Abstract
INTRODUCTION Classically, clinical practice guidelines and expert recommendations have focused on the management of decompensated cirrhotic patients, so we focused this review on improving care for compensated cirrhotic patients who are followed up in outpatient clinics. AREAS COVERED We reviewed the current methods for establishing liver function, the diagnosis and management of advanced chronic liver disease and clinically significant portal hypertension as well as the prevention of its complications, with special attention to covert hepatic encephalopathy, we also paid attention to the extrahepatic complications of cirrhosis and the palliative care. All this from the perspective of evidence-based medicine and trying to empower precision medicine. The literature search was undertaken by PubMed with 'cirrhosis,' 'advanced chronic liver disease,' 'liver function,' 'portal hypertension,' 'covert hepatic encephalopathy,' 'minimal hepatic encephalopathy,' 'palliative care' as MeSH terms. EXPERT OPINION We must offer compensated cirrhotic patients specific care and measures to prevent the progression of the disease and the appearance of its complications beyond the calculation of liver function and imaging screening for hepatocellular carcinoma that we perform every six months. Entities that have typically received little attention, such as covert hepatic encephalopathy, extrahepatic complications and symptoms of cirrhosis, and palliative care, must come to the spotlight.

Predisposing and precipitating risk factors for delirium in gastroenterology and hepatology: Subgroup analysis of 718 patients from a hospital-wide prospective cohort study. Front Med (Lausanne) 2022; 9:1004407. [PMID: 36530904 PMCID: PMC9747774 DOI: 10.3389/fmed.2022.1004407] [Citation(s) in RCA: 2] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/27/2022] [Accepted: 11/15/2022] [Indexed: 11/15/2023] Open
Abstract
BACKGROUND AND AIMS Delirium is the most common acute neuropsychiatric syndrome in hospitalized patients. Higher age and cognitive impairment are known predisposing risk factors in general hospital populations. However, the interrelation with precipitating gastrointestinal (GI) and hepato-pancreato-biliary (HPB) diseases remains to be determined. PATIENTS AND METHODS Prospective 1-year hospital-wide cohort study in 29'278 adults, subgroup analysis in 718 patients hospitalized with GI/HPB disease. Delirium based on routine admission screening and a DSM-5 based construct. Regression analyses used to evaluate clinical characteristics of delirious patients. RESULTS Delirium was detected in 24.8% (178/718). Age in delirious patients (median 62 years [IQR 21]) was not different to non-delirious (median 60 years [IQR 22]), p = 0.45). Dementia was the strongest predisposing factor for delirium (OR 66.16 [6.31-693.83], p < 0.001). Functional impairment, and at most, immobility increased odds for delirium (OR 7.78 [3.84-15.77], p < 0.001). Patients with delirium had higher in-hospital mortality rates (18%; OR 39.23 [11.85-129.93], p < 0.001). From GI and HPB conditions, cirrhosis predisposed to delirium (OR 2.11 [1.11-4.03], p = 0.023), while acute renal failure (OR 4.45 [1.61-12.26], p = 0.004) and liver disease (OR 2.22 [1.12-4.42], p = 0.023) were precipitators. Total costs were higher in patients with delirium (USD 30003 vs. 10977; p < 0.001). CONCLUSION Delirium in GI- and HPB-disease was not associated with higher age per se, but with cognitive and functional impairment. Delirium needs to be considered in younger adults with acute renal failure and/or liver disease. Clinicians should be aware about individual risk profiles, apply preventive and supportive strategies early, which may improve outcomes and lower costs.

Prediction of Patient Hepatic Encephalopathy Risk with Freiburg Index of Post-TIPS Survival Score Following Transjugular Intrahepatic Portosystemic Shunts: A Retrospective Study. Int J Gen Med 2022; 15:4007-4016.

Abstract
Background Hepatic encephalopathy is a complication of portal hypertension. The Freiburg index of transjugular portosystemic shunt (TIPS) and patient outcomes have recently been described. This retrospective study was conducted at a single center in China and included 241 patients with portal hypertension who underwent TIPS implantation to evaluate the Freiburg index of post-TIPS survival score (FIPS) to predict hepatic encephalopathy. Methods A single-center retrospective study including 241 patients who underwent TIPS operation between April 2015 and July 2019 was conducted. Clinical demographics and relevant clinical parameters within 24h after admission were collected. The prediction performances of FIPS, Child–Pugh and the model for end-stage liver disease (MELD) scores were compared by decision curve analysis and receiver operating characteristic (ROC) curve analysis. In addition, multivariate analyses were performed to identify independent predictors. Results Eighty-three out of 241 patients (34.4%) finally developed post-TIPS hepatic encephalopathy. The area under the ROC curve of FIPS was 0.744 (95% confidence interval: 0.684–0.798). FIPS was identified as an independent risk factor for post-TIPS hepatic encephalopathy (hazard ratio: 2.23, 95% confidence interval: 1.71–2.90, p<0.001). Moreover, we further grouped the FIPS scores into two categories (FIPS ≤-0.97, low-risk; FIPS >-0.97, high risk) to improve its applicability. Patients with high FIPS scores had a significantly higher incidence of hepatic encephalopathy than patients with low FIPS scores (P<0.05). Conclusion This study showed that FIPS could be used to evaluate the risk of hepatic encephalopathy in this patient group with improved predictive performance when compared with the Child–Pugh and MELD scores.

Effect of Branched-Chain Amino Acid Infusion on In-Hospital Mortality of Patients With Hepatic Encephalopathy and End-Stage Kidney Disease: A Retrospective Cohort Study Using a National Inpatient Database. J Ren Nutr 2021; 32:432-440. [PMID: 34452811 DOI: 10.1053/j.jrn.2021.05.008] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/22/2021] [Revised: 05/07/2021] [Accepted: 05/30/2021] [Indexed: 12/13/2022] Open
Abstract
OBJECTIVES Renal failure and hepatic cirrhosis are mutually aggravating factors. However, no specific therapeutic strategies for hepatic encephalopathy (HE) and end-stage kidney disease have been established. The coexistence, with an extremely poor prognosis, makes randomized controlled trials unfeasible. We evaluated whether an infusion of branched-chain amino acids was associated with mortality in patients hospitalized for HE and end-stage kidney disease. DESIGN AND METHODS Using the Japanese Diagnosis Procedure Combination database, we retrospectively identified patients with HE and end-stage kidney disease who received hemodialysis within 2 days of admission from July 2011 to March 2017. We divided the patients into those who received branched-chain amino acid infusion within 2 days of admission and those who did not. We conducted analyses using overlap weights based on propensity scores to compare in-hospital mortality between the groups. Sub-group analysis was conducted by stratifying patients by Child-Pugh class. RESULTS We identified 553 eligible patients, including 503 patients who received branched-chain amino acid infusion and 50 who did not. The patients who received branched-chain amino acid infusion had lower mortality than those who did not (10.2% vs. 20.1%, relative risk 0.51, 95% confidence interval 0.27-0.95). Sub-group analysis showed that branched-chain amino acid infusion was associated with decreased in-hospital mortality in patients with Child-Pugh class C (16.2% vs. 39.0%, relative risk 0.41, 95% confidence interval 0.23-0.76). CONCLUSIONS Branched-chain amino acid infusion may improve the prognosis of HE in patients with end-stage kidney disease, particularly those with lower liver function. Further research is necessary to provide a suitable treatment for HE in patients with end-stage kidney disease.

A nomogram to predict the risk of hepatic encephalopathy after transjugular intrahepatic portosystemic shunt in Cirrhotic Patients. Sci Rep 2020; 10:9381. [PMID: 32523059 PMCID: PMC7287049 DOI: 10.1038/s41598-020-65227-2] [Citation(s) in RCA: 22] [Impact Index Per Article: 5.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/27/2020] [Accepted: 04/20/2020] [Indexed: 01/17/2023] Open
Abstract
BACKGROUND AND AIM Hepatic encephalopathy (HE) is a serious complication of decompensated liver cirrhosis, affecting the prognosis of patients underwent transjugular intrahepatic portosystemic shunts (TIPS). We aim to create a nomogram to predict hepatic encephalopathy- free survivals (HEFS) after TIPS in cirrhotic patients and select appropriate candidates for TIPS. METHODS Cirrhotic patients underwent TIPS from 2015 to 2018 in our department were included. Multivariable Cox regression was conducted to estimate the predictors of overt HE (OHE) after TIPS within one year. A nomogram based on the Cox proportional hazard model using data from a retrospective training cohort (70% of the patients) was developed. Then the prediction model was validated in the remaining 30% patients by Harrell's C-indexes, ROC curves and calibration plots. RESULTS Of 373 patients, 117 developed postoperative OHE (31.4%). The training and validation groups comprised 83 (31.4%) and 34 (31.2%) patients, respectively. The cumulative survival rates of patients with HE at 1, 2 and 3 years were 90%, 83% and 76%, respectively. The nomogram included the following variables: age, Child-Turcotte-Pugh class (CTP class), diabetes mellitus (DM), serum creatinine and serum sodium (C-index = 0.772). The C-index for HEFS prediction was 0.773 for the validation cohort. The ROC for predicting HEFS was 0.809 and 0.783, respectively. CONCLUSIONS We created a nomogram of predicting postoperative HEFS in cirrhotic patients received TIPS. This nomogram could be an important tool of HE risk prediction before TIPS to guide the therapeutic strategy in cirrhotic patients.

Abstract
Hepatic encephalopathy is a neuropsychological syndrome due to biochemical disturbance of brain function in advanced liver disease patients. Diagnosis and treatment of the condition is very demanding and has negative toll on finances with increased healthcare utilization. The pathophysiology is not completely understood; however, there is evidence that ammonia plays an important role in the etiology. Conventional methods of solely relying on blood ammonia level to diagnose hepatic encephalopathy did not help much; likewise, the use of lactulose alone in treating hepatic encephalopathy has also been discouraged. This paper analyzed the current knowledge regarding the mechanism of how ammonia disrupts the normal brain function as well as the use of latest diagnosing tools including those under development to evaluate the neuropsychiatric state of patients and their quality of life. The efficacies of lactulose and rifaximin combination for short-term and long-term treatment in addition to nutritional interventions and other drugs undergoing clinical trials were also reviewed.

Abstract
Mild cognitive dysfunction as in minimal or covert hepatic encephalopathy (HE) can be found in a variety of metabolic disturbances, several neurological diseases, and even older age. Because liver cirrhosis usually is accompanied by one or the other of these, a differentiation between HE and cognitive decline because of comorbidities is difficult. Somehow discriminating is the impairment of motor speed and accuracy, which is more prominent in HE than in any of the comorbidities. The observation that, for example, diabetes mellitus, renal dysfunction, infections, or hyponatremia as well as older age increase the risk of developing HE indicates the interaction between these factors and liver dysfunction in the development of HE and the necessity to adjust the therapy accordingly.

Plasma Glucose Level Is Predictive of Serum Ammonia Level After Retrograde Occlusion of Portosystemic Shunts. AJR Am J Roentgenol 2017; 209:W169-W176.

Abstract
OBJECTIVE The purpose of this study was to evaluate predictors of reduction in ammonia levels by occlusion of portosystemic shunts (PSS) in patients with cirrhosis. MATERIALS AND METHODS Forty-eight patients with cirrhosis (21 women, 27 men; mean age, 67.8 years) with PSS underwent balloon-occluded retrograde transvenous obliteration (BRTO) at one institution between February 2008 and June 2014. The causes of cirrhosis were hepatitis B in one case, hepatitis C in 20 cases, alcohol in 15 cases, nonalcoholic steatohepatitis in eight cases, and other conditions in four cases. The Child-Pugh classes were A in 24 cases, B in 23 cases, and C in one case. The indication for BRTO was gastric varices in 40 cases and hepatic encephalopathy in eight cases. Testing was conducted before and 1 month after the procedure. Statistical analyses were performed to identify predictors of a clinically significant decline in ammonia levels after BRTO. RESULTS Occlusion of PSS resulted in a clinically significant decrease in ammonia levels accompanied by increased portal venous flow and improved Child-Pugh score. Univariate analyses showed that a reduction in ammonia levels due to BRTO was significantly related to lower plasma glucose levels, higher RBC counts, and higher hemoglobin concentration before the treatment. Furthermore, multivariate logistic regression identified preoperative plasma glucose level as the strongest independent predictor of a significant ammonia reduction in response to BRTO. In addition, although BRTO resulted in significantly declined ammonia levels in patients with normal glucose tolerance before the procedure, ammonia levels were not significantly decreased after shunt occlusion in patients with diabetes mellitus or impaired glucose tolerance before BRTO, according to 75-g oral glucose tolerance test results. CONCLUSION Preoperative plasma glucose level is a useful predictor of clinically significant ammonia reduction resulting from occlusion of PSS in patients with cirrhosis. Even if PSS are present, control of blood ammonia levels by BRTO alone may be difficult in patients with glucose intolerance.

Abstract
Hepatic encephalopathy (HE) is a reversible syndrome of impaired brain function occurring in patients with advanced liver diseases. The precise pathophysiology of HE is still under discussion; the leading hypothesis focus on the role of neurotoxins, impaired neurotransmission due to metabolic changes in liver failure, changes in brain energy metabolism, systemic inflammatory response and alterations of the blood brain barrier. HE produces a wide spectrum of nonspecific neurological and psychiatric manifestations. Minimal HE is diagnosed by abnormal psychometric tests. Clinically overt HE includes personality changes, alterations in consciousness progressive disorientation in time and space, somnolence, stupor and, finally, coma. Except for clinical studies, no specific tests are required for diagnosis. HE is classified according to the underlying disease, the severity of manifestations, its time course and the existence of precipitating factors. Treatment of overt HE includes supportive therapies, treatment of precipitating factors, lactulose and/or rifaximin. Routine treatment for minimal HE is only recommended for selected patients.

Abstract
BACKGROUND Acute renal failure (ARF) after liver transplantation requiring continuous renal replacement therapy (CRRT) adversely affects patient survival. We suggested that postoperative renal failure can be predicted if a clinically simple nomogram can be developed, thus selecting potential risk factors for preventive strategy. METHODS We retrospectively reviewed the medical records of 153 liver transplant recipients from January 2008 to December 2011 at Severance Hospital, Yonsei University Health System, in Seoul, Korea. There were 42 patients treated with CRRT (20 and 22 patients received transplants from living and deceased donors, respectively) and 115 were not. Univariate and stepwise logistic multivariate analyses were performed. A clinical nomogram to predict postoperative CRRT application was constructed and validated internally. RESULTS Hepatic encephalopathy (HEP; odds ratio OR, 5.47), deceased donor liver donations (OR, 3.47), Model for End-Stage Liver Disease (MELD) score (OR, 1.09), intraoperative blood loss (L; OR, 1.16), and tumor (hepatocellular carcinoma) as the indication for liver transplantation (OR, 0.11) were identified as independent predictive factors for postoperative CRRT on multivariate analysis. A clinical prediction model constructed for calculating the probability of CRRT post-transplantation was 1.7000 × HEP + [-4.5427 + 1.2440 × (deceased donor) + 0.0830 × (MELD score) + 0.000149 × the amount of intraoperative bleeding (L) - 2.1785 × tumor]. The validation set discriminated well with an area under the curve (AUC) of 0.90 (95% confidence interval, 0.85-0.95). The predicted and the actual probabilities were calibrated with the clinical nomogram. CONCLUSIONS We developed a predictive model of postoperative CRRT in liver transplantation patients. Perioperative strategies to modify these factors are needed.

Abstract
BACKGROUND Although muscle wasting may lead to decreased ammonia detoxification in cirrhosis, the potential role of lean mass depletion in hepatic encephalopathy (HE) has not been explored. Anemia, hormonal abnormalities, and psychological distress may contribute to cognitive dysfunction, but data on their potential relation to HE are limited. METHODS Data on 108 cirrhotic liver transplant candidates enrolled in a prospective study on fatigue were retrospectively analyzed. HE was assessed clinically and with the number connection tests (NCT) A and B. Psychosocial distress was assessed with a validated questionnaire. Fasting serum glucose, insulin, ammonia, and the glomerular filtration rate (GFR) were measured. Fat and fat-free mass was evaluated with dual-energy X-ray absorptiometry. Serum cortisol, testosterone, dehydroepiandrosterone, thyroid function tests, interleukin-6, and tumor necrosis factor-α (TNF-α) were measured in a subgroup of 80 patients. RESULTS A total of 28% of patients had (overt or minimal) HE. Anemia was present in 59%, diabetes in 29%, renal impairment in 16%, and fat-free mass depletion in 14%. In multivariate analysis, fat-free mass depletion was an independent predictor of HE and NCT-A; renal impairment of NCT-A and -B; and anemia of NCT-B (p < 0.05 for all). HE was also independently related to international normalized ratio and TNF-α (p < 0.05 for both), but not to other hormonal abnormalities or psychological distress. Plasma ammonia was independently associated to anemia (beta = 15.24, p = 0.049), fasting insulin (beta = 0.26, p < 0.05), and GFR (beta = -0.43, p = 0.003). CONCLUSIONS Anemia and fat-free mass depletion are predictors of HE in cirrhotic liver transplant candidates along with liver failure, renal impairment, and systemic inflammation.

Abstract
Hepatic encephalopathy (HE) is a neuropsychiatric complex syndrome, ranging from subtle behavioral abnormalities to deep coma and death. Hepatic encephalopathy emerges as the major complication of acute or chronic liver failure. Multiplicity of factors are involved in its pathophysiology, such as central and neuromuscular neurotransmission disorder, alterations in sleep patterns and cognition, changes in energy metabolism leading to cell injury, an oxidative/nitrosative state and a neuroinflammatory condition. Moreover, in acute HE, a condition of imminent threat of death is present due to a deleterious astrocyte swelling. In chronic HE, changes in calcium signaling, mitochondrial membrane potential and long term potential expression, N-methyl-D-aspartate-cGMP and peripheral benzodiazepine receptors alterations, and changes in the mRNA and protein expression and redistribution in the cerebral blood flow can be observed. The main molecule indicated as responsible for all these changes in HE is ammonia. There is no doubt that ammonia, a neurotoxic molecule, triggers or at least facilitates most of these changes. Ammonia plasma levels are increased two- to three-fold in patients with mild to moderate cirrhotic HE and up to ten-fold in patients with acute liver failure. Hepatic and inter-organ trafficking of ammonia and its metabolite, glutamine (GLN), lead to hyperammonemic conditions. Removal of hepatic ammonia is a differentiated work that includes the hepatocyte, through the urea cycle, converting ammonia into GLN via glutamine synthetase. Under pathological conditions, such as liver damage or liver blood by-pass, the ammonia plasma level starts to rise and the risk of HE developing is high. Knowledge of the pathophysiology of HE is rapidly expanding and identification of focally localized triggers has led the development of new possibilities for HE to be considered. This editorial will focus on issues where, to the best of our knowledge, more research is needed in order to clarify, at least partially, controversial topics.

Abstract
BACKGROUND & AIMS We performed a prospective study to evaluate fatigue and identify potential determinants among patients with cirrhosis. We also studied the effects of liver transplantation on fatigue in these patients. METHODS A total of 108 patients with cirrhosis being evaluated before liver transplantation completed the fatigue impact scale (FIS), the hospital anxiety and depression (HAD) scale, and the short-form 36 (SF-36). Results were compared with controls from the general population. Fasting serum levels of insulin and glucose were measured in all patients. Levels of serum thyrotropin, free T(3) and T(4), cortisol, free testosterone, dehydroepiandrosterone sulfate, estradiol, interleukin-6, and tumor necrosis factor-α were measured in a subgroup of 80 patients. Transplant recipients were followed for 1 year. RESULTS Compared with controls, patients with cirrhosis had more pronounced fatigue, on the basis of higher FIS domain and total scores (P < .05), which were related to all SF-36 domains (r = -0.44 to -0.77, P < .001). All FIS scores improved significantly after liver transplantation, although physical fatigue levels remained higher than in controls (P < .05). In multivariate analysis, pretransplant FIS scores were only related to depression, anxiety, cirrhosis severity, and low serum levels of cortisol (P < .05 for all). Impaired renal function and anemia were independent predictors of physical fatigue (P < .05). CONCLUSIONS Fatigue is common among patients with cirrhosis and associated with impaired quality of life. Psychological distress, severity of cirrhosis, and low levels of cortisol determine general fatigue, whereas anemia and impaired renal function also contribute to physical fatigue. Physical fatigue remains of concern for patients who have received liver transplants for cirrhosis.

Abstract
Hyponatraemia is common in patients with advanced cirrhosis and is associated with remarkable changes in brain cells, particularly a reduction in myoinositol and other intracellular organic osmolytes related to the hypo-osmolality of the extracellular fluid. It has been recently suggested that hyponatraemia may be an important factor associated with the development of overt hepatic encephalopathy (HE). To test this hypothesis, we retrospectively analysed the incidence and predictive factors of overt HE using a database of 70 patients with cirrhosis included in a prospective study comparing transjugular intrahepatic portosystemic shunts (TIPS) vs large-volume paracentesis in the management of refractory of ascites. Variables used in the analysis included age, sex, previous history of HE, treatment assignment (TIPS vs large volume paracentesis plus albumin), treatment with diuretics, serum bilirubin, serum creatinine and serum sodium concentration. Laboratory parameters were measured at entry, at 1 month and every 3 months during follow-up and at the time of development of HE in patients who developed this complication. During a mean follow-up of 10 months, 50 patients (71%) developed 117 episodes of HE. In the whole population of patients, the occurrence of HE was independently associated with serum hyponatraemia, serum bilirubin and serum creatinine. In conclusion, in patients with refractory ascites, the occurrence of HE is related to the impairment of liver and renal function and presence of hyponatraemia.
