Prophylaxis of hepatic encephalopathy: current and future drug targets

Hepatic encephalopathy is described by a broad spectrum of neurological and psychiatric aberrations resulting due to advanced liver dysfunction. It is a neurological disorder due to hepatic insufficiency and/or portosystemic shunts. Its clinical presentation includes neuropsychiatric dysfunction ranging from subclinical changes to comatose state. It is a sign of poor prognosis in cirrhotics with a high 1-year mortality. Each episode of hepatic encephalopathy leads to high hospitalization rate, poor prognosis and raised burden of healthcare. Primary prophylaxis is prevention of initial occurrence and secondary prophylaxis is prevention of reappearance of hepatic encephalopathy in subjects who had prior history. Early detection and management of triggers is very important in the treatment of hepatic encephalopathy. The initial choice of treatment is still lactulose, as it is effective in minimal, overt, and recurrent hepatic encephalopathy. Rifaximin is equally effective as lactulose in managing hepatic encephalopathy and is better tolerated. Branch chain amino acids are beneficial in subjects who are protein intolerant. L-ornithine L-aspartate and probiotics are also useful in the management of hepatic encephalopathy. Rifaximin along with lactulose is effective in managing overt and recurrent hepatic encephalopathy. Large portosystemic shunts embolization and liver transplant is efficacious in certain group of patients. Nutritional therapy and fecal microbiota transplantation are newer therapies for hepatic encephalopathy but the evidences are limited, more research is required to prove their efficacy. Involvement of hospital pharmacists, telemedicine, and providing education are also beneficial in managing hepatic encephalopathy.

Recurrence of portosystemic encephalopathy in cirrhotic patients and its risk factors

Objectives

Recurrent episodes of Portal Systemic Encephalopathy (PSE), poses a significant burden of illness on the patients and healthcare system. The objective of this study was to assess the recurrence of PSE in cirrhotic patients after index episode of PSE and to identify various risk factors associated with it.

Methods

A retrospective, single-centre study was conducted at Aga Khan University Hospital over a span of one year. Patients who were admitted first time with PSE and admitted within three months of index PSE were enrolled in the study. Variables assessed were demographic data, associated comorbid conditions, aetiology of cirrhosis, Child-Turcotte-Pugh (CTP) score, Model of End-Stage Liver Disease (MELD) score, PSE grade, laboratory tests, ascites with spontaneous bacterial peritonitis (SBP), variceal bleeding. Statistical analysis was done and variables of those who developed recurrence were compared with those who did not.

Results

Fifty one patients were recruited. Thirty three (64.7%) were readmitted with PSE. On comparative analysis of both groups; infection, Meld score, low albumin, and raised total bilirubin showed significant P-value (<0.05).

Conclusion

Identification of risk factors during assessment can reduce the recurrence of PSE. We would recommend to validate result of our study on a large scale prospectively.

[Sarcopenia in Chronic Liver Disease]

Sarcopenia is a crucial factor in assessing the nutritional status of chronic liver disease patients and predicting their prognosis and survival. The serum ammonia level is closely associated with sarcopenia regarding ammonia, a key regulator in the liver-muscle axis. In addition, various changes in energy metabolism and hormones are also involved in sarcopenia. The psoas muscle area can represent the overall skeletal muscle mass in liver disease patients. Therefore, measuring the psoas muscle area with computed tomography or magnetic resonance imaging is considered an objective and reliable method for assessing muscle mass. Providing sufficient calorie and protein intake is crucial for preventing and treating sarcopenia. In addition, engaging in appropriate exercise and addressing concurrent hormonal and metabolic changes can be helpful.

Predicting which patients with cirrhosis will develop overt hepatic encephalopathy: Beyond psychometric testing

It remains challenging to identify covert hepatic encephalopathy and predict progression to overt hepatic encephalopathy. Psychometric testing is a widely used diagnostic modality, but it is often inaccurate and difficult to implement in diverse populations, making it a less than ideal assessment. Alternatively, by using easily accessible data from the electronic health record, simple clinical assessment tools, and patient-reported outcomes, we may be better able to predict hepatic encephalopathy across multiple populations. Furthermore, incorporation of patient-reported outcomes into our diagnostic toolset not only aids detection of covert hepatic encephalopathy and prediction of overt hepatic encephalopathy, but also allows us to target therapies and track their impact. Herein, we outline a potential algorithm based on these easily integrated tools to promote patient risk-stratification and early therapeutic intervention.

Inadequate practices for hepatic encephalopathy management in the inpatient setting

Hepatic encephalopathy (HE) is an important complication of decompensated liver disease. Hospital admission for episodes of HE are very common, with these patients being managed by the hospitalists. These admissions are costly and burdensome to the health-care system. Diagnosis of HE at times is not straightforward, particularly in patients who are altered and unable to provide any history. Precipitants leading to episodes of HE, should be actively sought and effectively tackled along with the overall management. This mandates timely diagnostics, appropriate initiation of pharmacological treatment, and supportive care. Infections are the most important precipitants leading to HE and should be aggressively managed. Lactulose is the front-line medication for primary treatment of HE episodes and for prevention of subsequent recurrence. However, careful titration in the hospital setting along with the appropriate route of administration should be established and supervised by the hospitalist. Rifaximin has established its role as an add-on medication, in those cases where lactulose alone is not working. Overall effective management of HE calls for attention to guideline-directed nutritional requirements, functional assessment, medication reconciliation, patient education/counseling, and proper discharge planning. This will potentially help to reduce readmissions, which are all too common for HE patients. Early specialty consultation may be warranted in certain conditions. Numerous challenges exist to optimal care of hospitalized OHE patients. However, hospitalists if equipped with knowledge about a systematic approach to taking care of these frail patients are in an ideal position to ensure good inpatient and transition of care outcomes.

Hepatic Encephalopathy-Related Hospitalizations in Cirrhosis: Transition of Care and Closing the Revolving Door

Cirrhosis is associated with substantial morbidity and mortality. Development of complications of cirrhosis, including hepatic encephalopathy (HE), portends poorer outcomes. HE is associated with hospital readmission, impaired patient and caregiver quality of life, risk of falls, and mortality. Guidelines recommend lactulose as first-line therapy for HE and rifaximin in combination with lactulose for reducing the risk of HE recurrence. Improving post-discharge outcomes, including readmissions, is an important aspect in the management of patients with HE. Approaches focused on improving management and prevention of HE, including properly titrating lactulose dosing, overcoming medication-related nonadherence, and incorporating rifaximin as therapy to reduce the risk of recurrence, as well as incorporating supportive care initiatives, may ease the transition from hospital to home. Strategies to decrease readmission rates include using hospital navigators, who can offer patient/caregiver education, post-discharge planning, and medication review; and involving pharmacists in post-discharge planning. Similarly, telemedicine offers providers the opportunity to monitor patients with HE remotely and improves outcomes. Providers offering transitional care management may be reimbursed when establishing contact with patients within 2 days post-discharge and conducting an outpatient visit within 7 days or 14 days. Several approaches have been shown to improve outcomes broadly in patients post-discharge and may also be effective for improving outcomes specifically in patients hospitalized with cirrhosis and HE, thus closing the revolving door on rehospitalizations in this population.

The Future of Quality Improvement for Cirrhosis

Cirrhosis has a significant and growing impact on public health and patient-reported outcomes (PROs). The increasing burden of cirrhosis has led to an emphasis on the quality of care with the goal of improving overall outcomes in this high-risk population. Existing evidence has shown the significant gaps in quality across process measures (eg, hepatocellular carcinoma screening), highlighting the need for consistent measurement and interventions to address the gaps in quality care. This multistep process forms the quality continuum, and it depends on clearly defined process measures, real-time quality measurement, and generalizable evaluative methods. Herein we review the current state of quality care in cirrhosis across the continuum with a focus on process measurement methodologies, developments in PRO evaluation on quality assessment, practical examples of quality improvement initiatives, and the recent emphasis placed on the value of primary prevention.
