    Full Text Available 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 cholestatic hepatitis diagnosed based on a positive serologic test (IgM and molecular detection of parvovirus B19 DNA in peripheral blood. Parvovirus B19 infection should be considered in the differential diagnosis of patient presenting with acute hepatitis of unknown etiology.

    Infectious mononucleosis is one of the major clinical manifestations of Epstein-Barr virus infection. In this syndrome, elevation of liver transaminase levels is common but cholestasis is rare, with few cases described in the literature. We present the case of a 14-year-old female adolescent, admitted to the Emergency Room with fever, odynophagia and cervical adenomegaly. She was treated with amoxicillin and two days later he presented with jaundice. The analytical evaluation was compatible with cholestatic hepatitis and abdominal ultrasound revealed hepatosplenomegaly without dilatation of the bile ducts. The diagnosis of Epstein-Barr virus infection was confirmed by the presence of serological markers. This case aims to raise awareness of a rare manifestation of a common infectious agent and, consequently, to the inclusion of acute Epstein-Barr virus infection in the differential diagnosis of pediatric cholestatic hepatitis.

    Full Text Available Antithyroid medications are one of the treatment options for Graves′ disease. Carbimazole is widely used as the drug of choice, except in pregnancy, where propythiouracil is preferred by many. It is generally well-tolerated. Its side-effects include allergy, upper gastrointestinal upset, a rare occurrence of granulocytosis, and others. Hepatitis is another rare, but serious side-effect. We report a healthy 30-year-old male patient with Graves′ disease, who developed cholestatic jaundice after Carbimazole therapy for four months. He made a full recovery after the drug was discontinued. An idiosyncratic mechanism seemed likely.

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

    2017-11-01

    The use of anabolic steroids is prevalent in recreational athletes. This case report describes a young amateur bodybuilder who was referred to our outpatient clinic with jaundice and loss of appetite due to cholestatic hepatitis. Additional tests including a liver biopsy made it likely that the hepatitis was caused by the injectable anabolic steroid trenbolone enanthate. Cholestatic hepatitis may not be limited to the use of oral anabolic-androgenic steroids, as is widely assumed. Therefore, and because of other side effects, the recreational use of all forms of anabolic steroids should be discouraged.

    Full Text Available Abstract Typhoid fever is a very common infectious disease, particularly in developing countries such as Sri Lanka. Although multiple organs are known to be affected by the disease, hepatic involvement could be considered the most important as studies have showed that it is associated with a higher relapse rate. We report a young patient who presented with fever and jaundice and found to have cholestatic hepatitis secondary to typhoid fever.

    Full Text Available Abstract Introduction Oxycodone is a widely-used semisynthetic opioid analgesic that has been used for over eighty years. Oxycodone is known to cause side effects such as nausea, pruritus, dizziness, constipation and somnolence. As far as we are aware cholestatic hepatitis as a result of oxycodone use has not been reported so far in the world literature. Case presentation A 34-year-old male presented with cholestatic jaundice and severe pruritus after receiving oxycodone for analgesia post-T11 vertebrectomy. Extensive laboratory investigations and imaging studies did not reveal any other obvious cause for his jaundice and a liver biopsy confirmed canalicular cholestatis suggestive of drug-induced hepatotoxicity. The patient's symptoms and transaminases normalised on withdrawal of oxycodone confirming that oxycodone was the probable cause of the patient's hepatotoxicity. Conclusion We conclude that cholestatic hepatitis is possibly a rare side effect of oxycodone use. Physicians should be aware of the possibility of this potentially serious picture of drug-induced hepatotoxicity.

    Full Text Available Introduction Cholestatic hepatitis is frequently a drug-related syndrome. We describe the case of a 57-year-old man who developed cholestatic hepatitis two months after starting therapy with ticlopidine following a carotid endarterectomy.Materials and methods The patient presented with anorexia, nausea, and dark-colored urine. The work-up included laboratory tests and imaging studies of the liver (ultrasound and magnetic resonance imaging. The authors analyze the case using the scale developed by Maria and Victorino for the diagnosis of drug-induced hepatitis, the Naranjo algorithm for adverse drug reactions, and the RUCAM algorithm for causality assessment of hepatotoxicity. They also review data from the MedLine database on cases of ticlopidine-induced cholestatic hepatitis reported during the period 1982–2011.Results Bilirubin, aminotransferases, alkaline phosphatases, and gamma glutamyl transpeptidase levels were elevated at admission and progressively declined after ticlopidine was discontinued. The absence of biliary obstruction at ultrasonography and magnetic resonance cholangiography, the negative results of viral and immunologic tests, and the resolution of the syndrome after discontinuation of the drug all suggested ticlopidine-induced hepatotoxicity. The assessment of this case with toxicity algorithms confirmed that a causal link to ticlopidine was “probable” or “highly probable.” The patient was treated with ursodesoxycholic acid, clopidogrel (75 mg/day, and (after the laboratory parameters had normalized rosuvastatin (10 mg/day. No further clinical and laboratory abnormalities have been observed during two month follow-up.Discussion The toxicity of ticlopidine is well established: our review revealed reports of 57 cases of ticlopidine-induced cholestatic hepatitis during the period 1982–2011. The mechanisms underlying the toxic effects of this drug are not clear, but they are probably related to the chemical structure

    2014-05-01

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

    To evaluate the frequency of cholestatic pattern in patients with autoimmune hepatitis (AIH) and to identify predictive factors associated with the development of the overlap syndrome. Eighty-two consecutive patients diagnosed with AIH at the referral centre between January 1998 and June 2002 were included in the study. The new scoring system modified by the International Autoimmune Hepatitis Group was used to classify patients as definite/probable. Overlap syndrome was considered when the patient had clinical, serological and histological characteristics of two conditions: AIH and primary biliary cirrhosis (PBC) or AIH and primary sclerosing cholangitis (PSC). From the 82 AIH patients (76 female and six male), 84.1% presented definite AIH (> 15 points) and 15.9% probable AIH (10 - 15 points). The frequency of the overlap syndrome was 20%: 13% with PBC and 7% with PSC. In the univariate analysis the overlap syndrome was associated with male gender (P = 0.01), age < 35 years (P < 0.0001), histopathological aspect of cholestasis (P < 0.0001), suboptimal response to treatment (P < 0.0001) and probable AIH (P < 0.0001). Age < 35 years, probable AIH and the absence of anti-nuclear antibody (ANA) have been identified as independent indicators of the overlap diagnosis by the logistic regression analysis. Patients with overlap syndrome between AIH and primary cholestatic liver disease are frequently diagnosed in clinical practice, representing 20% of AIH cases in our study. The independent predictive factors associated with the diagnosis of overlap syndrome are young age, ANA(-) profile, and probable diagnosis according with the scoring system for AIH.

  14. Urinary Elimination of Bile Acid Glucuronides under Severe Cholestatic Situations: Contribution of Hepatic and Renal Glucuronidation Reactions

    Directory of Open Access Journals (Sweden)

    Martin Perreault

    2018-01-01

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

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

    Full Text Available Pegvisomant (PEGv is a growth hormone receptor antagonist approved for the treatment of acromegaly; one of its documented adverse effects is reversible elevation of hepatic enzymes. We report a 39-year-old male acromegalic patient with a pituitary macroadenoma who underwent transsphenoidal surgery. The patient’s condition improved but GH and IGF-I levels did not normalize; as a consequence, we first administered dopamine agonists and then somatostatin receptor ligands (SRLs with poor response. PEGv 15 mg every other day was added to lanreotide 120 mg monthly. The patient developed a severe hepatitis five months after starting the combination therapy. Elevated ferritin, iron, and transferrin saturation suggested probable hepatitis due to haemochromatosis. We performed a liver biopsy which showed an acute cholestatic hepatitis consistent with toxic etiology. A heterozygous genotype UGT1A1​⁎28 polymorphism associated with Gilbert’s syndrome was also found in this Argentine patient. The predominant clinical presentation resembled an acute cholestatic hepatitis associated with severe hemosiderosis, a different and new pattern of PEGv hepatotoxicity.

    Sortilin 1 (Sort1) is an intracellular trafficking receptor that mediates protein sorting in the endocytic or secretory pathways. Recent studies revealed a role of Sort1 in the regulation of cholesterol and bile acid (BA) metabolism. This study further investigated the role of Sort1 in modulating BA detoxification and cholestatic liver injury in bile duct ligated mice. We found that Sort1 knockout (KO) mice had attenuated liver injury 24 h after bile duct ligation (BDL), which was mainly attributed to less bile infarct formation. Sham-operated Sort1 KO mice had about 20% larger BA pool size than sham-operated wildtype (WT) mice, but 24 h after BDL Sort1 KO mice had significantly attenuated hepatic BA accumulation and smaller BA pool size. After 14 days BDL, Sort1 KO mice showed significantly lower hepatic BA concentration and reduced expression of inflammatory and fibrotic marker genes, but similar degree of liver fibrosis compared with WT mice. Unbiased quantitative proteomics revealed that Sort1 KO mice had increased hepatic BA sulfotransferase 2A1, but unaltered phase-I BA metabolizing cytochrome P450s or phase-III BA efflux transporters. Consistently, Sort1 KO mice showed elevated plasma sulfated taurocholate after BDL. Finally, we found that liver Sort1 was repressed after BDL, which may be due to BA activation of farnesoid x receptor. In conclusion, we report a role of Sort1 in the regulation of hepatic BA detoxification and cholestatic liver injury in mice. The mechanisms underlying increased hepatic BA elimination in Sort1 KO mice after BDL require further investigation. © The Author 2017.

    Objective: To investigate differentiation direction of hepatic progenitor cells (HPCs) in cholestatic liver fibrosis (CLF), and the role of Notch signaling pathway in the differentiation of HPCs. Methods: A CLF rat model was established by bile duct ligation (BDL) followed by monitoring changes of Notch signal pathway and the cellular origin of proliferating cholangiocytes. After intraperitoneal injection of DAPT (a Notch signaling inhibitor) after bile duct ligation, the progress of liver fibrosis and the proliferation of cholangiocytes after inhibition of the Notch pathway were analyzed. Results: Data showed that bile duct proliferation gradually increased along with inflammatory cell infiltration and proliferating bile duct cells surrounded by abundant collagen in the BDL group. Immunostaining confirmed markedly increased expression of CK19, OV6, Sox9 and EpCAM. In addition, RT-PCR results showed that Notch signaling pathway was activated significantly. Once the Notch signaling pathway was inhibited by DAPT, bile duct proliferation markedly suppressed along with significantly decreased the mRNA expression of CK19, OV6, Sox9 and EpCAM, compared with BDL group [(10.2±0.7) vs . (22.3±0.8), (7.6±1.5) vs . (18.1±3.7), (1.4±0.4) vs . (4.1±1.1), (1.3±0.3) vs . (5.0±1.4), respectively, P liver fibrosis was also reduced significantly. Conclusion: Notch signaling activation is required for HPCs differentiation into cholangiocytes in CLF and inhibition of the Notch signaling pathway may offer a therapeutic option for treating CLF.

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

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

    Cholestatic liver diseases include a group of diverse disorders with different epidemiology, pathophysiology, clinical course, and prognosis. Despite significant advances in the clinical care of patients with cholestatic liver diseases, liver transplant (LT) remains the only definitive therapy for end-stage liver disease, regardless of the underlying cause. As per the United Network for Organ Sharing database, the rate of cadaveric LT for cholestatic liver disease was 18% in 1991, 10% in 2000, and 7.8% in 2008. This review summarizes the available evidence on various common and rare cholestatic liver diseases, disease-specific issues, and pertinent aspects of LT. Copyright © 2013 Elsevier Inc.

The cause of the injury is unknown, but the identification of serum autoantibodies makes an autoimmune aetiology attractive. The core study on which this commentary is based used novel cloning and serum screening technologies in order to identify new public and private autoantibodies in sera from 12 patients with CFA. Largely negative conclusions were drawn from that study. However, we suggest that the prevalence of autoantibodies may have been underestimated, that the study was timely and that this approach is worth pursuing further.

    Frontal fibrosing alopecia (FFA) is a rare dermatologic disease that causes scarring and hair loss and is increasing in prevalence worldwide. FFA patients typically present with hair loss in the frontal scalp region and eyebrows which may be associated with sensations of itching or burning. FFA is a clinically distinct variant of lichen planopilaris (LPP) that affects predominantly postmenopausal women, although men and premenopausal women may also be affected. Early diagnosis and prompt treatment are necessary to prevent definitive scarring and permanent hair loss. Data from retrospective studies indicate that 5-alpha-reductase inhibitors (5aRIs) are effective in stabilizing the disease. In our clinical experience, we have seen optimal results treating FFA patients with oral finasteride in conjunction with hydroxychloroquine, topical calcineurin inhibitors (tacrolimus) and excimer laser in patients with signs of active inflammation.

    Cholestatic liver injury results from impaired bile flow or metabolism and promotes hepatic inflammation and fibrogenesis. Toxic bile acids that accumulate in cholestasis induce apoptosis and contribute to early cholestatic liver injury, which is amplified by accompanying inflammation. The aim of the current study was to evaluate the role of the antiapoptotic caspase 8-homolog cellular FLICE-inhibitory (cFLIP) protein during acute cholestatic liver injury. Transgenic mice exhibiting hepatocyte-specific deletion of cFLIP (cFLIP -/- ) were used for in vivo and in vitro analysis of cholestatic liver injury using bile duct ligation (BDL) and the addition of bile acids ex vivo. Loss of cFLIP in hepatocytes promoted acute cholestatic liver injury early after BDL, which was characterized by a rapid release of proinflammatory and chemotactic cytokines (TNF, IL-6, IL-1β, CCL2, CXCL1, and CXCL2), an increased presence of CD68 + macrophages and an influx of neutrophils in the liver, and resulting apoptotic and necrotic hepatocyte cell death. Mechanistically, liver injury in cFLIP -/- mice was aggravated by reactive oxygen species, and sustained activation of the JNK signaling pathway. In parallel, cytoprotective NF-κB p65, A20, and the MAPK p38 were inhibited. Increased injury in cFLIP -/- mice was accompanied by activation of hepatic stellate cells and profibrogenic regulators. The antagonistic caspase 8-homolog cFLIP is a critical regulator of acute, cholestatic liver injury. NEW & NOTEWORTHY The current paper explores the role of a classical modulator of hepatocellular apoptosis in early, cholestatic liver injury. These include activation of NF-κB and MAPK signaling, production of inflammatory cytokines, and recruitment of neutrophils in response to cholestasis. Because these signaling pathways are currently exploited in clinical trials for the treatment of nonalcoholic steatohepatitis and cirrhosis, the current data will help in the development of novel pharmacological

    Aims: To systematically evaluate the literature for evidence to support the use of bile acids in non-cholestatic liver conditions. Methods: Searches were conducted on the databases of Medline (1948-March 31, 2015), Embase (1980-March 31, 2015) and the Cochrane Central Register of Controlled Trials, and on Google and Google Scholar to identify articles describing ursodeoxycholic acid (UDCA) and its derivatives for non-cholestatic hepatic indications. Combinations of the following search terms were used: ursodeoxycholic acid, ursodiol, bile acids and/or salts, non alcoholic fatty liver, non alcoholic steatohepatitis, fatty liver, alcoholic hepatitis, alcohol, liver disease, autoimmune, autoimmune hepatitis, liver transplant, liver graft, transplant rejection, graft rejection, ischemic reperfusion injury, reperfusion injury, hepatitis B, hepatitis C, viral hepatitis, chronic hepatitis, acute hepatitis, transaminases, alanine transaminase, liver enzymes, aspartate aminotransferase, gamma-glutamyl transferase, gamma-glutamyl transpeptidase, bilirubin, alkaline phosphatase. No search limits were applied. Additionally, references of the included studies were reviewed to identify additional articles. Results: The literature search yielded articles meeting inclusion criteria for the following indications: non-alcoholic fatty liver disease (n = 5); alcoholic liver disease (n = 2); autoimmune hepatitis (n = 6), liver transplant (n = 2) and viral hepatitis (n = 9). Bile acid use was associated with improved normalization of liver biochemistry in non-alcoholic fatty liver disease, autoimmune hepatitis and hepatitis B and C infections. In contrast, liver biochemistry normalization was inconsistent in alcoholic liver disease and liver transplantation. The majority of studies reviewed showed that normalization of liver biochemistry did not correlate to improvement in histologic disease. In the prospective trials reviewed, adverse effects associated with the bile acids were limited

HCV is the leading cause of liver transplantation in the USA and comes with a myriad of complications that increase morbidity and mortality. This review focuses on patient follow-up, spanning from before the liver transplant occurs to the patient's long-term health. Pretransplant, both donor and recipient variables, must be carefully chosen to ensure optimal surgical success. Risk factors must be identified and HCV viral load must be reduced to a minimum. In addition to standard transplant complications, HCV patients suffer from additional problems, such as fibrosing cholestatic hepatitis and widespread viremia. Physicians must focus on the balance of immunosuppressive and antiviral medications, while considering possible side effects from these potent drugs. Over the years following surgery, physicians must identify any signs of failing liver health, as HCV-positive patients have an increased risk for cirrhosis and certain life-threatening malignancies.

    Norursodeoxycholic acid (norUDCA) is a side-chain-shortened derivative of ursodeoxycholic acid with relative resistance to amidation, which enables its cholehepatic shunting. Based on its specific pharmacologic properties, norUDCA is a promising drug for a range of cholestatic liver and bile duct disorders. Recently, norUDCA has been successfully tested clinically in patients with primary sclerosing cholangitis (PSC) as first application in patients. Moreover, hepatic enrichment of norUDCA facilitates direct therapeutic effects on both parenchymal and non-parenchymal liver cells, thereby counteracting cholestasis, steatosis, hepatic inflammation and fibrosis, inhibiting hepatocellular proliferation, and promoting autophagy. This may open its therapeutic use to other non-cholestatic and metabolic liver diseases. This review article is a summary of a lecture given at the XXIV International Bile Acid Meeting (Falk Symposium 203) on "Bile Acids in Health and Disease" held in Düsseldorf, on June 17-18, 2016 and summarizes the recent progress of norUDCA as novel therapeutic approach in cholestatic and metabolic liver disorders with a specific focus on PSC. © 2017 S.

    Full Text Available Pruritus can be a prominent symptom  in patients with chronic liver disorders, especially those  with cholestasis,  and  substantially  affects  quality  of life. Management of pruritus  in cholestatic  liver diseases  remains  a  complicated   medical  problem. The review article deals with pathophysiological mechanisms of pruritus in cholestatic liver diseases, in particular, with the role of bile acids, endogenous opioids, serotonin, and histamine. There is new data on the key pathophysiological elements, such as neuronal activation lysophosphatidic acid and autotaxin, an enzyme that produces lysophosphatidic acid and whose serum activity is associated with the intensity of pruritus. Pathophysiology-based management approaches include administration of anionic exchange resin cholestyramine, ursodeoxycholic acid, rifampicin agonists, an opioid antagonist naltrexone and a  serotonin-reuptake inhibitor sertraline. These agents are recommended for the use as a stepped treatment algorithm. Patients who do not respond to these therapies can become candidates for albumin dialysis, plasmapheresis, ultraviolet B phototherapy, or need some other individualized approaches. New knowledge on the pathophysiology of pruritus may potentially result in the development of new agents for cholestatic pruritus.

Several studies indicated that YCHT may improving hepatic triglyceride metabolism and anti-apoptotic response as well as decreasing oxidative stress .However, little is known about the role of YCHT in chlorpromazine (CPZ) -induced chlolestatic liver injury. Therefore, we aimed to facilitate the understanding of the pathogenesis of cholestatic liver injury and evaluate the effect of Yin-Chen-Hao-Tang (YCHT) on chlorpromazine (CPZ)-induced cholestatic liver injury in rats based on the change of bile acids (BAs) and free fatty acids (FFAs) alone with the biochemical indicators and histological examination. We conducted an experiment on CPZ-induced cholestatic liver injury in Wistar rats with and without YCHT for nine consecutive days. Serum levels of alanine aminotransferase (ALT), aspartate aminotransferase (AST), albumin (ALB), total bilirubin (TBIL), total cholesterol (TC), triglycerides (TG), low density lipoprotein-cholesterol (LDL-C) were measured to evaluate the protective effect of YCHT against chlorpromazine (CPZ)-induced cholestatic liver injury. Histopathology of the liver tissue showed that pathological injuries were relieved after YCHT pretreatment. In addition, ultra-performance lipid chromatography coupled with quadrupole mass spectrometry (UPLC-MS) and gas chromatography coupled with mass spectrometry (GC-MS) was applied to determine the content of bile acids, free fatty acids, respectively. Obtained data showed that YCHT attenuated the effect of CPZ-induced cholestatic liver injury, which was manifested by the serum biochemical parameters and histopathology of the liver tissue. YCHT regulated the lipid levels as indicated by the reversed serum levels of TC, TG, and LDL-C. YCHT also regulated the disorder of BA and FFA metabolism by CPZ induction. Results indicated that YCHT exerted a protective effect on CPZ-induced cholestasis liver injury. The variance of

    A cholestatic liver disease presents one of the most common liver diseases and can potentially progress to cirrhosis or even cholangiocarcinoma. Conventional techniques are insufficient to precisely describe the complex internal structure, heterogeneous cell populations and the dynamics of biological processes of the liver. Currently, the methods of multiphoton and fluorescence lifetime imaging microscopy are actively introducing to biomedical research. Those methods are extremely informative and non-destructive that allows studying of a large number of processes occurring inside cells and tissues, analyzing molecular cellular composition, as well as evaluating the state of connective tissue fibers due to their ability to generate a second optical harmonic. Multiphoton and FLIM microscopy do not need additional staining of samples or the incorporation of any markers to study metabolism, lipid composition, microstructure analysis, evaluation of fibrous structures. These parameters have pronounced changes in hepatocytes of liver with common pathological diseases. Thereby in this study we investigated metabolic changes in the healthy and cholestatic liver based on the fluorescence of the metabolic co-factors NAD(P)H and FAD by multiphoton microscopy combined with FLIM. To estimate the contribution of energy metabolism and lipogenesis in the observed changes of the metabolic profile, a separate analysis of NADH and NADPH was presented. The data can be used to develop new criteria for the identification of hepatic pathology at the level of hepatocyte changes directed to personalized medicine in the future.

    Cilostazol is a phosphodiesterase III inhibitor increases adenosine 3', 5'-cyclic monophosphate (cyclic AMP) level which inhibits hepatic stellate cell activation. Its pharmacological effects include vasodilation, inhibition of vascular smooth muscle cell growth, inhibition of platelet activation and aggregation. The aim of the current study was to determine the effects of early administration of low dose cilostazol on cholestatic liver injury induced by common bile duct ligation (CBDL) in rat. Male Wistar rats (180-200g) were divided into three groups: Group A; simple laparotomy group (sham). Group B; CBDL, Group C; CBDL rats treated with cilostazol (9mg/kg daily for 21 days). Six rats from each group were killed by the end of weeks one and three after surgery, livers and serum were collected for biochemical and histopathological studies. Aspartate aminotransferase, alanine aminotransferase, gama glutamyl transferase, alkaline phosphatase and total bilirubin serum levels decreased in the cilostazol treated rats, when compared with CBDL rats. The hepatic levels of tumor necrosis factor-alpha, transforming growth factor-beta, and platelet derived growth factor-B were significantly lower in cilostazol treated rats than that in CBDL rats. Cilostazol decreased vascular endothelial growth factor level and hemoglobin content in the livers. Cilostazol significantly lowered portal pressure, inhibited ductular proliferation, portal inflammation, hepatic fibrosis and decreased hepatic hydroxyproline contents. Administration of cilostazol in CBDL rats improved hepatic functions, decreased ductular proliferation, ameliorated portal inflammation, lowered portal hypertension and reduced fibrosis. These effects of cilostazol may be useful in the attenuation of liver injury in cholestasis. Copyright © 2015 Elsevier B.V. All rights reserved.

    Full Text Available Hemophagocytic lymphohistiocytosis (HLH is an uncommon disease that often presents with nonspecific findings. A high index of suspicion is necessary to make a prompt diagnosis and prevent fatal disease. A 45-year-old man presented with fever, hypotension, abdominal pain, nausea, and vomiting. Imaging showed hepatosplenomegaly and laboratory tests revealed pancytopenia, increased ferritin, and a cholestatic pattern of injury with elevated alkaline phosphatase and total bilirubin. Due to a history of Crohn disease, systemic lupus erythematous, and rheumatoid arthritis, the patient was on immunosuppressants, including infliximab. After multiple negative cultures, persistent fever, and days of empiric broad spectrum antibiotics, our differential shifted to fever of unknown origin. A liver wedge biopsy revealed areas of sinusoidal dilatation with enlarged, activated macrophages containing erythrocytes and intracytoplasmic iron, consistent with hemophagocytosis due to HLH. The portal tracts showed mixed lymphoplasmacytic inflammation, a prominent bile ductular reaction, periportal fibrosis, and scattered large cells with occasional binucleation and prominent nucleoli. These cells stained positive for Epstein-Barr virus encoding region in situ hybridization, PAX5, CD15, and CD30, and hepatic involvement by classic Hodgkin lymphoma was diagnosed and determined to be the cause of the HLH and cholestatic pattern of injury. Simultaneously, a bone marrow biopsy showed diffuse involvement by Hodgkin lymphoma with a similar staining pattern. Aggressive treatment failed and the patient succumbed to multiorgan failure. HLH is a rare, potentially fatal disease, with nonspecific signs and symptoms, and should be considered in any patient presenting with fever and pancytopenia, especially if they are immune compromised.

Bronchial tree was colonised permanently in five patients: Pseudomonas aeruginosa in four and Staphilococcus aureus in four (three patients affected by both agents simultaneously.The main causes of exacerbation were respiratory infections and haemoptysis.Non-respiratory involvement was variable. Four patients had digestive involvement (one with hepatic cirrhosis, one had renal failure and only one had a sperm count to document infertility. Four patients had osteo-paenia. Treatment included chest physiotherapy, bronchodilators, dornase alfa, mucolytics, digestive enzymes, vitamins, antibiotics and oxygen therapy. At review, one had left follow-up, one had died, one was awaiting lung transplant and the others evidenced no difference in clinical characteristics. In this group of patients the severity of the pulmonary disease was not related to a late diagnosis. It can be explained by the diversity of cystic fibrosis presentation in adultsRev Port Pneumol 2007; XIII (3: 335-347 Palavras-chave: Fibrose quística, adultos, revisão, Key-words: Cystic fibrosis, adults, review

    A 44-year-old female patient visited our emergency room for hemoptysis and refractory chest wall pain of 2 months duration. She had no history of smoking or other medical conditions. Chest CT scan showed homogenously enhancing soft tissue mass without calcification at the left pulmonary hilum. Encasing and compression of the left lower pulmonary artery by the mass had resulted in pulmonary infarction in the left lower lobe. Laboratory tests for tuberculosis, fungus, and vasculitis were all negative. The patient underwent surgical biopsy and resection of infarcted left lower lobe that was histopathologically confirmed as fibrosing mediastinitis. Herein, we reported a rare case of surgically confirmed and treated localized fibrosing mediastinitis causing pulmonary infarction.

    Full Text Available Background: Once it is established that a jaundiced infant has direct hyperbilirubinemia, the principal diagnostic concern is to differentiate hepatocellular from obstructive cholestasis. Traditional tests such as ultrasonography, percutaneous liver biopsy and technetium 99 m hepatobiliary iminodiacetic acid (HIDA scan are often not sufficiently discriminating. Definitive exclusion of biliary atresia (BA in the infant with cholestatic jaundice usually requires mini-laparotomy and intra-operative cholangiography. This approach has many drawbacks because those sick infants are subjected to a time-consuming procedure with the probability of negative surgical exploration. Aim of the Study: The aim of this study was to determine the feasibility of laparoscopic-guided cholecystocholangiography (LGCC and its accuracy and safety in the diagnosis of BA and thus preventing unnecessary laparotomy in infants whose cholestasis is caused by diseases other than BA. Patients and Methods: Twelve cholestatic infants with direct hyperbilirubinemia subjected to LGCC (age, 7–98 days; mean, 56 days after ultrasound scan and (99 mTc HIDA scan and percutaneous liver biopsy failed to provide the definitive diagnosis. Results: One patient had completely absent gall bladder (GB so the laparoscopic procedure was terminated and laparotomy was done (Kasai operation. Four patients had small size GB; they underwent LGCC that showed patent common bile duct with atresia of common hepatic duct, so laparotomy and Kasai operation was performed. Seven patients had well-developed GB, LGCC revealed patent biliary tree, so laparoscopic liver biopsies were taken for histopathology. Five of those patients had neonatal hepatitis, and two had cholestasis as a complication of prolonged TPN. No perioperative complications or mortalities were recorded. Conclusion: When the diagnosis neonatal cholestasis remains elusive after traditional investigations, LGCC is an accurate and simple method

    There is increasing interest in ventilation perfusion (V/Q) imaging in cryptogenic fibrosing alveolitis because of the data these scans provide on the dynamic V/Q relationships in such patients undergoing single lung transplantation. We analysed the V/Q scans of 45 consecutive patients with advanced cryptogenic fibrosing alveolitis being considered for single lung transplantation. Scans were classified according to the presence, severity and degree of matching of defects in ventilation and perfusion images and the results were compared with the data obtained from lung function tests. Ventilation images showed defects in 13 (29%) and ''washout delay'' in 15 (33%) patients; 10 (22%) patients had asymmetric distribution of ventilation with one lung receiving >60% of total ventilation. Perfusion images showed normal perfusion in 8 (18%), mild defects in 18 (40%) and major defects in 19 (42%) patients. The distribution of perfusion between lungs was significantly asymmetric in 20 (45%) patients. V/Q images were matched in 15 (33%), mildly mismatched in 15 (33%) and severely mismatched in 15 (33%) patients, but the degree of V/Q mismatch did not show a relationship to KCO, PaO 2 or A-aO 2 gradient. The appearances were atypical of pulmonary embolism in eight patients. (Author)

    Approximately 95% of bile acids (BAs) excreted into bile are reabsorbed in the gut and circulate back to the liver for further biliary secretion. Therefore, pharmacological inhibition of the ileal apical sodium-dependent BA transporter (ASBT/SLC10A2) may protect against BA-mediated cholestatic liver and bile duct injury. Eight week old Mdr2(-/-) (Abcb4(-/-)) mice (model of cholestatic liver injury and sclerosing cholangitis) received either a diet supplemented with A4250 (0.01% w/w) - a highly potent and selective ASBT inhibitor - or a chow diet. Liver injury was assessed biochemically and histologically after 4weeks of A4250 treatment. Expression profiles of genes involved in BA homeostasis, inflammation and fibrosis were assessed via RT-PCR from liver and ileum homogenates. Intestinal inflammation was assessed by RNA expression profiling and immunohistochemistry. Bile flow and composition, as well as biliary and fecal BA profiles were analyzed after 1week of ASBT inhibitor feeding. A4250 improved sclerosing cholangitis in Mdr2(-/-) mice and significantly reduced serum alanine aminotransferase, alkaline phosphatase and BAs levels, hepatic expression of pro-inflammatory (Tnf-α, Vcam1, Mcp-1) and pro-fibrogenic (Col1a1, Col1a2) genes and bile duct proliferation (mRNA and immunohistochemistry for cytokeratin 19 (CK19)). Furthermore, A4250 significantly reduced bile flow and biliary BA output, which correlated with reduced Bsep transcription, while Ntcp and Cyp7a1 were induced. Importantly A4250 significantly reduced biliary BA secretion but preserved HCO3(-) and biliary phospholipid secretion resulting in an increased HCO3(-)/BA and PL/BA ratio. In addition, A4250 profoundly increased fecal BA excretion without causing diarrhea and altered BA pool composition, resulting in diminished concentrations of primary BAs tauro-β-muricholic acid and taurocholic acid. Pharmacological ASBT inhibition attenuates cholestatic liver and bile duct injury by reducing biliary BA

    Bone morphogenetic protein 9 (BMP9) interferes with liver regeneration upon acute injury, while promoting fibrosis upon carbon tetrachloride-induced chronic injury. We have now addressed the role of BMP9 in 3,5 diethoxicarbonyl-1,4 dihydrocollidine (DDC)-induced cholestatic liver injury, a model of liver regeneration mediated by hepatic progenitor cell (known as oval cell), exemplified as ductular reaction and oval cell expansion. WT and BMP9KO mice were submitted to DDC diet. Livers were examined for liver injury, fibrosis, inflammation and oval cell expansion by serum biochemistry, histology, RT-qPCR and western blot. BMP9 signalling and effects in oval cells were studied in vitro using western blot and transcriptional assays, plus functional assays of DNA synthesis, cell viability and apoptosis. Crosslinking assays and short hairpin RNA approaches were used to identify the receptors mediating BMP9 effects. Deletion of BMP9 reduces liver damage and fibrosis, but enhances inflammation upon DDC feeding. Molecularly, absence of BMP9 results in overactivation of PI3K/AKT, ERK-MAPKs and c-Met signalling pathways, which together with an enhanced ductular reaction and oval cell expansion evidence an improved regenerative response and decreased damage in response to DDC feeding. Importantly, BMP9 directly targets oval cells, it activates SMAD1,5,8, decreases cell growth and promotes apoptosis, effects that are mediated by Activin Receptor-Like Kinase 2 (ALK2) type I receptor. We identify BMP9 as a negative regulator of oval cell expansion in cholestatic injury, its deletion enhancing liver regeneration. Likewise, our work further supports BMP9 as an attractive therapeutic target for chronic liver diseases. © 2018 John Wiley & Sons A/S. Published by John Wiley & Sons Ltd.

    Full Text Available A fibrose cística é a doença genética letal mais comum em populações caucasianas e é caracterizada por infecções crônicas e recorrentes do pulmão, insuficiência pancreática e elevados níveis de cloro no suor. É uma doença de herança autossômica recessiva causada pela mutação no gene do Regulador da Condutância Transmembrana da Fibrose Cística, que induz o organismo a produzir secreções espessas e viscosas que obstruem os pulmões, o pâncreas e o ducto biliar. Muitos pacientes apresentam insuficiência pancreática, que leva a má-absorção de nutrientes especialmente de proteínas e lipídeos e a complicações gastrintestinais tais como prolapso retal, síndrome da obstrução intestinal, constipação e cirrose hepática. A fibrose cística normalmente é diagnosticada na infância, pelos programas de triagem neonatal ou pelo teste do suor. Devido aos vários sistemas envolvidos e à variabilidade e cronicidade da doença, uma abordagem multidisciplinar é essencial para auxiliar o paciente e sua família a compreenderem a doença e aderirem ao tratamento. A terapia atual da fibrose cística inclui a manutenção do estado nutricional, a remoção das secreções das vias aéreas com fisioterapia e mucolíticos, o uso de antibióticos para prevenção e tratamento de infecções, a prescrição de suplementos energéticos, dietas hiperlípidicas e hiperprotéicas, bem como a suplementação de minerais e vitaminas lipossolúveis.

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

    Polyhexamethyleneguanidine hydrochloride (PHMG) is an antimicrobial biocide of the guanidine family. In the period from August 2006 to May 2007, more than 12500 patients were admitted to hospital with a history of drinking illegal cheap "vodka" in 44 different regions in Russia, of whom 9.4% died. In reality, the "vodka" was an antiseptic liquid composed of ethanol (≈93%), diethyl phthalate, and 0.1-0.14% PHMG (brand name "Extrasept-1"). We performed an analysis of the clinical features and outcome in four poisoning treatment centers in the cities of Perm, Ekaterinburg, Irkutsk, and Khabarovsk. A total of 579 patients (215 females and 364 males) with similar symptoms were included. The main symptoms on admission included jaundice (99.7%), skin itch (78.4%), weakness (96%), anorexia (65.8%), dizziness (65.3%), nausea (54.8%), vomiting (22.6%), stomach ache (52.7%), diarrhea (32%), and fever (50%). Mild symptoms were found in 2.5% of cases, moderate in 63%, and severe in 34.5%. Laboratory results were (mean ± SD): total bilirubin 249 ± 158 μmol/L, direct bilirubin 166 ± 97 μmol/L, cholesterol 14 ± 8 mmol/L, alanine aminotransferase 207 ± 174 IU/L, aspartate aminotransferase 174 ± 230 IU/L, alkaline phosphatase 742 ± 751 IU/L, and gamma-glutamyltranspeptidase 1199 ± 1095 IU/L. Patients generally recovered over a period of 1-5 months, although high levels of alkaline phosphatase and gamma-glutamyltranspeptidase were still found in all patients examined after 6 months. Sixty-one patients (10.5%) died between 23 and 150 days after poisoning. Local cholestasis, inflammatory infiltration, and fibrosis developing into cirrhosis were found by liver biopsy. Acute liver injury caused by PHMG-hydrochloride or PHMG in combination with either ethanol or diethyl phthalate can be characterized as cholestatic hepatitis with a severe inflammatory component causing high mortality.

    The risk of lung cancer is often reported to be increased for patients with cryptogenic fibrosing alveolitis (CFA). Vital status was sought for all 588 members of the British Thoracic Society (BTS) cryptogenic fibrosing alveolitis (CFA) study 11 years after entry to the cohort. Observed deaths due to lung cancer were compared with expected deaths using age-, sex- and period-adjusted national rates. The roles of reported asbestos exposure and smoking were also investigated. 488 cohort members (83%) had died; 46 (9%) were certified to lung cancer (ICD9 162). The standardised mortality ratio (SMR) was 7.4 (95% CI 5.4 to 9.9). Stratified analysis showed increased lung cancer mortality among younger subjects, men and ever smokers. Using an independent expert panel, 25 cohort members (4%) were considered to have at least moderate exposure to asbestos; the risk of lung cancer was increased for these subjects (SMR 13.1 (95% CI 3.6 to 33.6)) vs 7.2 (95% CI 5.2 to 9.7) for those with less or no asbestos exposure). Ever smoking was reported by 448 (73%) of the cohort and was considerably higher in men than in women (92% vs 49%; p<0.001). Most persons who died from lung cancer were male (87%), and all but two (96%) had ever smoked. Ever smokers presented at a younger age (mean 67 vs 70 years; p<0.001) and with less breathlessness (12% smokers reported no breathlessness vs 5% never smokers; p = 0.02). These findings confirm an association between CFA and lung cancer although this relationship may not be causal. The high rate of smoking and evidence that smokers present for medical attention earlier than non-smokers suggest that smoking could be confounding this association.

    Therapeutic voriconazole concentrations have a narrow window of effectiveness before causing cholestatic hepatitis. After undergoing 1 year of voriconazole therapy for pulmonary aspergillosis, a 44-year-old man began treatment with 30 mg lansoprazole for gastroesophageal reflux symptoms. Within 5 days of starting treatment with lansoprazole, the patient presented with fatigue, jaundice, and cholestatic hepatitis. The hepatitis promptly resolved after stopping lansoprazole treatment. Sixteen months later, the patient was given simvastatin therapy, as recommended by the American Diabetes Association to prevent cardiovascular disease for patients with diabetes who are aged >40 years and have one additional risk factor. Within 2 weeks of taking simvastatin, a 3-hydroxy-3-methylglutaryl CoA reductase (statin) therapy, the patient redeveloped fatigue, jaundice, and cholestatic hepatitis. He described both episodes of fatigue and jaundice similarly in terms of onset and intensity. Voriconazole is metabolized by both CYP2C19 and CYP3A4 isoenzymes. Lansoprazole is an inhibitor of the CYP2C19 isoenzyme. Competition between voriconazole and lansoprazole likely led to increased voriconazole serum concentration and acute cholestatic hepatitis in this patient. Simvastatin inhibits the CYP3A4 isoenzyme. After the patient took 10 mg simvastatin daily for 2 weeks, cholestatic hepatitis occurred. The voriconazole concentration remained elevated (4.1 μg/ml) when measured 15 days after stopping simvastatin. The patient's Naranjo Adverse Drug Reaction Probability Scale score of 7 revealed that the cholestatic hepatitis was probably precipitated by lansoprazole. Likewise, the patient's Naranjo score of 9 also revealed that cholestatic hepatitis was attributable to a definite adverse drug reaction precipitated by the addition of simvastatin to the stable baseline regimen of voriconazole. In a single patient, two different inhibitors of the cytochrome P450 pathway stimulated voriconazole

    The sequence of events that lead to inflammation and fibrosing nonalcoholic steatohepatitis (NASH) is incompletely understood. Hence, we investigated the chronology of whole body, tissue, and cellular events that occur during the evolution of diet-induced NASH. Male C57Bl/6 mice were assigned to a fast-food (FF; high calorie, high cholesterol, high fructose) or standard-chow (SC) diet over a period of 36 wk. Liver histology, body composition, mitochondrial respiration, metabolic rate, gene expression, and hepatic lipid content were analyzed. Insulin resistance [homeostasis model assessment-insulin resistance (HOMA-IR)] increased 10-fold after 4 wk. Fibrosing NASH was fully established by 16 wk. Total hepatic lipids increased by 4 wk and remained two- to threefold increased throughout. Hepatic triglycerides declined from sixfold increase at 8 wk to threefold increase by 36 wk. In contrast, hepatic cholesterol levels steadily increased from baseline at 8 wk to twofold by 36 wk. The hepatic immune cell population altered over time with macrophages persisting beyond 16 wk. Mitochondrial oxygen flux rates of FF mice diet were uniformly lower with all the tested substrates (13-276 pmol·s -1 ·ml -1 per unit citrate synthase) than SC mice (17-394 pmol·s -1 ·ml -1 per unit citrate synthase) and was accompanied by decreased mitochondrial:nuclear gene copy number ratios after 4 wk. Metabolic rate was lower in FF mice. Mitochondrial glutathione was significantly decreased at 24 wk in FF mice. Expression of dismutases and catalase was also decreased in FF mice. The evolution of NASH in the FF diet-induced model is multiphasic, particularly in terms of hepatic lipid composition. Insulin resistance precedes hepatic inflammation and fibrosis. Mitochondrial dysfunction and depletion occur after the histological features of NASH are apparent. Collectively, these observations provide a unique overview of the sequence of changes that coevolve with the histological evolution of

    Aerobic fitness was evaluated in 25 women with fibrositis, by having them exercise to volitional exhaustion on an electronically braked cycle ergometer. Compared with published standards, greater than 80% of the fibrositis patients were not physically fit, as assessed by maximal oxygen uptake. Compared with matched sedentary controls, fibrositis patients accurately perceived their level of exertion in relation to oxygen consumption and attained a similar level of lactic acidosis, as assessed by their respiratory quotient and ventilatory threshold. Exercising muscle blood flow was estimated by 133-xenon clearance in a subgroup of 16 fibrositis patients and compared with that in 16 matched sedentary controls; the fibrositis patients exhibited reduced 133-xenon clearance. These results indicate a need to include aerobic fitness as a matched variable in future controlled studies of fibrositis and suggest that the detraining phenomenon may be of relevance to the etiopathogenesis of the disease

    Rationale: Assessment of disease activity in fibrosing alveolitis due to systemic sclerosis (FASSc) is difficult without using invasive investigation. A repeatable noninvasive method of assessing disease at a cellular level such as with positron emission tomography (PET) could be of great value in evaluating high-resolution changes in the pathological process. Objectives: To investigate whether the level of inflammatory cell traffic and lung density in FASSc, imaged in vivo by PET, is different to controls and whether they are associated with changes in pulmonary function indices. Methods: We used PET to measure lung density and tissue uptake of {sup 11}C-[R]-PK11195, a ligand that binds to receptors found in abundance in macrophages. Fifteen patients with FASSc were compared to seven controls. Results: A trend of reduced uptake of {sup 11}C-[R]-PK11195 was observed in FASSc patients (P=.09) and correlated inversely with lung density (r=-.62; P<.05), which was significantly elevated in FASSc [0.35{+-}0.02 vs. 0.23{+-}0.02 g/cc (mean{+-}S.E.M.); P<.005]. Conclusion: These results demonstrate that inflammatory cell traffic and lung density can be imaged in vivo in FASSc using PET, and that this approach might be of potential value in understanding, in situ, components of pathogenesis that may have value for prognosis.

    Interruption of the enterohepatic circulation of bile acids (BAs) may protect against BA-mediated cholestatic liver and bile duct injury. BA sequestrants are established to treat cholestatic pruritus, but their impact on the underlying cholestasis is still unclear. We aimed to explore the therapeutic effects and mechanisms of the BA sequestrant colesevelam in a mouse model of sclerosing cholangitis. Mdr2 -/- mice received colesevelam for 8 weeks. Gene expression profiles of BA homeostasis, inflammation and fibrosis were explored in liver, intestine and colon. Hepatic and faecal BA profiles and gut microbiome were analysed. Glucagon-like peptide 1 (GLP-1) levels in portal blood were measured by ELISA. Furthermore, Mdr2 -/- mice as well as wild-type 3,5-diethoxy-carbonyl-1,4-dihydrocollidine-fed mice were treated with GLP-1-receptor agonist exendin-4 for 2 weeks prior to analysis. Colesevelam reduced serum liver enzymes, BAs and expression of proinflammatory and profibrogenic markers. Faecal BA profiling revealed increased levels of secondary BAs after resin treatment, while hepatic and biliary BA composition showed a shift towards more hydrophilic BAs. Colonic GLP-1 secretion, portal venous GLP-1 levels and intestinal messenger RNA expression of gut hormone Proglucagon were increased, while ileal Fgf15 expression was abolished by colesevelam. Exendin-4 treatment increased bile duct mass without promoting a reactive cholangiocyte phenotype in mouse models of sclerosing cholangitis. Microbiota analysis showed an increase of the phylum δ-Proteobacteria after colesevelam treatment and a shift within the phyla Firmicutes from Clostridiales to Lactobacillus . Colesevelam increases faecal BA excretion and enhances BA conversion towards secondary BAs, thereby stimulating secretion of GLP-1 from enteroendocrine L-cells and attenuates liver and bile duct injury in Mdr2 -/- mice. © Article author(s) (or their employer(s) unless otherwise stated in the text of the article

    Background: Because of growing body of interest on the association between fibrosing idiopathic interstitial pneumonias (f-IIP) and ischaemic heart disease, we initiated this prospective study to evaluate the prevalence of asymptomatic coronary artery disease (CAD) in patients with f-IIP. Methods: Forty-two patients with f-IIP underwent noninvasive screening for CAD that included (a) a chest CT examination enabling calculation of the coronary artery calcium (CAC) score, then depiction of coronary artery stenosis; and (b) stress myocardial perfusion scintigraphy (MPS). Patients with significant coronary abnormalities, defined by a CAC score >400 or coronary artery stenosis >50% at CT and/or perfusion defect >5% at MPS, were referred to the cardiologist. Coronary angiography was indicated in presence of a perfusion defect >10% at MPS or significant left main or proximal left anterior descending stenosis whatever MPS findings. Results: Combining CT and MPS, significant abnormalities were detected in 32/42 patients (76%). The cardiologist: (a) did not consider further investigation in 21 patients (CT abnormalities but no ischaemia at MPS: 12/21; false-positive findings at MPS: 3/21; poor respiratory condition: 6/21); (b) proceeded to coronary angiography in 11 patients which confirmed significant stenoses in 5 patients (5/42; 12%). In the worst-case-scenario (i.e., inclusion of 6 patients with significant coronary artery abnormalities who were not investigated due to poor respiratory condition), the prevalence of CAD reached 26% (11/42). Conclusion: In the studied population of patients with f-IIP, asymptomatic CAD ranged between 12% and 26%

    Cryptogenic fibrosing alveolitis (CFA) is characterized by interstitial fibrosis and parenchymal inflammation. Eleven patients with CFA (10 proved by lung biopsy) were followed over 2 yr using clinical symptoms, radiographic change, and pulmonary function tests to adjust their treatment. Lung lavage, positron camera (PET) measurements of regional extravascular lung density (Dev), pulmonary blood volume (Vb), and the metabolic rate for 18F-deoxyglucose (MRglc), clearance of 99mTc-diethylenetriaminepentacetate (99mTc-DTPA) aerosol, and lung uptake of 67Ga were measured initially and at the end of the first year to give a profile of the inflammatory response. Compared with normal subjects, there was an increased percentage of neutrophils and eosinophils in the lung lavage, increased Dev (p less than 0.002) with no significant difference in Vb, increased MRglc (p less than 0.02), 99mTc-DTPA clearance (p less than 0.002), and 67Ga uptake (p less than 0.02). The smallest increases in Dev were seen in the two patients with most destruction shown by lung biopsy. There were inverse correlations between Dev and both FVC and TLC, but a direct correlation between Vb and transfer factor. 99mTc-DTPA clearance changed concordantly with clinical status and radiographic and respiratory function changes during the first year. If glucose utilization (MRglc) remained in the normal range between the initial and first yearly assessment, the patient improved or remained stable during the second year as shown by clinical status and radiographic and respiratory function measurements. If it rose or remained high, the patient's condition deteriorated

    Organising pneumonia (OP) is composed of loose granulation tissue plugs in distal airspaces; these disappear with steroid treatment. Recently a variant labelled 'cicatricial' OP has been described in which the granulation tissue organised to much denser fibrous tissue but still retained the usual pattern of OP. Here we report 10 patients thought to have an interstitial lung disease, and who on biopsy had a variant of cicatricial OP characterised by linear bands or small nodular masses of dense fibrous tissue that does not resemble ordinary OP. The bands/nodules were usually distributed randomly but occasionally resembled fibrotic non-specific interstitial pneumonia in local areas. Small foci of loose granulation tissue at the edge of the fibrotic bands sometimes mimicked fibroblast foci. Recognisable conventional OP was always present, but often in very small amounts. Four cases, including one patient with Ehlers-Danlos syndrome, showed formation of bone in the fibrotic bands and nodules. On computerised tomography (CT) scan of the chest some cases looked like typical OP, but some demonstrated only irregularly distributed linear opacities, sometimes with associated calcification. Follow-up imaging on six cases showed that the process either markedly improved or remained stable over time; no case had progressive disease. Cicatricial OP with this pathological pattern represents an uncommon form of OP that appears to be a generally benign process which may have persisting linear opacities on CT scan but that does not progress; however, it can be confused on biopsy and CT with a fibrosing interstitial pneumonia. © 2017 John Wiley & Sons Ltd.

    Frontal fibrosing alopecia is a variant of lichen planopilaris with marginal progressive hair loss on the scalp, eyebrows and axillae. We report a case of frontal fibrosing alopecia and lichen planus pigmentosus in a postmenopausal woman, that started with alopecia on the eyebrows and then on the frontoparietal region, with periocular and cervical hyperpigmentation of difficult management. The condition was controlled with systemic corticosteroid therapy and finasteride. Lichen planus pigmentosus is an uncommon variant of lichen planus frequently associated with frontal fibrosing alopecia in darker phototipes. It should be considered in patients affected by scarring alopecia with a pattern of lichen planopilaris and areas of skin hyperpigmentation revealing perifollicular hyperpigmentation refractory to multiple treatments. This case illustrates diagnostic and therapeutic challenge in face of scarring alopecia and perifollicular hyperpigmentation.

    Full Text Available Objetivos: nos últimos 70 anos, a fibrose cística emergiu da obscuridade para o reconhecimento como a mais importante doença hereditária, potencialmente letal, incidente na raça branca. Embora seja uma doença genética, na qual o defeito básico acomete células de vários órgãos, nem todos os indivíduos expressam respostas clínicas na mesma intensidade. Várias manifestações clínicas, principalmente pulmonares e digestivas, podem ocorrer durante a vida dos pacientes fibrocísticos. O objetivo deste artigo é propiciar ao pediatra geral uma visão atualizada dos principais assuntos referentes à fibrose cística. Fontes dos dados: revisão sistemática e atualizada em fonte de dados oficial (Medline. Síntese dos dados: foram revisados 79 artigos sobre fibrose cística, de periódicos internacionais, colocando, de modo atual e crítico, os principais eventos relacionados com a incidência, a fisiopatogenia, as manifestações clínicas, o diagnóstico e o tratamento da fibrose cística. Conclusões: apesar de não existir cura para essa doença, muitos conhecimentos novos sobre a etiologia e a fisiopatologia, adquiridos nas duas últimas décadas, propiciaram uma nova abordagem para o tratamento da fibrose cística. A compreensão dos mecanismos básicos da doença pulmonar, bem como das manifestações digestivas na fibrose cística, decorrente dos conhecimentos de pesquisas recentes, tem sido a chave para o aumento da sobrevida e a melhora da qualidade de vida dos pacientes.

    Full Text Available The connexin 32 (Cx32 is a protein that forms the channels that promote the gap junction intercellular communication (GJIC in the liver, allowing the diffusion of small molecules through cytosol from cell-to-cell. Hepatic fibrosis is characterized by a disruption of normal tissue architeture by cellular lesions, and may alter the GJIC. This work aimed to study the expression and distribution of Cx32 in liver fibrosis induced by the oral administration of dimethylnitrosamine in female Wistar rats. The necropsy of the rats was carried out after five weeks of drug administration. They presented a hepatic fibrosis state. Sections from livers with fibrosis and from control livers were submitted to immunohistochemical, Real Time-PCR and Western-Blot analysis to Cx32. In fibrotic livers the Cxs were diffusely scattered in the cytoplasm, contrasting with the control livers, where the Cx32 formed junction plaques at the cell membrane. Also it was found a decrease in the gene expression of Cx32 without reduction in the protein quantity when compared with controls. These results suggest that there the mechanism of intercellular communication between hepatocytes was reduced by the fibrotic process, which may predispose to the occurrence of a neoplastic process, taken in account that connexins are considered tumor suppressing genes.A conexina 32 (Cx32 é uma proteína que constitui os canais que promovem as comunicações intercelulares via junções comunicantes (CIJC no fígado, permitindo difusão de pequenas moléculas citoplasmáticas de uma célula à outra.

    We report a 14-months-old infant who had obstructive jaundice caused by idiopathic fibrosing pancreatitis. Ultrasonography and abdominal computed tomography showed dilatation of the intrahepatic ducts, common bile duct, and the pancreatic duct. Diffuse swelling of the pancreas was also noted on CT. At laparotomy, the head portion of the pancreas revealed a stony hard consistency, and proliferation of fibrotic tissue was confirmed pathologically. Idiopathic fibrosing pancreatitis is a very rare disease entity in childhood, but should be considered in the differential diagnosis of obstructive jaundice in children who demonstrate bile duct and pancreatic duct dilatation and/or diffuse pancreas swelling

    Organising pneumonia (OP) is usually promptly responsive to corticosteroid treatment. We describe a series of 3 cases of severe, progressive, biopsy-proven fibrosing OP causing respiratory failure. All cases presented with peribronchial and subpleural consolidations, had a fibro-inflammatory infiltrative component in the alveolar septa, and only had a partial and unsatisfactory response to corticosteroids. However, they responded to mycophenolic acid (MPA) treatment with resolution of respiratory failure as well as clinical and functional improvement. MPA as an additional treatment option for aggressive forms of fibrosing OP and interstitial lung disease needs to be further explored. © 2016 S. Karger AG, Basel.

    Recent studies confirmed a critical importance of c-Met signaling for liver regeneration by modulating redox balance. Here we used liver-specific conditional knockout mice (MetKO) and a nutritional model of hepatic steatosis to address the role of c-Met in cholesterol-mediated liver toxicity. Liver injury was assessed by histopathology and plasma enzymes levels. Global transcriptomic changes were examined by gene expression microarray, and key molecules involved in liver damage and lipid homeostasis were evaluated by Western blotting. Loss of c-Met signaling amplified the extent of liver injury in MetKO mice fed with high-cholesterol diet for 30 days as evidenced by upregulation of liver enzymes and increased synthesis of total bile acids, aggravated inflammatory response and enhanced intrahepatic lipid deposition. Global transcriptomic changes confirmed the enrichment of networks involved in steatosis and cholestasis. In addition, signaling pathways related to glutathione and lipid metabolism, oxidative stress and mitochondria dysfunction were significantly affected by the loss of c-Met function. Mechanistically, exacerbation of oxidative stress in MetKO livers was corroborated by increased lipid and protein oxidation. Western blot analysis further revealed suppression of Erk, NF-kB and Nrf2 survival pathways and downstream target genes (e.g. cyclin D1, SOD1, gamma-GCS), as well as up-regulation of proapoptotic signaling (e.g. p53, caspase 3). Consistent with the observed steatotic and cholestatic phenotype, nuclear receptors RAR, RXR showed increased activation while expression levels of CAR, FXR and PPAR-alpha were decreased in MetKO. Collectively, our data provide evidence for the critical involvement of c-Met signaling in cholesterol and bile acids toxicity.

    2016-03-01

    Full Text Available Accumulating evidence demonstrates that microRNA-29 (miR-29 expression is prominently decreased in patients with hepatic fibrosis, which consequently stimulates hepatic stellate cells’ (HSCs activation. We used a cDNA microarray study to gain a more comprehensive understanding of genome-wide gene expressions by adjusting miR-29a expression in a bile duct-ligation (BDL animal model. Methods: Using miR-29a transgenic mice and wild-type littermates and applying the BDL mouse model, we characterized the function of miR-29a with regard to cholestatic liver fibrosis. Pathway enrichment analysis and/or specific validation were performed for differentially expressed genes found within the comparisons. Results: Analysis of the microarray data identified a number of differentially expressed genes due to the miR-29a transgene, BDL, or both. Additional pathway enrichment analysis revealed that TGF-β signaling had a significantly differential activated pathway depending on the occurrence of miR-29a overexpression or the lack thereof. Furthermore, overexpression was found to elicit changes in Wnt/β-catenin after BDL. Conclusion: This study verified that an elevated miR-29a level could alleviate liver fibrosis caused by cholestasis. Furthermore, the protective effects of miR-29a correlate with the downregulation of TGF-β and associated with Wnt/β-catenin signal pathway following BDL.

    Full Text Available BACKGROUND AND OBJECTIVES: Cryptogenic fibrosing pleuritis is an extremely rare disease, which can affect both lungs from a very young age. The most common finding is severe lung restriction resulting in both hypoxemic and ventilatory failure. CASE REPORT: Male patient, 26 year old with acute deterioration of chronic respiratory failure. Following admission prolonged mechanical ventilation was necessary. An atypical clinical presentation made the diagnosis difficult, but eventually cryptogenic fibrosing pleuritis and lung fibrosis were established. CONCLUSIONS: The prognostic outcome of patients with the final diagnosis of cryptogenic fibrosing pleuritis is extremely poor, especially in an advanced phase of this disease. We recommend early treatment with corticosteroids or surgical pleural decortication.JUSTIFICATIVA E OBJETIVOS: Fibrose pleural idiopática é uma doença rara e pode afetar ambos pulmões já desde uma idade precoce. O achado mais comum na fibrose pleural idiopática é uma restrição pulmonar grave que pode levar a um quadro de falência respiratória e hipoxemia. RELATO DO CASO: Paciente do sexo masculino, 26 anos, internado com reagudização de insuficiência respiratória crônica e submetido à ventilação mecânica prolongada. Após intensa investigação e uma apresentação clínica atípica, foi estabelecido o diagnóstico de fibrose pleural idiopática associado à fibrose pulmonar. CONCLUSÕES: O prognóstico de pacientes com fibrose pleural idiopática é extremamente ruim, particularmente em fase avançada da doença. Recomenda-se o tratamento precoce com corticosteróides ou decorticação pleural cirúrgica.

    The Danish Committee on Adverse Drug Reactions received 1100 reports of suspected drug-induced hepatic injury during the decade 1978-1987. The causal relationship between drug and hepatic injury was classified as definite in 57 (5.2%) reports, probable in 989 (89.9%) reports, possible in 50 (4.......5%) reports and unclassifiable in four (0.4%) reports. Hepatic injuries accounted for 5.9% of all adverse drug reactions reported, and 14.7% of the lethal adverse drug reactions. A total of 47.2% were classified as acute cytotoxic, 16.2% as acute cholestatic and 26.9% as abnormal hepatic function. In 52 (4.......7%) cases the hepatic injury was lethal; only 14 (1.3%) cases were chronic. Halothane accounted for 25% of the cases. The incidence of halothane-induced hepatic injury is decreasing, and only one lethal case has been reported since 1981. Next to halothane, sulfasalazine was the drug most often suspected...

    In traditional Chinese medicine, Glechoma hederacea is frequently prescribed to patients with cholelithiasis, dropsy, abscess, diabetes, inflammation, and jaundice. Polyphenolic compounds are main bioactive components of Glechoma hederacea. This study was aimed to investigate the hepatoprotective potential of hot water extract of Glechoma hederacea against cholestatic liver injury in rats. Cholestatic liver injury was produced by ligating common bile ducts in Sprague-Dawley rats. Saline and hot water extract of Glechoma hederacea were orally administrated using gastric gavages. Liver tissues and bloods were collected and subjected to evaluation using histological, molecular, and biochemical approaches. Using a rat model of cholestasis caused by bile duct ligation (BDL), daily oral administration of Glechoma hederacea hot water extracts showed protective effects against cholestatic liver injury, as evidenced by the improvement of serum biochemicals, ductular reaction, oxidative stress, inflammation, and fibrosis. Glechoma hederacea extracts alleviated BDL-induced transforming growth factor beta-1 (TGF-β1), connective tissue growth factor, and collagen expression, and the anti-fibrotic effects were accompanied by reductions in α-smooth muscle actin-positive matrix-producing cells and Smad2/3 activity. Glechoma hederacea extracts attenuated BDL-induced inflammatory cell infiltration/accumulation, NF-κB and AP-1 activation, and inflammatory cytokine production. Further studies demonstrated an inhibitory effect of Glechoma hederacea extracts on the axis of high mobility group box-1 (HMGB1)/toll-like receptor-4 (TLR4) intracellular signaling pathways. The hepatoprotective, anti-oxidative, anti-inflammatory, and anti-fibrotic effects of Glechoma hederacea extracts seem to be multifactorial. The beneficial effects of daily Glechoma hederacea extracts supplementation were associated with anti-oxidative, anti-inflammatory, and anti-fibrotic potential, as well as down

    Cholestatic liver disease is characterized by the progressive destruction of biliary epithelial cells (BECs) followed by fibrosis, cirrhosis and liver failure. Activated hepatic stellate cells (HSCs) and portal fibroblasts are the major cellular effectors of enhanced collagen deposition in biliary fibrosis. Apamin, an 18 amino acid peptide neurotoxin found in apitoxin (bee venom), is known to block Ca2+-activated K+ channels and prevent carbon tetrachloride-induced liver fibrosis. In the present study, we aimed to ascertain whether apamin inhibits biliary fibrosis and the proliferation of HSCs. Cholestatic liver fibrosis was established in mouse models with 3,5-diethoxycarbonyl-1,4-dihydrocollidine (DDC) feeding. Cellular assays were performed on HSC-T6 cells (rat immortalized HSCs). DDC feeding led to increased hepatic damage and proinflammtory cytokine levels. Notably, apamin treatment resulted in decreased liver injury and proinflammatory cytokine levels. Moreover, apamin suppressed the deposition of collagen, proliferation of BECs and expression of fibrogenic genes in the DDC-fed mice. In HSCs, apamin suppressed activation of HSCs by inhibiting the Smad signaling pathway. These data suggest that apamin may be a potential therapeutic target in cholestatic liver disease.

    Background: Endoscopic evaluation is critical in assessing the cause of obstructive jaundice. Cytological techniques including bile aspiration and biliary brushings have become the initial diagnostic modality. Aim: The aim of this study is to evaluate the role of endoscopic biliary tract cytology as a diagnostic tool in the evaluation of extrahepatic cholestatic jaundice. Materials and Methods: A total of 56 biliary tract specimens including 34 bile aspirations and 22 biliary brushings from 41 consecutive patients who had presented with obstructive jaundice and underwent endoscopic retrograde cholangiopancreatography (ERCP) were assessed by cytological examination. The smears prepared were analyzed for standard cytological features. Results: Cytologic diagnosis was adenocarcinoma in 13 (31.7%) cases, atypical in 2 (4.9%), reactive in 3 (7.3%) and benign changes in 19 (46.3%) cases. 4 (9.8%) cases were non-diagnostic. Serum bilirubin was significantly elevated in the malignant group. Biliary stricture was the most common finding on ERCP (68.3%). On cytological examination, presence of solitary, intact atypical cells, enlarged nuclei, irregular nuclear membrane, coarse chromatin and nucleoli were important cytologic criteria for differentiating malignant from benign biliary specimens. Conclusions: Regular use of bile cytology and brushings during ERCP evaluation of extrahepatic cholestatic jaundice is invaluable in obtaining a morphologic diagnosis. A systematic approach, use of strict cytomorphologic criteria and inclusion of significant atypia as malignant diagnosis may improve the sensitivity. PMID:24130407

    Methimazole is an antithyroid drug that is widely used for the treatment of hyperthyroidism. As an inhibitor of the enzyme thyroperoxidase, methimazole is generally well-tolerated. However, there have been increasing reports of methimazole-induced liver damage, although this effect of methimazole has been limited by the absence of objective diagnosis of the liver condition or the inappropriate use of the Naranjo scale. We present the case of an elderly man with hyperthyroidism, gastritis, and epilepsy who developed liver damage after administration of multiple drugs. Considering the low sensitivity of the Naranjo scale in detecting rare reactions associated with liver damage, we used the Roussel-Uclaf Causality Assessment Method scale, with a finding of cholestatic jaundice hepatitis induced by methimazole. The patient's liver enzyme levels improved after discontinuation of methimazole. Our case underlines the possible hepatoxicity associated with the use of methimazole. A review of the literature confirmed a selective hepatoxicity risk in individuals of Asian ethnicity, which has not been identified in Caucasian or Black populations. Physicians should be aware of the risk of hepatoxicity when prescribing oral methimazole to patients of Asian ethnicity.

    A common complaint among patients with fibrositis syndrome is exhaustion and fatique. It was therefore felt desirable to evaluate the muscle strength of these patients compared with normal subjects. Maximum isometric and isokinetic strength of knee extension was measured in 15 patients and 15...... healthy matched subjects, using an isokinetic dynamometer (Cybex II). Maximum isometric strength at various knee extension angles (90 degrees, 60 degrees and 30 degrees degrees) was significantly (p less than 0.001) lower in the fibrositis group than in controls, a reduction of approximately 58......-66%. Maximum isokinetic strength at various knee extension velocities (30-240 degrees per second) was also significantly (p less than 0.01) lower in the fibrositis group than in controls, the reduction being approximately 41-51%. In conclusion, isometric and isokinetic muscle strength is found to be lower...

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

    We present CT, MRI and venography findings in 13-year boy with mediastinal fibrosis and superior vena cava (SVC) thrombosis associated with Behcet's disease. Fibrosing mediastinitis is an excessive fibrotic reaction that occurs in the mediastinum and may lead to compression of mediastinal structures (especially vascular). This condition is usually idiopathic, though many (and perhaps most) cases in the USA are thought to be caused by an abnormal immunologic response to Histoplasma capsulatum infection. SVC syndrome secondary to extrinsic compression by mediastinal fibrosis combined with Behcet's disease has rarely been described. Radiological investigations of this syndrome are necessary to avoid a useless anticoagulant therapy

    Fibrosing mediastinitis (FM) is a rare benign disease resulting from an excessive fibro-inflammatory reaction in the mediastinum that can compress and occlude mediastinal structures. There is a granulomatous and a diffuse non-granulomatous form of FM. We present a case of granulomatous FM following possible tuberculosis in a young child who presented with severe compression of the airways, pulmonary artery and the superior vena cava (SVC), unresponsive to treatment, resulting in death. Bronchoscopic findings included concentric narrowing and mucosal hyperaemia of the tracheobronchial airways. This case raises awareness of this rare complication and the limited treatment options available. © 2018 Wiley Periodicals, Inc.

    The cholestatic disorders progressive familial intrahepatic cholestasis type 1 (PFIC1, also referred to as Byler’s disease) and benign recurrent intrahepatic cholestasis type 1 (BRIC1) are caused by mutation of the P4-ATPase ATP8B1. The substrate of ATP8B1 is very likely to be phosphatidylserine...... families have been investigated, and more than 50 distinct disease mutations have been identified, with roughly half being missense mutations. In this project we try to answer the question whether PFIC1 mutations are generally more disturbing than BRIC1 mutations with respect to expression, structural...... stability and function. We investigate the mutations in our well functioning system of ATP8A2, being expressed in mammalian HEK293T cells, affinity-purified, and reconstituted in lipid vesicles.

    2014-01-01

    Aim: To investigate the feasibility of gadoxetate disodium-enhanced magnetic resonance (MR) cholangiography in chronic obstructive cholestatic biliary disease in the clinical setting. Materials and methods: Twenty-three patients with dilated bile duct trees and ten volunteers underwent gadoxetate disodium-enhanced liver MR cholangiography and were enrolled in the present retrospective study. Gadoxetate disodium was given in a standardized manner as a bolus injection at a dose of 0.25 mmol/kg of body weight (0.1 ml/kg). Region of interest-based measurement of mean enhancement of the dilated bile ducts was performed in series before gadoxetate disodium administration and during hepatobiliary phases. Results: Direct comparison of mean bile duct enhancement during hepatobiliary phases in the clinical imaging window between healthy volunteers [4.7 ± 2.2 arbitrary units (au)] and patients with dilated bile ducts (0.1 ± 0.3 au) revealed significantly lower or absent enhancement in dilated bile ducts (p = 0.001). Conclusion: Standard clinical gadoxetate disodium-enhanced MR cholangiography is not a reliable technique for the evaluation of the biliary trees, because of altered biliary gadoxetate disodium elimination in patients with chronic obstructive biliary diseases. - Highlights: • Biliary excretion of gadoxetic disodium is impaired in subjects with chronic central or segmental bile duct obstruction. • MR cholangiography using gadoxetic disodium is not feasible in patients with chronic cholestatic bile duct disease. • Gadoxetic disodium enhanced MRI is a potential biomarker to measure hepatobiliary transporter function

  8. Diagnostic and therapeutic approach to cholestatic liver disease Abordaje diagnóstico y terapéutico del síndrome colestásico

    Directory of Open Access Journals (Sweden)

    T. Pérez Fernández

    2004-01-01

    Full Text Available When cholestatic liver disease is present, liver ultrasound should be performed to ascertain if cholestasis is extrahepatic or intrahepatiic. If bile ducts appear dilated and the probability of interventional treatment is high, endoscopic retrograde cholagio-pancreatography (ERCP or trans-hepatic cholangiography (THC should be the next step. If the probability of interventional therapeutics is low, cholangio-MRI should be performed. Once bile duct dilation and space occupying lesions are excluded, a work up for intrahepatic cholestasis should be started. Some especific clinical situations may be helpful in the diagnostic strategy. If cholestasis occurs in the elderly, drug-induced cholestatic disease should be suspected, whereas if it occurs in young people with risk factors, cholestatic viral hepatitis is the most likely diagnosis. During the first trimester of pregnancy cholestasis may occur in hiperemesis gravidorum, and in the third trimester of gestation cholestasis of pregnancy should be suspected. A familial history of recurrent cholestasis points to benign recurrent intrahepatic cholestasis. The occurrence of intrahepatic cholestasis in a mid-dle-aged woman is a frequent presentation of primary biliary cirrhosis, whereas primary sclerosing cholangitis should be suspected in young males with inflammatory bowel disease. The presence of vascular spider nevi, ascites, and a history of alcohol abuse should point to alcoholic hepatitis. Neonatal cholestasis syndromes include CMV, toxoplasma and rubinfections or metabolic defects such as cystic fibrosis, α1-antitripsin deficiency, bile acid synthesis defects, or biliary atresia. The treatment of cholestasis should include a management of complications such as pruritus, osteopenia and correction of fat soluble vitamin deficiencies. When hepatocellular failure or portal hypertension-related complications occur, liver transplantation should be considered.Ante la presencia de colestasis, se debe

    2008-10-01

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

    Fellegara, Giovanni; Rosai, Juan

    2015-03-01

    During the course of our consultation activity, we have recognized a peculiar form of thyroiditis in which multiple foci of fibrosis, most of which were associated with reactive atypia of the surrounding follicles, are present. We have referred to this condition, both in our consultation reports and in the third series of A.F.I.P. Fascicle on Tumors of the Thyroid Gland, as "multifocal fibrosing thyroiditis" or (less frequently) "multifocal sclerosing thyroiditis," which are descriptive terms that highlight the benign/inflammatory nature of the process, its multiplicity, and its unknown pathogenesis. The aim of this study is to better define the morphologic features of this process and correlate it with some clinical data. With this purpose, the consultation files of one of the authors (J.R.) were searched for cases coded as multifocal fibrosing thyroiditis or multifocal sclerosing thyroiditis in a 20-year period ranging from January 1989 to December 2009. A total of 55 cases were identified that displayed the above-listed features. There were 51 (93%) female and 4 (7%) male patients (F/M=12.75), with ages ranging between 15 and 71 years (mean age, 47.03 y; median age, 44.5 y). Microscopically, multiple foci of fibrosis were identified in all cases, their number ranging from 2 to 51 per case (mean number, 16), with a mean diameter of 3 mm (range: 0.36 to 15.1 mm). Although heterogenous in shape and size, the individual foci were rather similar to each other in composition, being characterized by a fibrotic poorly cellular center that merged with a cellular peripheral zone. Some of the follicular structures present at the periphery of the scar and-to a lesser extent-those entrapped inside it underwent complex reactive and regenerative (atypical) changes that simulated malignancy. We discuss the differential diagnosis with other benign and malignant thyroid conditions and speculate about its pathogenesis and possible relationship with papillary thyroid microcarcinoma.

    24-nor-ursodeoxycholic acid (norUDCA) is a side-chain shortened derivate of ursodeoxycholic acid (UDCA). Since norUDCA is only ineffectively conjugated with glycine or taurine, it has specific physicochemical and therapeutic properties distinct from UDCA. Nonamidated norUDCA undergoes cholehepatic shunting enabling 'ductular targeting' and inducing a bicarbonate-rich hypercholeresis, with cholangioprotective effects. At the same time it has direct anti-inflammatory, antilipotoxic, anti fibrotic, and antiproliferative properties targeting various liver cell populations. norUDCA appears to be one of the most promising novel treatment approaches targeting the liver and the bile duct system at multifactorial and multicellular levels. This review article is a summary of a lecture given at the XXIII International Bile Acid Meeting (Falk Symposium 194) on 'Bile Acids as Signal Integrators and Metabolic Modulators' held in Freiburg, October 8-9, 2014, and summarizes the recent progress with norUDCA as a novel therapeutic approach in cholestatic and metabolic (liver) disorders. 2015 S.

    Full Text Available Background and Objectives: Accumulation of toxic bile salts in a bile duct ligation (BDL animal model plays a pivotal role in the induction of liver fibrosis. Vitamin B5 is an essential nutrient, which acts as a cofactor in many detoxification system enzymes. In the present research, the antifibrotic effect of vitamin B5 was investigated on liver cholestasis induced by BDL in rats. Methods: In this experimental study, 72 male Wistar rats were divided into 9 groups: Control, sham-operated, vitamin B5 (5, 50, and 100mg/kg bw, BDL, and BDL+vitamin B5 (5, 50, and 100mg/kg bw. After BDL, rats were given vitamin B5 via intragastric gavage for 28 consecutive days. At the end of the experiment, blood was collected from heart and activity of aspartate aminotransferase (AST, alanine aminotransferase (ALT, and alkaline phosphatase (ALP enzymes, were measured. The data were analyzed using one-way ANOVA test. Results: In the BDL animals, the serum activities of AST, ALT, and ALP significantly increased (p<0.001. Treatment of BDL rats with vitamin B5 significantly attenuated these changes. Conclusion: The results of this study indicated that vitamin B5 has hepatoprotective and antifibrotic effects in the cholestatic liver, which is likely due to the antioxidative and free radical scavenging effects of this vitamin.

    Full Text Available Bone marrow cells (BMC migrate to the injured liver after transplantation, contributing to regeneration through multiple pathways, but mechanisms involved are unclear. This work aimed to study BMC migration, characterize cytokine profile, cell populations and proliferation in mice with liver fibrosis transplanted with GFP+ BMC. Confocal microscopy analysis showed GFP+ BMC near regions expressing HGF and SDF-1 in the fibrotic liver. Impaired liver cell proliferation in fibrotic groups was restored after BMC transplantation. Regarding total cell populations, there was a significant reduction in CD68+ cells and increased Ly6G+ cells in transplanted fibrotic group. BMC contributed to the total populations of CD144, CD11b and Ly6G cells in the fibrotic liver, related to an increment of anti-fibrotic cytokines (IL-10, IL-13, IFN-γ and HGF and reduction of pro-inflammatory cytokines (IL-17A and IL-6. Therefore, HGF and SDF-1 may represent important chemoattractants for transplanted BMC in the injured liver, where these cells can give rise to populations of extrahepatic macrophages, neutrophils and endothelial progenitor cells that can interact synergistically with other liver cells towards the modulation of an anti-fibrotic cytokine profile promoting the onset of liver regeneration.

    We report a complicated case of cholestatic hepatitis with suspected autoimmune hemolytic anemia (AIHA) and copper toxicity syndrome after HSCT and donor lymphocyte infusion (DLI). A 19-year-1-month-old girl presented with a history of CML. She underwent matched unrelated donor HSCT and donor lymphocyte infusion subsequently. Three months later, yellowish discoloration of the skin was found, which was accompanied by progressive itchy skin, easy fatigability, insomnia, and dark urine output. After admission, liver function disorders were observed. Methylprednisolone was administered for suspected hepatic GVHD. Although abdominal sonography revealed no evidence of biliary tract obstruction and the viral hepatitis survey disclosed unremarkable findings; silymarin and ursodeoxycholic acid were administered to preserve the liver function. In addition, rituximab was prescribed for suspected AIHA. Because hyperbilirubinemia was progressive, mycophenolate and high-dose intravenous immunoglobulin were accordingly administered. As drug-induced liver injury cannot be excluded, all potential unconfirmed causes of drug-related hepatoxicity were discontinued. In this case, the patient's history of shrimps and chocolate consumption led us to strongly suspect cholestatic hepatitis associated with copper toxicity syndrome. High 24-hour urine copper excretion and low serum zinc levels were also confirmed. Accordingly, D-penicillamine and zinc gluconate were administered. She succumbed to progressive hepatic failure and eventual multisystem organ failure 14 months after HSCT. No autopsy was performed. This report described the combined effects of hepatic GVHD, AIHA, drugs, and copper toxicity on liver damage, and demonstrated the potential diagnostic challenges and treatment dilemmas associated with this disease.

  1. Lipid peroxidation and antioxidant enzymes activity in Plasmodium vivax malaria patients evolving with cholestatic jaundice

    Science.gov (United States)

    2013-01-01

    Background Plasmodium vivax infection has been considered a benign and self-limiting disease, however, recent studies highlight the association between vivax malaria and life-threatening manifestations. Increase in reactive oxygen species has already been described in vivax malaria, as a result of the increased metabolic rate triggered by the multiplying parasite, and large quantities of toxic redox-active byproducts generated. The present study aimed to study the oxidative stress responses in patients infected with P. vivax, who developed jaundice (hyperbilirubinaemia) in the course of the disease, a common clinical complication related to this species. Methods An evaluation of the lipid peroxidation and antioxidant enzymes profile was performed in 28 healthy individuals and compared with P. vivax infected patients with jaundice, i.e., bilirubin jaundice (34 patients), on day 1 (D1) and day 14 (D14) after anti-malarial therapy. Results Hyperbilirubinaemia was more frequent among women and patients experiencing their first malarial infection, and lower haemoglobin and higher lactate dehydrogenase levels were observed in this group. Malondialdehyde levels and activity of celuroplasmin and glutathione reductase were increased in the plasma from patients with P. vivax with jaundice compared to the control group on D1. However, the activity of thioredoxin reductase was decreased. The enzymes glutathione reductase, thioredoxin reductase, thiols and malondialdehyde also differed between jaundiced versus non-jaundiced patients. On D14 jaundice and parasitaemia had resolved and oxidative stress biomarkers were very similar to the control group. Conclusion Cholestatic hyperbilirubinaemia in vivax malaria cannot be totally disassociated from malaria-related haemolysis. However, significant increase of lipid peroxidation markers and changes in antioxidant enzymes in patients with P. vivax-related jaundice was observed. These results suggest oxidative processes contributing

    Stool colour assessment is a screening method for biliary tract obstruction in infants. This study is aimed to be a proof of concept work of digital photograph image analysis of stool colour compared to colour grading by a colour card, and the stool bilirubin level test. The total bilirubin (TB) level contents in stool samples from 17 infants aged less than 1 year, seven with confirmed cholestatic jaundice and ten healthy subjects was measured, and outcome correlated with the physical colour of the stool. The seven infants with cholestasis included 6 cases of biliary atresia and 1 case of pancreatic mass. All pre-operative stool samples in these cases were indicated as grade 1 on the stool card (stool colour in healthy infants ranges from 4 to 6). The average stool TB in the pale stool group was 43.07 μg/g compared to 101.78 μg/g in the non-pale stool group. Of the 3 colour channels assessed in the digital photographs, the blue and green light were best able to discriminate accurately between the pre-operative stool samples from infants with cholestasis and the samples from the healthy controls. With red, green, and blue (RGB) image analysis using wave level as the ANN input, the system predicts the stool TB with a relationship coefficient of 0.96, compared to 0.61 when stool colour card grading was used. Input from digital camera images of stool had a higher predictive capability compared to the standard stool colour card, indicating using digital photographs may be a useful tool for detection of cholestasis in infants.

    Osteoporosis is a major complication of chronic cholestatic liver disease (CCLD). We evaluated the efficacy of using disodium pamidronate (1.0 mg/kg body weight) for the prevention (Pr) or treatment (Tr) of cholestasis-induced osteoporosis in male Wistar rats: sham-operated (Sham = 12); bile duct-ligated (Bi = 15); bile duct-ligated animals previously treated with pamidronate before and 1 month after surgery (Pr = 9); bile duct-ligated animals treated with pamidronate 1 month after surgery (Tr = 9). Rats were sacrificed 8 weeks after surgery. Immunohistochemical expression of IGF-I and GH receptor was determined in the proximal growth plate cartilage of the left tibia. Histomorphometric analysis was performed in the right tibia and the right femur was used for biomechanical analysis. Bone material volume over tissue volume (BV/TV) was significantly affected by CCLD (Sham = 18.1 ± 3.2 vs Bi = 10.6 ± 2.2%) and pamidronate successfully increased bone volume. However, pamidronate administered in a preventive regimen presented no additional benefit on bone volume compared to secondary treatment (BV/TV: Pr = 39.4 ± 12.0; Tr = 41.2 ± 12.7%). Moreover, the force on the momentum of fracture was significantly reduced in Pr rats (Sham = 116.6 ± 23.0; Bi = 94.6 ± 33.8; Pr = 82.9 ± 22.8; Tr = 92.5 ± 29.5 N; P < 0.05, Sham vs Pr). Thus, CCLD had a significant impact on bone histomorphometric parameters and pamidronate was highly effective in increasing bone mass in CCLD; however, preventive therapy with pamidronate has no advantage regarding bone fragility

    Oleanolic acid (OA) is a triterpenoids that exists widely in plants. OA is effective in protecting against hepatotoxicants. Whereas a low dose of OA is hepatoprotective, higher doses and longer-term use of OA produce liver injury. This study characterized OA-induced liver injury in mice. Adult C57BL/6 mice were given OA at doses of 0, 22.5, 45, 90, and 135 mg/kg, s.c., daily for 5 days, and liver injury was observed at doses of 90 mg/kg and above, as evidenced by increases in serum activities of alanine aminotransferase and alkaline phosphatase, increases in serum total bilirubin, as well as by liver histopathology. OA-induced cholestatic liver injury was further evidenced by marked increases of both unconjugated and conjugated bile acids (BAs) in serum. Gene and protein expression analysis suggested that livers of OA-treated mice had adaptive responses to prevent BA accumulation by suppressing BA biosynthetic enzyme genes (Cyp7a1, 8b1, 27a1, and 7b1); lowering BA uptake transporters (Ntcp and Oatp1b2); and increasing a BA efflux transporter (Ostβ). OA increased the expression of Nrf2 and its target gene, Nqo1, but decreased the expression of AhR, CAR and PPARα along with their target genes, Cyp1a2, Cyp2b10 and Cyp4a10. OA had minimal effects on PXR and Cyp3a11. Taken together, the present study characterized OA-induced liver injury, which is associated with altered BA homeostasis, and alerts its toxicity potential. - Highlights: • Oleanolic acid at higher doses and long-term use may produce liver injury. • Oleanolic acid increased serum ALT, ALP, bilirubin and bile acid concentrations. • OA produced feathery degeneration, inflammation and cell death in the liver. • OA altered bile acid homeostasis, affecting bile acid synthesis and transport.

Caracteriza-se por mutações na CFTR, uma proteína transmembranar responsável pelo transporte de cloretos. Esta proteína tem uma ampla distribuição epitelial, o que dá um carácter sistémico a esta doença e consequentemente múltiplas manifestações clínicas de gravidade variável. A melhoria dos cuidados de saúde, associada ao desenvolvimento do arsenal terapêutico, permitiu um aumento da sobrevida destes doentes, de tal forma que a FQ já não pode ser abordada como doença da idade pediátrica.

Abstract: Cystic Fibrosis (CF is the recessive autossomic disease more frequent in the caucasian race. The main characteristic is a mutation in CFTR, a trans-membranar protein, responsible for chlorates transportation. This protein has a diffuse epithelial distribution, which gives a multissistemic involvement to this disease, with clinical manifestations with variable degrees of severity. The development of better health care associated with new therapeutic options became responsible for an increase of survival, so CF is no longer a paediatric disease. Lung transplantation also has an important role, bringing new treatment perspectives.So, this pathology has an increased multi-disciplinary involvement in which the pulmonologist have a preponderant role.

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

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

    Our objective was to evaluate the associated CT features and physiological consequences of traction bronchiectasis in patients with cryptogenic fibrosing alveolitis (CFA). The CT scans of 212 patients with CFA (158 men, 54 women; mean age 62.2±10.6 years) were evaluated independently by two observers. The extent of fibrosis, the proportions of a reticular pattern and ground-glass opacification and the extent of emphysema were scored at five levels. The predominant CT pattern, coarseness of a reticular pattern and severity of traction bronchiectasis were graded semiquantitatively. Physiological indices were correlated with CT features. There was traction bronchiectasis on CT in 202 of 212 (95%) patients. Increasingly severe traction bronchiectasis was independently associated with increasingly extensive CFA (p CO (p 2 (p<0.0005), but not indices of air-flow obstruction. In CFA, traction bronchiectasis increases with more extensive disease, a lower proportion of ground-glass opacification and a coarser reticular pattern, but it decreases with concurrent emphysema. Increasingly severe traction bronchiectasis is associated with additional physiological impairment for a given extent of pulmonary fibrosis and emphysema. (orig.)

    Multifocal fibrosing thyroiditis (MFT) is characterized by numerous foci of fibrosis in a stellate configuration with fibroelastotic and fibroblastic centers entrapping epithelial structures. MFT has been proposed as a risk factor for papillary thyroid carcinoma (PTC) development. We attempted to identify whether MFT showed such molecular changes and could possibly be related to PTC. We identified seven cases of PTC with MFT in our institutional pathology database and personal consult service of one of the authors (VAL) for the years 1999 to 2012. Areas of PTC, MFT, and normal tissue were selected for BRAF analysis. Macro-dissection, DNA extraction and PCR amplification, and pyrosequencing were performed to detect BRAF mutations in codon 600. All of the MFT lesions and normal thyroid tissue were negative for BRAF mutations. Of the seven PTCs analyzed, five (71 %) were negative for BRAF mutations, while two cases were positive. In our study, none of the MFT lesions harbored BRAF mutations, whereas 29 % (two of seven) PTCs in the same gland were positive. Hence, in this small study, we found no evidence that the MFT lesion is a direct precursor to PTC. It is likely an incidental bystander in the process and a reflection of the background thyroiditis.

  18. Histopathologic Overlap between Fibrosing Mediastinitis and IgG4-Related Disease

    Tobias Peikert

    2012-01-01

    Full Text Available Fibrosing mediastinitis (FM and IgG4-related disease (IgG4-RD are two fibroinflammatory disorders with potentially overlapping clinical and radiological features. In this paper, we looked for histopathologic features of IgG4-RD and enumerated infiltrating IgG4-positive plasma cells within mediastinal tissue biopsies from FM patients. We identified 15 consecutive FM surgical mediastinal tissue biopsies between 1985 and 2006. All patients satisfied the clinical and radiological diagnostic criteria for FM. All patients had either serological or radiological evidence of prior histoplasmosis or granulomatous disease, respectively. Formalin-fixed paraffin-embedded tissue sections of all patients were stained for H&E, IgG, and IgG4. Three samples met the predefined diagnostic criteria for IgG4-RD. In addition, characteristic histopathologic changes of IgG4-RD in the absence of diagnostic numbers of tissue infiltrating IgG4-positive plasma cells were seen in a number of additional cases (storiform cell-rich fibrosis in 11 cases, lymphoplasmacytic infiltrate in 7 cases, and obliterative phlebitis/arteritis in 2 cases. We conclude that up to one-third of histoplasmosis or granulomatous-disease-associated FM cases demonstrate histopathological features of IgG4-RD spectrum. Whether these changes occur as the host immune response against Histoplasma or represent a manifestation of IgG4-RD remains to be determined. Studies to prospectively identify these cases and evaluate their therapeutic responses to glucocorticoids and/or other immunosuppressive agents such as rituximab are warranted.

    Primitive lung cancers developed on lung fibroses are both diagnostic and therapeutic challenges. Their incidence may increase with new more efficient lung fibrosis treatments. Our aim was to describe a cohort of lung cancers associated with idiopathic pulmonary fibrosis (IPF) and other lung fibrotic disorders (non-IPF), and to characterize their molecular alterations using immunohistochemistry and next-generation sequencing (NGS). Thirty-one cancer samples were collected from 2001 to 2016 in two French reference centers for pulmonary fibrosis - 18 for IPF group and 13 for non-IPF group. NGS was performed using an ampliseq panel to analyze hotspots and targeted regions in 22 cancer-associated genes. ALK, ROS1 and PD-L1 expressions were assessed by immunohistochemistry. Squamous cell carcinoma was the most frequent histologic subtype in the IPF group (44%), adenocarcinoma was the most frequent subtype in the non-IPF group (62%). Forty-one mutations in 13 genes and one EGFR amplification were identified in 25 samples. Two samples had no mutation in the selected panel. Mutations were identified in TP53 (n = 20), MET (n = 4), BRAF (n = 3), FGFR3, PIK3CA, PTEN, STK11 (n = 2), SMAD4, CTNNB1, DDR2, ERBB4, FBXW7 and KRAS (n = 1) genes. No ALK and ROS1 expressions were identified. PD-L1 was expressed in 10 cases (62%) with only one (6%) case >50%. This extensive characterization of lung fibrosis-associated cancers evidenced molecular alterations which could represent either potential therapeutic targets either clues to the pathophysiology of these particular tumors. These findings support the relevance of large molecular characterization of every lung fibrosis-associated cancer.

    Hashimoto thyroiditis (HT) and the fibrosing variant of Hashimoto thyroiditis (FVHT) are immune-mediated tumefactive lesions of the thyroid. Immunoglobulin G4-related disease (IgG4-RD) is now a widely recognised multi-organ system disease characterised by elevated serum and tissue concentrations of IgG4. In this study, the authors address several unresolved questions pertaining to the relationship between HT and FVHT, and the association of each of these diseases with IgG4-RD. The authors evaluated 28 consecutive cases of HT and nine cases of FVHT. The clinical, demographic and serological data were recorded. The slides were stained immunohistochemically using antibodies to IgG4 and IgG and the quantitative analysis was recorded. Data on thyroid function tests were available on seven cases of FVHT and 14 cases of HT. Based on the availability of data, hypothyroidism was noted in 62% (9/14) of HT and 86% of FVHT (6/7). FVHT demonstrated an exaggerated lobular pattern with lobules separated by cellular storiform-type fibrosis, resembling fibrosis seen in other forms of IgG-RD. The median IgG4 counts per high power field (×40) in HT and FVHT were 2.3 and 22, respectively. The median IgG4:IgG ratios in HT and FVHT were 0.11 and 0.58, respectively. The authors propose that FVHT belongs to the spectrum of IgG4-RD. Although a proportion of cases of HT show elevated numbers of IgG4 positive plasma cells, these cases lack the histological features typically associated with IgG4-RD, and thus the relationship between HT and IgG4-RD remains unproven.

    Full Text Available A fibrose hepática causada por obstrução do ducto biliar induz alterações tanto na estrutura como na função do fígado, e pode levar a cirrose e insuficiência hepática, quando não tradada. A membrana amniótica humana (MA devido às suas propriedades anti-inflamatórias e anti-fibróticas pode ser uma terapia alternativa. A proposta desse trabalho é analisar as alterações nos níveis séricos das principais enzimas celulares e da albumina, na fibrose hepática induzida pela ligadura do ducto biliar (LDB e após o tratamento com a MA. Dez ratos foram divididos nos grupos LDB e LDB+MA, e eutanasiados após 9 semanas da LDB. As amostras de sangue foram processadas bioquimicamente para análise da albumina (ALB, fosfatase alcalina (FA e transaminases (TGP e TGO.  Comparando os grupos experimentais verificou-se que no grupo LDB+MA houve a diminuição da ALB e TGP e no grupo LDB houve a diminuição da FA e TGO, entretanto sem apresentar diferença significante entre os grupos. Conclui-se que a MA, quando aplicada ao fígado no mesmo momento da indução da fibrose, parece não ter exercido efeito significativo na função hepática.

    Full Text Available Resumo: Descreve-se o caso clínico de um doente do sexo masculino com uma massa mediastínica de crescimento lento. Após terem-se efectuado vários exames complementares, foi através de cirurgia que se confirmou o diagnóstico de fibrose idiopática do mediastino. A remoção parcial da massa permitiu uma estabilização transitória das suas dimensões. Cerca de quatro anos depois, verificou-se um crescimento marcado com repercurssões importantes, através da inevitável compressão de estruturas vitais, que conduziram a hipertensão pulmonar grave. A fibrose idiopática do mediastino é uma entidade extremamente rara, estando descritas associações a outras patologias, mais frequentemente às auto-imunes, mas apresenta sempre um curso fatal quando não é possível a cirurgia.Rev Port Pneumol 2005; XI (2: 155-163 Abstract: We herein report a case of a male patient, who presented a mediastinal mass that had a slow growth over the years. After surgery, that made the diagnosis of idiopathic mediastinal fibrosis, the growth stabilized. Four years latter it was observed a substantial increase which lead to the inevitable compression of vital structures which, in turn, led to pulmonary hypertension. Idiopathic mediastinal fibrosis is an extremely rare pathology. There are same cases in which it is associated with other pathologies but has always a fatal prognosis when surgery is not an option.Rev Port Pneumol 2005; XI (2: 155-163 Palavras-chave: Fibrose do mediastino, síndroma da veia cava superior, hipertensão pulmonar, mediastinite fibrosante, Key words: Mediastinal fibrosis, superior vena cava syndrome, pulmonary hypertension, fibrosis mediastinites

Ecocardiograma: canal átrio-ventricular total, hipertensão pulmonar, persistência do canal arterial. Sorologias negativas. Biópsia hepática: colestase, fibrose portal e sinusoidal, elementos mielóides imaturos. Após normalização da leucometria, manteve plaquetopenia e disfunção hepática. No 50º dia de vida, quimioterapia com Daunoblastina e Citarabina. Evoluiu com pneumonia e insuficiência renal. Óbito no 61ºdia. Comentários: A história natural da SMT gera questões intrigantes a respeito de sua origem, evolução e desenvolvimento de leucemia subseqüente. A disfunção hepática e a fibrose têm impacto prognóstico. Em relato anterior, de cada oito casos de SMT com disfunção hepática, seis evoluíram para óbito, sendo que fibrose hepática difusa, associada a eritropoese extra-medular, foi encontrada em quatro casos. Acredita-se que a lesão hepática resulta da produção de citocinas pelos megacariócitos, por ser o fígado o segundo órgão hematopoético de células anormais, após a medula óssea.

    Terbinafine is a commonly prescribed antifungal agent used in the treatment of trichophytic onychomycosis and chronic cutaneous mycosis that are resistant to other treatments. This case report highlights a rarely documented but important adverse hepatic reaction that was caused by the use of oral terbinafine. A woman in her thirties presented with a 3-week history of jaundice, malaise, itching, nausea, decreased appetite, weight loss, dark orange urine and intermittent non-radiating epigastric pain. She had recently finished a 3-week course of oral terbinafine for a fungal nail infection. Liver biopsy findings were consistent with chronic active hepatitis secondary to a drug reaction. A few days after initial presentation, the patient developed erythema nodosum. Delayed development of erythema nodosum secondary to terbinafine could not be excluded. 2014 BMJ Publishing Group Ltd.

    Predictions of the absorption, distribution, metabolism, excretion, and toxicity of compounds in pharmaceutical development are essential aspects of the drug discovery process. B-CLEAR is an in vitro system that uses sandwich-cultured hepatocytes to evaluate and predict in vivo hepatobiliary disposition (hepatic uptake, biliary excretion, and biliary clearance), transporter-based hepatic drug-drug interactions, and potential drug-induced hepatotoxicity. Automation of predictive technologies is an advantageous and preferred format in drug discovery. In this study, manual and automated studies are investigated and equivalence is demonstrated. In addition, automated applications using model probe substrates and inhibitors to assess the cholestatic potential of drugs and evaluate hepatic drug transport are examined. The successful automation of this technology provides a more reproducible and less labor-intensive approach, reducing potential operator error in complex studies and facilitating technology transfer.

    Full Text Available Introduction . Frontal fibrosing alopecia is a primary lymphocytic cicatricial alopecia with progressive frontotemporal hairline recession. In some cases, hair loss in the mid-frontal scalp, similar to female pattern hair loss, may be observed. Objective. Assessment of the trichoscopic pattern of mid-frontal scalp hair loss in patients diagnosed with frontal fibrosing alopecia. Material and methods. The retrospective analysis included 31 women diagnosed with frontal fibrosing alopecia and hair loss in the mid-frontal scalp and 36 women diagnosed with female pattern hair loss. Results . In patients with frontal fibrosing alopecia two different trichoscopic patterns in the mid-frontal scalp were identified. In 68% of patients (21/31 we observed a diffuse fibrotic pattern. It was characterized by irregular arrangement of follicular units with small areas with loss of follicular units, an increased percentage of follicular units with one hair and a decreased percentage of follicular units with three hairs, normal hair shaft thickness and presence of mild perifollicular scaling. The androgenetic alopecia pattern was present in 32% of patients (10/31. It was characterized by hair shaft thickness diversity (20% or more, a percentage of vellus hairs higher than 10%, presence of yellow dots, an increased percentage of follicular units with one hair and a decreased percentage of follicular units with three hairs. Conclusions. In patients with frontal fibrosing alopecia and coexisting mid-frontal scalp hair loss, we identified two different patterns of this area in trichoscopy: the diffuse fibrotic pattern (more common and the androgenetic alopecia pattern. This observation may have therapeutic and prognostic implications.

    2016-01-01

    This case describes a young non-pregnant cat that presented with uterine prolapse in association with an unusual diffuse, polypoid, fibrosing perimetritis and parametritis. Following ovariohysterectomy the cat recovered fully. No intra-abdominal complications were seen on ultrasound examination 3 months postsurgery. At the time of writing, the cat remains healthy. Uterine prolapse in the cat is relatively rare and usually associated with the periparturient period. Inflammatory polypoid perimetritis and parametritis have not previously been documented in cats, and in dogs have only been reported in association with the administration of oestrogenic compounds. The polypoid inflammation affecting the uterus and parametrium may have contributed to increased laxity of the uterine ligaments and predisposed to the development of uterine prolapse.

  5. Recurrent Pneumonia due to Fibrosing Mediastinitis in a Teenage Girl: A Case Report with Long-Term Follow-Up

    Directory of Open Access Journals (Sweden)

    Avigdor Hevroni

    2018-01-01

    Full Text Available A teenage girl was evaluated for recurrent right pneumonia. The evaluation revealed a calcified mediastinal mass that compressed the right intermediate and middle lobar bronchi, as well as the right pulmonary artery and veins. The clinical picture together with imaging studies and borderline positive serology testing suggested a diagnosis of fibrosing mediastinitis associated with histoplasmosis. This rare condition is characterized by the local proliferation of invasive fibrous tissue within the mediastinum due to a hyperimmune reaction to Histoplasma capsulatum. Antifungal and anti-inflammatory therapies are usually ineffective, and surgical intervention contains a high morbidity risk. Palliative surgery and stenting of the compressed airway have been suggested. In the past, the prognosis was thought to be poor, but recent studies demonstrate a more positive outcome. Our patient had been radiologically and functionally stable under follow-up for over thirteen years and has married and delivered two healthy children, both following an uneventful pregnancy.

    Full Text Available ObjectiveTo observe the effect of ursodeoxycholic acid (UDCA on bile secretion in patients with cholestatic liver disease of various causes. MethodsA total of 48 patients who underwent endoscopic nasobiliary drainage (ENBD in Beijing You′an Hospital Affiliated to Capital Medical University from July 2013 to May 2014 were enrolled and divided into UDCA treatment group (n=36 and control group (n=12. The patients in the UDCA group were further divided into common bile duct stone group (n=9, cholangiocarcinoma group (n=7, sclerosing cholangitis group (n=7, and post-liver transplantation group (n=13. The patients in the UDCA treatment group received oral UDCA capsules (250 mg, 3 times/day since the second day after surgery, and the daily volume of bile drainage was recorded for 7 days after surgery. Serum levels of total bilirubin (TBil, total bile acid (TBA, gamma-glutamyl transpeptidase (GGT, and alkaline phosphatase (ALP were measured on the day before surgery and the 7th day after surgery, and the effects of UDCA on volume of bile drainage, TBil, TBA, GGT, and ALP were compared between groups. The t-test was applied for comparison between groups, comparison of continuous data between these groups was made by analysis of variance; the chi-square test was applied for comparison of categorical data between groups. ResultsCompared with the control group, the UDCA treatment group had a significantly increased volume of bile drainage on the 3rd, 4th, and 5th days after surgery (t=2.461, 3.896, and 2.760; P=0.048, 0.021, and 0.034, and the increase in volume of bile drainage was more significant in the common bile duct stone group, the cholangiocarcinoma group, and the post-liver transplantation group, with peak values appearing on the 4th day after surgery. The patients in the common bile duct stone group and the post-liver transplantation group had significantly lower serum levels of TBil, GGT, and ALP on the 7th day after surgery (t=3.340, 2

    A 70-year-old lung transplant recipient patient was admitted with fever, nausea, abdominal pain, peripheral edema and pronounced weakness. An initial work-up for presumed infection revealed cholestatic hepatitis, leukocytosis and thrombocytopenia, but failed to detect a pathogen. An increased glucose uptake exclusively in the liver was demonstrated by positron emission tomography. Liver biopsy showed basophilic inclusions in the cytoplasm of hepatocytes. Broad- range 16S rRNA gene PCR followed by sequence analysis yielded Spiroplasma sp. in two independent blood samples and the liver biopsy, confirming Spiroplasma sp. as the causative agent. Antibiotic treatment with doxycycline and azithromycin led to complete recovery. © Copyright 2015 The American Society of Transplantation and the American Society of Transplant Surgeons.

Outros 6 animais foram submetidos à intervenção simulada e considerados grupo controle (IS. Todos animais foram submetidos à avaliação morfométrica do fígado, análise bioquímica do sangue e microbiológica da bile, estudo da função mitocondrial hepática e verificação do peso úmido do fígado e do baço. Na análise estatística adotou-se o nível de significância de 5%. Houve aumento significativo do peso estimado, em g/Kg de peso corporal, dos ductos biliares, da fibrose e dos hepatócitos nos animais do grupo OB (medianas de 1,30; 10,03 e 37,0 em relação aos animais controles (IS (medianas de 0,03; zero e 29,37. Após tratamento, ocorreu regressão significativa do peso estimado dos ductos biliares e da fibrose, com valores medianos de 0,22 e 0,22 para o grupo DBD, 0,45 e 3,31 para o grupo DBJ5 e 0,22 e 5,0 para o grupo DBJ15. Houve regressão significativa do peso estimado dos hepatócitos apenas nos grupos derivados com o jejuno, com valores medianos de 31,93; 24,46 e 28,52. Ocorreu aumento significativo do peso úmido do fígado e do baço no grupo OB (medianas em g/Kg de peso corporal de 49,85 e 5,71 em relação ao grupo IS (30,0 e 3,04. Houve regress

  18. Autoimmune hepatitis in a teenage boy: 'overlap' or 'outlier' syndrome--dilemma for internists.

    Science.gov (United States)

    Talukdar, Arunansu; Khanra, Dibbendhu; Mukherjee, Kabita; Saha, Manjari

    2013-02-08

    An 18-year-old boy presented with upper gastrointestinal bleeding and jaundice. Investigations revealed coarse hepatomegaly, splenomegaly and advanced oesophageal varices. Blood reports showed marked rise of alkaline phosphatase and more than twofold rise of transaminases and IgG. Liver histology was suggestive of piecemeal necrosis, interphase hepatitis and bile duct proliferation. Antinuclear antibody was positive in high titre along with positive antismooth muscle antibody and antimitochondrial antibody. The patient was positive for human leukocyte antigen DR3 type. Although an 'overlap' syndrome exists between autoimmune hepatitis (AIH) and primary biliary cirrhosis (PBC), a cholestatic variant of AIH, a rare 'outlier' syndrome could not be excluded in our case. Moreover, 'the chicken or the egg', AIH or PBC, the dilemma for the internists continued. The patient was put on steroid and ursodeoxycholic acid with unsatisfactory response. The existing international criteria for diagnosis of AIH are not generous enough to accommodate its variant forms.

  1. Diabetes melito: uma importante co-morbidade da fibrose cística Diabetes mellitus in patients with cystic fibrosis

    Directory of Open Access Journals (Sweden)

    Crésio de Aragão Dantas Alves

    2007-04-01

    Full Text Available Diabetes melito relacionado à fibrose cística (DMFC é a principal complicação extrapulmonar da fibrose cística. Atualmente, ele afeta 15-30% dos adultos com fibrose cística e sua prevalência tende a aumentar com o aumento da expectativa de vida desses pacientes. Esse trabalho tem por objetivo rever a fisiopatologia, morbidade, manifestações clínicas, diagnóstico e tratamento do DMFC. Uma pesquisa bibliográfica utilizou os bancos de dados Medline e Literatura Latino-Americana e do Caribe em Ciências da Saúde, selecionando artigos publicados nos últimos vinte anos. A insulinopenia secundária à destruição de células beta pancreáticas é o principal mecanismo causal, embora a resistência insulínica também possa estar presente. O DMFC apresenta características do diabetes melito tipo 1 e tipo 2 e tem início, em média, aos 20 anos de idade. Ele pode cursar com hiperglicemia em jejum, pós-prandial ou intermitente. As alterações do metabolismo glicêmico agravam o estado nutricional, aumentam a morbidade, diminuem a sobrevida e pioram a função pulmonar. As complicações microvasculares estão presentes, porém raramente observam-se as macrovasculares. A triagem para o DMFC deve ser anual, a partir dos 10 anos de idade, através do teste de tolerância oral à glicose e, em qualquer faixa etária, se houver perda ponderal inexplicada ou sintomatologia de diabetes. Pacientes hospitalizados também devem ser investigados e receber terapia insulínica se a hiperglicemia em jejum persistir além de 48 h. A insulina é o tratamento de escolha para o diabetes com hiperglicemia em jejum. Não existe consenso quanto ao tratamento do diabetes intermitente ou sem hiperglicemia de jejum. Não há orientações de restrições alimentares. O acompanhamento deve ser multidisciplinar.Cystic fibrosis-related diabetes (CFRD is the principal extra-pulmonary complication of cystic fibrosis, occurring in 15-30% of adult cystic fibrosis

  2. Cross-activating invariant NKT cells and kupffer cells suppress cholestatic liver injury in a mouse model of biliary obstruction.

    Directory of Open Access Journals (Sweden)

    Caroline C Duwaerts

    Full Text Available Both Kupffer cells and invariant natural killer T (iNKT cells suppress neutrophil-dependent liver injury in a mouse model of biliary obstruction. We hypothesize that these roles are interdependent and require iNKT cell-Kupffer cell cross-activation. Female, wild-type and iNKT cell-deficient C57Bl/6 mice were injected with magnetic beads 3 days prior to bile duct ligation (BDL in order to facilitate subsequent Kupffer cell isolation. On day three post-BDL, the animals were euthanized and the livers dissected. Necrosis was scored; Kupffer cells were isolated and cell surface marker expression (flow cytometry, mRNA expression (qtPCR, nitric oxide (NO (. production (Griess reaction, and protein secretion (cytometric bead-array or ELISAs were determined. To address the potential role of NO (. in suppressing neutrophil accumulation, a group of WT mice received 1400W, a specific inducible nitric oxide synthase (iNOS inhibitor, prior to BDL. To clarify the mechanisms underlying Kupffer cell-iNKT cell cross-activation, WT animals were administered anti-IFN-γ or anti-lymphocyte function-associated antigen (LFA-1 antibody prior to BDL. Compared to their WT counterparts, Kupffer cells obtained from BDL iNKT cell-deficient mice expressed lower iNOS mRNA levels, produced less NO (. , and secreted more neutrophil chemoattractants. Both iNOS inhibition and IFN-γ neutralization increased neutrophil accumulation in the livers of BDL WT mice. Anti-LFA-1 pre-treatment reduced iNKT cell accumulation in these same animals. These data indicate that the LFA-1-dependent cross-activation of iNKT cells and Kupffer cells inhibits neutrophil accumulation and cholestatic liver injury.

    Since its first description in 1994, frontal fibrosing alopecia (FFA) has become increasingly common, suggesting that environmental factors are involved in the aetiology. To identify possible causative environmental factors in FFA. A questionnaire enquiring about exposure to a wide range of lifestyle, social and medical factors was completed by 105 women with FFA and 100 age- and sex-matched control subjects. A subcohort of women with FFA was patch tested to an extended British standard series of allergens. The use of sunscreens was significantly greater in the FFA group compared with controls. Subjects with FFA also showed a trend towards more frequent use of facial moisturizers and foundations but, compared with controls, the difference in frequencies just failed to reach statistical significance. The frequency of hair shampooing, oral contraceptive use, hair colouring and facial hair removal were significantly lower in the FFA group than in controls. Thyroid disease was more common in subjects with FFA than controls and there was a high frequency of positive patch tests in women with FFA, mainly to fragrances. Our findings suggest an association between FFA and the use of facial skin care products. The high frequency of sunscreen use in patients with FFA, and the fact that many facial skin care products now contain sunscreens, raises the possibility of a causative role for sunscreen chemicals. The high frequency of positive patch tests in women with FFA and the association with thyroid disease may indicate a predisposition to immune-mediated disease. © 2016 British Association of Dermatologists.

    Directory of Open Access Journals (Sweden)

    Cristiane Valle TOVO

    2013-03-01

    Full Text Available Context The progression of liver fibrosis in patients coinfected by hepatitis C virus and human immunodeficiency virus (HCV/HIV has been increasingly studied in the past decade. Studies made before the highly active antiretroviral therapy suggest that HIV can change the natural history of the HCV infection, leading to a faster progression of the liver fibrosis. Objective To evaluate and compare the fibrosis progression in two groups of patients (HCV/HIV coinfected and HCV monoinfected Methods Seventy patients HCV monoinfected and 26 patients HCV/HIV coinfected who had not undertaken HCV treatment and were submitted to serial percutaneous liver biopsies were retrospectively evaluated. There was no difference in the fibrosis progression between the two groups. Conclusion The fibrosis grade evolution was not worse in the coinfected patients. The immunosuppression absence and the shortest time period between the biopsies in the coinfected group are possible explanations. Contexto A progressão da fibrose hepática em pacientes coinfectados pelos vírus da hepatite C (VHC e da imunodeficiência humana (VHC/HIV tem sido mais estudada na última década. Estudos realizados antes da terapia antiretroviral de alta potência (HAART sugerem que o HIV pode mudar a história natural da infecção pelo VHC, levando a uma progressão mais rápida da fibrose hepática. Objetivo Avaliar e comparar a progressão de fibrose em duas populações de pacientes (coinfectados VHC/HIV e monoinfectados VHC. Métodos Foram avaliados retrospectivamente 70 pacientes monoinfectados VHC e 26 coinfectados VHC/HIV nunca tratados para o VHC e que haviam realizado duas biopsias hepáticas seriadas. Não houve diferença na progressão de fibrose entre os dois grupos. Conclusão A evolução do grau de fibrose não foi pior nos pacientes coinfectados. A ausência de imunodepressão e o menor intervalo de tempo entre as biopsias no grupo de coinfectados são poss

  16. Novel syndrome of four-limb proximal fragility fractures associated with HIV infection, cholestatic liver failure, and histiocytic infiltration of bone marrow.

    Science.gov (United States)

    Yu, Run; Nissen, Nicholas N; Balzer, Bonnie; Fan, Xuemo

    2012-01-01

    We report a syndrome of four-limb proximal fragility fractures associated with HIV infection, cholestatic liver failure, and histiocytic infiltration of bone marrow in a 40-year-old African American man. The patient presented with multiple fractures in the proximal humeri and femurs without osteopenia in the vertebrae. His right humerus appeared normal on chest X-ray film 3 years before presentation when he was first diagnosed with HIV infection and abnormal liver functions. At presentation, the patient had vitamin D deficiency, hypogonadism, and low IGF- 1 levels, but did not have hyperparathyroidism. Bone biopsy showed diffuse foamy histiocytic infiltration of bone marrow at all fracture sites without evidence of infectious or neoplastic processes. Exhaustive search did not identify any similar cases in the English literature. Our case likely represents a novel syndrome, the etiology of which is probably multifactorial and includes HIV infection, cholestatic liver failure, immobility, and endocrine abnormalities. The case further calls for the need for monitoring of bone health in patients with HIV infection or liver disease.

  17. Hormesis in Cholestatic Liver Disease; Preconditioning with Low Bile Acid Concentrations Protects against Bile Acid-Induced Toxicity.

    Directory of Open Access Journals (Sweden)

    Esther M Verhaag

    Full Text Available Cholestasis is characterized by accumulation of bile acids and inflammation, causing hepatocellular damage. Still, liver damage markers are highest in acute cholestasis and drop when this condition becomes chronic, indicating that hepatocytes adapt towards the hostile environment. This may be explained by a hormetic response in hepatocytes that limits cell death during cholestasis.To investigate the mechanisms that underlie the hormetic response that protect hepatocytes against experimental cholestatic conditions.HepG2.rNtcp cells were preconditioned (24 h with sub-apoptotic concentrations (0.1-50 μM of various bile acids, the superoxide donor menadione, TNF-α or the Farsenoid X Receptor agonist GW4064, followed by a challenge with the apoptosis-inducing bile acid glycochenodeoxycholic acid (GCDCA; 200 μM for 4 h, menadione (50 μM, 6 h or cytokine mixture (CM; 6 h. Levels of apoptotic and necrotic cell death, mRNA expression of the bile salt export pump (ABCB11 and bile acid sensors, as well as intracellular GCDCA levels were analyzed.Preconditioning with the pro-apoptotic bile acids GCDCA, taurocholic acid, or the protective bile acids (tauroursodeoxycholic acid reduced GCDCA-induced caspase-3/7 activity in HepG2.rNtcp cells. Bile acid preconditioning did not induce significant levels of necrosis in GCDCA-challenged HepG2.rNtcp cells. In contrast, preconditioning with cholic acid, menadione or TNF-α potentiated GCDCA-induced apoptosis. GCDCA preconditioning specifically reduced GCDCA-induced cell death and not CM- or menadione-induced apoptosis. The hormetic effect of GCDCA preconditioning was concentration- and time-dependent. GCDCA-, CDCA- and GW4064- preconditioning enhanced ABCB11 mRNA levels, but in contrast to the bile acids, GW4064 did not significantly reduce GCDCA-induced caspase-3/7 activity. The GCDCA challenge strongly increased intracellular levels of this bile acid, which was not lowered by GCDCA

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

    Full Text Available MicroRNA-29 (miR-29 is found to modulate hepatic stellate cells’ (HSCs activation and, thereby, reduces liver fibrosis pathogenesis. Histone methyltransferase regulation of epigenetic reactions reportedly participates in hepatic fibrosis. This study is undertaken to investigate the miR-29a regulation of the methyltransferase signaling and epigenetic program in hepatic fibrosis progression. miR-29a transgenic mice (miR-29aTg mice and wild-type littermates were subjected to bile duct-ligation (BDL to develop cholestatic liver fibrosis. Primary HSCs were transfected with a miR-29a mimic and antisense inhibitor. Profibrogenic gene expression, histone methyltransferases and global genetic methylation were probed with real-time quantitative RT-PCR, immunohistochemical stain, Western blot and ELISA. Hepatic tissue in miR-29aTg mice displayed weak fibrotic matrix as evidenced by Sirius Red staining concomitant with low fibrotic matrix collagen 1α1 expression within affected tissues compared to the wild-type mice. miR-29a overexpression reduced the BDL exaggeration of methyltransferases, DNMT1, DNMT3b and SET domain containing 1A (SET1A expression. It also elevated phosphatase and tensin homolog deleted on chromosome 10 (PTEN signaling within liver tissue. In vitro, miR-29a mimic transfection lowered collagen 1α1, DNMT1, DNMT3b and SET1A expression in HSCs. Gain of miR-29a signaling resulted in DNA hypomethylation and high PTEN expression. This study shines a new light on miR-29a inhibition of methyltransferase, a protective effect to maintain the DNA hypomethylation state that decreases fibrogenic activities in HSC. These robust analyses also highlight the miR-29a regulation of epigenetic actions to ameliorate excessive fibrosis during cholestatic liver fibrosis development.

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

    The 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.

    Autoimmune hepatitis (AIH) is characterised histologically by interface hepatitis, and serologically by the presence of non-organ and liver specific autoantibodies and increased levels of immunoglobulin G. Its onset is often ill-defined, frequently mimicing acute hepatitis. AIH usually responds to immunosuppressive treatment, which should be instituted as soon as diagnosis is made. Two types of AIH are recognized according to seropositivity for smooth muscle and/or antinuclear antibody (SMA/ANA, type 1 AIH) or liver kidney microsomal type 1 antibody (LKM1, type 2 AIH). There is a female predominance in both. LKM1 positive patients tend to present more acutely, at a younger age and commonly have immunoglobulin A deficiency, while duration of symptoms before diagnosis, clinical signs, family history of autoimmunity, presence of associated autoimmune disorders, response to treatment and long-term prognosis are similar in the 2 groups. Susceptibility to AIH type 1 is conferred by possession of HLA DR3 and DR4, while to AIH type 2 by possession of HLA DR7. Liver damage is likely to derive from an immune reaction to liver cell antigens, possibly triggered by a mechanism of molecular mimicry, where immune responses to external pathogens, e.g. viruses, become directed towards structurally similar self-components. In AIH this process would be perpetuated by impairment in immune regulation.

    2008-02-01

    Full Text Available A fibrose cística, que já foi considerada uma doença da infância, é agora também uma doença do adulto. O aumento da longevidade resultou em mais problemas médicos relacionados com a idade e com a própria doença. O crescente número de adultos com fibrose cística resultou em aumento da necessidade de cuidados médicos. Essa necessidade tem sido suprida por um crescente número de pneumologistas de adultos e outros especialistas. O objetivo dessa revisão é sumarizar o conhecimento corrente sobre o diagnóstico e tratamento no adulto com fibrose cística. Na maioria dos casos, o diagnóstico é sugerido por manifestações de doença sinopulmonar crônica e insuficiência pancreática exócrina, e, então, confirmado por um teste do suor positivo. Pacientes adultos podem, entretanto, apresentar suficiência pancreática e características clínicas atípicas, às vezes, associadas com teste do suor normal ou limítrofe. Em tais casos, a possibilidade de realizar pesquisa de mutações para fibrose cística e de medir a diferença de potencial nasal pode ser de utilidade diagnóstica. A abordagem terapêutica padrão para a doença pulmonar inclui: antibióticos, higiene das vias aéreas, exercício, mucolíticos, broncodilatadores, oxigênio, agentes anti-inflamatórios e suporte nutricional. A utilização adequada dessas terapias resulta em mais pacientes com fibrose cística sobrevivendo na vida adulta com uma aceitável qualidade de vida.Once considered a childhood disease, cystic fibrosis is now also a disease of adults.

    Organising pneumonia (otherwise referred to as bronchiolitis obliterans organising pneumonia) is characterised histologically by plugs of granulation tissue, which are present predominantly within small airways, alveolar ducts and peri-bronchiolar alveoli. This pattern is not specific for any disorder or cause, but is one type of inflammatory response to pulmonary injury, which may be seen in a wide variety of clinical conditions. Typically, organising pneumonia responds very well to corticosteroid treatment; however, a small percentage of patients appear to develop progressive fibrosis.

Abstract: Reported for the first time in 1996, aquagenic keratoderma is a rare condition which is characterized by edematous flat-topped papules appearing on palmar skin after water immersion. Multiple anecdotal associations have been described but, recently, the association with cystic fibrosis gene mutations (CFTR has been highlighted.The authors describe an 18 year-old female, with one-month complaints of pruritus and swelling of palmar skin after water immersion. On examination, palmar skin was unremarkable but, 5 minutes after water immersion, multiple whitish papules became apparent. CFTR genotype study showed a F508del mutation in one alelle. She had no other symptoms and no relevant family history.Aquagenic keratoderma is probably an under-diagnosed entity that might represent a manifestation of CFTR mutations, making carrier state identification and genetic counseling possible.

    Hereditary Fibrosing Poikiloderma (HFP) with tendon contractures, myopathy and pulmonary fibrosis (POIKTMP [MIM 615704]) is a very recently described entity of syndromic inherited poikiloderma. Previously by using whole exome sequencing in five families, we identified the causative gene, FAM111B (NM_198947.3), the function of which is still unknown. Our objective in this study was to better define the specific features of POIKTMP through a larger series of patients. Clinical and molecular data of two families and eight independent sporadic cases, including six new cases, were collected. Key features consist of: (i) early-onset poikiloderma, hypotrichosis and hypohidrosis; (ii) multiple contractures, in particular triceps surae muscle contractures; (iii) diffuse progressive muscular weakness; (iv) pulmonary fibrosis in adulthood and (v) other features including exocrine pancreatic insufficiency, liver impairment and growth retardation. Muscle magnetic resonance imaging was informative and showed muscle atrophy and fatty infiltration. Histological examination of skeletal muscle revealed extensive fibroadipose tissue infiltration. Microscopy of the skin showed a scleroderma-like aspect with fibrosis and alterations of the elastic network. FAM111B gene analysis identified five different missense variants (two recurrent mutations were found respectively in three and four independent families). All the mutations were predicted to localize in the trypsin-like cysteine/serine peptidase domain of the protein. We suggest gain-of-function or dominant-negative mutations resulting in FAM111B enzymatic activity changes. HFP with tendon contractures, myopathy and pulmonary fibrosis, is a multisystemic disorder due to autosomal dominant FAM111B mutations. Future functional studies will help in understanding the specific pathological process of this fibrosing disorder.

Foram realizadas avaliação da distribuição de gordura corporal por meio da absorciometria de duplo feixe de energia, do estado nutricional por estatura/idade e índice de massa corporal/idade e a ingestão dietética pelo recordatório alimentar de 24horas, em 56 pacientes com idade entre 8 e 18 anos. Aproximadamente 50% da amostra apresentou estado nutricional adequado. A maioria apresentou a ingestão calórica e de lipídios inadequadas. O IMC/I foi o indicador nutricional que melhor evidenciou o aumento do percentual de gordura do tronco, razão androide/ginecoide e razão gordura tronco/gordura total. Os pacientes com Insuficiência Pancreática e os eutróficos apresentaram razão mediana androide/ginecoide maior. O aumento da adiposidade abdominal foi evidenciado pela DXA. O IMC/I não identificou a diminuição da massa magra corporal, mas quando aumentado foi significativo para adiposidade abdominal. Pacientes com fibrose cística devem associar a avaliação antropométrica à composição corporal e à distribuição de gordura corporal para um diagnóstico mais precoce de desnutrição e fatores de risco cardiometabólico.

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

MÉTODOS: Setenta fibrocísticos foram acompanhados prospectivamente e submetidos a exame clínico, bioquímico e ultra-sonográfico. Os achados ultra-sonográficos foram comparados com os resultados do exame clínico e bioquímico. Para a validação do escore ultra-sonográfico de Williams, os critérios clínicos e bioquímicos foram utilizados como padrão-ouro. Foram calculados sensibilidade, especificidade, valor preditivo positivo e valor preditivo negativo do escore de Williams. Para os cálculos, os pacientes foram divididos em dois grupos: normal ao exame ultra-sonográfico (escore = 3 ou alterado (escore > 3. RESULTADOS: Dez pacientes preencheram os critérios clínicos e/ou bioquímicos para hepatopatia (14,3%. Todos os pacientes hepatopatas segundo os critérios clínicos e/ou bioquímicos apresentavam alguma alteração ao exame ultra-sonográfico. As alterações do parênquima hepático, borda hepática e fibrose periportal foram encontradas mais freqüentemente entre os hepatopatas, com diferença estatisticamente significativa. O escore de Williams apresentou alta especificidade (91,7%; IC 80,9-96,9, mas baixa sensibilidade (s = 50%; IC 20,1-79,9 para o diagnóstico da hepatopatia. CONCLUSÕES: O escore de Williams não constituiu um bom exame de triagem quando comparado ao exame clínico e bioquímico. Uma vez que ainda não há nenhum teste que, utilizado isoladamente, apresente sensibilidade adequada, é recomendável a utilização conjunta dos exames clínico, bioquímico e ultra-sonográfico no diagnóstico da hepatopatia associada à fibrose cística, sempre em avalia

    2014-04-01

    Full Text Available “Nutritional supplements” that promise an increase in muscle mass and strength are becoming a go to item as enhancing one’s physical appearance becomes a more important part of our society. This is alarming because many of these nutritional supplements rely on androgen precursors to deliver their promises, without adequately informing consumers of the potential side effects of such agents. These products may conceal the presence of potent androgens to avoid regulatory sanctions and become more appealing to consumers. Recent reports have shown that some products marketed as “nutritional supplements” have been found to contain androgenic anabolic steroids. Methylstenbolone and dymethazine are new androgenic anabolic steroids currently gaining popularity among body builders for their performance-enhancing properties and rapid effects on muscle mass. These agents are found together in Super DMZ Rx 2.0, a “dietary supplement” for bodybuilders. Here we report the first case of Super DMZ Rx 2.0–induced cholestatic jaundice in a 26-year-old previously healthy Caucasian male, who took the supplement according to the manufacturer’s instructions for 30 days.

    Full Text Available Huang-Lian-Jie-Du-Decoction, a traditional Chinese formula, has been reported to protect liver from various injuries. Two cholestasis models of rats induced by thioacetamide and by bile duct ligation were established and treated with Huang-Lian-Jie-Du-Decoction. Nuclear Magnetic Resonance-based urinary metabolic profiles were analyzed by orthogonal partial least squares discriminant analysis and univariate analysis to excavate differential metabolites associated with the injuries of the two models and the treatment effects of Huang-Lian-Jie-Du-Decoction. The two cholestatic models shared common metabolic features of excessive fatty acid oxidation, insufficient glutathione regeneration and disturbed gut flora, with specific characteristics of inhibited urea cycle and DNA damage in thioacetamide-intoxicated model, and perturbed Kreb's cycle and inhibited branched chain amino acid oxidation in bile duct ligation model. With good treatment effects, Huang-Lian-Jie-Du-Decoction could regain the balance of the disturbed metabolic status common in the two cholestasis injuries, e.g., unbalanced redox system and disturbed gut flora; and perturbed urea cycle in thioacetamide-intoxicated model and energy crisis (disturbed Kreb's cycle and oxidation of branched chain amino acid in bile duct ligation model, respectively.

    Several hepatobiliary disorders have been reported in ulcerative colitis (UC) patients with primary sclerosing cholangitis (PSC) being the most specific. Primary biliary cholangitis (PBC), previously known as primary biliary cirrhosis, rarely occurs in UC. We present two PBC cases of 67 and 71 years who suffered from long-standing UC. Both patients were asymptomatic but they had increased cholestatic enzymes and high titres of antimitochondrial antibodies (AMA)-the laboratory hallmark of PBC. After careful exclusion of other causes of cholestasis by MRI/magnetic resonance cholangiopancreatography (MRCP), virological and microbiological investigations, a diagnosis of PBC associated with UC was established. The patients started ursodeoxycholic acid (13 mg/kg/day) with complete response. During follow-up, both patients remained asymptomatic with normal blood biochemistry. Although PSC is the most common hepatobiliary manifestation among patients with UC, physicians must keep also PBC in mind in those with unexplained cholestasis and repeatedly normal MRCP. In these cases, a reliable AMA testing can help for an accurate diagnosis. © BMJ Publishing Group Ltd (unless otherwise stated in the text of the article) 2017. All rights reserved.

    Full Text Available Background. The proper use of new medical tests in clinical practice requires the establishment of their value and range of diagnostic usefulness. While whole-exome sequencing (WES has already entered the medical practice, recognizing its diagnostic usefulness in multifactorial diseases has not yet been achieved. Aims. The objective of this study was to establish usability of WES in determining genetic background of chronic cholestatic liver disease (CLD in young patients. Methods. WES was performed on six young patients (between 17 and 22 years old with advanced fibrosis or cirrhosis due to CLD and their immediate families. Sequencing was performed on an Ion Proton sequencer. Results. On average, 19,673 variants were identified, of which from 7 to 14 variants of an individual were nonsynonymous, homozygous, recessively inherited, and considered in silico as pathogenic. Although monogenic cause of CLD has not been determined, several heterozygous rare variants and polymorphisms were uncovered in genes previously known to be associated with CLD, including ATP8B1, ABCB11, RXRA, and ABCC4, indicative of multifactorial genetic background. Conclusions. WES is a potentially useful diagnostic tool in determining genetic background of multifactorial diseases, but its main limitation results from the lack of opportunities for direct linkage between the uncovered genetic variants and molecular mechanisms of disease.

    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

  10. Role of glucuronidation for hepatic detoxification and urinary elimination of toxic bile acids during biliary obstruction.

    Directory of Open Access Journals (Sweden)

    Martin Perreault

    Full Text Available Biliary obstruction, a severe cholestatic condition, results in a huge accumulation of toxic bile acids (BA in the liver. Glucuronidation, a conjugation reaction, is thought to protect the liver by both reducing hepatic BA toxicity and increasing their urinary elimination. The present study evaluates the contribution of each process in the overall BA detoxification by glucuronidation. Glucuronide (G, glycine, taurine conjugates, and unconjugated BAs were quantified in pre- and post-biliary stenting urine samples from 12 patients with biliary obstruction, using liquid chromatography-tandem mass spectrometry (LC-MS/MS. The same LC-MS/MS procedure was used to quantify intra- and extracellular BA-G in Hepatoma HepG2 cells. Bile acid-induced toxicity in HepG2 cells was evaluated using MTS reduction, caspase-3 and flow cytometry assays. When compared to post-treatment samples, pre-stenting urines were enriched in glucuronide-, taurine- and glycine-conjugated BAs. Biliary stenting increased the relative BA-G abundance in the urinary BA pool, and reduced the proportion of taurine- and glycine-conjugates. Lithocholic, deoxycholic and chenodeoxycholic acids were the most cytotoxic and pro-apoptotic/necrotic BAs for HepG2 cells. Other species, such as the cholic, hyocholic and hyodeoxycholic acids were nontoxic. All BA-G assayed were less toxic and displayed lower pro-apoptotic/necrotic effects than their unconjugated precursors, even if they were able to penetrate into HepG2 cells. Under severe cholestatic conditions, urinary excretion favors the elimination of amidated BAs, while glucuronidation allows the conversion of cytotoxic BAs into nontoxic derivatives.

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

    Alcoholic hepatitis (AH) is an acute inflammatory syndrome causing significant morbidity and mortality. The prognosis is strongly dependent on disease severity, as assessed by clinical scoring systems. Reliable epidemiological data as well as knowledge of the clinical course of AH are essential for planning and resource allocation within the health care system. Likewise, individual evaluation of risk is desirable in the clinical handling of patients with AH as it can guide treatment, improve patient information, and serve as strata in clinical trials. The present PhD thesis is based on three studies using a cohort of nearly 2000 patients diagnosed with AH in Denmark from 1999 to 2008 as a cohort, in a population-based study design. The aims of this thesis were as follows. (1) To describe the incidence and short- and long-term mortality, of AH in Denmark (Study I). (2) To validate and compare the ability of the currently available prognostic scores to predict mortality in AH (Study II). (3) To investigate the short- and long-term causes of death of patients with AH (Study III). During the study decade, the annual incidence rate in the Danish population rose from 37 to 46 per 106 for men and from 24 to 34 per 106 for women. Both short- and long-term mortality rose for men and women, and the increase in short-term mortality was attributable to increasing patient age and prevalence of cirrhosis. Our evaluation of the most commonly used prognostic scores for predicting the mortality of patients with AH showed that all scores performed similarly, with Area under the Receiver Operator Characteristics curves giving values between 0.74 and 0.78 for 28-day mortality assessed on admission. Our study on causes of death showed that in the short-term (thesis provides novel warranted epidemiological information about AH that shows increasing incidence and mortality rates. Consequently, it reiterates the fact that AH is a life-threatening disease and suggests that AH is an

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

    Full Text Available INTRODUÇÃO: A Insuficiência Renal Crônica (IRC tem incidência alarmante neste século. A diálise peritoneal, uma das modalidades de terapia renal pode ter complicações, e entre estas a fibrose peritoneal, que ocorre com o decorrer dos anos nestes pacientes. Sua forma mais grave é a chamada peritonite esclerosante encapsulante, levando à mudança de terapia dialítica. OBJETIVO: Estudar a influência do uso do captopril na fibrose peritoneal induzida em ratos pelo uso de solução de glicose a 4,25 %. MÉTODOS: Estudo prospectivo controlado, em ratos Wistar não urêmicos. Foram estudados 20 animais. Os animais foram submetidos diariamente à punção abdominal, sendo infundida solução de diálise peritoneal com glicose a 4,25% na dose de 10 ml/100 g de peso. Os animais foram divididos em 2 grupos: experimental e controle. O grupo experimental recebeu captopril na dose de 30 mg/kg/dia por gavagem. O grupo controle não recebeu nenhuma droga. Foram acompanhados por 21 e 49 dias. Ao final do período foram submetidos à procedimento cirúrgico para retirada de peritônio parietal e visceral. As amostras obtidas foram analisadas histologicamente, usando-se coloração Hematoxilina - Eosina e Sirius Red, para avaliação do grau de fibrose. RESULTADOS: A análise mostrou que a intensidade da fibrose, a espessura do peritônio e o número de células não atingiram diferença estatisticamente significante entre os grupos experimental e controle. CONCLUSÃO: O estudo mostrou que o uso do captopril não foi capaz de alterar a intensidade da fibrose peritoneal induzida pelo uso de solução de diálise em ratos.

    Full Text Available Background. Amyloidosis represents a group of different diseases characterized by extracellular accumulation of pathologic fibrillar proteins in various tissues and organs. Severe amyloid deposition in the liver parenchyma has extrahepatic involvement predominantly in the kidney or heart. We evaluated the effect of ursodeoxycholic acid, in four patients with severe hepatic amyloidosis of different etiologies, who presented with increased alkaline phosphatase and γ-glutamyl transferase. Case report. The study included four patients who presented with amyloidosis-associated intrahepatic cholestasis. Three of them had renal amyloidosis which developed 1-3 years before cholestasis occurred, the remaining one having intrahepatic cholestasis as the primary sign of the disease. Amyloidosis was identified from liver biopsies in all patients by its specific binding to Congo red and green birefringence in polarized light. The biochemical nature and the class of amyloid deposits were identified immunohistochemically. In addition to their regular treatment, the patients received 750 mg ursodeoxycholic acid per day. After 2-4 weeks all patients had a significant decrease of serum alkaline phosphatase and γ-glutamyl transferase, and their general status significantly improved. Conclusion. Treatment with ursodeoxycholic acid may be beneficial in patients with hepatic amyloidosis, and do extend indications for the use of ursodeoxycholic acid in amyloidotic cholestatic liver disease.

Animals in Group 1 (control underwent sham laparotomy. The animals of groups 2 and 3 underwent ligation and section of the hepatic duct and were kept in cholestasis for four weeks. Next, they underwent an internal biliary bypass. In Group 3, besides the biliary-enteric bypass, we associated the exclusion of the last ten centimeters of the terminal ileum and carried out an ileocolic anastomosis. After four weeks of monitoring, blood was collected from all animals of the three groups for liver and kidney biochemical evaluation (albumin, ALT, AST, direct and indirect bilirubin, alkaline phosphatase, cGT, creatinine and urea.RESULTS: there were increased values of ALT, AST, direct bilirubin, cGT, creatinine and urea in rats from Group 3 (p < 0.05.CONCLUSION: ileal exclusion worsened liver and kidney functions in the murine model of extrahepatic cholestasis, being disadvantageous as therapeutic procedure for cholestatic disorders.

    Cholestatic jaundice in infancy affects approximately 1 in every 2500 term infants and is infrequently recognized by primary providers in the setting of physiologic jaundice. Cholestatic jaundice is always pathologic and indicates hepatobiliary dysfunction. Early detection by the primary care physician and timely referrals to the pediatric gastroenterologist/hepatologist are important contributors to optimal treatment and prognosis. The most common causes of cholestatic jaundice in the first months of life are biliary atresia (25%-40%) followed by an expanding list of monogenic disorders (25%), along with many unknown or multifactorial (eg, parenteral nutrition-related) causes, each of which may have time-sensitive and distinct treatment plans. Thus, these guidelines can have an essential role for the evaluation of neonatal cholestasis to optimize care. The recommendations from this clinical practice guideline are based upon review and analysis of published literature and the combined experience of the authors. The committee recommends that any infant noted to be jaundiced after 2 weeks of age be evaluated for cholestasis with measurement of total and direct serum bilirubin, and that an elevated serum direct bilirubin level (direct bilirubin levels >1.0 mg/dL or >17 μmol/L) warrants timely consideration for evaluation and referral to a pediatric gastroenterologist or hepatologist. Of note, current differential diagnostic plans now incorporate consideration of modern broad-based next-generation DNA sequencing technologies in the proper clinical context. These recommendations are a general guideline and are not intended as a substitute for clinical judgment or as a protocol for the care of all infants with cholestasis. Broad implementation of these recommendations is expected to reduce the time to the diagnosis of pediatric liver diseases, including biliary atresia, leading to improved outcomes.

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

    Full Text Available La hepatitis isquémica es una complicación sumamente infrecuente de cirugía cardiovascular. Las biopsias muestran necrosis centrolobulillar. El término de "hepatitis" fue propuesto debido al aumento de transaminasas similar a aquellas de origen infeccioso, e "isquémica" por falla en la perfusión hepática. Posteriormente se definió el término de hepatitis isquémica como cuadro de elevación aguda y reversible (dentro de las 72 horas de transaminasas de hasta 20 veces el valor normal, asociado a trastornos en la perfusión hepática, luego de haber excluido otras causas de hepatitis aguda o daño hepatocelular.

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

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

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

    BACKGROUND AND RATIONALE FOR THE STUDY: IL-17, TGF-β1/2 are cytokines involved in the development of kidney, pulmonary and liver fibrosis. However, their expression kinetics in the pathogenesis of cholestatic liver fibrosis have not yet been fully explored. The aim of the study was to analyze the expression of IL-17, RORγt, NKp46, TGF-β1, and TGF-β2 in the liver of rats with bile duct ligation (BDL). Hepatic IL-17A gene expression analyzed by qRT-PCR showed a dramatic increase of 350 and 10 fold, at 8 and 30 days post BDL, respectively. TGFβ1 and TGFβ2 gene expression significantly increased throughout the whole fibrotic process. At the protein level in liver homogenates, IL-17, TGF-β1, and RORγt significantly increased at 8 and 30 days after BDL. Interestingly, a significant increase in the protein levels of TGF-β2 and decrease of NKp46 was observed only 30 days after BDL. Unexpectedly, TGF-β2 exhibited stronger signals than TGF-β1 at the gene expression and protein levels. Histological analysis showed bile duct proliferation and collagen deposition. Our results suggest that pro-fibrogenic cytokines IL-17, TGF-β1 and, strikingly, TGF-β2 might be important players of liver damage in the pathogenesis of early and advanced experimental cholestatic fibrosis. Th17 cells might represent an important source of IL-17, while NK cell depletion may account for the perpetuation of liver damage in the BDL model.

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

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

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

    2006-01-01

    Full Text Available The cirrhosis represents the final stage of several chronic hepatic diseases and it is characterized by the presence of fibrosis and morphologic conversion from the normal hepatic architecture into structurally abnormal nodules. In the evolution of the disease there is loss of the normal vascular relationship and portal hypertension. There are also regenerative hepatocelular alterations that become more prominent with the progression of the disease. The liver transplantation continues to be the only therapeutic option in cases of disease in terminal phase. The hepatic stellate cells (HSC are perisinusoidal cells that store vitamin A and produce growth factors, citocins, prostaglandins and other bioactive substances. They can suffer an activation process that convert them to cells with a phenotype similar to myofibroblasts. When activated, they present increased capacity of proliferation, mobility, contractility and synthesis of collagen and other components of extracelular matrix. They possess cytoplasmic processes adhered to sinusoids and can affect the sinusoidal blood flow. HSC are important in pathogenesis of fibrosis and portal hypertension.A cirrose representa o estágio final de diversas doenças hepáticas crônicas e é caracterizada pela presença de fibrose e conversão da arquitetura hepática normal em nódulos estruturalmente anormais. Na evolução da doença ocorre perda da relação vascular normal e hipertensão portal. Há também alterações regenerativas hepatocelulares que se tornam mais proeminentes com a progressão da doença. O transplante hepático permanece como a única opção terapêutica nos casos de doença em fase terminal.

    2017-05-01

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

    Tartrazine is a food colour that activates the transcriptional function of the human oestrogen receptor alpha in an in vitro cell model. Since oestrogens are cholestatic, we hypothesised tartrazine will cause periportal injury to the liver in vivo. To test this hypothesis, tartrazine was initially administered systemically to mice resulting in a periportal recruitment of inflammatory cells, increased serum alkaline phosphatase activity and mild periportal fibrosis. To determine whether an oestrogenic effect may be a key event in this response, tartrazine, sulphonated metabolites and a food additive contaminant were screened for their ability to interact with murine oestrogen receptors. In all cases, there were no interactions as agonists or antagonists and further, no oestrogenicity was observed with tartrazine in an in vivo uterine growth assay. To examine the relevance of the hepatic effects of tartrazine to its use as a food additive, tartrazine was orally administered to transgenic NF-κB-Luc mice. Pre- and concurrent oral treatment with alcohol was incorporated given its potential to promote gut permeability and hepatic inflammation. Tartrazine alone induced NF- κB activities in the colon and liver but there was no periportal recruitment of inflammatory cells or fibrosis. Tartrazine, its sulphonated metabolites and the contaminant inhibited sulphotransferase activities in murine hepatic S9 extracts. Given the role of sulfotransferases in bile acid excretion, the initiating event giving rise to periportal inflammation and subsequent hepatic pathology through systemic tartrazine exposure is therefore potentially associated an inhibition of bile acid sulphation and excretion and not on oestrogen receptor-mediated transcriptional function. However, these effects were restricted to systemic exposures to tartrazine and did not occur to any significant effect after oral exposure. Copyright © 2017 The Authors. Published by Elsevier B.V.

    α7-nAChR is a nicotinic acetylcholine receptor (specifically expressed on hepatic stellate cells, Kupffer cells, and cholangiocytes) that regulates inflammation and apoptosis in the liver. Thus, targeting α7-nAChR may be therapeutic in biliary diseases. Bile-duct ligation (BDL) was performed on wild-type (WT) and α7-nAChR-/- mice. We first evaluated the expression of α7-nAChR by immunohistochemistry (IHC) in liver sections. IHC was also performed to assess intrahepatic bile-duct mass (IBDM), and Sirius Red staining was performed to quantify the amount of collagen deposition. Immunofluorescence was performed to assess co-localization of α7-nAChR with bile ducts (co-stained with CK-19) and hepatic stellate cells (HSCs) (co-stained with desmin). The mRNA expression of α7-nAChR, Ki67/PCNA (proliferation), fibrosis genes (TGF-β1, Fibronectin-1, Col1α1, and α-SMA), and inflammatory markers (IL-6, IL-1β, and TNFα) was measured by real-time PCR. Biliary TGF-β1 and hepatic CD68 (Kupffer cell marker) expression was assessed using IHC. α7-nAChR immunoreactivity was observed in both bile ducts and HSCs and increased following BDL. α7-nAChR-/- BDL mice exhibited decreased: (i) bile duct mass, liver fibrosis, and inflammation; and (ii) immunoreactivity of TGF-1 as well as expression of fibrosis genes compared to WT BDL mice. α7-nAChR activation triggers biliary proliferation and liver fibrosis and may be a therapeutic target in managing extra-hepatic biliary obstruction.

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

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

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

    Full Text Available Hugh James FreemanDepartment of Medicine (Gastroenterology, University of British Columbia, Vancouver, British Columbia, CanadaAbstract: Different hepatic and biliary tract disorders may occur with celiac disease. Some have been hypothesized to share genetic or immunopathogenetic factors, such as primary biliary cirrhosis, primary sclerosing cholangitis, and autoimmune hepatitis. Other hepatic changes in celiac disease may occur with malnutrition resulting from impaired nutrient absorption, including hepatic steatosis. In addition, celiac disease may be associated with rare hepatic complications, such as hepatic T-cell lymphoma.Keywords: celiac disease, autoimmune liver disease, primary biliary cirrhosis, fatty liver, gluten-free diet

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

    2013-01-01

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

    Full Text Available A 22 year-old horse developed cholelithiasis with marked atrophy of the right lateral hepatic lobe. The horse had a history of intermittent colic since three years of age, and one of the first episodes of colic was associated with icterus. The size of the right lateral hepatic lobe was extremely reduced. There was a large choledocholith in the common hepatic duct, and several hepatoliths and choleliths in the intra- and extra-hepatic billiary ducts. Microscopically, there was severe atrophy of the right lobe with diffuse proliferation of connective tissue and billiary ducts. The left lateral lobe had peri-portal fibrosis with proliferation of billiary ducts, and billiary stasis. Chemical analysis of the calculi detected amorphous and triple phosphate, bilirubin, calcium, and iron.Um cavalo de 22 anos de idade desenvolveu quadro de colelitíase severa com atrofia do lobo lateral direito. O animal tinha histórico de cólica recorrente, desde os três anos de idade, sendo que um dos primeiros episódios de cólica foi acompanhado de icterícia. O lobo hepático lateral direito estava extremamente diminuído de volume. Havia um grande coledocólito localizado no ducto hepático comum e inúmeros hepatólitos e colélitos nos ductos biliares intra e extra-hepáticos. Microscopicamente, foi observada atrofia acentuada do lobo direito, com proliferação difusa de tecido conjuntivo fibroso e de ductos biliares. O lobo lateral esquerdo apresentava fibrose periportal difusa associada à proliferação acentuada de ductos biliares e estase biliar.

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

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

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

  20. Hepatic angiography: Portal hypertension

    International Nuclear Information System (INIS)

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

    1985-01-01

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

  1. Prophylactic Hepatitis E Vaccine.

    Zhang, Jun; Zhao, Qinjian; Xia, Ningshao

    2016-01-01

    Hepatitis E has been increasingly recognized as an underestimated global disease burden in recent years. Subpopulations with more serious infection-associated damage or death include pregnant women, patients with basic liver diseases, and elderly persons. Vaccine would be the most effective means for prevention of HEV infection. The lack of an efficient cell culture system for HEV makes the development of classic inactive or attenuated vaccine infeasible. Hence, the recombinant vaccine approaches are explored deeply. The neutralizing sites are located almost exclusively in the capsid protein, pORF2, of the virion. Based on pORF2, many vaccine candidates showed potential of protecting primate animals; two of them were tested in human and evidenced to be well tolerated in adults and highly efficacious in preventing hepatitis E. The world's first hepatitis E vaccine, Hecolin ® (HEV 239 vaccine), was licensed in China and launched in 2012.

    2011-01-01

    The hepatitis E virus (HEV) the causative agent of hepatitis E, is a non-enveloped RNA virus. HEV is transmitted through oral consumption of contaminated food and water According to the currently knowledge now be considered as zoonosis. The main reservoir of HEV are pigs, boars and deer. For the first time HEV was isolated from animals (pigs) in 1997 in the U.S. Genetic analysis of strains isolated from pigs showed high similarity to strains HEV isolated from humans. This was the first evidence showing that HEV is a zoonosis. Further studies have shown that occupational groups e.g. veterinarians, swine breeders with close contact to pigs have an increased risk for HEV infections. The additional evidence supported the zoonotic potential of HEV were reports of acute hepatitis E after the consumption of undercooked meat from deer and wild boar. Infection of HEV in the domestic pig and wild boar population in Europe is widespread.

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

Eighty five percent of the patients were clinically asymptomatic and their physical examinations sbowed unremarkable or minimal changes at the time of the liver biopsy Liver function tests tended to present slight abnormalities, involving mild elevations of the activity of the aminotransferases and gamma-glutamil transferase levels. In spite of these mild abnormalities advanced chronic liver disease ivas histologically detected in eighty nine percent of the patients, mainly showing chronic active hepatitis. The most characteristic histological finding ivas an interlobular bile duct damage which correlated with the presence of tymphoid aggregates in the portal tracts and with the development of fibrosis.Realizou-se estudo clinico-patológico de 163 casos não tratados de hepatite crônica C. A maioria dos pacientes era clinicamente assintomática e seus exames físicos demonstravam alterações inespecíficas ou mínimas por ocasião da biópsia hepática. As provas de função hepática tendiam a apresentar alterações discretas, envolvendo especialmente os níveis séricos das aminotransferases e gama-glutamil transpeptidase. Apesar destas alterações discretas, detectou-se doença hepática crônica histologicamente avançada, consistindo principalmente de hepatite crônica ativa. O achado histológico mais característico foi lesão de dueto biliar interlobular, que se correlacionou com a presença de agregados linfóides nos tratos portais e com o desenvolvimento de fibrose.

    Intrahepatic granuloma formation and fibrosis characterize the pathological features of Schistosoma mansoni infection. Based on previously observed substantial anti-fibrotic effects of 24-nor-ursodeoxycholic acid (norUDCA) in Abcb4/Mdr2(-/-) mice with cholestatic liver injury and biliary fibrosis, we hypothesized that norUDCA improves inflammation-driven liver fibrosis in S. mansoni infection. Adult NMRI mice were infected with 50 S. mansoni cercariae and after 12 weeks received either norUDCA- or ursodeoxycholic acid (UDCA)-enriched diet (0.5% wt/wt) for 4 weeks. Bile acid effects on liver histology, serum biochemistry, key regulatory cytokines, hepatic hydroxyproline content as well as granuloma formation were compared to naive mice and infected controls. In addition, effects of norUDCA on primary T-cell activation/proliferation and maturation of the antigen-presenting-cells (dendritic cells, macrophages) were determined in vitro. UDCA as well as norUDCA attenuated the inflammatory response in livers of S. mansoni infected mice, but exclusively norUDCA changed cellular composition and reduced size of hepatic granulomas as well as TH2-mediated hepatic fibrosis in vivo. Moreover, norUDCA affected surface expression level of major histocompatibility complex (MHC) class II of macrophages and dendritic cells as well as activation/proliferation of T-lymphocytes in vitro, whereas UDCA had no effect. This study demonstrates pronounced anti-inflammatory and anti-fibrotic effects of norUDCA compared to UDCA in S. mansoni induced liver injury, and indicates that norUDCA directly represses antigen presentation of antigen presenting cells and subsequent T-cell activation in vitro. Therefore, norUDCA represents a promising drug for the treatment of this important cause of liver fibrosis. Copyright © 2014 European Association for the Study of the Liver.

RESULTADOS: A amostra era composta de 62 indivíduos (46 mães e 16 pais. A prevalência atual de TEPT foi 6,5% e de TEPT parcial, de 19,4%. Os pais com e sem sintomas de TEPT diferiram significativamente em dois aspectos psicossociais: os primeiros relataram mais problemas emocionais (p = 0,001 e reconheceram mais frequentemente a necessidade de tratamento psiquiátrico ou psicológico (p = 0,002 que os últimos. Entretanto, somente 6,3% dos pais com sintomas de TEPT estavam em tratamento psiquiátrico/psicológico. CONCLUSÕES: Este estudo preliminar demonstrou que a frequência dos sintomas de TEPT é bem elevada em pais de pacientes com fibrose cística e, apesar de esses pais reconheceram que tem problemas emocionais e precisam de tratamento psiquiátrico/psicológico, seu sofrimento permanece invisível para o sistema médico, levando ao subdiagnóstico e ao subtratamento.BACKGROUND: Besides the growing acknowledgment of the relevance of posttraumatic stress disorder (PTSD related to medical illness, there is no study in cystic fibrosis yet.

    Full Text Available A fibrose pulmonar idiopática (alveolite fibrosante criptogênica é uma doença pulmonar intersticial progressiva de etiologia desconhecida, morfologicamente reconhecida como pneumonia intersticial usual. Desde a publicação de Hamman e Rich (1944 até os dias atuais, uma das grandes preocupações foi a tentativa de encontrar um marcador histológico para correlacionar com prognóstico e resposta terapêutica. A busca desta situação não tem sido muito alentadora, pois existem vários pontos duvidosos na patogênese desta doença. Admite-se que a resposta terapêutica desta entidade se relaciona com a celularidade e fibrose presentes no tecido. A proposta deste estudo é descrever os resultados de método semiquantitativo segundo a avaliação independente de dois patologistas, das alterações exsudativo-inflamatórias, reparativo-fibróticas e de vias aéreas, em 24 pacientes com diagnóstico de fibrose pulmonar idiopática, submetidos à biópsia a céu aberto. Foram analisados 14 parâmetros histológicos segundo escala de 0 a 5 para as alterações intersticiais e de 0 a 2 para o comprometimento de vias aéreas e de espaços aéreos. Da análise independente realizada pelos dois observadores constatou-se concordância significante em todas as variáveis histológicas com Kw (teste de Kappa indo de 0,47 a 0,92. Apenas na análise da intensidade da inflamação septal as discordâncias também foram significantes, sugerindo que para este parâmetro a percentagem de comprometimento tecidual deve ser previamente discutida entre os observadores. O método utilizado demonstrou ser rápido e eficiente.Idiopathic pulmonary fibrosis (cryptogenic fibrosing alveolitis is a progressive interstitial pulmonary disease of unknown etiology. Since Hamman's and Rich's (1944 reports, many studies have tried to find a histological marker for the correlation between prognosis and response to therapy.

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

    24-nor-ursodeoxycholic acid (norUDCA) is a novel therapeutic approach to cholestatic liver diseases. In mouse models of cholestasis, norUDCA induces basolateral multidrug resistance-associated proteins 4 (Mrp4) and 3 in hepatocytes, which provide alternative escape routes for bile acids accumulating during cholestasis but could also result in altered hepatic disposition of concomitantly administered substrate drugs. We used positron emission tomography imaging to study the influence of norUDCA on hepatic disposition of the model Mrp4 substrate [(18)F]ciprofloxacin in wild-type and Mdr2((-/-)) mice, a model of cholestasis. Animals underwent [(18)F]ciprofloxacin positron emission tomography at baseline and after norUDCA treatment. After norUDCA treatment, liver-to-blood area under the curve ratio of [(18)F]ciprofloxacin was significantly decreased compared to baseline, both in wild-type (-34.0 ± 2.1%) and Mdr2((-/-)) mice (-20.5 ± 6.0%). [(18)F]Ciprofloxacin uptake clearance from blood into liver was reduced by -17.1 ± 9.0% in wild-type and by -20.1 ± 7.3% in Mdr2((-/-)) mice. Real-time PCR analysis showed significant increases in hepatic Mrp4 and multidrug resistance-associated protein 3 mRNA after norUDCA. Transport experiments in organic anion transporting polypeptide (OATP)1B1-, OATP1B3-, and OATP2B1-transfected cells revealed weak transport of [(14)C]ciprofloxacin by OATP1B3 and OATP2B1 and no inhibition by norUDCA. In conclusion, our data suggest that changes in hepatic [(18)F]ciprofloxacin disposition in mice after norUDCA treatment were caused by induction of basolateral Mrp4 in hepatocytes.

    Full Text Available Congenital hepatic cyst is a rare and nonsymptomatic condition in infants and children. Its incidence is 2.5% in the postnatal life with a much lower incidence in the prenatal period. Incidental finding on antenatal imaging is the most common presentation. We present a case of a newborn in whom fetal ultrasound detected a cyst within the fetal liver. Postnatal imaging revealed a liver cyst in the right lobe of the liver, with no other intrahepatic structure affected. Liver function tests were abnormal, but the patient was asymptomatic. Posterior follow-up imaging showed a minor decrease in size. Management of congenital hepatic cyst is usually conservative, done with periodic ultrasound monitoring. However, surgical treatment is the mainstay of treatment when hydrops, progressive enlargement, hemorrhage, torsion, or compression of adjacent structures occurs. Malignant transformation can occur, but it is extremely rare. Partial or total removal of the cyst is the preferred treatment in neonates with a large lesion.

    Two flocks of 14,000 twenty-week-old turkey hens each experienced increased mortality due to hepatic lipidosis. Some hens showed signs of dyspnea and cyanosis before death. Necropsy revealed dark muscles and enlarged livers with pale areas and numerous hemorrhages. Petechial and ecchymotic hemorrhages were also found on the abdominal fat and epicardium. Lung congestion and edema were prominent. In the heart and blood vessels, the blood was uncoagulated. Mortality was elevated for 12 days and resulted in the death of 0.7% of the turkey hens in one flock and 1.7% in the other. Vitamin E administered in water at a dose of 25 IU per hen appeared to reduce mortality. The nutritional and environmental factors that may contribute to the development of hepatic lipidosis in turkeys are discussed.

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

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

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

    Full Text Available Relevance of hepatitis B due to the high incidence complexity of pathogenesis, ineffective treatment, severe consequences of the disease. Among combined lesions of the liver, special attention is paid to viral-alcoholic type. One of the mechanisms of chronic hepatitis of different etiology is violation of the functional activity of the autonomic nervous system. The aim of this work- to determine the dynamics of spectral indices of heart rate variability in patients with acute hepatitis B from chronic use of alcohol in hepatotoxic doses. Materials and methods. 133 patients with acute hepatitis B were under observation. Patients were divided into groups taking account the presence or absence of chronic use of alcohol in hepatotoxic doses and using the classification of alcohol consumption based on the frequency and dose of consumed alcohol. I group comprised 52 patients with chronic use of alcohol in the hepatotoxic doses, II group consisted of 81 patient without this factor. Heart rate variability was diagnosed using computer cardiointervalometry performed by electrocardiographic diagnostic system CardioLab-2000. 20 healthy individuals were in the control group. Results and discussion. Prodromal period in patients of the I group was longer (p0,05. However, only patients in group I had marked hemorrhagic manifestations (5,8 % and itching (7.7%. Average serum total bilirubin level was higher (p<0,05 in patients from the I group than in patients from II group. Functional state of autonomic nervous system in patients of both groups were decreased in acute period (vagotonia. Period of convalescence in patients from the I group was accompanied by more severe autonomic dysfunction in 33,6 % (p<0,05. Conclusions. 1. Acute hepatitis B in patients with chronic alcohol use in hepatotoxic doses is characterized by longer (p<0,05 prodrome, cholestatic (7,7% and hemorrhagic manifestations (5,8%, higher levels of hyperbilirubinemia (p<0,05, and during

This appears to be the only case in literature where primary hepatic lymphoma has shown contiguous localized intra- and extrahepatic tumor infiltration. A 67-year-old gentleman presented with history of significant loss of appetite and weight in 2 months with associated progressive painless cholestatic jaundice. Physical evaluation revealed normal vitals with pallor, deep icterus, scratch marks over the abdomen, generalized muscle wasting, grade II clubbing and a palpable non-tender liver with a globular, firm mass beneath the liver. He had a total serum bilirubin of 15.9 mg/dL and direct bilirubin of 9.24 mg/dL. His liver enzymes were moderately elevated with raised serum creatinine and dyselectrolytemia. Serology for enterohepatic viruses was negative. Contrast-enhanced magnetic resonance imaging (CEMRI) showed poorly enhancing multiple soft tissue masses in both lobes of liver with the largest mass involving, biliary confluence and porta hepatis causing right bile duct and portal vein encasement. The mass occupied the posterior right lobe and extended to the inferior surface of liver with contiguous invasion of the right renal upper pole cortex. The mass was associated with a retracted liver capsule in the involved segments and delayed enhancement, mimicking a cholangiocarcinoma.

    Substance P (SP) is involved in the proliferation of cholangiocytes in bile duct-ligated (BDL) mice and human cholangiocarcinoma growth by interacting with the neurokinin-1 receptor (NK-1R). To identify whether SP regulates liver fibrosis during cholestasis, wild-type or NK-1R knockout (NK-1R -/- ) mice that received BDL or sham surgery and multidrug resistance protein 2 knockout (Mdr2 -/- ) mice treated with either an NK-1R antagonist (L-733,060) or saline were used. Additionally, wild-type mice were treated with SP or saline intraperitoneally. In vivo, there was increased expression of tachykinin precursor 1 (coding SP) and NK-1R in both BDL and Mdr2 -/- mice compared to wild-type mice. Expression of tachykinin precursor 1 and NK-1R was significantly higher in liver samples from primary sclerosing cholangitis patients compared to healthy controls. Knockout of NK-1R decreased BDL-induced liver fibrosis, and treatment with L-733,060 resulted in decreased liver fibrosis in Mdr2 -/- mice, which was shown by decreased sirius red staining, fibrosis gene and protein expression, and reduced transforming growth factor-β1 levels in serum and cholangiocyte supernatants. Furthermore, we observed that reduced liver fibrosis in NK-1R -/- mice with BDL surgery or Mdr2 -/- mice treated with L-733,060 was associated with enhanced cellular senescence of hepatic stellate cells and decreased senescence of cholangiocytes. In vitro, L-733,060 inhibited SP-induced expression of fibrotic genes in hepatic stellate cells and cholangiocytes; treatment with L-733,060 partially reversed the SP-induced decrease of senescence gene expression in cultured hepatic stellate cells and the SP-induced increase of senescence-related gene expression in cultured cholangiocytes. Collectively, our results demonstrate the regulatory effects of the SP/NK-1R axis on liver fibrosis through changes in cellular senescence during cholestatic liver injury.

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

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

  11. Autoimmune hepatitis vs. pregnancy

    Directory of Open Access Journals (Sweden)

    Olga Adamczyk-Gruszka

    2017-07-01

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

    2016-08-01

    Alcoholic hepatitis (AH) causes great morbidity and mortality in the United States and throughout the world. Advances in therapy have proven difficult. In part, this reflects challenges in diagnosis, including the distinction between AH and acute-on-chronic liver failure. Liver biopsy is the best method to clarify the cause in circumstances whereby conflicting clinical data confound the diagnosis. All treatment of AH begins with abstinence from alcohol. All patients with AH should be given sufficient nutrition. Prednisolone has become the principal agent for treating patients with severe AH. Copyright © 2016 Elsevier Inc. All rights reserved.

    Five cases of iterative liver resections are presented, out of a total of 150 hepatectomies performed between 1.01.1995-1.01.1998. The resections were carried out for recurrent adenoma (one case), cholangiocarcinoma (two cases), hepatocellular carcinoma (one case), colo-rectal cancer metastasis (one case). Only cases with at least one major hepatic resection were included. Re-resections were more difficult than the primary resection due, first of all, to the modified vascular anatomy. Intraoperative ultrasound permitted localization of intrahepatic recurrences. Iterative liver resection appears to be the best therapeutical choice for patients with recurrent liver tumors.

    Autoimmune hepatitis is a chronic liver disease of unknown aetiology characterized by interface hepatitis, hypergammaglobulinaemia and circulating autoantibodies. In the last decade a number of advancements have been made in the field of clinical and basic research: the simplified diagnostic criteria, the complete response defined as normalization of transaminase levels, the molecular identification of the antigenic targets of anti-liver cytosol antibody type 1 and anti-soluble liver antigen, the detection of anti-actin antibodies, the description of de novo autoimmune hepatitis after liver transplantation for non-autoimmune liver diseases, the characterization of autoimmune hepatitis with overlapping features of primary biliary cirrhosis or primary sclerosing cholangitis, the preliminary experience with novel treatment strategies based on cyclosporine, mycophenolate mofetil and budesonide, the role played by "impaired" regulatory T cells and the development of novel animal models of autoimmune hepatitis.

    2009-06-01

    During the last decade patients with concomitant clinical, biochemical, immunoserological, and histological features of both autoimmune hepatitis (AIH) and primary biliary cirrhosis (PBC) were sporadically described, but definite diagnostic criteria and specific serological markers to support the diagnosis of AIH/PBC overlap syndrome (AIH/PBC OS) are still lacking. Clinical, biochemical, and histological features, autoantibody profile, and treatment response of 15 patients with coexistent hepatitic and cholestatic liver damage, all fulfilling strict diagnostic criteria for both AIH and PBC, were compared with those of 120 patients with pure PBC and 120 patients with pure AIH. At diagnosis, the AIH/PBC OS patients' median age was 51 years, similar to that of the PBC patients (52 years, P=NS), but significantly higher than that of the AIH patients (40 years, P=0.04). Anti-dsDNA antibodies were detected in 60% of AIH/PBC OS patients, but only in 4% of PBC patients and 26% of AIH patients (P<0.0001 and 0.01, respectively). Double positivity for antimitochondrial antibodies (AMA) and anti-dsDNA was present in 47% of those with AIH/PBC OS, but only in 2% of the pathological controls (P<0.0001; specificity: 98; 95% confidence interval (CI): 97-99.2; positive likelihood ratio: 28; 95% CI: 9.8-79.4). Combined therapy (ursodeoxycholic acid (UDCA) plus steroids) achieved biochemical response in 77% of AIH/PBC OS patients. Concomitant AMA/anti-dsDNA seropositivity can be considered the serological profile of AIH/PBC OS. The combination of UDCA and steroids is effective in achieving persistent biochemical amelioration in most AIH/PBC OS patients.

    Full Text Available Peracute infectious canine hepatitis (ICH was diagnosed in two young male dogs out of 56 dead canines presented for necropsy examination during the period of April 2009 to June 2010. These dogs were purebred, one- month old Alsatian and 5-month old Labrador. None of the dogs had received any vaccination or deworming treatment; both had died after illness lasting for six hours and twenty four hours respectively. The dogs had shown signs of depression, anorexia and fever. At necropsy, lymph nodes were swollen, edematous and congested; livers were enlarged, bright red and mottled with numerous small white foci. Petechial hemorrhages were seen in the mucosa. Excessive serosanguinous fluid was present in the abdominal cavities. Histologically, the most significant lesion was necrohemorrhagic hepatitis with single cell necrosis of hepatocytes, lacunose dilation of sinusoids filled with blood and numerous large, solid intranuclear inclusion bodies (IIBs in the hepatocytes and macrophages. Both eosinophilic and basophilic (amphophilic inclusions were seen. It has been observed that ICH is re-emerging in some endemic countries. Pet dogs should be regularly protected by effective vaccination.

FONTES DE DADOS: Bancos de dados MEDLINE (versão PubMed e Latin American and Caribbean Center on Health Sciences Information (LILACS, entre 1984 a 2009. Aplicou-se a combinação dos seguintes descritores: fibrose cística, estado nutricional, criança e adolescente - em inglês e português. SÍNTESE DOS DADOS: A fibrose cística é uma doença genética, de evolução crônica, progressiva e fatal. Resulta do defeito na proteína reguladora transmembrana que regula a condução de cloro e, consequentemente, o fluxo de sódio e água através da membrana apical das células epiteliais. Pacientes fibrocísticos são vulneráveis à desnutrição, que resulta do desequilíbrio entre ingestão alimentar, gasto e perdas energéticas. Novos conhecimentos sobre a fisiopatologia da doença, adquiridos nas últimas décadas, resultaram em mudanças significativas nas atuais recomendações energéticas e principalmente de lipídeos. A importância da nutrição no bem-estar e sobrevida dos fibrocísticos está bem estabelecida, assim como a associação entre a desnutrição e a deterioração da função pulmonar. Existem múltiplos fatores inter-relacionados que afetam o estado nutricional, tais como, mutação genética, insuficiência pancreática, ressecção intestinal, perda de sais e ácidos biliares, refluxo gastroesofágico, inflamação e infecções pulmonares, diabetes e condições emocionais. CONCLUSÕES: O monitoramento nutricional e o aconselhamento dietético são elementos chave no manejo de crianças e adolescentes com fibrose cística com o intuito de controlar a sintomatologia e a progressão da doença, proporcionando melhor qualidade de vida.OBJECTIVE: To review and discuss evidence on the nutritional status assessment and recommendations for

  5. Liver scintigraphy of fulminant hepatitis

    1980-01-01

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

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

    Mieli-Vergani, Giorgina; Vergani, Diego

    2002-08-01

    AIH, ASC, and de novo AIH after liver transplantation are childhood liver diseases of an autoimmune nature. The mode of presentation of AIH in childhood is variable, and the disease should be suspected and excluded in all children presenting with symptoms and signs of prolonged or severe acute liver disease. Although corticosteroids are effective in all types of childhood AIH, patients with LKM1 have a higher frequency of acute hepatic failure and relapse after corticosteroid withdrawal than do patients with ANA/SMA. ASC occurs commonly in the absence of inflammatory bowel disease, requires cholangiography for diagnosis, and improves during corticosteroid therapy. The development of AIH de novo in children who undergo liver transplantation for nonautoimmune liver disease may reflect interference with the maturation of T cells by immunosuppressive drugs.

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.

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

    BACKGROUND: Patients with hepatic encephalopathy may present with extrapyramidal symptoms and changes in basal ganglia. These changes are similar to those seen in patients with Parkinson's disease. Dopamine agents (such as bromocriptine and levodopa, used for patients with Parkinson's disease) have...... therefore been assessed as a potential treatment for patients with hepatic encephalopathy. OBJECTIVES: To evaluate the beneficial and harmful effects of dopamine agents versus placebo or no intervention for patients with hepatic encephalopathy. SEARCH METHODS: Trials were identified through the Cochrane...... hepatic encephalopathy that were published during 1979 to 1982 were included. Three trials assessed levodopa, and two trials assessed bromocriptine. The mean daily dose was 4 grams for levodopa and 15 grams for bromocriptine. The median duration of treatment was 14 days (range seven to 56 days). None...

    Liver histology is characterized by T cell infiltrating the parenchyma as reported in acute hepatitis. Recently in HAA it has been demonstrated intrahepatic  and blood lymphocytes with  T cell repertoire similar to that of confirmed viral acute hepatitis. The expanded T cell clones return to a normal distribution after response to immunosuppressive treatment, suggesting the antigen or T cell clearance. Therapeutic options are the same as acquired aplastic anemia.

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

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

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

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

    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

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

    Lemon, Stanley M; Walker, Christopher M

    2018-05-07

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

  13. Hepatic uptake of conjugated bile acids is mediated by both sodium taurocholate cotransporting polypeptide and organic anion transporting polypeptides and modulated by intestinal sensing of plasma bile acid levels in mice.

    The Na + -taurocholate cotransporting polypeptide (NTCP/SLC10A1) is believed to be pivotal for hepatic uptake of conjugated bile acids. However, plasma bile acid levels are normal in a subset of NTCP knockout mice and in mice treated with myrcludex B, a specific NTCP inhibitor. Here, we elucidated which transport proteins mediate the hepatic uptake of conjugated bile acids and demonstrated intestinal sensing of elevated bile acid levels in plasma in mice. Mice or healthy volunteers were treated with myrcludex B. Hepatic bile acid uptake kinetics were determined in wild-type (WT), organic anion transporting polypeptide (OATP) knockout mice (lacking Slco1a/1b isoforms), and human OATP1B1-transgenic mice. Effects of fibroblast growth factor 19 (FGF19) on hepatic transporter mRNA levels were assessed in rat hepatoma cells and in mice by peptide injection or adeno-associated virus-mediated overexpression. NTCP inhibition using myrcludex B had only moderate effects on bile acid kinetics in WT mice, but completely inhibited active transport of conjugated bile acid species in OATP knockout mice. Cholesterol 7α-hydroxylase Cyp7a1 expression was strongly down-regulated upon prolonged inhibition of hepatic uptake of conjugated bile acids. Fgf15 (mouse counterpart of FGF19) expression was induced in hypercholanemic OATP and NTCP knockout mice, as well as in myrcludex B-treated cholestatic mice, whereas plasma FGF19 was not induced in humans treated with myrcludex B. Fgf15/FGF19 expression was induced in polarized human enterocyte-models and mouse organoids by basolateral incubation with a high concentration (1 mM) of conjugated bile acids. NTCP and OATPs contribute to hepatic uptake of conjugated bile acids in mice, whereas the predominant uptake in humans is NTCP mediated. Enterocytes sense highly elevated levels of (conjugated) bile acids in the systemic circulation to induce FGF15/19, which modulates hepatic bile acid synthesis and uptake.

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

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

    Organ and region-selective intra-arterial chemotherapy have been used for more than two decades to treat malignant neoplasms in the extremities, head and neck region, pelvis, liver, and other areas. Substantial evidence of improved response to regional chemotherapy now exists, but there are stringent requirements for successful application of the regional technique. First, the chemotherapeutic agent employed must have appropriate pharmacokinetic and pharmacodynamic properties. Second, the drug must be reliably delivered to the tumor-bearing area. This typically requires an arteriographic assessment of the vascular supply of the tumor, followed by placement of a therapeutic catheter and confirmation that the ''watershed'' perfusion distribution from the catheter truly encompasses the tumor. Optimal catheter placement also minimizes perfusion of nontarget organs. Radionuclide perfusion imaging with technetium 99m-labeled particles, either microspheres or macroaggregates of albumin, has become the method of choice for making these assessments. Catheter placement itself is considered by many to represent a type of ''therapeutic'' intervention. However, once the catheter is in the hepatic artery the radionuclide perfusion technique can be used to assess adjunctive pharmacologic maneuvers designed to further exploit the regional approach to chemotherapy. This chapter presents the technetium Tc 99m macroaggregated albumin method for assessing catheter placement and the pharmacokinetic rationale for regional chemotherapy, and discusses two promising avenues for further intervention

Many associations have not been confirmed by prospective studies (as in the case of autoimmune hepatitis); other immune abnormalities, such as the emergence of non organ-specific autoantibodies and cryoglobulins, have been reported by many specific studies. To date, the link between HCV and autoreactivity is tentatively explained on the basis of sequence homologies shared by the HCV polyprotein and "self" proteins (such as CYP 2D6, target of anti-LKM1) (molecular mimicry mechanism); a second interpretation relies on the demonstration that the HCV - B lymphocyte interaction is able to induce a polyclonal B cell activation, an important cofactor for the development of clinically relevant B-lymphocyte autoimmune disorders. In this review we will focus on the major aspects of the autoimmune phenomena in HCV-infected patients, their clinical and therapeutical implications.

  18. [Prevention of virus hepatitis A to E].

    2011-03-01

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

    2015-12-14

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

    Hepatic steatosis is one of the most common liver disorders in the general population. The main cause of hepatic steatosis is nonalcoholic fatty liver disease (NAFLD), representing the hepatic component of the metabolic syndrome, which is characterized by type 2 diabetes, obesity, and dyslipidemia. Insulin resistance and excess adiposity are considered to play key roles in the pathogenesis of NAFLD. Although the risk factors for NAFLD are well established, the genetic basis of hepatic steatos...

    Full Text Available Estima-se que cerca de 3% da população mundial esteja infectada pelo vírus da hepatite C. Todos os que receberam transfusão de sangue ou seus componentes e os usuários de drogas podem estar infectados. Procedimentos odontológicos, médicos, tatuagem ou acupuntura também constituem fatores de risco. A infecção se cronifica em até 85% dos indivíduos, com evolução assintomática durante anos ou décadas e apresentação clínica variada. Para o diagnóstico, a determinação do anti-VHC revela-se muito sensível e a confirmação se faz pela determinação do RNA-VHC no sangue; o estadiamento da doença e a avaliação da atividade inflamatória pela biópsia hepática. O tratamento objetiva deter a progressão da doença hepática através da inibição da replicação viral. Devido à baixa eficácia terapêutica aliada a importantes efeitos colaterais do interferon e da ribavirina, esses medicamentos encontram indicações e contra-indicações específicas. Vários fatores preditivos de resposta ao tratamento, principalmente a carga viral e o genótipo do VHC, mostram-se úteis na avaliação dos pacientes.It has been estimated that 3% of the world population is infected with the hepatitis C virus. Those who are blood product recipients or have been illicit drug users are at risk. Dental and medical procedures as well as tattooing and acupuncture are also risk factors. Chronic infection occurs in up to 85% of infected cases but they may remain without symptoms during years or even decades, and clinical presentation varies. Determination of anti-HCV in sera is a fairly sensitive tool for the diagnosis, and confirmation requires the identification of HCV-RNA. Staging of the liver disease as well as definition of its present activity can be graded by liver biopsy. The aim of treatment is to stop the progression of the hepatic disease by inhibiting viral replication. Due to the low therapeutic efficacy combined with important side

  15. Biliary Stricture Following Hepatic Resection

    Directory of Open Access Journals (Sweden)

    Jeffrey B. Matthews

    1991-01-01

    Full Text Available Anatomic distortion and displacement of hilar structures due to liver lobe atrophy and hypertrophy occasionally complicates the surgical approach for biliary stricture repair. Benign biliary stricture following hepatic resection deserves special consideration in this regard because the inevitable hypertrophy of the residual liver causes marked rotation and displacement of the hepatic hilum that if not anticipated may render exposure for repair difficult and dangerous. Three patients with biliary stricture after hepatectomy illustrate the influence of hepatic regeneration on attempts at subsequent stricture repair. Following left hepatectomy, hypertrophy of the right and caudate lobes causes an anteromedial rotation and displacement of the portal structures. After right hepatectomy, the rotation is posterolateral, and a thoracoabdominal approach may be necessary for adequate exposure. Radiographs obtained in the standard anteroposterior projection may be deceptive, and lateral views are recommended to aid in operative planning.

  16. Viral hepatitis in the elderly.

    Carrion, Andres F; Martin, Paul

    2012-05-01

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

    2016-01-01

    The main function of erythropoietin (EPO) is to maintain red blood cell mass, but in recent years, increasing evidence has suggested a wider biological role not solely related to erythropoiesis, e.g. angiogenesis and tissue protection. EPO is produced in the liver during fetal life, but the main...... production shifts to the kidney after birth. The liver maintains a production capacity of up to 10% of the total EPO synthesis in healthy controls, but can be up-regulated to 90-100%. However, the hepatic EPO synthesis has been shown not to be adequate for correction of anemia in the absence of renal......, which lead to arterial hypotension, hepatic nephropathy and anemia. An increase in EPO due to renal hypoperfusion, hypoxia and anemia or an EPO-mediated hepato-protective and regenerative mechanism is plausible. However, poor hepatic synthesis capacity, a decreasing co-factor level and inflammatory...

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

    1975-10-01

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

    2015-06-28

    Although only a single serotype of hepatitis E virus (HEV), the causative agent of hepatitis E, has been identified, there is great genetic variation among the different HEV isolates reported. There are at least four major recognized genotypes of HEV: genotypes 1 and 2 are mainly restricted to humans and linked to epidemic outbreaks in nonindustrialized countries, whereas genotypes 3 and 4 are zoonotic in both developing and industrialized countries. Besides human strains, genotype 3 and 4 strains of HEV have been genetically characterized from swine, sika deer, mongooses, sheep, and rabbits. Currently, there are approximately 11,000 human and animal sequences of HEV available at the International Nucleotide Sequence Database Collaboration. HEV is the major cause of waterborne outbreaks of hepatitis in areas of poor sanitation. Additionally, it is responsible for sporadic cases of viral hepatitis in not only endemic but industrialized countries as well. Transmission of HEV occurs predominantly by the fecal-oral route, although parenteral and perinatal routes have been reported. HEV infection develops in most individuals as a self-limiting, acute, icteric hepatitis; with mortality rates around 1%. However, some affected individuals will develop fulminant hepatic failure, a serious condition that is frequently fatal without a liver transplant. This complication is particularly common when the infection occurs in pregnant women, where mortality rates rise dramatically to up to 25%. Among the preventive measures available to avoid HEV infection, two separate subunit vaccines containing recombinant truncated capsid proteins of HEV have been shown to be highly effective in the prevention of disease. One of them, HEV 239, was approved in China, and its commercialization by Innovax began in November 2012 under the name Hecolin(®).

  8. Adipokines and Hepatic Insulin Resistance

    Science.gov (United States)

    Hassan, Waseem

    2013-01-01

    Obesity is a major risk factor for insulin resistance and type 2 diabetes. Adipose tissue is now considered to be an active endocrine organ that secretes various adipokines such as adiponectin, leptin, resistin, tumour necrosis factor-α, and interleukin-6. Recent studies have shown that these factors might provide a molecular link between increased adiposity and impaired insulin sensitivity. Since hepatic insulin resistance plays the key role in the whole body insulin resistance, clarification of the regulatory processes about hepatic insulin resistance by adipokines in rodents and human would seem essential in order to understand the mechanism of type 2 diabetes and for developing novel therapeutic strategies to treat it.

    In this study, serological screening for celiac disease (CD) was performed in patients with autoimmune cholestasis to define the prevalence of such an association and to evaluate the impact of gluten withdrawal on liver disease associated with gluten sensitive enteropathy. Immunoglobulin A endomysial, human and guinea pig tissue transglutaminase antibodies, and immunoglobulin A and G gliadin antibodies were sought in 255 patients with primary biliary cirrhosis, autoimmune cholangitis, and primary sclerosing cholangitis. Immunoglobulin A endomysial and human tissue transglutaminase antibodies were positive in nine patients (seven primary biliary cirrhosis, one autoimmune cholangitis, and one primary sclerosing cholangitis), whose duodenal biopsy results showed villous atrophy consistent with CD. Two of these patients had a malabsorption syndrome, and one had iron-deficiency anemia. Clinical and biochemical signs of cholestasis did not improve after gluten withdrawal in the three patients with severe liver disease. A longer follow-up of the six celiac patients with mild liver damage is needed to clarify whether gluten restriction can contribute to slow down the progression of liver disease. The high prevalence of CD (3.5%) in autoimmune cholestasis suggests that serological screening for CD should be routinely performed in such patients by immunoglobulin A endomysial or human tissue transglutaminase antibodies.

    2006-06-01

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

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

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

    Full Text Available Since Hippocrates that neuropsychiatric illness secondary to liver disease fascinates physicians, but only in the XIX century Marcel Nencki and Ivan Pavlov suggested the relation between high concentrations of ammonia and Hepatic Encephalopathy (HE. The reaction of ammonia and glutamate (origins glutamine, “the Trojan Horse of neurotoxicity of ammonia continues to be the main responsible for the neurologic lesions, recently confirmed by neurochemistry and neuroimagiology studies. Glutamine starts the inflammatory reaction at the central nervous sys- tem but other important actors seem to be manganese and the neurotransmitters systems of GABA and endocanabinoids. Nowadays there are three different etiologic big groups for HE: type A associated with acute liver failure; type B associated with portosystemic bypass; and type C associated with cirrhosis of the liver. The staging of HE is still based on classic West Haven system, but a latent Grade 0 was introduced (the so called minimal HE; remaining the aggra- vating HE from Grade 1 (subtle changes at clinical examination to Grade 4 (coma. In this work a bibliographic review was made on 30 of the most pertinent and recent papers, focusing in psychopathology, physiopathology, etiology and staging of this clinical entity transversal to Psychiatry and Gastroenterology. Alterations are described in vigility and conscience like temporal, spatial and personal disorientation. Attention, concentration and memory are impaired very early, on latent phase and can be accessed through neuropsychological tests. Mood oscillates between euphoric and depressive. Personality changes begin obviously and abruptly or in a subtle and insidious way. There can be changes in perception like visual hallucinations or even of acoustic-verbal. The thought disorders can be of delusional type, paranoid, systematized or not, but also monothematic ala Capgras Syndrome. Speech can be accelerated, slowed down or completely in

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

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

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