Spectrum of Autoimmune Liver Disease and Real-World Treatment Experience from a Tertiary Care Hospital. J Clin Exp Hepatol 2023; 13:241-251. [PMID: 36950480 PMCID: PMC10025584 DOI: 10.1016/j.jceh.2022.11.002] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 06/20/2022] [Accepted: 11/01/2022] [Indexed: 11/12/2022] Open
Abstract
Background and aims Autoimmune liver disease (AILD) comprises of autoimmune hepatitis (AIH), primary biliary cholangitis (PBC) and primary sclerosing cholangitis (PSC) with a spectrum of overlap amongst the three. We analyzed the spectrum and treatment outcomes of patients with AILD presenting to a tertiary care center in India. Methods A retrospective analysis of AILD patients from June 2008 to April 2021 was performed. The diagnosis was based on clinical, biochemical, imaging, serological, and histological characteristics. Eligible patients received treatment depending on the disease stage. Biochemical response to treatment was defined as normalization of AST, ALT, bilirubin, and immunoglobulin G levels at 6 months in AIH, normalization of total bilirubin and/or albumin at 1 year in PBC and decrease in alkaline phosphatase (ALP) levels by 40% in PSC. Results Two hundred seventy-five patients were analyzed. AIH (58.54%) was most common, followed by an overlap of AIH-PBC (24%) and AIH-PSC (6.54%), PSC (6.18%), and PBC (4.72%). Most patients presented in 3rd or 4th decade, except PBC which occurred predominantly in 5th decade. The majority of patients were females (72.72%). Jaundice was the most common presentation seen in 60% of patients. Cirrhosis was present in 57.47% of patients. Patients with overlap had more pruritus (54.76 vs 6.83%), fatigue (63.1% vs 49.7%), hepatomegaly (52.4% vs 25.5%), and higher ALP (80.9% vs 37.7%) than patients with AIH alone. Acute presentation was seen in 33 patients (13.5%) with most having AIH flare. Five patients had acute liver failure (ALF) and 9 had acute-on-chronic liver failure (ACLF). ALF was associated with 80% mortality while 55.56% of patients with ACLF had a complete biochemical response to immunosuppression. Among patients with AIH and/or overlap who received immunosuppression, a complete biochemical response to immunosuppression was seen in 60.69% of patients. High ALT (OR 1.001 [1.000-1.003], P = 0.034), high albumin (OR 1.91 [1.05-3.48], P = 0.034) and low fibrosis on biopsy (OR 0.54 [0.33-0.91], P = 0.020) predicted complete response. Conclusion AIH is the most common AILD followed by overlap syndromes, PSC and PBC in our cohort. Biochemical response to immunosuppression is seen in 60% of patients with AIH & low fibrosis score on histopathology predicts a complete response.

Study of Adherence to Medication in Pediatric Liver Diseases ("SAMPLD" Study) in Indian Children. J Clin Exp Hepatol 2023; 13:22-30. [PMID: 36647409 PMCID: PMC9840084 DOI: 10.1016/j.jceh.2022.10.006] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 07/09/2022] [Accepted: 10/11/2022] [Indexed: 11/05/2022] Open
Abstract
Background/objectives Adherence to medication(s) is an essential component of holistic management in any chronic disease including in post liver transplant (LT) patients. Thus, this study aimed to assess adherence to medications in Indian pediatric liver disease patients (including post LT recipients) and to identify variables affecting its occurrence. Methods A cross-sectional study was conducted among pediatric (<18 years of age) subjects with Wilson disease (WD) and autoimmune liver disease (AILD) along with post LT recipients from May 2021 to October 2021. Structured tools using prevalidated questionnaires (Medication adherence measure and the Child & Adolescent Adherence to Medication Questionnaire) were used to collect data related to nonadherence prevalence (based on missed and late doses) and factors influencing the adherence. Results A total of 152 children were included in the study (WD 39.5%, AILD 32.9%, and post LT 27.6%). Prevalence of missed and late dose nonadherence (at a cut-off of ≥20%) was 12.5% and 16.4%, respectively. Older age (odd's ratio/O.R 1.185), stay in a rural area (O.R 5.08), and barriers like bad taste of medication (O.R 4.728) and hard to remember the medication (O.R 7.180) were independently associated with nonadherence (P < 0.05). Conclusions Overall, nonadherence was seen in 12-16%, i.e., around one-sixth of the patients, with least nonadherence seen in post LT recipients (0-2.4%). Older age of the patient, rural place of stay and personal barriers like hard to remember/forgetfulness and bad medication taste were identified as factors independently leading to nonadherence.

Long-Term Improvement in Liver Function Following Transjugular Intrahepatic Portosystemic Shunt in Patients With Budd-Chiari Syndrome. J Clin Exp Hepatol 2022; 12:1474-1479. [PMID: 36340317 PMCID: PMC9630014 DOI: 10.1016/j.jceh.2022.07.251] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/24/2022] [Accepted: 07/23/2022] [Indexed: 12/12/2022] Open
Abstract
Background Transjugular intrahepatic portosystemic shunt (TIPS) relieves hepatic venous obstruction in Budd-Chiari syndrome (BCS), but the effect on liver function is unclear, particularly outside the immediate post-treatment period. This study aims to evaluate the long-term impact of TIPS on liver function and outcomes in BCS patients. Methods Twenty patients with BCS who underwent TIPS from 1999 to 2018 were included. Demographic data and clinical data at the time of TIPS procedure, 6 months, 12 months, 2 years, 5 years, and 10 years post-TIPS were collected. Results There were 13 (13/20, 65%) women and 7 (7/20, 35%) men with a mean age at the time of TIPS of 42.6 ± 12.8 years. The median time from BCS diagnosis to TIPS was 41 (IQR: 4-165) days. The number of patients with severe ascites decreased significantly from 10/17 (58.8%) at the time of TIPS, to 1/16 (7.7%), 1/13 (7.7%), 2/16 (12.5%), 1/14 (7.1%), and 0/8 (0%) at 6 months, 12 months, 2 years, 5 years and 10 years post-TIPS, respectively. 4/20 (20%) patients developed new hepatic encephalopathy post-TIPS procedure. Child-Pugh score significantly decreased from a score of 9.4 ± 1.8 pre-TIPS to 7.6 ± 1.8 at 6 months, 7.4 ± 1.5 at 12 months, 7.3 ± 1.6 at 2 years, 6.8 ± 1.5 at 5 years, and 6.4 ± 0.7 at 10 years post-TIPS. Fifteen (15/20, 75%) patients required TIPS revision including 4 (4/15, 26.7%) within 30 days, 2 (2/15, 13.3% within 1 month to 1 year, and 9 (9/15, 60%) at more than 1 year. Eight (8/20, 40%) patients underwent liver transplantation (LT) at median time of 7.3 (IQR 3.2-12.9) years after TIPS. Conclusion TIPS placement for BCS results in sustained resolution of symptoms and improved liver function. Despite the frequent need for revisions, the long-term durability of TIPS can forgo the need for LT in the majority of patients.

Abstract
Background : Since its declaration as a global pandemic on March11th 2020, COVID-19 has had a significant effect on solid-organ transplantation. The aim of this study was to analyze the impact of COVID-19 on Liver transplantation (LT) in United States. Methods : We retrospectively analyzed the United Network for Organ Sharing database regarding characteristics of donors, adult-LT recipients, and transplant outcomes during early-COVID period (March 11- September 11, 2020) and compared them to pre-COVID period (March 11 - September 11, 2019). Results : Overall, 4% fewer LTs were performed during early-COVID period (4107 vs 4277). Compared to pre-COVID period, transplants performed in early-COVID period were associated with: increase in alcoholic liver disease as most common primary diagnosis (1315 vs 1187, P< 0.01), higher MELD score in the recipients (25 vs 23, P<0.01), lower time on wait-list (52 vs 84 days, P<0.01), higher need for hemodialysis at transplant (9.4 vs 11.1%, P=0.012), longer distance from recipient hospital (131 vs 64 miles, P<0.01) and higher donor risk index (1.65 vs 1.55, P<0.01). Early-COVID period saw increase in rejection episodes before discharge (4.6 vs 3.4%, P=0.023) and lower 90-day graft/patient survival (90.2 vs 95.1 %, P<0.01; 92.2 vs 96.5 %, P<0.01). In multivariable cox-regression analysis, early-COVID period was the independent risk factor for graft failure at 90-days post-transplant (Hazard Ratio 1.77, P<0.01). Conclusions : During early-COVID period in United States, overall LT decreased, alcoholic liver disease was primary diagnosis for LT, rate of rejection episodes before discharge was higher and 90-days post-transplant graft survival was lower.

Abstract
Liver tumours are uncommon in the paediatric population, constituting 1-2 % of all paediatric tumours and 4% of all paediatric liver tumours. Hepatoblastoma followed by hepatocellular carcinoma is the most common tumours in this age group. Simultaneous development of two discrete liver tumours of distinct histologies (collision tumour) has been occasionally reported in adults but never in children. We hereby present the first reported case of hepatic collision tumours (hepatocellular carcinoma and cholangiocarcinoma) in the explant liver of a child who underwent living donor liver transplantation for end-stage liver disease and severe hepatopulmonary syndrome. The manuscript describes the clinical, radiological and histopathological findings of this case and also highlights the dilemma associated with management of this case had the diagnosis been made in the preoperative setting and also about the proposed management plan for this case in the postoperative period.

Abstract
The clinical course after liver transplantation (LT) in progressive familial intrahepatic cholestasis type 1 (PFIC1) is complicated by intractable diarrhoea, growth failure, graft steatosis and cirrhosis. Recent evidence from Japan suggests the role of genotype to predict outcome after LT. We report a case with pathogenic frameshift mutation who had failed partial external biliary diversion, underwent LT and his post-LT course has been complicated by intractable diarrhoea, growth failure, steatosis and fibrosis. This case highlights the fact that homozygous frameshift p.Gly197LeufsTer10 mutation in ATP8B1 is associated with poor outcome and genetic evaluation should be mandatory before subjecting the patient to LT.

Abstract
Patients with cirrhosis of the liver are at high risk of developing portal vein thrombosis (PVT), which has a complex, multifactorial cause. The condition may present with a myriad of symptoms and can occasionally cause severe complications. Contrast-enhanced computed tomography (CT) is the gold standard for the diagnosis of PVT. There are uncertainties regarding the effect on PVT and its treatment outcome in patients with cirrhosis. The main challenge for managing PVT in cirrhosis is analyzing the risk of hemorrhage compared to the risk of thrombus extension leading to complications. All current knowledge regarding non-tumor PVT in cirrhosis, including epidemiology, risk factors, classification, clinical presentation, diagnosis, impact on natural history, and treatment, is discussed in the present article.

Abstract
BACKGROUND Cirrhotic cardiomyopathy refers to the structural and functional changes in the heart leading to either impaired systolic, diastolic, electrocardiographic, and neurohormonal changes associated with cirrhosis and portal hypertension. Cirrhotic cardiomyopathy is present in 50% of patients with cirrhosis and is clinically seen as impaired contractility, diastolic dysfunction, hyperdynamic circulation, and electromechanical desynchrony such as QT prolongation. In this review, we will discuss the cardiac physiology principles underlying cirrhotic cardiomyopathy, imaging techniques such as cardiac magnetic resonance imaging and scintigraphy, cardiac biomarkers, and newer echocardiographic techniques such as tissue Doppler imaging and speckle tracking, and emerging treatments to improve outcomes. METHODS We reviewed available literature from MEDLINE for randomized controlled trials, cohort studies, cross-sectional studies, and real-world outcomes using the search terms "cirrhotic cardiomyopathy," "left ventricular diastolic dysfunction," "heart failure in cirrhosis," "liver transplantation," and "coronary artery disease". RESULTS Cirrhotic cardiomyopathy is associated with increased risk of complications such as hepatorenal syndrome, refractory ascites, impaired response to stressors including sepsis, bleeding or transplantation, poor health-related quality of life and increased morbidity and mortality. The evaluation of cirrhotic cardiomyopathy should also guide the feasibility of procedures such as transjugular intrahepatic portosystemic shunt, dose titration protocol of betablockers, and liver transplantation. The use of targeted heart rate reduction is of interest to improve cardiac filling and improve the cardiac output using repurposed heart failure drugs such as ivabradine. Liver transplantation may also reverse the cirrhotic cardiomyopathy; however, careful cardiac evaluation is necessary to rule out coronary artery disease and improve cardiac outcomes in the perioperative period. CONCLUSION More data are needed on the new diagnostic criteria, molecular and biochemical changes, and repurposed drugs in cirrhotic cardiomyopathy. The use of advanced imaging techniques should be incorporated in clinical practice.

Abstract
Patients with chronic liver disease (CLD) with or without cirrhosis remain at risk of developing hepatic decompensation when infected with viral or bacterial pathogens. The Advisory Committee on Immunization Practices (ACIP) currently recommends vaccination in CLD against hepatitis A virus (HAV), hepatitis B virus (HBV), influenza, pneumococcus, herpes zoster, tetanus, diphtheria, pertussis, and SARS-CoV-2. Inactivated vaccines are preferred over live attenuated ones, especially in transplant recipients where live vaccines are contraindicated. As the severity of the liver disease progresses, vaccine efficacy declines, and therefore, vaccines should be ideally administered early in the disease course for optimal immune response. Despite the strong recommendations, overall vaccination coverage in CLD remains poor; however, it is encouraging to note that in recent years coverage against influenza and pneumococcus has shown some improvement. Inadequate access to healthcare, lack of information on vaccine safety, poor financial reimbursement for healthcare providers, and vaccine misinformation are often responsible for low immunization rates. This review summarizes the impact of vaccine-preventable illness in those with CLD, updated vaccine guidelines, seroconversion rates in the vaccinated, and barriers faced by healthcare professionals in immunizing those with liver disease.

European Working Group on Sarcopenia in Older People (EWGSOP2) Criteria With Population-Based Skeletal Muscle Index Best Predicts Mortality in Asians With Cirrhosis. J Clin Exp Hepatol 2022; 12:52-60. [PMID: 35068785 PMCID: PMC8766536 DOI: 10.1016/j.jceh.2021.03.015] [Citation(s) in RCA: 11] [Impact Index Per Article: 5.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 11/05/2020] [Accepted: 03/31/2021] [Indexed: 01/03/2023] Open
Abstract
BACKGROUND/AIMS Multiple definitions of sarcopenia exist and the acceptable criterion that best predicts outcome is lacking. We estimated the prevalence of sarcopenia based on four criteria and assessed their utility in predicting mortality in cirrhotics. METHODS In a prospective observational study, consecutive Asian patients with cirrhosis underwent testing for handgrip strength (HGS) and estimation of skeletal muscle index (SMI) using computed tomography at the third lumbar vertebra. Sarcopenia was defined based on the Western cut-off (WC; SMI < 50 cm2/m2 for men and <39 cm2/m2 for women), Asian cut-off (AC; SMI < 36.5 cm2/m2 for men and 30.2 cm2/m2 for women), European Working Group on Sarcopenia in Older People-2nd meeting (EWGSOP2) definition incorporating low HGS (<27 kg for men and <16 kg for women) with low SMI (defined by the WC), and EWGSOP2 definition with low HGS and low SMI (defined by AC). Risk factors for mortality were assessed using multivariate Cox-proportional hazards. RESULTS We included 219 patients with cirrhosis (168 men; mean age 42.6 years) with 50.2% patients having decompensation. Alcohol was the commonest aetiology (33.3%). The prevalence of sarcopenia was highest with the WC (men: 82.1%; women: 62.7%). There was a weak concordance among all criteria (Fleiss' kappa 0.23, 95% confidence interval [CI] 0.10-0.37). Overall, 12-month survival was 86.1% (81.1-91.3%) over a median (interquartile range) follow-up of 12 (6-15) months. Ascites (hazards ratio [HR] 6.27 [95% CI 1.6-24.1]; P < 0.007) and SMI (HR 0.92 [0.85-0.98]; P = 0.021) were independent predictors of mortality. The 12-month mortality rate was higher in patients with sarcopenia, irrespective of criteria (log rank P < 0.05). Low HGS and low SMI (defined by AC) was the best for predicting mortality (HR 3.04 [1.43-6.43]; P = 0.004). CONCLUSION A weak concordance exists amongst various diagnostic definitions of sarcopenia. Sarcopenia diagnosed by a combination of low HGS and population-specific SMI cut-off (AC) best predicts mortality.

The influence of equitable access policies and socioeconomic factors on post-liver transplant survival. EClinicalMedicine 2021; 41:101137. [PMID: 34585128 PMCID: PMC8452797 DOI: 10.1016/j.eclinm.2021.101137] [Citation(s) in RCA: 7] [Impact Index Per Article: 2.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 04/30/2021] [Revised: 08/27/2021] [Accepted: 09/03/2021] [Indexed: 11/13/2022] Open
Abstract
BACKGROUND Survival following liver transplant (LT) is influenced by a variety of factors, including donor risk factors and recipient disease burden and co-morbidities. It is difficult to separate these effects from those of socioeconomic factors, such as income or insurance. The United Network for Organ Sharing (UNOS) created equitable access policies, such as Share 35, to ensure that organs are distributed to individuals with greatest medical need; however, the effect of Share 35 on disparities in post-LT survival is not clear. This study aimed to (1) characterize associations between post-transplant survival and race and ethnicity, income, insurance, and citizenship status, when adjusted for other clinical and demographic factors that may influence survival, and (2) determine if the direction of associations changed after Share 35. METHODS A retrospective, cohort study of adult LT recipients (n = 83,254) from the UNOS database from 2005 to 2019 was conducted. Kaplan-Meier survival graphs and stepwise multivariate cox-regression analyses were performed to characterize the effects of socioeconomic status on post-LT survival, adjusted for recipient and donor characteristics, across the time period and after Share 35. FINDINGS Male sex (HR: 0.93 (95% CI: 0.90-0.96)), private insurance (0.91 (0.88-0.94)), income (0.82 (0.79-0.85)), U.S. citizenship, and Asian (0.81 (0.75-0.88)) or Hispanic (0.82 (0.79-0.86)) race and ethnicity were associated with higher post-transplant survival, after adjustment for clinical and demographic factors (Table 3). These associations were found across the entire time period studied and many persisted after the implementation of Share 35 in 2013 (Table 3; male sex (0.84 (0.79-0.90)), private insurance (0.94 (0.89-1.00)), income (0.82 (0.77-0.89)), and Asian (0.87 (0.73-1.02)) or Hispanic (0.88 (0.81-0.96)) race and ethnicity). INTERPRETATION Recipients' socioeconomic factors at time of transplant may impact long-term post-transplant survival, and a single policy may not significantly alter these structural health inequalities. FUNDING None.

Abstract
Coronavirus disease 2019 (COVID-19), an infection caused by severe acute respiratory syndrome coronavirus-type 2 (SARS-CoV-2), has emerged as a serious threat to public health. Liver transplant (LT) recipients may be at increased risk of acquisition of SARS-CoV-2 infection and higher morbidity and mortality due to constant contact with health-care services, the use of immunosuppressants and frequent comorbidities. In the first part of this review we discuss (1) the epidemiology and risk factors for SARS-CoV-2 infection in LT recipients; (2) the clinical and laboratory features of COVID-19 in this specific population, highlighting differences in presenting signs and symptoms with respect to general populations and (3) the natural history and prognostic factors in LT recipients hospitalized with COVID-19, with particular focus on the possible role of immunosuppression. Thereafter, we review the potential therapeutic options for COVID-19 treatment and prevention. Specifically, we give an overview of current practice in immunosuppressant regimen changes, showing the potential benefits of this strategy, and explore safety and efficacy issues of currently approved drugs in LT recipients. The last topic is dedicated to the potential benefits and pitfalls of vaccination.

Graft injury and re-transplantation in liver transplant patients with COVID-19. JOURNAL OF LIVER TRANSPLANTATION 2021; 1:100008. [PMID: 38620664 PMCID: PMC8062408 DOI: 10.1016/j.liver.2021.100008] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 03/17/2021] [Revised: 04/14/2021] [Accepted: 04/17/2021] [Indexed: 11/24/2022] Open
Abstract
This article discusses the current scene of liver transplantation (LT) in light of the impact of COVID-19, with particular emphasis on the possibility of graft injury and re-transplantation in LT patients infected with SARS-CoV-2. A major concern is whether such patients experience a more severe form of disease which may lead to a higher risk of acute, irreversible liver injury. If this is serious, it may necessitate re-transplantation. This article aims to raise awareness in this relatively under-researched domain. More studies are required to evaluate this issue since it has strong implications in healthcare resource allocation and clinical decision-making. Several potential research directions are proposed, including the possibility of prolonging bridging therapy for non-urgent LT cases: patients with hepatocellular carcinoma; and whether hepatoprotective agents play a role in liver-sparing during SARS-CoV-2 infection. There is also substantial discussion of the relevance of lung injury in LT patients with COVID-19 since it is not uncommon regarding the high expression of ACE2 receptors in the lungs, and that lung injury remains the major cause of death in patients with chronic liver disease.

Obeticholic acid is associated with improvements in AST-to-platelet ratio index and GLOBE score in patients with primary biliary cholangitis. JHEP Rep 2020; 3:100191. [PMID: 33319187 PMCID: PMC7724188 DOI: 10.1016/j.jhepr.2020.100191] [Citation(s) in RCA: 5] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 03/25/2020] [Revised: 08/12/2020] [Accepted: 09/05/2020] [Indexed: 02/07/2023] Open
Abstract
Background & Aims Biochemical markers, including GLOBE score and aspartate aminotransferase-to-platelet ratio index (APRI), are used to stratify risk in patients with primary biliary cholangitis (PBC). This study aimed to evaluate the effects of obeticholic acid (OCA) on categorical shifts in GLOBE score, APRI, and both combined, based on data from POISE, a phase III placebo-controlled trial in patients with PBC who had an incomplete response or were intolerant to ursodeoxycholic acid. Methods In a post hoc analysis, baseline and Month 12 data from POISE were used to calculate the APRI and GLOBE score. Patients were stratified into 3 risk groups based on a combination of APRI (0.54) and GLOBE (0.3 or age-specific) thresholds. Results The analysis included 215 patients (47 low risk; 79 moderate risk; 89 high risk). Using the combined GLOBE score (threshold of 0.3) and APRI thresholds, there was improvement in ≥1 risk stage in 37% and 35% of patients in the OCA 5–10 mg and 10 mg groups, respectively, vs. 12% in the placebo group (both p <0.05). Progression occurred in 10% and 0% in the 5–10 mg and 10 mg groups vs. 37% in the placebo group. Results with GLOBE age-specific thresholds were similar. Conclusions Based on change in APRI and GLOBE score at 12 months, OCA treatment is associated with reduction in the predicted risk of liver-related complications in patients with PBC. Lay summary Primary biliary cholangitis (PBC) is a chronic disease affecting the liver. People who suffer from PBC are at risk of serious long-term complications. Information from certain blood tests can be used to estimate the likelihood of experiencing long-term complications. The results of this study showed that based on blood test results, people taking obeticholic acid, with or without ursodeoxycholic acid, for PBC were predicted to have a better outcome than those taking placebo. Clinical trials registration NCT01473524. Biochemical markers can help estimate risk of progression in patients with primary biliary cholangitis. Data from the POISE trial were used to calculate GLOBE score and aminotransferase-to-platelet ratio index. Obeticholic acid treatment was associated with a shift to lower risk of progression.

Abstract
Non-alcoholic fatty liver disease (NAFLD), specifically its progressive form non-alcoholic steatohepatitis (NASH), represents the fastest growing indication for liver transplantation in Western countries. Diabetes mellitus, morbid obesity and cardiovascular disease are frequently present in patients with NAFLD who are candidates for liver transplantation. These factors require specific evaluation, including a detailed pre-surgical risk stratification, in order to improve outcomes after liver transplantation. Moreover, in the post-transplantation setting, the incidence of cardiovascular events and metabolic complications can be amplified by immunosuppressive therapy, which is a well-known driver of metabolic alterations. Indeed, patients with NASH are more prone to developing early post-transplant complications and, in the long-term, de novo malignancy and cardiovascular events, corresponding to higher mortality rates. Therefore, a tailored multidisciplinary approach is required for these patients, both before and after liver transplantation. Appropriate candidate selection, lifestyle modifications and specific assessment in the pre-transplant setting, as well as pharmacological strategies, adjustment of immunosuppression and a healthy lifestyle in the post-transplant setting, play a key role in correct management.

Impact of COVID-19 on the care of patients with liver disease: EASL-ESCMID position paper after 6 months of the pandemic. JHEP Rep 2020; 2:100169.

Abstract
During the early stages of the coronavirus disease 2019 (COVID-19) pandemic, EASL and ESCMID published a position paper to provide guidance for physicians involved in the care of patients with chronic liver disease. While some healthcare systems are returning to a more normal routine, many countries and healthcare systems have been, or still are, overwhelmed by the pandemic, which is significantly impacting on the care of these patients. In addition, many studies have been published focusing on how COVID-19 may affect the liver and how pre-existing liver diseases might influence the clinical course of COVID-19. While many aspects remain poorly understood, it has become increasingly evident that pre-existing liver diseases and liver injury during the disease course must be kept in mind when caring for patients with COVID-19. This review should serve as an update on the previous position paper, summarising the evidence for liver disease involvement during COVID-19 and providing recommendations on how to return to routine care wherever possible.

Effect of Donor Hepatic Steatosis on Ischemia Reperfusion Injury in Liver Transplant Recipient. J Clin Exp Hepatol 2020; 10:236-244. [PMID: 32405180 PMCID: PMC7212288 DOI: 10.1016/j.jceh.2019.07.004] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/02/2019] [Accepted: 07/05/2019] [Indexed: 01/02/2023] Open
Abstract
INTRODUCTION Ischemia reperfusion injury (IRI) is an important complication of liver transplant (LT). The donor risk index, which does not incorporate steatosis, includes several variables known to impact on allograft survival. The purpose of this study was to report on donor liver allograft steatosis and its association with severity of IRI. AIM The aim of this study was to determine the effect of type and grade of donor liver steatosis on the occurrence and severity of IRI in LT recipients. METHODS This was an observational study conducted at a single center over a period of 37 months from July 2013 to August 2016. Liver biopsy was performed twice, initially at the time of procurement before graft perfusion for steatosis assessment. Steatosis was classified as microsteatosis (MiS) or macrosteatosis (MaS) with mild, moderate, or severe grade. Second biopsy for IRI assessment was taken before skin closure in death donor LT (DDLT) and at the time of transaminitis in postoperative period (<72 hrs) in living donor LT (LDLT). IRI was graded as per neutrophil infiltrate, apoptosis, and hepatocyte cell dropout. Prevalence of IRI and association steatosis was studied along with other factors. RESULTS Among 53 subjects, 35 were DDLTs and 18 were LDLTs. All live donor grafts were restricted to <15% MaS and the deceased liver grafts had different type and degree of steatosis. In DDLTs, the association between occurrence of IRI and MaS was not statistically significant (P = 0.201). In DDLTs, the mild steatosis was not significantly associated with IRI. Death donor and ischemic time were significantly associated with IRI. Child's stage and MELD scores, gender, and age were not associated with risk of IRI. Severity of IRI is significantly associated with 3-month mortality (P = 0.001). CONCLUSION In patients with mild steatosis, IRI does not correlate with steatosis. However, more patients with moderate and severe steatosis are needed to define the relationship of the two in this group of patients.

Functional Status at Liver Transplant Waitlisting Correlates With Greater Odds of Encephalopathy, Ascites, and Spontaneous Bacterial Peritonitis. J Clin Exp Hepatol 2020; 10:413-420. [PMID: 33029049 PMCID: PMC7527846 DOI: 10.1016/j.jceh.2020.04.015] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 02/21/2020] [Accepted: 04/19/2020] [Indexed: 12/12/2022] Open
Abstract
BACKGROUND & AIMS Whether higher liver transplant (LT) waitlist mortality in patients with poor functional status (FS) is mediated by higher prevalence of cirrhosis complications is not clear. We aim to evaluate the impact of FS on risk of hepatic encephalopathy (HE), ascites, and spontaneous bacterial peritonitis (SBP) among adults listed for LT. METHODS Using 2005-2018 United Network for Organ Sharing LT data, we retrospectively evaluated the impact of FS on prevalence of ascites, HE, and SBP among adults listed for LT using Karnofsky Performance Status Score categories (KPSS-1: FS 80-100%, KPSS-2: 60-70%, KPSS-3: 40-50%, KPSS-4: 10-30%), stratified by underlying liver disease etiology. Between-group comparisons used chi-squared methods and adjusted multivariate logistic regression. RESULTS Among 100,618 adults listed for LT (68.8% male, 72.4% non-Hispanic white) 35.2% were KPSS-1, 36.6% KPSS-2, 15.7% KPSS-3, and 12.6% KPSS-4 at time of LT waitlist registration. Patients with worse FS were significantly more likely to have ascites, HE, and SBP at time of waitlist registration (KPSS-1 vs. KPSS-4: ascites, 66% vs. 93%; HE, 81% vs. 49%; SBP, 4% vs. 16%, p < 0.001 for all). On multivariate regression, compared with patients with KPSS-1, those with KPSS-4 had significantly higher odds of ascites (odds ratio [OR]: 1.49, 95% confidence interval [CI]: 1.37-1.62, p < 0.01), HE (OR: 1.69, 95% CI: 1.59-1.80, p < 0.01), and SBP (OR: 2.17, 95% CI: 1.98-2.38, p < 0.01), which was observed across all liver disease etiologies. CONCLUSION Worse FS is associated with higher odds of cirrhosis complications including ascites, HE, and SBP, which was observed across all liver disease etiologies.

Abstract
BACKGROUND/OBJECTIVES Acute liver failure (ALF) is rare and associated with poor outcomes. The outcomes of ALF and predictors of outcome may vary as per the etiology. There are limited data on the predictors of spontaneous survival among patients with ALF of non-A-E hepatitis or cryptogenic etiology. We aimed to assess clinical course, complications, and outcome of non-A-E etiology ALF. METHODS In this prospective analysis, all consecutive ALF patients (n = 1555; January 1986-June 2018) were analyzed. Non-A-E-ALF was defined as ALF that could not be attributed to known etiologies such as drugs, viral hepatitis, autoimmune hepatitis, and Wilson's disease. Clinical course, complications, and outcomes of non-A-E-ALF patients who did not undergo liver transplantation were analyzed. Unadjusted and adjusted odds ratios (ORs) were calculated. RESULTS Non-A-E-ALF constituted 34.6% (n = 538) of all ALF patients, whereas hepatitis E virus (HEV), hepatitis B virus (HBV), and anti-tuberculosis therapy (ATT) accounted for 29.5% (n = 459), 8.6% (n = 134), and 7.4% (n = 115), respectively. Among non-A-E-ALF patients, mean age was 28.8 ± 12.0 years, 50.9% females, majority (63.1%) had hyperacute presentation, and 79.2% had advanced encephalopathy at presentation. The frequency of cerebral edema in non-A-E-ALF (53.3%) was higher than that in HEV-ALF (41.2%) and ATT-ALF (44.2%), P < 0.001. The survival rate in non-A-E-ALF (37.5%) was poorer than HEV-ALF (54.9%) and was comparable to that in HBV (35.8%) and ATT (29.6%) induced ALF. The baseline prothrombin time prolongation (odds ratio [OR] 1.041; 95% confidence intervals [CI], 1.017-1.065) and infection (OR 2.366; 95%CI, 1.107-5.055) were independent predictors of outcome in non-A-E-ALF. The 3-days acute liver failure early dynamic model had the best value in predicting the outcome. CONCLUSIONS Non-A-E-ALF accounts for one-third of all cases of ALF and is associated with poor spontaneous survival.

Abstract
Progressive familial intrahepatic cholestasis (PFIC) is a group of rare disorders which are caused by defect in bile secretion and present with intrahepatic cholestasis, usually in infancy and childhood. These are autosomal recessive in inheritance. The estimated incidence is about 1 per 50,000 to 1 per 100,000 births, although exact prevalence is not known. These diseases affect both the genders equally and have been reported from all geographical areas. Based on clinical presentation, laboratory findings, liver histology and genetic defect, these are broadly divided into three types-PFIC type 1, PFIC type 2 and PFIC type 3. The defect is in ATP8B1 gene encoding the FIC1 protein, ABCB 11 gene encoding BSEP protein and ABCB4 gene encoding MDR3 protein in PFIC1, 2 and 3 respectively. The basic defect is impaired bile salt secretion in PFIC1/2 whereas in PFIC3, it is reduced biliary phospholipid secretion. The main clinical presentation is in the form of cholestatic jaundice and pruritus. Serum gamma glutamyl transpeptidase (GGT) is normal in patients with PFIC1/2 while it is raised in patients with PFIC3. Treatment includes nutritional support (adequate calories, supplementation of fat soluble vitamins and medium chain triglycerides) and use of medications to relieve pruritus as initial therapy followed by biliary diversion procedures in selected patients. Ultimately liver transplantation is needed in most patients as they develop progressive liver fibrosis, cirrhosis and end stage liver disease. Due to the high risk of developing liver tumors in PFIC2 patients, monitoring is recommended from infancy. Mutation targeted pharmacotherapy, gene therapy and hepatocyte transplantation are being explored as future therapeutic options.

Abstract
Liver transplant (LT) is a major surgical undertaking involving major fluid shifts, hemodynamic instability and metabolic derangements in a patient with preexisting liver failure and multisystemic derangements. Monitoring and organ support initiated in the preoperative phase is continued intraoperatively and into the postoperative phase to ensure an optimal outcome. As cardiovascular events are the leading cause of non-graft related death among LT recipients, major emphasis is placed on cardiovascular monitoring. The other essential monitoring are the continuous assessment of coagulapathy, extent of metabolic derangements, dyselectrolytemis and intracranial pressure monitoring in patients with fulminant hepatic failure. The type and extent of monitoring differs with need according to preexisting child status of the patient and the extent of systemic derangements. It also varies among transplant centers and is mainly determined by individual or institutional practices.

Abstract
BACKGROUND Deceased donor (DDLT) and living donor (LDLT) liver transplant (LT) is in vogue in several centers in India. Most centers are resorting to LDLT as a preferred surgery due to shortage of deceased donor liver. The risk of infection and its effect on survival in both groups of recipients from the Indian subcontinent are not known. The study was conducted to compare the bacterial infection rates among LDLT and DDLT recipients and their impact on survival at a tertiary referral center. METHODS Retrospective data on 67 LT recipients were reviewed. Data on pre-, per-, and postoperative bacterial infection rates and the common isolates were obtained. RESULTS Thirty-five patients had LDLT and 32 had DDLT. The prevalence of pre-operative bacterial infection and the isolates was similar in both groups. The perioperative bacterial infection rates were significantly higher in DDLT recipients (P < 0.01) (relative risk: 1.44 95% confidence interval 1.04-1.9). In both LDLT and DDLT, the common source was urinary tract followed by bloodstream infection. The common bacterial isolates in either transplant were Klebsiella followed by Escherichia coli, Pseudomonas spp. and nonfermenting gram-negative bacteria. Six patients (four LDLT; two DDLT) were treated for tuberculosis. Among the risk factors, cold ischemic time, and duration of stay in the intensive care unit was significantly higher for DDLT (p < 0.01). The death rates were not significantly different in the two groups. However, the odds for death were significantly high at 26.8 (p < 0.05) for postoperative bacterial infection and 1.8 (p < 0.001) for past alcohol. CONCLUSION Liver transplant recipients are at high-risk for bacterial infection irrespective of type of transplant, more so in DDLT.
