Impact of Hepatic Encephalopathy in Cirrhosis on Quality-of-Life Issues

Hepatic encephalopathy (HE) has a major impact on health-related quality of life (HRQOL) in patients, which has clinical and psychosocial consequences. HRQOL in cirrhosis has been measured by generic and liver-specific instruments, with most studies indicating a negative impact of HE. HRQOL abnormalities span daily functioning, sleep-wake cycle changes, and the ability to work. Of these, sleep-wake cycle changes have a major effect on HRQOL, which remains challenging to treat. The personal effect of HRQOL is modulated by the presence of HE, the etiology of cirrhosis, and cognitive reserve. Patients with higher cognitive reserve are able to tolerate HE and its impact on HRQOL better than those with a poor cognitive reserve. The impact of HRQOL impairment is felt by patients (higher mortality and poor daily functioning), as well as by caregivers and families. Caregivers of patients with HE bear a major financial and psychological burden, which may affect their personal health and longevity

The Relationship between Marital Status and Psychological Resilience in Chronic Pain

We examined the relationship between marital status and a 2-stage model of pain-related effect, consisting of pain unpleasantness and suffering. We studied 1914 chronic pain patients using multivariate analysis of covariance (MANCOVA) to clarify whether marital status was a determinant factor in the emotional or ideational suffering associated with chronic pain after controlling for pain sensation intensity, age, and ethnicity. Marital status was unrelated to immediate unpleasantness (). We found a strong association with emotional suffering () but not with negative illness beliefs (). Interestingly, widowed subjects experienced significantly less frustration, fear, and anger than all other groups (married, divorced, separated, or single). A final MANCOVA including sex as a covariate revealed that the emotional response to pain was the same for both widow and widower. Only those individuals whose spouse died experienced less emotional turmoil in the face of a condition threatening their lifestyle. These data suggest that after experiencing the death of a spouse, an individual may derive some “emotional inoculation” against future lifestyle threat

Hepatic encephalopathy : novel insights into classification, pathophysiology and therapy

Hepatic encephalopathy (HE) is a frequent and serious complication of both chronic liver disease and acute liver failure. HE manifests as a wide spectrum of neuropsychiatric abnormalities, from subclinical changes (mild cognitive impairment) to marked disorientation, confusion and coma. The clinical and economic burden of HE is considerable, and it contributes greatly to impaired quality of life, morbidity and mortality. This review will critically discuss the latest classification of HE, as well as the pathogenesis and pathophysiological pathways underlying the neurological decline in patients with end-stage liver disease. In addition, management strategies, diagnostic approaches, currently available therapeutic options and novel treatment strategies are discussed

Symptom Domain Groups of the Patient-Reported Outcomes Measurement Information System Tools Independently Predict Hospitalizations and Re-hospitalizations in Cirrhosis

Background Patient-Reported Outcomes Measurement Information System (PROMIS) tools can identify health-related quality of life (HRQOL) domains that could differentially affect disease progression. Cirrhotics are highly prone to hospitalizations and re-hospitalizations, but the current clinical prognostic models may be insufficient, and thus studying the contribution of individual HRQOL domains could improve prognostication. Aim Analyze the impact of individual HRQOL PROMIS domains in predicting time to all non-elective hospitalizations and re-hospitalizations in cirrhosis. Methods Outpatient cirrhotics were administered PROMIS computerized tools. The first non-elective hospitalization and subsequent re-hospitalizations after enrollment were recorded. Individual PROMIS domains significantly contributing toward these outcomes were generated using principal component analysis. Factor analysis revealed three major PROMIS domain groups: daily function (fatigue, physical function, social roles/activities and sleep issues), mood (anxiety, anger, and depression), and pain (pain behavior/impact) accounted for 77% of the variability. Cox proportional hazards regression modeling was used for these groups to evaluate time to first hospitalization and re-hospitalization. Results A total of 286 patients [57 years, MELD 13, 67% men, 40% hepatic encephalopathy (HE)] were enrolled. Patients were followed at 6-month (mth) intervals for a median of 38 mths (IQR 22–47), during which 31% were hospitalized [median IQR mths 12.5 (3–27)] and 12% were re-hospitalized [10.5 mths (3–28)]. Time to first hospitalization was predicted by HE, HR 1.5 (CI 1.01–2.5, p = 0.04) and daily function PROMIS group HR 1.4 (CI 1.1–1.8, p = 0.01), independently. In contrast, the pain PROMIS group were predictive of the time to re-hospitalization HR 1.6 (CI 1.1–2.3, p = 0.03) as was HE, HR 2.1 (CI 1.1–4.3, p = 0.03). Conclusions Daily function and pain HRQOL domain groups using PROMIS tools independently predict hospitalizations and re-hospitalizations in cirrhotic patients

Acute-on-Chronic Liver Failure: Getting ready for prime-time

Acute on chronic liver failure (ACLF) is a culmination of chronic liver disease and extra-hepatic organ failures, which is associated with a high short-term mortality and immense healthcare expenditure. There are varying definitions for organ failures and ACLF in Europe, North America and Asia. These differing definitions need to be reconciled to enhance progress in the field. The pathogenesis of ACLF is multi-factorial and related to interactions between the immuno-inflammatory system, microbiota and the precipitating factors. Individual organ failures related to the kidney, brain, lungs and circulation have cumulative adverse effects on mortality and are often complicated or precipitated by infections. Strategies to prevent and rapidly treat these organ failures are paramount in improving survival. With the aging population and paucity of organs for liver transplant, the prognosis of ACLF patients is poor, highlighting the need for novel therapeutic strategies. The role of liver transplant in ACLF is evolving and needs further investigation across large consortia. A role for early palliative care and management of frailty as approaches to alleviate disease burden and improve patient-reported outcomes is being increasingly recognized. CONCLUSION: ACLF is a clinically relevant syndrome that is epidemic worldwide and which requires a dedicated multi-national approach focused on prognostication and management. Investigations are underway worldwide to get ACLF ready for prime time. Compensated cirrhosis with \u3e 90% 1-year survival can transition into the decompensated stage with the onset of jaundice, ascites, variceal bleeding and hepatic encephalopathy (HE) (1)Acute on chronic liver failure (ACLF) is associated with rapid deterioration of liver function leading to liver failure, multiple extra-hepatic organ failures and high short-term mortality (2). Even if patients survive the acute insult, they may never return to their pre-episode functional state (3). The term acute decompensation has been used to characterize ascites, gastrointestinal bleeding, hepatic encephalopathy or infections without organ failure(4). There are several gaps in knowledge surrounding ACLF, which will be highlighted in this review. The prevalence of ACLF is difficult to assess due to varying regional definitions (5). ACLF, once thought to occur only in decompensated cirrhosis, has been recognized even in chronic liver disease without cirrhosis (5). ACLF occurs in approximately 10-30% of hospitalized cirrhotic patients (6-8). Because of its acuity, patients are frequently admitted into the intensive care unit (ICU), and every effort is made to stabilize these patients for liver transplantation (LT). This drives healthcare costs(9). Despite this intensive management, ACLF is associated with substantial morbidity and mortality. Because curative LT is only available to \u3c 10% of cirrhotic patients each year and ACLF patients are often delisted, the morbidity and mortality rates remain high, especially with an increasing number of organ failures (10)

Modulation of the Metabiome by Rifaximin in Patients with Cirrhosis and Minimal Hepatic Encephalopathy

Hepatic encephalopathy (HE) represents a dysfunctional gut-liver-brain axis in cirrhosis which can negatively impact outcomes. This altered gut-brain relationship has been treated using gut-selective antibiotics such as rifaximin, that improve cognitive function in HE, especially its subclinical form, minimal HE (MHE). However, the precise mechanism of the action of rifaximin in MHE is unclear. We hypothesized that modulation of gut microbiota and their end-products by rifaximin would affect the gut-brain axis and improve cognitive performance in cirrhosis. Aim To perform a systems biology analysis of the microbiome, metabolome and cognitive change after rifaximin in MHE. Methods Twenty cirrhotics with MHE underwent cognitive testing, endotoxin analysis, urine/serum metabolomics (GC and LC-MS) and fecal microbiome assessment (multi-tagged pyrosequencing) at baseline and 8 weeks post-rifaximin 550 mg BID. Changes in cognition, endotoxin, serum/urine metabolites (and microbiome were analyzed using recommended systems biology techniques. Specifically, correlation networks between microbiota and metabolome were analyzed before and after rifaximin. Results There was a significant improvement in cognition(six of seven tests improved,pVeillonellaceaeand increase inEubacteriaceae was observed. Rifaximin resulted in a significant reduction in network connectivity and clustering on the correlation networks. The networks centered onEnterobacteriaceae, Porphyromonadaceae and Bacteroidaceae indicated a shift from pathogenic to beneficial metabolite linkages and better cognition while those centered on autochthonous taxa remained similar. Conclusions Rifaximin is associated with improved cognitive function and endotoxemia in MHE, which is accompanied by alteration of gut bacterial linkages with metabolites without significant change in microbial abundance.

Rifaximin Exerts Beneficial Effects Independent of its Ability to Alter Microbiota Composition

Rifaximin has clinical benefits in minimal hepatic encephalopathy (MHE) but the mechanism of action is unclear. The antibiotic-dependent and -independent effects of rifaximin need to be elucidated in the setting of MHE-associated microbiota. To assess the action of rifaximin on intestinal barrier, inflammatory milieu and ammonia generation independent of microbiota using rifaximin
