response to HAV is adequate.

Major hepatotropic viruses continue to be important causes of acute viral hepatitis in developing countries. This work was carried out to detect the seroprevalence of hepatitis E virus (HEV) markers in children with acute viral hepatitis due to hepatotropic viruses (A, B and C) and non-A, non-B, non-C acute hepatitis, and to ascertain the influence of HEV superinfection in individuals infected with hepatitis viruses (A, B and C). We studied prospectively 162 children with sporadic acute hepatitis who reported to our hospital. Thirteen healthy controls were also included in the study. Laboratory investigations were performed, including complete liver function tests. Complete serological profiles for hepatitis viruses A, B, C and E were evaluated. HEV immunoglobulin G was detected with highest percentage among patients with hepatitis B (56.7%), followed by patients with hepatitis C virus (52.0%), hepatitis A virus (34.1%) and combined hepatitis B and C viruses (30.0%). The detection rate among patients with non-A, non-B, non-C hepatitis was 7.1%. HEV immunoglobulin M was found in 4.5% of hepatitis A virus patients and in 3.3% of hepatitis B patients. The prevalence of HEV immunoglobulin G and immunoglobulin M correlated with the levels of hepatic aspartate aminotransferase and alanine aminotransferase in patients with dual markers of infection with hepatitis E and other viruses compared to patients with acute hepatitis due to A and C viruses. HEV serological markers are common among children with acute viral hepatitis, especially from hepatitis C and B viruses. There may be increased sensitivity to HEV coinfection in association with hepatitis B and C infections. Dual infection with HEV and other hepatotropic viruses was associated with greater elevation of aspartate and alanine aminotransferases.

Semua usia dan jenis kelamin dapat dikenai dengan insiden tertinggi pada anak perempuan usia prepubertas, meskipun dapat didiagnosis pada usia 6 bulan. Hepatitis autoimun dapat diklasifikasikan menjadi 2 bagian berdasarkan adanya antibodi spesifik: Smooth Muscle Antibody (SMA dengan anti-actin specificity dan/atau Anti Nuclear Antibody (ANA pada tipe 1 dan Liver-Kidney Microsome antibody (LKM1 dan/atau anti-liver cytosol pada tipe 2. Gambaran histologisnya berupa “interface hepatitis”, dengan infiltrasi sel mononuklear pada saluran portal, berbagai tingkat nekrosis, dan fibrosis yang progresf. Penyakit berjalan secara kronik tetapi keadaan yang berat biasanya menjadi sirosis dan gagal hati.Tipe onset yang paling sering sama dengan hepatitis virus akut dengan gagal hati akut pada beberapa pasien; sekitar sepertiga pasien dengan onset tersembunyi dengan kelemahan dan ikterik progresif ketika 10-15% asimptomatik dan mendadak ditemukan hepatomegali dan/atau peningkatan kadar aminotransferase serum. Adanya predominasi perempuan pada kedua tipe. Pasien LKM1 positif menunjukkan keadaan lebih akut, pada usia yang lebih muda, dan biasanya dengan defisiensi Immunoglobulin A (IgA, dengan durasi gejala sebelum diagnosis, tanda klinis, riwayat penyakit autoimun pada keluarga, adanya kaitan dengan gangguan autoimun, respon pengobatan dan prognosis jangka panjang sama pada kedua tipe.Kortikosteroid yang digunakan secara tunggal atau kombinasi azathioprine merupakan terapi pilihan yang dapat menimbulkan remisi pada lebih dari 90% kasus. Strategi terapi alternatif adalah cyclosporine. Penurunan imunosupresi dikaitkan dengan tingginya relap.

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)

Background Hepatitis B virus (HBV) infection has many faces. Precore and core promoter mutants resemble inactive carrier status. The identification of hepatitis B core antigen (HBcAg) in hepatocytes may have variable clinical significance. The present study was undertaken to detect HBcAg in chronic hepatitis B (CHB) patients and to assess the efficacy of detection system by indirect immunofluorescence (IIF) and indirect immunoperoxidase (IIP). Materials and methods The study was done in 70 chronic HBV-infected patients. Out of 70 patients, eight (11.4%) were hepatitis B e antigen (HBeAg) positive and 62 (88.57%) were HBeAg negative. Hepatitis B core antigen was detected by indirect immunofluorescence (IIF) and indirect immunoperoxidase (IIP) methods in liver tissue. Results All HBeAg positive patients expressed HBcAg by both IIF and IIP methods. Out of 62 patients with HBeAg-negative CHB, HBcAg was detected by IIF in 55 (88.7%) patients and by IIP in 51 (82.26%) patients. A positive relation among viral load and HBcAg detection was also found. This was more evident in the case of HBeAg negative patients and showed a positive relation with HBV DNA levels. Conclusion Hepatitis B core antigen can be detected using the IIF from formalin fixed paraffin block preparation and also by IIP method. This seems to reflect the magnitudes of HBV replication in CHB. How to cite this article Raihan R, Tabassum S, Al-Mahtab M, Nessa A, Jahan M, Kabir CMS, Kamal M, Aguilar JC.

To analyze adipokine concentrations, insulin resistance and hepatic expression of suppressor of cytokine signaling 3 (SOCS-3) in patients with chronic hepatitis C genotype 1 with normal body weight, glucose and lipid profile. The study group consisted of 31 patients with chronic hepatitis C and 9 healthy subjects. Total levels of adiponectin, leptin, resistin, visfatin, omentin, osteopontin and insulin were measured using an ELISA kit. The hepatic expression of SOCS-3 was determined by the use of the reverse transcription polymerase chain reaction method. Homeostasis model assessment for insulin resistance (HOMA-IR) values were significantly higher in hepatitis C virus (HCV) infected patients without metabolic disorders compared to healthy controls (2.24 vs 0.59, P = 0.0003). Hepatic steatosis was observed in 32.2% of patients with HCV infection and was found in patients with increased HOMA-IR index (2.81 vs 1.99, P = 0.05) and reduced adiponectin level (5.96 vs 8.37, P = 0.04). Inflammatory activity (G ≥ 2) was related to increased osteopontin concentration (34.04 vs 23.35, P = 0.03). Advanced liver fibrosis (S ≥ 2) was associated with increased levels of omentin and osteopontin (436.94 vs 360.09, P = 0.03 and 32.84 vs 20.29, P = 0.03) and reduced resistin concentration (1.40 vs 1.74, P = 0.047). No correlations were reported between adipokine profile, HOMA-IR values and hepatic expression of the SOCS-3 gene. We speculated that no relationship between adipokines and HOMA-IR values may indicate that HCV can induce insulin resistance itself. Some adipokines appear to be biochemical markers of steatosis, inflammation and fibrosis in patients with chronic HCV infection. © 2014 Baishideng Publishing Group Inc. All rights reserved.

Cordero, R; Ortiz, A; Hernández, R; López, V; Gómez, M M; Mena, P

1996-09-01

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.

We wanted to identify the geographic differences in hepatic fibrosis and their associations with the atrophy-hypertrophy complex in patients with chronic viral hepatitis using the dual-contrast material-enhanced MRI (DC-MRI) with gadopentetate dimeglumine and ferucarbotran. Patients with chronic C (n = 22) and B-viral hepatitis (n = 35) were enrolled for determining the subjective grade of fibrosis (the extent and thickness of fibrotic reticulations) in the right lobe (RL), the caudate lobe (CL), the medial segment (MS) and the lateral segment (LS) of the liver, with using a 5-grade scale, on the gradient echo T2-weighted images of DC-MRI. The fibrosis grades of different segments were compared using the Kruskal-Wallis test followed by post-hoc analysis to establish the segment-by-segment differences. The incidences of two pre-established morphologic signs of cirrhosis were also compared with each other between the two groups of patients. There were significant intersegmental differences in fibrosis grades of the C-viral group (p = 0.005), and the CL showed lower fibrosis grades as compared with the grades of the RL and MS, whereas all lobes were similarly affected in the B-viral group (p = 0.221). The presence of a right posterior hepatic notch was significantly higher in the patients with intersegmental differences of fibrosis between the RL and the CL (19 out of 25, 76%) than those without such differences (6 out of 32, 19%) (p < 0.001). An expanded gallbladder fossa showed no significant relationship (p = 0.327) with the segmental difference of the fibrosis grades between the LS and the MS. The relative lack of fibrosis in the CL with more advanced fibrosis in the RL can be a distinguishing feature to differentiate chronic C-viral hepatitis from chronic B-viral hepatitis and this is closely related to the presence of a right posterior hepatic notch.

Full Text Available El rápido incremento de las tasas de SIDA en el mundo a incrementado el interés de los investigadores en las enfermedades de transmisión sexual. Una forma alternativa de transmisión son las transfusiones, de ahí la importancia de conocer acerca de métodos destinados a evitar dicha transmisión. Objetivos: Determinar la seroprevalencia de sífilis, hepatitis B y VIH en donantes de sangre e, identificar características distintivas entre seropositivos y seronegativos que identifiquen donantes de riesgo. Material y métodos: Se elaboró un estudio retrospectivo tipo descriptivo en su primera parte y caso-control en la segunda. Fueron 12700 donantes los incluidos en el estudio sobre prevalencia y 111 casos seropositivos con 691 controles seronegativos en el estudio comparativo. Resultados: Se encontró una prevalencia de 1.06% de casos VDRL positivos (135/12700, 0.81% de HBsAg positivos (103/12700 y 0.11% de casos VIH positivos (13/12700. El 15.3% (14/91 de seropositivos y el 12.45% (86/691 de seronegativos tuvo al menos uno de los siguientes antecedentes: receptor de transfusiones en los 6 meses previos, extracción dental, acupuntura o relaciones sexuales con prostitutas; 427 controles (63.3% y 47 seropositivos (51.6% manifestaron donar por primera vez (p<0.05. Conclusiones: Las pruebas serológicas para descartar sífilis han sido cuestionadas, pero su uso en nuestro medio esta justificado por que permite identificar donantes de riesgo. Las cifras encontradas, no son las reales de sífilis por carencia de una prueba confirmatoria, y son compatibles con otros reportes. Por otro lado, hepatitis B constituye un porcentaje menor de casos de hepatitis viral post transfusional existiendo amplia literatura al respecto; los valores encontrados en nuestro estudio son compatibles con reportes previos. El VIH se ha incorporado hace relativamente poco al riesgo de infección por transfusiones. Los valores que reportamos son semejantes a estudios

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.

Full Text Available Studies suggest 2 per 1000 people in Dublin are living with HIV, the level above which universal screening is advised. We aimed to assess the feasibility and acceptability of a universal opt-out HIV, Hepatitis B and Hepatitis C testing programme for Emergency Department patients and to describe the incidence and prevalence of blood-borne viruses in this population.An opt-out ED blood borne virus screening programme was piloted from March 2014 to January 2015. Patients undergoing blood sampling during routine clinical care were offered HIV 1&2 antibody/antigen assay, HBV surface antigen and HCV antibody tests. Linkage to care where necessary was co-ordinated by the study team. New diagnosis and prevalence rates were defined as the new cases per 1000 tested and number of positive tests per 1000 tested respectively.Over 45 weeks of testing, of 10,000 patient visits, 8,839 individual patient samples were available for analysis following removal of duplicates. A sustained target uptake of >50% was obtained after week 3. 97(1.09%, 44(0.49% and 447(5.05% HIV, Hepatitis B and Hepatitis C tests were positive respectively. Of these, 7(0.08%, 20(0.22% and 58(0.66% were new diagnoses of HIV, Hepatitis B and Hepatitis C respectively. The new diagnosis rate for HIV, Hepatitis B and Hepatitis C was 0.8, 2.26 and 6.5 per 1000 and study prevalence for HIV, Hepatitis B and Hepatitis C was 11.0, 5.0 and 50.5 per 1000 respectively.Opt-out blood borne viral screening was feasible and acceptable in an inner-city ED. Blood borne viral infections were prevalent in this population and newly diagnosed cases were diagnosed and linked to care. These results suggest widespread blood borne viral testing in differing clinical locations with differing population demographic risks may be warranted.

Hepatic angiography: Portal hypertension

Oliver, T.W. Jr.; Sones, P.J. Jr.

1985-01-01

Portal hypertension is usually a manifestation of underlying hepatic parenchymal disease, although it may be secondary to portal or hepatic venous thrombosis and rarely to hyperdynamic portal states. Portal hypertension may present as encephalopathy, ascites, jaundice, hepatic failure, or catastrophic upper gastrointestinal hemorrhage. Radiologic investigation should include indirect or direct measurements of portal pressure, assessment of portal venous perfusion, visualization of collaterals, and demonstration of arterial and venous anatomy for potential shunt procedure. Following survival of initial variceal bleeding, the most effective procedure to prevent recurrent hemorrhage is a shunt to decompress the varices. The decision whether to intervene medically or surgically during the acute hemorrhagic episode as well as the type of shunt used to prevent future hemorrhage is the subject of continuing controversy

The aim of this study was to examine the efficacy of combined immunization of hepatitis B immunoglobulin (HBIG) and hepatitis B vaccine (HBVac) in blocking father-infant transmission of hepatitis B virus (HBV). Newborns positive at birth for blood HBV sur-face antigen (HBsAg) and/or HBV DNA were selected and immunized with HBIG combination HBVac. At 7 months, HBV markers and HBV DNA of each neonate were measured using electrochemiluminescence with the Cobas-e-411 Automatic Electrochemiluminescence Immuno-assay Analyzer and fluorescence quantitative polymerase chain reaction. Among all 7-month-old subjects, the negative conversion rates of HBV DNA and HBsAg were 48/61 (78.7%) and 19/41 (46.3%), respectively. Therefore, this study demonstrated that prompt combination injection of HBIG and HBVac can protect some of the HBV DNA- and/ or HBsAg-positive newborns from HBV.

2014-11-01

This study presents a detailed description of the distribution, diameters and drainage patterns of hepatic veins on the basis of the corrosion cast analysis in 18 dogs. We classified the hepatic veins in three main groups: the right hepatic veins of the caudate process and right lateral liver lobe, the middle hepatic veins of the right medial and quadrate lobes and the left hepatic veins of both left liver lobes and the papillary process. The corrosion cast study showed that the number of the veins in the Nomina Anatomica Veterinaria and most anatomical textbooks is underestimated. The number of various-sized hepatic veins of the right liver division ranged from 3 to 5 and included 1 to 4 veins from the caudate process and 2 to 4 veins from the right lateral liver lobe. Generally, in all corrosion casts, one middle-sized vein from the right part of the right medial lobe, which emptied separately in the caudal vena cava, was established. The other vein was a large-sized vein from the remainder of the central division, which frequently joined the common left hepatic vein from the left liver lobes. The common left hepatic vein was the largest of all the aforementioned hepatic veins.

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.

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

Con A hepatitis is regarded as a T cell-mediated model of acute liver injury. Mincle is a C-type lectin receptor that is critical in the immune response to mycobacteria and fungi but does not have a well-defined role in preclinical models of non-pathogen-mediated inflammation. Because 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 hypoxia-inducible factor-1α (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 C-type lectin receptors 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 HIF-1α 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.

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)

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.

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

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.

To determine the molecular epidemiology of Hepatitis C virus (HCV) in K.S.A. 492 histological proven chronic HCV patients recruited from all regions of KSA,between November 1999 and March 2002 were genotyped and subtyped using amplified products of specific primers from the 5-UTR region in a reverse transcription polymerase chain reaction followed by a hybridization technique. 62% of Saudis were found to be genotype4. Other genotypes were 1(24.1%); 2(7.4%); 3(5.9%); 5(0.3%) add 10(0.3%).All regions showed similar distribution except except the Eastern region where subtype 2a/c emerged. 86% of Saudi chronic hepatitis C cases are due to genotypes 1 and 4.Since these are considered difficult to treat an aggressive approach to management using combination therapy of pegylated interferon plus ribavirin for 48 weeks should be considered for all cases of chronic hepatitis C until genotyping proves otherwise.

Studies on the hepatic hemodynamics of the patients with fatty liver by hepatic blood flow mapping

International Nuclear Information System (INIS)

Kubo, Shuichi; Okajima, Tugio; Yamazaki, Yasurou

1991-01-01

To investigate intrahepatic hemodynamics of the patients with fatty liver, the time to reach maximal enhancement (PT) of every 3 x 3 pixel was depicted by a gray scale throughout an area of maximal horizontal slice of CT of the liver to obtain blood flow mapping of the liver, and compared with those of normal, chronic hepatitis and cirrhosis. Mottles of deep gray, light gray or black pixels were distributed throughout the liver slice of fatty liver. Although the mean PT of a ROI of fatty liver was longer than normal and shorter than that of cirrhosis and the same as that of chronic hepatitis, the map of fatty liver was different from that of chronic hepatitis. When the distribution of PT was expressed by their histogram, it was known that PT of fatty liver had a wider range than that of chronic hepatitis. The range was the same as that of cirrhosis. In one case of fatty liver, the deep gray pixels was increased when fatty infiltration of the liver was improved. It was concluded that the intrahepatic blood flow of fatty liver was impaired in a way not similar to chronic hepatitis or liver cirrhosis, which could be clearly seen by hepatic blood flow mapping, and which seemed to be reversible with the improvement of fatty liver.

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 effectivehepatic 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.

Computed tomography scans of 114 metastatic hepatic tumors were reviewed. Central low density was found in 82 cases (71.9%) and seems to be characteristic to metastatic hepatic tumors. Dynamic CT was performed on 34 cases, and 21 (61.8%) of these had ring enhancement at the arterial phase. Most of metastatic hepatic tumors could be differentiated from hepatocellular carcinoma. However, metastatic hepatic tumors from renal cell carcinoma, renal rhabdomyosarcoma, malignant melanoma and leiomyosarcoma could not be differentiated from hepatocellular carcinoma, even with use of dynamic study.

Direct-acting antivirals for chronic hepatitis C

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.

Malaysia is multiethnic, with a population of 31,127,247 comprising a mixture of Malays (50.1%), Chinese (22.6%), Indians (6.7%), Aborigines (11.8%), others (0.7%), and noncitizens (8.2%). Like other countries in the region, viral hepatitis is an important public health problem in Malaysia. The 3 most common causes for hepatitis in Malaysia are hepatitis A, B, and C. Hepatitis A has been a reportable disease in Malaysia since 1988. Due to the introduction of government control programs, the national incidence rate has dropped steadily. It is now estimated that 50% of Malaysians less than 30 years of age do not have antibodies to hepatitis A and are therefore susceptible to the disease, which can be prevented by reinforcing the hygiene status of the general population. Malaysia is a country of medium seroprevalence for the hepatitis B virus (HBV) surface antigen (HBsAg) in the general population (1.5-9.8%). The major route of transmission is from infected mother to fetus. There are an estimated 1 million people chronically infected with hepatitis B in Malaysia. Approximately 75% of all viral hepatitis cases are due to hepatitis B infection, with a male-to-female ratio of 2:1. Chronic hepatitis B (CHB) accounts for more than 80% of the hepatocellular carcinoma (HCC) cases seen in Malaysia and HCC is the 3rd most common malignant neoplasm and among the 10 leading causes of death. Most common genotypes are B and C. Incidence rates among Chinese, Malays, and Indians are 36, 26, and 15% respectively. The hepatitis B vaccination program for children was introduced in 1989, which successfully managed to reduce the seroprevalence of infection among Malaysians to 0.01% (graph 4, 2014). But the disease burden will still remain high for some time as the infected people are getting older and living longer. Hepatitis C virus (HCV) infection is a growing problem in Malaysia. An estimated 453,700 people were living with HCV infection in Malaysia in 2009 (2.5% of the population

RECENT THEORIES OF PATHOGENESIS OF HEPATIC ENCEPHALOPATHY IN HEPATITIS C VIRAL INFECTION

Full Text Available Hepatic encephalopathy is potentially reversible, or progressive neuropsychiatric syndrome characterized by changes in cognitive function, behavior and personality changes, and transient neurologic symptoms and characteristic electroencephalographic patterns associated with acute and chronic liver failure. For some time, there has been controversy regarding the origin of toxins responsible for the change of mental state. It was found that the occurrence of hepatic encephalopathy is responsible for multiple organ peripheral changes (intestinal changes, abnormalities of portal-systemic circulation, liver failure, loss of muscle tissue, changes in brain intracellular communication (osmotic changes, astrocytes and axonal abnormalities in communication, changes in cerebral perfusion and ammonia, endogenous benzodiazepines, gamma amino butyric acid, derivatives of methionine and false neurotransmitters. The aforementioned metabolic factors that contribute to the development of hepatic encephalopathy are not mutually exclusive and multiple factors may be present at the same time.

Parvovirus B19 infection can present with myriads of clinical diseases and syndromes; liver manifestations and hepatitis are examples of them. Parvovirus B19 hepatitis associated aplastic anemia and its coinfection with other hepatotropic viruses are relatively underrecognized, and there is sufficient evidence in the literature suggesting that B19 infections can cause a spectrum of liver diseases from elevation of transaminases to acute hepatitis to fulminant liver failure and even chronic hepatitis. It can also cause fatal macrophage activation syndrome and fibrosing cholestatic hepatitis. Parvovirus B19 is an erythrovirus that can only be replicate in pronormoblasts and hepatocytes, and other cells which have globosides and glycosphingolipids in their membrane can also be affected by direct virus injury due to nonstructural protein 1 persistence and indirectly by immune mediated injury. The virus infection is suspected in bone marrow aspiration in cases with sudden drop of hemoglobin and onset of transient aplastic anemia in immunosuppressed or immunocompetent patients and is confirmed either by IgM and IgG positive serology, PCR analysis, and in situ hybridization in biopsy specimens or by application of both. There is no specific treatment for parvovirus B19 related liver diseases, but triple therapy regimen may be effective consisting of immunoglobulin, dehydrohydrocortisone, and cyclosporine.

The diagnosis of hepatic rupture in patients with pregnancy-induced hypertension (preeclampsia and eclampsia) is rarely made preoperatively. Diagnostic imaging can be utilized in some patients to confirm the preoperative diagnosis. Since hematoma formation precedes hepatic rupture, then, when diagnostic modalities such as sonography and computed tomography identify patients with hematomas, these patients are at risk of rupture, and should be hospitalized until the hematomas resolve

To evaluate the contrast between hepatic vein and hepatic parenchyma with controlled velocities of ultrasound in normal and fatty liver. 31 patient with normal liver and 39 patients with moderate degree of fatty liver were studies with sonography with controlled velocities of ultrasound (1,580 m/sec, 1,540 m/sec, 1,500 m/sec, 1,460 m/sec). Sonographic images were captured with picture grabbing (Sono-PACS) and were recalled with visual C++(Microsoft Redmond. WA, USA). The contrast between hepatic vein and parenchyma was measured and analyzed on each sonographic image. The number of patients with the highest contrast between hepatic vein and hepatic parenchyma among the 31 patients with normal liver were 5 (16.1%) with 1,580 m/sec, 12 (38.8%) with 1,540 m/sec, 9 (29.0%) with 1,500 m/sec, and 5 (16.1%) with 1,460 m/sec. The number of patients with highest contrast between hepatic vein and hepatic parenchyma among the 39 patients with fatty liver were 3 (7.7%) with 1,580 m/sec, 7 (17.9%) with 1,540 m/sec, 12 (30.8%) with 1,500 m/sec and 17 (43.6%) with 1,460 m/sec. The velocity of ultrasound for the highest contrast between hepatic vein and hepatic parenchyma in normal liver was 1,540 m/sec, and 1,460 m/sec in fatty liver.

Hepatic macrophage complement receptor clearance function following injury.

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.

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

Baseline MELD score predicts hepatic decompensation during antiviral therapy in patients with chronic hepatitis C and advanced cirrhosis.

Directory of Open Access Journals (Sweden)

Georg Dultz

Full Text Available In patients with advanced liver cirrhosis due to chronic hepatitis C virus (HCV infection antiviral therapy with peginterferon and ribavirin is feasible in selected cases only due to potentially life-threatening side effects. However, predictive factors associated with hepatic decompensation during antiviral therapy are poorly defined.In a retrospective cohort study, 68 patients with HCV-associated liver cirrhosis (mean MELD score 9.18 ± 2.72 were treated with peginterferon and ribavirin. Clinical events indicating hepatic decompensation (onset of ascites, hepatic encephalopathy, upper gastrointestinal bleeding, hospitalization as well as laboratory data were recorded at baseline and during a follow up period of 72 weeks after initiation of antiviral therapy. To monitor long term sequelae of end stage liver disease an extended follow up for HCC development, transplantation and death was applied (240 weeks, ± SD 136 weeks.Eighteen patients (26.5% achieved a sustained virologic response. During the observational period a hepatic decompensation was observed in 36.8%. Patients with hepatic decompensation had higher MELD scores (10.84 vs. 8.23, p14, respectively. Baseline MELD score was significantly associated with the risk for transplantation/death (p<0.001.Our data suggest that the baseline MELD score predicts the risk of hepatic decompensation during antiviral therapy and thus contributes to decision making when antiviral therapy is discussed in HCV patients with advanced liver cirrhosis.

Hepatitis E: Discovery, global impact, control and cure.

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.

2004-01-01

The hepatic artery aneurysms are rare, especially in interahepatic branches, The frequency consists of 75-80% extrahepatic and 20-25% intrahepatic. Catheterization is achieved usually from common femoral artery, other methods implemented in the case of unsuccessful catheterization from femoral artery, are translumbar and brachial catheterization. The study consist of 565 patients that were referred to the angiography ward, During seven years of assessment, five cases of hepatic artery aneurysm were found; this is a rare condition reported in the English literature. In the literature as well as in this case report the hepatic artery aneurysms are rare. In reported series the extrahepatic artery aneurysms are found more often than in the intrahepatic artery aneurysm but in this case report intrahepatic artery aneurysms are more than extrahepatic one.

In medical terms, occupational diseases are defined as health disorders specifically associated with the working environment of people and their occupational activity. From the medical and legal perspectives, the vast majority of European countries consider particular diseases to be of occupational origin if they are mentioned in the current list of occupational diseases and caused by exposure to factors in the working environment that are harmful to health. The aim of this study was to analyze the occurrence of cases of viral hepatitis certified as an occupational disease in Poland during 1979-2009. This article presents the medical, economic, and legal aspects of the epidemiology of hepatitis as an occupational disease in Poland. Publically available statistical data on certified occupational diseases in Poland and data contained in individual "occupational disease diagnosis cards" (based on data used in Poland statistical form), regarding certified cases of hepatitis among health care professionals, which were collected by the Department of Occupational Hygiene of the Polish Public Health Service, were analyzed in this study. In Poland, the highest number of cases of hepatitis certified as an occupational disease was observed in 1987. A gradual reduction in the number of cases of hepatitis as an occupational disease has been noted since then. Currently, hepatitis C as an occupational disease is certified more frequently than hepatitis B. In Poland, the number of women with hepatitis certified as an occupational disease is higher than that of men. However, among health care professionals, particularly nurses, this difference is insignificant because women outnumber the men. The existence of such a situation is due to the significant quantitative predominance of women over men among medical personnel, especially among nurses. Immunization of health care professionals against the hepatitis B virus (HBV), introduced in Poland in 1988, was an important factor

Viral hepatitis A (VHA) is the disease which has an ancient history. Reports of epidemic jaundice were described by Hippocrates in Greece during the 5th century B.C. Incidence of VHA in developed countries is dropping in last decades. What was once common disease is now very rare, usually emerging in local epidemies. With decreasing incidence of hepatitis A clinicians losing practical experiences with disease. Authors present possible diagnostic and therapeutic problems based on their experience with large epidemic of hepatitis A, which occurred in 2016-2017 in Brno area.Key words: hepatitis A (VHA) - hepatitis A virus (HAV).

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.
