    The aims of this study were to determine the frequency of bleeding complications following dental procedures in patients with known or suspected chronic liver disease and whether international normalized ratio (INR) determination could aid in predicting bleeding complications in these patients. We identified 90 patients (mean age: 51 ± 9 years) in this retrospective chart review. Sixty-nine patients had a known history of chronic liver disease and 21 had suspected chronic liver disease. Descriptive statistics were determined. Independent sample t-test and one-way variance test were utilized for continuous variables and chi-square test for dichotomous variables. The mean INR value for all patients was 1.2 ± 0.3. The INR value was significantly associated with the diagnosis of liver cirrhosis, the diagnoses of Hepatitis B and C together, the presence of ascites alone, and the number of clinical signs and symptoms (i.e. ascites, jaundice and encephalopathy) present. Nine patients with INR values between 1.5 and 2 underwent invasive dental procedures without postoperative bleeding complications. There were no episodes of postoperative bleeding in patients. The findings suggest that clinicians should not rely solely on an INR value to predict post-procedure bleeding in patients with liver disease. © 2012 John Wiley & Sons A/S.

    Full Text Available Nonalcoholic fatty liver disease (NAFLD has become a serious public health problem worldwide; however, the availability of information on the prevalence of NAFLD in the general pediatric population is still limited. The primary aim of this study was to reveal the prevalence and correlates of suspected NAFLD in Chinese children at the national level. Data from the China Health and Nutrition Surveys (CHNS was used. Weight, height, waist circumference (WC, blood pressure (BP were measured for children aged 7–18 years. Blood samples were collected and analyzed. Children were classified as having suspected NAFLD if common causes of liver disease were excluded, and serum alanine aminotransferase (ALT values were above the established thresholds (>22.1 IU/L for girls and >25.8 IU/L for boys. A percentage of 9.03% (75 out of 831 of Chinese children was found to have suspected NAFLD. Overweight and obesity according to BMI percentiles, abdominal obesity, hyperuricemia (uric acid (UA > 327 μmol/L, and elevated total cholesterol (TC were all detected as the correlates of childhood suspected NAFLD when adjusting for other factors. Our study revealed the prevalence of suspected NAFLD in general Chinese children at the national level for the first time. Our findings indicate that suspected NAFLD in children is associated with increasing childhood morbidities, further studies are needed to better understand the prevalence of childhood NAFLD and its correlates, and large-scale programs should be launched to screen NAFLD in the pediatric population in China.

    Steatosis in patients with nonalcoholic fatty liver disease (NAFLD) is often benign, but may progress to fibrosis. The accurate diagnosis of hepatic steatosis is therefore important for clinical decision-making and prognostic assessments. The controlled attenuation parameter (CAP), a noninvasive measurement obtained with Fibro-Scan, has been developed for liver steatosis assessment. CAP performs poorly in patients with high BMI. The XL probe was initially developed for measuring liver stiffness in overweight patients. We assessed the diagnostic value of CAP in candidates for bariatric surgery with suspected NAFLD examined with the XL probe. For the retrospective group, raw ultrasonic radiofrequency signals were stored prospectively in the Fibro-Scan examination file for offline CAP calculation in 194 consecutive obese patients undergoing liver stiffness measurement in the 15 days before liver biopsy. For the prospective group, CAP was calculated automatically and prospectively from the XL probe in 123 obese patients. In the retrospective group, the diagnostic accuracy of CAP was satisfactory for differentiating S3 from S0-S1-S2 (0.79±0.03; 95% confidence interval: 0.71-0.84) and S3 from S0 (0.85±0.05; 95% confidence interval: 0.73-0.92). The Obuchowski measure demonstrated a very good discriminatory performance: 0.87±0.02 in the retrospective group and 0.91±0.02 in the prospective group. CAP calculations from XL probe measurements efficiently detected severe steatosis in morbidly obese patients with suspected NAFLD. However, the cutoff values should now be confirmed in a larger prospective cohort.

    Background Screening overweight and obese children for non-alcoholic fatty liver disease (NAFLD) is recommended by paediatric and endocrinology societies. However, gastroenterology societies have called for more data before making a formal recommendation. Aim To determine whether the detection of suspected NAFLD in overweight and obese children through screening in primary care and referral to paediatric gastroenterology resulted in a correct diagnosis of NAFLD. Methods Information generated in the clinical evaluation of 347 children identified with suspected NAFLD through screening in primary care and referral to paediatric gastroenterology was captured prospectively. Diagnostic outcomes were reported. The diagnostic performance of two times the upper limit of normal (ULN) for alanine aminotransferase (ALT) was assessed. Results Non-alcoholic fatty liver disease was diagnosed in 55% of children identified by screening and referral. Liver disease other than NAFLD was present in 18% of those referred. Autoimmune hepatitis was the most common alternative diagnosis. Children with NAFLD had significantly (P gastroenterology has the potential to identify clinically relevant liver pathology. Consensus is needed on how to value the risk and rewards of screening and referral, to identify children with liver disease in the most appropriate manner. PMID:24117728

  5. Non-invasive diagnostic assessment tools for the detection of liver fibrosis in patients with suspected alcohol-related liver disease: a systematic review and economic evaluation.

    Excessive alcohol consumption may lead to the development of alcohol-related liver disease (ALD). Liver biopsy may be used in patients with suspected ALD to confirm the diagnosis, exclude other or additional liver pathologies, and provide accurate staging of the degree of liver injury in order to enable the prediction of prognosis and inform treatment decisions. However, as it is an invasive procedure that carries the risk of morbidity and mortality, current UK guidance recommends that biopsy is not required to confirm the diagnosis in patients with a high clinical suspicion of ALD in whom blood tests have excluded other causes of liver disease, unless it is necessary to confirm a diagnosis of acute alcoholic hepatitis in order to inform specific treatment decisions. To evaluate the diagnostic accuracy, cost-effectiveness, and effect on patient outcomes of four non-invasive tests for liver fibrosis [the Enhanced Liver Fibrosis (ELF™) test (Siemens Healthcare Diagnostic Inc., Tarrytown, NY, USA), FibroTest (BioPredictive, Paris, France), FibroMAX (BioPredictive, Paris, France) and transient elastography (FibroScan(®); produced by EchoSens, Paris, France and distributed in the UK by Artemis Medical Ltd, Kent, UK)] in patients suspected of having ALD. A systematic review was undertaken to identify studies reporting the diagnostic and prognostic accuracy of the ELF test, FibroTest, FibroMAX, and FibroScan for the identification of liver fibrosis and associated conditions in patients with suspected ALD. The following databases were searched in January 2010: MEDLINE (from 1950 to January 2010), MEDLINE In-Process & Other Non-Indexed Citations (from 1950 to January 2010), EMBASE (from 1980 to January 2010), Cochrane Database of Systematic Reviews (from 1996 to January 2010), Cochrane Central Register of Controlled Trials (from 1898 to January 2010), Cochrane Methodology Register (from 1904 to January 2010), Database of Abstracts of Reviews of Effects (from 1995 to

    Serai, Suraj D; Dillman, Jonathan R; Trout, Andrew T

    2017-03-01

    Purpose To compare two-dimensional (2D) gradient-recalled echo (GRE) and 2D spin-echo (SE) echo-planar imaging (EPI) magnetic resonance (MR) elastography for measurement of hepatic stiffness in pediatric and young adult patients suspected of having liver disease. Materials and Methods In this institutional review board-approved, HIPAA-compliant study, 58 patients underwent both 2D GRE and 2D SE-EPI MR elastography at 1.5 T during separate breath holds. Liver stiffness (mean of means; in kilopascals) was measured by five blinded reviewers. Pooled mean liver stiffness and region-of-interest (ROI) size were compared by using paired t tests. Intraclass correlation coefficients (ICCs) were used to assess agreement between techniques. Respiratory motion artifacts were compared across sequences by using the Fisher exact test. Results Mean patient age was 14.7 years ± 5.2 (standard deviation; age range, 0.7-20.5 years), and 55.2% (32 of 58) of patients were male. Mean liver stiffness was 2.92 kPa ± 1.29 measured at GRE MR elastography and 2.76 kPa ± 1.39 at SE-EPI MR elastography (n = 290; P = .15). Mean ROI sizes were 8495 mm 2 ± 4482 for 2D GRE MR elastography and 15 176 mm 2 ± 7609 for 2D SE-EPI MR elastography (n = 290; P range, 0.91-0.95). Moderate or severe breathing artifacts were observed on 27.5% (16 of 58) of 2D GRE images versus 0% 2D SE-EPI images (P < .001). Conclusion There is excellent agreement on measured hepatic stiffness between 2D GRE and 2D SE-EPI MR elastography across multiple reviewers. SE-EPI MR elastography allowed for stiffness measurement across larger areas of the liver and can be performed in a single breath hold. © RSNA, 2016.

    Liver diseases in pregnancy may be categorized into liver disorders that occur only in the setting of pregnancy and liver diseases that occur coincidentally with pregnancy. Hyperemesis gravidarum, preeclampsia/eclampsia, syndrome of hemolysis, elevated liver tests and low platelets (HELLP), acute fatty liver of pregnancy, and intrahepatic cholestasis of pregnancy are pregnancy-specific disorders that may cause elevations in liver tests and hepatic dysfunction. Chronic liver diseases, including cholestatic liver disease, autoimmune hepatitis, Wilson disease, and viral hepatitis may also be seen in pregnancy. Management of liver disease in pregnancy requires collaboration between obstetricians and gastroenterologists/hepatologists. Treatment of pregnancy-specific liver disorders usually involves delivery of the fetus and supportive care, whereas management of chronic liver disease in pregnancy is directed toward optimizing control of the liver disorder. Cirrhosis in the setting of pregnancy is less commonly observed but offers unique challenges for patients and practitioners. This article reviews the epidemiology, pathophysiology, diagnosis, and management of liver diseases seen in pregnancy.

    Coffee is the most popular beverage in the world. Consumption of coffee has been shown to benefit health in general, and liver health in particular. This article reviews the effects of coffee intake on development and progression of liver disease due to various causes. We also describe the putative mechanisms by which coffee exerts the protective effect. The clinical evidence of benefit of coffee consumption in Hepatitis B and C, as well as nonalcoholic fatty liver disease and alcoholic liver disease, has also been presented. Coffee consumption is associated with improvement in liver enzymes (ALT, AST, and GGTP), especially in individuals with risk for liver disease. Coffee intake more than 2 cups per day in patients with preexisting liver disease has been shown to be associated with lower incidence of fibrosis and cirrhosis, lower hepatocellular carcinoma rates, as well as decreased mortality.

The visually assessed presence or absence of contrast agent for each of five anatomical regions in randomly reviewed time-series was summarized on a four grade scale for each patient. The scores, including a total visual score, were related to the histo-pathological findings, the quantitative contrast agent uptake parameters, expressed as K Hep or LSC-N, and blood tests. No relationship between the fibrosis grade or contrast uptake parameters could be established. A negative correlation between the visual assessment and alkaline phosphatase (ALP) was found. Comparing a sub-group of cholestatic patients with fibrosis score and Gd-EOB-DTPA dynamic parameters did not add any additional significant correlation. No correlation between visually assessed biliary excretion of Gd-EOB-DTPA and histo-pathological or contrast uptake

    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.

  2. Cytokines and Liver Diseases

    Directory of Open Access Journals (Sweden)

    Herbert Tilg

    2001-01-01

    Full Text Available Cytokines are pleiotropic peptides produced by virtually every nucleated cell in the body. In most tissues, including the liver, constitutive production of cytokines is absent or minimal. There is increasing evidence that several cytokines mediate hepatic inflammation, apoptosis and necrosis of liver cells, cholestasis and fibrosis. Interestingly, the same mediators also mediate the regeneration of liver tissue after injury. Among the various cytokines, the proinflammatory cytokine tumour necrosis factor-alpha (TNF-a has emerged as a key factor in various aspects of liver disease, such as cachexia and/or cholestasis. Thus, antagonism of TNF-a and other injury-related cytokines in liver diseases merits evaluation as a treatment of these diseases. However, because the same cytokines are also necessary for the regeneration of the tissue after the liver has been injured, inhibition of these mediators might impair hepatic recovery. The near future will bring the exiting clinical challenge of testing new anticytokine strategies in various liver diseases.

    Autoimmune liver disease (ALD) includes a spectrum of diseases which comprises both cholestatic and hepatitic forms: autoimmune hepatitis (AIH), primary biliary cirrhosis (PBC), primary sclerosing cholangitis (PSC) and the so called "overlap" syndromes where hepatitic and cholestatic damage coexists. All these diseases are characterized by an extremely high heterogeneity of presentation, varying from asymptomatic, acute (as in a subset of AIH) or chronic (with aspecific symptoms such as fatigue and myalgia in AIH or fatigue and pruritus in PBC and PSC). The detection and characterization of non organ specific autoantibodies plays a major role in the diagnostic approach of autoimmune liver disease; anti nuclear reactivities (ANA) and anti smooth muscle antibodies (SMA) mark type 1 AIH, liver kidney microsomal antibody type 1 (LKM1) and liver cytosol type 1 (LC1) are the serological markers of type 2 AIH; antimitochondrial antibodies (AMA) are associated with PBC, while no specific marker is found in PSC, since anticytoplasmic neutrophil antibodies with perinuclear pattern (atypical p-ANCA or p-ANNA) are also detected in a substantial proportion of type 1 AIH cases. Treatment options rely on immunosoppressive therapy (steroids and azathioprine) in AIH and on ursodeoxycholic acid in cholestatic conditions; in all these diseases liver transplantation remains the only therapeutical approach for the end stage of liver disease.

  5. The Role of Liver Biopsy in the Management of Patients with Liver Disease

    Directory of Open Access Journals (Sweden)

    2003-01-01

    Full Text Available The role of liver biopsy in the diagnosis and management of liver disease is a controversial issue even among hepatologists. Although most causes of elevated liver enzymes can be determined, or at least suspected, on the basis of a careful history and laboratory tests, histological assessment remains the gold standard for most liver diseases. Histological evaluation can either confirm or refute clinical diagnoses and can provide information about the severity and stage of disease. Occasionally, the liver biopsy also provides an additional diagnosis. The spectrum of nonalcoholic fatty liver disease accounts for a substantial proportion of cases of chronically elevated liver enzymes and can be reliably diagnosed only by liver biopsy. Prognostic information can be obtained in patients with this disorder, as well as in those with alcoholic liver disease and viral hepatitis, and liver biopsy can be used as a guide to their management.

    Full Text Available Toll-like receptor (TLR signaling pathways are strictly coordinated by several mechanisms to regulate adequate innate immune responses. Recent lines of evidence indicate that the suppressor of cytokine signaling (SOCS family proteins, originally identified as negative-feedback regulators in cytokine signaling, are involved in the regulation of TLR-mediated immune responses. SOCS1, a member of SOCS family, is strongly induced upon TLR stimulation. Cells lacking SOCS1 are hyperresponsive to TLR stimulation. Thus, SOCS1 is an important regulator for both cytokine and TLR-induced responses. As an immune organ, the liver contains various types of immune cells such as T cells, NK cells, NKT cells, and Kupffer cells and is continuously challenged with gut-derived bacterial and dietary antigens. SOCS1 may be implicated in pathophysiology of the liver. The studies using SOCS1-deficient mice revealed that endogenous SOCS1 is critical for the prevention of liver diseases such as hepatitis, cirrhosis, and cancers. Recent studies on humans suggest that SOCS1 is involved in the development of various liver disorders in humans. Thus, SOCS1 and other SOCS proteins are potential targets for the therapy of human liver diseases.

    The results of liver scans performed with sup(99m)Tc-sulphur colloid in 169 patients suffering from diffuse liver diseases and in 48 normal controls were evaluated. The patients with reactive hepatitis, acute hepatitis, chronic persistent hepatitis, fatty liver and fibrosis of the liver show only minimal deviations from the scintigraphic pattern. On the contrary, highly increased colloid uptake in the spleen is found in cases of chronic aggressive hepatitis, whilst the intrahepatic distribution of the colloid is approximately normal. In cases of liver cirrhosis, increased colloid uptake is found in the left lobe of the liver as well as in the spleen and in the bone marrow. Either normal findings or cirrhosis-like changes of the colloid distribution are observed in patients with alcoholic hepatitis. (orig.) [de

    Liver diseases in the elderly have aroused less interest than diseases of other organs, since the liver plays a limited role in aging. There are no specific liver diseases of old age, but age-related anatomical and functional modifications of the liver cause changes in the frequency and clinical behavior of some liver diseases compared with those in younger patients. This review discusses the most important features of liver function in the healthy elderly population, as well as the features of the most prevalent liver diseases in this age group, especially the diagnostic approach to the most common liver problems in the elderly: asymptomatic elevation of serum transaminases and jaundice.

    OBJECTIVE: Polycystic liver disease (PLD) is a rare, hereditary, benign disorder. Hepatic failure is uncommon and symptoms are caused by mass effects leading to abdominal distension and pain. Liver transplantation (LTX) offers fully curative treatment, but there is still some controversy about...... whether it is a relevant modality considering the absence of liver failure, relative organ shortage, perioperative risks and lifelong immunosuppression. The purpose of this study was to review our experience of LTX for PLD and to compare the survival with the overall survival of patients who underwent LTX...... from 1992 to 2005. MATERIAL AND METHODS: A retrospective study of the journals of 440 patients, who underwent 506 LTXs between 1992 and 2005, showed that 14 patients underwent LTX for PLD. All patients had normal liver function. Three were receiving haemodialysis and thus underwent combined liver...

Labs revealed total bilirubin of 1.5 mg/dl, hypoalbuminaemia 3.0 gm/dl and prolonged prothrombin time of 14.8 sec. Computed Tomography of the abdomen and pelvis with contrast showed multiple hepatic cysts with the largest cyst occupying the right abdomen, measuring 20.6 cm (Panel A and). This cyst had predominantly fluid attenuation, but also contained several septations. The patient underwent laparoscopic fenestration of the large hepatic cyst with hepatic cyst wall biopsy. Pathology revealed blood without malignant cells. The patient tolerated the procedure well with improvement of his abdominal pain and normalization of his liver function tests and coagulation profile.

    Gaucher disease (GD), one of the most prevalent lysosomal storage diseases, is associated with glucocerebroside accumulation in cells of the monocyte-macrophage system in various organs, including the liver. Evaluating and managing liver disease in patients with Gaucher disease may be challenging. While hepatic involvement is common in Gaucher disease, its severity, and clinical significance span a wide spectrum, ranging from sub-clinical involvement to liver cirrhosis with its associated complications including portal hypertension. Apart from liver involvement in Gaucher disease, patients with may also suffer from other comorbidities involving the liver. That Gaucher disease itself can mimic hepatic lesions, affect laboratory tests used to characterize liver disease, and may be associated with non-cirrhotic portal hypertension, complicates the diagnostic approach even more. Better understanding of liver involvement in Gaucher disease can spare patients unnecessary invasive testing, and assist physicians in decision making when evaluating patients with Gaucher disease suspected for significant liver disease. This review describes the various clinical manifestations, laboratory and imaging abnormalities that may be encountered when following patients with Gaucher disease for liver involvement. The mechanism for liver disease are discussed, as well as the possible hepato-protective effect of glucocerebroside, and the a diagnostic and treatment approaches. Copyright © 2016 Elsevier Inc.

    Fibropolycystic liver diseases are a group of associated congenital disorders that present most often in childhood. These disorders include congenital hepatic fibrosis, biliary hamartomas, autosomal dominant polycystic liver disease, choledochal cysts and Caroli disease. We present a discussion and illustrations of the embryology, genetics, anatomy, pathology, imaging approach and key imaging features that distinguish fibropolycystic liver disease in children. The pathogenesis of these disorders is believed to be abnormal development of the embryonic ductal plates, which ultimately form the liver and biliary systems. An understanding of the abnormal embryogenesis helps to explain the characteristic imaging features of these disorders. (orig.)

    Objectives The objective was to evaluate the safety and diagnostic utility of percutaneous ultrasound-guided cholecystocentesis (PUC) in cats with suspected hepatobiliary disease. Methods Medical records of 83 cats with suspected hepatobiliary disease that underwent PUC were retrospectively reviewed. Results At the time of PUC, at least one additional procedure was performed in 79/83 cats, including hepatic aspiration and/or biopsy (n = 75) and splenic aspiration (n = 18). Complications were noted in 14/83 cases, including increased abdominal fluid (n = 11), needle-tip occlusion (n = 1), failed first attempt to penetrate the gall bladder wall (n = 1) and pneumoperitoneum (n = 1). There were no reports of gall bladder rupture, bile peritonitis or hypotension necessitating treatment with vasopressor medication. Blood products were administered to 7/83 (8%) cats. Seventy-two cats (87%) survived to discharge. Of the cats that were euthanized (9/83) or died (2/83), none were reported as a definitive consequence of PUC. Bacteria were identified cytologically in 10/71 samples (14%); all 10 had a positive aerobic bacterial culture. Bile culture was positive in 11/80 samples (14%). Of the cases with a positive bile culture, cytological description of bacteria corresponded to the organism cultured in fewer than 50% of cases. The most common cytologic diagnosis was hepatic lipidosis (49/66). The most common histopathologic diagnosis was cholangitis (10/21). Conclusions and relevance PUC was safe in this group of cats with suspected hepatobiliary disease. Complications were likely associated with ancillary procedures performed at the time of PUC. Bile analysis yielded an abnormal result in nearly one-third of cats with suspected hepatobiliary disease. Complete agreement between bile cytology and culture was lacking. Further evaluation of the correlation between bile cytology and bile culture is warranted.

    A 68-year-old man diagnosed with cT3N2 adenocarcinoma of the rectum presented with a synchronous solitary liver metastasis on CT scan. Neoadjuvant chemoradiotherapy was started to downstage the primary tumour. Resection of the rectal tumour followed 3 months after the last radiotherapy session and primary resection of the isolated liver lesion was performed in the intervening period. Histopathological assessment of the liver lesion, however, showed no malignancy, but did reveal a necrotic infection due to Enterobius vermicularis. This parasite is frequently found in the intestines, but only rarely infects the liver. The patient was subsequently treated with the anthelmintic drug mebendazole 100 mg once a week for 2 weeks. Histopathological assessment of the rectal specimen showed complete regression after neoadjuvant chemoradiotherapy without evidence of remaining E. vermicularis, suggesting pinworm eradication. The patient recovered promptly after both surgical procedures. PMID:26546623

    2008-04-01

    Incipient Alzheimer's disease (AD) is frequently suspected by neurologists and psychiatrists, but diagnosis is difficult to establish. The aim of this report was to analyse to what extent suspicion is confirmed by a comprehensive neuropsychological examination intended to distinguish different types of dementia. Descriptive data analysis was used for investigating the differential diagnoses of 47 outpatients with suspected AD referred to a department of neuropsychology by physicians in private practice. Data analysis was based upon the NINCDS-ADRDA diagnostic criteria of AD. Only 38% of the outpatients examined with suspected AD met the NINCDS-ADRDA diagnostic criteria for AD or mixed dementia from a neuropsychological point of view, whereas 22% met criteria for other types of dementia. The remaining patients met criteria for distinct differential diagnoses (23%) or lacked pathological findings in neuropsychological functions (17%). Neuropsychology is an essential part in the differential diagnosis of mild to moderate dementias. It can aid in differential therapeutic considerations concerning the treatment of dementia, for example in selecting appropriate treatments or avoiding expensive but inappropriate ones.

  11. HEMOSTATIC DISORDERS IN LIVER DISEASES

    Directory of Open Access Journals (Sweden)

    A. F. Minov

    2010-01-01

    Full Text Available The liver is an essential player in the pathway of coagulation in both primary and secondary hemostasis as it is the site of synthesis of all coagulation factors and their inhibitors. Liver diseases are associated with complex changes in coagulation and the delicate balance between pro and antithrombotic factors is preserved but reset to a lower level. There is growing evidence that portal and hepatic vein thrombosis is cause of disease progression in cirrhotic patients and worsens hemostatic abnormalities. These hemostatic abnormalities do not always lead to spontaneous bleeding, which may be triggered only by additional factors, such as infections. Usually therapy for coagulation disorders in liver disease is needed only during bleeding or before invasive procedures. In patients with end stage liver disease liver transplantation is the only treatment available, which can restore normal hemostasis, and correct genetic clotting defects. During liver transplantation hemorrhage may occur due to the pre-existing hypocoagulable state, the collateral circulation caused by portal hypertension and increased fibrinolysis.

    2008-06-07

    Liver disorders with a likely autoimmune pathogenesis in childhood include autoimmune hepatitis (AIH), autoimmune sclerosing cholangitis (ASC), and de novo AIH after liver transplantation. AIH is divided into two subtypes according to seropositivity for smooth muscle and/or antinuclear antibody (SMA/ANA, type 1) or liver kidney microsomal antibody (LKM1, type 2). There is a female predominance in both. LKM1 positive patients tend to present more acutely, at a younger age, and commonly have partial IgA deficiency, while duration of symptoms before diagnosis, clinical signs, family history of autoimmunity, presence of associated autoimmune disorders, response to treatment, and long-term prognosis are similar in both groups. The most common type of paediatric sclerosing cholangitis is ASC. The clinical, biochemical, immunological, and histological presentation of ASC is often indistinguishable from that of AIH type 1. In both, there are high IgG, non-organ specific autoantibodies, and interface hepatitis. Diagnosis is made by cholangiography. Children with ASC respond to immunosuppression satisfactorily and similarly to AIH in respect to remission and relapse rates, times to normalization of biochemical parameters, and decreased inflammatory activity on follow up liver biopsies. However, the cholangiopathy can progress. There may be evolution from AIH to ASC over the years, despite treatment. De novo AIH after liver transplantation affects patients not transplanted for autoimmune disorders and is strikingly reminiscent of classical AIH, including elevated titres of serum antibodies, hypergammaglobulinaemia, and histological findings of interface hepatitis, bridging fibrosis, and collapse. Like classical AIH, it responds to treatment with prednisolone and azathioprine. De novo AIH post liver transplantation may derive from interference by calcineurin inhibitors with the intrathymic physiological mechanisms of T-cell maturation and selection. Whether this condition is a

    Background Percutaneous biopsy is a widely-accepted technique for acquiring histologic samples of the liver. When there is concern for bleeding, plugged percutaneous biopsy (PPB) may be performed, which involves embolization of the biopsy tract. Purpose To evaluate the efficacy and safety of PPB of the liver in patients suspected to have graft rejection after living-donor liver transplantation (LDLT). Material and Methods During January 2007 and December 2013, 51 patients who underwent PPB of the liver under the suspicion of post-LDLT graft rejection were retrospectively analyzed. A total of 73 biopsies were performed. Biopsy was performed with a 17-gauge core needle and 18-gauge cutting needle. The needle tract was embolized using gelatin sponge (n = 44) or N-butyl cyanoacrylate (NBCA) (n = 29). The specimens were reviewed to determine their adequacy for histologic diagnosis. We reviewed all medical records after PPB. Results Specimens were successfully acquired in all procedures (100%). They were adequate for diagnosis in 70 cases (95.9%) and inadequate in three (1.3%). Average of 9.8 complete portal tracts was counted per specimen. One minor complication (1.4%) occurred where the patient had transient fever after the procedure. Conclusion PPB is easy and safe to perform in LDLT recipients and provides high diagnostic yield.

    Metabolomics as the new omics technique develops after genomics, transcriptomics, and proteomics and has rapid development at present. Liver diseases are worldwide public health problems. In China, chronic hepatitis B and its secondary diseases are the common liver diseases. They can be diagnosed by the combination of history, virology, liver function, and medical imaging. However, some patients seldom have relevant physical examination, so the diagnosis may be delayed. Many other liver diseases, such as drug-induced liver injury (DILI), alcoholic liver disease (ALD) and nonalcoholic fatty liver disease (NAFLD), and autoimmune liver diseases, still do not have definite diagnostic markers; the diagnosis consists of history, medical imaging, and the relevant score. As a result, the clinical work becomes very complex. So it has broad prospects to explore the specific and sensitive biomarkers of liver diseases with metabolomics. In this paper, there are several summaries which are related to the current research progress and application of metabolomics on biomarkers of liver diseases.

    Venous thromboembolic disease is a leading cause of maternal mortality during pregnancy. Early and accurate radiological diagnosis is essential as anticoagulation is not without risk and clinical diagnosis is unreliable. Although the disorder is potentially treatable, unnecessary treatment should be avoided. Most of the diagnostic imaging techniques involve ionizing radiation which exposes both the mother and fetus to finite radiation risks. There is a relative lack of evidence in the literature to guide clinicians and radiologists on the most appropriate method of assessing this group of patients. This article will review the role of imaging of suspected venous thromboembolic disease in pregnant patients, highlight contentious issues such as radiation risk, intravenous contrast use in pregnancy and discuss the published guidelines, as well as suggesting an appropriate imaging algorithm based on the available evidence

    Non-alcoholic fatty liver disease (NAFLD) is one of the most common comorbidities associated with overweight and metabolic syndrome (MetS). Importantly, NAFLD is one of its most dangerous complications because it can lead to severe liver pathologies, including fibrosis, cirrhosis and hepatic cellular carcinoma. Given the increasing worldwide prevalence of obesity, NAFLD has become the most common cause of chronic liver disease and therefore is a major global health problem. Currently, NAFLD is predominantly regarded as a hepatic manifestation of MetS. However, accumulating evidence indicates that the effects of NAFLD extend beyond the liver and are negatively associated with a range of chronic diseases, most notably cardiovascular disease (CVD), diabetes mellitus type 2 (T2DM) and chronic kidney disease (CKD). It is becoming increasingly clear that these diseases are the result of the same underlying pathophysiological processes associated with MetS, such as insulin resistance, chronic systemic inflammation and dyslipidemia. As a result, they have been shown to be independent reciprocal risk factors. In addition, recent data have shown that NAFLD actively contributes to aggravation of the pathophysiology of CVD, T2DM, and CKD, as well as several other pathologies. Thus, NAFLD is a direct cause of many chronic diseases associated with MetS, and better detection and treatment of fatty liver disease is therefore urgently needed. As non-invasive screening methods for liver disease become increasingly available, detection and treatment of NAFLD in patients with MetS should therefore be considered by both (sub-) specialists and primary care physicians.

    The clinical usefulness of single photon emission tomography using rotating chair (ECT), comparing with liver scintigrams was examined with ROC (receiver operating characteristic) curve analysis. The ROC curve of ECT drew higher curved line than that of liver scintigram, i.e. true positive ratio of ECT was slightly inferior to that of liver scintigram, but false positive ratio of ECT was superior to that of liver scintigram. ECT adds useful clinical information to liver scintigram which shows questionable or suspected uptake defects. (author)

    Full Text Available Autoimmune hepatitis is a chronic immune-mediated disease of the liver. In childhood, autoimmune liver disorders include autoimmune hepatitis type I and II, autoimmune sclerosing cholangitis, Coombs-positive giant cell hepatitis, and de novo autoimmune hepatitis after liver transplantation. Autoimmune liver disease has a more aggressive course in children, especially autoimmune hepatitis type II. Standard therapy is a combination of corticosteroids and azathioprine. Around 80 % of children with autoimmune liver disease show a rapid response to combination therapy. The non-responders are treated with more potent drugs, otherwise autoimmune disease progresses to cirrhosis of the liver and the child needs liver transplantation as rescue therapy.

  1. Liver transplantation for Wilson disease.

    Catana, Andreea M; Medici, Valentina

    2012-01-27

    The aim of this paper is to review the current status of liver transplantation (LT) for Wilson disease (WD), focusing on indications and controversies, especially in patients with neuropsychiatric disease, and on identification of acute liver failure (ALF) cases related to WD. LT remains the treatment of choice for patients with ALF, as initial presentation of WD or when anti-copper agents are stopped, and for patients with chronic liver disease progressed to cirrhosis, unresponsive to chelating medications or not timely treated with copper chelating agents. The indication for LT in WD remains highly debated in patients with progressive neurological deterioration and failure to improve with appropriate medical treatment. In case of Wilsonian ALF, early identification is key as mortality is 100% without emergency LT. As many of the copper metabolism parameters are believed to be less reliable in ALF, simple biochemical tests have been proposed for diagnosis of acute WD with good sensitivity and specificity. LT corrects copper metabolism and complications resulting from WD with excellent 1 and 5 year survival. Living related liver transplantation represents an alternative to deceased donor LT with excellent long-term survival, without disease recurrence. Future options may include hepatocyte transplantation and gene therapy. Although both of these have shown promising results in animal models of WD, prospective human studies are much needed to demonstrate their long-term beneficial effects and their potential to replace the need for medical therapy and LT in patients with WD.

    Riestra, S; Fernández, E; Rodrigo, L

    1999-12-01

    Coeliac disease is a gluten-sensitive enteropathy in which, genetic, immunologic and environmental factors are implied. Several extradigestive diseases have been described in association with coeliac disease, which share most of the times an immunologic mechanism. The liver is damaged in coeliac disease, and it has been considered by some authors as an extraintestinal manifestation of the disease. In the present revision we discuss the different hepatic diseases related with the coeliac disease, as well as the best approach to diagnosis and therapy of choice. At diagnosis, it is very frequent to find an asymptomatic hipertransaminasemia, which frequently disappears after gluten suppression; the morphological substratum found in this alteration is a non-specific reactive hepatitis in the majority of cases. Coeliac disease is a demonstrated cause of cryptogenic hipertransaminasemia. In a small percentage of patient with coeliac disease an association has been found with other immunological liver diseases, such as primary biliary cirrhosis, primary sclerosing cholangitis and autoimmune hepatitis. Few studies exist that include a large number of patient, and the results on occasions are discordant. Nevertheless, the strongest association is with autoimmune hepatitis and with primary biliary cirrhosis. Several communications of isolated cases of rare hepatic diseases, which probably, only reflect a fortuitous association, have been cited in the literature.

    Liver transplantation remains an effective treatment for those with end-stage disease and with intractable liver-related symptoms.The shortage of organs for transplantation has resulted in the need for rationing.A variety of approaches to selection and allocation have been developed and vary from country to country.The shortage of donors has meant that new approaches have to be adopted to make maximal use of the available organs;these include splitting grafts,use of extended criteria livers,livers from nonheart-beating donors and from living donors.Post transplantation, most patients will need life-long immunosuppression,although a small proportion can have immunosuppression successfully withdrawn.Newer immunosuppressive drugs and different strategies may allow a more targeted approach with a reduction in sideeffects and so improve the patient and graft survival.For autoimmune diseases, transplantation is associated with significant improvement in the quality and length of life.Disease may recur after transplantation and may affect patient and graft survival.

    2016-01-01

    Background: Bisphenol A (BPA) is a widely used industrial chemical and suspected endocrine disruptor to which humans are ubiquitously exposed. The liver metabolizes and facilitates BPA excretion through glucuronidation and sulfonation. The sulfotransferase enzymes contributing to BPA sulfonation (detected in human and rodents) is poorly understood. Objectives: To determine the impact of metabolic and liver disease on BPA sulfonation in human and mouse livers. Methods: The capacity for BPA sulfonation was determined in human liver samples that were categorized into different stages of metabolic and liver disease (including obesity, diabetes, steatosis, and cirrhosis) and in livers from ob/ob mice. Results: In human liver tissues, BPA sulfonation was substantially lower in livers from subjects with steatosis (23%), diabetes cirrhosis (16%), and cirrhosis (18%), relative to healthy individuals with non-fatty livers (100%). In livers of obese mice (ob/ob), BPA sulfonation was lower (23%) than in livers from lean wild-type controls (100%). In addition to BPA sulfonation activity, Sult1a1 protein expression decreased by 97% in obese mouse livers. Conclusion: Taken together these findings establish a profoundly reduced capacity of BPA elimination via sulfonation in obese or diabetic individuals and in those with fatty or cirrhotic livers versus individuals with healthy livers. - Highlights: • Present study demonstrates that hepatic SULT 1A1/1A3 are primarily sulfonate BPA in mouse and human. • Hepatic BPA sulfonation is profoundly reduced steatosis, diabetes and cirrhosis. • With BPA-S detectable in urine under low or common exposures, these findings are novel and important.

    Meningococcal disease can lead to death or disability within hours after onset. Pre-admission antibiotics aim to reduce the risk of serious disease and death by preventing delays in starting therapy before confirmation of the diagnosis. To study the effectiveness and safety of pre-admission antibiotics versus no pre-admission antibiotics or placebo, and different pre-admission antibiotic regimens in decreasing mortality, clinical failure, and morbidity in people suspected of meningococcal disease. We searched CENTRAL (6 January 2017), MEDLINE (1966 to 6 January 2017), Embase (1980 to 6 January 2017), Web of Science (1985 to 6 January 2017), LILACS (1982 to 6 January 2017), and prospective trial registries to January 2017. We previously searched CAB Abstracts from 1985 to June 2015, but did not update this search in January 2017. Randomised controlled trials (RCTs) or quasi-RCTs comparing antibiotics versus placebo or no intervention, in people with suspected meningococcal infection, or different antibiotics administered before admission to hospital or confirmation of the diagnosis. Two review authors independently assessed trial quality and extracted data from the search results. We calculated the risk ratio (RR) and 95% confidence interval (CI) for dichotomous data. We included only one trial and so did not perform data synthesis. We assessed the overall quality of the evidence using the GRADE approach. We found no RCTs comparing pre-admission antibiotics versus no pre-admission antibiotics or placebo. We included one open-label, non-inferiority RCT with 510 participants, conducted during an epidemic in Niger, evaluating a single dose of intramuscular ceftriaxone versus a single dose of intramuscular long-acting (oily) chloramphenicol. Ceftriaxone was not inferior to chloramphenicol in reducing mortality (RR 1.21, 95% CI 0.57 to 2.56; N = 503; 308 confirmed meningococcal meningitis; 26 deaths; moderate-quality evidence), clinical failures (RR 0.83, 95% CI 0.32 to

  8. COAGULATION ACTIVITY IN LIVER DISEASE

    Full Text Available Patients with advanced hepatic failure may present with the entire spectrum of coagulation factor deficiencies. This study was designed to determine laboratory abnormalities in coagulation in chronic liver disease and the association of these abnormalities with the extent of chronic hepatitis and cirrhosis. Coagulation markers were assayed in 60 participants: 20 patients with chronic hepatitis, 20 patients with cirrhosis, and 20 healthy individuals (control. Plasma levels of anti-thrombin III were determined by a chromogenic substrate method, and plasma concentrations of fibrinogen were analyzed by the Rutberg method. Commercially available assays were used for laboratory coagulation tests. The levels of coagualation activity markers in patients with chronic liver disease were significantly different in comparison to those in healthy participants. These results indicate the utility of measuring markers for coagulation activity in determining which cirrhosis patients are more susceptible to disseminated intravascular coagulation.

  9. Alcoholic Liver Disease and Malnutrition

    2013-01-01

    Malnutrition, both protein energy malnutrition (PEM) and deficiencies in individual nutrients, is a frequent complication of alcoholic liver disease (ALD). Severity of malnutrition correlates with severity of ALD. Malnutrition also occurs in patients with cirrhosis due to etiologies other than alcohol. The mechanisms for malnutrition are multifactorial, and malnutrition frequently worsens in the hospital due to fasting for procedures and metabolic complications of liver disease, such as hepatic encephalopathy. Aggressive nutritional support is indicated in inpatients with ALD, and patients often need to be fed through an enteral feeding tube to achieve protein and calorie goals. Enteral nutritional support clearly improves nutrition status and may improve clinical outcome. Moreover, late-night snacks in outpatient cirrhotics improve nutritional status and lean body mass. Thus, with no FDA-approved therapy for ALD, careful nutritional intervention should be considered as frontline therapy. PMID:21284673

    Renal dysfunction is common in liver diseases, either as part of multiorgan involvement in acute illness or secondary to advanced liver disease. The presence of renal impairment in both groups is a poor prognostic indicator. Renal failure is often multifactorial and can present as pre-renal or intrinsic renal dysfunction. Obstructive or post renal dysfunction only rarely complicates liver disease. Hepatorenal syndrome (HRS) is a unique form of renal failure associated with advanced liver dise...

    Fatty liver disease is defined as an abnormal accumulation of lipids into the cytoplasm of hepatocytes. Different kinds of fatty liver diseases are becoming the most important etiologies of end-stage liver disease in the western world. Because fatty liver is a theoretically reversible process, timely and accurate diagnosis is a prerequisite for potential therapeutic options. This work describes major diagnostic methods and discusses particular advantages and disadvantages of various techniques.

    Full Text Available Nonalcoholic fatty liver disease (NAFLD is increasing in pediatric age group parallel to the growing prevalence of obesity and overweight all around the world. So changing in life style and   interventions on obesogenic environment is cornerstone of NAFLD therapy in obese children. Some experts recommend that children and adolescents be encouraged to follow a low-fat, low-glycemic-index diet that includes eating a minimum of 5 servings of vegetables and fruits daily, engaging in physical activity for at least 1 hour daily, and minimizing television/computer time to 2 hours daily.  In spite of effectiveness of weight loss and exercise in improvement NAFLD, this goal is very difficult to be achieved and pharmacological approaches have become necessary. Pharmacologic therapies against one or more specific factors and/or molecules involved in the development of NAFLD (i.e., insulin resistance, free fatty acid lipid toxicity, and oxidative stress also might slow the progression of NAFLD to NASH or cirrhosis.  On this basis, insulin sensitizers, antioxidants, cytoprotective agents, and dietary supplementations have been evaluated in pediatric clinical trials but there is no approved pharmacologic therapy for NAFLD or NASH. Not all obese children affected by NAFLD. Diet modification and regular exercise beside to serial medical follow up highly suggested for this group of children. Normal weight and thin children with NAFLD or NASH should be investigated appropriately in a logical manner based on causes of primary liver steatosis in children and treatment of underlying disease can cause improvement fatty liver in these patients.   Keywords: Non-alcoholic fatty liver disease; Non-alcoholic steatohepatitis; Children; Steatosis; Treatment

    Autoimmune liver diseases (ALDs) are known to be associated with systemic autoimmune rheumatic diseases (SARDs) and their autoantibodies. We aimed to study the prevalence of SARDs and related autoantibodies, as well as their prognostic implications in a group of patients with ALDs. This was a cross-sectional study. Sixty patients with ALDs (38.3% with autoimmune hepatitis; 11.7% with primary biliary cirrhosis; 25% with primary sclerosing cholangitis and 25% with overlap syndrome) were studied for the presence of SARDs and their autoantibodies. There was autoimmune rheumatic disease in 20% of the studied sample. Systemic lupus erythematosus (SLE) and rheumatoid arthritis (RA) were the commonest (11.6% and 5%, respectively). Antinuclear antibodies (ANAs) were present in 35% of the patients, followed by anti-Ro (20.0%); anti-nucleosome (18.3%); rheumatoid factor (10%) anti-CCP (8.3%); anti-RNP (8.3%); anti-ds-DNA (6.6%); anti-La (3.3%); anti-Sm (3.3%), anti-ribosomal P (3.3%). Anti-Ro (p = 0.0004), anti-La (p = 0.03), anti-RNP (p = 0.04) and anti-Sm (p = 0.03) were commonly found in patients with SARD, but not anti-DNA, anti-nucleosome and anti-ribosomal P. No differences were found in liver function tests regarding to the presence of autoantibodies. There was a high prevalence of SARD and their autoantibodies in ALD patients. Anti-Ro, anti-La, anti-RNP and anti-Sm positivity points to an association with systemic autoimmune rheumatic diseases. The presence of autoantibodies was not related to liver function tests.

    The pathogenetic mechanisms of anemia in patients with chronic liver disease were observed. Seventeen patients with moderate to advanced hepatic diseases were studied by various methods. Only patients without previous blood loss were included : 14 had cirrhosis, 2 had active chronic hepatitis, and one had inferior vena cava obstruction with associated liver cirrhosis. The followings were the results: 1. The anemia based on red blood cell count, Hb., and Ht. was found in 76.5-78.6% of the patients. 2. Red cell indices indicated that normo-macrocytic and normochromic anemia was present is the majority of the patients. 3. No evidence of megaloblastic anemia was found on the basis of the morphological examinations. 4. Serum iron, TIBC, % saturation and iron content in the bone marrow indicated that iron deficiency anemia was present in about half of the patients. 5. In the view of the erythrocyte dynamics, primary increase in the red cell destruction was ascribed to the cause of the anemia. 6. Decrease in the red cell survival time was not correlated with MCV, % saturation and S.L. ratio. Also, hemoglobin level was not correlated with MCV, % saturation and T{sub 50} Cr. Therefore, multiple causes may be involved in the pathogenesis of the anemia. 7. Anemia as determined by the red cell volume was found in only 60% of the patients. It may be possible that hemodilutional anemia is present.

    To evaluate the prevalence and clinical profile of autoimmune hepatitis (AIH) in patients with chronic liver disease. Four hundred and thirty five consecutive patient with chronic liver disease seen in our department from January 1997 to December 1998 were studied with detailed history and clinical examination. All the patients underwent liver function tests, ultrasonography, isotope liver scanning, viral markers, autoimmune markers ANA, ASMA, LKM1 and AMA (by immunofluorescence technique) and liver histology whenever permissible. Appropriate work up for Wilson's disease was done whenever suspected clinically. Diagnosis of autoimmune hepatitis was made by the composite scoring system by international autoimmune hepatitis group. Twenty out of the 435 patients met the criteria of definite autoimmune hepatitis and seven patient had probable autoimmune hepatitis. Forty out of 408 patients showed markers of autoimmunity positive but did not qualify diagnosis of AIH on composite scores. Demographic profile of 27 patients with autoimmune hepatitis was as follows; male:female ratio 1:8, mean age 39.8 +/- 13 years (Range 4-65 years); mode of presentation as cirrhosis 11/27 (40.7%), chronic hepatitis 12/27 (44.4%) and acute hepatitis 4/27 (14.8%). Elevated serum bilirubin levels were seen in 12 (44.4%) patients while mean serum aminotransferases levels were 249 +/- 343 and 262 +/- 418 respectively. Other disease associations seen were as follows: diabetes in 4 (14.8%), rheumatoid arthritis in 3 (11%), hypothyroidism in 2 (7.4%) and ulcerative colitis in 1 (3.7%). The pattern of autoimmune markers was ANA +ve 23/27 (85%) (+ve titres of ANA > 1:80 in adults and 1:20 in children), ASMA +ve in 16/27 (59.2%) (+ve titres of ASMA > 1:40) and LKM1 in 3 patients. AMA in tires less than 1:80 was found in 3 patients. Liver histology changes seen were lymphoplasmacytic infiltrates (100%), bridging necrosis (93%), liver cell rossetting (80%) and fibrosis with or without cirrhosis (50

    Early experience with body CT suggested its usefulness in many diagnostic problems; jaundice, renal and pancreatic masses, and in the evaluation of relatively inaccessible parts of the body, such as the retroperitineum, mediastinum, and pelvis. Investigation of hepatic disease by CT was not unexpectedly compared to radionuclide liver scanning, the major preexisting modality for imaging the liver. In the evaluation of the jaundiced patient, CT rapidly assumed a major role, providing more specific information about the liver than the RN liver scan, as well as demonstrating adjacent organs. CT differentiate obstructive from non-obstructive jaundice. With respect to mass lesions of the liver, the RN liver scan is more sensitive than CT but less specific. The abnormalities on an isotope image of the liver consist of normal variants in configuration, extrinsic compression by adjacent structures, cysts, hemangiomata, abscesses, and neoplasms. These suspected lesions may then be better delineated by the CT image, and a more precise diagnosis made. The physiologic information provided by the RN liver scan is an added facet which is helpful in the patient with diffuse hepatic disease. The CT image will be normal in many of these patients, however, hemochromatosis and fatty infiltration lend themselves especially to density evaluation by CT. The evaluation of lymphoma is more thorough with CT. Structures other than the liver, such as lymph nodes, are visualized. Gallium, however, provides additional isotopic information in patients with lymphoma, and in addition, is known to be useful in the investigation of a febrile patient with an abscess. Newer isotopic agents expand hepatic imaging in other directions, visualizing the biliary tree and evaluating the jaundiced patient

    Full Text Available Traditional Chinese medicine (TCM treatment of liver diseases is derived from the regulation of liver function including storing blood and governing the free flow of qi, in which functional systems such as modern digestion, endocrine, and the gut-liver axis are involved, and is established on modern hepatic physiology, pathology, and etiology. To objectively reveal the characteristics and advantages of modern TCM treatment of liver diseases, we analyzed the clinical and research situation of TCM therapy for liver diseases in the last decade and collected major achievements that have been applied in clinical treatment of diseases, published in core journals, and confirmed by major scientific research programs. The results showed TCM combined with antiviral therapy can improve the clinical outcomes of chronic hepatitis B. TCM can help HBV carriers prevent disease progression. Integrated traditional Chinese and Western medicine therapy for acute-on-chronic liver failure can block the deterioration induced by endotoxin. TCM has been widely applied in protecting the liver through nonspecific anti-inflammation, alleviating hepatic fibrosis, and preventing non-alcoholic fatty liver. TCM plays an important role in treating some currently untreatable liver diseases. Therefore, it is our common responsibility to inherit and develop effective principle-method-recipe-medicines and create a better medical care system.

    Weight loss and muscle wasting are commonly found in patients with end-stage liver disease. Since there is an association between malnutrition and poor clinical outcome, such patients (or those at risk of becoming malnourished) are often given parenteral nutrition, enteral nutrition, or oral nutritional supplements. These interventions have costs and adverse effects, so it is important to prove that their use results in improved morbidity or mortality, or both. To assess the beneficial and harmful effects of parenteral nutrition, enteral nutrition, and oral nutritional supplements on the mortality and morbidity of patients with underlying liver disease. The following computerised databases were searched: the Cochrane Hepato-Biliary Group Controlled Trials Register, the Cochrane Central Register of Controlled Trials (CENTRAL) (The Cochrane Library), MEDLINE, EMBASE, and Science Citation Index Expanded (January 2012). In addition, reference lists of identified trials and review articles and Clinicaltrials.gov were searched. Trials identified in a previous systematic handsearch of Index Medicus were also considered. Handsearches of a number of medical journals, including abstracts from annual meetings, were done. Experts in the field and manufacturers of nutrient formulations were contacted for potential references. Randomised clinical trials (parallel or cross-over design) comparing groups of patients with any underlying liver disease who received, or did not receive, enteral or parenteral nutrition or oral nutritional supplements were identified without restriction on date, language, or publication status. Six categories of trials were separately considered: medical or surgical patients receiving parenteral nutrition, enteral nutrition, or supplements. The following data were sought in each report: date of publication; geographical location; inclusion and exclusion criteria; the type of nutritional support and constitution of the nutrient formulation; duration of

    Hepatocellular carcinoma is one of the main important causes of cancer-related death and its mortality is increasingly worldwide. In Europe, alcohol abuse accounts for approximately half of all liver cancer cases and it will become the leading cause of hepatocellular carcinoma in the next future with the sharp decline of chronic viral hepatitis. The pathophysiology of alcohol-induced carcinogenesis involves acetaldehyde catabolism, oxidative stress and chronic liver inflammation. Genetic background plays also a significant role and specific patterns of gene mutations in alcohol-related hepatocellular carcinoma have been characterized. Survival is higher in patients who undergo specific surveillance programmes than in patients who do not. However, patients with alcohol cirrhosis present a significantly greater risk of liver decompensation than those with cirrhosis due to other aetiologies. Furthermore, the adherence to screening program can be suboptimal. Liver transplant for patients with Milan-in hepatocellular carcinoma represents the best possible treatment in case of tumour recurrence/progression despite loco-regional or surgical treatments. Long-term result after liver transplantation for alcohol related liver disease is good. However, cardiovascular disease and de novo malignancies can significantly hamper patients' survival and should be carefully considered by transplant team. In this review, we have focused on the evolution of alcohol-related hepatocellular carcinoma epidemiology and risk factors as well as on liver transplantation in alcoholic patients with and without hepatocellular carcinoma.

    Carcinoembryonic antigen was initially known as tumor specific antigen and had a potential diagnostic value in the detection of digestive tract malignancies. However, subsequent studies showed CEA and CEA-like antigen present in benign disease, particularly in liver. We had collected sera from 58 patients who had liver scan and later were diagnosed clinically and histologically as liver disease. We estimated CEA values and correlations were made with liver function tests in liver cirrhosis cases. The results: 1) The raised plasma carcinoembryonic antigen level were found in 13 (68.4%) of 19 patients cirrhosis, 5 (27.8%) of 18 patients in hepatoma, 5 (71%) of 7 patients in chronic active hepatitis, all 3 patients in liver abscesses, 2 (66.7%) of 3 patients in liver abscesses, 2 (66.7%) of 3 patients in obstructive biliary disease and none in each one patient of traumatic liver hematoma, subphrenic abscess and clonorchiasis. 2) There is no linear correlation between carcinoembryonic antigen level and liver function tests including serum bilirubin, alkaline phosphatase, SGOT and prothrombin time in liver patients.

    Full Text Available Background: In recent times, there are reports of adrenal dysfunction in whole spectrum of liver disease. Adrenal insufficiency (AI has been shown to correlate with progression of liver disease. Hence this study was conducted to assess adrenal function in subjects with acute liver disease (ALD, chronic liver disease (CLD and post liver transplantation (LT. Material and Methods: This study included 25 healthy controls, 25 patients of ALD, 20 subjects of CLD with Child-Pugh stage A (CLD-1 and 30 with Child-Pugh stage B or C (CLD-2, and 10 subjects with LT. All subjects were assessed clinically, biochemically and for adrenal functions. Results: AI was present in 9 (34.6% patients with ALD, 20 (40% patients with CLD and 4 (40% in subjects with LT. AI was more common in CLD-2 (18 patients - 60% than CLD-1 (2 patients - 10%. All patients with chronic liver disease had significantly lower basal cortisol (8.8±4.8, P=0.01, stimulated cortisol (18.2±6.3, P <0.00001 and incremental cortisol (9.4±4.6, P <0.00001 as compared to controls. There was increase in percentage of subjects with adrenal dysfunction with progression of liver disease as assessed by Child-Pugh staging. AI was predicted by lower levels of serum protein, serum albumin, total cholesterol and HDL cholesterol and higher levels of serum bilirubin and INR. Adrenal functions showed recovery following liver transplantation. Conclusions: AI forms important part of spectrum of acute and chronic liver disease. Deterioration of synthetic functions of liver disease predicts presence of AI, and these patients should be evaluated for adrenal dysfunction periodically.

    The clinical, electrophysiological and neuroradiological features of thirteen patients suffering from progressive neuronal degeneration of childhood with liver failure are presented. The disease commonly presents very early in life with progressive mental retardation, followed by intractable epilepsy, and should be suspected clinically especially if there is a family history of similar disorder in a sibling. On computed tomography there are low density regions, particularly in the occipital and posterior temporal lobes, involving both cortex and white matter, combined with or followed by progressive atrophy. Typical EEG findings may be confirmatory. (orig.)

    Background. In the healthy liver there is a splanchnic net-uptake of lactate caused by gluconeogenesis. It has previously been shown that patients with acute liver failure in contrast have a splanchnic release of lactate caused by a combination of accelerated glycolysis in the splanchnic region...... and a reduction in hepatic gluconeogenesis. Aims. The aims of the present study were to investigate lactate metabolism and kinetics in patients with chronic liver disease compared with a control group with normal liver function. Methods. A total of 142 patients with chronic liver disease and 14 healthy controls...... underwent a liver vein catheterization. Blood samples from the femoral artery and the hepatic and renal veins were simultaneously collected before and after stimulation with galactose. Results. The fasting lactate levels, both in the hepatic vein and in the femoral artery, were higher in the patients than...

    Cirrhotic patients are known to have abnormally high signal principally in the globus pallidus on non-contrast T1-weighted MRI. The purpose of this study was to relate MR changes to clinical and pathological features of chronic liver disease. We confirmed abnormally high signal in the globus pallidus on T1-weighted images in 25 of 28 patients with chronic liver disease, showing that it also occurs in patients who have not yet progressed to cirrhosis. Changes were seen in patients both with and without clinical portosystemic shunting. This abnormality is not responsible for hepatic encephalopathy. Cholestatic disease was more likely to produce marked changes than non-cholestatic disease. No statistically significant correlation was demonstrated between the severity of liver disease and the degree of MR abnormality. However, marked improvement in MR appearances was seen after successful liver transplantation. (orig.). With 3 figs., 4 tabs.

    Cirrhotic patients are known to have abnormally high signal principally in the globus pallidus on non-contrast T1-weighted MRI. The purpose of this study was to relate MR changes to clinical and pathological features of chronic liver disease. We confirmed abnormally high signal in the globus pallidus on T1-weighted images in 25 of 28 patients with chronic liver disease, showing that it also occurs in patients who have not yet progressed to cirrhosis. Changes were seen in patients both with and without clinical portosystemic shunting. This abnormality is not responsible for hepatic encephalopathy. Cholestatic disease was more likely to produce marked changes than non-cholestatic disease. No statistically significant correlation was demonstrated between the severity of liver disease and the degree of MR abnormality. However, marked improvement in MR appearances was seen after successful liver transplantation. (orig.). With 3 figs., 4 tabs

    Patients with end-stage isolated polycystic liver disease (PCLD) suffer from incapacitating symptoms because of very large liver volumes. Liver transplantation (LT) is the only curative option. This study assesses the feasibility of LT in PCLD. We used the European Liver Transplant Registry (ELTR......) database to extract demographics and outcomes of 58 PCLD patients. We used Kaplan-Meier survival analysis for survival rates. Severe abdominal pain (75%) was the most prominent symptom, while portal hypertension (35%) was the most common complication in PCLD.

    Creutzfeldt-Jakob disease (CJD) is a fatal neurodegenerative disorder in which accumulation of the pathogenic prion protein induces neuronal damage and results in distinct pathologic features. This abnormal prion is an infectious protein and resistant to methods of sterilization currently being used. Therefore, management of definite, or suspected CJD patients requires additional precautions. We report our experience of a patient who had undergone brain biopsy for suspected of CJD. The patient was confirmed to have sporadic CJD.

It is regulated on several levels, with different cellular populations contributing to this process, eg, hepatocytes, liver precursor cells, intrahepatic stem cells. In response to injury, mature hepatocytes have the capability to proliferate and give rise to new hepatocytes and cholangiocytes. Meanwhile, liver precursor cells (oval cells have become the most recognized bipotential precursor cells in the damaged liver. They rapidly proliferate, change their cellular composition, and differentiate into hepatocytes and cholangiocytes to compensate for the cellular loss and maintain liver homeostasis. There is a growing body of evidence that oval cells originate from the intrahepatic stem cell(s, which in turn give(s rise to epithelial, including oval cells, and/or other hepatic cells of nonepithelial origin. Since there is a close relationship between the liver and hematopoiesis, bone marrow derived cells can also contribute to liver regeneration by the fusion of myeloid cells with damaged hepatocytes, or differentiation of mesenchymal stem cells into hepatocyte-like cells. The current review discusses the contribution of different cells to liver regeneration and their characteristics.Keywords: hepatic progenitor, liver disease, liver precursor cells, oval cells, hepatocytes, intrahepatic stem cells, cholangiocytes

    2008-01-01

    A structured literature review was performed to detail the frequency and etiology of chronic liver disease (CLD) in Aboriginal North Americans. CLD affects Aboriginal North Americans disproportionately and is now one of the most common causes of death.Alcoholic liver disease is the leading etiology of CLD,but viral hepatitis, particularly hepatitis C, is an important and growing cause of CLD. High rates of autoimmune hepatitis and primary biliary cirrhosis (PBC) are reported in regions of coastal British Columbia and southeastern Alaska. Non-alcoholic liver disease is a common, but understudied, cause of CLD.Future research should monitor the incidence and etiology of CLD and should be geographically inclusive.In addition, more research is needed on the treatment of hepatitis C virus (HCV) infection and non-alcoholicfatty liver disease (NAFLD) in this population.

    Polycystic liver disease (PCLD) is a condition in which multiple cysts form in the hepatic parenchyma. The polycystic liver disease is also an autosomal dominant disorder (ADPLD) caused by a mutation in a gene that encodes a protein hepatocystin. PCLD has a prevalence count of 1:200,000 people in the people of America. PCLD occurs ± 24% of patients in the third decade of age to 80% by the sixth decade. Women tend to get larger cysts and more and correlated with the number of pregnancies. The following case report of a woman, 51-years-old who was treated at Haji Adam Malik hospital Medan with a diagnosis of polycystic liver disease with right pleural effusion. Some literature has reported complications of the polycystic liver disease but rarely reported with pleural effusion presentation. The patient had already undergone a puncture of pleural fluid and after three weeks of treatment condition of the patient improved and permitted to be outgoing patient.

    Patients with gastric cancer and liver metastases are believed not to benefit from gastric resection. In 43 patients with strong suspicion of-or proven-gastric cancer, fit for elective, radical surgery, preoperative liver scintigraphy was performed, in an attempt to select patients with liver metastases before laparotomy. Liver scintigraphy identified 6 out of 7 patients with metastases. Percutaneous scan-guided fine-needle aspiration biopsy verified 4 true positive scintigrams. True positive scintigrams in 2 patients heralded a change in the planned treatment. We consider that a preoperative liver scintigraphy in a population thus selected is beneficial in the planning of treatment: only patients with a negative scan-guided fine-needle aspiration biopsy should be operated upon.

    Patient: Female, 24 Final Diagnosis: Pinworms infection Symptoms: Abdominal pain • bloating Medication: — Clinical Procedure: Colonoscopy and biopsy Specialty: Gastroenterology and Hepatology Objective: Rare disease Background: Inflammatory bowel disease (IBD) is well recognized in developed countries and is generally among the differential diagnoses of young patients presenting with refractory diarrhea once other more common etiologies have been excluded. Pinworm infections, on the other hand, are not as common among adults in the United States. Case Report: Based on computed tomography features, a 24-year-old female patient with a history of multiple autoimmune disorders presented with abdominal pain and was diagnosed recently with Crohn’s disease. Colonoscopy was significant for pinworms seen throughout the colon. Colonic biopsy was negative for inflammatory bowel disease (IBD)-related changes. Conclusions: The diagnosis of IBD is a serious label that requires biopsy confirmation before committing to possibly lifelong treatment and possible adverse effects. Even in the most typical patient and when the presentation and imaging are classical, uncommon conditions (like Enterobius infection in this case) may preclude appropriate diagnosis and management.

    To show that Wilson's disease is one likely cause of multiple low-intensity nodules of the liver we obtained MR images in 16 patients with clinically and histopathologically confirmed Wilson's disease. Corresponding to morphological changes MRI enabled the subdivision of the patients into two groups. Using a T 2 -weighted spin-echo sequence (TR/TE=2000/45-90) liver parenchyma showed multiple tiny low-intensity-nodules surrounded by high-intensity septa in 10 out of 16 patients. 5 patients had also low-intensity nodules in T 1 -weighted images (TR/TE=600/20). In patients of this group histopathology revealed liver cirrhosis (n=7) and fibrosis (n=2). Common feature of this patient group was marked inflammatory cell infiltration into fibrous septa, increase of copper concentration in liver parenchyma and distinct pathological changes of laboratory data. In the remaining 6 patients no pathological change of liver morphology was demonstrated by MRI corresponding to slight histopathological changes of parenchyma and normal laboratory data. As low-intensity nodules surrounded by high intensity septa can be demonstrated in patients with marked inflammatory infiltration of liver parenchyma MRI may help to define Wilson patients with poorer prognosis. In patients with low-intensity nodules of the liver and unknown cause of liver cirrhosis laboratory data and histopathology should be checked when searching for disorders of copper metabolism.

    Full Text Available Nonalcoholic fatty liver disease (NAFLD is one of the most important chronic liver diseases worldwide and has garnered increasing attention in recent decades. NAFLD is characterized by a wide range of liver changes, from simple steatosis to nonalcoholic steatohepatitis, cirrhosis, and hepatocellular carcinoma. The blurred pathogenesis of NAFLD is very complicated and involves lipid accumulation, insulin resistance, inflammation, and fibrogenesis. NAFLD is closely associated with complications such as obesity, diabetes, steatohepatitis, and liver fibrosis. During the progression of NAFLD, reactive oxygen species (ROS are activated and induce oxidative stress. Recent attempts at establishing effective NAFLD therapy have identified potential micronutrient antioxidants that may reduce the accumulation of ROS and finally ameliorate the disease. In this review, we present the molecular mechanisms involved in the pathogenesis of NAFLD and introduce some dietary antioxidants that may be used to prevent or cure NAFLD, such as vitamin D, E, and astaxanthin.

    Background: Spontaneous bacterial peritonitis (SBP) is defined as infected ascites in the absence of any recognizable secondary cause of infection. Objectives: To find out the percentage of SBP in patients of chronic liver disease with ascites, its clinical and laboratory characteristics. Place and Duration of Study: Medical ward II, Jinnah Hospital Lahore and duration of study was six months. Study Design: Descriptive/ Observational study. Subjects and Method: One hundred patients of chronic liver disease with ascities were included in this study. Diagnostic paracentesis was performed immediately upon admission and the bacterial cultures and biochemical analysis was done on sample. Results: Ascitic fluid examination was the main basis for establishing the diagnosis of SBP. It was found that SBP was present in 22 patients, out of which 11 were culture positive and 11 were culture negative, 35 patients were HBsAg positive and 65 patients were anti HCV positive. SBP was found in 22 patients out of whom 10 were males and 12 females. Ascites was present in all the patients (100%). Shifting dullness was present in 76 (76%) cases, fluid thrill in 24 cases (24%) and tenderness in 47 patients (47%). Conclusion: Frequency of SBP is quite high in patients with chronic liver disease with ascites. SBP should be suspected in all such cases presenting with typical or atypical features. (author)

  10. Autoimmune liver disease in children.

    Mieli-Vergani, G; Vergani, D

    2003-03-01

    Autoimmune liver disorders are characterised by an inflammatory liver histology, circulating non-organ specific autoantibodies and increased levels of immunoglobulin G (IgG) in the absence of a known aetiology. They respond to immunosuppressive treatment, which should be instituted as soon as diagnosis is made. Liver disorders with a likely autoimmune pathogenesis include autoimmune hepatitis (AIH) and autoimmune sclerosing cholangitis (ASC). Two types of AIH are recognised according to seropositivity for smooth muscle and/or antinuclear antibody (SMA/ANA, type 1) or liver kidney microsomal antibody (LKM1, type 2). There is a female predominance in both. LKM1-positive patients tend to present more acutely, at a younger age, and commonly have immunoglobulin A (IgA) deficiency, while duration of symptoms before diagnosis, clinical signs, family history of autoimmunity, presence of associated autoimmune disorders, response to treatment and long-term prognosis are similar in both groups. The most common type of paediatric sclerosing cholangitis is ASC. The clinical, biochemical, immunological and histological presentation of ASC is often indistinguishable from that of AIH. In both, there are high IgG, non-organ specific autoantibodies and interface hepatitis. Diagnosis is made by cholangiography. Children with ASC respond to immunosuppression satisfactorily and similarly to AIH in respect to remission and relapse rates, times to normalisation of biochemical parameters and decreased inflammatory activity on follow-up liver biopsies. However, the cholangiopathy can progress and there may be an evolution from AIH to ASC over the years, despite treatment. Whether the juvenile autoimmune form of sclerosing cholangitis and AIH are 2 distinct entities, or different aspects of the same condition, remains to be elucidated.

    In the setting of clinically suspected Legg-Calve-Perthes (LCP) disease and negative/equivocal radiographs, contrast-enhanced MRI can be performed to confirm the diagnosis. To determine the frequency of unexpected causes of hip pain as identified by MRI in children with clinically suspected LCP disease and negative/equivocal radiographs. All pediatric contrast-enhanced MRI examinations of the pelvis and hips performed between January 2000 and February 2009 to evaluate for possible LCP disease in the setting of negative/equivocal radiographs were identified. MRI examinations performed to evaluate for secondary avascular necrosis were excluded. Imaging reports were retrospectively reviewed for unexpected clinically important causes of hip pain. Thirty-six pediatric patients underwent contrast-enhanced MRI examinations for clinically suspected LCP disease in the setting of negative/equivocal radiographs. Twenty-two (61%) imaging studies were normal, while four (11%) imaging studies demonstrated findings consistent with LCP disease. Ten (28%) imaging studies revealed unexpected clinically important causes of hip pain, including nonspecific unilateral joint effusion and synovitis (n = 7, juvenile chronic arthritis was eventually diagnosed in 3 patients), sacral fracture (n = 1), apophyseal injury (n = 1), and femoral head subluxation (n = 1). MRI frequently reveals unexpected clinically important causes of hip pain in children with suspected LCP disease and negative/equivocal radiographs. (orig.)

  12. Acetaldehyde Adducts in Alcoholic Liver Disease

    Full Text Available Chronic alcohol abuse causes liver disease that progresses from simple steatosis through stages of steatohepatitis, fibrosis, cirrhosis, and eventually hepatic failure. In addition, chronic alcoholic liver disease (ALD, with or without cirrhosis, increases risk for hepatocellular carcinoma (HCC. Acetaldehyde, a major toxic metabolite, is one of the principal culprits mediating fibrogenic and mutagenic effects of alcohol in the liver. Mechanistically, acetaldehyde promotes adduct formation, leading to functional impairments of key proteins, including enzymes, as well as DNA damage, which promotes mutagenesis. Why certain individuals who heavily abuse alcohol, develop HCC (7.2–15% versus cirrhosis (15–20% is not known, but genetics and co-existing viral infection are considered pathogenic factors. Moreover, adverse effects of acetaldehyde on the cardiovascular and hematologic systems leading to ischemia, heart failure, and coagulation disorders, can exacerbate hepatic injury and increase risk for liver failure. Herein, we review the role of acetaldehyde adducts in the pathogenesis of chronic ALD and HCC.

    Radiation-induced liver disease (RILD) or radiation hepatitis is a sub-acute form of liver injury due to radiation. It is one of the most dreaded complications of radiation which prevents radiation dose escalation and re irradiation for hepatobiliary or upper gastrointestinal malignancies. This complication should be kept in mind whenever a patient is planned for irradiation of these malignancies. Although, incidence of RILD is decreasing due to better knowledge of liver tolerance, improved investigation modalities and modern radiation delivery techniques, treatment options are still limited. In this review article, we have focussed on pathophysiology, risk factors, prevention and management of RILD

    Full Text Available Background and aims: Nonalcoholic fatty liver disease (NAFDL is a multifactorial condition with a wide spectrum of histological severities, from asymptomatic hepatic steatosis to nonalcoholic steatohepatitis (NASH with or without fibrosis. NAFLD is highly common and potentially serious in children and adolescents and affects approximately one third of the general population. It is closely associated with obesity, insulin resistance and dyslipidemia. NASH is a histological diagnosis and has a great significance because it can progress to cirrhosis, liver failure, and hepatocellular carcinoma (HCC, and is associated with both increased cardiovascular and liver related mortality. The purpose of this review is to summarize the evidence for current potential therapies of NAFLD.

    There are several initiatives to develop systems for the notification of suspected occupational disease (OD) in different autonomous communities. The objective was to describe the status of development and characteristics of these systems implemented by the health authorities. A cross-sectional descriptive study was carried out on the existence of systems for the information and surveillance of suspected OD, their legal framework, responsible institution and availability of information. A specific meeting was held and a survey was designed and sent to all autonomous communities and autonomous cities (AACC). Information was collected on the existence of a regulatory standard, assigned human resources, notifiers, coverage and number of suspected OD received, processed and recognized. 18 of 19 AACC responded. 10 have developed a suspected OD notification system, 3 of them supported by specific autonomic law. The notifiers were physicians of the public health services, physicians of the occupational health services and, in 2 cases, medical inspectors. 7 AACC had specific software to support the system. The OD recognition rate of suspected cases was 53% in the Basque Country; 41% in Castilla-La Mancha; 36% in Murcia; 32.6% in the Valencian Community and 31% in La Rioja. The study has revealed an heterogeneous development of suspected OD reporting systems in Spain. Although the trend is positive, only 55% of the AACC have some type of development and 39% have specific software supporting it. Therefore unequal OD recognition rates have been obtained depending on the territory.

    Full Text Available Abstract: With the increase in the prevalence of obesity, non-alcoholic fatty liver disease (NAFLD has become among the leading causes of chronic liver disease in the pediatric age group. Once believed to be a “two-hit process”, it is now clear that the actual pathophysiology of NAFLD is complex and involves multiple pathways. Moreover, NAFLD is not always benign, and patients with non-alcoholic steatohepatitis (NASH are at increased risk of developing advanced stages of liver disease. It has also been shown that NAFLD is not only a liver disease, but is also associated with multiple extrahepatic manifestations, including cardiovascular diseases, type 2 diabetes, and low bone mineral density. Although the data is scarce in the pediatric population, some studies have suggested that long-term mortality and the requirement of liver transplantation will continue to increase in patients with NAFLD. More studies are needed to better understand the natural history of NAFLD, especially in the pediatric age group.

    Context Cystic fibrosis (CF) is the most widespread autosomal recessive genetic disorder that limits life expectation amongst the Caucasian population. As the median survival has increased related to early multidisciplinary intervention, other manifestations of CF have emergedespecially for the broad spectrum of hepatobiliary involvement. The present study reviews the existing literature on liver disease in cystic fibrosis and describes the key issues for an adequate clinical evaluation and management of patients, with a focus on the pathogenetic, clinical and diagnostic-therapeutic aspects of liver disease in CF. Evidence Acquisition A literature search of electronic databases was undertaken for relevant studies published from 1990 about liver disease in cystic fibrosis. The databases searched were: EMBASE, PubMed and Cochrane Library. Results CF is due to mutations in the gene on chromosome 7 that encodes an amino acidic polypeptide named CFTR (cystic fibrosis transmembrane regulator). The hepatic manifestations include particular changes referring to the basic CFTR defect, iatrogenic lesions or consequences of the multisystem disease. Even though hepatobiliary disease is the most common non-pulmonary cause ofmortalityin CF (the third after pulmonary disease and transplant complications), only about the 33%ofCF patients presents clinically significant hepatobiliary disease. Conclusions Liver disease will have a growing impact on survival and quality of life of cystic fibrosis patients because a longer life expectancy and for this it is important its early recognition and a correct clinical management aimed atdelaying the onset of complications. This review could represent an opportunity to encourage researchers to better investigate genotype-phenotype correlation associated with the development of cystic fibrosis liver disease, especially for non-CFTR genetic polymorphisms, and detect predisposed individuals. Therapeutic trials are needed to find strategies of

    2015 marks the 27th year that the Lyme Disease Diagnostic Center, located in New York State in the United States, has provided care for patients with suspected or established deer tick-transmitted infections. There are five deer tick-transmitted infectious in this geographic area of which Lyme disease is the most common.For patients with erythema migrans, we do not obtain any laboratory testing. However, if the patient is febrile at the time of the visit or reports rigors and high-grade fevers, we consider the possibility of a co-infection and order pertinent laboratory tests.Our preferred management for Lyme disease-related facial palsy and/or radiculopathy is a 2-week course of doxycycline. Patients who are hospitalized for Lyme meningitis are usually treated at least initially with ceftriaxone. We have not seen convincing cases of encephalitis or myelitis solely due to Borrelia burgdorferi infection in the absence of laboratory evidence of concomitant deer tick virus infection (Powassan virus). We have also never seen Lyme encephalopathy or a diffuse axonal peripheral neuropathy and suggest that these entities are either very rare or nonexistent.We have found that Lyme disease rarely presents with fever without other objective clinical manifestations. Prior cases attributed to Lyme disease may have overlooked an asymptomatic erythema migrans skin lesion or the diagnosis may have been based on nonspecific IgM seroreactivity. More research is needed on the appropriate management and significance of IgG seropositivity in asymptomatic patients who have no history of Lyme disease.

    The diagnosis of non-alcoholic steatohepatitis and fibrosis staging are central to non-alcoholic fatty liver disease assessment. We evaluated multiparametric magnetic resonance in the assessment of non-alcoholic steatohepatitis and fibrosis using histology as standard in non-alcoholic fatty liver disease. Seventy-one patients with suspected non-alcoholic fatty liver disease were recruited within 1 month of liver biopsy. Magnetic resonance data were used to define the liver inflammation and fibrosis score (LIF 0-4). Biopsies were assessed for steatosis, lobular inflammation, ballooning and fibrosis and classified as non-alcoholic steatohepatitis or simple steatosis, and mild or significant (Activity ≥2 and/or Fibrosis ≥2 as defined by the Fatty Liver Inhibition of Progression consortium) non-alcoholic fatty liver disease.

    Nonalcoholic fatty liver disease (NAFLD) is defined as the presence of hepatic fat accumulation after the exclusion of other causes of hepatic steatosis, including other causes of liver disease, excessive alcohol consumption, and other conditions that may lead to hepatic steatosis. NAFLD encompasses a broad clinical spectrum ranging from nonalcoholic fatty liver to nonalcoholic steatohepatitis (NASH), advanced fibrosis, cirrhosis, and finally hepatocellular carcinoma (HCC). NAFLD is the most common liver disease in the world and NASH may soon become the most common indication for liver transplantation. Ongoing persistence of obesity with increasing rate of diabetes will increase the prevalence of NAFLD, and as this population ages, many will develop cirrhosis and end-stage liver disease. There has been a general increase in the prevalence of NAFLD, with Asia leading the rise, yet the United States is following closely behind with a rising prevalence from 15% in 2005 to 25% within 5 years. NAFLD is commonly associated with metabolic comorbidities, including obesity, type II diabetes, dyslipidemia, and metabolic syndrome. Our understanding of the pathophysiology of NAFLD is constantly evolving. Based on NAFLD subtypes, it has the potential to progress into advanced fibrosis, end-stage liver disease and HCC. The increasing prevalence of NAFLD with advanced fibrosis, is concerning because patients appear to experience higher liver-related and non-liver-related mortality than the general population. The increased morbidity and mortality, healthcare costs and declining health related quality of life associated with NAFLD makes it a formidable disease, and one that requires more in-depth analysis.

    Full Text Available The liver has become an increasingly interesting target for oligonucleotide therapy. Mutations of the gene encoding transthyretin (TTR, expressed in vast amounts by the liver, result in a complex degenerative disease, termed familial amyloid polyneuropathy (FAP. Misfolded variants of TTR are linked to the establishment of extracellular protein deposition in various tissues, including the heart and the peripheral nervous system. Recent progress in the chemistry and formulation of antisense (ASO and small interfering RNA (siRNA designed for a knockdown of TTR mRNA in the liver has allowed to address the issue of gene-specific molecular therapy in a clinical setting of FAP. The two therapeutic oligonucleotides bind to RNA in a sequence specific manner but exploit different mechanisms. Here we describe major developments that have led to the advent of therapeutic oligonucleotides for treatment of TTR-related disease.

    The clinical application of radiofrequency tumor ablation in primary liver tumors and metastatic liver disease is rapidly growing because this technique has proven to be simple, safe, and effective in first clinical studies. Most of the patients with malignant liver disease are not candidates for surgical resection due localisation or comorbidity, so radiofrequency therapy offers a good alternative for inoperable patients. With this method, high frequency alternating current is delivered to tissue via a needle electrode, the produced heat leads to coagulation necrosis. The largest focus of necrosis that can be induced with the currently available systems is approximately 4-5 cm with a single application. The radiofrequency needle is usually placed with US or CT guidance. For follow up examinations CT and MRI can be used, they proved to be equally accurate in the assessment of treatment response.

    Evidence suggests that cystic fibrosis liver disease (CFLD) does not affect mortality or morbidity in patients with cystic fibrosis (CF). The importance of gender and age in outcome in CF makes selection of an appropriate comparison group central to the interpretation of any differences in mortality and morbidity in patients with CFLD.

    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.

    Nonalcoholic fatty liver disease (NAFLD) is a frequent cause of chronic liver diseases, ranging from simple steatosis to nonalcoholic steatohepatitis (NASH)-related liver cirrhosis. Although liver biopsy is still the gold standard for the diagnosis of NAFLD, especially for the diagnosis of NASH, imaging methods have been increasingly accepted as noninvasive alternatives to liver biopsy. Ultrasonography is a well-established and cost-effective imaging technique for the diagnosis of hepatic steatosis, especially for screening a large population at risk of NAFLD. Ultrasonography has a reasonable accuracy in detecting moderate-to-severe hepatic steatosis although it is less accurate for detecting mild hepatic steatosis, operator-dependent, and rather qualitative. Computed tomography is not appropriate for general population assessment of hepatic steatosis given its inaccuracy in detecting mild hepatic steatosis and potential radiation hazard. However, computed tomography may be effective in specific clinical situations, such as evaluation of donor candidates for hepatic transplantation. Magnetic resonance spectroscopy and magnetic resonance imaging are now regarded as the most accurate practical methods of measuring liver fat in clinical practice, especially for longitudinal follow-up of patients with NAFLD. Ultrasound elastography and magnetic resonance elastography are increasingly used to evaluate the degree of liver fibrosis in patients with NAFLD and to differentiate NASH from simple steatosis. This article will review current imaging methods used to evaluate hepatic steatosis, including the diagnostic accuracy, limitations, and practical applicability of each method. It will also briefly describe the potential role of elastography techniques in the evaluation of patients with NAFLD. PMID:24966609

    Nutrition has a profound effect on chronic liver disease, especially non-alcoholic fatty liver disease (NAFLD). Most observational studies and clinical trials have focussed on the effects of total energy intake, or the intake of individual macronutrients and certain micronutrients, such as vitamin D, on liver disease. Although these studies have shown the importance of nutrition on hepatic outcomes, there is not yet any unifying framework for understanding the relationship between diet and liver disease. The Geometric Framework for Nutrition (GFN) is an innovative model for designing nutritional experiments or interpreting nutritional data that can determine the effects of nutrients and their interactions on animal behaviour and phenotypes. Recently the GFN has provided insights into the relationship between dietary energy and macronutrients on obesity and ageing in mammals including humans. Mouse studies using the GFN have disentangled the effects of macronutrients on fatty liver and the gut microbiome. The GFN is likely to play a significant role in disentangling the effects of nutrients on liver disease, especially NAFLD, in humans. Copyright © 2017 European Association for the Study of the Liver.

    Much information in the field of liver research has been gained by dynamic isotope studies. Clinically, these studies can help to settle selection criteria for different types of surgical shunt, which relieve the complications of portal hypertension. By performing splenoportoscintigraphy, splenic and portal vein thrombosis can be easily and safely excluded. So-called hypoxaemia of cirrhosis can most easily be diagnosed. Suprahepatic caval vein obstruction in a patient with cryptogenic liver disease is easily excluded by a radionuclide cavogram after injection of pertechnetate into a foot vein.

    The aim of this study was to evaluate the proportion of suspected heart failure patients with significant valvular heart disease. Early diagnosis of valve disease is essential as delay can limit treatment and negatively affect prognosis for undiagnosed patients. The prevalence of unsuspected valve disease in the community is uncertain. We prospectively evaluated 79 043 patients, between 2001 and 2011, who were referred to a community open access echocardiography service for suspected heart failure. All patients underwent a standard transthoracic echocardiogram according to British Society of Echocardiography guidelines. Of the total number, 29 682 patients (37.5%) were diagnosed with mild valve disease, 8983 patients (11.3%) had moderate valve disease and 2134 (2.7%) had severe valve disease. Of the total number of patients scanned, the prevalence of aortic stenosis, aortic regurgitation, mitral stenosis, mitral regurgitation was 10%, 8.4%, 1%, and 12.5% respectively. 18% had tricuspid regurgitation. 5% had disease involving one or more valves. Of patients with suspected heart failure in the primary care setting, a significant proportion have important valvular heart disease. These patients are at high risk of future cardiac events and will require onward referral for further evaluation. We recommend that readily available community echocardiography services should be provided for general practitioners as this will result in early detection of valve disease.

    The use of natural remedies for the treatment of liver diseases has a long history, starting with the Ayurvedhic treatment, and extending to the Chinese, European and other systems of traditional medicines. The 21st century has seen a paradigm shift towards therapeutic evaluation of herbal products in liver diseases by carefully synergizing the strengths of the traditional systems of medicine with that of the modern concept of evidence-based medicinal evaluation, standardization of herbal products and randomized placebo controlled clinical trials to support clinical efficacy. The present review provides the status report on the scientific approaches made to herbal preparations used in Indian systems of medicine for the treatment of liver diseases. In spite of the availability of more than 300 preparations for the treatment of jaundice and chronic liver diseases in Indian systems of medicine using more than 87 Indian medicinal plants, only four terrestrial plants have been scientifically elucidated while adhering to the internationally acceptable scientific protocols. In-depth studies have proved Sylibum marianum to be anti-oxidative, antilipidperoxidative, antifibrotic, anti-inflammatory, immunomodulating and liver regenerative. Glycyrrhiza glabra has been shown to be hepatoprotective and capable of inducing an indigenous interferon. Picrorhiza kurroa is proved to be anti-inflammatory, hepatoprotective and immunomodulatory. Extensive studies on Phyllanthus amarus have confirmed this plant preparation as being anti-viral against hepatitis B and C viruses, hepatoprotective and immunomodulating, as well as possessing anti-inflammatory properties. For the first time in the Indian systems of medicine, a chemo-biological fingerprinting methodology for standardization of P. amarus preparation has been patented.

    Nonalcoholic fatty liver disease (NAFLD) is the most common cause of chronic liver disease in the industrialized world. The prevalence of NAFLD is increasing, becoming a substantial public health burden. NAFLD includes a broad spectrum of disorders, from simple conditions such as steatosis to severe manifestations such as fibrosis and cirrhosis. The relationship of NAFLD with metabolic alterations such as type 2 diabetes is well described and related to insulin resistance, with NAFLD being recognized as the hepatic manifestation of metabolic syndrome. However, NAFLD may also coincide with endocrine diseases such as polycystic ovary syndrome, hypothyroidism, growth hormone deficiency or hypercortisolism. It is therefore essential to remember, when discovering altered liver enzymes or hepatic steatosis on radiological exams, that endocrine diseases can cause NAFLD. Indeed, the overall prognosis of NAFLD may be modified by treatment of the underlying endocrine pathology. In this review, we will discuss endocrine diseases that can cause NALFD. Underlying pathophysiological mechanisms will be presented and specific treatments will be reviewed.

    The aim of this work was to assess the value of capsule enteroscopy in the diagnosis of patients with suspected Crohn's Disease (CD). Methods. This was a retrospective study in a single tertiary care centre involving patients undergoing capsule enteroscopy for suspected CD. Patients taking nonsteroidal anti inflammatory drugs during the thirty preceding days or with a follow-up period of less than six months were excluded. Results. Seventy eight patients were included. The endoscopic findings included mucosal breaks in 50%, ulcerated stenosis in 5%, and villous atrophy in 4%. The diagnosis of CD was established in 31 patients. The sensitivity, specificity, positive and negative predictive value of the endoscopic findings were 93%, 80%, 77%, and 94%, respectively. Capsule retention occurred in four patients (5%). The presence of ulcerated stenosis was significantly more frequent in patients with positive inflammatory markers. The diagnostic yield of capsule enteroscopy in patients with negative ileoscopy was 56%, with a diagnostic acuity of 93%. Small bowel capsule endoscopy is a safe and valid technique for assessing patients with suspected CD. Capsule retention is more frequent in patients with positive inflammatory markers. Patients with negative ileoscopy and suspected CD should be submitted to capsule enteroscopy.

    Nonalcoholic fatty liver disease (NAFLD) is the most prevalent liver condition in the West. The prevalence and severity of NAFLD is higher and the prognosis worse in patients with psoriasis. The pathogenic link between psoriasis and NAFLD is chronic inflammation and peripheral insulin resistance, a common finding in diseases associated with psoriasis. NAFLD should therefore be ruled out during the initial evaluation of patients with psoriasis, in particular if they show signs of metabolic syndrome and require systemic treatment. Concomitant psoriasis and NAFLD and the likelihood of synergy between them place limitations on general recommendations and treatment for these patients given the potential for liver toxicity. As hepatotoxic risk is associated with some of the conventional drugs used in this setting (e.g., acitretin, methotrexate, and ciclosporin), patients prescribed these treatments should be monitored as appropriate. Anti-tumor necrosis factor agents hold the promise of potential benefits based on their effects on the inflammatory process and improving peripheral insulin resistance. However, cases of liver toxicity have also been reported in relation to these biologics. No evidence has emerged to suggest that anti-p40 or anti-interleukin 17 agents provide benefits or have adverse effects. Copyright © 2017 AEDV. Publicado por Elsevier España, S.L.U.

    In the last years new evidence has accumulated on nonalcoholic fatty liver disease (NAFLD) challenging the paradigms that had been holding the scene over the previous 30 years. NAFLD has such an epidemic prevalence as to make it impossible to screen general population looking for NAFLD cases. Conversely, focusing on those cohorts of individuals exposed to the highest risk of NAFLD could be a more rational approach. NAFLD, which can be diagnosed with either non-invasive strategies or through liver biopsy, is a pathogenically complex and clinically heterogeneous disease. The existence of metabolic as opposed to genetic-associated disease, notably including ”lean NAFLD” has recently been recognized. Moreover, NAFLD is a systemic condition, featuring metabolic, cardiovascular and (hepatic/extra-hepatic) cancer risk. Among the clinico-laboratory features of NAFLD we discuss hyperuricemia, insulin resistance, atherosclerosis, gallstones, psoriasis and selected endocrine derangements. NAFLD is a precursor of type 2 diabetes (T2D) and metabolic syndrome and progressive liver disease develops in T2D patients in whom the course of disease is worsened by NAFLD. Finally, lifestyle changes and drug treatment options to be implemented in the individual patient are also critically discussed. In conclusion, this review emphasizes the new concepts on clinical and pathogenic heterogeneity of NAFLD, a systemic disorder with a multifactorial pathogenesis and protean clinical manifestations. It is highly prevalent in certain cohorts of individuals who are thus potentially amenable to selective screening strategies, intensive follow-up schedules for early identification of liver-related and extrahepatic complications and in whom earlier and more aggressive treatment schedules should be carried out whenever possible.

    Full Text Available Background Non-alcoholic fatty liver disease (NAFLD is a growing diagnosed condition which causes a wide spectrum of liver disorders. There is a lot of evidence introducing NAFLD as a risk factor for coronary artery disease (CAD but there is substantial challenge on the independency of this correlation. Objectives The current study aimed to evaluate the prevalence of NAFLD among patients with CAD. Patients and Methods Patients referred for coronary angiography due to suspected coronary heart disease were included in the study. First, the demographic characteristics were extracted. Alanine aminotransferase (ALT, lipid profile and fasting blood glucose were measured and also liver sonography and coronary angiography were performed on all subjects. According to the angiography results, subjects were divided into three groups: 1- normal angiography; 2-mild CAD and 3- sever CAD. The prevalence of suspected NAFLD was evaluated in all of the groups. Suspected NAFLD was defined as elevated ALT accompanied with fatty liver on liver sonography. Results A total of 314 subjects were eligible for the study, out of which 161(51.3% were male and 153 (48.7% female; 236 (75.1% subjects had coronary artery disease and 78 (24.9% subjects had normal coronary arteries. After ranking the subjects according to the degree of coronary artery stenosis; in subjects with normal coronary arteries, 13 subjects (16.7% were suspected of NAFLD; 172 subjects had mild CAD that 17.44% of them were suspected of NAFLD which was not significant compared to the subjects without CAD (P = 0.046. There was a significant difference in the prevalence of suspected NAFLD among the subjects in the sever CAD group based on finding 64 subjects of NAFLD (P = 0.003.

    Fatty liver disease is defined as an abnormal accumulation of lipids into the cytoplasm of hepatocytes. Different kinds of fatty liver diseases are becoming the most important etiologies of end-stage liver disease in the western world. Because fatty liver is a theoretically reversible process, timely and accurate diagnosis is a prerequisite for potential therapeutic options. This work describes major diagnostic methods and discusses particular advantages and disadvantages of various techniques.

    Highlights: • Three US parameters have diagnosis accuracy for the diagnosis of severe fibrosis equal to 66%. • These three signs detect unidentified fibrosis with a predictive positive value of 32%. • It would be an easy way to detect patients with silent chronic liver diseases. - Abstract: Objectives: Chronic liver diseases remain asymptomatic for many years. Consequently, patients are diagnosed belatedly, when cirrhosis is unmasked by lifethreatening complications. We aimed to identify simple ultrasound parameters for the screening of patients with unknown significant chronic liver disease. Methods: Three hundred and twenty seven patients with chronic liver disease, liver biopsy, and ultrasound examination were included in the derivation set. 283 consecutive patients referred for ultrasound examination were included in the validation set; those selected according to the ultrasound parameters identified in the derivation set were then referred for specialized consultation including non-invasive fibrosis tests and ultimately liver biopsy if liver fibrosis was suspected. Results: In the derivation set, three ultrasound parameters were independent predictors of severe fibrosis: liver surface irregularity, spleen length (>110 mm), and demodulation of hepatic veins. The association of ≥2 of the three above parameters provided 49.1% sensitivity and 86.9% specificity. In the validation set, at ≥2 of the three parameters were present in 23 (8%) of the patients. Among these patients, 8 had liver fibrosis (F ≥ 1), 5 had significant fibrosis (F ≥2) and two cirrhosis. Conclusion: The generalized search of three simple ultrasound signs in patients referred for abdominal ultrasound examination may be an easy way to detect those with silent but significant chronic liver disease

    2006-01-01

    Aim: to determine the effectiveness of a new imaging algorithm in the investigation of suspected pulmonary embolism (PE). Materials and methods: A new imaging algorithm for suspected PE was introduced following the installation of a multisection computed tomography (CT) machine at our institution. Before its installation, patients with suspected PE were evaluated with ventilation/perfusion (V/Q) scintigraphy. Subsequently, patients were triaged according to chest radiography (CR) and respiratory history to either lung scintigraphy or CT pulmonary angiography (CTPA). Patients with a normal CR and no history of lung disease were evaluated using perfusion (Q) scintigraphy [ventilation (V) scintigraphy was no longer performed]. Patients with an abnormal CR, asthma or chronic lung disease were evaluated using CTPA. All V/Q images in a continuous 3-year period before the introduction of the new imaging algorithm and all Q images performed in a 3-year period after its introduction were retrospectively reviewed. Imaging reports were categorized into normal, non-diagnostic (low or intermediate probability) or high probability for PE. Patients in the later group who subsequently underwent CTPA, were also reviewed. Results: After the policy change the percentage of normal scintigrams significantly increased (39 to 60%; p < 0.001). There was a non-significant increase in the percentage of high probability scintigrams (15 to 18%; p = 0.716). Overall the diagnostic yield of lung scintigraphy improved significantly (54 to 78%; p < 0.001). Conclusion: the diagnostic performance of lung scintigraphy can be improved by careful triage of patients to either Q scintigraphy or CTPA based on clinical history and CR findings. Q scintigraphy remains a valuable diagnostic test in the investigation of suspected PE in carefully selected patients

    Disease nonalcoholic fatty liver disease (NAFLD) comprises a series of histologically similar to those induced by alcohol consumption in people with very little or no liver damage same. The importance of NAFLD is its high prevalence in our Western societies, from the point of view liver in its progressive evolution from steatosis to steatohepatitis, cirrhosis and liver cancer. During the last decade it has been observed that NAFLD leads to an increased cardiovascular risk with accelerated atherosclerosis and cardiovascular events, the leading cause of morbidity and mortality. This updated January 2016 revision consists of two parts. In this second part, the treatment of NAFLD and its influence on cardiovascular disease and drugs used in the control of cardiovascular risk factors showing a beneficial effect on the liver disease will be reviewed.

  13. Pruritus in chronic cholestatic liver diseases

    Directory of Open Access Journals (Sweden)

    E. V. Vinnitskaya

    2017-01-01

    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.

    The aim of this study was to assess the prognostic value of 64-slice CT angiography (CTA) in patients with known or suspected coronary artery disease (CAD). Sixty-four-slice coronary CTA was performed in 220 patients [mean age 63 {+-} 11 years, 77 (35%) female] with known or suspected CAD. CTA images were analyzed with regard to the presence and number of coronary lesions. Patients were followed-up for the occurrence of the following clinical endpoints: death, nonfatal myocardial infarction, unstable angina, and coronary revascularization. During a mean follow-up of 14 {+-} 4 months, 59 patients (27%) reached at least one of the predefined clinical endpoints. Patients with abnormal coronary arteries on CTA (i.e., presence of coronary plaques) had a 1st-year event rate of 34%, whereas in patients with normal coronary arteries no events occurred (event rate, 0%, p < 0.001). Similarly, obstructive lesions ({>=}50% luminal narrowing) on CTA were associated with a high first-year event rate (59%) compared to patients without stenoses (3%, p < 0.001). The presence of obstructive lesions was a significant independent predictor of an adverse cardiac outcome. Sixty-four-slice CTA predicts cardiac events in patients with known or suspected CAD. Conversely, patients with normal coronary arteries on CTA have an excellent mid-term prognosis. (orig.)

    Clarification of influencing factors is of great importance in suspected occupational liver diseases. Hints are given on the basis of the author's own experience and after critical evaluation of the relevant literature. Most important are: 1) Establishment of a comprehensive working anamnesis with special regard to specific features of the job, exposure patterns, and all working materials; 2) assessment of the hepatotoxic potential of the suspected working material according to the present state of knowledge in working medicine and toxicology; 3) objectification and quantification of the suspected noxious substances at the place of work by means of air analysis and analysis of the biological matter; 4) differential diagnosis in view of possible competitive influencing factors.

    Our investigations were carried out in 139 patients with various types of malignancy. Included in the investigations were 20 patients with primary liver tumor. The interval between scintigraphic examination and the histological verification ranged from 3 days to 1 year. In 62 of the patients histopathology revealed liver metastases, while 77 patients showed no liver involvement. We arrived at the correct diagnosis 'liver metastasis' in 50 out of 2 patientes. Fifty six out of 77 patients without histopathological evidence of liver metastases revealed negative scintigrams. In 18 of 20(90%) patients with focal liver disease correct diagnosis was established. Considering the fact that liver scintigraphy is a non-invasive procedure, it can be recommended as screening method. In connection with sonography and computer tomography liver scintigraphy can undoubtedly improve the diagnostic accuracy in detecting liver metastases and primary liver tumors. (orig./MG) [de

  18. Aetiology and pathogenesis of alcoholic liver disease.

    Lieber, C S

    1993-09-01

    Until the 1960s, liver disease of the alcoholic patient was attributed exclusively to dietary deficiencies. Since then, however, our understanding of the impact of alcoholism on nutritional status has undergone a progressive evolution. Alcohol, because of its high energy content, was at first perceived to act exclusively as 'empty calories' displacing other nutrients in the diet, and causing primary malnutrition through decreased intake of essential nutrients. With improvement in the overall nutrition of the population, the role of primary malnutrition waned and secondary malnutrition was emphasized as a result of a better understanding of maldigestion and malabsorption caused by chronic alcohol consumption and various diseases associated with chronic alcoholism. At the same time, the concept of the direct toxicity of alcohol came to the forefront as an explanation for the widespread cellular injury. Some of the hepatotoxicity was found to result from the metabolic disturbances associated with the oxidation of ethanol via the liver alcohol dehydrogenase (ADH) pathway and the redox changes produced by the generated NADH, which in turn affects the metabolism of lipids, carbohydrates, proteins and purines. Exaggeration of the redox change by the relative hypoxia which prevails physiologically in the perivenular zone contributes to the exacerbation of the ethanol-induced lesions in zone 3. In addition to ADH, ethanol can be oxidized by liver microsomes: studies over the last twenty years have culminated in the molecular elucidation of the ethanol-inducible cytochrome P450IIE1 (CYP2E1) which contributes not only to ethanol metabolism and tolerance, but also to the selective hepatic perivenular toxicity of various xenobiotics. Their activation by CYP2E1 now provides an understanding for the increased susceptibility of the heavy drinker to the toxicity of industrial solvents, anaesthetic agents, commonly prescribed drugs, 'over the counter' analgesics, chemical

    Full Text Available BACKGROUND: For patients with chronic liver disease, different optimal liver stiffness cut-off values correspond to different stages of fibrosis, which are specific for the underlying liver disease and population. AIMS: To establish the normal ranges of liver stiffness in the healthy Chinese population without underlying liver disease. METHODS: This is a prospective cross sectional study of 2,528 healthy volunteers recruited from the general population and the Red Cross Transfusion Center in Hong Kong. All participants underwent a comprehensive questionnaire survey, measurement of weight, height, and blood pressure. Fasting liver function tests, glucose and cholesterol was performed. Abdominal ultrasound and transient elastography were performed on all participants. RESULTS: Of the 2,528 subjects, 1,998 were excluded with either abnormal liver parenchyma on ultrasound, chronic medical condition, abnormal blood tests including liver enzymes, fasting glucose, fasting cholesterol, high body mass index, high blood pressure, or invalid liver stiffness scan. The reference range for the 530 subjects without known liver disease was 2.3 to 5.9 kPa (mean 4.1, SD 0.89. The median liver stiffness was higher in males compared with females (4.3 vs 4.0 kPa respectively, p55 years (p=0.001. CONCLUSIONS: The healthy reference range for liver stiffness in the Chinese population is 2.3 to 5.9 kPa. Female gender and older age group was associated with a lower median liver stiffness.

    Extensive work has been done over recent years to improve the spatial and temporal resolution of electrocardiogram (ECG)-gated cardiac computed tomography (CT). Advances in both hardware and software analysis have enabled the development of non-invasive coronary angiography. However, these high-quality examinations lend themselves to multiple additional applications beyond coronary angiography. In this review, we illustrate and discuss some established and some emerging applications of ECG-gated cardiac CT beyond the assessment of suspected coronary disease, particularly in light of recent recommendations on the appropriate use of this technology.

    To test associations between heart rate variability (HRV), depressed mood, and positive affect in patients with suspected coronary artery disease (CAD). Depression is associated with impaired HRV post acute cardiac events, but evidence in patients with stable coronary artery disease (CAD) is inconsistent. Seventy-six patients (52 men, 24 women; mean age = 61.1 years) being investigated for suspected CAD on the basis of symptomatology and positive noninvasive tests, completed 24-hour electrocardiograms. The Beck Depression Inventory (BDI) was administered, and positive and depressed affect was measured over the study period with the Day Reconstruction Method (DRM). A total of 46 (60.5%) patients were later found to have definite CAD. HRV was analyzed, using spectral analysis. Typical diurnal profiles of HRV were observed, with greater normalized high frequency (HF) and lower normalized low frequency (LF) power in the night compared with the day. BDI depression scores were not consistently associated with HRV. But positive affect was associated with greater normalized HF power (p = .039) and reduced normalized LF power (p = .007) independently of age, gender, medication with beta blockers, CAD status, body mass index, smoking, and habitual physical activity level. In patients with definite CAD, depressed affect assessed using the DRM was associated with reduced normalized HF power and heightened normalized LF power (p = .007) independently of covariates. Relationships between depression and HRV in patients with CAD may depend on affective experience over the monitoring period. Enhanced parasympathetic cardiac control may be a process through which positive affect protects against cardiovascular disease.

    Creutzfeldt-Jakob disease (CJD) and autoimmune encephalitis with antibodies against neuronal surface antigens (NSA-abs) may present with similar clinical features. Establishing the correct diagnosis has practical implications in the management of care for these patients. To determine the frequency of NSA-abs in the cerebrospinal fluid of patients with suspected CJD and in patients with pathologically confirmed (ie, definite) CJD. A mixed prospective (suspected) and retrospective (definite) CJD cohort study was conducted in a reference center for detection of NSA-abs. The population included 346 patients with suspected CJD and 49 patients with definite CJD. Analysis of NSA-abs in cerebrospinal fluid with brain immunohistochemistry optimized for cell-surface antigens was performed. Positive cases in the suspected CJD group were further studied for antigen specificity using cell-based assays. All definite CJD cases were comprehensively tested for NSA-abs, with cell-based assays used for leucine-rich glioma-inactivated 1 (LGI1), contactin-associated protein-like 2 (CASPR2), N-methyl-d-aspartate (NMDA), and glycine (GlY) receptors. Neuronal surface antigens were detected in 6 of 346 patients (1.7%) with rapid neurologic deterioration suggestive of CJD. None of these 6 patients fulfilled the diagnostic criteria for probable or possible CJD. The target antigens included CASPR2, LGI1, NMDAR, aquaporin 4, Tr (DNER [δ/notch-like epidermal growth factor-related receptor]), and an unknown protein. Four of the patients developed rapidly progressive dementia, and the other 2 patients had cerebellar ataxia or seizures that were initially considered to be myoclonus without cognitive decline. The patient with Tr-abs had a positive 14-3-3 test result. Small cell lung carcinoma was diagnosed in the patient with antibodies against an unknown antigen. All patients improved or stabilized after appropriate treatment. None of the 49 patients with definite CJD had NSA-abs. A low, but

    The Society of Radiologists in Ultrasound convened a panel of specialists from a variety of medical disciplines to reach a consensus about the recommended imaging evaluation of painful shoulders with clinically suspected rotator cuff disease. The panel met in Chicago, Ill, on October 18 and 19, 2011, and created this consensus statement regarding the roles of radiography, ultrasonography (US), computed tomography (CT), CT arthrography, magnetic resonance (MR) imaging, and MR arthrography. The consensus panel consisted of two co-moderators, a facilitator, a statistician and health care economist, and 10 physicians who have specialty expertise in shoulder pain evaluation and/or treatment. Of the 13 physicians on the panel, nine were radiologists who were chosen to represent a broad range of skill sets in diagnostic imaging, different practice types (private and academic), and different geographical regions of the United States. Five of the radiologists routinely performed musculoskeletal US as part of their practice and four did not. There was also one representative from each of the following clinical specialties: rheumatology, physical medicine and rehabilitation, orthopedic surgery, and nonoperative sports medicine. The goal of this conference was to construct several algorithms with which to guide the imaging evaluation of suspected rotator cuff disease in patients with a native rotator cuff, patients with a repaired rotator cuff, and patients who have undergone shoulder replacement. The panel hopes that these recommendations will lead to greater uniformity in rotator cuff imaging and more cost-effective care for patients suspected of having rotator cuff abnormality. © RSNA, 2013 PMID:23401583

    Objective: To analyse histomorphological and immunohistochemical analysis of small intestinal biopsies in adults suspected of celiac disease. Study Design: Descriptive study. Place and Duration of Study: Department of Histopathology, Army Medical College, Rawalpindi, from November 2014 to December 2015. Methodology: Fifty cases of small intestinal mucosal biopsies (duodenal and jejunal) were analysed in adult patients aged above 14 years suspected of celiac disease. Their histomorphological data was recorded using Modified Marsh Criteria. Type of intraepithelial lymphocytes was assessed using immunohistochemistry. Intraepithelial lymphocytes were counted both by H and E stain and immunostain CD3 and CD20. Results: Thirty-four percent patients were aged between 21 - 30 years and 22% patients aged between 41 - 50 years. There were 84% (n=42) males. Thirteen (26%) cases showed focal villous atrophy, 32 (64%) cases showed partial villous atrophy and 5 (10%) cases showed complete villous atrophy. Anti-tissue transglutaminase antibody was positive in 21 (42%) cases. CD3 immunomarker was positive for intraepithelial lymphocytes in all 50 cases while CD20 immunomarker showed focal positivity in areas with lymphoid follicle formation. The count of intraepithelial lymphocytes was found to be almost equal (with a difference of 3 - 4 lymphocytes) on both H and E stain and immunostain CD3 and CD20. Conclusion: Males aged 21 - 30 years were the most commonly affected group. The most frequent change in histology was partial villous atrophy along with lymphocytic enteritis. All the intraepithelial lymphocytes were present in crescendo-pattern of distribution. (author)

  10. Non-Alcoholic Fatty Liver Disease in HIV Infection.

    2017-01-01

    Non-alcoholic fatty liver disease is one of the most frequent chronic hepatic conditions worldwide. The spectrum of non-alcoholic fatty liver disease goes from hepatic steatosis to steatohepatitis, cirrhosis, and hepatocellular carcinoma. Risk factors for non-alcoholic fatty liver disease are metabolic, mainly obesity and the accompanying consequences. Treatment and prevention of non-alcoholic fatty liver disease should target those metabolic abnormalities. The frequency of and the factors associated with hepatic steatosis in HIV infection seem to be similar to those reported in the general population, though direct comparisons are lacking. Hepatic steatosis in HIV infection may also be secondary to antiretroviral drugs or HCV-related factors in HCV-coinfected subjects. However, more recent data suggest that hepatic steatosis in HIV infection represents true non-alcoholic fatty liver disease. As such, management of non-alcoholic fatty liver disease in HIV infection should follow the same principles as in the general population.

    There are many limitations for conducting liver disease research in human beings due to the high cost and potential ethical issues. For this reason, conducting a study that is difficult to perform in humans using appropriate animal models, can be beneficial in ascertaining the pathological physiology, and in developing new treatment modalities. However, it is difficult to determine the appropriate animal model which is suitable for research purposes, since every patient has different and diverse clinical symptoms, adverse reactions, and complications due to the pathological physiology. Also, it is not easy to reproduce identically various clinical situations in animal models. Recently, the Guide for the Care and Use of Laboratory Animals has tightened up the regulations, and therefore it is advisable to select the appropriate animals and decide upon the appropriate quantities through scientific and systemic considerations before conducting animal testing. Therefore, in this review article the authors examined various white rat animal testing models and determined the appropriate usable rat model, and the pros and cons of its application in liver disease research. The authors believe that this review will be beneficial in selecting proper laboratory animals for research purposes.

  12. Cellular Mechanisms of Liver Regeneration and Cell-Based Therapies of Liver Diseases

    Directory of Open Access Journals (Sweden)

    Irina V. Kholodenko

    2017-01-01

    Full Text Available The emerging field of regenerative medicine offers innovative methods of cell therapy and tissue/organ engineering as a novel approach to liver disease treatment. The ultimate scientific foundation of both cell therapy of liver diseases and liver tissue and organ engineering is delivered by the in-depth studies of the cellular and molecular mechanisms of liver regeneration. The cellular mechanisms of the homeostatic and injury-induced liver regeneration are unique. Restoration of the mass of liver parenchyma is achieved by compensatory hypertrophy and hyperplasia of the differentiated parenchymal cells, hepatocytes, while expansion and differentiation of the resident stem/progenitor cells play a minor or negligible role. Participation of blood-borne cells of the bone marrow origin in liver parenchyma regeneration has been proven but does not exceed 1-2% of newly formed hepatocytes. Liver regeneration is activated spontaneously after injury and can be further stimulated by cell therapy with hepatocytes, hematopoietic stem cells, or mesenchymal stem cells. Further studies aimed at improving the outcomes of cell therapy of liver diseases are underway. In case of liver failure, transplantation of engineered liver can become the best option in the foreseeable future. Engineering of a transplantable liver or its major part is an enormous challenge, but rapid progress in induced pluripotency, tissue engineering, and bioprinting research shows that it may be doable.

    Full Text Available Resistance to multidrug therapy (MDT is one of the complications in the treatment of Hansen’s disease/Morbus Hansen (MH. There are two types of resistancy, which are primary and secondary. MDT-multibacillary (MB resistance must be suspected when no clinical improvement and the acid-fast bacilli (AFB index is not reduced after 12 months of therapy. A 28-year-old woman with paresthesia on her face, arms and legs since 2.5 years ago, accompanied by thickening of the right posterior tibial nerve. The AFB examination showed a bacteriological index (BI of 15/6 and morphological index (MI of 0.50%. The second case, a 42-year-old man came with paresthetic lesions on his face, chest, back, both arms and legs since 2 years ago, accompanied by thickening of ulnar and lateral peroneal nerve. The BI was 12/5 and the MI was 0.40%. Both patients were diagnosed with borderline lepromatous type of MH and received MDT-MB for 12 months. Diagnosis of suspected resistance was established because no clinical improvement or any significant decrease of AFB index after completing the MDT treatment. The patients had secondary resistance after polymerase chain reaction evaluation showed that they were still rifampicin-sensitive. There was clinical improvement and significant decrease in FAB index after the patients continued the MDT-MB treatment with 600 mg additional rifampicin. The diagnosis of bacterial resistance should be made based on clinical evaluation before completion of treatment. Based on the two case reports, the resistance suspected may be secondary. Treatment using additional regimen can be initiated once the resistance has been proven.

    Full Text Available AbstractBackground:Guidelines recommend that in suspected stable coronary artery disease (CAD, a clinical (non-invasive evaluation should be performed before coronary angiography.Objective:We assessed the efficacy of patient selection for coronary angiography in suspected stable CAD.Methods:We prospectively selected consecutive patients without known CAD, referred to a high-volume tertiary center. Demographic characteristics, risk factors, symptoms and non-invasive test results were correlated to the presence of obstructive CAD. We estimated the CAD probability based on available clinical data and the incremental diagnostic value of previous non-invasive tests.Results:A total of 830 patients were included; median age was 61 years, 49.3% were males, 81% had hypertension and 35.5% were diabetics. Non-invasive tests were performed in 64.8% of the patients. At coronary angiography, 23.8% of the patients had obstructive CAD. The independent predictors for obstructive CAD were: male gender (odds ratio [OR], 3.95; confidence interval [CI] 95%, 2.70 - 5.77, age (OR for 5 years increment, 1.15; CI 95%, 1.06 - 1.26, diabetes (OR, 2.01; CI 95%, 1.40 - 2.90, dyslipidemia (OR, 2.02; CI 95%, 1.32 - 3.07, typical angina (OR, 2.92; CI 95%, 1.77 - 4.83 and previous non-invasive test (OR 1.54; CI 95% 1.05 - 2.27.Conclusions:In this study, less than a quarter of the patients referred for coronary angiography with suspected CAD had the diagnosis confirmed. A better clinical and non-invasive assessment is necessary, to improve the efficacy of patient selection for coronary angiography.

  15. The Role of Oxidative Stress and Antioxidants in Liver Diseases

    2015-11-01

    Full Text Available A complex antioxidant system has been developed in mammals to relieve oxidative stress. However, excessive reactive species derived from oxygen and nitrogen may still lead to oxidative damage to tissue and organs. Oxidative stress has been considered as a conjoint pathological mechanism, and it contributes to initiation and progression of liver injury. A lot of risk factors, including alcohol, drugs, environmental pollutants and irradiation, may induce oxidative stress in liver, which in turn results in severe liver diseases, such as alcoholic liver disease and non-alcoholic steatohepatitis. Application of antioxidants signifies a rational curative strategy to prevent and cure liver diseases involving oxidative stress. Although conclusions drawn from clinical studies remain uncertain, animal studies have revealed the promising in vivo therapeutic effect of antioxidants on liver diseases. Natural antioxidants contained in edible or medicinal plants often possess strong antioxidant and free radical scavenging abilities as well as anti-inflammatory action, which are also supposed to be the basis of other bioactivities and health benefits. In this review, PubMed was extensively searched for literature research. The keywords for searching oxidative stress were free radicals, reactive oxygen, nitrogen species, anti-oxidative therapy, Chinese medicines, natural products, antioxidants and liver diseases. The literature, including ours, with studies on oxidative stress and anti-oxidative therapy in liver diseases were the focus. Various factors that cause oxidative stress in liver and effects of antioxidants in the prevention and treatment of liver diseases were summarized, questioned, and discussed.

    The application of EMI units for diagnosis of the liver diseases was studied. Cases in this report were included 16 normal cases, 20 metastatic liver cancer, 20 primary liver cancer and 9 liver cysts. EMI units of 320 x 320 matrix were changed to those of 64 x 64 matrix, averaging of 25 points with another computer system. Using the EMI units of 64 x 64 matrix, digital expression, histogram, and MAP expression in the resion of interest (R.O.I.) were printed out automatically. Two kinds of R.O.I. were set up, that is, R.O.I.-1 was the area of the liver including hepatic lesions, and R.O.I.-2 was the area of the spleen. The peak values of the EMI units were 0.23 +- 3.51 in the liver cysts, 13.9 +- 3.37 in the metastatic liver cancers, 16.9 +- 3.75 in the primary liver cancers, and 24.7 +- 2.98 in the normal cases. The peak value of the EMI units in the liver cysts was clearly separated from others, but in the primary and metastatic cancers and normal cases, the peak values were overlapped. The EMI units of normal livers were higher than those of spleens, and those of hepatic lesions were lower, in the same slice of the CT scans. Therefore, if the EMI units of liver were lower than those of spleen, it was thought that the presence of hepatic abnormality was suspected. Correct diagnosis rates were 56.9% in the readings of MAP expressions, 67.7% in CT images, and 76.9% in both. In conclusion, correct diagnosis rate of CT images becomes better when combined with the expressions of EMI units. (author)

    Full Text Available Severe liver diseases such as liver failure and acute decompensated cirrhosis have critical conditions and high mortality rates, and the prognosis of such patients is closely associated with early warning, timely dynamic assessment, and comprehensive and effective therapy. The patients require a series of effective clinical management measures for elimination of causative factors, organ support, and prevention and treatment of complications. Medical treatment-artificial liver-liver transplantation is an important modality for severe liver diseases. Granulocyte colony-stimulating factor, stem cell therapy, and bioartificial liver have a promising future, while there are still controversies over non-selective β-blocker. This article reviews the hotspots in the clinical management of severe liver diseases.

    2002-01-01

    Purpose: Although there is considerable epidemiologic evidence for a relationship between plasma homocysteine (Hcy) levels and coronary artery disease (CAD), not all studies, especially prospective ones have shown such a relationship. The purpose of this study was to investigate a possible association between Hcy plasma levels and myocardial perfusion defect by SPECT in patients suspected CAD. Methods and Materials: A cohort of 238 patients suspected CAD (age: 60.65±10.43, male to female: 172: 66) was examined for Hcy, tetrahydrofolic acid (FH4), vitamine B12 and coronary angiography (CAG). Furthermore, 42 patients also underwent 99m Tc-MIBI myocardial perfusion images (MPI) to assess the myocardial perfusion. Results: There were 69 patients with normal CAG and 63, 60, 42 and 4 patients with 1 vessel, two vessel, 3 vessel and left main coronary stenosis. The plasma Hcy of this group was significantly increased, p 0.05. In patients with >=3 segments myocardial perfusion defect, 10 of them had normal Hcy, and 7 with hyperhomocysteinemia, in patients with 0.05). Conclusion: Our data may indicate that hyperhomocysteinemia represents an independent risk factor in patients with high possibility of CAD rather than a mark of myocardial ischemia or coronary stenosis

    The role of non-invasive imaging techniques in the evaluation of patients with suspected or known coronary artery disease (CAD) has increased exponentially over the past decade. The traditionally available imaging modalities, including nuclear imaging, stress echocardiography and magnetic resonance imaging (MRI), have relied on detection of CAD by visualisation of its functional consequences (i.e. ischaemia). However, extensive research is being invested in the development of non-invasive anatomical imaging using computed tomography or MRI to allow detection of (significant) atherosclerosis, eventually at a preclinical stage. In addition to establishing the presence of or excluding CAD, identification of patients at high risk for cardiac events is of paramount importance to determine post-test management, and the majority of non-invasive imaging tests can also be used for this purpose. The aim of this review is to provide an overview of the available non-invasive imaging modalities and their merits for the diagnostic and prognostic work-up in patients with suspected or known CAD.

    Full Text Available 72 1024x768 Pemphigus vulgaris (PV is a group of vesicobullous disease affecting skin and mucous membranes. PV is associated with autoimmune diseases, characterized by binding of IgG autoantibodies to desmoglein 3. PV lesion is a thin-walled bulla arising on the skin or mucosa. Oral mucous bulla are fragile and easily breakdown, forming irreguler ulcers. There are several factors that trigger PV, including genetic factors, age, drugs and food. This paper aimed to report treatment of suspected pemphigus vulgaris in elderly patient with history of chronic diseases. A 75-year-old woman with 2 months history of bulla formation on skin and history of persistent oral ulceration. Ulcers were covered with fibrin and erosive erythematous on labial, buccal and gingival mucosa. History of hypertension, diabetes mellitus and hepatitis was revealed. Routine complete blood count showed thrombocytopenia. Diagnosis was confirmed by anamnesis, clinical examination and complete blood investigation. PV should be distinguished from other vesicobullous disease. Systemic corticosteroid was given concurrently with hepato-protector, mouthwash, supportive therapy and topical lip cream. Bulla on skin and persistent erosive ulcers of the oral mucosa are the manifestations of PV. Elderly patient with history of chronic diseases showed a complex care of PV requiring more intensive and comprehensive treatment.DOI: 10.14693/jdi.v20i1.129

    Full Text Available As the etiology of hepatocellular carcinoma (HCC has been changing, the incidence of HCC related to nonalcoholic fatty liver disease (NAFLD is gradually increasing in developed countries in Europe and America and some countries in Asia. This article introduces the close association between NAFLD and HCC, risk factors, clinicopathological features, and prevention and screening, and points out that although the incidence of NAFLD is not as high as that of hepatitis B- or hepatitis C-related HCC, there are a large absolute number of NAFLD patients, especially the high-risk patients with diabetes and obesity, or liver fibrosis/cirrhosis, due to a huge base number of NAFLD patients. NAFLD-related HCC is commonly seen in the elderly with various comorbidities and a poor prognosis. This article also points out that the prevention should focus on the effective treatment of NAFLD. The strict screening of high-risk population is the strategy for the diagnosis of early-stage HCC. At present, the sensitivity of alpha-fetoprotein is relatively low, and imaging examinations including computed tomography are the main screening methods; however, there are no measures for early warning of NAFLD-related HCC.

    Doppler echocardiography (Echo) is a non-invasive method of excellent accuracy to screen portopulmonary hypertension (PPH) and to assess intrapulmonary shunts (IPS) in chronic liver disease (CLD). In the past decade, Echo proved to play a fundamental role in the diagnosis of cirrhotic cardiomyopathy (CCM). To perform a systematic review of relevant articles on the subject 'Echo in CLD'. In November 2011, a systematic review was performed in the PubMed, LILACS and SciELO databases, and the characteristics of the studies selected were reported. The search based on descriptors and free terms obtained 204 articles (179 in Pubmed, 21 in LILACS, and 1 in SciELO). Of those 204 articles, 22 were selected for systematic review. A meta-analysis could not be performed because of the heterogeneity of the articles. Echo should be part of CLD stratification for screening PPH, IPS and CCM, because, most of the time, such complications are diagnosed only when patients are already waiting for a liver transplant.

    2013-03-01

    Chronic liver disease (CLD) and several related extrahepatic manifestations such as hepatic osteodystrophy are associated with deficiency of vitamin D, which has therefore been suggested as therapeutic target. Vitamin D undergoes hepatic 25-hydroxylation, rendering the liver critical to the metabolic activation of this vitamin. Vitamin D deficiency is highly prevalent in CLD patients, and vitamin D levels are inversely related to the severity of CLD. Declining levels of carrier proteins such as albumin and vitamin D-binding protein might also be critical in CLD. Intervention studies report improvements of CLD following supplementation, and benefits to health outcomes in particular with respect to hepatitis C virus infection have recently been documented. We discuss vitamin D sources, functions and metabolism with a focus on the inherent complications of analytical measurements, such as the interference of 25-hydroxyvitamin D and 1,25-dihydroxyvitamin D C-3 epimers. Global discrepancies in the definition of optimal serum 25-hydroxyvitamin D levels are covered, and the prevalence of vitamin D deficiency in CLD is reviewed. We also address the functional mechanisms underlying this deficiency, and refer to associations between genetic variation in vitamin D metabolism and CLD. Lastly, we consider the health implications of a vitamin D deficiency in CLD and consider therapeutic options. Herein, we focus on the epidemiological and functional relationships between vitamin D deficiency and CLD, followed by a discussion of the potential implications for therapeutic interventions. © 2012 John Wiley & Sons A/S.

    Cell proliferative activity in the liver tissue obtained in 50 cases by liver biopsy, was analyzed using in vitro labeling of /sup 3/H-thymidine autoradiography. The proliferating cells were found to be located mainly in the periportal areas of the lobules. The mean labeling indices of the liver cells were 0.06 % in chronic hepatitis in its active form, 0.05 % in pre-cirrhosis of the liver, 0.03 % in liver cirrhosis, 0.02 % in chronic hepatitis in an inactive form and 0.018 % in acute hepatitis at the restoractive stage. The labeling indices of the liver parenchymal cells of each specimen studied were very low being at most 0.2 %. On the other hand, when the serum AFP was analyzed by radioimmunoassay technique in 185 patients with various liver diseases, level of the mean serum AFP in each group of the liver diseases was found to correspond to that of the proliferative activity of the liver cells in its respective group. From these data it was suggested that the proliferative activity of the liver cells in various liver diseases, with the exception of hepatomas, was closely related to release of AFP into the serum.

    The patients with end stage renal disease (ESRD) are at greater risk of acquiring chronic hepatitis B or C and subsequently development of liver disease. The aim of the study was to assess liver fibrosis by transient elastography (TE) and look for factors associated with change in liver stiffness measurement (LSM) with one session of hemodialysis (HD). Consecutive ESRD patients on maintenance hemodialysis (MHD) with suspected liver disease were enrolled. They underwent LSM by TE before and after one session of HD. Bioelectric impedance analysis was done to evaluate the volume status at the time of TE. Sixty-eight patients with mean age of 40 ± 14 years were included. There was a significant reduction in LSM after HD (18.5 [95% CI 14.8-23.1] vs. 11.2 [95% CI 8.8-13.7] kPa, p  or  2.5 L (8.6 [95% CI 5.7-11.5] vs. 5.1 [95% CI 2.9-7.5], p = 0.05). In 18 patients who underwent liver biopsy, LSM after HD performed better at detecting significant fibrosis, with area under receiver operating characteristics curve 0.71 [95% CI 0.46-0.97], versus 0.64 [95% CI 0.38-0.90], respectively. An LSM value of 12.2 kPa after HD was 71% sensitive and 74% specific for detection of significant fibrosis (≥ F2), while values less than 9 kPa ruled out significant fibrosis with a sensitivity and specificity of 37 and 100%, respectively. LSM by TE decreases significantly after HD in patients with ESRD on long-term MHD. Hence, TE should be done after HD for accurate assessment of liver fibrosis.

    Yellow fever (YF) 17D vaccine is one of the most successful vaccines ever developed. Since 2001, 56 cases of yellow fever vaccine-associated viscerotropic disease (YEL-AVD) have been published in the peer-reviewed literature. Here, we report a new case suspected for YEL-AVD in the Netherlands. Further research is needed to determine the true incidence of YEL-AVD and to clarify host and vaccine-associated factors in the pathogenesis of YEL-AVD. Because of the potential adverse events, healthcare providers should carefully consider vaccination only in people who are truly at risk for YF infection, especially in primary vaccine recipients. © 2014 International Society of Travel Medicine.

    The depth of our knowledge regarding mast cells has widened exponentially in the last 20 years. Once thought to be only important for allergy-mediated events, mast cells are now recognized to be important regulators of a number of pathological processes. The revelation that mast cells can influence organs, tissues, and cells has increased interest in mast cell research during liver disease. The purpose of this review is to refresh the reader's knowledge of the development, type, and location of mast cells and to review recent work that demonstrates the role of hepatic mast cells during diseased states. This review focuses primarily on liver diseases and mast cells during autoimmune disease, hepatitis, fatty liver disease, liver cancer, and aging in the liver. Overall, these studies demonstrate the potential role of mast cells in disease progression.

    As the result of various effects (viruses, metabolic diseases, nutritional factors, toxic agents, autoimmune processes) abnormal liver function, liver steatosis and connective tissue remodeling may develop. Progression of this process is complex including various pathways and a number of factors. The authors summarize the factors involved in the progression of chronic liver disease. They describe the role of cells and the produced inflammatory mediators and cytokines, as well as the relationship between the disease and the intestinal flora. They emphasize the role of oxidative stress, mitochondrial dysfunction and cell death in disease progression. Insulin resistance and micro-elements (iron, copper) in relation to liver damage are also discussed, and genetic and epigenetic aspects underlying disease progression are summarized. Discovery of novel treatment options, assessment of the effectiveness of treatment, as well as the success and proper timing of liver transplantation may depend on a better understanding of the process of disease progression.

    Increased body mass index (BMI), a parameter of total body fat content, is associated with an increased mortality in the general population. However, recent studies have shown a paradoxic relation between BMI and mortality in specific patient populations. This study investigated the association of BMI with long-term mortality in patients with known or suspected coronary artery disease. In a retrospective cohort study of 5,950 patients (mean age 61 +/- 13 years; 67% men), BMI, cardiovascular risk markers (age, gender, hypertension, diabetes, current smoking, angina pectoris, old myocardial infarction, heart failure, hypercholesterolemia, and previous coronary revascularization), and outcome were noted. The patient population was categorized as underweight, normal, overweight, and obese based on BMI according to the World Health Organization classification. Mean follow-up time was 6 +/- 2.6 years. Incidences of long-term mortality in underweight, normal, overweight, and obese were 39%, 35%, 24%, and 20%, respectively. In a multivariate analysis model, the hazard ratio (HR) for mortality in underweight patients was 2.4 (95% confidence interval [CI] 1.7 to 3.7). Overweight and obese patients had a significantly lower mortality than patients with a normal BMI (HR 0.65, 95% CI 0.6 to 0.7, for overweight; HR 0.61, 95% CI 0.5 to 0.7, for obese patients). In conclusion, BMI is inversely related to long-term mortality in patients with known or suspected coronary artery disease. A lower BMI was an independent predictor of long-term mortality, whereas an improved outcome was observed in overweight and obese patients.

    To see the histological outcome of duodenal biopsies done in patients clinically suspected of celiac disease. Study Design: Prospective descriptive study. Place and Duration of Study: Histopathology Department, Army Medical College Rawalpindi, from 1 Jan 2017 to 30 Jun 2017. Material and Methods: One hundred (100) cases were included in the study. Duodenal biopsies done in patients clinically suspected of celiac disease were included in the study. Inadequate biopsies were excluded from the study. All the normal and abnormal histological features were noted to make the diagnosis. Data was entered and analyzed by using SPSS version 17. Results: Duodenal biopsies of 100 patients, done in clinically suspected cases of celiac disease were analyzed histologically. Out of these 100 cases, 46 cases (46%) showed histological features consistent with celiac disease, while 38 cases (38%) revealed chronic non specific duodenitis, 2 cases (2%) were of giardiasis, while 14 biopsies (14%) were unremarkable with no significant pathology. Conclusion: A significant number of cases clinically suspected of celiac disease may not be showing histological features consistent with celiac disease on duodenal biopsies. Due to the changing presentation of disease, as well as the recognition of a number of potential clinical and histopathological mimics, communication between pathologists and gastroenterologists is essential for appropriate interpretation of duodenal biopsy specimens.

    Liver fibrosis is the excessive accumulation of extracellular matrix proteins such as collagens, which may result in cirrhosis, liver failure, and portal hypertension. In this study, we apply a multimodal nonlinear optical microscopy platform developed to investigate the fibrotic liver diseases in rat models established by performing bile duct ligation (BDL) surgery. The three nonlinear microscopy imaging modalities are implemented on the same sectioned tissues of diseased model sequentially: i.e., second harmonic generation (SHG) imaging quantifies the contents of the collagens, the two-photon excitation fluorescence (TPEF) imaging reveals the morphology of hepatic cells, while coherent anti-Stokes Raman scattering (CARS) imaging maps the distributions of fats or lipids quantitatively across the tissue. Our imaging results show that during the development of liver fibrosis (collagens) in BDL model, fatty liver disease also occurs. The aggregated concentrations of collagen and fat constituents in liver fibrosis model show a certain correlationship between each other.

    Studies suggest that periodontal disease, a source of subclinical and persistent infection, may be associated with various systemic conditions, including liver cirrhosis. The aim of this study was to examine the literature and determine the relationship between periodontal disease and liver cirrhosis and to identify opportunities and directions for future research in this area. A systematic review of English articles in the PubMed, EMBASE, and Scopus databases was conducted using search terms including 'liver cirrhosis', 'end-stage liver disease', 'liver diseases', 'oral health', 'periodontal disease', 'mouth disease', 'gingivitis', and 'periodontitis'. Thirteen studies published between 1981 and 2014 were found to include data on oral health and periodontal disease in cirrhotic patients. Studies indicated an increased incidence of periodontal disease in patients with liver cirrhosis, measured with several different periodontal indices. The reported prevalence of periodontal disease in cirrhosis patients ranged from 25.0% to 68.75% in four studies and apical periodontitis was found in 49%-79% of the patients. One study found that mortality was lower among patients who underwent dental treatment versus non-treated patients. Another study suggested an association between periodontal disease and the progression of liver cirrhosis, but data are sparse and conflicting as to whether periodontal disease is correlated to cirrhosis aetiology and severity. Despite the clinical reality of periodontal disease in liver cirrhosis patients, there are few published studies. Before clinical implications can be addressed, more data on the prevalence of and correlation between periodontal disease and liver cirrhosis aetiology, duration, and progression are needed.

    Paralleling the first 30 years of the Journal of Hepatology we have witnessed huge advances in our understanding of liver disease and physiology. Genetic advances have played no small part in that. Initial studies in the 1970s and 1980s identified the strong major histocompatibility complex associations in autoimmune liver diseases. During the 1990 s, developments in genomic technologies drove the identification of genes responsible for Mendelian liver diseases. Over the last decade, genome-wide association studies have allowed for the dissection of the genetic susceptibility to complex liver disorders, in which also environmental co-factors play important roles. Findings have allowed the identification and elaboration of pathophysiological processes, have indicated the need for reclassification of liver diseases and have already pointed to new disease treatments. In the immediate future genetics will allow further stratification of liver diseases and contribute to personalized medicine. Challenges exist with regard to clinical implementation of rapidly developing technologies and interpretation of the wealth of accumulating genetic data. The historical perspective of genetics in liver diseases illustrates the opportunities for future research and clinical care of our patients.

    Noonan Syndrome (NS) is characterized by short stature, typical facial dysmorphology and congenital heart defects. The incidence of NS is estimated to be between 1:1000 and 1:2500 live births. The syndrome is transmitted as an autosomal dominant trait. In approximately 50% of cases, the disease is caused by missense mutations in the PTPN11 gene on chromosome 12, resulting in a gain of function of the non-receptor protein tyrosine phosphatase SHP-2 protein. Autoimmune Hepatitis (AIH) is a cryptogenic, chronic and progressive necroinflammatory liver disease. Common features of AIH are hypergammaglobulinemia (IgG), presence of circulating autoantibodies, histological picture of interface hepatitis and response to immunosuppressant drugs. Conventional treatment with Prednisone and Azathioprine is effective in most patients. We describe the case of a 6 years-old girl with Noonan Syndrome and Autoimmune Hepatitis type 1. Molecular analysis of PTPN11 gene showed heterozygous mutation c.923A>G (Asn308Ser) in exon 8. Though association between NS and autoimmune disorders is known, this is the second case of association between Noonan Syndrome and Autoimmune Hepatitis type 1 described in literature. In the management of NS, an accurate clinical evaluation would be recommended. When there is a clinical suspicion of autoimmune phenomena, appropriate laboratory tests should be performed with the aim of clarifying whether the immune system is involved in NS. We think that autoimmunity represents a characteristic of NS, even if the etiopathogenesis is still unknown. Copyright © 2015 Elsevier Masson SAS. All rights reserved.

    To evaluate the prognostic value of coronary atherosclerotic burden, assessed by coronary artery calcium (CAC) score, and coronary vascular function, assessed by coronary flow reserve (CFR) in patients with suspected coronary artery disease (CAD). We studied 436 patients undergoing hybrid {sup 82}Rb positron emission tomography/computed tomography imaging. CAC score was measured according to the Agatston method, and patients were categorized into three groups (0, <400, and ≥400). CFR was calculated as the ratio of hyperemic to baseline myocardial blood flow, and it was considered reduced when <2. Follow-up was 94% complete during a mean period of 47±15 months. During follow-up, 17 events occurred (4% cumulative event rate). Event-free survival decreased with worsening of CAC score category (p < 0.001) and in patients with reduced CFR (p < 0.005). At multivariable analysis, CAC score ≥400 (p < 0.01) and CFR (p < 0.005) were independent predictors of events. Including CFR in the prognostic model, continuous net reclassification improvement was 0.51 (0.14 in patients with events and 0.37 in those without). At classification and regression tree analysis, the initial split was on CAC score. For patients with a CAC score < 400, no further split was performed, while patients with a CAC score ≥400 were further stratified by CFR values. Decision curve analyses indicate that the model including CFR resulted in a higher net benefit across a wide range of decision threshold probabilities. In patients with suspected CAD, CFR provides significant incremental risk stratification over established cardiac risk factors and CAC score for prediction of adverse cardiac events. (orig.)

    AIM: The aim of this study was to examine the spectrum of spinal canal disease in patients with known malignancy using magnetic resonance imaging (MRI). MATERIALS AND METHODS: One hundred and fifty-five patients underwent a total of 159 spinal MRI examinations over a three-year period. Patients were examined using a 1.0T magnet and a phased array surface spine coil. Sagittal T1 weighted spin echo and STIR sequences were routinely employed. Axial T1 and T2 weighted spin echo images were obtained at sites of identified pathology. Contrast enhanced sagittal and axial T1 weighted spin echo images were acquired when the unenhanced appearances did not correlate with the clinical findings or when the images suggested intradural or intramedullary disease. RESULTS: Malignant disease affecting the spinal cord or cauda equina was noted in 104/159 (65%) patients (extradural n= 78, intradural n= 20, intramedullary n= 7); one patient had evidence of both intradural and intramedullary deposits. Multiple levels of extradural cord/cauda equina compression were present in 18/78 patients (23%). The thoracic spine was the most frequently affected (74%). Bone elements were the major component of extradural compression in 11/78 patients (14%). Intradural metastases were multiple in 15/20 patients (75%). Four of the six solitary intramedullary metastases were situated in the conus medullaris. CONCLUSION: Magnetic resonance imaging of the entire spine is the investigation of choice in patients with known malignancy and suspected spinal canal disease. Contrast-enhanced images should be acquired when the unenhanced appearances do not correlate with the clinical findings or when they suggest intradural or intramedullary disease. Loughrey, G.J.

    Full Text Available Successful and consistent isolation of primary human hepatocytes remains a challenge for both cell-based therapeutics/transplantation and laboratory research. Several centres around the world have extensive experience in the isolation of human hepatocytes from non-diseased livers obtained from donor liver surplus to surgical requirement or at hepatic resection for tumours. These livers are an important but limited source of cells for therapy or research. The capacity to isolate cells from diseased liver tissue removed at transplantation would substantially increase availability of cells for research. However no studies comparing the outcome of human hepatocytes isolation from diseased and non-diseased livers presently exist. Here we report our experience isolating human hepatocytes from organ donors, non-diseased resected liver and cirrhotic tissue. We report the cell yields and functional qualities of cells isolated from the different types of liver and demonstrate that a single rigorous protocol allows the routine harvest of good quality primary hepatocytes from the most commonly accessible human liver tissue samples.

    The rapid increase in fatty liver disease (FLD) incidence is attributed largely to genetic and lifestyle factors; however, environmental toxicants are a frequently overlooked factor that can modify the effects of more common causes of FLD. Chronic exposure to inorganic arsenic (iAs) is associated with liver disease in humans and animal models, but neither the mechanism of action nor the combinatorial interaction with other disease-causing factors has been fully investigated. Here, we examined...

    Lyme disease is spreading worldwide, with multiple Borrelia species causing a broad range of clinical symptoms that mimic other illnesses. A validated Lyme disease screening questionnaire would be clinically useful for both providers and patients. Three studies evaluated such a screening tool, namely the Horowitz Multiple Systemic Infectious Disease Syndrome (MSIDS) Questionnaire. The purpose was to see if the questionnaire could accurately distinguish between Lyme patients and healthy individuals. Study 1 examined the construct validity of the scale examining its factor structure and reliability of the questionnaire among 537 individuals being treated for Lyme disease. Study 2 involved an online sample of 999 participants, who self-identified as either healthy (N=217) or suffering from Lyme now (N=782) who completed the Horowitz MSIDS Questionnaire (HMQ) along with an outdoor activity survey. We examined convergent validity among components of the scale and evaluated discriminant validity with the Big Five personality characteristics. The third study compared a sample of 236 patients with confirmed Lyme disease with an online sample of 568 healthy individuals. Factor analysis results identified six underlying latent dimensions; four of these overlapped with critical symptoms identified by Horowitz - neuropathy, cognitive dysfunction, musculoskeletal pain, and fatigue. The HMQ showed acceptable levels of internal reliability using Cronbach's coefficient alpha and exhibited evidence of convergent and divergent validity. Components of the HMQ correlated more highly with each other than with unrelated traits. The results consistently demonstrated that the HMQ accurately differentiated those with Lyme disease from healthy individuals. Three migratory pain survey items (persistent muscular pain, arthritic pain, and nerve pain/paresthesias) robustly identified individuals with verified Lyme disease. The results support the use of the HMQ as a valid, efficient, and low

    Computed tomographic studies were performed with special reference to attenuation values (CT number) in 207 cases including 30 of normal controls and 177 of liver diseases. in addition to fatty liver (CT no. 12.2), attenuation values of liver cirrhosis (25.4) was significantly lower (p < 0.001) than normal controls (29.7). In localized hepatic lesions, attenuation values were low in order of primary liver cancer (15.9), metastatic liver cancer (13.5), gallbladder cancer (13.4), liver abscess (10.2) and liver cyst (1.4). Although statistical differences were present among attenuation values, CT had often limited diagnostic value in the differentiation of hepatic mass lesions except liver cyst. In primary liver cancer hepatic lesions were mostly single (89.7%) and specific patterns of CT images (Type III or IV by Moriyama's classification) were present, while in metastatic liver cancer hepatic lesions were multiple (75.9%) and type I or II was predominant. The majority of lesions (66.7%) were equally visualized before and after contrast enhancement (C.E.) in metastatic liver cancer, while they were better defined following C.E. in 81.2% in primary liver cancer.

    Between 1 January 2010 and 31 December 2016, a total of 14 U.S. and international military personnel in training at Joint Base San Antonio-Lackland, TX, were hospitalized due to suspected pulmonary tuberculosis (TB); of these, five personnel were diagnosed with active TB disease. Only one TB case had pulmonary symptoms, but these symptoms were not suggestive of TB. The incidence rate in the training population was 1.89 per 100,000 population (95% CI: 0.81, 4.42), with a higher rate when restricted to international military students attending the Defense Language Institute English Language Center. No instances of TB transmission were identified. The variety of atypical presentations and their resulting diagnostic and public health challenges prompted this retrospective review of all hospitalized cases. This case series highlights both the importance of a high index of clinical suspicion when TB is being considered in close congregate settings as well as the risk of overreliance on acid-fast bacilli staining and nucleic acid amplification testing for ruling out active pulmonary disease in young, otherwise healthy trainees. Practical solutions are suggested.

  12. Nonalcoholic fatty liver disease: molecular mechanisms for the hepatic steatosis.

    Liver plays a central role in the biogenesis of major metabolites including glucose, fatty acids, and cholesterol. Increased incidence of obesity in the modern society promotes insulin resistance in the peripheral tissues in humans, and could cause severe metabolic disorders by inducing accumulation of lipid in the liver, resulting in the progression of non-alcoholic fatty liver disease (NAFLD). NAFLD, which is characterized by increased fat depots in the liver, could precede more severe diseases such as non-alcoholic steatohepatitis (NASH), cirrhosis, and in some cases hepatocellular carcinoma. Accumulation of lipid in the liver can be traced by increased uptake of free fatty acids into the liver, impaired fatty acid beta oxidation, or the increased incidence of de novo lipogenesis. In this review, I would like to focus on the roles of individual pathways that contribute to the hepatic steatosis as a precursor for the NAFLD.

    Schistomiasis mansoni infection is a leading cause of severe morbidity in the Sudan. Most of the morbidity and mortality are due to the development of hepatic periportal fibrosis and consequent portal hypertension and bleeding varices. This is a hospital-based, retro-prospective study in the period from 1980-1995. Liver disease (i.e. periportal fibrosis) and its clinical presentation were studied in relation to the degree of fibrosis and other pathological, haematological, and biochemical parameters. The study identified the common hospital presenting symptoms, assessed factors that influence pathogenesis of periportal fibrosis and its severity, as well as, defined criteria which predict those patients who are at risk of bleeding. 898 patients were included. The common presenting symptoms were left hypochondrial pain, haematemesis and enlarged spleen (Towal). Males were found to have an increase prevalence of periportal fibrosis. Splenomegaly was found in almost all patients of the study of different age groups, but spleen size didn't show any significant difference between bleeders and non-bleeders (p=0.28). A sharp rise in the prevalence of bleeding was noted after the age of 16 years. Upper gastrointestinal bleeding was found to be more common

    Technetium-99m N-pyridoxyl-5-methyltryptophan (PMT) cholescintigraphy has been performed in 46 consecutive patients with diffuse liver parenchymal diseases, including acute hepatitis (9), chronic hepatitis (17), and liver cirrhosis (20), and 18 controls. Blood clearance rate, liver uptake rate, liver excretion rate, and half time (T1/2) were determined from cardiac and hepatic time-activity curves. Regarding the four parameters, there were statistically significant differences between the control group and the groups of acute hepatitis and liver cirrhosis. Both blood clearance rate and liver uptake rate were well correlated with ICG-k values (r = 0.874 and r = 0.791, respectively). Liver excretion rate was most highly correlated with total serum bilirubin levels (r = 0.763), followed by ICG-k values. T1/2 was well correlated as well with total serum bilirubin levels. During the process where liver excretory ability was lowered in association with elevated serum bilirubin levels, threshold values for liver excretion rate appeared to be established. Cholescintigraphy may be of value in evaluating the pathophysiology of diffuse liver parenchymal diseases in that it is capable of quantitatively determining excretory function of hepatic cells.

  16. Periodontal disease and liver cirrhosis: A systematic review

    Science.gov (United States)

    2015-01-01

    Objectives: Studies suggest that periodontal disease, a source of subclinical and persistent infection, may be associated with various systemic conditions, including liver cirrhosis. The aim of this study was to examine the literature and determine the relationship between periodontal disease and liver cirrhosis and to identify opportunities and directions for future research in this area. Methods: A systematic review of English articles in the PubMed, EMBASE, and Scopus databases was conducted using search terms including ‘liver cirrhosis’, ‘end-stage liver disease’, ‘liver diseases’, ‘oral health’, ‘periodontal disease’, ‘mouth disease’, ‘gingivitis’, and ‘periodontitis’. Results: Thirteen studies published between 1981 and 2014 were found to include data on oral health and periodontal disease in cirrhotic patients. Studies indicated an increased incidence of periodontal disease in patients with liver cirrhosis, measured with several different periodontal indices. The reported prevalence of periodontal disease in cirrhosis patients ranged from 25.0% to 68.75% in four studies and apical periodontitis was found in 49%–79% of the patients. One study found that mortality was lower among patients who underwent dental treatment versus non-treated patients. Another study suggested an association between periodontal disease and the progression of liver cirrhosis, but data are sparse and conflicting as to whether periodontal disease is correlated to cirrhosis aetiology and severity. Conclusion: Despite the clinical reality of periodontal disease in liver cirrhosis patients, there are few published studies. Before clinical implications can be addressed, more data on the prevalence of and correlation between periodontal disease and liver cirrhosis aetiology, duration, and progression are needed.

    Liver disease is associated with both hemorrhagic and thrombotic processes, including an elevated risk of intracranial hemorrhage. We sought to assess the relationship between liver disease and outcomes after stroke, as measured by discharge disposition. Using administrative claims data, we identified a cohort of patients hospitalized with stroke in California, Florida, and New York from 2005 to 2013. The predictor variable was liver disease. All diagnoses were defined using validated diagnosis codes. Ordinal logistic regression was used to analyze the association between liver disease and worsening discharge disposition: home, nursing/rehabilitation facility, or death. Secondarily, multiple logistic regression was used to analyze the association between liver disease and in-hospital mortality. Models were adjusted for demographics, vascular risk factors, and comorbidities. We identified 121 428 patients with intracerebral hemorrhage and 703 918 with ischemic stroke. Liver disease was documented in 13 584 patients (1.7%). Liver disease was associated with worse discharge disposition after both intracerebral hemorrhage (global odds ratio, 1.28; 95% confidence interval, 1.19-1.38) and ischemic stroke (odds ratio, 1.23; 95% confidence interval, 1.17-1.29). Similarly, liver disease was associated with in-hospital death after both intracerebral hemorrhage (odds ratio, 1.33; 95% confidence interval, 1.23-1.44) and ischemic stroke (odds ratio, 1.60; 95% confidence interval, 1.51-1.71). Liver disease was associated with worse hospital discharge disposition and in-hospital mortality after stroke, suggesting worse functional outcomes. © 2016 American Heart Association, Inc.

    Full Text Available Background/Aims: Although the role of capsule endoscopy (CE in Crohn's disease (CD has expanded, CE is not used routinely for diagnosing and evaluating CD in Korea. We aimed to investigate current patterns of practice and evaluate the clinical significance of the use of CE in CD in Korean patients.Methods: Among 651 CE procedures performed for various indications, we retrospectively analyzed the medical records of patients who underwent CE in 57 cases of suspected CD (sCD and 14 cases of established CD (eCD.Results: In the sCD group, CE was most commonly used for the initial diagnosis of CD (54.4%. Capsule retention was found in only 1 patient in the eCD group (1/71, 1.4%. In the sCD group, 28.1% of patients were diagnosed with CD on the basis of CE findings; other diseases diagnosed included tuberculous enteritis (7.0%, non-steroidal anti-inflammatory drug-induced enteropathy (5.3%, and other enteritis (17.5%. Only 11.5% of patients with eCD (14/122 underwent CE. The indication for CE in the 14 patients with eCD was to assess disease extent and activity. The overall diagnostic yield of CE was 59.7%. Therapeutic strategies were changed in 70.2% of patients in the sCD group and 50% of those in the eCD group based on CE findings.Conclusions: In clinical practice, CE was most commonly indicated for the initial diagnosis of CD and was not generally performed in patients with eCD. CE appears to be an effective diagnostic modality for evaluating sCD and is useful for determining therapeutic strategies for patients with sCD and those with eCD.

    Coffee is one of the most commonly consumed beverages in the world. Consequently, it is important to consider the impact of coffee on health and disease. A daily intake of at least three cups of coffee is likely to have beneficial health effects, especially in patients at risk of liver diseases. Coffee has been associated with decreased liver inflammation, prevention of cirrhosis, reduced steatosis and lower incidence of hepatocellular carcinoma. It is not yet possible to make clear recommendations, but coffee can likely be included as part of a healthy diet for patients with liver diseases.

    Laparoscopic surgical procedures are increasing in scope and in variety. The benefits of decreased wound morbidity and pain have been well documented for multiple procedures that have traditionally required laparotomy. Although there are few controlled studies to document them, these benefits may be evident from simple clinical observation. Cystic disease of the liver is a condition that is treated largely for symptomatic reasons. The so-called noninvasive or radiographic guided methods of treatment for cystic disease of the liver are fraught with high recurrence rates. We present four cases of cystic disease of the liver treated laparoscopically, followed with pertinent discussion.

    Infiltrating monocytes have been demonstrated to contribute to tissue damage in experimental models of liver injury and fibrosis. However, less is known about monocyte infiltration in the livers of patients with chronic liver diseases (CLD). In the present study, we demonstrated that CD68+ hepatic macrophages and MAC387+ infiltrating monocytes were significantly increased in the livers of CLD patients with different etiologies as compared with normal liver tissue. In addition, CLD patients with higher inflammatory grading scores had more CD68+ macrophages and MAC387+ monocytes infiltration in their livers compared to those with lower scores. Significantly more MAC387+ infiltrating monocytes were found in the liver tissue of CLD patients with higher fibrotic staging scores compared to those with lower scores. Monocyte chemoattractant protein-1 (MCP-1) expression was significantly increased in the livers of CLD patients with different etiologies. MCP-1 staining scores were significantly positively associated with the numbers of MAC387+ infiltrating monocytes in CLD patients. Taken together, our results demonstrate that infiltrating monocytes may play a pathological role in exacerbating chronic liver inflammation and fibrosis in CLD. MCP-1 may be involved in the monocyte infiltration and progression of liver inflammation and fibrosis in CLD.

    The aim of our study is to evaluate if in children with highly positive serology and HLA-DQ2/DQ8 (triple test, TT) and only extra-intestinal symptoms, it is possible to omit performing an intestinal biopsy for celiac disease (CD) diagnosis, as suggested by the new European Society for Pediatric Gastroenterology, Hepatology and Nutrition ESPGHAN guidelines. In this retrospective study a total of 105 patients, suspected of having CD because of extra-intestinal symptoms and showing serum tissue transglutaminase antibody (anti-tTG) and anti-endomysial antibody (EMA) measurements and HLA genotyping, were considered for the final analysis (33 boys and 72 girls; age range 1.5-17.6 years). Histological findings confirmed diagnosis of CD in 97 (92.4%) patients. Forty-one patients (39%) showed anti-tTG >10 times normal values, positive EMA and positive HLA-DQ2/DQ8 (positive TT). All of them had a diagnosis of CD, therefore there were no false positive cases. Sixty-four patients were negative for the TT. In eight cases, CD was ruled out and these were considered true negative cases. In the remaining 56 negative TT patients, intestinal biopsy confirmed CD diagnosis and they were considered false negatives. Based on these results, specificity for the TT was 100% and sensitivity was 42.3%. On the basis of the present study, diagnosis of CD can be reliably performed without a duodenal biopsy in children with only extra-intestinal symptoms.

    The contrast enema (CE) is commonly utilized for suspected Hirschsprung disease (HD) patients. We set out to determine the utility of the CE in the newborn for clinically suspicious HD. All CEs performed for suspicion of HD in neonates from January 2004 to December 2013 were reviewed by two pediatric radiologists who were blinded to the original interpretations and final diagnoses. A standardized scoring sheet was utilized to document essential radiographic findings. Definitive diagnoses were determined by pathology. Descriptive statistics, likelihood ratios, and interrater agreement were determined. 158 CEs were reviewed. Interrater agreement was 89% with kappa (95% CI) of 0.63 (0.47-0.76). Common indications for CE were similar between non-HD and HD groups. The positive, inconclusive, and negative likelihood ratios (95% CI) were 38 (10-172), 3.2 (1.3-9.1), and 0.15 (0.06-0.47), respectively, leading to posttest probabilities for positive, inconclusive, and negative tests of 83%, 32%, and 2.5%, respectively. Although radiographic positive CE for HD portends a high probability of HD, inconclusive studies still represent a significant increased risk. In clinically suspicious infants for HD, those with inconclusive studies may benefit from a lower threshold to perform follow-up rectal biopsy. Copyright © 2015 Elsevier Inc. All rights reserved.

  8. Myocardial imaging in the noninvasive evaluation of patients with suspected ischemic heart disease

    Three noninvasive radioactive tracer techniques for evaluating patients with ischemic heart disease are described: (1) myocardial perfusion imaging, (2) acute infarct imaging, and (3) the gated blood pool scan. Myocardial perfusion imaging with tracers that distribute in the myocardium in relation to regional blood flow allows detection of patients with transmural and nontransmural infarction by the finding of decreased tracer concentration in the affected region of the myocardium. If these tracers are injected at the time of maximal stress to patients with significant coronary arterial stenosis but without infarction, areas of transient ischemia can be identified as zones of decreased tracer concentration not found when an examination is performed at rest. Acute infarct imaging with tracers that localize in acutely damaged tissue permits separation of patients with acute myocardial necrosis from those without infarction and those with more chronic damage. The gated blood pool scan permits assessment of left ventricular function and regional wall motion. The measurement of ventricular volumes, ejection fraction and regional wall motion adds significantly to the determination of hemodynamic variables in assessing patients with acute infarction. The technique also permits detection of right ventricular dysfunction. Performance of a combination of these radioactive tracer techniques is often advantageous, particularly in patients with suspected infarction. The techniques can establish whether infarction is present, whether it is acute, where the damage is located and how extensive it is; they can also provide a measure of the effect of this damage on left ventricular function

    Nonalcoholic fatty liver diseases (NAFLD) is one of the most common chronic liver disease in Western countries. Oxygen is a central component of the cellular microenvironment, which participate in the regulation of cell survival, differentiation, functions and energy metabolism. Accordingly, sufficient oxygen supply is an important factor for tissue durability, mainly in highly metabolic tissues, such as the liver. Accumulating evidence from the past few decades provides strong support for the existence of interruptions in oxygen availability in fatty livers. This outcome may be the consequence of both, impaired systemic microcirculation and cellular membrane modifications which occur under steatotic conditions. This review summarizes current knowledge regarding the main factors which can affect oxygen supply in fatty liver. Copyright © 2017 The Authors. Published by Elsevier B.V. All rights reserved.

    Purpose: To determine the value of 18 F-fluoro-2-deoxy-D-glucose (FDG) positron emission tomography (PET)/computed tomography (CT) for diagnosing renal or hepatic cyst infection in patients with autosomal dominant polycystic kidney disease (ADPKD). Methods: This retrospective single-center study included all patients with ADPKD who underwent FDG-PET/CT because of suspected cyst infection between 2010 and 2017. Results: Thirty FDG-PET/CT scans of thirty individual patients were included, of which 19 were positive for cyst infection. According to a previously established clinical and biochemical reference standard, FDG-PET/CT achieved sensitivity of 88.9%, specificity of 75.0%, positive predictive value of 84.2%, and negative predictive value of 81.8% for the diagnosis of cyst infection. In 5 cases, FDG-PET/CT suggested a different pathologic process that explained the symptoms, including pneumonia ( n = 1), generalized peritonitis ( n = 1), pancreatitis ( n = 1), colitis ( n = 1), and cholangitis ( n = 1). Total duration of hospital stay and duration between FDG-PET/CT scan and hospital discharge of patients with an FDG-PET/CT scan positive for cyst infection were significantly longer than those with a negative scan ( P = 0.005 and P = 0.009, respectively). Creatinine levels were significantly higher in patients with an FDG-PET/CT scan positive for cyst infection than in patients with a negative scan ( P = 0.015). Other comparisons of clinical parameters (age, gender, presence of fever (>38.5°C) for more than 3 days, abdominal pain, history of solid organ transplantation and nephrectomy, immune status), laboratory values (C-reactive protein level (CRP), leukocyte count, estimated glomerular filtration rate), and microbiologic results (blood and urine cultures) were not significantly different ( P = 0.13-1.00) between FDG-PET/CT-positive and -negative patients. Conclusion: FDG-PET/CT is a useful and recommendable (upfront) imaging modality for the evaluation of

    Full Text Available Liver failure has a high fatality rate and greatly threatens human health. Liver transplantation can effectively reduce the fatality rate. However, the problems such as donor shortage and allograft rejection limit the wide application of liver transplantation. An accurate early assessment helps to evaluate patients′ condition and optimize therapeutic strategies. At present, commonly used systems for prognostic evaluation include the King′s College Hospital, MELD, integrated MELD, Child-Pugh score, CLIF-SOFA, CLIF-C ACLFS, and D-MELD, and each system has its own advantages and disadvantages. Among these systems, the MELD scoring system is the most commonly used one, and the D-MELD scoring system is the most innovative one, which can be used for patients on the waiting list for liver transplantation. This article elaborates on the characteristics and predictive value of each scoring system in clinical practice.

    Full Text Available Alcoholism is one of the leading diseases affecting people’s health and immunity worldwide. Nearly 30 thousand people in the USA die from chronic liver damage. The liver is the central organ in the metabolism of alcohol. Alcohol is primarily a hepatotoxic agent. Hepatotoxicity of alcohol is clinically manifested by the development of alcoholic fatty liver, alcoholic hepatitis and alcoholic cirrhosis. It is characterized by appropriate symptomatology, depending on the degree of liver damage. Excessive use of alcohol for a long period of time, along with malnutrition, genetic and ethnic predisposition, leads to alcoholic cirrhosis and the development of its complications. Portal hypertension damages other organs and organ systems, causing hepatopulmonary syndrome, hepatorenal syndrome, hepatic encephalopathy, spontaneous bacterial peritonitis, etc. For these reasons, alcoholism reduction is given priority, as well as reduction of morbidity and mortality of people with alcoholic chronic liver damage. Therefore, early diagnosis of alcohol abuse is necessary, as well as timely diagnosis of different degrees of alcoholic liver damage. The diagnosis of chronic alcoholic liver damage is set on the basis of confirmed data of alcohol consumption; liver function test (serum markers aminotransferase, gammaglutamyl transferase, prothrombin time, serum bilirubin and albumin level; serum markers of liver fibrosis. Fibrosis markers are directly involved in sedimentation and dissolution of extracellular matrix, i.e. in the process of fibrogenesis and fibrinolysis of liver tissues. They include markers and enzymes of metabolism, as well as cytokines and chemokines.

    Non-alcoholic fatty liver disease (NAFLD), encompassing both simple steatosis and non-alcoholic steato-hepatitis (NASH), is the most common cause of liver disease in Australia. Non-alcoholic fatty liver disease needs to be considered in the context of the metabolic syndrome, as cardiovascular disease will account for much of the mortality associated with NAFLD. To provide an approach to the identification of NAFLD in general practice, the distinction between simple steatosis and NASH, and the management of these two conditions. Non-alcoholic steato-hepatitis is more common in the presence of diabetes, obesity, older age and increased inflammation, and is more likely to progress to cirrhosis. Cirrhosis may be complicated by hepatocellular carcinoma or liver failure. Hepatocellular carcinoma has also been described in NASH without cirrhosis. Assessment and treatment of features of the metabolic syndrome may reduce associated cardiovascular mortality. Numerous agents have been evaluated, but weight loss remains the only effective treatment for NAFLD.

    Full Text Available Nonalcoholic fatty liver disease (NAFLD has been developing rapidly in recent years and has become one of the most common liver diseases. However, its pathogenesis remains unclear, and there are no widely accepted therapeutic regimens. NAFLD has a complex pathogenesis with multiple factors involved, including insulin resistance, oxidative stress, bile acid metabolic disorders, and autophagy. This article reviews the pathogenesis of NAFLD in order to provide a reference for further research and clinical treatment in the future.

    Full Text Available Obstructive sleep apnea (OSA is recurrent obstruction of the upper airway during sleep leading to intermittent hypoxia (IH. OSA has been associated with all components of the metabolic syndrome as well as with non-alcoholic fatty liver disease (NAFLD. NAFLD is a common condition ranging in severity from uncomplicated hepatic steatosis to steatohepatitis (NASH, liver fibrosis and cirrhosis. The gold standard for the diagnosis and staging of NAFLD is liver biopsy. Obesity and insulin resistance lead to liver steatosis, but the causes of the progression to NASH are not known. Emerging evidence suggests that OSA may play a role in the progression of hepatic steatosis and the development of NASH. Several cross-sectional studies showed that the severity of IH in patients with OSA predicted the severity of NAFLD on liver biopsy. However, neither prospective nor interventional studies with continuous positive airway pressure (CPAP treatment have been performed. Studies in a mouse model showed that IH causes triglyceride accumulation in the liver and liver injury as well as hepatic inflammation. The mouse model provided insight in the pathogenesis of liver injury showing that (1 IH accelerates the progression of hepatic steatosis by inducing adipose tissue lipolysis and increasing free fatty acids (FFA flux into the liver; (2 IH up-regulates lipid biosynthetic pathways in the liver; (3 IH induces oxidative stress in the liver; (4 IH up-regulates hypoxia inducible factor 1 alpha and possibly HIF-2 alpha, which may increase hepatic steatosis and induce liver inflammation and fibrosis. However, the role of FFA and different transcription factors in the pathogenesis of IH-induced NAFLD is yet to be established. Thus, multiple lines of evidence suggest that IH of OSA may contribute to the progression of NAFLD but definitive clinical studies and experiments in the mouse model have yet to be done.

  19. The Interleukin-20 Cytokine Family in Liver Disease

    Full Text Available The three main causes of inflammation and chronic injury in the liver are viral hepatitis, alcohol consumption, and non-alcoholic steatohepatitis, all of which can lead to liver fibrosis, cirrhosis, and hepatocellular carcinoma, which in turn may prompt the need for liver transplant. The interleukin (IL-20 is a subfamily part of the IL-10 family of cytokines that helps the liver respond to damage and disease, they participate in the control of tissue homeostasis, and in the immunological responses developed in this organ. The best-studied member of the family in inflammatory balance of the liver is the IL-22 cytokine, which on the one hand may have a protective role in fibrosis progression but on the other may induce liver tissue susceptibility in hepatocellular carcinoma development. Other members of the family might also carry out this dual function, as some of them share IL receptor subunits and signal through common intracellular pathways. Investigators are starting to consider the potential for targeting IL-20 subfamily members in liver disease. The recently explored role of miRNA in the transcriptional regulation of IL-22 and IL-24 opens the door to promising new approaches for controlling the local immune response and limiting organ injury. The IL-20RA cytokine receptor has also been classified as being under miRNA control in non-alcoholic steatohepatitis. Moreover, researchers have proposed combining anti-inflammatory drugs with IL-22 as a hepatoprotective IL for alcoholic liver disease (ALD treatment, and clinical trials of ILs for managing severe alcoholic-derived liver degeneration are ongoing. In this review, we focus on exploring the role of the IL-20 subfamily of cytokines in viral hepatitis, ALD, non-alcoholic steatohepatitis, and hepatocellular carcinoma, as well as delineating the main strategies explored so far in terms of therapeutic possibilities of the IL-20 subfamily of cytokines in liver disease.

    Full Text Available Inborn errors of metabolism, which affect the liver are a large, continuously increasing group of diseases. Their clinical onset can occur at any age, from intrauterine period presenting as liver failure already at birth to late adulthood. Inherited metabolic disorders must be considered in differential diagnosis of every unexplained liver disease. Specific diagnostic work-up for either their confirmation or exclusion should start immediately since any postponing can result in delayed diagnosis and death or irreversible disability. This can be particularly painful while many inherited metabolic liver diseases are relatively easily treatable if diagnosed on time, for instance galactosemia or hereditary fructose intolerance by simple dietary means. Any unexplained liver disease, even one looking initially benign, should be considered as a potential liver failure and therefore should deserve proper attention. Diagnosis in neonates is additionally complicated because of the factors which can mask liver disease, such as physiological neonatal jaundice, normally relatively enlarged liver and increased transaminases at that age. In everyday practice, in order to reveal the etiology, it is useful to classify and distinguish some clinical patterns which, together with a few routine, widely available laboratory tests (aminotransferases, prothrombine time, albumin, gammaGT, total and conjugated bilirubin, ammonia, alkaline phosphatase and glucose make the search for the cause much easier. These patterns are isolated hyperbilirubinemia, syndrome of cholestasis in early infancy, hepatocellular jaundice, Reye syndrome, portal cirrhosis and isolated hepatomegaly. Despite the fact that some diseases can present with more than one pattern (for instance, alpha-1-antitrypsin deficiency as infantile cholestasis, but also as hepatocellular jaundice, and that in some disesases one pattern can evolve into another (for instance, Wilson disease from hepatocellular

    Objective: To describe the mortality pattern pertaining to chronic liver disease (CLD) in Northern Pakistan. Results: There were a total of 8529 admissions in twelve months period from August 2001 to July 2002. There were 283 (3.31%) total deaths. Out of these, 160 deaths were pertaining to medical causes. Out of these medical cases, 33 (20.6%) patients had died of chronic liver disease. Other major causes of death were cerebro-vascular accident (18.7%), malignancy (18.1%) and acute myocardial infarction (10.6%). Out of 33 patients of CLD, 12 (36%) presented with acute gastrointestinal (Gl) bleeding, 9(27%) presented with Ascites and 6(18%) presented with altered mental status due to hepatic encephalopathy. Rest of them had jaundice and fever as their initial presentation. Out of these 33 patients with CLD, 23 (70%) had hepatitis C virus (HCV) as cause of their liver disease, 4 (12%) had hepatitis B virus (HBV) infection, 3(9%) had both hepatitis B and hepatitis C virus infections and 3 (9%) had no known cause of their chronic liver disease. Conclusion: Chronic liver disease is a major cause of mortality in this part of Pakistan at a tertiary care hospital. HCV infection is the main cause of chronic liver disease followed by either HBV or a combination of these viruses. Major manifestations of CLD have been gastrointestinal bleeding, hepatic failure and portal hypertension.(author)

    2011-01-01

    Background: Chronicity of liver disease is determined either by duration of liver disease or by evidence of either severe liver disease or physical stigmata of chronic liver disease. Chronic liver disease may be caused commonly by persistent viral infections, metabolic diseases, drugs, autoimmune hepatitis, or unknown factors. The objective of this study was to find out the aetiology of chronic liver disease (CLD) in children. Methodology: It was a descriptive, prospective study which used a structured proforma designed to collect data of cases of CLD from both indoor and outdoor Paediatrics units of Fauji Foundation Hospital, Rawalpindi, and Children Hospital, Pakistan Institute of Medical Sciences, Islamabad. All children under 12 years having either clinical or biochemical evidence of liver disease and/or elevated liver enzymes for more than 3 months were included in this study. Results: Sixty cases of CLD were enrolled from indoor and outdoor units from January 2010 to July 201. Thirty nine (65%) cases were male and 21 (35%) were female. Eleven children were less than 1 year, 18 were 1-5 years old and 31 were 5-12 years of age. Viral hepatitis was the most common cause found in 22 (36.7%) cases. Out of these 22 patients with viral aetiology 19 (31.66%) patients had Hepatitis C and 3 (5%) had Hepatitis B. Glycogen storage disease was seen in 8.3% cases, and biliary atresia and Wilson disease in 6.7% each. Other less commonly found cases were autoimmune hepatitis, TORCH infections, hepatoma and drug induced hepatitis (1.7% each). Cause couldn't be established in 35% cases which remained idiopathic. Conclusion: Viral hepatitis is the leading cause of chronic liver disease in children, with the highest incidence of chronic Hepatitis C followed by metabolic disorders (glycogen storage disease and Wilson disease) and biliary atresia. Chronic viral hepatitis was most prevalent between 11 months to 12 years of age. Wilson disease was common in 3-7 years age group, and

    There have been reports of patients with antibodies to neuronal antigens misdiagnosed as sporadic Creutzfeldt-Jakob disease (sCJD). Conversely, low levels of antibodies to neuronal proteins have been reported in patients with sCJD. However, the frequency of misdiagnoses, or of antibodies in patients with subsequently confirmed sCJD, is not clear. We reviewed 256 consecutive cases of sCJD seen in the National Prion Clinic, of whom 150 had sera previously referred for selected antibody tests. Eighty-two available samples were retested for antibodies to N-methyl-d-aspartate receptor (NMDAR), the glycine receptor (GlyR), voltage-gated potassium channel (VGKC)-complex and the associated proteins, leucine-rich glioma inactivated 1 (LGI1) and contactin-associated protein 2 (CASPR2). Four of the initial 150 sera referred were positive; two had antibodies to NMDAR, and two to the VGKC-complex, one of which was also positive for GlyR antibodies. Of the 82 sCJD sera retested, one had VGKC-complex antibodies confirming the previous result, two had CASPR2 and GlyR antibodies and one had CASPR2 and NMDAR antibodies; all antibodies were at low levels. Over the same period three patients with autoimmune encephalitis and high VGKC-complex antibodies were initially referred as sCJD. This study indicates that VGKC-complex/LGI1 antibodies. Low titres of neuronal antibodies occur only rarely in suspected patients with sCJD and when present should be interpreted with caution. Published by the BMJ Publishing Group Limited.

    To evaluate hepatobiliary magnetic resonance imaging (MRI) using Gd-EOB-DTPA in relation to various liver function tests in patients with liver disorders. Fifty-one patients with liver disease underwent Gd-EOB-DTPA-enhanced liver MRI. Based on region-of-interest (ROI) analysis, liver signal intensity was calculated using the spleen as reference tissue. Liver-spleen contrast ratio (LSCR) and relative liver enhancement (RLE) were calculated. Serum levels of total bilirubin, gamma glutamyl transpeptidase (GGT), aspartate aminotransferase (AST), alanine aminotransferase (ALT), glutamate dehydrogenase (GLDH), lactate dehydrogenase (LDH), serum albumin level (AL), prothrombin time (PT), creatinine (CR) as well as international normalised ratio (INR) and model for end-stage liver disease (MELD) score were tested for correlation with LSCR and RLE. Pre-contrast LSCR values correlated with total bilirubin (r = -0.39; p = 0.005), GGT (r = -0.37; p = 0.009), AST (r = -0.38; p = 0.013), ALT (r = -0.29; p = 0.046), PT (r = 0.52; p < 0.001), GLDH (r = -0.55; p = 0.044), INR (r = -0.42; p = 0.003), and MELD Score (r = -0.53; p < 0.001). After administration of Gd-EOB-DTPA bilirubin (r = -0.45; p = 0.001), GGT (r = -0.40; p = 0.004), PT (r = 0.54; p < 0.001), AST (r = -0.46; p = 0.002), ALT (r = -0.31; p = 0.030), INR (r = -0.45; p = 0.001) and MELD Score (r = -0.56; p < 0.001) significantly correlated with LSCR. RLE correlated with bilirubin (r = -0.40; p = 0.004), AST (r = -0.38; p = 0.013), PT (r = 0.42; p = 0.003), GGT (r = -0.33; p = 0.020), INR (r = -0.36; p = 0.011) and MELD Score (r = -0.43; p = 0.003). Liver-spleen contrast ratio and relative liver enhancement using Gd-EOB-DTPA correlate with a number of routinely used biochemical liver function tests, suggesting that hepatobiliary MRI may serve as a valuable biomarker for liver function. The strongest correlation with liver enhancement was found for the MELD Score. (orig.)

    The main aim of the study is to study the clinical profile of disorders of the liver and hepatobiliary system in paediatric patients and to correlate the histopathology findings of liver biopsy in chronic liver disease. Another aim being to assess the prognosis and to know the outcome and the effects of treatment in chronic liver diseases in paediatric age group. It was a prospective study, included the clinical profile of Chronic Liver Diseases (CLD) in children and the histopathological correlation. A total of 55 children were thoroughly investigated by doing relevant investigations and liver biopsy. A male predominance (60%) was noted with maximum incidence in the age group of 6-12 years. The incidence of CLD was 1.1% of total admissions. The most common presenting complaint was jaundice and abdominal distension. Hepatic encephalopathy was noted in 29% patients. Hepatomegaly was seen in 63% patients and spleenomegaly was seen in 60% patients. The incidence of cirrhosis on liver biopsy was 42% (23cases) in CLD patients. The most common diagnosis on histopathology was Wilson's disease (22%), followed by hepatitis and autoimmune hepatitis. The predominant spectrum of CLD was metabolic liver disease and also the predominant cause of death. As the incidence of CLD is quite low, a very high index of suspicion is required for its diagnosis. Some uncommon causes of CLD in children were seen in our study like neutral lipid storage disease, α1-Antitrypsin deficiency disease, lupus hepatitis, Alagille syndrome and Budd-Chiari syndrome. A patient of CLD with jaundice and hepatomegaly should be treated aggressively as those are the poor prognostic indicators of the disease. Hepatic encephalopathy and cirrhosis are also associated with poor outcome in patients with CLD. Liver biopsy histopathology by an expert and its correlation with laboratory investigations plays an important role in the diagnosis of CLD. The major cause of deaths in patients with CLD is due to end stage

    Many children with chronic liver disease require a liver transplant. These patients are prone to various infections, including Epstein-Barr virus infection. This study sought to measure the Epstein-Barr viral load by polymerase chain reaction before a liver transplant. This cross-sectional study was done at the Shiraz University of Medical Sciences, Shiraz, Iran, in 2011. All patients were aged younger than 18 years with chronic liver disease and were candidates for a liver transplant at the Shiraz Nemazee Hospital Organ Transplant Center. They had been investigated regarding their demographic characteristics, underlying disease, laboratory findings, and Epstein-Barr viral load by real-time TaqMan polymerase chain reaction. Ninety-eight patients were studied and the mean age was 6.5 ± 5.9 years. Cryptogenic cirrhosis was the most-prevalent reason for liver transplant, and the death rate before a transplant was 15%. Among the study subjects, 6 had measurable Epstein-Barr viral load by polymerase chain reaction before the transplant, and 4 of them had considerably higher Epstein-Barr viral loads (more than 1000 copies/mL). With respect to the close prevalence of posttransplant lymphoproliferative disease (6%) and the high Epstein-Barr viral load in the patients before a transplant (4%), high pretransplant Epstein-Barr viral load can be considered a risk factor for posttransplant lymphoproliferative disorder.

    Full Text Available In recent years, the incidence of nonalcoholic fatty liver disease (NAFLD has increased gradually along with the rising prevalence of obesity, type 2 diabetes, and hyperlipidemia, and NAFLD has become one of the most common chronic liver diseases in the world and the second major liver disease after chronic viral hepatitis in China. However, its pathogenesis has not yet been clarified. Animal models are playing an important role in researches on NAFLD due to the facts that the development and progression of NAFLD require a long period of time, and ethical limitations exist in conducting drug trials in patients or collecting liver tissues from patients. The animal models with histopathology similar to that of NAFLD patients are reviewed, and their modeling principle, as well as the advantages and disadvantages, are compared. Animal models provide a powerful tool for further studies of NAFLD pathogenesis and drug screening for prevention and treatment of NAFLD.

    The need for a suitable parameter to evaluate patients with chronic liver disease has been felt for some time, especially in order to judge the response to surgical shunts and the influence of certain drugs and diets on the liver. Since the liver is a major organ for carbohydrate metabolism, it was decided to analyze the in vivo oxidation of such substrates as glucose and galactose labeled with 14 C. Moderately advanced ''Indian childhood cirrhosis'' and idiopathic fatty hepatic infiltration were selected to represent diffuse chronic liver disease. Oral administration of 14 C-U-glucose or 14 C-1-galactose was followed by analyses of 14 CO 2 in breath by liquid scintillation counting. Conversion of 14 C-glucose to 14 CO 2 was accelerated by both diseases. On the other hand, oxidation of 14 C-galactose was slowed in fatty infiltration and was markedly subnormal in Indian childhood cirrhosis

    Patients with liver disease are at increased risks of both thrombotic and bleeding complications. Many have atrial fibrillation (AF) or venous thromboembolism (VTE) necessitating oral anticoagulant agents (OACs). Recent evidence has contradicted the assumption that patients with liver disease are "auto-anticoagulated" and thus protected from thrombotic events. Warfarin and non-vitamin K-antagonist OACs have been shown to reduce thrombotic events safely in patients with either AF or VTE. However, patients with liver disease have largely been excluded from trials of OACs. Because all currently approved OACs undergo metabolism in the liver, hepatic dysfunction may cause increased bleeding. Thus, the optimal anticoagulation strategy for patients with AF or VTE who have liver disease remains unclear. This review discusses pharmacokinetic and clinical studies evaluating the efficacy and safety of OACs in patients with liver disease and provides a practical, clinically oriented approach to the management of OAC therapy in this population.

    Military doctors should have a uniform position to the use of alcohol. Now alcohol is the basic pathogenic factor in development of a lethal cirrhosis of a liver. The most known sayings justifying the use of alcohol, are insolvent. Useful doses of alcohol does not exist. The quantity of used alcohol has the great value. Only at achievement of age 21 year it is possible to use safe doses of alcohol. A safe dose of pure alcohol (ethanol) less than 30,0 in day. In a basis of prophylaxis of a cirrhosis of a liver there is a medical educational activity.

    Evaluation of the liver for focal lesions is extremely important because the liver is one of the most common sites for metastatic disease. Most patients with metastatic deposits to the liver have a survival rate of about 6 months. Thus, metastatic disease to the liver has an extremely grave prognosis. In the past patients with hepatic lesions had no therapeutic recourse. However, with recent aggressive surgical advances (such as partial hepatectomies) and hepatic artery embolization, survival of patients with hepatic metastases has increased. Thus it is important for noninvasive imaging not only to detect lesions early in their course, but also to give their true hepatic involvement and the extent of the neoplastic process elsewhere in the body. Recent advances in imaging have been rapidly changing over the past 5 years. These changes have been more rapid in computed tomography (CT) and ultrasound than in radionuclide imaging. Thus, the question addressed in this chapter is: What is the relationship of hepatic ultrasound to the other current diagnostic modalities in detecting metastatic liver disease and other focal liver lesions? Also, what is its possible future relationship to nuclear magnetic resonance?

    AIM: Nonalcoholic steatohepatitis (NASH) is a severe form of nonalcoholic fatty liver disease (NAFLD), and progresses to the end stage of liver disease. Biochemical markers of liver fibrosis are strongly associated with the degree of histological liver fibrosis in patients with chronic liver disease.However, data are few on the usefulness of markers in NAFLD patients. The aim of this study was to identify better noninvasive predictors of hepatic fibrosis, with special focus on markers of liver fibrosis, type Ⅵ collagen 7S domain and hyaluronic acid.METHODS: One hundred and twelve patients with histologically proven NAFLD were studied.RESULTS: The histological stage of NAFLD correlated with several clinical and biochemical variables, the extent of hepatic fibrosis and the markers of liver fibrosis were relatively strong associated. The best cutoff values to detect NASH were assessed by using receiver operating characteristic analysis: type Ⅵ collagen 7S domain ≥5.0 ng/mL, hyaluronic acid ≥43 ng/mL. Both markers had a high positive predictive value: type Ⅵ collagen 7S domain, 86% and hyaluronic acid,92%. Diagnostic accuracies of these markers were evaluated to detect severe fibrosis. Both markers showed high negative predictive values: type Ⅵ collagen 7S domain (≥5.0 ng/mL),84% and hyaluronic acid (≥50 ng/mL), 78%, and were significantly and independently associated with the presence of NASH or severe fibrosis by logistic regression analysis.CONCLUSION: Both markers of liver fibrosis are useful in discriminating NASH from fatty liver alone or patients with severe fibrosis from patients with non-severe fibrosis.

  13. Immunology in the liver--from homeostasis to disease.

    The liver is a central immunological organ with a high exposure to circulating antigens and endotoxins from the gut microbiota, particularly enriched for innate immune cells (macrophages, innate lymphoid cells, mucosal-associated invariant T (MAIT) cells). In homeostasis, many mechanisms ensure suppression of immune responses, resulting in tolerance. Tolerance is also relevant for chronic persistence of hepatotropic viruses or allograft acceptance after liver transplantation. The liver can rapidly activate immunity in response to infections or tissue damage. Depending on the underlying liver disease, such as viral hepatitis, cholestasis or NASH, different triggers mediate immune-cell activation. Conserved mechanisms such as molecular danger patterns (alarmins), Toll-like receptor signalling or inflammasome activation initiate inflammatory responses in the liver. The inflammatory activation of hepatic stellate and Kupffer cells results in the chemokine-mediated infiltration of neutrophils, monocytes, natural killer (NK) and natural killer T (NKT) cells. The ultimate outcome of the intrahepatic immune response (for example, fibrosis or resolution) depends on the functional diversity of macrophages and dendritic cells, but also on the balance between pro-inflammatory and anti-inflammatory T-cell populations. As reviewed here, tremendous progress has helped to understand the fine-tuning of immune responses in the liver from homeostasis to disease, indicating promising targets for future therapies in acute and chronic liver diseases.

    Ultrasonography (US) and computed tomography (CT) were performed on respectively 67 and 42 (altogether 72) patients, for the assessment of intrahepatic cholestasis. The diagnostic ability to differentiate between malignant (17 patients) and benign (55 patients) liver disease was analyzed. Coarse echogenicity of the liver led to inconclusive results in differentiating between cirrhosis (2 out of 29 patients) and malignant infiltration (4 out of 15 patients) by US. Other benign liver diseases in 23 patients, including acute hepatitis, chronic active hepatitis, fatty liver, and liver congestion, were correctly interpreted as benign. CT correctly disclosed malignant liver disease in all cases. A false positive diagnosis of malignancy was encountered in 4 (out of 17) patients with decompensated hepatic cirrhosis because of non-homogeneous expansive areas on CT in 3 cases. The true cause was in 2 patients non-uniform fatty infiltration, and in one patient with acute hepatitis A, small hypodense lesions. Among cholestatic patients, decompensated cirrhosis and malignant liver infiltration could not always be differentiated on US or CT. (orig.)

    Full Text Available Metabolic syndrome that represents a totality of interrelated carbohydrate metabolism and lipid disorders, as well as a mechanism regulating arterial tension and endothelium function is one of the critical issues in pediatrics. In recent years, children with metabolic syndrome are increasingly diagnosed with liver injuries symptoms that are associated with a fatty transformation of the liver [1–3]. In this case, non-alcoholic fatty liver disease (NAFLD, a liver manifestation of metabolic syndrome is diagnosed. The diagnosis is confirmed in the absence of alcohol abuse in the past medical history, virus and autoimmune liver disease markers, elimination of toxic and drug influence, as wells as disorders of copper and iron exchange in the patient’s system. One of the key risk factors for developing NAFLD in children is overeating and reduced physical activities. It was believed in the past that NAFLD is relatively benign, however, there is evidence in current literature that this is a pathological condition that may develop and result in extreme fibrotic alterations in the liver parenchymatous tissue all the way to cirrhosis and hepatocellular carcinoma [4]. Early-stage identification and timely launch of therapy for NAFLD in children represents one of the most important objectives in modern healthcare. Key words: metabolic syndrome, non-alcoholic fatty liver disease, children, steatohepatosis. (Pediatric Pharmacology. – 2010; 7(6:68-72

    To investigate changes in hepatic and splenic stiffness in patients without chronic liver disease during liver resection for hepatic tumors. Patients scheduled for liver resection for hepatic tumors were considered for enrollment. Tissue stiffness measurements on liver and spleen were conducted before and two days after liver resection using point shear-wave elastography. Histological analysis of the resected liver specimen was conducted in all patients and patients with marked liver fibrosis were excluded from further study analysis. Patients were divided into groups depending on size of resection and whether they had received preoperative chemotherapy or not. The relation between tissue stiffness and postoperative biochemistry was investigated. Results are presented as median (interquartile range). 35 patients were included. The liver stiffness increased in patients undergoing a major resection from 1.41 (1.24-1.63) m/s to 2.20 (1.72-2.44) m/s ( P = 0.001). No change in liver stiffness in patients undergoing a minor resection was found [1.31 (1.15-1.52) m/s vs 1.37 (1.12-1.77) m/s, P = 0.438]. A major resection resulted in a 16% (7%-33%) increase in spleen stiffness, more ( P = 0.047) than after a minor resection [2 (-1-13) %]. Patients who underwent preoperative chemotherapy ( n = 20) did not differ from others in preoperative right liver lobe [1.31 (1.16-1.50) vs 1.38 (1.12-1.56) m/s, P = 0.569] or spleen [2.79 (2.33-3.11) vs 2.71 (2.37-2.86) m/s, P = 0.515] stiffness. Remnant liver stiffness on the second postoperative day did not show strong correlations with maximum postoperative increase in bilirubin ( R 2 = 0.154, Pearson's r = 0.392, P = 0.032) and international normalized ratio ( R 2 = 0.285, Pearson's r = 0.534, P = 0.003). Liver and spleen stiffness increase after a major liver resection for hepatic tumors in patients without chronic liver disease.

    Full Text Available Obesity with associated comorbidities is currently a worldwide epidemic and among the most challenging health conditions in the 21st century. A major metabolic consequence of obesity is insulin resistance which underlies the pathogenesis of the metabolic syndrome. Nonalcoholic fatty liver disease (NAFLD is the hepatic manifestation of obesity and metabolic syndrome. It comprises a disease spectrum ranging from simple steatosis (fatty liver, through nonalcoholic steatohepatitis (NASH to fibrosis, and ultimately liver cirrhosis. Abnormality in lipid and lipoprotein metabolism accompanied by chronic inflammation is the central pathway for the development of metabolic syndrome-related diseases, such as atherosclerosis, cardiovascular disease (CVD, and NAFLD. This paper focuses on pathogenic aspect of lipid and lipoprotein metabolism in NAFLD and the relevant mouse models of this complex multifactorial disease.

  19. Liver stiffness by transient elastography predicts liver-related complications and mortality in patients with chronic liver disease.

    Jack X Q Pang

    Full Text Available Liver stiffness measurement (LSM by transient elastography (TE, FibroScan is a validated method for noninvasively staging liver fibrosis. Most hepatic complications occur in patients with advanced fibrosis. Our objective was to determine the ability of LSM by TE to predict hepatic complications and mortality in a large cohort of patients with chronic liver disease.In consecutive adults who underwent LSM by TE between July 2008 and June 2011, we used Cox regression to determine the independent association between liver stiffness and death or hepatic complications (decompensation, hepatocellular carcinoma, and liver transplantation. The performance of LSM to predict complications was determined using the c-statistic.Among 2,052 patients (median age 51 years, 65% with hepatitis B or C, 87 patients (4.2% died or developed a hepatic complication during a median follow-up period of 15.6 months (interquartile range, 11.0-23.5 months. Patients with complications had higher median liver stiffness than those without complications (13.5 vs. 6.0 kPa; P<0.00005. The 2-year incidence rates of death or hepatic complications were 2.6%, 9%, 19%, and 34% in patients with liver stiffness <10, 10-19.9, 20-39.9, and ≥40 kPa, respectively (P<0.00005. After adjustment for potential confounders, liver stiffness by TE was an independent predictor of complications (hazard ratio [HR] 1.05 per kPa; 95% confidence interval [CI] 1.03-1.06. The c-statistic of liver-stiffness for predicting complications was 0.80 (95% CI 0.75-0.85. A liver stiffness below 20 kPa effectively excluded complications (specificity 93%, negative predictive value 97%; however, the positive predictive value of higher results was sub-optimal (20%.Liver stiffness by TE accurately predicts the risk of death or hepatic complications in patients with chronic liver disease. TE may facilitate the estimation of prognosis and guide management of these patients.

    The aim of this study was to determine the clinical performances of noninvasive serum markers for the prediction of liver fibrosis in chronic viral liver diseases. We analyzed a total of 225 patients with chronic viral liver diseases (180 with hepatitis B virus, 43 with hepatitis C virus, and 2 with hepatitis B+C virus) who underwent a liver biopsy procedure at the Hanyang University Guri Hospital between March 2002 and February 2007. Serum was also obtained at the time of liver biopsy. Liver fibrosis was staged according to the scoring system proposed by the Korean Study Group for the Pathology of Digestive Diseases. Various noninvasive serum markers were evaluated, including the aspartate aminotransferase (AST)/alanine aminotransferase (ALT) ratio (AAR), age-platelet (AP) index, AST/platelet ratio index (APRI), cirrhosis discriminant score (CDS), platelet count, hyaluronic acid (HA), and type IV collagen. There were 17, 40, 61, 74, and 33 patients at stages F0, F1, F2, F3, and F4, respectively. The overall diagnostic accuracies of each marker, as determined by the area under receiver operating characteristics curves, were APRI=0.822, CDS=0.776, platelet count=0.773, AP index=0.756, HA=0.749, type IV collagen=0.718, and AAR=0.642 for predicting significant fibrosis (> or =F2); and CDS=0.835, platelet count=0.795, AP index=0.794, HA=0.766, AAR=0.711, type IV collagen=0.697, and APRI=0.691 for predicting extensive fibrosis (> or =F3). All noninvasive serum markers evaluated in this study were useful for predicting significant or extensive liver fibrosis in chronic viral liver diseases. In particular, APRI was most useful for the prediction of significant fibrosis, and CDS was most useful for the prediction of extensive fibrosis.

    The metabolism of transferrin was studied using purified 125 I-labeled transferrin in 11 alcoholic patients; six with fatty liver and five with cirrhosis. Six healthy subjects whose alcohol intake was les than 40 gm daily were studied as a control group. There were no significant differences in the mean fractional catabolic rate and plasma volume in the alcoholic groups when compared with control subjects. A significantly decreased mean serum transferrin concentration was found in the alcoholic cirrhotic patients (1.8 +/- 0.3 gm per liter vs. 2.9 +/- 0.2; p less than 0.01), resulting from diminished total body synthesis (0.9 +/- 0.2 mg per kg per hr vs. 1.8 +/- 0.2; p less than 0.01). In contrast, in the patients with alcoholic fatty liver, the mean total body transferrin synthesis (2.4 +/- 0.3 mg per kg per hr) was significantly increased when compared with controls (p less than 0.05). For all the alcoholic patients, the serum transferrin correlated with transferrin synthesis (r = +0.70; p less than 0.01) but the serum iron did not. These results suggest that, in alcoholic cirrhosis, transferrin synthesis is decreased, probably reflecting diminished synthetic capacity by the liver. In contrast, in patients with alcoholic fatty liver, transferrin turnover is accelerated

    Chronic viral liver disease is often associated with other conditions. Diabetes mellitus (DM) is frequently reported in this context and may play a role in the progression of the liver disease to hepatocellular carcinoma (HCC). Renal disease is also an important extrahepatic manifestation of hepatitis viral infection and its presence is associated with poor prognosis and management issues. Our study had multiple purposes: to determine the frequency of the association between chronic viral liver disease and diabetes mellitus, evaluate the potential of diabetes mellitus as a risk factor for HCC and assess an eventual renal involvement. We included in our study a number of 246 patients with chronic liver disease, from whom 136 were diagnosed with chronic viral hepatitis and 110 with viral liver cirrhosis. These patients were assessed by using a clinical examination and a series of tests, including serum transaminase levels, serum bilirubin, serum albumin, markers of cholestasis, fasting plasma glucose levels, serum creatinine, urea, albuminuria, Addis-Hamburger test, electrophoresis of urinary proteins, abdominal ultrasound and, in some cases, CT examination. We obtained the following results: diabetes mellitus is often associated with chronic liver disease of viral etiology, having been identified in 18.29% of the patients in our study. Age above 60 in patients with chronic hepatitis (p=0.013diabetes mellitus. Renal disease was present in 13.4% of the patients with chronic liver disease and it was especially associated with liver cirrhosis and hepatitis C virus. The most common form of renal injury was glomerulonephritis. Acute kidney injury was diagnosed only in cirrhotic patients as hepatorenal syndrome, occurring in 7.27% of the subjects, while chronic kidney disease was identified only in two cases of chronic viral hepatitis. Four patients in our study were diagnosed with HCC and none of them presented diabetes mellitus. Our study revealed that there is a

    The occurrence of a hypercoagulable state and decreasing concentration of ADAMTS 13 in late pregnancy and during the postpartum period increases the risk for a woman to develop life-threatening thrombotic thrombocytopenic purpura (TTP). This is also the time of great risk for the more common obstetric complications of preeclampsia; eclampsia; and hemolysis, elevated liver functions tests, low platelets (HELLP) syndrome. These conditions are associated with high maternal and perinatal mortality. Differential diagnosis may be difficult due to the overlapping of clinical and laboratory findings, including thrombocytopenia, microangiopathic hemolytic anemia, neurologic symptoms, and renal insufficiency, making it difficult or impossible to distinguish them from TTP. Management of microangiopathic disorders encountered during pregnancy differ; therefore, an accurate diagnosis is required. Outcomes of TTP without plasma exchange therapy (TPE) are almost uniformly fatal. Early recognition and management of symptoms with prompt and aggressive TPE is essential when TTP is suspected.

    We tested the diagnostic abilities of dynamic CT in diffuse liver diseases. The material includes 23 cases of chronic active hepatitis (CAH), 32 cases of liver cirrhosis (LC) and 15 cases with normal liver. For each case, time-density curve was obtained from the right lobe of the liver. To allow numerical evaluation of the curve, gamma variate fit techniques were employed. Changes in the curves were analyzed by comparing three parameters-rise time (RT), decay time (DT) and corrected first moment (MC)-derived from two coefficients of the fitting equation. Values of three parameters increased with the severity of the diseases reflecting prolonged curves with delayed peak and gradual downslope in damaged livers. MC values showed most significant correlation with the degree of the diseases. High MC value (>95) were associated with 30 cases of LC and 3 cases of CHA, and moderate MC value (70< MC<=95) with 19 cases of CAH and 2 controls, and low MC value (<=70) with 15 controls and a case of CAH. We conclude that dynamic CT time-density study with gamma variate fitting is useful in the differential diagnosis of the diffuse liver diseases. (author)

    Patients with advanced liver disease have an increased risk of complications, compared to healthy patients when they undergo a surgical procedure. This risk is related to the type of surgery, to the type of anesthetic used, and to the severity of the underlying liver disease. Several risk factors for liver disease should be identified prior to a procedure. Those with advanced disease should undergo specific pre-surgical diagnostic tests. The Child Pugh score, and the MELD score, are very useful to establish the surgical risk in individuals with liver disease. The Child-Pugh score is a very useful tool that correlates closely to morbidity and mortality in patients with liver disease. Mortality rates in these patients undergoing major surgery is 10, 30 and 82% for Child-Pugh scores A, B and C respectively. In order to optimize the patient's condition before surgery, a complete evaluation and management of conditions such as jaundice, coagulopathy, ascites, electrolyte abnormalities, renal insufficiency and encephalopathy must be performed. This approach helps to reduce the complication rate in these individuals

    Cardiac magnetic resonance imaging (CMR) is a useful diagnostic imaging modality in patients with known or suspected coronary artery disease (CAD). It provides unique information not available from other modalities, however, it is complex. CMR is not a single technique. Instead, it consists of multiple distinct techniques and a lack of understanding of which techniques to perform and how to interpret the findings in combination limits its efficacy and widespread use. Conversely, its multipara...

    Liver scintigraphy was performed using a newly developed radiopharmaceutical, Tc-99m-DTPA-galactosyl-human-serum-albumin (Tc-99m-GSA), which binds specifically to the receptors on the hepatic cell surface, in 15 patients with chronic liver disease. The scintigraphy was evaluated qualitatively and quantitatively, and the results were compared with those obtained from the Tc-99m-PMT or Tc-99m-sn-phytate scintigraphy, and the liver function tests. The Tc-99m-GSA scintigraphy showed clear liver images in chronic hepatitis. However, in liver cirrhosis, the liver images were not clear and the cardiac images still existed 40 minutes after administration of Tc-99m-GSA, suggesting that the image quality of the Tc-99m-GSA scintigrams may be inferior to that of Tc-99m-sn-phytate or Tc-99m-PMT in some cases of severe liver dysfunction. The time-activity curves of the heart and liver were analyzed by non-linear regression analysis. The clearance rate from plasma (Kd) were obtained from the time-activity curve of the heart, and the hepatic uptake rate (Ku), hepatic excretion rate (Ke) and peak time of hepatic uptake-excretion curve (PT) were obtained from the time-activity curve of the liver. Kd, Ku, and PT values were more significantly decreased or prolonged in the patients with chronic hepatitis. Kd, Ku, and PT values had positive correlations with the result of the serum liver function tests, ICG-R15 and ICG-K. Ku and PT values had also correlations with the histological degree of hepatic fibrosis. On the other hand, the indices obtained using Tc-99m-PMT or Tc-99m-sn-phytate did not have correlations with the histological degrees of hepatic fibrosis. It is concluded that the liver scintigraphy using Tc-99m-GSA may be useful and give different information from those with conventional liver scintigraphies in evaluating chronic liver diseases.

    Full Text Available Oxidative stress and hepatic mitochondria play a role in the pathogenesis of nonalcoholic fatty liver disease. The aim of the present study was to evaluate the role of hepatic mitochondrial dysfunction and oxidative stress in the pathogenesis of the disease. Fatty liver was induced in Wistar rats with a choline-deficient diet (CD; N = 7 or a high-fat diet enriched with PUFAs-omega-3 (H; N = 7 for 4 weeks. The control group (N = 7 was fed a standard diet. Liver mitochondrial oxidation and phosphorylation were measured polarographically and oxidative stress was estimated on the basis of malondialdehyde and glutathione concentrations. Moderate macrovacuolar liver steatosis was observed in the CD group and mild liver steatosis was observed in the periportal area in the H group. There was an increase in the oxygen consumption rate by liver mitochondria in respiratory state 4 (S4 and a decrease in respiratory control rate (RCR in the CD group (S4: 32.70 ± 3.35; RCR: 2.55 ± 0.15 ng atoms of O2 min-1 mg protein-1 when compared to the H and control groups (S4: 23.09 ± 1.53, 17.04 ± 2.03, RCR: 3.15 ± 0.15, 3.68 ± 0.15 ng atoms of O2 min-1 mg protein-1, respectively, P < 0.05. Hepatic lipoperoxide concentrations were significantly increased and the concentration of reduced glutathione was significantly reduced in the CD group. A choline-deficient diet causes moderate steatosis with disruption of liver mitochondrial function and increased oxidative stress. These data suggest that lipid peroxidation products can impair the flow of electrons along the respiratory chain, causing overreduction of respiratory chain components and enhanced mitochondrial reactive oxygen species. These findings are important in the pathogenesis of nonalcoholic fatty liver disease.

    Human liver contains an acid cholesterol ester hydrolase (CEH) of presumed lysosomal origin, but its significance is unknown. We developed a modified CEH radioassay suitable for needle biopsy specimens and measured hepatic activity of this enzyme in 69 patients undergoing percutaneous liver biopsy. Histologically normal livers hydrolyzed 5.80 +/- 0.78 SEM mumoles of cholesterol ester per hr per g of liver protein (n, 10). Values were similar in alcoholic liver disease (n, 17), obstructive jaundice (n, 9), and miscellaneous hepatic disorders (n, 21). In contrast, mean hepatic CEH activity was more than 3-fold elevated in 12 patients with acute hepatitis, 21.05 +/- 2.45 SEM mumoles per hr per g of protein (P less than 0.01). In 2 patients studied serially, CEH returned to normal as hepatitis resolved. CEH activity in all patients paralleled SGOT levels (r, 0.84; P less than 0.01). There was no correlation with serum levels of free or esterified cholesterol nor with serum activity of lecithin-cholesterol acyltransferase, the enzyme responsible for cholesterol esterification in plasma. These studies confirm the presence of CEH activity in human liver and show markedly increased activity in acute hepatitis. The pathogenesis and clinical significance of altered hepatic CEH activity in liver disease require further study.

    In 2014, the U.S. Public Health Service (USPHS) Commissioned Corps deployed to Monrovia, Liberia, to operate a 25-bed Ebola treatment unit (ETU) constructed by the U.S. Military. The ETU was named the Monrovia Medical Unit (MMU) and was constructed from an U.S. Air Force Expeditionary Medical Support (EMEDS) unit with modifications on the basis of consultation from Médecins Sans Frontières, the World Health Organization, and expert panels from the U.S. Department of Defense and Department of Health and Human Services. From November 12, 2014, to April 30, 2015, 42 patients (18 confirmed Ebola virus disease [EVD] and 24 suspected EVD) from nine countries were treated by USPHS providers at the MMU. The medications used in the MMU were primarily procured from the EMEDS 25-bed pharmacy cache. However, specific formulary additions were made for treatment of EVD. Using the MMU pharmacy dispensing data, we compared and contrasted the medications used in the MMU with recommendations in published EVD treatment guidelines for austere settings. After comparing and contrasting the MMU pharmacy dispensing data with publications with EVD medication recommendations applicable to resource-limited settings, 101 medications were included in the USPHS Essential Medications for the Management of EVD List (EML) for an austere, isolated clinical environment. Because Ebola outbreaks often occur in remote areas, proactive planning, improved preparedness, and optimal patient care for EVD are needed, especially in the context of austere environments with a scarcity of resources. We developed the EML to assist in the planning for future Ebola outbreaks in a remote clinical environment and to provide a list of medications that have been used in an ETU. The EML is a comprehensive medication list that builds on the existing publications with EVD treatment recommendations applicable to supply-constrained clinical environments. As well, it is a resource for the provision of medications when

    Full Text Available The impact of marijuana on nonalcoholic fatty liver disease (NAFLD is largely unknown. We studied the association between marijuana and NAFLD utilizing cross-sectional data from the National Health and Nutrition Examination Survey (NHANES from 2005-2014 and NHANES III (1988-1994.Suspected NAFLD was diagnosed if serum alanine aminotransferase (ALT was > 30 IU/L for men and > 19 IU/L for women in the absence of other liver diseases (NHANES 2005-2014. In NHANES III cohort, NAFLD was defined based on ultrasonography.Of the 14,080 (NHANES 2005-2014 and 8,286 (NHANES III participants, prevalence of suspected NAFLD and ultrasonographically-diagnosed NAFLD were inversely associated with marijuana use (p < 0.001. Compared to marijuana-naïve participants, marijuana users were less likely to have suspected NAFLD (odds ratio [OR]: 0.90, 95% confidence interval [CI]: 0.82-0.99 for past user; OR: 0.68, 95% CI: 0.58-0.80 for current user and ultrasonographically-diagnosed NAFLD (OR: 0.75, 95% CI: 0.57-0.98 for current user in the age, gender, ethnicity-adjusted model. On multivariate analysis, the ORs for suspected NAFLD comparing current light or heavy users to non-users were 0.76 (95% CI 0.58-0.98 and 0.70 (95% CI 0.56-0.89, respectively (P for trend = 0.001 with similar trends in ultrasonographically-diagnosed NAFLD (OR: 0.77, 95% CI: 0.59-1.00 for current user; OR: 0.71, 95% CI: 0.51-0.97 for current light user. In insulin resistance-adjusted model, marijuana use remained an independent predictor of lower risk of suspected NAFLD.In this nationally representative sample, active marijuana use provided a protective effect against NAFLD independent of known metabolic risk factors. The pathophysiology is unclear and warrants further investigation.

    Nonalcoholic fatty liver disease (NAFLD) encompasses a spectrum of abnormalities that can range from bland liver fat (steatosis), to hepatic inflammation and liver injury (steatohepatitis). It is estimated that NAFLD will become the principal cause of liver disease in Western nations and the leading indication for liver transplantation. Advancements in disease recognition and management are therefore paramount. Although the development of new, reliable drug therapies is vital, lifestyle interventions remain the most effective treatment modality. In addition to weight loss as a primary measure of treatment success, there is growing recognition that other endpoints, including the prevention or delay of diabetes onset, reduced cardiovascular events, prevention of cancer, and improved overall mortality, are equally important outcomes that can be independently modified by lifestyle change. Moreover, NAFLD is inextricably part of a complex, systemic disease process that is linked with deeply entrenched maladaptive lifestyle behaviors. Thus, a holistic, multidisciplinary, and individualized approach to disease management will be the key to achieving any realistic population-level change.

    Non alcoholic fatty liver disease is the hepatic manifestation of metabolic syndrome, and the most common liver disease. Its more aggressive form is the non alcoholic steatohepatitis. Multiple genetic and environmental factors lead to the accumulation of triglicerides and the inflammatory cascade. High fat diet, obesity, adipocyte dysfunction with cytokine production, insulin resistance and increased lipolysis with free fatty acid flux into the liver - all are the drivers of liver cell injury. Activation of inflammasome by damage- or pathogen-associated molecular patterns results in "steril inflammation" and immune response, while the hepatic stellate cells and progenitor cells lead to fibrogenesis. Small intestinal bacterial overgrowth and gut dysbiosis are also of pivotal importance in the inflammation. Among the susceptible genetic factors, mutations of patatin-like phospholipase domain containing 3 and the transmembrane 6 superfamily 2 genes play a role in the development and progression of the disease, similarly as do epigenetic regulators such as microRNAs and extracellular vesicles. Better understanding of the pathogenesis of non alcoholic fatty liver disease may identify novel therapeutic agents that improve the outcome of the disease. Orv Hetil. 2017; 158(23): 882-894.

  1. New Insights from Rodent Models of Fatty Liver Disease

    Science.gov (United States)

    2011-01-01

    Abstract Rodent models of fatty liver disease are essential research tools that provide a window into disease pathogenesis and a testing ground for prevention and treatment. Models come in many varieties involving dietary and genetic manipulations, and sometimes both. High-energy diets that induce obesity do not uniformly cause fatty liver disease; this has prompted close scrutiny of specific macronutrients and nutrient combinations to determine which have the greatest potential for hepatotoxicity. At the same time, diets that do not cause obesity or the metabolic syndrome but do cause severe steatohepatitis have been exploited to study factors important to progressive liver injury, including cell death, oxidative stress, and immune activation. Rodents with a genetic predisposition to overeating offer yet another model in which to explore the evolution of fatty liver disease. In some animals that overeat, steatohepatitis can develop even without resorting to a high-energy diet. Importantly, these models and others have been used to document that aerobic exercise can prevent or reduce fatty liver disease. This review focuses primarily on lessons learned about steatohepatitis from manipulations of diet and eating behavior. Numerous additional insights about hepatic lipid metabolism, which have been gained from genetically engineered mice, are also mentioned. Antioxid. Redox Signal. 15, 535–550. PMID:21126212

    We compared light pen (LPEN) and Region of Interest (ROI) computer methods in determining spleen-to-liver (S/L) ratios both in anterior and posterior images in various liver diseases. The S/L ratio was independent of age or type of colloid used (equal particle size provided). Results with corresponding LPEN and ROI programs did not differ significantly from each other. The sensitivity and specificity were tested and the anterior view yielded somewhat better results than the posterior view but the best results were obtained when both projections were used. The sensitivity for all liver diseases was 60% and the corresponding specificity 93%. In hepatocellular diseases the sensitivity was 80-100%, but the S/L ratio had only 37% sensitivity for hepatic metastases. Hepatomegaly in the anterior view was found in 67% of fatty liver cases, in 25% of cirrhosis cases, in 20% of hepatitis and in 25% of metastatic livers. Splenomegaly was noted in 39-54% of patients with hepatocellular diseases but only in 4-10% of metastatic diseases. (orig.) [de

    To evaluate the diagnostic value of sonographic irregularities of liver surface in the differentiation of chronic liver disease. Fifty-eight patients with either chronic hepatitis or early stage of liver cirrhosis were examined with 5 MHz linear array transducer by observing the liver surface.We compared the sonographic findings with peritoneoscopic and pathologic findings. Thirty-five patients with smooth surface showed variable pathological results, including chronic active and persistent hepatitis, inactive hepatitis and alcoholic hepatitis without any evidence of cirrhosis. Nineteen patients with micronodules mostly revealed chronic active hepatitis and cirrhosis. All 4 patients with macronodules were proved pathologically ascirrhosis. High resolution ultrasonography(HRUS) showed smooth liver surface in 35 patients(60.3%),micronodular surface in l9(32.8%), and macronodular surface in 4 (6.9%). Twenty-one cases(60.0%) among 35 patients with smooth surface were peritoneoscopically normal and 12 cases(34.3%) showed dimpling surface. However among l9 patients with micronodular surface, only 5 cases(26.3%) showed micronodular surface on peritoneoscopy. while 8 cases(42.l%) showed nracronodular surface and 6 cases(3l.6%) dimpling surface. All 4 patients with macronodulesrevealed peritoneoscopically nracronodular surface. Observation of liver surface by HRUS was useful in predicting the progression of chronic hepatitis to cirrhosis. However, it was not helpful in the differentiation between normal liver and chronic hepatrtrs

    Full Text Available Objective: To analyse the various abnormal transabdominal ultrasound findings in patients with clinical suspicion of chronic liver disease in our environment with a view of comparing our findings with other existing literatures. Methods: A total of 61 consecutive patients with clinical signs and symptoms of chronic liver disease attending medical outpatient clinic at the Department of Medicine, Usmanu Danfodiyo University, Teaching Hospital Sokoto and Federal Medical Centre Birnin Kebbi were scanned at Radiology Departments for any abnormal intraabdominal findings from May 2011 to April 2012. All the patients were scanned with Apogee 800 plus (Japan 2002 and Concept D (Dynamic Imaging Scotland Ultrasound scanners with a variable frequency probes at 5-12 MHz. Results: A total of 61 abdominal ultrasounds were performed during this study period. All the cases met the inclusion criteria. The mean age was (46.0依12.6 years (ranged 50 years. The mean liver size was (13.25依1.48 cm (ranged 11 cm and (14.00依0.77 cm (ranged 0.77 cm for right and left lobe respectively. The mean spleen size was (15.90依1.22 cm (ranged 6 cm. The sex distribution was males 43 (70.49% and females 18 (29.5%. Of the 61 cases included, the indication for the abdominal ultrasonography were hepatitis 1 (1.6%, liver cirrhosis 20 (50.82%, obstructive jaundice 2 (3.28%, chronic liver disease 25 (40.98% and chronic abdominal swelling 2 (3.2%. Conclusions: In conclusion, our study has demonstrated various abnormal transabdominal ultrasound findings in patients suspected with chronic liver disease in our locality. Ultrasound is useful in the diagnosis of chronic liver disease in daily clinical practice. However, the sensitivity can be improved if a high frequency probe is used and done by experienced and dedicated operators. Liver biopsy remains the gold standard especially when patients are clinically asymptomatic.

    In the clinical practice, the evaluation of myocardial perfusion by using Computed Tomography (CT) Imaging is usually performed visually or semi-quantitatively. The scarcity of quantitative perfusion data not always allows a proper diagnose of patients which are suspected of suffering from some diseases, such as Ischemic Heart Disease (IHD). In this work, a clinical tool for the automatic quantification of myocardial perfusion in patients with suspected IHD is proposed. Myocardial perfusion is assessed based on a combined diagnosis protocol (CT/CTP protocol) which involves the acquisition of two contrastenhanced CT images, one obtained at rest and another acquired under pharmacological stress. The clinical tool allows the automatic quantification of perfusion in different myocardial segments defined according to the 16-AHA-segmentation model of the left ventricle, by providing the mean of Hounsfield Units in those regions. Based on this analysis, the clinicians can compare the values at baseline and at hyperemia, and they can better determine hypoperfusion defects in patients with IHD. The validation of the clinical tool was performed by comparing automatic and manual perfusion measurements of 10 patients with suspected IHD who were previously assessed with Single Photon Emission Computed Tomography (SPECT) for perfusion analysis. A strong linear correlation was found between the automatic and manual results. Afterwards, perfusion defects obtained from CT/CTP protocol were compared to perfusion defects from SPECT, to assess the applicability of this clinical tool for the diagnosis of IHD. (Author)

    Full Text Available The rapid increase in fatty liver disease (FLD incidence is attributed largely to genetic and lifestyle factors; however, environmental toxicants are a frequently overlooked factor that can modify the effects of more common causes of FLD. Chronic exposure to inorganic arsenic (iAs is associated with liver disease in humans and animal models, but neither the mechanism of action nor the combinatorial interaction with other disease-causing factors has been fully investigated. Here, we examined the contribution of iAs to FLD using zebrafish and tested the interaction with ethanol to cause alcoholic liver disease (ALD. We report that zebrafish exposed to iAs throughout development developed specific phenotypes beginning at 4 days post-fertilization (dpf, including the development of FLD in over 50% of larvae by 5 dpf. Comparative transcriptomic analysis of livers from larvae exposed to either iAs or ethanol revealed the oxidative stress response and the unfolded protein response (UPR caused by endoplasmic reticulum (ER stress as common pathways in both these models of FLD, suggesting that they target similar cellular processes. This was confirmed by our finding that arsenic is synthetically lethal with both ethanol and a well-characterized ER-stress-inducing agent (tunicamycin, suggesting that these exposures work together through UPR activation to cause iAs toxicity. Most significantly, combined exposure to sub-toxic concentrations of iAs and ethanol potentiated the expression of UPR-associated genes, cooperated to induce FLD, reduced the expression of as3mt, which encodes an arsenic-metabolizing enzyme, and significantly increased the concentration of iAs in the liver. This demonstrates that iAs exposure is sufficient to cause FLD and that low doses of iAs can potentiate the effects of ethanol to cause liver disease.

    Full Text Available Glycyrrhizic acid (GA is a triterpene glycoside found in the roots of licorice plants (Glycyrrhiza glabra. GA is the most important active ingredient in the licorice root, and possesses a wide range of pharmacological and biological activities. GA coupled with glycyrrhetinic acid and 18-beta-glycyrrhetic acid was developed in China or Japan as an anti-inflammatory, antiviral, and antiallergic drug for liver disease. This review summarizes the current biological activities of GA and its medical applications in liver diseases. The pharmacological actions of GA include inhibition of hepatic apoptosis and necrosis; anti-inflammatory and immune regulatory actions; antiviral effects; and antitumor effects. This paper will be a useful reference for physicians and biologists researching GA and will open the door to novel agents in drug discovery and development from Chinese herbs. With additional research, GA may be more widely used in the treatment of liver diseases or other conditions.

    Contrary to well-recognized bleeding diathesis in chronic liver disease, thrombotic events can occur in these patients due to reduction or loss of synthesis of anticoagulant proteins. Forty-seven consecutive patients with end-stage liver disease (ESLD) were investigated for activity of protein C, protein S, antithrombin, and factor V Leiden mutation. Forty-two (89.4%) patients had low levels of at least 1 while 33 (70.2%) patients were deficient for all anticoagulant proteins studied. Forty-six (97.9%) patients were negative for factor V Leiden mutation. The deficiencies were more marked in hepatitis C virus-positive patients and patients with model for end-stage liver disease (MELD) score >15. Six (12.8%) patients had portal vein thrombosis (PVT), and all had diminished protein S activity. In conclusions, deficiency of anticoagulant proteins occur in early phase of chronic liver disease. The severity of deficiency is proportional to the severity of liver disease. Despite the high prevalence of hypercoagulability, the incidence of PVT is low. Further studies with larger cohort of patients are needed to support these conclusions and to study other associated factors.

    Full Text Available There is a clear need for better biomarkers of drug-induced-liver-injury (DILI.We aimed to evaluate the possible prognostic value of ActiTest and FibroTest proteins apoliprotein-A1, haptoglobin and alpha-2-macroglobulin, in patients with DILI.We analyzed cases and controls included in the IMI-SAFE-T-DILI European project, from which serum samples had been stored in a dedicated biobank. The analyses of ActiTest and FibroTest had been prospectively scheduled. The primary objective was to analyze the performance (AUROC of ActiTest components as predictors of recovery outcome defined as an ALT <2x the upper limit of normal (ULN, and BILI <2x ULN.After adjudication, 154 patients were considered to have DILI and 22 were considered to have acute liver injury without DILI. A multivariate regression analysis (ActiTest-DILI patent pending combining the ActiTest components without BILI and ALT (used as references, apolipoprotein-A1, haptoglobin, alpha-2-macroglobulin and GGT, age and gender, resulted in a significant prediction of recovery with 67.0% accuracy (77/115 and an AUROC of 0.724 (P<0.001 vs. no prediction 0.500. Repeated apolipoprotein-A1 and haptoglobin remained significantly higher in the DILI cases that recovered (n = 65 versus those that did not (n = 16, at inclusion, at 4-8 weeks and at 8-12 weeks. The same results were observed after stratification on APAP cases and non-APAP cases.We identified that apolipoprotein-A1 and haptoglobin had significant predictive values for the prediction of recovery at 12 weeks in DILI, enabling the construction of a new prognostic panel, the DILI-ActiTest, which needs to be independently validated.

    Knowing how to prevent and treat diabetes mellitus (DM) earlier is essential to improving outcomes. Through participating in synthesis and catabolism of glycogen, the liver helps to regulate glucose homeostasis. Viral related liver diseases are associated with glycometabolism disorders, which means effective management of viral liver diseases may be a therapeutic strategy for DM. The present article reviews the correlation between DM and liver diseases to give an update of the management of DM rooted by viral liver diseases.

    Full Text Available Introduction: Post-transplant lymphoproliferative syndrome (PTLD is a rare and potentially life-threatening complication after liver transplantation. The aim of this study was to analyze the clinicopathologic features related to PTLD in a single institution after liver transplantation. Methods: Observational study where we have retrospectively analyzed 851 cases who underwent liver transplantation. Ten cases have developed PTLD. Their clinical-pathological characteristics and the treatment received have been analyzed. Results: PTLD incidence was 1.2% (10/851. The mean time from liver transplantation to PTLD diagnosis was 36 months (range 1.2 to 144 months. PTLD localization was extranodal in all cases, the most frequent location being intestinal. Seven cases showed a monomorphic lymphoma which in all cases was differentiated B cell lymphomas. Fifty per cent of the series were seropositive for Epstein-Barr virus. Five patients were alive at the time of the review. Among these patients, we observed three cases of complete remission and two cases of disease stabilization. The death rate was higher in the first year after diagnosis of PTLD. Conclusion: PTLD is a rare complication after liver transplantation, but it may pose a threat to the life of a liver transplant recipient. It is essential to identify patients at risk, to establish an early diagnosis and treatment that can change the outcome of the disease.

    In order to evaluate computed tomography (CT) in the diagnosis of liver disease, 90 cases of diffuse parenchymal diseases and 37 cases of mass lesions were examined with a GE 8800 CT scanner. Abnormal CT findings in liver cirrhosis were characterized by splenomegaly, uneven liver margin and asites. Atrophy of right lobe and enlargement of left lobe could not be easily recognized on CT scan, compared with nuclear imaging. CT values of the liver were decreased and the ratios of CT values of the liver to those of the spleen were less than 0.9 in all cases with fatty liver. Jaundice in acute viral hepatitis can be easily differentiated from obstructive jaundice on CT scan because of observing no dilatation of intrahepatic bile duct. CT was superior in detecting space-occupying lesions to nuclear imaging and was more specific in that it was able to differentiate cystic from solid lesions. However, it was almost impossible to make a histological diagnosis of solid lesions even on CT scan.

    Non-alcoholic fatty liver disease (NAFLD) covers a wide spectrum of liver pathology--from steatosis alone, through the necroinflammatory disorder of non-alcoholic steatohepatitis (NASH) to cirrhosis and liver cancer. NAFLD/NASH is mostly related with visceral adiposity, obesity, type 2 diabetes melitus (DM t.2) and metabolic syndrome. Pathogenetic concepts of NAFLD include overnutrition and underactivity, insulin resistance (IR) and genetic factor. The prevalence of NAFLD has been estimated to be 17-33% in some countries, NASH may be present in about 1/3 of such cases, while 20-25% of NASH cases could progress to cirrhosis. NAFLD is now recognized as one of the most frequent reason of liver tests elevation without clinical symptoms. Insulin resistance is considering as having a central role in NAFLD pathogenesis. In hepatocytes, IR is related to hyperglycaemia and hyperinsulinaemia, formation of advanced glycation end-products, increased free fatty acids and their metabolites, oxidative stress and altered profiles of adipocytokines. Early stages of fatty liver are clinically silent and include elevation of ALT and GGTP, hyperechogenic liver in USG and/or hepatomegaly. Among clinical symptoms, abdominal discomfort is relatively common as well as chronic fatigue. NAFLD/NASH is not a benign disease, progressive liver biopsy have shown histological progression of fibrosis in 32%, the estimated rate of cirrhosis development is 20% and a liver--related death is 12% over 10 years. No treatment has scientifically proved to ameliorate NAFLD or to avoid its progression. The various therapeutic alternatives are aimed at interfering with the risk factors involved in the pathogenesis of the disorder in order to prevent the progression to end-stage liver disease. The most important therapeutic measure is increasing insulin sensitivity by an attempt to change a lifestyle mostly by dieting and physical activity in order to loose weight. The most used agent is metformin, the others

    Portal circulation has been evaluated by per-rectal portal scintigraphy in 21 controls and in 30 pts affected by chronic liver diseases. Tc99m-pertechnetate (10 mci) was given through a Nelaton's catheter in the upper rectum; a per-rectal portal shunt index (SI) was calculated. A relevant overlap is evident between controls and CHP pts; no overlap exists between controls and B or C graded cirrhosis. We conclude that the technique may be suggested to monitor the course of chronic liver diseases and different therapeutic regimens. (orig.) [de

    Non-alcoholic fatty liver disease (NAFLD) comprises a series of histologically lesions similar to those induced by alcohol consumption in people with very little or no liver damage. The importance of NAFLD is its high prevalence in the Western world and, from the point of view of the liver, in its gradual progression from steatosis to steatohepatitis, cirrhosis, and liver cancer. During the last decade it has been observed that NAFLD leads to an increased cardiovascular risk with acceleration of arteriosclerosis and events related to it, being the main cause of its morbidity and mortality. This review, updated to January 2016, consists of two parts, with the first part analysing the association of NAFLD with cardiovascular disease.

  4. Gut Microbiota and Host Reaction in Liver Diseases

    2015-10-01

    Full Text Available Although alcohol feeding produces evident intestinal microbial changes in animals, only some alcoholics show evident intestinal dysbiosis, a decrease in Bacteroidetes and an increase in Proteobacteria. Gut dysbiosis is related to intestinal hyperpermeability and endotoxemia in alcoholic patients. Alcoholics further exhibit reduced numbers of the beneficial Lactobacillus and Bifidobacterium. Large amounts of endotoxins translocated from the gut strongly activate Toll-like receptor 4 in the liver and play an important role in the progression of alcoholic liver disease (ALD, especially in severe alcoholic liver injury. Gut microbiota and bacterial endotoxins are further involved in some of the mechanisms of nonalcoholic fatty liver disease (NAFLD and its progression to nonalcoholic steatohepatitis (NASH. There is experimental evidence that a high-fat diet causes characteristic dysbiosis of NAFLD, with a decrease in Bacteroidetes and increases in Firmicutes and Proteobacteria, and gut dysbiosis itself can induce hepatic steatosis and metabolic syndrome. Clinical data support the above dysbiosis, but the details are variable. Intestinal dysbiosis and endotoxemia greatly affect the cirrhotics in relation to major complications and prognosis. Metagenomic approaches to dysbiosis may be promising for the analysis of deranged host metabolism in NASH and cirrhosis. Management of dysbiosis may become a cornerstone for the future treatment of liver diseases.

    Non-alcoholic fatty liver disease (NAFLD) is the most common chronic liver disease. It is characterized by a wide spectrum of hepatic changes, which may progress to non-alcoholic steatohepatitis (NASH) and cirrhosis. NAFLD is considered a hepatic manifestation of metabolic syndrome; however, mechanisms underlying the onset and progression of NAFLD are still unclear. Resident and recruited macrophages are key players in the homeostatic function of the liver and in the progression of NAFLD to NASH. Progress has been made in understanding the molecular mechanisms underlying the polarized activation of macrophages. New NAFLD therapies will likely involve modification of macrophage polarization by restraining M1 activation or driving M2 activation. Carotenoids are potent antioxidants and anti-inflammatory micronutrients that have been used to prevent and treat NAFLD. In addition to their antioxidative action, carotenoids can regulate macrophage polarization and thereby halt the progression of NASH. In this review, we summarize the molecular mechanisms of macrophage polarization and the function of liver macrophages/Kupffer cells in NAFLD. From our review, we propose that dietary carotenoids, such as β-cryptoxanthin and astaxanthin, be used to prevent or treat NAFLD through the regulation of macrophage polarization and liver homeostasis.

    Full Text Available Invasive fungal diseases (IFDs are an important factor affecting the prognosis of patients with severe liver diseases, and their early diagnosis remains a challenge for clinicians. The four most commonly seen IFDs are candidiasis, aspergillosis, cryptococcosis, and pneumocystis pneumonia. We should pay attention to the risk of developing IFDs in patients with severe liver diseases during clinical management. Particularly, early diagnosis and proper treatment of IFDs are important in high-risk patients. These are vital to improving the prognosis of patients with severe liver diseases.

    Mitochondrial diseases comprise a diverse set of clinical disorders that affect multiple organ systems with varying severity and age of onset. Due to their clinical and genetic heterogeneity, these diseases are difficult to diagnose. We have developed a targeted exome sequencing approach to improve our ability to properly diagnose mitochondrial diseases and apply it here to an individual patient. Our method targets mitochondrial DNA (mtDNA) and the exons of 1,600 nuclear genes involved in mitochondrial biology or Mendelian disorders with multi-system phenotypes, thereby allowing for simultaneous evaluation of multiple disease loci. Targeted exome sequencing was performed on a patient initially suspected to have a mitochondrial disorder. The patient presented with diabetes mellitus, diffuse brain atrophy, autonomic neuropathy, optic nerve atrophy, and a severe amnestic syndrome. Further work-up revealed multiple heteroplasmic mtDNA deletions as well as profound thiamine deficiency without a clear nutritional cause. Targeted exome sequencing revealed a homozygous c.1672C > T (p.R558C) missense mutation in exon 8 of WFS1 that has previously been reported in a patient with Wolfram syndrome. This case demonstrates how clinical application of next-generation sequencing technology can enhance the diagnosis of patients suspected to have rare genetic disorders. Furthermore, the finding of unexplained thiamine deficiency in a patient with Wolfram syndrome suggests a potential link between WFS1 biology and thiamine metabolism that has implications for the clinical management of Wolfram syndrome patients.

    There are conflicting results claiming that Alzheimer disease signature neurodegeneration may be more, less, or similarly advanced in individuals with β-amyloid peptide (Aβ)-negative (Aβ-) suspected non-Alzheimer disease pathophysiology (SNAP) than in Aβ-positive (Aβ+) counterparts. To examine patterns of neurodegeneration in individuals with SNAP compared with their Aβ+ counterparts. A longitudinal cohort study was conducted among individuals with mild cognitive impairment (MCI) and cognitively normal individuals receiving care at Alzheimer's Disease Neuroimaging Initiative sites in the United States and Canada for a mean follow-up period of 30.5 months from August 1, 2005, to June 30, 2015. Several neurodegeneration biomarkers and longitudinal cognitive function were compared between patients with distinct SNAP (Aβ- and neurodegeneration-positive [Aβ-N+]) subtypes and their Aβ+N+ counterparts. Participants were classified according to the results of their florbetapir F-18 (Aβ) positron emission tomography and their Alzheimer disease-associated neurodegeneration status (temporoparietal glucose metabolism determined by fluorodeoxyglucose F 18 [FDG]-labeled positron emission tomography and/or hippocampal volume [HV] determined by magnetic resonance imaging: participants with subthreshold HV values were regarded as exhibiting hippocampal volume atrophy [HV+], while subthreshold mean FDG values were considered as FDG hypometabolism [FDG+]). The study comprised 265 cognitively normal individuals (135 women and 130 men; mean [SD] age, 75.5 [6.7] years) and 522 patients with MCI (225 women and 297 men; mean [SD] age, 72.6 [7.8] years). A total of 469 individuals with MCI had data on neurodegeneration biomarkers; of these patients, 107 were Aβ-N+ (22.8%; 63 FDG+, 82 HV+, and 38 FDG+HV+) and 187 were Aβ+N+ (39.9%; 135 FDG+, 147 HV+, and 95 FDG+HV+ cases).

    To assess significance of serum adipokines to determine the histological severity of non-alcoholic fatty liver disease. Patients with persistent elevation in serum aminotransferase levels and well-defined characteristics of fatty liver at ultrasound were enrolled. Individuals with a history of alcohol consumption, hepatotoxic medication, viral hepatitis or known liver disease were excluded. Liver biopsy was performed to confirm non-alcoholic liver disease (NAFLD). The degrees of liver steatosis, lobular inflammation and fibrosis were determined based on the non-alcoholic fatty liver activity score (NAS) by a single expert pathologist. Patients with a NAS of five or higher were considered to have steatohepatitis. Those with a NAS of two or lower were defined as simple fatty liver. Binary logistic regression was used to determine the independent association of adipokines with histological findings. Receiver operating characteristic (ROC) analysis was employed to determine cut-off values of serum adipokines to discriminate the grades of liver steatosis, lobular inflammation and fibrosis. Fifty-four participants aged 37.02 ± 9.82 were enrolled in the study. Higher serum levels of visfatin, IL-8, TNF-α levels were associated independently with steatosis grade of more than 33% [β = 1.08 (95%CI: 1.03-1.14), 1.04 (95%CI: 1.008-1.07), 1.04 (95%CI: 1.004-1.08), P < 0.05]. Elevated serum IL-6 and IL-8 levels were associated independently with advanced lobular inflammation [β = 1.4 (95%CI: 1.09-1.8), 1.07 (95%CI: 1.003-1.15), P < 0.05]. Similarly, higher TNF-α, resistin, and hepcidin levels were associated independently with advanced fibrosis stage [β = 1.06 (95%CI: 1.002-1.12), 19.86 (95%CI: 2.79-141.19), 560.72 (95%CI: 5.98-5255.33), P < 0.05]. Serum IL-8 and TNF-α values were associated independently with the NAS score, considering a NAS score of 5 as the reference value [β = 1.05 (95%CI: 1.01-1.1), 1.13 (95%CI: 1.04-1.22), P < 0.05].

    The modern achievements in the clinical study and diagnosis of liver diseases has definitely been associated with the application of whole body computer tomography (CT) in the practice. The diagnostic possibilities of the method come from high contrast and spacial disjunctive capabilities. Visualization of local lesions is associated with their size and the differences in their densitometric compactness from that of the normal parenchyma. The advantages of computer tomography in the diagnosis of liver diseases is discussed. They are associated with the possibilities for densitometric analysis of the pathologic changes, which opens a way for a probable qualitative diagnosis. Diffuse processes in the liver are relative indication for performing computer tomography. Examination under conditions of contrast amplification is indicated in cases when the nature of the lesion has to be specified and a ''negative'' result does not concur with the clinical manifestations.

    Sixty-five patients with various diseases of the liver were examined by CT and scintigraphy. We found the following preliminary conclusions: diffusely infiltrative and hepatocellular diseases of the liver, espacially cirrhosis, are recognized on CT by shape and contour rather than by density values. In these cases, scintigraphy provides important information about the function of the parenchyma. In space-occupying processes, a close correlation exists between CT and scintigraphy. In the investigation of liver metastases in advanced stages, CT and radionuclide studies proved to be nearly identical in accuracy. The advantages of CT consist in the possibility of showing more morphologic detail of adjacent organs and in possessing better spatial resolution. (orig.) 891 MG/orig. 892 MB [de

  13. Diagnosis of alpha-1-antitrypsin deficiency by DNA analysis of children with liver disease

    Directory of Open Access Journals (Sweden)

    De TOMMASO Adriana Maria Alves

    2001-01-01

    Full Text Available Background - Alpha-1-antitrypsin deficiency is a genetic disorder which is transmitted in a co-dominant, autosomal form. Alpha-1-antitrypsin deficiency affects mainly the lungs and the liver leading, in the latter case, to neonatal cholestasis, chronic hepatitis or cirrhosis. A precise diagnosis of Alpha-1-antitrypsin deficiency may be obtained by biochemical or molecular analysis. Objective - The purpose of this study was to use DNA analysis to examine the presence of an alpha-1-antitrypsin deficiency in 12 children suspected of having this deficiency and who showed laboratory and clinical characteristics of the disease. Patients and Methods - Twelve patients, aged 3 months to 19 years, who had serum alpha-1-antitrypsin levels lower than normal and/or had hepatic disease of undefined etiology were studied. The mutant alleles S and Z of the alpha-1-antitrypsin gene were investigated in the 12 children. Alpha-1-antitrypsin gene organization was analyzed by amplification of genoma through the polymerase chain reaction and digestion with the restriction enzymes Xmnl (S allele and Taq 1 (Z allele. Results - Seven of the 12 patients had chronic liver disease of undefined etiology and the other five patients had low serum levels of alpha-1-antitrypsin as well as a diagnosis of neonatal cholestasis and/or chronic liver disease of undefined etiology. Five of the 12 patients were homozygous for the Z allele (ZZ and two had the S allele with another allele (*S different from Z. Conclusion - These results show that alpha-1-antitrypsin deficiency is relatively frequent in children with chronic hepatic disease of undefined etiology and/or low alpha-1-antitrypsin levels (41.6%. A correct diagnosis is important for effective clinical follow-up and for genetic counseling.

    Nonalcoholic fatty liver disease (NAFLD) is the most common cause of chronic liver disease in the Western world comprising a spectrum of liver damage from fatty liver infiltration to end-stage liver disease, in patients without significant alcohol consumption. Increased prevalence of NAFLD has been reported in patients with polycystic ovary syndrome (PCOS), one of the most common endocrinopathies in premenopausal women, which has been redefined as a reproductive and metabolic disorder after the recognition of the important role of insulin resistance in the pathophysiology of the syndrome. Obesity, in particular central adiposity and insulin resistance are considered as the main factors related to NAFLD in PCOS. Moreover, existing data support that androgen excess, which is the main feature of PCOS and is interrelated to insulin resistance, may be an additional contributing factor to the development of NAFLD. Although the natural history of NAFLD remains unclear and hepatic steatosis seems to be a relatively benign condition in most patients, limited data imply that advanced stage of liver disease is possibly more frequent in obese PCOS patients with NAFLD. PCOS patients, particularly obese patients with features of the metabolic syndrome, should be submitted to screening for NAFLD comprising assessment of serum aminotransferase levels and of hepatic steatosis by abdominal ultrasound. Lifestyle modifications including diet, weight loss and exercise are the most appropriate initial therapeutic interventions for PCOS patients with NAFLD. When pharmacologic therapy is considered, metformin may be used, although currently there is no medical therapy of proven benefit for NAFLD. Long-term follow up studies are needed to clarify clinical implications and guide appropriate diagnostic evaluation, follow-up protocol and optimal treatment for PCOS patients with NAFLD.

    Enthusiastic physicians and medical researchers are investigating the role of three-dimensional printing in medicine. The purpose of the current review is to provide a concise summary of the role of three-dimensional printing technology as it relates to the field of pediatric hepatology and liver transplantation. Our group and others have recently demonstrated the feasibility of printing three-dimensional livers with identical anatomical and geometrical landmarks to the native liver to facilitate presurgical planning of complex liver surgeries. Medical educators are exploring the use of three-dimensional printed organs in anatomy classes and surgical residencies. Moreover, mini-livers are being developed by regenerative medicine scientist as a way to test new drugs and, eventually, whole livers will be grown in the laboratory to replace organs with end-stage disease solving the organ shortage problem. From presurgical planning to medical education to ultimately the bioprinting of whole organs for transplantation, three-dimensional printing will change medicine as we know in the next few years.

    Liver transplantation has been remarkably effective in the treatment in patients with end-stage liver disease. However, disparity between solid-organ supply and increased demand is the greatest limitation, resulting in longer waiting times and increase in mortality of transplant recipients. This situation creates the need to seek alternatives to orthotopic liver transplantation.Hepatocyte transplantation or liver cell transplantation has been proposed as the best method to support patients. The procedure consists of transplanting individual cells to a recipient organ in sufficient quantity to survive and restore the function. The capacity of hepatic regeneration is the biological basis of hepatocyte transplantation. This therapeutic option is an experimental procedure in some patients with inborn errors of metabolism, fulminant hepatic failure and acute and chronic liver failure, as a bridge to orthotopic liver transplantation. In the Hospital La Fe of Valencia, we performed the first hepatocyte transplantation in Spain creating a new research work on transplant program. Copyright 2009 AEC. Published by Elsevier Espana.

    Aim: To describe and evaluate anatomical characterizations of incidental left atrial (LA) diverticula in patients with suspected coronary artery disease using 64-channel multidetector computed tomography (MDCT). Materials and methods: From October 2008 to June 2009, 2059 patients with suspected coronary artery disease underwent electrocardiogram-gated 64-channel MDCT. Five hundred and thirty-two LA diverticula were identified in 377 patients (18.3%, male to female ratio: 216:161, mean age 59 {+-} 10.89 years, range from 20 to 91 years). Two radiologists retrospectively analysed the number (single or multiple), size (diameter and length), shape (cystiform or tubiform), surface (smooth or irregular), and location (right or mid or left/upper or lower/lateral or posterior). If the length/diameter was <1.5, the diverticular shape was considered to be cystiform. Results: Among 532 LA diverticula, single (270/532, 51.1%), cystiform (411/532, 77.3%), and smooth (332/532, 62.4%) diverticula were found. The right upper region (255/532, 47.9%) was the most common location, followed by the left lateral area (172/532, 32.3%). The average diameter was 4.7 {+-} 2 mm (range from 1-19 mm), and the average length was 4.7 {+-} 2.1 mm (range 1-13 mm). The average ratio of length to diameter was 1.15 (range 0.25-1.45). The average number of diverticula was 2 {+-} 1.06 (range 1-5). Conclusion: Incidental LA diverticulum is not an uncommon finding in patients with suspected coronary artery disease. MDCT can provide anatomical details of LA diverticula. However, further studies are needed to determine their clinical significance.

    Nonalcoholic fatty liver disease (NAFLD) is a spectrum of chronic liver conditions that are characterized by steatosis, inflammation, fibrosis, and liver injury. The global prevalence of NAFLD is rapidly increasing in proportion to the rising incidence of obesity and type 2 diabetes. Because NAFLD is a multifaceted disorder with many underlying metabolic abnormalities, currently, there is no pharmacological agent that is therapeutically approved for the treatment of this disease. Folate is a water-soluble B vitamin that plays an essential role in one-carbon transfer reactions involved in nucleic acid biosynthesis, methylation reactions, and sulfur-containing amino acid metabolism. The liver is the primary organ responsible for storage and metabolism of folates. Low serum folate levels have been observed in patients with obesity and diabetes. It has been reported that a low level of endogenous folates in rodents perturbs folate-dependent one-carbon metabolism, and may be associated with development of metabolic diseases such as NAFLD. This review highlights the biological role of folate in the progression of NAFLD and its associated metabolic complications including obesity and type 2 diabetes. Understanding the role of folate in metabolic disease may position this vitamin as a potential therapeutic for NAFLD.

    When liver disease is severe, the prognosis can be worse if the patient is malnourished. Adequate nutritional support for patients with liver diseases can improve the patient's condition and prognosis. In the case of liver cirrhosis, malnutrition can occur due to a variety of causes, including poor oral intake, maldigestion, malabsorption, associated renal disease, and metabolic abnormalities. For a nutritional assessment, it is important to check the dietary intake, change in body composition, including anthropometry, and a functional assessment of muscle. Counselling and oral or enteral nutrition is preferred over parenteral nutrition as in other diseases. If esophageal varices are present, care should be taken when installing a feeding tube, but if there are ascites, percutaneous endoscopic gastrostomy is contraindicated because of the risk of complications. Calories of 30-35 kcal/kg/day and protein from 1.2 to 1.5 g/kg/day are appropriate. Protein restriction is unnecessary unless the hepatic encephalopathy is severe. A late evening snack and branched chain amino acids can be helpful. In the case of cholestasis, the supply of manganese and copper should be restricted. Sarcopenia in patients with liver cirrhosis is also prevalent and associated with the prognosis.

    Minimal encephalopathy was originally associated with chronic liver disease but is increasingly associated with most other chronic diseases and particularly with diabetes and also chronic disorders in other organs: kidneys, lungs, thyroid and with obesity. It is increasingly with dramatically increased and more or less permanent increase in systemic inflammation, most likely a result of Western lifestyle. Frequent physical exercise and intake of foods rich in vitamins, antioxidants, fibres, lactic acid bacteria etc in combination with reduction in intake of refined and processed foods is known to reduce systemic inflammation and prevent chronic diseases. Some lactic acid bacteria, especially Lb paracasei, lb plantarum and pediococcus pentosaceus have proven effective to reduce inflammation and eliminate encephalopathy. Significant reduction in blood ammonia levels and endotoxin levels were reported in parallel to improvement of liver disease. Subsequent studies with other lactic acid bacteria seem to demonstrate suppression of inflammation and one study also provides evidence of clinical improvement.

    Non-alcoholic fatty liver disease (NAFLD) encompasses the simple steatosis to more progressive steatosis with associated hepatitis, fibrosis, cirrhosis, and in some cases hepatocellular carcinoma. NAFLD is a growing epidemic, not only in the United States, but worldwide in part due to obesity and insulin resistance leading to liver accumulation of triglycerides and free fatty acids. Numerous risk factors for the development of NAFLD have been espoused with most having some form of metabolic derangement or insulin resistance at the core of its pathophysiology. NAFLD patients are at increased risk of liver-related as well as cardiovascular mortality, and NAFLD is rapidly becoming the leading indication for liver transplantation. Liver biopsy remains the gold standard for definitive diagnosis, but the development of noninvasive advanced imaging, biochemical and genetic tests will no doubt provide future clinicians with a great deal of information and opportunity for enhanced understanding of the pathogenesis and targeted treatment. As it currently stands several medications/supplements are being used in the treatment of NAFLD; however, none seem to be the “magic bullet” in curtailing this growing problem yet. In this review we summarized the current knowledge of NAFLD epidemiology, risk factors, diagnosis, pathogenesis, pathologic changes, natural history, and treatment in order to aid in further understanding this disease and better managing NAFLD patients.

  12. Metabolic Disturbances in Children with Chronic Liver Disease

    2014-04-01

    Full Text Available Introduction: Liver disease results in complex pathophysiologic disturbances affecting nutrient digestion, absorption, distribution, storage, and use. This article aimed to present a classification of metabolic disturbances in chronic liver disease in children?   Materials and Methods: In this review study databases including proquest, pubmedcentral, scincedirect, ovid, medlineplus were been searched with keyword words such as” chronic liver disease"  ” metabolic disorder””children” between 1999 to 2014. Finally, 8 related articles have been found.   Results: Metabolic disorder in this population could be categorized in four set: 1carbohydrates, 2proteins,3 fats and 4vitamins. 1 Carbohydrates: Children with CLD are at increased risk for fasting hypoglycemia, because the capacity for glycogen storage and gluconeogenesis is reduced as a result of abnormal hepatocyte function and loss of hepatocyte mass. 2 Proteins: The liver’s capacity for plasma protein synthesis is impaired by reduced substrate availability, impaired hepatocyte function, and increased catabolism. This results in hypoalbuminemia, leading to peripheral edema and contributing to ascites. Reduced synthesis of insulin-like growth factor (IGF-1 and its binding protein IGF-BP3 by the chronically diseased liver results in growth hormone resistance and may contribute to the poor growth observed in these children. 3 Fats: There is increased fat oxidation in children with end-stage liver disease in the fed and fasting states compared with controls, which is probably related to reduced carbohydrate availability. The increased lipolysis results in a decrease in fat stores, which may not be easily replenished in the setting of the fat malabsorption that accompanies cholestasis. Reduced bile delivery to the gut results in impaired fat emulsification, and hence digestion. The products of fat digestion are also poorly absorbed, because bile is also required for micelle formation

    Full Text Available Non-alcoholic fatty liver disease is an increasing health issue that develops rather unnoticed with obesity, type 2 diabetes mellitus and metabolic syndrome. We investigated prevalence, determinants and associated metabolic abnormalities of non-alcoholic fatty liver disease in the largest population-based cohort to date.Biochemical characteristics, type 2 diabetes mellitus and metabolic syndrome were determined in the Lifelines Cohort Study (N = 167,729, a population-based cohort in the North of the Netherlands. Non-alcoholic fatty liver disease was defined as Fatty Liver Index (FLI≥60. Exclusion criteria were age <18 years, immigrants, missing data to assess FLI and metabolic syndrome, excessive alcohol use, previous-diagnosed hepatitis or cirrhosis and non-fasting blood sampling.Out of 37,496 included participants (median age 44 years, 62.1% female, 8,259 (22.0% had a FLI≥60.

    Highlights: • FXR, PGC1α and PPARγ levels are upregulated in NHE1 deficient livers. • NHE1 deficiency downregulates expression of pro-lipogenic genes in liver. • Chronic exposure to high-fat diet upregulates hepatic NHE1 expression. • Loss of NHE1 better preserves hepatic insulin signaling in high-fat diet-fed mice. - Abstract: Non-alcoholic fatty liver disease NAFLD is closely associated with the dysregulation of lipid homeostasis. Diet-induced hepatic steatosis, which can initiate NAFLD progression, has been shown to be dramatically reduced in mice lacking the electroneutral Na{sup +}/H{sup +} exchanger NHE1 (Slc9a1). In this study, we investigated if NHE1 deficiency had effects in liver that could contribute to the apparent protection against aberrant lipid accumulation. RT-PCR and immunoblot analyses of wild-type and NHE1-null livers revealed an expression profile that strongly suggested attenuation of both de novo lipogenesis and hepatic stellate cell activation, which is implicated in liver fibrosis. This included upregulation of the farnesoid X receptor FXR, peroxisome proliferator-activated receptor PPARγ, its co-activator PGC1α, and sestrin 2, an antioxidant protein involved in hepatic metabolic homeostasis. Furthermore, expression levels of the pro-lipogenic liver X receptor LXRα, and acetyl CoA carboxylases 1 and 2 were downregulated. These changes were associated with evidence of reduced cellular stress, which persisted even upon exposure to a high-fat diet, and the better preservation of insulin signaling, as evidenced by protein kinase B/Akt phosphorylation (Ser473). These results indicate that NHE1 deficiency may protect against NAFLD pathogenesis, which is significant given the availability of highly specific NHE1 inhibitors.

    Nonalcoholic fatty liver disease (NAFLD) is characterized by accumulation of fat within the Liver. The main objective of this work is (1) to evaluate the feasibility of measuring in vivo in the liver the shear wave phase velocity dispersion cs(ω) between 20 Hz and 90 Hz using vibration-controlled transient elastography (VCTE); (2) to estimate through the rheological Kelvin-Voigt model the shear elastic μ and shear viscosity η modulus; (3) to correlate the evolution of these viscoelastic parameters on two patients at Tours Hospital with the hepatic fat percentage measured with T1-weighted gradient-echo in-and out-phase MRI sequence. For the first volunteer who has 2% of fat in the liver, we obtained μ = 1233 ± 133 Pa and η = 0.5 ± 0.4 Pa.s. For the patient with 22% of fat, we measure μ = 964 ± 91 Pa and η = 1.77 ± 0.3 Pa.s. In conclusion, this novel method showed to be sensitive in characterizing the visco-elastic properties of fatty liver.

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

    Full Text Available Nonalcoholic fatty liver disease (NAFLD is the most common chronic liver disease in the Western world (it affects 30% of the general adult population. The NAFLD encompasses a histological spectrum ranging from simple steatosis to nonalcoholic steatohepatitis (NASH, defined by steatosis, hepatocellular damage, and lobular inflammation in individuals without significant alcohol consumption and negative viral, congenital, and autoimmune liver disease markers. Currently, NAFLD is considered an emerging epidemic in light of the dramatic increase in obesity rates. With the progressive nature of NASH and its rising prevalence there is a significant need for a specific and targeted treatments since to date there has not been any validated therapies for NAFLD other than weight loss, which is well known to have a poor long-term success rate. In recent years, visceral adipose tissue has taken an important role in NAFLD pathogenesis, and current therapeutic approaches aim at reducing visceral obesity and free fatty acid overflow to the liver. This paper is focused on the treatments used for NAFLD and the potential new therapy.

  2. NK Cell Subtypes as Regulators of Autoimmune Liver Disease

    Directory of Open Access Journals (Sweden)

    2016-01-01

    Full Text Available As major components of innate immunity, NK cells not only exert cell-mediated cytotoxicity to destroy tumors or infected cells, but also act to regulate the functions of other cells in the immune system by secreting cytokines and chemokines. Thus, NK cells provide surveillance in the early defense against viruses, intracellular bacteria, and cancer cells. However, the effecter function of NK cells must be exquisitely controlled to prevent inadvertent attack against normal “self” cells. In an organ such as the liver, where the distinction between immunotolerance and immune defense against routinely processed pathogens is critical, the plethora of NK cells has a unique role in the maintenance of homeostasis. Once self-tolerance is broken, autoimmune liver disease resulted. NK cells act as a “two-edged weapon” and even play opposite roles with both regulatory and inducer activities in the hepatic environment. That is, NK cells act not only to produce inflammatory cytokines and chemokines, but also to alter the proliferation and activation of associated lymphocytes. However, the precise regulatory mechanisms at work in autoimmune liver diseases remain to be identified. In this review, we focus on recent research with NK cells and their potential role in the development of autoimmune liver disease.

    Full Text Available Angiogenesis is believed to be implicated in the pathogenesis of alcoholic liver disease (ALD. We aimed to explore the usefulness and accuracy of plasma angiogenic biomarkers for noninvasive evaluation of the severity of liver failure and ALD outcome. One hundred and forty-seven patients with ALD were prospectively enrolled and assessed based on their (1 gender, (2 age, (3 severity of liver dysfunction according to the Child-Turcotte-Pugh and MELD scores, and (4 the presence of ALD complications. Plasma levels of vascular endothelial growth factor (VEGF-A and angiopoietins 1 and 2 (Ang1 and Ang2 were investigated using ELISAs. Multivariable logistic regression was applied in order to select independent predictors of advanced liver dysfunction and the disease complications. Significantly higher concentrations of Ang2 and VEGF-A in ALD patients as compared to controls were found. There was no difference in Ang1 levels in both groups. A positive correlation of Ang2 levels with INR (Rho 0.66; P<0.0001 and its inverse correlation with plasma albumin levels (Rho –0.62; P<0.0001 were found. High Ang2 concentrations turned out to be an independent predictor of severe liver dysfunction, as well as hepatic encephalopathy and renal impairment. Ang2 possessed the highest diagnostic and prognostic potential among three studied angiogenesis-related molecules.

    Full Text Available Despite extensive research, alcohol remains one of the most common causes of liver disease in the United States. Alcoholic liver disease (ALD encompasses a broad spectrum of disorders, including steatosis, steatohepatitis, and cirrhosis. Although many agents and approaches have been tested in patients with ALD and in animals with experimental ALD in the past, there is still no FDA (Food and Drug Administration approved therapy for any stage of ALD. With the increasing recognition of the importance of gut microbiota in the onset and development of a variety of diseases, the potential use of probiotics in ALD is receiving increasing investigative and clinical attention. In this review, we summarize recent studies on probiotic intervention in the prevention and treatment of ALD in experimental animal models and patients. Potential mechanisms underlying the probiotic function are also discussed.

If the disease is caused by an obstructed vessel, this is reliably detected. For most types of thesaurismosis as well as hepatic steatosis and cirrhosis of the liver approaches to quantitative determinations of the spread of disease have been described in theory but so far failed to show great merits in practice. The transition from hepatic fibrosis to cirrhosis as the final developmental stage common to all those disorders has typical features on computerized tomography. This explains why the use of this method in diffuse hepatic disease offers particular advantages as regards the detection of complications occurring at an advanced stage ot the diagnosis of changes developing into malignancies.

    Full Text Available Nonalcoholic fatty liver disease (NAFLD is the most common liver disease worldwide and it is associated with other medical conditions such as diabetes mellitus, metabolic syndrome, and obesity. The mechanisms of the underlying disease development and progression are not completely established and there is no consensus concerning the pharmacological treatment. In the gold standard treatment for NAFLD weight loss, dietary therapy, and physical activity are included. However, little scientific evidence is available on diet and/or physical activity and NAFLD specifically. Many dietary approaches such as Mediterranean and DASH diet are used for treatment of other cardiometabolic risk factors such as insulin resistance and type-2 diabetes mellitus (T2DM, but on the basis of its components their role in NAFLD has been discussed. In this review, the implications of current dietary and exercise approaches, including Brazilian and other guidelines, are discussed, with a focus on determining the optimal nonpharmacological treatment to prescribe for NAFLD.

    Studied was the relation of the subclinical, recurring, and chronic rumen acidosis, on the one hand, to the disturbed function, resp., injuries of the liver, on the other. Experiments were carried out with a total of 862 high-producing cows, 54 out of which had massive injuries of the liver. Full clinical examination was performed, 22 of the animals being subject to laboratory investigations with regard to the rumen content (pH, infusorial count per 1 cm3 with the differentiation of bacteria, activity with regard to glucose, nitrates, sedimentation, and flotation), blood (whole blood picture, coagulation tests, bilirubin, SGOT, SGPT, serum aldolase, alkaline phosphatase, alkaline reserves, blood sugar), and urine (pH, protein, ketone bodies, sugar, and CSR). It is concluded that three inferences could be drawn, pointing to the relation between recurring rumen acidosis and the liver diseases.

    The effectiveness of technetium /sup 99m/-labeled diethylenetriaminepentaacetic acid (/sup 99m/Tc DTPA) to assess renal function in 13 dogs with suspected renal disease was evaluated. Glomerular filtration rates (actual GFR) were determined on the basis of endogenous creatinine clearance. Predicted GFR were determined by using /sup 99m/Tc DTPA within 72 hours after the determination of creatinine clearance. The percentage of an IV administered dose of /sup 99m/Tc DTPA in the kidneys (percentage dose) was determined. Two equations were used to calculate predicted GFR, which were derived from previously reported linear regression analysis of inulin (In) and creatinine (Cr) GFR vs percentage dose /sup 99m/Tc DTPA in dog kidneys. The correlations of actual GFR vs predicted GFR (In) and actual GFR vs predicted GFR (Cr) were both r = 0.92. The dogs' mean actual GFR was 1.73 +/- 1.35 ml/min/kg. Their mean predicted GFR (In) and predicted GFR (Cr) were 1.92 +/- 1.42 ml/min/kg and 1.85 +/- 1.27 ml/min/kg, respectively. Therefore, /sup 99m/Tc DTPA can be used with high accuracy as an agent to predict GFR in dogs with suspected renal disease. The procedure for determining GFR by use of nuclear medicine was rapid and noninvasive and appeared to induce little stress in the animals evaluated

  10. Lipocalin-2 in Fructose-Induced Fatty Liver Disease

    Full Text Available The intake of excess dietary fructose most often leads to non-alcoholic fatty liver disease (NAFLD. Fructose is metabolized mainly in the liver and its chronic consumption results in lipogenic gene expression in this organ. However, precisely how fructose is involved in NAFLD progression is still not fully understood, limiting therapy. Lipocalin-2 (LCN2 is a small secreted transport protein that binds to fatty acids, phospholipids, steroids, retinol, and pheromones. LCN2 regulates lipid and energy metabolism in obesity and is upregulated in response to insulin. We previously discovered that LCN2 has a hepatoprotective effect during hepatic insult, and that its upregulation is a marker of liver damage and inflammation. To investigate if LCN2 has impact on the metabolism of fructose and thereby arising liver damage, we fed wild type and Lcn2−/− mice for 4 or 8 weeks on diets that were enriched in fructose either by adding this sugar to the drinking water (30% w/v, or by feeding a chow containing 60% (w/w fructose. Body weight and daily intake of food and water of these mice was then measured. Fat content in liver sections was visualized using Oil Red O stain, and expression levels of genes involved in fat and sugar metabolism were measured by qRT-PCR and Western blot analysis. We found that fructose-induced steatosis and liver damage was more prominent in female than in male mice, but that the most severe hepatic damage occurred in female mice lacking LCN2. Unexpectedly, consumption of elevated fructose did not induce de novo lipogenesis or fat accumulation. We conclude that LCN2 acts in a lipid-independent manner to protect the liver against fructose-induced damage.

  11. Non-alcoholic Fatty Liver Disease: Beneficial Effects of Flavonoids.

    Non-alcoholic fatty liver disease (NAFLD) has been known as the hepatic feature of metabolic syndrome. Extra fat depots, especially in visceral areas, develop insulin resistance as a result of mild oxidation and inflammation. Insulin resistance induces lipolysis and releases free fatty acids into the circulation, where they are transported to the liver. In the liver, free fatty acids are converted to triglycerides and accumulate, causing simple steatosis that, if left untreated, can lead to steatohepatitis, and subsequently liver necrosis and cirrhosis.Flavonoids, a group of plant compounds with incredible biological characteristics, have shown advantages in pathological conditions. Beneficial effects of flavonoids against NAFLD and its related disorders have been observed in both animal and human studies. Various mechanisms have been found for their protection. Flavonoids prevent hepatosteatosis by increasing fatty acid oxidation in the liver. They can also reduce caloric intake and decrease body weight and fat deposition in visceral tissues. Flavonoids are unique antioxidants that exert their beneficial effects through inhibition of nuclear factor κB, thereby attenuating release of inflammatory cytokines, which are triggers of insulin resistance. Finally, flavonoids have shown to increase adiponectin, improve insulin sensitivity and glucose tolerance, correct dyslipidemia, and reduce blood pressure in patients with NAFLD.

    Full Text Available Liver metastasis in solid tumors, including colorectal cancer, is the most frequent and lethal complication. The development of systemic therapy has led to prolonged survival. However, in selected patients with a finite number of discrete lesions in liver, defined as oligometastatic state, additional local therapies such as surgical resection, radiofrequency ablation, cryotherapy, and radiotherapy can lead to permanent local disease control and improve survival. Among these, an advance in radiation therapy made it possible to deliver high dose radiation to the tumor more accurately, without impairing the liver function. In recent years, the introduction of stereotactic ablative radiotherapy (SABR has offered even more intensive tumor dose escalation in a few fractions with reduced dose to the adjacent normal liver. Many studies have shown that SABR for oligometastases is effective and safe, with local control rates widely ranging from 50% to 100% at one or two years. And actuarial survival at one and two years has been reported ranging from 72% to 94% and from 30% to 62%, respectively, without severe toxicities. In this paper, we described the definition and technical aspects of SABR, clinical outcomes including efficacy and toxicity, and related parameters after SABR in liver oligometastases from colorectal cancer.

    The prevalence of obesity and related morbidities such as nonalcoholic fatty liver disease (NAFLD) is high among adolescents. Current treatment recommendations for NAFLD focus on lifestyle optimization via nutrition and exercise. After encouraging exercise, many adolescents choose to participate in organized sports, which may lead to use of illicit substances such as anabolic androgenic steroids (AAS) to boost athletic performance. Approximately 3,000,000 individuals use non-therapeutic AAS at supra-physiologic doses in the United States.1 In 2012, 5.9% of adolescent boys reported steroid use in the previous year.2 We anticipate adolescents with pre-existing liver disease are at increased risk for AAS induced hepatotoxicity. We present such a case with IRB approval and written individual patient consent. PMID:23568051

     Many people with celiac disease are undiagnosed and there is evidence that insufficient duodenal samples may contribute to underdiagnosis. The aims of this study were to investigate whether more samples leads to a greater likelihood of a diagnosis of celiac disease and to elucidate factors that influence the number of samples collected.  We identified patients from two community hospitals who were undergoing duodenal biopsy for indications (as identified by International Classification of Diseases code) compatible with possible celiac disease. Three cohorts were evaluated: no celiac disease (NCD, normal villi), celiac disease (villous atrophy, Marsh score 3), and possible celiac disease (PCD, Marsh score celiac disease had a median of 4 specimens collected. The percentage of patients diagnosed with celiac disease with one sample was 0.3 % compared with 12.8 % of those with six samples ( P  = 0.001). Patient factors that positively correlated with the number of samples collected were endoscopic features, demographic details, and indication ( P  = 0.001). Endoscopist factors that positively correlated with the number of samples collected were absence of a trainee, pediatric gastroenterologist, and outpatient setting ( P  celiac disease significantly increased with six samples. Multiple factors influenced whether adequate biopsies were taken. Adherence to guidelines may increase the diagnosis rate of celiac disease.

    Abnormal biliary secretion leads to the thickening of bile and the formation of plugs within the bile ducts; the consequent obstruction and abnormal bile flow ultimately results in the development of cystic fibrosis-related liver disease. This condition peaks in adolescence with up to 20% of adolescents with cystic fibrosis developing chronic liver disease. Early changes in the liver may ultimately result in end-stage liver disease with people needing transplantation. One therapeutic option currently used is ursodeoxycholic acid. This is an update of a previous review. To analyse evidence that ursodeoxycholic acid improves indices of liver function, reduces the risk of developing chronic liver disease and improves outcomes in general in cystic fibrosis. We searched the Cochrane CF and Genetic Disorders Group Trials Register comprising references identified from comprehensive electronic database searches, handsearches of relevant journals and abstract books of conference proceedings. We also contacted drug companies and searched online trial registries.Date of the most recent search of the Group's trials register: 09 April 2017. Randomised controlled trials of the use of ursodeoxycholic acid for at least three months compared with placebo or no additional treatment in people with cystic fibrosis. Two authors independently assessed trial eligibility and quality. The authors used GRADE to assess the quality of the evidence. Twelve trials have been identified, of which four trials involving 137 participants were included; data were only available from three of the trials (118 participants) since one cross-over trial did not report appropriate data. The dose of ursodeoxycholic acid ranged from 10 to 20 mg/kg/day for up to 12 months. The complex design used in two trials meant that data could only be analysed for subsets of participants. There was no significant difference in weight change, mean difference -0.90 kg (95% confidence interval -1.94 to 0.14) based on 30

    Non-alcoholic fatty liver disease (NAFLD) is a chronic liver disease that might affect up to one-third of the adult population in industrialised countries. NAFLD incorporates histologically and clinically different non-alcoholic entities; fatty liver (NAFL, steatosis hepatis) and steatohepatitis (NASH-characterised by hepatocyte ballooning and lobular inflammation ± fibrosis) might progress to cirrhosis and rarely to hepatocellular cancer. NAFL increasingly affects children (paediatric prevalence is 4.2%-9.6%). Type 2 diabetes mellitus (T2DM), insulin resistance (IR), obesity, metabolic syndrome and NAFLD are particularly closely related. Increased hepatic lipid storage is an early abnormality in insulin resistant women with a history of gestational diabetes mellitus. The accumulation of triacylglycerols in hepatocytes is predominantly derived from the plasma nonesterified fatty acid pool supplied largely by the adipose tissue. A few NAFLD susceptibility gene variants are associated with progressive liver disease, IR, T2DM and a higher risk for hepatocellular carcinoma. Although not approved, pharmacological approaches might be considered in NASH patients.

    Full Text Available Berberine (BBR, an active ingredient from nature plants, has demonstrated multiple biological activities and pharmacological effects in a series of metabolic diseases including nonalcoholic fatty liver disease (NAFLD. The recent literature points out that BBR may be a potential drug for NAFLD in both experimental models and clinical trials. This review highlights important discoveries of BBR in this increasing disease and addresses the relevant targets of BBR on NAFLD which links to insulin pathway, adenosine monophosphate-activated protein kinase (AMPK signaling, gut environment, hepatic lipid transportation, among others. Developing nuanced understanding of the mechanisms will help to optimize more targeted and effective clinical application of BBR for NAFLD.

    Full Text Available Hepatocyte differentiation, proliferation, and apoptosis are affected by growth factors produced in liver. Insulin-like growth factor 1 and 2 (IGF1 and IGF2 act in response to growth hormone (GH. Other IGF family components include at least six binding proteins (IGFBP1 to 6, manifested by both IGFs develop due to interaction through the type 1 receptor (IGF1R. The data based on animal models and/or in vitro studies suggest the role of IGF system components in cellular aspects of hepatocarcinogenesis (cell cycle progression, uncontrolled proliferation, cell survival, migration, inhibition of apoptosis, protein synthesis and cell growth, and show that systemic IGF1 administration can reduce fibrosis and ameliorate general liver function. In epidemiologic and clinicopathological studies on chronic liver disease (CLD, lowered serum levels, decreased tissue expression of IGF1, elevated production of IGF1R and variable IGF2 expression has been noted, from the start of preneoplastic alterations up to the developed hepatocellular carcinoma (HCC stage. These changes result in well-known clinical symptoms of IGF1 deficiency. This review summarized the current data of the complex role of IGF system components in the most common CLD (nonalcoholic fatty liver disease, cirrhosis, and hepatocellular carcinoma. Better recognition and understanding of this system can contribute to discovery of new and improved versions of current preventive and therapeutic actions in CLD.

    Coffee intake is associated with reduced risk of liver cancer and chronic liver disease as reported in previous studies, including prospective ones conducted in Asian populations where hepatitis B viruses (HBVs) and hepatitis C viruses (HCVs) are the dominant risk factors. Yet, prospective studies in Western populations with lower HBV and HCV prevalence are sparse. Also, although preparation methods affect coffee constituents, it is unknown whether different methods affect disease associations. We evaluated the association of coffee intake with incident liver cancer and chronic liver disease mortality in 27,037 Finnish male smokers, aged 50-69, in the Alpha-Tocopherol, Beta-Carotene Cancer Prevention Study, who recorded their coffee consumption and were followed up to 24 years for incident liver cancer or chronic liver disease mortality. Multivariate relative risks (RRs) and 95% confidence intervals (CIs) were estimated by Cox proportional hazard models. Coffee intake was inversely associated with incident liver cancer (RR per cup per day=0.82, 95% CI: 0.73-0.93; P-trend across categories=0.0007) and mortality from chronic liver disease (RR=0.55, 95% CI: 0.48-0.63; P-trendcoffee. These findings suggest that drinking coffee may have benefits for the liver, irrespective of whether coffee was boiled or filtered.

    A gluten-free diet is the only recommended treatment for coeliac disease. To determine the prevalence and characteristics of reactions to gluten among persons with coeliac disease on a gluten-free diet. Adults with biopsy proven, newly diagnosed coeliac disease were prospectively enrolled. A survey related to diet adherence and reactions to gluten was completed at study entry and 6 months. The Coeliac Symptom Index, Coeliac Diet Assessment Tool (CDAT) and Gluten-Free Eating Assessment Tool (GF-EAT) were used to measure coeliac disease symptoms and gluten-free diet adherence. Of the 105 participants, 91% reported gluten exposure gluten was reported by 66%. Gluten consumption was unsuspected until a reaction occurred (63%) or resulted from problems ordering in a restaurant (29%). The amount of gluten consumed ranged from cross-contact (30%) to a major ingredient (10%). Median time to symptom onset was 1 h (range 10 min to 48 h), and median symptom duration was 24 h (range 1 h to 8 days). Common symptoms included abdominal pain (80%), diarrhoea (52%), fatigue (33%), headache (30%) and irritability (29%). Reactions to suspected gluten exposure are common among patients with coeliac disease on a gluten-free diet. Eating at restaurants and other peoples' homes remain a risk for unintentional gluten exposure. When following individuals with coeliac disease, clinicians should include questions regarding reactions to gluten as part of their assessment of gluten-free diet adherence. © 2016 John Wiley & Sons Ltd.

    Chronic subdural hematoma (cSDH) is a common neurosurgical ailment, particularly in elderly patients. A recent study uncovered an association between liver disease and recurrence in patients with cSDH. Here, we explored that relationship to identify recurrence predictors in at-risk patients. We hypothesized that the association between liver disease and recurrence was attributable to coagulopathy secondary to liver disease. We retrospectively reviewed all patients with cSDH treated with burr-hole drainage by 2 surgeons between 2007 and 2015. Comorbidities and laboratory findings for each patient were examined by Pearson χ 2 analysis or Mann-Whitney U tests. We identified 261 cSDH in 215 patients. Patients were a mean age of 65.6 years, and 72% were male. Sixteen patients with cSDH required repeat surgery (6.1%). There were 123 coagulopathic patients (47.1%), and 14 with liver disease (5.4%), all of whom were coagulopathic (P < 0.001). Coagulopathic patients with liver disease were more likely to experience recurrence than patients with coagulopathy alone (relative risk = 4.09, P = 0.019). Patients with liver disease had significantly elevated prothrombin time (P = 0.013) and reduced platelet counts (P < 0.001). Platelets also were reduced in coagulopathic patients with liver disease, as compared with those with coagulopathy alone (P = 0.002). Thrombocytopenia remained significant in a multivariate analysis (P < 0.001). Liver disease is significantly associated with the recurrence of cSDH. Although coagulopathy alone does not predict recurrence, patients with coagulopathy and liver disease are at greater risk for recurrence than those with coagulopathy alone. Liver disease effects are reflected in certain hematologic laboratory values. Copyright © 2017 Elsevier Inc. All rights reserved.

    Statistical parametric mapping (SPM) gained increasing acceptance for the voxel-based statistical evaluation of brain positron emission tomography (PET) with the glucose analog 2-[18F]-fluoro-2-deoxy-d-glucose (FDG) in patients with suspected Alzheimer's disease (AD). To increase the sensitivity for detection of local changes, individual differences of total brain FDG uptake are usually compensated for by proportional scaling. However, in cases of extensive hypometabolic areas, proportional scaling overestimates scaled uptake. This may cause significant underestimation of the extent of hypometabolic areas by the statistical test. To detect this problem, the authors tested for hypermetabolism. In patients with no visual evidence of true focal hypermetabolism, significant clusters of hypermetabolism in the presence of extended hypometabolism were interpreted as false-positive findings, indicating relevant overestimation of scaled uptake. In this case, scaled uptake was reduced step by step until there were no more significant clusters of hypermetabolism. In 22 consecutive patients with suspected AD, proportional scaling resulted in relevant overestimation of scaled uptake in 9 patients. Scaled uptake had to be reduced by 11.1% +/- 5.3% in these cases to eliminate the artifacts. Adjusted scaling resulted in extension of existing and appearance of new clusters of hypometabolism. Total volume of the additional voxels with significant hypometabolism depended linearly on the extent of the additional scaling and was 202 +/- 118 mL on average. Adjusted scaling helps to identify characteristic metabolic patterns in patients with suspected AD. It is expected to increase specificity of FDGPET in this group of patients.

    Coronary artery calcium (CAC) can be used to estimate vascular age in adults, providing a convenient transformation of CAC from Agatston units into a year's scale. We investigated the role of coronary vascular age in predicting stress-induced myocardial ischemia in subjects with suspected coronary artery disease (CAD). A total of 717 subjects referred to CAC scoring and 82 Rb PET/CT stress-rest myocardial perfusion imaging for suspected CAD were studied. CAC score was measured according to the Agatston method and coronary vascular age by equating estimated CAD risk for chronological age and CAC using the formula 39.1 + 7.25 × ln(CAC + 1). Stress-induced ischemia was present in 105 (15%) patients. Mean chronological age, CAC score, and coronary vascular age were higher (all P age was added to clinical variables. Including vascular age in the model, the global Chi square further increased from 68.77 to 106.38 (P age to clinical data, continuous net reclassification improvement (cNRI) was 0.57, while adding vascular age to clinical data and chronological age cNRI was 0.62. At decision curve analysis, the model including vascular age was associated with the highest net benefit compared to the model including only clinical data, to the model including chronological age and clinical data, and to a strategy considering that all patients had ischemia. The model including vascular age also showed the largest reduction in false-positive rate without missing any ischemic patients. In subjects with suspected CAD, coronary vascular age is strongly associated with stress-induced ischemia. The communication of a given vascular age would have a superior emotive impact improving observance of therapies and healthier lifestyles.

    Full Text Available BACKGROUND: Nonalcoholic fatty liver disease (NAFLD and gallstone disease (GD are both highly prevalent in the general population and associated with obesity and insulin resistance. We aimed to evaluate the prevalence of GD in a cross sectional study of NAFLD patients and to define whether the presence of GD is associated with diabetes and predicts more severe liver disease. METHODOLOGY/PRINCIPAL FINDINGS: We merged databases of four Liver Units, comprising 524 consecutive biopsy-proven NAFLD (373 males observed between January 2003 and June 2010. GD was diagnosed in 108 (20%, and 313 cases (60% were classified by liver biopsy as nonalcoholic steatohepatitis (NASH. The GD subgroup was characterized by a significantly higher prevalence of females, prediabetes/diabetes, abdominal obesity and metabolic syndrome, older age, higher BMI, fasting glucose, HOMA-IR and lower ALT. The prevalence of GD progressively increased with advancing fibrosis and with the severity of necroinflammatory activity (p for trend  = 0.0001 and  = 0.01, respectively, without differences in the severity of steatosis. At multivariate analysis GD was associated with female gender (OR 1.37, 95% CI 1.04-1.8, age (OR 1.027, 95% CI1.003-1.05, fasting glucose (OR 1.21, 95% CI 1.10-1.33 and NASH (OR 1.40,95% CI 1.06-1.89, whereas ALT levels were associated with a lower GD risk (OR 0.98, 95% CI 0.97-0.99. When subjects with cirrhosis were excluded from analysis, the association between GD and fasting glucose, female gender, and NASH was maintained. CONCLUSION: Patients with NAFLD have a high prevalence of GD, which characterizes subjects with altered glucose regulation and more advanced liver disease.

    Acute encephalopathy in a patient with alcoholic liver disease (ALD) is a commonly encountered emergency situation occurring most frequently due to liver failure precipitated by varying etiologies. Acute reversible cerebellar ataxia with confusion secondary to prolonged metronidazole use has been reported rarely as a cause of encephalopathy in patients with ALD. We describe a decompensated ALD patient with recurrent pyogenic cholangitis associated with hepatolithiasis who presented to the emergency department with sudden-onset cerebellar ataxia with dysarthria and mental confusion after prolonged use of metronidazole. Magnetic resonance imaging (MRI) of the brain was suggestive of bilateral dentate nuclei hyper intensities on T2 and fluid-attenuated inversion recovery sections seen classically in metronidazole-induced encephalopathy (MIE). Decompensated liver cirrhosis resulted in decreased hepatic clearance and increased cerebrospinal fluid concentration of metronidazole leading to toxicity at a relatively low total cumulative dose of 22 g. Both the clinical symptoms and MRI brain changes were reversed at 7 days and 6 weeks, respectively, after discontinuation of metronidazole. WHY SHOULD AN EMERGENCY PHYSICIAN BE AWARE OF THIS?: A patient with ALD presenting with encephalopathy creates a diagnostic dilemma for the emergency physician regarding whether to continue metronidazole and treat for hepatic encephalopathy or to suspect for MIE and withhold the drug. Failure to timely discontinue metronidazole may worsen the associated hepatic encephalopathy in these patients. Liver cirrhosis patients have higher mean concentration of metronidazole and its metabolite in the blood, making it necessary to keep the cumulative dose of metronidazole to < 20 g in them.

    Retinoic acid (RA), an active metabolite of vitamin A (retinol), has been implicated in the regulation of lipid metabolism and hepatic steatosis in animal models. However, the relation between RA and liver histology in patients with nonalcoholic fatty liver disease (NAFLD) and nonalcoholic steatohepatitis (NASH) is unknown. This study aimed at examining the association of RA with NAFLD and NASH in Chinese subjects. Serum RA concentration was determined by ELISA in 41 control subjects, 45 patients with NAFLD, and 38 patients with NASH. The associations of RA with adiposity, serum glucose, lipid profiles, and markers of liver damage were studied. Moreover, both mRNA and protein levels of retinoic X receptor α (RXRα) in the liver were analyzed in subjects with different degrees of hepatic steatosis. Serum RA concentrations in patients with NAFLD (1.42 ± 0.47 ng/mL) and NASH (1.14 ± 0.26 ng/mL) were significantly lower than those in control subjects (2.70 ± 0.52 ng/mL) (P hepatic steatosis. Both serum RA concentrations and RXRα mRNA levels were inversely correlated with intrahepatic triglyceride content (r = -0.700, P hepatic lipid metabolism and insulin resistance.

    BACKGROUND: Excessive alcohol use has been implicated as a risk factor in the development of psoriasis, particularly in men. Despite this, little is known of the incidence or prevalence of psoriasis in patients who misuse alcohol. OBJECTIVE: To assess the prevalence of psoriasis in patients with alcoholic liver disease. METHODS: In total, 100 patients with proven alcoholic liver disease were surveyed for a history of psoriasis and a full skin examination was performed if relevant. RESULTS: Of the 100 patients, 15 reported a history of psoriasis and another 8 had evidence of current activity, suggesting a prevalence (past or present) of 15% in this group of patients. CONCLUSION: It would appear that the prevalence of psoriasis in patients who misuse alcohol is much higher than the 1-3% variously quoted in the general population.

    Parenteral nutrition-associated liver disease (PNALD) is a particularly important problem in patients who need this type of nutritional support for a long time. Prevalence of the condition is highly variable depending on the series, and its clinical presentation is different in adults and children. The etiology of PNALD is not well defined, and participation of several factors at the same time has been suggested. When a bilirubin level >2 mg/dl is detected for a long time, other causes of liver disease should be ruled out and risk factors should be minimized. The composition of lipid emulsions used in parenteral nutrition is one of the factors related to PNALD. This article reviews the different types of lipid emulsions and the potential benefits of emulsions enriched with omega-3 fatty acids. Copyright © 2014 SEEN. Published by Elsevier España, S.L.U.

    2016-01-01

    Non-alcoholic fatty liver disease (NAFLD) is the most common form of chronic liver disease and its incidence is increasing worldwide. However, the underlying mechanisms leading to the development of NAFLD are still not fully understood. Glycosyltransferases (GTs) are a diverse class of enzymes involved in catalyzing the transfer of one or multiple sugar residues to a wide range of acceptor molecules. GTs mediate a wide range of functions from structure and storage to signaling, and play a key role in many fundamental biological processes. Therefore, it is anticipated that GTs have a role in the pathogenesis of NAFLD. In this article, we present an overview of the basic information on NAFLD, particularly GTs and glycosylation modification of certain molecules and their association with NAFLD pathogenesis. In addition, the effects and mechanisms of some GTs in the development of NAFLD are summarized. PMID:26937136

    The metabolic changes compounded by anorexia associated with chronic liver disease adversely affect growth in children. In many cases, this requires the administration of artificial nutritional support. It is important in this group of patients that those who are becoming nutritionally depleted are identified quickly and in those receiving artificial nutritional support, the effectiveness is monitored. The current review is an examination of methods available to assess nutritional status. These include anthropometry, methods available in the laboratory and a selection of less commonly used methods undergoing evaluation at research level. A brief discussion accompanies each technique, outlining the limitations of its use in children with chronic liver disease. The review concludes with an outline of how nutritional status should be assessed in this group of children, and suggests further research.

    2017-07-01

    Full Text Available Accumulating evidence links obesity with low-grade inflammation which may originate from adipose tissue that secretes a plethora of pro- and anti-inflammatory cytokines termed adipokines. Adiponectin and leptin have evolved as crucial signals in many obesity-related pathologies including non-alcoholic fatty liver disease (NAFLD. Whereas adiponectin deficiency might be critically involved in the pro-inflammatory state associated with obesity and related disorders, overproduction of leptin, a rather pro-inflammatory mediator, is considered of equal relevance. An imbalanced adipokine profile in obesity consecutively contributes to metabolic inflammation in NAFLD, which is associated with a substantial risk for developing hepatocellular carcinoma (HCC also in the non-cirrhotic stage of disease. Both adiponectin and leptin have been related to liver tumorigenesis especially in preclinical models. This review covers recent advances in our understanding of some adipokines in NAFLD and associated HCC.

    We aim to study the impact of the baby boomer (BB) generation, a birth-specific cohort (born 1945-1965) on hepatocellular carcinoma (HCC)-related liver transplantation (LT) in patients with chronic hepatitis C virus (HCV), alcoholic liver disease (ALD), and non-alcoholic steatohepatitis (NASH). We performed a retrospective analysis using the United Network for Organ Sharing (UNOS)/Organ Procurement Transplant Network (OPTN) database from 2003 to 2014 to compare HCC-related liver transplant surgery trends between two cohorts-the BB and non-BB-with a secondary diagnosis of HCV, ALD, or NASH. From 2003-2014, there were a total of 8313 liver transplant recipients for the indication of HCC secondary to HCV, ALD, or NASH. Of the total, 6658 (80.1%) HCC-related liver transplant recipients were BB. The number of liver transplant surgeries for the indication of HCC increased significantly in NASH (+1327%), HCV (+382%), and ALD (+286%) during the study period. The proportion of BB who underwent LT for HCC was the highest in HCV (84.7%), followed by NASH (70.3%) and ALD (64.7%). The recommendations for birth-cohort specific HCV screening stemmed from a greater understanding of the high prevalence of chronic HCV and HCV-related HCC within BB. The rising number of HCC-related LT among BB with ALD and NASH suggests the need for increased awareness and improved preventative screening/surveillance measures within NASH and ALD cohorts as well.

    Magnetic resonance cholangiopancreatography (MRCP) is one of many newer noninvasive tests that can image the biliary tree. To precisely estimate the overall sensitivity and specificity of MRCP in suspected biliary obstruction and to evaluate clinically important subgroups. MEDLINE search (January 1987 to March 2003) for studies in English or French, bibliographies, and subject matter experts. Studies were included if they allowed construction of 2x2 contingency tables of MRCP compared with a reasonable gold standard for at least 1 of the following: the presence, level, or cause of biliary obstruction. Two independent observers graded study quality, which included consecutive enrollment, blinding, use of a single (versus composite) gold standard, and nonselective use of the gold standard. Logistic regression was used to examine the influence of publication year, quality score, proportion of patients having a direct gold standard, and clinical context on diagnostic performance. Of 498 studies identified, 67 were included (4711 patients). Mixed-effect models were used to estimate the sensitivity and specificity, and quantitative receiver-operating characteristic analysis was performed. Magnetic resonance cholangiopancreatography had a high overall pooled sensitivity (95% (+/-1.96 SD: spread of SD, 75% to 99%) and specificity (97% (spread of SD, 86% to 99 %)) The procedure was less sensitive for stones (92%; odds ratio, 0.51 (CI, 0.35 to 0.75) and malignant conditions (88%; odds ratio, 0.28 (CI, 0.18 to 0.44f) than for the presence of obstruction, In addition, diagnostic performance was higher in studies that were larger, did not use consecutive enrollment, and did not use gold standard assessment for some patients. Magnetic resonance cholangiopancreatography is a noninvasive imaging test with excellent overall sensitivity and specificity for demonstrating the level and presence of biliary obstruction; however, it seems less sensitive for detecting stones or

    Morbid obese patients have a high rate of nonalcoholic fatty liver disease (NAFLD) and nonalcoholic steatohepatitis (NASH). NASH is related to the progression and poor evolution of chronic hepatopathy in NAFLD, so that its detection makes it possible to identify the subjects who are most at risk in order to prioritize treatment. The ELF test (Enhanced Liver Fibrosis test; Siemens Diagnostics, NY, USA) has been assessed for its capacity to detect fibrosis in patients with NAFLD, but its capacity for diagnosing NASH has not been checked. Our objective is to determine the utility of the ELF test for detecting NASH in morbid obese patients with suspected NAFLD. ELF values were determined in a cohort of obese patients who underwent bariatric surgery with suspected NAFLD. Liver biopsy was used as the reference standard. The values of ELF were significantly higher in patients with NASH (p = 0.002) and in those who presented with metabolic syndrome (p = 0.047). An ELF cut-off point of 8.72 allows the detection of patients with NASH with a sensitivity of 71.4% and a specificity of 74.1% (AUC = 0.742, p = 0.002). The ELF test is efficient for the identification of obese patients with NAFLD and early signs of steatohepatitis and fibrosis.

    Nuclear receptors are transcription factors which sense changing environmental or hormonal signals and effect transcriptional changes to regulate core life functions including growth, development, and reproduction. To support this function, following ligand-activation by xenobiotics, members of subfamily 1 nuclear receptors (NR1s) may heterodimerize with the retinoid X receptor (RXR) to regulate transcription of genes involved in energy and xenobiotic metabolism and inflammation. Several of these receptors including the peroxisome proliferator-activated receptors (PPARs), the pregnane and xenobiotic receptor (PXR), the constitutive androstane receptor (CAR), the liver X receptor (LXR) and the farnesoid X receptor (FXR) are key regulators of the gut:liver:adipose axis and serve to coordinate metabolic responses across organ systems between the fed and fasting states. Non-alcoholic fatty liver disease (NAFLD) is the most common liver disease and may progress to cirrhosis and even hepatocellular carcinoma. NAFLD is associated with inappropriate nuclear receptor function and perturbations along the gut:liver:adipose axis including obesity, increased intestinal permeability with systemic inflammation, abnormal hepatic lipid metabolism, and insulin resistance. Environmental chemicals may compound the problem by directly interacting with nuclear receptors leading to metabolic confusion and the inability to differentiate fed from fasting conditions. This review focuses on the impact of nuclear receptors in the pathogenesis and treatment of NAFLD. Clinical trials including PIVENS and FLINT demonstrate that nuclear receptor targeted therapies may lead to the paradoxical dissociation of steatosis, inflammation, fibrosis, insulin resistance, dyslipidemia and obesity. Novel strategies currently under development (including tissue-specific ligands and dual receptor agonists) may be required to separate the beneficial effects of nuclear receptor activation from unwanted metabolic

    Full Text Available Aim. To examine the association between lifetime alcohol consumption and significant liver disease in type 2 diabetic patients with NAFLD. Methods. A cross-sectional study assessing 151 patients with NAFLD at risk of clinically significant liver disease. NAFLD fibrosis severity was classified by transient elastography; liver stiffness measurements ≥8.2 kPa defined significant fibrosis. Lifetime drinking history classified patients into nondrinkers, light drinkers (always ≤20 g/day, and moderate drinkers (any period with intake >20 g/day. Result. Compared with lifetime nondrinkers, light and moderate drinkers were more likely to be male (p=0.008 and to be Caucasian (p=0.007 and to have a history of cigarette smoking (p=0.000, obstructive sleep apnea (p=0.003, and self-reported depression (p=0.003. Moderate drinkers required ≥3 hypoglycemic agents to maintain diabetic control (p=0.041 and fibrate medication to lower blood triglyceride levels (p=0.044. Compared to lifetime nondrinkers, light drinkers had 1.79 (95% CI: 0.67–4.82; p=0.247 and moderate drinkers had 0.91 (95% CI: 0.27–3.10; p=0.881 times the odds of having liver stiffness measurements ≥8.2 kPa (adjusted for age, gender, and body mass index. Conclusions. In diabetic patients with NAFLD, light or moderate lifetime alcohol consumption was not significantly associated with liver fibrosis. The impact of lifetime alcohol intake on fibrosis progression and diabetic comorbidities, in particular obstructive sleep apnea and hypertriglyceridemia, requires further investigation.

  3. Phytosterols, Lipid Administration, and Liver Disease During Parenteral Nutrition.

    Science.gov (United States)

    Zaloga, Gary P

    2015-09-01

    Phytosterols are plant-derived sterols that are structurally and functionally analogous to cholesterol in vertebrate animals. Phytosterols are found in many foods and are part of the normal human diet. However, absorption of phytosterols from the diet is minimal. Most lipid emulsions used for parenteral nutrition are based on vegetable oils. As a result, phytosterol administration occurs during intravenous administration of lipid. Levels of phytosterols in the blood and tissues may reach high levels during parenteral lipid administration and may be toxic to cells. Phytosterols are not fully metabolized by the human body and must be excreted through the hepatobiliary system. Accumulating scientific evidence suggests that administration of high doses of intravenous lipids that are high in phytosterols contributes to the development of parenteral nutrition-associated liver disease. In this review, mechanisms by which lipids and phytosterols may cause cholestasis are discussed. Human studies of the association of phytosterols with liver disease are reviewed. In addition, clinical studies of lipid/phytosterol reduction for reversing and/or preventing parenteral nutrition associated liver disease are discussed. © 2015 American Society for Parenteral and Enteral Nutrition.

    2015-01-01

    In the Western world, nonalcoholic fatty liver disease (NAFLD) is considered as one of the most significant liver diseases of the twenty-first century. Its development is certainly driven by environmental factors, but it is also regulated by genetic background. The role of heritability has been widely demonstrated by several epidemiological, familial, and twin studies and case series, and likely reflects the wide inter-individual and inter-ethnic genetic variability in systemic metabolism and wound healing response processes. Consistent with this idea, genome-wide association studies have clearly identified Patatin-like phosholipase domain-containing 3 gene variant I148M as a major player in the development and progression of NAFLD. More recently, the transmembrane 6 superfamily member 2 E167K variant emerged as a relevant contributor in both NAFLD pathogenesis and cardiovascular outcomes. Furthermore, numerous case-control studies have been performed to elucidate the potential role of candidate genes in the pathogenesis and progression of fatty liver, although findings are sometimes contradictory. Accordingly, we performed a comprehensive literature search and review on the role of genetics in NAFLD. We emphasize the strengths and weaknesses of the available literature and outline the putative role of each genetic variant in influencing susceptibility and/or progression of the disease.

    2013-12-01

    Full Text Available Osteoporosis and osteopenia are alterations in bone mineral density (BMD that frequently occur in the context of chronic liver disease (CLD. These alterations have been studied predominantly in chronic cholestatic disease and cirrhosis of the liver. Alcohol consumption is an independent risk factor for the onset of osteoporosis, whose estimated prevalence in patients with alcoholic liver disease (ALD ranges between 5 % and 40 %. The loss of BMD in ALD is the result of an imbalance between bone formation and resorption. Its pathogenesis is multifactorial and includes the toxic effects of alcohol on bone and endocrine and nutritional disorders secondary to alcoholism and a deficiency of osteocalcin, vitamin D and insulin growth factor-1. The diagnosis of BMD alterations in ALD is based on its measurement using bone densitometry. Treatment includes smoking and alcohol cessation and general measures such as changes in nutrition and exercise. Calcium and vitamin D supplements are recommended in all patients with ALD and osteoporosis. Bisphosphonates are the most commonly prescribed drugs for the specific treatment of this condition. Alternatives include raloxifene, hormone replacement therapy and calcitonin. This review will address the most important aspects involved in the clinical management of abnormal BMD in the context of ALD, including its prevalence, pathogenesis and diagnosis. We will also review the treatment of osteoporosis in CLD in general, focusing on specific aspects related to bone loss in ALD.

  6. Fructose Consumption, Lipogenesis, and Non-Alcoholic Fatty Liver Disease.

    Ter Horst, Kasper W; Serlie, Mireille J

    2017-09-06

    Increased fructose consumption has been suggested to contribute to non-alcoholic fatty liver disease (NAFLD), dyslipidemia, and insulin resistance, but a causal role of fructose in these metabolic diseases remains debated. Mechanistically, hepatic fructose metabolism yields precursors that can be used for gluconeogenesis and de novo lipogenesis (DNL). Fructose-derived precursors also act as nutritional regulators of the transcription factors, including ChREBP and SREBP1c, that regulate the expression of hepatic gluconeogenesis and DNL genes. In support of these mechanisms, fructose intake increases hepatic gluconeogenesis and DNL and raises plasma glucose and triglyceride levels in humans. However, epidemiological and fructose-intervention studies have had inconclusive results with respect to liver fat, and there is currently no good human evidence that fructose, when consumed in isocaloric amounts, causes more liver fat accumulation than other energy-dense nutrients. In this review, we aim to provide an overview of the seemingly contradicting literature on fructose and NAFLD. We outline fructose physiology, the mechanisms that link fructose to NAFLD, and the available evidence from human studies. From this framework, we conclude that the cellular mechanisms underlying hepatic fructose metabolism will likely reveal novel targets for the treatment of NAFLD, dyslipidemia, and hepatic insulin resistance. Finally, fructose-containing sugars are a major source of excess calories, suggesting that a reduction of their intake has potential for the prevention of NAFLD and other obesity-related diseases.

    Malnutrition is a major contributor to morbidity and mortality from pediatric liver disease. We investigated the prevalence of both malnutrition and high nutritional risk in hospitalized children with liver disease as well as the rate of in-hospital nutritional support. A total of 2,874 hospitalized children and adolescents with liver disease aged 1 to 17 years (inclusive) were enrolled. Malnutrition was screened by anthropometric measures (height-for-age, weight-for-height, weight-for-age, and BMI- for-age z-scores). The Screening Tool for Risk on Nutritional Status and Growth (STRONGkids) was used to evaluate nutritional risk status. Nutrition markers in blood, rate of nutritional support, length of hospital stay, and hospital fees were compared among nutritional risk groups. The overall prevalence of malnutrition was 38.6%. About 20.0% of children had high nutritional risk, and prevalence of malnutrition was markedly greater in the high nutritional risk group compared with the moderate risk group (67.9% vs 31.3%). Serum albumin and prealbumin differed significantly between high and moderate risk groups (pnutritional risk and 3.5% with moderate nutritional risk received nutrition support during hospitalization. Children with high nutritional risk had longer hospital stays and greater hospital costs (pnutritional risk is also prevalent at admission. Albumin and prealbumin are sensitive markers for distinguishing nutritional risk groups. High nutritional risk prolongs length of stay and increases hospital costs. The nutritional support rate is still low and requires standardization.

    Pathologists are likely to encounter IgG4-related disease in several organ systems. This article focuses on helping pathologists diagnose IgG4-related disease in the hepatobiliary system. Missing the diagnosis can result in unnecessary organ damage and/or unnecessary surgical and cancer therapy. In the liver, tumefactive lesion(s) involving the bile ducts with storiform fibrosis and an IgG4-enriched lymphoplasmacytic infiltrate are highly concerning for IgG4-related disease. The recent identification of oligoclonal populations of T cells and B cells in IgG4-related disease may lead to molecular tests, new therapeutics, and a greater mechanistic understanding of the disease.

    2014-01-01

    Nonalcoholic fatty liver disease (NAFLD), the most common of chronic liver disease in Western Country, is closely related to insulin resistance and oxidative stress and includes a wide spectrum of liver diseases ranging from steatosis alone, usually a benign and non-progressive condition, to nonalcoholic steatohepatitis (NASH), which may progress to liver fibrosis and cirrhosis. NAFLD is considered the hepatic manifestation of the metabolic syndrome with which shares several characteristics, however recent data suggest that NAFLD is linked to increased cardiovascular risk independently of the broad spectrum of risk factors of metabolic syndrome. Accumulating evidence suggests that the clinical burden of NAFLD is not restricted to liver-related morbidity and mortality, with the majority of deaths in NAFLD patients related to cardiovascular disease and cancer and not to the progression of liver disease. Retrospective and prospective studies provide evidence of a strong association between NAFLD and subclinical manifestation of atherosclerosis (increased intima-media thickness, endothelial dysfunction, arterial stiffness, impaired left ventricular function and coronary calcification). A general agreement emerging from these studies indicates that patients with NASH are at higher risk of cardiovascular diseases than those with simple steatosis, emphasizing the role of chronic inflammation in the pathogenesis of atherosclerosis of these patients. It is very likely that the different mechanisms involved in the pathogenesis of atherosclerosis in patients with NAFLD have a different relevance in the patients according to individual genetic background. In conclusion, in the presence of NAFLD patients should undergo a complete cardiovascular evaluation to prevent future atherosclerotic complications. Specific life-style modification and aggressive pharmaceutical modification will not only reduce the progression of liver disease, but also reduce morbidity for cardiovascular

    Full Text Available BackgroundLiver biopsy is recommended as the gold standard method for assessing the stage of liver fibrosis in patients with chronic liver disease. However, it is invasive, with potential risks and complications. Elastography is an ultrasound technique that provides information of changes in the liver tissue, evaluating tissue elasticity and acoustic radiation force impulse is one of the available techniques.ObjectiveThe main objective of this study was to evaluate the sensitivity and specificity of acoustic radiation force impulse comparing to liver biopsy to evaluate fibrosis in patients with chronic hepatitis C virus and nonalcoholic fatty liver disease.MethodsTwenty four patients were included, everyone underwent liver biopsy and acoustic radiation force impulse, and the results were compared with values described in the literature by several authors.ResultsIn the population of patients with chronic hepatitis C, our data were better correlated with data published by Carmen Fierbinteanu-Braticevici et al., with an accuracy of 82.4%, sensitivity of 71.4% and specificity of 90%. For nonalcoholic fatty liver disease, our data were better correlated with data published by Masato Yoneda et al., with an accuracy of 85.7%, sensitivity 80% and specificity of 100%.ConclusionAcoustic radiation force impulse is a method with good accuracy to distinguish initial fibrosis from advanced fibrosis in hepatitis C virus and nonalcoholic fatty liver disease and can replace biopsy in most cases.

    Due to the worldwide epidemic of obesity, nonalcoholic fatty liver disease (NAFLD) has become the most common cause of elevated liver enzymes. NAFLD represents a spectrum of liver injury ranging from simple steatosis to nonalcoholic steatohepatitis (NASH) which may progress to advanced fibrosis and cirrhosis. Individuals with NAFLD, especially those with metabolic syndrome, have higher overall mortality, cardiovascular mortality, and liver-related mortality compared with the general population. According to the population-based studies, NAFLD and NASH are more prevalent in males and in Hispanics. Both the gender and racial ethnic differences in NAFLD and NASH are likely attributed to interaction between environmental, behavioral, and genetic factors. Using genome-wide association studies, several genetic variants have been identified to be associated with NAFLD/NASH. However, these variants account for only a small amount of variation in hepatic steatosis among ethnic groups and may serve as modifiers of the natural history of NAFLD. Alternatively, these variants may not be the causative variants but simply markers representing a larger body of genetic variations. In this article, we provide a concise review of the gender and racial differences in the prevalence of NAFLD and NASH in adults. We also discuss the possible mechanisms for these disparities.

    AIM: To evaluate the glycated hemoglobin (HbA 1c) determination methods and to determine fructosamine in patients with chronic hepatitis, compensated cirrhosis and in patients with chronic hepatitis treated with ribavirin. METHODS: HbA1c values were determined in 15 patients with compensated liver cirrhosis and in 20 patients with chronic hepatitis using the ion-exchange high performance liquid chromatography and the immunoassay methods. Fructosamine was determined using nitroblue tetrazolium. RESULTS: Forty percent of patients with liver cirrhosis had HbA1c results below the non-diabetic reference range by at least one HbA1c method, while fructosamine results were either within the reference range or elevated. Twenty percent of patients with chronic hepatitis (hepatic fibrosis) had HbA1c results below the non -diabetic reference range by at least one HbA1c method. In patients with chronic hepatitis treated with ribavirin, 50% of HbA1c results were below the non-diabetic reference using at least one of the HbA1c methods. CONCLUSION: Only evaluated in context with all liver function parameters as well as a red blood count including reticulocytes, HbA 1c results should be used in patients with advanced liver disease. HbA 1c and fructosamine measurements should be used with caution when evaluating long-term glucose control in patients with hepatic cirrhosis or in patients with chronic hepatitis and ribavirin treatment.

    Polyploidization is one of the most dramatic changes that can occur in the genome. In the liver, physiological polyploidization events occur during both liver development and throughout adult life. Here, we determined that a pathological polyploidization takes place in nonalcoholic fatty liver disease (NAFLD), a widespread hepatic metabolic disorder that is believed to be a risk factor for hepatocellular carcinoma (HCC). In murine models of NAFLD, the parenchyma of fatty livers displayed alterations of the polyploidization process, including the presence of a large proportion of highly polyploid mononuclear cells, which are rarely observed in normal hepatic parenchyma. Biopsies from patients with nonalcoholic steatohepatitis (NASH) revealed the presence of alterations in hepatocyte ploidy compared with tissue from control individuals. Hepatocytes from NAFLD mice revealed that progression through the S/G2 phases of the cell cycle was inefficient. This alteration was associated with activation of a G2/M DNA damage checkpoint, which prevented activation of the cyclin B1/CDK1 complex. Furthermore, we determined that oxidative stress promotes the appearance of highly polyploid cells, and antioxidant-treated NAFLD hepatocytes resumed normal cell division and returned to a physiological state of polyploidy. Collectively, these findings indicate that oxidative stress promotes pathological polyploidization and suggest that this is an early event in NAFLD that may contribute to HCC development.

    Hepatic steatosis is the buildup of lipids within hepatocytes. It is the simplest stage in nonalcoholic fatty liver disease (NAFLD). It occurs in approximately 30% of the general population and as much as 90% of the obese population in the United States. It may progress to nonalcoholic steatohepatitis, which is a state of hepatocellular inflammation and damage in response to the accumulated fat. Liver biopsy remains the gold standard tool to diagnose and stage NAFLD. However, it comes with the risk of complications ranging from simple pain to life-threatening bleeding. It is also associated with sampling error. For these reasons, a variety of noninvasive radiological markers, including ultrasound, computed tomography, magnetic resonance spectroscopy, and the controlled attenuation parameter using transient elastography and Xenon-133 scan have been proposed to increase our ability to diagnose NAFLD, hence avoiding liver biopsy. The aim of this review is to discuss the utility and accuracy of using available noninvasive diagnostic modalities for fatty liver in NAFLD. PMID:25843191

    Early diagnosis and treatment of the respiratory and gastrointestinal complications of cystic fibrosis (CF) have led to improved survival with many patients living beyond the fourth decade. Along with this increased life expectancy is the risk of further disease associated with the chronic manifestations of their condition. We report a patient with documented CF related liver disease for which he was under routine surveillance that presented with histologically proven hepatocellular carcinoma (HCC). It is important that physicians are aware of this association as increased vigilance may lead to earlier diagnosis and perhaps, a better outcome.

    Full Text Available Neurodegenerative disorders and cancer are severe diseases threatening human health. The glaring differences between neurons and cancer cells mask the processes involved in their pathogenesis. Defects in cell cycle, DNA repair and cell differentiation can determine unlimited proliferation in cancer, or conversely, compromise neuronal plasticity, leading to cell death and neurodegeneration.Alteration in regulatory networks affecting gene expression contribute to human diseases' onset, including neurodegenerative disorders, and deregulation of non-coding RNAs - particularly microRNAs - is supposed to have a significant impact.Recently, competitive endogenous RNAs - acting as sponges - have been identified in cancer, indicating a new and intricate regulatory network. Given that neurodegenerative disorders and cancer share altered genes and pathways, and considering the emerging role of microRNAs in neurogenesis, we hypothesize competitive endogenous RNAs may be implicated in neurodegenerative diseases. Here we propose, and computationally predict, such regulatory mechanism may be shared between the diseases. It is predictable that similar regulation occurs in other complex diseases, and further investigation is needed.

    Parenteral nutrition–associated liver disease (PNALD) is a serious complication of PN in infants who do not tolerate enteral feedings, especially those with acquired or congenital intestinal diseases. Yet, the mechanisms underlying PNALD are poorly understood. It has been suggested that a component of soy oil (SO) lipid emulsions in PN solutions, such as plant sterols (phytosterols), may be responsible for PNALD, and that use of fish oil (FO)–based lipid emulsions may be protective. We used a mouse model of PNALD combining PN infusion with intestinal injury to demonstrate that SO-based PN solution causes liver damage and hepatic macrophage activation and that PN solutions that are FO-based or devoid of all lipids prevent these processes. We have furthermore demonstrated that a factor in the SO lipid emulsions, stigmasterol, promotes cholestasis, liver injury, and liver macrophage activation in this model and that this effect may be mediated through suppression of canalicular bile transporter expression (Abcb11/BSEP, Abcc2/MRP2) via antagonism of the nuclear receptors Fxr and Lxr, and failure of up-regulation of the hepatic sterol exporters (Abcg5/g8/ABCG5/8). This study provides experimental evidence that plant sterols in lipid emulsions are a major factor responsible for PNALD and that the absence or reduction of plant sterols is one of the mechanisms for hepatic protection in infants receiving FO-based PN or lipid minimization PN treatment. Modification of lipid constituents in PN solutions is thus a promising strategy to reduce incidence and severity of PNALD. PMID:24107776

    Full Text Available Objective. Several tests are available in the diagnostics of sporadic Creutzfeldt-Jakob disease (sCJD; however, none of these is conclusive. We review the values of these tests, from an intensive care unit (ICU perspective. Methods. Case report and review of the literature. Results. A 53-year-old woman initially presenting with psychiatric symptoms developed myoclonus and was admitted 1 month later to the ICU with a suspected nonconvulsive status epilepticus and respiratory insufficiency, probably due to extensive antiepileptic drug therapy. Typical MRI and EEG findings and a positive 14-3-3 protein led to the diagnosis of sCJD. All treatments were terminated, and autopsy confirmed sCJD. Conclusions. Clinical signs combined with MRI, EEG, and 14-3-3 and/or tau protein determination might be sufficient to diagnose or exclude sCJD and may therefore prevent the application of unnecessary diagnostic tests.

    Magnetic resonance imaging (MR) (0.35T) and computed tomography (CT) were compared in 400 consecutive patients with suspected disease of the brain and cervical spinal cord. Of 325 positive diagnoses, MR detected abnormality while CT was normal in 93; MR was more specific in 68; MR and CT gave equivalent information in 129; CT was more specific in 32; and CT was positive while MR was normal in 3. MR was superior to CT in detection of multiple sclerosis, subcortical arteriosclerotic encephalopathy, posterior fossa infarcts and tumors, small extra-axial fluid collections, and cervical syringomyelia. CT was preferable in evaluation of meningiomas and separation of tumor from edema. CT takes less time and may be preferable in patients with acute trauma as well as very young or elderly individuals. Thus the two studies should be considered complementary.

    Full Text Available BACKGROUND Liver plays an important role in normal erythropoiesis and synthesis of clotting factors. Chronic liver disease (CLD patients are frequently associated with abnormalities in haematological parameters. MATERIALS AND METHODS This was an observational study conducted among diagnosed CLD patients over a period of 1 year from 2013 to 2014. Various haematological abnormalities in 75 CLD patients were studied. Relevant details were obtained in structured format. RESULTS The mean age of the study group 49.2 years. Male-to-female ratio was 5.8:1. Aetiologies of cirrhosis were alcoholism (61.3%, diabetes mellitus (26.7% and dyslipidaemia (13%. 88% patients were anaemic with severe anaemia (Hb <8 gm% observed in 33.3% patients with mean Hb being 8.76 gm%. Mean Hb in alcohol-related CLDs were lower than CLDs due to other aetiologies (8.62 gm% vs. 9.36 gm%. Most common anaemia observed was normocytic normochromic anaemia (40.9%. 26.7% had leucopenia and 88% had thrombocytopenia. Normal ferritin levels were observed in 6.7%, decreased in 16% and increased in the remaining cases of which a level of more than 900 ng/mL was observed in 18.7% cases. Mean CTP (ChildTurcotte-Pugh score of the study group was 11.1. 80% of patients belong to child C. Patients with high ferritin levels had high CTP score (P-0.001. Platelet count decreases as CTP score increases (P-0.000 and as spleen size increases (P-0.001. CONCLUSION Most common haematological abnormalities observed were thrombocytopenia and anaemia. Severe anaemia was seen in males and alcoholics. Thrombocytopenia was more in those with advanced liver disease and large spleen. High serum ferritin level correlate well with advanced liver disease.

    Obesity and nonalcoholic fatty liver disease (NAFLD) can increase susceptibility to hepatotoxicity induced by some xenobiotics including drugs, but the involved mechanisms are poorly understood. For acetaminophen (APAP), a role of hepatic cytochrome P450 2E1 (CYP2E1) is suspected since the activity of this enzyme is consistently enhanced during NAFLD. The first aim of our study was to set up a cellular model of NAFLD characterized not only by triglyceride accumulation but also by higher CYP2E1 activity. To this end, human HepaRG cells were incubated for one week with stearic acid or oleic acid, in the presence of different concentrations of insulin. Although cellular triglycerides and the expression of lipid-responsive genes were similar with both fatty acids, CYP2E1 activity was significantly increased only by stearic acid. CYP2E1 activity was reduced by insulin and this effect was reproduced in cultured primary human hepatocytes. Next, APAP cytotoxicity was assessed in HepaRG cells with or without lipid accretion and CYP2E1 induction. Experiments with a large range of APAP concentrations showed that the loss of ATP and glutathione was almost always greater in the presence of stearic acid. In cells pretreated with the CYP2E1 inhibitor chlormethiazole, recovery of ATP was significantly higher in the presence of stearate with low (2.5 mM) or high (20 mM) concentrations of APAP. Levels of APAP-glucuronide were significantly enhanced by insulin. Hence, HepaRG cells can be used as a valuable model of NAFLD to unveil important metabolic and hormonal factors which can increase susceptibility to drug-induced hepatotoxicity. - Highlights: • Nonalcoholic fatty liver disease (NAFLD) is frequent in obese individuals. • NAFLD can favor hepatotoxicity induced by some drugs including acetaminophen (APAP). • A model of NAFLD was set up by using HepaRG cells incubated with stearate or oleate. • Stearate-loaded HepaRG cells presented higher cytochrome P450 2E1 (CYP2E1

    To describe the prevalence, diagnosis, treatment, and outcomes of end stage liver disease (ESLD) patients with severe epistaxis thought to be severe upper gastrointestinal hemorrhage (UGIH). This observational single center study included all consecutive patients with ESLD and epistaxis identified from consecutive subjects hospitalized with suspected UGIH and prospectively enrolled in our databases of severe UGIH between 1998 and 2011. A total of 1249 patients were registered for severe UGIH in the data basis, 461 (36.9%) were cirrhotics. Epistaxis rather than UGIH was the bleeding source in 20 patients. All patients had severe coagulopathy. Epistaxis was initially controlled in all cases. Fifteen (75%) subjects required posterior nasal packing and 2 (10%) embolization in addition to correction of coagulopathy. Five (25%) patients died in the hospital, 12 (60%) received orthotopic liver transplantation (OLT), and 3 (15%) were discharged without OLT. The mortality rate was 63% in patients without OLT. Severe epistaxis in patients with ESLD is (1) a diagnosis of exclusion that requires upper endoscopy to exclude severe UGIH; and (2) associated with a high mortality rate in patients not receiving OLT.

    Alternative explanations are common in suspected drug-induced liver injury (DILI) and account for up to 47.1% of analyzed cases. This raised the question of whether a similar frequency may prevail in cases of assumed herb-induced liver injury (HILI). We searched the Medline database for the following terms: herbs, herbal drugs, herbal dietary supplements, hepatotoxic herbs, herbal hepatotoxicity, and herb-induced liver injury. Additional terms specifically addressed single herbs and herbal products: black cohosh, Greater Celandine, green tea, Herbalife products, Hydroxycut, kava, and Pelargonium sidoides. We retrieved 23 published case series and regulatory assessments related to hepatotoxicity by herbs and herbal dietary supplements with alternative causes. The 23 publications comprised 573 cases of initially suspected HILI; alternative causes were evident in 278/573 cases (48.5%). Among them were hepatitis by various viruses (9.7%), autoimmune diseases (10.4%), nonalcoholic and alcoholic liver diseases (5.4%), liver injury by comedication (DILI and other HILI) (43.9%), and liver involvement in infectious diseases (4.7%). Biliary and pancreatic diseases were frequent alternative diagnoses (11.5%), raising therapeutic problems if specific treatment is withheld; pre-existing liver diseases including cirrhosis (9.7%) were additional confounding variables. Other diagnoses were rare, but possibly relevant for the individual patient. In 573 cases of initially assumed HILI, 48.5% showed alternative causes unrelated to the initially incriminated herb, herbal drug, or herbal dietary supplement, calling for thorough clinical evaluations and appropriate causality assessments in future cases of suspected HILI.

    Lipocalin 2 (LCN2) is induced in the injured liver and associated with inflammation. Aim of the present study was to evaluate whether serum LCN2 is a non-invasive marker to assess hepatic steatosis in patients with non-alcoholic fatty liver disease (NAFLD) or residual liver function in patients with liver cirrhosis. Therefore, LCN2 was measured by ELISA in serum of 32 randomly selected patients without fatty liver (controls), 24 patients with ultrasound diagnosed NAFLD and 42 patients with liver cirrhosis mainly due to alcohol. Systemic LCN2 was comparable in patients with liver steatosis, those with liver cirrhosis and controls. LCN2 negatively correlated with bilirubin in both cohorts. In cirrhosis, LCN2 was not associated with more advanced liver injury defined by the CHILD-PUGH score and model for end-stage liver disease score. Resistin but not C-reactive protein or chemerin positively correlated with LCN2. LCN2 levels were not increased in patients with ascites or patients with esophageal varices. Consequently, reduction of portal pressure by transjugular intrahepatic portosystemic shunt did not affect LCN2 levels. Hepatic venous blood (HVS), portal venous blood and systemic venous blood levels of LCN2 were similar. HVS LCN2 was unchanged in patients with end-stage liver cirrhosis compared to those with well-compensated disease arguing against increased hepatic release. Current data exclude that serum LCN2 is of any value as steatosis marker in patients with NAFLD and indicator of liver function in patients with alcoholic liver cirrhosis.

    Liver scintigrams with Tc-99m phytate were reviewed in a total of 64 consecutive patients, comprising 28 with chronic hepatitis and 36 with liver cirrhosis. Reticuloendothelial (RES) function, plasma endotoxin (Et) levels and findings of general liver function tests were used as reference parameters to determine the diagnostic ability of liver scintigraphy. Multivariate analyses revealed that liver scintigrams had a strong correlation with RES function and Et levels in terms of morphology of the liver and hepatic and bone marrow Tc-99m uptake. General liver function tests revealed gamma globulin to be correlated with hepatic uptake and the degree of splenogemaly on liver scintigrams; and ICG levels at 15 min to be correlated with bone marrow and splenic uptake. Accuracy of liver scintigraphy was 73% for chronic hepatitis, which was inferior to general liver function tests (83%). When both modalities were combined, diangostic accuracy increased to 95%. Liver scintigraphy seems to be useful as a complementary approach. (Namekawa, K).

    Identifying patients with obstructive coronary artery disease can be challenging for primary care physicians. Advances in precision medicine may help augment clinical tools and redefine the paradigm for evaluating coronary artery disease in the outpatient setting. A blood-based age/sex/gene expression score (ASGES) incorporating key features of precision medicine has shown clinical validity with a 96% negative predictive value and 89% sensitivity in estimating a symptomatic patient's current likelihood of obstructive coronary artery disease. To better characterize the clinical utility of the ASGES and measure its impact on clinician decision-making, a community-based registry was established. The prospective PRESET Registry (NCT01677156) enrolled stable, nonacute adult patients presenting with typical or atypical symptoms suggestive of obstructive coronary artery disease from 21 US primary care practices from August 2012 to August 2014. Demographics, clinical characteristics, and ASGES results (predefined as low [ASGES ≤15] or elevated [ASGES >15]) were collected, as were referrals to Cardiology or further functional/anatomic cardiac testing after ASGES testing. Patients were followed for 1 year post ASGES testing. Among the 566-patient cohort (median age 56 years), clinicians referred 26/252 (10%) of patients with low scores vs 137/314 (44%) of patients with elevated scores to Cardiology or advanced cardiac testing for further evaluation (unadjusted odds ratio 0.15, P precision medicine in the delivery of cardiovascular care.

    Full Text Available In patients with Parkinson’s disease (PD, the molecularly misfolded form of α-synuclein was recently identified in cutaneous autonomic nerve fibers which displayed increased accumulation even in early disease stages. However, the underlying mechanisms of synucleinopathic nerve damage and its implication for brain pathology in later life remain to be elucidated. To date, specific diagnostic tools to evaluate small fiber pathology and to discriminate neurodegenerative proteinopathies are rare. Recently, research has indicated that deposition of α-synuclein in cutaneous nerve fibers quantified via immunohistochemistry in superficial skin biopsies might be a valid marker of PD which could facilitate early diagnosis and monitoring of disease progression. However, lack of standardization of techniques to quantify neural α-synuclein deposition limits their utility in clinical practice. Additional challenges include the identification of potential distinct morphological patterns of intraneural α-synuclein deposition among synucleinopathies to facilitate diagnostic discrimination and determining the degree to which structural damage relates to dysfunction of nerve fibers targeted by α-synuclein. Answering these questions might improve our understanding of the pathophysiological role of small fiber neuropathy in Parkinson’s disease, help identify new treatment targets, and facilitate assessment of response to neuroprotective treatment.

    2012-01-01

    Full Text Available Nonalcoholic fatty liver disease (NAFLD and non-alcoholic steatohepatitis (NASH are multidisciplinary liver diseases that often accompany type 2 diabetes or metabolic syndrome, which are characterized by insulin resistance. Therefore, effective treatment of type 2 diabetes and metabolic syndrome should target not only the cardiometabolic abnormalities, but also the associated liver disorders. In the last decade, it has been shown that metformin, thiazolidinediones, vitamin E, ezetimibe, n-3 polyunsaturated fatty acids, renin-angiotensin system (RAS blockers, and antiobesity drugs may improve hepatic pathophysiological disorders as well as clinical parameters. Accordingly, insulin sensitizers, antioxidative agents, Niemann-Pick C1-like 1 (NPC1L1 inhibitors, RAS blockers, and drugs that target the central nervous system may represent candidate pharmacotherapies for NAFLD and possibly NASH. However, the efficacy, safety, and tolerability of long-term treatment (potentially for many years with these drugs have not been fully established. Furthermore, clinical trials have not comprehensively examined the efficacy of lipid-lowering drugs (i.e., statins, fibrates, and NPC1L1 inhibitors for the treatment of NAFLD. Although clinical evidence for RAS blockers and incretin-based agents (GLP-1 analogs and dipeptidyl peptidase-4 inhibitors is also lacking, these agents are promising in terms of their insulin-sensitizing and anti-inflammatory effects without causing weight gain.

    In the past decade, nonalcoholic fatty liver disease (NAFLD) had rapidly become one of the most common liver diseases. If efficient therapeutic strategies will not reduce the prevalence of NAFLD in children soon, serious deleterious effects on the quality of life of these patients in adulthood are expected. Lifestyle modification is the current first-line therapy for pediatric NAFLD, even though it is difficult to obtain and to maintain. Therefore, lifestyle changes are usually ineffective and long-lasting improvement of the NAFLD-associated liver damage is rarely observed. As guidelines for the management of NAFLD in children are still lacking, the identification of effective treatments represents a challenge for pediatric hepatologists in the near future. Here, we review the existing therapeutic approaches for treating NAFLD in children and overview all ongoing clinical trials for new promising drugs in pediatric setting. Considering the multifactorial pathogenesis and the wide spectrum of histological and clinical features of NAFLD, we believe that a drug mix, containing agents that are effective against the principal pathogenetic factors, associated with lifestyle modification, could represent the winning choice of treatment for pediatric NAFLD.

    2015-09-18

    The molecular mechanisms that lead to the progression of alcoholic liver disease have been actively examined for decades. Because the hepatic microtubule cytoskeleton supports innumerable cellular processes, it has been the focus of many such mechanistic studies. It has long been appreciated that α-tubulin is a major target for modification by highly reactive ethanol metabolites and reactive oxygen species. It is also now apparent that alcohol exposure induces post-translational modifications that are part of the natural repertoire, mainly acetylation. In this review, the modifications of the "tubulin code" are described as well as those adducts by ethanol metabolites. The potential cellular consequences of microtubule modification are described with a focus on alcohol-induced defects in protein trafficking and enhanced steatosis.

    Full Text Available The molecular mechanisms that lead to the progression of alcoholic liver disease have been actively examined for decades. Because the hepatic microtubule cytoskeleton supports innumerable cellular processes, it has been the focus of many such mechanistic studies. It has long been appreciated that α-tubulin is a major target for modification by highly reactive ethanol metabolites and reactive oxygen species. It is also now apparent that alcohol exposure induces post-translational modifications that are part of the natural repertoire, mainly acetylation. In this review, the modifications of the “tubulin code” are described as well as those adducts by ethanol metabolites. The potential cellular consequences of microtubule modification are described with a focus on alcohol-induced defects in protein trafficking and enhanced steatosis. Possible mechanisms that can explain hepatic dysfunction are described and how this relates to the onset of liver injury is discussed. Finally, we propose that agents that alter the cellular acetylation state may represent a novel therapeutic strategy for treating liver disease.

    Liver and spleen volume were measured by computed tomography (CT) using point counting technique. This method is very simple and applicable to any kind of CT scanner. The volumes of the livers and spleens estimated by this method correlated with the weights of the corresponding organs measured on autopsy or surgical operation, indication the accuracy and usefulness of this method. Hepatic and splenic volumes were estimated by this method in 48 patients with chronic liver disease and 13 subjects with non-hepatobiliary discase. The mean hepatic volume in non-alcoholic liver cirrhosis but not in alcoholic cirrhosis was significantly smaller than those in non-hepatobiliary disease and other chronic liver diseases. Alcoholic cirrhosis showed significantly larger liver volume than non-alcoholic cirrhosis. In alcoholic fibrosis, the mean hepatic volume was significantly larger than non-hepatobiliary disease. The mean splenic volumes both in alcoholic and non-alcoholic cirrhosis were significantly larger than in other disease. A significantly positive correlation between hepatic and splenic volumes was found in alcoholic cirrhosis but not in non-alcoholic cirrhosis. These results indicate that estimation of hepatic and splenic volumes by this method is useful for the analysis of the pathophysiology of chronic liver disease. (author)

    Full Text Available Background & Objectives: Non-alcoholic fatty liver disease, characterized by the deposition of fat in liver cells, can cause fibrosis, cirrhosis, and liver cell damage if not controlled. The aim of this study is to compare the effects of medication therapy and exercise training with diet on liver enzyme levels and liver sonography in patients with non-alcoholic fatty liver disease (NAFLD. Materials & Methods :In this quasi-experimental study, female patients with non-alcoholic fatty liver were randomly divided into two groups: medication therapy (n = 10 and exercise therapy (n = 10 for 8 weeks. During this period, the exercise group performed exercise training three days a week for 90 minutes per session. The drug was given to the medication group. In both groups, the diet was 500 calories less than their daily energy. Before and after intervention, blood tests and liver sonography were executed. All statistical analyses were done using SPSS for Windows version 20. Comparisons between and within groups were performed by Student's t-test and Wilcoxon test on paired and unpaired data. P < 0.05 was considered statistically significant. Results :In both groups, liver enzyme levels and disease severity in sonography reduced significantly (p<0.05. Conclusion: The findings of the present research showed that both methods of therapy have the same effect on reducing the severity of NAFLD.

    To examine the association between liver histological features and organ-specific insulin resistance indices calculated from 75-g oral glucose tolerance test data in patients with non-alcoholic fatty liver disease. Liver biopsy specimens were obtained from 72 patients with non-alcoholic fatty liver disease, and were scored for steatosis, grade and stage. Hepatic and skeletal muscle insulin resistance indices (hepatic insulin resistance index and Matsuda index, respectively) were calculated from 75-g oral glucose tolerance test data, and metabolic clearance rate was measured using the euglycemic hyperinsulinemic clamp method. The degree of hepatic steatosis, and grade and stage of non-alcoholic steatohepatitis were significantly correlated with Matsuda index (steatosis r = -0.45, P hepatic insulin resistance index. Multiple regression analyses adjusted for age, sex, body mass index and each histological score showed that the degree of hepatic steatosis (coefficient = -0.22, P steatosis and metabolic clearance rate (coefficient = -0.62, P = 0.059). Liver steatosis is associated with insulin resistance in skeletal muscle rather than in the liver in patients with non-alcoholic fatty liver disease, suggesting a central role of fatty liver in the development of peripheral insulin resistance and the existence of a network between the liver and skeletal muscle.

    The aim of this study was to investigate the additional value of single-photon emission computed tomography (SPECT) for patient staging compared to planar bone scanning in an unselected cohort of cancer patients. The study included 271 consecutive tumor patients in whom planar imaging and two-bed position SPECT of the spine and the pelvis had been performed. Retrospective image interpretation was performed independently for planar and SPECT scans. Findings were categorized as 'benign', 'equivocal', or malignant' on a lesion base, and as 'no metastatic disease', 'equivocal', or metastatic disease' on a patient base. Four hundred and forty seven lesions were detected by SPECT. Missing of lesions in planar images was rare (4.3% of all SPECT lesions). Planar findings differed from SPECT findings in 149 lesions (33.3%). Most of these 'inconsistent' lesions were rated as equivocal in the planar images but benign (14.5% of all lesions) or malignant (11.0%) by SPECT. On a patient base, 81.6% of patients with planar equivocal staging were classified as either benign (55.3%) or malignant (26.3%) by SPECT. Patients definitively staged as 'no metastatic disease' or 'metastatic disease' in planar images were staged differently by SPECT in only 3.7% of cases (up-staging in 2.6% and down-staging in 1.1%). Single-photon emission computed tomography changed a definite staging as based on planar images in less than 4% of the patients. In patients with planar equivocal staging, however, SPECT allowed a definite diagnosis in more than 80% of these cases, and, thus, should be performed routinely in patients with equivocal findings.

    Full Text Available Patients with chronic liver disease often suffer from unspecific symptoms and report severe impairment in the quality of life. The underlying mechanisms are multifactorial and include disease-specific but also liver related causes. The current analysis evaluated the association of hepatocellular apoptosis in non-viral chronic liver disease and health-related quality of life (HRQL. Furthermore we examined factors, which influence patient's physical and mental well-being.A total of 150 patients with non-infectious chronic liver disease were included between January 2014 and June 2015. The German version of the Chronic Liver Disease Questionnaire (CLDQ-D, a liver disease specific instrument to assess HRQL, was employed. Hepatocellular apoptosis was determined by measuring Cytokeratin 18 (CK18, M30 Apoptosense ELISA.Female gender (5.24 vs. 5.54, p = 0.04, diabetes mellitus type II (4.75 vs. 5.46, p<0.001 and daily drug intake (5.24 vs. 6.01, p = 0.003 were associated with a significant impairment in HRQL. HRQL was not significantly different between the examined liver diseases. Levels of CK18 were the highest in patients with NASH compared to all other disease entities (p<0.001. Interestingly, CK18 exhibited significant correlations with obesity (p<0.001 and hyperlipidemia (p<0.001. In patients with cirrhosis levels of CK18 correlated with the MELD score (r = 0.18, p = 0.03 and were significantly higher compared to patients without existing cirrhosis (265.5 U/l vs. 186.9U/l, p = 0.047. Additionally, CK18 showed a significant correlation with the presence and the degree of hepatic fibrosis (p = 0.003 and inflammation (p<0.001 in liver histology. Finally, there was a small negative association between CLDQ and CK18 (r = -0.16, p = 0.048.Different parameters are influencing HRQL and CK18 levels in chronic non-viral liver disease and the amount of hepatocellular apoptosis correlates with the impairment in HRQL in chronic non-viral liver diseases.

    Acute liver failure is a refractory disease and its prognosis, if not treated using liver transplantation, is extremely poor. It is a good candidate for regenerative medicine, where stem cell-based therapies play a central role. Mesenchymal stem cells (MSCs) are known to differentiate into multiple cell lineages including hepatocytes. Autologous cell transplant without any foreign gene induction is feasible using MSCs, thereby avoiding possible risks of tumorigenesis and immune rejection. Dental pulp also contains an MSC population that differentiates into hepatocytes. A point worthy of special mention is that dental pulp can be obtained from deciduous teeth during childhood and can be subsequently harvested when necessary after deposition in a tooth bank. MSCs have not only a regenerative capacity but also act in an anti-inflammatory manner via paracrine mechanisms. Promising efficacies and difficulties with the use of MSC derived from teeth are summarized in this review.

    We present 2 cases of teenager males presented with burning pain in extremities and turned out to be cases of Fabry disease.The purpose of presenting this case is to highlight the fact that suspicion of Fabry disease in patients presenting with these symptoms will lead to early diagnosis and treatment of this condition before occurrences of complications. A 14-year-old male presented with severe burning pain in both hands and feet since last 4 yrs which persisted despite consumption of painkillers and becoming more disabling and without having any family history for such condition. On general examination patient had small reddish coloured lesions around the umbilicus, appearing like angiokeratomas. Skin biopsy confirmed the lesion. On enzyme assay his alpha galactosidase activity found to be '0' nmol/hr/mg of protein, confirming his diagnosis. Patient's creatinine and 2 D ECHO were normal and urine had 1+ proteinuria. Patient started on carbamazepine tablets for pain and referred to higher centre for genetic diagnosis and enzyme replacement therapy. CASE REPORT 2: An 18-year-old male referred to our hospital by general practitioner for fatigue and pedal oedema with deranged renal function tests. On history taking patient gave history of severe burning pain in both hands and feet since age of 9 yrs. Patient's general examination revealed hypertension with pallor, pedal oedema along with angiokeratomas in bathing suit distribution. Patient's ultrasonography of kidney revealed bilaterally normal sized kidneys with altered echotexture and urine examination showed fine granular foamy cells with sub nephrotic range proteinuria. 2 D ECHO revealed concentric left ventricular hypertrophy. Skin biopsy report supported the diagnosis of Fabry disease. Patient advised to undergo renal biopsy to confirm Fabry nephropathy but patient denied any further diagnostic workup for nephropathy or Fabry disease. Patient started on conservative treatment and carbamazepine in renal dose

    To evaluate the diagnostic performance of magnetic resonance (MR) imaging-estimated proton density fat fraction (PDFF) for assessing hepatic steatosis in nonalcoholic fatty liver disease (NAFLD) by using centrally scored histopathologic validation as the reference standard. This prospectively designed, cross-sectional, internal review board-approved, HIPAA-compliant study was conducted in 77 patients who had NAFLD and liver biopsy. MR imaging-PDFF was estimated from magnitude-based low flip angle multiecho gradient-recalled echo images after T2* correction and multifrequency fat modeling. Histopathologic scoring was obtained by consensus of the Nonalcoholic Steatohepatitis (NASH) Clinical Research Network Pathology Committee. Spearman correlation, additivity and variance stabilization for regression for exploring the effect of a number of potential confounders, and receiver operating characteristic analyses were performed. Liver MR imaging-PDFF was systematically higher, with higher histologic steatosis grade (P steatosis grade (ρ = 0.69, P steatosis grade 0 (n = 5) from those with grade 1 or higher (n = 72), 0.825 (95% confidence interval: 0.734, 0.915) to distinguish those with grade 1 or lower (n = 31) from those with grade 2 or higher (n = 46), and 0.893 (95% confidence interval: 0.809, 0.977) to distinguish those with grade 2 or lower (n = 58) from those with grade 3 (n = 19). MR imaging-PDFF showed promise for assessment of hepatic steatosis grade in patients with NAFLD. For validation, further studies with larger sample sizes are needed. © RSNA, 2013.

    Full Text Available Introduction: Decreased oral intake or impaired function / structure in the gut, such as hypertension port associated with atrophic changes in the protein nutrition - calories can lead to micronutrient deficiencies.This paper examines the status of micronutrients in chronic liver disease in children.   Materials and Methods: In this review study databases including proquest, pubmedcentral, scincedirect, ovid, medlineplus were been searched with keyword words such as” chronic liver disease"” minerals””children” between 1999 to 2014. Finally, 3 related articles have been found.   Results: In chronic liver disease changes in micronutrient metabolism lead to changes in the daily requirements, such that in certain circumstances intake increasing or decreasing  is needed. Low serum calcium and phosphate concentrations are often the reflection of malabsorption-induced bone disease that is unresponsive to vitamin D store normalization. Iron is usually deficient in children with CLD and supplementation frequently needed. The origin of iron deficiency is multifactorial and includes ongoing losses, inadequate intakes, serial blood draws and malabsorption secondary to hypertensive enteropathy. Zinc plays an important role in cognitive function, appetite and taste, immune function, wound healing, and protein metabolism. Low plasma zinc levels are frequent in children with chronic cholestasis, but unfortunately plasma concentrations are not reflective of total body zinc status. Copper and manganese, unlike other minerals, are increased in CLD, because they are normally excreted through bile. Parenteral nutrition in cholestatic patients can induce manganese intoxication and accumulation in basal ganglia.   Conclusion:  In fants with CLD are prone to multiple nutritional deficiencies. Mineral state should be evaluated, treated and reevaluated, until sufficient daily requirement achieved. Poster  Presentation, N 33  

  9. Circulating extracellular vesicles with specific proteome and liver microRNAs are potential biomarkers for liver injury in experimental fatty liver disease.

    Directory of Open Access Journals (Sweden)

    Davide Povero

    Full Text Available Nonalcoholic fatty liver disease (NAFLD is the most common chronic liver disease in both adult and children. Currently there are no reliable methods to determine disease severity, monitor disease progression, or efficacy of therapy, other than an invasive liver biopsy.Choline Deficient L-Amino Acid (CDAA and high fat diets were used as physiologically relevant mouse models of NAFLD. Circulating extracellular vesicles were isolated, fully characterized by proteomics and molecular analyses and compared to control groups. Liver-related microRNAs were isolated from purified extracellular vesicles and liver specimens.We observed statistically significant differences in the level of extracellular vesicles (EVs in liver and blood between two control groups and NAFLD animals. Time-course studies showed that EV levels increase early during disease development and reflect changes in liver histolopathology. EV levels correlated with hepatocyte cell death (r2 = 0.64, p<0.05, fibrosis (r2 = 0.66, p<0.05 and pathological angiogenesis (r2 = 0.71, p<0.05. Extensive characterization of blood EVs identified both microparticles (MPs and exosomes (EXO present in blood of NAFLD animals. Proteomic analysis of blood EVs detected various differentially expressed proteins in NAFLD versus control animals. Moreover, unsupervised hierarchical clustering identified a signature that allowed for discrimination between NAFLD and controls. Finally, the liver appears to be an important source of circulating EVs in NAFLD animals as evidenced by the enrichment in blood with miR-122 and 192--two microRNAs previously described in chronic liver diseases, coupled with a corresponding decrease in expression of these microRNAs in the liver.These findings suggest a potential for using specific circulating EVs as sensitive and specific biomarkers for the noninvasive diagnosis and monitoring of NAFLD.

    2017-12-01

    As the number of individuals with non-alcoholic fatty liver disease (NAFLD) has increased, the influence of NAFLD on other metabolic diseases has been highlighted. Accumulating epidemiologic evidence indicates that NAFLD not only affects the liver but also increases the risk of extra-hepatic diseases such as type 2 diabetes mellitus, metabolic syndrome, dyslipidemia, hypertension, cardiovascular or cerebrovascular diseases, and chronic kidney disease. Non-alcoholic steatohepatitis, an advanced type of NAFLD, can aggravate these inter-organ relationships and lead to poorer outcomes. NAFLD induces insulin resistance and exacerbates systemic chronic inflammation and oxidative stress, which leads to organ dysfunction in extra-hepatic tissues. Although more research is needed to identify the pathophysiological mechanisms and causal relationship between NAFLD and cardiometabolic and renal diseases, screening for heart, brain, and kidney diseases, risk assessment for diabetes, and a multidisciplinary approach for managing these patients should be highly encouraged.

  11. Laboratory testing in management of patients with suspected Ebolavirus disease: infection control and safety.

    Gilbert, G L

    2015-08-01

    If routine laboratory safety precautions are followed, the risk of laboratory-acquired infection from handling specimens from patients with Ebolavirus disease (EVD) is very low, especially in the early 'dry' stage of disease. In Australia, border screening to identify travellers returning from EVD-affected west African countries during the 2014-2015 outbreak has made it unlikely that specimens from patients with unrecognised EVD would be sent to a routine diagnostic laboratory. Australian public health and diagnostic laboratories associated with hospitals designated for the care of patients with EVD have developed stringent safety precautions for EVD diagnostic and other tests likely to be required for supportive care of the sickest (and most infectious) patients with EVD, including as wide a range of point-of-care tests as possible. However, it is important that the stringent requirements for packaging, transport and testing of specimens that might contain Ebolavirus--which is a tier 1 security sensitive biology agent--do not delay the diagnosis and appropriate management of other potentially serious but treatable infectious diseases, which are far more likely causes of a febrile illness in people returning from west Africa. If necessary, urgent haematology, biochemistry and microbiological tests can be performed safely, whilst awaiting the results of EVD tests, in a PC-2 laboratory with appropriate precautions including: use of recommended personal protective equipment (PPE) for laboratory staff; handling any unsealed specimens in a class 1 or II biosafety cabinet; using only centrifuges with sealed rotors; and safe disposal or decontamination of all used equipment and laboratory waste.

    Nonalcoholic fatty liver disease (NAFLD) is one of the most important causes of liver-related morbidity and mortality in children. Recently, we have reported the effects of docosahexaenoic acid (DHA), the major dietary long-chain polyunsaturated fatty acids, in children with NAFLD. DHA exerts a potent anti-inflammatory activity through the G protein-coupled receptor (GPR)120. Our aim was to investigate in pediatric NAFLD the mechanisms underlying the effects of DHA administration on histo-pathological aspects, GPR120 expression, hepatic progenitor cell activation and macrophage pool. 20 children with untreated NAFLD were included. Children were treated with DHA for 18 months. Liver biopsies before and after the treatment were analyzed. Hepatic progenitor cell activation, macrophage pool and GPR120 expression were evaluated and correlated with clinical and histo-pathological parameters. GPR120 was expressed by hepatocytes, liver macrophages, and hepatic progenitor cells. After DHA treatment, the following modifications were present: i) the improvement of histo-pathological parameters such as NAFLD activity score, ballooning, and steatosis; ii) the reduction of hepatic progenitor cell activation in correlation with histo-pathological parameters; iii) the reduction of the number of inflammatory macrophages; iv) the increase of GPR120 expression in hepatocytes; v) the reduction of serine-311-phosphorylated nuclear factor kappa B (NF-κB) nuclear translocation in hepatocytes and macrophages in correlation with serum inflammatory cytokines. DHA could modulate hepatic progenitor cell activation, hepatocyte survival and macrophage polarization through the interaction with GPR120 and NF-κB repression. In this scenario, the modulation of GPR120 exploits a novel crucial role in the regulation of the cell-to-cell cross-talk that drives inflammatory response, hepatic progenitor cell activation and hepatocyte survival.

    Alms1 mutant (foz/foz) mice develop hyperphagic obesity, diabetes, metabolic syndrome, and fatty liver (steatosis). High-fat (HF) feeding converts pathology from bland steatosis to nonalcoholic steatohepatitis (NASH) with fibrosis, which leads to cirrhosis in humans. We sought to establish how dietary composition contributes to NASH pathogenesis. foz/foz mice were fed HF diet or chow 24 weeks, or switched HF to chow after 12 weeks. Serum ALT, NAFLD activity score (NAS), fibrosis severity, neutrophil, macrophage and apoptosis immunohistochemistry, uncoupling protein (UCP)2, ATP, NF-κB activation/expression of chemokines/adhesion molecules/fibrogenic pathways were determined. HF intake upregulated liver fatty acid and cholesterol transporter, CD36. Dietary switch expanded adipose tissue and decreased hepatomegaly by lowering triglyceride, cholesterol ester, free cholesterol and diacylglyceride content of liver. There was no change in lipogenesis or fatty acid oxidation pathways; instead, CD36 was suppressed. These diet-induced changes in hepatic lipids improved NAS, reduced neutrophil infiltration, normalized UCP2 and increased ATP; this facilitated apoptosis with a change in macrophage phenotype favoring M2 cells. Dietary switch also abrogated NF-κB activation and chemokine/adhesion molecule expression, and arrested fibrosis by dampening stellate cell activation. Reversion to a physiological dietary composition after HF feeding in foz/foz mice alters body weight distribution but not obesity. This attenuates NASH severity and fibrotic progression by suppressing NF-κB activation and reducing neutrophil and macrophage activation. However, adipose inflammation persists and is associated with continuing apoptosis in the residual fatty liver disease. Taken together, these findings indicate that other measures, such as weight reduction, may be required to fully reverse obesity-related NASH. Copyright © 2013 The Obesity Society.

    2013-01-01

    Viral hepatitis is among the important health problems in Egypt which lead to chronic hepatitis and liver cirrhosis.Liver cirrhosis is associated with circulatory disturbances which are attributed to arterial vasodilatation that results from overproduction or reduced degradation of vasodilator substances. Adrenomedullin (AM) is responsible for the arteriolar vasodilatation and hyper dynamic circulation in liver cirrhosis. The aim of work was to the assessment patients with chronic hepatitis and liver cirrhosis with or without renal impairment by determining the level of AM and comparing them with healthy controls. 44 patients with chronic liver diseases (14 patients with chronic hepatitis and 30 patients with liver cirrhosis, 16 in Child-Pugh's class A, 8 in Child-Pugh's class B, and 6 in Child-Pugh's class C) were examined clinically, laboratory, ultrasonography and endoscopically. Plasma concentration of adrenomedullin was measured in all patients and 15 normal controls.The mean levels of AM were higher in patients with chronic hepatitis and patients with liver cirrhosis compared to controls (0.52 ± 0.19 ng/ml , 0.67 ± 0.16 ng/ml and 0.35 ± 0.12 ng/ml, respectively; p<0.001). The mean levels of plasma aldosterone concentration were higher in patients with chronic hepatitis and patients with liver cirrhosis compared to controls (256 ± 197 ng/dl 358 ± 264 ng/dl and 179 ± 142 ng/dl, respectively; p<0.001). The mean levels of creatinine clearance were lower in patients with chronic hepatitis and patients with liver cirrhosis compared to controls (0.31±0.19 ml/min 0.25±0.21 ml/min and 0.45±0.37 ml/min, respectively; p<0.001). The mean levels of AM were higher in patients with liver cirrhosis with renal impairment than without. Also there was significant difference in AM levels between patients with and without esophageal varices (0.71 ± 0.22 ng/ml and 0.52 ± 0.17 ng/ml respectively, p<0.05).

    Full Text Available Systematic search of bibliographic databases was conducted to describe the prevalence of dietary supplement use in cardiac patients. Included for review were studies that investigated supplement use in people with cardiovascular risk factors or proven cardiovascular disease. Databases searched were Medline, EMBASE, CINAHL, AMED, Meditext, H&S and IPA. Over five hundred articles were retrieved and twenty studies met the criteria for this review. Dietary supplements were taken by a median 36% (interquartile range: 26–42% of cardiac patients; 36% (IQR 18–43% reported taking a vitamin/mineral supplement and 12% (IQR 7–21% used herbal supplements. Many users indicated that supplements were taken specifically for heart health and 16–64% of users reported using supplements alongside prescription medications. However 39–95% of treating physicians were unaware of patients’ supplement use. Dietary supplement use in patients with cardiovascular disease appears common, as does the concurrent use of supplements with prescription medicines. This information is often not communicated to doctors and treating physicians may need to be more proactive in asking about supplement use.

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

    Twenty seven cases of acute hepatitis 120 of chronic hepatitis 133 of liver cirrhosis 79 of fatty liver 28 of alcoholic liver injury 5 of intrahepatic cholestasis 22 of obstructive jaundice and 100 normal adults were studied. EMI CT 5005 whole body scanner was used to obtain scan of the liver and spleen, and CT number of them was measured in EMI units, so L/S ratio was calculated by dividing both EMI number. In the patients with obesity, the EMI number of the liver and/or spleen were higher than normal controls. In acute hepatitis, EMI number of the liver, spleen and L/S ratio were no significant differences compared with controls. In chronic hepatitis inactive and active type, EMI number of the liver and spleen were no significant differences between chronic hepatitis and controls, but L/S ratio was lower than that of controls. In cirrhosis of the liver, EMI number of the liver and L/S ratio were lower than that of controls, but EMI number of the spleen had no significant differences compared with controls. In patients with fatty liver, EMI number of the liver and L/S ratio were lower than any other diffuse liver diseases. In alcoholic liver injury had no significant differences from normal controls in liver EMI number, spleen EMI number and L/S ratio. In intrahepatic cholestsis, there was weak inverse corelation between liver EMI number and serum total bilirubin, and in obstructive jaundice strong inverse corelation was seen. In diffuse liver diseases, fatty infiltration, liver cell necrosis, fibrosis or jaundice may decrease the EMI number of the liver and/or L/S ratio, but except for fatty liver, it seems difficult to diagnose the diffuse liver diseases by CT scanner.

    Outbreaks of viral haemorrhagic fevers such as Ebola can lead to imported cases in Europe and America. The eventuality of surgery in the setting of Ebola Virus Disease (EVD) is low, but the Spanish Association of Surgeons elaborated a surgical protocol for EVD. Elective surgical procedures are not indicated. Emergency cases can be considered in: persons under investigation, possible cases and early confirmed cases. In some conditions usually treated by surgery a medical treatment can be tested. All cases must be treated in high technology hospitals. These hospitals must be equipped with adequate means for healthcare provider's protection. All members of the healthcare team should practice thorough simulation prior to caring for a possible Ebola patient. This protocol is based on international guidelines on use of Personal Protective Equipment, protocols of other scientific societies, and specific recommendations for the operating room environment.

    2017-08-01

    Despite advances in treatment of alcohol use disorders that focus on increasing abstinence and reducing recidivism, alcoholic liver disease (ALD) is projected to be the major cause of cirrhosis and its complications. Malnutrition is recognized as the most frequent complication in ALD, and despite the high clinical significance, there are no effective therapies to reverse malnutrition in ALD. Malnutrition is a relatively imprecise term, and sarcopenia or skeletal muscle loss, the major component of malnutrition, is primarily responsible for the adverse clinical consequences in patients with liver disease. It is, therefore, critical to define the specific abnormality (sarcopenia) rather than malnutrition in ALD, so that therapies targeting sarcopenia can be developed. Skeletal muscle mass is maintained by a balance between protein synthesis and proteolysis. Both direct effects of ethanol (EtOH) and its metabolites on the skeletal muscle and the consequences of liver disease result in disturbed proteostasis (protein homeostasis) and consequent sarcopenia. Once cirrhosis develops in patients with ALD, abstinence is unlikely to be effective in completely reversing sarcopenia, as other contributors including hyperammonemia, hormonal, and cytokine abnormalities aggravate sarcopenia and maintain a state of anabolic resistance initiated by EtOH. Cirrhosis is also a state of accelerated starvation, with increased gluconeogenesis that requires amino acid diversion from signaling and substrate functions. Novel therapeutic options are being recognized that are likely to supplant the current "deficiency replacement" approach and instead focus on specific molecular perturbations, given the increasing availability of small molecules that can target specific signaling components. Myostatin antagonists, leucine supplementation, and mitochondrial protective agents are currently in various stages of evaluation in preclinical studies to prevent and reverse sarcopenia, in cirrhosis in

    The purpose of this study was to investigate the chronological relationship between scan delay and liver enhancement for the hepatobiliary phase on Gd-EOB-DTPA-enhanced MRI and evaluate the effects of liver function on liver enhancement. Hepatobiliary-phase images were retrospectively evaluated in 125 patients with chronic liver disease. Hepatobiliary phase images were obtained at 5, 10, 15, and 20 min after injection. We calculated relative liver enhancement (RLE) at t min after injection by dividing the signal intensity (SI) of the liver at t min by precontrast SI. We compared RLE values at 5, 10, 15, and 20 min and evaluated the detectability of focal hepatic lesions. We analyzed the effect of liver function on RLE with the generalized linear model. There was not significant difference in RLE and lesion detectability at 15 and 20 min. RLE in the Child-Pugh C group was significantly lower than in the Child-Pugh A and B groups. The serum albumin level and prothrombin time were significantly correlated with the liver enhancement. A delay time of 15 min for the hepatobiliary phase was thought to be adequate in patients with mild liver dysfunction. The serum albumin level and prothrombin time would be predictive of liver enhancement in the hepatobiliary phase. (author)

  5. Origins of Portal Hypertension in Nonalcoholic Fatty Liver Disease.

    Science.gov (United States)

    Baffy, Gyorgy

    2018-03-01

    Nonalcoholic fatty liver disease (NAFLD) advanced to cirrhosis is often complicated by clinically significant portal hypertension, which is primarily caused by increased intrahepatic vascular resistance. Liver fibrosis has been identified as a critical determinant of this process. However, there is evidence that portal venous pressure may begin to rise in the earliest stages of NAFLD when fibrosis is far less advanced or absent. The biological and clinical significance of these early changes in sinusoidal homeostasis remains unclear. Experimental and human observations indicate that sinusoidal space restriction due to hepatocellular lipid accumulation and ballooning may impair sinusoidal flow and generate shear stress, increasingly disrupting sinusoidal microcirculation. Sinusoidal endothelial cells, hepatic stellate cells, and Kupffer cells are key partners of hepatocytes affected by NAFLD in promoting endothelial dysfunction through enhanced contractility, capillarization, adhesion and entrapment of blood cells, extracellular matrix deposition, and neovascularization. These biomechanical and rheological changes are aggravated by a dysfunctional gut-liver axis and splanchnic vasoregulation, culminating in fibrosis and clinically significant portal hypertension. We may speculate that increased portal venous pressure is an essential element of the pathogenesis across the entire spectrum of NAFLD. Improved methods of noninvasive portal venous pressure monitoring will hopefully give new insights into the pathobiology of NAFLD and help efforts to identify patients at increased risk for adverse outcomes. In addition, novel drug candidates targeting reversible components of aberrant sinusoidal circulation may prevent progression in NAFLD.

    Full Text Available The aim of this study was to investigate the hepatoprotective effects of resveratrol in alcoholic liver disease (ALD. Alcohol was administered to healthy female rats starting from 6% (v/v and gradually increased to 20% (v/v by the fifth week. After 16 weeks of intervention, liver enzymes (aspartate aminotransferase [AST] and alanine aminotransferase [ALT] were analyzed using a chemistry analyzer, while hepatic antioxidant enzymes, oxidative stress markers, and caspase 3 activity were assessed using ELISA kits. Furthermore, hepatic CYP2E1 protein levels and mRNA levels of antioxidant and inflammation-related genes were determined using western blotting and RT-PCR, respectively. The results showed that resveratrol significantly attenuated alcohol-induced elevation of liver enzymes and improved hepatic antioxidant enzymes. Resveratrol also attenuated alcohol-induced CYP2E1 increase, oxidative stress, and apoptosis (caspase 3 activity. Moreover, genes associated with oxidative stress and inflammation were regulated by resveratrol supplementation. Taken together, the results suggested that resveratrol alleviated ALD through regulation of oxidative stress, apoptosis, and inflammation, which was mediated at the transcriptional level. The data suggests that resveratrol is a promising natural therapeutic agent against chronic ALD.

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

    The ability of exercise-induced myocardial hypoperfusion on thallium scintigraphy to predict coronary events was assessed in 1,689 patients with symptoms suggestive of coronary artery disease but without prior myocardial infarction or coronary artery bypass surgery. A total of 74 patients had a coronary event in the year after testing (12 cardiac deaths, 20 nonfatal infarctions and 42 referrals for bypass surgery more than 60 days after testing). Stepwise logistic regression identified only three independent predictors: the number of myocardial regions with reversible hypoperfusion (an index of the extent of hypoperfusion), the maximal magnitude of hypoperfusion (an index of the severity of hypoperfusion) and the achieved heart rate (an index of exercise performance). Both extent and severity were exponentially correlated with event rate (r greater than 0.97 and p less than 0.01 for each), whereas achieved heart rate was linearly correlated with event rate (r = 0.79 and p less than 0.05). On the basis of these data, a prognostic model was defined that employs extent and severity as stress-dependent orthogonal variables. Using this model, the predicted coronary event rate ranged over two orders of magnitude--from a low of 0.4% in patients able to exercise adequately without developing severe and extensive hypoperfusion at a low heart rate (less than 85% of their maximal predicted heart rate). Extent and severity of myocardial hypoperfusion, therefore, are important independent variables of prognosis in patients with suspected coronary artery disease

    While exercise thallium imaging has improved sensitivity and specificity for detection of coronary artery disease (CAD), its predictive value for morbid cardiac events is unclear. Of 532 consecutive patients who underwent exercise thallium imaging, follow-up was complete in 515 (97%) after an average of 36 months (range 31 to 48). Two hundred six patients had an abnormal exercise thallium response and 309 had a normal response. Twenty morbid cardiac events occurred (13 deaths and 7 acute myocardial infarctions [AMI]). Of the 13 patients who died, 12 had abnormal thallium results. Overall, 5.8% of the patients with abnormal thallium results died, in contrast to 0.3% of patients with normal results. Of the 7 patients who had a nonfatal AMI, 3 had abnormal exercise thallium results. Moreover, similar proportions of patients (1.4% and 1.3%) with normal and abnormal exercise thallium results had nonfatal AMI. Presence or absence of pathologic Q waves and inclusion of exercise electrocardiographic results did not significantly alter the results. Thus, although a normal exercise thallium response significantly reduces the likelihood of cardiovascular death, its predictive value for nonfatal AMI is limited. Moreover, the relatively low event rate for patients with a positive exercise thallium response further limits its prognostic value

    Malnutrition is associated with alcoholic liver disease (ALD) and related complications such as hepatic encephalopathy and increased rate of infections. Avoidance of prolonged fasting and overly restrictive diets is important to avoid poor nutrition. Adequate intake of calories, protein, and micronutrients via frequent small meals and evening supplements and/or enteral and parenteral nutrition when indicated has been associated with reduced mortality and morbidity in patients with ALD. Modification of protein/fat sources and composition in addition to probiotic supplementation are promising interventions for decreased progression of ALD and its complications.

    Full Text Available Background. Fatty liver index (FLI and lipid accumulation product (LAP are indexes originally designed to assess the risk of fatty liver and cardiovascular disease, respectively. Both indexes have been proven to be reliable markers of subsequent metabolic syndrome; however, their ability to predict metabolic syndrome in subjects without fatty liver disease has not been clarified. Methods. We enrolled consecutive subjects who received health check-up services at Taipei Veterans General Hospital from 2002 to 2009. Fatty liver disease was diagnosed by abdominal ultrasonography. The ability of the FLI and LAP to predict metabolic syndrome was assessed by analyzing the area under the receiver operating characteristic (AUROC curve. Results. Male sex was strongly associated with metabolic syndrome, and the LAP and FLI were better than other variables to predict metabolic syndrome among the 29,797 subjects. Both indexes were also better than other variables to detect metabolic syndrome in subjects without fatty liver disease (AUROC: 0.871 and 0.879, resp., and the predictive power was greater among women. Conclusion. Metabolic syndrome increases the cardiovascular disease risk. The FLI and LAP could be used to recognize the syndrome in both subjects with and without fatty liver disease who require lifestyle modifications and counseling.

It is an increasingly recognized condition that has become the most common liver disorder in developed countries, affecting over one-third of the population and is associated with increased cardiovascular- and liver-related mortality. NAFLD is a spectrum of disorders, beginning as simple steatosis. In about 15% of all NAFLD cases, simple steatosis can evolve into non-alcoholic steatohepatitis, a medley of inflammation, hepatocellular injury, and fibrosis, often resulting in cirrhosis and even hepatocellular cancer. However, the molecular mechanism underlying NAFLD progression is not completely understood. Its pathogenesis has often been interpreted by the "double-hit" hypothesis. The primary insult or the "first hit" includes lipid accumulation in the liver, followed by a "second hit" in which proinflammatory mediators induce inflammation, hepatocellular injury, and fibrosis. Nowadays, a more complex model suggests that fatty acids (FAs and their metabolites may be the true lipotoxic agents that contribute to NAFLD progression; a multiple parallel hits hypothesis has also been suggested. In NAFLD patients, insulin resistance leads to hepatic steatosis via multiple mechanisms. Despite the excess hepatic accumulation of FAs in NAFLD, it has been described that not only de novo FA

    Purpose: To determine the prevalence of clinically relevant non-inflammatory disease on MRI of the sacroiliac (SI) joints in patients suspected of sacroiliitis. To assess the added value of axial imaging of the pelvis in these patients. Methods: In a retrospective study of 691 patients undergoing MRI of the SI joints from January 2006 to December 2012 for inflammatory back pain the prevalence of sacroiliitis and non-inflammatory disease was recorded. Results: In 285 (41%) patients MRI did not show any abnormal findings. In 36% of patients MRI features of sacroiliitis were present. Spinal degenerative changes were the most common non-inflammatory finding in 305 patients (44.1%) and consisted of disc degeneration in 222 (32%) patients, facet joint arthrosis in 58 (8.4%) patients and disc herniation in 25 (3.6%) patients. Hip joint disease in 44 (6.4%) patients, lumbosacral transitional anomaly in 41 (5.9%) patients, SI joint degenerative changes in 25 (3.6%) patients and diffuse idiopathic skeletal hyperostosis in 24 (3.5%) patients were also common. Osteitis condensans ilii in 17 (2.5%) patients, tumour in 11 (1.6%) patients, fracture in 8 (1.2%) patients, infection in 4 (0.6%) patients and acute spondylolysis in 2 patients (0.3%) were less frequently seen. Conclusion: Our study shows that non-inflammatory disease is more common than true sacroiliitis on MRI of the SI joints in patients with inflammatory type back pain. Axial pulse sequences may demonstrate unexpected findings that remain undetected if only coronal images are obtained. Clinical relevance statement:, MRI of the SI joints may demonstrate conditions that clinically mimic sacroiliitis. Axial imaging of the pelvis may help detect these unexpected findings.

    A 3-year-old boy was admitted to our hospital because of macrocephaly and developmental delay of motor function. He was the first son of non-consanguineous healthy parents. All other family members were normal. The increase of head circumference was first noted at 6 months of age. He could not walk until 1 1/2 years old. He had febrile convulsions at 1 1/2 and 2 years old. On admission (3 y 10 mo), his head circumference was 55.8 cm (more than 98th percentile). Intelligence was normal for his age. Neurological examination revealed ataxic-spastic gait and generalized hyperreflexia with bilateral ankle clonus. He could not run, or stand on one foot. Sensation was normal. CT scan showed diffuse low density areas in cerebral white matter, especially in frontal lobes. Ventricular systems were of normal size. Leukocyte lysosomal enzyme activities, blood and urinary amino acid analysis, the amount of very long chain fatty acids in plasma sphingomyelin, blood gas analysis, and organic acid levels in urine were all within normal range. Electroencephalogram, auditory-evoked response, nerve conduction velocities, and cerebrospinal fluid examination were also normal. The diagnosis of Alexander's disease was most likely. However, this case was atypical, in that his mental development was quite normal, and that regression of his motor activities was not noted so far. Magnetic resonance imaging (spin-echo image) revealed widespread abnormal signal intensity areas corresponding to the low densities shown by CT, where both T 1 and T 2 relaxation times were prolonged, suggesting the increase of free water content in the affected white matter. These changes were localized in cerebral white matter and more prominent in frontal lobes. On the other hand, the white matter of cerebellum and brain stem, internal capsule, and anterior commisure looked normal. (J.P.N.)

    While immunohistochemistry (IHC) methods have been widely conducted for the diagnosis of Hirschsprung disease (HSCR) in developed countries, there are very few studies on their use in developing countries where hematoxylin and eosin (HE) staining is a key element of the diagnosis of HSCR. We aimed to determine the accuracy of HE staining in the diagnosis of HSCR using S100 IHC as the reference standard in Indonesia. All histopathology performed for the suspicion of HSCR patients from January 2013 to August 2015 in Dr. Sardjito Hospital, Yogyakarta, Indonesia, were retrospectively reviewed. Our study included 23 HSCR patients: 9 males and 14 females. The HE staining revealed 14 negative (absence of ganglion cells) cases (61%) and 9 positive (presence of ganglion cells) cases (39%). In S100 IHC, out of the 9 positive cases by HE staining, 6 (67%) were confirmed for having ganglion cells; and out of the 14 negative cases by HE staining, 12 (86%) were reported negative and 2 (14%) were positive by S100 IHC staining. The sensitivity, specificity, positive predictive value, negative predictive value, and accuracy rates of the HE staining were 80% (95% CI: 0.51-0.95), 75% (95% CI: 0.36-0.96), 85.7% (95% CI: 0.56-0.98), 66.7% (95% CI: 0.31-0.91), and 78.3% (95% CI: 0.58-0.90), respectively. Our study showed that HE staining has relatively moderate accuracy for the diagnosis of HSCR. The use of HE staining is still recommended for the diagnosis of HSCR given the limitation of resource allocation for more expensive IHC technologies in developing countries.

    Non-alcoholic fatty liver disease (NAFLD) is the most common cause of chronic liver disease in children. The gold standard for diagnosis is liver biopsy. MRI is a non-invasive imaging method to provide quantitative measurement of hepatic fat content. The methodology is particularly appealing for the pediatric population because of its rapidity and radiation-free imaging techniques. To develop a multi-point Dixon MRI method with multi-interference models (multi-fat-peak modeling and bi-exponential T2* correction) for accurate hepatic fat fraction (FF) and T2* measurements in pediatric patients with NAFLD. A phantom study was first performed to validate the accuracy of the MRI fat fraction measurement by comparing it with the chemical fat composition of the ex-vivo pork liver-fat homogenate. The most accurate model determined from the phantom study was used for fat fraction and T2* measurements in 52 children and young adults referred from the pediatric hepatology clinic with suspected or identified NAFLD. Separate T2* values of water (T2*W) and fat (T2*F) components derived from the bi-exponential fitting were evaluated and plotted as a function of fat fraction. In ten patients undergoing liver biopsy, we compared histological analysis of liver fat fraction with MRI fat fraction. In the phantom study the 6-point Dixon with 5-fat-peak, bi-exponential T2* modeling demonstrated the best precision and accuracy in fat fraction measurements compared with other methods. This model was further calibrated with chemical fat fraction and applied in patients, where similar patterns were observed as in the phantom study that conventional 2-point and 3-point Dixon methods underestimated fat fraction compared to the calibrated 6-point 5-fat-peak bi-exponential model (P fat fraction, T2*W (27.9 ± 3.5 ms) decreased, whereas T2*F (20.3 ± 5.5 ms) increased; and T2*W and T2*F became increasingly more similar when fat fraction was higher than 15-20%.

    The fact there are increase of intrapulmonary arteriovenous shunt amount in the liver cirrhosis patient has been known since 1950. And the method of shunt amount calculation by radionuclide method using 99m Tc-MAA was introduced in the middle of 1970. We measured intrapulmonary shunt amount by means of perfusion lung scan using 99m Tc-MAA in the various type of liver diseases especially in chronic liver diseases and acute liver disease. The results were as followed. 1) The amount of arteriovenous intrapulmonary shunt in the total case of liver disease was 9.3±3.9%, and that of in the control group was 4.6±2.1%. 2) The amount of arteriovenous intrapulmonary shunt in the chronic liver disease was 10.8±4.4%, and that of in the acute liver disease was 7.2±2.8%. We observed significant differences between normal control group and liver disease group, and between chronic liver disease group and acute liver disease group in the amount of shunt by the nucleolide method.

    Liver abnormalities that normalize during infancy as well an enteropathy are reported in Shwachman-Diamond syndrome (SDS). The pathogenesis of both conditions is unknown. We report two SDS cases with autoimmune-like (antismooth muscle and/or antinuclear antibody positivity) liver disease and antigliadin antibody positive inflammatory enteropathy. Hypertransaminasemia did not resolve after immunosuppressive therapy and/or a gluten-free diet. These transient autoimmune phenomena and gut-liver axis perturbations may have played a role in transient SDS hepatopathy and enteropathy. Our report may stimulate other studies to define the relationship between the SDS genetic defect and intestinal permeability as the pathogenic mechanism underlying SDS related liver and intestinal inflammation.

    2015-09-01

    Disparities in health reflect the differences in the incidence, prevalence, burden of disease and access to care determined by socio-economic and environmental factors. With liver disease, these disparities are exacerbated by a combination of limited awareness and preventable causes of morbidity and mortality in addition to the diagnostic and management costs. Sub-Saharan Africa, comprising 11% of the world's population, disproportionately has 24% of the global disease burden, yet allocates health. It has 3% of the global healthcare workforce with a mean of 0.8 healthcare workers per 1000 population. Barriers to healthcare access are many and compounded by limited civil registration data, socio-economic inequalities, discrepancies in private and public healthcare services and geopolitical strife. The UN 2014 report on the Millennium Development Goals suggest that sub-Saharan Africa will probably not meet several goals, however with HIV/AIDS and Malaria (goal 6), many successes have been achieved. A 2010 Global Burden of Disease study demonstrated that cirrhosis mortality in sub-Saharan Africa doubled between 1980 and 2010. Aetiologies included hepatitis B (34%), hepatitis C (17%), alcohol (18%) and unknown in 31%. Hepatitis B, C and alcohol accounted for 47, 23 and 20% of hepatocellular carcinoma respectively. In 10%, the underlying aetiology was not known. Liver disease reflects the broader disparities in healthcare in sub-Saharan Africa. However, many of these challenges are not insurmountable as vaccines and new therapies could comprehensively deal with the burden of viral hepatitis. Access to and affordability of therapeutics remains the major barrier. © 2015 John Wiley & Sons A/S. Published by John Wiley & Sons Ltd.

  5. Does Vitamin C Deficiency Promote Fatty Liver Disease Development?

    Full Text Available Obesity and the subsequent reprogramming of the white adipose tissue are linked to human disease-complexes including metabolic syndrome and concurrent non-alcoholic fatty liver disease (NAFLD and non-alcoholic steatohepatitis (NASH. The dietary imposed dyslipidemia promotes redox imbalance by the generation of excess levels of reactive oxygen species and induces adipocyte dysfunction and reprogramming, leading to a low grade systemic inflammation and ectopic lipid deposition, e.g., in the liver, hereby promoting a vicious circle in which dietary factors initiate a metabolic change that further exacerbates the negative consequences of an adverse life-style. Large epidemiological studies and findings from controlled in vivo animal studies have provided evidence supporting an association between poor vitamin C (VitC status and propagation of life-style associated diseases. In addition, overweight per se has been shown to result in reduced plasma VitC, and the distribution of body fat in obesity has been shown to have an inverse relationship with VitC plasma levels. Recently, a number of epidemiological studies have indicated a VitC intake below the recommended daily allowance (RDA in NAFLD-patients, suggesting an association between dietary habits, disease and VitC deficiency. In the general population, VitC deficiency (defined as a plasma concentration below 23 μM affects around 10% of adults, however, this prevalence is increased by an adverse life-style, deficiency potentially playing a broader role in disease progression in specific subgroups. This review discusses the currently available data from human surveys and experimental models in search of a putative role of VitC deficiency in the development of NAFLD and NASH.

    Nonalcoholic fatty liver disease (NAFLD) is the most common chronic liver disease in children. In order to advance the field of NAFLD, noninvasive imaging methods for measuring liver fat are needed. Advanced magnetic resonance imaging (MRI) has shown great promise for the quantitative assessment of hepatic steatosis but has not been validated in children. Therefore, this study was designed to evaluate the correlation and diagnostic accuracy of MRI-estimated liver proton density fat fraction (PDFF), a biomarker for hepatic steatosis, compared to histologic steatosis grade in children. The study included 174 children with a mean age of 14.0 years. Liver PDFF estimated by MRI was significantly (P steatosis grade. The correlation of MRI-estimated liver PDFF and steatosis grade was influenced by both sex and fibrosis stage. The correlation was significantly (P steatosis and mild steatosis ranged from 0.69 to 0.82. The overall accuracy of predicting the histologic steatosis grade from MRI-estimated liver PDFF was 56%. No single threshold had sufficient sensitivity and specificity to be considered diagnostic for an individual child. Advanced magnitude-based MRI can be used to estimate liver PDFF in children, and those PDFF values correlate well with steatosis grade by liver histology. Thus, magnitude-based MRI has the potential for clinical utility in the evaluation of NAFLD, but at this time no single threshold value has sufficient accuracy to be considered diagnostic for an individual child. © 2015 by the American Association for the Study of Liver Diseases.

    Hapatoscintigram has been a useful diagnostic method for the liver disease since 1953, but reasonable diagnostic criteria for parenchymal liver diseases are not yet accurately established. For the purpose of searching for more advanced diagnostic criteria for various types of live diseases by the liver scan, a retrospective study was made of 272 cases who underwent both hepatoscintigram with 198 Au colloid and liver biopsy in Hanyang University Hospital from Jan, 1978 to Dec, 1981. The results were as follows: 1. Fuzzy margin (irregular indentation of the liver margin) in the hepatoscintigram was noted in 226 cases (97.79%) 2. Of 35 cases with fuzzy margin only, 28 cases (80%)revealed mild parenchymal liver disease, such as acute hepatitis or chronic persistent hepatitis by the liver biopsy. 3. Mottling change (209 cases) was always accomplished by fuzzy margin except only one case, and 31 cases (86.1%) of fuzzy and mottling cases (36 cases) showed mild parenchymal liver disease. 4. Configuration change (193 cases) was usually accompanied with other changes and especially 104 cases had configuration changed with fuzzy and mottling changes. 73 cases (88.445) of 86 cases with severe configuration changed revealed advanced parenchymal liver disease on biopsy. If liver scan showed mild configuration change, we could not decide the type of liver disease only liver scan, and so further studies are needed. 5. Splenic uptake was noted 34 cases (40.48%) of 84 cases with advanced parenchymal liver disease, and the degree of splenic uptake was for the most part moderate or severe; whereas splenic uptake was noted in 18 cases (16.51%) of the mild parenchymal liver disease (109 cases), and the degree of splenic uptake was largely mild.

    Full Text Available Background: While open lung biopsy (OLB performed in patients on mechanical ventilation (MV with diffuse lung diseases (DLD can be extremely important in establishing the diagnosis, the associated risk of this procedure should be taken into account. Aim: To determine the diagnostic yield, therapeutic changes, complications and mortality in patients with DLD on MV submitted to OLB. Methods: Retrospective study of 19 patients admitted to S. João Hospital between January 1999 and July 2007 (8.5 years. Data analysed included demographic data, ventilation variables before and after biopsy, diagnostic yield, effect on subsequent treatment changes and complications of OLB. Statistical analysis was performed using SPSS 14.0. Results: The mean age of patients was 58 ± 16.3 years old and 53% were male. The mean duration of hospital stay in Intensive Care Unit before performing OLB was 13 ± 7 days. All biopsies were performed by thoracotomy. The diagnostic yield was 95%. There were no significant differences in partial pressure of arterial oxygen/fraction of inspired oxygen (PaO2/FiO2 ratio and the positive end expiratory pressure (PEEP before and after OLB. Postoperative complications occurred in 4 patients (21%; persistent air leak. Alteration in the diagnosis occurred in 14 patients (74% and in 8 patients (42% there was a modification in the treatment regimen. Global mortality was 47% (9 patients but there were no biopsyrelated deaths. Conclusion: The high diagnostic yield and the low incidence of complications make OLB a useful procedure in patients on MV with DLD of unknown aetiology. However, early OLB may lead to even better results in some patients.

    Epicardial adipose tissue is a source of pro-inflammatory cytokines and has been linked to the development of coronary artery disease. No study has systematically assessed the relationship between local epicardial fat volume (EFV) and myocardial perfusion defects. We analyzed EFV in patients undergoing SPECT myocardial perfusion imaging combined with computed tomography (CT) for attenuation correction. Low-dose CT without contrast was performed in 396 consecutive patients undergoing SPECT imaging for evaluation of coronary artery disease. Regional thickness, cross-sectional areas, and total EFV were assessed. 295 patients had normal myocardial perfusion scans and 101 had abnormal perfusion scans. Mean EFVs in normal, ischemic, and infarcted hearts were 99.8 ± 82.3 cm3, 156.4 ± 121.9 cm3, and 96.3 ± 102.1 cm3, respectively (P < 0.001). Reversible perfusion defects were associated with increased local EFV compared to normal perfusion in the distribution of the right (69.2 ± 51.5 vs 46.6 ± 32.0 cm3; P = 0.03) and left anterior descending coronary artery (87.1 ± 76.4 vs 46.7 ± 40.6 cm3; P = 0.005). Our results demonstrate increased regional epicardial fat in patients with active myocardial ischemia compared to patients with myocardial scar or normal perfusion on nuclear perfusion scans. Our results suggest a potential role for cardiac CT to improve risk stratification in patients with suspected coronary artery disease. PMID:25339129

    Non-alcoholic fatty liver disease encompasses a spectrum of liver diseases, including simple steatosis, steatohepatitis, liver fibrosis and cirrhosis and hepatocellular carcinoma. Non-alcoholic fatty liver disease is currently the most dominant chronic liver disease in Western countries due to the fact that hepatic steatosis is associated with insulin resistance, type 2 diabetes mellitus, obesity, metabolic syndrome and drug-induced injury. A variety of chemicals, mainly drugs, and diets is known to cause hepatic steatosis in humans and rodents. Experimental non-alcoholic fatty liver disease models rely on the application of a diet or the administration of drugs to laboratory animals or the exposure of hepatic cell lines to these drugs. More recently, genetically modified rodents or zebrafish have been introduced as non-alcoholic fatty liver disease models. Considerable interest now lies in the discovery and development of novel non-invasive biomarkers of non-alcoholic fatty liver disease, with specific focus on hepatic steatosis. Experimental diagnostic biomarkers of non-alcoholic fatty liver disease, such as (epi)genetic parameters and ‘-omics’-based read-outs are still in their infancy, but show great promise. . In this paper, the array of tools and models for the study of liver steatosis is discussed. Furthermore, the current state-of-art regarding experimental biomarkers such as epigenetic, genetic, transcriptomic, proteomic and metabonomic biomarkers will be reviewed. PMID:26073454

    The seroepidemiology of Leptospira infection in patients suffering from liver disease has been poorly studied. Information about risk factors associated with infection in liver disease patients may help in the optimal planning of preventive measures. We sought to determine the association of Leptospira IgG seroprevalence and patients with liver diseases, and to determine the characteristics of the patients with Leptospira exposure. We performed a case-control study of 75 patients suffering from liver diseases and 150 age- and gender-matched control subjects. Diagnoses of liver disease included liver cirrhosis, steatosis, chronic hepatitis, acute hepatitis, and amoebic liver abscess. Sera of participants were analyzed for the presence of anti- Leptospira IgG antibodies using a commercially available enzyme immunoassay. Anti-Leptospira IgG antibodies were found in 17 (22.7%) of 75 patients and in 15 (10.0%) of 150 control subjects (OR = 2.32; 95% CI: 1.09-4.94; P=0.03). This is the first age- and gender-matched case control study about Leptospira seroprevalence in patients with liver diseases. Results indicate that Leptospira infection is associated with chronic and acute liver diseases. Results warrants for additional studies on the role of Leptospira exposure in chronic liver disease.

    We studed the hepatic echography patterns of young patients suffering from Wilson's Disease and compared these with results obtained from laboratory tests and parenchymal biopsy. Eight children, aged between 5 and 12 years (4 males and 4 females), were examined. The symptomatological pattern showed hepatomegaly and liver dysfunction with undetectable or very low serum ceruloplasmine levels and typical aspects of organic copper metabolism. In 50% of cases echography revealed a variable hyperreflection of the whole parenchyma, in connection with the presence of steatosis and aspects of intralobular inflammation. Fine and linear echoes were present, in 50% of the cases, with varying degrees of brightness, which was associated with the presence of fibrotic component or copper granules. Further echographic modifications were less frequent. Echography in close relatives of our patients was observed hepatomegaly and alteration of hepatic reflection associated with fibrotic component. In the evaluation of liver involvement in Wilson's Disease, these findings show that echotomography, when compared to hepatic biopsy, is less efficient in detecting different types of hepatic lesion but on a clinical basis it offers the possibility of evaluating their presence and gravity during the evolutive phase of the illness. This examination, unlike other methods, is completely non invasive; it may easily be repeated and may, in the future, come to be used as more precise diagnostic complement. 30 refs.

    Non-alcoholic fatty liver disease (NAFLD) is the most common liver disease in the developed world and its pathogenesis is complex and multifactorial. It is considered the hepatic manifestation of the metabolic syndrome and is the leading cause of hepatic cirrhosis. This review aims to present current knowledge on the involvement of the adrenal glands in the development of NAFLD. Clinical and animal studies have shown that excess glucocorticoids (GC) have been implicated in the pathogenesis of NAFLD. Patients with NAFLD seem to have a subtle chronic activation of the hypothalamic pituitary adrenal axis leading to a state of subclinical hypercortisolism. Regulators of GC such as 11β-hydroxysteroid dehydrogenase type 1 (11β-HSD1), an enzyme that regenerates cortisol from inactive cortisone, and 5α/5β-reductases, enzymes that increase cortisol clearance, are implicated in the development of NAFLD by amplifying local GC action. Adrenal androgen (dehydroepiandrosterone) abnormalities and increased aldosterone levels may also have a role in the development of NAFLD whereas the contribution of adrenergic signaling in NAFLD pathogenesis remains unclear.

    Full Text Available Still's disease (SD is a multisystemic inflammatory disease characterized by persistent arthritis and in many cases with fever of unknown origin. Diagnosis of SD is challenging because of nonspecific characteristics and especially in the case of a patient with solid organ transplantation and immunosuppressive therapy where multiple causes of fever are possible. There is no diagnostic test for SD, even though some useful diagnostic criteria or laboratory findings, such as serum ferritin levels, have been proposed, and useful imaging studies for the diagnosis or followup of SD have not been developed. We report the case of a 9-year-old child who presented with high grade fever associated with joint pain after a history of liver transplantation and immunosuppressive therapy. Laboratory tests showed increased acute phase reactants, elevated ferritin, and leukocytosis. An 18 F-fluorodeoxyglucose positron emission tomography (18F-FDG PET was performed identifying abnormal hypermetabolic areas localized in spleen, transplanted liver, and bone marrow secondary to inflammatory process. All infectious, autoimmune, and malignant causes were ruled out. A diagnosis of SD was performed and a steroid-based regimen was initiated with adequate response and no evidence of recurrence. To our knowledge this is the first case of SD following a solid organ transplant.

    Excessive consumption of alcoholic beverages is a serious cause of liver disease worldwide. The metabolism of ethanol generates reactive oxygen species, which play a significant role in the deterioration of alcoholic liver disease (ALD). Antioxidant phytochemicals, such as polyphenols, regulate the expression of ALD-associated proteins and peptides, namely, catalase, superoxide dismutase, glutathione, glutathione peroxidase, and glutathione reductase. These plant antioxidants have electrophilic activity and may induce antioxidant enzymes via the Kelch-like ECH-associated protein 1-NF-E2-related factor-2 pathway and antioxidant responsive elements. Furthermore, these antioxidants are reported to alleviate cell injury caused by oxidants or inflammatory cytokines. These phenomena are likely induced via the regulation of mitogen-activating protein kinase (MAPK) pathways by plant antioxidants, similar to preconditioning in ischemia-reperfusion models. Although the relationship between plant antioxidants and ALD has not been adequately investigated, plant antioxidants may be preventive for ALD because of their electrophilic and regulatory activities in the MAPK pathway.

    Full Text Available Summary: Hepatic steatosis is a highly prevalent liver disease, yet research is hampered by the lack of tractable cellular and animal models. Steatosis also occurs in cats, where it can cause severe hepatic failure. Previous studies demonstrate the potential of liver organoids for modeling genetic diseases. To examine the possibility of using organoids to model steatosis, we established a long-term feline liver organoid culture with adult liver stem cell characteristics and differentiation potential toward hepatocyte-like cells. Next, organoids from mouse, human, dog, and cat liver were provided with fatty acids. Lipid accumulation was observed in all organoids and interestingly, feline liver organoids accumulated more lipid droplets than human organoids. Finally, we demonstrate effects of interference with β-oxidation on lipid accumulation in feline liver organoids. In conclusion, feline liver organoids can be successfully cultured and display a predisposition for lipid accumulation, making them an interesting model in hepatic steatosis research. : In this study Kruitwagen and colleagues establish and characterize a feline liver organoid culture, which has adult stem cell properties and can be differentiated toward hepatocyte-like cells. They propose liver organoids as a tool to model hepatic steatosis and show that feline liver organoids accumulate more lipids than human organoids when provided with excess fatty acids.

    Our aim was to develop an accurate, non-invasive, blood-test-based method for identifying the main characteristics of liver fibrosis in non-alcoholic fatty liver disease (NAFLD). Fibrosis was staged according to NASH-CRN and Metavir systems in 226 patients with NAFLD. A fully automated algorithm measured the fractal dimension (FD) and the area of fibrosis (AOF). Independent predictors of diagnostic targets were determined using bootstrap methods. (i) Development. Significant fibrosis defined by NASH-CRN F ≥2 was diagnosed by weight, glycaemia, aspartate aminotransferase (AST), alanine aminotransferase (ALT) and prothrombin index [area under the receiver operating characteristic (AUROC)=0.867]; significant fibrosis defined by Metavir F ≥2 was diagnosed by weight, age, glycaemia, AST, ALT, ferritin and platelets (FibroMeter AUROC=0.941, Pfibrosis staging, Metavir staging was a better reference for blood test. Thus, the patient rate with predictive values ≥90% by tests was 97.3% with Metavir reference vs. 66.5% with NASH-CRN reference (Pfibrosis score for significant fibrosis, but not for severe fibrosis or cirrhosis, with both staging systems. Relationships between fibrosis lesions were well reflected by blood tests, e.g., the correlation between histological area and FD of fibrosis (r(s) =0.971, Pblood tests (r(s) =0.852, Pfibrosis in NAFLD can be diagnosed and quantified by blood tests with excellent accuracy. © 2010 John Wiley & Sons A/S.

    Malnutrition is found in almost 100% of patients with end stage liver disease (ESLD) awaiting transplantation and malnutrition before transplantation leads to higher rates of post-transplant complications and worse graft survival outcomes. Reasons for protein energy malnutrition include several metabolic alterations such as inadequate intake, malabsorption, and overloaded expenditure. And also, stress from surgery, gastrointestinal reperfusion injury, immunosuppressive therapy and corticosteriods use lead to delayed bowl function recovery and disorder of nutrients absorption. In the pretransplant phase, nutritional goals include optimization of nutritional status and treatment of nutrition-related symptoms induced by hepatic decompensation. During the acute post-transplant phase, adequate nutrition is required to help support metabolic demands, replenish lost stores, prevent infection, arrive at a new immunologic balance, and promote overall recovery. In a word, it is extremely important to identify and correct nutritional deficiencies in this population and provide an adequate nutritional support during all phases of liver transplantation (LT). This study review focuses on prevalence, nutrition support, evaluation, and management of perioperative nutrition disorder in patients with ESLD undergoing LT.

    Although alcoholic liver disease (ALD) is regarded as a common indication for liver transplantation (LT), debatable issues exist on the requirement for preceding alcoholic abstinence, appropriate indication criteria, predictive factors for alcoholic recidivism, and outcomes following living-donor LT. In most institutions, an abstinence period of six months before LT has been adopted as a mandatory selection criterion. Data indicating that pre-transplant abstinence is an associated predictive factor for alcoholic recidivism supports the reasoning behind this. However, conclusive evidence about the benefit of adopting an abstinence period is yet to be established. On the other hand, a limited number of reports available on living-donor LT experiences for ALD patients suggest that organ donations from relatives have no suppressive effect on alcoholic recidivism. Prevention of alcoholic recidivism has proved to be the most important treatment after LT based on the resultant inferior long-term outcome of patients. Further evaluations are still needed to establish strategies before and after LT for ALD.

    Cryosections of organs and smears from membrana nicitians from cats suspected of having spontaneous infection with feline infectious peritonitis virus (FIPV), were investigated using an indirect immunofluorescence assay (IIFA) in order to detect the presence of feline corona virus (FCV). In 113 cats, from each of which six organs were screened, virus antigen was found most often in membrana nicitians and lung. Out of these animals an additional six organs from a group of 30 cats were screened. In these cats membrana nicitians, parotid gland, thymus and apex of caecum had the highest incidence of virus antigen (90%). The lowest incidence of virus antigen was found in the spleen (60%). There was a clear demonstration of a higher incidence of antigen present in more than half of the total number of screened organs per cat (P less than 0.0005). No statistical difference was observed between sexes when comparing the incidence of virus antigen in different organs. Virus antigen was present in less organs in cats with no lesions suggestive of FIP disease compared to cats with such lesions (P less than 0.001). A similar distribution of the incidence of FCV antigen in the investigated organs was observed in these two groups.

    In the past 15 years mortality rates from liver disease have doubled in the UK. Brief alcohol advice is cost effective, but clinically meaningful reductions in alcohol consumption only occur in around 1 in 10 individuals. To provide evidence that detecting early liver disease in the community is feasible, practical, and that feedback of liver risk can increase the proportion of subjects reducing alcohol consumption. A community feasibility study in nine general practice sites in Hampshire. Hazardous and harmful drinkers were identified by WHO AUDIT questionnaire and offered screening for liver fibrosis. In total, 4630 individuals responded, of whom 1128 (24%) hazardous or harmful drinkers were offered a liver fibrosis check using the Southampton Traffic Light (STL) test; 393 (38%) attended and test results were returned by post. The STL has a low threshold for liver fibrosis with 45 (11%) red, 157 (40%) amber, and 191 (49%) green results. Follow-up AUDIT data was obtained for 303/393 (77%) and 76/153 (50%) subjects with evidence of liver damage reduced drinking by at least one AUDIT category (harmful to hazardous, or hazardous to low risk) compared with 52/150 (35%, PAUDIT >15), 22/34 (65%) of STL positives, reduced drinking compared with 10/29 (35%, PDetection of liver disease in the community is feasible, and feedback of liver risk may reduce harmful drinking.

    Full Text Available Introduction: It is long known that vitamin D deficiency was common in patients with liver disease, but little is known on the therapeutic effects of vitamin D, especially in patients with chronic liver disease. In this study, we aimed to systematically review the literatures and study the evidences in which the effects of vitamin D supplementation had been investigated on the severity of chronic liver disease or liver cirrhosis.Methods: A systematic literature search was performed by using the following key terms “vitamin D supplementation” and “chronic liver disease” in the PubMed, Scopus and Google scholar to find relevant articles. After collecting the eligible documents, data were extracted and described based on the purpose of this review.Result: Of total 196 articles found, only 7 relevant documents with 518 studied patients were included. The results of this study showed that the levels of 25(OH D were considerably lower in patients with chronic liver disease. Findings showed that vitamin D supplementation can rise up the mean serum level of 25(OH D in patients with severe vitamin D deficiency, especially patients with liver cirrhosis.Conclusion:The results of this review showed that vitamin D deficiency is associated with the severity of liver disease and may have prognostic value in the assessment of liver disease. Also, it was shown that vitamin D supplementation may be helpful for the treatment of liver disease at least in certain groups of patients.

    Coeliac disease (CD) is a gluten-sensitive enteropathy diagnosed on the basis of ESPGHAN criteria and clinical response to gluten-free diet (GFD). Histological abnormalities on liver biopsy have been noted in CD but have seldom been described. To assess the histological spectrum of 'coeliac hepatitis' and possibility of reversal of such features after a GFD. Twenty-five patients with concomitant CD and hepatic derangement were analysed for clinical profile, laboratory investigations and duodenal and liver biopsy. A histological comparison of pre- and post-GFD duodenal and liver biopsies was carried out, wherever possible. Fifteen patients presenting with CD subsequently developed abnormal liver function tests; 10 patients presenting with liver disease were found to have tissue positive transglutaminase in 70% and antigliadin antibodies in 60%. Serological markers for autoimmune liver disease (AILD) were positive in eight patients. Liver histology ranged from mild reactive hepatitis, chronic hepatitis, steatosis to cirrhosis. Liver biopsies after a GFD were available in six cases, of which five showed a decrease in steatosis, portal and lobular inflammation and fibrosis score. Coeliac hepatitis could be a distinct entity and the patients may present with either CD or secondary hepatic derangement. Evaluation for the presence of CD is recommended for patients presenting with AILD, unexplained transaminasaemia or anaemia. This is one of the very few studies demonstrating the continuum of liver histological changes in 'coeliac hepatitis'. Trial of a GFD may result in clinicopathological improvement of 'coeliac hepatitis'. © Article author(s) (or their employer(s) unless otherwise stated in the text of the article) 2018.

    Full Text Available Abstract Background Liver fibrosis is a stage of non-alcoholic fatty liver disease (NAFLD which is responsible for liver-related morbidity and mortality in adults. Accordingly, the search for non-invasive markers of liver fibrosis has been the subject of intensive efforts in adults with NAFLD. Here, we developed a simple algorithm for the prediction of liver fibrosis in children with NAFLD followed at a tertiary care center. Methods The study included 136 male and 67 female children with NAFLD aged 3.3 to 18.0 years; 141 (69% of them had fibrosis at liver biopsy. On the basis of biological plausibility, readily availability and evidence from adult studies, we evaluated the following potential predictors of liver fibrosis at bootstrapped stepwise logistic regression: gender, age, body mass index, waist circumference, alanine transaminase, aspartate transaminase, gamma-glutamyl-transferase, albumin, prothrombin time, glucose, insulin, triglycerides and cholesterol. A final model was developed using bootstrapped logistic regression with bias-correction. We used this model to develop the 'pediatric NAFLD fibrosis index' (PNFI, which varies between 0 and 10. Results The final model was based on age, waist circumference and triglycerides and had a area under the receiver operating characteristic curve of 0.85 (95% bootstrapped confidence interval (CI with bias correction 0.80 to 0.90 for the prediction of liver fibrosis. A PNFI ≥ 9 (positive likelihood ratio = 28.6, 95% CI 4.0 to 201.0; positive predictive value = 98.5, 95% CI 91.8 to 100.0 could be used to rule in liver fibrosis without performing liver biopsy. Conclusion PNFI may help clinicians to predict liver fibrosis in children with NAFLD, but external validation is needed before it can be employed for this purpose.

    Full Text Available Evidence suggests that nonalcoholic fatty liver disease (NAFLD and non-alcoholic steatohepatitis (NASH are associated with an increased risk of chronic kidney disease (CKD. In this study we aimed to evaluate whether the severity of liver fibrosis estimated by NAFLD fibrosis score is associated with higher prevalence of CKD in individuals with NAFLD. To this end NAFLD fibrosis score and estimated glomerular filtration rate (eGFR were assessed in 570 White individuals with ultrasonography-diagnosed NAFLD. As compared with subjects at low probability of liver fibrosis, individuals at high and intermediate probability showed an unfavorable cardio-metabolic risk profile having significantly higher values of waist circumference, insulin resistance, high sensitivity C-reactive protein, fibrinogen, uric acid and lower insulin-like growth factor-1 levels. Individuals at high and intermediate probability of liver fibrosis have lower eGFR after adjustment for gender, smoking, glucose tolerance status, homeostasis model assessment index of insulin resistance (HOMA-IR index, diagnosis of metabolic syndrome, statin therapy, anti-diabetes and anti-hypertensive treatments (P = 0.001. Individuals at high probability of liver fibrosis had a 5.1-fold increased risk of having CKD (OR 5.13, 95%CI 1.13-23.28; P = 0.03 as compared with individuals at low probability after adjustment for age, gender, and BMI. After adjustment for glucose tolerance status, statin therapy, and anti-hypertensive treatment in addition to gender, individuals at high probability of liver fibrosis had a 3.9-fold increased risk of CKD (OR 3.94, 95%CI 1.11-14.05; P = 0.03 as compared with individuals at low probability. In conclusion, advanced liver fibrosis, determined by noninvasive fibrosis markers, is associated with CKD independently from other known factors.

    Full Text Available Objective:Non-alcoholic fatty liver disease (NAFLD is affecting people worldwide with increasing prevalence. Non-invasive tests are required for both diagnosis and staging of the disease. We aimed to evaluate diagnostic accuracy of routine liver enzymes and cytokines in NAFLD. Methods:A total of 88 cases, aged between 20 and 62 years, were included in the study. Serum ALT, AST, GGT, triglyceride, TNF-alpha, IL-6 and IL-8 were measured in 40 patients with NAFLD and in 48 healthy control patients with similar BMI and demographic characteristics. Diagnostic performances of serum biomarkers for diagnosis of NAFLD were evaluated with ROC analysis. Results:ALT and AST showed good diagnostic performance in predicting patients with NAFLD in the overall group (AUC=0.817; 95% CI[0.721-0.913], AUC=0.815;95% CI[0.718-0.911] respectively but in obese subjects ALT and AST showed poor performance (AUC=0.659;95% CI[0.478-0.841], AUC=0.680; 95% CI[0.498-0.861] respectively. Among cytokines TNF-alpha showed best performance in the diagnosis of NAFLD in both overall group and obese subjects (AUC=0.892; 95% CI[0.824- 0.959], AUC=0.858; 95% CI[0.739-0.977] respectively. The optimal cut off value for TNF-alpha was 10.65pg/ml with a sensitivity of 75% and a specificity of 93% in the overall group. IL-6 and IL-8 showed poor performance. Conclusion: TNF-alpha may be a good parameter for predicting patients with NAFLD. J Clin Exp Invest 2015;6 (1: 16-20
