    Characteristic findings in patients with cirrhosis are vasodilatation with low overall systemic vascular resistance, high arterial compliance, increased cardiac output, secondary activation of counter-regulatory systems (renin-angiotensin-aldosterone system,sympathetic nervous system, release of vasopressin),and resistance to vasopressors. The vasodilatory state is mediated through adrenomedullin, calcitonin generelated peptide, nitric oxide, and other vasodilators,and is most pronounced in the splanchnic area.This constitutes an effective (although relative)counterbalance to increased arterial blood pressure.This review considers the alterations in systemic hemodynamics in patients with cirrhosis in relation to essential hypertension and arterial hypertension of the renal origin. Subjects with arterial hypertension (essential, secondary) may become normotensive during the development of cirrhosis, and arterial hypertension is rarely manifested in patients with cirrhosis, even in cases with renovascular disease and high circulating renin activity. There is much dispute as to the understanding of homoeostatic regulation in cirrhotic patients with manifest arterial hypertension. This most likely includes the combination of vasodilatation and vasoconstriction in parallel.

    Obesity is associated with increased cardiovascular disease (CVD) risk, especially when excess body fat is distributed preferentially within the abdominal region. Obese subjects usually have increased arterial stiffness compared with non-obese subjects of similar age. The factors associated with increased arterial stiffness in obesity include endothelial dysfunction (decreased nitric oxide bioavailability), impaired smooth muscle cell function, insulin resistance, as well as elevated cholesterol and C-peptide levels. Furthermore, visceral fat, the adipose tissue-related renin-angiotensin-aldosterone system and hyperleptinaemia contribute to the obesity-associated impaired arterial compliance. Weight loss improves CVD risk factors and arterial compliance. Because increased arterial stiffness is a marker of CVD risk these findings support the concept that the presence of obesity has vascular implications.

    Background Antihypertensive agents can reduce arterial stiffness. We hypothesized that an angiotensin receptor blocker (ARB) irbesartan and an angiotensin converting enzyme inhibitor (ACEI) lisinopril improved arterial compliance. Methods A randomized, double-blind, double-dummy, controlled crossover trial. Fifteen hypertensive patients, mean age 65.5 ± 8.9 years (mean ± SD) were given irbesartan (150 to 300 mg/day) or lisinopril (10 to 20 mg/day) for 12 weeks and then crossed over for 12 weeks. Pulse wave velocity (PWV) in the carotid-femoral (CF), carotid-radial (CR), and femoral dorsalis-pedis (FD) were measured using a Complior® PWV system. Results After 12 weeks, systolic blood pressure (SBP) decreased from 162.4 ± 12.9 to 134.5 ± 14.8 with irbesartan and to 145.2 ± 25 mmHg with lisinopril. Irbesartan and lisinopril reduced PWV (CF) in the elastic arterial system from 15.1 ± 5 to 13.3 ± 2.6 (p < 0.005) and to 14 ± 4.7 (p < 0.05) m/s respectively (p = 0.345). Irbesartan reduced PWV (CR) and PWV (FD), whereas lisinopril did not. The difference between treatments was significant after SBP adjustment (p = 0.037 for PWV (CR) and p < 0.001 for PWV (FD)). Conclusions Irbesartan improved arterial compliance in elastic and muscular arteries, whereas lisinopril improved it only in elastic arteries. PMID:19649309

  3. Mechanisms of decompensation and organ failure in cirrhosis: From peripheral arterial vasodilation to systemic inflammation hypothesis.

    2015-11-01

    The peripheral arterial vasodilation hypothesis has been most influential in the field of cirrhosis and its complications. It has given rise to hundreds of pathophysiological studies in experimental and human cirrhosis and is the theoretical basis of life-saving treatments. It is undisputed that splanchnic arterial vasodilation contributes to portal hypertension and is the basis for manifestations such as ascites and hepatorenal syndrome, but the body of research generated by the hypothesis has revealed gaps in the original pathophysiological interpretation of these complications. The expansion of our knowledge on the mechanisms regulating vascular tone, inflammation and the host-microbiota interaction require a broader approach to advanced cirrhosis encompassing the whole spectrum of its manifestations. Indeed, multiorgan dysfunction and failure likely result from a complex interplay where the systemic spread of bacterial products represents the primary event. The consequent activation of the host innate immune response triggers endothelial molecular mechanisms responsible for arterial vasodilation, and also jeopardizes organ integrity with a storm of pro-inflammatory cytokines and reactive oxygen and nitrogen species. Thus, the picture of advanced cirrhosis could be seen as the result of an inflammatory syndrome in contradiction with a simple hemodynamic disturbance.

    In the present work, we report a novel, in vivo, noninvasive technique to determine radial arterial compliance using the radial arterial pressure pulse waveform (RAPPW) acquired by fiber Bragg grating pulse recorder (FBGPR). The radial arterial compliance of the subject can be measured during sphygmomanometric examination by the unique signatures of arterial diametrical variations and the beat-to-beat pulse pressure acquired simultaneously from the RAPPW recorded using FBGPR. This proposed technique has been validated against the radial arterial diametrical measurements obtained from the color Doppler ultrasound. Two distinct trials have been illustrated in this work and the results from both techniques have been found to be in good agreement with each other.

    The aim of this study was to study the elasticity of the arterial wall using a non-invasive laser Doppler measurement system. The elasticity of the arterial wall is described by its compliance factor, which can be determined when both blood pressure and the radial velocity of the arterial wall are known. To measure radical velocity we used a self- mixing interferometer. The compliance factors were measured from six healthy volunteers, whose ages were varied from 21 to 32. Although a single volunteer's compliance factor is presented as an example, this paper treated the volunteers as a group. First, the elastic modulus, which is inversely proportional to the compliance factor, was determined. Then, an exponential curve was fitted into the measured data and a characteristic equation for the elastic modulus of the arterial wall was determined. The elastic modulus was calculated at different pressures and the results were compared to the static incremental modulus of a dog's femoral artery. The results indicate that there is a correlation between human elastic and canine static incremental modulus for blood pressures varying from 60 to 110 mmHg.

Methods In males, 72 cases were control group, 35 cases were EH-controlled,and 35 cases were EH-uncontrolled groups. Blood pressure and arterial compliance (C1 and C2) weredetected by HDI DO-2020. Results In the EH-uncontrolled group,the values of systolic blood pres-sure (SBP) , diastolic blood pressure (DBP) , mean arterial pressure (MAP), and pulse pressure(PP) were significantly higher than those of the control and the EH-controlled groups (P<0.01),however ,there was no difference between the control and the EH-controlled groups. In the EH-uncon-trolled group,the values of C1 and C2 were lower tlan those of both the control and the EH-controlledgroups (P<0.01) ,again,with no difference between the control and the EH-controlled groups. Con-clttsion Arterial compliance (C1 and C2) measurements may serve as a sensitive indicator of evalu-ating antihypertensive effect.

  10. Arterial blood pressure is closely related to ascites development in compensated HCV-related cirrhosis.

    Eduardo Vilar Gomez

    Full Text Available BACKGROUND: Arterial blood pressure (BP is a reliable marker of circulatory dysfunction in cirrhotic patients. There are no prospective studies evaluating the association between different levels of arterial BP and ascites development in compensated cirrhotic patients. Therefore, we evaluated the relationship between arterial BP and ascites development in compensated cirrhotic patients. MATERIALS AND METHODS: A total of 402 patients with compensated HCV-related cirrhosis were prospectively followed during 6 years to identify ascites development. At baseline, patients underwent systolic, diastolic and mean arterial pressure (MAP measurements. Any history of arterial hypertension was also recorded. The occurrence of events such as bleeding, hepatocellular carcinoma, death and liver transplantation prior to ascites development were considered as competing risk events. RESULTS: Over a median of 156 weeks, ascites occurred in 54 patients (13%. At baseline, MAP was significantly lower in patients with ascites development (75.9 mm/Hg [95%CI, 70.3-84.3] than those without ascites (93.6 mm/Hg [95% CI: 86.6-102.3]. After adjusting for covariates, the 6-year cumulative incidence of ascites was 40% (95%CI, 34%-48% for patients with MAP<83.32 mm/Hg. In contrast, cumulative incidences of ascites were almost similar among patients with MAP values between 83.32 mm/Hg and 93.32 mm/Hg (7% [95% CI: 4%-12%], between 93.32 mm/Hg and 100.31 mm/Hg (5% [95% CI: 4%-11%] or higher than 100.31 mm/Hg (3% [95% CI: 1%-6%]. The MAP was an independent predictor of ascites development. CONCLUSIONS: The MAP is closely related to the development of ascites in compensated HCV-related cirrhosis. The risk of ascites development increases in 4.4 fold for subjects with MAP values <83.32 mm/Hg.

    2014-05-01

    Full Text Available : INTRODUCTION: Hepatic encephalopathy is a reversible neuropsychiatry state that complicates liver disease. Pathogenesis of Hepatic Encephalopathy in chronic liver is function is widely accepted to be due to failure of hepatic clearance of toxins products from gut exact toxin involved remains controversial but ammonia is thought to be an important factor. Ammonia levels help both in diagnosis and serve as a guide in treatment. Diagnosis of Hepatic Encephalopathy can be done based on clinical criteria and the severity of Hepatic Encephalopathy can be graded by West Haven Criteria. This criterion is the simplest grading of Hepatic Encephalopathy based on clinical findings. AIMS AND OBJECTIVES: To correlate between Ammonia levels and clinical severity of Hepatic Encephalopathy in Cirrhosis of liver and correlate between Arterial versus venous ammonia levels with severity of Hepatic Encephalopathy. RESULTS: Male patients had higher incidence than females. Severity of hepatic encephalopathy was graded by West Haven grading. Arterial total ammonia and venous ammonia was correlated with the clinical severity of HE. Of the 50 patients 3 had grade 1, 18 had grade 2, 22 had grade 3 and 7 had grade 4. Arterial and venous ammonia levels co related with severity of HE. The highest level of arterial ammonia was seen in grade 3 and grade 4.It was seen that other lab parameters also increased with severity of HE. But were not significant. Serum albumin was inversely co related with severity of HE. CONCLUSIONS: Arterial total ammonia correlated better with the severity of Hepatic Encephalopathy as compared to venous ammonia levels. Venous total ammonia did not correlate with severity of Hepatic Encephalopathy and with arterial ammonia levels.

    AIM: Portopulmonary hypertension is a serious complication of chronic liver disease. Our aim was to search into the effect of terlipressin on systolic pulmonary artery pressure among cirrhotic patients.METHODS: Twelve patients (6 males and 6 females) with liver cirrhosis were recruited in the study. Arterial blood gas samples were obtained in sitting position at rest. Contrast enhanced echocardiography and measurements of systolic pulmonary artery pressure were performed before and after the intravenous injection of 2 mg terlipressin.RESULTS: Of 12 patients studied, the contrast enhanced echocardiography was positive in 5, and the positive findings in contrast enhanced echocardiography were reversed to normal in two after terlipressin injection. The mean systolic pulmonary artery pressure was 25.5±3.6 mmHg before terlipressin injection, and was 22.5±2.5 mmHg after terlipressin (P=0.003). The systolic pulmonary artery pressure was above 25 mmHg in seven of these 12 patients.After the terlipressin injection, systolic pulmonary artery pressure was <25 mmHg in four of these cases (58.3% vs 25%, P=0.04).CONCLUSION: Terlipressin can decrease the systolic pulmonary artery pressure in patients with liver cirrhosis.

    Background There is significant evidence showing that microalbuminuria and arterial compliance are sensitive markers for early cardiovascular diseases. However, whether microalbuminuria is associated with reduced arterial compliance in Chinese metabolic syndrome (MS) patients remains unknown.Methods According to the definition of MS proposed by ATPⅢ in 2001, USA, subjects (n=362) were divided into three groups according to the number of risk factors: group 1 (control), group 2 (medium, < 3 risk factors) and group 3 (MS, ≥ 3 risk factors). Both large artery compliance (C1) and small artery compliance (C2) were measured with the CVProfilor DO-2020 Cardiovascular Profiling System, and microalbuminuria was evaluated with the ratio of albumin to urine creatinine.Results (1) As C1 and C2 levels elasticity decreased, albumin creatinine ratio (ACR) and the prevalence of microalbuminuria increased within those groups with MS risk factors. C1 and C2 were negatively correlated with the ranking of MS risk factors, ACR was positively correlated with the ranking of MS risk factors (all P<0.05). (2) Subjects were also categorized into a microalbuminuria group and a normal group, C1 and C2 in the microalbuminuria group were lower than in the normal group. (3) Multivariate regression analysis showed that increased systolic blood pressure (SBP) and reduced arterial compliance were the main risk factors for microalbuminuria in the MS group.Conclusions The risk of developing microalbuminuria was higher in the subjects with multiple metabolic abnormalities.Increased systolic blood pressure and reduced arterial compliance may be the main predictors for microalbuminuria in MS.

    The purpose of this study was to determine the cumulative effects of repeated cycling sprints (Wingate tests) on carotid compliance and blood pressure (BP). Fourteen young, healthy men and women completed this study. Vascular and hemodynamic measurements were taken at rest, 5 min following a first Wingate test, 25 min following the first Wingate test, 5 min following a second Wingate test, and 25 min following the second Wingate test. At each time point, the measurements taken included brachial and carotid pulse pressure (PP), heart rate, carotid artery maximum and minimum diameters, and carotid compliance. Carotid BP was obtained with applanation tonometry. Carotid diameters were obtained using ultrasonography and compliance was calculated from carotid diameters and BP. Carotid and brachial PP increased significantly (P sprint, carotid arterial compliance decreased significantly more than 5 min following the first sprint (P sprint reduces carotid artery compliance immediately after exercise. Performance of a second identical cycling sprint further compounds this vascular change, reducing carotid artery compliance beyond levels seen following a single cycling sprint.

    Although branched chain amino acid (BCAA) supplementation improves malnutrition in cirrhotic patients, patient compliance with the administration of BCAA-rich supplements is poor due to their bitter taste. Since temperature is an important factor affecting taste, we examined the effect of heating on the stability of BCAAs and on the compliance of patients with liver cirrhosis with BCAA-rich supplement administration. A thermal denaturation test was first conducted, in which the BCAA-rich supplement Aminoleban® EN was heated to 37, 60, or 80°C for 30 or 60 min. The concentration of three amino acids, L-valine, L-leucine and L-isoleucine, was subsequently measured. The nutritional status of the cirrhotic patients was also evaluted. Patients presenting liver failure with a Child-Pugh class of A (n=2), B (n=2) or C (n=2) were hospitalized at Kurume University Hospital. Six patients with liver cirrhosis (HCV, n=3; HBV, n=1; alcohol, n=2) were enrolled. Venous blood samples were drawn in the morning after a 12-h overnight fast. The BCAA-rich supplement was administered to patients at room temperature (25°C) or heat loaded at 60°C for 10 min, with the temperature maintained above 45°C. Each patient was interviewed by a nationally registered dietitian regarding food consumption and intake of the BCAA-rich supplement immediately after each meal. Nutritional status was evaluated according to serum albumin levels, blood hemoglobin, prothrombin time and total lymphocyte count. No significant decrease was noted in valine, leucine or isoleucine levels following the heating of the BCAAs to 80°C. The caloric intake of the BCAA-rich supplement was significantly higher with administration after heating to 60°C, compared to caloric intake with administration at 25°C. In addition, heating of the BCAA-rich supplement significantly increased blood lymphocyte counts. In conclusion, heating did not affect the stability of the BCAAs, and may improve compliance with BCAA

    The mechanical properties of arteries are implicated in a wide variety of cardiovascular diseases, many of which are expected to involve a strong spatial variation in properties that can be depicted by diagnostic imaging. A pulse wave inverse problem (PWIP) is presented, which can produce spatially resolved estimates of vessel compliance from ultrasound measurements of the vessel wall displacements. The 1D equations governing pulse wave propagation in a flexible tube are parameterized by the spatially varying properties, discrete cosine transform components of the inlet pressure boundary conditions, viscous loss constant and a resistance outlet boundary condition. Gradient descent optimization is used to fit displacements from the model to the measured data by updating the model parameters. Inversion of simulated data showed that the PWIP can accurately recover the correct compliance distribution and inlet pressure under realistic conditions, even under high simulated measurement noise conditions. Silicone phantoms with known compliance contrast were imaged with a clinical ultrasound system. The PWIP produced spatially and quantitatively accurate maps of the phantom compliance compared to independent static property estimates, and the known locations of stiff inclusions (which were as small as 7 mm). The PWIP is necessary for these phantom experiments as the spatiotemporal resolution, measurement noise and compliance contrast does not allow accurate tracking of the pulse wave velocity using traditional approaches (e.g. 50% upstroke markers). Results from simulations indicate reflections generated from material interfaces may negatively affect wave velocity estimates, whereas these reflections are accounted for in the PWIP and do not cause problems.

    Background There are few studies on the arterial compliance of noise exposure. The purpose of this study was to understand the relationship between hearing loss, blood pressure and arterial compliance of female workers who exposed to occupational noise in a textile mill.Methods The noise levels in the workplace were measured with a HS6288 sound level meter. Cumulated noise exposure (CNE) was calculated according to the noise intensity and the exposure period. Hearing ability and arterial compliance were measured in 618 noise exposed workers. The database was set up with EpiData and the statistical analysis was performed with SAS software 9.1.3.Results The noise levels were 80.1dB(A) to 113.5dB(A), of which the levels at 92.5% of the noise monitoring sites were over the national standard. The incidence of high frequency hearing loss (HFHL) was 24.43% and language frequency hearing impairment (LFHI) was 0.81%. The incidence of hypertension was 7.93%. Both systolic blood pressure (SBP)and diastolic blood pressure (DBP) in the high frequency hearing loss group were significantly higher than those in the normal hearing group (P<0.05), while C1 (large artery compliance) and C2 (small artery compliance) were significantly lower (P<0.05). The high frequency hearing threshold (HFHT) of the hypertension group was significantly higher than in the normal blood pressure group (P<0.05), while C1 and C2 were significantly lower (P<0.05). C1 and C2 had a negative correlation with HFHT, SBP, DBP, mean of arterial pressure (MAP), pulse pressure (PP) and pulse rate (PR) (P<0.05).The multiple regression analyses showed that blood pressure and PR were the main influencing factors on C1 and C2.LFHT was an influence on C2 and HFHT on C1.Conclusions Textile mill noise pollution is very serious and has an obvious influence on worker's auditory function. The female workers with Iow artery compliance or with high blood pressure might be suffering from hearing loss; those with noise

    Objective To seek an association between total arterial compliance (TAC) and the extent of ischaemia at stress echocardiography. Design Cohort study. Setting Regional cardiac centre. Methods 255 consecutive patients (147 men; mean (SD) age 58 (8)) presenting for stress echocardiography for clinical indications were studied. Wall motion score index (WMSI) was calculated and ischaemia was defined by an inducible or worsening wall motion abnormality. Peak WMSI was used to reflect the extent of dysfunction (ischaemia or scar), and ΔWMSI was indicative of extent of ischaemia. TAC was assessed at rest by simultaneous radial applanation tonometry and pulsed wave Doppler in all patients. Results Ischaemia was identified by stress echocardiography in 65 patients (25%). TAC was similar in the groups with negative and positive echocardiograms (1.08 (0.41) v 1.17 (0.51) ml/mm Hg, not significant). However, the extent of dysfunction was associated with TAC independently of age, blood pressure, risk factors, and use of a β blocker. Moreover, the extent of ischaemia was determined by TAC, risk factors, and use of a β blocker. Conclusion While traditional cardiovascular risk factors are strong predictors of ischaemia on stress echocardiography, TAC is an independent predictor of the extent of ischaemia. PMID:16365349

    Purpose: To investigate the role of arterial-spin labeling (ASL) MRI to non-invasively characterize the patterns of cerebral blood flow (CBF) changes in cirrhotic patients and to assess the potential of ASL MRI to characterize minimal hepatic encephalopathy (MHE). Materials and methods: This study was approved by the local ethics committee, and written informed consent was obtained from all participants. Thirty six cirrhosis patients without overt hepatic encephalopathy (16 MHE patients and 20 non hepatic encephalopathy (non-HE) patients) and 25 controls underwent ASL MRI, and CBF was measured for each subject. One-way ANOCOVA test with age and gender as covariences was used to compare CBF difference among three groups, and post hoc analysis was performed between each two groups. Region-based correlation analysis was applied between Child–Pugh score, venous blood ammonia level, neuropsychological tests and CBF values in cirrhosis patients. Receiver operator characteristic (ROC) analysis was used for assessing CBF measurements in ASL MRI to differentiate MHE from non-HE patients. Results: The gray matter CBF of MHE patients (71.09 ± 11.88 mL min{sup −1} 100 g{sup −1}) was significantly higher than that of non-HE patients (55.28 ± 12.30 mL min{sup −1} 100 g{sup −1}, P < 0.01) and controls (52.09 ± 9.27 mL min{sup −1} 100 g{sup −1}, P < 0.001). Voxel-wise ANOCOVA results showed that CBFs were significantly different among three groups in multiple gray matter areas (P < 0.05, Bonferroni corrected). Post hoc comparisons showed that CBF of these brain regions was increased in MHE patients compared with controls and non-HE patients (P < 0.05, Bonferroni corrected). CBF of the right putamen was of the highest sensitivity (93.8%) and moderate specificity (75.0%) for characterization of MHE when using the cutoff value of 50.57 mL min{sup −1} 100 g{sup −1}.

    Key points A consistent inverse hyperbolic relationship has been observed between pulmonary vascular resistance and compliance, although changes in pulmonary artery wedge pressure (PAWP) may modify this relationship.This relationship predicts that pulmonary artery systolic, diastolic and mean pressure maintain a consistent relationship relative to the PAWP.We show that, in healthy exercising human adults, both pulmonary vascular resistance and compliance decrease in relation to exercise‐associated increases in PAWP.Pulmonary artery systolic, diastolic and mean pressures maintain a consistent relationship with one another, increasing linearly with increasing PAWP.Increases in PAWP in the setting of exercise are directly related to a decrease in pulmonary vascular compliance, despite small decreases in pulmonary vascular resistance, thereby increasing the pulsatile afterload to the right ventricle. Abstract The resistive and pulsatile components of right ventricular afterload (pulmonary vascular resistance, Rp; compliance, Cp) are related by an inverse hyperbolic function, expressed as their product known as RpCp‐time. The RpCp‐time exhibits a narrow range, although it may be altered by the pulmonary artery wedge pressure (PAWP). Identifying the determinants of RpCp‐time should improve our understanding of the physiological behaviour of pulmonary arterial systolic (PASP), diastolic (PADP) and mean (mPAP) pressures in response to perturbations. We examined the effect of exercise in 28 healthy non‐athletic adults (55 ± 6 years) who underwent right heart catheterization to assess haemodynamics and calculate Rp and Cp. Measurements were made at rest and during two consecutive 8–10 min stages of cycle ergometry, at targeted heart‐rates of 100 beats min–1 (Light) and 120 beats min–1 (Moderate). Cardiac output increased progressively during exercise. PASP, PADP, mPAP and PAWP increased for Light exercise, without any further rise for Moderate

    Relaxin is a potent vasodilator of small resistance arteries and modifies arterial compliance in some systemic vascular beds, yet receptors for relaxin, such as RXFP1, have only been localized to vascular smooth muscle. This study first aimed to localize RXFP1 in rat arteries and veins from different organ beds and determine whether receptors are present in endothelial cells. We then tested the hypothesis that region-specific vascular effects of relaxin may be influenced by the cellular localization of RXFP1 within different blood vessels. The aorta, vena cava, mesenteric artery, and vein had significantly higher (Pdifferential distribution of RXFP1 on endothelial and smooth muscle across the vasculature. In rats, mesenteric arteries exhibit the greatest functional response to chronic serelaxin treatment.

    The Central Artery/Tunnel (CA/T) Project in Boston, Massachusetts involves the replacement of the existing I-93 interstate highway (Central Artery) and the extension of I-90 (Massachusetts Turnpike) to Logan International Airport. To date, approximately 95 environmental and related permits have been obtained for the CA/T Project. At least 200 permits from federal, state and local regulatory agencies will be acquired for the entire Project. The proposed action includes construction activities and permanent structures related to the crossing of three bodies of water: Charles River, Fort Point Channel, and Boston Inner Harbor. The Project also includes work in Massachusetts filled tidelands, relocation or construction of outfalls, disposition of construction dewatering and tunnel drainage fluids, and capping of an abandoned landfill. The number of permits, interrelationships between permits and interfaces with design and construction schedules have necessitated the development and implementation of a permit tracking system. The system tracks permit applications from preparation through public and agency review to permit issuance. The issues are discussed in detail: Phased development of the tracking system; Utilization of Project standard scheduling system software, Primavera Project Planner; How the information generated by the tracking system is used at the Project; Report format and production; Construction phase services and the multidiscipline, integrated Project schedule.

    Branched-chain amino acids (BCAA) are used in attempts to reduce blood ammonia in patients with cirrhosis and intermittent hepatic encephalopathy based on the hypothesis that BCAA stimulate muscle ammonia detoxification. We studied the effects of an oral dose of BCAA on the skeletal muscle...... the metabolism of blood-supplied ammonia and the A-V measurements were used to measure the total ammonia metabolism across the thigh muscle. After intake of BCAA, blood ammonia increased more than 30% in both groups of subjects (both P ....05). BCAA intake led to a massive glutamine release from the muscle (cirrhotic patients, P BCAA enhanced the intrinsic muscle metabolism of ammonia but not the metabolism of blood-supplied ammonia in both the patients with cirrhosis and in the healthy...

  16. A STUDY OF HYPOXEMIA IN LIVER CIRRHOSIS

    Directory of Open Access Journals (Sweden)

    Gurinder

    2014-12-01

    Full Text Available INTRODUCTION: Pulmonary abnormalities and symptoms are common in patients with chronic liver disease. Hepatopulmonary syndrome is an important cause in a patient with hypoxemia and chronic liver disease. Hepatopulmonary syndrome consists of a triad of hepatic dysfunction and/or portal hypertension, intrapulmonary vascular dilatations and hypoxemia/ widened alveolar-arterial gradient. The present study evaluated the arterial blood gas levels and correlated these with 2D contrast echocardiographic findings in patients of liver cirrhosis. METHODS: 40 patients of liver cirrhosis were included in the study. All patients underwent ultrasonography, LFTs, biochemical tests and upper gastrointestinal endoscopy, chest X-ray, 2-D contrast enhanced transthoracic echocardiogram, viral markers and arterial blood gas analysis. The patients in whom arterial hypoxemia/ widened alveolar-arterial gradient was detected with a positive contrast echocardiogram were considered to have hepatopulmonary syndrome. Patients with intrinsic heart disease like patent foramen ovale, atrial septal defect, ventricular septal defect, haemoglobin less than 7gm% and history of COPD were excluded from the study. RESULTS: 4 patients of liver cirrhosis with hypoxemia had intrapulmonary vascular dilatations were labelled as hepatopulmonary syndrome. 2 additional patients with IPVDs had widened alveolar arterial gradient without hypoxemia and were also labelled as HPS. Dyspnoea (p=0.001, platypnea (p<0.001, clubbing (p=0.002 and cyanosis (p=0.001 were significantly commoner in the six patients of hepatopulmonary syndrome. Patients with cyanosis had poor prognosis. CONCLUSION: Hepatopulmonary syndrome is an important cause of hypoxemia in patients of liver cirrhosis. It is not uncommon in patients of liver cirrhosis. Platypnea is both sensitive as well as specific marker of the disease. Transthoracic contrast enhanced echocardiogram is a safe and accurate bedside tool for the detection

  20. Pathogenesis of water and sodium retention in cirrhosis.

    Science.gov (United States)

    Martin, P Y; Schrier, R W

    1997-06-01

    The pathogenesis of renal sodium and water retention in cirrhosis involves extrarenal mechanisms because when kidneys from cirrhotic patients are transplanted into persons with normal livers, renal sodium and water retention no longer occurs. Cirrhosis is accompanied by portal hypertension, which leads to a hyperdynamic circulatory state. The Peripheral Arterial Vasodilation Hypothesis incriminates a relative underfilling of the arterial vascular compartment, which leads to the same neurohumoral responses that occurs in low cardiac output. Activation of the renain-angiotensin-aldosterone axis and the sympathetic system as well as non-osmotic release of vasopressin are well documented in cirrhosis. This sequence of events results in renal water and sodium retention, failure to escape from the sodium-retaining effect of aldosterone, and renal resistance to atrial natriuretic peptide. Dilutional hyponatremia is the strongest predictor of the occurrence of hepatorenal syndrome. The pathogenesis of the peripheral arterial vasodilation is not completely elucidated, but there is evidence for a major role of nitric oxide (NO). Increased vascular NO production has been demonstrated in cirrhosis. In the rat model of cirrhosis, normalization of vascular NO production with a NOS inhibitor corrects the hyperdynamic circulation, improves sodium and water excretion, and decreases neurohumoral activation. This insight into the mechanism(s) of the peripheral arterial vasodilation in cirrhosis should provide new tools in the treatment of edema and ascites, a major cause of morbidity and mortality in cirrhosis.

    Hypertension is a risk factor for a long-lasting arterial wall-remodelling leading to stiffness. The rapid method measuring the pulse pressure (PP) by means of the tool of Hypertension Diagnostic Instruments (HDI) called PP-HDI, overcomes some of the problems arising with more-time consuming methods, like ambulatory blood pressure monitoring (ABPM), and give information about the elasticity of the arterial walls. We studied the relationship between the PP-HDI, the large artery compliance (LA-C) and small artery compliance (SA-C) and few well-established indices of arterial blood pressure (ABP) in a sample of 75 hypertensive subjects, aged 65 years and over. Significant correlations between LA-C and heart rate (HR), PP-ABPM and PP-HDI were found. SA-C relates with HR and systolic blood pressure (SBP) measured in lying and standing positions. Applying a stepwise regression analysis, we found that LA-C variance stems from PP-HDI and HR, while SA-C variance stems from SBP in lying position. Receiver operator characteristic (ROC) curves for thresholds of PP showed that PP-HDI reached levels of sensitivity/specificity similar to PP-ABPM. In conclusion, surveillance of ABP through hemo-dynamic indices, in particular of SBP, is essential, nevertheless the advantage of this control is not known in an elderly population where the organ damage is already evident. PP needs necessarily an instrumental measurement. The PP-HDI result is similar in reliability with respect to PPABPM, but is more rapid and well applicable in an elderly population.

    In this article, we present the CT and MR imaging characteristics of the cirrhotic liver. We describe the altered liver morphology in different forms of viral, alcoholic and autoimmune end-stage liver disease. We present the spectrum of imaging findings in portal hypertension, such as splenomegaly, ascites and varices. We describe the patchy and lacelike patterns of fibrosis, along with the focal confluent form. The process of hepatocarcinogenesis is detailed, from regenerative to dysplastic nodules to overt hepatocellular carcinoma. Different types of non-neoplastic focal liver lesions occurring in the cirrhotic liver are discussed, including arterially enhancing nodules, hemangiomas and peribiliary cysts. We show different conditions causing liver morphology changes that can mimic cirrhosis, such as congenital hepatic fibrosis, 'pseudo-cirrhosis' due to breast metastases treated with chemotherapy, Budd-Chiari syndrome, sarcoidosis and cavernous transformation of the portal vein.

    The diagnosis of cryptogenic cirrhosis (cirrhosis of unknown etiology) has dramatically decreased, following the discovery of hepatitis B virus (1965), hepatitis D virus (1977), hepatitis C virus (1989). Improving the diagnostic criteria for Autoimmune Hepatitis, by devising the scoring system and the recognition of the fact that Nonalcoholic Steatohepatitis can progress to cirrhosis (in 8 to 10 years), further reduced the diagnosis of cryptogenic cirrhosis.

Because a change in circulating leptin in cirrhosis could...... be caused by an altered production rate, altered disposal rate, or both, the present study was undertaken to identify regions of leptin overflow into the blood stream and regions of leptin extraction. Patients with alcoholic cirrhosis (n = 16) and control patients without liver disease (n = 12) were studied...... during catheterization with elective blood sampling from different vascular beds. Blood samples for leptin determination (radioimmunoassay) were taken simultaneously from artery/hepatic vein, artery/renal vein, artery/iliac vein, and artery/cubital vein.

    Doppler ultrasonography of the hepatic vasculature is an integral part of evaluating precirrhotic and cirrhotic patients. While the reversal of the portal venous flow is a well-recognized phenomenon, other flow patterns, although not as easily understood, may play an important role in assessing the disease status. This article discusses the different characteristic flow patterns observed from the portal vein, hepatic artery, and hepatic vein in patients with liver cirrhosis or related complications and procedures. Knowledge of these different flow patterns provides additional information that may reinforce the diagnosis of cirrhosis, help in staging, and offer prognostic information for determining the direction of therapy. Doppler ultrasonography is invaluable when liver transplantation is being considered and aids in the diagnosis of cirrhosis and portal hypertension.

    Full Text Available Accurate staging of hepatic cirrhosis is important in investigating the cause and slowing down the effects of cirrhosis. Computer-aided diagnosis (CAD can provide doctors with an alternative second opinion and assist them to make a specific treatment with accurate cirrhosis stage. MRI has many advantages, including high resolution for soft tissue, no radiation, and multiparameters imaging modalities. So in this paper, multisequences MRIs, including T1-weighted, T2-weighted, arterial, portal venous, and equilibrium phase, are applied. However, CAD does not meet the clinical needs of cirrhosis and few researchers are concerned with it at present. Cirrhosis is characterized by the presence of widespread fibrosis and regenerative nodules in the hepatic, leading to different texture patterns of different stages. So, extracting texture feature is the primary task. Compared with typical gray level cooccurrence matrix (GLCM features, texture classification from random features provides an effective way, and we adopt it and propose CCTCRF for triple classification (normal, early, and middle and advanced stage. CCTCRF does not need strong assumptions except the sparse character of image, contains sufficient texture information, includes concise and effective process, and makes case decision with high accuracy. Experimental results also illustrate the satisfying performance and they are also compared with typical NN with GLCM.

    Acute kidney injury (AKI) is a common and life-threatening complication in patients with cirrhosis. Recently, new criteria for the diagnosis of AKI have been proposed in patients with cirrhosis by the International Club of Ascites. Almost all types of bacterial infections can induce AKI in patients with cirrhosis representing its most common precipitating event. The bacterial infection-induced AKI usually meets the diagnostic criteria of hepatorenal syndrome (HRS). Well in keeping with the "splanchnic arterial vasodilation hypothesis", it has been stated that HRS develops as a consequence of a severe reduction of effective circulating volume related to splanchnic arterial vasodilation and to an inadequate cardiac output. Nevertheless, the role of bacterial infections in precipitating organ failures, including renal failure, is enhanced when their course is characterized by the development of a systemic inflammatory response syndrome (SIRS), thus, when sepsis occurs. Sepsis has been shown to be capable to induce "per se" AKI in animals as well as in patients conditioning also the features of renal damage. This observation suggests that when precipitated by sepsis, the pathogenesis and the clinical course of AKI also in patients with cirrhosis may differentiate to a certain extent from AKI with another or no precipitating factor. The purpose of this review is to describe the features of AKI precipitated by bacterial infections and to highlight whether infection and/or the development of SIRS may influence its clinical course, and, in particular, the response to treatment.

    Assessment of vascular compliance may be a useful measurement of the clinical effects of antihypertensive treatment. Both angiotensin-converting enzyme (ACE) inhibitors and calcium channel blockers are known to improve vascular elasticity. A study was performed to test the hypothesis that combined therapy with an ACE inhibitor and a calcium channel blocker would have additive benefits on vascular compliance at similar levels of blood pressure (BP), as compared with monotherapy with an ACE inhibitor. This 12-week, double-blind study was a substudy of a larger clinical hypertension study conducted in patients with hypertension and type 2 diabetes. Subjects (N = 20) were randomized to either a fixed-dose combination of amlodipine besylate/benazepril HCl or to enalapril monotherapy. BP, heart rate, large- and small-vessel compliance, systemic vascular resistance, and urinary microalbumin excretion were assessed at baseline and after treatment. Both treatments were similarly effective in lowering BP, reducing systemic vascular resistance, and decreasing urinary microalbumin excretion. Improvement in large-vessel compliance was significantly greater among subjects who received ACE-inhibitor/calcium channel blocker combination therapy (52%) as compared with those who received ACE-inhibitor monotherapy (32%; p < 0.05). No significant change in small-vessel compliance was observed with either treatment. Greater improvement in large-vessel compliance with combination therapy was independent of BP lowering.

    Despite the prolongation of coagulation tests, recent studies reported an increased frequency of thromboembolic events in patients with cirrhosis. The aim of this study was to evaluate the haemostatic balance in cirrhotic patients through assessing the variation of pro- and anticoagulant factors and evaluating the in-vitro thrombin generation in patients with cirrhosis and in healthy patients. Fifty-one cirrhotic patients with or without thromboembolic events and 50 controls matched by age and sex were enrolled. Procoagulant (factors VII, II, V, VIII, and XII) and inhibitor (protein C, protein S and antithrombin) factor activities were determined. Thrombin generation was measured as endogenous thrombin potential (ETP). Haemostatic balance was assessed by means of both procoagulant to inhibitor coagulation factor ratios and ETP with to without protein C activation ratios. There were 24 males and 27 females. The mean age was 57.8 years [16-91 years]. Pro and anticoagulant factors were significantly lower in patients than in controls (P < 0.001) except for factor VIII and protein S. In fact factor VIII level was significantly higher in patients than in controls and protein S levels were not significantly different between patients and controls. Almost all the pro to anticoagulant factor ratios were higher in cirrhotics than in controls, especially the factor VIII to protein C ratios which increased significantly from Child Pugh A to C (P < 0.001), the ratio of ETP with to without protein C activator was higher in patients than in controls, but did not reach a significant level (0.8 vs. 0.52) There was no statistically significant difference between Child classes. When comparing patients with history of thrombosis (n = 7) to those matched by age and sex and without history of thrombosis (n = 14), the ratios were not statistically different between the two groups. Haemostatic changes in cirrhosis tend to rebalance the haemostatic system. This state often

    2014-11-14

    Gut microbiota plays an important role in cirrhosis. The liver is constantly challenged with commensal bacteria and their products arriving through the portal vein in the so-called gut-liver axis. Bacterial translocation from the intestinal lumen through the intestinal wall and to mesenteric lymph nodes is facilitated by intestinal bacterial overgrowth, impairment in the permeability of the intestinal mucosal barrier, and deficiencies in local host immune defences. Deranged clearance of endogenous bacteria from portal and systemic circulation turns the gut into the major source of bacterial-related complications. Liver function may therefore be affected by alterations in the composition of the intestinal microbiota and a role for commensal flora has been evidenced in the pathogenesis of several complications arising in end-stage liver disease such as hepatic encephalopathy, splanchnic arterial vasodilatation and spontaneous bacterial peritonitis. The use of antibiotics is the main therapeutic pipeline in the management of these bacteria-related complications. However, other strategies aimed at preserving intestinal homeostasis through the use of pre-, pro- or symbiotic formulations are being studied in the last years. In this review, the role of intestinal microbiota in the development of the most frequent complications arising in cirrhosis and the different clinical and experimental studies conducted to prevent or improve these complications by modifying the gut microbiota composition are summarized.

    AIM: To evaluate hepatic reserve function by investigating the change of functional hepatic flow and total hepatic flow in cirrhotic patients with portal hypertension. METHODS: HPLC method was employed for the determination of concentration of D-sorbitol in human plasma and urine. The functional hepatic flow (FHF) and total hepatic flow (THF) were determined by means of modified hepatic clearance of D-sorbitol combined with duplex doppler color sonography in 20 patients with cirrhosis and 10 healthy volunteers. RESULTS: FHF, evaluated by means of bhe D-sorbitol dearance, was significantly reduced in patients wibh cirrhosis in comparison to controls (764.74±167.91 vs 1 195.04±242.97 mL/min, P<0.01). While THF was significantly increased in patients with cirrhosis in comparison to controls (1 605.23±279.99 vs 1 256.12±198.34 mL/min, P<0.01). Portal blood flow and hepatic artery flow all were increased in cirrhosis compared to controls (P<0.05 and P<0.01). D-sorbitol total clearance was significantly reduced in cirrhosis compared to control (P<0.01), while D-sorbitol renal clearance was significantly increased in cirrhosis (P<0.05). In controls FHF was similar to THF (1 195.05±242.97 vs1 256.12±198.34 mL/min, P=0.636), while FHF was significantly reduced compared with THF incirrhosis (764.74±167.91 vs 1 605.23±279.99 mL/min, P<0.01). CONCLUSION: Our method that combined modified hepatic clearance of D-sorbitol with duplex doppler color sonography is effective in the measurement of FHF and THF. FHF can be used to estimate hepatic reserve function.

    AIM: To investigate the inhibitory effect of natural taurine (Ntau) on portal hypertension (PHT) in rats with experimentally-induced liver cirrhosis (LC).METHODS: Experimentally-induced LC Wistar rats (20 rats/group) were treated with either oral saline or oral Ntau for 6 consecutive weeks. Evaluation parameters included portal venous pressure (PVP), portal venous resistance (PVR), portal venous flow (PVF), splanchnic vascular resistance (SVR) and mean arterial pressure (MAP). Vasoactive substance levels including nitric oxide (NO), nitric oxide synthase (NOS) and cyclic guanosine monophosphate (cGMP) were also measured.Histological investigation of type Ⅰ and Ⅲ collagen (COL Ⅰ and Ⅲ) and transforming growth factor-β1 (TGF-β1) was also performed. RESULTS: Treatment with Ntau (1) significantly decreased PVP, PVR and PVF, and increased MAP and SVP; (2) markedly increased the vascular compliance and reduced the zero-stress of the portal vein; (3) markedly decreased the amount of NO and cGMP and activity of NOS; and (4) improved the pathological status of the liver tissue and reduced the expression of COL Ⅰ, COL Ⅲ and TGF-β1. CONCLUSION: Ntau inhibited the LC-induced PHT by improving hyperdynamic circulation, morphology of liver and biomechanical properties of the portal vein in experimentally-induced LC rats.

    Full Text Available Abstract Primary biliary cirrhosis (PBC is a chronic and slowly progressive cholestatic liver disease of autoimmune etiology characterized by injury of the intrahepatic bile ducts that may eventually lead to liver failure. Affected individuals are usually in their fifth to seventh decades of life at time of diagnosis, and 90% are women. Annual incidence is estimated between 0.7 and 49 cases per million-population and prevalence between 6.7 and 940 cases per million-population (depending on age and sex. The majority of patients are asymptomatic at diagnosis, however, some patients present with symptoms of fatigue and/or pruritus. Patients may even present with ascites, hepatic encephalopathy and/or esophageal variceal hemorrhage. PBC is associated with other autoimmune diseases such as Sjogren's syndrome, scleroderma, Raynaud's phenomenon and CREST syndrome and is regarded as an organ specific autoimmune disease. Genetic susceptibility as a predisposing factor for PBC has been suggested. Environmental factors may have potential causative role (infection, chemicals, smoking. Diagnosis is based on a combination of clinical features, abnormal liver biochemical pattern in a cholestatic picture persisting for more than six months and presence of detectable antimitochondrial antibodies (AMA in serum. All AMA negative patients with cholestatic liver disease should be carefully evaluated with cholangiography and liver biopsy. Ursodeoxycholic acid (UDCA is the only currently known medication that can slow the disease progression. Patients, particularly those who start UDCA treatment at early-stage disease and who respond in terms of improvement of the liver biochemistry, have a good prognosis. Liver transplantation is usually an option for patients with liver failure and the outcome is 70% survival at 7 years. Recently, animal models have been discovered that may provide a new insight into the pathogenesis of this disease and facilitate appreciation for

    AIM: To evaluate ophthalmic disorders with special attention to retinopathy in cirrhotic patients. Vitamin A deficiency-related ophthalmopathy, xerophthalmia, and color blindness may be documented in cirrhosis due to various etiologies. Retinopathy is an obscure feature of cirrhosis. METHODS: Thirty-two cirrhotic patients, who were followed up by Clinics of Gastroenterology, Izmir Ataturk Teaching and Research Hospital, were enrolled to the study. Associated systemic diseases such as diabetes mellitus and hypertension were excluded. Thirty-two healthy volunteers took part as the control subjects. All participants had ophthalmologic examination in the same hospital. RESULTS: Five (15.6%) of the cirrhotic subjects had soft exudate in the retina. None of the control subjects had retinopathy (P<0.05). Intraocular pressure (IOP) measured for both eyes were also significantly lower in the cirrhotics (P<0.05 vs P = 0.01). There were no statistically significant differences between the two groups in terms of other ophthalmic pathologies. The ophthalmic findings did not show up any differences according to the etiology of cirrhosis. CONCLUSION: Soft exudates may develop in cirrhotic patients probably due to loss of synthetic function of liver and hemodynamic effects of portal hypertension. Retinopathy must be sought in cirrhosis because of its severe morbidity.

Cirrhosis is a major cause of morbidity and mortality in the USA, and according to the Centers for Disease Control and Prevention was responsible for 31,903 deaths in 2010 alone. It is thus of the utmost importance to appropriately manage these patients in the inpatient and outpatient setting to improve morbidity and mortality. In this review, we address four major areas of cirrhosis management: outpatient management of portal hypertension with decompensation, hepatic encephalopathy, hepatorenal syndrome, and bleeding/coagulation issues. Outpatient management covers recommendations for health care maintenance and screening. Hepatic encephalopathy encompasses a brief review of pathophysiology, treatment in the acute setting, and long-term prevention. Hepatorenal syndrome is discussed in regards to pathophysiology and treatment in the hospital setting. Finally, a discussion of the assessment of coagulation profiles in cirrhosis and recommendations for bleeding and thrombosis complications is included. These topics are not all encompassing with regard to this complicated population, but rather an overview of a few medical problems that are commonly encountered in their care.

    Ultrasound (US) is essential in both assessment of the potentially cirrhotic liver and surveillance of selected patients with chronic hepatitis as liver biopsy can be misleading or inaccurate in up to 25% of cases. Various techniques are already in routine use, such as grey-scale imaging, Doppler US, and contrast-enhanced US (CEUS), while newer techniques such as elastography and hepatic vein transit time (HVTT) have the potential to exclude patients without significant fibrosis or cirrhosis; however, they are operator dependent and require specific software. Grey-scale imaging may demonstrate changes, such as volume redistribution, capsule nodularity, parenchymal nodularity, and echotexture changes. The Doppler findings in the hepatic and portal veins, hepatic artery, and varices allow assessment of liver cirrhosis. However, the operator needs to be aware of limitations of these techniques. Low mechanical index CEUS plays an important role in the assessment of complications of cirrhosis, such as hepatocellular carcinoma and portal vein thrombus. Optimized US technique is crucial for accurate diagnosis of the cirrhotic liver and its complications.

    2010-01-01

    Primary biliary cirrhosis (PBC) is an autoimmune chronic liver disease characterized by progressive bile duct destruction eventually leading to cirrhosis, liver failure, and death. The autoimmune pathogenesis is supported by a plethora of experimental and clinical data, such as the presence of autoreactive T cells and serum autoantibodies. The etiology remains unknown, although evidence suggests a role for both genetic susceptibility and environmental factors that remain to be determined. In fact, a number of chemicals and infectious agents have been proposed to induce the disease in predisposed individuals. The recent availability of several murine models will significantly help in understanding pathphysiology mechanisms. In this review, we critically summarize the most recent data on the etiopathogenesis of PBC, discuss the latest theories and developments, and suggest directions for future research. PMID:20359968

    Interactions between the functioning of the heart andthe liver have been described, with heart diseasesaffecting the liver, liver diseases affecting the heart,and conditions that simultaneously affect both. Theheart is one of the most adversely affected organs inpatients with liver cirrhosis. For example, arrhythmiasand electrocardiographic changes are observed inpatients with liver cirrhosis. The risk for arrhythmia isinfluenced by factors such as cirrhotic cardiomyopathy,cardiac ion channel remodeling, electrolyte imbalances,impaired autonomic function, hepatorenal syndrome, metabolic abnormalities, advanced age, inflammatory syndrome, stressful events, impaired drug metabolism and comorbidities. Close monitoring of cirrhotic patients is needed for arrhythmias, particularly when QT intervalprolonging drugs are given, or if electrolyte imbalances or hepatorenal syndrome appear. Arrhythmia risk may persist after liver transplantation due to possible QT interval prolongation, persistence of the parasympathetic impairment, post-transplant reperfusion and chronic immunosuppression, as well as consideration of the fact that the transplant itself is a stressful event for the cardiovascular system. The aims of the present article were to provide a review of the most important data regarding the epidemiology, pathophysiology, and biomarkers of arrhythmia risk in patients with liver cirrhosis, to elucidate the association with long-term outcome, and to propose future research directions.

    Undeniably, handwashing remains the single most effective and cost-efficient method for preventing and reducing the transmission of nosocomial infections. Yet the rates and outbreaks of nosocomial infections in Canadian and international healthcare institutions continue to increase. Shaikh Khalifa Medical Center developed and implemented a multidisciplinary approach to address the challenges of handwashing compliance among nurses and healthcare workers in its workplace setting. Supported by evidence-based research, the approach consisted of three components: collaboration, implementation and evaluation. The use of the alcohol-based hand rub sanitizer or "solution" was integral to the multidisciplinary approach. Ongoing education, communication and a committed leadership were essential to promote and sustain handwashing compliance.

    The study objective was to compare the effect of different angles of lying positions on the physiological indices of patients with cirrhosis ascites. Chronic liver disease and cirrhosis were ranked 9th among the top 10 causes of death. Ascites is the most common cirrhosis comorbidity. Body posture can affect pulmonary ventilation and arterial oxygen partial pressure, making it an important clinical nursing intervention significantly affecting patient recovery. This was a quasi-experimental study design. From a medical center in Taiwan, 252 patients with cirrhosis ascites were recruited. Subjects were randomly divided into three groups by bed angle: 15°, 30°, and 45°. Physiological indices were measured at 5, 10, 15, 20, 25, and 30 minutes to determine any changes in heart rate, respiration rate, and oxygenation saturation. Data analysis included descriptive statistics and the generalized estimating equation for statistical analysis with significance set at α= 0.05. After controlling for confounding variables, the three groups differed significantly in heart rate at 20, 25, and 30 minutes, oxygenation saturations at 15 and 20 minutes, and respiration rate at 5 and 10 minutes (α< 0.05). Body posture can affect pulmonary ventilation and arterial oxygen partial pressure and is thus an important clinical nursing intervention that significantly affects the recovery of patients. When caring for patients with cirrhosis ascites, nurses should help patients to choose the most comfortable angle for them with no particular restrictions. Our results can be used to guide nurses in making a plan for health education and nursing that improves the quality of care for patients with chronic liver disease and cirrhosis patients with ascites.

    Familial Mediterranean fever (FMF) is a febrile disease characterized by acute, spontaneously resolving episodes of fever and pain caused by serosal inflammation and associated with mutations in the FMF gene, MEFV. Prophylaxis is maintained with colchicine. To our knowledge, no study has yet shown an association between FMF and cirrhosis of the liver. We conducted the current study to describe cryptogenic cirrhosis in FMF and to examine the possible relationship between the 2 entities. Patients with chronic liver disease were retrospectively identified through a computer search of a registry of 6000 patients with FMF followed in the clinics of the National Center for FMF. Data pertaining to FMF phenotype and genotype and characteristics of the liver disease were abstracted from patients' charts. Cryptogenic cause of cirrhosis was determined by exclusion of known causes of liver disease. Nine patients with cryptogenic cirrhosis were identified, comprising 0.15% of the FMF patient population, a rate significantly higher than the rate of 0.015% of cirrhosis of all types expected in the total population of Israel (p cirrhosis diagnosis, and was classified as A in 4 of them. These findings suggest that MEFV may serve as a modifier gene in cryptogenic cirrhosis. Genetic analysis in patients with cryptogenic cirrhosis unrelated to FMF, particularly patients of a Mediterranean origin, may be warranted in future studies.

    Intestinal microflora constitutes a symbiotic ecosystem in permanent equilibrium, composed mainly of anaerobic bacteria. However, such equilibrium may be altered by daily conditions as drug use or pathologies interfering with intestinal physiology, generating an unfavorable environment for the organism. Besides, there are factors which may cause alterations in the intestinal wall, creating the conditions for translocation or permeation of substances or bacteria. In cirrhotic patients, there are many conditions that combine to alter the amount and populations of intestinal bacteria, as well as the functional capacity of the intestinal wall to prevent the permeation of substances and bacteria. Nowadays, numerous complications associated with cirrhosis have been identified, where such mechanisms could play an important role. There is evidence that some probiotic microorganisms could restore the microbiologic and immunologic equilibrium in the intestinal wall in cirrhotic patients and help in the treatment of complications due to cirrhosis. This article has the objective to review the interactions between intestinal flora, gut permeability, and the actual role of probiotics in the field of cirrhotic patients.

    Full Text Available In this study, 44 patients with liver cirrhosis were investigated for hemostatic parameters. Patients with spontaneous bacterial peritonitis, hepatocellular carcinoma, hepatorenal syndrome and cholestatic liver diseases were excluded. Patients were classified by Child-Pugh criterion and according to this 4 patients were in Class A, 20 in Class B and 20 in C. Regarding to these results, it was aimed to investigate the haematological disturbances in liver cirrhotic patients.In the result there was a correlation between activated partial thromboplastin time, serum iron, ferritin, transferrin, haptoglobin and Child-Pugh classification. Besides there was no correlation between prothrombin time, factor 8 and 9, protein C and S, anti-thrombin 3, fibrinogen, fibrin degradation products, serum iron binding capacity, hemoglobin, leukocyte, mean corpuscular volume and Child-Pugh classification.There were significant difference, in terms of AST, ferritin, haptoglobulin, sex and presence of ascites between groups (p0.05. In the summary, we have found correlation between hemostatic abnormalities and disease activity and clinical prognosis in patients with liver cirrhosis which is important in the management of these patients. This is also important for identification of liver transplant candidiates earlier.

  14. The arterial load in pulmonary hypertension

    Directory of Open Access Journals (Sweden)

    A. Vonk-Noordegraaf

    2010-09-01

    Full Text Available The anatomical differences between the pulmonary and systemic arterial system are the main cause of the difference in distribution of compliance. In the pulmonary arterial system compliance is distributed over the entire arterial system, and stands at the basis of the constancy of the RC-time. This distribution depends on the number of peripheral vessels, which is ∼8–10 times more in the pulmonary system than the systemic tree. In the systemic arterial tree the compliance is mainly located in the aorta (80% of total compliance in thoracic-abdominal aorta. The constant RC-time in the pulmonary bed results in proportionality of systolic and diastolic pressure with mean pressure and, in turn, in the constant ratio of oscillatory and mean power.

    Purpose: The purpose of this study was to assess differences in enhancement effects of liver parenchyma between normal and cirrhotic livers on dynamic, Gd-EOB-DTPA enhanced MRI at 3 T. Materials and methods: 93 patients with normal (n = 54) and cirrhotic liver (n = 39; Child–Pugh class A, n = 18; B, n = 16; C, n = 5) underwent contrast-enhanced MRI with liver specific contrast media at 3 T. T1-weighted volume interpolated breath hold examination (VIBE) sequences with fat suppression were acquired before contrast injection, in the arterial phase (AP), in the late arterial phase (LAP), in the portal venous phase (PVP), and in the hepatobiliary phase (HBP) after 20 min. The relative enhancement (RE) of the signal intensity of the liver parenchyma was calculated for all phases. Results: Mean RE was significantly different among all evaluated groups in the hepatobiliary phase and with increasing severity of liver cirrhosis, a decreasing, but still significant reduction of RE could be shown. Phase depending changes of RE for each group were observed. In case of non-cirrhotic liver or Child–Pugh Score A cirrhosis mean RE showed a significant increase between AP, LAP, PVP and HBP. For Child–Pugh B + C cirrhosis RE increased until PVP, however, there was no change in case of B cirrhosis (p = 0.501) and significantly reduced in case of C cirrhosis (p = 0.043) during HBP. Conclusion: RE of liver parenchyma is negatively affected by increased severity of liver cirrhosis, therefore diagnostic value of HBP could be limited in case of Child Pugh B + C cirrhosis.

    Cirrhosis is the end result of nearly all forms of progressive liver disease. The diffuse hepatic process can be characterized as a state of inflammation progressing to fibrosis and resulting in nodular regeneration, ultimately leading to disorganized liver architecture and function. The underlying etiology of cirrhosis in children may often differ from adults owing to specific disease processes that manifest in childhood, including biliary atresia, galactosemia, and neonatal hepatitis. Although basic management strategies in children are similar to those in adults, the care given to children with cirrhosis must keep the child's growth and development of paramount importance.

    2016-01-01

    Full Text Available Sleep disturbances, particularly daytime sleepiness and insomnia, are common problems reported by patients suffering from liver cirrhosis. Poor sleep negatively impacts patients’ quality of life and cognitive functions and increases mortality. Although sleep disturbances can be an early sign of hepatic encephalopathy (HE, many patients without HE still complain of poor quality sleep. The pathophysiology of these disturbances is not fully understood but is believed to be linked to impaired hepatic melatonin metabolism. This paper provides an overview for the clinician of common comorbidities contributing to poor sleep in patients with liver disease, mainly restless leg syndrome and obstructive sleep apnea. It discusses nondrug and pharmacologic treatment options in these patients, such as the use of light therapy and histamine (H1 blockers.

    2011-01-01

    Full Text Available Primary biliary cirrhosis (PBC is a chronic immune-mediated cholestatic liver disease of unknown aetiology which affects mostly women in middle age. Familial PBC is when PBC affects more than one member of the same family, and data suggest that first-degree relatives of PBC patients have an increased risk of developing the disease. Most often, these familial clusters involve mother-daughter pairs, which is consistent with the female preponderance of the disease. These clusters provide evidence towards a genetic basis underlying PBC. However, clusters of nonrelated individuals have also been reported, giving strength to an environmental component. Twin studies have demonstrated a high concordance for PBC in monozygotic twins and a low concordance among dizygotic twins. In conclusion, studies of PBC in families clearly demonstrate that genetic, epigenetic, and environmental factors play a role in the development of the disease.

    Primary biliary cirrhosis (PBC) is an autoimmune disease of the liver characterized by progressive bile duct destruction eventually leading to cirrhosis and liver failure.The serological hallmark of the disease is the presence of circulating antimitochondrial antibodies (AMA).These reflect the presence of autoreactive T and B cells to the culprit antigens,the E2 subunits of mitochondrial 2-oxo-acid dehydrogenase enzymes,chiefly pyruvate dehydrogenase (PDC-E2).The disease results from a combination of genetic and environmental risk factors.Genetic predisposition is indicated by the higher familial incidence of the disease particularly among siblings and the high concordance rate among monozygotic twins.Environmental triggering events appear crucial to disrupt a preexisting unstable immune tolerance of genetic origin allowing,after a long latency,the emergence of clinical disease.Initiating mimetopes of the vulnerable epitope of the PDC-E2 autoantigen can be derived from microbes that utilize the PDC enzyme or,alternatively,environmental xenobiotics/chemical compounds that modify the structure of native proteins to make them immunogenic.A further alternative as a source of antigen is PDC-E2 derived from apoptotic cells.In the effector phase the biliary ductular cell,by reason of its proclivity to express the antigen PDC-E2 in the course of apoptosis,undergoes a multilineage immune attack comprised of CD4+ and CD8+ T cells and antibody.In this article,we critically review the available evidence on etiopathogenesis of PBC and present interpretations of complex data,new developments and theories,and nominate directions for future research.

    Background and Objectives Use of pluripotent stem cells is an ideal solution for liver insufficiencies. This work aims is to evaluate the safety and feasibility of autologous stem cells transplantation (SCT) in Egyptian patients of liver cirrhosis on top of hepatitis C virus (HCV). Subjects and Results 20 patients with HCV induced liver cirrhosis were divided into 2 groups. Group I: included 10 patients with liver cirrhosis Child score ≥9, for whom autologous stem cell transplantation was done using granulocyte colony stimulating factor (G-CSF) for stem cells mobilization. Separation and collection of the peripheral blood stem cells was done by leukapheresis. G-CSF mobilized peripheral blood mononuclear cells (G-CSF PB-MNCs) were counted by flow cytometry. Stem cell injection into the hepatic artery was done. Group II: included 10 patients with HCV induced liver cirrhosis as a control group. Follow up and comparison between both groups were done over a follow up period of 6 months. The procedure was well tolerated. Mobilization was successful and the total number of G-CSF PB-MNCs in the harvests ranged from 25×106 to 191×106. There was improvement in the quality of life, serum albumin, total bilirubin, liver enzymes and the Child-Pugh score of group I over the first two-three months after the procedure. Conclusion SCT in HCV induced liver cirrhosis is a safe procedure. It can improve the quality of life and hepatic functions transiently with no effect on the life expectancy or the fate of the liver cirrhosis. PMID:26634069

    Cardiovascular abnormalities accompany both portal hypertension and cirrhosis. These consist of hyperdynamic circulation, defined as reduced mean arterial pressure and systemic vascular resistance, and increased cardiac output. Despite the baseline increased cardiac output,ventricular inotropic and chronotropic responses to stimuli are blunted, a condition known as cirrhotic cardiomyopathy. Both conditions may play an initiating or aggravating pathogenic role in many of the complications of liver failure or portal hypertension including ascites,variceal bleeding, hepatorenal syndrome and increased postoperative mortality after major surgery or liver transplantation. This review briefly examines the major mechanisms that may underlie these cardiovascular abnormalities, concentrating on nitric oxide, endogenous cannabinoids, central neural activation and adrenergic receptor changes. Future work should address the complex interrelationships between these systems.

    The onset of hepatic decompensation in cirrhosisheralds an accelerated downhill course with pooroutcome. The sole predictor of this decompensation in cirrhosis is increased hepatic vein to portal veingradient hepatic venous pressure gradient (HVPG).Surrogate markers of liver function or hepatic reserveappear to be less relevant. The hepatic sinusoidsbecome less elastic and more rigid as liver fibrosisand cirrhosis progress. We propose that the Hagen-Poiseuille's law, which applies to rigid, but not elasticvessels, determines the pressure-flow characteristicsin the sinusoids. In the rigid cirrhotic liver, HVPG risesdramatically with any change in net surface areaor radius, r4 of the vasculature that follows surgicalresection. This review relates liver stiffness to therisk of decompensation in patients with cirrhosis. Theliver has a unique dual blood supply comprising a lowpressure portal vein and high pressure hepatic artery.We compare the complexity of autoregulation in thenormal elastic liver with that in the rigid cirrhotic liver.Therapeutic modalities to reduce portal pressure mayreduce the risk of hepatic decompensation and improveoutcomes in cirrhosis.

    Full Text Available Background. An adequate blood flow is directly related to graft survival in living donor liver transplantation. However, in some cases, unfavorable conditions prevent the use of the hepatic artery for arterial reconstruction. Herein, we report a case in which the recipient right gastroepiploic artery was used as an option for arterial reconstruction in adult-to-adult living donor liver transplantation. Case Report. A 62-year-old woman, with cirrhosis due to hepatitis B associated with hepatocellular carcinoma, was submitted to living donor liver transplantation. During surgery, thrombosis of the hepatic artery with intimal dissection until the celiac trunk was observed, which precluded its use in arterial reconstruction. We decided to use the right gastroepiploic artery for arterial revascularization of the liver graft. Despite the discrepancy in size between donor hepatic artery and recipient right gastroepiploic artery, anastomosis was performed successfully. Conclusions. The use of the right gastroepiploic artery as an alternative for arterial revascularization of the liver graft in living donor liver transplantation should always be considered when the hepatic artery of the recipient cannot be used. For performing this type of procedure, familiarity with microsurgical techniques by the surgical team is necessary.

    Full Text Available Mortality in cirrhosis is consequent of decompensation, only treatment being timely liver transplantation. Organ allocation is prioritized for the sickest patients based on Model for End Stage Liver Disease (MELD score. In order to improve survival in patients with high MELD score it is imperative to preserve them in suitable condition till transplantation. Here we examine means to prolong life in high MELD score patients till a suitable liver is available. We specially emphasize protection of airways by avoidance of sedatives, avoidance of Bilevel Positive Airway Pressure, elective intubation in grade III or higher encephalopathy, maintaining a low threshold for intubation with lesser grades of encephalopathy when undergoing upper endoscopy or colonoscopy as pre transplant evaluation or transferring patient to a transplant center. Consider post-pyloric tube feeding in encephalopathy to maintain muscle mass and minimize risk of aspiration. In non intubated and well controlled encephalopathy, frequent physical mobility by active and passive exercises are recommended. When renal replacement therapy is needed, night-time Continuous Veno-Venous Hemodialysis may be useful in keeping the daytime free for mobility. Sparing and judicious use of steroids needs to be borne in mind in treatment of ARDS and acute hepatitis from alcohol or autoimmune process.

    Among 18 patients diagnosed as posthepatitic cirrhosis of the liver at compen-sated stage, 12 were treated for 2 months with a vegetarian diet which provided a dailyintake of 2263 Kcal and 95g protein with 68g of it vegetable in origin, while the re-maining 6 patients were given a routine hospital diet and served as controls. After 2months of dietary treatment, there was a marked increase in the value of serum albuminand transferrin, an increase in 24 h urinary creatinine output and creatinine height indexwith a decrease in 24 h urinary output of urea nitrogen. The reverted A/G ratio was cor-rected and the negative nitrogen balance became positive. The protein synthetic rate turnedto become greater than the catabolic rate and the body protein flux decreased as mea-sured by the 15N-glycine tracer kinetic study. The paper concludes that a high caloric vege-tarian diet can influence favorably the whole body protein turnover in cirrhotic patientsand should thus be used at least as an adjuvant therapy in the management of these patients.

    The effect of orthotopic liver transplantation (OLT) on the systemic and splanchnic hemodynamic alterations of cirrhosis is still largely unknown. The aim of this study was to prospectively investigate the long-term changes induced by OLT on several hemodynamic parameters. In 28 patients undergoing OLT for cirrhosis, the following parameters were measured before surgery and subsequently at 6-month intervals (mean follow-up period, 17 months): cardiac index, mean arterial pressure (MAP), heart rate, total peripheral resistance (TPR), portal vein flow velocity and flow volume, spleen size, and Doppler ultrasound resistance or pulsatility indexes (RI or PI) in the: 1) interlobular renal, 2) superior mesenteric, 3) splenic, and 4) hepatic arteries. The same parameters were measured in 10 healthy controls. After OLT, cardiac index and heart rate significantly decreased (P Spleen size decreased significantly, but persisted to be larger than in controls. In conclusion, systemic, renal, and most, but interestingly not all, splanchnic circulatory alterations of cirrhosis are restored to normal after OLT.

    Background The hepatopulmonary syndrome (HPS) is a severe vascular complication in lungs resulting in systemic hypoxemia in patients with cirrhosis and portal hypertension. The underlying structural change in HPS is intrapulmonary vasodilation, which can lead to impaired oxygenation of pulmonary venous blood. It has been demonstrated that the heme oxygenase-1/carbon monoxide (HO-1/CO) system plays an important role in the control of vascular tone. The aim of this study was to further investigate the role of HO-1 in the pathogenesis of HPS in animal model.Methods Totally 35 rats were divided into liver cirrhosis, zinc protoporphyrin Ⅸ (ZnPP), cobalt protoporphyrin (CoPP)and sham groups. Biliary cirrhosis was established in the first three groups by bile duct ligation. Rats in the ZnPP and CoPP groups received once intraperitoneal injection of ZnPP and CoPP, respectively, 24 hours before sample collection.Expression of HO-1 mRNA in lung was detected by reverse-transcription polymerase chain reaction, while protein expression was determined by immunohistochemical analysis. Hematoxylin and eosin staining was performed to confirm the presence of liver cirrhosis and intrapulmonary vasodilation. Arterial blood gases, mean arterial pressure and portal vein pressure were also measured. Analysis of variance or Wilcoxon statistical methods were used to determine statistical significance.Results Compared with the sham group, the cirrhotic group demonstrated increased expression of pulmonary HO-1 mRNA and protein (P<0.01). The level of arterial carboxyhemoglobin (COHb), alveolar-arterial oxygen gradient (A-aPO2),mean arterial pressure, portal vein pressure (P<0.05, respectively), and intrapulmonary vasodilation were also significantly increased. Compared with the cirrhotic group, CoPP treatment increased pulmonary HO-1 mRNA and protein expression, the level of A-aPO2 (P <0.05 respectively), COHb (P <0.01), and intrapulmonary vasodilation, while ZnPP treatment

    Abstract To provide an overview of the medical literature on giant splenic artery aneurysm (SAA). The PubMed, Medline, Google Scholar, and Google databases were searched using keywords to identify articles related to SAA. Keywords used were splenic artery aneurysm, giant splenic artery aneuryms, huge splenic artery aneurysm, splenic artery aneurysm rupture, and visceral artery aneurysm. SAAs with a diameter ≥5 cm are considered as giant and included in this study. The language of the publication was not a limitation criterion, and publications dated before January 15, 2015 were considered. The literature review included 69 papers (62 fulltext, 6 abstract, 1 nonavailable) on giant SAA. A sum of 78 patients (50 males, 28 females) involved in the study with an age range of 27–87 years (mean ± SD: 55.8 ± 14.0 years). Age range for male was 30–87 (mean ± SD: 57.5 ± 12.0 years) and for female was 27–84 (mean ± SD: 52.7 ± 16.6 years). Most frequent predisposing factors were acute or chronic pancreatitis, atherosclerosis, hypertension, and cirrhosis. Aneurysm dimensions were obtained for 77 patients with a range of 50–300 mm (mean ± SD: 97.1 ± 46.0 mm). Aneurysm dimension range for females was 50–210 mm (mean ± SD: 97.5 ± 40.2 mm) and for males was 50–300 mm (mean ± SD: 96.9 ± 48.9 mm). Intraperitoneal/retroperitoneal rupture was present in 15, among which with a lesion dimension range of 50–180 mm (mean ± SD; 100 ± 49.3 mm) which was range of 50–300 mm (mean ± SD: 96.3 ± 45.2 mm) in cases without rupture. Mortality for rupture patients was 33.3%. Other frequent complications were gastrosplenic fistula (n = 3), colosplenic fistula (n = 1), pancreatic fistula (n = 1), splenic arteriovenous fistula (n = 3), and portosplenic fistula (n = 1). Eight of the patients died in early postoperative period while 67 survived. Survival status of the

    Hepatopulmonary syndrome is characterized by a triad consisting of liver disorder, pulmonary vascular dilatation, and hypoxaemia. No case of hepatopulmonary syndrome associated with AIDS has been reported so far. In this study, the authors report the case of a 43-year woman with AIDS and virus C cirrhosis taking prophylactic cotrimoxazole for pneumocystosis and retroviral therapy. Upon admission, the patient presented dyspnoea, cyanosis, digital clubbing, vascular spiders, and normal chest examination. Chest X-ray revealed bilateral interstitial infiltration and evidenced increased alveolar-arterial gradient and liver function impairment. Intrapulmonary shunt was evidenced by contrast-enhanced echocardiography and radionuclide perfusion scanning, thus confirming hepatopulmonary syndrome. (author)

  20. Inflammasome activation in decompensated liver cirrhosis

    Institute of Scientific and Technical Information of China (English)

    2016-01-01

    Inflammation participates in the pathogenesis of many liver diseases, including liver cirrhosis. Certaininflammatory citokines, such as interleukin (IL)-1β andIL-18, are produced after the activation of a multiproteincomplex known as the inflammasome. Activation of theinflammasome has been documented in several liverdiseases, but its role in the development and progressionof liver cirrhosis or the complications associated withthis disease is still largely unknown. We have recentlystudied the impact of the inflammasome in the sterileinflammatory response that takes place in the asciticfluid of patients with decompensated cirrhosis, providingevidence that activation of the absent in melanoma2 (AIM2) inflammasome is an important response inthese patients. Ascitic fluid-derived macrophages wereable to mount a very robust AIM2-mediated responseeven in the absence of a priming signal, which is usuallyrequired for the full activation of all the inflammasomes.In addition, high level of inflammasome activation inthese patients was associated with a higher degree ofliver disease and an increased incidence of spontaneousbacterial peritonitis. These results may help explain theexacerbated inflammatory response that usually occursin patients with decompensated cirrhosis in the absenceof detectable infections. Thus, inflammasomes shouldbe considered as possible therapeutic targets in sterileinflammatory complications in patients with cirrhosis.

    Nonalcoholic steatohepatitis (NASH) associated cirrhosis is an increasing indication for liver transplant (LT). The aim of this study was to determine outcome and poor predictive factors after LT for NASH cirrhosis. We analyzed patients undergoing LT from 1997 to 2008 at a single center. NASH was diagnosed on histopathology. LT recipients with hepatitis C, alcoholic or cholestatic liver disease and cryptogenic cirrhosis acted as matched controls. Ninety-eight LT recipients were identified with NASH cirrhosis. Compared to controls, NASH patients had a higher BMI (mean 32.3 kg/m2), and were more likely to be diabetic and hypertensive. Mortality after transplant was similar between NASH patients and controls but there was a tendency for higher earlier mortality in NASH patients (30-day mortality 6.1%, 1-year mortality 21.4%). Sepsis accounted for half of all deaths in NASH patients, significantly higher than controls. NASH patients > or =60 years, BMI > or =30 kg/m2 with diabetes and hypertension (HTN) had a 50% 1-year mortality. In conclusion, patients undergoing LT for NASH cirrhosis have a similar outcome to patients undergoing LT for other indications. The combination of older age, higher BMI, diabetes and HTN are associated with poor outcome after LT. Careful consideration is warranted before offering LT to these high-risk patients.

    Several conditions, especially chronic liver diseases,can lead to cirrhosis in children and adolescents. Mostcases in clinical practice are caused by similar etiologies.In infants, cirrhosis is most often caused by biliaryatresia and genetic-metabolic diseases, while in olderchildren, it tends to result from autoimmune hepatitis,Wilson's disease, alpha-1-antitrypsin deficiency andprimary sclerosingcholangitis. The symptoms of cirrhosisin children and adolescents are similar to those ofadults. However, in pediatric patients, the first sign ofcirrhosis is often poor weight gain. The complications ofpediatric cirrhosis are similar to those observed in adultpatients, and include gastrointestinal bleeding causedby gastroesophageal varices, ascites and spontaneousbacterial peritonitis. In pediatric patients, specialattention should be paid to the nutritional alterationscaused by cirrhosis, since children and adolescentshave higher nutritional requirements for growth anddevelopment. Children and adolescents with chroniccholestasis are at risk for several nutritional deficiencies.Malnutrition can have severe consequences for bothpre- and post-liver transplant patients. The treatmentof cirrhosis-induced portal hypertension in children andadolescents is mostly based on methods developed foradults. The present article will review the diagnostic anddifferential diagnostic aspects of end-stage liver diseasein children, as well as the major treatment options forthis condition.

    We describe a 36 year old man who was admitted to the hospital with dyspnea, edema of the lower limbs, arterial hypertension and oliguric renal failure. He had microhematuria and nephrotic range proteinuria, immunological tests were normal or negative. Renal biopsy revealed global (55%) or segmental glomeruloesclerosis, remaining glomeruli showed extracapillary proliferation (25%). Immunofluorescence study disclosed IgA mesangial deposits. He was also diagnosed as having liver cirrhosis with positive serology against hepatitis C virus. He was treated with dialysis, antihypertensive drugs and steroids with improvement of the renal function. However, ten months later maintenance hemodialysis became necessary. We emphasize two points: first IgA glomerulonephritis is rarely associated with hepatitis C infection, and second crescentic IgA nephropathy has been infrequently reported in liver cirrhosis.

  5. Update on Primary Biliary Cirrhosis

    2000-01-01

    Full Text Available The diagnosis of primary biliary cirrhosis (PBC is most often made in the asymptomatic phase, sometimes before the development of abnormal liver biochemistry. The antimitochondrial antibody remains the predominant hallmark, although not all patients test positive, even when the most sensitive techniques are used. The etiology of PBC remains elusive; studies suggest that the interlobular bile duct destruction is immune based, and associated autoimmune diseases are common. There are no surrogate markers that predict outcome in asymptomatic patients, whose chance of survival is less than that of age- and sex-matched populations but much better than the median survival of eight years in patients with symptomatic PBC. Symptoms common in this disease are fatigue, pruritus and xanthelasma, as well as complications of portal hypertension and osteoporosis. Treatment includes symptomatic and preventive measures, as well as specific therapeutic measures. Immunosuppressive therapy has yielded disappointing results in the long term management of PBC, and the only therapy shown to improve survival is the hydrophobic dihydroxy bile acid ursodeoxycholic acid. Treatment at a dose of 13 to 15 mg/kg/day is optimal, given in separate doses or as a single dose at least 4 h from giving the oral anion exchange resin cholestyramine, which may be used to control pruritus. However, liver transplantation remains the only cure for this disease, and the best postoperative survival is seen in patients whose serum bilirubin does not exceed 180 µmol/L at the time of liver transplantation. Recurrence takes place but is rarely symptomatic and does not deter from the benefits of transplantation.

  6. Liver Cirrhosis and Intestinal Bacterial Translocation

    Institute of Scientific and Technical Information of China (English)

    2014-01-01

    Intestinal barrier dysfunction, facilitating translocation of bacteria and bacterial products, plays an important role in the pathophysiology of liver cirrhosis and its complications. Intestinal defense system including microbial barrier, immunologic barrier, mechanical barrier, chemical barrier, plays an important role in the maintenance of intestinal function. Under normal circumstances, the intestinal barrier can prevent intestinal bacteria through the intestinal wall from spreading to the body. Severe infection, trauma, shock, cirrhosis, malnutrition, immune suppression conditions, intestinal bacteria and endotoxin translocation, can lead to multiple organ dysfunction. The intestinal microlfora is not only involved in the digestion of nutrients, but also in local immunity, forming a barrier against pathogenic microorganisms. The derangement of the gut microlfora may lead to microbial translocation, deifned as the passage of viable microorganisms or bacterial products from the intestinal lumen to the mesenteric lymph nodes and other extraintestinal sites. In patients with cirrhosis, primary and intestinal lfora imbalance, intestinal bacterial overgrowth, intestinal mucosal barrier dysfunction, endotoxemia is associated with weakened immunity.

  8. Cryptogenic cirrhosis: what are we missing?

    Science.gov (United States)

    Caldwell, Stephen

    2010-02-01

    Cryptogenic cirrhosis remains a common clinical condition although recent advances have allowed for a better understanding of underlying conditions and associations. The evolving terminology applied to this condition has resulted in some confusion and persistent variation among pathologists and clinicians. Typical patients are middle aged with only minor liver enzyme abnormalities. Presentations range from incidentally discovered cirrhosis to complications of advanced portal hypertension and hepatocellular cancer. Clinicopathologic analysis of these patients indicates that the leading causes include previously unrecognized nonalcoholic steatohepatitis, silent autoimmune hepatitis, non-B, non-C viral hepatitis, and occult past ethanol exposure. In this article, we review these associations as well as a proposed classification system for cryptogenic cirrhosis and other lesser known genetic and syndromic associations that warrant consideration when evaluating these individuals.

    AIM: Many cirrhotic patients have muscular symptoms and rhabdomyolysis. However, myopathy associated with liver cirrhosis has not been established as a disease entity. We evaluated the clinical significance of acute myopathy associated with liver cirrhosis.METHODS: We retrospectively reviewed the medical records of 5440 cirrhotic patients who had been admitted to Gyeongsang National University Hospital from August 1997 to January 2003. Among these, 99 developed acute myopathies, and they were analyzed with respect to clinical and laboratory parameters, and outcomes.RESULTS: The Child-Pugh classification at the time of myopathy onset was A in 3(3.1%) cases, B in 33(33.3%), and C in 63 (63.6%). Infection was identified as the most predisposing factor to myopathy. Fifty percent of 18 idiopathic cases who were tested for influenza antibody were positive. Forty-two of the 99 cases were complicated by acute renal failure, and 25 (59.5%) of these expired. Apart from 6 cases lost to follow-up, 64 of 93 recovered, giving a mortality rate of 31.2%. Mortality was higher in Child-Pugh class C than in B or A.CONCLUSION: Acute myopathy can develop as a serious complication in liver cirrhosis. Its frequency, severity and mortality depend on underlying liver function, and are higher in decompensated liver cirrhosis. Influenza should be considered as an etiologic factor in idiopathic cases. It is proposed that acute myopathy associated with liver cirrhosis be called 'hepatic myopathy', and that careful monitoring for hepatic myopathy is necessary in the patients with advanced liver cirrhosis.

    2015-01-01

    Acute renal failure, now termed acute kidney injury(AKI), is frequently found in patients with cirrhosis. The occurrence of AKI, irrespective of the underlying cause, is associated with reduced in-hospital, 3-mo and 1-year survival. Hepatorenal syndrome is associated with the worst outcome among AKI patients with cirrhosis. Several definitions for AKI that have been proposed are outlined and evaluated in this paper. Among these, the International Club for Ascites-AKI criteria substantially strengthen the quality of early diagnosis and intervention according to underlying cause of AKI.

    Full Text Available Nature of violations of hemostasis system in cirrhosis is difficult, often unpredictable and concerns all its links. Thus both bleedings and thrombosis are possible. Disease decompensation is accompanied by deeper haemostatic imbalance towards thrombophilia. It is connected with that hepatocytes is the main place of synthesis vitamin K dependent pro- and anticoagulant proteins. Respectively, medical tactics should be directed on correction of pathogenetic mechanisms of haemostatic imbalance. Aim. To estimate influence Vikasolum on pro- and anticoagulant link of hemostasis in patients with cirrhosis. Methods and results. 30 patients with cirrhosis were under supervision. Patients received Vikasolum in dose 1.0 ml of 0.01 % solution intramuscularly 3 times a day within 3-4 days, with shift to oral route – on 1 tablet (0.015 twice a day up to 2 weeks. Estimation of procoagulant unit included determination of the number of platelets, prothrombin index, activated partial thromboplastin time, blood-coagulation factor F VIII, fibrinogen levels, «B» and D-dimer fibrinogen. Anticoagulant system was evaluated with activity of coagulation inhibitor of protein C. It is shown that hemostasis condition is characterised by an imbalance towards hyper coagulation on the ground of normal or hyperactivated blood-coagulation factor F VIII in patients with cirrhosis. At appointment of vikasoli increase levels of a protrombin index and the protein C is noted. Conclusion. Vikasolum intake promotes normalisation of a haemostatic imbalance, vitamin K dependent pro- and antikoagulyant factors synthesis.

  14. Cirrhosis and autoimmune liver disease: Current understanding

    Science.gov (United States)

    Liberal, Rodrigo; Grant, Charlotte R

    2016-01-01

    Primary biliary cirrhosis (PBC), primary sclerosing cholangitis (PSC) and autoimmune hepatitis (AIH) constitute the classic autoimmune liver diseases (AILDs). While AIH target the hepatocytes, in PBC and PSC the targets of the autoimmune attack are the biliary epithelial cells. Persistent liver injury, associated with chronic AILD, leads to un-resolving inflammation, cell proliferation and the deposition of extracellular matrix proteins by hepatic stellate cells and portal myofibroblasts. Liver cirrhosis, and the resultant loss of normal liver function, inevitably ensues. Patients with cirrhosis have higher risks or morbidity and mortality, and that in the decompensated phase, complications of portal hypertension and/or liver dysfunction lead to rapid deterioration. Accurate diagnosis and monitoring of cirrhosis is, therefore of upmost importance. Liver biopsy is currently the gold standard technique, but highly promising non-invasive methodology is under development. Liver transplantation (LT) is an effective therapeutic option for the management of end-stage liver disease secondary to AIH, PBC and PSC. LT is indicated for AILD patients who have progressed to end-stage chronic liver disease or developed intractable symptoms or hepatic malignancy; in addition, LT may also be indicated for patients presenting with acute liver disease due to AIH who do not respond to steroids.

    AIM: To evaluate safety and feasibility of autologous bone marrow-enriched CD34+ hematopoietic stem cell Tx through the hepatic artery in patients with decompensated cirrhosis.METHODS: Four patients with decompensated cirrhosis were included. Approximately 200 mL of the bone marrow of the patients was aspirated, and CD34+ stem cells were selected. Between 3 to 10 million CD34+ cells were isolated. The cells were slowly infused through the hepatic artery of the patients.RESULTS: Patient 1 showed marginal improvement in serum albumin and no significant changes in other test results. In patient 2 prothrombin time was decreased;however, her total bilirubin, serum creatinine, and Model of End-Stage Liver Disease (MELD) score worsened at the end of follow up. In patient 3 there was improvement in serum albumin, porthrombin time (PT), and MELD score. Patient 4 developed radiocontrast nephropathy after the procedure, and progressed to type 1 hepatorenal syndrome and died of liver failure a few days later. Because of the major side effects seen in the last patient, the trial was prematurely stopped.CONCLUSION: Infusion of CD34+ stem cells through the hepatic artery is not safe in decompensated cirrhosis.Radiocontrast nephropathy and hepatorenal syndrome could be major side effects. However, this study does not preclude infusion of CD34+ stem cells through other routes.

    Full Text Available Abstract Background Antioxidant supplementations have the potential to alleviate the atherosclerotic damage caused by excessive production of reactive oxygen species (ROS. The present study evaluated the effects of prolonged antioxidant treatment on arterial elasticity, inflammatory and metabolic measures in patients with multiple cardiovascular risk factors. Methods Study participants were randomly assigned to two groups. Group 1 received oral supplementation with 2 capsules per day of Mid Life Guard, SupHerb, Israel. In each capsule vitamin C (500 mg vitamin E (200 iu, co-enzyme Q10 (60 mg and selenium (100 mcg, Group 2 received matching placebo(SupHerb for 6 months. Patients were evaluated for lipid profile, HbA1C, insulin, C-peptide, hs-CRP, endothelin, aldosterone, plasma renin activity and Homeostasis model assessment-insulin resistance (HOMA-IR. Arterial elasticity was evaluated using pulse wave contour analysis (HDI CR 2000, Eagan, Minnesota. Results Antioxidant-treated patients exhibited significant increases in large arterial elasticity index (LAEI as well as small arterial elasticity index (SAEI. A significant decline HbA1C and a significant increase in HDL-cholesterol were also observed. In the placebo group, significant changes in LAEI, SAEI or metabolic measures were not observed. Conclusions Antioxidant supplementation significantly increased large and small artery elasticity in patients with multiple cardiovascular risk factors. This beneficial vascular effect was associated with an improvement in glucose and lipid metabolism as well as decrease in blood pressure.

    2017-01-01

    Background Chronic liver scarring from any cause leads to cirrhosis, portal hypertension, and a progressive decline in renal blood flow and renal function. Extreme renal vasoconstriction characterizes hepatorenal syndrome, a functional and potentially reversible form of acute kidney injury in patients with advanced cirrhosis, but current therapy with systemic vasoconstrictors is ineffective in a substantial proportion of patients and is limited by ischemic adverse events. Serelaxin (recombinant human relaxin-2) is a peptide molecule with anti-fibrotic and vasoprotective properties that binds to relaxin family peptide receptor-1 (RXFP1) and has been shown to increase renal perfusion in healthy human volunteers. We hypothesized that serelaxin could ameliorate renal vasoconstriction and renal dysfunction in patients with cirrhosis and portal hypertension. Methods and findings To establish preclinical proof of concept, we developed two independent rat models of cirrhosis that were characterized by progressive reduction in renal blood flow and glomerular filtration rate and showed evidence of renal endothelial dysfunction. We then set out to further explore and validate our hypothesis in a phase 2 randomized open-label parallel-group study in male and female patients with alcohol-related cirrhosis and portal hypertension. Forty patients were randomized 1:1 to treatment with serelaxin intravenous (i.v.) infusion (for 60 min at 80 μg/kg/d and then 60 min at 30 μg/kg/d) or terlipressin (single 2-mg i.v. bolus), and the regional hemodynamic effects were quantified by phase contrast magnetic resonance angiography at baseline and after 120 min. The primary endpoint was the change from baseline in total renal artery blood flow. Therapeutic targeting of renal vasoconstriction with serelaxin in the rat models increased kidney perfusion, oxygenation, and function through reduction in renal vascular resistance, reversal of endothelial dysfunction, and increased activation of the

    The liver is an important organ with specific functions that influence directly on the nutritional and physiological status of every person. At the presence of any illness or injury in this organ, liver cirrhosis is always its final phase. In this pathology, patients present carbohydrate utilization and storage diminishment, as well as protein and fat catabolism increase. This situation, plus a low ingest and a bad nutrient absorption, results in a high prevalence of malnutrition. Many studies prove the importance of an opportune nutritional treatment in these patients, bringing general benefits and improving their quality of life. It's important to considerate the possible nutritional risks and deficiencies that could appear in the course of the cirrhosis to take opportune actions. The nutritional assessment and treatment is transcendental both in compensated phase (without complications) and in decompensated phase (with complications) of the illness.

    Fifteen patients with Laennec's cirrhosis underwent orthotopic liver transplantation between 1963 and the end of 1979. The first eight patients died perioperatively or within two months, but four of the next seven patients had long survival; three are still alive after 11 to 14 years. After the introduction of cyclosporine therapy, 41 more patients with alcoholic cirrhosis were treated with liver transplantation from 1980 to June 1987. The one-year survival is 73.2%, and, after one to three years, 28 (68%) of the recipients are living. Of the 35 patients in the combined old and new series who lived for six months or longer, only two returned to alcohol abuse. Social and vocational rehabilitation has been the rule in these recipients who were selected primarily because of urgency of need, because they or their families insisted on treatment, and because they and their families thereby committed themselves to long-standing programs of alcoholism care.

    AIM: It is known that toxoplasmosis rarely leads to various liver pathologies, most common of which is granulomatose hepatitis in patients having normal immune systems. Patients who have cirrhosis of the liver are subject to a variety of cellular as well as humoral immunity disordes. Therefore, it may be considered that toxoplasmosis can cause more frequent and more severe diseases in patients with cirrhosis and is capable of changing the course of the disease. The aim of this study was to investigate the frequency of METHODS: Serum samples were taken from 108 patients with cirrhosis under observation in the Hepatology Polyclinic of the Gastroenterology Clinic, and a control group made up of 50 healthy blood donors. IFAT and ELISA methods were used to investigate the IgG and IgM antibodies, which had developed from these sera.RESULTS: Toxoplasma IgG and IgM antibody positivity was found in 74 (68.5%) of the 108 cirrhotic patients and 24 (48%) of the 50 people in the control group. The difference between them was significant (P<0.05).CONCLUSION: In conclusion, it was found that the toxoplasma sero-prevalence in the cirrhotic patients in this study was higher. Cirrhotic patients are likely to form a toxoplasma risk group, More detailed studies are needed on this subject.

    Full Text Available Sensitive and specific detection of liver cirrhosis is an urgent need for optimal individualized management of disease activity. Substantial studies have identified circulation miRNAs as biomarkers for diverse diseases including chronic liver diseases. In this study, we investigated the plasma miRNA signature to serve as a potential diagnostic biomarker for silent liver cirrhosis.A genome-wide miRNA microarray was first performed in 80 plasma specimens. Six candidate miRNAs were selected and then trained in CHB-related cirrhosis and controls by qPCR. A classifier, miR-106b and miR-181b, was validated finally in two independent cohorts including CHB-related silent cirrhosis and controls, as well as non-CHB-related cirrhosis and controls as validation sets, respectively.A profile of 2 miRNAs (miR-106b and miR-181b was identified as liver cirrhosis biomarkers irrespective of etiology. The classifier constructed by the two miRNAs provided a high diagnostic accuracy for cirrhosis (AUC = 0.882 for CHB-related cirrhosis in the training set, 0.774 for CHB-related silent cirrhosis in one validation set, and 0.915 for non-CHB-related cirrhosis in another validation set.Our study demonstrated that the combined detection of miR-106b and miR-181b has a considerable clinical value to diagnose patients with liver cirrhosis, especially those at early stage.

    An iliopsoas hematoma can occur either spontaneously or secondary to trauma or bleeding tendency due to hemophilia and anticoagulant therapy. Although liver cirrhosis is commonly associated with coagulopathy, iliopsoas hematoma is very rare. We herein, present a case of bilateral iliopsoas hematoma in a patient with alcoholic cirrhosis, and review the literature on muscle hematoma associated with cirrhosis. A 56-year-old man with alcoholic cirrhosis was admitted in a state of shock with anemia. The cause of anemia could not be detected, and the patient was treated conservatively. The site of bleeding was not detected with either gastroduodenal endoscopy or upper abdominal computed tomography, the latter of which did not include the iliopsoas muscle. He died on the 10th day of admission and bilateral iliopsoas hematomas were found on autopsy. An iron stain was positive in the iliopsoas muscle. Eight cases of muscle hematoma associated with cirrhosis, including the present case, were found in a review of the literature. Four of these cases involved the rectus abdominis muscle, 3 involved the iliopsoas muscle and 1 involved combined muscles. Alcoholic cirrhosis accounted for 75% of the cases. One case (12.5%) was associated with virus-related cirrhosis, and another with combined virus-and alcohol-related cirrhosis. The mortality rate was 75% despite early diagnosis and low risk scores for cirrhosis. Muscle hematoma in patients with cirrhosis isclosely related to alcoholism, and the mortality rate of the condition is extremely high. In conclusion, muscle hematoma should be recognized as an important complication of cirrhosis.

    Full Text Available The incidence of cirrhosis and primary hepatic carcinoma in the autopsy material is studied. in 4389 autopsies performed, during the last 9 years we found 134 (3% cases of cirrhosis and 24 (0.5% cases of primary hepatic carcinoma. The majority of the patients were from NorthWest and west part of the city. of the 134 cases of cirrhosis 90 correspond to the portal type, 24 to the post-necrotic type, 12 to the biliary cirrhosis, 6 to the post-hepatitis cirrhosis and two cardiac cisrhosis. 19 of our 134 cases of cirrhosis, occured in children between the age of 4months to 13 years. The liver of the 90 cases diagnosed, Portal cirrhosis were characterized grossely by weights from 510-2800 Gr and fine uniformly nodular surface. Micscopically there was marked, fatty change of hepatic cells, focal and spotty necrosis and delicated fibrillary tongue, interconnecting portal spaces. of the 24 cases post-necrotic cirrhosis 4 had had (26% an antecedent jaundice. The liver ranged, from 700-2500 gr., presenting broad scarring and coars nodules. In bur six cases, Post-hepatitic cirrhosis, the liver were redish brown, and presented uniform nodules, 0,5 to 1.5 Cm. in diameter. Liver weights varried form 850 to 1200 Gr. Microscopically 17 cases of carcinoma were hepato-carcinoma, two presented mixed structures of hepatoma and 5 cases were cholangio Carcinoma. Six of hepatomas showed previous portal cirrhosis and one mixed carcinoma showed previous portal cirrhosis.

    Full Text Available Liver cirrhosis is characterized by a severe acquired reduction of LAL-activity, the precise causes and consequences of which need to be further addressed. DBS-determined lysosomal enzyme activities seem to be affected by white blood cell and platelet counts, and the specificity of these tests can be reduced when applied to determined populations, such as cirrhotics.

  18. Recapitulation of Developing Artery Muscularization in Pulmonary Hypertension

    2014-03-01

    Full Text Available Excess smooth muscle accumulation is a key component of many vascular disorders, including atherosclerosis, restenosis, and pulmonary artery hypertension, but the underlying cell biological processes are not well defined. In pulmonary artery hypertension, reduced pulmonary artery compliance is a strong independent predictor of mortality, and pathological distal arteriole muscularization contributes to this reduced compliance. We recently demonstrated that embryonic pulmonary artery wall morphogenesis consists of discrete developmentally regulated steps. In contrast, poor understanding of distal arteriole muscularization in pulmonary artery hypertension severely limits existing therapies that aim to dilate the pulmonary vasculature but have modest clinical benefit and do not prevent hypermuscularization. Here, we show that most pathological distal arteriole smooth muscle cells, but not alveolar myofibroblasts, derive from pre-existing smooth muscle. Furthermore, the program of distal arteriole muscularization encompasses smooth muscle cell dedifferentiation, distal migration, proliferation, and then redifferentiation, thereby recapitulating many facets of arterial wall development.

    To provide an overview of the medical literature on giant splenic artery aneurysm (SAA).The PubMed, Medline, Google Scholar, and Google databases were searched using keywords to identify articles related to SAA. Keywords used were splenic artery aneurysm, giant splenic artery aneuryms, huge splenic artery aneurysm, splenic artery aneurysm rupture, and visceral artery aneurysm. SAAs with a diameter ≥5 cm are considered as giant and included in this study. The language of the publication was not a limitation criterion, and publications dated before January 15, 2015 were considered.The literature review included 69 papers (62 fulltext, 6 abstract, 1 nonavailable) on giant SAA. A sum of 78 patients (50 males, 28 females) involved in the study with an age range of 27-87 years (mean ± SD: 55.8 ± 14.0 years). Age range for male was 30-87 (mean ± SD: 57.5 ± 12.0 years) and for female was 27-84 (mean ± SD: 52.7 ± 16.6 years). Most frequent predisposing factors were acute or chronic pancreatitis, atherosclerosis, hypertension, and cirrhosis. Aneurysm dimensions were obtained for 77 patients with a range of 50-300 mm (mean ± SD: 97.1 ± 46.0 mm). Aneurysm dimension range for females was 50-210 mm (mean ± SD: 97.5 ± 40.2 mm) and for males was 50-300 mm (mean ± SD: 96.9 ± 48.9 mm). Intraperitoneal/retroperitoneal rupture was present in 15, among which with a lesion dimension range of 50-180 mm (mean ± SD; 100 ± 49.3 mm) which was range of 50-300 mm (mean ± SD: 96.3 ± 45.2 mm) in cases without rupture. Mortality for rupture patients was 33.3%. Other frequent complications were gastrosplenic fistula (n = 3), colosplenic fistula (n = 1), pancreatic fistula (n = 1), splenic arteriovenous fistula (n = 3), and portosplenic fistula (n = 1).

  6. NT pro BNP plasma level and atrial volume are linked to the severity of liver cirrhosis.

    Directory of Open Access Journals (Sweden)

    Anna Licata

    Full Text Available BACKGROUND AND AIMS: Plasma levels of NT-pro-BNP, a natriuretic peptide precursor, are raised in the presence of fluid retention of cardiac origin and can be used as markers of cardiac dysfunction. Recent studies showed high levels of NT pro BNP in patients with cirrhosis. We assessed NT pro-BNP and other parameters of cardiac dysfunction in patients with cirrhosis, with or without ascites, in order to determine whether the behaviour of NT pro BNP is linked to the stage of liver disease or to secondary cardiac dysfunction. METHODS: Fifty eight consecutive hospitalized patients mostly with viral or NAFLD-related cirrhosis were studied. All underwent abdominal ultrasound and upper GI endoscopy. Cardiac morpho-functional changes were evaluated by echocardiography and NT-pro-BNP plasma levels determined upon admission. Twenty-eight hypertensive patients, without evidence of liver disease served as controls. RESULTS: Fifty eight cirrhotic patients (72% men with a median age of 62 years (11% with mild arterial hypertension and 31% with type 2 diabetes had a normal renal function (mean creatinine 0.9 mg/dl, range 0.7-1.06. As compared to controls, cirrhotic patients had higher NT pro-BNP plasma levels (365.2±365.2 vs 70.8±70.6 pg/ml; p<0.001. Left atrial volume (LAV (61.8±26.3 vs 43.5±14.1 ml; p = 0.001, and left ventricular ejection fraction (62.7±6.9 vs. 65.5±4%,; p = 0.05 were also altered in cirrhotic patients that in controls. Patients with F2-F3 oesophageal varices as compared to F0/F1, showed higher e' velocity (0.91±0.23 vs 0.66±0.19 m/s, p<0.001, and accordingly a higher E/A ratio (1.21±0.46 vs 0.89±0.33 m/s., p = 0.006. CONCLUSION: NT-pro-BNP plasma levels are increased proportionally to the stage of chronic liver disease. Advanced cirrhosis and high NT-pro-BNP levels are significantly associated to increased LAV and to signs of cardiac diastolic dysfunction. NT pro-BNP levels could hence be an useful prognostic

  7. Risk factors for nonalcoholic steatohepatitis in cryptogenic cirrhosis

    2012-12-01

    Full Text Available CONTEXT: In about 10% of patients with chronic liver disease, it is not possible to identify an etiologic factor. These cases are called cryptogenic cirrhosis. Currently, nonalcoholic steatohepatitis (NASH is being considered as a possible etiologic factor for a significant segment of patients that presents with cryptogenic cirrhosis. OBJECTIVE: To estimate the prevalence of risk factors for NASH in patients with cryptogenic cirrhosis, in order to verify if there is a causal relationship between them. METHOD: Cross-sectional study, with evaluation of the demographic and laboratorial data of patients with cryptogenic cirrhosis. They were compared with data obtained from a group with NASH and a group with alcoholic and/or hepatitis C (HCV cirrhosis. RESULTS: Forty seven patients with cryptogenic cirrhosis were evaluated, 47 with NASH and 196 with HCV and/or alcoholic cirrhosis. The mean age of patients with cryptogenic cirrhosis was 52 years, while in those with NASH it was 46.4 years (P = 0,041. The group with cryptogenic cirrhosis had 23 female and 24 male patients. Of the patients who presented with NASH, 68.1% were female. Of the patients who presented with alcoholic/HCV cirrhosis, 64.8% were male. There were no statistically significant differences between the groups. In cryptogenic cirrhosis patients, the following prevalences could be observed: impaired fasting glycemia - 68.2%; obesity - 27.5%; total hypercholesterolemia - 27.9%; low HDL levels - 58.1% (women - 81%; men - 36.4%; hypertriglyceridemia - 16.3%. The results seen in cryptogenic cirrhosis patients showed statistical similarity with the results of the NASH group regarding fasting glycemia (62.8% and male HDL levels (53.8%. The comparison with the alcoholic/HCV cirrhosis group showed statistical differences regarding fasting glycemia (45.2%, hypercholesterolemia (13.3% and female HDL levels (50.8%.

    2015-01-01

    BACKGROUND & AIMS: Alcohol is the main contributing factor of alcoholic cirrhosis, but less is known about the significance of drinking pattern. METHODS: We investigated the risk of alcoholic cirrhosis among 55,917 participants (aged 50-64 years) in the Danish Cancer, Diet, and Health study (1993......-2011). Baseline information on alcohol intake, drinking pattern, and confounders was obtained from a questionnaire. Follow-up information came from national registers. We calculated hazard ratios (HRs) for alcoholic cirrhosis in relation to drinking frequency, lifetime alcohol amount, and beverage type. RESULTS......: We observed 257 and 85 incident cases of alcoholic cirrhosis among men and women, respectively, none among lifetime abstainers. In men, HR for alcoholic cirrhosis among daily drinkers was 3.65 (95% CI: 2.39; 5.55) compared to drinking 2-4 days/week. Alcohol amount in recent age periods (40-49 and 50...

  11. Primary Biliary Cirrhosis and Hemolytic Anemia Confusing Serum Bilirubin Levels

    Directory of Open Access Journals (Sweden)

    M Brackstone

    2000-01-01

    Full Text Available Hemolysis is observed in more than 50% of patients with cirrhosis. However, there has been little documention of the association of primary biliary cirrhosis with autoimmune hemolytic anemia. Two cases, found within a single practice, of primary biliary cirrhosis coexisting with autoimmune hemolysis and a third case coexisting with hereditary spherocytosis are presented. Anemia in such patients is commonly attributed to chronic disease, and hyperbilirubinemia is attributed to primary biliary cirrhosis. These patients were considered for liver transplantation until the diagnosis of a comorbid hemolytic process was established. This association may be more prevalent than previously recognized. A diagnosis of comorbid hemolysis must always be considered in context with anemia and serum bilirubin levels that rise out of proportion to the severity of the primary biliary cirrhosis.

  13. Treatment of Hepatitis B in Decompensated Liver Cirrhosis

    Directory of Open Access Journals (Sweden)

    Richard Guan

    2011-01-01

    Full Text Available Chronic hepatitis B infection progresses from an asymptomatic persistently infected state to chronic hepatitis, cirrhosis, decompensated liver disease, and/or hepatocellular carcinoma. About 3% of patients with chronic hepatitis develop cirrhosis yearly, and about 5% of individuals with hepatitis B cirrhosis become decompensated annually. The outcome for patients with decompensated cirrhosis is bleak. Lamivudine, the first oral antiviral agent available for hepatitis B treatment is safe and effective and can improve or stabilize liver disease in patients with advanced cirrhosis and viraemia. Viral resistance restricts its prolonged use. Entecavir and tenofovir are newer agents with excellent resistance profile to date. These and some other antiviral agents are being investigated for optimal use in this rather challenging patient group.

    2016-01-01

    The intestinal microbiome (IM) is altered in patients with cirrhosis, and emerging literature suggests that this impacts on the development of complications. The PubMed database was searched from January 2000 to May 2015 for studies and review articles on the composition, pathophysiologic effects and therapeutic modulation of the IM in cirrhosis. The following combination of relevant text words and MeSH terms were used, namely intestinal microbiome, microbiota, or dysbiosis, and cirrhosis, encephalopathy, spontaneous bacterial peritonitis, hepatorenal syndrome, variceal bleeding, hepatopulmonary syndrome, portopulmonary hypertension and hepatocellular carcinoma. The search results were evaluated for pertinence to the subject of IM and cirrhosis, as well as for quality of study design. The IM in cirrhosis is characterized by a decreased proportion of Bacteroides and Lactobacilli, and an increased proportion of Enterobacteriaceae compared to healthy controls. Except for alcoholic cirrhosis, the composition of the IM in cirrhosis is not affected by the etiology of the liver disease. The percentage of Enterobacteriaceae increases with worsening liver disease severity and decompensation and is associated with bacteremia, spontaneous bacterial peritonitis and hepatic encephalopathy. Lactulose, rifaximin and Lactobacillus-containing probiotics have been shown to partially reverse the cirrhosis associated enteric dysbiosis, in conjunction with improvement in encephalopathy. The IM is altered in cirrhosis, and this may contribute to the development of complications associated with end-stage liver disease. Therapies such as lactulose, rifaximin and probiotics may, at least partially, reverse the cirrhosis-associated changes in the IM. This, in turn, may prevent or alleviate the severity of complications. PMID:27721918

    1980-01-01

    23 patients with liver cirrhosis of diverse etiology and of different activity levels and grades of compensation of the portal circulation were examined with regard to the systemic endotoxinaemia. The endotoxin was determined using the Limulus-Amoebocyte-Lysat-test. Endotoxin was traceable in the venous blood of 7 out of 23 patients (= 30,4%). No relation was found between endotoxaemia and the activity or grade of severity of liver cirrhosis; nor were there any accumulation of endotoxinaemia in patients with collateral circulation or portal decompensation. Consequently, as a result of our findings, the prognostic value of the symptom endotoxinaemia remains debatable, then endotoxinaemia does not always mean endotoxicosis. Particularly high immunoglobulin concentration and low albumin values in serum of endotoxin-positive cirrhotics indicate a "spillovet" of antigen substances and also of endotoxines in the body circulation resulting from insufficiency of the liver-RHS. Parallel analysis of microbian small bowel flora in 10 patients indicate that coli-dysbiosis appears to play a role in the development of systemic endoxinaemia, although the latter was also traceable in borderline cases of eubiosis/dysbiosis. Our findings strengthen the view that it is not possible to simply translate the findings in animals on to human liver diseases. Quite a number of the mechanisms being discussed are still with uncleared details and they give only a blurred picture of the pathophysiology of endotoxinaemia.

  17. Bacterial infections in patients with liver cirrhosis

    Directory of Open Access Journals (Sweden)

    Giacomo Zaccherini

    2011-07-01

    Full Text Available Bacterial infections represent a frequent complication of liver cirrhosis carrying a significantly greater risk of morbidity and mortality as compared to that observed in non-cirrhotic patients. Such unfavourable prognosis is related to the systemic complications (liver and renal failure, shock, coagulopathy, multiple organ failure induced by a series of pro-inflammatory and immunological systems which are activated by bacteria and their pathogenetic products.The epidemiology of bacterial infections in cirrhosis has changed in the last years with a marked increase of Gram+ infections and the emergence of multi-resistant bacteria.The severity of liver disease represents the major clinical factor predisposing to bacterial infections, which are asymptomatic or paucisymptomatic at presentation in almost half of the cases. Aim of this review is to summarise the clinical and therapeutic aspects of bacterial infections in cirrhotic patients. The most common sites of infection are the urinary tract, ascites, blood, lungs and soft tissues.Beside antibiotics, it has been proposed the administration of human albumin to prevent the development of renal failure in patients with spontaneous bacterial peritonitis and, more recently, the use of hydrocortisone to treat cirrhotic patients with septic shock.

  18. [Environmental factors and primary biliary cirrhosis].

    2016-07-20

    The complex interplay between immune factors and genetic susceptibility plays an essential role in autoimmune diseases. This is especially true for primary biliary cirrhosis (PBC). PBC is an autoimmune cholestatic liver disease characterized by the destruction of the small intrahepatic bile ducts and the presence of high-titer antimitochondrial antibodies (AMA). Among the currently known risk factors, genetic predisposition remains to be the dominant one. However, it is insufficient to explain the different geographic distributions of PBC and the incomplete concordance in identical twins. This suggests an association between specific environmental factors and the development of PBC. Nevertheless, a clear and rational association of environmental factors with primary biliary cirrhosis has not yet been fully elucidated. Our current understanding of the environmental triggers of PBC is limited to numerous suspected factors involved in its development, such as xenobiotics, electrophilic drugs, infection, and other physical, chemical, and even biological factors. Although the factors leading to the breakdown of immune tolerance in PBC are still largely unknown, related geoepidemiological studies may help us better understand the impact of the environment. In addition, a better understanding of the interplay between environmental factors and PBC is the critical step toward improving our management and control of PBC and autoimmunity in general.

    The cause in 10 - 20% cases of liver cirrhosis (LC) cannot be elucidated, and are thus termed cryptogenic. Pulmonary arteriovenous malformations (PAVMs) are relatively rare, but the most common anomaly involving the pulmonary tree. Although the rare correlation between LC and PAVM is well-known, there have been no reports of PAVMs occurring in cryptogenic LC. We report a case of PAVM that occurred in cryptogenic liver cirrhosis in a 3 years old male child. The child presented with complaints of malena, hematemesis and variceal bleed. The examination revealed a child with respiratory distress, irritability, tachycardia, clubbing and abdominal distention. He was worked up for recurrent variceal bleeding secondary to portal hypertension but the oxygen saturation during hospital stay kept deteriorating. The diagnosis of hepatopulmonary syndrome as the cause of persistent hypoxemia in the absence of other cardio-pulmonary causes was then made by enhanced echocardiogram using agitated saline. He improved significantly after liver transplantation performed abroad. At a 6 months follow-up, the child was stable with no evidence of intrapulmonary shunting on repeat echo.

    Determining the prognosis of cirrhotic patients is not aneasy task. Prognostic scores, like Child-Pugh and Modelof End-stage Liver Disease scores, are commonly usedby hepatologists, but do not always reflect superimposedevents that may strongly influence the prognosis.Among them, bacterial intestinal translocation is a keyphenomenon for the development of cirrhosis-relatedcomplications. Several biological variables (C-reactiveprotein, serum free cortisol, copeptin, von Willebrandfactor antigen) are surrogates of "inflammatory stress"and have recently been identified as potential prognosticmarkers in cirrhotic patients. Most of these abovementioned markers were investigated in pilot studieswith sometimes a modest sample size but allow us tocatch a glimpse of the pathophysiological mechanismsleading to the worsening of cirrhosis. These new datashould generate further well-designed studies to betterassess the benefit for liver function of preventingintestinal bacterial translocation and microvascularthrombosis. The control of infection is vital and amongall actors of immunity, vitamin D also appears to actas an anti-infective agent and therefore has probably aprognostic value.

    Radiofrequency-powered, thermal balloon angioplasty is a new technique that enhances luminal dilatation with less dissection than conventional angioplasty. The purpose of this study was to assess the effect of radiofrequency heating of balloon fluid on the pressure-volume mechanics of in vitro balloon angioplasty and to determine the histologic basis for thermal-induced compliance changes. In vitro, radiofrequency-powered, thermal balloon angioplasty was performed on 46 paired iliac segments freshly harvested from 23 nonatherosclerotic pigs. Balloon inflations at 60 degrees C were compared to room temperature inflations in paired arterial segments. Intraballoon pressure and volume were recorded during each inflation as volume infusion increased pressure over a 0 to 10 atm range. Pressure-volume compliance curves were plotted for all dilatations. Six segments were stained to assess the histologic abnormalities associated with thermal compliance changes. Radiofrequency heating acutely shifted the pressure-volume curves rightward in 20 of 23 iliac segments compared to nonheated controls. This increase in compliance persisted after heating and exceeded the maximum compliance shift caused by multiple nonheated inflations in a subset of arterial segments. Histologically, heated segments showed increased thinning and compression of the arterial wall, increased medial cell necrosis and altered elastic tissue fibers compared to nonheated specimens. In conclusion, radiofrequency heating of intraballoon fluid to 60 degrees C acutely increases vascular compliance during in vitro balloon angioplasty of nonatherosclerotic iliac arteries. The increased compliance persists after heating and can be greater than the compliance shifts induced by multiple conventional dilatations. Arterial wall thinning and irreversible alteration of elastic tissue fibers probably account for thermal compliance changes.

    Exogenous treatment with the naturally occurring peptide relaxin increases arterial compliance and reduces vascular stiffness. In contrast, relaxin deficiency reduces the passive compliance of small renal arteries through geometric and compositional vascular remodeling. The role of endogenous relaxin on passive mechanical wall properties in other vascular beds is unknown. Importantly, no studies have investigated the effects of aging in arteries of relaxin-deficient mice. Therefore, we tested the hypothesis that mesenteric and femoral arteries stiffen with aging, and this is exacerbated with relaxin deficiency. Male wild-type (Rln (+/+)) and relaxin knockout (Rln (-/-)) mice were aged to 3, 6, 12, 18, and 23 months. Passive mechanical wall properties were assessed by pressure myography. In both genotypes, there was a significant increase in circumferential stiffening in mesenteric arteries with aging, whereas in the femoral artery, aging reduced volume compliance. This was associated with a reduced ability of the artery to lengthen with aging. The predominant phenotype observed in Rln (-/-) mice was reduced volume compliance in young mice in both mesenteric and femoral arteries. In summary, aging induces circumferential stiffening in mesenteric arteries and axial stiffening in femoral arteries. Passive mechanical wall properties of Rln (-/-) mouse arteries predominantly differ at younger ages compared with Rln (+/+) mice, suggesting that a lack of endogenous relaxin only has a minor effect on vascular aging.

    A 79-year-old female patient with hepatitis C virusrelated liver cirrhosis was diagnosed as having hepatocellular carcinoma (HCC) with a diameter of 2.0 cm. She refused therapy for HCC. Nine months after the diagnosis, she developed dermatomyositis when the HCC enlarged to a diameter of 6.0 cm. She underwent therapy for dermatomyositis, and then transcatheter arterial chemoembolization for HCC. Although the manifestations of dermatomyositis improved and entire tumor necrosis was achieved, she died of pneumonia 2 mo after the treatment of HCC. HCC and/or chronic hepatitis C virus infection might be involved in the pathogenesis of dermatormyositis.

    Full Text Available Peritoneoscopic findings of 39 patients with alcoholic liver cirrhosis (ALC were compared with those of 95 patients with non-alcoholic liver cirrhosis (NALC. They were selected from 245 patients with liver cirrhosis subjected to peritoneoscopy in the 7 year period from 1975 to 1981. Out of the 95 NALC patients, 24 had hepatitis B surface antigen. The ALC patients had nodules which varied in size (61%, large depressions (69%, and a markedly rounded edge of the liver (33% more often than NALC patients (18, 43 and 3%, respectively. Nodularity differed between the right and left lobes in ALC (41% more often than in NALC (16%. Interstitial reddish markings and patchy nodules were, however, more frequent in NALC (51 and 28%, respectively than in ALC (8 and 5%, respectively. Lymphatic vesicles were observed both in ALC (85% and NALC (78%. In conclusion, the peritoneoscopic features which suggested ALC were the coexistence of nodules of various sizes, large depressions and a markedly dull edge of the liver. Interstitial reddish markings and patchy nodules were more indicative of NALC than ALC.

    Malnutrition is very common in patients with liver cirrhosis and includes especially protein-calorie malnutrition. The pathophysiological reasons vary and are caused by metabolic modifications and characteristics of enteral absorption and digestion cause by the cirrhosis. Malnutrition contributes to overall mortality and complication rate of the chronic liver disease. An adequate daily energy and protein supply should be ensured in patients with liver cirrhosis, which is higher than that in the normal population, because of higher amino-acid turnover. Ascites may benefit from daily low-salt fluid intake. Nutritional substitution of vitamins and trace elements is indicated when symptoms of deficiency occur.

    AIM: To assess the value of gray scale (GS) and colour Doppler ultrasonography (CDU) in differentiating the progression of chronic viral hepatitis (CVH) and compensated liver cirrhosis (CIR).METHODS: Seventy-two patients and 32 normal individuals who were used as controls were studied. Forty-four patients suffered from CVH and 28 from CIR. All patients were underwent to liver biopsy. Multiple qualitative and quantitative variables were studied in liver, portal vein (PV), hepatic artery (HA) and spleen with GS and CDU. On the basis of the obtained CDU data, several known indexes were calculated. In addition, alternative indices [PV diameter (D)/time average mean velocity (Vtam), HA/PV Vtam ratio J were calculated and studied.RESULTS: ROC analysis showed that PV congestion index, PV D/VTAM and HA/PV VTAM indices had the best sensitivity and specificity in discriminating CVH from CIR. Stepwise discriminant analysis showed that 88.9% of the originally grouped cases could be correctly classified by the three qualitative and four quantitative variables selected as statistically significant predictors. Among the CVH patients who underwent to biopsy, statistically significant changes were found in those at fibrosis stage 5 compared to fibrosis stages 1-4.CONCLUSION: Simple GS and CDU parameters discri-minate CVH from CIR. The alternative Doppler indexes can accurately differentiate chronic virus hepatitis from cirrhosis. These indexes can be used in monitoring chronic virus hepatitis and avoiding unnecessary biopsies.

    AIM: Hepatocelluar adenoma (HCA) and adenomatous hyperplasia (AH) are rare benign tumors of the liver. HCA is usually found in women who use oral contraceptives. AH usually occurs in patients with liver cirrhosis. Both tumors have potential for malignant transformation.METHODS: We described a male adult with chronic liver disease (CLD) who had been known to be a hepatitis B carrier (HBV) for years. He was found to have a spaceoccupying lesion with a suspicion of hepatocellular carcinoma (HCC) by abdominal ultrasonography. His α-fetoprotein (AFP)was normal. Angiographic findings were consistent with the diagnosis of HCC, he wished to avoid an operation, was treated with transcatheter hepatic arterial embolization.RESULTS: He subsequently consented to surgery, and a right lobectomy was performed. The liver pathology disclosed HCA with nuclear dysplasia and post-embolization effects.In addition, there were multiple small foci of AH with nuclear dysplasia in the resected liver. Although he had some focal areas of cirrhosis-like change or post-embolization effect,the AH was associated only with normal liver tissue.CONCLUSION: This case confirms that HCA and AH may resemble HCC on imaging studies, and that AH may occur in CLD in the absence of cirrhotic change.

However, studies of arterial function in vegetarians are limited.Methods: This study investigated arterial function in vegetarianism by comparing 49 healthy postmenopausal vegetarians with 41 age-matched omnivores. The arterial function of the common carotid artery was assessed by carotid duplex, while the pulse dynamics method was used to measure brachial artery distensibility (BAD, compliance (BAC, and resistance (BAR. Fasting blood levels of glucose, lipids, lipoprotein (a, high-sensitivity C-reactive protein, homocysteine, and vitamin B12 were also measured.Results: Vegetarians had significantly lower serum cholesterol, high-density and low-density lipoprotein, and glucose compared with omnivores. They also had lower vitamin B12 but higher homocysteine levels. Serum levels of lipoprotein (a and high-sensitivity C-reactive protein were no different between the two groups. There were no significant differences in carotid beta stiffness index, BAC, and BAD between the two groups even after adjustment for associated covariates. However, BAR was significantly lower in vegetarians than in omnivores. Multiple linear regression analysis revealed that age and pulse pressure were two important determinants of carotid beta stiffness index and BAD. Vegetarianism is not associated with better arterial elasticity.Conclusion: Apparently healthy postmenopausal vegetarians are not significantly better in terms of carotid beta stiffness index, BAC, and BAD, but have significantly decreased BAR than

    professionals know the patients’ difficulties to be compliant with anti-hypertensive treatment so they can try correcting the problems together with the patient for a better control of HBP. It has to be pointed out that the trust resulting from a good doctor/patient relationship contributes greatly to a better treatment compliance of the patient.

    A hipertensão arterial sistêmica (HAS é uma doença crônica, cujo controle é essencial para a prevenção de complicações, em longo prazo, relacionadas à morbidade e à mortalidade cardiovascular e cerebral, dentre outras. O tratamento da HAS baseia-se em medidas não-farmacológicas e farmacológicas. Considerase adesão a um tratamento o grau de coincidência entre a orientação médica e o comportamento do paciente. Na Unidade de Saúde Parque dos Maias, observa-se a dificuldade na manutenção da pressão arterial dos hipertensos, de forma continuada, que pode estar relacionada à falta de adesão destes pacientes ao tratamento. O objetivo do estudo é avaliar os fatores envolvidos na dificuldade de adesão ao tratamento anti-hipertensivo sob o ponto de vista do paciente.

    Endoscopic epinephrine injection is relatively easy, quick and inexpensive. Furthermore, it has a low rate of complications, and it is widely used for the management of nonvariceal upper gastrointestinal bleeding. There have been several case reports of gastric ischemia after endoscopic injection therapy. Inadvertent intra-arterial injection may result in either spasm or thrombosis, leading to subsequent tissue ischemia or necrosis, although the stomach has a rich vascular supply and the vascular reserve of the intramural anastomosis. In addition to endoscopic injection therapy, smoking, hypertension and atherosclerosis are risk factors of gastric ischemia. We report a case of gastric ischemia after submucosal epinephrine injection in a 51-year-old woman with hypertension and liver cirrhosis. PMID:23372366

A comparative analysis of immunological data was performed in the patients with HBV-induced liver cirrhosis, and in a group of patients with acute and chronic viral hepatitis B (AVHB, CVHB. Activation of B cell immune compartment (increase in CD22+ lymphocytes and IL4, circulating immune complexes in blood was demonstrated in patients with liver cirrhosis, being also associated with increased numbers of CD16+ lymphocytes and T-cell deficiency. It was revealed that the differences are most expressed upon comparison of immunologic data from the patients with liver cirrhosis, and AVHB followed by clearance of the virus. When comparing these groups, the differences in immunological state between the patients with liver cirrhosis and CVHB did not depend on the phase of viral replication or integration.

  1. Prediction of liver cirrhosis, using diagnostic imaging tools

    Institute of Scientific and Technical Information of China (English)

    2015-01-01

    Early diagnosis of liver cirrhosis is important. Ultrasoundguidedliver biopsy is the gold standard for diagnosis ofliver cirrhosis. However, its invasiveness and samplingbias limit the applicability of the method. Basic imagingfor the diagnosis of liver cirrhosis has developed overthe last few decades, enabling early detection ofmorphological changes of the liver by ultrasonography(US), computed tomography, and magnetic resonanceimaging (MRI). They are also accurate diagnosticmethods for advanced liver cirrhosis, for which earlydiagnosis is difficult. There are a number of ways tocompensate for this difficulty, including texture analysisto more closely identify the homogeneity of hepaticparenchyma, elastography to measure the stiffness andelasticity of the liver, and perfusion studies to determinethe blood flow volume, transit time, and velocity.Amongst these methods, elastography using US andMRI was found to be slightly easier, faster, and able toprovide an accurate diagnosis. Early diagnosis of livercirrhosis using MRI or US elastography is therefore arealistic alternative, but further research is still needed.

    Cryptogenic cirrhosis is a clinical entity which has the potential for better diagnosis of actual underlying maladies with future advancements in medicine. Current understanding of CC is rapidly undergoing transformation (Figures 1 & 2). In the light of available evidence of frequent disappearance of fat in NASH-associated cirrhosis, CC explants showing steatosis, allografts demonstrating the full blown recurrence of NASH in CC, and the association of CC with diabetes and obesity, suggests CC to be more proximately linked with NAS than believed until now (Figure 2). However, there are subsets of patients within CC that appear to emerge from other etiologies. With increasing clarity of NASH pathogenesis, a useful biomarker might soon be available. Advancements in diagnostics and our understanding of NASH are likely to elucidate NASH-associated cirrhosis as the predominant cause of cryptogenic cirrhosis.

    With the growing epidemic of obesity, the incidence of both nonalcoholic fatty liver disease (NAFL) and nonalcoholic steatohepatitis (NASH) is increasing. The intestinal microbiota differs between individuals who are obese or have normal body mass indices. Animal studies have shown increased intestinal permeability in NAFL, NASH, and cirrhosis. This increases the risk of oxidative and inflammatory injury to the liver from intestinal microbacteria. It may also increase the risk of fatty acid injury and fatty deposition. Bacterial translocation is associated with increased portal hypertension and hepatic encephalopathy in cirrhosis. By preventing bacterial adhesion and translocation, probiotics may have a role in the management of patients with NAFL, NASH, and cirrhosis. Multiple small studies have suggested that probiotics improve some of the clinical markers of activity in patients with NAFL and NASH. Controlled studies have also shown improved outcomes in patients with cirrhosis who were treated with probiotics.

    Hepatocellular carcinoma (HCC) accounts for about 90% of all malignant tumors of liver, ranking fifth in the worldwide incidence of malignant tumors and the third in fatality. More and more evidences suggest that cancer is a metabolic-related disease. From the analysis of recent clinical research data, we found that as the severity of the cirrhosis aggravated, patients with HCC and end-stage liver cirrhosis had a flat energy metabolism which was better than it in patients with simple end-stage liver cirrhosis. Based on these clinical phenomenon, the major aim of this study is to present a new hypothesis: "compensated liver function mechanism" for patients with HCC and liver cirrhosis, cancer cells may play a role to compensate liver function. In this study, we elaborated relevant content about this novel standpoint combined with tumor energy metabolism reprogramming mechanism and tumor cell origin as well as cell exchange mechanism.

    Non-invasive predictors of varices in cirrhosis would reduce the need for screening endoscopies. Platelet count and spleen size have been shown to be useful parameters, in mixed groups of cirrhotics with different aetiologies. We evaluated this in two homogeneous groups with cirrhosis due to hepatitis C and alcohol.Non-invasive predictors appear promising in the former group, but less so in the latter group.

    AIM: To investigate if sildenafil increases splanchnic blood flow and changes the hepatic venous pressure gradient (HVPG) in patients with cirrhosis. Phosphodiesterase type-5 inhibitors are valuable in the treatment of erectile dysfunction and pulmonary hypertension in patients with end-stage liver disease. However, the effect of phosphodiesterase type-5 inhibitors on splanchnic blood flow and portal hypertension remains essentially unknown. METHODS: Ten patients with biopsy proven cirrhosis (five females/five males, mean age 54±8 years) and an HVPG above 12 mmHg were studied after informed consent. Measurement of splanchnic blood flow and the HVPG during liver vein catheterization were done before and 80 min after oral administration of 50 mg sildenafil. Blood flow was estimated by use of indocyanine green clearance technique and Fick's principle, with correction for non-steady state. RESULTS: The plasma concentration of sildenafil was 222±136 ng/mL 80 min after administration. Mean arterial blood pressure decreased from 77±7 mmHg to 66±12 mmHg, P=0.003, while the splanchnic blood flow and oxygen consumption remained unchanged at 1.14±0.71 L/min and 2.3±0.6 mmol/ min, respectively. Also the HVPG remained unchanged (18±2 mmHg vs 16±2 mmHg) with individual changes ranging from-8 mmHg to+2 mmHg. In seven patients, HVPG decreased and in three it increased. CONCLUSION: In spite of arterial blood pressure decreases 80 min after administration of the phosphodiesterase type-5 inhibitor sildenafil, the present study could not demonstrate any clinical relevant influence on splanichnic blood flow, oxygen consumption or the HVPG.

    2016-01-01

    Hepatocellular carcinoma (HCC) is a common malignant tumor and many cases occur in patients with liver cirrhosis. Although liver transplantation is the most effective treatment option, hepatectomy is still the ifrst curative treatment option because liver transplantation is limited by the donors and high cost. In recent years, laparoscopic liver resection (LLR) has increasingly been performed in patients with liver cirrhosis, and has several advantages over open liver resection. Besides less pain and shorter hospital stay, LLR in patients with liver cirrhosis is also associated with lower incidences of postoperative liver failure and ascites because of greater preservation of collateral veins and less liver manipulation. With increasing experience, LLR for HCC located in segments 7 or 8 is now feasible, and anatomic LLR could be performed in patients with cirrhosis. Many comparative studies have shown that LLR is better than open liver resection in patients with liver cirrhosis in terms of a lower incidence of postoperative liver failure and similar patient survival. In conclusion, LLR is a promising treatment modality for HCC in patients with liver cirrhosis.

    Cirrhosis is a life-threatening condition that is generally attributed to overproduction of collagen fibers in the extracellular matrix that mechanically stiffens the liver. Chronic liver injury due to causes including viral hepatitis, inherited and metabolic liver diseases and external factors such as alcohol abuse can result in the development of cirrhosis. Progression of cirrhosis leads to hepatocellular dysfunction. While extensive studies to understand the complexity underlying liver fibrosis have led to potential application of anti-fibrotic drugs, no such FDA-approved drugs are currently available. Additional studies of hepatic fibrogenesis and cirrhosis primarily have focused on the extracellular matrix, while hepatocyte biomechanics has received limited attention. The role of hepatocyte biomechanics in liver cirrhosis remains elusive, and how the cell stiffness is correlated with biological functions of hepatocytes is also unknown. In this study, we demonstrate that the biomechanical properties of hepatocytes are correlated with their functions (e.g., glucose metabolism), and that hepatic dysfunction can be restored through modulation of the cellular biomechanics. Furthermore, our results indicate the hepatocyte functionality appears to be regulated through a crosstalk between the Rho and Akt signaling. These novel findings may lead to biomechanical intervention of hepatocytes and the development of innovative tissue engineering for clinical treatment to target liver cells rather than exclusively focusing on the extracellular matrix alone in liver cirrhosis.

    2012-12-01

    The use of compliance chambers in mock circulatory loop construction is the predominant means of simulating arterial compliance. Utilizing mock circulatory loops as bench test methods for cardiac assist technologies necessitates that they must be capable of reproducing the circulatory conditions that would exist physiologically. Of particular interest is the ability to determine instantaneous compliance of the system, and the ability to change the compliance in real-time. This capability enables continuous battery testing of conditions without stopping the flow to change the compliance chamber settings, and the simulation of dynamic changes in arterial compliance. The method tested involves the use of a compliance chamber utilizing a circular natural latex rubber membrane separating the fluid and air portions of the device. Change in system compliance is affected by the airspace pressure, which creates more reaction force at the membrane to the fluid pressure. A pressure sensor in the fluid portion of the chamber and a displacement sensor monitoring membrane center deflection allow for real-time inputs to the control algorithm. A predefined numerical model correlates the displacement sensor data to the volume displacement of the membrane. The control algorithm involves a tuned π loop maintaining the volume distention of the membrane via regulation of the air space pressure. The proportional integral (PI) controller tuning was achieved by creating a computational model of the compliance chamber using Simulink™ Simscape(®) toolboxes. These toolboxes were used to construct a model of the hydraulic, mechanical, and pneumatic elements in the physical design. Parameter Estimation™ tools and Design Optimization™ methods were employed to determine unknown physical parameters in the system, and tune the process controller used to maintain the compliance setting. It was found that the resulting control architecture was capable of maintaining compliance along a

    Mindikoglu, Ayse L.; Weir, Matthew R.

    2013-01-01

    Background Renal dysfunction is one of the most common complications of cirrhosis with high morbidity and mortality. Summary In subjects with cirrhosis, renal dysfunction can present either as a direct consequence of cirrhosis (e.g. hepatorenal syndrome Type I and Type II) or secondary to etiologies other than cirrhosis (chronic kidney disease due to diabetic nephropathy, prerenal azotemia). Or, patients with cirrhosis may have renal dysfunction resulting directly from cirrhosis; and an underlying chronic kidney disease. Key Messages Given the challenges in the differential diagnosis of renal dysfunction and insufficient accuracy of serum creatinine and creatinine-based glomerular filtration rate estimating equations in cirrhosis, there is an urgent need for more accurate biomarkers of renal dysfunction in this population. This review will discuss novel concepts for the diagnosis and classification of renal dysfunction in cirrhosis to overcome at least some of the diagnostic and therapeutic challenges. Additionally, a new classification will be proposed for renal dysfunction in cirrhosis. PMID:24107793

    Non-alcoholic steatohepatitis (NASH) is emerging as an important cause of cryptogenic cirrhosis. Obesity, diabetes mellitus and hyperlipidaemia are important risk factors for NASH. The presence of these risk factors in patients with cryptogenic cirrhosis may suggest NASH as an aetiology of cirrhosis in them. Twenty-five patients of cryptogenic cirrhosis were compared with 18 patients of hepatitis B virus and hepatitis C virus related cirrhosis and primary biliary cirrhosis for the presence of obesity, diabetes mellitus and hyperlipidaemia. Patients with cryptogenic cirrhosis were found to have a significantly higher body - mass index increased prevalence of diabetes mellitus and lower high-density lipoprotein compared to the controls. Increased body weight and diabetes mellitus may play a role in the causation of cirrhosis in patients with cryptogenic cirrhosis.

  1. [Frequency dependance of compliance].

    Science.gov (United States)

    Gayrard, P

    1975-01-01

    Resistance of peripheral or "small" airways is only a small part of the total pulmonary resistance (Raw). Even considerable obstruction in these airways will have little effect on total resistance. Conversely this will lead to inequality in the time constants of units in parallel, and dynamic lung compliance (C dyn) shall fall as respiratory frequence increases. C dyn is measured from simultaneous recordings of transpulmonary pressure (esophageal balloon) and volume obtained from a volume displacement plethysmograph. If Raw and static compliance are found to be normal, the frequency dependance of compliance will result from peripheral airway obstruction only. Early stages of chronic airway obstruction can be established by this method. However this appear not suitable for wide-scale studies.

    BACKGROUND/AIMS: In the circulation, insulin-like growth factor-I (IGF-I) is bound in a trimeric complex of 150 kDa with IGF binding protein-3 (IGFBP-3) and the acid-labile subunit (ALS). Whereas circulating IGF-I and IGFBP-3 are reported to be low in patients with chronic liver failure, the level...... of ALS has not been described in relation to hepatic dysfunction. The aim of the present study was therefore to measure circulating and hepatic venous concentrations of ALS in relation to hepatic function and the IGF axis. METHODS: Twenty-five patients with cirrhosis (Child class A/B/C:5/10/10) and 30...... controls with normal liver function were studied. During a haemodynamic investigation, blood samples were collected from the hepatic vein and femoral artery, and the plasma concentrations of ALS, IGF-I and IGFBP-3 were determined. RESULTS: Hepatic venous and arterial concentrations of ALS were...

    Modeling the propagation of blood pressure and flow along the fetoplacental arterial tree may improve interpretation of abnormal flow velocity waveforms in fetuses. The current models, however, either do not include a wide range of gestational ages or do not account for variation in anatomical, vascular, or rheological parameters. We developed a mathematical model of the pulsating fetoumbilical arterial circulation using Womersley's oscillatory flow theory and viscoelastic arterial wall properties. Arterial flow waves are calculated at different arterial locations from which the pulsatility index (PI) can be determined. We varied blood viscosity, placental and brain resistances, placental compliance, heart rate, stiffness of the arterial wall, and length of the umbilical arteries. The PI increases in the umbilical artery and decreases in the cerebral arteries, as a result of increasing placental resistance or decreasing brain resistance. Both changes in resistance decrease the flow through the placenta. An increased arterial stiffness increases the PIs in the entire fetoplacental circulation. Blood viscosity and peripheral bed compliance have limited influence on the flow profiles. Bradycardia and tachycardia increase and decrease the PI in all arteries, respectively. Umbilical arterial length has limited influence on the PI but affects the mean arterial pressure at the placental cord insertion. The model may improve the interpretation of arterial flow pulsations and thus may advance both the understanding of pathophysiological processes and clinical management.

    Objective To investigate elastic changes of the radial artery, a medium-sized muscular peripheral conduit artery, in patients with borderline systolic hypertension. Methods Using a non-invasive high-resolution echo-tracking device coupled to a photoplethysmography (Finapres system) allowing simultaneous arterial diameter and finger blood pressure monitoring, we measured radial artery elastic parameters of 20 patients with borderline systolic hypertension and 20 normal subjects according to Langewouters model.Results The diameter of the radial artery of control subjects and those with borderline systolic hypertension at the isobaric level of 100 mmHg and mean arterial pressure was similar, but the compliance and distensibility at similar conditions in patients with borderline systolic hypertension did not further reduced and even increased. Conclusion In patients with borderline systolic hypertension, the adaptive responses of the radial artery compliance and distensibility to increased pressure were directed to maintain its elasticity, contributing to the homeostasis of the cardiovascular system.

    Summary In nearly every multifactorial human disease, there are three periods that characterize our understanding and definition. First, there is a period in which there is rapid accumulation of descriptive data. Second, there is a longer and slower period as information is obtained that redefines and expands basic and clinical knowledge that lacks the final and important area of understanding aetiology and therapeutic intervention. Third, which is much less common for most diseases, is the vigorous definition of pathobiology and treatment. These phases are well illustrated by our current understanding of primary biliary cirrhosis (PBC). The term PBC was first used nearly 60 years ago and for the first 40 or so years, the primary research efforts were directed at clinical definitions and pathology. Subsequently, with the advent of molecular biology, there began a rigorous dissection of the immune response and, in particular, a better understanding of anti-mitochondrial antibodies. These efforts have greatly helped in our understanding of not only the effector mechanisms of disease, but also the uniqueness of the primary target tissue, biliary epithelium. However, this research has still not led to successful translation for specific therapy. PMID:18640737

    Full Text Available Genetic and environmental factors have been widely suggested to contribute to the pathogenesis of primary biliary cirrhosis (PBC, an autoimmune disease of unknown etiology leading to destruction of small bile ducts. Interestingly, epidemiologic data indicate a variable prevalence of the disease in different geographical areas. The study of clusters of PBC may provide clues as to possible triggers in the induction of immunopathology. We report herein four such unique PBC clusters that suggest the presence of both genetic and environmental factors in the induction of PBC. The first cluster is represented by a family of ten siblings of Palestinian origin that have an extraordinary frequency of PBC (with 5/8 sisters having the disease. Second, we describe the cases of a husband and wife, both having PBC. A family in which PBC was diagnosed in two genetically unrelated individuals, who lived in the same household, represents the third cluster. Fourth, we report a high prevalence of PBC cases in a very small area in Alaska. Although these data are anedoctal, the study of a large number of such clusters may provide a tool to estimate the roles of genetics and environment in the induction of autoimmunity.

    There has been a rapid growth in our understanding of the molecular bases of primary biliary cirrhosis (PBC). These efforts were initiated when the immunodominant mitochondrial autoantigen was cloned and sequenced. Using the recombinant cloned antigen as a tool, research has focused on the effector mechanisms of disease and the uniqueness of the primary target tissue, the intrahepatic bile ducts. Most recently, there have been experimental data suggesting that innate immunity changes may be critical to the initiation and perpetuation of the autoimmune injury, as in the case of the enhanced response of monocytes and memory B cells to infectious stimulation and environmental mimics. These observations are important as they help fill in the many gaps which remain on the most difficult subject of autoimmunity, etiology. Indeed, based on the available data, several experimental models of PBC have been developed. These models illustrate and suggest that PBC can be initiated by several mechanisms, all of which lead to loss of tolerance to the mitochondrial antigens. However, once this adaptive response develops, it appears that much of the subsequent pathology is exacerbated by innate responses. We suggest that future therapeutic efforts in PBC will depend heavily on understanding the nature of this innate immune responses and methodology to blunt their cytotoxicity.

    Full Text Available CONTEXT: Malnutrition in cirrhotic patients with end-stage disease is common, and the degree of nutritional debilitation can play an important role in the pathogenesis of complications and cause a negative impact on prognosis. However, it involves difficulties and controversies regarding the identification of the best nutritional assessment method. OBJECTIVE: To identify a method that provides a safe and effective nutritional diagnosis. METHODS: Cross-sectional study with 129 cirrhotic patients. Anthropometric measurements, subjective global assessment, hand grip strength and bioelectrical impedance. RESULTS: Through phase angle of bioelectrical impedance analysis (BIA method, significant associations with Child-Pugh (P = 0.008, age group and gender were observed. The ROC (receiver operator characteristic curve was generated to determine the best cutoff point of the phase angle of cirrhotic patients, serving as one of the reference parameters for the nutritional assessment with bioimpedance in this study, considering the classification through Child-Pugh score as the reference standard for the clinical conditions of patients with cirrhosis. CONCLUSIONS: The assessment through bioelectrical impedance presented a statistically significant correlation with Child-Pugh score. The identification of phase angle of 5.44º is the new parameter suggested for the classification of the nutritional conditions of cirrhotic patients.

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

    AIM: To analyze β2-integrin expression on blood leukocytes in liver cirrhosis.METHODS: In 40 patients with liver cirrhosis and 20healthy individuals, the evaluation of expression of CD11a (LFA-1α), CD11b (Mac-1α), CD11c (αX) and CD49d (VLA-4α) on peripheral blood leukocytes was performed using flow cytometry. The analysis was carried out in groups of patients divided into B and C according to Child-Pugh's classification.RESULTS: An increased CD11a, CD11b, CD11c and CD49d integrin expression was observed on peripheral blood leukocytes in liver cirrhosis. The integrin levels were elevated as the advancement of liver failure progressed. The highest expression of integrins occurred predominantly on monocytes. A slight expression of VLA-4 was found on lymphocytes and granulocytes and it increased together with liver failure. A positive correlation was noted between median intensity of fluorescence (MIF) expression on polymorphonuclear cells of CD11a and CD11c and CD49d (r = 0.42, P < 0.01; r = 053, P < 0.01, respectively) in liver cirrhosis stage C. However,no correlation was observed between integrin expression on leukocytes. The concentrations of sICAM-1, sVCAM-1,and TNFα, were significantly elevated in liver cirrhosis.CONCLUSION: β2-integrin expression on leukocytes increases in liver cirrhosis decompensated as the stage of liver failure increases, which is a result of permanent activation of leukocytes circulating through the inflamed liver environment. β2-integrin expression on circulating leukocytes can intensify liver cirrhosis.

    The gut microbiota has the capacity to produce a diverse range of compounds that play a major role in regulating the activity of distal organs and the liver is strategically positioned downstream of the gut. Gut microbiota linked compounds such as short chain fatty acids, bile acids, choline metabolites, indole derivatives, vitamins, polyamines, lipids, neurotransmitters and neuroactive compounds, and hypothalamic-pituitary-adrenal axis hormones have many biological functions. This review focuses on the gut microbiota and host metabolism in liver cirrhosis. Dysbiosis in liver cirrhosis causes serious complications, such as bacteremia and hepatic encephalopathy, accompanied by small intestinal bacterial overgrowth and increased intestinal permeability. Gut dysbiosis in cirrhosis and intervention with probiotics and synbiotics in a clinical setting is reviewed and evaluated. Recent studies have revealed the relationship between gut microbiota and host metabolism in chronic metabolic liver disease, especially, non-alcoholic fatty liver disease, alcoholic liver disease, and with the gut microbiota metabolic interactions in dysbiosis related metabolic diseases such as diabetes and obesity. Recently, our understanding of the relationship between the gut and liver and how this regulates systemic metabolic changes in liver cirrhosis has increased. The serum lipid levels of phospholipids, free fatty acids, polyunsaturated fatty acids, especially, eicosapentaenoic acid, arachidonic acid, and docosahexaenoic acid have significant correlations with specific fecal flora in liver cirrhosis. Many clinical and experimental reports support the relationship between fatty acid metabolism and gut-microbiota. Various blood metabolome such as cytokines, amino acids, and vitamins are correlated with gut microbiota in probiotics-treated liver cirrhosis patients. The future evaluation of the gut-microbiota-liver metabolic network and the intervention of these relationships using probiotics

    Healthcare organizations have created corporate compliance programs in an effort to adhere to Federal government recommendations, minimize the risk of wrongful behavior, and possibly reduce fines that may result from a government investigation. Compliance programs may have undetected weaknesses. Corporate compliance officers, executives, and board members need to be certain that their organization's program has sufficient infrastructure, oversight, and resources; effective education and training; an effective mechanism (hotline) to receive reports of compliance problems; and ongoing auditing and monitoring capabilities.

    Until recently, anti-platelet/coagulation therapy hadnot been recommended for patients with cirrhosis.Although venous thrombosis is one of the representativecomplications of cirrhosis and ischemic disordersassociated with atherosclerosis are not infrequent incirrhotic patients, many clinicians have tended to hesitateto introduce anti-platelet/coagulation therapy to theirpatients. Undoubtedly, this is due to the increased riskof hemorrhagic diathesis in cirrhotic patients. However,accumulating evidence has revealed the benefits ofanti-platelet/coagulation therapy for cirrhotic patients.In addition to the safety of the therapy carried outagainst cardiovascular diseases in cirrhotic patients,some clinical data have indicated its preventive effecton venous thrombosis. Moreover, the efficacy of antiplatelet/coagulation therapy against cirrhosis itself hasbeen demonstrated both clinically and experimentally.The conceptual basis for application of anti-platelet/coagulation therapy against cirrhosis was constructedthrough two pathologic studies on intrahepatic thrombosisin cirrhotic livers. It may be better to use thrombopoietinreceptoragonists, which have been tested as a treatmentfor cirrhosis-related thrombocytopenia, in combinationwith anti-platelet drugs to reduce the risk of venousthrombosis. During the last decade, the World Journalof Gastroenterology , a sister journal of World Journal ofHepatology , has been one of the main platforms of activediscussion of this theme.

    Full Text Available The status of 121 patients who were found to have liver cirrhosis on liver biopsy in 1981 was assessed seven years later. The etiology of the cirrhosis was alcoholic in 52%, cryptogenic in 29.8%, hepatitis B-related in 9.1% and miscellaneous in 9.1%. In 1981, jaundice was present in 55 patients (45.8%, ascites in 52 (43%, gastrointestinal bleeding in 25 (20.7% and encephalopathy in 10 (8.3%. During the following seven years an additional 20 patients developed ascites, 15 gastrointestinal bleeding, 32 encephalopathy and three hepatocellular carcinoma. The mortality race was 43.8% at five years and 53.7% at seven years. The principal cause of death was liver failure (40%, followed by nonliver causes (32.3% and gastrointestinal bleeding (13.9%. One patient died of hepatocellular carcinoma. Patients who survived seven years had fewer complications when seen in 1981 than those who died during this period (P<0.025. It is concluded that, in Toronto, cirrhosis is often caused by ethanol abuse and hepatitis B infection; that it is associated with significant morbidity and mortality; and that the number of complications when the patient is first seen may be a useful indicator of prognosis. Since many cases of cirrhosis are preventable, the authors suggest that efforts directed towards prevention of cirrhosis may be more rewarding than those directed towards therapy.

    Full Text Available The use of carbon tetrachloride (CCl4 in rats is an experimental model of hepatic tissue damage; which leads to fibrosis, and at the long term, cirrhosis. Cirrhosis is the consequence of progressive continued liver damage, it may be reversible when the damaging noxae have been withdrawn. The aim of this study is to evaluate the changes caused by cirrhosis in lung and liver, through the experimental model of intraperitoneal CCI4 administration. We used 18 male Wistar rats divided into three groups: control (CO and two groups divided by the time of cirrhosis induction by CCI4: G1 (11 weeks, G2 (16 weeks. We found significant increase of transaminase levels and lipid peroxidation (TBARS in liver and lung tissue and also increased antioxidant enzymes SOD and CAT, as well as the expression of TNF-α and IL-1β in the lung of cirrhotic animals. We observed changes in gas exchange in both cirrhotic groups. We can conclude that our model reproduces a model of liver cirrhosis, which causes alterations in the pulmonary system that leads to changes in gas exchange and size of pulmonary vessels.

    Full Text Available Context Liver cirrhosis patients with hepatocellular carcinoma present nutritional alterations and metabolic disorders that negatively impact the prognosis. Objective The objective is to identify alterations in the metabolism of macro and micronutrients among liver cirrhosis patients with and without hepatocellular carcinoma and their relation to the Child-Turcote-Pugh score and Barcelona Clinic Liver Cancer staging. Methods Analytical transversal study, with 31 hepatocellular carcinoma patients and 48 liver cirrhosis patients. Laboratorial exams were carried out. The existence of an association between the biochemical parameters and the disease severity as well as the presence of hepatocellular carcinoma was assessed. Results The metabolic-nutritional profile of liver cirrhosis patients caused by the hepatitis C virus and hepatocellular carcinoma showed alterations, specifically the lipid (total cholesterol, HDL and triglycerides, protein (albumin, creatinine and uric acid, iron (transferrin, iron and ferritin saturation, hematocrit and hemoglobin, zinc and B12 vitamin profiles. There is a relation between nutritional biochemical markers and the Child-Turcote-Pugh, as well as Barcelona Clinic Liver Cancer staging. Conclusions Considering the existence of alterations in the metabolism of nutrients in liver cirrhosis patients with and without hepatocellular carcinoma, and also that conventional nutritional assessment methods present limitations for this population, the biochemical laboratorial exams are valid to complement the diagnosis of the nutritional state in a quick and practical manner.

  4. Cryptogenetic liver cirrhosis and prothrombotic mutations: a mere association?

    Directory of Open Access Journals (Sweden)

    María Monereo-Muñoz

    Full Text Available Thrombin activation and microthrombosis of intrahepatic portal venules is a common feature in liver cirrhosis, due in part to relative protein C deficiency and altered coagulation-anticoagulation-fibrinolysis balance. Extension of this microthrombotic process to larger portal vessels explains the increased incidence of portal vein thrombosis in liver cirrhosis. Thrombin not only leads to thrombosis, but also activates liver stellate cells and promotes fibrogenesis. Also, ischemia associated with thrombosis up-regulates the expression and secretion of growth factors involved in fibrogenesis. The coincidence in a given patient of prothrombotic mutations, such as factor V Leiden or PAI-1 polymorphisms, can accelerate the fibrogenetic process. We hereby present two cases of liver cirrhosis in which etiologic evaluation was negative except for the finding of a factor V Leiden mutation in one case and the 4G/5G PAI polymorphism in the second case. These observations support the hypothesis that these mutations may be involved in the etiology of some cases of cirrhosis, or, at least, accelerate the evolution of the disease. It is therefore convenient to search for the presence of prothrombotic mutations in patients with cryptogenetic cirrhosis.

    Full Text Available Patients with decompensated liver cirrhosis have significantly impaired synthetic function. Many proteins involved in the coagulation process are synthesized in the liver. Routinely performed tests of the coagulation are abnormal in patients with decompensated liver cirrhosis. This has led to the widespread belief that decompensated liver cirrhosis is prototype of acquired hemorrhagic coagulopathy. If prothrombin time is prolonged more than 3 seconds over control, invasive procedures like liver biopsy, splenoportogram, percutaneous cholangiography, or surgery were associated with increased risk of bleeding, and coagulopathy should be corrected with infusion of fresh frozen plasma. These practices were without any scientific evidence and were associated with significant hazards of fresh frozen plasma transfusion. Now, it is realized that coagulation is a complex process involving the interaction of procoagulation and anticoagulation factors and the fibrinolytic system. As there is reduction in both anti and procoagulant factors, global tests of coagulation are normal in patients with acute and chronic liver disease indicating that coagulopathy in liver disease is more of a myth than a reality. In the last few years, surgical techniques have substantially improved, and complex procedures like liver transplantation can be done without the use of blood or blood products. Patients with liver cirrhosis may also be at increased risk of thrombosis. In this paper, we will discuss coagulopathy, increased risk of thrombosis, and their management in decompensated liver cirrhosis.

    2011-01-01

    This article discusses a practical, evidence-based approach to the diagnosis and management of liver cirrhosis by focusing on etiology, severity, presence of complications, and potential home-managed treatments. Relevant literature from 1985 to 2010 (PubMed) was reviewed. The search criteria were peer-reviewed full papers published in English using the following MESH headings alone or in combination: "ascites", "liver fibrosis","cirrhosis", "chronic hepatitis", "chronic liver disease","decompensated cirrhosis", "hepatic encephalopathy","hypertransaminasemia", "liver transplantation" and "portal hypertension". Forty-nine papers were selected based on the highest quality of evidence for each section and type (original, randomized controlled trial, guideline, and review article), with respect to specialist setting (Gastroenterology,Hepatology, and Internal Medicine) and primary care. Liver cirrhosis from any cause represents an emerging health issue due to the increasing prevalence of the disease and its complications worldwide. Primary care physicians play a key role in early identification of risk factors, in the management of patients for improving quality and length of life, and for preventing complications.Specialists, by contrast, should guide specific treatments, especially in the case of complications and for selecting patient candidates for liver transplantation. An integrated approach between specialists and primary care physicians is essential for providing better outcomes and appropriate home care for patients with liver cirrhosis.

    2012-01-01

    BACKGROUND: Splenic artery aneurysms although rare are clinically signiifcant in view of their propensity for spontaneous rupture and life-threatening bleeding. While portal hypertension is an important etiological factor, the majority of reported cases are secondary to cirrhosis of the liver. We report three cases of splenic artery aneurysms associated with extrahepatic portal vein obstruction and discuss their management. METHODS: The records of three patients of splenic artery aneurysm associated with extrahepatic portal vein obstruction managed from 2003 to 2010 were reviewed retrospectively. The clinical presentation, surgical treatment and outcome were analyzed. RESULTS:  The aneurysm was >3 cm in all patients. The clinical symptoms were secondary to extrahepatic portal vein obstruction (hematemesis in two, portal biliopathy in two) while the aneurysm was asymptomatic. Doppler ultrasound demonstrated aneurysms in all patients. A proximal splenorenal shunt was performed in two patients with excision of the aneurysm in one patient and ligation of the aneurysm in another one. The third patient had the splenic vein replaced by collaterals and hence underwent splenectomy with aneurysmectomy. All patients had an uneventful post-operative course. CONCLUSIONS: Splenic artery aneurysms are associated with extrahepatic portal vein obstruction. Surgery is the mainstay of treatment. Although technically dififcult, it can be safely performed in an experienced center with minimal morbidity and good outcome.

    1976-01-01

    The 20 minutes' liver/heart activity ratio after rectal administration of 13N-ammonia was abnormally low (less than 2.25) in 12 of 26 patients with cirrhosis of the liver. An abnormal conventional rectal arterial ammonia test (porta-systemic shunts), an abnormally low urea index (prevailing hepatofugal portal venous flow direction), marked portal hypertension (hepatic sinusoidal pressure greater than or equal to 8 mm Hg), ascites and extreme enlargement of the spleen occurred significantly more often in the patients with an abnormally low 13N-liver/heart ratio than in those with a ratio greater than or equal to 2.25. There was no correlation between the 13N-liver/heart ratio and absence or presence of oesophageal varices. The non-invasive rectal 13N-ammonia test appears to be an easy to perform, informative test in cirrhosis of the liver.

    Full Text Available Cryptogenic cirrhosis (CC is defined as cirrhosis occurring in an individual without an identifiable cause of liver disease, such as excessive alcohol consumption, viral hepatitis infection, hemochromatosis, autoimmune hepatitis, primary biliary cirrhosis, primary sclerosing cholangitis, chronic intake of medications that could induce cirrhosis, alpha-1-antitrypsin deficiency, Wilson’s disease, or any other rare cause of cirrhosis according to the clinical context. Cryptogenic cirrhosis is a common cause of liver-related morbidity and mortality in the United States. Nonalcoholic fatty liver disease is now recognized as the most common cause of cryptogenic cirrhosis. A biopsy specimen is also important for detecting histological advanced disease, which may be clinically silent and undetected by liver-related tests or diagnostic imaging. We are presenting an unusual case of a patient with cryptogenic cirrhosis found to have Kayser-Fleischer-like rings without evidence of Wilson’s disease.

    AIM: To analyze hepatic, mesenteric and mucosal microcirculation and leukocyte-endothelium interaction (LEI) in a rat model with liver cirrhosis.METHODS: Hepatic cirrhosis was induced in Wistar rats by gavage with carbon tetrachloride, and intravital videomicroscopy was performed in liver, mesentery and small intestine mucosa. Special emphasis is given on microcirculatory and morphometric changes during cirrhotic portal hypertension.RESULTS: LEI was influenced significantly in the cirrhotic liver but not in the gut. Blood flow measurement showed significant differences among liver, main mesenteric vessels and the mucosa. The results of our study indicate that liver cirrhosis leads to alterations in hepatic and mesenteric blood flow but not in mucosal blood flow.CONCLUSION: The enhanced inflammatory response in hepatic microvessels may be caused by a decrease of antithrombin Ⅲ levels and could be responsible for disturbances of organ pathology.

    Liver cirrhosis is the end stage of many different chronic liver diseases and is becoming an important cause of mortality and morbidity across the world. In theory, the numerous physiopathological changes suffered by these patients warrant relevant pharmacokinetic changes in most drugs. However, the influence of these changes on the efficacy and toxicity responses of patients with cirrhosis have been evaluated by few clinical trials and observational studies. As a consequence, therapeutic decisions in these patients are usually complex and subject to uncertainties. In this article, we review the regulatory guidelines to study responses to drugs according to pharmacokinetic variability and the published information that is useful for guiding the dosage adjustment of frequently used drugs in patients with cirrhosis (antivirals, antibiotics, analgesics, etc.) to obtain the best risk-benefit ratio.

    The global distribution of hepatocellular carcinoma(HCC) varies markedly among regions, and patients in East Asia and Central Africa account for about 80% of all cases. The risk factors are hepatitis B, hepatitis C, alcohol, and etc. The risk of carcinogenesis further increases with progression to hepatic cirrhosis in all liver disorders. Radical treatment of HCC by liver resection without causing liver failure has been established as a safe approach through selection of an appropriate range of resection of the damaged liver. This background indicates that both evaluation of hepatic functional reserve and measures against concomitant diseases such as thrombocytopenia accompanying portal hypertension, prevention of rupture of esophageal varices, reliable control of ascites, and improvement of hypoalbuminemia are important issues in liver resection in patients with hepatic cirrhosis. We review the latest information on perioperative management of liver resection in HCC patients with hepatic cirrhosis.

    Full Text Available We investigate the notion of orchestrated compliance for client/server interactions in the context of session contracts. Devising the notion of orchestrator in such a context makes it possible to have orchestrators with unbounded buffering capabilities and at the same time to guarantee any message from the client to be eventually delivered by the orchestrator to the server, while preventing the server from sending messages which are kept indefinitely inside the orchestrator. The compliance relation is shown to be decidable by means of 1 a procedure synthesising the orchestrators, if any, making a client compliant with a server, and 2 a procedure for deciding whether an orchestrator behaves in a proper way as mentioned before.

    Ensuring compliance of organizations to federal regulations is a growing concern. This paper presents a framework and methods to verify whether an implemented low-level security policy is compliant to a high-level security policy. Our compliance checking framework is based on organizational and security metadata to support refinement of high-level concepts to implementation specific instances. Our work uses the results of refinement calculus to express valid refinement patterns and their properties. Intuitively, a low-level security policy is compliant to a high-level security policy if there is a valid refinement path from the high-level security policy to the low-level security policy. Our model is capable of detecting violations of security policies, failures to meet obligations, and capability and modal conflicts.

  2. Agent Architectures for Compliance

    Science.gov (United States)

    Burgemeestre, Brigitte; Hulstijn, Joris; Tan, Yao-Hua

    A Normative Multi-Agent System consists of autonomous agents who must comply with social norms. Different kinds of norms make different assumptions about the cognitive architecture of the agents. For example, a principle-based norm assumes that agents can reflect upon the consequences of their actions; a rule-based formulation only assumes that agents can avoid violations. In this paper we present several cognitive agent architectures for self-monitoring and compliance. We show how different assumptions about the cognitive architecture lead to different information needs when assessing compliance. The approach is validated with a case study of horizontal monitoring, an approach to corporate tax auditing recently introduced by the Dutch Customs and Tax Authority.

    AIM: In patients with liver cirrhosis and porlal hypertension, portal hypertensive colopathy is thought to be an important cause of lower gastrointestinal hemorrhage. In this study, we evaluated the prevalence of colonic mucosal changes in patients with liver cirrhosis and its clinical significance. METHODS: We evaluated the colonoscopic findings and liver function of 47 patients with liver cirrhosis over a 6-year period. The main cause of liver cirrhosis was post-viral hepatitis (68%) related to hepatitis B (6%) or C (62%)infection. All patients underwent upper gastrointestinal endoscopy to examine the presence of esophageal varices, cardiac varices, and congestive gastropathy, as well as a full colonoscopy to observe changes in colonic mucosa. Portal hypertensive colopathy was defined endoscopically in patients with vascular ectasia, redness, and blue vein. Vascular ectasia was classified into two types: type 1, solitary vascular ectasia; and type 2, diffuse vascular ectasia.RESULTS: Overall portal hypertensive colopathy was present in 31 patients (66%), including solitary vascular ectasia in 17 patients (36%), diffuse vascular ectasia in 20 patients (42%), redness in 10 patients (21%) and blue vein in 6 patients (12%). As the Child-Pugh class increased in severity, the prevalence of portal hypertensive colopathy rose. Child-Pugh class B and C were significantly associated with portal hypertensive colopathy. Portal hypertensive gastropathy, esophageal varices, ascites and hepatocellular carcinoma were not related to occurrence of portal hypertensive colopathy. Platelet count was significantly associated with portal hypertensive colopathy, but prothrombin time, serum albumin level, total bilirubin level and serum ALT level were not related to occurrence of portal hypertensive colopathy. CONCLUSION: As the Child-Pugh class worsens and platelet count decreases, the prevalence of portal hypertensive colopathy increases in patients with liver cirrhosis. A colonoscopic

    Between 1944 and 1947 the mortality statistics for the Danish population show an epidemic increase of liver diseases: subacute necrosis and cirrhosis. The epidemic only affected female mortality rates.

    Full Text Available Escherichia coli (E. coli is a rare cause of ocular infections and has not yet been reported as a cause of an ocular abscess. We describe the case of a 47-year-old woman with a history of alcoholic cirrhosis who presented with painful left lower eyelid swelling that did not improve with oral antibiotics. The abscess was drained and cultures were positive for E. coli. Patients with cirrhosis are at increased risk for developing E. coli bacterial infections, but to our knowledge this is the first case of an E. coli eyelid abscess reported in the literature.

    Primary biliary cirrhosis is an uncommon disease amongst Malaysians. Over a 12-year period, between 1979 and 1991, only seven patients with clinical, biochemical and histologic evidence of primary biliary cirrhosis were identified in University Hospital Kuala Lumpur. All were Chinese females between the ages of 30 to 55 years. The presenting complaint was pruritus in 5 patients. All except one patient was jaundiced when the diagnosis was made. These patients were followed up from 1 to 11 years. Three deaths were reported, one from massive hemetemesis and two from liver failure.

    Nonalcoholic fatty liver disease (NAFLD) is the hepatic manifestation of the metabolic syndrome and comprises a liver disease spectrum ranging from steatosis to nonalcoholic steatohepatitis (NASH) with risk of progression to liver cirrhosis and hepatocellular carcinoma (HCC). Associated metabolic conditions and comorbidities such as obesity, diabetes and cardiovascular diseases are common and require concerted management. Adiponutrin (PNPLA3) variants may help to identify NAFLD patients at higher risk for liver disease progression towards advanced fibrosis and HCC. The therapeutic options in NAFLD/NASH include lifestyle modification, pharmacological treatment, bariatric surgery for patients with morbid obesity and treatment of complications of liver cirrhosis and HCC, including liver transplantation. Insulin sensitizers and antioxidative treatment strategies with vitamin E are among the best-established pharmacological approaches, but both drugs have long-term safety issues and there is limited evidence in cirrhotic patients. Treatment of concomitant/underlying metabolic conditions with statins or metformin may also have beneficial effects on portal hypertension, complications of liver cirrhosis and HCC prevention. The bile acid receptor FXR may be a promising novel therapeutic target for the treatment of NAFLD/NASH, fibrosis and portal hypertension, but the prognostic implications of associated changes in low- and high-density lipoprotein cholesterol require further studies. Morbidly obese NASH patients can benefit from bariatric surgery which may reduce liver fibrosis but carries a risk of decompensation in patients with advanced liver cirrhosis. When carefully selected, patients with NASH cirrhosis undergoing liver transplantation have a good outcome. This review summarizes recent progress in the management of patients with liver cirrhosis due to NASH.

    This paper models the impact of extrinsic incentives in a tax compliance model. It also provides experimental evidence that confirms the existence of a positive relationship between rewards and tax compliance. If individuals are audited, rewards for honest taxpayers are effective in increasing the level of tax compliance. These results are particularly relevant in countries where there is little respect for tax law since rewards can contribute to crowding in the intrinsic motivation to comply.

    2006-01-01

    Primary biliary cirrhosis (PBC) is a disease of unknown etiology leading to progressive destruction of small intrahepatic bile ducts and eventually to liver cirrhosis and failure. It is characterised by female predominance and serum auto-antibodies to mitochondrial antigens targeting the E2 components of the 2-oxoacid dehydrogenase complex. Although they are associated with disease pathogenesis, no concrete evidence has been presented so far. Epidemiological data indicate that a geographical clustering of cases and possible environmental factors are implicated in pathogenesis. A number of genetic factors play a role in determining disease susceptibility or progression, although no definitive conclusion has been reached so far. A key factor to immune pathogenesis is considered to be the breakdown of immune tolerance, either through molecular mimicry or through the so called determinant density model. Tn this review, the available data regarding the pathogenesis of primary biliary cirrhosis are described and discussed. A new unifying hypothesis based on early endothelin overproduction in primary biliary cirrhosis (PBC) is presented and discussed.

    Recurrence of the original disease following liver transplantation is not uncommon and can lead to graft failure. There are limited data on recurrent fatty liver disease following liver transplantation. The aim of this study was to determine the incidence of recurrent fatty liver disease in patients with biopsy-proven nonalcoholic steatohepatitis, its effect on survival, and whether there are any predictive factors for recurrence. We analyzed patients undergoing liver transplantation for nonalcoholic steatohepatitis cirrhosis from 1997 to 2008 at a single center. Patients undergoing transplantation for cholestatic disease, alcohol, hepatitis C, or cryptogenic cirrhosis were controls. Ninety-eight patients underwent transplantation for nonalcoholic steatohepatitis cirrhosis. Recurrent fatty liver disease was seen in 70%, 25% had recurrent nonalcoholic steatohepatitis, and 18% had stage II/IV or greater fibrosis at a mean of 18 months. No patients with recurrent nonalcoholic steatohepatitis developed graft failure or required retransplantation at a follow-up of 3 years. No recipient or donor factors were associated with disease recurrence, although patients with recurrent nonalcoholic steatohepatitis had a higher incidence of diabetes, weight gain, and dyslipidemia at the time of diagnosis of recurrence. One-third of patients with recurrent nonalcoholic steatohepatitis had normal liver enzymes at the time of diagnosis post-transplantation. In conclusion, recurrent fatty liver disease is common following liver transplantation for nonalcoholic steatohepatitis cirrhosis but does not lead to early allograft failure. Recurrent nonalcoholic steatohepatitis can occur despite normal liver enzymes, and features of metabolic syndrome are associated with disease recurrence.

    Full Text Available Background Renal failure is a frequent and serious complication in patients with decompensated cirrhosis. Objectives We aimed to evaluate the renal oxidative stress, cell damage and impaired cell function in animal model of cirrhosis. Methods Secondary biliary cirrhosis was induced in rats by ligation of the common bile duct. We measured TBARS, ROS and mitochondrial membrane potential in kidney as markers of oxidative stress, and activities of the antioxidant enzymes. Relative cell viability was determined by trypan blue dye-exclusion assay. Annexin V-PE was used with a vital dye, 7-AAD, to distinguish apoptotic from necrotic cells and comet assay was used for determined DNA integrity in single cells. Results In bile duct ligation animals there was significant increase in the kidney lipoperoxidation and an increase of the level of intracellular ROS. There was too an increase in the activity of all antioxidant enzymes evaluated in the kidney. The percentage viability was above 90% in the control group and in bile duct ligation was 64.66% and the dominant cell death type was apoptosis. DNA damage was observed in the bile duct ligation. There was a decreased in the mitochondrial membrane potential from 71.40% ± 6.35% to 34.48% ± 11.40% in bile duct ligation. Conclusions These results indicate that intracellular increase of ROS cause damage in the DNA and apoptosis getting worse the renal function in cirrhosis.

    Full Text Available Introduction: Indian childhood cirrhosis is a chronic liver disease usually seen in paediatric age group and is unique to the Indian subcontinent. The definitive causative factor for the disease is not found till now but excess copper ingestion has been associated with it.Case presentation: An Indian origin one and half year old premorbidly normal male child presented with history of gradual distension of abdomen for 6 months and jaundice, generalized body swelling, high colour urine for 20 days. There was no history of any bleeding or feature suggestive of hepatic encephalopathy. On physical examination child was icteric, pale and had anasarca, massive hepatosplenomegaly and ascites. The child was evaluated for various causes of hepatic failure in pediatric age group including infective, metabolic and autoimmune etiologies. Unfortunately the child succumbed to the illness. The post-mortem liver biopsy and copper estimation cleared the air, revealing Indian childhood cirrhosis as the underlying etiology.Conclusion: Though Indian childhood cirrhosis is a rare entity and reported less frequently in literature, the treating pediatrician should keep this as a differential in case of pediatric hepatic failure. The liver biopsy and hepatic copper estimation are the gold standard diagnostic tests for diagnosing Indian Childhood cirrhosis.

    Proton Pump Inhibitors (PPI) are very effective in inhibiting acid secretion and are extensively used in many acid related diseases. They are also often used in patients with cirrhosis sometimes in the absence of a specific acid related disease, with the aim of preventing peptic complications in patients with variceal or hypertensive gastropathic bleeding receiving multidrug treatment. Contradicting reports support their use in cirrhosis and evidence of their efficacy in this condition is poor. Moreover there are convincing papers suggesting that acid secretion is reduced in patients with liver cirrhosis. With regard to H pylori infection, its prevalence in patients with cirrhosis is largely variable among different studies, and it seems that H pylori eradication does not prevent gastro-duodenal ulcer formation and bleeding. With regard to the prevention and treatment of oesophageal complications after banding or sclerotherapy of oesophageal varices, there is little evidence for a protective role of PPI. Moreover, due to liver metabolism of PPI, the dose of most available PPIs should be reduced in cirrhotics. In conclusion, the use of this class of drugs seems more habit related than evidence-based eventually leading to an increase in health costs.

    Patients who are infected with hepatitis C virus (HCV)and also have advanced fibrosis or cirrhosis have beenrecognized as "difficult-to-treat" patients during an erawhen peginterferon and ribavirin combination therapy isthe standard of care. Recent guidelines have clearly statedthat treatment should be prioritized in this populationto prevent complications such as decompensationand hepatocellular carcinoma. Recent advances in thetreatment of chronic hepatitis C have been achievedthrough the development of direct-acting antiviral agents(DAAs). Boceprevir and telaprevir are first-generationDAAs that inhibit the HCV NS3/4A protease. Bocepreviror telaprevir, in combination with peginterferon andribavirin, improved the sustained virological responserates compared with peginterferon and ribavirin alone andwere tolerated in patients with HCV genotype 1 infectionwithout cirrhosis or compensated cirrhosis. However, theefficacy is lower especially in prior non-responders withor without cirrhosis. Furthermore, a high incidence ofadverse events was observed in patients with advancedliver disease, including cirrhosis, in real-life settings.Current guidelines in the United States and in someEuropean countries no longer recommend these regimensfor the treatment of HCV. Next-generation DAAs includesecond-generation HCV NS3/4A protease inhibitors, HCVNS5A inhibitors and HCV NS5B inhibitors, which have ahigh efficacy and a lower toxicity. These drugs are usedin interferon-free or in interferon-based regimens withor without ribavirin in combination with different classesof DAAs. Interferon-based regimens, such as simeprevirin combination with peginterferon and ribavirin, are welltolerated and are highly effective especially in treatmentna?vepatients and in patients who received treatmentbut who relapsed. The efficacy is less pronounced in nullrespondersand in patients with cirrhosis. Interferonfreeregimens in combination with ribavirin and/ortwo or more DAAs could be

    AIM: To determine the correlation between portal hemodynamics and spleen function among different grades of cirrhosis and verify its significance in cirrhosis staging.METHODS: The portal and splenic vein hemodynamics and spleen size were investigated by ultrasonography in consecutive 38 cirrhotic patients with cirrhosis (Child's grades A to C) and 20 normal controls. The differences were compared in portal vein diameter and flow velocity between patients with and without ascites and between patients with mild and severe esophageal varices. The correlation between peripheral blood cell counts and Child's grades was also determined.RESULTS: The portal flow velocity and volume were significantly lower in patients with Child's C (12.25±1.67 cm/s vs 788.59±234 mm/min, respectively) cirrhosis compared to controls (19.55±3.28 cm/s vs 1254.03±410 mm/min,respectively) and those with Child's A (18.5±3.02 cm/s vs1358.48±384 mm/min, respectively) and Child's B (16.0±3.89cm/s vs 1142.23±390 mm/min, respectively)cirrhosis.Patients with ascites had much lower portal flow velocity and volume (13.0±1.72 cm/s vs 1078±533 mm/min) than those without ascites (18.6±2.60 cm/s vs 1394±354 mm/min).There was no statistical difference between patients with mild and severe esophageal varices. The portal vein diameter was not significantly different among the above groups.There were significant differences in splenic vein diameter,flow velocity and white blood cell count, but not in spleen size, red blood cell and platelet counts among the various grades of cirrhosis. The spleen size was negatively correlated with red blood cell and platelet counts (r= -0.620and r = -0.8.34, respectively).CONCLUSION: An optimal system that includes parameters representing the portal hemodynamics and spleen function should be proposed for cirrhosis staging.

    AIM: To search for transcription dysregulation that could (1) differentiate hepatocellular carcinoma (HCC)-free from HCC-related cirrhosis (2) differentiate HCCfree cirrhosis related to HCV from that related to alcohol intake.METHODS: Using microarray analysis, we compared transcript levels in HCC-free cirrhosis (alcoholism: 7;hepatitis C: 7), HCC-associated cirrhosis (alcoholism:10; hepatitis C: 10) and eight control livers. The identified transcripts were validated by qRT-PCR in an independent cohort of 45 samples (20 HCCfree cirrhosis; 15 HCC-associated cirrhosis and 10 control livers). We also confirmed our results by immunohistochemistry.transcripts which differentiated between alcoholicrelated cirrhosis, HCV-related cirrhosis and control livers. They mainly corresponded to down-regulation.Dysregulation of Signal Transduction and Activator of Transcription-3 (STAT-3) was found along with related changes in STAT-3 targets which occurred in an etiology-dependent fashion in HCC-free cirrhosis.In contrast, in HCC, such transcription dysregulations were not observed.CONCLUSION: We report that transcriptional dysregulations exist in HCC-free cirrhosis, are transiently observed prior to detectable HCC onset and may be appear like markers from cirrhosis to HCC transition.

    AIM: To summarize the characteristics of patients suffered from primary biliary cirrhosis associated with ulcerative colitis.METHODS: To report a new case and review the literature.RESULTS: There were 18 cases (including our case) of primary biliary cirrhosis complicated with ulcerative colitis reported in the literature. Compared with classical primary biliary cirrhosis, the patients were more often males and younger similar. The bowel lesions were usually mild with proctitis predominated. While ulcerative colitis was diagnosed before primary biliary cirrhosis in 13 cases, the presentation of primary biliary cirrhosis was earlier than that of ulcerative colitis in our new case reported here. The prevalence of primary biliary cirrhosis among patients of ulcerative colitis was almost 30 times higher than in general population.CONCLUSION: Association of primary biliary cirrhosis with ulcerative colitis is rare. It should be considered in the differential diagnosis of hepatobiliary disease in patients with ulcerative colitis, and vice versa.

    The Klotho gene is a suppressor of the aging phenomena, and the secretion as well as the circulation of Klotho proteins decrease with aging. Although habitual exercise has antiaging effects (e.g., a decrease in arterial stiffness), the relationship between Klotho and habitual exercise remains unclear. In the present study, we investigated the effect of habitual exercise on Klotho, with a particular focus on arterial stiffness. First, we examined the correlation between plasma Klotho concentration and arterial stiffness (carotid artery compliance and β-stiffness index) or aerobic exercise capacity [oxygen uptake at ventilatory threshold (VT)] in 69 healthy, postmenopausal women (50-76 years old) by conducting a cross-sectional study. Second, we tested the effects of aerobic exercise training on plasma Klotho concentrations and arterial stiffness. A total of 19 healthy, postmenopausal women (50-76 years old) were divided into two groups: control group and exercise group. The exercise group completed 12 wk of moderate aerobic exercise training. In the cross-sectional study, plasma Klotho concentrations positively correlated with carotid artery compliance and VT and negatively correlated with the β-stiffness index. In the interventional study, aerobic exercise training increased plasma Klotho concentrations and carotid artery compliance and decreased the β-stiffness index. Moreover, the changes in plasma Klotho concentration and arterial stiffness were found to be correlated. These results suggest a possible role for secreted Klotho in the exercise-induced modulation of arterial stiffness.

    Liver cirrhosis is a major cause of mortality worldwide, often with severe sepsis as the terminal event. Over the last two decades, several studies have reported that in septic patients the adrenal glands respond inappropriately to stimulation, and that the treatment with corticosteroids decreases mortality in such patients. Both cirrhosis and septic shock share many hemodynamic abnormalities such as hyperdynamic circulatory failure, decreased peripheral vascular resistance, increased cardiac output, hypo-responsiveness to vasopressors, increased levels of proinflammatory cytokines [interleukine(IL)-1, IL-6, tumor necrosis factor-alpha] and it has, consequently, been reported that adrenal insufficiency (AI) is common in critically ill cirrhotic patients. AI may also be present in patients with stable cirrhosis without sepsis and in those undergoing liver transplantation. The term hepato-adrenal syndrome defines AI in patients with advanced liver disease with sepsis and/or other complications, and it suggests that it could be a feature of liver disease per se, with a different pathogenesis from that of septic shock. Relative AI is the term given to inadequate cortisol response to stress. More recently, another term is used, namely "critical illness related corticosteroid insufficiency" to define "an inadequate cellular corticosteroid activity for the severity of the patient's illness". The mechanisms of AI in liver cirrhosis are not completely understood, although decreased levels of high-density lipoprotein cholesterol and high levels of proinflammatory cytokines and circulatory endotoxin have been suggested. The prevalence of AI in cirrhotic patients varies widely according to the stage of the liver disease (compensated or decompensated, with or without sepsis), the diagnostic criteria defining AI and the methodology used. The effects of corticosteroid therapy on cirrhotic patients with septic shock and AI are controversial. This review aims to summarize the

For example the liver is, extremely sensitive to changes in insulin or glucagon levels. The liver is the primary organ of iron storage is frequently involved, diabetes is common in patients with iron overload and may be seen in cirrhosis. Chronic infection with HCV is associated with insulin resistance. Thyroid disease often accompanies chronic hepatitis C infection .Anti thyroid autoantibodies are also found in chronic HCV infection. Nonalcoholic liver disease (NAFLDas a most common cause of chronic liver disease in western world ,as well accompanied by Type 2 diabetes and hyperlipidemia. Hypopituitarism and hypothyroidism also have been in NAFLD.The patients with NAFLD and Hypopituitarism may be susceptible to central obesity, dyslipidemia and insulin resistance leading to disease progression. Hepatic cirrhosis as the end stage of chronic liver disease is also associated with hypogonadism and signs of feminization. The peripheral metabolism of steroids is altered in many of hypogonadism, low testosterone level decreased libido, infertility, reduced secondary sex hair and gynecomastia, reduced spermatogenesis and peritubular fibrosis are found in men with cirrhosis .The normal function of the hypothalamic-pituitary gonadal axis is affected in liver disease. In cirrhotic patients the estrogen/androgen ratio is usually increased, the level of testosterone and dihydroepiandosteron are reduced while the estradiol level are normal or slightly elevated, these alterations are dependent on the severity of the liver disease.Succsesfull orthotropic liver transplantation  leads to improvement of the sex hormone disturbances. The pathogenesis of gynecomastia is due to the loss of equilibrium between estrogen and androgen caused by a feminizing state but it is due to increased estrogen precursor in

Enzymatic production is catalyzed by NO synthase (NOS) while entero-salivary circulation of nitrate and nitrite is linked to non-enzymatic formation of NO under acidic pH in the stomach. There is no data on salivary excretion of nitrate and nitrite in cirrhosis. This study was aimed to investigate salivary levels of nitrate and nitrite in a rat model of biliary cirrhosis. Cirrhosis was induced by bile duct ligation (BDL). Four weeks after the operation, submandibular ducts of anesthetized BDL and control rats were cannulated with polyethylene microtube for saliva collection. Assessment of pH, nitrite and nitrate levels was performed in our research. We also investigated NOS expression by real time RT-PCR to estimate eNOS, nNOS and iNOS mRNA levels in the submandibular glands. Salivary pH was significantly lower in BDL rats in comparison to control animals. We also observed a statistically significant increase in salivary levels of nitrite as well as nitrate in BDL rats while there was no elevation in the mRNA expression of nNOS, eNOS, and iNOS in submandibular glands of cirrhotic groups. This indicates that an increased salivary level of nitrite/nitrate is less likely to be linked to increased enzymatic production of NO in the salivary epithelium. It appears that nitrate/nitrite can be transported from the blood stream by submandibular glands and excreted into saliva as entero-salivary circulation, and this mechanism may have been exaggerated during cirrhosis.

    We present the history of a woman suffering from an extensive gastrointestinal bleeding due to liver cirrhosis and chronic pancreatitis. Selective angiogram of the celiac artery revealed a pseudoaneurysm of the gastroduodenal artery caused by inflammatory wall penetration. The life-threatening hemorrhage was completely stopped by embolization with three stainless steel coils after microcatheter engagement of the gastroduodenal artery. The particularity of this case is the restricted embolization of the aneurysm vessel segment, so the collateral circulation of the gastroduodenal and pancreaticoduodenal artery could be preserved.

    AIM:To measure circulating angiotensins at different stages of human cirrhosis and to further evaluate a possible relationship between renin angiotensin system (RAS) components and hemodynamic changes. METHODS:Patients were allocated into 4 groups:mild-to-moderate liver disease (MLD), advanced liverdisease (ALD), patients undergoing liver transplantation,and healthy controls. Blood was collected to determine plasma renin activity (PRA), angiotensin (Ang) Ⅱ , Ang Ⅱ , and Ang-(1-7) levels using radioimmunoassays.During liver transplantation, hemodynamic parameters were determined and blood was simultaneously obtained from the portal vein and radial artery in order to measure RAS components. RESULTS:PRA and angiotensins were elevated in ALD when compared to MLD and controls ( P < 0.05).In contrast, Ang Ⅱ was significantly reduced in MLD. Ang-(1-7)/Ang Ⅱ ratios were increased in MLD when compared to controls and ALD. During transplantation,Ang Ⅱ levels were lower and Ang-(1-7)/Ang Ⅱ ratios were higher in the splanchnic circulation than in the 0.02), whereas the peripheral circulating Ang Ⅱ /Ang Ⅱ ratio was elevated in comparison to splanchnic levels Ang Ⅱ ratios positively correlated with cardiac output ( r = 0.66) and negatively correlated with systemic vascular resistance ( r = -0.70).CONCLUSION:Our findings suggest that the relationship between Ang-(1-7) and Ang Ⅱ may play a role in the hemodynamic changes of human cirrhosis.

    We evaluated the possible alterations produced by liver cholestasis (LC), a model of decompensated liver cirrhosis in sympathetic, sensory and nitrergic nerve function in rat superior mesenteric arteries (SMA). The vasoconstrictor response to electrical field stimulation (EFS) was greater in LC animals. Alpha-adrenoceptor antagonist phentolamine and P2 purinoceptor antagonist suramin decreased this response in LC animals more than in control animals. Both non-specific nitric oxide synthase (NOS) L-NAME and calcitonin gene related peptide (CGRP) (8-37) increased the vasoconstrictor response to EFS more strongly in LC than in control segments. Vasomotor responses to noradrenaline (NA) or CGRP were greater in LC segments, while NO analogue DEA-NO induced a similar vasodilation in both experimental groups. The release of NA was not modified, while those of ATP, nitrite and CGRP were increased in segments from LC. Alpha 1 adrenoceptor, Rho kinase (ROCK) 1 and 2 and total myosin phosphatase (MYPT) expressions were not modified, while alpha 2B adrenoceptor, nNOS expression and nNOS and MYPT phosphorylation were increased by LC. Together, these alterations might counteract the increased splanchnic vasodilation observed in the last phases of decompensated liver cirrhosis. PMID:27484028

    Studies have presented conflicting results regarding the accuracy of ultrasonography (US) for diagnosing portal hypertension (PH). We sought to identify evidence in the literature regarding the accuracy of US for assessing PH in patients with liver cirrhosis. We conducted a systematic review by searching databases, including MEDLINE, EMBASE, and the Cochrane Library, for relevant studies. A total of 14 studies met our inclusion criteria. The US indices were obtained in the portal vein (n = 9), hepatic artery (n = 6), hepatic vein (HV) (n = 4) and other vessels. Using hepatic venous pressure gradient (HVPG) as the reference, the sensitivity (Se) and specificity (Sp) of the portal venous indices were 69-88% and 67-75%, respectively. The correlation coefficients between HVPG and the portal venous indices were approximately 0.296-0.8. No studies assess the Se and Sp of the hepatic arterial indices. The correlation between HVPG and the hepatic arterial indices ranged from 0.01 to 0.83. The Se and Sp of the hepatic venous indices were 75.9-77.8% and 81.8-100%, respectively. In particular, the Se and Sp of HV arrival time for clinically significant PH were 92.7% and 86.7%, respectively. A statistically significant correlation between HVPG and the hepatic venous indices was observed (0.545-0.649). Some US indices, such as HV, exhibited an increased accuracy for diagnosing PH. These indices may be useful in clinical practice for the detection of significant PH.

    Full Text Available BACKGROUND: There is increasing recognition that pulmonary artery stiffness is an important determinant of right ventricular (RV afterload in pulmonary arterial hypertension (PAH. We used intravascular ultrasound (IVUS to evaluate the mechanical properties of the elastic pulmonary arteries (PA in subjects with PAH, and assessed the effects of PAH-specific therapy on indices of arterial stiffness. METHOD: Using IVUS and simultaneous right heart catheterisation, 20 pulmonary segments in 8 PAH subjects and 12 pulmonary segments in 8 controls were studied to determine their compliance, distensibility, elastic modulus and stiffness index β. PAH subjects underwent repeat IVUS examinations after 6-months of bosentan therapy. RESULTS: AT BASELINE, PAH SUBJECTS DEMONSTRATED GREATER STIFFNESS IN ALL MEASURED INDICES COMPARED TO CONTROLS: compliance (1.50±0.11×10(-2 mm(2/mmHg vs 4.49±0.43×10(-2 mm(2/mmHg, p<0.0001, distensibility (0.32±0.03%/mmHg vs 1.18±0.13%/mmHg, p<0.0001, elastic modulus (720±64 mmHg vs 198±19 mmHg, p<0.0001, and stiffness index β (15.0±1.4 vs 11.0±0.7, p = 0.046. Strong inverse exponential associations existed between mean pulmonary artery pressure and compliance (r(2 = 0.82, p<0.0001, and also between mean PAP and distensibility (r(2 = 0.79, p = 0.002. Bosentan therapy, for 6-months, was not associated with any significant changes in all indices of PA stiffness. CONCLUSION: Increased stiffness occurs in the proximal elastic PA in patients with PAH and contributes to the pathogenesis RV failure. Bosentan therapy may not be effective at improving PA stiffness.

    Full Text Available Abstract Introduction Exposure to air pollution is associated with increased cardiovascular morbidity, although the underlying mechanisms are unclear. Vascular dysfunction reduces arterial compliance and increases central arterial pressure and left ventricular after-load. We determined the effect of diesel exhaust exposure on arterial compliance using a validated non-invasive measure of arterial stiffness. Methods In a double-blind randomized fashion, 12 healthy volunteers were exposed to diesel exhaust (approximately 350 μg/m3 or filtered air for one hour during moderate exercise. Arterial stiffness was measured using applanation tonometry at the radial artery for pulse wave analysis (PWA, as well as at the femoral and carotid arteries for pulse wave velocity (PWV. PWA was performed 10, 20 and 30 min, and carotid-femoral PWV 40 min, post-exposure. Augmentation pressure (AP, augmentation index (AIx and time to wave reflection (Tr were calculated. Results Blood pressure, AP and AIx were generally low reflecting compliant arteries. In comparison to filtered air, diesel exhaust exposure induced an increase in AP of 2.5 mmHg (p = 0.02 and in AIx of 7.8% (p = 0.01, along with a 16 ms reduction in Tr (p = 0.03, 10 minutes post-exposure. Conclusion Acute exposure to diesel exhaust is associated with an immediate and transient increase in arterial stiffness. This may, in part, explain the increased risk for cardiovascular disease associated with air pollution exposure. If our findings are confirmed in larger cohorts of susceptible populations, this simple non-invasive method of assessing arterial stiffness may become a useful technique in measuring the impact of real world exposures to combustion derived-air pollution.

    Regulatory oversight of capital markets has intensified in recent years, with a particular emphasis on expanding financial transparency. A notable instance is efforts by the Financial Accounting Standards Board that push firms to identify and report performance of individual business units...... (segments). This paper seeks to address short-run and long-run consequences of stringent enforcement of and uniform compliance with these segment disclosure standards. To do so, we develop a parsimonious model wherein a regulatory agency promulgates disclosure standards and either permits voluntary...... compliance or mandates strict compliance from firms. Under voluntary compliance, a firm is able to credibly withhold individual segment information from its competitors by disclosing data only at the aggregate firm level. Consistent with regulatory hopes, we show that mandatory compliance enhances welfare...

    BACKGROUND & AIMS: It is unclear whether patients with hepatic encephalopathy (HE) have disturbed brain oxygen metabolism and blood flow. METHODS: We measured cerebral oxygen metabolism rate (CMRO(2)) by using (15)O-oxygen positron emission tomography (PET), and cerebral blood flow (CBF) by using....../min in patients with HE, 0.47 +/- 0.02 in patients without HE, and 0.49 +/- 0.03 in healthy subjects. CMRO(2) and CBF were correlated, and both variables correlated negatively with arterial ammonia concentration. Analysis of regional values, using individual magnetic resonance co-registrations, showed...... that the reductions in CMRO(2) and CBF in patients with HE were essentially generalized throughout the brain. CONCLUSIONS: The observations imply that reduced cerebral oxygen consumption and blood flow in cirrhotic patients with an acute episode of overt HE are associated with HE and not cirrhosis as such...

    Full Text Available Abstract Background Studies have shown psychological distress in patients with cirrhosis, yet no studies have evaluated the laboratory and physiologic correlates of psychological symptoms in cirrhosis. This study therefore measured both biochemistry data and heart rate variability (HRV analyses, and aimed to identify the physiologic correlates of depression, anxiety, and poor sleep in cirrhosis. Methods A total of 125 patients with cirrhosis and 55 healthy subjects were recruited. Each subject was assessed through routine biochemistry, 5-minutes ECG monitoring, and psychological ratings of depression, anxiety, and sleep. HRV analysis were used to evaluate autonomic functions. The relationship between depression, sleep, and physiologic correlates was assessed using a multiple regression analysis and stepwise method, controlling for age, duration of illness, and severity of cirrhosis. Results Reduced vagal-related HRV was found in patients with severe liver cirrhosis. Severity of cirrhosis measured by the Child-Pugh score was not correlated with depression or anxiety, and only had a weak correlation with poor sleep. The psychological distress in cirrhosis such as depression, anxiety, and insomnia were correlated specifically to increased levels of aspartate aminotransferase (AST, increased ratios of low frequency to high frequency power, or reduced nonlinear properties of HRV (α1 exponent of detrended fluctuation analysis. Conclusions Increased serum AST and abnormal autonomic nervous activities by HRV analysis were associated with psychological distress in cirrhosis. Because AST is an important mediator of inflammatory process, further research is needed to delineate the role of inflammation in the cirrhosis comorbid with depression.

    Acetylcholine's effect on the distribution of vascular resistance and compliance in the canine pulmonary circulation was determined under control and elevated vascular tone by the arterial, venous, and double occlusion techniques in isolated blood-perfused dog lungs at both constant flow and constant pressure. Large and small blood vessel resistances and compliances were studied in lungs given concentrations of acetylcholine ranging from 2.0 ng/ml to 200 micrograms/ml. The results of this study indicate that acetylcholine dilates large arteries at low concentrations (less than or equal to 20 ng/ml) and constricts small and large veins at concentrations of at least 2 micrograms/ml. Characterization of acetylcholine's effects at constant pulmonary blood flow indicates that 1) large artery vasodilation may be endothelial-derived relaxing factor-mediated because the dilation is blocked with methylene blue; 2) a vasodilator of the arachidonic acid cascade (blocked by ibuprofen), probably prostacyclin, lessens acetylcholine's pressor effects; 3) when vascular tone was increased, acetylcholine's hemodynamic effects were attenuated; and 4) acetylcholine decreased middle compartment and large vessle compliance under control but not elevated vascular tone. Under constant pressure at control vascular tone acetylcholine increases resistance in all segments except the large artery, and at elevated vascular tone the pressor effects were enhanced, and large artery resistance was increased.

    We sought to explore the pulmonary haemodynamic changes in rheumatic mitral stenosis patients with secondary pulmonary hypertension. The pulmonary artery resistance and compliance of 35 patients with rheumatic mitral stenosis and 12 controls without cardiopulmonary vascular disease were evaluated by using an improved method, which is based on making calculations with parameters obtained from right heart catheterisation. The results are as follows: (1) pulmonary artery compliance in patients with secondary pulmonary hypertension was significantly lower than that of the control group (P0.05) The walls of pulmonary artery vessels in patients with pulmonary hypertension secondary to rheumatic mitral stenosis appeared to be remodelled by varying degrees as indicated by their haemodynamic properties. Structural remodelling may be a factor affecting preoperative pulmonary artery pressure. Mitral stenosis patients with severe pulmonary hypertension have significantly lower responses to sodium nitroprusside possibly due to aggradation and deposition of collagen in the artery walls, decreasing constriction and dilation, or atrophy of smooth muscle cells.

    We have defined a novel cerebral hemodynamic index, a time constant of the cerebral arterial bed (τ), the product of arterial compliance (C(a)) and cerebrovascular resistance (CVR). C(a) and CVR were calculated based on the relationship between pulsatile arterial blood pressure (ABP) and transcranial Doppler cerebral blood flow velocity. This new parameter theoretically estimates how fast the cerebral arterial bed is filled by blood volume after a sudden change in ABP during one cardiac cycle. We have explored this concept in 11 volunteers and in 25 patients with severe stenosis of the internal carotid artery (ICA). An additional group of 15 subjects with non-vascular dementia was studied to assess potential age dependency of τ. The τ was shorter (p = 0.011) in ICA stenosis, both unilateral (τ = 0.18 ± 0.04 s) and bilateral (τ = 0.16 ± 0.03 s), than in controls (τ = 0.22 ± 0.0 s). The τ correlated with the degree of stenosis (R = -0.62, p = 0.001). In controls, τ was independent of age. Further study during cerebrovascular reactivity tests is needed to establish the usefulness of τ for quantitative estimation of haemodynamics in cerebrovascular disease.

    Although uncommon during pregnancy, cirrhosis results in multiple medical complications impacting both mother and fetus. Previous reports suggest liver dysfunction in pregnancy causes accumulation of neurotoxins within the maternal compartment that increases neonatal morbidity through placental transfer. We present a case of a 36-year-old G2P1 female with history of biliary cirrhosis presenting at 32-weeks' gestation with hepatic congestion progressing to hepatic encephalopathy prompting delivery. Umbilical cord sampling and postnatal infant testing demonstrated elevated ammonia levels which resolved by 12 hours of life without intervention. At discharge, the infant did not demonstrate evidence of neurologic deficit. We conclude that acute maternal hepatic encephalopathy and hyperammonemia due to chronic liver disease do not portend adverse neonatal outcomes, notably encephalopathy.

    2016-01-01

    Proton pump inhibitors(PPIs) represent one of the most extensively prescribed classes of drugs in general and in patients with liver cirrhosis. Many prescriptions are made without a clear adherence to standard indications. As a class of ordinarily well tolerated drug, PPIs are not free of side-effects and concerns have been raised about a possible role for PPIs in predisposing patients to an increased risk of bacterial infections and sepsis. As evidences of different power are accumulating on this topic, prospective studies are needed to reach a more universal agreement, but definitely more attention is needed by prescribers in being more adherent to the few recognized indications for the use of PPIs, particularly in patients with liver cirrhosis. Otherwise, doctors could run the risk of being accused of "abused" prescription.

    2016-01-01

    The main function of erythropoietin (EPO) is to maintain red blood cell mass, but in recent years, increasing evidence has suggested a wider biological role not solely related to erythropoiesis, e.g. angiogenesis and tissue protection. EPO is produced in the liver during fetal life, but the main...... production shifts to the kidney after birth. The liver maintains a production capacity of up to 10% of the total EPO synthesis in healthy controls, but can be up-regulated to 90-100%. However, the hepatic EPO synthesis has been shown not to be adequate for correction of anemia in the absence of renal......-derived EPO. Elevated circulating EPO has been reported in a number of diseases, but data from cirrhotic patients are sparse and the level of plasma EPO in patients with cirrhosis is controversial. Cirrhosis is characterized by liver fibrosis, hepatic dysfunction and the release of proinflammatory cytokines...

    OBJECTIVE: It is currently discussed if beta-blockers exert harmful effects and increase mortality in patients with cirrhosis and refractory ascites. In this study, we provide an overview of the available literature in this field in combination with a retrospective analysis of 61 patients...... trials (9 trials on propranolol, 1 case-control study and 4 retrospective analyses) were identified. One trial suggested an increased mortality in patients treated with beta-blockers and refractory ascites. The results of the remaining trials were inconclusive. No increase in mortality among beta-blocker......-treated patients was found in the present retrospective analysis. CONCLUSIONS: Treatment with beta-blockers may increase mortality in patients with cirrhosis and refractory ascites. However, the current evidence is sparse and high-quality studies are warranted to clarify the matter....

    Although both primary biliary cirrhosis (PBC) and idiopathic thrombocytopenic purpura (ITP) are autoimmune diseases, the association of the 2 diseases is rare. Here, we report a case of ITP that developed during the follow-up of PBC in a 74-yearold man. The patient had been diagnosed with PBC 12 years previously, and had received treatment with ursodeoxycholic acid. The platelet count decreased from approximately 60 × 109/L to 8 × 109/L, and the association of decompensated liver cirrhosis (PBC) with ITP was diagnosed. Steroid and immune gamma globulin therapy were successful in increasing the platelet count.Interestingly, human leukocyte antigen genotyping detected the alleles DQBI*0601 and DRBI*0803, which are related to both PBC and ITP in Japanese patients.This case suggests common immunogenetic factors might be involved in the development of PBC and ITP.

    AIM: To analyze the relationship between plasmaand platelet serotonin levels and the degree of liverinsufficiency.METHODS: The prospective study included 30 patients with liver cirrhosis and 30 healthy controls. The degree of liver failure was assessed according to the Child-Pugh classification. Platelet and platelet poor plasma serotonin levels were determined.RESULTS: The mean plasma serotonin level was higher in liver cirrhosis patients than in healthy subjects (215.0± 26.1 vs 63.1 ± 18.1 nmol/L; P < 0.0001). The mean platelet serotonin content was not significantly different in patients with liver cirrhosis compared with healthy individuals (4.8 ± 0.6; 4.2 ± 0.3 nmol/platelet; P > 0.05).Plasma serotonin levels were significantly higher in ChildPugh grade A/B than in grade C patients (246.8 ± 35.0vs132.3 ± 30.7 nmol/L; P < 0.05). However, platelet serotonin content was not significantly different between Child-Pugh grade C and grade A/B (4.6 ± 0.7 vs 5.2 ± 0.8nmol/platelet; P > 0.05).CONCLUSION: Plasma serotonin levels are significantly higher in patients with cirrhosis than in the controls and represent the degree of liver insufficiency. In addition,platelet poor plasma serotonin estimation is a better marker for liver insufficiency than platelet serotonin content.

    2011-01-01

    Livercirrhosis can be complicated by a hyperdynamic circulatory syndrome. This is due to translocation of bacteria and bacterial product (bacterial DNA and endotoxins), which stimulate the splanchnic nitric oxide synthase and leads to splanchnic vasodilatation and haemodynamic derangement....... This review focuses on how broad spectrum antibiotics can ameliorate the haemodynamic consequences of bacterial translocation. It is possible that the use of broad spectrum antibiotics in the future may be used to prevent other complications of liver cirrhosis than spontaneous bacterial peritonitis...

    The therapeutic effectiveness of nutritional support in the treatment of severe chronic hepatitis and posthepatitic cirrhosis was evaluated. 143 patients with severe chronic hepatitis and 83 with posthepatitic cirrhosis were evaluated with SGA for assessing the nutritional status before the treatment. Patients with severe chronic hepatitis were divided into three groups: group A subject to enteral nutrition (EN) and parenteral nutrition (PN), group B subject to comprehensive treatment (CT) +PN; group C subject to CT+ EN. The patients with posthepatitic cirrhosis were divided into two groups: group D receiving CT and group E receiving CT+PN+EN. The function of liver and kidney and nutritional status were monitored to assess the therapy in 6 weeks. The results showed before treatment, over 90 % patients had moderate to severe malnutrition. After nutritional support, the liver function (ALT, T-biil) and nutritional status (TP, TC) in group A was improved significantly as compared with that in groups B and C (P<0.05). Compared with group D,the values of TP and Alb were increased significantly in group E (P<0.05), but the levels of ALT, AST and T-bil had no obvious change. It was suggested that most patients with severe chronic hepatitis or posthepatitic cirrhosis had malnutrition to varying degrees. The nutritional support treatment could obviously improve the nutritional status of these patients, and was helpful to ameliorate the liver function of the patients with severe chronic hepatitis. Among the methods of nutritional support treatment, PN combined with EN had the best effectiveness.

    Prevalence of chronic liver diseases, including liver cirrhosis, is increasing worldwide. The nutritional state assessment in these patients is complicated, and besides anthropometry is based on several other tools in order to be more accurate. Specific dietary recommendations are needed in patients with chronic liver diseases in order to help prevent and treat liver decompensation because malnutrition is an independent predictor of mortality. This review focuses on essential aspects in the nutritional assessment of cirrhotic patients and some general recommendations for their treatment.

  5. Muscle Cramps: A ‘Complication‘ of Cirrhosis

    OpenAIRE

    Marotta, Paul J; Graziadei, Ivo W; Cameron N Ghent

    2000-01-01

    Muscle cramps are a common complaint in clinical practice. They are associated with various metabolic, endocrine, neurological and electrolyte abnormalities. A variety of hypotheses have been generated to explain the cause of muscle cramping, yet none has been able to support a consistent pathophysiological mechanism. Muscle cramps are painful, involuntary contractions of skeletal muscle. They occur frequently in individuals with cirrhosis, regardless of the etiology, and are thought to be a ...

    Antimitochondrial, anti-gp210, anti-sp100, and anticentromere antibodies are specifically detected in primary biliary cirrhosis (PBC). In clinical practice, they are useful for the diagnosis of PBC or for evaluating disease severity, clinical phenotype, and long-term outcome. In the typical or classical form of PBC which shows slow progressive loss of small bile ducts with a parallel increase in liver fibrosis, anti-gp210 antibodies are a strong risk factor for progression to jaundice and hep...

    Full Text Available Metabolic syndrome is a common clinical condition often associated with hepatic steatosis and sometimes with mild transaminases and gamma-glutamyl transpeptidase increase. We report a case of a 45-years-old female, with mild increase of ALT, who was followed-up in our Department. A liver biopsy was then performed when an atorvastatin-induced ALT flare, as well as a positive antinuclear antibody appearance, occurred. A picture of steatohepatitis with sever fibrosis and cirrhosis was found. A caloric restriction with physical activity as well as the use of metformin were recommended. In the following 6 years the patient develops a decompensated cirrhosis and was referred to a Transplant Unit. This case suggests that non alcoholic steatohepatitis and cirrhosis can develop in patients with metabolic syndrome, especially when other cofactors of liver damage, as alcohol, may be superimposed. In non alcoholic steatohepatitis liver biopsy is mandatory to stage the disease. Moreover it is always recommended when different causes may concur to liver damage in the same patient.

    Liver cirrhosis, a devastating liver fibrosis caused by hepatitis/inflammation or tumors, is a major comorbid factor in known surgery fields, such as cardiovascular and abdominal surgeries. It is important to review possible comorbid results in neurosurgical procedures in cirrhotic patients. In the reviewed literature, ChildPugh and model for end-stage liver disease scores are commonly used in the assessment of surgical risks for cirrhotic patients undergoing abdominal, cardiovascular or neurosurgical procedures. The major categories of neurosurgery are traumatic brain injury(TBI), spontaneous intracranial hemorrhage(SICH), brain tumors, and spinal instrumentation procedures. TBI was reported with surgical mortality as high as 34.5% and a complication rate of 87.2%. For SICH, mortality ranged from 22.7% to 47.0%, while complications were reported to be 43.2%. Less is discussed in brain tumor patients; still the postoperative hemorrhage rate approached 26.7%. In spinal fusion instrumentation procedures, the complication rate was as high as 41.0%. Preoperative assessment and correction could possibly decrease complications such as hemorrhage, wound infection and other cirrhosis-related complications(renal, pulmonary, ascites and encephalopathy). In this study, we reviewed the neurosurgical-related literature with regard to liver cirrhosis as a prognostic factor influencing neurosurgical outcomes.

  10. Influence of unrecorded alcohol consumption on liver cirrhosis mortality.

    Unrecorded alcohol includes illegally distributed alcohol as well as homemade or surrogate alcohol which is unintended for consumption by humans (e.g., cosmetics containing alcohol). The highest unrecorded alcohol consumption occurs in Eastern Europe and some of these countries have an over proportional liver cirrhosis mortality. Compounds besides ethanol have been hypothesized as being responsible for this observation. On the other hand, chemical investigations were unable to prove that unrecorded alcohol regularly contains contaminants above toxicological thresholds. However, illegally produced spirits regularly contain higher percentages of alcohol (above 45% by volume), but for considerably less costs compared with licit beverages, potentially causing more problematic patterns of drinking. In this review, it is investigated whether patterns of drinking rather than product composition can explain the liver cirrhosis mortality rates. Statistical examination of World Health Organization country data shows that the originally detected correlation of the percentage of unrecorded alcohol consumption and liver cirrhosis mortality rates disappears when the data is adjusted for the prevalence of heavy episodic drinking. It may be concluded that there is currently a lack of data to demonstrate causality between the composition of illicit spirits (e.g., higher levels of certain contaminants in home-produced products) and liver toxicity on a population scale. Exceptions may be cases of poisoning with antiseptic liquids containing compounds such as polyhexamethyleneguanidine, which were reported to be consumed as surrogate alcohol in Russia, leading to an outbreak of acute cholestatic liver injury, histologically different from conventional alcoholic liver disease.

    Full Text Available Objective: Correlated responses are common in repeatedly measured clinical trial data. The generalized estimating equations (GEE method is popular for analyzing correlated responses. It is important to select a proper working correlation matrix because an inappropriate choice will lead to inefficient parameter estimation. In this paper, we examine criterion of quasi-likelihood information criterion (QIC for selecting a working correlation structure, and have compared with the performance of the correlation information criteria (CIC of the correlation structures on liver cirrhosis patients. Material and Methods: The computation code for CIC is performed into open source software R. The covariates like therapy and visit are used to predict Meld scores (It is continuous disease severities scale with highly predictive of the risk of dying from liver cirrhosis in GEE model to examine the performance of QIC and CIC after considering three different working correlation structures. Results: The GEE model has been performed to compare QIC and CIC after considering three working correlation structure. In case of AR (1 correlation structure, it is found that similar regression arameter estimates are observed for both information criteria techniques. Conclusion: The study indicates that the CIC is useful for selecting appropriate correlation structures for liver cirrhosis data from phase III clinical trial.

    Full Text Available Background: Khat chewing is common especially among men in East Africa and Yemen. It is generally viewed by the populace as a benign social custom. Several studies of ethnic Somali immigrants to Western countries suggest an association between khat chewing and hepatotoxicity, but the risk of hepatotoxicity related to khat chewing within African settings is not documented.Aim: To identify and describe liver disease without evidence of alcohol exposure or infectious etiology in khat chewers.Settings: A university-affiliated teaching hospital in Somaliland.Methods: Cases of cirrhosis of unknown cause were identified from the clinical practice of Al Hayatt Hospital in Borama, Somaliland, during 14 months beginning December 2012.Results: Eight Somali men aged 27–70 years living in Somaliland were identified with cirrhosis of otherwise unknown cause. All chewed khat habitually for many years (15–128 bundles per day times years of use. A liver biopsy of one man was consistent with khat hepatotoxicity. Four of the eight men died during the study period.Conclusion: Khat chewing may be associated with health consequences including severe hepatotoxicity with cirrhosis.

    The prognosis of decompensated cirrhosis resulting from chronic hepatitis B is poor, and the benefits of treatment with interferon are outweighed by serious side effects and by the risk of fatal exacerbation of disease activity. Lamivudine rapidly reduces hepatitis B virus (HBV)-DNA in serum to undetectable levels. We have treated 35 patients with chronic hepatitis B and decompensated cirrhosis with lamivudine 100 mg or 150 mg orally once daily. Pretreatment, all were positive for HBV-DNA in serum. Ten had Child-Pugh class B and 25 had Child-Pugh class C liver disease. Seven patients underwent liver transplantation within 6 months of treatment initiation, 5 patients died within 6 months, and 23 patients were treated for at least 6 months (mean = 19 months). In a majority of these 23 cases, there was a slow but marked improvement in liver function, which was most apparent after 9 months of treatment, with a decrease in serum bilirubin from 67 +/- 13 to 30 +/- 4 micromol/L (P decompensated HBV cirrhosis, but the long-term benefits remain uncertain.

  15. New determinants of prognosis in bacterial infections in cirrhosis

    Acevedo, Juan; Fernández, Javier

    2014-01-01

    Despite major advances in the knowledge and management of liver diseases achieved in recent decades, decompensation of cirrhosis still carries a high burden of morbidity and mortality. Bacterial infections are one of the main causes of decompensation. It is very important for clinical management to be aware of the population with the highest risk of poor outcome. This review deals with the new determinants of prognosis in patients with cirrhosis and bacterial infections reported recently. Emergence of multiresistant bacteria has led to an increasing failure rate of the standard empirical antibiotic therapy recommended by international guidelines. Moreover, it has been recently reported that endothelial dysfunction is associated with the degree of liver dysfunction and, in infected patients, with the degree of sepsis. It has also been reported that relative adrenal insufficiency is frequent in the non-critically ill cirrhotic population and it is associated with a higher risk of developing infection, severe sepsis, hepatorenal syndrome and death. We advise a change in the standard empirical antibiotic therapy in patients with high risk for multiresistant infections and also to take into account endothelial and adrenal dysfunction in prognostic models in hospitalized patients with decompensated cirrhosis.

    We performed a prospective study to evaluate the ability of L-carnitine, which is involved in the β-oxidation of fatty acids, to reduce muscle cramps in patients with cirrhosis. Consecutive patients with cirrhosis and muscle cramps were given L-carnitine 300 mg, 3 times/day (900 mg/day, n = 19) or 4 times/day (1200 mg/day, n = 23) for 8 weeks. The frequency of muscle cramps was assessed by questionnaires, and the degree of muscle cramping was assessed by using the visual analogue scale (VAS). Muscle cramping was reduced in 88.1% of all subjects at the end of the 8-week study period and disappeared for 28.6% of patients. Overall VAS scores decreased significantly from 69.9 ± 22.5 at baseline to 26.2 ± 29.1 after 8 weeks (P muscle cramps after 8 weeks (43.5% in the 1200 mg/day group vs 10.5% in the 900 mg/day group, P = .037) and VAS scores at 8 weeks (9.9 ± 13.5 in the 1200 mg/day group vs 39.6 ± 31.9 in the 900 mg/day group, P = .003). No adverse events were reported. Therefore, L-carnitine appears to be safe and effective for reducing liver cramps in patients with cirrhosis.

    Background Renal hemodynamic measurements are complicated to perform in patients with cirrhosis; yet they provide the best measure of risk to predict hepatorenal syndrome (HRS). Currently, there are no established biomarkers of altered renal hemodynamics in cirrhosis validated by measured renal hemodynamics. Methods In this pilot study, simultaneous measurements of glomerular filtration rate (GFR), renal plasma flow (RPF), renal resistive indices and biomarkers were performed to evaluate renal hemodynamic alterations in 10 patients with cirrhosis (3 patients without ascites, 5 with diuretic sensitive and 2 diuretic refractory ascites). Results Patients with diuretic refractory ascites had the lowest mean GFR (36.5 ml/min/1.73m2) and RPF (133.6 ml/min/1.73m2) when compared to those without ascites (GFR=82.9 ml/min/1.73m2, RPF=229.9 ml/min/1.73m2) and with diuretic-sensitive ascites (GFR=82.3 ml/min/1.73m2, RPF=344.1 ml/min/1.73m2). A higher mean filtration fraction (FF= GFR/RPF=0.36) was noted among those without ascites compared to those with ascites. Higher FF in patients without ascites is most likely secondary to the vasoconstriction in the efferent glomerular arterioles (normal FF≃0.20). In general, renal resistive indices were inversely related to FF. While patients with ascites had lower FF and higher right kidney main and arcuate artery resistive indices, those without ascites had higher FF and lower right kidney main and arcuate artery resistive indices. While cystatin C and beta-2 microglobulin performed better compared to Cr in estimating RPF; beta-trace protein, beta-2 microglobulin, SDMA, and (SDMA+ADMA) performed better in estimating right kidney arcuate artery resistive index. Conclusion The results of this pilot study showed that identification of non-invasive biomarkers of reduced RPF and increased renal resistive indices can identify cirrhotics at risk for HRS at a stage more amenable to therapeutic intervention, and reduce mortality from kidney

    Turner's syndrome is a genetic disorder of the sex chromosomes (e.g., 45,X or 45,X/46,XX) that manifests as various congenital anomalies. Despite its numerous extragonadal manifestations and frequent accompanying abnormalities in liver function tests, liver cirrhosis associated with Turner's syndrome has not been reported in Korea. Moreover, pulmonary arteriovenous malformations (PAVMs) have rarely been reported in association with liver cirrhosis, but there have been no reports of PAVMs occurring in cryptogenic liver cirrhosis associated with Turner's syndrome. We report a case of PAVM that occurred in cryptogenic liver cirrhosis associated with Turner's syndrome.

    1994-05-01

    The Hazardous Waste Compliance Program Plan (HWCPP) describes how the Rocky Flats Plant institutes a more effective waste management program designed to achieve and maintain strict adherence to the Resource Conservation and Recovery Act (RCRA) requirements. Emphasis is given to improve integration of line operations with programmatic and functional support activities necessary to achieve physical compliance to RCRA regulated equipment, facilities and operations at the floor level. This program focuses on specific activities occurring or which need to occur within buildings containing RCRA regulated units and activities. The plan describes a new approach to achieving and maintaining compliance. This approach concentrates authority and accountability for compliance with the line operating personnel, with support provided from the programmatic functions. This approach requires a higher degree of integration and coordination between operating and program support organizations. The principal changes in emphases are; (1) increased line operations involvement, knowledge and accountability in compliance activities, (2) improved management systems to identify, correct and/or avoid deficiencies and (3) enhanced management attention and employee awareness of compliance related matters.

    1992-08-01

    To assess the hemodynamic status of patients with compensated cirrhosis, mean arterial pressure, cardiac index and peripheral vascular resistance and markers of central (plasma concentrations of atrial natriuretic factor) and arterial volemia (plasma norepinephrine concentration, plasma renin activity) were studied in 10 patients and 10 healthy control subjects under steady-state conditions (after 2 hr of standing) and after assumption of the supine position (30, 60, and 120 min). After standing, neither hemodynamics nor markers of effective volemia differed significantly between controls and patients. By evaluating the areas under the curve during the 2 hr of supine posture, the increase in cardiac output and plasma natriuretic factor and the decrease in peripheral vascular resistance were greater in patients (2.59 +/- 0.43 [S.E.M.] L/min/hr; 32.8 +/- 7.2 pg/ml/hr -1,103 +/- 248.4 dyn.sec/cm5/hr, respectively) than in controls (0.53 +/- 0.24 L/min/hr, p = 0.005; 17.4 +/- 4.7 pg/ml/hr, p = 0.005; -265.5 +/- 206.2 dyn.sec/cm5/hr, p = 0.02). The declines in heart rate, plasma norepinephrine concentration and plasma renin activity did not differ significantly. Mean arterial pressure did not significantly change. Our results suggest that during periods of upright posture, cirrhotic patients in the preascitic stage, who are known to have expanded blood volume, compensate for dilatation of the splanchnic vascular bed through total hypervolemia. The latter becomes excessive during recumbency, leading to supernormal increases in venous return, central volemia and cardiac index. The decline in peripheral vascular resistance appears to be a compensatory mechanism to maintain steady arterial blood pressure.(ABSTRACT TRUNCATED AT 250 WORDS)

    Full Text Available OBJECTIVE: To evaluate elastic properties of conduit arteries in asymptomatic patients who have severe chronic aortic regurgitation. METHODS: Twelve healthy volunteers aged 30±1 years (control group and 14 asymptomatic patients with severe aortic regurgitation aged 29±2 years and left ventricular ejection fraction of 0.61±0.02 (radioisotope ventriculography were studied. High-resolution ultrasonography was performed to measure the systolic and diastolic diameters of the common carotid artery. Simultaneous measurement of blood pressure enabled the calculation of arterial compliance and distensibility. RESULTS: No differences were observed between patients with aortic regurgitation and the control group concerning age, sex, body surface, and mean blood pressure. Pulse pressure was significantly higher in the aortic regurgitation group compared with that in the control group (78±3 versus 48±1mmHg, P<0.01. Arterial compliance and distensibility were significantly greater in the aortic regurgitation group compared with that in the control group (11.0±0.8 versus 8.1±0.7 10-10 N-1 m4, P=0.01 e and 39.3±2.6 versus 31.1±2.0 10-6 N-1 m², P=0.02, respectively. CONCLUSION: Patients with chronic aortic regurgitation have increased arterial distensibility. Greater vascular compliance, to lessen the impact of systolic volume ejected into conduit arteries, represents a compensatory mechanism in left ventricular and arterial system coupling.

    Image based modeling is finding increasing relevance in assisting diagnosis of Pulmonary Valve-Vasculature Dysfunction (PVD) in congenital heart disease patients. This research presents compliant artery - blood interaction in a patient specific Pulmonary Artery (PA) model. This is an improvement over our previous numerical studies which assumed rigid walled arteries. The impedance of the arteries and the energy transfer from the Right Ventricle (RV) to PA is governed by compliance, which in turn is influenced by the level of pre-stress in the arteries. In order to evaluate the pre-stress, an inverse algorithm was developed using an in-house script written in MATLAB and Python, and implemented using the Finite Element Method (FEM). This analysis used a patient specific material model developed by our group, in conjunction with measured pressure (invasive) and velocity (non-invasive) values. The analysis was performed on an FEM solver, and preliminary results indicated that the Main PA (MPA) exhibited higher compliance as well as increased hysteresis over the cardiac cycle when compared with the Left PA (LPA). The computed compliance values for the MPA and LPA were 14% and 34% lesser than the corresponding measured values. Further, the computed pressure drop and flow waveforms were in close agreement with the measured values. In conclusion, compliant artery - blood interaction models of patient specific geometries can play an important role in hemodynamics based diagnosis of PVD.

    AIM: To evaluate treatment safety and hemodynamic changes during a single 6-h treatment with the Prometheus? liver assist system in a randomized, controlled study.METHODS: Twenty-four patients were randomized to either the study group or to one of two control groups: Fractionated Plasma Separation Adsorption and Dialysis, Prometheus? system (Study group; n = 8); Molecular Adsorbent Recirculation System (MARS)? (Control group 1, n = 8); or hemodialysis (Control group 2; n = 8). All patients included in the study had decompensated cirrhosis at the time of the inclusion into the study. Circulatory changes were monitored with a Swan-Ganz catheter and bilirubin and creatinine were monitored as measures of protein-bound and water-soluble toxins.RESULTS: Systemic hemodynamics did not differ between treatment and control groups apart from an increase in arterial pressure in the MARS group (P = 0.008). No adverse effects were observed in any of the groups. Creatinine levels significantly decreased in the MARS group (P = 0.03) and hemodialysis group (P = 0.04). Platelet count deceased in the Prometheus group (P = 0.04).CONCLUSION: Extra-corporal liver support with Prometheus is proven to be safe in patients with end-stage liver disease but does not exert the beneficial effects on arterial pressure as seen in the MARS group.

    AIM: Recent studies have demonstrated that obesity is the common feature of cryptogenic cirrhosis (CC) and non-alcoholic steatohepatitis. However, there is little information on CC in the region where obesity is not prevalent.METHODS: The clinical features, and the liver-related morbidity and mortality of CC were analyzed in Japan where the prevalence of obesity is low. Among 652 cirrhotic patients, we identified 29 patients (4.4%) with CC.Of these, 24 CC patients who were followed up for more than 6 months were compared in a case-control study with age-, sex-, and Child-Pugh score-matched controls having cirrhosis of viral etiology.RESULTS: Obesity (BMI≥25 kg/m2), diabetes mellitus,and hypertriglyceridemia were more frequent, and the visceral fat area was larger in the CC patients than in the controls. The indices of insulin resistance were higher and the serum aminotransferase levels were lower in the CC patients than in the controls. Logistic regression analysis identified the elevated hemoglobin A1c, BMI ≥ 25kg/m2, and normal aminotransferase levels as independent predictors of CC. Kaplan-Meier analysis demonstrated lower occurrence of hepatocellular carcinoma and higher survival rate in the CC than in the controls in contrast to the similar cumulative probability of liverrelated morbidity between those groups.CONCLUSION: CC more frequently presents with the clinical features suggestive of non-alcoholic steatohepatitis compared with controls even in the region where obesity is not prevalent. The lower occurrence of hepatocellular carcinoma and higher survival rate may indicate an indolent clinical course in CC as compared with viral cirrhosis.

    Full Text Available Objective: Etiopathogenesis of cryptogenic cirrhosis (CC is not yet well established. Up to 20% of non-alcoholic fatty liver disease (NAFLD may progress to cirrhosis, mostly termed as cryptogenic. Insulin resistance and altered metabolic parameters form a major pathogenic link between NAFLD and CC. CC may thus be actually a metabolic liver disease. Materials and Methods: Thirty-four patients of CC and 32 patients having cirrhosis due to chronic hepatitis B (Hep B were assessed in a cross-sectional study in a tertiary hospital for insulin resistance, % β-cell activity, obesity indices, plasma glucose, lipid profiles, and many other parameters. Results: CC patients had higher homeostasis model assessment (HOMA-IR compared to Hep B group (P = 0.000016. A positive correlation between IR values and Child-Pugh score among CC patients was found ("r" = 0.87; P < 0.00001. Out of 34 CC patients, 15 (44.1% had obesity contrary to 6 (18.8% in the control group (P = 0.0022. Differences were observed in subcutaneous fat (P = 0.0022, intra-abdominal fat (P = 0.0055, waist circumference (P = 0.014, and percentage body fat (P = 0.047 between the two groups. Significant differences were observed in the levels of triglyceride, total cholesterol, and very low density lipoprotein (VLDL. Conclusion: Most of the CC patients showed significantly higher prevalence of HOMA-IR, obesity indices, and various parameters of "lipotoxicity" and metabolic syndrome, suggesting that CC may be the long-term consequence of a type of "metabolic liver disease." Further studies are required to evaluate the role of therapeutic interventions to enhance insulin sensitivity in such patients.

    AIM: To evaluate the association between Chlamydia pneumoniae (Cpn) infection and primary biliary cirrhosis (PBC).METHODS: Cpn IgG and IgM were determined by enzymelinked immunosorbent assay (ELISA) in 41 well-established PBC patients and two race-matched control groups (posthepatitis cirrhosis, n = 70; healthy controls, n = 57).RESULTS: The mean level and seroprevalence of Cpn IgG in PBC group and post-hepatitis cirrhosis (PHC) group were significantly higher than those in healthy controls (46.8±43.4 RU/mL, 49.5±45.2 RU/mL vs28.3±32.7 RU/mL;68.3%, 71.4%, 42.1%, respectively; P<0.05). There was a remarkably elevated seroprevalence of Cpn IgM in patients with PBC (22.0%) compared to the PHC and healthy control (HC) groups. For the PBC patients versus the HCs, the odds ratios (ORs) of the presence of Cpn IgG and IgM were 2.7 (95% CI 0.9-6.1) and 5.1 (95% CI 1.4-18.5), respectively. Though there was no correlation in the level of Cpn IgG with total IgG in sera of patients with PBC (r = -0.857, P = 0.344>0.05), Cpn IgM was related with the abnormally high concentrations of total IgM in PBC group.CONCLUSION: The results of this study do not support the hypothesis that infection with Chlamydia pneumoniae may be a triggering agent or even a causative agent in PBC, but suggest that Chlamydia pneumoniae infection probably contributes to the high level of IgM present in most patients with PBC.

    Primary biliary cirrhosis (PBC) is a chronic cholestatic liver disease for which an autoimmune pathogenesis is supported by clinical and experimental data, including the presence of autoantibodies and autoreactive T cells. The etiology remains to be determined, yet data suggest that both a susceptible genetic background and unknown environmental factors determine disease onset. Multiple infectious and chemical candidates have been proposed to trigger the disease in a genetically susceptible host, mostly by molecular mimicry. Most recently, several murine models have been reported, including genetically determined models as well as models induced by immunization with xenobiotics and bacteria. PMID:20029462

    1985-03-01

    We describe the metabolism of purified human alpha 2-plasmin inhibitor in patients with liver cirrhosis to determine whether low plasma concentrations of alpha 2-plasmin inhibitor are the result of impaired synthesis or increased catabolism or both. A kinetic study was performed with 131I-alpha 2-plasmin inhibitor as a sensitive parameter of fibrinolysis in 14 patients with histologically proved liver cirrhosis compared with six healthy control subjects. Eight patients had macronodular cirrhosis (with positive hepatitis B surface antigen), and six had micronodular cirrhosis as a result of alcohol abuse. None of the patients had clinical signs of ascites, and in all the disease was stabilized. alpha 2-Plasmin inhibitor levels biologically and immunologically measured were decreased in all patients. Ten microCi 131I-alpha 2PI was injected intravenously, the disappearance of plasma radioactivity was measured, and turnover data were calculated according to the function x(t) = A1e-alpha 1t + A2e-alpha 2t + Be-beta t. Mean (+/- SD) turnover data in the control subjects were plasma radioactivity half-life 60.1 +/- 5.3 hours, fractional catabolic rate constant of the plasma pool 0.0318 +/- 0.0106 hr-1, and absolute catabolic (synthetic) rate constant 2.10 +/- 0.60 mg/kg/day. The alpha 1-phase was 1.26 +/- 0.23, and the transcapillary influx constant (k2,1) was 0.974 +/- 0.109 hr-1. In the patients, plasma radioactivity half-life was 58.7 +/- 12.09 hr, and fractional catabolic rate constant of the plasma pool 0.0283 +/- 0.0043 hr-1. The alpha 1-phase 4.74 +/- 6.48 and the transcapillary influx (k2,1) 3.08 +/- 3.9 hr-1 were both significantly increased compared with control values (p less than 0.05 and p less than 0.05, respectively.(ABSTRACT TRUNCATED AT 250 WORDS)

    2012-02-01

    Lack of medication compliance is harmful to health care systems from both a clinical and economic perspective. This study examines the methods that disease management organizations employ to identify nonadherent patients and to measure effectiveness of compliance programs for patients with diabetes, hyperlipidemia, and cystic fibrosis. In addition, this study investigates the degree to which disease managers assume risk in their contracts, and whether compliance strategies are being coordinated with payers' use of value-based insurance design, in which patient cost sharing is a function of the relative value of pharmaceuticals. This study's findings suggest that disease management may be falling short in terms of: (a) comprehensive commitment to expert-recommended at-home devices used to self-diagnose and measure health indicators; (b) early adoption of expert-recommended new technologies to measure and improve compliance; (c) intensity of use of standard tests in outpatient clinics; (d) coordination of compliance strategies with payers' use of value-based insurance design; and (e) the proportion of risk assumed in disease management contracts.

  12. Sarcopenia in the prognosis of cirrhosis: Going beyond the MELD score.

    Science.gov (United States)

    Kim, Hee Yeon; Jang, Jeong Won

    2015-07-01

    Estimating the prognosis of patients with cirrhosis remains challenging, because the natural history of cirrhosis varies according to the cause, presence of portal hypertension, liver synthetic function, and the reversibility of underlying disease. Conventional prognostic scoring systems, including the Child-Turcotte-Pugh score or model for end-stage liver diseases are widely used; however, revised models have been introduced to improve prognostic performance. Although sarcopenia is one of the most common complications related to survival of patients with cirrhosis, the newly proposed prognostic models lack a nutritional status evaluation of patients. This is reflected by the lack of an optimal index for sarcopenia in terms of objectivity, reproducibility, practicality, and prognostic performance, and of a consensus definition for sarcopenia in patients with cirrhosis in whom ascites and edema may interfere with body composition analysis. Quantifying skeletal muscle mass using cross-sectional abdominal imaging is a promising tool for assessing sarcopenia. As radiological imaging provides direct visualization of body composition, it is useful to evaluate sarcopenia in patients with cirrhosis whose body mass index, anthropometric measurements, or biochemical markers are inaccurate on a nutritional assessment. Sarcopenia defined by cross-sectional imaging-based muscular assessment is prevalent and predicts mortality in patients with cirrhosis. Sarcopenia alone or in combination with conventional prognostic systems shows promise for a cirrhosis prognosis. Including an objective assessment of sarcopenia with conventional scores to optimize the outcome prediction for patients with cirrhosis needs further research.

    Full Text Available Abstract Background Autogenous vein grafting is widely used in regular bypassing procedures. Due to its mismatch with the host artery in both mechanical property and geometry, the graft often over expands under high arterial blood pressure and forms a step-depth where eddy flow develops, thus causing restenosis, fibrous graft wall, etc. External stents, such as sheaths being used to cuff the graft, have been introduced to eliminate these mismatches and increase the patency. Although histological and immunochemical studies have shown some positive effects of the external stent, the mechanical mismatch under the protection of an external stent remains poorly analyzed. Methods In this study, the jugular veins taken from hypercholesterolemic rabbits were transplanted into the carotid arteries, and non-woven polyglycolic acid (PGA fabric was used to fabricate the external stents to study the effect of the biodegradable external stent. Eight weeks after the operation, the grafts were harvested to perform mechanical tests and histological examinations. An arc tangent function was suggested to describe the relationship between pressure and cross-sectional area to analyse the compliance of the graft. Results The results from the mechanical tests indicated that grafts either with or without external stents displayed large compliance in the low-pressure range and were almost inextensible in the high-pressure range. This was very different from the behavior of the arteries or veins in vivo. The data from histological tests showed that, with external stents, collagen fibers were more compact, whilst those in the graft without protection were looser and thicker. No elastic fiber was found in either kind of grafts. Furthermore, grafts without protection were over-expanded which resulted in much bigger cross-sectional areas. Conclusion The PGA external extent contributes little to the reduction of the mechanical mismatch between the graft and its host artery

    Background and aims: Anandamide is an endocannabinoid that evokes hypotension by interaction with peripheral cannabinoid CB1 receptors and with the perivascular transient receptor potential vanilloid type 1 protein (TRPV1). As anandamide has been implicated in the vasodilated state in advanced cirrhosis, the study investigated whether the mesenteric bed from cirrhotic rats has an altered and selective vasodilator response to anandamide. Methods: We assessed vascular sensitivity to anandamide, mRNA and protein expression of cannabinoid CB1 receptor and TRPV1 receptor, and the topographical distribution of cannabinoid CB1 receptors in resistance mesenteric arteries of cirrhotic and control rats. Results: Mesenteric vessels of cirrhotic animals displayed greater sensitivity to anandamide than control vessels. This vasodilator response was reverted by CB1 or TRPV1 receptor blockade, but not after endothelium denudation or nitric oxide inhibition. Anandamide had no effect on distal femoral arteries. CB1 and TRPV1 receptor protein was higher in cirrhotic than in control vessels. Neither CB1 mRNA nor protein was detected in femoral arteries. Immunochemistry showed that CB1 receptors were mainly in the adventitia and in the endothelial monolayer, with higher expression observed in vessels of cirrhotic rats than in controls. Conclusions: These results indicate that anandamide is a selective splanchnic vasodilator in cirrhosis which predominantly acts via interaction with two different types of receptors, CB1 and TRPV1 receptors, which are mainly located in perivascular sensory nerve terminals of the mesenteric resistance arteries of these animals.

    Full Text Available Serum and ascitic fluid superoxide dismutase (SOD and malondialdehyde (MDA levels were measured in 43 patients with cirrhosis and in a 10 healthy control group. Compensated cirrhotic patients had no clinically detectable ascites, but decompensated patients had massive ascites. Cirrhotic patients were divided into three groups: patients with compensated cirrhosis (n = 16, patients with decompensated cirrhosis with Spontaneous bacterial peritonitis (SBP (n = 14, and patients with decompensated cirrhosis without SBP (n = 13. All cirrhotic patients in the experimental group had significantly higher serum SOD (p 0.05. These results suggest that the increase in serum SOD and MDA levels are not related to the presence of SBP and the status of liver cirrhosis. To sum up, clarifying the impact of increased serum SOD and MDA levels in cirrhotic patients needs further investigation.

    Rosmarinus officinalis (Lamiaceae) possesses antioxidant activity and hepatoprotective effects, and so may provide a possible therapeutic alternative for chronic liver disease. The effect produced by a methanolic extract of Rosmarinus officinalis on CCl(4)-induced liver cirrhosis in rats was investigated using both prevention and reversion models. Over the course of the development of cirrhosis, the increased enzymatic activities of gamma-glutamyl transpeptidase and alanine aminotransferase, and the rise in bilirubin levels caused by CCl(4) administration, were prevented by Rosmarinus officinalis co-administration. When the cirrhosis by oxidative stress was evaluated as an increase on liver lipoperoxidation, total lipid peroxides, nitric oxide in serum, and loss of erythrocyte plasma membrane stability, R. officinalis was shown to prevent such alterations. On cirrhotic animals treated with CCl(4), histological studies showed massive necrosis, periportal inflammation and fibrosis which were modified by R. officinalis. These benefits on experimental cirrhosis suggest a potential therapeutic use for R. officinalis as an alternative for liver cirrhosis.

    Compared to lower limb arterial diseases, upper limb arterial diseases look rare, heterogeneous with various etiologies and a rather vague clinical picture, but with a negligible risk of amputation. Almost all types of arterial diseases can be present in the upper limb, but the anatomical and hemodynamic conditions particular to the upper limb often confuse the issue. Thus, atherosclerosis affects mainly the subclavian artery in its proximal segment where the potential of collateral pathway is high making the symptomatic forms not very frequent whereas the prevalence of subclavian artery stenosis or occlusion is relatively high. The clinical examination and the etiologies are discussed according to the clinical, anatomical and hemodynamic context.

  8. Corporate compliance and voluntary disclosure.

    In any event, the decision to institute a corporate compliance program is a relatively simple one. In view of the ambiguity surrounding certain fraud and abuse provisions, and the corporate "death sentence" that may result from program exclusion, a compliance program is always sound corporate policy. To be sure, if the compliance program is administered improperly, it can actually increase the likelihood of whistleblower actions and create a body of potentially hurtful documentation. But these dangers can be minimized by structuring the program to protect the self-evaluative process through relevant privileges. The risks also pale in comparison to the exposure to criminal or exclusionary sanctions when improper conduct goes undetected by an organization.

    The current study demonstrated that injury of the spinal cord lateral funiculus occurs in liver cirrhosis. This study sought to compare the morphology of the thoracic and lumbar cord, the expression of functional proteins, and changes in vessels between liver cirrhosis and non-cirrhosis corpses. Results showed that in the liver cirrhosis group, the hepatic vein expanded, the gastrointestinal tract was full of coagulated blood, blood-stasis was easily seen in the veniplex of the vertebral canal and the lumbar spinal cord, and the cell bodies of the anterior horn in the thoracic and lumbar cord were smaller than those in non-cirrhosis corpses. In addition, nerve cells shrank, Nissl bodies were concentrated with obscured nuclei, and neurofilament and synapsin containing cell bodies of the anterior horn and white matter decreased in the liver cirrhosis group. These experimental findings indicate that abnormal circulation of the spinal cord, resulting from hemodynamic change of cirrhotic portal hypertension, may be the most significant cause of hepatic myelopathy.

    2010-06-01

    Surveys on tax compliance and non-compliance often rely on ad hoc formulated items which lack standardization and empirical validation. We present an inventory to assess tax compliance and distinguish between different forms of compliance and non-compliance: voluntary versus enforced compliance, tax avoidance, and tax evasion. First, items to measure voluntary and enforced compliance, avoidance, and evasion were drawn up (collected from past research and newly developed), and tested empirically with the aim of producing four validated scales with a clear factorial structure. Second, findings from the first analyses were replicated and extended to validation on the basis of motivational postures. A standardized inventory is provided which can be used in surveys in order to collect data which are comparable across research focusing on self-reports. The inventory can be used in either of two ways: either in its entirety, or by applying the single scales independently, allowing an economical and fast assessment of different facets of tax compliance.

    1995-01-01

    This study explored the feasibility and safety of percutaneous coronary balloon angioplasty (PTCA) with miniaturized PTCA equipment via the radial artery. Coronary angioplasty (PTCA) via the femoral or brachial arteries may be associated with rare vascular complications such as bleeding and damage to the artery and adjacent structures. It was postulated that PTCA via the radial artery with miniaturized angioplasty equipment is feasible and that no major puncture site-related complications occur because hemostasis is obtained easily and because no major structures are near the radial artery. With double blood supply to the hand, radial artery occlusion is well tolerated. In 100 patients with collateral blood supply to the right hand, PTCA was attempted with 6F guiding catheters and rapid-exchange balloon catheters for exertional angina (87 patients) or nonexertional angina (13 patients). Angioplasty was attempted in 122 lesions (type A n = 67 [55%], Type B n = 37 [30%], and type C n = 18 [15%]). Pre- and post-PTCA computerized quantitative coronary analysis was performed. Radial artery function and structure were assessed clinically and with Doppler and two-dimensional ultrasound on the day of discharge. Coronary catheterization via the radial artery was successful in 94 patients (94%). The 6 remaining patients had successful PTCA via the femoral artery (n = 5) or the brachial artery (n = 1). Procedural success (120 of 122 lesions) was achieved in 92 patients (98%) via the radial artery and in 98 patients of the total study population.(ABSTRACT TRUNCATED AT 250 WORDS)

    Full Text Available Background/Aim: Thrombocytopenia is a common finding in patients with cirrhosis and may lead to unnecessary referral for bone marrow (BM biopsy. To date, the prevalence of cirrhosis in patients with thrombocytopenia who receive BM biopsy is largely unknown. Materials and Methods: Between fiscal years 2006-2010, 744 patients (≥18 years who underwent BM biopsies for thrombocytopenia at our hospital were identified retrospectively. 541 patients were excluded who had hematologic malignancies and received chemotherapy. Remaining 203 patients with predominant isolated thrombocytopenia were included in the study. Results: Of 203 patients, 136 (67% had a normal and 67 (33% had an abnormal BM examination. Prevalence of cirrhosis in the study population was 35% (95% CI: 28.4-41.9. 51% patients with normal BM were found to have cirrhosis compared to 3% of patients with abnormal BM exam (P < 0.0001. Common causes of cirrhosis were nonalcoholic steatohepatitis (NASH (47%, followed by alcohol and Hepatitis C virus infection. Idiopathic thrombocytopenia and myelodysplastic syndrome were most frequent causes of thrombocytopenia in patients without cirrhosis. Patients with NASH had higher body mass index (BMI (33.4 vs. 25.8, P < 0.001 and lower MELD scores (11.1 vs. 16, P = 0.028 when compared to non-NASH patients with cirrhosis. Conclusion: Approximately, one third (35% of patients with cirrhosis induced thrombocytopenia may undergo unwarranted BM biopsies. Clinical diagnosis of cirrhosis is still a challenge for many physicians, particularly with underlying NASH. We propose cirrhosis to be the prime cause of isolated thrombocytopenia.

    Full Text Available Compliance mismatch between stent graft and host artery may induce complications and blood flow disorders. However, few studies have been reported on stent graft compliance. This study aims to explore the deformation and compliance of stent graft in stented and unstented zones under three pressure ranges. Compliance of two stent grafts incorporated with polyurethane graft (nitinol-PU and polyester graft (nitinol-PET materials respectively were tested; the stents used in the two stent grafts were identical. For the circumferential deformation of the stent grafts under each pressure range, the nitinol-PET stent graft was uniform in both zones. The nitinol-PU stent graft was circumferentially uniform in the stented zone, however, it was nonuniform in the unstented zone. The compliance of the PU graft material was 15 times higher than that of the PET graft. No significant difference in compliance was observed between stented and unstented zones of the nitinol-PET stent graft regardless of the applied pressure range. However, for the nitinol-PU stent graft, compliance of the unstented PU region was approximately twice that of the stented region; thus, compliance along the length of the nitinol-PU stent graft was not constant and different from that of the nitinol-PET stent graft.

    Cialdini, Robert B; Goldstein, Noah J

    2004-01-01

    This review covers recent developments in the social influence literature, focusing primarily on compliance and conformity research published between 1997 and 2002. The principles and processes underlying a target's susceptibility to outside influences are considered in light of three goals fundamental to rewarding human functioning. Specifically, targets are motivated to form accurate perceptions of reality and react accordingly, to develop and preserve meaningful social relationships, and to maintain a favorable self-concept. Consistent with the current movement in compliance and conformity research, this review emphasizes the ways in which these goals interact with external forces to engender social influence processes that are subtle, indirect, and outside of awareness.

    We propose a new, simple way of constructing elastic tubes which can be used to model the nonlinear elastic properties of large arteries. The tube models are constructed from a silicon elastomer (Sylgard 184, Dow Corning), which exhibits a nonlinear behavior with increased stiffness at high strains. Tests conducted on different tube models showed that, with the proper choice of geometric parameters, the elastic properties, in terms of area-pressure relation and compliance, can be similar to that of real arteries.

    This article deals with the effect of Fuzheng Huayu recipe (FZHYR), composed of Semen Persicae, Cordyceps, Radix Salviae Miltiorrhizae, Pollen pini, etc. in treating posthepatitic cirrhosis. 40 patients treated with FZHYR were observed, and another 40 patients in simila condition treated with symptomatic therapy were taken as control. Results showed that the FZHYR could (1) Increase the serum level of albumin and decrease the gamma-globulin; (2) Elevate the lowered plasma branched-chain amino acid/aromatic amino acid ratio; (3) Reduce the raised level of laminin and hyaluronic acid in serum; (4) Escalate the level of CD3+, CD4+, CD4+/CD8+ ratio, NK cells activity and complement C3, lowered the raised level of IgG and IgM in serum. In addition, it could also adjust the anormal change of hormonal secretion. These results suggested that FZHYR has beneficial effect in treating posthepatitic cirrhosis, it acts multifariously and plays important role either in controlling the development of disease or in preventing the complications.

    2014-07-01

    Portal vein thrombosis in cirrhosis is a relatively common complication associated with the presence of an accompanying prothrombotic phenotype of advanced cirrhosis. The consequences of portal vein thrombosis are relevant because it can be associated with impaired hepatic function, might contraindicate hepatic transplantation and could increase morbidity in the surgical procedure. There is controversy concerning the most effective treatment of portal vein thrombosis, which is based on information that is seldom robust and whose primary objective is to achieve a return to vessel patency. Various studies have suggested that starting anticoagulation therapy early is associated with portal vein repatency more frequently than without treatment and has a low rate of complications. There are no proven data on the type of anticoagulant (low-molecular-weight heparins or dicoumarin agents) and the treatment duration. The implementation of TIPS is technically feasible in thrombosis without cavernous transformation and is associated with portal vein recanalization in a significant proportion of cases. Thrombolytic therapy does not appear to present an adequate balance between efficacy and safety; its use is therefore not supported for this indication. The proper definition of treatment for portal vein thrombosis requires properly designed studies to delimit the efficacy and safety of the various alternatives.

    Spontaneous bacterial peritonitis is a well-known complication of cirrhosis; however, spontaneous fungal peritonitis (SFP) is less well-recognised and described. Our objective was to determine the clinical characteristics, treatment outcomes and factors associated with death among patients with SFP. We performed a retrospective cohort study using the primary outcome of all-cause mortality at 28 days. Twenty-five patients were included; Candida species were the causative pathogen in all cases. At the onset of SFP, patients were critically ill, median APACHE II and MELD scores were 22 and 30.3, respectively. The 28-day mortality rate was 56%; six patients died prior to culture positivity. Among the remaining patients, there were no differences in rates of death by treatment regimen (P = 0.55). APACHE II score at the onset of SFP was an independent predictor of death (OR = 1.46, 95% CI = 1.02-2.08, P = 0.04). In conclusion, SFP develops among critically ill patients with cirrhosis and is associated with high rates of death. Directed antifungal therapy did not improve patient outcomes. Future studies assessing the benefit of early or pre-emptive antifungal therapy are warranted.

    1984-06-01

    Full Text Available Resistant ascites was studied in 34 patients with liver cirrhosis and ascites. The patients were initially divided into 3 groups on the basis of the weekly cumulative ascites retention curve: patients relieved of ascites within 3 weeks of admission, patients relieved between 4 and 12 weeks and patients with ascites persisting beyond 13 weeks. "Resistant ascites" was defined as "ascites persisting for more than 13 weeks after admission to the hospital". The patients were then reclassified into 3 groups : Group A being those patients relieved of ascites within 12 weeks, Group B being those with resistant ascites and group C being those who died within 12 weeks of admission. There were no differences in age and sex distribution, etiology of liver cirrhosis, past medical history or physical findings among the 3 groups. However, Group B had higher levels of serum creatinine and blood urea nitrogen than Group A on admission. Serum bilirubin was higher and serum albumin was lower in Group C than in Group B, which indicates that Group C had greater liver cell failure.

    Perlík, F

    2013-07-01

    Metabolic liver functions are significantly involved in the total clearance of a number of drugs. In liver cirrhosis the reduced drug elimination is a result of the blood flow through the liver, hepatocytes function and volume of hepatic tissue. Pharmacokinetic and pharmacodynamic changes depend on the nature and degree of hepatic impairment and on the characteristics of the dosed drug. Hepatocytes have a different extraction ability with respect to the individual drugs. The following are examples of drugs with high hepatic extraction: anodyne, propranolol, metoprolol, verapamil and lidocaine. These drugs are significantly dependent on the first passage through the liver. Intrahepatic and extrahepatic collateral blood flows significantly increase their bio-logical availability and reduce the clearance. The reduction in hepatic clearance of drugs with low extraction coefficient, such as chlordiazepoxide, diazepam or furosemide, is a result of its own limited functional capacity to eliminate the drug. Predicting a hepatic metabolic disorder based on a common bio-chemical assessment of enzyme activities is not sufficient. In advanced liver cirrhosis a higher risk is demonstrated for drugs with a narrow therapeutic width. It is always necessary to take into account whether the pharmacotherapy is necessary, use small doses and cautiously monitor the patient.

    Ascites is one of the major complications of liver cirrhosis and is associated with a poor prognosis. It is important to distinguish noncirrhotic from cirrhotic causes of ascites to guide therapy in patients with noncirrhotic ascites. Mild to moderate ascites is treated by salt restriction and diuretic therapy. The diuretic of choice is spironolactone. A combination treatment with furosemide might be necessary in patients who do not respond to spironolactone alone. Tense ascites is treated by paracentesis, followed by albumin infusion and diuretic therapy. Treatment options for refractory ascites include repeated paracentesis and transjugular intrahepatic portosystemic shunt placement in patients with a preserved liver function. Potential complications of ascites are spontaneous bacterial peritonitis (SBP) and hepatorenal syndrome (HRS). SBP is diagnosed by an ascitic neutrophil count > 250 cells/mm3 and is treated with antibiotics. Patients who survive a first episode of SBP or with a low protein concentration in the ascitic fluid require an antibiotic prophylaxis. The prognosis of untreated HRS type 1 is grave. Treatment consists of a combination of terlipressin and albumin. Hemodialysis might serve in selected patients as a bridging therapy to liver transplantation. Liver transplantation should be considered in all patients with ascites and liver cirrhosis.

    Cirrhotic cardiomyopathy is a condition recently known in liver cirrhosis consisting of systolic dysfunction to stress factors, diastolic dysfunction and electrophysiological abnormalities in the absence of cardiac disease. The prevalence of cirrhotic cardiomyopathy remains unknown until now. It can be diagnosed by using a combination of electrocardiograph, 2-dimensional echocardiography, and various serum markers (brain natriuretic factor--BNP, proBNP, TnI). Pathogenic mechanisms underlying cirrhotic cardiomyopathy development include abnormal signaling betaadrenergic, cardiomyocites membrane fluidity changes, interstitial fibrosis, myocardial hypertrophy, altered transmembrane ion channels as intervention with negative inotropic effect of different substances whose concentration is increased in cirrhosis. Major stresses on the cardiovasculary system such as liver transplantations, infections, insertion of transjugular portosystemic stent-shunt (TIPSS) have been demonstrated to put in evidence the presence of cirrhotic cardiomyopathy. Heart failure is a significant cause of mortality after liver transplantation but the improvement of liver function determines cardiac abnormalities reversal. Current management recommendations include empirical, nonspecific and mainly supportive measures, no specific treatment can be recommended, and cardiac failure should be treated as in non-cirrhotic patients with sodium restriction, diuretics, and oxygen therapy when necessary. The exact prognosis remains unclear. The extent of cirrhotic cardiomyopathy generally correlates to the degree of liver insufficiency. Reversibility is possible (either pharmacological or after liver transplantation), but further studies are needed.

  3. Immunopathogenesis of primary biliary cirrhosis: an old wives' tale

    Directory of Open Access Journals (Sweden)

    Smyk Daniel S

    2011-12-01

    Full Text Available Abstract Primary biliary cirrhosis (PBC is a cholestatic liver disease characterised by the autoimmune destruction of the small intrahepatic bile ducts. The disease has an unpredictable clinical course, but may progress to fibrosis and cirrhosis. Although medical treatment with urseodeoxycholic acid is largely successful, some patients may progress to liver failure requiring liver transplantation. PBC is characterised by the presence of disease specific anti-mitochondrial (AMA antibodies, which are pathognomonic for PBC development. The disease demonstrates an overwhelming female preponderance and virtually all women with PBC present in middle age. The reasons for this are unknown; however several environmental and immunological factors may be involved. As the immune systems ages, it become less self tolerant, and mounts a weaker response to pathogens, possibly leading to cross reactivity or molecular mimicry. Some individuals display immunological changes which encourage the development of autoimmune disease. Risk factors implicated in PBC include recurrent urinary tract infection in females, as well as an increased prevalence of reproductive complications. These risk factors may work in concert with and possibly even accelerate, immune system ageing, contributing to PBC development. This review will examine the changes that occur in the immune system with ageing, paying particular attention to those changes which contribute to the development of autoimmune disease with increasing age. The review also discusses risk factors which may account for the increased female predominance of PBC, such as recurrent UTI and oestrogens.

    AIM: To evaluate the potential of laparoscopy in the diagnosis of cirrhosis and outcome of interferon treatment in HCV-infected patients.METHODS: In this retrospective study, diagnostic laparoscopy with laparoscopic liver biopsy was performed in 72 consecutive patients with chronic HCV infection. The presence or absence of cirrhosis was analyzed macroscopically by laparoscopy and microscopically by liver biopsy specimens. Clinical and laboratory data and outcome of interferon-alfa treatment were compared between cirrhotic and noncirrhotic patients.RESULTS: Laparoscopically, cirrhosis was seen in 29.2%(21/72) and non-cirrhosis in 70.8% (51/72) of patients.Cirrhotic patients were significantly older with a significant longer duration of HCV infection than noncirrhotic patients.Laboratory parameters (AST, y-GT, y-globulin fraction) were measured significantly higher as well as significantly lower (prothrombin index, platelet count) in cirrhotic patients than in non-cirrhotic patients. Histologically, cirrhosis was confirmed in 11.1% (8/72) and non cirrhosis in 88.9% (64/72). Patients with macroscopically confirmed cirrhosis (n=21) showed histologically cirrhosis in 38.1% (8/21) and histologically noncirrhosis in 61.9% (13/21). In contrast, patients with macroscopically non-cirrhosis (n=51) showed histologically non cirrhosis in all cases (51/51). Thirty-nine of 72 patients were treated with interferon-alfa, resulting in 35.9% (14/39)patients with sustained response and 64.1% (25/39) with non response. Non-responders showed significantly more macroscopically cirrhosis than sustained responders. In contrast, there were no significant histological differences between non-responders and sustained responders.CONCLUSION: Diagnostic laparoscopy is more accurate than liver biopsy in recognizing cirrhosis in patients with chronic HCV infection. Liver biopsy is the best way to assess inflammatory grade and fibrotic stage. The invasive marker for staging, prognosis and

Arterial stiffness (AS can be determined by measurement of arterial pulse wave velocity (APWV. Separate from any role as a surrogate marker, AS is an important determinant of pulse pressure, left ventricular function and coronary artery perfusion pressure. Proximal elastic arteries and peripheral muscular arteries respond differently to aging and to medication. Endogenous human growth hormone (hGH, secreted by the anterior pituitary, peaks during early adulthood, declining at 14% per decade. Levels of insulin-like growth factor-I (IGF-I are at their peak during late adolescence and decline throughout adulthood, mirror imaging GH. Arterial endothelial dysfunction, an accepted cause of increased APWV in GH deficiency (GHD is reversed by recombinant human (rh GH therapy, favorably influencing the risk for atherogenesis. APWV is a noninvasive method for measuring atherosclerotic and hypertensive vascular changes increases with age and atherosclerosis leading to increased systolic blood pressure and increased left ventricular hypertrophy. Aerobic exercise training increases arterial compliance and reduces systolic blood pressure. Whole body arterial compliance is lowered in strength-trained individuals. Homocysteine and C-reactive protein are two infl ammatory markers directly linked with arterial endothelial dysfunction. Reviews of GH in the somatopause have not been favorable and side effects of treatment have marred its use except in classical GHD. Is it possible that we should be assessing the combined effects of therapy with rhGH and rh

    The subscapular artery arises from the third part of the axillary artery and gives off the circumflex scapular and the thoracodorsal arteries. Although anatomical variations of the axillary artery are very common, the existence of a unilateral accessory thoracodorsal artery has been described in the literature only once. There are no reports of bilateral accessory thoracodorsal artery, in the literature. In the present study, a bilateral accessory thoracodorsal artery, originating on either side of the third part of the axillary artery, is described in a 68-year-old female cadaver. All the other branches of the axillary artery had a typical origin, course, distribution and termination. This extremely rare anatomical variation apart from the anatomical importance also has clinical significance for surgeons in this area. Especially, during the dissection or mobilization of the latissimus dorsi that is partly used for coverage problems in many regions of the body and also in dynamic cardiomyoplasty, any iatrogenic injury of this accessory artery may result in ischemia and functional loss of the graft.

  19. ETHICS AND COMPLIANCE IN BUSINESS

    Directory of Open Access Journals (Sweden)

    2015-05-01

    Full Text Available In this paper, we have studied the evolution of the business ethics concept through the prism of definitions from some renowned authors in the field and through the approach model of the business ethics and by implementing it in the company level. We have found out that in the last 40 years this concept has evolved from a theoretical aspect, as well as a practical one. Companies are motivated to implement ethics and compliance programs in business so that they can manage the changes that come from society. If, until recently, all that mattered for a company was profit, in the last decades, the situation changed. In order to develop a durable business, it is essential to have a good reputation. Owning and implementing an ethics and compliance program in business has become an imperative for companies, regardless of their activity sector. The role of the compliance department becomes more pregnant in each company: the employees need safety, the existence of communication lines provides comfort. From the partners in business’ point of view, owning such a program is a necessity, a condition, and not conforming to the principles of business ethics can lead to the isolation of the company. The ethics and compliance programs in business are instruments that protect the company by implementing certain proactive identification mechanisms that ensure the development of an ethical organizational culture.

    Arterial hypertension is the most common chronic disease in developed countries and it is the leading risk factor for stroke, ischemic heart disease, congestive heart failure, chronic renal failure and peripheral artery disease. Its prevalence appears to be about 30-45% of the general population. Recent European guidelines estimate that up to 15-20% of the hypertensive patients are not controlled on a dual antihypertensive combination and they require three or more different antihypertensive drug classes to achieve adequate blood pressure control. The guidelines confirmed that diuretics, beta-blockers, calcium-channel blockers, angiotensin-converting enzyme inhibitors and angiotensin receptor blockers are suitable for the initiation and maintenance of antihypertensive treatment, either as monotherapy or in combination therapy. Very few antihypertensive agents have reached the market over the last few years, but no new therapeutic class has really emerged. The long-term adherence to cardiovascular drugs is still low in both primary and secondary prevention of cardiovascular diseases. In particular, the issue of compliance is persistently high in hypertension, despite the fixed-dose combination therapy. As a consequence, a cohort of high-risk hypertensive population, represented by patients affected by refractory and resistant hypertension, can be identified. Therefore, the need of controlling BP in high-risk patients may be addressed, in part, by the development of new drugs, devices and procedures that are designed to treat hypertension and comorbidities. In this review we will comprehensively discuss the current literature on recent therapeutic advances in hypertension, including both medical therapy and interventional procedures.

    A 69-year-old male with a history of hepatitis B-induced cirrhosis underwent segmental liver resection for hepatocellular carcinoma. At his 12-month follow-up, local recurrence in segment VII was diagnosed, measuring 7.8 by 6.2 cm, with irregular margins and the presence of a tumor thrombus in the portal vein. After evaluation by the multidisciplinary liver team, the patient underwent transcatheter arterial chemoembolization with drug-eluting beads. Forty-eight hours after his discharge, the patient presented with gangrenous cholecystitis and he underwent an uneventful cholecystectomy. Cholecystitis is a well-documented complication of transcatheter arterial chemoembolization due to inadvertent reflux of the embolic material into the cystic artery. However, super selective embolization significantly reduces the risk of cholecystitis. In most cases, management is conservative and only severe cases require further intervention.

  7. Corporate compliance: framework and implementation.

    Science.gov (United States)

    Fowler, N

    1999-01-01

    The federal government has created numerous programs to combat fraud and abuse. The government now encourages healthcare facilities to have a corporate compliance program (CCP), a plan that reduces the chances that the facility will violate laws or regulations. A CCP is an organization-wide program comprised of a code of conduct and written policies, internal monitoring and auditing standards, employee training, feedback mechanisms and other features, all designed to prevent and detect violations of governmental laws, regulations and policies. It is a system or method ensuring that employees understand and will comply with laws that apply to what they do every day. Seven factors, based on federal sentencing guidelines, provide the framework for developing a CCP. First, a facility must establish rules that are reasonably capable of reducing criminal conduct. Second, high-level personnel must oversee the compliance effort. Third, a facility must use due care in delegating authority in the compliance initiative. Fourth, standards must be communicated effectively to employees, and fifth, a facility must take reasonable steps to achieve compliance. Sixth, standards must be enforced consistently across the organization and last, standards must be modified or changed for reported concerns, to ensure they are not repeated. PROMINA Health System, Inc. in Atlanta, Ga., designed a program to meet federal guidelines. It started with a self-assessment to define its areas or risk. Next, it created the internal structure and assigned organizational responsibility for running the CCP. PROMINA then developed standards of business and professional conduct, established vehicles of communication and trained employees on the standards. Finally, it continues to develop evidence of the program's effectiveness by monitoring and documenting its compliance activities.

    Intestinal barrier dysfunction, facilitating translocation of bacteria and bacterial products, plays an important role in the pathophysiology of liver cirrhosis and its complications. Increased intestinal permeability has been found in patients with liver cirrhosis, but data on small and large intestine permeability and tight junctions (TJs) in patients with compensated cirrhosis are scarce. We aimed to investigate both small and large intestine permeability in patients with stable compensated cirrhosis compared with healthy controls and evaluated the expression of TJ proteins in mucosal biopsies at duodenal and sigmoid level. Intestinal permeability was assessed in 26 patients with compensated cirrhosis and 27 matched controls using a multisugar test. Duodenal and sigmoid biopsies were available from a subgroup for analyses of gene transcription and expression of key TJ proteins by qRT-PCR and ELISA, respectively. Median 0-5-h urinary sucrose excretion and lactulose/rhamnose ratio were comparable between patients with compensated cirrhosis and controls, whereas 5-24-h urinary sucralose/erythritol ratio was increased in these patients. Downregulation of gene transcription was found for claudin-3 in duodenal biopsies and claudin-4 in sigmoid biopsies, and at the protein level occludin expression was significantly increased in both duodenal and sigmoid biopsies. This study shows that gastroduodenal and small intestine permeability are not altered, whereas large intestine permeability is increased in patients with stable compensated cirrhosis. Only limited alterations were found regarding the expression of TJ proteins in both the small and large intestine.

    BACKGROUND:This study was designed to probe the clinical value in assessing the degree of liver cirrhosis by using the arrival time of contrast agent in the right portal vein in contrast-enhanced ultrasonography, as well as the velocity and lfow volume in the right portal vein using the color Doppler velocity proifle technique. METHODS:Twenty-eight patients with HBV post-hepatic cirrhosis were grouped into compensated (13 patients) and decompensated cirrhosis (15); 30 patients without hepatic cirrhosis served as controls. Written informed consent was obtained from each patient. All the patients with hepatic cirrhosis were pathologically conifrmed by percutaneous biopsy. SonoVue was injected to detect the arrival time in the right portal vein. The velocity and lfow volume in the right portal vein were measured. The value of each parameter was compared for correlation analysis. RESULTS: The arrival time in the right portal vein in the cirrhosis group was much longer than that in the control group (24.92±1.34 vs. 20.81±0.55 sec, respectively, P CONCLUSIONS:With the development of liver cirrhosis, the arrival time of contrast agent in the right portal vein is gradually prolonged, whereas the velocity and lfow volume in this vein decreases markedly, and there is a negative correlation between the results of the two methods.

    AIM: To study the outcomes of patients with compensated hepatitis C virus-related cirrhosis.METHODS: Twenty-four grade A5 and 11 grade A6 of Child-Pugh classification cirrhotic patients with active virus replication, treated for a mean period of 31.3 ±5.1 mo with moderate doses of interferon-alpha and ribavirin, were compared to a cohort of 36 patients with similar characteristics, without antiviral treatment.Salivary caffeine concentration, a liver test of microsomal function, was determined at the starting and thrice in course of therapy after a mean period of 11 ± 1.6 mo,meanwhile the resistive index of splenic artery at ultra sound Doppler, an indirect index of portal hypertension,was only measured at the beginning and the end of study.RESULTS: Eight out of the 24 A5- (33.3%) and 5 out of the 11 A6- (45.45%) treated-cirrhotic patients showed a significant improvement in the total overnight salivary caffeine assessment. A reduction up to 20% of the resistive index of splenic artery was obtained in 3 out of the 8 A5- (37.5%) and in 2 out of the 5 A6- (40%)cirrhotic patients with an improved liver function, which showed a clear tendency to decrease at the end of therapy. The hepatitis C virus clearance was achieved in 3 out of the 24 (12.5%) A5- and 1 out of the 11 (0.091%) A6-patients after a median period of 8.5 mo combined therapy. In the cohort of non-treated cirrhotic patients, not only the considered parameters remained unchanged, but 3 patients (8.3%) had a worsening of the Child-Pugh score (P = 0.001).CONCLUSION: A prolonged antiviral therapy with moderate dosages of interferon-alpha and ribavirin shows a trend to stable liver function or to ameliorate the residual liver function, the entity of portal hypertension and the compensation status at acceptable costs.

    Full Text Available Splenectomy in patients with cirrhosis presupposes an increase of blood inflow into portal system to decrease the portal pressure. At the same time there are different opinions about splenectomy. So it is actual to study the character of changes of blood flow in vessels of abdominal cavity in pre- and postsurgical periods and assessment of an influence of these changes on the clinical course of cirrhosis.Aim of research: To assess an influence of splenectomy on the character of changes of splanchnic hemodynamics in patients with cirrhosis comparing to non-operated patients with compensated and decompensated clinical course.Materials and methods: There were examined 190 patients with cirrhosis: gastrointestinal bleeding from oesophagus varicose veins took place in 133 patients, diuretic resistant ascites – in 57 ones. 19 patients underwent splenectomy: 7 – in association with sewing of the left gastric vein and artery, 6 – with “skeletonization” of the lesser curvature of stomach with Nessen’s operation, 2 – with Patsiora’s operation, 2 – with application of selective porto-caval shunt between the low mesenteric vein and the left vein of an ovary. 84 patients died during observation. The duration of observation was from 0.5 to 3.5 years. All patients underwent fibrogastroscopy every 3–4 month. Hemodynamics was assessed on the base of repeated ultrasound of abdominal cavity. There were assessed diameter of hepatic and splenic vessels; qualitative and quantitative characteristics of blood flow in hepatic and splenic arteries, portal and splenic veins.Results of research: Changes of hemodynamics in patients after splenectomy as opposed to non-operative patients are characterized with the decrease of diameter of portal vein at almost stable speed of the linear blood flow in it. The result is some decrease of the volume of portal blood and index of portal blood congestion that indirectly indicates the decrease of portal pressure

    AIM: To build up the research models of hepatic fibrosis in mice.METHODS: Inbred wild-type FVB/N mice were either treated with alpha-naphthyl-isothiocyanate (ANIT), allyl alcohol (AA),carbon tetrachloride (CCl4), 3,5-diethoxycarbonyl-1,4-dihydrocollidine (DDC), and silica, or subjected to common bile duct ligation (CBDL) to induce hepatic injury. Liver biopsies were performed every 4 wk to evaluate hepatic fibrosis over a period of 6 mo. Cumulative cirrhosis and survival curves were constructed by life table method and compared with Wilcoxon test.RESULTS: Under the dosages used, there was neither mortality nor cirrhosis in AA and silica-treated groups. DDC and ANIT caused cirrhosis within 4-12 and 12-24 wk, respectively.Both showed significantly faster cirrhosis induction at high dosages without significant alteration of survival. The duration for cirrhosis induction by CCl4 ranged from 4 to 20 wk, mainly dependent upon the dosage. However, the increase in CCl4dosage significantly worsened survival. Intraperitoneal CCl4administration resulted in better survival in comparison with gavage administration at high dosage, but not at medium and low dosages. After CBDL, all the mice developed liver cirrhosis within 4-8 wk and then died by the end of 16 wk.CONCLUSION: CBDL and administrations of ANIT, CCl4, and DDC ensured liver cirrhosis. CBDL required the least amount of time in cirrhosis induction, but caused shortened lives of mice. It was followed by DDC and ANIT administration with favorable survival. As for CCl4, the speed of cirrhosis induction and the mouse survival depended upon the dosages and the administration route.

    The authors studied structural-and-functional properties of the arterial wall, also assessing elastic properties of the common femoral artery and the brachial artery flow-dependent dilatation (FDD) index in a total of thirty-six patients presenting with nonspecific aortoarteritis (NAA). The overwhelming majority of the patients, i. e., twenty-four (89%), showed a statistically significant decrease in the FDD as compared with the control-group patients (P<0.05). We revealed a statistically reliable (P=0.0005) inverse correlation between the level of systolic arterial pressure and an increase in the rigidity index of the common femoral artery wall. Also determined was a correlation of the femoral artery wall rigidity (systolic AP equalling 140 mm Hg and higher) and the brachial artery flow-dependent dilatation index (r=-0.61). All the patients suffering from non-specific aortoarteritis were diagnosed as having a decrease in the elasticity values, accompanied by an increase in systolic arterial pressure (r=0.36; P=0.07). Comparing the level of systolic arterial pressure with the values of the distensibility coefficient and compliance coefficient revealed a weak inverse correlation (r=-0.28 and 0.21, respectively). Evaluating the impact of duration of the disease on the distensibility coefficient, compliance coefficient and the rigidity index made it possible to detect a statistically significant (P=0.0039) direct correlation between the rigidity index and the duration of non-specific aortoarteritis. To a leaser degree, the duration of the inflammatory process influenced the distensibility coefficient and compliance coefficient (r=-0.28; r=-0.30, respectively; P=0.06).

    The goal of this study was to evaluate the effect of vascular compliance, resistance, and pulse rate on the resistive index (RI) by using an electrical circuit model to simulate renal blood flow. In order to analyze the renal arterial Doppler waveform, we modeled the renal blood-flow circuit with an equivalent simple electrical circuit containing resistance, inductance, and capacitance. The relationships among the impedance, resistance, and compliance of the circuit were derived from well-known equations, including Kirchhoff’s current law for alternating current circuits. Simulated velocity-time profiles for pulsatile flow were generated using Mathematica (Wolfram Research) and the influence of resistance, compliance, and pulse rate on waveforms and the RI was evaluated. Resistance and compliance were found to alter the waveforms independently. The impedance of the circuit increased with increasing proximal compliance, proximal resistance, and distal resistance. The impedance decreased with increasing distal compliance. The RI of the circuit decreased with increasing proximal compliance and resistance. The RI increased with increasing distal compliance and resistance. No positive correlation between impedance and the RI was found. Pulse rate was found to be an extrinsic factor that also influenced the RI. This simulation study using an electrical circuit model led to a better understanding of the renal arterial Doppler waveform and the RI, which may be useful for interpreting Doppler findings in various clinical settings.

  18. Arterial waveform analysis.

    Esper, Stephen A; Pinsky, Michael R

    2014-12-01

    The bedside measurement of continuous arterial pressure values from waveform analysis has been routinely available via indwelling arterial catheterization for >50 years. Invasive blood pressure monitoring has been utilized in critically ill patients, in both the operating room and critical care units, to facilitate rapid diagnoses of cardiovascular insufficiency and monitor response to treatments aimed at correcting abnormalities before the consequences of either hypo- or hypertension are seen. Minimally invasive techniques to estimate cardiac output (CO) have gained increased appeal. This has led to the increased interest in arterial waveform analysis to provide this important information, as it is measured continuously in many operating rooms and intensive care units. Arterial waveform analysis also allows for the calculation of many so-called derived parameters intrinsically created by this pulse pressure profile. These include estimates of left ventricular stroke volume (SV), CO, vascular resistance, and during positive-pressure breathing, SV variation, and pulse pressure variation. This article focuses on the principles of arterial waveform analysis and their determinants, components of the arterial system, and arterial pulse contour. It will also address the advantage of measuring real-time CO by the arterial waveform and the benefits to measuring SV variation. Arterial waveform analysis has gained a large interest in the overall assessment and management of the critically ill and those at a risk of hemodynamic deterioration.

    Hepatitis B and C are rare in Sri Lanka. Nonalcoholic fatty liver disease is increasing in the country. Eighty-one patients referred for liver transplantation (LT) over a period of 18 months were prospectively evaluated. Ninety-two percent (n = 74) were males. Cryptogenic cirrhosis was the leading indication for LT (58%, n = 47) followed by alcohol in 27% (n = 33). Hepatitis B and C were not seen in our cases. The liver biochemistry and clinical status of cirrhosis were similar in cryptogenic and alcoholic cirrhotics. Fourteen patients died while waiting for transplant, and nine transplants were performed. Cryptogenic cirrhosis is the leading cause for LT in Sri Lanka.

    Environmental baseline documents and NEPA compliance guides should be carried in every NEPA implementation ``tool kit``. These two indispensable tools can play a major role in avoiding repeated violations of NEPA requirements that have occurred over the past 26 years. This paper describes these tools, discusses their contents, and explains how they are used to prepare better NEPA documents more cost-effectively. Focus is on experience at Sandia Laboratories (NM).

    Primary biliary cirrhosis (PBC) is characterized by the autoimmune injury of small intrahepatic bile duct. On this basis, it has been suggested that the targeted biliary epithelial cells (BEC) play an active role in the perpetuation of autoimmunity by attracting immune cells via chemokine secretion. To address this issue, we challenged BEC using multiple toll-like receptor (TLR) ligands as well as autologous liver infiltrating mononuclear cells (LMNC) with subsequent measurement of BEC phenotype and chemokine production and LMNC chemotaxis by quantifying specific chemokines, specially CX3CL1 (fractalkine). We submit the hypothesis that BEC are in fact the innocent victims of the autoimmune injury and that the adaptive immune response is critical in PBC. PMID:22235377

    2005-01-01

    Full Text Available An increased prevalence of X chromosome monosomy has recently been demonstrated in patients with primary biliary cirrhosis (PBC. Chronic cholestasis of unknown etiology is a common clinical feature in patients with Turner syndrome who reach the fourth and fifth decades of life. A 37-year-old patient with Turner syndrome who presented with clinical and biochemical features of chronic cholestasis is described. Subsequent investigations confirmed the diagnosis of PBC. The patient did not respond to the medical treatment and was referred for liver transplant assessment. The present case may support the importance of X chromosome genes in the development of genetic predisposition to PBC, and emphasizes the necessity for a systematic study of the prevalence of PBC in patients with Turner syndrome.

  6. Prevention and Management of Bacterial Infections in Cirrhosis

    2011-01-01

    Full Text Available Patients with cirrhosis of liver are at risk of developing serious bacterial infections due to altered immune defenses. Despite the widespread use of broad spectrum antibiotics, bacterial infection is responsible for up to a quarter of the deaths of patients with liver disease. Cirrhotic patients with gastrointestinal bleed have a considerably higher incidence of bacterial infections particularly spontaneous bacterial peritonitis. High index of suspicion is required to identify infections at an early stage in the absence of classical signs and symptoms. Energetic use of antibacterial treatment and supportive care has decreased the morbidity and mortality over the years; however, use of antibiotics has to be judicious, as their indiscriminate use can lead to antibiotic resistance with potentially disastrous consequences. Preventive strategies are still in evolution and involve use of antibiotic prophylaxis in patients with gastrointestinal bleeding and spontaneous bacterial infections and selective decontamination of the gut and oropharynx.

  7. Primary Biliary Cirrhosis Is a Generalized Autoimmune Epithelitis

    Directory of Open Access Journals (Sweden)

    2015-03-01

    Full Text Available Primary biliary cirrhosis (PBC is a chronic progressive autoimmune cholestatic liver disease characterized by highly specific antimitochondrial antibodies (AMAs and the specific immune-mediated injury of small intrahepatic bile ducts. Unique apoptotic feature of biliary epithelial cells (BECs may contribute to apotope presentation to the immune system, causing unique tissue damage in PBC. Perpetuation of inflammation may result in senescence of BECs, contributing to irreversible loss of bile duct. In addition to the classic liver manifestations, focal inflammation and tissue damage are also seen in salivary glands and urinary tract in a significant proportion of PBC patients. These findings provide potent support to the idea that molecular mimicry may be involved in the breakdown of autoimmune tolerance and mucosal immunity may lead to a systematic epithelitis in PBC patients. Thus, PBC is considered a generalized epithelitis in clinical practice.

    Full Text Available A 45-year-old female was diagnosed with Hashimoto’s thyroiditis in 1976 and Addison’s disease in 1979. At that time, her antimitochondrial antibody (AMA level was elevated at 1:32. She subsequently developed premature ovarian failure and type I diabetes mellitus. In 1996, she became jaundiced with a cholestatic enzyme pattern. AMA was positive at a titre of 1:256. A liver biopsy confirmed the diagnosis of primary biliary cirrhosis (PBC. She underwent a liver transplantation in January 1998. This is the first report of PBC in association with type II autoimmune polyglandular syndrome. The association of PBC with other organ-specific autoimmune diseases supports an immune-mediated pathogenesis and may have implications in further studies of PBC.

    We report a patient with chronic inflammatory demyelinating polyneuropathy associated with primary biliary cirrhosis (PBC). Except for minimal biochemical abnormalities, clinical symptoms of PBC were not observed, and we diagnosed our patient with asymptomatic PBC from the results of a liver biopsy. Although the patient noticed little muscle weakness, an electrophysiological study demonstrated slow conduction velocities and prolonged distal latencies, with definite conduction blocks in the median, ulnar, and tibial nerves. The disturbed sensory pattern was asymmetrical, and sensory nerve action potentials were not evoked. From these observations, we diagnosed this patient with chronic inflammatory demyelinating polyneuropathy. Neuropathy associated with PBC is very rare. We must differentiate demyelinating neuropathy with PBC in patients with asymmetrical sensory dominant neuropathy with high immunoglobulin M titers, and investigate for the presence of anti-mitochondrial antibodies to rule out a complication of asymptomatic PBC.

    Objectives: The purpose of this study was to compare mean liver T{sub 1ρ} values in patients with liver cirrhosis and healthy control subjects in order to evaluate T{sub 1ρ} as a potential MR biomarker for liver cirrhosis. Materials and methods: Ten healthy control subjects (mean age 42.7 years; 6 female, 4 male) and 21 patients with clinically diagnosed liver cirrhosis (mean age 56.5 years; 5 female, 16 male) were examined at 1.5 T (Magnetom Avanto, Siemens). T{sub 1ρ}-weighted images were acquired using a 2D TurboFLASH sequence (TR/TE 3/1.31 ms, FA 8°, FoV 309 × 380 mm, resolution 2 × 2 × 6 mm, acquisition time 15 s, slice thickness 6 mm) with spin-lock preparation. T{sub 1ρ} maps were calculated from five breath-hold measurements, performed with different spin-lock times (4, 8, 16, 32 and 48 ms). Mean liver T{sub 1ρ} values of healthy control subjects and patients with liver cirrhosis were calculated and compared using Student t-test. In addition, a receiver operating characteristic (ROC) curve analysis was performed to evaluate the utility of mean liver T{sub 1ρ} values for the prediction of liver cirrhosis. Results: Mean liver T{sub 1ρ} values in patients with liver cirrhosis (57.4 ± 7.4 ms) were significantly higher than those of healthy subjects (47.8 ± 4.2 ms; p = 0.0007). According to the ROC analysis at a threshold value of 50.1 ms the sensitivity and specificity of mean liver T{sub 1ρ} in predicting liver cirrhosis were 90.5% and 90%, respectively. The area under the ROC curve was 0.90. Conclusion: Mean liver T{sub 1ρ} values in patients with liver cirrhosis were significantly higher than those in healthy subjects suggesting a potential role of liver T{sub 1ρ} as a MR biomarker for liver cirrhosis.

    Full Text Available Introduction. Aim of this study is to determine if HbA1c levels are a reliable predictor of glycemic control in patients with decompensated cirrhosis. Methods. 200 unique patients referred for liver transplantation at University of Tennessee/Methodist University Transplant Institute with a HbA1c result were included. Three glucose levels prior to the “measured” A1c (MA1c were input into an HbA1c calculator from the American Diabetes Association website to determine the “calculated” A1c (CA1c. The differences between MA1c and CA1c levels were computed. Patients were divided into three groups: group A, difference of 1.5. Results. 97 (49% patients had hemoglobin A1c of less than 5%. Discordance between calculated and measured HbA1c of >0.5% was seen in 47% (n=94. Higher level of discordance of greater than >1.5 was in 12% of patients (n=24. Hemoglobin was an independent predictor for higher discordance (odds ratio 0.77 95%, CI 0.60–0.99, and p value 0.04. HbA1c was an independent predictor of occurrence of HCC (OR 2.69 955, CI 1.38–5.43, and p value 0.008. Conclusion. HbA1c is not a reliable predictor of glycemic control in patients with decompensated cirrhosis, especially in those with severe anemia.

    AIM: (1) To compare the prevalence of osteoporosis (t-score ≤-2.5 SD) between stage Ⅳ PBC patients, and two groups of age- and sex-matched controls: one with hepatitis C virus (HCV)-related cirrhosis, and the other one consisting of a group of healthy subjects from the general population; (2) to identify the main risk factors for the development of bone loss.METHODS: Thirty-five stage Ⅳ PBC patients (mean age 52.5±10 years), 49 females with HCV-related cirrhosis (mean age 52.9±5.8 years) and 33 healthy females (mean age 51.8+2.22 years) were enrolled in the study. Bone metabolism was evaluated by measuring serum calcium corrected for serum albumin (Ca corr.), 25-hydroxy vitamin D (25-OH vit D), parathyroid hormone, osteocalcin.Bone mineral density (BMD) was assessed at the lumbar spine by dual-photon X-ray absorptiometry.RESULTS: Osteoporosis was present in 5/35 PBC patients (14.2%) and in 7/49 HCV-related cirrhotic patients (14.3%),without any statistical difference between the two groups.Among healthy control subjects, none had osteoporosis.No difference was found between the three groups in serum parameters of bone metabolism. Univariate analysis showed that menopausal state and low BMI were significantly correlated with osteoporosis. Multivariate regression analysis showed that menopausal status, BMI <23, and old age were independent variables significantly correlated with osteoporosis.CONCLUSION: PBC in itself has no negative influence on BMD. End-stage liver disease patients carry a disease-specific risk for osteoporosis, but have an effective risk of bone loss in relation to individual potential risk for each patient. A practical message should be taken into account, that is, every effort should be made to prevent osteoporosis when a patient has simple osteopenia, or if it is a woman in or near menopausal age.

  16. Stability of cirrhotic systemic hemodynamics ensures sufficient splanchnic blood flow after living-donor liver transplantation in adult recipients with liver cirrhosis

    Institute of Scientific and Technical Information of China (English)

    2007-01-01

    AIM: To investigate the correlation between systemic hemodynamics and splanchnic circulation in recipients with cirrhosis undergoing living-donor liver transplantation (LDLT), and to clarify how systemic hemodynamics impact on local graft circulation after LDLT.METHODS: Systemic hemodynamics, indocyanine green (ICG) elimination rate (KICG) and splanchnic circulation were simultaneously and non-invasively investigated by pulse dye densitometry (PDD) and ultrasound. Accurate estimators of optimal systemic hyperdynamics after LDLT [i.e., balance of cardiac output (CO) to blood volume (BV) and mean transit time (MTT), defined as the time required for half the administered ICG to pass through an attached PDD sensor in the first circulation] were also measured. Thirty recipients with cirrhosis were divided into two groups based on clinical outcomes corresponding to postoperative qraft function.RESULTS: Cirrhotic systemic hyperdynamics characterized by high CO, expanded BV and low total peripheral resistance (TPR) were observed before LDLT. TPR reflecting cirrhotic vascular alterations was slowly restored after LDLT in both groups. Although no significant temporal differences in TPR were detected between the two groups, CO/BV and MTT differed significantly. Recipients with good outcomes showed persistent cirrhotic systemic hyperdynamics after LDLT, whereas recipients with poor outcomes presented with unstable cirrhotic systemic hyperdynamics and severely decreased KICG. Systemic hyperdynamic disorders after LDLT impacted on portal venous flow but not hepatic arterial flow.CONCLUSION: We conclude that subtle systemic hyperdynamics disorders impact on splanchnic circulation, and that an imbalance between CO and BV decreases portal venous flow, which results in critical outcomes.

    2016-01-01

    A coronary artery fistula (CAF) is an abnormal communication between a coronary artery and a cardiac chamber or a great vessel. CAFs are rare based on coronary arteriography and when found they most often empty into the right ventricle and atrium and less often into the high pressure, low compliance left ventricle (LV). A patient who presented with atypical chest pain and was found to have multiple small CAFs originating from the ramus intermedius coronary artery and emptying into the LV is presented. This case highlights the challenges in providing an appropriate therapy for multiple small CAFs emptying into the LV. PMID:27525009

    Background Non-invasive assessment of arterial pressure wave forms using applanation tonometry of the radial or carotid arteries can be technically challenging and has not found wide clinical application. 2D imaging of the common carotid arteries is routinely used and we sought to determine whether arterial waveform measurements could be derived from tissue Doppler imaging (TDI) of the carotid artery. Methods We studied 91 subjects (52 men, age 52 ± 14 years) with and without cardiovascular disease. Tonometry was performed on the carotid artery simultaneously with pulsed wave Doppler of the LVOT and acquired digitally. Longitudinal 2D images of the common carotid artery with and without TDI were also acquired digitally and both TDI and tonometry were calibrated using mean and diastolic cuff pressure and analysed off line. Results Correlation between central pressure by TDI and tonometry was excellent for maximum pressure (r = 0.97, p < 0.0001). The mean differences between central pressures derived by TDI and tonometry were minimal (systolic 5.36 ± 5.5 mmHg; diastolic 1.2 ± 1.2 mmHg). Conclusion Imaging of the common carotid artery motion with tissue Doppler may permit acquisition of a waveform analogous to that from tonometry. This method may simplify estimation of central arterial pressure and calculation of total arterial compliance. PMID:17266772
