Abstract
BACKGROUND It is necessity to work more on non-invasive markers like right liver lobe size/albumin concentration ratio for predicting esophageal varices. We aimed to see the right liver lobe/albumin ratio in identifying esophageal varices among patients with cirrhosis caused by hepatitis B and C. METHODS A cross-sectional study was conducted among all indoor patients admitted to the Department of Internal Medicine, Pakistan Atomic Energy Commission, General Hospital, Sector H-11/4 Islamabad, Pakistan, during May-December 2016. A non-probability purposive sampling technique was used for data collection. Diagnosed cases of cirrhosis caused by hepatitis B and C virus infection aged 25 years or more were included. A pre-designed questionnaire was used for data collection. Statistical analysis was done using SPSS software version 20. RESULTS A total number of 160 patients were included. Mean ± SD age was 56.04 ± 10.22 years, while 96 (60%) were men. Child-Turcotte-Pugh grades showed 41.88% of the patients with grade A, followed by grade B (38.12%), and grade C (20%). Esophageal varices were observed in 76.25% of the patients. The sensitivity was 86.89%, while specificity was 78.95%. The positive predictive value was 92.98% (95% confidence interval [CI] = 86.64% - 96.91%) and negative predictive value was 65.22% (CI = 49.75% - 78.64%) with a diagnostic accuracy of 85%. CONCLUSION The use of the studied non-invasive markers of portal hypertension particularly the right liver lobe size/albumin concentration ratio, can help physicians to restrict the use of endoscopic screening only to patients presenting a high probability of esophageal varices.

Abstract
Background: Liver fibrosis is a chronic liver disease associated with an excessive accumulation of extracellualr matrix (ECM) proteins which ultimately lead to cirrohosis and hepatocellular carcinoma. Purpose: Liver fibrosis therapies that use combination approaches with the ability to affect multiple disease pathways have proven higher efficacies. This study aimed at optimizing and characterizing the co-encapsulation of pirfenidone (PF) and AMD3100 (AMD) into CXCR4-targeted combination liposomes (CTC liposome) for CXCR4 targeting, and the inhibition of major molecular culprits ie α-SMA, CXCR4, TGFβ, and P-p38 involved in liver fibrosis in-vitro. Methods: The CTC liposomes were prepared using the thin-film hydration method. The concentration of encapsulated AMD and PF was measured by HPLC and UV spectrophotometry, respectively. Tramsmission electron microscopy (TEM) was used to determine the liposomal morphology. The CXCR4 targeting ability was determined by CXCR4 redistribution assay. Confocal microscopy and flowcytometry were used to determine the CXCR4 mediated cell uptake. The apoptosis inducing and protein downreguating ability of CTC liposomes were determined by apoptosis assay and western blot analysis, respectively. In-vivo biodistribution and Hoechst staining were used to confirm the feasibility of CTC liposome for the in-vivo applications and drug targeted accumulation, respectively. Results: The TEM studies revealed that CTC liposomes were spherical in shape. The cumulative release of AMD and PF from CTC liposome was 67% and 84%, respectively, at 48 h. Compared to the free drug counterparts, encapsulated drugs displayed higher cell viability. The CXCR4 redistribution assay confirmed the CXCR4 targeting and antagonistic ability of CTC liposomes. The CTC liposomes were internalized more effectively via caveolae-mediated endocytic pathways. CTC liposomes displayed aggressive apoptosis (87.3%) in TGFβ-induced activated HSC-T6 cells suggesting a propensity to fibrosis regression. Also, CTC liposomes significantly reduced α-SMA (65%), CXCR4 (77%), TGFβ (89%), and P-p38 (66%) expressions, better than free drugs. CTC@IR780 liposomes (CTC liposomes incorporating IR780 dye) were more accumulated in fibrotic livers compared to free IR780, as judged by in-vivo imaging, biodistribution analysis, and Hoechst staining. These findings suggest that this simple and stable CTC liposomal system holds a great promise for the treatment and prevention of liver fibrosis.

Abstract
OBJECTIVE To evaluate quality of life, religiosity and anxiety and depressive symptoms in liver transplant candidates. METHOD An epidemiological and cross-sectional study carried out with liver transplant candidates attended at the outpatient clinic of a University Hospital from 2014 to 2016. RESULTS Fifty (50) patients with a mean age of 52.5 years old participated in the study, predominantly male (58.0%), having access to primary education (48.0%), Model for End-Stage Liver Disease between 10-19 and having viral hepatitis as the main etiology. They presented an average quality of life score (4.1), high intrinsic religiosity index (5.6) and the presence of anxiety (52.0%) and depressive symptoms (48.0%). It was possible to observe an association between religiosity and quality of life in the worry domain, with higher non-organizational religiosity leading to higher quality of life; anxiety and depressive symptoms were not associated with quality of life and religiosity. However, patients with higher levels of education were more likely to present depressive symptoms. CONCLUSION The analysis of quality of life and religiosity was significant, reinforcing the need for the care team to consider religiosity as a coping strategy for the disease.

Abstract
BACKGROUND Hepatic encephalopathy is a common and devastating neuropsychiatric complication of acute liver failure or chronic liver disease. Ammonia content in the blood seems to play a role in the development of hepatic encephalopathy. Treatment for hepatic encephalopathy is complex. Acetyl-L-carnitine is a substance that may reduce ammonia toxicity. This review assessed the benefits and harms of acetyl-L-carnitine for patients with hepatic encephalopathy. OBJECTIVES To assess the benefits and harms of acetyl-L-carnitine for patients with hepatic encephalopathy. SEARCH METHODS We searched the Cochrane Hepato-Biliary Group Controlled Trials Register, CENTRAL, MEDLINE Ovid, Embase Ovid, LILACS, and Science Citation Index Expanded for randomised clinical trials. We sought additional randomised clinical trials from the World Health Organization Clinical Trials Search Portal and ClinicalTrials.gov. We performed all electronic searches until 10 September 2018. We looked through the reference lists of retrieved publications and review articles, and we searched the FDA and EMA websites. SELECTION CRITERIA We searched for randomised clinical trials in any setting, recruiting people with hepatic encephalopathy. Trials were eligible for inclusion if they compared acetyl-L-carnitine plus standard care (e.g. antibiotics, lactulose) versus placebo or no acetyl-L-carnitine plus standard care. We are well aware that by selecting randomised clinical trials, we placed greater focus on potential benefits than on potential harms. DATA COLLECTION AND ANALYSIS We selected randomised clinical trials, assessed risk of bias in eight domains, and extracted data in a duplicate and independent fashion. We estimated risk ratios (RRs) for dichotomous outcomes and mean differences (MDs) for continuous outcomes. We measured statistical heterogeneity using I² and D² statistics. We subjected our analyses to fixed-effect and random-effects model meta-analyses. We assessed bias risk domains to control systematic errors. We assessed overall quality of the data for each individual outcome by using the GRADE approach. MAIN RESULTS We identified five randomised clinical trials involving 398 participants. All trials included only participants with cirrhosis as the underlying cause of hepatic encephalopathy. Trials included participants with covert or overt hepatic encephalopathy. All trials were conducted in Italy by a single team and assessed acetyl-L-carnitine compared with placebo. Oral intervention was the most frequent route of administration. All trials were at high risk of bias and were underpowered. None of the trials were sponsored by the pharmaceutical industry.None of the identified trials reported information on all-cause mortality, serious adverse events, or days of hospitalisation. Only one trial assessed quality of life using the Short Form (SF)-36 scale (67 participants; very low-quality evidence). The effects of acetyl-L-carnitine compared with placebo on general health at 90 days are uncertain (MD -6.20 points, 95% confidence interval (CI) -9.51 to -2.89). Results for additional domains of the SF-36 are also uncertain. One trial assessed fatigue using the Wessely and Powell test (121 participants; very low-quality evidence). The effects are uncertain in people with moderate-grade hepatic encephalopathy (mental fatigue: MD 0.40 points, 95% CI -0.21 to 1.01; physical fatigue: MD -0.20 points, 95% CI -0.92 to 0.52) and mild-grade hepatic encephalopathy (mental fatigue: -0.80 points, 95% CI -1.48 to -0.12; physical fatigue: 0.20 points, 95% CI -0.72 to 1.12). Meta-analysis showed a reduction in blood ammonium levels favouring acetyl-L-carnitine versus placebo (MD -13.06 mg/dL, 95% CI -17.24 to -8.99; 387 participants; 5 trials; very low-quality evidence). It is unclear whether acetyl-L-carnitine versus placebo increases the risk of non-serious adverse events (8/126 (6.34%) vs 3/120 (2.50%); RR 2.51, 95% CI 0.68 to 9.22; 2 trials; very low-quality evidence). Overall, adverse events data were poorly reported and harms may have been underestimated. AUTHORS' CONCLUSIONS This Cochrane systematic review analysed a heterogeneous group of five trials at high risk of bias and with high risk of random errors conducted by only one research team. We assessed acetyl-L-carnitine versus placebo in participants with cirrhosis with covert or overt hepatic encephalopathy. Hence, we have no data on the drug for hepatic encephalopathy in acute liver failure. We found no information about all-cause mortality, serious adverse events, or days of hospitalisation. We found no clear differences in effect between acetyl-L-carnitine and placebo regarding quality of life, fatigue, and non-serious adverse events. Acetyl-L-carnitine reduces blood ammonium levels compared with placebo. We rated all evidence as of very low quality due to pitfalls in design and execution, inconsistency, small sample sizes, and very few events. The harms profile for acetyl-L-carnitine is presently unclear. Accordingly, we need further randomised clinical trials to assess acetyl-L-carnitine versus placebo conducted according to the SPIRIT statements and reported according to the CONSORT statements.

Abstract
AIM In this study, we aimed to evaluate the effectiveness of an educational intervention in patients with liver cirrhosis. BACKGROUND Liver cirrhosis is end stage of liver diseases with many complications that affects quality of life and nutritional status in cirrhotic patients. Today, educational intervention and nutritional counseling is a key factor for preventing disease process and improving quality of life in patients with chronic diseases. METHODS This quasi-experimental, non-randomized, pre and post intervention were conducted as a pilot study on cirrhotic patients. Educational intervention and nutritional counseling were performed in clinical visits and via guide booklet. Chronic liver disease questionnaire (CLDQ) and knowledge questionnaire were used to assess patients' quality of life and knowledge. Blood samples were taken before and after intervention for assessment of laboratory outcomes. RESULTS One hundred and seven patients referred to Research Center for enrolling in the trial. Twenty-eight did not meet inclusion criteria and seven patients were excluded from the study for lack of proper follow-up. Final analyses were done on 72 patients. Quality of life and knowledge of cirrhotic patients improved significantly after educational intervention (P < 0.0001). Biochemical characteristics were not changed significantly. Ascites and edema were improved significantly (P = 0.005 and P = 0.002, respectively). There was significant difference before and after intervention in the days of hospitalization (P = 0.001). CONCLUSION We concluded a simple educational intervention and continuous monitoring for 6 months can affect clinical outcomes, quality of life, hospital admissions days, and knowledge of patients with cirrhosis.

Unsolved Issues in the Treatment of Spontaneous Peritonitis in Patients with Cirrhosis: Nosocomial Versus Community-acquired Infections and the Role of Fungi. Rev Recent Clin Trials 2019; 14:129-135. [PMID: 30514194 DOI: 10.2174/1574887114666181204102516] [Citation(s) in RCA: 5] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/10/2018] [Revised: 11/26/2018] [Accepted: 11/27/2018] [Indexed: 06/09/2023]
Abstract
INTRODUCTION Historically, spontaneous bacterial peritonitis (SBP) has represented one of the most frequent and relevant infectious complications of advanced liver disease, and this is still valid today. Nevertheless, in recent years the role of fungi as causative pathogens of primary peritonitis in patients with cirrhosis has become not negligible. Another issue is linked with the traditional distinction, instrumental in therapeutic choice, between community-acquired and nosocomial forms, according to the onset. Between these two categories, another one has been introduced: the so-called "healthcare-associated infections". OBJECTIVE To discuss the most controversial aspects in the management of SBP nowadays in the light of best available evidence. METHODS A review of recent literature through MEDLINE was performed. RESULTS The difference between community-acquired and nosocomial infections is crucial to guide empiric antibiotic therapy, since the site of acquisition impact on the likelihood of multidrug-resistant bacteria as causative agents. Therefore, third-generation cephalosporins cannot be considered the mainstay of treatment in each episode. Furthermore, the distinction between healthcare-associated and nosocomial form seems very subtle, especially in areas wherein antimicrobial resistance is widespread, warranting broad-spectrum antibiotic regimens for both. Finally, spontaneous fungal peritonitis is a not common but actually underestimated entity, linked to high mortality. Especially in patients with septic shock and/or failure of an aggressive antibiotic regimen, the empiric addition of an antifungal agent might be considered. CONCLUSION Spontaneous bacterial peritonitis is one of the most important complications in patients with cirrhosis. A proper empiric therapy is crucial to have a positive outcome. In this respect, a careful assessment of risk factors for multidrug-resistant pathogens is crucial. Likewise important, mostly in nosocomial cases, is not to overlook the probability of a fungal ascitic infection, namely a spontaneous fungal peritonitis.

Abstract
We propose that the circulatory impairments produced, in both portal hypertension and liver cirrhosis, to a certain degree resemble those characterizing prenatal life in the fetus. In fact, the left-right circulatory syndrome is common in cirrhotic patients and in the fetus. Thus, in patients with portal hypertension and chronic liver failure, the re-expression of a blood circulation comparable to fetal circulation is associated with the development of similar amniotic functions, i.e., ascites production and placenta functions, and portal vascular enteropathy. Therefore, these re-expressed embryonic functions are extra-embryonic and responsible for prenatal trophism and development.

Abstract
BACKGROUND Endovascular aneurysm repair (EVAR) and thoracic endovascular aortic repair (TEVAR) are effective and minimally invasive treatments for high-risk surgical candidates. However, information about the management of EVAR and TEVAR in liver cirrhosis (LC) is lacking. The aim of our study was to evaluate outcomes after EVAR and TEVAR in patients with LC. METHODS Using Taiwan's National Health Insurance Research Database, we retrospectively evaluated patients who underwent EVAR and TEVAR therapy between January 1, 2006, and December 31, 2013. RESULTS A total of 146 patients with LC and 730 matched patients without LC were eligible for analysis after propensity score matching. In-hospital mortality and perioperative complications were not statistically significantly different between the two cohorts, although the LC group had an increased volume of blood transfusion and a trend toward a lower survival rate (P of stratified Cox = .092). However, patients with LC had a higher adjusted hazard ratio for death (1.66; 95% confidence interval, 1.31-2.12; P < .001) in the sensitivity analysis by traditional multivariable adjustment. The LC cohort had a higher risk of liver-related death (4.1% vs 0.7%; P = .001) and liver-related readmission (6.2% vs 0.3%; P < .001). As expected, the advanced LC group had a higher mortality rate than the early LC group (P = .022). The risk for reintervention, redo open aortic surgery (P = .859), and redo stent graft therapy (P = .179) was not statistically significantly different between the two cohorts. CONCLUSIONS Short-term results after EVAR and TEVAR are promising in patients with LC, despite poor long-term outcomes, because of the nature of LC. Innovations in endovascular therapy for aortic disease have improved surgical outcomes, even in high-risk patients with LC.

Abstract
BACKGROUND The assessment of symptoms distress is an important strategy for symptoms management and treatment of patients with liver cirrhosis (LC); however, appropriate instruments are limited. OBJECTIVE The objective of this study was to validate a symptoms distress scale (SDS) by confirming the appropriateness of each item using item response theory. METHODS A cross-sectional and convenience sampling was conducted to recruit eligible cirrhotic outpatients from the gastroenterology outpatient department of a single medical university hospital. In total, 163 patients with LC completed the 21-item SDS. A graded response model with two-parameter (discrimination and difficulty) estimation was used for data analysis. RESULTS The item response theory model identified the validity of the SDS and found that most of the items in the SDS represented a high level of symptoms distress; moreover, three items of bruising, drowsiness, and dark urine were reported in cirrhotic patients with severe symptom distress. Four items comprising bodily pain, right upper quadrant pain, muscle cramps, and change in appearance can be appropriately represented in cirrhotic patients with mild symptoms distress. Moreover, the amount of test information in the SDS was >0.70, indicating acceptable reliability. DISCUSSION Items of the SDS can be useful for assessing different levels of symptoms distress; however, using the scale to assess mild symptoms distress in populations with LC should be done with great caution.

Abstract
Obesity and metabolic syndrome are considered as responsible for a condition known as the non-alcoholic fatty liver disease that goes from simple accumulation of triglycerides to hepatic inflammation and may progress to cirrhosis. Patients with obesity also have an increased risk of primary liver malignancies and increased body mass index is a predictor of decompensation of liver cirrhosis. Sarcopenic obesity confers a risk of physical impairment and disability that is significantly higher than the risk induced by each of the two conditions alone as it has been shown to be an independent risk factor for chronic liver disease in patients with obesity and a prognostic negative marker for the evolution of liver cirrhosis and the results of liver transplantation. Cirrhotic patients with obesity are at high risk for depletion of various fat-soluble, water-soluble vitamins and trace elements and should be supplemented appropriately. Diet, physical activity and protein intake should be carefully monitored in these fragile patients according to recent recommendations. Bariatric surgery is sporadically used in patients with morbid obesity and cirrhosis also in the setting of liver transplantation. The risk of sarcopenia, micronutrient status, and the recommended supplementation in patients with obesity and cirrhosis are discussed in this review. Furthermore, the indications and contraindications of bariatric surgery-induced weight loss in the cirrhotic patient with obesity are discussed.

Abstract
With the ever increasing global obesity pandemic, clinical burden from obesity related complications are anticipated in parallel. Bariatric surgery, a treatment approved for weight loss in morbidly obese patients, has reported to be associated with good outcomes, such as reversal of type two diabetes mellitus and reducing all-cause mortality on a long term basis. However, complications from bariatric surgery have similarly been reported. In particular, with the onslaught of non-alcoholic fatty liver disease (NAFLD) epidemic, in associated with obesity and metabolic syndrome, there is increasing prevalence of NAFLD related liver cirrhosis, which potentially connotes more risk of specific complications for surgery. Bariatric surgeons may encounter, either expectedly or unexpectedly, patients with non-alcoholic steatohepatitis (NASH) and NASH related cirrhosis more frequently. As such, the issues and considerations surrounding their medical care/surgery warrant careful deliberation to ensure the best outcomes. These considerations include severity of cirrhosis, liver synthetic function, portal hypertension and the impact of surgical factors. This review explores these considerations comprehensively and emphasizes the best approach to managing cirrhotic patients in the context of bariatric surgery.

World J Hepatol 2018; 10:425-432. [PMID: 29988878 PMCID: PMC6033715 DOI: 10.4254/wjh.v10.i6.425] [Citation(s) in RCA: 11] [Impact Index Per Article: 1.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 12/22/2018] [Revised: 03/13/2018] [Accepted: 04/11/2018] [Indexed: 02/06/2023] Open
Abstract
AIM To determine the readmission rate, its reasons, predictors, and cost of 30-d readmission in patients with cirrhosis and ascites. METHODS A retrospective analysis of the nationwide readmission database (NRD) was performed during the calendar year 2013. All adults cirrhotics with a diagnosis of ascites, spontaneous bacterial peritonitis, or hepatic encephalopathy were identified by ICD-9 codes. Multivariate analysis was performed to assess predictors of 30-d readmission and cost of readmission. RESULTS Of the 59597 patients included in this study, 18319 (31%) were readmitted within 30 d. Majority (58%) of readmissions were for liver related reasons. Paracentesis was performed in 29832 (50%) patients on index admission. Independent predictors of 30-d readmission included age < 40 (OR: 1.39; CI: 1.19-1.64), age 40-64 (OR: 1.19; CI: 1.09-1.30), Medicaid (OR: 1.21; CI: 1.04-1.41) and Medicare coverage (OR: 1.13; CI: 1.02-1.26), > 3 Elixhauser comorbidity (OR: 1.13; CI: 1.05-1.22), nonalcoholic cirrhosis (OR: 1.16; CI: 1.10-1.23), paracentesis on index admission (OR: 1.28; CI: 1.21-1.36) and having hepatocellular carcinoma (OR: 1.21; CI: 1.05; 1.39). Cost of index admission was similar in patients readmitted and not readmitted (P-value: 0.34); however cost of care was significantly more on 30 d readmission ($30959 ± 762) as compared to index admission ($12403 ± 378), P-value: < 0.001. CONCLUSION Cirrhotic patients with ascites have a 33% chance of readmission within 30-d. Younger patients, with public insurance, nonalcoholic cirrhosis and increased comorbidity who underwent paracentesis are at increased risk of readmission. Risk factors for unplanned readmission should be targeted given these patients have higher healthcare utilization.

Abstract
Acute variceal bleeding is one of the most fatal complications of cirrhosis and is responsible for about one-third of cirrhosis-related deaths. Therefore, every effort should be made to emergently resuscitate the patients, start pharmacotherapy as soon as possible and do endoscopic therapy in a timely manner. Despite the recent advances in treatment, mortality rate is still high. We provide a comprehensive review of evaluation and management of variceal bleeding.

Abstract
BACKGROUND Cirrhosis of liver is a pathological condition, wherein functions of liver are impaired by chronic liver exploitations. Due to decrease in synthetic capacity, expressions of plasma proteins tend to decrease in blood stream. Serpins (Serine protease inhibitors) are class of plasma proteins expressed from liver with structural similarities and diverse functions. SERPINA4 (Kallistatin) is a multifunctional serpin clade A protein expressed from liver and concentration in serum is the reflection of extent of liver dysfunction. OBJECTIVE To identify interference of other serpins by immunological cross reactivity with SERPINA4 in cirrhotic liver and healthy subjects. MATERIALS AND METHODS Blood samples were collected from 20 subjects (10 cirrhotic liver, 10 healthy) from R.L. Jalappa Hospital and Research Centre, Kolar, Karnataka, India. Separation of proteins was carried out by SDS-PAGE. Cross reactivity study was analyzed using western blot. RESULTS Proteins present in cirrhotic liver and healthy subject's serum were separated by SDS PAGE. There was no band detection on both (cirrhotic liver and healthy) PVDF (polyvinylidene diflouride) membranes. However, a significant band was observed with recombinant kallistatin. CONCLUSION Structurally similar serpins with minor amino acid sequence similarities did not show any immunological cross reactivity with SERPINA4 due to non identical epitope in cirrhotic liver and healthy subjects. Present study revealed that there is no interference of serpins for immunological reactions in quantitative estimation of kallistatin which needs further validation.

Abstract
BACKGROUND & AIMS Chronic hepatitis C virus (HCV)-infected patients with cirrhosis are a high-priority population for treatment. To help inform the benefit-risk profile of the all-oral direct-acting antiviral (DAA) combination regimen of ombitasvir, paritaprevir, and ritonavir, with or without dasabuvir (OBV/PTV/r±DSV) in patients with Child-Pugh A cirrhosis, we undertook a comprehensive review of AbbVie-sponsored clinical trials enrolling patients with Child-Pugh A cirrhosis. METHODS Twelve phase II or III clinical trials of the 2-DAA regimen of OBV/PTV/r±ribavirin (RBV) or the 3-DAA regimen of OBV/PTV/r+DSV±RBV that included patients with Child-Pugh A cirrhosis were reviewed; patients who completed treatment by November 16, 2015 were included in a pooled, post hoc safety assessment. The number and percentage of patients with treatment-emergent adverse events (TEAEs), serious TEAEs, and TEAEs consistent with hepatic decompensation were reported. RESULTS In 1,066 patients with Child-Pugh A cirrhosis, rates of serious TEAEs and TEAEs leading to study drug discontinuation were 5.3% (95% confidence interval [CI]: 4.1-6.8) and 2.2% (95% CI: 1.4-3.2), respectively. Thirteen patients (1.2%; 95% CI: 0.7-2.1) had a TEAE that was consistent with hepatic decompensation. The most frequent TEAEs consistent with hepatic decompensation were ascites (n=8), esophageal variceal hemorrhage (n=4), and hepatic encephalopathy (n=2). CONCLUSIONS This pooled analysis in 1,066 HCV-infected patients with Child-Pugh A cirrhosis confirms the safety of OBV/PTV/r±DSV±RBV in this population. These results support the use of OBV/PTV/r±DSV±RBV in this high-priority population. Lay summary: This pooled safety analysis in 1,066 HCV-infected patients with compensated cirrhosis, receiving treatment with ombitasvir, paritaprevir, and ritonavir with or without dasabuvir, with or without ribavirin, shows that the rate of hepatic decompensation events was similar to previously reported rates in untreated patients.

Abstract
Liver cirrhosis is a major chronic disease in the field of digestive diseases. It causes more than one million deaths per year. Despite established evidence based guidelines, the adherence to standard of care or quality indicators are variable. Complete adherence to the recommendations of guidelines is less than 50%. To improve the quality of care in patients with cirrhosis, we need a more holistic view. Because of high rate of death due to cardiovascular disease and neoplasms, the care of comorbid conditions and risk factors such as smoking, hypertension, high blood sugar or cholesterol, would be important in addition to the management of primary liver disease. Despite a holistic multidisciplinary approach for this goal, the management of such patients should be patient centered and individualized. The diagnosis of underlying etiology and its appropriate treatment is the most important step. Definition and customizing the quality indicators for quality measure in patients are needed. Because most suggested quality indicators are designed for measuring the quality of care in decompensated liver cirrhosis, we need special quality indicators for compensated and milder forms of chronic liver disease as well. Training the patients for participation in their own management, design of special clinics with dedicated health professionals in a form of chronic disease model, is suggested for improvement of quality of care in this group of patients. Special day care centers by a dedicated gastroenterologist and a trained nurse may be a practical model for better management of such patients.

Abstract
Seventeen dogs were treated with L-ornithin-L-aspartate (LOLA; experimental group). Three dogs were treated with lactulose recognized therapy (control group). Following LOLA administration, 15 dogs experienced a significant decrease in ammonia level (p < 0.05) and showed clinical signs of improvement. However, there were no clinical signs of improvement in two dogs, even though the ammonia level decreased. Conversely, the clinical signs of the control group also improved and the ammonia level decreased, although these changes were not significant (p > 0.05). These results suggest that LOLA is an effective drug to treat hyperammonemia in veterinary medicine.

Abstract
AIM To evaluate the effect of lean management on the anxiety level and nursing satisfaction in outpatients with liver diseases.
METHODS Two hundred patients with liver diseases who underwent outpatient infusion from October 2012 to September 2014 were selected and divided into either a control group (treated from October 2012 to September 2013) or an observation group (treated from October 2013 to September 2014), with 100 cases in each group. The observation group adopted the nursing mode of lean management, while the control group received routine nursing. Before and after the infusion, the patients were assessed with the self-rating anxiety scale (SAS), and the SAS scores were compared between the two groups before and after intervention. At the end of the infusion, the satisfaction degree of patients was evaluated using the self-made nursing satisfaction questionnaire, and nursing satisfaction was compared between the two groups.
RESULTS Before intervention, there was no significant difference in SAS score between the control group and the observation group (59.4 ± 7.5 vs 59.1 ± 7.3, P > 0.05). After intervention, SAS score was significantly lower in the observation group than in the control group (52.8 ± 6.4 vs 52.8 ± 6.4, P < 0.05). The rate of nursing satisfaction was significantly higher in the control group than in the observation group (P < 0.05).
CONCLUSION Lean management can effectively relieve anxiety and improve nursing satisfaction in outpatients with liver diseases.

Abstract
AIM To verify how malnutrition is related to health-related quality of life (HRQL) impairment in patients with cirrhosis.
METHODS Data was retrospectively abstracted from medical records and obtained by direct interview. We included patients with cirrhosis from any etiology, evaluated at the Liver Clinic from Gastroenterology Department in a tertiary healthcare center, from June 2014 to June 2016. Child-Pugh score, data about complications, and demographic, clinical and anthropometric characteristics of patients were obtained. Nutritional status was evaluated by the Subjective Global Assessment (SGA). HRQL was evaluated through the Chronic Liver Disease Questionnaire. Patients were requested to assess their global HRQL with the following code: 0 = impairment of HRQL, when it was compared with other healthy subjects; 1 = good HRQL, if it was similar to the quality of life of other healthy subjects. To compare the primary outcome between malnourished and well-nourished groups, the χ2 test, Fisher’s exact test or Student’s t-test were used, based on the variable type. Associations between predictor variables and deterioration of HRQL were determined by calculating the hazard ratio and 95% confidence interval using Cox proportional hazards regression.
RESULTS A total of 127 patients with cirrhosis were included, and the mean age was 54.1 ± 12.3 years-old. According to Child-Pugh scoring, 25 (19.7%) were classified as A (compensated), 76 (59.8%) as B, and 26 (20.5%) as C (B/C = decompensated). According to SGA, 58 (45.7%) patients were classified as well-nourished. Sixty-nine patients identified HRQL as good, and 76 patients (59.8%) perceived impairment of their HRQL. Multivariate analysis to determine associations between predictor variables and self-perception of an impairment of HRQL found strong association with malnutrition (P < 0.0001). The most important impaired characteristics in malnourished patients were: Presence of body pain, dyspnea on exertion with daily activities, decreased appetite, generalized weakness, trouble lifting or carrying heavy objects, and decreased level of energy (P < 0.0001).
CONCLUSION Malnutrition is a key factor related to impairment of HRQL in patients with cirrhosis.

Abstract
BACKGROUND In this clinical trial, polyethylene glycol (PEG) solution was compared with lactulose in the treatment of hepatic encephalopathy in patients with cirrhosis. METHODS This randomized controlled trial was performed on 40 patients in two groups. The patients in the lactulose group received either 20-30 grams of lactulose orally or by a nasogastric tube, or 200 grams of lactulose enema by a rectal tube. The patients in the PEG-lactulose group received the same amount of oral or rectal lactulose, plus 280 grams of PEG in 4 liters of water orally as a single dose in 30-120 minutes. Serial physical examinations, hepatic encephalopathy scoring algorithm (HESA), blood level of ammonia, and serum biochemical studies were used to evaluate the severity of hepatic encephalopathy. RESULTS In comparison with lactulose alone, PEG-lactulose could improve HESA score in 24 hours more effectively (p =0.04). Overall, PEG-lactulose regimen was associated with a decrease in length of hospital stay compared with lactulose treatment (p =0.03) but in subgroup analysis we found that PEG-lactulose regimen could only decrease the length of hospital stay in women significantly (p =0.01). CONCLUSION The use of PEG along with lactulose in comparison with lactulose alone is more effective in the treatment of hepatic encephalopathy in patients with cirrhosis and results in more rapid discharge from hospital.

[PMID: 28457316 DOI: 10.1016/j.jss.2016.11.013] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/26/2016] [Revised: 10/11/2016] [Accepted: 11/04/2016] [Indexed: 02/07/2023]
Abstract
BACKGROUND Temporary abdominal closure (TAC) may be performed for cirrhotic patients undergoing emergent laparotomy. The effects of cirrhosis on physiologic parameters, resuscitation requirements, and outcomes following TAC are unknown. We hypothesized that cirrhotic TAC patients would have different resuscitation requirements and worse outcomes than noncirrhotic patients. METHODS We performed a 3-year retrospective cohort analysis of 231 patients managed with TAC following emergent laparotomy for sepsis, trauma, or abdominal compartment syndrome. All patients were initially managed with negative pressure wound therapy (NPWT) TAC with intention for planned relaparotomy and sequential abdominal closure attempts at 24- to 48-h intervals. RESULTS At presentation, cirrhotic patients had higher incidence of acidosis (33% versus 17%) and coagulopathy (87% versus 54%) than noncirrhotic patients. Forty-eight hours after presentation, cirrhotic patients had a persistently higher incidence of coagulopathy (77% versus 44%) despite receiving more fresh frozen plasma (10.8 units versus 4.4 units). Cirrhotic patients had higher NPWT output (4427 mL versus 2375 mL) and developed higher vasopressor infusion rates (57% versus 29%). Cirrhotic patients had fewer intensive care unit-free days (2.3 versus 7.6 days) and higher rates of multiple organ failure (64% versus 34%), in-hospital mortality (67% versus 21%), and long-term mortality (80% versus 34%) than noncirrhotic patients. CONCLUSIONS Cirrhotic patients managed with TAC are susceptible to early acidosis, persistent coagulopathy, large NPWT fluid losses, prolonged vasopressor requirements, multiple organ failure, and early mortality. Future research should seek to determine whether TAC provides an advantage over primary fascial closure for cirrhotic patients undergoing emergency laparotomy.

Abstract
OBJECTIVES Liver cirrhosis is a leading cause of morbidity and mortality in the USA. Diabetes is common and increasing in incidence. Patients with compensated cirrhosis and diabetes may be at greater risk of clinical decompensation. We examined the risk of decompensation among a large sample of working-aged insured patients dually diagnosed with compensated cirrhosis and diabetes. METHODS This retrospective study used MarketScan® Commercial Claims and Encounters and Medicare Supplemental Databases (2000-2013). Decompensation events included incident ascites, spontaneous bacterial peritonitis, variceal bleeding, hepatic encephalopathy, acute renal failure, and hepatocellular carcinoma. Dually diagnosed patients were defined as patients with cirrhosis and diabetes using previously published ICD-9 coding strategies. Adjusted odds ratios (ORs), hazard ratios (HRs), and confidence intervals (CI) were estimated using logistic regression and Cox proportional hazard models. RESULTS Of 72,731 patients with compensated cirrhosis, 20,477 patients (28.15 %) were diagnosed with diabetes. After controlling for patient characteristics and medication usage, the odds of developing any decompensation event were 1.14 times higher for patients with cirrhosis and diabetes than for patients with cirrhosis only (95 % CI 1.08-1.21, P value <0.01). In the Cox proportional hazard model, patients who were dually diagnosed with diabetes had a 1.32 times higher HR (95 % CI 1.26-1.39, P value <0.01) after controlling for time-to-event. CONCLUSIONS Patients dually diagnosed with compensated cirrhosis and diabetes had a higher risk of having decompensation events. Careful management of diabetes in patients with liver disease may reduce the risk of clinical decompensation in this population.

Abstract
BACKGROUND AND STUDY AIMS Chronic liver disease (CLD) can cause hepatopulmonary syndrome (HPS), defined as triad of liver disease, hypoxemia, and intrapulmonary vascular dilation (IPVD). The aim of this study was to determine the evidence of IPVD in a cohort of pediatric patients with CLD pre- and post-liver transplantation (LT). MATERIAL AND METHODS All pediatric patients with CLD listed for LT were studied. Pulse oxygen saturation (SpO(2)), technetium-99m-labeled macroaggregated albumin ((99m)Tc- MAA) perfusión scan (positive test: uptake of the isotope ≥ 6% in the brain), and echocardiography with saline bubble test (SBT) were performed. SBT was re-evaluated at 3-6 months after LT. Grading of SBT included grade 0 (no bubble), I (1-9 bubbles), grade II (10-20 bubbles), and grade III (> 20 bubbles). RESULTS Eighteen patients, median age 22.5 months (8-108), were enrolled. Most had biliary atresia (77.8%). Pre-LT, all patients had SpO(2) of 100% and none had positive (99)mTc- MAA perfusion scan. Two patients (11%) had negative SBT (grade 0), 1 (5.5%) had grade I, 3 (16.5%) had grade II, and 12 (67%) had grade III, respectively. Post-LT SBT became negative in all survivors (n = 16), (p = 0.0001). CONCLUSIONS Most cirrhotic children in this cohort study had evidence of IPVD by positive SBT. However, none of these met the criteria for diagnosis of HPS. This evidence of IPVD subsided after LT.

Abstract
Hydrodynamic gene delivery is a common method for gene transfer to the liver of small animals, and its clinical applicability in large animals has been demonstrated. Previous studies focused on functional analyses of therapeutic genes in animals with normal livers and little, however, is known regarding its effectiveness and safety in animals with liver fibrosis. Therefore, this study aimed to examine the effects of liver fibrosis on hydrodynamic gene delivery efficiency using a rat liver fibrosis model. We demonstrated for the first time, using pCMV-Luc plasmid, that this procedure is safe and that the amount of fibrotic tissue in the liver decreases gene delivery efficiency, resulting in decrease in luciferase activity depending on the volume of fibrotic tissue in the liver and the number of hepatocytes that are immunohistochemically stained positive for transgene product. We further demonstrate that antifibrotic gene therapy with matrix metalloproteinase-13 gene reduces liver fibrosis and improves efficiency of hydrodynamic gene delivery. These results demonstrate the negative effects of fibrotic tissue on hydrodynamic gene delivery and its recovery by appropriate antifibrotic therapy.

Abstract
Liver fibrosis is the excessive accumulation of extracellular matrix proteins in liver tissue. Liver fibrosis as the characteristic change of chronic liver injury has the potential to develop into liver cirrhosis, liver failure and hepatic carcinoma, and is considered a devastating pathologic process. However, recent studies demonstrate that liver fibrosis is not only reversible, but also can protect the liver from acute injury. Currently, the mechanisms of hepatoprotective effect of liver fibrosis have become a hot research area, which include promoted regeneration of the remaining normal liver cells and apoptotic resistance. In the present article, we will review the hepatoprotective effect of liver fibrosis and the underlying molecular mechanisms, aiming to provide a theoretical basis for understanding the pathogenesis of acute-on-chronic liver failure and provide new therapeutic targets for this disease.

Abstract
Liver, the largest intern organ of the human body, is responsible for several vital tasks such as digestive and excretory functions, as well as for nutrients storage and metabolic functions, synthesis of new molecules and purification of toxic chemicals. Cirrhosis, fibrosis and hepatocellular carcinoma are the most prevalent liver diseases. Despite all the studies performed so far, treatment options for these diseases are very limited. For this reason, it is urgent to find effective therapies for these pathologies. Several studies have been performed during the last decade about the possible application of human amniotic membrane in hepatic diseases therapy. Promising results about human amniotic membrane or its derived cells, in vitro and in vivo, applications in fibrosis, cirrhosis and hepatocellular carcinoma were already published. Since it is an attractive study area, it is becoming a dynamic scientific subject. However, the action mechanisms of human amniotic membrane and its derived cells in hepatic diseases therapy must be precisely known in order that this promising therapy could be clinically used.

Abstract
INTRODUCTION The p90 ribosomal S6 kinases (RSK) are a family of Ser/Thr protein kinases that are downstream effectors of MEK1/2-ERK1/2. Increased RSK activation is implicated in the etiology of multiple pathologies, including numerous types of cancers, cardiovascular disease, liver and lung fibrosis, and infections. AREAS COVERED The review summarizes the patent and scientific literature on small molecule modulators of RSK and their potential use as therapeutics. The patents were identified using World Intellectual Property Organization and United States Patent and Trademark Office databases. The compounds described are predominantly RSK inhibitors, but a RSK activator is also described. The majority of the inhibitors are not RSK-specific. EXPERT OPINION Based on the overwhelming evidence that RSK is involved in a number of diseases that have high mortalities it seems surprising that there are no RSK modulators that have pharmacokinetic properties suitable for in vivo use. MEK1/2 inhibitors are in the clinic, but the efficacy of these compounds appears to be limited by their side effects. We hypothesize that targeting the downstream effectors of MEK1/2, like RSK, are an untapped source of drug targets and that they will generate less side effects than MEK1/2 inhibitors because they regulate fewer effectors.

Abstract
Serum hyaluronic acid (HA) is a well-established marker of fibrosis in patients with chronic liver disease (CLD). However, the relationship between serum HA level and protein-energy malnutrition (PEM) in patients with CLD is an unknown. We aimed to examine the relationship between serum HA level and PEM in patients with chronic hepatitis C (CHC) compared with the relationships of other serum markers of fibrosis. A total of 298 CHC subjects were analyzed. We defined patients with serum albumin level of ≤3.5 g/dL and nonprotein respiratory quotient <0.85 using indirect calorimetry as having PEM. We investigated the effect of serum HA level on the presence of PEM. Receiver operating characteristic curve (ROC) analysis was performed for calculating the area under the ROC (AUROC) for serum HA level, platelet count, aspartate aminotransferase (AST) to platelet ratio index, FIB-4 index, AST to alanine aminotransferase ratio, and Forns index for the presence of PEM. The median serum HA level in this study was 148.0 ng/mL (range: 9.0-6340.0 ng/mL). In terms of the degree of liver function (chronic hepatitis, Child-Pugh A, B, and C), the analyzed patients were well stratified according to serum HA level (overall significance, P < 0.0001). The median value (range) of serum HA level in patients with PEM (n = 61) was 389.0 ng/mL (43.6-6340.0 ng/mL) and that in patients without PEM (n = 237) was 103.0 ng/mL (9.0-783.0 ng/mL) (P < 0.0001). Among 6 fibrosis markers, serum HA level yielded the highest AUROC with a level of 0.849 at an optimal cut-off value of 151.0 ng/mL (sensitivity 93.4%; specificity 62.0%; P < 0.0001). In the multivariate analysis, serum HA level was found to be a significant prognostic factor related to the presence of PEM (P = 0.0001).In conclusion, serum HA level can be a useful predictor of PEM in patients with CHC.

Abstract
Patients suffering from liver cirrhosis (LC) frequently require non-hepatic abdominal surgery, even before liver transplantation. LC is an important risk factor itself for surgery, due to the higher than average associated morbidity and mortality. This high surgical risk occurs because of the pathophysiology of liver disease itself and to the presence of contributing factors, such as coagulopathy, poor nutritional status, adaptive immune dysfunction, cirrhotic cardiomyopathy, and renal and pulmonary dysfunction, which all lead to poor outcomes. Careful evaluation of these factors and the degree of liver disease can help to reduce the development of complications both during and after abdominal surgery. In the emergency setting, with the presence of decompensated LC, alcoholic hepatitis, severe/advanced LC, and significant extrahepatic organ dysfunction conservative management is preferred. A multidisciplinary, individualized, and specialized approach can improve outcomes; preoperative optimization after risk stratification and careful management are mandatory before surgery. Laparoscopic techniques can also improve outcomes. We review the impact of LC on surgical outcome in non-hepatic abdominal surgeries required in this cirrhotic population before, during, and after surgery.

Abstract
Liver fibrosis is the final stage of liver diseases that lead to liver failure and cancer. While various diagnostic methods, including the use of serum marker, have been established, no standard therapy has been developed. The objective of this study was to assess the approach of overexpressing matrix metalloproteinase-13 gene (MMP13) in rat liver to prevent liver fibrosis progression. A rat liver fibrosis model was established by ligating the bile duct, followed by liver-targeted hydrodynamic gene delivery of a MMP13 expression vector, containing a CAG promoter-MMP13-IRES-tdTomato-polyA cassette. After 14 days, the serum level of MMP13 peaked at 71.7 pg/ml in MMP13-treated group, whereas the nontreated group only showed a level of ~5 pg/ml (P < 0.001). These levels were sustained for the next 60 days. The statistically lower level of the hyaluronic acids in treated group versus the nontreated group (P < 0.05) reveals the therapeutic effect of MMP13 overexpression. Quantitative analysis of tissue stained with sirius red showed a statistically larger volume of fibrotic tissue in the nontreated group compared to that of MMP13-treated rats (P < 0.05). These results suggest that the liver-targeted hydrodynamic delivery of MMP13 gene could be effective in the prevention of liver fibrosis.

[PMID: 26630543 DOI: 10.1111/1751-2980.12304] [Citation(s) in RCA: 13] [Impact Index Per Article: 1.6] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 03/05/2015] [Revised: 10/14/2015] [Accepted: 11/25/2015] [Indexed: 12/11/2022]
Abstract
OBJECTIVE Midodrine has been reported to improve systemic and renal hemodynamics in patients with cirrhotic ascites. However, the results of clinical trials are conflicting. The aim of this study is to evaluate the effects of midodrine on cirrhotic ascites through a meta-analysis and systematic review. METHODS We searched PubMed (January 1966-December 2014), EMBASE (January 1966-December 2014), the Cochrane Library (Issue 11, 2014), ScienceDirect (January 1966-December 2014), and the China National Knowledge Infrastructure (January 1979-December 2014) databases using the terms 'midodrine' AND 'cirrhosis' AND 'ascites' AND 'paracentesis' for all relevant randomized controlled trials using midodrine for treatment of cirrhotic ascites. RESULTS In all, 10 trials with a total of 462 patients were included. As a novel therapy for cirrhotic ascites, midodrine was not found to improve survival [odds ratio (OR) 0.81, 95% confidence interval (CI) 0.23-2.91]; although it might improve response rates (OR 3.36, 95% CI 1.47-7.69) and reduce plasma renin activity (MD -3.10, 95% CI -5.37 to -0.84). When midodrine was used as an alternative to albumin in large-volume paracentesis, the mortality was higher for midodrine than for albumin (OR 10.76, 95% CI 1.35-85.97). However, there was no statistically significant difference in the development of paracentesis-induced circulatory dysfunction between midodrine group and albumin group (OR 1.69, 95% CI 0.43-6.72). CONCLUSIONS Midodrine may have treatment effects on cirrhotic ascites. Better powered and well-designed trials are required to assess the extent of the efficacy of midodrine in specifically targeted patients.

Abstract
We aimed to elucidate the incidence of protein-energy malnutrition (PEM) in patients with chronic liver disease and to identify factors linked to the presence of PEM.A total of 432 patients with chronic liver disease were analyzed in the current analysis. We defined patients with serum albumin level of ≤3.5 g/dL and nonprotein respiratory quotient (npRQ) value using indirect calorimetry less than 0.85 as those with PEM. We compared between patients with PEM and those without PEM in baseline characteristics and examined factors linked to the presence of PEM using univariate and multivariate analyses.There are 216 patients with chronic hepatitis, 123 with Child-Pugh A, 80 with Child-Pugh B, and 13 with Child-Pugh C. Six patients (2.8%) had PEM in patients with chronic hepatitis, 17 (13.8%) in patients with Child-Pugh A, 42 (52.5%) in patients with Child-Pugh B, and 10 (76.9%) in patients with Child-Pugh C (P < 0.001). Multivariate analysis revealed that Child-Pugh classification (P < 0.001), age ≥64 years (P = 0.0428), aspartate aminotransferase (AST) ≥40 IU/L (P = 0.0023), and branched-chain amino acid to tyrosine ratio (BTR) ≤5.2 (P = 0.0328) were independent predictors linked to the presence of PEM. On the basis of numbers of above risk factors (age, AST, and BTR), the proportions of patients with PEM were well stratified especially in patients with early chronic hepatitis or Child-Pugh A (n = 339, P < 0.0001), while the proportions of patients with PEM tended to be well stratified in patients with Child-Pugh B or C (n = 93, P = 0.0673).Age, AST, and BTR can be useful markers for identifying PEM especially in patients with early stage of chronic liver disease.

Abstract
Hepatic encephalopathy (HE) is defined by an altered mental status in the setting of portosystemic shunting, with or without cirrhosis. The basis of HE is probably multi-factorial, but increased ammonia delivery to the brain is thought to play a pivotal role. Medical therapies have typically focused on reducing blood ammonia concentrations. These measures are moderately effective, but further improvements will require identification of new therapeutic targets. Two medications, lactulose and rifaximin, are currently approved for the treatment of HE in the USA - new compounds are available off-label, and are in clinical trials. The presence of HE is associated with a higher risk of death in cirrhotic patients. Liver transplantation typically cures HE, but HE does not increase the MELD score, and therefore does not contribute to the likelihood of liver transplantation.

Abstract
Until recently, anti-platelet/coagulation therapy had not been recommended for patients with cirrhosis. Although venous thrombosis is one of the representative complications of cirrhosis and ischemic disorders associated with atherosclerosis are not infrequent in cirrhotic patients, many clinicians have tended to hesitate to introduce anti-platelet/coagulation therapy to their patients. Undoubtedly, this is due to the increased risk of hemorrhagic diathesis in cirrhotic patients. However, accumulating evidence has revealed the benefits of anti-platelet/coagulation therapy for cirrhotic patients. In addition to the safety of the therapy carried out against cardiovascular diseases in cirrhotic patients, some clinical data have indicated its preventive effect on venous thrombosis. Moreover, the efficacy of anti-platelet/coagulation therapy against cirrhosis itself has been demonstrated both clinically and experimentally. The conceptual basis for application of anti-platelet/coagulation therapy against cirrhosis was constructed through two pathologic studies on intrahepatic thrombosis in cirrhotic livers. It may be better to use thrombopoietin-receptor agonists, which have been tested as a treatment for cirrhosis-related thrombocytopenia, in combination with anti-platelet drugs to reduce the risk of venous thrombosis. During the last decade, the World Journal of Gastroenterology, a sister journal of World Journal of Hepatology, has been one of the main platforms of active discussion of this theme.

World J Gastroenterol 2015; 21:4126-4135. [PMID: 25892862 PMCID: PMC4394073 DOI: 10.3748/wjg.v21.i14.4126] [Citation(s) in RCA: 4] [Impact Index Per Article: 0.4] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 06/12/2014] [Revised: 07/30/2014] [Accepted: 10/15/2014] [Indexed: 02/06/2023] Open
Abstract
AIM: Portal hypertension is a common complication of liver cirrhosis and significantly increases mortality and morbidity. Previous reports have suggested that the compound thalidomide attenuates portal hypertension (PHT). However, the mechanism for this action is not fully elucidated. One hypothesis is that thalidomide destabilizes tumor necrosis factor α (TNFα) mRNA and therefore diminishes TNFα induction of nitric oxide synthase (NOS) and the production of nitric oxide (NO). To examine this hypothesis, we utilized the murine partial portal vein ligation (PVL) PHT model in combination with endothelial or inducible NOS isoform gene knockout mice.
METHODS: Wild type, inducible nitric oxide synthase (iNOS)-/- and endothelial nitric oxide synthase (eNOS)-/- mice received either PVL or sham surgery and were given either thalidomide or vehicle. Serum nitrate (total nitrate, NOx) was measured daily for 7 d as a surrogate of NO synthesis. Serum TNFα level was quantified by enzyme-linked immunosorbent assay. TNFα mRNA was quantified in liver and aorta tissue by reverse transcription-polymerase chain reaction. PHT was determined by recording splenic pulp pressure (SPP) and abdominal aortic flow after 0-7 d. Response to thalidomide was determined by measurement of SPP and mean arterial pressure (MAP).
RESULTS: SPP, abdominal aortic flow (Qao) and plasma NOx were increased in wild type and iNOS-/- PVL mice when compared to sham operated control mice. In contrast, SPP, Qao and plasma NOx were not increased in eNOS-/- PVL mice when compared to sham controls. Serum TNFα level in both sham and PVL mice was below the detection limit of the commercial ELISA used. Therefore, the effect of thalidomide on serum TNFα levels was undetermined in wild type, eNOS-/- or iNOS-/- mice. Thalidomide acutely increased plasma NOx in wild type and eNOS-/- mice but not iNOS-/- mice. Moreover, thalidomide temporarily (0-90 min) decreased mean arterial pressure, SPP and Qao in wild type, eNOS-/- and iNOS-/- PVL mice, after which time levels returned to the respective baseline.
CONCLUSION: Thalidomide does not reduce portal pressure in the murine PVL model by modulation of NO biosynthesis. Rather, thalidomide reduces PHT by decreasing MAP by an undetermined mechanism.

Systematic review with network meta-analysis: the comparative effectiveness and safety of interventions in patients with overt hepatic encephalopathy. Aliment Pharmacol Ther 2015; 41:624-35. [PMID: 25684317 DOI: 10.1111/apt.13122] [Citation(s) in RCA: 61] [Impact Index Per Article: 6.8] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 09/19/2014] [Revised: 10/21/2014] [Accepted: 01/26/2015] [Indexed: 12/13/2022]
Abstract
BACKGROUND Interventional treatment for overt hepatic encephalopathy (OHE), includes non-absorbable disaccharides, neomycin, rifaximin, L-ornithine-L-aspartate and branched chain amino acids (BCAA). However, the optimum regimen remains inconclusive. AIM To compare interventions in terms of patients' adverse events and major clinical outcomes. METHODS Literature search of PubMed, Embase, Scopus, and Cochrane Library studies published up to July 31 2014. RCTs of above interventions in OHE patients were included. Network meta-analysis combined direct and indirect evidence to estimate odds ratios (ORs) and mean difference (MD) between treatments and the probabilities of ranking for treatment based on clinical outcomes. RESULTS Twenty eligible RCTs were included. When compared with observation, only L-ornithine-L-aspartate (OR 3.71, P < 0.001) and BCAA (OR 3.37, P < 0.001) improved clinical efficacy significantly. However, when L-ornithine-L-aspartate was compared with BCAA, non-absorbable disaccharides and neomycin, there was a trend suggesting that L-ornithine-L-aspartate may be the most effective intervention with respect to clinical improvement (OR 1.10), rifaximin (OR 1.31), non-absorbable disaccharides (OR 2.75), neomycin (OR 2.22). In addition, L-ornithine-L-aspartate (MD -20.18, 95% CI -40.12 to -0.27) provided a significant reduction in blood ammonia concentration compared with observation. Neomycin appeared to be associated with more adverse events in comparison with non-absorbable disaccharides (OR 10.15), rifaximin (OR 17.31), L-ornithine-L-aspartate (OR 3.16) or BCAA (OR 7.69). CONCLUSIONS L-ornithine-L-aspartate treatment may show a trend in superiority for clinical efficacy among standard interventions for OHE. Rifaximin shows the greatest reduction in blood ammonia concentration, and treatment with neomycin demonstrates a higher probability in causing adverse effects among the five compared interventions.

Abstract
Chronic liver diseases, such as chronic hepatitis B (CHB) and chronic hepatitis C (CHC), are characterized by the presence of liver fibrosis, which may ultimately lead to cirrhosis. The progression of fibrosis is associated with various factors. Here, we review recent advances in the study of factors related to the progression rate of CHB- and CHC-induced fibrosis. Identification of these factors and establishment of a scoring system for cirrhosis risk are particularly important for predicting cirrhosis development, planning individualized treatment, and preventing fibrosis progression.
