Assessment of the need for routine intraoperative cell salvage in liver transplantation.

PURPOSE: This study aimed to assess the necessity of routine intraoperative cell salvage in liver transplantations. METHODS: A total of 327 liver transplants performed between 2014 and 2016 was included in the analysis. Patient data, including pre-transplant examinations, intraoperative red blood cell transfusions, and procedural information, were collected. RESULTS: The median age of the patients was 54 years old, with 67% (219) being male. The most prevalent ABO blood type was O, accounting for 48% (155) of cases. The leading causes of liver disease were hepatitis C (113 cases, 34.6%) and alcohol-related liver disease (97 cases, 29.7%). Out of the 327 liver transplants, allogeneic red blood cell transfusions were administered in 110 cases (34%) with a median of two units of red blood cells per case. Cell salvage was employed in 237 transplants (73%), and successful blood recovery was achieved in 221 cases (93%). Among the group that recovered more than 200 mL of blood, the median volume of recovered blood was 417 mL, with no transfusion of allogeneic blood required. A total of 90 transplants was performed without utilizing cell salvage, and, among these cases, 19 required blood transfusions, with a median of zero units transfused. CONCLUSIONS: This study suggests that routine cell salvage is unnecessary for all liver transplantations. The most suitable indication for its use is in patients presenting with portal vein thrombosis and abnormal creatinine levels.

Questionnaire PLD-complaint-specific assessment identifies need for therapy in polycystic liver disease: A multi-centric prospective study.

BACKGROUND AND AIMS: Polycystic liver disease (PLD) can lead to extensive hepatomegaly. Symptom relief is the primary goal of the treatment. The role of the recently developed disease-specific questionnaires for identification of the thresholds and the assessment of therapy needs further investigation. METHODS: A five-year prospective multi-centric observational study in 21 hospitals in Belgium gathered a study population of 198 symptomatic PLD-patients of whom the disease-specific symptom questionnaire PLD-complaint-specific assessment (POLCA) scores were calculated. The thresholds of the POLCA score for the need for volume reduction therapy were analyzed. RESULTS: The study group consisted of mostly (82.8%) women with baseline mean age of 54.4 years ±11.2, median liver volume expressed as height-adjusted total liver volume(htLV) of 1994 mL (interquartile range [IQR] 1275; 3150) and median growth of the liver of +74 mL/year (IQR +3; +230). Volume reduction therapy was needed in 71 patients (35.9%). A POLCA severity score (SPI) ≥ 14 predicted the need for therapy both in the derivation (n = 63) and the validation cohort (n = 126). The thresholds to start somatostatin analogues (n = 55) or to consider liver transplantation (n = 18) were SPI scores of ≥14 and ≥ 18 and the corresponding mean htLVs were 2902 mL (IQR 1908; 3964) and 3607 mL (IQR 2901; 4337), respectively. Somatostatin analogues treatment resulted in a decrease in the SPI score -6.0 versus + 4.5 in patients without somatostatin analogues (p < 0.01). Changes in the SPI score were significantly different between the liver transplantation group and no liver transplantation group, +4.3 ± 7.1 versus -1.6 ± 4.9, respectively, (p < 0.01). CONCLUSION: A polycystic liver disease-specific questionnaire can be used as a guide on when to start a volume reduction therapy and to assess the effect of treatment.

Non-invasive assessment of liver abnormalities in pediatric Fontan patients.

Liver abnormalities are well known among long-term survivors of Fontan palliation, which remains the definite surgery for complex congenital heart disease and single ventricle physiology. Pediatric data however are scarce. We assessed the prevalence and degree of liver abnormalities in pediatric Fontan patients through non-invasive investigations suitable for longitudinal follow-up. Thirty-five patients with a median age of 11.8 years (5.2-16.6) and median time since Fontan of 6 years (1.17-13.83) were studied. Each child underwent a blood test, liver Doppler ultrasound (US), and transient elastography (TE). Healthy children were used as controls for TE measurement. AST, ALT, γGT, and direct bilirubin were abnormal in respectively 12 (34%), 5 (14%), 24 (69%), and 7 (20%) patients, while platelet count was decreased in 7 (20%). Splenomegaly was present in 7 (20%) patients. Portal vein mean flow velocity was < 15 cm/s in 19 (54%) patients indicative of portal hypertension. Twenty-two patients (63%) showed inferior vena cava collapsibility index values below 17%, indicating venous congestion. Hepatic artery and superior mesenteric artery resistance index were inversely correlated with time post Fontan (p < 0.05). TE values in Fontan patients were significantly higher than controls, with a median of 12.6 versus 4.6 kPa (p < 0.001) and were already increased shortly after Fontan completion. Conclusion: Liver abnormalities are frequently observed in pediatric Fontan patients. The non-invasive investigations used were not able to confirm liver fibrosis or differentiate hepatic congestion from fibrosis. Based on our findings, we propose a prospective screening protocol with serial measurements of laboratory, (Doppler) US, and TE parameters. What is Known: • Hepatic dysfunction is a well-known consequence of the Fontan circulation. • The natural history of Fontan-associated liver disease in the pediatric age group remains unclear. What is New: • Liver abnormalities are frequently observed in pediatric Fontan patients; however, differentiating liver fibrosis and hepatic congestion with non-invasive investigations remains challenging. Sonographic Doppler measurements may improve our insight in both Fontan-associated liver disease development and the functioning of the Fontan circulation. • A prospective screening protocol is proposed to improve our ability to detect Fontan-associated liver disease early on and understand its natural history.

Clinical and economic impact of an alert system in primary care for the detection of patients with chronic hepatitis C.

INTRODUCTION: Prevalence of chronic hepatitis C (CHC) is higher in patients born between 1955-1975. The aim was to perform an economic evaluation of an age-based electronic health record (EHR) alert in primary care to detect patients with undiagnosed CHC and its treatment in comparison with non-use of the alert system, in Valencian Community, Spain. MATERIALS AND METHODS: Decision trees and Markov model were used to evaluate the diagnosis and progression of the disease, respectively. CHC was diagnosed by serology and viral load in seropositive subjects. Epidemiological data and diagnostic costs were extracted from public sources of the Valencian Community. Probabilities, utilities and costs of model states were obtained from the literature. The impact on mortality and hepatic complications avoided by the implementation of the alert were estimated, and efficiency was measured as an incremental cost-utility ratio (ICUR) based on quality-adjusted life years (QALYs) and the costs of both alternatives. RESULTS: The EHR alert detected 269,548 patients, of whom 1,331 had CHC (vs. 23 patients with non-alert). Over the patients' lifetime, the alert would prevent 93% of decompensated cirrhosis cases, 87% of hepatocellular carcinomas, 90% of liver transplants, and 89% of liver related deaths compared to non-use of the alert system. In addition, it would obtain an additional 3.3 QALY per patient, with an incremental cost of €10,880 and an ICUR of €3,321. CONCLUSIONS: The implementation of an age-based EHR alert in primary care to detect patients with CHC reduces hepatic complications and mortality and is an efficient strategy.

Assessment of the confidence interval in the multivariable normal tissue complication probability model for predicting radiation-induced liver disease in primary liver cancer.

We developed a confidence interval-(CI) assessing model in multivariable normal tissue complication probability (NTCP) modeling for predicting radiation-induced liver disease (RILD) in primary liver cancer patients using clinical and dosimetric data. Both the mean NTCP and difference in the mean NTCP (ΔNTCP) between two treatment plans of different radiotherapy modalities were further evaluated and their CIs were assessed. Clinical data were retrospectively reviewed in 322 patients with hepatocellular carcinoma (n = 215) and intrahepatic cholangiocarcinoma (n = 107) treated with photon therapy. Dose-volume histograms of normal liver were reduced to mean liver dose (MLD) based on the fraction size-adjusted equivalent uniform dose. The most predictive variables were used to build the model based on multivariable logistic regression analysis with bootstrapping. Internal validation was performed using the cross-validation leave-one-out method. Both the mean NTCP and the mean ΔNTCP with 95% CIs were calculated from computationally generated multivariate random sets of NTCP model parameters using variance-covariance matrix information. RILD occurred in 108/322 patients (33.5%). The NTCP model with three clinical and one dosimetric parameter (tumor type, Child-Pugh class, hepatitis infection status and MLD) was most predictive, with an area under the receiver operative characteristics curve (AUC) of 0.79 (95% CI 0.74-0.84). In eight clinical subgroups based on the three clinical parameters, both the mean NTCP and the mean ΔNTCP with 95% CIs were able to be estimated computationally. The multivariable NTCP model with the assessment of 95% CIs has potential to improve the reliability of the NTCP model-based approach to select the appropriate radiotherapy modality for each patient.

Liver Damage Produced by Malnutrition is Improved by Dietary Supplementation in Mice: Assessment of a Supplement Based on Buriti (A Cerrado Fruit) and Dairy By-products.

BACKGROUND: Malnutrition induced by dietary restriction produces several metabolic changes that affect body weight, the digestive system, and annex organs, including the liver. Malnutrition generates an inflammatory state and increases oxidative stress. The liver is one of the body vital organs, becoming necessary to analyze the impact of food supplementation on the repair of possible changes that may occur in this organ due to malnutrition. AIMS: To evaluate the effects of a low-cost supplementation derived from Buriti and dairy byproducts on liver recovery in malnourished mice, focusing on the expression of oxidative stressrelated genes, as well as biochemical and histological parameters. METHODS: Swiss mice were divided into six groups and submitted to two treatment phases: food restriction, for malnutrition onset; and renutrition, with mice being fed with different diets. RESULTS: Our results indicate that dietary supplementation was successful in recovering liver damage caused by malnutrition in animal models. The new supplement has been shown to recover liver damage with similar or superior results compared to the commercial reference supplement on the market. CONCLUSION: Our work presents a new composition of low cost food supplement based on buriti and dairy by-products, proven to be effective in the malnutrition treatment of malnutrition. The improvements were proven through the recovery of body weight, reduction of inflammation and oxidative stress.

Pretransplantation and Post-Transplantation Liver Disease Assessment in Adolescents Undergoing Isolated Heart Transplantation for Fontan Failure.

OBJECTIVE: To describe the assessment of Fontan-associated liver disease and determine the clinical and imaging measures that may identify hepatic morbidity risk in isolated heart transplantation candidates and trend those measures post-isolated heart transplantation. STUDY DESIGN: Retrospective analysis of pre-isolated heart transplantation and post-isolated heart transplantation Fontan-associated liver disease (FALD) status using blood tests, magnetic resonance imaging (MRI), and liver biopsy analysis within 6 months before isolated heart transplantation and 12 months after isolated heart transplantation in 9 consecutive patients with Fontan. Pre- and post-isolated heart transplantation standard laboratory values; varices, ascites, splenomegaly, thrombocytopenia (VAST) score; Fontan liver MRI score; liver biopsy scores; Model for End-stage Liver Disease (MELD); MELD excluding the International Normalized Ratio (MELD-XI); AST to platelet ratio index, and cardiac catheterization data were compared. RESULTS: Pretransplantation maximum MELD and MELD-XI was 15 and 16, respectively. Central venous pressures and VAST scores decreased significantly post-transplantation. In 5 paired studies, Fontan liver MRI score maximum was 10 pretransplantation and decreased significantly post-transplantation. Arterially enhancing nodules on MRI persisted in 2 patients post-transplantation. Pretransplantation and post-transplantation liver biopsy scores did not differ in 4 paired biopsy specimens. CONCLUSIONS: Patients with FALD and MELD <15, MELD-XI <16, Fontan liver MRI score <10, and VAST score ≤2 can have successful short-term isolated heart transplantation outcomes. Liver MRI and VAST scores improved post-transplantation. Post-transplantation liver biopsy scores did not change significantly. Pretransplantation liver biopsy demonstrating fibrosis alone should not exclude consideration of isolated heart transplantation. The persistence of hepatic vascular remodeling and fibrosis post-isolated heart transplantation suggests that continued surveillance for hepatic complications post-transplantation for patients with Fontan is reasonable.

Polypharmacy is a risk factor for mortality, severe chronic kidney disease, and liver disease among privately insured adults with cerebral palsy.

BACKGROUND: Adults with cerebral palsy (CP) have an increased risk for polypharmacy, premature mortality, and early development of several morbidities, including conditions associated with excess medication exposure, such as chronic kidney disease (CKD) and liver disease. To date, very little is known about the consequence of polypharmacy for adults with CP. OBJECTIVE: To determine if polypharmacy is associated with an increased risk for mortality, severe CKD, and liver disease among adults with CP, before and after adjusting for comorbid neurodevelopmental disabilities (NDDs) and multimorbidity. METHODS: This is an exploratory treatment effectiveness study. Data from the Optum Clinformatics Data Mart were used for this retrospective cohort study. Adults aged 18 years or older with a diagnosis of CP and without severe CKD (stages IV+) and liver disease were identified from the calendar year 2013 and were subsequently followed from January 1, 2014, to death, severe CKD, liver disease, loss to follow-up, or end of study period (December 31, 2017). Diagnosis codes were used to identify NDDs (intellectual disabilities, epilepsy, autism spectrum disorders, spina bifida) and 24 relevant morbidities at baseline (i.e., calendar year 2013). Polypharmacy was defined as ≥ 5 medications and hyperpolypharmacy was defined as ≥ 10 medications at baseline. Cox regression models were developed to examine the association (as HR and 95% CI) between polypharmacy and hyperpolypharmacy with mortality, severe CKD, and liver disease separately, before and after adjusting for covariates (demographics, NDDs, multimorbidity). Exploratory analyses examined the mediating effect of incident severe CKD or liver disease on the association between the exposure (polypharmacy or hyperpolypharmacy) on outcomes. RESULTS: Of the 9,238 adults with CP, 58.5% had polypharmacy and 29.5% had hyperpolypharmacy. The fully adjusted HR for mortality was 2.14 (95% CI = 1.59-2.89) for polypharmacy and 1.65 (95% CI = 1.31-2.09) for hyperpolypharmacy. The fully adjusted HR for severe CKD was 1.66 (95% CI = 1.17-2.36) for polypharmacy and 1.67 (95% CI = 1.27-2.19) for hyperpolypharmacy. The fully adjusted HR for liver disease was 1.57 (95% CI = 1.27-1.94) for polypharmacy and 1.72 (95% CI = 1.42-2.08) for hyperpolypharmacy. Incident liver disease mediated 5.37% (polypharmacy) and 7.54% (hyperpolypharmacy) of the association between the exposure with incident severe CKD for nonelderly (aged < 65 years), while incident severe CKD mediated 7.05% (polypharmacy) and 6.64% (hyperpolypharmacy) of the association between the exposure with incident liver disease for elderly (aged ≥ 65 years). CONCLUSIONS: Polypharmacy and hyperpolypharmacy are robust risk factors for risk of mortality, severe CKD, and liver disease among privately insured adults with CP. While incidence of severe CKD and liver disease had negligible effects on the association between polypharmacy with mortality, there is evidence that they mediate a considerable portion of one another and require further examination.

THE ASSESSMENT OF COMORBID PATHOLOGY IN CLEAN-UP WORKERS OF THE ACCIDENT CONSEQUENCES AT THE CHORNOBYL NPP HAVING CARDIOVASCULAR DISEASES. / OTsINKA KOMORBIDNOÏ PATOLOGIÏ V UChASNYKIV LIKVIDATsIÏ NASLIDKIV AVARIÏ NA ChORNOBYL'S'KII AES Z ZAKhVORIuVANNIaMY SERTsEVO-SUDYNNOÏ SYSTEMY.

OBJECTIVE: Analysis of comorbid pathology based on the use of methods for its quantitative assessment in personswho were exposed to radiation because of the Chornobyl accident. MATERIALS AND METHODS: Comorbid pathology was studied in 608 men, including 420 clean-up workers (CW) of theaccident consequences at the Chornobyl NPP (main group) and 188 non-irradiated persons (control group - CG). Allpatients had cardiovascular diseases as their main pathology and were examined in the cardiology department ofthe NRCRM hospital during 2011-2019. The groups did not differ by age, either at the beginning of the accident orat the time of their last examination. Patients of both groups before the accident were practically healthy peopleand were not registered at the dispensary. The Cumulative Illness Rating Scale (CIRS) was used to quantify comorbid pathology. RESULTS: Comorbid pathology was detected in 418 CW (99.5 %) and 183 patients of CG (99.3 %). The total score inCW (10.3 ± 2.9) units significantly (р = 0.000) exceeded the same index in non-irradiated patients (8.8 ± 3.0) units,as well as the mean number of CIRS categories, whose level severity was 1 point (3.3 ± 1.7 vs. 2.6 ± 1.5, р = 0.000),2 points (1.8 ± 1.0 vs. 1.6 ± 1.0, p = 0.032) and 3-4 points (1.2 ± 0.8 vs. 1.0 ± 0.9, р = 0.062). In contrast, the meanvalue of the categories with zero score, i.e. without diseases, was more common in CG (7.8 ± 1.8 vs. 8.8 ± 1.7,р = 0.000). The most common pathology in CW and CG were heart (98.3 % vs. 94.7 %, р < 0.05) and vascular diseases(92.9 % vs. 87.8 %, р > 0.05), followed by diseases of nervous system (79.0 % vs. 57.4 %, р <0.001), musculoskeletal system and skin (69.8 % vs. 56.9 %, р < 0.01), endocrine (56.0 % vs. 49,5 %, р > 0.05) and the respiratory system (53.8 % vs. 53.7 %, р > 0.05) and liver (51.2 % vs. 36.2 %, р < 0.001), which were detected more than in halfpatients of the main group. Diseases of the kidneys (3.3 % vs. 4.8 %, р > 0.05) and lower gastrointestinal tract(3.3 % vs. 0.5 %, р < 0.01) were quite rare. The incidence of the other four CIRS categories was 18.6-34 %. The totalscore in subgroups with different ages varied in descending order of mean values as follows: CW > 65 years (10.5 ± 2.9)units, CW < 65 years (9.9 ± 2.8) units, CG > 65 years (9.5 ± 2.8) units and CG < 65 years (7.8 ± 2.9) units with significant differences both between age subgroups in each of the groups and between CW and CG older subgroups. CONCLUSIONS: Quantitative assessment of comorbidity by CIRS showed that in persons irradiated during their emergency work due to the Chornobyl accident, the incidence of combined pathology of such organ systems as cardiovascular, nervous, endocrine, hematopoietic, urogenital, musculoskeletal, gastrointestinal, liver and kidneys wassignificantly higher than in non-irradiated patients. In irradiated patients, the course of comorbid pathology wasmore severe for each system and in general, reflecting higher values of the total CIRS score. Both among CW andnon-irradiated controls, higher values of the total comorbidity score were observed in patients 65 years and older,compared with younger individuals. In both age subgroups of CW the total score was higher than in patients of thecontrol group.

Alcohol and the Hospitalized Patient.

Alcohol use is a common social and recreational activity in our society. Misuse of alcohol can lead to significant medical comorbidities that can affect essentially every organ system and lead to high health care costs and utilization. Heavy alcohol use across the spectrum from binge drinking and intoxication to chronic alcohol use disorder can lead to high morbidity and mortality both in the long and short term. Recognizing and treating common neurologic, gastrointestinal, and hematological manifestations of excess alcohol intake are essential for those who care for hospitalized patients. Withdrawal is among the most common and dangerous sequela associated with alcohol use disorder.

Epidemiology: Pathogenesis, and Diagnostic Strategy of Diabetic Liver Disease in Japan.

Type 2 diabetes (T2D) is closely associated with nonalcoholic fatty liver disease (NAFLD). Nonalcoholic steatohepatitis (NASH), a severe form of NAFLD, can lead to cirrhosis, hepatocellular carcinoma (HCC), and hepatic decompensation. Patients with T2D have twice the risk of HCC incidence compared with those without T2D. Because the hepatic fibrosis grade is the main determinant of mortality in patients with NAFLD, identifying patients with advanced fibrosis using non-invasive tests (NITs) or imaging modalities is crucial. Globally, the fibrosis-4 index (FIB-4 index), NAFLD fibrosis score, and enhanced liver fibrosis test have been established to evaluate hepatic fibrosis. Two-step algorithms using FIB-4 index as first triaging tool are globally accepted. It remains unknown which kinds of NITs or elastography are best as the second step tool. In Japan, type IV collagen 7s or the CA-fibrosis index (comprising type IV collagen 7s and aspartate aminotransferase (AST)) is believed to precisely predict advanced fibrosis in NAFLD. Patients with NAFLD who have high non-invasive test results should be screened for HCC or esophageal varices. Risk factors of rapid fibrosis progression in NAFLD includes age, severe obesity, presence of T2D, menopause in women, and a patatin-like phospholipase domain containing the 3 GG genotype. Patients with NAFLD who have these risk factors should be intensively treated with lifestyle modification or pharmacotherapies for preventing liver-related mortality.

The Enhanced Liver Fibrosis test is associated with liver-related outcomes in postmenopausal women with risk factors for liver disease.

BACKGROUND: Chronic liver disease (CLD) is usually asymptomatic but earlier detection is critical to permit life-saving interventions for those at risk due to high alcohol consumption and increased body mass index (BMI). The aim of this study was to estimate the association between the Enhanced Liver Fibrosis (ELF) test and liver-related events (LRE) and its performance in predicting LRE in postmenopausal women with risk factors in a nested case-control study within the United Kingdom Trial of Ovarian Cancer Screening (UKCTOCS). METHODS: In a cohort of 95,126 we performed a case-control study measuring ELF in blinded samples from 173 participants with self-reported high alcohol use and / or BMI ≥25 kg/m2 comprising all 58 cases who developed LRE and 115 controls matched for age, alcohol and BMI who did not develop LRE during median follow-up of 8.5 years. RESULTS: Using Cox regression at an ELF threshold of 10.51 hazard ratios (HR) for LRE were 4.88 (95% confidence interval (CI) 2.37-10.03) (unadjusted model) and 4.62 (95% CI 2.12-10.08) (adjusted for deprivation and self-reported hypertension, heart disease, hypercholesterolaemia and diabetes). At a threshold of 9.8 HR for LRE were 2.21 (95% CI 1.22-3.97) (unadjusted model) and 2.18 (95% CI 1.19-4.01) (adjusted). ELF was evaluated as a time dependent variable by generating time-dependent Cox models; HRs at an ELF threshold of 10.51 were 1.94 (95% CI 1.10-3.39) (unadjusted) and 2.05 (95% CI 1.16-3.64) (adjusted) and at a threshold of 9.8 HRs were 1.85 (95% CI 1.09-3.15) (unadjusted) and 1.80 (95% CI 1.04-3.13) (adjusted). Area under the receiver operating characteristic curve for recruitment ELF predicting LRE was 0.58 (95% CI 0.49-0.68), and for second subsequent ELF 0.61 (95% CI 0.52-0.71). CONCLUSION: This study demonstrates the association between ELF and CLD in postmenopausal women with risk factors for liver disease, creating the opportunity to intervene to reduce liver-related mortality and morbidity. Although larger studies are required, these results demonstrate the potential of ELF as a prognostic tool in health checks in primary care. TRIAL REGISTRATION: This study is nested in UKCTOCS. UKCTOCS is registered as an International Standard Randomised Controlled Trial, number ISRCTN22488978. Registered 06/04/2000.

Burden of Cirrhosis and Other Chronic Liver Diseases Caused by Specific Etiologies in China, 1990-2016: Findings from the Global Burden of Disease Study 2016.

OBJECTIVE: To estimate the burden of cirrhosis and other chronic liver diseases caused by specific etiologies in China. METHODS: Data from the Global Burden of Disease Study 2016 (GBD 2016) were used. We evaluated the burden by analyzing age-sex-province-specific prevalence, mortality, and disability-adjusted life-years (DALYs) of 33 provinces in China. RESULTS: From 1990 to 2016, prevalence cases in thousands increased by 73.7% from 6833.3 (95% UI: 6498.0-7180.6) to 11869.6 (95% UI: 11274.6-12504.7). Age-standardized mortality and DALY rates per 100,000 decreased by 51.2% and 53.3%, respectively. Male and elderly people (aged ≥ 60 years) preponderance were found for prevalence, mortality, and DALYs. The number of prevalence cases, deaths, and DALYs due to hepatitis C virus (HCV) increased by 86.6%, 8.7%, and 0.9%, respectively. Also, age-standardized prevalence rates decreased in 31 provinces, but increased in Yunnan and Shandong. The Socio-demographic Index (SDI) values were negatively correlated with age-standardized mortality and DALY rates by provinces in 2016; the correlation coefficients were -0.817 and -0.828, respectively. CONCLUSION: Cirrhosis and other chronic liver diseases remain a huge health burden in China, with the increase of population and the aging of population. Hepatitis B virus (HBV) remains the leading cause of the health burden in China.

Advanced liver function assessment in patients with intestinal failure on long-term parenteral nutrition.

BACKGROUND & AIMS: Intestinal failure associated liver disease (IFALD) is one of the leading complications and causes of deaths in adult patients receiving home parenteral nutrition for chronic intestinal failure (CIF). Early diagnosis of IFALD is key to alleviate the progression of hepatic dysfunction. The aim of this study was to evaluate the capability of noninvasive liver function tests. METHODS: 90 adult patients with CIF receiving long-term home parenteral nutrition were included in a prospective cross-sectional study at our department between 2014 and 2017. All participants underwent dynamic liver function assessment (maximum liver function capacity [LiMAx] test, indocyanine green [ICG] test), transient elastography (FibroScan), blood tests and comprehensive nutritional status assessment. Univariate and multivariable analysis were performed to identify predictors of liver function. RESULTS: LiMAx, ICG test, and FibroScan highly correlated with standard liver function tests. Multivariable analysis identified intact ileum (B = 520.895; p = 0.010), digestive anatomy type 3 (B = 75.612; p = 0.025), citrulline level (B = 3.428; p = 0.040), parenteral olive oil intake (B = -0.570; p = 0.043), and oral intake (B = 182.227; p = 0.040) as independent risk factors affecting liver function determined by LiMAx test. ICG test and FibroScan showed no correlation with gastrointestinal and nutrition-related parameters. CONCLUSION: The LiMAx test is significantly associated with widely accepted risk factors for IFALD by multivariable analysis, whereas ICG test and FibroScan failed to show significant correlations. Liver function assessment by LiMAx test may therefore have the potential to detect alterations in liver function and identify patients at risk for the development of IFALD. Longitudinal studies are needed to investigate the impact of liver function determined by LiMAx test on long-term outcome in patients with CIF.

Liver Strain Using Feature Tracking of Cine Cardiac Magnetic Resonance Imaging: Assessment of Liver Dysfunction in Patients with Fontan Circulation and Tetralogy of Fallot.

We propose a novel method to quantify pulsatile liver deformation using the feature tracking method of cardiac cine magnetic resonance imaging (MRI) and investigate its association with liver dysfunction in long-term postoperative patients after Fontan and intracardiac repair for the tetralogy of Fallot (TOF). Standard cine MRI which was previously performed for cardiac evaluation of 85 patients who underwent Fontan operation (mean age, 22.9 years), 43 patients with TOF (mean age, 34.6 years), and 32 healthy controls (mean age, 42.3 years) were retrospectively analyzed. Pulsatile liver deformation in the craniocaudal direction was calculated using the feature tracking method of cardiac cine imaging derived from cine-balanced turbo field-echo sequences performed on a 1.5 Tesla MR scanner, and was defined as liver strain. The liver strain was compared across the three patient groups using one-way analysis of variance. Liver dysfunction by a liver strain were compared using the Mann-Whitney U test. Liver strain for patients who underwent Fontan operation and TOF patients was significantly lower than controls (Fontan, 13.3 ± 6.5%; TOF, 15.0 ± 11.2%; controls, 23.1 ± 10.2%, p < 0.0001). In Fontan and TOF patients, MELD score was significantly greater for patients with a liver strain < 15% than those with values > 15% (5.9 ± 5.8 vs. 2.9 ± 2.9, p < 0.001). Lower liver strain values were found in adolescent and adult patients after Fontan operation and TOF, and correlates with the severity of liver injury, expressed as MELD score. Our method can evaluate hepatic function in adult congenital heart disease, together with the assessment of cardiac function.

Unacceptable failures: the final report of the Lancet Commission into liver disease in the UK.

This final report of the Lancet Commission into liver disease in the UK stresses the continuing increase in burden of liver disease from excess alcohol consumption and obesity, with high levels of hospital admissions which are worsening in deprived areas. Only with comprehensive food and alcohol strategies based on fiscal and regulatory measures (including a minimum unit price for alcohol, the alcohol duty escalator, and an extension of the sugar levy on food content) can the disease burden be curtailed. Following introduction of minimum unit pricing in Scotland, alcohol sales fell by 3%, with the greatest effect on heavy drinkers of low-cost alcohol products. We also discuss the major contribution of obesity and alcohol to the ten most common cancers as well as measures outlined by the departing Chief Medical Officer to combat rising levels of obesity-the highest of any country in the west. Mortality of severely ill patients with liver disease in district general hospitals is unacceptably high, indicating the need to develop a masterplan for improving hospital care. We propose a plan based around specialist hospital centres that are linked to district general hospitals by operational delivery networks. This plan has received strong backing from the British Association for Study of the Liver and British Society of Gastroenterology, but is held up at NHS England. The value of so-called day-case care bundles to reduce high hospital readmission rates with greater care in the community is described, along with examples of locally derived schemes for the early detection of disease and, in particular, schemes to allow general practitioners to refer patients directly for elastography assessment. New funding arrangements for general practitioners will be required if these proposals are to be taken up more widely around the country. Understanding of the harm to health from lifestyle causes among the general population is low, with a poor knowledge of alcohol consumption and dietary guidelines. The Lancet Commission has serious doubts about whether the initiatives described in the Prevention Green Paper, with the onus placed on the individual based on the use of information technology and the latest in behavioural science, will be effective. We call for greater coordination between official and non-official bodies that have highlighted the unacceptable disease burden from liver disease in England in order to present a single, strong voice to the higher echelons of government.

Initial assessment and ongoing monitoring of lysosomal acid lipase deficiency in children and adults: Consensus recommendations from an international collaborative working group.

BACKGROUND: Lysosomal acid lipase (LAL) deficiency is an ultra-rare, progressive, autosomal recessive disorder. Functional mutations in LIPA, the gene that encodes LAL, result in accumulation of cholesteryl esters and triglycerides in hepatocytes and in the macrophages of the intestines, vascular endothelial system, and numerous other organs. LAL deficiency has a broad clinical spectrum; children and adults can present with dyslipidemia, liver enzyme elevations, hepatosplenomegaly, hepatic steatosis, liver fibrosis and/or cirrhosis, and vascular disease, which may lead to significant morbidity and premature mortality in some patients. Given the systemic involvement and the wide range of healthcare specialists who manage patients with LAL deficiency, there is a need for guidelines to assess and monitor disease involvement. OBJECTIVES: To provide a set of recommendations for the initial assessment and ongoing monitoring of patients with LAL deficiency to help physicians in various disciplines effectively manage the disease based on the observed presentation and progression in each case. METHODS: A group of internationally recognized healthcare specialists with expertise in clinical genetics, pathology, hepatology, gastroenterology, cardiology, and lipidology convened to develop an evidence-based consensus of best practices for the initial assessment and ongoing monitoring of children and adults with LAL deficiency, regardless of treatment status; infants with LAL deficiency have been excluded from these guidelines because they require specialized care. RESULTS: The authors present guidance for the assessment and monitoring of patients with LAL deficiency based on age and disease manifestations that include the hepatic, cardiovascular, and gastrointestinal systems. A schedule for ongoing monitoring of disease progression is provided. In addition, the need to establish an interdisciplinary and integrated care team to optimize the approach to managing this systemic disease is highlighted. CONCLUSIONS: There is currently no published guidance on the assessment and monitoring of patients with LAL deficiency. These consensus recommendations for the initial assessment and ongoing monitoring of children and adults with LAL deficiency are intended to help improve the management of these patients.

Noninvasive assessment of liver status in adult patients after the Fontan procedure.

INTRODUCTION A hemodynamic derangement in Fontan circulation causes liver pathology known as Fontan­­associated liver disease. Although liver biopsy is a standard for diagnosis of liver fibrosis, noninvasive methods are being developed, including shear wave elastography (SWE). OBJECTIVES We aimed to evaluate the degree of liver stiffness (LS) using SWE in patients with Fontan circulation in a long­­term follow­­up and to investigate a relationship between patient characteristics and LS. PATIENTS AND METHODS The study included 59 patients after the Fontan procedure. Clinical examinations and laboratory tests were performed. According to the stage of LS, patients were divided into 2 subgroups: group 1 (METAVIR stages F1 and F2) and group 2 (METAVIR stages F3 and F4). The ratio of aspartate transaminase to alanine transaminase, aspartate transaminase­­to­­platelet ratio index (APRI), fibrosis­­4 (FIB­­4) score, and Forns index were assessed. RESULTS The median LS was 9.1 kPa (interquartile range, 3.9-18.5 kPa). Five patients (9%) demonstrated LS in stage F1; 14 (26%), F2; 28 (52%), F3; and 7 (13%), F4. Group 2 had significantly higher aspartate transaminase and γ­­glutamyltranspeptidase levels, APRI, FIB­­4, and Forns index, and lower platelet count than group 1. A canonical correlation analysis indicated that LS and thrombocytopenia were related to time from the Fontan procedure, age at procedure, and single ventricular ejection fraction. CONCLUSIONS We showed that adult patients after the Fontan procedure develop liver dysfunction. Time from surgery, age at procedure, and single ventricular ejection fraction are related to the degree of LS assessed by SWE. Finally, SWE, APRI, Forns index, and FIB­4 score may help assess the degree of liver fibrosis.
