Patients with cirrhosis experience a worsened quality of life; this may be quantified by the use of health-related QoL (HRQoL) constructs, such as the chronic liver disease questionnaire (CLDQ) and ...EuroQoL Group-visual analog scale (EQ-VAS). In this multicenter prospective study, we aimed to evaluate HRQoL as a predictor of unplanned hospital admission/early mortality, identify HRQoL domains most affected in cirrhosis, and identify predictors of low HRQoL in patients with cirrhosis.
Multivariable logistic regression was used to determine independent association of HRQoL with primary outcome and identify predictors of low HRQoL. HRQoL was also compared with population norms.
In this cohort of 402 patients with cirrhosis, mean model for end-stage liver disease was 12.5 (4.9). More than 50% of the cohort had low HRQoL, considerably lower than population norms. HRQoL (measured by either CLDQ or EQ-VAS) was independently associated with the primary outcome of short-term unplanned hospitalization/mortality. Every 1-point increase in the CLDQ and every 10-point increase in the EQ-VAS reduced the risk of reaching this outcome by 30% and 13%, respectively. Patients with cirrhosis had lower HRQoL scores than population norms across all domains of the CLDQ. Younger age, female sex, current smoker, lower serum albumin, frailty, and ascites were independently associated with low CLDQ.
Patients with cirrhosis experience poor HRQoL. HRQoL is independently associated with increased mortality/unplanned hospitalizations in patients with cirrhosis and could be an easy-to-use prognostic screen that patients could complete in the waiting room before their appointment.
Chronic hepatitis C virus (HCV) is a highly burdensome public health problem in Canada, causing more years of life lost than any other infectious disease in the country. A recent modelling study ...suggested that about 252 000 Canadians (uncertainty interval: 178 000-315 000 Canadians) were chronically infected in 2013. The birth cohort of 1945-1975 has the highest prevalence of chronic HCV infection, yet it is estimated that up to 70% of this group have not been tested for HCV. The primary objective of anti-HCV therapy is complete eradication of the virus, termed a sustained virologic response, which is defined as absence of viremia 12 weeks after completion of therapy. 5 Once achieved, sustained virologic response is considered a true cure of the viral infection, as late relapses are very uncommon. The landscape for HCV treatment continues to change at a rapid pace. This guideline provides updated evidence-based recommendations for the treatment of patients with HCV infection.
Background and Aims
The Liver Frailty Index (LFI) is a well‐studied tool that evaluates frailty in patients with cirrhosis. Consisting of grip strength, chair stands, and balance testing, the LFI has ...been associated with increased mortality in patients awaiting liver transplant. We aimed to extend our understanding of frailty in cirrhosis by exploring the relationship between the LFI and the risk of (1) cirrhosis progression, (2) mortality, and (3) unplanned hospitalizations, in both compensated and decompensated disease.
Approach and Results
Adult patients with cirrhosis from four centers in North America and one in India were included. Frailty was measured at baseline using the LFI and categorized as robust (LFI < 3.2), prefrail (LFI 3.2–4.5), and frail (LFI > 4.5). Progression of cirrhosis was defined by an increase in clinical stage, ranging from 1 to 5, from baseline using the D’Amico classification. Factors associated with progression, mortality, and hospitalizations were evaluated using multivariate regression models, with transplant as a competing risk. In total, 822 patients with cirrhosis were included. Average Model for End‐Stage Liver Disease (MELD) score was 15.5 ± 6.0. In patients with compensated cirrhosis, being frail versus robust was associated with increased risk of progression to the next cirrhosis stage or to death (HR, 2.45; 95% CI, 1.14–5.29) and with an increased risk of unplanned hospitalizations (2.32; 95% CI, 1.13–4.79), after adjusting for age, sex, and MELD score. Similar HRs were observed in patients with decompensated cirrhosis.
Conclusions
Frailty was an independent predictor of cirrhosis progression or death and unplanned hospitalization across patients with compensated and decompensated cirrhosis. Future studies are needed to evaluate the possibility of slowing cirrhosis disease progression by reversing or preventing frailty.
Purpose
To show the contribution of CEUS to characterization of indeterminate MRI observations in high-risk patients for hepatocellular carcinoma (HCC).
Methods
From July to December 2015, 42 ...consecutive patients referred to CEUS with indeterminate MRI scans comprise our study cohort. There are 50 indeterminate nodule-like observations and 10 arterial phase hyperenhancing foci, suggesting pseudolesions/arterio-portal shunts. MRI and CEUS lesions are classified according to their enhancement features in all phases and Liver Imaging and Reporting Data System (LI-RADS) in a blind read format. Clinical pathologic correlation and 24 months follow-up are performed.
Results
A majority, 37/50 (74%), of indeterminate nodule-like observations have arterial phase enhancement without washout on MRI. CEUS further characterizes enhancement and shows washout in 14/37 (38%). In total, CEUS diagnoses 16 malignant lesions in 14 patients including 14 HCC and 2 ICC. 12/16 (75%) malignant lesions are confirmed by biopsy or follow-up. Ultrasound identification of a nodule differentiates real nodules from pseudolesions. Of the ten suspected arterial-portal shunts on MRI, two show a real nodule on ultrasound, confirmed as an HCC and a regenerative nodule. 15/42 (36%) patients have LI-RADS escalated from LR-3 or 4 on MRI to LR-4 or 5 on CEUS. Overall, the sensitivity of CEUS is (13/16) 81.3% and specificity is (37/37) 100% for malignant diagnosis.
Conclusion
Grayscale ultrasound detects true nodules. Dynamic CEUS detects and characterizes washout, correctly predicting HCC. CEUS is complimentary to MRI and can serve as a problem-solving tool when MRI is indeterminate.
Screening tools to determine which outpatients with cirrhosis are at highest risk for unplanned hospitalization are lacking. Frailty is a novel prognostic factor but conventional screening for ...frailty is time consuming. We evaluated the ability of a 1 min bedside screen (Clinical Frailty Scale (CFS)) to predict unplanned hospitalization or death in outpatients with cirrhosis and compared the CFS with two conventional frailty measures (Fried Frailty Criteria (FFC) and Short Physical Performance Battery (SPPB)).
We prospectively enrolled consecutive outpatients from three tertiary care liver clinics. Frailty was defined by CFS >4. The primary outcome was the composite of unplanned hospitalization or death within 6 months of study entry.
A total of 300 outpatients were enrolled (mean age 57 years, 35% female, 81% white, 66% hepatitis C or alcohol-related liver disease, mean Model for End-Stage Liver Disease (MELD) score 12, 28% with ascites). Overall, 54 (18%) outpatients were frail and 91 (30%) patients had an unplanned hospitalization or death within 6 months. CFS >4 was independently associated with increased rates of unplanned hospitalization or death (57% frail vs. 24% not frail, adjusted odds ratio 3.6; 95% confidence interval (CI): 1.7-7.5; P=0.0008) and there was a dose response (adjusted odds ratio 1.9 per 1-unit increase in CFS, 95% CI: 1.4-2.6; P<0.0001). Models including MELD, ascites, and CFS >4 had a greater discrimination (c-statistic=0.84) than models using FFC or SPPB.
Frailty is strongly and independently associated with an increased risk of unplanned hospitalization or death in outpatients with cirrhosis. The CFS is a rapid screen that could be easily adopted in liver clinics to identify those at highest risk of adverse events.
Hepatocellular carcinoma (HCC) has a high incidence of recurrence following therapy. Therefore, secondary surveillance (scheduled follow-up imaging after treatment) is an important part of disease ...management. The recent approval in the United States for use of a microbubble-based contrast agent for US liver imaging promotes the increased use of contrast-enhanced US (CEUS) in patients with HCC. Although the criteria for the diagnosis of HCC at CEUS are well described, there is a paucity of published literature describing the role of CEUS in ablative therapy and secondary surveillance. In the setting of ablative therapy, CEUS can have vital roles, including patient selection, intraprocedural guidance, and immediate postprocedural assessment. Although CEUS is not widely used, the authors found that it can be used to accurately detect residual or recurrent tumor, characterize the geographic pattern of recurrence (intrazonal, extrazonal, segmental, or remote), and assess for tumor in vein. In addition, similar to primary surveillance, secondary surveillance includes assessment of the entire liver for evaluation of new nodules. Arterial phase hyperenhancement is the reference standard characteristic of disease recurrence at secondary surveillance with CEUS.

Accurate characterization of cirrhotic nodules and early diagnosis of hepatocellular carcinoma (HCC) are of vital importance. Currently, computed tomography (CT) and magnetic resonance (MR) imaging ...are standard modalities for the investigation of new nodules found at surveillance ultrasonography (US). This article describes the successful integration of contrast material-enhanced US into a multimodality approach for diagnosis of HCC and its benefits in this population. The application of contrast-enhanced US immediately following surveillance US allows for prompt dynamic contrast-enhanced evaluation, removing the need for further imaging of benign lesions. Contrast-enhanced US also provides dynamic real-time assessment of tumor vascularity so that contrast enhancement can be identified regardless of its timing or duration, allowing for detection of arterial hypervascularity and portal venous washout. The purely intravascular nature of US contrast agents is valuable as the rapid washout of nonhepatocyte malignancies is highly contributory to their differentiation from HCC. The authors believe contrast-enhanced US provides complementary information to CT and MR imaging in the characterization of nodules in high-risk patients.

Coronavirus disease 2019 (COVID-19) pandemic lockdown and restrictions had significant disruption to patient care. We aimed to evaluate the impact of COVID-19 restrictions on hospitalizations of ...patients with alcoholic and nonalcoholic cirrhosis as well as alcoholic hepatitis (AH) in Alberta, Canada.
We used validated International Classification of Diseases (ICD-9 and ICD-10) coding algorithms to identify liver-related hospitalizations for nonalcoholic cirrhosis, alcoholic cirrhosis, and AH in the province of Alberta between March 2018 and September 2020. We used the provincial inpatient discharge and laboratory databases to identify our cohorts. We used elevated alanine aminotransferase or aspartate aminotransferase, elevated international normalized ratio, or bilirubin to identify AH patients. We compared COVID-19 restrictions (April-September 2020) with prior study periods. Joinpoint regression was used to evaluate the temporal trends among the 3 cohorts.
We identified 2916 hospitalizations for nonalcoholic cirrhosis, 2318 hospitalizations for alcoholic cirrhosis, and 1408 AH hospitalizations during our study time. The in-hospital mortality rate was stable in relation to the pandemic for alcoholic cirrhosis and AH. However, nonalcoholic cirrhosis patients had lower in-hospital mortality rate after March 2020 (8.5% vs 11.5%; P = .033). There was a significant increase in average monthly admissions in the AH cohort (22.1/10,000 admissions during the pandemic vs 11.6/10,000 admissions before March 2020; P < .001).
Before and during COVID-19 monthly admission rates were stable for nonalcoholic and alcoholic cirrhosis; however, there was a significant increase in AH admissions. Because alcohol sales surged during the pandemic, future impact on alcoholic liver disease could be detrimental.
Allocation of donor livers for transplantation in most regions is based on the Model for End-Stage Liver Disease (MELD) or MELD-sodium (MELDNa). Our objective was to assess revisions to MELD and ...MELDNa that include serum albumin for predicting waiting list mortality.
Adults registered for liver transplantation in the United States (2002-2007) were identified from the United Network for Organ Sharing (UNOS) database. Cox regression was used to determine the association between serum albumin and 3-month mortality, and to derive revised MELD and MELDNa scores incorporating albumin ('MELD-albumin' and '5-variable MELD 5vMELD').
Among 40,393 patients, 9% died and 24% underwent transplantation within 3 months of listing. For serum albumin concentrations between 1.0 and 4.0 g/dL, a linear, inverse relationship was observed between albumin and 3-month mortality (adjusted hazard ratio per 1 g/dL reduction in albumin: 1.44; 95% CI 1.35-1.54). The c-statistics for 3-month mortality of MELD-albumin and MELD were 0.913 and 0.896, respectively (P<0.001); 5vMELD was superior to MELDNa (c-statistics 0.922 vs. 0.912, P<0.001). The potential benefit of 5vMELD was greatest in patients with low MELD (<15). Among low MELD patients who died, 27% would have gained ≥10 points with 5vMELD over MELD versus only 4-7% among low MELD survivors and high MELD (≥15) candidates (P<0.0005).
Modification of MELD and MELDNa to include serum albumin is associated with improved prediction of waiting list mortality. If validated and shown to be associated with reduced mortality, adoption of 5vMELD as the basis for liver allograft allocation may improve outcomes on the liver transplant waiting list.
