Project description:Decreased magnetization transfer ratio (MTR) in the brain characterizes cerebral edema (CE) in patients with liver cirrhosis, but the role of treatment on its reversibility has not been studied in patients who have minimal hepatic encephalopathy (MHE). This study was carried to evaluate the reversibility of CE with lactulose and rifaximin treatment in patients with MHE and role of ammonia, pro-inflammatory interleukins (IL-1, IL-6) and tumor necrosis factor (TNF)-? in its pathogenesis.Twenty-three patients with cirrhosis (14 with MHE, 9 without MHE (NMHE)) and 6 healthy controls underwent ammonia, IL-1, IL-6, TNF-? estimation, and MTR in frontal white matter (FWM), parietal white matter (PWM), internal capsule (IC), and basal ganglia (BG).Ammonia was significantly higher in the cirrhosis group compared with controls and in MHE compared with the NMHE group. Ammonia correlated positively with IL-1 and IL-6. MTRs in FWM, PWM, IC, and BG were significantly lower in the MHE group compared with controls and in PWM, IC, and BG compared with the NMHE group. MHE patients showed significant MTR increase in FWM, PWM, and IC with treatment. IL-6 and ammonia had significant negative and significant positive psychometric hepatic encephalopathy score (PHES) correlation with MTR in various regions.This study, for the first time, demonstrated the reversibility of low-grade CE with treatment in patients with MHE. Negative correlation between ammonia, IL-6 levels, and MTR and positive correlation between PHES and MTR in MHE patients suggests the role of inflammation and ammonia in the genesis of low-grade CE.

Project description:IntroductionCirrhotic patients with portal hypertension can suffer from variceal bleeding or refractory ascites and can benefit from a transjugular intrahepatic portosystemic shunt (TIPS). Post-TIPS hepatic encephalopathy (HE) is a common (20%-54%) and often severe complication. A prophylactic strategy is lacking.Methods and analysisThe Prevention of hepatic Encephalopathy by Administration of Rifaximin and Lactulose in patients with liver cirrhosis undergoing placement of a TIPS (PEARL) trial, is a multicentre randomised, double blind, placebo controlled trial. Patients undergoing covered TIPS placement are prescribed either rifaximin 550?mg two times per day and lactulose 25?mL two times per day (starting dose) or placebo 550?mg two times per day and lactulose 25?mL two times per day from 72?hours before and until 3?months after TIPS placement. Primary endpoint is the development of overt HE (OHE) within 3?months (according to West Haven criteria). Secondary endpoints include 90-day mortality; development of a second episode of OHE; time to development of episode(s) of OHE; development of minimal HE; molecular changes in peripheral and portal blood samples; quality of life and cost-effectiveness. The total sample size is 238 patients and recruitment period is 3?years in six hospitals in the Netherlands and one in Belgium.Ethics and disseminationThis study protocol was approved in the Netherlands by the Medical Research Ethics Committee of the Academic Medical Centre, Amsterdam (2018-332), in Belgium by the Ethics Committee Research UZ/KU Leuven (S62577) and competent authorities. This study will be conducted in accordance with Good Clinical Practice guidelines and the principles of the Declaration of Helsinki. Study results will be submitted for publication in a peer-reviewed journal.Trial registration numbersClinicalTrials.gov (NCT04073290) and EudraCT database (2018-004323-37).

Project description:BackgroundHepatic encephalopathy (HE) is a complex neuropsychiatric syndrome associated with liver failure and/or portal systemic shunting. Polyethylene glycol (PEG) electrolyte solution is a commonly used for catharsis of gut, which has been demonstrated to relieve HE in a number of randomized controlled trials. The aim of this paper was to evaluate the comparative efficacy and safety of PEG with lactulose for current HE treatment.MethodsPEG electrolyte solution versus lactulose of HE was deeply studied by conducting a systematic search in electronic databases and other sources until December 31, 2020. The PRISMA statement recommended the use of meta-analysis with 95% confidence interval (CI), relative risk (RR), and weighted mean deviation (WMD) as the estimated effect size. A sensitivity analysis was performed comprehensively to present the risk of bias and the source of heterogeneity.ResultsA total of 434 patients were involved in 7 randomized studies. It is found that there was a significant advantage of PEG therapy in the increase of clinical efficacy (RR=1.46; 95% CI: 1.26-1.68; P=0.000; I2=0.0%) and the decrease of hospital stay (WMD=-1.78; 95% CI: -2.72 to 0.85; P=0.000; I2=90.1%). There was no significant difference in the incidence of adverse events (RR=0.75; 95% CI: 0.48-1.19; P=0.222>0.05; I2=7.2%) and the level of serum ammonia (WMD=9.02; 95% CI: -14.39 to 32.43; P=0.45>0.05; I2=84.9%) after 24 hours between the 2 groups.ConclusionsThe results prove that PEG has a beneficial effect on the treatment of HE. Compared with lactulose, PEG can lead to more rapid HE resolution during the first 24 hours and shorten the length of stay without increasing the rate of adverse effects.

Project description:UNLABELLED:Altered gut microbiome is associated with systemic inflammation and cirrhosis decompensation. However, the correlation of the oral microbiome with inflammation in cirrhosis is unclear. Our aim was to evaluate the oral microbiome in cirrhosis and compare with stool microbiome. Outpatients with cirrhosis (with/without hepatic encephalopathy [HE]) and controls underwent stool/saliva microbiome analysis (for composition and function) and also systemic inflammatory evaluation. Ninety-day liver-related hospitalizations were recorded. Salivary inflammation was studied using T helper 1 cytokines/secretory immunoglobulin A (IgA), histatins and lysozyme in a subsequent group. A total of 102 patients with cirrhosis (43 previous HE) and 32 age-matched controls were included. On principal component analysis (PCA), stool and saliva microbiome clustered far apart, showing differences between sites as a whole. In salivary microbiome, with previous HE, relative abundance of autochthonous families decreased whereas potentially pathogenic ones (Enterobacteriaceae, Enterococcaceae) increased in saliva. Endotoxin-related predicted functions were significantly higher in cirrhotic saliva. In stool microbiome, relative autochthonous taxa abundance reduced in previous HE, along with increased Enterobacteriaceae and Enterococcaceae. Cirrhotic stool microbiota demonstrated a significantly higher correlation with systemic inflammation, compared to saliva microbiota, on correlation networks. Thirty-eight patients were hospitalized within 90 days. Their salivary dysbiosis was significantly worse and predicted this outcome independent of cirrhosis severity. Salivary inflammation was studied in an additional 86 age-matched subjects (43 controls/43 patients with cirrhosis); significantly higher interleukin (IL)-6/IL-1?, secretory IgA, and lower lysozyme, and histatins 1 and 5 were found in patients with cirrhosis, compared to controls. CONCLUSIONS:Dysbiosis, represented by reduction in autochthonous bacteria, is present in both saliva and stool in patients with cirrhosis, compared to controls. Patients with cirrhosis have impaired salivary defenses and worse inflammation. Salivary dysbiosis was greater in patients with cirrhosis who developed 90-day hospitalizations. These findings could represent a global mucosal-immune interface change in cirrhosis.

Project description:There is limited evidence to support the belief that benzodiazepines increase cirrhosis patients' risk of hepatic encephalopathy (HE).We aimed to examine the association between benzodiazepine use and HE development in cirrhosis patients.We used data on 865 cirrhosis patients with ascites from three trials to study the effect of benzodiazepine use on development of first-time HE. For each patient, we classified periods of benzodiazepine use by the number of days since initiation. We used Cox regression to compare the risk of HE in current benzodiazepine users vs. non-users adjusting for confounders.Cirrhosis patients were not at increased risk of HE for the first two days of benzodiazepine use, but then faced a five-fold increased risk of HE during days 3 to 10 of benzodiazepine use. The risk of HE was not increased for those who had been using benzodiazepines for more than 28 days.Cirrhosis patients who had begun using benzodiazepines between 3 and 10 days previously had a markedly increased risk of developing first-time HE. Cirrhosis patients who had been using benzodiazepines for just one or two days or continued use for more than 28 days did not have such an excess risk.

Project description:BackgroundHepatic encephalopathy is a devastating complication of cirrhosis.AimTo describe the outcomes after developing hepatic encephalopathy among contemporary, aging patients.MethodsWe examined data for a 20% random sample of United States Medicare enrolees with cirrhosis and Part D prescription coverage from 2008 to 2014. Among 49 164 persons with hepatic encephalopathy, we evaluated the associations with transplant-free survival using Cox proportional hazard models with time-varying covariates (hazard ratios, HR) and incidence rate ratios (IRR) for healthcare utilisation measured in hospital-days and 30-day readmissions per person-year. We validated our findings in an external cohort of 2184 privately insured patients with complete laboratory values.ResultsHepatic encephalopathy was associated with median survivals of 0.95 and 2.5 years for those ≥65 or <65 years old and 1.1 versus 3.9 years for those with and without ascites. Non-alcoholic fatty-liver disease posed the highest adjusted risk of death among aetiologies, HR 1.07 95% CI (1.02, 1.12). Both gastroenterology consultation and rifaximin utilisation were associated with lower mortality, respective adjusted-HR 0.73 95% CI (0.67, 0.80) and 0.40 95% CI (0.39, 0.42). Thirty-day readmissions were fewer for patients seen by gastroenterologists (0.71 95% CI [0.57-0.88]) and taking rifaximin (0.18 95% CI [0.08-0.40]). Lactulose alone was associated with fewer hospital-days, IRR 0.31 95% CI (0.30-0.32), than rifaximin alone, 0.49 95% CI (0.45-0.53), but the optimal therapy combination was lactulose/rifaximin, IRR 0.28 95% CI (0.27-0.30). These findings were validated in the privately insured cohort adjusting for model for endstage liver disease-sodium score and serum albumin.ConclusionsHepatic encephalopathy remains morbid and associated with poor outcomes among contemporary patients. Gastroenterology consultation and combination lactulose-rifaximin are both associated with improved outcomes. These data inform the development of care coordination efforts for subjects with cirrhosis.

Project description:BackgroundCirrhosis is associated with increased perioperative risks related to hepatic decompensation. However, data are lacking regarding the incidence and outcomes of postoperative hepatic encephalopathy (HE).ObjectiveTo determine the incidence of HE postoperatively, factors associated with its development, and its association with in-hospital mortality.MethodsRetrospective cohort study of 583 patients with cirrhosis undergoing non-hepatic surgery over a 10-year period. Outcomes included postoperative HE and in-hospital mortality and were, respectively, evaluated using multi-state modeling and Fine-Gray competing risk regression (with postoperative HE as a time-varying covariate).ResultsOverall, the median Model for End-Stage Liver Disease Sodium was 10, 61.7% had a history of ascites, 49.9% esophageal varices, and 34.6% HE. The most common surgeries including abdominal/non-bowel (33.3%), orthopedic (18.0%), and bowel (12.2%). A total of 42 (7.2%) patients developed HE postoperatively during admission. The cumulative risk of HE was 7.2%, which was most associated with a history of HE, ASA class, postoperative AKI, and postoperative infection. In-hospital mortality occurred in 34 (5.8%) individuals. Only ASA class was independently associated (HR 2.46, 95%CI 1.21-5.02), but there was a trend for postoperative HE (HR 1.71, 95%CI 0.73-3.98).DiscussionHE is an uncommon but not rare postoperative complication that increases the risk of patient harm. This study implies its development is predictable. Consequently, at-risk patients should have consultation with a hepatologist before undergoing elective surgery.

Project description:IMPORTANCE:Hepatic encephalopathy (HE) is a common cause of hospitalization in patients with cirrhosis. Pharmacologic treatment for acute (overt) HE has remained the same for decades. OBJECTIVE:To compare polyethylene glycol 3350-electrolyte solution (PEG) and lactulose treatments in patients with cirrhosis admitted to the hospital for HE. We hypothesized that rapid catharsis of the gut using PEG may resolve HE more effectively than lactulose. DESIGN, SETTING, AND PARTICIPANTS:The HELP (Hepatic Encephalopathy: Lactulose vs Polyethylene Glycol 3350-Electrolyte Solution) study is a randomized clinical trial in an academic tertiary hospital of 50 patients with cirrhosis (of 186 screened) admitted for HE. INTERVENTIONS:Participants were block randomized to receive treatment with PEG, 4-L dose (n?=?25), or standard-of-care lactulose (n?=?25) during hospitalization. MAIN OUTCOMES AND MEASURES:The primary end point was an improvement of 1 or more in HE grade at 24 hours, determined using the hepatic encephalopathy scoring algorithm (HESA), ranging from 0 (normal clinical and neuropsychological assessments) to 4 (coma). Secondary outcomes included time to HE resolution and overall length of stay. RESULTS:A total of 25 patients were randomized to each treatment arm. Baseline clinical features at admission were similar in the groups. Thirteen of 25 patients in the standard therapy arm (52%) had an improvement of 1 or more in HESA score, thus meeting the primary outcome measure, compared with 21 of 23 evaluated patients receiving PEG (91%) (P?<?.01); 1 patient was discharged before final analysis and 1 refused participation. The mean (SD) HESA score at 24 hours for patients receiving standard therapy changed from 2.3 (0.9) to 1.6 (0.9) compared with a change from 2.3 (0.9) to 0.9 (1.0) for the PEG-treated groups (P?=?.002). The median time for HE resolution was 2 days for standard therapy and 1 day for PEG (P?=?.01). Adverse events were uncommon, and none was definitely study related. CONCLUSIONS AND RELEVANCE:PEG led to more rapid HE resolution than standard therapy, suggesting that PEG may be superior to standard lactulose therapy in patients with cirrhosis hospitalized for acute HE.

Project description:Cirrhosis and hepatic encephalopathy (HE) can adversely affect survival, but their effect on socioeconomic and emotional burden on the family is not clear. The aim was to study the emotional and socioeconomic burden of cirrhosis and HE on patients and informal caregivers.A cross-sectional study in two transplant centers (Veterans and University) of cirrhotic patients and their informal caregivers was performed. Demographics for patient/caregivers, model-for-end-stage liver disease (MELD) score, and cirrhosis complications were recorded. Patients underwent a cognitive battery, sociodemographic, and financial questionnaires. Caregivers were given the perceived caregiver burden (PCB; maximum=155) and Zarit Burden Interview (ZBI)-Short Form (maximum=48) and questionnaires for depression, anxiety, and social support.A total of 104 cirrhotics (70% men, 44% previous HE, median MELD 12, 49% veterans) and their caregivers (66% women, 77% married, relationship duration 32±14 years) were included. Cirrhosis severely impacted the family unit with respect to work (only 56% employed), finances, and adherence. Those with previous HE had worse unemployment (87.5 vs. 19%, P=0.0001) and financial status (85 vs. 61%, P=0.019) and posed a higher caregiver burden; PCB (75 vs. 65, P=0.019) and ZBI (16 vs. 11, P=0.015) compared with others. Cognitive performance and MELD score were significantly correlated with employment and caregiver burden. Veterans and non-veterans were equally affected. On regression, depression score, MELD, and cognitive tests predicted both PCB and ZBI score.Previous HE and cognitive dysfunction are associated with worse employment, financial status, and caregiver burden. Cirrhosis-related expenses impact the family unit's daily functioning and medical adherence. A multidisciplinary approach to address this burden is required.
