  1. Acute pancreatitis in acute viral hepatitis

    2007-01-01

    AIM: To elucidate the frequency and characteristics of pancreatic involvement in the course of acute (nonfulminant) viral hepatitis.METHODS: We prospectively assessed the pancreatic involvement in patients with acute viral hepatitis who presented with severe abdomimanl pain.RESULTS: We studied 124 patients with acute viral hepatitis, of whom 24 presented with severe abdominal pain. Seven patients (5.65%) were diagnosed to have acute pancreatitis. All were young males. Five patients had pancreatitis in the first week and two in the fourth week after the onset of jaundice. The pancreatitis was mild and all had uneventful recovery from both pancreatitis and hepatitis on conservative treatment.The etiology of pancreatitis was hepatitis E virus in 4,hepatitis A virus in 2, and hepatitis B virus in 1 patient.One patient had biliary sludge along with HEV infection.The abdominal pain of remaining seventeen patients was attributed to stretching of Glisson's capsule.CONCLUSION: Acute pancreatitis occurs in 5.65% of patients with acute viral hepatitis, it is mild and recovers with conservative management.

  6. US findings in acute viral hepatitis

    Reports on colecystic alterations during acute viral hepatitis are more and more frequent; the pathogenesis and clinical meaning of these alterations are still debated. Consensual periportal lymphnode enlargment has been not yet reported. The authors describe four cases of acute viral hepatites in whichUS showed alterations of colecystic walls and/or contents; in two cases enlarged periportal lymphnodes were demonstrated too. Later US exams showed a complete regression of both colecystic and lymphnodal lesions. Clinical findings and laboratory out-comes are evaluated; the connection of US results with hepatitis and its meaning are discussed. The causes of colecystic alterations are still questionable; they might be related to blood disorders or to an increased portal pressure, or else they might be considered as phlogistic lesions. The authors conclude that both colecystic and lymphnodal alterations have a phlogistic nature; moreover, they are not related to a particulary evolution of hepatitis. The importance of distinguishing colecystic alterations from different pathology is stressed

  10. Acute hepatitis e viral infection in pregnancy and maternal morbidity

    To determine the maternal morbidity in pregnant women with acute hepatitis E viral infection. Study Design: Observational, cross-sectional study. Place and Duration of Study: Departments of Obstetrics and Gynaecology and Medicine, Liaquat University of Medical and Health Sciences, Jamshoro, Red Crescent General Hospital and Saint Elizabeth Hospital, Hyderabad, from January 2011 to December 2013. Methodology: The study population was pregnant women with acute hepatitis E infection confirmed by ELIZA technique. Pregnant women with other hepatic viral infections were excluded. All medical and obstetric conditions, and mortality were noted on the predesigned proforma. Results: Out of the total 45 admitted pregnant women with hepatitis E viral infection, 22 women (48.9%) had severe morbidity. The most common were hepatic coma in 8 (36.36%) cases and disseminated intravascular coagulation in 14 (63.63%) cases. Highest mortality rate was seen in women with hepatic coma (100%), while in those with disseminated intravascular coagulation, one out of the 14 cases (7.14%) died. Conclusion: The acute viral hepatitis E infection in pregnant women is associated with maternal morbidities and high mortality rate. (author)

    2001-07-01

    Full Text Available Hepatomegaly, decrease in the liver paranchymal echo and increase in the gallbladder wall thickness has been shown in acute viral hepatitis. The present study was done to determine sonographic changes in acute viral hepatitis. We performed liver and bile ducts sonography and specific tests on 42 patients (mean age: 31.5 and 61% male with acute viral hepatitis. Gallbladder wall thickness was seen in 45.2% and hepatomegaly in 33.3% of patients and liver paranchymal echo was decreased in 19.3%. Age, sex, type of hepatitis, cholecystitis like symptoms, aspartate aminotransfrase, alanine aminotransfrase, alkaline phosphatase and bilirubin did not significantly corralate with these changes. Only raised prothrombin time was strongly correlated to the thickening of the gallbladder and decrease in the liver paranchymal echo and cholesistic like symptoms we can postulate that thickening of the gallbladder and decrease in the liver paranchymal echo is not dependent on the severity and speed of the paranchymal necrosis (as considered with ALT and AST but they depend on the liver function disturbance (as considered with PT because the thickening of the gall bladder is present in 45% of the patients and 10% of the normal population have gallbladder stones, one should not perform the diagnosis of acute cholecystitis, only on the basis of sonographic report without attention to the clinical and laboratory data.

  12. Transient nephritis during resolution phase of acute virale hepatitis E

    2009-01-01

    Hepatitis E Virus is a causative agent of hepatitis. Viral E hepatitis is responsible for various clinical manifestations. However, immune reactions due to hepatitis E virus are rarely encountered. A case of membranoproliferative glomerulonephritis associated with hepatitis E virus is reported her.

  13. Nonvisualization of the gallbladder lumen on sonogram: a sign of acute viral hepatitis

    Six cases of nonvisulization of the gallbladder lumen in patients with acute viral hepatitis are presented. Follow-up ultrasonographic examinations done during the convalescent period in 2 patients showed normal gallbladders and this was correlated with improvement in enzyme levels. It is suggested that acute viral hepatitis should be considered in the differential diagnosis of nonvisualization of the gallbladder lumen on sonogram.

  17. In situ hybridization studies of hepatitis A viral RNA in patients with acute hepatitis A

    In situ hybridization with oligonucleotide probes has been used to localise hepatitis A virus RNA genomic sequences in formalin-fixed and routinely processed human liver biopsies from three patients. Using radiolabelled Sulphur-35 antisense probes, viral genomic sequences were found in all three cases, but signal intensity was greatest in cases 1 and 2 with fulminant hepatitis, and was minimal in the third case of resolving hepatitis biopsied 2 months after acute illness. Localisation showed the viral RNA to be present in hepatocytes, sinusoidal cells and inflammatory cells in and around the portal tracts. Both cases showed signal in similar cell types, but the distribution of staining was predominantly periportal in case 1, whereas lobular staining was more apparent in case 2. Hybridization with sense polarity probes failed to detect any evidence of replicative intermediates of antigenomic viral RNA. The presence of hepatitis A RNA in phagocytic cells was confirmed using immunohistochemistryfor a macrophage marker, CD68, combined with in situ hybridization. In all cases the signal was predominantly cytoplasmic, and this was confirmed with the use of tritiated probes. (au)

  18. Plasma and urine biomarkers in acute viral hepatitis E

    Aggarwal Rakesh

    2009-10-01

    Full Text Available Abstract Background Hepatitis E, caused by the hepatitis E virus (HEV, is endemic to developing countries where it manifests as waterborne outbreaks and sporadic cases. Though generally self-limited with a low mortality rate, some cases progress to fulminant hepatic failure (FHF with high mortality. With no identified predictive or diagnostic markers, the events leading to disease exacerbation are not known. Our aim is to use proteomic tools to identify biomarkers of acute and fulminant hepatitis E. Results We analyzed proteins in the plasma and urine of hepatitis E patients and healthy controls by two-dimensional Differential Imaging Gel Electrophoresis (DIGE and mass spectrometry, and identified over 30 proteins to be differentially expressed during acute hepatitis E. The levels of one plasma protein, transthyretin, and one urine protein, alpha-1-microglobulin (α1m, were then quantitated by enzyme immunoassay (EIA in clinical samples from a larger group of patients and controls. The results showed decreased plasma transthyretin levels (p Conclusion Our results demonstrate the utility of characterizing plasma and urine proteomes for signatures of the host response to HEV infection. We predict that plasma transthyretin and urine α1m could be reliable biomarkers of acute hepatitis E. Besides the utility of this approach to biomarker discovery, proteome-level changes in human biofluids would also guide towards a better understanding of host-virus interaction and disease.

    Full Text Available Acute viral hepatitis (AVH is a major public health problem and is an important cause of morbidity and mortality in the developing countries. AIM: The aim of the present study is to study the serological profile of acute viral hepatitis in children and adults admitted in King George Hospital, Visakhapatnam and also age and sex distribution of patients suffering from acute viral hepatitis and also comparing the etiological profile by studying serological markers of common viral agents. SUBJECTS AND METHODS: Samples were collected from 80 individuals with jaundice and other clinical and biochemical evidences of acute viral hepatitis . They were tested for hepatitis surface antigen, HBcIgM, HAVIgM, HEVIgM, Antibodies to HCV by the enzyme - linked immuno sorbent assay. RESULTS: Out of the 80 viral hepatitis cases (47 adults+33 children. In adults 20(42.5% patients presented HBV (26.96% was identified as the most common cause of acute hepatitis followed by HEV14 (29.8%, HEV+HAV4 (8.5% and HAV 6(12.76%. Co - infections with more than one virus were present in 5cases; HAV - HEV co - infection being the most common. In children 16(48.5% presented with HAV, HAV+HEV11 (33.3%, HEV4 (12.12%, HBV1 (3.03% CONCLUSIONS: Vaccination of adults against hepatitis B is indicated, along with sexual education to decrease the incidence of hepatitis which is found as common etiological agent in adults. The incidence of HAV and HEV in children shows that there is need for improvement in sanitation and food habits.

    Herpes simplex viral hepatitis is uncommon in immunocompetent subjects. It is a difficult diagnosis to establish because of the high absence rate of mucocutaneous involvement. We report here a 38-year-old woman who was diagnosed to have herpes simplex virus hepatitis. The patient was neither pregnant nor immunocompromised. She got well in a short period only by a supportive treatment. Herpes simplex virus should be included in differential diagnosis of acute hepatitis even in immunocompetent ...

  1. [Viral hepatitis in travellers].

    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

    2009-03-01

    Full Text Available Abstract Background In Uzbekistan, routine serologic testing has not been available to differentiate etiologies of acute viral hepatitis (AVH. To determine the age groups most affected by hepatitis E virus (HEV during documented AVH epidemics, trends in AVH-associated mortality rate (MR per 100,000 over a 15-year period and reported incidence of AVH over a 35-year period were examined. Methods Reported AVH incidence data from 1971 to 2005 and AVH-associated mortality data from 1981 to 1995 were examined. Serologic markers for infection with hepatitis viruses A, B, D, and E were determined from a sample of hospitalized patients with AVH from an epidemic period (1987 and from a sample of pregnant women with AVH from a non-epidemic period (1992. Results Two multi-year AVH outbreaks were identified: one during 1975–1976, and one during 1985–1987. During 1985–1987, AVH-associated MRs were 12.3–17.8 per 100,000 for the general population. Highest AVH-associated MRs occurred among children in the first 3 years of life (40–190 per 100,000 and among women aged 20–29 (15–21 per 100,000. During 1988–1995 when reported AVH morbidity was much lower in the general population, AVH-associated MRs were markedly lower among these same age groups. In 1988, AVH-associated MRs were higher in rural (21 per 100,000 than in urban (8 per 100,000 populations (RR 2.6; 95% CI 1.16–5.93; p Conclusion In the absence of the availability of confirmatory testing, inferences regarding probable hepatitis epidemic etiologies can sometimes be made using surveillance data, comparing AVH incidence with AVH-associated mortality with an eye to population-based viral hepatitis control measures. Data presented here implicate HEV as the probable etiology of high mortality observed in pregnant women and in children less than 3 years of age in Uzbekistan during 1985–1987. High mortality among pregnant women but not among children less than 3 years has been observed in

    Full Text Available The present study aimed to find out the prevalence and severity of acute viral hepatitis and fulminant hepatitis during pregnancy in North India. The study was conducted on 97 consecutive pregnant patients in third trimester with acute viral hepatitis (AVH or fulminant hepatic failure (FHF. The patients were evaluated on the basis of history, examination, liver function profile and serological markers for hepatitis A,B,C and E viruses. Hepatitis E virus (HEV was the causative agent in 47.4% of the cases of viral hepatitis and 52.6% were caused by non-E viruses(HAV-5.2%,HBV-7.2%,HCV-0%,non A-E 47.4%. HEV was responsible for 36.2% of the cases of AVH and 75% of the cases of FHF. The mortality was 24.7% (24/97. All of them had FHF. Eighteen of 24 cases (75% who expired were HEV positive. The mortality rate was 39.1% in HEV group and 11.7% in non HEV group. Majority of patients (87.5% who expired had died undelivered. Hepatitis E was the commonest etiological agent in those who had fulminant disease during pregnancy and was associated with high mortality rate.

    2015-01-01

    Full Text Available Background: Hepatitis A virus (HAV and Hepatitis E virus (HEV are both enterically transmitted, resulting in acute viral hepatitis (AVH in developing countries. They pose major health problems in our country. This study was done to determine prevalence of HAV and HEV in patients presenting with AVH and the co-infection of HAV and HEV in these patients. Materials and Methods: A cross-sectional study of 2-years duration was conducted in the Department of Microbiology, KMC, Mangalore. A non-random sampling of 958 patients presenting with AVH was considered in the study. On the basis of history, serum samples were analysed for IgM anti-HAV and IgM anti-HEV for the detection of HAV and HEV, respectively using commercially available ELISA kits. Data collected was analysed by using Statistical Package for the Social Sciences (SPSS version 11.5. Results: The seroprevalence of HAV- and HEV-positive patients were 19.31% and 10.54%, respectively. The seroprevalence of both HAV and HEV in patients with acute viral hepatitis was 11.5%. The prevalence of HAV and HEV among males (68% and 31% was higher than in females (31% and 20% and was predominantly seen among young adults. These infections were predominantly seen during end of monsoons and beginning of winter. Conclusion: Though the prevalence of HAV is much higher than that of HEV, co-infection rate of 11.5% mandates the screening for HEV which will be of immense importance in pregnant women and improving levels of personal hygiene among higher socio-economic population. These data will be essential for planning of future vaccination strategies and for better sanitation programme in this part of the country.

    Hyun Woong Lee

    Full Text Available Clinical manifestations of hepatitis A virus (HAV infection vary from mild to fulminant hepatic failure (FHF in adults. We investigated the relationship between laboratory findings, including viral load, and clinical outcomes in patients with acute hepatitis A (AHA and evaluated predictive factors for severe acute hepatitis (s-AH.We analyzed the clinical manifestations of AHA in 770 patients. Patients with a prothrombin time (PT of less than 40% of normal were classified as s-AH and included 4 patients with FHF, 11 patients with acute renal failure, and 3 patients with prolonged jaundice (n = 128. Other patients were defined as mild acute hepatitis (m-AH (n = 642. Serum samples were obtained from 48 patients with acute hepatitis A. Among them, 20 with s-AH, and 28 with m-AH, were tested for HAV RNA titer.In a multivariate analysis, age (HR = 1.042, P = 0.041, peak creatinine (HR = 4.014, P = 0.001, bilirubin (HR = 1.153, P = 0.003, alanine aminotransferase (ALT (HR = 1.001, P < 0.001, initial lactate dehydrogenase (LDH (HR = 1.000, P = 0.045 and total cholesterol (HR = 0.978, P < 0.001 were independent factors for s-AH. Serum HAV RNA was detected in 20/20 (100% patients with s-AH and 22/28 (78.6% patients with m-AH. In a multivariate analysis of the 48 patients who were tested for HAV RNA, peak ALT (HR = 1.001, P = 0.004 and HAV RNA titer (HR = 2.076, P = 0.012 were independent factors for s-AH.Clinical factors including age, peak creatinine, bilirubin, ALT, initial LDH and total cholesterol were independent factors for s-AH in a multivariate analysis. In particular, HAV load strongly correlated with the severity of hepatitis A.

  11. Use of N-Acetylcysteine in Children with Fulminant Hepatic Failure Caused by Acute Viral Hepatitis

    Objective: To determine the efficacy of N-acetylcysteine (NAC) in children aged > 1 month to 16 years admitted with Fulminant Hepatic Failure (FHF) secondary to Acute Viral Hepatitis (AVH) in a tertiary care center of a developing country. Study Design: Analytical study. Place and Duration of Study: Department of Paediatrics, The Aga Khan University Hospital, Karachi, Pakistan, from January 2007 to December 2011. Methodology: Medical records of children (> 1 month - 16 years) with FHF admitted with AVH of known etiology who received NAC were reviewed retrospectively. Liver function tests (mean ± SD) at baseline, 24 hours after NAC and before or at the time of discharge/death were recorded and compared via using repeated measures ANOVA(r-ANOVA). Efficacy of NAC is defined in improvement in biochemical markers, liver function test and discharge disposition (survived or died). Mortality associated risk factors were identified by using logistic regression analysis. P-value and 95 percentage confidence interval were recorded. Results: Forty children (mean age was 80 ± 40 months) with FHF secondary to AVH received NAC. Majority were males (n=25; 63 percentage). Vomiting (75 percentage) and jaundice (65 percentage) were the main presenting symptoms, one-third had hypoglycemic, while 40 percentage had altered sensorium at the time of admission. There was significant statistical difference in liver enzymes and prothrombin time on admission comparing at discharge in children received NAC (p < 0.001). Fifteen (38 percentage) children died. Severe vomiting (Odds Ratio (OR) 0.22, 95 percentage Confidence Interval (CI) 0.05 - 0.8), jaundice (OR 9.3, CI 1.1 - 82.6), inotropic support (OR 20.6, CI 3.5 - 118.3) and mechanical ventilation (OR 4.3, CI 1.1 - 16.6) at the time of admission are associated with risk factors for mortality in children with FHF secondary to AVH. Conclusion: NAC used in children with FHF secondary to AVH is associated with markedly improved liver function

  12. Serum Hyperamylasemia as a prognostic indicator of acute viral hepatitis and cirrhosis of liver

    N. Kaur

    2014-06-01

    Full Text Available Liver disease is a condition that causes liver inflammation or tissue damage and affects liver function. Liver functions tests are abnormal in various liver diseases such as hepatitis, cirrhosis and end stage liver disease. The study of pancreatic enzymes for prognostic purpose in evolving liver disease is gaining ground and act as prognostic indicator for liver diseases. Present study has been planned to assess the serum amylase status in 50 patients of acute viral hepatitis and 50 patients of cirrhosis of liver in comparison to 50 normal healthy control subjects. Levels of serum amylase were determined by CNP- G3 kinetic method. The serum levels of amylase were significantly raised (p<0.0001 in patients compared to control group and levels were observed to be constantly increased with increased severity of liver diseases. The probable cause of variation in serum amylase enzymes in acute viral hepatitis and cirrhosis of liver is its anatomical proximity and common egress system through Ampulla of vater into the duodenum.

    Full Text Available Background: Located in the south western part of Saudi Arabia, the Gizan region is largely a rural community in which hepatitis B and chronic liver disease including hepatocellular carcinoma are highly prevalent. Aim of study: To determine the relative frequencies of acute hepatitis A, B, C and E in acute viral hepatitis in an area of hyperendemic hepatitis B infection. Methods and materials: In a prospective study 246 consecutive patients (179 males and 67 females diagnosed in a 2-year period were tested for markers of Hepatitis A virus (HAV, hepatitis B virus (HBV, hepatitis C (HCV and hepatitis E virus (HEV. Results: Of the patients tested, 131 (53.3% were children (< 10 years, and 42 (17% were 11 - 20 years in age. Ig M anti -HAV, IgM anti-HBV, anti- HCV and IgM anti-HEV were positive in 37%, 19.1%, 3.7% and 13.7% respectively. Markers of these viruses were absent in 24.4%. Among 131 children (< 10 years the commonest cause of AVH was HAV occurring in 57.3% of the cases. In adults (> 21 years HBV was found in 35.6% and IgM anti -HAV was detected in only 6.8%. In contrast to the age- related decline in the frequency of acute HA, the proportion of acute HE were similar in all age groups (13.7% in children, 16.7% in adolescents and 11.0% in adults. Conclusion: The study indicated that HAV is still a common cause of AVH particularly among children in Gizan. Acute 1-113 had a low occurrence among the children, evidently as a consequence of the integration of HB vaccine into the Saudi Arabian national EPI, 10 years ago. With the availability of combined HB and HA vaccines, It should be possible to graft the vaccination against HAV on to the existing program in Saudi Arabia. Affecting 13.4% of the group studied, sporadic HEV constitute a significant cause of AVH in this population. Until HEV vaccine becomes widely available, its prevention would be mainly by the improvement of socio - economic and hygienic standards of the population.

    The association of acute hepatitis E viral (HEV) infection with glucose-6-phosphate dehydrogenase (G6PD) deficiency leading to extensive intravascular haemolysis is a very rare clinical entity. Here we discuss such a patient, who presented with acute HEV illness, developed severe intravascular haemolysis and unusually high levels of bilirubin, complicated by acute renal failure (ARF), and was later on found to have a deficiency of G6PD. The patient recovered completely with haemodialysis and supportive management. PMID:25500531

    WHO estimates reveal that the global prevalence of viral hepatitis may be as high as 500 million, with an annual mortality rate of up to 1.3 million individuals. The majority of this global burden of disease is borne by nations of the developing world with high rates of vertical and iatrogenic transmission of HBV and HCV, as well as poor access to healthcare. In 2013, 3.2% of the global population (231 million individuals) migrated into a new host nation. Migrants predominantly originate from the developing countries of the south, into the developed economies of North America and Western Europe. This mass migration of individuals from areas of high-prevalence of viral hepatitis poses a unique challenge to the healthcare systems of the host nations. Due to a lack of universal standards for screening, vaccination and treatment of viral hepatitis, the burden of chronic liver disease and hepatocellular carcinoma continues to increase among migrant populations globally. Efforts to increase case identification and treatment among migrants have largely been limited to small outreach programs in urban centers, such that the majority of migrants with viral hepatitis continue to remain unaware of their infection. This review summarizes the data on prevalence of viral hepatitis and burden of chronic liver disease among migrants, current standards for screening and treatment of immigrants and refugees, and efforts to improve the identification and treatment of viral hepatitis among migrants.

    2007-01-01

    Our objectives in this study were to compare results obtained by an enzyme immunoassay (EIA) for F-actin antibody (FAA) immunoglobulin G (IgG) to those determined by an indirect fluorescent antibody (IFA) assay for smooth muscle antibody (SMA) IgG, and to determine the prevalence of FAA in patient sera having serologic evidence of acute viral hepatitis. Sera from 415 patients suspected of having autoimmune hepatitis (AIH), 208 patients suspected of having acute viral hepatitis A, B, or C, and 100 healthy blood donors (HBD) were included in the study. Only one of 100 HBD showed low levels (20-30 Units) of F-actin IgG. In patients suspected of having AIH, the prevalence of FAA increased as SMA titers increased and all sera with SMA titers of >or=1:160 were FAA-positive. In contrast, there were many sera with negative (30 Units) of FAA; many exceeding 80 Units. Moreover, 51.4% of these sera were also positive for anti-nuclear antibody (ANA), which is also utilized in diagnosing type 1 AIH. FAA was detected in 25% of viral hepatitis antibody-positive sera, with the majority (59.3%) containing low levels, and all were ANA-negative. PMID:17621360

  17. Serological and Molecular Testing in Viral Hepatitis: An Update

    Weston, Shiobhan R; Martin, Paul

    2001-01-01

    The routine serological diagnoses of the three major forms of viral hepatitis - A, B and C - as well as delta hepatitis, are important in the evaluation of acute and chronic viral hepatitis. Increasingly, molecular virology is also being used to evaluate patients with chronic hepatitis C, with genotype and viral load testing to plan therapy.

    A 29-year-old nurse with a hepatitis C virus (HCV) infection caused by needle-stick injury was treated with interferon-beta starting about one year after the onset of acute hepatitis. The patient developed acute hepatitis C with symptoms of general fatigues, jaundice, and ascites 4 wk after the needle-stick injury. When these symptoms were presented, the patient was pregnant by artificial insemination. She hoped to continue her pregnancy.After delivery, biochemical liver enzyme returned to normal levels. Nevertheless, HCV RNA was positive and the pathological finding indicated a progression to chronicity. The genotype was 1b with low viral load.Daily intravenous injection of interferon-beta at the dosage of six million units was started and continued for eight weeks. HCV was eradicated without severe adverse effects. In acute hepatitis C, delaying therapy is considered to reduce the efficacy but interferon-beta therapy is one of the useful treatments for hepatitis C infection in chronic phase.

  5. The nsp2 replicase proteins of murine hepatitis virus and severe acute respiratory syndrome coronavirus are dispensable for viral replication.

    Graham, Rachel L; Sims, Amy C; Brockway, Sarah M; Baric, Ralph S; Denison, Mark R

    2005-11-01

    The positive-stranded RNA genome of the coronaviruses is translated from ORF1 to yield polyproteins that are proteolytically processed into intermediate and mature nonstructural proteins (nsps). Murine hepatitis virus (MHV) and severe acute respiratory syndrome coronavirus (SARS-CoV) polyproteins incorporate 16 protein domains (nsps), with nsp1 and nsp2 being the most variable among the coronaviruses and having no experimentally confirmed or predicted functions in replication. To determine if nsp2 is essential for viral replication, MHV and SARS-CoV genome RNA was generated with deletions of the nsp2 coding sequence (MHVDeltansp2 and SARSDeltansp2, respectively). Infectious MHVDeltansp2 and SARSDeltansp2 viruses recovered from electroporated cells had 0.5 to 1 log10 reductions in peak titers in single-cycle growth assays, as well as a reduction in viral RNA synthesis that was not specific for any positive-stranded RNA species. The Deltansp2 mutant viruses lacked expression of both nsp2 and an nsp2-nsp3 precursor, but cleaved the engineered chimeric nsp1-nsp3 cleavage site as efficiently as the native nsp1-nsp2 cleavage site. Replication complexes in MHVDeltansp2-infected cells lacked nsp2 but were morphologically indistinguishable from those of wild-type MHV by immunofluorescence. nsp2 expressed in cells by stable retroviral transduction was specifically recruited to viral replication complexes upon infection with MHVDeltansp2. These results demonstrate that while nsp2 of MHV and SARS-CoV is dispensable for viral replication in cell culture, deletion of the nsp2 coding sequence attenuates viral growth and RNA synthesis. These findings also provide a system for the study of determinants of nsp targeting and function. PMID:16227261

    Materials on the organization and realization of prophylactic measures with respect to acute enteric infections (AEI) and viral hepatitis A (VHA) at the period of the liquidation of medico-sanitary consequences of the high flood are presented. As shown in these materials, the epidemiological surveillance on AEI and VHA in the areas affected by the emergency situation included the effective system of monitoring on these diseases. On the basis of monitoring optimum decisions were taken and concrete prophylactic measures were realized. This made it possible to detect the foci of infectious diseases in due time and efficiently liquidate them, as well as to prevent the development of the epidemiological consequences of the high flood.

    2015-01-01

    Acute hepatitis C (HCV) infection has been identified as an important cause of fulminant hepatic failure (FHF), characterized by rapid deterioration of liver function from massive hepatic necrosis leading to encephalopathy and multi-organ failure. We admitted a female patient at Shalamar Hospital with jaundice, fever, encephalopathy and coagulopathy of short duration with no history of any comorbidity. Her hepatitis viral screen revealed positive anti HCV. Her viral loads were also high. A di...

    Hepatic sarcoidosis is usually asymptomatic but rarely leads to adverse liver-related outcome. Co-existence of viral hepatitis and hepatic sarcoidosis is a rare, but recognised phenomenon. Obtaining a balance between immune suppression and anti-viral therapy may be problematic. Immunosuppression in the presence of viral hepatitis can lead to rapid deterioration of liver disease. Similarly, anti-viral therapy may exacerbate granulomatous hepatitis. Here we present two cases of viral hepatitis ...

    2003-01-01

    AIM: To analyze the molecular evolution of different viral genomic regions of HCV in an acute HCV infected patient chronically infected with HIV through a 42-month follow-up.METHODS: Serum samples of a chronically HIV infected patient that seroconverted to anti HCV antibodies were sequenced, from the event of superinfection through a period of 17 months and in a late sample (42nd month). Hypervariable genomic regions of HIV (V3 loop of the gp120) and HCV (HVR-1 on the E2 glycoprotein gene) were studied. In order to analyze genomic regions involved in different biological functions and with the cellular immune response, HCV core and NS5A were also chosen to be sequenced. Amplification of the different regions was done by RT-PCR and directly sequenced. Confirmation of sequences was done on reamplified material. Nucleotide sequences of the different time points were aligned with CLUSTAL W 1.5, and the corresponding amino acid ones were deduced.RESULTS: Hypervariable genomic regions of both viruses (HVR1 and gp120 V3 loop) presented several nonsynonymous changes but, while in the gp120 V3 loop mutations were detected in the sample obtained right after HCV superinfection and maintained throughout, they occurred following a sequential and cumulative pattern in the HVR1. In the NS5A region of HCV, two amino acid changes were detected during the follow-up period, whereas the core region presented several amino acid replacements, once the HCV chronic infection had been established.CONCLUSION: During the HIV-HCV superinfection, each genomic region analyzed shows a different evolutionary pattem.Most of the nucleotide substitutions observed are nonsynonymous and clustered in previously described epitopes,thus suggesting an immune-driven evolutionary process.

  10. An out break of more than 1300 cases of acute viral hepatitis in a tertiary care hospital in Rawalpindi in summer of 2009

    To find out the short-term clinical course including common clinical features, laboratory parameters, treatment provided and outcome of cases of acute viral hepatitis hospitalized in a tertiary care hospital. Study Design: Descriptive observational study. Place and Duration of Study: Military Hospital in Rawalpindi from May to July 2009. Patients and Methods: Patients hospitalized with acute viral hepatitis, both male and female, older than 12 years of age were included in the study. A detailed proforma including patients' particulars, clinical features; laboratory parameters, treatment provided, disposal/ outcome was designed and filled for each patient. Results: During the study period a total 1334 patients were hospitalized, 1279 (95.87%) were male while only 55 (4.13%) were female. Majority of patients were young adults. Mean age was 26 years with a range of 12 to 85 years. Maximum serum bilirubin levels of 559 micromoles and serum alanine aminotransferas (ALT) levels of 7750 IU/L were observed. Maximum prothrombin time (PT) ranged from 105 seconds to failed to clot, against a control of 13 seconds. Thrombocytopenia was observed in some patients especially those with coagulopathy and encephalopathy but recovered with improvement in LFTs. Anti HEV serology was sent in a third of all admitted patients and was positive for IgM in patients tested. Five patients were pregnant ladies. Two patients also had laboratory proven malaria along with acute viral hepatitis. Majority of patients had uneventful recovery. A total of 13 patients went in to hepatic encephalopathy while three unfortunate patients died. Conclusion: HEV has been an important cause of acute viral hepatitis in Pakistan, particularly in adults from lower socioeconomic groups. The problem is more serious for those living in military camps, residential institutions and in segregated areas who consume untreated water from a common source. Outbreaks like the one described have significant morbidity and not

    2016-07-01

    It is of great concern that pregnant women with acute viral hepatitis (AVH) type E have serious consequences. This study aimed to estimate the case-fatality risk (CFR) and potential risk factors of pregnant women with AVH type E. We searched the PubMed, EMBASE, and Web of Science databases for studies containing data on CFR in pregnancy with AVH type E. A pooled estimate of CFR was calculated using a random-effects model. Potential sources of heterogeneity were explored using subgroup analysis, sensitivity analysis, and meta-regression. We identified 47 eligible studies with a total African and Asian population of 3968 individuals. The pooled CFRs of maternal and fetal outcomes were 20·8% [95% confidence interval (CI) 16·6-25·3] and 34·2% (95% CI 26·0-43·0), respectively. Compared with these, the pooled CFR was highest (61·2%) in women with fulminant hepatic failure (FHF). Community-based surveys had lower pooled CFR (12·2%, 95% CI 9·2-15·6) and heterogeneity (25·8%, 95% CI 20·1-32·0) than hospital-based surveys. Univariate analysis showed that hospital-based surveying (P = 0·007), and patients in the third trimester of pregnancy or with FHF (P < 0·05), were significantly associated with CFR. Intrauterine fetal mortality (27·0%) was statistically higher than neonatal mortality (3·9%). Control measures for HEV infection would reduce feto-maternal mortality in Asia and Africa.

    Alcohol consumption is often associated with viral hepatitis. Although alcohol is known to worsen viral liver disease, the interactions between alcohol and viral hepatitis are not fully understood. Molecular alterations in the liver due to alcohol and viral hepatitis include effects on viral replication, increased oxidative stress, cytotoxicity, and a weakened immune response. Clinically, alcohol enhances disease progression and favors induction of primitive liver neoplasm. The use of new ant...

    2015-11-01

    Liver inflammation or hepatitis has many different causes, both infectious and non-infectious. Among the former, viral infection is responsible for at least half of all hepatitis worldwide. Different viruses have been described with primary tropism for liver tissue. These microorganisms have been successively named with letters of the alphabet: A, B, C, D, E and G. The aim of this paper is to review this heterogeneous group of viruses in its most basic aspects, including clinical implications, treatment, main control, and prophylactic measures and, of special interest, diagnostic approaches, both serological and molecular, which are used for their detection, quantification and characterization.

  17. Acute hepatitis C: Prospects and challenges

    2007-01-01

    More than 170 million people worldwide have chronic hepatitis C. Acute hepatitis C is rarely diagnosed because it is commonly asymptomatic. Most infected patients are unaware of their condition until the symptoms of chronic infection manifest. Treatment of acute hepatitis C is something of a paradox because spontaneous resolution is possible and many patients do not have symptoms.However, several factors provide a rationale for treating patients who have acute hepatitis C. Compared with acute hepatitis C, chronic hepatitis C is associated with a worse prognosis, the need for more intensive treatment,longer treatment duration, and a decrease in successful treatment outcomes. Conversely, early intervention is associated with improved viral eradication, using a regimen that is better tolerated, less expensive, more convenient, and of shorter duration than the currently approved combination therapies for chronic hepatitis C.

    1993-01-01

    The most reliable method of making a specific aetiological diagnosis of chronic viral hepatitis would be to identify virus specific cytotoxic T lymphocytes responsible for the killing of virus infected hepatocytes in each patient's liver. Unfortunately, this can not be proposed for routine diagnosis and surrogate tests are required. The detection of virus markers, and even of the virus itself, does not imply that liver damage is caused by virus infection. Indirect markers of the host's antivi...

    Full Text Available Acute pancreatitis complicating fulminant viral hepatitis has been well recognized; however, acute pancreatitis occurring in nonfulminant hepatitis is very rare. The case presented describes moderate pancreatitis in a young male, manifesting during the course of nonfulminant acute hepatitis E infection. The diagnosis of acute viral hepatitis E was confirmed by serology and reverse transcriptase polymerase chain reaction (RT-PCR to demonstrate Hepatitis E virus (HEV RNA in both stool and serum. Patients with acute viral hepatitis presenting with severe abdominal pain should have a diagnosis of acute pancreatitis suspected and appropriate investigations including serum amylase, lipase, biliary ultrasonography and/or contrast-enhanced computed tomography of the abdomen should be undertaken. The identification of this unusual complication of Hepatitis E is important; however, the prognosis for patients with Acute Pancreatitis Complicating Acute Hepatitis E Virus Infection is good, and uncomplicated recovery with conservative treatment is expected.

    2012-01-01

    The present study aims to evaluate the anti-HCV activity of hotwater extract from Platycodon grandiflorum (BC703) with HCV genotype 1b subgenomic replicon system and investigate its hepatoprotective activity on carbon tetrachloride (CCl(4))-induced acute liver damage in mice. BC703 produced significant hepatoprotective effects against CCl(4)-induced acute hepatic injury by decreasing the activities of serum enzymes, nitric oxide and lipid peroxidation. Histopathological studies further substantiated the protective effect of BC703. Furthermore, BC703 inhibited the HCV RNA replication with an EC(50) value and selective index (CC(50)/EC(50)) of 2.82 µg/mL and above 35.46, respectively. However, digested BC703 using a simulated gastric juice showed poor protective effect against CCl(4)-induced hepatotoxicity in mice and decreased anti-HCV activity as compared to the intact BC703. Although further studies are necessary, BC703 may be a beneficial agent for the management of acute hepatic injury and chronic HCV infection. PMID:22878389

  5. The epidemiology of viral hepatitis in Qatar

    Bener Abdulbari

    2009-01-01

    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.

  6. Complement levels in acute infectious hepatitis and serum hepatitis

    Kosmidis, J. C.; Leader-Williams, Lesley K.

    1972-01-01

    The level of the third component of complement was measured in serial specimens of serum taken from thirty-one patients with acute viral hepatitis. Fourteen of the thirty-one patients were positive for the hepatitis-associated antigen. A characteristic fluctuation was observed in twenty-nine of the thirty-one patients. This consisted of an initial fall of the level of C3, followed by an increase to a higher than normal level and then a gradual return to normal. No difference was observed between the patients who were positive and those who were negative for the hepatitis-associated antigen. These results support the view that immune complexes play a significant role in the pathogenesis of acute viral hepatitis. PMID:4624985

    Patient records from the Guam Cancer Registry were compared with patients listed in a health department viral hepatitis case registry. The number of liver cancer and viral hepatitis cases were compared by ethnicity. Hepatitis C was the form of viral hepatitis most common among liver cancer cases on Guam (63.3% of viral hepatitis-associated liver cancer cases). Since viral hepatitis is an important cause of liver cancer, studies such as the present one may provide the information necessary to ...

  8. A review of hepatitis viral infections in Pakistan

    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

    AIM: To elucidate the frequency and characteristics of pancreatic disorders in the course of chronic viral hepatitis. METHODS: We prospectively assessed the serum pancreatic enzyme levels and imaging findings in patients with chronic viral hepatitis and healthy control subjects. RESULTS: Serum amylase (t-Amy), salivary amylase (s-Amy), pancreatic amylase (p-Amy) and serum lipase levels were higher in hepatitis patients in comparison to control subjects. However, in asymptomatic viral carriers, only the serum t-Amy levels were higher than those of the controls. The levels of each enzyme rose with the progression of liver disease in patients with hepatitis B or C; whereas the levels of each enzyme within the same clinical stage of the disease did not differ between patients diagnosed with either hepatitis B or hepatitis C virus. Imaging findings demonstrated chronic pancreatitis in only 1 out of 202 patients (0.5%).CONCLUSION: Our data suggest that serum levels of pancreatic enzymes increase with the progression of liver disease in patients diagnosed with viral hepatitis. Pancreatic disease, asymptomatic in most cases, may represent an extrahepatic manifestation of chronic viral hepatitis.

  11. Clinical study of hepatitis in children with special reference to viral markers.

    Zankhana Parekh

    2013-01-01

    Full Text Available nfective hepatitis is a systemic viral infection marked by hepatic cell necrosis and hepatic inflammation which leads to a characteristic constellation of clinical, biochemical and histological changes. This exercise was done to study the epidemiology of infective hepatitis, presenting symptoms and signs, mode of transmission, complication and outcome and to study the role of various investigations with special focus on viral markers. We concluded that poor outcome related with viral hepatitis in children were HBsAg reactivity, higher SGPT and serum bilirubin levels, higher PT levels and development of encephalopathy. Anti HAV and anti HEV IgM markers are very sensitive test for diagnosing acute infection.

  12. [Treatment for viral hepatitis in institutionalized individuals].

    Horvat, Jadranka

    2009-12-01

    The presence and spread of viral hepatitis infection in the prison population is much higher than in the general population. Prisoners represent a combination of several high risk subpopulations and are therefore generally considered a high risk category. When outside the prison system, members of these high risk groups are generally not available for education, prevention and therapy. While within the prison system, they are available for systematic and continuing monitoring and therapy. This includes testing of their HBV, HCV and HIV status. Due to the high incidence of viral hepatitis in the prison population and based on the results of a study from 2007, we established the Prison System Viral Hepatitis Counseling Center. The Center operates within the internal ward of the Prison Hospital. Currently, 42 patients are treated for chronic hepatitis C. The Center's Plan and Operating Program and treatment results are presented. PMID:20198905

  14. DNA-guided hepatitis B treatment: Viral load is insufficient with few exceptions

    Pankaj Jain

    2009-01-01

    In DNA-guided hepatitis B treatment, viral load is insufficient, and requires other viral markers for treatment of hepatitis B patients as in patients with acute exacerbation of chronic hepatitis B, end-stage renal disease on dialysis, human immunodeficiency virus co-infected patients. There are exceptions to this rule:a residual level hepatitis B virus (HBV) DNA at 24 wk predicts beneficial outcome and reduced resistance at 1 year. The genotypic viral resistance to antiviral agents and occult HBV infection can be determined by HBV-DNA levels.

  18. Viral hepatitis: a sexually transmitted disease?

    Buzby, M

    1996-03-01

    Sexually transmitted diseases (STDs) are often discussed in the context of herpes, gonorrhea, chlamydia, and AIDS. Viral hepatitis, specifically hepatitis B, is also an STD often omitted from these discussions. The incidence of hepatitis B virus (HBV) is variable throughout the world. In North America, the highest incidence occurs in patients who are between the ages of 15 and 25 years. Safe and effective vaccines are available to prevent HBV infection, which has an associated increased risk of chronic liver disease and hepatocellular carcinoma in the carrier state. Hepatitis C virus (HCV) is a newly identified hepatotrophic virus that may also be sexually transmitted. There are no vaccines for the prevention of HCV infection and the majority of those who are infected become chronic carriers with chronic liver disease. Discussions focused on the prevention of STDs must include counseling for the prevention of HBV and HCV. PMID:8788658

    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.

    1980-01-01

    To determine the diagnostic value of hepatitis B core (HBc)-specific immunoglobulin M (IgM) antibody (anti-HBc IgM), the sera of six patients with known recent acute viral hepatitis B were examined for the presence of anti-HBc periodically for up to 21 months from the onset of the attack by a sensitive radioimmunoassay technique (CORAB, Abbott Laboratories). It was found that anti-HBc IgM was detectable for approximately 17 months from the onset of the illness. Hence the finding of anti-HBc I...

    The patient was a 57-year-old woman presenting with jaundice as the chief complaint. She began vomiting on July 10, 2003.Jaundice was noted and admitted to our hospital for thorough testing. Tests on admission indicated severe hepatitis, based on: aspartate aminotransferase (AST), 1 076 IU/L; alanine aminotransferase (ALT), 1 400 IU/L; total bilirubin (TB), 20.9 mg/dL; and prothrombin time rate (PT%), 46.9%. Acute hepatitis A (HA) was diagnosed based on negative hepatitis B surface antigen and hepatitis C virus RNA and positive immunoglobulin (Ig) M HA antibody, but elevation of anti-nuclear antigen (×320) and IgG (3 112 mg/dL) led to suspicion of autoimmune hepatitis (AIH). Plasma exchange was performed for 3 d from July 17, and steroid pulse therapy was performed for 3 d starting on July 18, followed by oral steroid therapy. Liver biopsy was performed on August 5, and the results confirmed acute hepatitis and mild chronic inflammation. Levels of AST and ALT normalized,so dose of oral steroid was markedly reduced. Steroid therapy was terminated after 4 mo, as the patient had glaucoma. Starting 3 mo after cessation of steroid therapy,levels of AST and ALT began to increase again. Another liver biopsy was performed and AIH was diagnosed based on serum data and biopsy specimen. Oral steroid therapy was reinitiated. Levels of AST and ALT again normalized.The present case was thus considered to represent AIH triggered by acute HA.

  4. Viral Hepatitis in Renal Transplant Patients

    Bernieh Bassam

    1999-01-01

    Full Text Available Hepatitis is emerging as a common serious problem in renal transplant patients. To determine the prevalence of viral hepatic in our transplant population, we screened the patients who received renal transplants in the period from 1979-1997, inclusive, for hepatitis B virus (HBV and for hepatitis C virus (HCV infection. Of those patients screened for HBV infection, seven o f101 recipients (6.9% were found positive for HbsAg. During the follow up, one patient cleared HbsAg and one from the negative group acquired it. Of the recipients screened for HCV antibodies 32 of 78 patients (41% had positive tests. Higher incidence of chronic liver disease (37.5% was found in the HCV positive group, compared to zero in the negative group. However, no difference in the short-term graft loss (25%, was noted between these two groups. We conclude that prevalence of hepatitis C in our transplant patients is high and may have an impact on their long-term outcome.

    2011-07-01

    The aim of this study was to examine the contribution of hepatitis B virus (HBV) and hepatitis C virus (HCV) to pregnancy-related complications including gestational diabetes mellitus (GDM), preterm birth (PTB), intrauterine growth restriction (IUGR), pre-eclampsia, antepartum haemorrhage and cholestasis. The Nationwide Inpatient Sample was queried for all pregnancy-related discharges, pregnancy complications and viral hepatitis from 1995 to 2005. Logistic regression was used to examine the association between HBV, HCV, HBV + HCV and pregnancy-related complications including GDM, PTB, IUGR, pre-eclampsia, antepartum haemorrhage, cholestasis and caesarean delivery. Model covariates included maternal age, race, insurance status, substance use and medical complications including liver complication, hypertension, HIV, anaemia, thrombocytopenia and sexually transmitted infections. Of 297 664 pregnant women data available for analysis, 1446 had a coded diagnosis of HBV, HCV or both. High-risk behaviours, such as smoking, alcohol and substance use were higher in women with either HBV or HCV. Women with HBV had an increased risk for PTB (aOR 1.65, CI [1.3, 2.0]) but a decreased risk for caesarean delivery (aOR 0.686, CI [0.53, 0.88]). Individuals with HCV had an increased risk for GDM (aOR 1.6, CI [1.0, 2.6]). Individuals with both HBV and HCV co-infection had an increased risk for antepartum haemorrhage (aOR 2.82, CI [1.1, 7.2]). There was no association of viral hepatitis with IUGR or pre-eclampsia. Women with hepatitis have an increased risk for complications during pregnancy. Research to determine the efficacy and cost-effectiveness of counselling patients about potential risks for adverse outcomes is warranted. PMID:21692952

  8. The Management of Chronic Viral Hepatitis: A Canadian Consensus Conference 2004

    Morris Sherman

    2004-01-01

    Full Text Available Several government and nongovernment organizations held a consensus conference on the management of acute and chronic viral hepatitis to update previous management recommendations. The conference became necessary because of the introduction of new forms of therapy for both hepatitis B and hepatitis C. The conference issued recommendations on the investigation and management of chronic hepatitis B, including the use of lamivudine, adefovir and interferon. The treatment of hepatitis B in several special situations was also discussed. There were also recommendations on the investigation and treatment of chronic hepatitis C and hepatitis C-HIV coinfection. In addition, the document makes some recommendations about the provision of services by provincial governments to facilitate the delivery of care to patients with hepatitis virus infection. The present document is meant to be used by practitioners and other health care providers, including public health staff and others not directly involved in patient care.

  9. Case of acute hepatitis E with concomitant signs of autoimmunity

    Catarina Lima Vieira

    2013-01-01

    Full Text Available Sporadic cases of acute viral hepatitis E have been described in developed countries, despite the more common occurrence in endemic areas and developing countries. We present the case of a 58 years old Portuguese female, with no epidemiological relevant factors, admitted with acute hepatitis with positive anti-nuclear antibodies, anti-smooth muscle antibody and high serum gamma globulin (> 1.5 fold increase. Serologies for hepatitis A virus, hepatitis B virus, hepatitis C virus, Epstein-Barr virus, cytomegalovirus, hereditary sensory neuropathy and varicella zoster virus were negative. Liver biopsy histology revealed changes compatible with autoimmune hepatitis. Prednisolone and azathioprine was started. She tested positive for immunoglobulin M anti hepatitis E virus (HEV with detectable viremia by reverse transcription polymerase chain reaction (RT-PCR technique. HEV-RNA was confirmed through RT-PCR in a liver specimen, establishing the diagnosis of acute hepatitis E. Immunosuppression was stopped. She clinically improved, with resolution of laboratory abnormalities. Therefore, we confirmed acute hepatitis E as the diagnosis. We review the literature to elucidate about HEV infection and its autoimmune effects.

    2009-06-01

    Full Text Available Brucella infection is a systemic disease. It rarely causes local infections like hepatitis in gastrointestinal system. In this article we would like to present an acute hepatitis case related to brucella infection that followed up in our clinic. A male, 30 year-old patient hospitalized due to common muscle pain, high fever and vomiting. During the physical examination the patient’s skin, scleras and mucosal membranes were icteric, the liver was 2-3 cm palpable and tender. Laboratory findings were as follows: AST:1190 U/L; ALT:715 U/L; GGT:961 U/L; ALP:369 U/L; total bilirubin:4.6 mg/dL; direct bilirubin:2.1 mg/dL. Viral markers were found to be negative. We started treatment with streptomicine and doxicycline since, the patient’s standard brucella tube agglutination test was positive (1/60 and brucella spp produced in his blood culture. From the second day of the treatment, we started to get clinical response. On the 17th day of the treatment, he discharged from the hospital because ALT, AST and bilirubine level were found normal and his treatment was completed to the 8 weeks. Brucella is continuing to be an important health problem especially who live in surrounding countryside and have to keep in mind in the differential diagnosis of the acute hepatitis.

  14. Overview of hepatitis B viral replication and genetic variability.

    Tong, Shuping; Revill, Peter

    2016-04-01

    Chronic infection with hepatitis B virus (HBV) greatly increases the risk for liver cirrhosis and hepatocellular carcinoma (HCC). HBV isolates worldwide can be divided into ten genotypes. Moreover, the immune clearance phase selects for mutations in different parts of the viral genome. The outcome of HBV infection is shaped by the complex interplay of the mode of transmission, host genetic factors, viral genotype and adaptive mutations, as well as environmental factors. Core promoter mutations and mutations abolishing hepatitis B e antigen (HBeAg) expression have been implicated in acute liver failure, while genotypes B, C, subgenotype A1, core promoter mutations, preS deletions, C-terminal truncation of envelope proteins, and spliced pregenomic RNA are associated with HCC development. Our efforts to treat and prevent HBV infection are hampered by the emergence of drug resistant mutants and vaccine escape mutants. This paper provides an overview of the HBV life cycle, followed by review of HBV genotypes and mutants in terms of their biological properties and clinical significance. PMID:27084035

  19. Management issues in chronic viral hepatitis: hepatitis C.

    Sievert, William

    2002-04-01

    The natural history of chronic hepatitis C virus (HCV) infection and intervention with antiviral therapy are closely linked issues that cause the greatest controversy and concern for the person infected with HCV, as well as for the clinician involved in the assessment and treatment of people with chronic HCV infection. The outstanding challenge of natural history is to identify the person who is likely to develop serious liver disease, and to make that determination early in the course of chronic HCV infection when treatment is likely to be of the greatest benefit. Significant advances in the therapy of chronic HCV infection have occurred over the past decade. A sustained virological response (SVR), defined as undetectable HCV-RNA in blood 6 months after completing antiviral treatment, is the best indicator of a beneficial treatment effect. Relapse, breakthrough or non-response should all be regarded as unsuccessful outcomes of therapy. Interferons are still the mainstay of antiviral therapy for chronic HCV infection. The combination of interferon and ribavirin has improved SVR by decreasing the relapse rate. Treatment responses vary according to host factors such as age and gender, fibrotic severity and to viral factors like genotype and viral load. Patients with genotype 1 HCV and a high viral load require 12 months of treatment to achieve a SVR in approximately 30%, compared to those with genotypes 2 or 3 who achieve a SVR in approximately 65% after 6 months. Patients who relapse after an end-of-treatment response to interferon monotherapy have a good chance of responding to combination interferon and ribavirin given for 6 months, but a longer treatment course should be considered in less optimal cases. At present, the treatment of those with non-response is less clear, but there is interest in more intense forms of interferon therapy, such as induction dosing or pegylated interferon in combination with ribavirin. Clinicians need to be aware of the common side

  20. Acute hepatitis with nontyphoidal salmonella and hepatitis E virus coinfection

    2014-09-01

    Full Text Available A 65-year-old Taiwanese man presented with dark urine for 5 days before admission to hospital and with fever on the 2nd day of admission to hospital. Laboratory studies showed acute hepatitis with hyperbilirubinemia. Acute hepatitis with nontyphoidal salmonella and hepatitis E virus coinfection was diagnosed. The fever subsided after treatment with ceftriaxone and cefepime. His serum bilirubin reached its peak value on the 3rd week after admission to hospital and then gradually returned to the normal range. To the best of our knowledge, acute hepatitis E coinfection with nontyphoidal salmonella has not been reported previously.

  1. Hepatic transcriptome analysis of hepatitis C virus infection in chimpanzees defines unique gene expression patterns associated with viral clearance.

    Santosh Nanda

    Full Text Available Hepatitis C virus infection leads to a high rate of chronicity. Mechanisms of viral clearance and persistence are still poorly understood. In this study, hepatic gene expression analysis was performed to identify any molecular signature associated with the outcome of hepatitis C virus (HCV infection in chimpanzees. Acutely HCV-infected chimpanzees with self-limited infection or progression to chronicity were studied. Interferon stimulated genes were induced irrespective of the outcome of infection. Early induction of a set of genes associated with cell proliferation and immune activation was associated with subsequent viral clearance. Specifically, two of the genes: interleukin binding factor 3 (ILF3 and cytotoxic granule-associated RNA binding protein (TIA1, associated with robust T-cell response, were highly induced early in chimpanzees with self-limited infection. Up-regulation of genes associated with CD8+ T cell response was evident only during the clearance phase of the acute self-limited infection. The induction of these genes may represent an initial response of cellular injury and proliferation that successfully translates to a "danger signal" leading to induction of adaptive immunity to control viral infection. This primary difference in hepatic gene expression between self-limited and chronic infections supports the concept that successful activation of HCV-specific T-cell response is critical in clearance of acute HCV infection.

  4. Markers of viral hepatitis in hemophiliacs

    Sero prevalence of Hepatitis B surface antigen (HbsAg) and anti-HCV IgG was determined in 100 persons with Hemophilia (PWH), registered with Hemophilia Patient Welfare Society (HPWS), Lahore Zone, Pakistan. The study shows that 4% were positive for HBsAg. However, there was a high level of anti-HCV sero positivity (56%) in our PWH, including many patients in younger age groups. When compared with figures from PWH in other regions of Asia like 23% in Western India, 33% in Sri Lanka and 15% of those in Iran, this figure is one of the highest. This rate is a reflection of the same rising trend in our population that is now exceeding 10%. The practice of unscreened blood/blood-products transfusions in the backdrop of high prevalence of HCV in our population is responsible for high figures seen in PWH. The need is to increase awareness amongst the patients, health care workers and policy makers about the transfusion associated viral infections in a group of patients who already had a hereditary disorder of severe nature.

  5. [From the national competence network for viral hepatitis (HepNet) emerged the German Liver Foundation (Deutsche Leberstiftung)].

    Hardtke, S; Wiebner, B; Manns, M P

    2016-04-01

    The competence network for viral hepatitis (HepNet) was founded in 2002 with funding from the German government and has influenced the research on viral hepatitis in Germany. HepNet collaborator sites have been involved in numerous national and international investigator-initiated, as well as industry-sponsored, phase 1-3 studies. Within the HepNet Study-House, many groundbreaking investor-initiated trials have been completed and are still ongoing. For example, the acute hepatitis C trials and trials on chronic hepatitis D (delta), which led to therapy optimization. Continuation of the competence network on viral hepatitis has been achieved by the foundation of the German Liver Foundation, which has been an external cooperation partner of the German Center for Infection Research (DZIF) for two years. The well-established HepNet Study-House acts here as the clinical trial platform for all DZIF hepatitis trials. PMID:26942931

    Full Text Available A 35-year-old man was referred to our center because of low grade fever, vomiting, yellow sclera, and tenderness in the upper-right quadrant of his abdomen. Laboratory tests showed a white blood cell (WBC of 7100/µL, a platelet of 184,000/µL, an erythrocyte sedimentation rate (ESR of 4 mm/h, an alanine aminotransferase (ALT of 525 U/L, an aspartate aminotransferase AST of 142 U/L, a total bilirubin level of 4.23 mg/dL, and a direct bilirubin level of 3.16 mg/dL. Viral hepatitis markers, immunoglobuline M antibody to cytomegalovirus (anti-CMV IgM, Ebstein-Barr virus (EBV IgM, and immunologic markers of autoimmune hepatitis were negative. The patient was diagnosed with acute hepatitis. Alkaline phosphatase was in the normal range throughout the course of the disease. Because of the patient's occupation as a butcher and his history of eating semi-cooked sheep testes, serologic tests of brucellosis were conducted; the tests came out positive. We were concerned about the hepatotoxicity of standard regimens; therefore, we started treatment with streptomycin and ciprofloxacin regimens. Although liver enzyme had fallen and fever discontinued, the total and direct bilirubin concentrations in the patient's serum both increased in spite of using 2 weeks of the abovementioned drug regimen. The elevation of bilirubin could have been due to drug hepatotoxicity. Alternatively, a regimen containing ciprofloxacin may have not have been efficient enough and may have had effects on the direct bilirubin concentration. Fortunately, within 8 weeks, progressive recovery was noticed. Brucellosis should be considered in the differential diagnosis of fever and hepatitis for those who live in endemic areas, especially if his/her job was at high risk for acquiring brucellosis. We recommend taking a careful occupational and behavioral history for patients with acute hepatitis syndrome. We assumed that ciprofloxacin was not suitable for brucella hepatitis treatment and

    2012-01-01

    Extraordinary viral sequence diversity and rapid viral genetic evolution are hallmarks of hepatitis C virus (HCV) infection. Viral sequence evolution has previously been shown to mediate escape from cytotoxic T-lymphocyte (CTL) and neutralizing antibody responses in acute HCV infection. HCV evolution continues during chronic infection, but the pressures driving these changes are poorly defined. We analyzed plasma virus sequence evolution in 5.2-kb hemigenomes from multiple longitudinal time p...

  12. Regulatory mechanisms of viral hepatitis B and C

    G Waris; A Siddiqui

    2003-04-01

    Of all the hepatitis viruses, only the hepatitis B virus (HBV) and hepatitis C virus (HCV) cause chronic hepatitis, which can progress to cirrhosis and hepatocellular carcinoma. In this review, we discuss how these two biologically diverse viruses use common pathways to induce oxidative stress and activation of key transcription factors, known to be involved in inflammatory processes in cells. Activation of NF-B and STAT-3 most likely contribute to the progression of viral infections to chronic hepatitis and liver oncogenesis associated with HBV and HCV infections. In this review, we focus on the mechanisms of action of HBx and HCV NS5A proteins in inducing intracellular events associated with the viral infections.

    2015-12-01

    Full Text Available Hepatitis A is an acute infectious disease of the liver caused by the hepatitis A virus. Many cases have little or no symptoms. In our case, a nineteen year old female patient referred our hospital because of exhaustion, jaundice and diffuse itching complaints which existed for one week. In dermatological examination, there were diffusely erythematous, excoriated papules with crusts on the body as more significant on the lower extremity. The patient was diagnosed with acute viral hepatitis A and generalized pruritus according to present findings. Cholestyramine 16 g/day and acrivastine tablet as 1x1 were started to administrate for hyperbilirubinemia and itching. The patient whose complaints regressed partially at the eighth day of the treatment was discharged by her own will. Consequently, patients with generalized pruritus who do not have any previous primary cutaneous disorders could be tested for HAV infection. J Microbiol Infect Dis 2015;5(4: 184-186

  16. Studies on some biochemical parameters in viral hepatitis patients

    The present investigation deals with studying liver amino transferases (ALT. AST). Cholesterol and triglycerides. As well as testosterone and protection hormones in blood of Egyptian men infected with hepatitis C virus.hepatitis B virus and mixed B and C viruses. These biochemical parameters were evaluated to be used in diagnosis and prognosis of viral hepatitis. Which considered the most important health problem in Egypt and developing countries. Biochemical analysis were performed using spectrophotometric and radioimmunoassay techniques. All data will be subjected to statistical analysis in order to detect the most suitable biochemical analysis that can be used as specific tests for early diagnosis of viral hepatitis and to detect the parameters that show abnormalities among the different groups of infected patients. The data revealed that AST and ALT levels were increased in all patient groups. Concerning the level of triglycerides, it was increased only in the group of mixed viral hepatitis B and C, while cholesterol showed non-significant changes in all viral hepatitis groups. The sex hormone testosterone was decreased in all infected patients while the prolactin level was increased only in case of patients infected with mixed B and C viruses. However, these abnormal values in such sex hormones play a serious role in male sterility

  17. Viral Hepatitis and Diabetes: Clinical Implications of Diabetes Prevention Through Hepatitis Vaccination.

    Karnchanasorn, Rudruidee; Ou, Horng-Yih; Lin, James; Chuang, Lee-Ming; Chiu, Ken C

    2016-10-01

    Viral hepatitis has been posited to play a role in the development of type 2 diabetes. Thus, prevention of viral hepatitis through vaccination has the potential to reduce the burden of type 2 diabetes. We have shown that successful hepatitis B vaccination reduces the risk of diabetes by 33 %. Although diabetes can be prevented by behavior modification and pharmaceutical agents, these require significant personal commitment and cost. In contrast, diabetes prevention through hepatitis B vaccination would require little personal commitment and relatively low cost. In this review, we discuss hepatitis viruses A, B, and C and their interaction with diabetes; explore the potential underlying mechanisms and potential for hepatitis vaccination to reduce diabetes; and estimate the medical expense savings that would result from such an intervention. Given the projected increase of diabetes prevalence in the developing regions, where hepatitis B is endemic, exploration of such an intervention is very timely. PMID:27620495

  18. The incidence of sporadic viral hepatitis in North India:a preliminary study

    Subrat Kumar; Radha Kanta Ratho; Yogesh Kumar Chawla; India

    2007-01-01

    BACKGROUND:Viral hepatitis is one of the major causes of mortality and morbidity in developing countries. Hepatitis E virus (HEV) among the major etiological agents is responsible for both sporadic and epidemic outbreaks. The epidemic outbreak is water-borne whereas the sporadic outbreak is possibly through contact. Various diagnostic tools at times fail to pinpoint the cause of viral hepatitis. This study was carried out to evaluate the utility of ELISA and nRT-PCR (nested reverse transcriptase polymerase chain reaction) for the diagnosis of sporadic and acute viral hepatitis (AVH) caused by HEV in an endemic situation in North India. METHODS:Serum samples were collected from all the affected and suspected persons and subjected to serological detection of HAV IgM, HBsAg, HCV antibody and HEV IgM. The samples that were positive for HEV IgM were further processed for the detection of HEV RNA by nRT-PCR. RESULTS:A total of 843 samples were collected from 685 patients with AVH, 70 patients with fulminant hepatic failure (FHF), 53 patients with chronic liver disease (CLD), 11 patients with antituberculosis therapy (ATT)-induced jaundice, and 24 pregnant women. The percentage of positivity for anti-HEV IgM was 58.3% in the pregnant women, 41.4% in the paients with FHF, 38.6% in the patients with AVH, 9.4% in the patients with CLD and 18.2% in the patients with ATT induced jaundice. 9.4%of HBsAg carriers were positive for anti-HEV IgM. Males outnumbered females (62.8% vs. 37.1%). Furthermore, the rates of fulminant and acute outbreaks of hepatitis with HEV RNA positivity were 41.4% and 9.4%, respectively. CONCLUSION:Serological and molecular analysis should be combined for the diagnosis of viral infections, especially in endemic areas.

  19. Aptamers Against Viral Hepatitis: from Rational Design to Practical Application

    Hui FENG; Kang-hong HU

    2008-01-01

    Aptamers are short nucleic acids or peptides that strongly bind to a protein of interest and functionally inhibit a given target protein at the intracellular level. Besides high affinity and specificity, aptamers have several advantages over traditional antibodies. Hence, they have been broadly selected to develop antiviral agents for therapeutic applications against hepatitis B and C viruses (HBV, HCV). This review provides a summary of in vitro selection and characterization of aptamers against viral hepatitis, which is of practical significance in drug discovery.

  20. Tissue viral load variability in chronic hepatitis C.

    Fanning, L

    2012-02-03

    OBJECTIVE: Liver biopsy is regarded as the gold standard for assessing disease activity in chronic hepatitis C, but sampling error is a potential limitation. Whether sampling variability applies equally to viral load assessment as it does to histology is uncertain. To examine this, we compared viral load between right- and left-lobe biopsy specimens from patients infected with hepatitis C virus (HCV). METHODS: Bilobe biopsies were taken from 16 patients who were serum positive for HCV RNA by reverse transcription-polymerase chain reaction. Genotype was identified by reverse line probe hybridization. There was an absence of competing risk factors for infectious and other liver diseases in this patient group. Histology and hepatic viral load were assessed blindly. None of the patients had received antiviral therapy at the time of study. RESULTS: Detection of HCV in right and left lobes was concordant with serum positivity in all cases. The viral load between lobes was highly correlated (p = 0.0003, r = 0.79). In contrast, the histological activity indices of inflammation and fibrosis\\/cirrhosis were poorly correlated between lobes (p = 0.038, r = 0.60, and p = 0.098, r = 0.50, respectively). CONCLUSION: Hepatic viral load variability does not suffer from the same degree of heterogeneity of sampling variability as does histology.

    Full Text Available Michael Mirmanesh,1 Quoc-Sy Nguyen,1 Alexey Markelov2 1Drexel University College of Medicine, Philadelphia, PA, USA; 2Department of Surgery, Easton Hospital, Easton, PA, USA Introduction: Hepatic portal venous gas is the presence of gas within the portal venous system that can result from a variety of insults to the gastrointestinal system, and which may be a diagnostic clue to ominous abdominal pathologies, such as acute bowel ischemia or necrosis. Case: We report a case of a 71-year-old man with acute onset abdominal pain whose initial radiologic testing showed extensive portal venous gas. The patient was managed conservatively with resolution of portal venous gas on day 2 of hospitalization. The findings were consistent with a final diagnosis of hepatic portal venous gas caused by viral gastroenteritis. Conclusion: History and physical examination along with presenting signs and symptoms, in conjunction with imaging studies, are vital to delineate the cause of hepatic portal venous gas. In the absence of alarming signs and symptoms, hepatic portal venous gas can be conservatively managed without the need for invasive surgical exploration. Keywords: hepatic portal venous gas, portal venous gas, portal venous air, hepatic venous gas, hepatic venous air, gastroenteritis

  4. Fetomaternal Outcome in Acute Hepatitis E

    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)

    Sánchez-Quijano, Armando; Lissen-Otero, Eduardo

    2006-10-01

    Hepatitis C virus infection is the principal cause of chronic liver disease, cirrhosis and hepatocellular carcinoma in the Western World. Chronic hepatitis C is often silent, most of the times discovered only by routine serologic or biochemical testing and the interval between infection and the development of cirrhosis exceed 30 years. Interestingly the complications of chronic hepatitis C virus infection can be prevented by antiviral therapy. At present, the combination of pegylated interferon-alfa and ribavirina has become the standard treatment of chronic hepatitis C. The management of HCV infection in "special populations" (HIV coinfection and HCV therapy-experienced patient) has improved significantly over the past few years, through a better knowledge of the disease and the publication of several clinical trials performed in these patients. At presents, a number of new anti-HCV therapies are in development. Future drugs for HCV infection might make possible to eradicate HCV in future. PMID:16987471

    Hepatitis E infection is usually a self-limiting disease. In industrialized countries, sporadic cases of acute hepatitis E virus (HEV) infections have been described; their number seems to be increasing in European countries. We report the first human case of autochthonous acute hepatitis E confirmed in Portugal. Patients with acute non-A-C hepatitis should be tested for HEV in Portugal and hepatitis E infection should be considered in the differential diagnosis of unexplained hepatitis cases.

  11. [Amniocentesis and viral risk (hepatitis B, C virus and HIV)].

    Ducarme, G; Ceccaldi, P-F; Bernuau, J; Luton, D

    2009-10-01

    Very few studies have properly addressed to the risk of fetal hepatitis B (HBV), hepatitis C (HCV) or human immunodeficiency virus (HIV) infection through amniocentesis. For HBV, this risk is low. However, knowledge of the maternal hepatitis B e antigen status is valuable in the counselling of risks associated with amniocentesis. For HCV, the risk is not well known but cannot be excluded. For HIV, it seems rational to propose a viral test before amniocentesis for patients with contamination's risk and to postpone the sampling in cases with positive results in order to obtain an undetectable HIV-1 RNA viral load. For these reasons, it can be useful to analyse for each virus the benefit of amniocentesis and the risk of mother-to-infant transmission, and to inform the patient. PMID:19679409

    Charlton, B R; Barr, B C; Castro, A E; Davis, P L; Reynolds, B J

    1990-01-01

    Herpesvirus infection was diagnosed in a toucan. The herpesvirus was isolated from the liver and identified by electron microscopy in the liver and in cell culture. A negative immunofluorescent reaction was obtained when virus-infected cell cultures were reacted with a conjugate to the herpesvirus of Pacheco's disease. The main pathologic finding in the toucan consisted of a severe necrotizing hepatitis with intranuclear inclusions in the liver and spleen. A presumptive diagnosis of chlamydiosis was also made, based on a positive direct fluorescent monoclonal antibody reaction to chlamydial antigens in impression smears of liver and spleen. Chlamydial isolation attempts were unsuccessful. The toucan had been in contact with two macaws that had died 5 days before the toucan died and were diagnosed by histology as having herpesvirus hepatitis. PMID:2173540

    Fragments of the cloned hepatitis B virus (HBV) genome were assayed in vivo for the presence of a transcriptional enhancer element. We demonstrate that sequences positioned approximately 450 bp upstream from the HBcAg gene promoter are required for its efficient activity. These HBV stimulatory sequences activate transcription when inserted upstream to a heterologous SV40 early promoter. Like other known enhancer elements, this HBV sequence acts in an orientation-independent manner. Furthermor...

  16. Early serological diagnosis of viral hepatitis A using radiosaturation analysis

    The possibility was verified of utilizing the determination of specific IgM class antibodies to hepatitis A virus using the method of radiosaturation analysis, for early ethiological diagnosis of hepatitis A. The determination was made using the HAVAB-M kit by Abbott. A high and verifiable presence was found of these antibodies in the first to third weeks of the duration of the disease, positivity was observed up to day 125 from the onset of the diseases. Reliability of the determination of specific IgM antibodies to hepatitis A virus is high. Specific IgM antibodies to hepatitis A, determined using the radiosaturation analysis are a sensitive and specific indicator of the disease. The determination will mainly be used to advantage for identifying patients suffering from the anicteric form of the disease without any clinical manifestations, will substantially improve the ethiological diagnosis of acute hepatitis.

    2013-01-01

    Full Text Available Background/Aim. Hepatitis C virus (HCV infection is an important sociomedical problem worldwide because the chronification of the disease is frequent and the occurance of liver cirrhosis and hepatocellular carcinoma can be expected. The aim of this study was to determine the way of infection, pathohistological changes of the liver, virus genotype presence and sustained virological response after pegylated interferon and ribavirin therapy in prison inmates. Methods. The study included 52 patients with chronic HCV infection classified in two groups managed during 2008-2010. The first group consisted of prisoners (n = 22 and the second one of “non-prisoners” (n = 30. The patients from both groups underwent diagnostic preparation (biochemical analyses, liver biopsy, hepatitis virus detection and genotypisation using polymerase chain reaction issue. The treatment lasted for 24 weeks for virus genotypes 2 and 3, and 48 weeks for genotypes 1 and 4. Results. All the patients were males, approximately the same age (35 ± 4.1 and 31 ± 7.6 years. Virus genotype 1 was significantly more frequent in the prisoners (p < 0.05, that demanded longer treatment (48 weeks. At the same time, statistically significant higher number of patients, “non-prisoners”, achieved a sustained virological response (p < 0.01. Conclusion. Intravenous drug abuse and tattoos, separately or together, are the most frequent way of infection in prisoners. Dominant presence of virus genotype 1 resulted in lower number of patients with sustained virological response, probably regardless prison environment and regime.

    The clinicopathological findings of cerebral edema were investigated in patients with acute hepatic failure autopsied at Okayama University Hospital between 1970 and 1980 retrospectively. Nine (64%) of 14 hepatic failure cases were found to have cerebral edema during a post-mortem examination of the brain. Clinical features of the patients with cerebral edema were not significantly different from those of the patients without cerebral edema. However, general convulsions were observed more fre...

    Abstract The authors present a case of recurrent acute liver failure because of occupational exposure to organic solvents. A 35-year-old man with a 3-week history of worsening jaundice and flu-like symptoms was admitted to our hospital. Viral hepatitis serology and autoimmune factors were negative. The authors considered liver transplantation, but the patient's liver function spontaneously recovered. Liver biopsy revealed massive infiltration of neutrophils, but the cause of the acute hepatitis was not identified. Four months after discharge, the patient's liver function worsened again. The authors considered the possibility of antinuclear antibody-negative autoimmune hepatitis and initiated steroid treatment, which was effective. Four months after discharge, the patient was admitted for repeated liver injury. The authors started him on steroid pulse therapy, but this time it was not effective. Just before the first admission, he had started his own construction company where he was highly exposed to organic solvents, and thus the authors considered organic solvent-induced hepatitis. Although urine test results for organic solvents were negative, a second liver biopsy revealed severe infiltration of neutrophils, compatible with toxic hepatitis. Again, his liver function spontaneously improved. Based on the pathology and detailed clinical course, including the patient's high exposure to organic solvents since just before the first admission, and the spontaneous recovery of his liver damage in the absence of the exposure, he was diagnosed with toxic hepatitis. The authors strongly advised him to avoid organic solvents. Since then, he has been in good health without recurrence. This is the first report of recurrent acute liver failure because of exposure to organic solvents, which was eventually diagnosed through a meticulous medical history and successfully recovered by avoiding the causative agents. In acute liver failure with an undetermined etiology, clinicians

    2001-01-01

    AIM To detect immunohistochemically the presence of oval cells in chronic viral hepatitis with antibody against c-kit.METHODS We detected oval cells in paraffin-embedded liver sections of 3 normal controls and 26 liver samples from patients with chronic viral hepatitis, using immunohistochemistry with antibodies against c-kit, π-class glutathione Stransferase ( Tr-GST ) and cytokeratins 19(CK19).RESULTS Oval cells were not observed in normal livers. In chronic viral hepatitis, hepatic oval cells were located predominantly in the periportal . region and fibrosis septa,characterized by an ovoid nucleus, small size,and scant cytoplasm. Antibody against stem cell factor receptor, c-kit, had higher sensitivity and specificity than π-GST and CK19. About 50% -70% of c-kit positive oval cells were stained positively for either π-GST or CK19.CONCLUSION Oval cells are frequently detected in human livers with chronic viral hepatitis, suggesting that oval cell proliferation is associated with the liver regeneration in this condition.

    Ninety-seven symptomatic and five asymptomatic infections with viral hepatitis, type A (102 cases) were identified in members, guests and employees of a private country club in an outbreak associated with consuming food and ice prepared or handled by an employee of the club's kitchen pantry. Twenty-three symptomatic persons were tested by differential radioimmunoassay for immunoglobulin M (IgM) (acute-phase) hepatitis A antibody (anti-HAV) and all 23 were documented to be infected with hepatitis A virus (HAV). Forty-one member/guest cases had only a single exposure at the county club. Their incubation periods ranged from 21 to 40 days, with a mean of 30 days. The exposure of these single-day patrons occurred over a 14-day period. The index case was not icteric and only moderately symptomatic and was diagnosed retrospectively to have viral hepatitis, type A by serologic determination of IgM anti-HAV in blood samples. Four items implicated in disease transmission were potato salad, hot dogs, molded salmon and ice handled by the index case. Serologic screening of controls did not appear to alter the conclusions of the food item analysis. PMID:6249120

    Palta, Renee; McClune, Amy; Esrason, Karl

    2013-01-01

    Acute on chronic liver failure (ACLF) is rarely the initial manifestation of a malignant process or precipitated by the initiation of anti-viral treatment with a nucleoside or nucleotide agent. We report an unusual case of ACLF temporally associated with initiation of Entecavir for treatment of chronic hepatitis B. Early Hodgkin’s lymphoma (HL) was unmasked with initiation of the anti-viral treatment which may have exacerbated ACLF. To the best of our knowledge, this has not been described in...

  7. Detection of hepatitis A viral antigen by radioimmunoassay

    With coded samples, the effectiveness and specificity of a micro-SPIRA procedure for rapidly and quantitatively detecting type A hepatitis-associated antigen in large numbers of specimens from infected liver, stool, or serum has been demonstrated. Samples which were judged to be negative by IEM were found to contain significant levels of HAV antigen by this immunoradiometric technique. The detection of significant levels of HAV antigen in infected chimpanzees supports epidemiologic evidence of viremia during the acute stage of the disease. The results of this study suggest that the diagnosis of type A hepatitis by a convention serologic procedure may now be at hand. (auth)

    2013-01-01

    A middle-aged man had deteriorated rapidly in hospital after being misdiagnosed with acute alcoholic hepatitis. Acute Legionnaires disease (Legionellosis) was subsequently diagnosed on rapid antigen urinary testing and further confirmed serologically. This led to appropriate antibiotic treatment and complete clinical resolution. Physicians caring for patients with alcohol-related liver disease should consider Legionella pneumophila in their differential diagnosis even with a paucity of respir...

    De Cock, K M; Govindarajan, S; Redeker, A G

    1985-01-01

    Infection with the delta agent can only occur in the context of coexistent hepatitis B virus infection. We describe a patient in whom the clinical features of acute delta hepatitis developed when seroconversion from hepatitis B surface antigen to antibody had already occurred and diagnosis of recent acute hepatitis B was based on high titre IgM antibody to hepatitis B core antigen. We discuss the significance of such a serological profile, not previously described.

    Schizophrenia patients frequently develop somatic co-morbidity, including chronic viral hepatitis. The study of the quality of life in schizophrenia patients with concomitant viral hepatitis in the context of hospital pharmacotherapy, therefore, becomes an important task. We examined 60 schizophrenia patients with chronic viral hepatitis. Diagnosis was based on clinical, psychopathological, psychometric, clinical and laboratory methods, followed by statistical data processing. The features re...

  12. Core as a Novel Viral Target for Hepatitis C Drugs

    Guillaume Mousseau

    2010-08-01

    Full Text Available Hepatitis C virus (HCV infects over 130 million people worldwide and is a major cause of liver disease. No vaccine is available. Novel specific drugs for HCV are urgently required, since the standard-of-care treatment of pegylated interferon combined with ribavirin is poorly tolerated and cures less than half of the treated patients. Promising, effective direct-acting drugs currently in the clinic have been described for three of the ten potential HCV target proteins: NS3/NS4A protease, NS5B polymerase and NS5A, a regulatory phosphoprotein. We here present core, the viral capsid protein, as another attractive, non-enzymatic target, against which a new class of anti-HCV drugs can be raised. Core plays a major role in the virion’s formation, and interacts with several cellular proteins, some of which are involved in host defense mechanisms against the virus. This most conserved of all HCV proteins requires oligomerization to function as the organizer of viral particle assembly. Using core dimerization as the basis of transfer-of-energy screening assays, peptides and small molecules were identified which not only inhibit core-core interaction, but also block viral production in cell culture. Initial chemical optimization resulted in compounds active in single digit micromolar concentrations. Core inhibitors could be used in combination with other HCV drugs in order to provide novel treatments of Hepatitis C.

    We report a fatal case of acute gastroenteritis in a child with autism spectrum disorder. Multiple viral coinfections were detected by PCR in the patient's stool and digestive biopsy specimens. As viral detection is not necessarily associated with symptomatic disease, a semi-quantitative approach using cycle treshold values was proposed for the clinical interpretation of PCR. We discuss whether concomitant viral infections could be a risk factor for severe outcome in gastroenteritis cases. Individual risk factors are also addressed. PMID:26655270

    @@ The prognosis of patients with severe viral hepatitis is concerned by clinicians, patients and their relatives. Many factors may influence on the prognosis of patients with this disease. Many studies on the prognosis of severe viral hepatitis by multiple logistic regression analysis have shown generally consistent results.1-4 Previouly we established a scoring model of severe viral hepatitis (SMSVH) by logistic regression analysis.1 The aim of this study was to estimate prospectively the 6-month survival rate of patients with severe viral hepatitis using SMSVH.

  15. Cerebral edema associated with acute hepatic failure.

    Fujiwara,Masachika

    1985-02-01

    Full Text Available The clinicopathological findings of cerebral edema were investigated in patients with acute hepatic failure autopsied at Okayama University Hospital between 1970 and 1980 retrospectively. Nine (64% of 14 hepatic failure cases were found to have cerebral edema during a post-mortem examination of the brain. Clinical features of the patients with cerebral edema were not significantly different from those of the patients without cerebral edema. However, general convulsions were observed more frequently in patients later found to have cerebral edema. Moreover, the length of time from deep coma to death was much shorter in the brain edema cases with cerebral herniation than without herniation.

  16. Acute Alcoholic Hepatitis, the Clinical Aspects.

    Dugum, Mohannad F; McCullough, Arthur J

    2016-08-01

    Alcoholic hepatitis is an acute form of alcoholic liver disease with variable severity that develops in patients who usually have a history of prolonged and recent alcohol abuse. The diagnosis is clinical and depends on history, physical examination, and laboratory derangements. Liver biopsy is diagnostic but not universally performed, and noninvasive diagnostic modalities are under development. Scoring systems are used to assess severity of disease, predict mortality, and guide decisions for initiation of specific therapies. The natural history and long-term outcomes of alcoholic hepatitis, including recurrence, progression to cirrhosis, and mortality, vary and depend partly on abstinence from alcohol use. PMID:27373612

    We report a multilaboratory evaluation of hepatitis C virus (HCV) viral load assays to determine their linear range, reproducibility, subtype detection, and agreement. A panel of HCV RNA samples ranging in nominal concentration from 1.0 to 7.0 log10 IU/ml was constructed by diluting a clinical specimen (genotype 1b). Replicates of the panel were tested in multiple laboratories using the Abbott TaqMan analyte-specific reagent (Abbott reverse transcription-PCR [RT-PCR]), Roche TaqMan RUO (Roche...

  18. Assessment of specific IgM antibodies to core antigen of hepatitis B virus in acute and chronic hepatitis B using immunoradiometric assay

    A group of 24 patients with acute viral hepatitis B was assessed for specific antibodies against the ''core'' antigen class IgM (HBcAB IgM) during 1st-4th week of the illness. These specific antibodies were positive in all patients, the mean titre being 10-5. The high content of these antibodies persisted for 1-2 months after the onset of the disease. The assessment of specific antibodies against ''core'' antigen class IgM was also made in a group of 39 patients with chronic hepatitis. In these patients positive HBcAb IgM with a lower content were found (titre 10-3) than in the group with acute viral hepatitis B. Based on the results the conclusion is made that specific antibodies HBcAb class IgM are, in addition to the estimation of the surface antigen of the hepatitis B virus (HBsAg), one more indicator of acute viral hepatitis B. The assessment is diagnostically valuable, in particular in acute hepatitis of obscure etiology, in acute jaundice of obscure etiology for the period of low and short-term antigenemia.

  19. Analysis of hepatitis C viral dynamics using Latin hypercube sampling

    Pachpute, Gaurav; Chakrabarty, Siddhartha P.

    2012-12-01

    We consider a mathematical model comprising four coupled ordinary differential equations (ODEs) to study hepatitis C viral dynamics. The model includes the efficacies of a combination therapy of interferon and ribavirin. There are two main objectives of this paper. The first one is to approximate the percentage of cases in which there is a viral clearance in absence of treatment as well as percentage of response to treatment for various efficacy levels. The other is to better understand and identify the parameters that play a key role in the decline of viral load and can be estimated in a clinical setting. A condition for the stability of the uninfected and the infected steady states is presented. A large number of sample points for the model parameters (which are physiologically feasible) are generated using Latin hypercube sampling. An analysis of the simulated values identifies that, approximately 29.85% cases result in clearance of the virus during the early phase of the infection. Results from the χ2 and the Spearman's tests done on the samples, indicate a distinctly different distribution for certain parameters for the cases exhibiting viral clearance under the combination therapy.

  20. Changing trend of viral hepatitis -- 'A twenty one year report from Pakistan medical research council research centre, Jinnah Postgraduate Medical Centre, Karachi'

    To determine the frequency and pattern of Hepatitis B and C over the past twenty one years, in a liver research unit of Karachi. Retrospective analysis of the records of PMRC, Research Centre, Jinnah Postgraduate Medical Centre, Karachi, from 1987 to 2007 were reviewed. A special flow sheet was made where information of all patients with viral liver disease was entered. Patients having complete information of viral markers were included in the analysis. Cases with HBsAg, Anti HBc IgM positive and raised ALT were considered as acute Hepatitis B. HBs Ag/ Anti HBc IgG positive were considered as chronic Hepatitis B. Delta antibody positive with or without HBsAg were considered as Delta Hepatitis. Anti HCV positive and raised ALT more than ten times for less than 6 months were considered as acute Hepatitis C, whereas Anti HCV and HCV-RNA positive with or without raised ALT for more than six months were considered as chronic Hepatitis C. Anti HEV IgM and Anti HAV IgM positive were considered as acute Hepatitis E and A respectively. A total of 5193 cases fulfilling all criteria of viral hepatitis were seen in the past 21 years. Of the total 3247 (62.5 %) were males and 1946 (37.5 %) females giving a male to female ratio of 1.7:1 Hepatitis C was the most common infection seen in 2896 cases (55.8 %), followed by Hepatitis B in 1691 cases (32.6 %). Seventy five percent cases of Hepatitis B were males and 25 % females while 55% Hepatitis C cases were males and 45 % females. Hepatitis B was seen a decade earlier in different age groups than hepatitis C. Overall, out of the total 5193 cases, 2294 (44.2%) were of chronic hepatitis, 1430 (27.5%) cirrhosis, 1083 (20.8%) carriers and 346 (6.7%) had acute hepatitis (hepatitis B; 214 (61.8%), hepatitis C; 21 (6.0%). While hepatitis B and hepatitis C both were present in 3 (1.3%). Hepatitis E was 70 (20.2%) hepatitis A 12 (3.5%) and all markers were negative in 26 (7.5%) cases). Forty cases (0.8%) were of Hepatocellular carcinoma

    2006-01-01

    AIM: To describe the prevalence of transfusiontransmitted virus (TTV) infection in association with hepatitis A-E viral infections in different forms of liver diseases in North India.METHODS: Sera from a total number of:137 patients,including 37 patients with acute viral hepatitis (AVH), 37patients with chronic viral hepatitis (CVH), 31 patients with cirrhosis of liver and 32 patients with fulminant hepatic failure (FHF), were analyzed both for TTV-DNA and hepatitis A-E viral markers. Presence of hepatitis B virus (HBV), hepatitis C virus (HCV) and hepatitis E virus (HEV) infections was detected in different proportions in different groups. Moreover, TTV-DNA was simultaneously tested in 100 healthy blood donors also.RESULTS: None of the patients had hepatitis A virus (HAV) and hepatitis D virus (HDV) infections. Overall prevalence of TTV-DNA was detected in 27.1% cases with AVH, 18.9% cases with CVH, 48.4% cases with cirrhosis and 9.4% cases with FHF. TTV-DNA simultaneously tested in 100 healthy blood donors showed 27% positivity. On establishing a relation between TTV infection with other hepatitis viral infections, TTV demonstrated co-infection with HBV, HCV and HEV in these disease groups. Correlation of TTV with ALT level in sera did not demonstrate high ALT level in TTV-infected patients, suggesting that TTV does not cause severe liver damage.CONCLUSION: TTV infection is prevalent both in patients and healthy individuals in India. However, it does not have any significant correlation with other hepatitis viral infections, nor does it produce an evidence of severe liver damage in patients with liver diseases.

    The aim of this study was to evaluate the effectiveness of an educational method of providing viral hepatitis education for methadone maintenance patients. Four hundred forty participants were randomly assigned to either a control or a motivationally-enhanced viral hepatitis education and counseling intervention. Viral hepatitis A (HAV), B (HBV), and C (HCV) knowledge tests were administered at baseline, following each of two education sessions (post-education), and at a 3-month follow-up assessment. Results indicated a significant increase in knowledge of HAV, HBV, and HCV over time. No differences were found in knowledge between the intervention groups in knowledge acquisition regarding any of the hepatitis viruses suggesting that a motivational interviewing style may not augment hepatitis knowledge beyond standard counseling. A two-session viral hepatitis education intervention effectively promotes hepatitis knowledge and can be integrated in methadone treatment settings. PMID:24462241

    Full Text Available Background and Aim: The basic aim of this study was to find out the association of genotypes with host age, gender and viral load. Material and Methods: The present study was conducted at Social Security Hospital, Pakistan. This study included 320 patients with chronic hepatitis C virus (HCV infection who were referred to the hospital between November 2011 and July 2012. HCV viral detection and genotyping was performed and the association was seen between genotypes and host age, gender and viral load. Results : The analysis revealed the presence of genotypes 1 and 3 with further subtypes 1a, 1b, 3a, 3b and mixed genotypes 1b + 3a, 1b + 3b and 3a + 3b. Viral load quantification was carried out in all 151 HCV ribonucleic acid (RNA positive patients. The genotype 3a was observed in 124 (82.12% patients, 3b was found in 21 (13.91%, 1a was seen in 2 (1.32%, 1b in 1 (0.66%, mixed infection with 1b + 3a in 1 (0.66%, 1b + 3b in 1 (0.66% and 3a + 3b was also found in 1 (0.66% patient. Viral load quantification was carried out in all 151 HCV RNA positive patients and was compared between the various genotypes. The mean viral load in patients infected with genotype 1a was 2.75 × 10 6 , 1b 3.9 × 10 6 , 3a 2.65 × 10 6 , 3b 2.51 × 10 6 , 1b + 3a 3.4 × 106, 1b + 3b 2.7 × 106 and 3a + 3b 3.5 × 10 6 . An association between different types of genotypes and viral load was observed. Conclusion : Further studies should be carried out to determine the association of viral load with different genotypes so that sufficient data is available and can be used to determine the type and duration of therapy needed and predict disease outcome.

    The Centers for Disease Control and Prevention recommends integrating viral hepatitis prevention services with services for adults evaluated for sexually transmitted diseases (STDs). The Denver Public Health STD clinic began hepatitis B vaccination in 1999, hepatitis C virus (HCV) antibody (anti-HCV) testing in 2000, and hepatitis A vaccination in 2002. Rapid human immunodeficiency virus (HIV) testing began in late 2004. Hepatitis B vaccinations peaked in 2003 (31/100 client visits) when a fu...

  6. The ultrasonographic changes of gallbladder wall and the corresponding hepatic pathology in patients with chronic viral hepatitis

    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.

  7. [Two cases of acute hepatitis associated with Q fever].

    Yeşilyurt, Murat; Kılıç, Selçuk; Gürsoy, Bensu; Celebi, Bekir; Yerer, Mehmet

    2012-07-01

    Q fever which is caused by Coxiella burnetii, is a worldwide zoonosis. Many species of wild and domestic mammals, birds, and arthropods, are reservoirs of C.burnetii in nature, however farm animals are the most frequent sources of human infection. The most frequent way of transmission is by inhalation of contaminated aerosols. The clinical presentation of Q fever is polymorphic and nonspecific. Q fever may present as acute or chronic disease. In acute cases, the most common clinical syndromes are selflimited febrile illness, granulomatous hepatitis, and pneumonia, but it can also be asymptomatic. Fever with hepatitis associated with Q fever has rarely been described in the literature. Herein we report two cases of C.burnetii hepatitis presented with jaundice. In May 2011, two male cases, who inhabited in Malkara village of Tekirdag province (located at Trace region of Turkey), were admitted to the hospital with the complaints of persistent high grade fever, chills and sweats, icterus, disseminated myalgia and headache. Physical examination revealed fever, icterus and the patient appeared to be mildly ill but had no localizing signs of infection. Radiological findings of the patients were in normal limits. Laboratory findings revealed leukocytosis, increased hepatic and cholestatic enzyme levels, and moderate hyperbilirubinemia- mainly direct bilirubin, whereas serum C-reactive protein and erythrocyte sedimentation rate were found normal. Blood and urine cultures of the patients yielded no bacterial growth. Serological markers for acute viral hepatitis, citomegalovirus and Epstein-Barr virus infections, brucellosis, salmonellosis, toxoplasmosis and leptospirosis were found negative. Acute Q fever diagnosis of the cases were based on the positive results obtained by C.burnetii Phase II IgM and IgG ELISA (Vircell SL, Spain) test, and the serological diagnosis were confirmed by Phase I and II immunofluorescence (Vircell SL, Spain) method. Both cases were treated with

    AIM: To select valuable ultrasonographic predictors for the evaluation of hepatic inflammation and fibrosis degree in chronic hepatitis, and to study the value of ultrasonography in the evaluation of liver fibrosis and compensated liver cirrhosis in comparison with serology and histology.METHODS: Forty-four ultrasonographic variables were analyzed and screened using color Doppler ultrasound system in 225 patients with chronic viral hepatitis and compensated liver cirrhosis. The valuable ultrasonographic predictors were selected on the basis of a comparison with histopathological findings. The value of ultrasonography and serology in the evaluation of liver fibrosis degree and the diagnosis of compensated liver cirrhosis was also studied and compared. Meanwhile, the influencing factors on ultrasonographic diagnosis of compensated liver cirrhosis were also analyzed.RESULTS: By statistical analysis, the maximum velocity of portal vein and the degree of gall-bladder wall smoothness were selected as the valuable predictors for the inflammation grade (G), while liver surface, hepatic parenchymal echo pattern, and the wall thickness of gall-bladder were selected as the valuable predictors for the fibrosis stage (S). Three S-related independent ultrasonographyic predictors and three routine serum fibrosis markers (HA, HPCIII and CIV) were used to discriminate variables for the comparison of ultrasonography with serology. The diagnostic accuracy of ultrasonography in moderate fibrosis was higher than that of serology (P<0.01), while there were no significant differences in the general diagnostic accuracy of fibrosis as well as between mild and severe fibrosis (P<0.05). There were no significant differences between ultrasonography and serology in the diagnosis of compensated liver cirrhosis.However, the diagnostic accuracy of ultrasonography was higher in inactive liver cirrhosis and lower in active cirrhosis than that of serology (both P<0.05). False positive and false

    Biochemical and electron microscopic data indicate that the human hepatitis δ viral agent contains a covalently closed circular and single-stranded RNA genome that has certain similarities with viroid-like agents from plants. The sequence of the viral genome (1,678 nucleotides) has been determined and an open reading frame within the complementary strand has been shown to encode an antigen that binds specifically to antisera from patients with chronic hepatitis δ viral infections.

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

    MargareteOdenthal; HeidemarieHolzmann; NadineWinkel

    2013-01-01

    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...

    Background Hepatitis E virus is a major cause of outbreaks as well as sporadic hepatitis cases worldwide. The epidemiology of this enterically transmitted infection differs between developing and developed countries. The aims of this study were to describe HEV infection in Colombian patients and to characterize the genotype. Methods A prospective study was carried out on 40 patients aged over 15 with a clinical diagnosis of viral hepatitis, recruited from five primary health units in the city of Medellin, Colombia. Fecal samples obtained from the 40 consecutives cases were analyzed for HEV RNA using nested reverse transcription PCR for both ORF1 and ORF2-3. The amplicons were sequenced for phylogenetic analyses. Results Nine (22.5%) cases of HEV infection were identified in the study population. Three HEV strains obtained from patients were classified as genotype 3. No significant association was found between cases of Hepatitis E and the variables water drinking source, garbage collection system and contact with pigs. Conclusions This is the first prospective study of hepatitis E in Colombian patients. The circulation of the genotype 3 in this population is predictable considering the reports of the region and the identification of this genotype from pigs in the state of Antioquia, of which Medellin is the capital. Further studies are necessary to establish whether zoonotic transmission of HEV is important in Colombia. PMID:26886728

    The reason why abnormal immune response exists in acute rheumatic fever is not exactly explained. The influence of co-pathogens like certain viruses were mentioned regarding the initiation of the immunological reaction in acute rheumatic fever patients by several authors since 1970. This study was designed to find the role or effect of some viral infections in the development of rheumatic fever. In this study, 47 cases with acute rheumatic fever (acute rheumatic arthritis, acute rheumatic carditis, and chorea), 20 cases with chronic rheumatic fever, 20 cases with streptococcal pharyngitis, and 20 healthy age- and gender-matched control cases were involved. Serological and molecular tests were made including hepatitis B virus, hepatitis C virus, rubella virus, herpes simplex virus (HSV group 1), and Epstein-Barr virus (EBV). HBsAg, rubella IgM and EBV IgM positivity were not seen in any of patients with rheumatic fever. Although antiHBs seropositivity was higher in the control group, it was not statistically significant (p > 0.05). There was no difference in rubella IgG, HSV IgM seropositivity, either (p > 0.05). EBV DNA was searched by the polymerase chain reaction technique; due to the latent nature of the virus, no significant difference was found between the control group and the other groups (p > 0.05). In this study, no positive correlation could be found to support the synergism theories regarding the streptoccocus infection and viral infections in the development of acute rheumatic fever. Only EBV DNA positivity was found in all acute rheumatic fever cases but not in the control group may lead to further studies with larger series of patients. PMID:20401762

  1. Tracking virus-specific CD4+ T cells during and after acute hepatitis C virus infection.

    Michaela Lucas

    Full Text Available BACKGROUND: CD4+ T cell help is critical in maintaining antiviral immune responses and such help has been shown to be sustained in acute resolving hepatitis C. In contrast, in evolving chronic hepatitis C CD4+ T cell helper responses appear to be absent or short-lived, using functional assays. METHODOLOGY/PRINCIPAL FINDINGS: Here we used a novel HLA-DR1 tetramer containing a highly targeted CD4+ T cell epitope from the hepatitis C virus non-structural protein 4 to track number and phenotype of hepatitis C virus specific CD4+ T cells in a cohort of seven HLA-DR1 positive patients with acute hepatitis C in comparison to patients with chronic or resolved hepatitis C. We observed peptide-specific T cells in all seven patients with acute hepatitis C regardless of outcome at frequencies up to 0.65% of CD4+ T cells. Among patients who transiently controlled virus replication we observed loss of function, and/or physical deletion of tetramer+ CD4+ T cells before viral recrudescence. In some patients with chronic hepatitis C very low numbers of tetramer+ cells were detectable in peripheral blood, compared to robust responses detected in spontaneous resolvers. Importantly we did not observe escape mutations in this key CD4+ T cell epitope in patients with evolving chronic hepatitis C. CONCLUSIONS/SIGNIFICANCE: During acute hepatitis C a CD4+ T cell response against this epitope is readily induced in most, if not all, HLA-DR1+ patients. This antiviral T cell population becomes functionally impaired or is deleted early in the course of disease in those where viremia persists.

  4. Clinical significance of determination of changes of serum IL-2, sIL-2R, IL-13 and PDGF levels in patients with viral hepatitis B

    Objective: To study the clinical significance of changes of serum IL-2, sIL-2R, IL-13 and platalet derived growth factor (PDGF) levels in patients with viral hepatitis B. Methods: Serum IL-2, sIL-2R (with RIA) and IL-13, PDGF (with ELISA) levels were determined in 1) 20 patients with acute hepatitis B 2) 90 patients with chronic hepatitis 3) 40 patients with advanced hepatitis and 4) 45 controls. Results: Serum levels of IL-2 were slightly lower in patients with acute hepatitis than those in controls but without significant differences (P>0.05). The levels were significantly lower in patients with chronic and advarced hepatitis than those in controls (P<0.05). Serum levels of sIL-2R were significantly higher in all the hepatitis patients (P<0.01) with the higher levels in the most advanced cases. Serum IL-13 and PDGF levels were also significantly higher in all the hepatitis patients than those in controls (P<0.05 and P<0.01), with higher levels in more advanced patients. Conclusion: Changes of serum levels of these cytokins were closely related to the disease process of viral hepatitis and might be of prognostic importance. (authors)

    Liver biopsy is the gold standard method for the grading and staging of chronic viral hepatitis, but optimal biopsy specimen size remains controversial. The aim of this study was to evaluate the quality of liver specimen (number of portal tracts) and to evaluate the impact of the number of portal tracts in the staging of chronic hepatitis. Material and Methods: 468 liver biopsies from consecutive patients with hepatitis C virus and hepatitis B virus infection from 2009 to 2010 were evaluate...

  6. Scoring system in cirrhotics due to viral hepatitis

    Objective: To determine the association of serum cholesterol levels with Child-Pugh class in patients with decompensated chronic liver disease due to viral hepatitis. Methodology: Consecutive patients attending outpatient department or admitted in medical unit III were eligible if they had a diagnosis of cirrhosis secondary to viral hepatitis. Patients were excluded if alcoholic, diabetic, hypertensive, or with non-alcoholic fatty liver disease, autoimmune, metabolic, cardiovascular, cerebrovascular or kidney diseases and recent use of lipid-regulating drugs. Serum lipid profile was determined after an overnight fast of 12 hours. On the basis of serum total cholesterol, patients were divided into four groups; Group I with serum total cholesterol = 100 mg/dl, Group II with level of 101-150 mg/dl, Group III with level of 151-200 mg/dl and Group IV with serum total cholesterol level of > 200 mg/dl. Hepatic dysfunction was categorized according to Child-Pugh scoring system. Chi-square and Spearman's correlation testing with p < 0.05 was accepted as significant. Results: One hundred and fourteen patients met the inclusion criteria with a mean age of 40.32 +- 13.59 years. Among these 32 were females (28.1%) while 82 were males (71.9%). According to Child-Pugh class; 34 patients (29.8%) presented with Child-Pugh class A, 34 (29.8%) in class B and 46 (40.4%) were in class C. Serum cholesterol (total) and triglycerides had significant association with Child-Pugh class (p = 0.0001 and p = 0.004 respectively) suggesting that as severity of liver dysfunction increases; serum cholesterol and triglycerides levels decrease. Results also revealed that males were significantly more hypocholesterolemic than females (p = 0.006). Conclusion: Hypocholesterolemia is a common finding in decompensated chronic liver disease and has got significant association with Child-Pugh class. It may increase the reliability of Child-Pugh classification in assessment of severity and prognosis in

    The purpose of this study was to report the CT findings of four patients with hepatic abscess secondary to perforated acute cholecystitis. We retrospectively reviewed the CT findings of four patients with surgically proven hepatic abscess secondary to perforated acute cholecystitis. CT findings were analysed with respect to the observation of the gallbladder, pericholecystic space, hepatic lesions, and peritoneal cavity. All patients underwent cholecystectomy, with drainage of the hepatic abscess. CT findings of hepatic abscess secondary to perforated acute cholecystitis were hypodense mass formation in the pericholecystic space(n=3), irreguarity and wall defect of Gallbladder(n=4), thickened Gallbladder wall(n=4), stone with debris(n=4), and local or diffuse infiltration of the pericholecystic area(n=3), omentum, and mesentery. CT was helpful in diagnosing the hepatic abscess secondary to perforated acute cholecystitis.

    2011-01-01

    AIM: To determine the seroprevalence of anti-hepatitis A virus (HAV) antibodies in patients with chronic liver disease (CLD) and to justify the need for hepatitis A vaccination. METHODS: Patients (n = 119) were enrolled between July and September 2009. The diagnosis of CLD was based on the presence of viral markers for more than 6 mo. The diagnosis of liver cirrhosis was based on clinical, biochemical and radiological profiles. Patient serum was tested for anti-HAV IgG. RESULTS: The overall anti-HAV seroprevalence was 88.2%. The aetiology of CLD was hepatitis B in 96 patients (80.7%) and hepatitis C in 23 patients (19.3%). Mean age was 44.4 ± 14 years. Patients were grouped according to age as follows: 24 (20.2%) patients in the 21-30 years age group, 22 (18.5%) in the 31-40 years age group, 31 (26.1%) in the 41-50 years age group, 23 (19.3%) in the 51-60 years age group and 19 (16.0%) patients aged greater than 60 years, with reported seroprevalences of 66.7%, 95.5%, 93.5%, 91.3% and 94.7%, respectively. There was a marked increase of seroprevalence in subjects older than 30 years (P = 0.001). CONCLUSION: Our study demonstrated that patients aged greater than 30 years of age were likely to have natural immunity to hepatitis A. Therefore, hepatitis A vaccination may not be routinely required in this age group.

    Patients with dengue virus (DENV) infection may also present acute viral encephalitis through an unknown mechanism. Here, we report that encephalitic DENV-infected mice exhibited progressive hunchback posture, limbic seizures, limbic weakness, paralysis, and lethality 7 days post-infection. These symptoms were accompanied by CNS inflammation, neurotoxicity, and blood-brain barrier destruction. Microglial cells surrounding the blood vessels and injured hippocampus regions were activated by DENV infection. Pharmacologically depleting microglia unexpectedly increased viral replication, neuropathy, and mortality in DENV-infected mice. In microglia-depleted mice, the DENV infection-mediated expression of antiviral cytokines and the infiltration of CD8-positive cytotoxic T lymphocytes (CTLs) was abolished. DENV infection prompted the antigen-presenting cell-like differentiation of microglia, which in turn stimulated CTL proliferation and activation. These results suggest that microglial cells play a key role in facilitating antiviral immune responses against DENV infection and acute viral encephalitis. PMID:27279150

  10. The study on serologic index of hepatic fibrosis in viral hepatitis

    Objective: To explore the applicable value of hyaluronic acid (HA), collagen type IV(C-IV), N-terminal procollagen III(P III NP), laminin (LN), NAG and the PGA ratio (PT/GCT/Apo- A1) in the detection of diagnosis of liver fibrosis. Methods: Serum markers were studied in 217 patients (contain 82 pathologies) with viral hepatitis:(1)HA,C-IV, P III NP, LN were determined by radio-immunoassay. (2)NAG and PGA ratio were determined by biochemical auto-analyzer. Results: (1)Serum HA, NAG and PGA ratio elevated significantly with the progress of inflammation and fibrosis(P2-S3 fibrotic grades. (3) Serum LN remained unchanged in different histological grades, therefore it was not able to reflect the progress of inflammation and liver fibrosis. Conclusions: (1)Co-detection of serum HA, NAG and PGA ratio provides accurate and reliable indexes for the clinical diagnosis. Dynamic observation of their changes may be used to know the progress of disease and be used as reliable indexes to judge the therapeutic effect of antifibrotic drugs. (2) To some extent it is important to differentiate middle hepatitis from mild hepatitis of serum P III NP and C-IV, therefore these serum markers may be taken as indexes to reflect levels of hepatitis severity.

    Abstract Clinical outcomes in kidney transplant recipients (KTRs) with hepatitis B virus (HBV) have not been thoroughly evaluated. Here, we investigated recent posttransplant clinical outcomes of KTRs with HBV and compared them with KTRs with hepatitis C virus (HCV) and seronegative KTRs. Of 3855 KTRs from April 1999 to December 2011, we enrolled 3482 KTRs who had viral hepatitis serology data; the patients were followed up for 89.1 ± 54.1 months. The numbers of recipients with HBV and HCV were 160 (4.6%) and 55 (1.6%), respectively. We analyzed the clinical outcomes, including overall mortality and graft failure, among patients who had undergone kidney transplantation. Patients with HBV showed poorer survival (P = 0.019; adjusted hazard ratio [HR] = 2.370; 95% confidence interval [CI]: 1.155–4.865) than KTRs without HBV. However, the graft survival of patients with chronic hepatitis B did not differ from that of patients without HBV. Hepatic complications were the primary causes of mortality of KTRs with HBV. Mortality significantly correlated with a higher grade of inflammation (P = 0.002) and with the use of lamivudine or adefovir antiviral treatment (P = 0.016). HBV-positive KTRs treated with the new-generation antiviral agent entecavir showed improved patient survival compared with KTRs receiving lamivudine (log-rank P = 0.050). HCV did not affect patient survival; however, it increased the incidence of graft failure (P = 0.010; adjusted HR = 2.899; 95% CI: 1.289–6.519). KTRs with HCV had an increased incidence of acute rejection (log-rank P = 0.005, crude HR = 2.144; 95% CI: 1.341–3.426; P = 0.001). KTRs with chronic hepatitis B may exhibit poor survival due to post-transplantation hepatic complications. Pretransplant histological liver evaluations and adequate antiviral management with potent nucleoside/nucleotide analogues are needed to improve the survival of KTRs with chronic hepatitis B even when liver

    2015-01-01

    Viral gastroenteritis is the most frequent cause of acute gastroenteritis (AGE) of childhood. The aim of this study was to determine the prevalence of viral agents including astrovirus, rotavirus, adenovirus, enterovirus, norovirus, parechovirus, Aichivirus and sapovirus in children with AGE in a pediatric Turkish population. Fecal specimens of 240 children with AGE were investigated by polymerase chain reaction, and viral agents were identified in 131 (54.6%) samples. The distribution of viral agents was as follows: 56 (42.8%) norovirus, 44 (33.6%) rotavirus, 29 (22.1%) enterovirus, 21 (16.0%) adenovirus, 21 (16.0%) parechovirus, 5 (3.8%) sapovirus and 1 (0.8%) Aichivirus. Single and multiple viral agents were detected in 38.8% and 15.8% of patients, respectively. The duration of hospitalization was longer in children with multiple viral agents than in those infected with a single viral agent (p<0.001). While the highest rate of rotavirus infection was detected in winter, the highest rate of norovirus was found in the summer. In conclusion, norovirus and rotavirus are the most frequent causes of childhood AGE in our country. PMID:26613223

  15. Differing results of direct and indirect solid phase radioimmunoassay for HBsAg in acute hepatitis

    In 54 patients suffering from active viral hepatitis the indirect solid phase radioimmunoassay (ind-SPRIA) for HBsAg was positive in 9 cases the direct solid phase radioimmunoassay (d-SPRIA) being negative. In 2 further cases ind-SPRIA was positive during several weeks but d-SPRIA only once. AntiHBc could be detected in 9 of these patients. In 7 patients the usual decrease of the transaminase activity was followed by a second elavation with prolongation of the disease. The unknown factor detected by ind-SPRIA suggests a special of acute hepatitis. (orig.)

Clinical features can be either acute or subacute onset that results in neurological deficits such as weakness and/or numbness of extremities as well as autonomic dysfunctions. While there are some etiologies related, a viral infection is common. However, the hepatitis A virus rarely causes myelitis. This report provides details of a hepatitis A infectious patient who developed myelitis as comorbidity. Although, the disability was initially severe, the patient successfully recovered with corticosteroid treatment.

  18. Detection of serum leptin levels in patients with viral hepatitis and fatty liver

    In order to find out the correlations between serum leptin levels and viral hepatitis, the serum leptin levels in 167 patients with viral chronic hepatitis, 87 patients with fatty liver, and 80 control subjects were determined by radioimmunoassay. The liver function (ALT, AST), glucose(Glu) and total cholesterol(TC) in these patients were also measured. Compared with controls and patients with fatty liver, the levels of serum leptin in patients with viral hepatitis were significantly increased (P0.05). The increase of serum leptin levels in the patients with viral hepatitis was correlated positively with the severity of liver inflammation. Therefore, the leptin can be regarded as an indicator to reflect the severity of liver inflammation. (authors)

  19. Gastric Emptying Time in Acute and Chronic Hepatitis B Patients

    Anorexia, nausea, and vomiting are one of the most frequent symptoms in viral hepatitis patients. These may be due to poorly detoxified substances by dysfunctioned hepatocytes or by gastritis, but the pathophysiology is not totally understood. The symptoms interfere with adequate nutrient intake and are managed by metaclopramide, which accelerates gastric emptying. Thus delayed gastric emptying may well be a contributing factor to such symptoms. To determine such a relationship, we measured gastric emptying time in 11 normal subjects, 9 acute (AVH), and 12 chronic B viral hepatitis (CVH) patients. All were males with a mean age of 23 years. An egg was labeled with 0.5 mCi of 99mTc-sulfur colloid, fried, then eaten between 2 slices of bread with 100 cc of water. Anterior and posterior images were taken at 20 minute intervals over a 2 hour period. A geometric mean of activity pertaining to the gastric region was measured, and T1/2 was calculated from the time activity curve. T1/2 for normal the group was 57.8 ± 6.3 minutes while that for the AVH and CVH group was 58.2 ± 8.2 (p=0.40) and 64.1 ± 10.5 (p=0.09), respectively. There was 1 AVH patient and 4 CVH patients with prolonged T1/2. Anorexia and nausea was seen in 71% and 46% of the patients, respectively. 80% and 60% of the patients with prolonged T1/2 had anorexia and nausea, respectively.

    2005-01-01

    Hepatitis C virus (HCV) infection causes chronic liver diseases and is a global public health problem. Detailed analyses of HCV have been hampered by the lack of viral culture systems. Subgenomic replicons of the JFH1 genotype 2a strain cloned from an individual with fulminant hepatitis replicate efficiently in cell culture. Here we show that the JFH1 genome replicates efficiently and supports secretion of viral particles after transfection into a human hepatoma cell line (Huh7). Particles ha...

    1989-07-01

    The authors studied the effect of a dry protein mixture on the clinical course and protein and pigmentary metabolism, functional tests of the liver in 223 patients with viral hepatitis. It was found that this mixture favours reduction of the icteric period, more rapid restoration of the liver function and improves prognosis. The dry protein mixture is recommended to be included in dietotherapy of patients with viral hepatitis. PMID:2800480

    2012-01-01

    Abnormal bone metabolism and dysfunction of the calcium-parathyroid hormone-vitamin D axis have been reported in patients with viral hepatitis.Some studies suggested a relationship between vitamin D and viral hepatitis.Genetic studies have provided an opportunity to identify the proteins that link vitamin D to the pathology of viral hepatitis (i.e.,the major histocompatibility complex class Ⅱ molecules,the vitamin D receptor,cytochrome P450,the renin-angiotensin system,apolipoprotein E,liver X receptor,toll-like receptor,and the proteins regulated by the Sp1 promoter gene).Vitamin D also exerts its effects on viral hepatitis via non-genomic factors,i.e.,matrix metalloproteinase,endothelial vascular growth factor,prostaglandins,cyclooxygenase-2,and oxidative stress.In conclusion,vitamin D could have a beneficial role in viral hepatitis.Calcitriol is best used for viral hepatitis because it is the active form of the vitamin D3 metabolite.

  5. Glucagon: acute actions on hepatic metabolism.

    Miller, Russell A; Birnbaum, Morris J

    2016-07-01

    Type 2 diabetes mellitus is the result of impaired systemic control of glucose homeostasis, in part through the dysregulation of the hormone glucagon. Glucagon acts on the liver to increase glucose production through alterations in hepatic metabolism, and reducing the elevated glucagon signalling in diabetic patients is an attractive strategy for the treatment of hyperglycaemia. Here we review the actions of the hormone in the liver, focusing on the acute alterations of metabolic pathways. This review summarises a presentation given at the 'Novel data on glucagon' symposium at the 2015 annual meeting of the EASD. It is accompanied by two other reviews on topics from this symposium (by Mona Abraham and Tony Lam, DOI: 10.1007/s00125-016-3950-3 , and by Young Lee and colleagues, DOI: 10.1007/s00125-016-3965-9 ) and an overview by the Session Chair, Isabel Valverde (DOI: 10.1007/s00125-016-3946-z ).

  6. Bloodborne Viral Hepatitis Infections among Drug Users: The Role of Vaccination

    Paolo Mezzelani

    2009-01-01

    Full Text Available Drug use is a prevalent world-wide phenomenon and hepatitis virus infections are traditionally a major health problem among drug users (DUs. HBV and HCV, and to a lesser extent HAV, are easily transmitted through exposure to infected blood and body fluids. Viral hepatitis is not inevitable for DUs. Licensed vaccines are available for hepatitis A and hepatitis B. The purpose of this overview is to show some epidemiological data about HBV and the other blood-borne viral hepatitis among DUs and to summarize and discuss use of hepatitis vaccinations in this population. Successful vaccination campaigns among DUs are feasible and well described. We try to focus on the most significant results achieved in successful vaccination programs as reported in scientific literature. Vaccination campaigns among DUs represent a highly effective form of health education and they are cost-saving.

    @@ There are six types of viral hepatitis, namely, A, B, C, D, E and G. Two types are mainly classified according to the routes of transmission. Hepatitis types A and E are transmitted by gastrointestinal tract (stool-mouth transmission). The others (B, C, D and G)are transmitted by parenteral route, the most common of which is blood transmission.

    Liver transplantation for human immunodeficiency virus (HIV) positive patients with viral hepatitis co-infection is increasingly offered in many North American and European liver transplant centers. Prior studies have demonstrated acceptable post-transplant outcomes and no increased risk of HIV complications in patients co-infected with hepatitis B virus (HBV). However, liver transplantation in HIV positive patients with hepatitis C virus (HCV) has poorer outcomes overall, requiring careful s...

  9. Early-onset acute transverse myelitis following hepatitis B vaccination and respiratory infection: case report

    Fonseca Luiz Fernando

    2003-01-01

    Full Text Available Acute transverse myelitis is an acute inflammatory process of the spinal cord and it is a rare clinical syndrome in childhood. In this paper, we report a case of 3 years-old boy who developed acute onset tetraparesia following a viral respiratory infecction and hepatitis B vaccination. Magnetic resonance imaging of the spinal cord disclosed signal-intensity abnormalities from C4 to C3. A diagnosis of acute transverse myelitis was made and the patient was treated with IV methylprednisolone and IV immunoglobulin. The child had a fair outcome despite of the very acute course of the disease and the presence of a cervical sensory level which usually harbor a poor prognosis.

    Mansuy, Jean Michel; Peron, Jean Marie; Bureau, Christophe; Alric, Laurent; Vinel, Jean Pierre; Izopet, Jacques

    2004-01-01

    Hepatitis E is an acute and self-limiting hepatitis, and the causative agent, hepatitis E virus, is excreted in feces and orally transmitted. The disease is common in Asia and Africa, causing outbreaks or sporadic cases. In Europe, the infection is generally observed after a history of travel in an area of endemicity. We report on an autochthonous case in southwestern France in which the diagnosis was based on molecular tools rather than serological testing.

  11. Hepatitis C Viral Infection in Children: Updated Review

    2016-01-01

    Hepatitis C virus (HCV) infection is a major medical challenge affecting around 200 million people worldwide. The main site of HCV replication is the hepatocytes of the liver. HCV is a positive enveloped RNA virus from the flaviviridae family. Six major HCV genotypes are implicated in the human infection. In developed countries the children are infected mainly through vertical transmission during deliveries, while in developing countries it is still due to horizontal transmission from adults. Minimal nonspecific and brief symptoms are initially found in approximately 15% of children. Acute and chronic HCV infection is diagnosed through the recognition of HCV RNA. The main objective for treatment of chronic HCV is to convert detected HCV viremia to below the detection limit. Children with chronic HCV infection are usually asymptomatic and rarely develop severe liver damage. Therefore, the benefits from current therapies, pegylated-Interferon plus ribavirin, must be weighed against their adverse effects. This combined treatment offers a 50-90% chance of clearing HCV infection according to several studies and on different HCV genotype. Recent direct acting antiviral (DAA) drugs which are well established for adults have not yet been approved for children and young adults below 18 years. The most important field for the prevention of HCV infection in children would be the prevention of perinatal and parenteral transmission. There are areas of focus for new lines of research in pediatric HCV-related disease that can be addressed in the near future.

  12. Endoplasmic Reticulum Stress Induced Synthesis of a Novel Viral Factor Mediates Efficient Replication of Genotype-1 Hepatitis E Virus.

    Hepatitis E virus (HEV) causes acute hepatitis in many parts of the world including Asia, Africa and Latin America. Though self-limiting in normal individuals, it results in ~30% mortality in infected pregnant women. It has also been reported to cause acute and chronic hepatitis in organ transplant patients. Of the seven viral genotypes, genotype-1 virus infects humans and is a major public health concern in South Asian countries. Sporadic cases of genotype-3 and 4 infection in human and animals such as pigs, deer, mongeese have been reported primarily from industrialized countries. Genotype-5, 6 and 7 viruses are known to infect animals such as wild boar and camel, respectively. Genotype-3 and 4 viruses have been successfully propagated in the laboratory in mammalian cell culture. However, genotype-1 virus replicates poorly in mammalian cell culture and no other efficient model exists to study its life cycle. Here, we report that endoplasmic reticulum (ER) stress promotes genotype-1 HEV replication by inducing cap-independent, internal initiation mediated translation of a novel viral protein (named ORF4). Importantly, ORF4 expression and stimulatory effect of ER stress inducers on viral replication is specific to genotype-1. ORF4 protein sequence is mostly conserved among genotype-1 HEV isolates and ORF4 specific antibodies were detected in genotype-1 HEV patient serum. ORF4 interacted with multiple viral and host proteins and assembled a protein complex consisting of viral helicase, RNA dependent RNA polymerase (RdRp), X, host eEF1α1 (eukaryotic elongation factor 1 isoform-1) and tubulinβ. In association with eEF1α1, ORF4 stimulated viral RdRp activity. Furthermore, human hepatoma cells that stably express ORF4 or engineered proteasome resistant ORF4 mutant genome permitted enhanced viral replication. These findings reveal a positive role of ER stress in promoting genotype-1 HEV replication and pave the way towards development of an efficient model of the

  16. CT and MRI diagnosis of acute hepatic injury

    To evaluate and compare MR and CT in diagnosis of acute traumatic hepatic laceration, ten patients with acute hepatic rupture underwent CT scan and/or MRI in the first 24 hours after injury. The injury was graded as mild (50% of one lobe). In the first 24 hours after injury, 33.3% (3/9) and 28.6%(2/7) of the hepatic injury demonstrated isodensity and isointensity on plain CT scan and T1-weighted images. All the lesions (100%) were clearly identified as marked hyperintensity on T2-weighted images. On T2WI, T1WI and non-contrast CT, 100%, 57.1% and 55.6% of the acute hepatic injuries could be graded respectively. Delayed complications occurred in four patients with deep hepatic injury about 1 to 3 weeks after injury. T2-weighted MR imaging is more sensitive and useful for detection of the type and severity of acute hepatic rupture. Follow-up MRI or CT within the first few weeks after injury is needed in patients with deep hepatic injury for detection of delayed complications

    2000-01-01

    The significance of the pronounced durable systemic arterial hypotension (SAH) in the origin of an acute postoperative ischemic hepatitis (APIH) was established, basing on the analysis of 40 clinical observations. Its occurrence is promoted by hemorrhage with 30% and more the circulating blood volume (CBV) deficiency, chronic cardiovascular system and pulmonary diseases, liver cirrhosis, shock, massive infusions of the blood and its components, the abdominal aorta atherosclerosis with stenosis of tr. coeliacus, a. hepatica. Forgoing SAH, the presence of promoting factors, jaundice, the transpherase activity raising in 3-5 times, the level of blood coagulating factors reduction, stable intestinal paresis were diagnostically significant symptoms. Experimental model of an APIH was elaborated in dogs, which occurs due to hypotension, caused by CBV reduction by 40% during two hours. The refractoriness of a. hepatica propria to the blood reinfusion was established. In the APIH occurrence threat the perftoran application in the 20 ml/kg dosage is the prophylaxis method as well as the method of the curative tactics choice. PMID:10857279

    Hepatitis B and C are big health issues worldwide as more than 400 million people arc suffering from chronic hepatitis B and C which result in more than 1.4 million deaths each year.According to a study done by Pakistan Medical Research Council in 2007-08,7.6%Pakistani population suffered with hepatitis B and C.with around 4.8%with hepatitis C only.Government of Pakistan has taken different initiatives like vaccination,patient safety,blood screening,education and awareness about disease but still there is high prevalence of hepatitis in Pakistan.According to some studies injecting drug users have the highest prevalence of hepatilis B and C in the country.The follow-up studies and documentation of hepatitis patients was not very good which need to be improved.There is no recent large scale study on risk factors and prevalence of hepatitis B and C in Pakistan so it should be done on an urgent basis.If government set up regional laboratories for prevalence study and also a central institute for hepatitis research and treatment,the disease could be prevented in better and proper way.The treatment of hepatitis is very costly and a developing country like Pakistan cannot afford such high costs.Therefore more focus should be on preventive measures.

    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.

    2016-06-01

    The Regional Public Health Authority was notified about four cases of viral hepatitis (B and C) among patients with pre-event history of hospitalization at an oncological ward. An outbreak investigation was commenced in response. Forty-seven cases of viral hepatitis B and C in 39 patients hospitalized during the period from September 2009 to July 2010 were registered. We found an association between parenteral treatment and disease (hepatitis B: χ(2) = 49.53; P < 0.001; hepatitis C: χ(2) = 22.42; P < 0.001). Despite using disposable materials, there remains a risk of transmission of bloodborne virus infections in hospitals due to poor adherence to standard procedures. PMID:26944899

    We investigated the variance of liver biopsy frequency and histological findings among patients with chronic viral hepatitis attending 10 medical centres in Denmark. Patients who tested positive for HBsAg or HCV- RNA were retrieved from a national clinical database (DANHEP) and demographic data......, cirrhosis had developed in 23% after 20 y of infection. Age above 40 y was a better predictor of cirrhosis than elevated ALT. National database comparison may identify factors of importance for improved management of patients with chronic viral hepatitis. Udgivelsesdato: 2007-null......, laboratory analyses and liver biopsy results were collected. A total of 1586 patients were identified of whom 69.7% had hepatitis C, 28.9% hepatitis B, and 1.5% were coinfected. In total, 771 (48.6%) had a biopsy performed (range 33.3-78.7%). According to the Metavir classification, 29.3% had septal fibrosis...

  9. Detection of serum leptin levels in patients with viral hepatitis C

    To evaluate changes of serum leptin levels in patients with viral hepatitis C(HCV), serum leptin levels were determined by RIA in 65 patients with viral chronic hepatitis C and in 80 control subjects ,liver function (ALT, AST) , glucose (Glu) , and total cholesterol (TC) were evaluated too. Campared with controls, the levels of serum leptin were significantly increased in patients with HCV (P0.05). The levels of serum leptin increased in patients with HCV, which correlates positively with the severity of liver inflammation, so that leptin can be regarded as an index which reflects the severity of liver inflammation.

    As the fifth most common cancer in men and the eighth most common cancer in women, hepatocellular carcinoma (HCC) is the leading cause of cancer-related deaths worldwide, with standard chemotherapy and radiation being minimally effective in prolonging survival. Virus hepatitis, particularly HBV and HCV infection is the most prominent risk factor for HCC development. Mammalian target of rapamycin (mTOR) pathway is activated in viral hepatitis and HCC. mTOR inhibitors have been tested successfu...

  11. Linker phosphorylation of Smad3 promotes fibro-carcinogenesis in chronic viral hepatitis of hepatocellular carcinoma

    Murata, Miki; Yoshida, Katsunori; Yamaguchi, Takashi; Matsuzaki, Koichi

    2014-01-01

    Epidemiological and clinical data point to a close association between chronic hepatitis B virus infection or chronic hepatitis C virus infection and development of hepatocellular carcinoma (HCC). HCC develops over several decades and is associated with fibrosis. This sequence suggests that persistent viral infection and chronic inflammation can synergistically induce liver fibrosis and hepatocarcinogenesis. The transforming growth factor-β (TGF-β) signaling pathway plays a pivotal role in di...

  13. Hepatitis B Virus Core Protein Stimulates the Proteasome-Mediated Degradation of Viral X Protein

    Kim, Jung-Hwan; Kang, Seongman; Kim, Joon; Ahn, Byung-Yoon

    2003-01-01

    Hepatitis B virus (HBV) X protein (HBx) plays an essential role in viral replication and in the development of hepatocellular carcinoma. HBx has the ability to transactivate the expression of all HBV proteins, including the viral core protein HBc. Consistent with its regulatory role, HBx is relatively unstable and is present at low levels in the cell. We report here that the level of HBx was significantly reduced by the coexpression of HBc in cultured human hepatoma cells, whereas the level o...

    2012-01-01

    Full Text Available Background: Most outbreaks of viral hepatitis in India are caused by hepatitis E. Recently in the year 2009, Modasa town of Sabarkantha district in Gujarat witnessed the outbreak of hepatitis B. Purpose: An attempt was made to study the outbreak clinically and serologically, to estimate the seropositivity of hepatitis B Virus among the cases and their contacts and to know the seroprevalence of hepatitis B envelope antigen (HBeAg and IgM antibody against hepatitis B core antigen (IgM HBcAb out of all the Hepatitis B surface Antigen (HBsAg positive ones. Materials and Methods: Eight hundred and fifty-six (856 cases and 1145 contacts were evaluated for hepatitis B markers namely HBsAg, HBeAg and IgM HBcAb by enzyme-linked immuno Sorbent Assay (ELISA test. Results: This outbreak of viral hepatitis B in Modasa, Gujarat was most likely due to unsafe injection practices. Evidence in support of this was collected by Government authorities. Most of the patients and approximately 40% of the surveyed population gave history of injections in last 1.5-6 months. Total 664/856 (77.57% cases and 20/1145 (1.75% contacts were found to be positive for HBsAg. 53.41% of the positive cases and 52.93% of the positive contacts were HBeAg-positive and thus in a highly infectious stage. Conclusions: Inadequately sterilized needles and syringes are an important cause of transmission of hepatitis B in India. Our data reflects the high positivity rate of a hepatitis B outbreak due to such unethical practices. There is a need to strengthen the routine surveillance system, and to organise a health education campaign targeting all health care workers including private practitioners, especially those working in rural areas, as well as the public at large, to take all possible measures to prevent this often fatal infection.

    Full Text Available OBJECTIVE: to estimate the prevalence of infection by respiratory viruses in pediatric patients with cancer and acute respiratory infection (ARI and/or fever. METHODS: cross-sectional study, from January 2011 to December 2012. The secretions of nasopharyngeal aspirates were analyzed in children younger than 21 years with acute respiratory infections. Patients were treated at the Grupo em Defesa da Criança Com Câncer (Grendacc and University Hospital (HU, Jundiaí, SP. The rapid test was used for detection of influenza virus (Kit Biotrin, Inc. Ireland, and real-time multiplex polymerase chain reaction (FTD, Respiratory pathogens, multiplex Fast Trade Kit, Malta for detection of influenza virus (H1N1, B, rhinovirus, parainfluenza virus, adenovirus, respiratory syncytial virus, human parechovirus, bocavirus, metapneumovirus, and human coronavirus. The prevalence of viral infection was estimated and association tests were used (χ2 or Fisher's exact test. RESULTS: 104 samples of nasopharyngeal aspirate and blood were analyzed. The median age was 12 ± 5.2 years, 51% males, 68% whites, 32% had repeated ARIs, 32% prior antibiotic use, 19.8% cough, and 8% contact with ARIs. A total of 94.3% were in good general status. Acute lymphocytic leukemia (42.3% was the most prevalent neoplasia. Respiratory viruses were detected in 50 samples: rhinoviruses (23.1%, respiratory syncytial virus AB (8.7%, and coronavirus (6.8%. Co-detection occurred in 19% of cases with 2 viruses and in 3% of those with 3 viruses, and was more frequent between rhinovirus and coronavirus 43. Fever in neutropenic patients was observed in 13%, of which four (30.7 were positive for viruses. There were no deaths. CONCLUSIONS: the prevalence of respiratory viruses was relevant in the infectious episode, with no increase in morbidity and mortality. Viral co-detection was frequent in patients with cancer and ARIs.

  1. Epidemiological characteristics and clinical manifestations of acute non-A-E hepatitis

    2010-01-01

    Full Text Available Background/Aim. Acute non-A, non-B, non-C, non-D, non-E hepatitis (non-A-E AH is an acute disease of the liver of unknown etiology for which one or more new, so far undetected, hepatotropic viruses may be responsible. The frequency of non-A-E AH ranges from 3.8% to 33.9%, and therefore it has a significant place within current infectology and hepatology. The aim of our study was to establish the frequency, clinical and biochemical characteristics, natural course and outcome of non-A-E AH and compare them with control groups affected by acute viral hepatitis A, B and C. Methods. This descriptive-analytic prospective study included 31 patients with non-A-E AH treated at the Institute of Infectious and Tropical Diseases, Clinical Center of Serbia, Belgrade, from 2003 to 2008. They were followed up during the period not less than 6 months. The controls involved randomly selected patients, treated at the same time with a definite diagnosis of acute viral hepatitis A, B and C. Statistical data analysis used Mann-Whitney Utest, Student's t-test and variance analysis. The value of p < 0.05 was considered statistically significant. Results. The frequency of non-A-E AH was 7.6%. Almost no difference was found between sexes (male/female ratio was 1 : 1.07; it was developed in all age groups, with the highest incidence in the middle age (mean age was 38.32 ± 15.3 years. It appeared equally throughout the whole year. Out of risk factors, inoculation risk was predominant (before all, dental interventions, mostly involving urban population living in comfortable conditions. The duration of incubation varied much ranging from 20 to 180 days (median 60 days. By clinical course, moderate and icteric forms were most common, mostly corresponding to acute hepatitis A and C. On the other hand, by duration of the disease (mean duration was 67.1 ± 27.1 and chronic transformation, non-A-E AH resembled to acute hepatitis B. Progression to chronicity was recorded in 9

    2000-07-01

    Hepatic infarction is relatively uncommon and is usually related to surgery or interventional procedures. Pancreatitis-associated hepatic infarction has not been reported in the literature, and we now describe a case of hepatic infarction in a 31-year-old man with acute pancreatitis. Initial CT scanning demonstrated an enlarged pancreas with multifocal fluid collection, and a large wedge-shaped low attenuation lesion was seen in the right lobe of the liver along with thrombi in the posteroinferior branch of the right portal vein. Hepatic arteriography and SMA portography revealed a pseudoaneurysm in the right hepatic artery, thrombi in the main portal vein and its posteroinferior branch, and perfusion defects confined to S6 of the liver.

    2003-08-01

    Full Text Available From 1992 to 1995 we studied 232 (69% male, 87% Caucasian anti-human immunodeficiency virus (anti-HIV positive Brazilian patients, through a questionnaire; HIV had been acquired sexually by 50%, from blood by 32%, sexually and/or from blood by 16.4% and by an unknown route by 1.7%. Intravenous drug use was reported by 29%; it was the most important risk factor for HIV transmission. The alanine aminotransferase quotient (qALT was >1 for 40% of the patients, 93.6% had anti-hepatitis A virus antibody, 5.3% presented hepatitis B surface antigen, 44% were anti-hepatitis B core antigen positive and 53.8% were anti-hepatitis C virus (anti-HCV positive. The anti-HCV test showed a significant association with qALT>1. Patients for whom the probable HIV transmission route was blood had a 10.8 times greater risk of being anti-HCV positive than patients infected by other routes. Among 30 patients submitted to liver biopsy, 18 presented chronic hepatitis.

  4. A new transmissible agent causing acute hepatitis, chronic hepatitis and cirrhosis in dogs.

    Jarrett, W F; O'Neil, B W

    1985-06-15

    There is a hepatitis of dogs which occurs in acute, persistent and chronic forms. Histological studies of spontaneous cases suggested that several apparently diverse hepatic diseases might be stages of one process. This was also implied by follow up studies and case histories: acute non-lethal episodes were followed later by the development of chronic hepatitis, cirrhosis and liver failure. Serum was taken and homogenates of liver were made from three field cases representing different putative temporal stages of the complex. These were injected into experimental dogs and a hepatitis was induced in all. The cytopathological and histological changes were the same in all animals and were identical to field cases. Acute lethal disease and persistent infections were produced. Two second passages were carried out and an identical condition was induced, characterised by recurrent episodes of subclinical hepatitis and persistent infection. It is suggested that the disease might be named canine acidophil cell hepatitis in view of the pathognomonic cytopathology. Specific morphological criteria have been established for this hepatitis.

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

    Uta eDrebber

    2013-12-01

    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.

  12. A homosexual japanese man with acute hepatitis due to hepatitis B virus genotype ae, concurrent with amebic colitis

    Sakaguchi,Kohsaku

    2007-02-01

    Full Text Available We report herein a case with acute hepatitis due to hepatitis B virus genotype Ae, concurrent with amebic colitis. A 39-year-old homosexual Japanese man was admitted to our hospital with jaundice. Laboratory tests showed an elevation of transaminase and positivity for hepatitis B surface antigen and IgM-type antibody to hepatitis B core antigen. The hepatitis B virus genotype was determined to be Ae. Furthermore, a mud-like stool with blood and mucous had sometimes been noted during the past 3 years, and amebic colitis was shown by colonofi berscopy during hospitalization. The patient was diagnosed with acute hepatitis B, concurrent with amebic colitis, and was successfully treated with lamivudine and metronidazole. In Japanese patients with acute hepatitis B virus genotype A infection, homosexual activity tends to be high. Furthermore, in Japanese homosexual men, amebiasis has been increasing. Thus, in Japanese patients with acute hepatitis B, a determination of genotype should be performed in order to investigate the route of transmission of hepatitis B virus, and a search for amebiasis should be performed in patients with acute hepatitis due to hepatitis B virus genotype A. Furthermore, education of homosexual men regarding hepatitis B virus, hepatitis B virus vaccination, and amebiasis is urgently required.

  13. Defective interfering viral particles in acute dengue infections.

    Dongsheng Li

    Full Text Available While much of the genetic variation in RNA viruses arises because of the error-prone nature of their RNA-dependent RNA polymerases, much larger changes may occur as a result of recombination. An extreme example of genetic change is found in defective interfering (DI viral particles, where large sections of the genome of a parental virus have been deleted and the residual sub-genome fragment is replicated by complementation by co-infecting functional viruses. While most reports of DI particles have referred to studies in vitro, there is some evidence for the presence of DI particles in chronic viral infections in vivo. In this study, short fragments of dengue virus (DENV RNA containing only key regulatory elements at the 3' and 5' ends of the genome were recovered from the sera of patients infected with any of the four DENV serotypes. Identical RNA fragments were detected in the supernatant from cultures of Aedes mosquito cells that were infected by the addition of sera from dengue patients, suggesting that the sub-genomic RNA might be transmitted between human and mosquito hosts in defective interfering (DI viral particles. In vitro transcribed sub-genomic RNA corresponding to that detected in vivo could be packaged in virus like particles in the presence of wild type virus and transmitted for at least three passages in cell culture. DENV preparations enriched for these putative DI particles reduced the yield of wild type dengue virus following co-infections of C6-36 cells. This is the first report of DI particles in an acute arboviral infection in nature. The internal genomic deletions described here are the most extensive defects observed in DENV and may be part of a much broader disease attenuating process that is mediated by defective viruses.

    Virological tools, including serological and molecular tools, are needed to diagnose chronic hepatitis B and C infections. They may also be useful to establish their prognosis, but they have found their principal application in guiding treatment decisions and assessing the virological responses to therapy. The goal of chronic hepatitis B therapy is to prevent progression of liver disease. This is achieved if HBV replication is durably abolished or significantly reduced. In HBeAg-positive pati...

  15. Acute hemorrhagic leukoencephalomyelitis in a man with viral myocarditis.

    Kitulwatte, Indira D; Kim, Patrick J H; Pollanen, Michael S

    2015-09-01

    We report a case of acute hemorrhagic leukoencephalomyelitis in a man with viral myocarditis. A 48-year-old previously healthy male was found dead in his locked apartment. At autopsy he was found to be malnourished, and his lungs showed gross evidence of bilateral pneumonia with abscess formation and bullous emphysema. Multiple petechial hemorrhages were observed in the brain and mainly involved white matter in the cerebral hemispheres including the corpus callosum and internal capsule, as well as the cerebellum, brainstem, and spinal cord. Microscopy of the brain and spinal cord revealed perivenular hemorrhages, central microthrombi in venules with fibrin exudation into the subcortical white matter, and early perivenular demyelination associated with scanty mixed cellular infiltrates. Other microscopic features included widespread diffuse viral myocarditis, extensive suppurative bronchopneumonia, and chronic bronchitis. This case illustrates the death of a man with a rare fatal disease associated with two other potentially lethal diseases. The case also illustrates the importance of a holistic approach when determining the cause of death, especially when there are competing causes of death. PMID:26148811

  17. Micro-RNA-122 Levels in Acute Liver Failure and Chronic Hepatitis C

    Dubin, Perry H.; Yuan, Hejun; Devine, Robert K.; Hynan, Linda S.; Jain, Mamta K.; Lee, William M.

    2016-01-01

    MicroRNA-122 (miR-122) is the foremost liver-related micro-RNA, but its role in the hepatocyte is not fully understood. To evaluate whether circulating levels of miR-122 are elevated in chronic-HCV for a reason other than hepatic injury, we compared serum level in patients with chronic hepatitis C to other forms of liver injury including patients with acute liver failure and healthy controls. MiR-122 was quantitated using sera from 35 acute liver failure patients (20 acetaminophen-induced, 15 other etiologies), 39 chronic-HCV patients and 12 controls. In parallel, human genomic DNA (hgDNA) levels were measured to reflect quantitatively the extent of hepatic necrosis. Additionally, six HIV–HCV co-infected patients, who achieved viral clearance after undergoing therapy with interferon and ribavirin, had serial sera miR-122 and hgDNA levels measured before and throughout treatment. Serum miR-122 levels were elevated approximately 100-fold in both acute liver failure and chronic-HCV sera as compared to controls (P<0.001), whereas hgDNA levels were only elevated in acute liver failure patients as compared to both chronic-HCV and controls (P<0.001). Subgroup analysis showed that chronic-HCV sera with normal aminotransferase levels showed elevated miR-122 despite low levels of hepatocyte necrosis. All successfully treated HCV patients showed a significant Log10 decrease in miR-122 levels ranging from 0.16 to 1.46, after sustained viral response. Chronic-HCV patients have very elevated serum miR-122 levels in the range of most patients with severe hepatic injury leading to acute liver failure. Eradication of HCV was associated with decreased miR-122 but not hgDNA. An additional mechanism besides hepatic injury may be active in chronic-HCV to explain the exaggerated circulating levels of miR-122 observed. PMID:24895202

    2015-11-01

    Full Text Available BACKGROUND: Liver enzyme elevations are common in human immunodeficiency virus (HIV-infected patients, and their diagnosis and management becomes a challenge because of complex pathogenic mechanisms. Liver enzyme abnormalities may be worsened by hepatitis B (HBV or hepatitis C (HCV infection, which each have their own risks for chronic immune-mediated liver disease along with direct cytotoxicity. OBJECTIVES: The present study was done to identify various liver function abnormalities in HIV and viral hepatitis co- infection METHODS: The study included 22 HIV seropositive patients along with serology positive for hepatitis (19 patients were HBsAg positive and 3 patients were HCV positive who presented to Sri Ramachandra Medical College and Hospital from the year 2012 to 2014. Complete haemogram, blood urea, serum creatinine, liver function tests, CD4 count, and ultrasound abdomen was done for all the patients. LFT abnormalities were compared with HIV positive patients without hepatitis (78 patients. RESULTS: LFT abnormalities were significant in comparison to patients with negative hepatitis serology. Only a modest elevation of liver enzymes was seen in hepatitis. Co-infection. Majority of the patients had elevation of transaminases and INR was normal in all HCV positive patients. CONCLUSION: HBV and HCV coinfection increases the incidence of LFT abnormality. Only a modest elevation of liver enzymes was seen in hepatitis co-infection.

    Monitoring the progression of hepatitis C virus (HCV) includes clinical, biochemical, and histological parameters. Quantitation of viral load by reverse-transcription polymerase chain reaction (RT-PCR) may offer a more reliable marker of disease status. Conflicting reports on viral titers may reflect heterogeneity of patient population, mode of infection, and viral type/subtype. The aim of this study was to correlate quantitative serum viral load with alanine transaminase (ALT) and histological status in a homogenous population. The study population consisted of 77 Rhesus-negative women with chronic hepatitis C type 1b. Homogenous features of this study population included: same defined source of infection (contaminated anti-D immunoglobulin); same duration of disease (17 years at the time of study); same viral type/subtype; same ethnic origin; all healthy child-bearing females at the time of infection; and an absence of competing risk factors for infectious and other liver diseases. None of the patients had received antiviral treatment at the time of study. Liver biopsy was performed on all patients. All biopsies were scored by a single histopathologist who was blinded to the clinical and viral status of each patient. A weak, but statistically significant, correlation (rs =.26; P <.05) between serum viral load and the degree of inflammation (mean value: 3.87 +/- 2.17 [SD]) was found. There was no significant correlation between serum viral load and the degree of fibrosis (mean value: 0.84 +/- 0.8 [SD]; P =.06). There was no significant correlation between serum viral load and ALT, although there was a correlation between ALT and the degree of inflammation (rs =.241; P =.035). PMID:10051496

    Full Text Available Abstract Background The occurrence of tuberculosis (TB, human immunodeficiency virus (HIV, and viral hepatitis infections in the same patient poses unique clinical and public health challenges, because medications to treat TB and HIV are hepatotoxic. We conducted an observational study to evaluate risk factors for HBsAg and/or anti-HCV reactivity and to assess differences in adverse events and TB treatment outcomes among HIV-infected TB patients. Methods Patients were evaluated at the beginning, during, and at the end of TB treatment. Blood samples were tested for aspartate aminotransferase (AST, alanine aminotransferase (ALT, total bilirubin (BR, complete blood count, and CD4+ T lymphocyte cell count. TB treatment outcomes were assessed at the end of TB treatment according to international guidelines. Results Of 769 enrolled patients, 752 (98% had serologic testing performed for viral hepatitis: 70 (9% were reactive for HBsAg, 237 (31% for anti-HCV, and 472 (63% non-reactive for both markers. At the beginning of TB treatment, 18 (26% patients with HBsAg reactivity had elevated liver function tests compared with 69 (15% patients non-reactive to any viral marker (p = 0.02. At the end of TB treatment, 493 (64% were successfully treated. Factors independently associated with HBsAg reactivity included being a man who had sex with men (adjusted odds ratio [AOR], 2.1; 95% confidence interval [CI], 1.1–4.3 and having low TB knowledge (AOR, 1.8; CI, 1.0–3.0. Factors most strongly associated with anti-HCV reactivity were having injection drug use history (AOR, 12.8; CI, 7.0–23.2 and living in Bangkok (AOR, 15.8; CI, 9.4–26.5. The rate of clinical hepatitis and death during TB treatment was similar in patients HBsAg reactive, anti-HCV reactive, both HBsAg and anti-HCV reactive, and non-reactive to any viral marker. Conclusion Among HIV-infected TB patients living in Thailand, markers of viral hepatitis infection, particularly hepatitis C virus

    TREM1 (Triggering Receptor Expressed on Myeloid Cells 1) is a pro-inflammatory receptor expressed by phagocytes, which can also be released as a soluble molecule (sTREM1). The roles of TREM1 and sTREM1 in liver infection and inflammation are not clear. Here we show that patients with hepatitis B virus (HBV) or hepatitis C virus (HCV) infection manifest elevated serum levels of sTREM1. In mice, experimental viral hepatitis induced by infection with Lymphocytic Choriomeningitis Virus (LCMV)-WE was likewise associated with increased sTREM1 in serum and urine, and with increased TREM1 and its associated adapter molecule DAP12 in the liver. Trem1-/- mice showed accelerated clearance of LCMV-WE and manifested attenuated liver inflammation and injury. TREM1 expression in the liver of wild-type mice was mostly confined to infiltrating neutrophils, which responded to LCMV by secretion of CCL2 and TNF-α, and release of sTREM1. Accordingly, the production of CCL2 and TNF-α was decreased in the livers of LCMV-infected Trem1-/- mice, as compared to LCMV-infected wildtype mice. These findings indicate that TREM1 plays a role in viral hepatitis, in which it seems to aggravate the immunopathology associated with viral clearance, mainly by increasing the inflammatory activity of neutrophils.

  6. New animal models for hepatitis C viral infection and pathogenesis studies

    Dina Kremsdorf; Nicolas Brezillon

    2007-01-01

    Hepatitis C virus (HCV) is a major cause of chronic liver disease, cirrhosis and hepatocellular carcinoma (HCC).In man, the pathobiological changes associated with HCV infection have been attributed to both the immune system and direct viral cytopathic effects. Until now, the lack of simple culture systems to infect and propagate the virus has hampered progress in understanding the viral life cycle and pathogenesis of HCV infection,including the molecular mechanisms implicated in HCV-induced HCC. This clearly demonstrates the need to develop small animal models for the study of HCV-associated pathogenesis. This review describes and discusses the development of new HCV animal models to study viral infection and investigate the direct effects of viral protein expression on liver disease.

  7. Morbidity and mortality assessment in acute hepatitis-e

    Hepatitis-E is an enterically transmitted virus causing acute hepatitis. Mostly it is a self-limiting clinical course, but can be life threatening in certain high risk groups. Pakistan is endemic for Hepatitis-E with limited published literature. The aim of this study is to evaluate the predictors of mortality in patients with acute Hepatitis-E. Methods: We analyzed the medical records of 369 adult patients with Hepatitis-E infection admitted at Aga khan University Hospital, from January 1996 to December 2010. Details of their laboratory investigations, clinical course and complications such as FHF and mortality were noted. The outcome was compared, and determinants of mortality were evaluated in important patient subgroups. Results: Out of 369 patients with Hepatitis-E, 326 (88.3%) were discharged after full recovery. Out of these 22 (6%) patients had chronic liver disease CLD in this study, of whom 10 (2.7%) expired (p-value <0.001). There were about 67 (18%) pregnant patients, with a mean gestational age of 29.19 ± 7.68 weeks and 5 (1.4%) pregnant patients died (p-value=0.23). A total of 58 (15.7%) patients were co-infected with other hepatotropic virus, and a comparison did not find an increased risk of mortality in this group. Conclusion: This study showed that Hepatitis-E is significantly associated with mortality in patients suffering from pre-existing chronic liver disease. Pregnancy was not a determinant of mortality in Hepatitis-E patients in this study, and neither was co-infection with other Hepatotropic viruses. (author)

  8. 131I-Bromsulphalein in the evaluation of hepatic function during reconvalescence after viral hepatitis

    The combined use of biochemical and radionuclide tests (the clearance of 13+1I-bromsulphalein) made it possible to reveal significant differences in 53 patients in the time of complete reparation of hepatic function and the period of reconvalescence after hepatitis A and B. The period of reconvalescence in patients with hepatitis B was more prolonged. Dynamic observation and appropriate treatment is recommended for these patients

  9. Carboxy terminal peptide of type I procollagen and epidermal growth factor in patients with different viral hepatitis

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

    Guillaume Mousseau; Snyder, John K.; Arthur Donny Strosberg; Virginia Takahashi; Smitha Kota

    2010-01-01

    Hepatitis C virus (HCV) infects over 130 million people worldwide and is a major cause of liver disease. No vaccine is available. Novel specific drugs for HCV are urgently required, since the standard-of-care treatment of pegylated interferon combined with ribavirin is poorly tolerated and cures less than half of the treated patients. Promising, effective direct-acting drugs currently in the clinic have been described for three of the ten potential HCV target proteins: NS3/NS4A protease, NS5B...

  12. Viral arthritis.

    Marks, Michael; Marks, Jonathan L

    2016-04-01

    Acute-onset arthritis is a common clinical problem facing both the general clinician and the rheumatologist. A viral aetiology is though to be responsible for approximately 1% of all cases of acute arthritis with a wide range of causal agents recognised. The epidemiology of acute viral arthritis continues to evolve, with some aetiologies, such as rubella, becoming less common due to vaccination, while some vector-borne viruses have become more widespread. A travel history therefore forms an important part of the assessment of patients presenting with an acute arthritis. Worldwide, parvovirus B19, hepatitis B and C, HIV and the alphaviruses are among the most important causes of virally mediated arthritis. Targeted serological testing may be of value in establishing a diagnosis, and clinicians must also be aware that low-titre autoantibodies, such as rheumatoid factor and antinuclear antibody, can occur in the context of acute viral arthritis. A careful consideration of epidemiological, clinical and serological features is therefore required to guide clinicians in making diagnostic and treatment decisions. While most virally mediated arthritides are self-limiting some warrant the initiation of specific antiviral therapy. PMID:27037381

The features of the host's immune response (host resistance reflect the coevolution between hosts and pathogens that has occurred over millennia, and that has also resulted in a number of strategies developed by viruses to improve fitness and survival within the host (viral adaptation. In this review, we discuss viral adaptation to host immune pressure via protein–protein interactions and sequence-specific mutations. Specifically, we will present the “state of play” on viral escape mutations to host T-cell responses in the context of the hepatitis C virus, and their influence on infection outcome.Keywords: hepatitis C virus, viral adaptation, immune escape, adaptive immune response

  14. Cholestatic hepatitis due to Salmonella typhi

    2011-04-01

    Full Text Available Salmonella infection occurs worldwide and is still an important public health problem in many developing countries. The infection can affect almost all major organs including the liver. Severe hepatic involvement with a clinical feature of acute hepatitis is a rare complication. In this paper, a 39-year-old male with acute cholestatic typhoid hepatitis is presented. The case had a tender hepatomegaly and elevated serum alanine and aspartate transaminase, alkaline phosphatase, and gamma glutamyl transferase levels; these features cannot been distinguished from those of acute viral hepatitis. Serological and viral markers of acute viral hepatitis were negative. No pathology could be determined in abdomen Ultrasonography (USG or Magnetic Reso - nance (MR Cholangiography. As enteric fever is a common infection, the recognition of salmonella hepatitis is of clinical importance. When patients from an endemic or outbreak area present acute febrile hepatitis, typhoid fever should be a consideration.

    Hepatitis C virus (HCV) is a positive single-stranded RNA virus of enormous global health importance, with direct-acting antiviral therapies replacing an immunostimulatory interferon-based regimen. The dynamics of HCV positive and negative-strand viral RNAs (vRNAs) under antiviral perturbations have not been studied at the single-cell level, leaving a gap in our understanding of antiviral kinetics and host-virus interactions. Here, we demonstrate quantitative imaging of HCV genomes in multiple infection models, and multiplexing of positive and negative strand vRNAs and host antiviral RNAs. We capture the varying kinetics with which antiviral drugs with different mechanisms of action clear HCV infection, finding the NS5A inhibitor daclatasvir to induce a rapid decline in negative-strand viral RNAs. We also find that the induction of host antiviral genes upon interferon treatment is positively correlated with viral load in single cells. This study adds smFISH to the toolbox available for analyzing the treatment of RNA virus infections. PMID:27128351

  16. Acute Hepatic Failure in a Dog after Xylitol Ingestion.

    Schmid, Renee D; Hovda, Lynn R

    2016-06-01

    Xylitol is a five-carbon sugar alcohol produced from natural resources frequently used as a sugar substitute for humans. We report the development and successful treatment of acute hepatic failure and coagulopathy in a dog after xylitol ingestion. A 9-year-old 4.95 kg (10.9 lb) neutered male Chihuahua was evaluated at a veterinary clinic for vomiting after ingesting 224 g (45 g/kg, 20.5 g/lb) of granulated xylitol. Hypoglycemia developed within 1-2 h, elevated liver values, suggesting the development of acute hepatic failure, within 12 h and coagulopathy less than 24 h after ingestion. Treatment included maropitant, intravenous dextrose, phytonadione, metronidazole, and fresh frozen plasma. N-acetylcysteine (NAC) and S-adensoyl-L-methionine (SAMe) provided hepatic detoxification and support. The dog survived and liver values returned to normal within 1 month post ingestion. No adverse effects to hepatic function have been identified 2 years after acute xylitol toxicity. This paper is one of the few reports of successful management of a dog with hypoglycemia, hepatic failure, and coagulopathy caused by xylitol toxicity. To date, this is the highest published xylitol dose survived by a dog, as well as the only reported case that documents laboratory changes throughout the course of toxicity and includes normal hepatic indices for 7 months following xylitol toxicity. The rapidly expanding use of xylitol in a variety of products intended for human consumption has led to a rise in xylitol toxicity cases reported in dogs, and clinicians should be aware that more dogs may potentially be exposed and develop similar manifestations.

    Although there is not one specific sign or symptom related to alcoholic hepatitis (AH), a constellation of symptoms and signs can help make the diagnosis of AH with reasonable accuracy. Documentation of chronic and active alcohol abuse is paramount in making a diagnosis of AH. Clinical presentation after abstinence for more than 3 m should raise doubts about the diagnosis of AH and dictate the need for considering other causes of liver disease, decompensation of alcoholic cirrhosis, sepsis an...

  18. [Consequences of extrahepatic manifestations of hepatitis C viral infection (HCV)].

    Pawełczyk, Agnieszka

    2016-01-01

    The hepatitis C virus (HCV) is a primarily hepatotropic virus. However, numerous extrahepatic symptoms are observed in patients chronically infected with HCV, e.g. cryoglobulinemia, lymphoproliferative disorders, kidney diseases, disturbances of the central and peripheral nervous system, thyroid gland, pancreas, lymph nodes and pituitary gland, that develop at various times after the infection. Complex mechanisms underlie these processes, both molecular, related to direct effects of the virus on cells or tissues and indirect mechanisms, resulting from the response of the immune system to infection (via cytokines or oxidative stress), and from the antiviral treatment used. Understanding these mechanisms may contribute to the definition of new prognostic factors, important for the early diagnosis of the infection, which in turn may improve treatment efficacy. This paper is a review of the incidence of selected extrahepatic manifestations of HCV infection and their underlying pathogenetic mechanisms and risk factors. PMID:27117111

  20. Acute exacerbation of autoimmune hepatitis induced by Twinrix

    Antal Csepregi; Gerhard Treiber; Christoph R(o)cken; Peter Malfertheiner

    2005-01-01

    We report on a 26-year-old man who presented with severe jaundice and elevated serum liver enzyme activities after having received a dose of Twinrix(○R). In his past medical history, jaundice or abnormal liver function tests were never recorded. Following admission, an elevated immunoglobulin G level and antinuclear antibodies at a titer of 320 with a homogenous pattern were found. Histology of a liver biopsy showed marked bridging liver fibrosis and a chronic inflammation, compatible with autoimmune hepatitis. Treatment was started with budesonide and ursodeoxycholic acid,and led to complete normalization of the pathological liver function tests. We believe that Twinrix(○R) led to an acute exacerbation of an unrecognized autoimmune hepatitis in our patient. The pathogenesis remains to be clarified. It is tempting to speculate that inactivated hepatitis A virus and/or recombinant surface antigen of the hepatitis B virus -as seen in patients with chronic hepatitis C and unrecognized autoimmune hepatitis who were treated with interferon alpha-might have been responsible for disease exacerbation.

  3. Positive serology for viral hepatitis and donor self-exclusion in Southern Brazil

    Julia De Luca Maccarini

    2013-07-01

    Full Text Available Introduction Despite the great advances in serological testing for transfusion-transmitted infections, the selection of blood donors by blood bank operators remains the only way to avoid transmission within the testing window period. Part of this selection is the self-exclusion form, on which the donors can exclude their blood from donation without any explanation. This study assessed the clinical and epidemiological characteristics related to positivity for viral hepatitis and to the use of the confidential self-exclusion (CSE form. Methods This transversal study analyzed the data collected from blood donors' files in a hospital in Southern Brazil. Univariate and multivariate analyses identified the clinical and epidemiological variables related to positive serologies of viral hepatitis and to whether the donor was self-excluded. Results Of the 3,180 donors included in this study, 0.1% tested positive for HBsAg, 2.1% for anti-HBc, and 0.9% for anti-HCV. When the 93 donors with positive serologies for viral hepatitis were compared with those who were negative, a greater proportion of the positive serology group was found to have had a history of blood transfusions (OR=4.908; 95%CI=1.628 - 14.799; p<0.01, had repeatedly donated (OR=2.147; 95%CI=1.236 - 3.729; p<0.01, and used the CSE form for self-exclusion (OR=7.139; 95%CI=2.045 - 24.923; p<0.01. No variables were independently associated with self-exclusion. Conclusions A history of blood transfusion, repeated donations, and self-exclusion are factors that should be considered during viral hepatitis screenings in blood banks.

    Full Text Available Abstract Background Identification of risk factors of acute hepatitis C virus (HCV infection in Egypt is crucial to develop appropriate prevention strategies. Methods We conducted a case–control study, June 2007-September 2008, to investigate risk factors for acute HCV infection in Egypt among 86 patients and 287 age and gender matched controls identified in two infectious disease hospitals in Cairo and Alexandria. Case-patients were defined as: any patient with symptoms of acute hepatitis; lab tested positive for HCV antibodies and negative for HBsAg, HBc IgM, HAV IgM; and 7-fold increase in the upper limit of transaminase levels. Controls were selected from patients’ visitors with negative viral hepatitis markers. Subjects were interviewed about previous exposures within six months, including community-acquired and health-care associated practices. Results Case-patients were more likely than controls to have received injection with a reused syringe (OR=23.1, CI 4.7-153, to have been in prison (OR=21.5, CI 2.5-479.6, to have received IV fluids in a hospital (OR=13.8, CI 5.3-37.2, to have been an IV drug user (OR=12.1, CI 4.6-33.1, to have had minimal surgical procedures (OR=9.7, CI 4.2-22.4, to have received IV fluid as an outpatient (OR=8, CI 4–16.2, or to have been admitted to hospital (OR=7.9, CI 4.2-15 within the last 6 months. Multivariate analysis indicated that unsafe health facility practices are the main risk factors associated with transmission of HCV infection in Egypt. Conclusion In Egypt, focusing acute HCV prevention measures on health-care settings would have a beneficial impact.

    Full Text Available The aim of the study was to determine the aetiologic agent causing deaths in two flocks of Pekin ducklings at the age of 12 d in Poland. on the basis of clinical symptoms and pathological changes, viral hepatitis infection was suspected in the birds. During the necropsy, liver sections were collected, from which total cellular RNA was isolated. Then, real-time polymerase chain reaction (RT-PCR was performed using primers complementary to the pre-S region of the duck hepatitis virus genome. In all liver samples, the presence of a 530 bp PCR product was detected. The RT-PCR demonstrated the presence of genetic material of duck hepatitis virus type 1 (DH type 1 in the examined ducklings.

  11. Hepatocellular carcinoma, human immunodeficiency virus and viral hepatitis in the HAART era

    Douglas C Macdonald; Mark Nelson; Mark Bower; Thomas Powles

    2008-01-01

    The incidence of hepatocellular carcinoma (HCC) in patients with human immunodeficiency virus (HIV) is rising. HCC in HIV almost invariably occurs in the context of hepatitis C virus (HCV) or hepatitis B virus (HBV) co-infection and, on account of shared modes of transmission, this occurs in more than 33% and 10% of patients with HIV worldwide respectively. It has yet to be clearly established whether HIV directly accelerates HCC pathogenesis or whether the rising incidence is an epiphenomenon of the highly active antiretroviral therapy (HAART) era, wherein the increased longevity of patients with HIV allows long-term complications of viral hepatitis and cirrhosis to develop. Answering this question will have implications for HCC surveillance and the timing of HCV/HBV therapy, which in HIV co-infection presents unique challenges. Once HCC develops, there is growing evidence that HIV co-infection should not preclude conventional therapeutic strategies, including liver transplantation.

    1997-01-01

    Hepatitis B is a major public health problem even though safe and effective vaccines have been available for over 10 years. Because hepatitis B infection is largely asymptomatic with long term complications occurring after many years it has not received the attention it deserves. Strategies to immunise those at high risk have failed to control the disease. Delegates to the World Health Assembly of the World Health Organisation recommended in May 1992 that all countries should integrate hepati...

    2012-01-01

    Full Text Available OBJECTIVE: To evaluate viral vaccine antibody levels in children with acute lymphoblastic leukemia after chemotherapy and after vaccine booster doses. METHODS: Antibody levels against hepatitis B, rubella, measles and mumps vaccine antigens were evaluated in 33 children after completing chemotherapy (before and after vaccine booster doses and the results were compared to the data of 33 healthy children matched for gender, age and social class. RESULTS: After chemotherapy, 75.9%, 67.9%, 59.3% and 51.7% of the patients showed low antibody titers that would be unlikely to protect against exposure to measles, rubella, hepatitis B and mumps, respectively. After receiving a vaccine booster dose for these antigens the patients had high antibody levels consistent with potential protection against measles, mumps and hepatitis B, but not against rubella. CONCLUSION: Extra doses of measles-mumps-rubella plus hepatitis B vaccines are recommended in acute lymphoblastic leukemia patients submitted to treatment after hematologic recovery. After this, viral vaccine antibody levels should be verified to define the individual's protective status.

    Few studies have evaluated the impact of viral infections on the daily management of patients with systemic lupus erythematosus (SLE). We analyzed the etiology and clinical features of acute viral infections arising in patients with SLE and their influence on the diagnosis, prognosis, and treatment of SLE. Cases occurring within the last 5 years were selected from the databases of 3 large teaching hospitals. Acute viral infections were confirmed by the identification of specific antiviral IgM antibodies and subsequent seroconversion with detection of specific IgG antibodies. In autopsy studies, macroscopic findings suggestive of viral infection were confirmed by direct identification of the virus or viruses in tissue samples. We performed a MEDLINE search for additional cases reported between January 1985 and March 2008. We included 88 cases (23 from our clinics and 65 from the literature review) of acute viral infections in patients with SLE. Twenty-five patients were diagnosed with new-onset SLE (fulfillment of the 1997 SLE criteria) associated with infection by human parvovirus B19 (n = 15), cytomegalovirus (CMV; n = 6), Epstein-Barr virus (EBV; n = 3), and hepatitis A virus (n = 1). The remaining 63 cases of acute viral infections arose in patients already diagnosed with SLE: in 18 patients, symptoms related to infection mimicked a lupus flare, 36 patients, including 1 patient from the former group who presented with both conditions, presented organ-specific viral infections (mainly pneumonitis, colitis, retinitis, and hepatitis), and 10 patients presented a severe, multiorgan process similar to that described in catastrophic antiphospholipid syndrome-the final diagnosis was hemophagocytic syndrome in 5 cases and disseminated viral infection in 5. Twelve patients died due to infection caused by CMV (n = 5), herpes simplex virus (n = 4), EBV (n = 2), and varicella zoster virus (n = 1). Autopsies were performed in 9 patients and disclosed disseminated herpetic

    2010-01-01

    Background The prevalence of hepatitis C virus (HCV) infection among maintenance hemodialysis (MHD) patients varies among countries and among dialysis units within a single country. The present study aimed to investigate the prevalence and characteristics of HCV infection in MHD patients in a Chinese hemodialysis unit.Methods One hundred and ninety-two patients on MHD for an average of (86.1±30.0) months (range 6-181 months) were enrolled in this cross-sectional study. HCV antibody and HCV-RNA were measured in these MHD patients before hemodialysis by enzyme-linked immunosorbent assay (ELISA) and polymerase chain reaction (PCR) methods.According to the result, all the patients were then divided into two groups: GroupⅠwas positive for HCV antibody and/or HCV-RNA (n=32), and Group Ⅱ was negative for HCV antibody and HCV-RNA (n=160). The following information was obtained for all the patients: socio-demographic data, history of blood transfusions and kidney transplantation, and some laboratory values. The MHD patients who were positive for HCV antibody and/or HCV-RNA were followed for more than three years. The disease activities were graded into "asymptomatic" if alanine aminotransferase (ALT) was less than 40 U/L,"low activities" if ALT was 40-79 U/L, and "high activities" if ALT was equal to or above 80 U/L.Results The prevalence of HCV infection in MHD patients in our dialysis unit in May 2009 was 16.7, which was significantly higher than in general population (3.2%). Among the 32 MHD patients with HCV positive, 20 patients were positive for HCV antibody but negative for HCV-RNA, eight patients were positive both for HCV antibody and HCV-RNA,four patients were negative for HCV antibody but positive for HCV-RNA. Eleven patients had a history of kidney transplantation and 12 had a history of blood transfusion, which were significantly more than among the MHD patients without HCV. Thirty of the 32 MHD patients were asymptomatic. There were no significant

    2008-01-01

    Full Text Available Bacterial infections of the biliary tract are often considered to be an important cause of acute cholangitis. Viral infections of the biliary tract however, are very often mistaken as viral hepatitis. This article highlights various viral causes of common biliary tract infections. Viral cholangitis is both less common and less discussed than viral hepatitis. Hepatotropic viruses (A, B, C, and E are generally regarded as hepatocellular pathogens, yet cholangitic manifestations are now well described in association with these diseases. Systemic viral diseases also lead to cholangitis in varying proportion to hepatitis. Human immunodeficiency virus is associated with protean hepatic complications, including cholangitis due to several causes. Other systemic viruses, most notably those of the herpes virus family, also cause hepatic disease including cholangitis and possibly ductopenia in both immunocompromised and immunocompetent patients.

    AIM: To investigate the viral and host causes of fatty liver in chronic hepatitis B patients and the role of fat deposits in liver damage.METHODS: A total of 164 patients (113 males and 51 females, average age 35±11.3 years, and range 10-62 years) with previously untreated chronic hepatitis B were included in the study. The patients were divided into two groups depending on the result of liver biopsy: group without steatosis (100 patients with <5% hepatosteatosis) and group with steatosis (64 patients with >5% hepatosteatosis). The groups were compared in terms of gender, body mass index (BMI), liver enzymes (ALT, AST, ALP, GGT), cholesterol, triglyceride, HBeAg, viral load, and histological findings. In the group with steatosis, the patients were subdivided depending on the degree of steatosis into mild group (45 patients with 5-24% steatosis), and severe group (19 patients with >25% steatosis). RESULTS: In the group of chronic hepatitis B with steatosis, the mean age, BMI, cholesterol, and triglyceride levels were significantly higher than those in the group without steatosis (P<0.05). Steatosis was found in 53 (46.9%) of male patients and 11 (22%) of female patients (P<0.05). No significant difference was found in the positivity of ALT, AST, ALP, GGT, HBeAg, viral load, histological activity index (HAI) and stage between the two groups (P>0.05). In the group with severe steatosis, the BMI was significantly higher than that in the group with mild steatosis (P<0.05). No significant difference was found in the other parameters between the groups (P>0.05). CONCLUSION: Steatosis in chronic hepatitis B appears to be a result of metabolic factors of the host rather than the effect of viruses. Steatosis is unrelated to the HAI and degree of fibrosis, which are considered as the histological indicators of liver damage.

  6. An overview of animal models for investigating the pathogenesis and therapeutic strategies in acute hepatic failure

    María Jesús Tu(n)ón; Marcelino Alvarez; Jesús M Culebras; Javier González-Gallego

    2009-01-01

    Acute hepatic failure (AHF) is a severe liver injury accompanied by hepatic encephalopathy which causes multiorgan failure with an extremely high mortality rate, even if intensive care is provided. Management of severe AHF continues to be one of the most challenging problems in clinical medicine. Liver transplantation has been shown to be the most effective therapy, but the procedure is limited by shortage of donor organs. Although a number of clinical trials testing different liver assist devices are under way, these systems alone have no significant effect on patient survival and are only regarded as a useful approach to bridge patients with AHF to liver transplantation. As a result, reproducible experimental animal models resembling the clinical conditions are still needed. The three main approaches used to create an animal model for AHF are: surgical procedures, toxic liver injury and infective procedures. Most common models are based on surgical techniques (total/partial hepatectomy, complete/transient devascularization) or the use of hepatotoxic drugs (acetaminophen, galactosamine, thioacetamide, and others), and very few satisfactory viral models are available. We have recently developed a viral model of AHF by meansof the inoculation of rabbits with the virus of rabbit hemorrhagic disease. This model displays biochemical and histological characteristics, and clinical features that resemble those in human AHF. In the present article an overview is given of the most widely used animal models of AHF, and their main advantages and disadvantages are reviewed.

  7. Sequence elements correlating with circulating viral load in genotype 1b hepatitis C virus infection

    The correlation between hepatitis C virus (HCV) genomic sequences and circulating HCV RNA levels was assessed to investigate the genetic elements affecting viral load. The interferon sensitivity-determining region (ISDR) sequence and the serum viral load were strongly correlated in 226 patients examined. Analysis of the entire HCV genome from six patients (three with a high and the others with a low viral load) with similar ISDR sequences identified several candidate residues associated with viral load. The amino acid (aa) sequences of these candidate residues and flanking regions in 67 additional patients revealed that only the residue at aa 962 varied significantly between the HCV patients with low and high serum loads (P 0.042). At this position, alanine was observed more frequently in the patients with a high viral load. In conclusion, our results strongly suggest that serum HCV RNA loads are inversely correlated with amino acid substitutions in the ISDR, and aa 962 was identified as a possible second determinant of serum HCV RNA load

    2002-01-01

    We report a term male infant presenting on postnatal day 1 with fulminant hepatic failure. Described congenital infection, metabolic disorders, and cardiovascular etiologies of acute neonatal liver failure were assessed and eliminated. A liver biopsy on postnatal day 10 showed neonatal giant cell hepatitis (NGCH) with an unusual degree of fibrosis for this early postnatal age. NGCH is a clinical diagnosis of cholestatic disorders of unknown etiology in the newborn, and, to our knowledge, has not been previously associated with immediate neonatal hepatic failure. The giant cell transformation is a common response to a variety of insults and only rarely occurs beyond the neonatal period. Most cases present with cholestatic jaundice and varying degrees of coagulopathy, and, many, as in this case, show progressive resolution. PMID:11948391

    2011-07-01

    Full Text Available Abstract Background and Aims HCV infection may lead to hepatic fibrosis. In this study, we tried to determine whether there is any correlation of HCV genotypes and viral load to the clinical parameters such as ALT, AST, ALP, bilirubin, Hb level, patient's age and gender; and then correlated this association with disease progression in liver biopsy samples. Methods In cross-sectional and observational study, 6048 serum HCV RNA positive patients were chosen. The study consists of 53 months from March 2006 to September 2010. Patients were divided into three cohorts to validate our data. Statistical analysis and correlation of lab parameters with viral factors was determined by using SPSS version 16. Results The most prevalent genotype was 3 (70.9% followed by 1 (13.3% and 4 (7.4%, collectively. During Univariate analysis, in all cohorts; serum bilirubin, ALP, ALT and AAR showed significant correlation with genotypes, however multivariate analysis showed that all genotypes except 4a have no association with host biochemical markers. Disease progression was also independent of all genotypes. Serum ALP, ALT, bilirubin and viremea levels were significantly elevated in patients with genotype 4a. Viral load showed negative association with serum bilirubin (r = -0.112, P = 0.000 and ALP levels (r = -0.098, P = 0.000. We observed positive correlation of ALP and bilirubin levels, while negative associations of viral load with HCV liver disease progression. Conclusion Disease progression seems independent of the genotypes. Relationship between ALP and bilirubin with viral load may be an attractive marker to guess disease progression in patients with hepatitis C.

  10. Epidemiology of hepatitis E virus in China: results from the Third National Viral Hepatitis Prevalence Survey, 2005-2006.

    Zhiyuan Jia

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

  11. Acute hepatitis in a woman following excessive ingestion of an energy drink: a case report

    Waked Alain

    2011-06-01

    Full Text Available Abstract Introduction The consumption of energy drinks has increased significantly. We report the case of a patient who presented to our hospital with jaundice, abdominal pain, and markedly increased liver transaminases likely due to the increased consumption of an energy drink. To the best of our knowledge, this is the first case report in the literature linking the development of acute hepatitis to the consumption of an energy drink. Case presentation A 22-year-old Caucasian woman presented to our hospital with epigastric pain, nausea, vomiting, and low-grade fever. She had been drinking 10 cans of an energy drink daily for two weeks prior to presentation. Her physical examination revealed mild epigastric tenderness. Her initial blood tests revealed elevated alanine aminotransferase, aspartate aminotransferase, and total bilirubin. A computed tomographic scan of the abdomen and pelvis was normal, and the patient was discharged to home. She returned to the Emergency Department of our hospital with worsening pain and new-onset jaundice. This time her physical examination revealed epigastric tenderness and icteric sclera. Her aspartate aminotransferase, alanine aminotransferase, and international normalized ratio were markedly elevated. Further radiological studies were non-specific, and she was admitted to our hospital with a diagnosis of acute hepatitis. Her viral serology and toxicology screens were negative. The patient was treated supportively and was discharged after resolution of her symptoms and a marked decrease in her liver enzymes. Conclusion The development of acute hepatitis in this patient was most likely due to the excessive ingestion of an energy drink, and we speculate that niacin was the culprit ingredient.

  12. A comparative review of HLA associations with hepatitis B and C viral infections across global populations

    Rashmi Singh; Rashmi Kaul; Anil Kaul; Khalid Khan

    2007-01-01

    Hepatitis B (HBV) and hepatitis C (HCV) viral infection or co-infection leads to risk of development of chronic infection, cirrhosis and hepatocellular carcinoma (HCC). Immigration and globalization have added to the challenges of public health concerns regarding chronic HBV and HCV infections worldwide. The aim of this study is to review existing global literature across ethnic populations on HBV and HCV related human leukocyte antigen (HLA) associations in relation to susceptibility, viral persistence and treatment. Extensive literature search was conducted to explore the HLA associations in HBV and HCV infections reported across global populations over the past decade to understand the knowledge status, weaknesses and strengths of this information in different ethnic populations. HLA DR13 is consistently associated with HBV clearance globally. HLADRB1*11/*12 alleles and DQB1*0301 are associated with HBV persistence but with HCV clearance worldwide. Consistent association of DRB1*03 and *07 is observed with HCV susceptibility and non-responsiveness to HBV vaccination across the population. HLA DR13 is protective for vertical HBV and HCV transmission in Chinese and Italian neonates, but different alleles are associated with their susceptibility in these populations. HLA class I molecule interactions with Killer cell immunoglobulin like receptors (KIR) of natural killer (NK) cells modulate HCV infection outcome via regulating immune regulatory cells and molecules. HLA associations with HBV vaccination, interferon therapy in HBV and HCV, and with extra hepatic manifestations of viral hepatitis are also discussed. Systematic studies in compliance with global regulatory standards are required to identify the HLA specific viral epitope, stage specific T cell populations interacting with different HLA alleles during disease progression and viral clearance ofchronic HBV or HCV infections among different ethnic populations. These studies would facilitate stage specific

  14. [Effect of shengmaisan on serum lipid peroxidation in acute viral myocarditis].

    Zhao, M H; Rong, Y Z; Lu, B J

    1996-03-01

    The effect of Shengmaisan (SMS) on 62 acute viral myocarditis patients and its peroxidation damage was studied. The results revealed that the activities of superoxide dismutase (SOD) and glutathione peroxidase (GSH-Px) in blood were decreased and the content of malondialdehyde (MDA) in plasma was increased in acute viral myocarditis patients in comparison with the healthy controls (P SMS group and placebo group. After treatment, both SOD and GSH-Px activities were increased and the level of MDA decreased (P SMS group, while those in placebo group were not changed (P < 0.05). The results suggested that the myocardial damage of viral myocarditis is closely related with lipid peroxidation SMS acts as an effective free radical scavenger and anti-lipid peroxidation drug. SMS could prevent the damage of myocardia and might be taken as one of the effective therapeutic methods in treatment of acute viral myocarditis. PMID:9208534

    Whether pregnancy may influence the replication of hepatitis B virus (HBV) remains unknown. The authors aimed to clarify this issue by observing the kinetics of HBV deoxyribonucleic acid (DNA) and viral antigens in women during and after pregnancy. Total, 371 pregnant women with positive hepatitis B surface antigen (HBsAg) were enrolled. Serial sera collected during and after pregnancy were quantitatively measured for HBV DNA, HBsAg, and hepatitis B e antigen (HBeAg). Total, 34 HBeAg-positive women underwent alanine aminotransferase (ALT) elevation during or after pregnancy; levels of HBV DNA and HBsAg in them showed no obvious change between second trimester or delivery and 7 to 12 months postpartum (P > 0.05). The 337 others had normal alanine aminotransferase levels during pregnancy and postpartum. In 147 HBeAg-positive women with follow-up 7 to 12 months postpartum, the average levels of HBV DNA (>7.0 log10 IU/mL), HBsAg (>4.0 log10 IU/mL), and HBeAg (>3.0 log10 S/CO) were longitudinally constant during pregnancy and postpartum, respectively. In 173 women with follow-up 4.8 years postpartum, neither HBV DNA levels nor antigen titers showed significant difference between second trimester and 4.8 years postpartum, regardless of the HBeAg status. In addition, levels of HBV DNA and viral antigens in second trimester, around delivery, 6 to 8 weeks and 7 to 12 months postpartum showed no marked fluctuations, respectively. Serum levels of HBV DNA and viral antigens in HBsAg-positive women are highly constant during pregnancy and postpartum, regardless of the HBeAg status and alanine aminotransferase levels. This demonstrates that pregnancy has little influence on the HBV replication and antigen expression. PMID:26559291

  19. mTOR in Viral Hepatitis and Hepatocellular Carcinoma: Function and Treatment

    Zhuo Wang

    2014-01-01

    Full Text Available As the fifth most common cancer in men and the eighth most common cancer in women, hepatocellular carcinoma (HCC is the leading cause of cancer-related deaths worldwide, with standard chemotherapy and radiation being minimally effective in prolonging survival. Virus hepatitis, particularly HBV and HCV infection is the most prominent risk factor for HCC development. Mammalian target of rapamycin (mTOR pathway is activated in viral hepatitis and HCC. mTOR inhibitors have been tested successfully in clinical trials for their antineoplastic potency and well tolerability. Treatment with mTOR inhibitor alone or in combination with cytotoxic drugs or targeted therapy drug scan significantly reduces HCC growth and improves clinical outcome, indicating that mTOR inhibition is a promising strategy for the clinical management of HCC.

  20. Kupffer cells hasten resolution of liver immunopathology in mouse models of viral hepatitis.

    Giovanni Sitia

    2011-06-01

    Full Text Available Kupffer cells (KCs are widely considered important contributors to liver injury during viral hepatitis due to their pro-inflammatory activity. Herein we utilized hepatitis B virus (HBV-replication competent transgenic mice and wild-type mice infected with a hepatotropic adenovirus to demonstrate that KCs do not directly induce hepatocellular injury nor do they affect the pathogenic potential of virus-specific CD8 T cells. Instead, KCs limit the severity of liver immunopathology. Mechanistically, our results are most compatible with the hypothesis that KCs contain liver immunopathology by removing apoptotic hepatocytes in a manner largely dependent on scavenger receptors. Apoptotic hepatocytes not readily removed by KCs become secondarily necrotic and release high-mobility group box 1 (HMGB-1 protein, promoting organ infiltration by inflammatory cells, particularly neutrophils. Overall, these results indicate that KCs resolve rather than worsen liver immunopathology.

    2005-01-01

    A 53-year-old man with a history of blood transfusion at the age of 20 was admitted to our hospital because of liver dysfunction. He had bronchial asthma when he was 18 years old, which naturally resolved within 2 years. However, his bronchial asthma recurred at the age of 45 and was treated with oral theophylline. He was diagnosed as having chronic hepatitis C based on the histological and clinical findings, and then interferon (IFN) therapy was administered. The frequency of bronchial asthma attack was gradually decreasing after IFN therapy with marked improvement of hypereosinophilia. He achieved sustained viral response (SVR) and his bronchial asthma did not worsen even after the cessation of IFN. Hepatitis C virus (HCV) infection and IFN therapy were considered in the remission of asthma in this case. HCV infection could be the cause of bronchial asthma, especially in patients with late appearance of asthma.

  3. Detection of antibodies to single-stranded DNA in naturally acquired and experimentally induced viral hepatitis

    A sensitive ''Farr'' assay, utilizing 125I-labelled DNA was developed for detecting antibody to single-stranded DNA (anti-ssDNA). The test was shown to be specific and as sensitive as assays using 14C-labelled DNA, for the detection of antibody in patients with connective tissue diseases. Groups of sera from patients with naturally acquired viral hepatitis and experimentally infected chimpanzees were tested for anti-ssDNA by the 125I assay and by counterimmunoelectrophoresis (CIEP). No consistent pattern was observed with either technique, indicating the elevated levels of this antibody are not as reliable markers of parenchymal liver damage as had been previously suggested

    2002-01-01

    AIM: To investigate the prevalence of hepatitis G virus (HGV) infection and to analyse the homology of different HGV strains in Southern China.METHODS: A total of 1993 sera from different groups in Guangdong, Hong Kong, and Yunnan were detected by reverse transcription polymerase chain reaction (RT-PCR). The nucleotide sequences of 5'untranslated region (5'UTR) derived from 20 strains and NS5 region from 3 strains were determined.RESULTS: The positive rate of HGV RNA was 0.89 % in community population, 2.57 % in blood donors, 17.86 % in intravenous drug abusers, 14.13 % in patients with hemodialysis, 13.66 % in those with hepatocellular carcinoma, 25.30 % in non A-E hepatitis, 7.22 % in hepatitis bone marrow transplantation, respectively. The homology was 90.40-100 % in 5'UTR among different strains, while that of NS5 region was 93.3-94 % in nucleotide sequence, and 97-99.2 % in amino acid sequence.CONCLUSION: These results showed that there was a high incidence of HGV infection in patients from Southern China, being treated for bone marrow transplantation, hepatocellular carcinoma and those on haemodialysis. Furthermore, there was also a high frequency of co-infection of HGV with HBV,HCV, non A-E viral hepatitis and that among intravenous drug abusers. The study also showed that sequence variation in different strains was associated with geographical factors but there was no significant difference in 5'UTR in circulating viruses between different patient groups. Finally, by sequential analysis of viral species present in individual patients over a three months period there was no evidence of sequence variation in the 5' UTR.

  7. Progress in diagnosis of viral hepatitis A, B, C, D and E

    The effective use of new molecular biological techniques towards the reliable diagnosis of HCV and other viral liver infections has been updated in this review. The applications PCR techniques with amplification of reverse transcribed cDNA seems to prove an effective means for assaying HCV infections. A very recent one-stage PCR assay of HCV RNA combined with either liquid hybridization or Southern blot analysis, equal in sensitivity to the nested PCR assay but with sharply reduced potential for contamination appears to be promising. Future further development of reliable and automated RT-PCR assay would be particularly interesting for diagnosis of HCV infections. PCR apparently remains the most useful test for the appraisal of HBV infection in sera-negative patients with liver disease. It has now made possible the confirmation of observations made with the spot blot or Southern blot test and provided access to the nucleotide sequence analysis of these viral mutant forms. The rapidity and simplicity of these viral forms. The rapidity and simplicity of the the newly developed latex agglutination method using ISTA also makes it a viable alternative for the determination of HBsAg. Cloning of HEV, sequencing of the viral genome and expression of recombinant HEV proteins has undoubtedly facilitated significant progress in the development of methods for identification of HEV infection in patients. Recently the availability of specific, more sensitive assays as recombinant-based EIAs has made the diagnosis of hepatitis E very much practicable. (author)

  8. Host and viral factors contributing to CD8+ T cell failure in hepatitis C virus infection

    Christoph Neumann-Haefelin; Hans Christian Spangenberg; Hubert E Blum; Robert Thimme

    2007-01-01

    Virus-specific CD8+ T cells are thought to be the major anti-viral effector cells in hepatitis C virus (HCV)infection. Indeed, viral clearance is associated with vigorous CD8+ T cell responses targeting multiple epitopes. In the chronic phase of infection, HCV-specific CD8+ T cell responses are usually weak, narrowly focused and display often functional defects regarding cytotoxicity, cytokine production, and proliferative capacity. In the last few years, different mechanisms which might contribute to the failure of HCV-specific CD8+ T cells in chronic infection have been identified,including insufficient CD4+ help, deficient CD8+ T cell differentiation, viral escape mutations, suppression by viral factors, inhibitory cytokines, inhibitory ligands, and regulatory T cells. In addition, host genetic factors such as the host's human leukocyte antigen (HLA) background may play an important role in the efficiency of the HCVspecific CD8+ T cell response and thus outcome of infection. The growing understanding of the mechanisms contributing to T cell failure and persistence of HCV infection will contribute to the development of successful immunotherapeutical and -prophylactical strategies.

    2015-01-01

    Full Text Available On the territory of the Russian Federation in the overall structure of acute intestinal infections the proportion of viral diarrhea among children varies from 24 to 78% of cases depending on the season. The acute viral intestinal infections etiological confirmation is performed mainly among patients of infectious hospitals. The prevalence of viral acute intestinal infections in non-infectious hospitals, including infections associated with medical care, remains unclear. Currently estimation of viral component in the acute intestinal infections overall structure mainly consists in determination of rotavirus infection prevalence excluding other pathogens. As the part of viral etiology hospital infections epidemiological surveillance in non-infections children’s hospital the study of acute viral intestinal infections etiological structure and molecular genetics characterization of identified enteric viruses is conducted. The syndrome diagnosis of acute intestinal infections cases was introduced — an identification and evaluation of patients with signs of dysfunction of the gastrointestinal tract, that is not related to the underlying disease. A set of laboratory methods included identification of various intestinal pathogens DNA (RNA by PCR-RT method; genotyping of enteric viruses using sequencing; nucleotide sequence analysis of cDNA fragments using the BLAST software package for identification of closely related strains and an online service for automatic genotyping of noroviruses by Norovirus Genotyping Tool Version 1.0. Alignment of nucleotide sequences and phylogenetic analysis was performed using the software MEGA 5.0. The obtained sequence fragments of the genome was downloaded in GenBank international database. The use of molecular genetics research methods allowed to differentiate viral pathogens of acute intestinal infections and to establish the fact of nosocomial transmission. The proportion of viral etiology acute intestinal

  10. Acute hepatic injury with atorvastatin: An unusual occurrence

    Pinki Vishwakarma

    2014-01-01

    Full Text Available Atorvastatin, a commonly used and well-tolerated hypolipidemic drug, belongs to the class of statins or hydroxymethylglutaryl-coenzyme A reductase inhibitors. Use of atorvastatin may be associated with minor asymptomatic elevations in serum aminotransferases, but clinically significant hepatotoxicity is usually infrequent. Here we present a case of self-limiting clinically apparent acute hepatic injury attributable to atorvastatin occurring at recommended daily dose of 20 mg once a day. This case was postulated to be an unusual idiosyncratic reaction of the drug.

    With about 350 million people chronically infected around the world hepatitis B is a major health problem. Template for progeny HBV synthesis is the viral genome, organized as a minichromosome (cccDNA) inside the hepatocyte nucleus. How viral cccDNA gene expression is regulated by its chromatin structure; more importantly, how the modulation of this structure impacts on viral gene expression remains elusive. Here, we found that the enzyme SetDB1 contributes to setting up a repressed cccDNA chromatin state. This repressive state is activated by the histone lysine demethylase-1 (LSD1). Consistently, inhibiting or reducing LSD1 levels led to repression of viral gene expression. This correlates with the transcriptionally repressive mark H3K9 methylation and reduction on the activating marks H3 acetylation and H3K4 methylation on viral promoters. Investigating the importance of viral proteins we found that LSD1 recruitment to viral promoters was dependent on the viral transactivator protein HBx. Moreover, the histone methyltransferase Set1A and HBx are simultaneously bound to the core promoter, and Set1A expression correlates with cccDNA H3K4 methylation. Our results shed light on the mechanisms of HBV regulation mediated by the cccDNA chromatin structure, offering new therapeutic targets to develop drugs for the treatment of chronically infected HBV patients.

  17. Imaging Based Methods of Liver Fibrosis Assessment in Viral Hepatitis: A Practical Approach

    Hicham Khallafi

    2015-01-01

    Full Text Available Liver fibrosis represents the repair mechanism in liver injury and is a feature of most chronic liver diseases. The degree of liver fibrosis in chronic viral hepatitis infections has major clinical implications and presence of advanced fibrosis or cirrhosis determines prognosis. Treatment initiation for viral hepatitis is indicated in most cases of advanced liver fibrosis and diagnosis of cirrhosis entails hepatology evaluation for specialized clinical care. Liver biopsy is an invasive technique and has been the standard of care of fibrosis assessment for years; however, it has several limitations and procedure related complications. Recently, several methods of noninvasive assessment of liver fibrosis have been developed which require either serologic testing or imaging of liver. Imaging based noninvasive techniques are reviewed here and their clinical use is described. Some of the imaging based tests are becoming widely available, and collectively they are shown to be superior to liver biopsy in important aspects. Clinical utilization of these methods requires understanding of performance and quality related parameters which can affect the results and provide wrong assessment of the extent of liver fibrosis. Familiarity with the strengths and weaknesses of each modality is needed to correctly interpret the results in appropriate clinical context.

  18. Natural Killer Cell Functional Dichotomy: a Feature of Chronic Viral Hepatitis ?

    Mario Umberto Mondelli

    2012-11-01

    Full Text Available NK cells are involved in innate immune responses to viral infections either via direct cytotoxicity which destroys virus-infected cells or production of immunoregulatory cytokines which modulate adaptive immunity and directly inhibit virus replication. These functions are mediated by different NK subpopulations, with cytotoxicity being generally performed by CD56dim NK cells, whereas CD56bright NK cells are mainly involved in cytokine secretion. NK functional defects are usually combined so that impaired degranulation is often associated with deficient cytokine production. Innate immunity is thought to be relevant in the control of hepatitis virus infections such as HBV and HCV, and recent findings reproducibly indicate that NK cells in chronic viral hepatitis are characterized by a functional dichotomy, featuring a conserved or enhanced cytotoxicity and a reduced production of IFN-gamma and TNF-alfa. In chronic HCV infection this appears to be caused by altered IFN-alfa signaling resulting from increased STAT1 phosphorylation, which polarizes NK cells toward cytotoxicity, and a concomitantly reduced IFN-alfa induced STAT4 phosphorylation yielding reduced IFN-gamma mRNA levels. These previously unappreciated findings are compatible on the one hand with the inability to clear HCV and HBV from the liver and on the other they may contribute to understand why these patients are often resistant to interferon (IFNalfa-based therapies.

    There are few reports in the literature of hepatitis as a manifestation of parvovirus B19 infection. We describe a case of parvovirus B19-associated acute hepatitis diagnosed based on a positive serologic test (IgM) and molecular detection of parvovirus B19 DNA in a liver biopsy specimen. Parvovirus B19 infection should be considered in the differential diagnosis of patients presenting with acute hepatitis.

  1. Chronic Hepatitis B with Spontaneous Severe Acute Exacerbation

    Wei-Lun Tsai

    2015-11-01

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

  4. Regulatory T cells control diabetes without compromising acute anti-viral defense☆

    Sachithanantham, Sowbarnika; Dave, Amy; Rodriguez-Calvo, Teresa; Miller, Jacqueline; von Herrath, Matthias

    2016-01-01

    While previous reports have demonstrated the efficacy of regulatory T cell therapy in the prevention of diabetes, systemic immunocompromise and Treg instability remain key safety concerns. Here we examined the influence of induced Treg (iTreg) cell therapy on anti-viral host defense and autoimmune T cell responses during acute viral infection in a murine model of autoimmune diabetes. Protective transfers of iTregs maintained IL-10 expression, and expanded in vivo and controlled diabetes, despite losing FoxP3 expression. Adoptive transfer of iTregs affected neither the primary anti-viral CD8 T cell response nor viral clearance, although a significant and sustained suppression of CD4 T cell responses was observed. Following acute viral clearance, iTregs transferred early suppressed both CD4 and CD8 T cell responses, which resulted in the reversion of diabetes. These observations indicate that iTregs suppress local autoimmune processes while preserving the immunocompetent host's ability to combat acute viral infection. PMID:24858581

  5. A SELEX-screened aptamer of human hepatitis B virus RNA encapsidation signal suppresses viral replication.

    Hui Feng

    Full Text Available BACKGROUND: The specific interaction between hepatitis B virus (HBV polymerase (P protein and the ε RNA stem-loop on pregenomic (pg RNA is crucial for viral replication. It triggers both pgRNA packaging and reverse transcription and thus represents an attractive antiviral target. RNA decoys mimicking ε in P protein binding but not supporting replication might represent novel HBV inhibitors. However, because generation of recombinant enzymatically active HBV polymerase is notoriously difficult, such decoys have as yet not been identified. METHODOLOGY/PRINCIPAL FINDINGS: Here we used a SELEX approach, based on a new in vitro reconstitution system exploiting a recombinant truncated HBV P protein (miniP, to identify potential ε decoys in two large ε RNA pools with randomized upper stem. Selection of strongly P protein binding RNAs correlated with an unexpected strong enrichment of A residues. Two aptamers, S6 and S9, displayed particularly high affinity and specificity for miniP in vitro, yet did not support viral replication when part of a complete HBV genome. Introducing S9 RNA into transiently HBV producing HepG2 cells strongly suppressed pgRNA packaging and DNA synthesis, indicating the S9 RNA can indeed act as an ε decoy that competitively inhibits P protein binding to the authentic ε signal on pgRNA. CONCLUSIONS/SIGNIFICANCE: This study demonstrates the first successful identification of human HBV ε aptamers by an in vitro SELEX approach. Effective suppression of HBV replication by the S9 aptamer provides proof-of-principle for the ability of ε decoy RNAs to interfere with viral P-ε complex formation and suggests that S9-like RNAs may further be developed into useful therapeutics against chronic hepatitis B.

    2011-01-01

    Chronic hepatitis due to any cause leads to cirrhosis and end-stage liver disease. A growing body of literature has also shown that fatty liver due to overweight or obesity is a leading cause of cirrhosis. Due to the obesity epidemic, fatty liver is now a significant problem in clinical practice. Steatosis has an impact on the acceleration of liver damage in patients with chronic hepatitis due to other causes. An association between hepatitis C virus (HCV) infection, steatosis and the onset of insulin resistance has been reported. Insulin resistance is one of the leading factors for severe fibrosis in chronic HCV infections. Moreover, hyperinsulinemia has a deleterious effect on the management of chronic HCV. Response to therapy is increased by decreasing insulin resistance by weight loss or the use of thiazolidenediones or metformin. The underlying mechanisms of this complex interaction are not fully understood. A direct cytopathic effect of HCV has been suggested. The genomic structure of HCV (suggesting that some viral sequences are involved in the intracellular accumulation of triglycerides), lipid metabolism, the molecular links between the HCV core protein and lipid droplets (the core protein of HCV and its transcriptional regulatory function which induce a triglyceride accumulation in hepatocytes) and increased neolipogenesis and inhibited fatty acid degradation in mitochondria have been investigated.

    The inhibitory receptor, Programmed Death 1 (PD-1), and its ligands (PD-L1/PD-L2) are thought to play a role in immune surveillance during chronic viral infection. The contribution of the receptor/ligand pair during an acute infection is less understood. To determine the role of PD-L1 and PD-L2 during acute ocular herpes simplex virus type 1 (HSV-1) infection, HSV-1-infected mice administered neutralizing antibody to PD-L1 or PD-L2 were assessed for viral burden and host cellular immune respo...

    Integration of DNA viruses into the human genome plays an important role in various types of tumors, including hepatitis B virus (HBV)–related hepatocellular carcinoma. However, the molecular details and clinical impact of HBV integration on either human or HBV epigenomes are unknown. Here, we show that methylation of the integrated HBV DNA is related to the methylation status of the flanking human genome. We developed a next-generation sequencing-based method for structural methylation analysis of integrated viral genomes (denoted G-NaVI). This method is a novel approach that enables enrichment of viral fragments for sequencing using unique baits based on the sequence of the HBV genome. We detected integrated HBV sequences in the genome of the PLC/PRF/5 cell line and found variable levels of methylation within the integrated HBV genomes. Allele-specific methylation analysis revealed that the HBV genome often became significantly methylated when integrated into highly methylated host sites. After integration into unmethylated human genome regions such as promoters, however, the HBV DNA remains unmethylated and may eventually play an important role in tumorigenesis. The observed dynamic changes in DNA methylation of the host and viral genomes may functionally affect the biological behavior of HBV. These findings may impact public health given that millions of people worldwide are carriers of HBV. We also believe our assay will be a powerful tool to increase our understanding of the various types of DNA virus-associated tumorigenesis. PMID:25653310

    2012-01-01

    Hepatitis delta virus (HDV) is a defective RNA virus that requires HBsAg for replication and transmission. It can cause acute or chronic hepatitis. Chronic infection with HDV is one of the most severe and difficult to treat forms of viral hepatitis. It has been estimated that there is a total of 15-20 million HDV carriers in the world. This review focuses on two fundamental aspects of HDV infection. On the one hand, epidemiological data are summarized, which are essential to understand the re...

    Hepatitis E virus (HEV) induces acute hepatitis in humans with a high fatality rate in pregnant women. There is a need for anti-HEV research to understand the assembly process of HEV native capsid. Here, we produced a large virion-sized and a small T=1 capsid by expressing the HEV capsid protein in insect cells with and without the N-terminal 111 residues, respectively, for comparative structural analysis. The virion-sized capsid demonstrates a T=3 icosahedral lattice and contains RNA fragment in contrast to the RNA-free T=1 capsid. However, both capsids shared common decameric organization. The in vitro assembly further demonstrated that HEV capsid protein had the intrinsic ability to form decameric intermediate. Our data suggest that RNA binding is the extrinsic factor essential for the assembly of HEV native capsids.

    2016-01-01

    Liver biopsy evaluation plays a critical role in management of patients with viral hepatitis C. In patients with acute viral hepatitis, a liver biopsy, though uncommonly performed, helps to rule out other non-viral causes of deranged liver function. In chronic viral hepatitis C, it is considered the gold standard in assessment of the degree of necroinflammation and the stage of fibrosis, to help guide treatment and determine prognosis. It also helps rule out any concomitant diseases such as s...

  16. Interleukins as one of possible markers for early diagnosis of viral hepatitis c at first year old children

    T. A. Kirsanova

    2014-09-01

    Full Text Available The article presents the results of the research of improvement one of possible methods of early diagnostics of viral hepatitis C at first-year old children, who born from mothers with chronic viral hepatitis C, in blood anti-HCV IgG are revealed, based on the study of maintenance of blood serum interleukins in dynamic observation of children. Proven that for children with maternal antibodies to virus of hepatitis C gradual decrease of titer of anti-HCV IgG is marked on background of physiological maintenance of interleukins or their level doesn’t exceed the normal in 1,5-2 time. For children with own antibodies of anti-HCV IgG a few months prior to viral RNA and synthesis of anti-HCV IgМ in blood is observed increase of level of interleukins, especially ІL-6. At children with their own anti-HCV IgG antibodies for few months before the synthesis of anti-HCV IgM are increased levels of interleukins, particularly IL-6. Thus, the serum interleukins response is an important criterion in determining the conditioning of antibodies to virus hepatitis C and earlier diagnosis of viral hepatitis C for first-year old children. Among all interleukins the most specific early marker of viral hepatitis C is IL-6. To clarify the belonging antibodies and more early diagnostics viral hepatitis С to all first-year old children, who born from mothers with chronic viral hepatitis С, and whose blood had educed antibodies of anti-HCV IgG, it is recommended the more careful monitoring of titer of antibodies of class IgМ, IgG, PCR and level of interleukins in serum (especially ІL- 6.

  17. The Role of Serum Leptin and IL-6 Levels in Post Viral Hepatitis Cirrhotic patients

    Chronic liver disease is characterized by numerous metabolic alterations resulting in the clinical picture of malnutrition or even cachexia and contributing to complications such as hepatic encephalopathy and ascites. Leptin is a hormone that plays an important role in regulating energy intake and expenditure including appetite and metabolism. Interleukin-6 (IL-6), on the other hand, is generally considered to be one of the important cytokines that regulate immunologic and metabolic actions. The aim of the present study was to investigate serum leptin and IL-6 levels in liver cirrhosis, as well as to determine their levels in relation to liver functions and lipid profile. This study was conducted on 25 patients with post- viral hepatic cirrhosis compared to 20 healthy matched individuals served as controls with the same age and sex. The severity of the disease assessed with Child-Pugh criteria yielded 8 patients (3 women, 5 men) with stage A, 10 patients (4 women, 6 men) with stage B and 7 patients (2 women, 5 men) with stage C. Compared to controls, body mass index (BMI) was decreased and reached statistical significance in group C liver cirrhosis (P< 0.05). Also, serum leptin level was highly significantly decreased in the three groups, while IL-6 level showed highly significant increase. Leptin level negatively correlated with aspartate aminotransferase (AST), alanine aminotransferase (ALT) and total bilirubin and positively correlated with serum albumin, triglycerides (TG), cholesterol and low density lipoprotein (LDL). In contrast, serum IL-6 level positively correlated with parameters of liver functions and negatively correlated with parameters of lipid profile. Additionally, there was highly significant negative correlation between serum leptin and IL-6 levels (P < 0.001) in post-hepatic cirrhotic patients. We concluded that leptin and IL-6 have important role in diagnosis and prognosis of patients with post-hepatic liver cirrhosis

  19. Female sex and IL28B, a synergism for spontaneous viral clearance in hepatitis C virus (HCV seroconverters from a community-based cohort.

    Charlotte H B S van den Berg

    Full Text Available BACKGROUND & AIMS: Since acute hepatitis C virus (HCV infection is often asymptomatic, it is difficult to examine the rate and determinants of spontaneous clearance. Consequently, these studies are subject to bias, which can potentially lead to biased rates of viral clearance and risk estimates. We evaluated determinants of spontaneous HCV clearance among HCV seroconverters identified in a unique community-based cohort. METHODS: Subjects were 106 drug users with documented dates of HCV seroconversion from the Amsterdam Cohort Study. Logistic regression was used to examine sociodemographic, behavioral, clinical, viral and host determinants, measured around acute infection, of HCV clearance. RESULTS: The spontaneous viral clearance rate was 33.0% (95% confidence interval (CI 24.2-42.8. In univariate analyses female sex and fever were significantly associated with spontaneous clearance. The favorable genotypes for rs12979860 (CC and rs8099917 (TT were associated with spontaneous clearance, although borderline significant. In multivariate analysis, females with the favorable genotype for rs12979860 (CC had an increased odds to spontaneously clear HCV infection (adjusted OR 6.62, 95% 2.69-26.13, whereas females with the unfavorable genotype were as likely as men with the favorable and unfavorable genotype to clear HCV. Chronic Hepatitis B infection and absence of HIV coinfection around HCV seroconversion also favor HCV clearance. CONCLUSIONS: This study shows that co-infection with HIV and HBV and genetic variation in the IL28B region play an important role in spontaneous clearance of HCV. Our findings suggest a possible synergistic interaction between female sex and IL28B in spontaneous clearance of HCV.

  20. Acute psychosis followed by fever: Malignant neuroleptic syndrome or viral encephalitis?

    2014-01-01

    Full Text Available Introduction. Neuroleptic malignant syndrome is rare, but potentially fatal idiosyncratic reaction to antipsychotic medications. It is sometimes difficult to diagnose some clinical cases as neuroleptic malignant syndrome and differentiate it from the acute viral encephalitis. Case report. We reported a patient diagnosed with acute psychotic reaction which appeared for the first time. The treatment started with typical antipsychotic, which led to febrility. The clinical presentation of the patient was characterised by the signs and symptoms that might have indicated the neuroleptic malignant syndrome as well as central nervous system viral disease. In order to make a detailed diagnosis additional procedures were performed: electroencephalogram, magnetic resonance imaging of the head, lumbar puncture and a serological test of the cerebrospinal fluid. Considering that after the tests viral encephalitis was ruled out and the diagnosis of neuroleptic malignant syndrome made, antipsychotic therapy was immediately stopped. The patient was initially treated with symptomatic therapy and after that with atypical antipsychotic and electroconvulsive therapy, which led to complete recovery. Conclusion. We present the difficulties of early diagnosis at the first episode of acute psychotic disorder associated with acute febrile condition. Concerning the differential diagnosis it is necessary to consider both neuroleptic malignant syndrome and viral encephalitis, i.e. it is necessary to make the neuroradiological diagnosis and conduct cerebrospinal fluid analysis and blood test. In neuroleptic malignant syndrome treatment a combined use of electroconvulsive therapy and low doses of atypical antipsychotic are confirmed to be successful.

    Data concerning the efficacy of PEG-IFN alpha 2a plus ribavirin treatment in treatment-naive, genotype 4-infected chronic hepatitis C (CHC) patients from Europe are limited. Hence the aim of this study was to investigate the viral kinetics as well as the sustained virological response (SVR) rates and their predictors, in these patients. One hundred and twenty-three patients were retrospectively analysed. Early (EVR) and late virological response (LVR) was confirmed by undetectable (Egyptian patients (P = 0.613), in whom the only independent predictor of SVR was the absence of cirrhosis (P = 0.004). LVR seems to be a better predictor of SVR than EVR in the vast majority of genotype 4-infected CHC patients, irrespective of ethnicity and all the other baseline parameters. PMID:19413697

There was greater incidence of the desease in the Condado health area, the bad handling of the solid residue and liquids influenced in the morbility of the desease.

  3. Detection of antibodies to single-stranded DNA in naturally acquired and experimentally induced viral hepatitis

    Gust, I.D.; Feinstone, S.M.; Purcell, R.H.; Alter, H.J.

    1980-01-01

    A sensitive ''Farr'' assay, utilizing /sup 125/I-labelled DNA was developed for detecting antibody to single-stranded DNA (anti-ssDNA). The test was shown to be specific and as sensitive as assays using /sup 14/C-labelled DNA, for the detection of antibody in patients with connective tissue diseases. Groups of sera from patients with naturally acquired viral hepatitis and experimentally infected chimpanzees were tested for anti-ssDNA by the /sup 125/I assay and by counterimmunoelectrophoresis (CIEP). No consistent pattern was observed with either technique, indicating the elevated levels of this antibody are not as reliable markers of parenchymal liver damage as had been previously suggested.

  4. An accurate two-phase approximate solution to the acute viral infection model

    Perelson, Alan S [Los Alamos National Laboratory

    2009-01-01

    During an acute viral infection, virus levels rise, reach a peak and then decline. Data and numerical solutions suggest the growth and decay phases are linear on a log scale. While viral dynamic models are typically nonlinear with analytical solutions difficult to obtain, the exponential nature of the solutions suggests approximations can be found. We derive a two-phase approximate solution to the target cell limited influenza model and illustrate the accuracy using data and previously established parameter values of six patients infected with influenza A. For one patient, the subsequent fall in virus concentration was not consistent with our predictions during the decay phase and an alternate approximation is derived. We find expressions for the rate and length of initial viral growth in terms of the parameters, the extent each parameter is involved in viral peaks, and the single parameter responsible for virus decay. We discuss applications of this analysis in antiviral treatments and investigating host and virus heterogeneities.

    2014-12-01

    Full Text Available Introduction:There is scarce information regarding clinical evolution of HBV infection in renal transplant patients.Aims:To evaluate the prevalence of acute exacerbation in HBV-infected renal transplant patients and its association with the time after transplantation, presence of viral replication, clinical evolution, and use of antiviral prophylaxis.Materials and methods:HBV infected renal transplant patients who underwent regular follow-up visits at 6-month intervals were included in the study. The criteria adopted to characterize exacerbation were: ALT >5 × ULN and/or >3 × baseline level. Predictive factors of exacerbation evaluated were age, gender, time on dialysis, type of donor, post-transplant time, ALT, HBeAg, HBV-DNA, HCV-RNA, immunosuppressive therapy, and use of antiviral prophylaxis.Results:140 HBV-infected renal transplant patients were included (71% males; age 46 ±10 years; post-renal transplant time 8 ±5 years. During follow-up, 25% (35/140 of the patients presented exacerbation within 3.4 ±3 years after renal transplant. Viral replication was observed in all patients with exacerbation. Clinical and/or laboratory signs of hepatic insufficiency were present in 17% (6/35 of the patients. Three patients died as a consequence of liver failure. In univariate analysis variables associated with exacerbation were less frequent use of prophylactic/preemptive lamivudine and of mycophenolate mofetil. Lamivudine use was the only variable independently associated with exacerbation, with a protective effect.Conclusions:Acute exacerbation was a frequent and severe event in HBV-infected renal transplant patients. Prophylactic/preemptive therapy with antiviral drugs should be indicated for all HBsAg-positive renal transplant patients.

  6. PHENOTYPE AND FUNCTIONS OF DENDRITIC CELLS IN PATIENTS WITH CHRONIC VIRAL HEPATITIS

    O. Yu. Leplina

    2014-07-01

    Full Text Available Abstract. Phenotypic and functional features of IFNα-induced dendritic cells (DCs were studied in patients with chronic viral hepatitis B and C (HBV and HCV, and in cases with hepatitis-related liver cirrhosis (LC. It was shown that DCs are characterized by delayed differentiation/maturation which was more pronounced in HCV patients, as well as in all patients with LC, regardless of virus type. DCs from HBV patients were characterized by increased IFNγ secretion. Transformation of HBV-infection to LC is accompanied by a moderate decrease in IFNγ production, combined with a significantly increased IL-10 secretion. Irrespectively of fibrosis severity, the IFNα-induced DCs of HCV patients displayed active IL-10 synthesis. Moreover, ability of DCs to secrete IFNγ was significantly decreased only in cases of fibrosis-complicated HCV-infection. With respect to TNFα and IL-4 production levels, DCs of the patients were compatibe to normal donor cells, independently on the type of virus, or fibrosis severity. DCs from HBV- and HCV-patients were characterized by intact allostimulatory and Th1/Th2-stimulatory activities in MLC. At the same time, IFNα-induced DCs exhibited suppression of allostimulatory and increase in Th2-polarizing activity upon LC development, both in HBV and HCV patients.

    2003-01-01

    Full Text Available OBJECTIVE: To assess school teachers' level of knowledge on prevention of viral hepatitis (VH. MATERIAL AND METHODS: A cross-sectional study was conducted in three cities of Brazil, from August to November of 1999. The sample was composed of 360 subjects: 334 women and 26 men, 81 (22.5% from Belém, 123 (34.2% from Natal and 156 (43.3% from Rio de Janeiro. Cultural differences in knowledge were identified using a questionnaire to classify, according to semantic content, categories of transmission and preventive practices. Responses were scored as right or wrong. Data were tabulated and analyzed using EPIINFO 6.04 and open answers were classified according to semantic content. Comparison of the answer frequencies between cities was done through the chi-square test. RESULTS: Transmission category (TC (n=837 answers and prevention category (PC (n=771 answers "food-and waterborne" transmission items were the most frequently mentioned (40%. For TC, "food-and waterborne" answers were followed by "bloodborne" (16%, "inadequate knowledge" (9%, "possible causes of hepatic disease" (9%, and "sexual transmission" (7% answers. For PC items, "food-and waterborne" answers were followed by "general aspects of prevention" (13%, "immunization" (9%, "quality of health services" (8% and "sexual prevention" (5% items. "Right" scores for transmission mechanisms and prevention practices varied from zero to 80%. CONCLUSIONS: Study findings suggest that investments should be made to disseminate appropriate knowledge on VH prevention, mainly addressing sexual transmission and intravenous drug use.

  8. A hepatocellular carcinoma cell line producing mature hepatitis B viral particles

    Current in vitro models for hepatitis B virus (HBV) are based on human hepatoblastoma cell lines transfected with HBV genome. The objective of this work was to develop an in vitro, hepatocellular carcinoma (HCC)-based system supporting HBV full replication and producing mature viral particles. The FLC4 human HCC cell line was stably transfected with a plasmid carrying a head-to-tail dimer of the adwHBV genome. One of the clones, FLC4A10II, exhibited prolonged expression of HBV, as was demonstrated by secreted levels of HBsAg, HBeAg, and HBV DNA in the culture medium of the growing cells. Furthermore, the cells produced HBV particles that were detected by a cesium chloride density gradient performed on the culture medium. Analysis by Southern blot revealed that HBV DNA has integrated into the FLC4A10II cell genome. The presence of HBV in the FLC4A10II cells did not cause alterations in cell morphology and the cells continued to resemble mature hepatocytes. They do exhibit a high mitotic activity. The new HBV stably transfected cell line, FLC4A10II, can serve as an important tool for further exploration of HBV host-pathogen interaction, viral life cycle, and for assessing new antiviral agents

  9. Two distinct subtypes of hepatitis B virus-related acute liver failure are separable by quantitative serum immunoglobulin M anti-hepatitis B core antibody and hepatitis B virus DNA levels

    2012-01-01

    Hepatitis B virus (HBV)-related acute liver failure (HBV-ALF) may occur after acute HBV infection (AHBV-ALF) or during an exacerbation of chronic HBV infection (CHBV-ALF). Clinical differentiation of the two is often difficult if a previous history of HBV is not available. Quantitative measurements...... of immunoglobulin M (IgM) anti-hepatitis B core antibody (anti-HBc) titers and of HBV viral loads (VLs) might allow the separation of AHBV-ALF from CHBV-ALF. Of 1,602 patients with ALF, 60 met clinical criteria for AHBV-ALF and 27 for CHBV-ALF. Sera were available on 47 and 23 patients, respectively.......025). Twenty percent (12 of 60) of the AHBV-ALF group had no hepatitis B surface antigen (HBsAg) detectable on admission to study, wheras no CHBV-ALF patients experienced HBsAg clearance. Rates of transplant-free survival were 33% (20 of 60) for AHBV-ALF versus 11% (3 of 27) for CHBV-ALF (P = 0...

    Full Text Available Hepatitis B virus and C viruses (HBV and HCV, respectively infects the liver which results in a wide range of disease outcomes. Worldwide, over 7% (350 million and 3% (170 million people are chronically infected with HBV and HCV, respectively.[1] HBV is transmitted through exposure to infective blood, semen, and other body fluids or through infected mothers to infants at the time of birth. Transmission may also occur through transfusions of HBV-contaminated blood and blood products, contaminated injections during medical procedures, and through transfusions of HCV-contaminated blood and blood products, contaminated injections during medical procedures, and through injection drug use. Sexual transmission is also possible.[2] Individuals with chronic hepatitis B and/or C virus infection remain infectious to others and are at risk of serious liver disease such as liver cirrhosis or hepatocellular cancer (HCC. [3,4] Study reports revealed that HBV and/or HCV infections are the major causes of morbidity and mortality in HIV positive population related to liver cirrhosis and hepatocellular carcinoma.[5,6] Though studies on the prevalence of HBV (rarely on HCV among tribal population in India were available[7,8], there is no recent reports from southern part of India. Hence, the present study was conducted to assess the prevalence of HBV and HCV among tribal population in Kotagiri, Nilgiris. After obtaining the informed consent, blood samples (5 ml each from a total of 196 participants (103 males and 93 females were collected and sera were separated on site. Samples which showed positive for HBsAg and anti-HCV by rapid test were confirmed by ELISA technique using commercial kits Reliable Pro-detect Biomedical Ltd, India and Erba Lisa, Germany, respectively. Of the 196 individuals screened, none of them was positive for the viral markers. Several studies from India reported varying range of HBsAg and anti-HCV positivity among general and tribal

  12. Coincidence of acute Brucella hepatitis and dengue fever or serologic cross-reactivity?

    Bzeizi Khalid

    2010-01-01

    Full Text Available Hepatic involvement in brucellosis is not uncommon since 10-20% of patient infected with brucella species can have abnormal liver function tests. The usual presentation of brucella hepatitis is in the form of chronic granulomatous hepatitis with mild to moderate elevation of liver enzymes, while acute hepatitis is rare. We report a young patient who presented with acute brucella-induced hepatitis and co-infection with dengue hemorrhagic virus resulting in severe elevation of liver enzymes and absence of granuloma on histology. His mother also simultaneously tested positive for both infections. The patient responded well to anti-brucella therapy with normalization of his liver profile. We discuss, herein, the hepatic involvement of these two infections and discuss the possible serological cross-reactivity between brucella and dengue fever virus.

  13. A child with acute encephalopathy associated with quadruple viral infection

    2015-04-01

    Full Text Available infection does not always result in AE. The risk factors for developing infantile AE upon such infection remain to be determined. Here we report an infant with AE coinfected with human herpesvirus 6 (HHV-6 and three picornaviruses: coxsackievirus A6 (CVA6, enterovirus D68 (EV-D68, and human parechovirus (HPeV. EV-D68 was vertically transmitted to the infant from his mother. CVA6 and HPeV were likely transmitted to the infant at the nursery school. HHV-6 might have been re-activated in the patient. It remains undetermined which pathogen played the central role in the AE pathogenesis. However, active, simultaneous infection by four viruses likely evoke a cytokine storm, leading to the pathogenesis of AE. Conclusion: Infant cases with active quadruple infection by potentially AE-causing viruses have seldom been reported, partly because systematic nucleic acid-based laboratory tests on picornaviruses are not common. We propose that simultaneous viral infection may serve as a risk factor for the development of AE.

    Full Text Available Introduction and objectives: prevalence of viral hepatitis (B and C changes geographically. Our aim was to determinate the prevalence of hepatitis B (HBV and hepatitis C virus (HCV serological markers in healthy working population and to describe the epidemiological characteristics associated to its presence. Methods: blood samples and epidemiological data of 5,017 healthy workers from Murcia and Madrid were recorded prospectively. Results: a total of 5,017 healthy volunteers participated. Mean age 39 ± 11 years, men predominance (73 %. Prevalence of serological markers of HCV and HBV was 0.6 % and 0.7 %. Age of patients with HCV antibody was significantly higher (43 ± 9 years vs. 39 ± 11 years; p = 0.03. We observed significant differences in liver test values (alanine aminotransferase [ALT] 64 ± 56 IU/L vs. 28 ± 20 IU/L; p < 0.001; aspartate aminotransferase [AST] (51 ± 45 IU/L vs. 23 ± 12 IU/L; p < 0.001 and in gamma-glutamyltransferase (GGT value (104 ± 122 IU/L vs. 37 ± 46 IU/L; p < 0.001. The presence of HCV antibody was related significantly to previous transfusion (13 % vs. 5 %; p = 0.03, tattoos (29 % vs. 13 %; p < 0.01, intravenous drug addiction (13 % vs. 0.2 %; p < 0.001 and coexistence with people with positive HCV antibody (16 % vs. 4 %; p < 0.001. In HBV no differences in basal characteristics were observed with exception in AST values (29 ± 15 IU/L vs. 23 ± 12 IU/L; p < 0.01. Hepatitis B surface antigen (HBsAg was related significantly to previous transfusion (15 % vs. 5 %; p < 0.01, tattoos (26 % vs. 14 %; p = 0.04 and coexistence with people with positive HBsAg (17 % vs. 4 %; p < 0.001. Conclusions: prevalence of serological markers in healthy working population is low. Risk factors for infection were previous transfusion and tattoos. Intravenous drug addiction was only a risk factor in HCV.

    2016-07-01

    Hepatitis E virus (HEV) is an emerging infectious agent in developed countries. HEV genotypes 1 (G1) and 3 (G3) have been identified in environmental and clinical samples in Europe. In Israel, the overall prevalence of anti-HEV IgG antibodies was found to be 10.6%; however, reports of HEV infection are scarce. In this study, the presence of HEV in Israel was investigated using 169 sewage samples from 32 treatment facilities and 49 samples from acute hepatitis patients, all collected between 2013 and 2015. Fourteen sewage samples, from Haifa (11/18 samples), Tel Aviv (2/29 samples), and Beer Sheva (1/17 samples), regions with good sanitary conditions and middle-high socioeconomic populations, were HEV positive. Among the patient samples, 6.1% (3/49) were HEV positive, all returning travelers from India. Genotype analysis revealed G1 HEV in patients and G3 HEV sequences in sewage. Evidence that HEV could be establishing itself in our region may justify more active surveillance to monitor its spread. PMID:27246446

    2009-01-01

    BACKGROUND:Acute-on-chronic liver failure (ACLF) is common in Bangladesh. Acute viral E hepatitis is sporadically encountered in this country each year, with a rising incidence in the rainy season. This study aimed to identify the etiology of ACLF in Bangladesh. METHODS:In this retrospective study, 69 ACLF patients were included. They presented to our department at the Bangabandhu Sheikh Mujib Medical University in Dhaka. History of diseases was recorded and appropriate investigations were conducted in all patients. RESULTS:Acute hepatitis E virus (HEV) infection was positive in 21.7% (15/69) of the patients, while 14.5%(10/69) had septicemia. Upper gastrointestinal tract hemorrhage was seen in 4.3% of the patients (3/69), while another 4.3% (3/69) had a positive history for alcohol or drugs. None of the patients tested positive for hepatitis A virus infection and no evidence of hepatitis B virus lfare was found in any patient. No speciifc cause for ACLF could be identiifed. CONCLUSIONS:Acute HEV infection is a leading cause of ACLF in Bangladesh. Many patients were thought to have decompensation of cirrhosis, but subsequently were recognized as having ACLF by a retrospective review according to the deifnition of the Asian Paciifc Association for the Study of the Liver Working Party Meeting on ACLF in New Delhi in early 2008.

  1. Analysis of precore/core covariances associated with viral kinetics and genotypes in hepatitis B e antigen-positive chronic hepatitis B patients.

    Chun-Pei Cheng

    Full Text Available Hepatitis B virus (HBV is one of the most common DNA viruses that can cause aggressive hepatitis, cirrhosis and hepatocellular carcinoma. Although many people are persistently infected with HBV, the kinetics in serum levels of viral loads and the host immune responses vary from person to person. HBV precore/core open reading frame (ORF encoding proteins, hepatitis B e antigen (HBeAg and core antigen (HBcAg, are two indicators of active viral replication. The aim of this study was to discover a variety of amino acid covariances in responses to viral kinetics, seroconversion and genotypes during the course of HBV infection. A one year follow-up study was conducted with a total number of 1,694 clones from 23 HBeAg-positive chronic hepatitis B patients. Serum alanine aminotransferase, HBV DNA and HBeAg levels were measured monthly as criteria for clustering patients into several different subgroups. Monthly derived multiple precore/core ORFs were directly sequenced and translated into amino acid sequences. For each subgroup, time-dependent covariances were identified from their time-varying sequences over the entire follow-up period. The fluctuating, wavering, HBeAg-nonseroconversion and genotype C subgroups showed greater degrees of covariances than the stationary, declining, HBeAg-seroconversion and genotype B. Referring to literature, mutation hotspots within our identified covariances were associated with the infection process. Remarkably, hotspots were predominant in genotype C. Moreover, covariances were also identified at early stage (spanning from baseline to a peak of serum HBV DNA in order to determine the intersections with aforementioned time-dependent covariances. Preserved covariances, namely representative covariances, of each subgroup are visually presented using a tree-based structure. Our results suggested that identified covariances were strongly associated with viral kinetics, seroconversion and genotypes. Moreover

    Bronchiolitis may be diagnosed on the basis of clinical signs and symptoms. In a young child, the diagnosis can be made on the clinical pattern of wheezing and hyperinflation. Clinical symptoms and signs typically start with an upper respiratory prodrome, including rhinorrhoea, low-grade fever, cough and poor feeding, followed 1 - 2 days later by tachypnoea, hyperinflation and wheeze as a consequence of airway inflammation and air trapping.The illness is generally self limiting, but may become more severe and include signs such as grunting, nasal flaring, subcostal chest wall retractions and hypoxaemia. The most reliable clinical feature of bronchiolitis is hyperinflation of the chest, evident by loss of cardiacdullness on percussion, an upper border of the liver pushed down to below the 6th intercostal space, and the presence of a Hoover sign(subcostal recession, which occurs when a flattened diaphragm pulls laterally against the lower chest wall).Measurement of peripheral arterial oxygen saturation is useful to indicate the need for supplemental oxygen. A saturation of <92% at sea level and 90% inland indicates that the child has to be admitted to hospital for supplemental oxygen. Chest radiographs are generally unhelpful and not required in children with a clear clinical diagnosis of bronchiolitis.Blood tests are not needed routinely. Complete blood count tests have not been shown to be useful in diagnosing bronchiolitis or guiding its therapy. Routine measurement of C-reactive protein does not aid in management and nasopharyngeal aspirates are not usually done.Viral testing adds little to routine management. Risk factors in patients with severe bronchiolitis that require hospitalisation and may even cause death, include prematurity, congenital heart disease and congenital lung malformations.

  3. Ultrasonographic Findings of the Gallbladder in Patients with Acute Hepatitis A: Do They Have Clinical Relevance?

    To determine the association of gallbladder (GB) abnormalities on ultrasonography (US) of patients with acute hepatitis A with demographic, clinical, and biochemical factors, and with other US findings. This retrospective study was approved by our institutional review board, which waived the requirement for informed consent. We retrospectively evaluated 152 consecutive patients with acute hepatitis A who underwent US. The diagnosis of acute hepatitis A was made during acute illness by demonstrating anti- HAV of the IgM class. US images were reviewed simultaneously by two abdominal radiologists and a consensus was reached for GB wall thickening, GB collapse, lymphadenopathy, and hepatic echogenicity. The associations between demographic, clinical, biochemical, and US findings and GB wall thickening or collapse were then assessed. GB wall thickening was present in 123 (81%) and GB collapse in 96 (63%) of the 152 patients. Total bilirubin level and GB collapse differed significantly (p < 0.05) between patients with and without GB wall thickening. Gender ratio, total and peak total bilirubin level, and GB wall thickness differed significantly (p < 0.05) between patients with and without GB collapse. Multivariate analysis showed that GB wall thickening was associated with GB collapse and vice versa. GB wall thickening and GB collapse are common US abnormalities associated with each other in patients with acute hepatitis A. However, GB wall thickening or collapse is not associated with any demographic, clinical, or biochemical factors, or with other US findings, in patients with acute hepatitis A.

  7. Coevolution analysis of Hepatitis C virus genome to identify the structural and functional dependency network of viral proteins.

    Champeimont, Raphaël; Laine, Elodie; Hu, Shuang-Wei; Penin, Francois; Carbone, Alessandra

    2016-01-01

    A novel computational approach of coevolution analysis allowed us to reconstruct the protein-protein interaction network of the Hepatitis C Virus (HCV) at the residue resolution. For the first time, coevolution analysis of an entire viral genome was realized, based on a limited set of protein sequences with high sequence identity within genotypes. The identified coevolving residues constitute highly relevant predictions of protein-protein interactions for further experimental identification of HCV protein complexes. The method can be used to analyse other viral genomes and to predict the associated protein interaction networks. PMID:27198619

    2011-01-01

    BACKGROUND: Acute hepatic failure (AHF) is a devastating clinical syndrome with a high mortality rate. The outcome of AHF varies with etiology, but liver transplantation (LT) can significantly improve the prognosis and survival rate of such patients. This study aimed to detect the role of LT and artificial liver support systems (ALSS) for AHF patients and to analyze the etiology and outcome of patients with this disease. METHODS: A retrospective analysis was made of 48 consecutive patients with AHF who fulfilled the Kings College Criteria for LT at our center. We analyzed and compared the etiology, outcome, prognosis, and survival rates of patients between the transplantation (LT) group and the non-transplantation (N-LT) group. RESULTS: AHF was due to viral hepatitis in 25 patients (52.1%; hepatitis B virus in 22), drug or toxic reactions in 14 (29.2%; acetaminophen in 6), Wilson disease in 4 (8.3%), unknown reasons in 3 (6.3%), and miscellaneous conditions in 2 (4.2%). In the LT group, 36 patients (7 underwent living donor LT, and 29 cadaveric LT) had an average model for end-stage liver disease score (MELD) of 35.7. Twenty-eight patients survived with good graft function after a follow-up of 27.3± 4.5 months. During the waiting time, 6 patients were treated with ALSS and 2 of them died during hospitalization. The 30-day, 12-month, and 18-month survival rates were 77.8%, 72.2%, and 66.7%, respectively. In the N-LT group, 12 patients had an average MELD score of 34.5. Four patients were treated with ALSS and all died during hospitalization. The 90-day and 1-year survival rates were only 16.7% and 8.3%, respectively. CONCLUSIONS: Hepatitis is the most prominent cause of AHF at our center. Most patients with AHF, who fulfill the Kings College Criteria for LT, did not survive longer without LT. ALSS did not improve the prognosis of AHF patients, but may extend the waiting time for a donor. Currently, LT is still the most effective way to improve the prognosis

  13. Risk of Severe Acute Exacerbation of Chronic HBV Infection Cancer Patients Who Underwent Chemotherapy and Did Not Receive Anti-Viral Prophylaxis.

    Chih-An Shih

    Full Text Available Reactivation of HBV replication with an increase in serum HBV DNA and alanine aminotransferase (ALT activity has been reported in 20-50% of hepatitis B carriers undergoing cytotoxic chemotherapy for cancer treatment. Manifestation of HBV reactivation ranges from asymptomatic self-limiting hepatitis to severe progressive hepatic failure and fatal consequences.To investigate the risk of severe acute exacerbation of chronic HBV infection in HBsAg-positive cancer patients with solid tumors or hematological malignancies who underwent chemotherapy without antiviral prophylaxis.A retrospective review of charts was conducted for HBsAg-positive cancer patients in our institution who underwent chemotherapy and did not receive anti-viral prophylaxis between the periods of July 2007 to January 2013. We investigate the incidence of severe acute exacerbation of chronic HBV infection if these patients with a variety of solid tumors and hematological malignancies.A total of 156 patients (hematological malignancies: 16; solid tumors: 140 were included. The incidence of severe acute HBV exacerbation in the patients with hematological malignancy was higher than that in solid tumors (25.0% [4/16] vs 4.3% [6/140]; P = 0.005. Additionally, patients receiving rituximab-based chemotherapy had higher acute exacerbation rate than those with non-rituximab-based chemotherapy (40.0% vs 4.1%, P = 0.001. Among the patients with solid tumors, the incidences of severe acute exacerbation of chronic HBV in hepatocellular carcinoma, colorectal cancer, lung cancer, breast cancer, gynecological cancer, urological tract cancer, head/neck cancer and other solid malignancies were 2.3%, 4.0%, 7.1%, 9.0%, 16.7%, 6.7%, 0% and 0%, respectively.Severe acute exacerbation of chronic HBV infection may occur in HBsAg-positive patients with a variety of solid tumors who received chemotherapy without adequate anti-viral prophylaxis. Hematological malignancy and rituximab-based chemotherapy are

  14. Unilateral Adie's tonic pupil and viral hepatitis: Report of two cases

    Karadžić Jelena

    2015-01-01

    Full Text Available Introduction. Adie’s (tonic pupil is a neuro-ophthalmological disorder characterized by a tonically dilated pupil, which is unresponsive to light. It is caused by damage to postganglionic fibers of the parasympathetic innervation of the eye, usually by a viral or bacterial infection. Adie’s syndrome includes diminished deep tendon reflexes. Outline of Cases. We report data of a 59-year-old female with unequal pupil sizes. She complained of blurred vision and headache mainly while reading. She had a 35-year history of hepatitis B and liver cirrhosis. On exam, left pupil was mydriatic and there was no response to light and at slit lamp we saw segments of the sphincter constrict. We performed 0.125% pilocarpine test and there was a remarkable reduction of size in the left pupil. The second case is a 55-year-old female who was referred to the University Eye Clinic because of a headache and mydriatic left pupil. She had diabetes mellitus type 2, as well as hepatitis A virus 20 years earlier. On exam, the left pupil was mydriatic, with no response to light. Test with diluted pilocarpine was positive. Neurological examinations revealed no abnormality in either case so we excluded Adie’s syndrome. Conclusion. Adie’s tonic pupil is benign neuro-ophthalmological disorder of unknown etiology. Most patients commonly present no symptoms and anisocoria is noticed accidentally. Although the etiology is unknown, there are some conditions that cause tonic pupil. It may be a part of a syndrome in which tonic pupil is associated with absent deep tendon reflexes.

    AIM: To explore the expression and replication of hepatitis B virus (HBV) DNA in primary duck hepatocytes (PDHs).METHODS: Complete HBV genome was transfected into PDHs by electroporation (transfected group, 1.19×1012copies of linear HBV DNA/1×107 PDHs). After 1-5 d of transfection, HBsAg and HBeAg in the supernatant and lysate of PDHs were measured with the IMX System.Meanwhile, replicative intermediates of HBV DNA were analyzed by Southern blotting and Dot blotting. PDHs electroporated were used as control group.RESULTS: HBsAg in the hepatocyte lysates of transfected group was 15.24 (1 d), 14.55 (3 d) and 5.13 (5 d; P/N values, positive≥2.1) respectively. HBeAg was negative (<2.1). Both HBsAg and HBeAg were negative in the supernatant of transfected group. Dot blotting revealed that HBV DNA was strongly positive in the transfected group and negative in the control group. Southern blot analysis of intracellular total DNA indicated that there were relaxed circular (rc DNA), covalently closed circular (ccc DNA), and single-stranded (ss DNA) HBV DNA replicative intermediates in the transfected group, there was no integrated HBV DNA in the cellular genome. These parameters were negative in control group.CONCLUSION: Expression and replication of HBV genes can occur in hepatocytes from non-mammalian species.HBV replication has no critical species-specificity, and yet hepatic-specific regulating factors in hepatocytes may be essential for viral replication.

  16. Chicken pox infection (varicella zoster virus) and acute monoarthritis: evidence against a direct viral mechanism.

    1992-01-01

    A 9 year old boy developed acute monoarthritis of the left knee concurrent with the appearance of a varicella zoster virus (VZV) rash. Repeated VZV DNA hybridisation of the cells within the synovial fluid and synovial membrane failed to show any evidence of intracellular virus. Virus was isolated from synovial fluid 24 hours after the start of clinical infection but not later. These findings suggest that the mechanism of the arthritis is not due to viral replication inside the swollen joint.

    Full Text Available Purpose: Viral etiology is common in cases of children with acute diarrhea, and antibiotic therapy is usually not required. Therefore, it is important to determine the distribution of common viruses among children hospitalized with acute diarrhea. Methods: We included 186 children who suffered from acute diarrhea and were hospitalized at the Wonkwang University Hospital Pediatric ward from December 1, 2010 to June 30, 2011 in this study. Stool samples were collected and multiplex reverse transcriptase polymerase chain reaction (multiplex RT-PCR was used to simultaneously determine the viral etiology such as rotavirus, norovirus, astrovirus, or adenovirus.&lt;br&gt; Results: Causative viruses were detected in 72 of the 186 cases (38.7%. The mean age of the viruspositive cases was 1 year and 9 months (range, 1 month to 11 years. Rotavirus was detected in 50/186 (26.9%; norovirus, in 18/186 (9.7%; and astrovirus, in 3/186 cases (1.6%. Adenovirus was not detected in any of the cases. Proportions of norovirus genogroups I and II were 21.1% and 78.9%, respectively. Four of the 51 rotavirus-positive cases (7.8% had received rotavirus vaccination at least once. The mean duration of diarrhea was 2.8 days (range, 1 to 10 days and vomiting occurred in 39 of the 72 cases (54.2%.&lt;br&gt; Conclusion: Viral etiology was confirmed in about one-third of the children with acute diarrhea, and the most common viral agent was rotavirus, followed by norovirus.

    BACKGROUND: With the development of the associated technology, interventional treatment has become an important method for the treatment of hepatic artery occlusion in some countries. This study was undertaken to evaluate the role of interventional methods in the diagnosis and treatment of acute hepatic artery occlusion after liver transplantation. METHODS: The diagnosis and treatment of 9 cases of acute hepatic artery occlusion after liver transplantation were retrospectively analyzed. RESULTS: In 109 cases of liver transplantation, 9 were diagnosed by angiography. Among them, 7 were diagnosed by Doppler ultrasound. After transcatheter thrombolysis, the hepatic arteries were partially or totally patent again in 6 cases of hepatic artery occlusion after liver transplantation, and stent placements in the hepatic artery were performed in 5 cases. All stents proved patent and no patient required another liver transplantation. CONCLUSIONS: Angiography plays an important role in diagnosing hepatic artery complications after liver transplantation. Interventional therapy is a valuable method in the treatment of acute hepatic artery occlusion after liver transplantation.

    Myron J Tong; Lawrence M Blatt; Jia-Horng Kao; Jason Tzuying Cheng; William G Corey

    2006-01-01

    AIM: To conduct a retrospective study in 400 chronic hepatitis B patients in order to identify hepatitis B viral factors associated with complications of liver disease or development of hepatocellular carcinoma.METHODS: The mean follow-up time was 83.6 ± 39.6mo. Alpha-fetoprotein test and abdominal ultrasound were used for cancer surveillance. Hepatitis B basal core promoter mutants, precore mutants, genotypes,hepatitis B viral DNA (HBV DNA) level and hepatitis B e antigen (HBeAg) were measured. Univariate analysis and logistic regression were used to assess odds ratios for viral factors related to liver deaths and hepatocellular carcinoma development.RESULTS: During follow-up, 38 patients had liver deaths not related to hepatocellular carcinoma. On multivariate analysis, older age [odds ratio: 95.74 (12.13-891.31);P < 0.0001], male sex [odds ratio: 7.61 (2.20-47.95);P = 0.006], and higher log10 HBV DNA [odds ratio:4.69 (1.16-20.43); P < 0.0001] were independently predictive for these liver related deaths. Also, 31 patients developed hepatocellular carcinoma. Multivariate analysis showed that older age [odds ratio: 26.51 (2.36-381.47);P = 0.007], presence of precore mutants [odds ratio:4.23 (1.53-19.58); P = 0.02] and presence of basal core promoter mutants [odds ratio: 2.93 (1.24-7.57); P =0.02] were independent predictors for progression to hepatocellular carcinoma.CONCLUSION: Our results show that high levels of baseline serum HBV DNA are associated with nonhepatocellular carcinoma-related deaths of liver failure,while genetic mutations in the basal core promoter and precore regions are predictive for development of hepatocellular carcinoma.

  9. Some points of the X-ray pattern of acute viral primary pneumonia caused by acute respiratory disease viruses

    An analysis is made of the results of the X-ray studies as well as of the virological and serological tests in 225 out-patients consulted in the first days of their complaints. A predominance of the viral (70.2%) over the viral-bacterial primary pneumonia is established. The acute viral primary pneumonia are caused mostly by single influenza viruses and more rarely - by single respiratory viruses; in the cases of combined influenza viruses influenza-influenza viruses prevail over the influenza-respiratory ones. The morphological changes in pneumonia due to isolated single influenza viruses involve mostly the interstitium and are projected on X-ray as patchy and stripped densities. The inflamatory changes in pneumonia caused by combined influenza viruses affect both ihe interstitium and the broncho-alveolar substrate of the lungs; they are manifested in two roentgenologic forms: creeping (migrating) and fusing (confluent). In viral-bacterial pneumonia the changes affect mostly the lobe. The right lung and the lower parts of the both lungs are affected in most cases. 5 figs., 21 refs

    Hepatitis B e-antigen negative (e(-)) chronic HBV infection (CHI) encompasses a heterogeneous clinical spectrum ranging from inactive carrier (IC) state to e(-) chronic hepatitis B (CHB), cirrhosis and hepatic decompensation. In the backdrop of dysfunctional virus-specific T cells, natural killer (NK) cells are emerging as innate effectors in CHI. We characterized CD3(-) CD56(+) NK cells in clinically well-defined, treatment-naive e(-) patients in IC, e(-)CHB or decompensated liver cirrhosis (LC) phase to appraise their role in disease progression. The NK cell frequencies increased progressively with disease severity (IC 8.2%, e(-)CHB 13.2% and LC 14.4%). Higher proportion of NK cells from LC/e(-)CHB expressed CD69, NKp46, NKp44, TRAIL and perforin, the last two being prominent features of CD56(bright) and CD56(dim) NK subsets, respectively. The frequencies of CD3(-) CD56(+) NK cells together with TRAIL(+) CD56(bright) and Perforin(+) CD56(dim) NK cells correlated positively with serum alanine transaminase levels in e(-)CHB/LC. K562 cell-stimulated NK cells from e(-)CHB/LC exhibited significantly greater degranulation but diminished interferon-γ production than IC. Further, Perforin(+) NK cell frequency inversely correlated with autologous CD4(+) T-cell count in e(-) patients and ligands of NK receptors were over-expressed in CD4(+) T cells from e(-)CHB/LC relative to IC. Co-culture of sorted CD56(dim) NK cells and CD4(+) T cells from e(-)CHB showed enhanced CD4(+) T-cell apoptosis, which was reduced by perforin inhibitor, concanamycin A, suggesting a possible perforin-dependent NK cell-mediated CD4(+) T-cell depletion. Moreover, greater incidence of perforin-expressing NK cells and decline in CD4(+) T cells were noticed intrahepatically in e(-)CHB than IC. Collectively, NK cells contribute to the progression of e(-)CHI by enhanced TRAIL- and perforin-dependent cytolytic activity and by restraining anti-viral immunity through reduced interferon-γ secretion and

    We reported a case of non-Hodgkin's lymphoma where liver involvement was the predominant clinical manifestation. A 27-year old man presented wiht markedly elevated serum aspartate aminotrasferase, alanine aminotransferase and lactate dehydrogenase, reduced prothrombin activity, thrombocytopenic purpura and hepato-splenomegaly without adenopathy. Viral, toxic,autoimmune and metabolic liver diseases were excluded.Bone marrow biopsy showed an intracapillary infiltration of T-lymphocytes with no evidence of lipid storage disease.Because of a progressive spleen enlargement, splenectomy was performed. Histological examination showed lymphomatous intrasinuses invasion of the spleen.Immunohistochemical investigation revealed the T phenotype of the neoplastic cells: CD45+, CD45RO+,CD3+, CD4-, CD8-, TIA1-. About 50 % of the lymphoid cells expressed CD56 antigen. The diagnosis of hepatosplenic T cell lymphoma was done. The patient was treated with chemotherapy, which induced a complete remission. Eighteen months later, he had a first relapse with increased aspartate aminotransferase, alanine aminotransferase, lactate dehydrogenase,thrombocytopenic purpura and blast in the peripheral blood.In spite of autologous bone marrow transplantation, he died twenty months after the diagnosis. Even in the absence of a mass lesion or lymphoadenopathy, hepatosplenic Tcell lymphoma should be considered in the differential diagnosis of a patient whose clinical course is atypical for acute hepatic dysfunction.

    Two girls aged 4 and 3 years, respectively, experienced acute liver failure due to accidental ingestion of supratherapeutic doses of paracetamol (90 mg/kg/day or more). Recognition of chronic paracetamol intoxication as a cause of acute hepatic failure is often delayed. It is important to consider t

  13. Detection of entero viruses and hepatitis A in treated wastewater and Correlation between viral and bacterial contamination

    The main human viruses likely to contaminate waste water are Non-enveloped viruses able to resist in the environment, so essentially the viruses presenting an enteric cycle of multiplication. Many of these viruses, namely entero virus, hepatitis Avirus are excreted in the saddles of patients or of carriers and meet in waste water. To fight against the viral risk it is necessary to have a methodology allowing the control and the surveillance of virological and Hydric contamination. For the revealing of enteric virus, the reference technique remains the isolation on cellular culture. However, the disadvantage of this technique is the fact that it is difficult for certain viruses. Thus, the rise of molecular biology allowed the focusing of reliable and significant methods for detection of the enteric viruses in the environmental takings. The aim of this work was to detect hepatitis A virus and entero virus in waste water. A total of 20 samples were concentrated then precipitated by Polyethylene glycol 6000 according to the method of EPA. Extraction and purification of the viral ARN are made by the Kit QIAmp Viral RNA (Qiagen). The analysis of nucleic acids extracted by RT-PCR allowed to detect Entero virus with a 15 pour cent frequency (3/20) and 10 pour cent (2/20) for the hepatitis A virus.

    A soluble DNA carrier system consisting of an asialoglycoprotein covalently linked to poly-L-lysine was used to bind DNA and deliver hepatitis B virus (HBV) DNA constructs to asialoglycoprotein receptor-positive human hepatoma cells. 4 d after transfection with surface or core gene expression constructs, HBsAg and HBeAg in the media were measured to be 16 ng/ml and 32 U/ml per 10(7) cells, respectively. Antigen production was completely inhibited by the addition of an excess of asialoorosomucoid. On the other hand, asialoglycoprotein receptor-negative human hepatoma cells, SK-Hep1, did not produce any viral antigens under identical conditions after incubation with HBV DNA complexed to a conjugate composed of asialoorosomucoid and poly-L-lysine. Using a complete HBV genome construct, HBsAg and HBeAg levels reached 16 ng/ml and 16 U/ml per 10(7) cells, respectively. Northern blots revealed characteristic HBV RNA transcripts including 3.5-, 2.4-, and 2.1-kb fragments. Intracellular and extracellular HBV DNA sequences including relaxed circular, linear and single stranded forms were detected by Southern blot hybridization. Finally, 42-nm Dane particles purified from the spent cultures medium were visualized by electron microscopy. This study demonstrates that a targetable DNA carrier system can transfect HBV DNA in vitro resulting in the production of complete HBV virions. Images PMID:8383700

    Full Text Available Suosuo grape (Vitis vinifer L is traditionally used as a therapeutic agent for measles and hepatitis by the ethnic Uighurs. This work aimed to investigate the anti-HBV effect of total triterpene (VTT, total flavonoids (VTF and total polysaccharides (VTP from Suosuo grape, and their synergistic effects were also tested. The viral antigens of cellular secretion, HBsAg and HBeAg, were determined by enzyme linked immunosorbent assay (ELISA.The quantity of HBV-DNA released in the supernatant was assayed by real-time PCR. It was found that it effectively suppressed the secretion of HBsAg and HBeAg from HepG2.2.15 cells in a dose-dependent manner, as well as the HBV DNA. The results of orthogonal design experiment showed that the combination of VTT 20 μg/mL, VTF 50 μg/mL and VTP 50 μg/mL had the best optimistic inhibitory effects on HBeAg secretion.

    Highlights: Black-Right-Pointing-Pointer P20, precursor of the HBeAg, interacts with the cellular protein gC1qR. Black-Right-Pointing-Pointer HBeAg and P20 bind to T cell surface and inhibit mitogen-induced T cell division. Black-Right-Pointing-Pointer HBeAg and P20 inhibition of T cell proliferation is gC1qR and IL-1RAcP-independent. -- Abstract: The hepatitis B virus (HBV) Precore protein is processed through the secretory pathway directly as HBeAg or with the generation of an intermediate (P20). Precore gene has been shown to be implicated in viral persistence, but the functions of HBeAg and its precursors have not been fully elucidated. We show that the secreted proteins HBeAg and P20 interact with T cell surface and alter Kit-225 and primary T cells proliferation, a process which may facilitate the establishment of HBV persistence. Our data indicate that the N-terminal end of Precore is important for these inhibitory effects and exclude that they are dependent on the association of HBeAg and P20 with two characterized cell surface ligands, the Interleukin-1 Receptor Accessory Protein and gC1qR (present study).

  18. PDW Index - A Simple Model for the Prediction of Liver Fibrosis in Chronic Viral Hepatitis

    Objectives: To assess the accuracy of platelets, platelet morphological parameters, mean platelet volume(MPV) and platelet distribution width, (PDW) to diagnose advanced fibrosis. Study Design: Validation study. Place and Duration of Study: Combined Military Hospital, Malir, from Jun 2008 to Jun 2009. Patients and Methods: Simple laboratory tests, aspartate aminotransferase (AST) alanine aminotransferase (ALT) platelet count and platelet morphological parameters were measured in 91 chronic viral hepatitis patients. All patients had liver biopsy performed. A new index, PDW index was derived to detect the opposing effects of liver fibrosis on platelet count, MPV, and PDW. The predictive value of the index for advanced fibrosis (F3-F4) was assessed through descriptive statistics and area under the ROC curves. Results: Two cut-offs were chosen to qualify different stages of fibrosis. A value of > 8.00 predicted advanced fibrosis, F3-F4, with a specificity of 94% and positive predictive value of 78%. A value of < 6.00 ruled out advanced fibrosis with a negative predictive value of 93% and a sensitivity of 82%. The area under the ROC curve for advanced fibrosis was 0.840. PDW Index values outside of these cut-offs correctly classified 60% of patients. Conclusion: A simple index comprising platelet as only parameters have high diagnostic value for the advanced stages of fibrosis. (author)

    BACKGROUND:Viral hepatitis B accounts for over 80%of acute hepatic failures in China and the patients die mainly of its complications. A patient with hepatic failure and fever is not uncommon, whereas repeated fever is rare. METHODS:A 32-year-old female was diagnosed with subacute hepatic failure and hepatitis B viral infection because of hyperbilirubinemia, coagulopathy, hepatic encephalopathy, serum anti-HBs-positive without hepatitis B vaccination, and typical intrahepatic pathological features of chronic hepatitis B. Plasma exchange was administered twice and she awoke with hyperbilirubinemia and discontinuous fever. RESULTS:Urethritis was conifrmed and medication-induced fever and/or spontaneous bacterial peritonitis (Gram-negative bacillus infection) was suspected. The patient was treated with antibiotics, steroids and a Chinese herbal medicine, matrine, for three months and she recovered. CONCLUSION:The survival rate of patients with hepatic failure might be improved with comprehensive supporting measures and appropriate, timely management of com-plications.

    AIM To investigate the role of blood transfusion in TT viral infection (TTV).METHODS We retrospectively studied serum samples from 192 transfusion recipients who underwent cardiovascular surgery and blood transfusion between July 1991 and June 1992. All patients had a follow-up every other week for at least 6 months after transfusion. Eighty recipients recipents blood before screening donors for hepatitis C antibody (anti-HCV), and 112 recipients reveiver screened blood.Recipients with alanine aminotransferase level > 2.5 times the upper normal limit were tested for serological markers for viral hepatitis A, B,C, G, Epstein-Barr virus and cytomegalovirus.TTV infection was defined by the positivity for serum TTV DNA using the polymerase chain reaction method. RESULTS Eleven and three patients, who reveiver anti-HCV unscreened and screened blood, respectively, had serum ALT levels >90 IU/L. Five patients (HCV and TTV: 1; HCV,HGV, and TTV: 1; TTV: 2; and CMV and TTV: 1 )were positive for TTV DNA, and four of them had sero-conversion of TTV DNA. CONCLUSION TTV can be transmitted via blood transfusion. Two recipients infected by TTV alone may be associated with the hepatitis.However, whether TTV was the causal agent remains unsettled, and further studies are necessary to define the role of TTV infection in chronic hepatitis.

    Full Text Available Propiltiouracil é uma droga amplamente utilizada no tratamento do hipertiroidismo. A hepatotoxicidade é um dos efeitos colaterais mais raros e também mais graves associados a ela. Relata-se um caso de hepatite aguda colestática que acomete um jovem de 15 anos em uso de propiltiouracil para tratamento de hipertiroidismo. Causas virais, metabólicas e autoimunes foram excluídas e a biopsia hepática revelou achados histopatológicos sugestivos de hepatite colestática induzida por droga. Com a suspensão da droga, houve remissão dos sintomas e normalização progressiva das provas de função hepática. Raramente, os pacientes em uso de propiltiouracil podem desenvolver injúria hepática grave.Propylthiouracil is widely used to treat patients with hyperthyroidism. However, propylthiouracil-induced hepatitis is an uncommon entity. The case of a 15-year-old boy treated with propylthiouracil for hyperthyroidism who developed a cholestatic acute hepatitis is reported. Viral, metabolic and autoimmune liver diseases were excluded and liver biopsy showed a pattern suggestive of drug-induced cholestatic hepatitis. After discontinuating the drug, there was a progressive resolution of symptoms and normalization of liver biochemical tests. Despite its rarity, patients receiving propylthiouracil are exposed to develop severe hepatotoxicity.

    Whereas a significant role for intestinal microbiota in affecting the pathogenesis and progression of chronic hepatic diseases is well documented, the contribution of the intestinal flora to acute liver injury has not been extensively addressed. Elucidating the influence of the intestinal microbiota on acute liver inflammation would be important for better understanding the transition from acute injury to chronic liver disease. Using the Concanavalin A (ConA)-induced liver injury model in lab...

    AIM: To study the sequential changes of serum ferritin levels in lamivudine-treated patients with chronic viral hepatitis B and the clinical implications.METHODS: Thirty-eight patients with chronic viral hepatitis B were prospectively studied during their treatment with lamivudine. Each patient received 100 mg oral lamivudine daily for 12 mo, and was observed and tested for blood biochemistry and hepatitis B virus (HBV) DNA levels and serum ferritin levels at baseline and at 3, 6 and 12 mo during the treatment. Serum HBV DNA levels were quantitatively determined using fluorescent quantitative polymerase chain reaction (FQ-PCR), and serum ferritin levels were measured by radioimmunoassay. The sequential changes of serum ferritin levels and their relationships with virological, serological and biochemical responses in the patients were analyzed.RESULTS: All the patients had a baseline HBV DNA level higher than 1x107 copies/L as determined by FQ-PCR and positive HBsAg and HBeAg and abnormal ALT levels. At the end of the 12-mo treatment, 19 of the 38(50.00%) patients had undetectable serum HBV DNA levels by FQ-PCR, and 12(31.58%) became negative for serum HBeAg and 10(26.32%) had seroconversion from HBeAg to HBeAb. Nineteen out of the 38(50.00%) patients had biochemically normal ALT levels after 12-mo lamivudine treatment. Sequential determination showed that lamivudine treatment significantly reduced ferritin levels in chronic hepatitis B patients. When the patients were divided into different groups according to their posttreatment virological, serological and biochemical responses for analysis of the sequential changes of ferritin levels, it was found that the decrease of ferritin levels in HBV DNA-negative group was significantly more obvious than that in HBV DNApositive group at 6 mo during the treatment (P=0.013).Consecutive comparisons showed that ferritin levels at 3 mo of treatment were obviously decreased as compared with the baseline levels (P<0.05) in HBe

  6. Trends of acute hepatitis B notification rates in eastern China from 2005 to 2013.

    Zhifang Wang

    Full Text Available Zhejiang Province was a high endemicity for hepatitis B disease in the 1990's. A number of measures implemented since then have begun to control and prevent hepatitis B. In 1992, hepatitis B vaccine came on the market. In 2002, hepatitis B vaccine was included in the national Expanded Programme on Immunization (EPI. Between 2007 and 2010, catch-up vaccination was implemented for children under 15. Since 2010, vaccination guidelines for high-risk groups have also been adopted. This study evaluated the impact of these control and prevention strategies on acute hepatitis B notification rates from 2005 through 2013. Data from the National Notifiable Disease Reporting System (NNDRS revealed a steady downward trend in notification rates of acute hepatitis B. The most dramatic decline occurred among pre-adults, highlighting the benefits of EPI's policy of universal vaccination for children. However, the highest notification rates occurred among young adults of lower socio-economic status. These findings indicate the strong need to vaccinate young adults at risk for HBV infection as well as to collect risk-factor information in the NNDRS for monitoring and following up persons with acute hepatitis B.

  7. Acute mucosal pathogenesis of feline immunodeficiency virus is independent of viral dose in vaginally infected cats

    Full Text Available Abstract Background The mucosal pathogenesis of HIV has been shown to be an important feature of infection and disease progression. HIV-1 infection causes depletion of intestinal lamina propria CD4+ T cells (LPL, therefore, intestinal CD4+ T cell preservation may be a useful correlate of protection in evaluating vaccine candidates. Vaccine studies employing the cat/FIV and macaque/SIV models frequently use high doses of parenterally administered challenge virus to ensure high plasma viremia in control animals. However, it is unclear if loss of mucosal T cells would occur regardless of initial viral inoculum dose. The objective of this study was to determine the acute effect of viral dose on mucosal leukocytes and associated innate and adaptive immune responses. Results Cats were vaginally inoculated with a high, middle or low dose of cell-associated and cell-free FIV. PBMC, serum and plasma were assessed every two weeks with tissues assessed eight weeks following infection. We found that irrespective of mucosally administered viral dose, FIV infection was induced in all cats. However, viremia was present in only half of the cats, and viral dose was unrelated to the development of viremia. Importantly, regardless of viral dose, all cats experienced significant losses of intestinal CD4+ LPL and CD8+ intraepithelial lymphocytes (IEL. Innate immune responses by CD56+CD3- NK cells correlated with aviremia and apparent occult infection but did not protect mucosal T cells. CD4+ and CD8+ T cells in viremic cats were more likely to produce cytokines in response to Gag stimulation, whereas aviremic cats T cells tended to produce cytokines in response to Env stimulation. However, while cell-mediated immune responses in aviremic cats may have helped reduce viral replication, they could not be correlated to the levels of viremia. Robust production of anti-FIV antibodies was positively correlated with the magnitude of viremia. Conclusions Our results indicate

    Despite strong evidence suggestive of associations between hepatic diseases and pancreas injury, a potential relationship between acute hepatitis and acute pancreatitis has not been a matter of review; which we focused on in the current paper. Some of the main findings of this review article are: fulminant hepatitis failure represents the highest incident rate of hepatitis-related acute pancreatitis; so a screening program might be indicative in these patients. Specific characteristics of HAV-related pancreatitis are that it is a benign condition with no reported mortality; and a male preponderance in the incidence, with females developing in older ages and having shown the signs of both conditions simultaneously. The incidence of acute pancreatitis in HBV infection is the lowest, but the mortality was the highest. HEV-related acute pancreatitis was most likely to represent pseudocysts and there was an apparent ethnic-priority with Indian descents, the only reported cases in the literature. Hepatitis-related pancreatitis in liver transplant recipients was most frequent in HBV infected patients; and in IFN-induced pancreatitis, cessation of the drug was most effective in treatment, with no catastrophic event reported.

    Invariant NKT (iNKT) cells are involved in the pathogenesis of various infectious diseases. However, their role in hepatitis B virus (HBV) infection is not fully understood, especially in human species. In this study, 35 chronic hepatitis B (CHB) patients, 25 inactive carriers (IC) and 36 healthy controls (HC) were enrolled and the proportions of circulating iNKT cells in fresh isolated peripheral blood mononuclear cells (PBMC) were detected by flow cytometry. A longitudinal analysis was also conducted in 19 CHB patients who received antiviral therapy with telbivudine. Thereafter, the immune functions of iNKT cells were evaluated by cytokine secretion and a two-chamber technique. The median frequency of circulating iNKT cells in CHB patients (0.13%) was lower than that in HC (0.24%, P = 0.01) and IC (0.19%, P = 0.02), and increased significantly during antiviral therapy with telbivudine (P = 0.0176). The expressions of CC chemokine receptor 5 (CCR5) and CCR6 were dramatically higher on iNKT cells (82.83%±9.87%, 67.67%±16.83% respectively) than on conventional T cells (30.5%±5.65%, 14.02%±5.92%, both P<0.001) in CHB patients. Furthermore, iNKT cells could migrate toward the CC chemokine ligand 5. Patients with a high ratio (≥1.0) of CD4−/CD4+ iNKT cells at baseline had a higher rate (58.33%) of HBeAg seroconversion than those with a low ratio (<1.0, 0%, P = 0.0174). In conclusion, there is a low frequency of peripheral iNKT cells in CHB patients, which increases to normal levels with viral control. The ratio of CD4−/CD4+ iNKT cells at baseline may be a useful predictor for HBeAg seroconversion in CHB patients on telbivudine therapy. PMID:22194934

    AIM: To estimate the prognosis of patients with liver failure using a scoring model of severe viral hepatitis (SMSVH) and a model of end stage liver disease (MELD)to provide a scientific basis for clinical decision of treatment.METHODS: One hundred and twenty patients with liver failure due to severe viral hepatitis were investigated with SMSVH established. Patients with acute, subacute,and chronic liver failure were 40, 46 and 34, respectively.The follow-up time was 6 mo. The survival rates of patients with liver failure in 2 wk, 4 wk, 3 mo and 6 mo were estimated with Kaplan-Meier method. Comparison between SMSVH and MELD was made using ROC statistic analysis.RESULTS: The survival curves of group A (at low risk,SMSVH score ≤ 4) and group B (at high risk, SMSVH score ≥ 5) were significantly different (The 4-wk, 3-mo, 6-mo survival rates were 94.59%, 54.05%, 43.24% in group A,and 51.81%, 20.48%, 12.05% in group B, respectively,P < 0.001). The survival curves of group C (SMSVH scores unchanged or increased), group D (SMSVH scores decreased by 1) and group E (SMSVH scores decreased by 2 or more) were significantly different .The survival rates of groups C, D and E were 66.15%, 100%, 100% in 2-wk; 40.0%, 91.18%, 100% in 4-wk; 0%, 58.82%,80.95% in 3-mo and 0%, 38.24%, 61.90% in 6-mo,respectively, P < 0.001). The area under the ROC curve (AUC) of SMSVH scores at baseline and after 2 wk of therapy was significantly higher than that under the ROC curve of MELD scores (0.804 and 0.934 vs 0.689, P <0.001).CONCLUSION: SMSVH is superior to MELD in the estimation of the prognosis of patients with severe viral hepatitis within 6 mo. SMSVH may be regarded as a criterion for estimation of the efficacy of medical treatment and the decision of clinical treatment.

    Full Text Available Background: Treatment of hepatitis C virus (HCV infection with interferon (IFN and ribavirin (RBV is associated with adverse events, which may affect the patient's adherence to the treatment regimen and the treatment efficacy.Objectives: The aim of this study was to assess the sustained viral response (SVR and interdependence between the haematological characteristics (leukocyte count, platelet count, and haemoglobin levels in patients with chronic hepatitis C (CHC infection during treatment with IFN and RBV.Patients and Methods: We conducted a retrospective cohort study of 170 children with CHC infection who completed treatment with IFN-α and RBV. The children were divided into 2 groups: the first group (group I, n = 119 underwent a 48-week course of treatment with recombinant IFN α-2b (Intron A at a dosage of 3 MU 3 times a week subcutaneously and RBV at a dosage of 15 mg/kg per day orally, and the second group (group II, n = 51 was administered pegylated IFN (peg-IFN-α-2b (PegIntron at a dosage of 1.5 μg/kg per week subcutaneously and RBV at a dosage of 15 mg/kg per day orally for 48 weeks. The dose of IFN was not adjusted but that of ribavirin was in 2 children from group II. Hematological growth factors and erythropoietin were not used. SVR was defined as undetectable serum HCV RNA 24 weeks after the end of treatment (study week 72. Serum HCV RNA was determined by performing polymerase chain reaction, and the HCV genotypes and hematological parameters were evaluated. Serum HCV RNA levels were analysed by descriptive statistics.

    Although primary prevention of HAV and HBV can be achieved through vaccination, the burden of HCV can only be reduced through behavioral interventions to reduce its risk factors. This study evaluated knowledge regarding transmission, clinical manifestations and prevention of viral hepatitis in Puerto Rico. We assessed the level of knowledge about HAV (six questions), HBV (12 questions) and HCV (eight questions) among non-institutionalized Puerto Rican adults aged 21-64 years. Demographic characteristics and self-reported knowledge of these infections were determined through a face-to-face interview. A mean knowledge score was computed by summing correct responses to each scale. Mean knowledge scores according to demographics were compared using ANOVA or the Kruskal-Wallis test. Mean knowledge scores for HAV, HBV and HCV infections were 2.6 ± 1.5, 6.1 ± 2.4, and 3.6 ± 1.1, respectively. For HAV and HBV infections, the mean knowledge score significantly (P counseling received and number of sources of information. However, for HCV infection the mean knowledge score significantly increased with decreasing age, increased educational level and increased annual family income. Contrary to HBV, a higher HAV and HCV knowledge score was observed among individuals with history of vaccination for HAV and HBV, seropositive status for HAV and HCV, and history of drug use. A sizeable proportion of adults in this study demonstrated an inadequate level of knowledge, especially about transmission routes. Health education must be focused on transmission and prevention methods, including the availability of a vaccine for HAV and HBV, especially among those with chronic liver disease. PMID:21125319

    Hepatitis B virus (HBV) remains a major human pathogen despite the development of both antiviral drugs and a vaccine, in part because the current therapies do not suppress HBV replication far enough to eradicate the virus. Here, we screened 51 troponoid compounds for their ability to suppress HBV RNaseH activity and HBV replication based on the activities of α-hydroxytropolones against HIV RNaseH, with the goal of determining whether the tropolone pharmacophore may be a promising scaffold for anti-HBV drug development. Thirteen compounds inhibited HBV RNaseH, with the best 50% inhibitory concentration (IC50) being 2.3 μM. Similar inhibition patterns were observed against HBV genotype D and C RNaseHs, implying limited genotype specificity. Six of 10 compounds tested against HBV replication in culture suppressed replication via blocking of viral RNaseH activity, with the best 50% effective concentration (EC50) being 0.34 μM. Eighteen compounds inhibited recombinant human RNaseH1, and moderate cytotoxicity was observed for all compounds (50% cytotoxic concentration [CC50]=25 to 79 μM). Therapeutic indexes ranged from 3.8 to 94. Efficient inhibition required an intact α-hydroxytropolone moiety plus one or more short appendages on the tropolone ring, but a wide variety of constituents were permissible. These data indicate that troponoids and specifically α-hydroxytropolones are promising lead candidates for development as anti-HBV drugs, providing that toxicity can be minimized. Potential anti-RNaseH drugs are envisioned to be employed in combination with the existing nucleos(t)ide analogs to suppress HBV replication far enough to block genomic maintenance, with the goal of eradicating infection.

    Full Text Available Abstract Background The impact of hepatitis E in developed countries, like Italy, still requires a clear definition. In the present study, we evaluated HEV infection in patients with acute non-A-C hepatitis by an approach comparing data from Real-time PCR and serological assays. Methods In a first analysis, sera from 52 patients hospitalized with a diagnosis of acute viral non-A-C hepatitis in Italy were tested by in-house Real-Time PCR assay for identification of Hepatitis E Virus (HEV RNA and by anti-HEV IgM and IgG assays. In a subsequent analysis, selected samples were evaluated by additional IgM tests to confirm diagnosis. Results Among the 52 samples, 21 showed positive results for all three markers (IgM, IgG and HEV RNA. One patient showed HEV RNA as single marker. Uncertain results were found in 8 samples while the remaining 22 were negative for all markers. Further analysis of the 8 undefined samples by additional IgM tests confirmed HEV infection in 1 patient. Overall, acute HEV infections were reliably identified in 23 (44.2% out of 52 patients. Conclusions In the present paper, we performed a study evaluating HEV infection in 52 sporadic non-A-C acute hepatitis cases. All samples were collected from 2004 to 2010 in Italy. By a diagnostic strategy based on genomic and serological assays we identified HEV infections in 23 out of 52 patients (44.2%, a percentage higher than previous estimates. Thus, the actual impact of HEV infections in Italy needs to be further evaluated on a national scale by a diagnostic strategy based on multiple and last generation assays.

    1998-02-01

    Bovine viral diarrhea virus (BVDV) has been associated with several reproductive problems in cattle, including poor fertility, early embryonic deaths, abortion and congenital anomalies. Little is known about the cause of poor fertility in cows acutely infected with BVDV. The purpose of this study was to identify changes in ovarian function following acute infection with noncytopathic BVDV. The ovaries of 5 BVDV sero-negative and virus-negative pubertal heifers were monitored daily for 4 consecutive estrous cycles. The position and diameter of all follicles (> 5 mm) and luteal structures were recorded. Daily plasma samples were collected to measure peripheral progesterone and estradiol levels. Each heifer was infected intranasally with noncytopathic BVDV following ovulation of the second estrous cycle. The maximum diameter and growth rate of dominant anovulatory and ovulatory follicles were significantly reduced following acute BVDV infection. Similarly, the number of subordinate follicles associated with both the anovulatory and ovulatory follicle was reduced following infection. There were no significant differences in other follicle or luteal dynamic parameters or in peripheral progesterone or estradiol levels. Ovarian follicular growth was different during the first 2 estrous cycles following acute infection with BVDV when compared with the 2 estrous cycles preceding infection. These differences may be important in explaining reduced fertility in herds with acute BVDV infection. PMID:10732038

Pandemic H1N1 was the dominant influenza virus (IFV but was only detected in 20 (5.41% of children. Moreover, detection rate of RSV and human metapneumovirus (hMPV among suburb participants were significantly higher than that of urban area (P<0.05. Incidence of VSARI among suburb participants was also significant higher, especially among those of 24 to 59 months group (P<0.05. CONCLUSION: Piconaviruses (EV/RV and paramyxoviruses are the most popular viral pathogens among children with SARI in this study. RSV and hMPV significantly increase the risk of SARI, especially in children younger than 24 months. Higher incidence of VSARI and more susceptibilities to RSV and hMPV infections were found in suburban patients.

    ZHANG Xi-ping; WANG Lei; ZHANG Jie

    2007-01-01

    Study on the action mechanism of inflammatory mediators generated by the severe acute pancreatitis (SAP) in multiple organ injury is a hotspot in the surgical field. In clinical practice, the main complicated organ dysfunctions are shock, respiratory failure, renal failure, encephalopathy, with the rate of hepatic diseases being closely next to them. The hepatic injury caused by SAP cannot only aggravate the state of pancreatitis, but also develop into hepatic failure and cause patient death. Its complicated pathogenic mechanism is an obstacle in clinical treatment. Among many pathogenic factors, the changes ofvasoactive substances, participation of inflammatory mediators as well as OFR (oxygen free radical), endotoxin, etc. may play important roles in its progression.

    The Affordable Care Act presents financial challenges and opportunities for publicly funded service providers. We assessed billing practices and anticipated barriers to third-party billing among organizations in Texas that provide publicly funded HIV, sexually transmitted diseases, tuberculosis, and viral hepatitis services. One third to one half of the organizations did not bill for medical services. The most common barrier to third-party billing was lack of staff knowledge about billing and coding. Future research must evaluate options for organizations and communities to maintain access to infectious disease services for vulnerable populations. PMID:26447911

    2015-07-15

    Lateral flow assay (LFA) is an attractive method for rapid, simple, and cost-effective point of care diagnosis. For LFA-based multiplex diagnosis of three viral intractable diseases (acquired immune deficiency syndrome and hepatitis C and A), here we developed proteinticle-based 7 different 3D probes that display different viral antigens on their surface, which were synthesized in Escherichia coli by self-assembly of human ferritin heavy chain that was already engineered by genetically linking viral antigens to its C-terminus. Each of the three test lines on LFA strip contains the proteinticle probes to detect disease-specific anti-viral antibodies. Compared to peptide probes, the proteinticle probes were evidently more sensitive, and the proteinticle probe-based LFA successfully diagnosed all the 20 patient sera per each disease without a false negative signal, whereas the diagnostic sensitivities in the peptide probe-based LFAs were 65-90%. Duplex and triplex assays performed with randomly mixed patient sera gave only true positive signals for all the 20 serum mixtures without any false positive signals, indicating 100% sensitivity and 100% specificity. It seems that on the proteinticle surface the antigenic peptides have homogeneous orientation and conformation without inter-peptide clustering and hence lead to the enhanced diagnostic performance with solving the problems of traditional diagnostic probes. Although the multiplex diagnosis of three viral diseases above was demonstrated as proof-of-concept here, the proposed LFA system can be applied to multiplex point of care diagnosis of other intractable diseases.

  13. Development of a novel hepatitis B virus encapsidation detection assay by viral nucleocapsid-captured quantitative RT-PCR.

    Ryu, Dong-Kyun; Ahn, Yeji; Ryu, Wang-Shick; Windisch, Marc P

    2015-11-01

    After encapsidation, where pregenomic RNA (pgRNA) is packaged into viral nucleocapsids, hepatitis B virus (HBV) uses the pgRNA as a template to replicate its DNA genome by reverse transcription. To date, there are only two encapsidation detection methods for evaluating the amount of pgRNA packaged into nucleocapsids: (i) the RNase protection assay and (ii) the native agarose gel electrophoresis assay. However, these methods are complex and laborious because they require multiple pgRNA purification steps followed by detection via an isotope-labeled probe. Moreover, both assays are unsuitable for evaluating a large number of antiviral agents in a dose-dependent manner. To overcome these limitations, we devised a novel HBV encapsidation assay in a 96-well plate format using nucleocapsid capture plates coated with an anti-HBV core (HBc) antibody, usually employed in enzyme-linked immunosorbent assays, to immobilize viral nucleocapsids. Viral pgRNA is then detected by quantitative RT-PCR (RT-qPCR). This strategy allows fast, convenient, and quantitative analysis of multiple viral RNA samples to evaluate encapsidation inhibitors. Furthermore, our protocol is potentially suitable for high-throughput screening (HTS) of compounds targeting HBV pgRNA encapsidation. PMID:26554506

  15. Acute hepatitis in three patients with systemic juvenile idiopathic arthritis taking interleukin-1 receptor antagonist

    Hollister J Roger

    2009-12-01

    Full Text Available Abstract Purpose We investigated the etiology of acute hepatitis in three children with systemic Juvenile Idiopathic Arthritis (sJIA taking Interleukin-1 receptor antagonist (IL1RA. Methods Laboratory and clinical data for three children with sJIA diagnosed at ages 13 months to 8 years who developed acute hepatitis during treatment with IL1RA were reviewed for evidence of sJIA flare, infection, macrophage activation syndrome (MAS, malignancy, and drug reaction. Results In all patients, hepatitis persisted despite cessation of known hepatotoxic drugs and in absence of known infectious triggers, until discontinuation of IL1RA. Liver biopsies had mixed inflammatory infiltrates with associated hepatocellular injury suggestive of an exogenous trigger. At the time of hepatitis, laboratory data and liver biopsies were not characteristic of MAS. In two patients, transaminitis resolved within one week of discontinuing IL1RA, the third improved dramatically in one month. Conclusions Although sJIA symptoms improved significantly on IL1RA, it appeared that IL1RA contributed to the development of acute hepatitis. Hepatitis possibly occurred as a result of an altered immune response to a typical childhood infection while on IL1RA. Alternatively, hepatitis could have represented an atypical presentation of MAS in patients with sJIA taking IL1RA. Further investigation is warranted to determine how anti-IL1 therapies alter immune responsiveness to exogenous triggers in patients with immune dysfunction such as sJIA. Our patients suggest that close monitoring for hepatic and other toxicities is indicated when treating with IL1RA.

    Following injury, a large number of hepatic acute phase genes are rapidly modulated at the transcriptional level to restore metabolic homeostasis an limit tissue damage. Hepatocyte nuclear factor 4α (HNF-4α) is a liver-enriched transcription factor that controls embryonic liver development and regulates tissue specific gene expression in adult liver cells. Many genes encoding acute phase proteins contain HNF-4α binding sites in their promoter regions and are transcriptionally regulated by HNF...

  19. End-of-Treatment-Response in Patients Treated for Hepatitis C Virus with Standard Interferon and Ribavirin Based on Viral Load

    Objective: To determine the End-of-Treatment-Response (ETR) to standard interferon and ribavirin based regimen in patients of chronic hepatitis C and to compare the ETR response in low and high viral load groups. Study Design: Descriptive study. Place and Duration of Study: Virology Department, Armed Forces Institute of Pathology (AFIP), Rawalpindi, from March 2012 to May 2013. Methodology: Patients with chronic hepatitis C virus infection were included in the study. Pre-treatment viral load was determined by RoboGene Quantification kit. Based on viral load, the 400 patients were divided into two equal groups of low viral load (< 800,000 IU/ml) and high viral load (> 800,000 IU/ml). The patients were treated with standard interferon alpha (3 million units subcutaneously thrice weekly) and ribavirin (10.6 mg/kg body weight) for 6 months. ETR was measured using Sacace Biotechnologies Qualitative kit. Chi-square test was used to compare the ETR in the two viral load groups. P-value < 0.05 was considered as significant. Results: Out of 400 patients, 206 (51.5%) were males and 194 (48.5%) were females. Two hundred seventy (67.5%) patients achieved ETR and 130 (35.5%) failed to do so. In low viral load group, 145 (72.5%) patients achieved and 55 (27.5%) patients did not achieve ETR. In high viral load group, 123 (61.5%) patients achieved and 77 (38.5%) did not achieve ETR. The difference in ETR between low and high viral load groups was statistically significant (p=0.019). Conclusion: End-of-treatment-response in patients treated for hepatitis C virus with standard interferon and ribavirin was greater in patients with low viral load as compared to patients with high viral load.

    Hepatitis E virus is recently recognised as an important cause of non-A, non-B hepatitis. A total of 569 serum samples were screened for HEV between April 1997 and March 2000, by a commercially available HEV IgM capture ELISA. The diagnosis was invariably acute viral hepatitis for differential diagnosis of jaundice. The percentage of seropositivity was found to be 18.8% in confirmed Hepatitis E cases.

  1. Severe Aplastic Anemia following Acute Hepatitis from Toxic Liver Injury: Literature Review and Case Report of a Successful Outcome

    Kamran Qureshi

    2014-01-01

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

  2. Extracorporal hemodialysis with acute or decompensated chronical hepatic failure

    Wasem, Jürgen

    2006-04-01

    Full Text Available Background: Conventional diagnostic procedures and therapy of acute liver failure (ALF and acute-on-chronic liver failure (ACLF focus on to identify triggering events of the acute deterioration of the liver function and to avoid them. Further objectives are to prevent the development respectively the progression of secondary organ dysfunctions or organ failure. Most of the times the endocrinological function of the liver can to a wide extent be compensated, but the removal of toxins can only marginally be substituted by conventional conservative therapy. To improve this component of the liver function is the main objective of extracorporal liver support systems. The following principles of liver support systems can be differentiated: Artificial systems, bioartifical systems and extracorporal liver perfusion systems. This HTA report focuses on artificial systems (e.g. BioLogic-DT/-DTPF, MARS, Prometheus, because only these approaches currently are relevant in the German health care system. In 2004 a category "Extracorporal liver assist device" was introduced in the list of "additional payments" in the German DRG-system, which makes reimbursement for hospitals using the technology in inpatient care possible, based on an hospital's individual contract with statutory sickness funds. Objectives: To report the present evidence and future research need on medical efficacy and economic effectiveness of extracorporal liver support devices for treatment of patients with ALF or ACLF based on published literature data. Are artificial liver support systems efficient and effective in the treatment of ALF or ACLF? Methods: An extensive, systematic literature search in medical, economic, and HTA literature data bases was performed. Relevant data were extracted and synthesised. Results: Relevant controlled trials were detected for BioLogic-DT and MARS. No randomised controlled trial on Prometheus was found. None of the included studies on BioLogic-DT showed

  3. Treatment of chronic viral hepatitis with nitazoxanide and second generation thiazolides

    Emmet B Keeffe; Jean-Francois Rossignol

    2009-01-01

    Nitazoxanide, the first thiazolide, was originally developed for the treatment of Cryptosporidium parvum. More recently, antiviral activity of nitazoxanide against hepatitis B virus (HBV) and hepatitis C virus was recognized in in vitro systems. These basic studies led to phase Ⅱ clinical trials that demonstrated the safety and efficacy of nitazoxanide in combination with peginterferon, with or without ribavirin, in the treatment of chronic hepatitis C genotype 4. The sustained virologic response rate was 79% and 80% in two studies, which was higher than the response rate of 50% with the standard of care with peginterferon plus ribavirin. In very preliminary studies of patients with chronic hepatitis B, nitazoxanide suppressed serum HBV DNA and led to loss of hepatitis B e antigen in the majority of patients and hepatitis B surface antigen in approximately a quarter of patients. Randomized controlled studies of naive and nonresponder patients with chronic hepatitis C genotype 1 are underway, new second generation and controlled release thiazolides are being developed, and future studies of patients with chronic hepatitis B are planned.

    Full Text Available Abstract Background Many people now seek alternative methods of weight loss. The internet provides a readily available source of weight reduction products, the ingredients of which are often unclear. The authors describe a case of acute hepatitis in a 20 year old woman caused by such a product purchased over the internet. Case Presentation A 20-year old woman presented with a two day history of abdominal pain, vomiting and jaundice. There were no identifiable risk factors for chronic liver disease. Liver function tests demonstrated an acute hepatitis (aminoaspartate transaminase 1230 IU/L. A chronic liver disease screen was negative. The patient had started a weight loss product (Pro-Lean, purchased over the internet two weeks prior to presentation. The patient was treated conservatively, and improved. The sequence of events suggests an acute hepatitis caused by an herbal weight loss product. Conclusion This case report highlights the dangers of weight loss products available to the public over the internet, and the importance of asking specifically about alternative medicines in patients who present with an acute hepatitis.

  10. Diagnosing viral and bacterial respiratory infections in acute COPD exacerbations by an electronic nose: a pilot study.

    van Geffen, Wouter H; Bruins, Marcel; Kerstjens, Huib A M

    2016-01-01

    Respiratory infections, viral or bacterial, are a common cause of acute exacerbations of chronic obstructive pulmonary disease (AECOPD). A rapid, point-of-care, and easy-to-use tool distinguishing viral and bacterial from other causes would be valuable in routine clinical care. An electronic nose (e-nose) could fit this profile but has never been tested in this setting before. In a single-center registered trial (NTR 4601) patients admitted with AECOPD were tested with the Aeonose(®) electronic nose, and a diagnosis of viral or bacterial infection was obtained by bacterial culture on sputa and viral PCR on nose swabs. A neural network with leave-10%-out cross-validation was used to assess the e-nose data. Forty three patients were included. In the bacterial infection model, 22 positive cases were tested versus the negatives; and similarly 18 positive cases were tested in the viral infection model. The Aeonose was able to distinguish between COPD-subjects suffering from a viral infection and COPD patients without infection, showing an area under the curve (AUC) of 0.74. Similarly, for bacterial infections, an AUC of 0.72 was obtained. The Aeonose e-nose yields promising results in 'smelling' the presence or absence of a viral or bacterial respiratory infection during an acute exacerbation of COPD. Validation of these results using a new and large cohort is required before introduction into clinical practice. PMID:27310311

    2008-01-01

    AIM: To study the virological and host factors influencing hepatitis C infection outcomes in heroin users in southern China.METHODS: HCV RNA and associated factors were analyzed among 347 heroin users from Guangxi Zhuang Autonomous Region, southern China who were hepatitis C virus (HCV) EIA positive for two or more consecutive visits.RESULTS: Using the COBAS AMPLICOR HCV TEST, a remarkably low HCV RNA negative rate of 8.6% was detected. After multivariate logistic regression analysis, HCV RNA clearance was significantly associated with the presence of HBsAg (OR = 8.436, P < 0.0001), the lack of HIV-1 infection (OR = 0.256, P = 0.038) and age younger than 25 (OR = 0.400, P = 0.029).CONCLUSION: Our study suggests HCV infection among Chinese heroin users results in high levels of viral persistence even amidst factors previously found to enhance viral clearance. Prospective studies of a possible genetic component within the Chinese population and the pathogenicity of non-genotype 1 HCV infections are needed.

    The prevalence of different genotypes of hepatitis C virus (HCV) in Ethiopia is not known. HCV genotypes influence the response to therapy with alpha-interferon alone or in combination with ribavirin. A cross sectional study was conducted on attendees of voluntary counseling and testing center. Serum samples from 1,954 (734 HIV positive and 1,220 HIV negative) individuals were screened for HCV antibody. Active HCV infection was confirmed by quantitative PCR in 18 of the 71 samples with anti-HCV antibodies. The HCV viral load ranged from 39,650 to 9,878,341 IU/ml (median 1,589,631 IU/ml) with no significant difference [χ(2)(17) = 18.00, P = 0.389] between persons positive or negative for HIV. The viral load of HCV was, however, higher in older study subjects (r = 0.80, P = 0.000). HCV genotypes were determined using the VERSANT HCV Genotype Assay (LiPA) and sequence analysis of the NS5b region of the HCV genome. Diverse HCV genotypes were found including genotypes 1, 2, 4, and 5. There was no difference in the distribution regarding the HIV status. As in other parts of the world, genotyping of HCV must be considered whenever HCV is incriminated as a cause of hepatitis. PMID:21351106

  13. Antiviral Activity of Marine Actinobacteria against Bovine Viral Diarrhea Virus, a Surrogate Model of the Hepatitis C Virus

    2015-12-01

    Full Text Available The Hepatitis C virus (Flaviviridae family, Hepacivirus genus represents a major public health problem worldwide and it is responsible for chronic infections in humans, which can develop to liver cirrhosis and hepatocellular carcinoma. As this virus does not replicate efficiently in cell culture and in animals, bovine viral diarrhea virus (BVDV is used as a surrogate model for screening assays of antiviral activity, and mechanism of action assays. From marine invertebrates and their microorganisms isolated, we prepared extracts and fractions, and we isolated substances for assessment of their possible antiviral activity. Of the 71 tested, seven were considered promising presenting protection percentage of more than 80%. The best inhibition results were obtained from the extracts produced by the Gordonia bacteria samples with 99.9% inhibition and by Micrococcus with 99% inhibition. Furthermore, most of the extracts selected by the protection percentage showed selectivity index values considered promising, especially the extracts of the bacteria Williansia (SI=27 and Brachybacterium (SI=39. On the action mechanism, most of the promising extracts showed activity in the inhibition of intracellular replication steps, although it has been observed action of different extracts in several stages of viral replicative cycle. Thus, various extracts stood out and may lead to the development of drugs that ensure an alternative therapy for the treatment of hepatitis C.

    Objective: To evaluate the clinical efficacy of Shengmai Powder (SMP, 生脉散) in treating acute viral myocarditis objectively. Methods: One hundred and twenty-four patients with acute viral myocarditis were randomized into the treated group (SMG, n=64) and the control group(CG, n=60 ). Such myocardial nutrient medicine as ATP, CoA, Vit-C, were given to both groups. And to the treated group, 40 ml of Shengmai Injection per day was given intravenously for 2 weeks, which was followed by oral intake of Shengmai granule, one package three times daily for another 2 weeks in total. The same anti-arrhythmia agents were applied to both groups, and no fructose-1, 6-diphosphate (FDP) for either. Semi-quantitative scoring method was adopted to observe such symptoms as chest stuffiness, palpitation and chest pain before treatment and four weeks after treatment. Meanwhile, ECG, dynamic ECG by Holter monitor, left ventricular enddiastolic dimension (LVEDD), left ventricular ejection fraction (LVEF), serum neutralizing antibody of virus Coxsackie B, cardiac troponin I (cTnl) and cardiac troponin T (cTnT) were examined. Results: (1) Compared with the control group, more significant improvement was got in SMG in respects of chest stuffiness, palpitation, chest pain and arrhythmia ( P<0.05 or P<0.01). (2) Negative converting rates of cTnl , cTnT in the two groups were 59.46% vs 35.48%, 68.75% vs 42.31% respectively (P<0.05). (3) LVEDD before and after treatment in SMG was 52.44±3.40 mm and 48.81± 2.23mm respectively, while that in the control group was 52.31±3.74 mm and 49.92±2.67mm respectively; LVEF before and after treatment in SMG was 60.67±4.62 % and 65.02±4.16 % respectively, while that in the control group was 60.91± 4.26 % and 63.67±3.17 %. There was obvious improvement in the two parameters in both groups, but the improvement in SMG was superior to that in the control group (P<0.05). Conclusion: SMP shows a good effect in improving clinical symptoms and

    Treatment of hepatitis C patients with direct-acting antiviral drugs involves the combination of multiple small-molecule inhibitors of distinctive mechanisms of action. ACH-806 (or GS-9132) is a novel, small-molecule inhibitor specific for hepatitis C virus (HCV). It inhibits viral RNA replication in HCV replicon cells and was active in genotype 1 HCV-infected patients in a proof-of-concept clinical trial (1). Here, we describe a potential mechanism of action (MoA) wherein ACH-806 alters viral replication complex (RC) composition and function. We found that ACH-806 did not affect HCV polyprotein translation and processing, the early events of the formation of HCV RC. Instead, ACH-806 triggered the formation of a homodimeric form of NS4A with a size of 14 kDa (p14) both in replicon cells and in Huh-7 cells where NS4A was expressed alone. p14 production was negatively regulated by NS3, and its appearance in turn was associated with reductions in NS3 and, especially, NS4A content in RCs due to their accelerated degradation. A previously described resistance substitution near the N terminus of NS3, where NS3 interacts with NS4A, attenuated the reduction of NS3 and NS4A conferred by ACH-806 treatment. Taken together, we show that the compositional changes in viral RCs are associated with the antiviral activity of ACH-806. Small molecules, including ACH-806, with this novel MoA hold promise for further development and provide unique tools for clarifying the functions of NS4A in HCV replication. PMID:23629709

    Hepatic steatosis (HS) can exacerbate acute pancreatitis (AP). This study aimed to investigate the relation between α1-antitrypsin (AAT) and acute pancreatitis when patients have HS. Using proteomic profiling, we identified 18 differently expressed proteins pots in the serum of rats with or without HS after surgical establishment of AP. AAT was found to be one of the significantly down-regulated proteins. AAT levels were significantly lower in hepatic steatosis acute pancreatitis (HSAP) than in non-HSAP (NHSAP) (P AAT in the serum of 240 patients with HSAP, NHSAP, fatty liver disease (FLD), or no disease. Compared with healthy controls, serum AAT levels in patients with NHSAP were significantly higher (P AAT levels were significantly lower (P AAT levels (r = -0.85, P AAT in patients with HSAP are correlated with disease severity and AAT may represent a potential target for therapies aiming to improve pancreatitis.

  19. Acute paranoid psychosis as sole clinical presentation of hepatic artery thrombosis after living donor liver transplantation

    Obed Aiman

    2010-02-01

    Full Text Available Abstract Background Hepatic artery thrombosis is a devastating complication after orthotopic liver transplantation often requiring revascularization or re-transplantation. It is associated with considerably increased morbidity and mortality. Acute cognitive dysfunction such as delirium or acute psychosis may occur after major surgery and may be associated with the advent of surgical complications. Case presentation Here we describe a case of hepatic artery thrombosis after living-donor liver transplantation which was not preceded by signs of liver failure but rather by an episode of acute psychosis. After re-transplantation the patient recovered without sequelae. Conclusion This case highlights the need to remain cautious when psychiatric disorders occur in patients after liver transplantation. The diagnostic procedures should not be restricted to medical or neurological causes of psychosis alone but should also focus vascular complications related to orthotopic liver transplantation.

  20. Value of computed tomography and magnetic resonance imaging for assessing severity of liver cirrhosis secondary to viral hepatitis

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

    The liver biopsy has long been the "gold standard" for assessing liver fibrosis in patients with hepatitis C. It's an invasive procedure which is associated with an elevated bleeding, especially in chronic hemodialysis patients. Main goal is to assess liver fibrosis in chronic hemodialysis with HCV by Fibroscan and by biological scores (APRI, Forns and Fib-4), and to measure the correlation between these tests. Cross-sectional study including all chronic hemodialysis patients with hepatitis C...

  8. Role of organic phosphorous in diagnosis of viral hepatitis patients B and C

    Biochemical and radiochemical analysis were performed on blood of egyptian men infected with hepatitis B, C and mixed B and C viruses as well as normal controls. The results revealed remarkable significant and very highly significant increases in ALT and AST activities in all patient groups. Regarding ALP enzyme, it showed significant increases in hepatitis C (Gr.III) and mixed hepatitis B and C (Gr. IV), whereas it showed a highly significant decrease in hepatitis B virus (Gr.II). GGT activity was highly significantly increased in Gr.II and Gr.III while non-significant change in Gr.IV was detected. Some biochemical compounds in blood especially phosphorus might taken as an early diagnostic tool for hepatitis phosphorus might taken as an early diagnostic tool for hepatitis B and C viruses. Inorganic phosphorus showed very high significant decreases in Gr.III and Gr.IV and a significant decrease in Gr.II. In respect with organic phosphorus, there were very high significant decrease in Gr.III, significant decrease in Gr.II and high significant decrease in Gr.IV

  9. Acute Herpes Simplex Viral Esophagitis Occurring in 5 Immunocompetent Individuals With Eosinophilic Esophagitis

    Criblez, Dominique H.; Dellon, Evan S.; Bussmann, Christian; Pfeifer, David; Froh, Matthias; Straumann, Alex

    2016-01-01

    Herpes simplex esophagitis (HSE) is an acute, severe viral infection of the esophagus, rarely occurring in immunocompetent individuals. Eosinophilic esophagitis (EoE) is a rare immune-mediated esophageal disorder. We recently observed 5 severe HSE cases in diagnosed EoE patients. Four of the 5 patients had active, untreated EoE at the time of infection, so HSE is not likely a side effect of swallowed topical corticosteroids, the first-line medical treatment of EoE. However, this coincidence of these 2 rare conditions raises the question of a causal relationship between these 2 forms of esophagitis, and whether active EoE might predispose to HSE infection.

  10. Acute fulminant subacute sclerosing panencephalitis in two patients: Dual viral hit hypothesis

    Rajesh Verma

    2012-01-01

    Full Text Available Subacute sclerosing panencephalitis (SSPE is a rare lethal neurological disorder caused by persistent mutant measles virus (MV in central nervous system. Usually affected individuals have a positive history of measles infection in infancy phase. The disease is characterized by progressive cognitive decline, deterioration in motor functions, repeated myoclonus finally leading to vegetative state and death. Commonly, SSPE patients manifest clinically after 2-10 years of intervening gap from primary measles infection. In last few years, atypical presentations of subacute sclerosing panencephalitis have been reported, many patients initially presenting with vision loss. Why only some patients developed SSPE after long gap of primary measles infection? Various immunological mechanisms have been hypothesized. It has been proven that subacute sclerosing panencephalitis patients failed to form adequate antibodies to measles virus M (matrix protein despite an appropriate response to other viral proteins. In this case report, we hypothesized that viral co-infections could lead to immune abnormalities and immunosuppression resulting into acute fulminant subacute sclerosing panencephalitis. We presented two patients of subacute sclerosing panencephalitis, one patient preceded by dengue virus infection and other by varicella zoster infection.

    2015-10-01

    Full Text Available ABSTRACT OBJECTIVE: Describe the clinical and laboratory profile, follow-up, and outcome of a series of cases of acute viral myositis. METHOD: A retrospective analysis of suspected cases under observation in the emergency department was performed, including outpatient follow-up with the recording of respiratory infection and musculoskeletal symptoms, measurement of muscle enzymes, creatine phosphokinase (CPK, lactate dehydrogenase (LDH, transaminases (AST and ALT, blood count, C-reactive protein, and erythrocyte sedimentation rate in the acute phase and during follow-up until normalization. RESULTS: Between 2000 and 2009, 42 suspected cases were identified and 35 (27 boys were included. The median age was 7 years and the diagnosis was reported in 89% in the first emergency visit. The observed respiratory symptoms were cough (31%, rhinorrhea (23%, and fever (63%, with a mean duration of 4.3 days. Musculoskeletal symptoms were localized pain in the calves (80%, limited ambulation (57%, gait abnormality (40%, and muscle weakness in the lower limbs (71%, with a mean duration of 3.6 days. There was significant increase in CPK enzymes (5507 ± 9180 U/L, LDH (827 ± 598 U/L, and AST (199 ± 245 U/L, with a tendency to leukopenia (4590 ± 1420 leukocytes/mm3. The complete recovery of laboratory parameters was observed in 30 days (median, and laboratory and clinical recurrence was documented in one case after 10 months. CONCLUSION: Typical symptoms with increased muscle enzymes after diagnosis of influenza and self-limited course of the disease were the clues to the diagnosis. The increase in muscle enzymes indicate transient myotropic activity related to seasonal influenza, which should be considered, regardless of the viral identification, possibly associated with influenza virus or other respiratory viruses.

  13. Noninvasive assessment of hepatic fibrosis in patients with chronic hepatic B viral Infection using magnetic resonance elastography

    To evaluate the diagnostic performance of magnetic resonance elastography (MRE) for staging hepatic fibrosis in patients with chronic hepatitis B virus (HBV) infection. Patients with chronic HBV infection who were suspected of having focal or diffuse liver diseases (n = 195) and living donor candidates (n = 166) underwent MRE as part of the routine liver MRI examination. We measured liver stiffness (LS) values on quantitative shear stiffness maps. The technical success rate of MRE was then determined. Liver cell necroinflammatory activity and fibrosis were assessed using histopathologic examinations as the reference. Areas under the receiver operating characteristic curve (Az) were calculated in order to predict the liver fibrosis stage. The technical success rate of MRE was 92.5% (334/361). The causes of technical failure were poor wave propagation (n = 12), severe respiratory motion (n = 3), or the presence of iron deposits in the liver (n = 12). The mean LS values, as measured by MRE, increased significantly along with an increase in the fibrosis stage (r = 0.901, p < 0.001); however, the mean LS values did not increase significantly along with the degree of necroinflammatory activity. The cutoff values of LS for ≥ F1, ≥ F2, ≥ F3, and F4 were 2.45 kPa, 2.69 kPa, 3.0 kPa, and 3.94 kPa, respectively, and with Az values of 0.987-0.988. MRE has a high technical success rate and excellent diagnostic accuracy for staging hepatic fibrosis in patients with chronic HBV infection.

  15. Euforia-induced acute hepatitis in a patient with scleroderma.

    Jiménez-Encarnación, Esther; Ríos, Grissel; Muñoz-Mirabal, Angel; Vilá, Luis M

    2012-01-01

    Euforia, a supplement containing a variety of natural ingredients, is widely used as an antioxidant and anti-inflammatory formula. It is not approved by the US Food and Drug Administration and its side effects are unknown. We report a 45-year-old woman with limited systemic sclerosis who presented with jaundice and marked elevation of serum transaminases. One month before, she started taking Euforia juice. A liver biopsy disclosed submassive hepatocellular necrosis with histopathological changes consistent with toxic hepatitis. The patient's symptoms resolved with cessation of Euforia. Six months later, she persisted with abnormal liver function tests, but these resolved 18 months after discontinuation of Euforia. The mechanism by which Euforia causes liver injury is unknown. Some ingredients contained in this supplement (green tea, Aloe vera, noni and goji) are linked to hepatic injury. To our knowledge, this is the first report of hepatotoxicity associated with Euforia.

  17. Viral blips during long-term treatment with standard or double dose lamivudine in HBe antigen negative chronic hepatitis B

    2007-01-01

    AIM: To evaluate safety and effect on hepatitis B virus (HBV) suppression of a long-term treatment with lamivudine (LAM) at standard (100 mg/d) or double (200 mg/d) dose in chronic hepatitis B. METHODS: This was a case study with matched controls (1:3) in patients with chronic hepatitis B with anti-Hbe antibodies. RESULTS: Twelve patients received LAM 200 mg/d and 35 LAM 100 mg/d, for a median of 28 mo. A primary response (PR; I.e. Negative HBV-DNA with Amplicor assay) was achieved in 100% of LAM-200 patients and 83% of LAM-100 patients. A virological breakthrough occurred in 16.7 and 24.7%, respectively, of the PR-patients, with the appearance of typical LAM resistance mutations in all but one patient. Viremia blips (I.e. Transient HBV-DNA below 80 IU/Ml in patients who tested negative at Amplicor assay) were detected using a real time polymerase chain reaction (PCR) and occurred in seven out of nine patients with subsequent BT and in four out of 32 patients with end-of-study response (77.7% vs 12.5%; P = 0.001) at chi-square test). At the end of the study, 51.4% of LAM-100 patients and 83.3% of LAM-200 patients had remained stably HBV-DNA negative. Double-dose LAM was well tolerated. CONCLUSION: Long-term treatment of anti-Hbe positive chronic hepatitis B with double dose lamivudine causes a more profound and stable viral suppression as compared to conventional treatment.

    2008-12-01

    Full Text Available Abstract Background Tanzania is currently scaling-up access to anti-retro viral therapy (ART to reach as many eligible persons as possible. Hepatitis viral co-infections are known to influence progression, management as well as outcome of HIV infection. However, information is scarce regarding the prevalence and predictors of viral hepatitis co-infection among HIV-infected individuals presenting at the HIV care and treatment clinics in the country. Methods A cross-sectional study conducted between April and September 2006 enrolled 260 HIV-1 infected, HAART naïve patients aged ≥18 years presenting at the HIV care and treatment clinic (CTC of the Muhimbili National Hospital (MNH. The evaluation included clinical assessment and determination of CD4+ T-lymphocyte count, serum transaminases and serology for Hepatitis A, B and C markers by ELISA. Results The prevalence of anti HAV IgM, HBsAg, anti-HBc IgM and anti-HCV IgG antibodies were 3.1%, 17.3%, 2.3% and 18.1%, respectively. Dual co-infection with HBV and HCV occurred in 10 individuals (3.9%, while that of HAV and HBV was detected in two subjects (0.8%. None of the patients had all the three hepatitis viruses. Most patients (81.1% with hepatitis co-infection neither had specific clinical features nor raised serum transaminases. History of blood transfusion and jaundice were independent predictors for HBsAg and anti-HBc IgM positivity, respectively. Conclusion There is high prevalence of markers for hepatitis B and C infections among HIV infected patients seeking care and treatment at MNH. Clinical features and a raise in serum alanine aminotransferase were of limited predictive values for the viral co-infections. Efforts to scale up HAART should also address co-infections with Hepatitis B and C viruses.

    Hepatitis C virus (HCV) is a major cause of hepatitis world-wide. The majority of infected individuals develop chronic hepatitis which can then progress to liver cirrhosis and hepatocellular carcinoma. Spontaneous viral clearance occurs in about 20%-30% of acutely infected individuals and results in resolution of infection without sequaelae. Both viral and host factors appear to play an important role for resolution of acute infection. A large body of evidence suggests that a strong, multispecific and long-lasting cellular immune response appears to be important for control of viral infection in acute hepatitis C. Due too the lack of convenient neutralization assays,the impact of neutralizing responses for control of viral infection had been less defined. In recent years, the development of robust tissue culture model systems for HCV entry and infection has finally allowed study of antibody-mediated neutralization and to gain further insights into viral targets of host neutralizing responses.In addition, detailed analysis of antibody-mediated neutralization in individual patients as well as cohorts with well defined viral isolates has enabled the study of neutralizing responses in the course of HCV infection and characterization of the impact of neutralizing antibodies for control of viral infection. This review will summarize recent progress in the understanding of the molecular mechanisms of antibody-mediated neutralization and its impact for HCV pathogenesis.(C) 2007 The WJG Press.
