Recanalized Paraumbilical Vein Leading to Hepatic Myelopathy Causing Spastic Paraparesis in a Patient with Chronic Liver Disease.

A 34-year-old male visited our hospital with complaints of recurrent episodes of altered behavior since past 6 months along with difficulty in walking since past 3 months. He was diagnosed of chronic liver disease in the past. Examination revealed spasticity and brisk deep tendon reflexes in both the lower limbs. His blood investigations and spinal cord imaging was normal. Based on his clinical features, a possibility of portosystemic shunting leading to portosystemic encephalopathy (PSE) and shunt myelopathy was suspected. A computed tomography portography showed a recanalized paraumblical vein draining portal blood into external iliac veins. Patient underwent shunt occlusion (Figure- 2). One month after the procedure, while there was no recurrence of symptoms of PSE, those of myelopathy remained unchanged. Shunt myelopathy is a rare complication of spontaneous or iatrogenic portosystemic shunts. Unlike PSE, the management of shunt myelopathy is uncertain due to limited evidence. Limited evidence suggests reversal of myelopathy after early shunt occlusion, highlighting the irreversible changes that may set in spinal cord due to delayed diagnosis. Our case highlights an important but a rare complication of portosystemic shunting in chronic liver disease which should be kept in mind if these patients develop symptoms attributable to spinal cord disease.

Improving Transplant-free Survival With Low-volume Plasma Exchange to Treat Children With Rodenticide Induced Hepatotoxicity.

Background: In a prior report, no patient with rodenticidal hepatotoxicity who met Kochi criteria (MELD score ≥36 or baseline INR ≥6 with hepatic encephalopathy) (PMID: 26310868) for urgent liver transplantation survived with medical management alone. Plasma exchange (PLEX) may improve survival in these patients. Objectives: We describe our experience with low-volume PLEX (PLEX-LV) in treating rodenticide ingestion induced hepatotoxicity in children. Methods: From prospectively collected database of rodenticidal hepatotoxicity patients managed as in-patient with department of Hepatology from December 2017 to August 2021, we retrospectively studied outcomes in children (≤18 years). Hepatotoxicity was categorized as acute liver injury (ALI, coagulopathy alone) or acute liver failure (ALF, coagulopathy and encephalopathy). Kochi criteria was used to assess need for urgent liver transplantation. The primary study outcome was one-month survival. Results: Of the 110 rodenticidal hepatotoxicity patients, 32 children (females: 56%; age: 16 [4.7-18] years; median, range) constituted the study patients. The study patients presented 4 (1-8) days after poison consumption (impulsive suicidal intent:31, accidental:1). Twenty children (62%) had ALI [MELD: 18 (8-36)] and 12 (38%) had ALF [MELD: 37 (24-45)].All children received standard medical care, including N-acetyl cysteine; ALF patients also received anti-cerebral edema measures. None of the patient families opted for liver transplantation. Seventeen children (ALI: 6, ALF: 11) were treated with PLEX-LV (3 [1-5] sessions, volume of plasma exchanged per session: 26 [13-38] ml/kg body weight) and peri-procedure low dose prednisolone.At 1 month, 28 of the 32 children (87.5%) were alive (4 ALF patients died). Of 10 children who met Kochi listing criteria for urgent liver transplantation, two children were ineligible for PLEX-LV (due to hemodynamic instability) and of the remaining 8 children treated by PLEX-LV, 6 (75%) survived. Conclusions: PLEX-LV shows promise as an effective non-liver transplant treatment in children with rodenticidal hepatotoxicity.

Palliative Care for Patients with End-Stage Liver Disease.

End-stage liver disease (ESLD) is the culmination of progression of chronic liver disease to cirrhosis, decompensation, and chronic liver failure, featuring portal hypertension or hepatocellular failure-related complications. Liver transplantation offers improved long-term survival for these patients but is negatively influenced by donor availability, financial constraints in developing countries, active substance abuse, progression of disease or malignancy on wait-list, sepsis and extrahepatic organ involvement. In this context, palliative care (PC), an interdisciplinary medical practice that aim to prevent and relieve suffering, offers best possible quality of life and is not limited to end-of-life care. It also encompasses achievable goals such as symptom control and aggressive disease-modifying treatments or interventions that beneficially alter the natural course of the disease to offer curative intend. In this narrative review, we discuss the prognostic factors that define disease course in ESLD, various indications and challenges in PC for advanced cirrhosis and management options for major symptom burden in patients with ESLD based on evidence-based best practice.

Emerging Biomarkers in Alcohol-associated Hepatitis.

Alcohol-associated hepatitis (AH) is a clinical syndrome of jaundice, abdominal pain, and anorexia due to prolonged heavy alcohol intake. AH is associated with changes in gene expression, cytokines, immune response, and the gut microbiome. There are limited biomarkers to diagnose and prognosticate in AH, but several non-invasive biomarkers are emerging. In this review, clinical risk-stratifying algorithms, promising AH biomarkers like cytokeratin-18 fragments, genetic polymorphisms, and microRNAs will be reviewed.

The positive impact of the COVID 19 pandemic on organ utilisation in liver transplantation.

Background: As the world recovers from the aftermath of devastating waves of an outbreak, the ongoing Coronavirus disease 2019 pandemic has presented a unique perspective to the transplantation community of ''organ utilisation'' in liver transplantation, a poorly defined term and ongoing hurdle in this field. To this end, we report the key metrics of transplantation activity from a high-volume liver transplantation centre in the United Kingdom over the past two years. Methods: Between March 2019 and February 2021, details of donor liver offers received by our centre from National Health Service Blood & Transplant, and of transplantation were reviewed. Differences in the activity before and after the outbreak of the pandemic, including short term post-transplant survival, have been reported. Results: The pandemic year at our centre witnessed a higher utilisation of Donation after Cardiac Death livers (80.4% vs. 58.3%, p = 0.016) with preserved United Kingdom donor liver indices and median donor age (2.12 vs. 2.02, p = 0.638; 55 vs. 57 years, p = 0.541) when compared to the pre-pandemic year. The 1- year patient survival rates for recipients in both the periods were comparable. The pandemic year, that was associated with increased utilisation of Donation after Cardiac Death livers, had an ischaemic cholangiopathy rate of 6%. Conclusions: The pressures imposed by the pandemic led to increased utilisation of specific donor livers to meet patient needs and minimise the risk of death on the waiting list, with apparently preserved early post-transplant survival. Optimum organ utilisation is a balancing act between risk and benefit for the potential recipient, and technologies like machine perfusion may allow surgeons to increase utilisation without compromising patient outcomes.

Implications of anaemia and response to anaemia treatment on outcomes in patients with cirrhosis.

Background & Aims: Anaemia is frequently observed in patients with cirrhosis and was identified as a predictor of adverse outcomes, such as increased mortality and occurrence of acute-on-chronic liver failure. To date, the possible effects of iron supplementation on these adverse outcomes are not well described. We therefore aimed to assess the role of iron supplementation in patients with cirrhosis and its capability to improve prognosis. Methods: Laboratory diagnostics were performed in consecutive outpatients with cirrhosis admitted between July 2018 and December 2019 to the University Hospital Essen. Associations with transplant-free survival were assessed in regression models. Results: A total of 317 outpatients with cirrhosis were included, of whom 61 received a liver transplant (n = 19) or died (n = 42). In multivariate Cox regression analysis, male sex (hazard ratio [HR] = 3.33, 95% CI [1.59, 6.99], p = 0.001), model for end-stage liver disease score (HR = 1.19, 95% CI [1.11, 1.27], p <0.001) and the increase of haemoglobin levels within 6 months (ΔHb6) (HR = 0.72, 95% CI [0.63, 0.83], p <0.001) were associated with transplant-free survival. Regarding the prediction of haemoglobin increase, intake of rifaximin (beta = 0.50, SD beta = 0.19, p = 0.007) and iron supplementation (beta = 0.79, SD beta = 0.26, p = 0.003) were significant predictors in multivariate analysis. Conclusions: An increase of haemoglobin levels is associated with improvement of transplant-free survival in patients with cirrhosis. Because the prediction of haemoglobin increase significantly depends on rifaximin and iron supplementation, application of these two medications can have an important impact on the outcome of these patients. Impact and implications: Anaemia is very common in patients with cirrhosis and is known to be a predictor of negative outcomes, but little is known about the effect of iron substitution in these individuals. In our cohort, increase of haemoglobin levels improved transplant-free survival of patients with cirrhosis. The increase of haemoglobin levels was mainly induced by iron supplementation and was even stronger in the case of concomitant use of iron and rifaximin. Clinical trial registration: UME-ID-10042.

Psoas Muscle Index: A Simple and Reliable Method of Sarcopenia Assessment on Computed Tomography Scan in Chronic Liver Disease and its Impact on Mortality.

Objectives: Psoas muscle parameters have been proposed as a simple and quick method for sarcopenia assessment. The aim of this study was to assess sarcopenia in cirrhotics by psoas muscle on computed tomography and its impact on mortality. Methods: One hundred and fifty patients (75 cirrhotics, 75 subjects) were assessed for psoas muscle on CT scan. Psoas muscle index (PMI) was calculated as 'total psoas muscle area/(height of subject)2'. Cut off values for sarcopenia diagnosis were derived from local subjects (n = 75) who did not have cirrhosis/other causes of sarcopenia. Results: Sarcopenia assessed by PMI was seen in 36% (n = 27) of the cirrhotics. Sarcopenia was significantly higher in patients having Child-Pugh C. Ascites, hepatic encephalopathy (HE) and gastro-intestinal bleed were seen in 48%, 18.7% and 24%, respectively. Sarcopenia was significantly associated with ascites and HE (P < 0.05). Out of the 75 cases, 53 cases completed the follow-up period of 1 year. Among the 20 cases who had sarcopenia, 35% (n = 7) succumbed to liver-related illness during 1 year follow-up, and out of the 33 cases without sarcopenia, only 6% (n = 2) died. The association of sarcopenia and 1 year mortality was statistically significant (P = 0.01). Conclusions: The PMI, a simple method for sarcopenia assessment detected sarcopenia in 36% of cirrhotics. Patients with sarcopenia had a significantly higher 1 year mortality rate and appropriate prognostication of such patients is needed.

Recompensation in Cirrhosis: Current Evidence and Future Directions.

The natural history of cirrhosis has usually been conceptualized in the context of progression from compensated cirrhosis to subsequent stages of decompensation. While this unidirectional concept is the most common pathophysiological trajectory, there has been an emerging understanding of a subgroup of patients which undergo recompensation. While literature mostly based on transplant waitlist registries have indicated towards such a population who experience disease regression, the overall literature about this entity remains inexplicit. An effort to generate consensus on defining recompensation has been attempted which comes with its own nuances and limitations. We summarize the available literature on this emerging yet controversial concept of recompensation in cirrhosis and delve into future implications and impact on real-life practice.

Elevated serum levels of glial fibrillary acidic protein are associated with covert hepatic encephalopathy in patients with cirrhosis.

Background & Aims: Blood biomarkers facilitating the diagnosis of covert hepatic encephalopathy (CHE) in patients with cirrhosis are lacking. Astrocyte swelling is a major component of hepatic encephalopathy. Thus, we hypothesised that glial fibrillary acidic protein (GFAP), the major intermediate filament of astrocytes, might facilitate early diagnosis and management. This study aimed to investigate the utility of serum GFAP (sGFAP) levels as a biomarker of CHE. Methods: In this bicentric study, 135 patients with cirrhosis, 21 patients with ongoing harmful alcohol use and cirrhosis, and 15 healthy controls were recruited. CHE was diagnosed using psychometric hepatic encephalopathy score. sGFAP levels were measured using a highly sensitive single-molecule array (SiMoA) immunoassay. Results: In total, 50 (37%) people presented with CHE at study inclusion. Participants with CHE displayed significantly higher sGFAP levels than those without CHE (median sGFAP, 163 pg/ml [IQR 136; 268] vs. 106 pg/ml [IQR 75; 153]; p <0.001) or healthy controls (p <0.001). sGFAP correlated with results in psychometric hepatic encephalopathy score (Spearman's ρ = -0.326, p <0.001), model for end-stage liver disease score (Spearman's ρ = 0.253, p = 0.003), ammonia (Spearman's ρ = 0.453, p = 0.002), and IL-6 serum levels (Spearman's ρ = 0.323, p = 0.006). Additionally, sGFAP levels were independently associated with the presence of CHE in multivariable logistic regression analysis (odds ratio 1.009; 95% CI 1.004-1.015; p <0.001). sGFAP levels did not differ between patients with alcohol-related cirrhosis vs. patients with non-alcohol-related cirrhosis or between patients with ongoing alcohol use vs. patients with discontinued alcohol use.Conclusions: sGFAP levels are associated with CHE in patients with cirrhosis. These results suggest that astrocyte injury may already occur in patients with cirrhosis and subclinical cognitive deficits and that sGFAP could be explored as a novel biomarker. Impact and implications: Blood biomarkers facilitating the diagnosis of covert hepatic encephalopathy (CHE) in patients with cirrhosis are lacking. In this study, we were able to demonstrate that sGFAP levels are associated with CHE in patients with cirrhosis. These results suggest that astrocyte injury may already occur in patients with cirrhosis and subclinical cognitive deficits and that sGFAP could be explored as a novel biomarker.

Infection prevention and control programme and COVID-19 measures: Effects on hospital-acquired infections in patients with cirrhosis.

Background & Aims: Bacterial infections affect survival of patients with cirrhosis. Hospital-acquired bacterial infections present a growing healthcare problem because of the increasing prevalence of multidrug-resistant organisms. This study aimed to investigate the impact of an infection prevention and control programme and coronavirus disease 2019 (COVID-19) measures on the incidence of hospital-acquired infections and a set of secondary outcomes, including the prevalence of multidrug-resistant organisms, empiric antibiotic treatment failure, and development of septic states in patients with cirrhosis. Methods: The infection prevention and control programme was a complex strategy based on antimicrobial stewardship and the reduction of patient's exposure to risk factors. The COVID-19 measures presented further behavioural and hygiene restrictions imposed by the Hospital and Health Italian Sanitary System recommendations. We performed a combined retrospective and prospective study in which we compared the impact of extra measures against the hospital standard. Results: We analysed data from 941 patients. The infection prevention and control programme was associated with a reduction in the incidence of hospital-acquired infections (17 vs. 8.9%, p <0.01). No further reduction was present after the COVID-19 measures had been imposed. The impact of the infection prevention and control programme remained significant even after controlling for the effects of confounding variables (odds ratio 0.44, 95% CI 0.26-0.73, p = 0.002). Furthermore, the adoption of the programme reduced the prevalence of multidrug-resistant organisms and decreased rates of empiric antibiotic treatment failure and the development of septic states. Conclusions: The infection prevention and control programme decreased the incidence of hospital-acquired infections by nearly 50%. Furthermore, the programme also reduced the prevalence of most of the secondary outcomes. Based on the results of this study, we encourage other liver centres to adopt infection prevention and control programmes. Impact and implications: Infections are a life-threatening problem for patients with liver cirrhosis. Moreover, hospital-acquired infections are even more alarming owing to the high prevalence of multidrug-resistant bacteria. This study analysed a large cohort of hospitalised patients with cirrhosis from three different periods. Unlike in the first period, an infection prevention programme was applied in the second period, reducing the number of hospital-acquired infections and containing multidrug-resistant bacteria. In the third period, we imposed even more stringent measures to minimise the impact of the COVID-19 outbreak. However, these measures did not result in a further reduction in hospital-acquired infections.

National Liver Allocation Policy-Consensus Document by the Liver Transplantation Society of India for a Nationally Uniform System of Allocation of Deceased Donor Liver Grafts.

Background: Deceased donor liver transplantation (DDLT) is increasing in India and now constitutes nearly one-third of all liver transplantation procedures performed in the country. There is currently no uniform national system of allocation of deceased donor livers. Methods: A national task force consisting of 19 clinicians involved in liver transplantation from across the country was constituted under the aegis of the Liver Transplantation Society of India to develop a consensus document addressing the above issues using a modified Delphi process of consensus development. Results: The National Liver Allocation Policy consensus document includes 46 statements covering all aspects of DDLT, including minimum listing criteria, listing for acute liver failure, DDLT wait-list management, system of prioritisation based on clinical urgency for adults and children, guidelines for allocation of paediatric organs and allocation priorities for liver grafts recovered from public sector hospitals. Conclusion: This document is the first step in the setting up of a nationally consistent policy of deceased donor liver allocation.

Acute Kidney Injury (AKI) at Admission Predicts Mortality in Patients With Severe Alcoholic Hepatitis (SAH).

Background & aims: Severe alcoholic hepatitis (SAH) is a grave condition, and the presence of acute kidney injury (AKI) further jeopardizes patient survival. However, the impact of AKI on survival in SAH has not been assessed from this region of Asia. Materials and methods: This study was conducted on consecutive alcohol-associated liver disease (ALD) patients hospitalized in Gastroenterology Department, SCB Medical College, Cuttack, India, between October 2016 and December 2018. On diagnosis of SAH (mDF score ≥32), demographic, clinical, and laboratory parameters were recorded, and survival was compared between patients with and without AKI (AKIN criteria). In addition, survival was compared among SAH patients defined by other criteria and prognostic models in the presence and absence of AKI. Results: 309 (70.71%) of ALD patients had SAH, and 201 (65%) of them had AKI. SAH patients with AKI had higher total leucocyte count, total bilirubin, serum creatinine, serum urea, INR, MELD (UNOS), MELD (Na+), CTP score, mDF score, Glasgow score, ABIC score, and increased prevalence of acute on chronic liver failure (ACLF) as per EASL-CLIF Consortium criteria (P < 0.001). Further, they had prolonged hospital stay, and increased death during hospitalization, at 28 days as well as 90 days (P < 0.001). Significant differences in survival were also seen in SAH (as per MELD, ABIC, and GAHS criteria) patients above the marked cut offs in respect to AKI. Conclusions: Over two-thirds of ALD patients had SAH, and about two-thirds had AKI. Patients with SAH and AKI had an increased prevalence of ACLF, longer hospital stay, and increased mortality during hospitalization at 28 days and 90 days. Lay summary: SAH is a critical condition, and the presence of AKI negatively affects their survival. Hence, early identification of SAH and AKI, as well as early initiation of treatment, is crucial for better survival. Our study from the coastal part of eastern India is the first to demonstrate the prevalence of SAH among patients with ALD along with the prevalence of AKI among SAH patients in this region. This knowledge will be helpful in managing these patients from this region of world.

A Review of Machine Perfusion Strategies in Liver Transplantation.

The acceptance of liver transplantation as the standard of care for end-stage liver diseases has led to a critical shortage of donor allografts. To expand the donor organ pool, many countries have liberalized the donor criteria including extended criteria donors and donation after circulatory death. These marginal livers are at a higher risk of injury when they are preserved using the standard static cold storage (SCS) preservation techniques. In recent years, research has focused on optimizing organ preservation techniques to protect these marginal livers. Machine perfusion (MP) of the expanded donor liver has witnessed considerable advancements in the last decade. Research has showed MP strategies to confer significant advantages over the SCS techniques, such as longer preservation times, viability assessment and the potential to recondition high risk allografts prior to implantation. In this review article, we address the topic of MP in liver allograft preservation, with emphasis on current trends in clinical application. We discuss the relevant clinical trials related to the techniques of hypothermic MP, normothermic MP, hypothermic oxygenated MP, and controlled oxygenated rewarming. We also discuss the potential applications of ex vivo therapeutics which may be relevant in the future to further optimize the allograft prior to transplantation.

A randomized, double-blind, placebo-controlled phase IIa trial of efruxifermin for patients with compensated NASH cirrhosis.

Background & Aims: Efruxifermin has shown clinical efficacy in patients with non-alcoholic steatohepatitis (NASH) and F1-F3 fibrosis. The primary objective of the BALANCED Cohort C was to assess the safety and tolerability of efruxifermin in patients with compensated NASH cirrhosis. Methods: Patients with NASH and stage 4 fibrosis (n = 30) were randomized 2:1 to receive efruxifermin 50 mg (n = 20) or placebo (n = 10) once-weekly for 16 weeks. The primary endpoint was safety and tolerability of efruxifermin. Secondary and exploratory endpoints included evaluation of non-invasive markers of liver injury and fibrosis, glucose and lipid metabolism, and changes in histology in a subset of patients who consented to end-of-study liver biopsy. Results: Efruxifermin was safe and well-tolerated; most adverse events (AEs) were grade 1 (n = 7, 23.3%) or grade 2 (n = 19, 63.3%). The most frequent AEs were gastrointestinal, including transient, mild to moderate diarrhea, and/or nausea. Significant improvements were noted in key markers of liver injury (alanine aminotransferase) and glucose and lipid metabolism. Sixteen-week treatment with efruxifermin was associated with significant reductions in non-invasive markers of fibrosis including Pro-C3 (least squares mean change from baseline [LSMCFB] -9 µg/L efruxifermin vs. -3.4 µg/L placebo; p = 0.0130) and ELF score (-0.4 efruxifermin vs. +0.4 placebo; p = 0.0036), with a trend towards reduced liver stiffness (LSMCFB -5.7 kPa efruxifermin vs. -1.1 kPa placebo; n.s.). Of 12 efruxifermin-treated patients with liver biopsy after 16 weeks, 4 (33%) achieved fibrosis improvement of at least one stage without worsening of NASH, while an additional 3 (25%) achieved resolution of NASH, compared to 0 of 5 placebo-treated patients. Conclusions: Efruxifermin appeared safe and well-tolerated with encouraging improvements in markers of liver injury, fibrosis, and glucose and lipid metabolism following 16 weeks of treatment, warranting confirmation in larger and longer term studies. Lay summary: Cirrhosis resulting from non-alcoholic steatohepatitis (NASH), the progressive form of non-alcoholic fatty liver disease, represents a major unmet medical need. Currently there are no approved drugs for the treatment of NASH. This proof-of-concept randomized, double-blind clinical trial demonstrated the potential therapeutic benefit of efruxifermin treatment compared to placebo in patients with cirrhosis due to NASH. Clinical Trial Number: NCT03976401.

Sarcopenia in the Cirrhotic Patient: Current Knowledge and Future Directions.

Cirrhosis predisposes to abnormalities in energy, hormonal, and immunological homeostasis. Disturbances in these metabolic processes create susceptibility to sarcopenia or pathological muscle wasting. Sarcopenia is prevalent in cirrhosis and its presence portends significant adverse outcomes including the length of hospital stay, infectious complications, and mortality. This highlights the importance of identification of at-risk individuals with early nutritional, therapeutic and physical therapy intervention. This manuscript summarizes literature relevant to sarcopenia in cirrhosis, describes current knowledge, and elucidates possible future directions.

The ALBI score: From liver function in patients with HCC to a general measure of liver function.

The (albumin-bilirubin) 'ALBI' score is an index of 'liver function' that was recently developed to assess prognosis in patients with hepatocellular carcinoma, irrespective of the degree of underlying liver fibrosis. Other measures of liver function, such as model for end-stage liver disease (MELD) and Child-Pugh score, which were introduced for specific clinical scenarios, have seen their use extended to other areas of hepatology. In the case of ALBI, its application has been increasingly extended to chronic liver disease in general and in some instances to non-liver diseases where it has proven remarkably accurate in terms of prognosis. With respect to chronic liver disease, numerous publications have shown that ALBI is highly prognostic in patients with all types and stages of chronic liver disease. Outside of liver disease, ALBI has been reported as being of prognostic value in conditions ranging from chronic heart failure to brain tumours. Whilst in several of these reports, explanations for the relationship of liver function to a clinical condition have been proposed, it has to be acknowledged that the specificity of ALBI for liver function has not been clearly demonstrated. Nonetheless, and similar to the MELD and Child-Pugh scores, the lack of any mechanistic basis for ALBI's clinical utility does not preclude it from being clinically useful in certain situations. Why albumin and bilirubin levels, or a combination thereof, are prognostic in so many different diseases should be studied in the future.

Physical Activity Patterns in Frail and Nonfrail Patients With End-Stage Liver Disease.

Background: Frailty commonly complicates cirrhosis and is associated with poorer outcomes. While patients with cirrhosis may be sedentary, there are few comprehensive descriptions of their physical activity (PA) patterns related to frailty. Our aim was to identify PA characteristics that may be used in interventions to improve PA and reduce frailty. Methods: In a cross-sectional cohort study, forty patients with cirrhosis (mean age 63; 30 nonfrail, 10 frail) wore an accelerometer/thermal sensing armband for 7 days. Postural status (e.g., upright movement, upright sedentary, lying down), Metabolic Equivalent of Tasks (METs) and active bouts were identified. Results: Patients were highly sedentary most of the time (89 ± 7% and 85 ± 10% of the day, in frail and nonfrail cirrhotics, respectively). Compared with nonfrail cirrhotics, frail patients spent significantly shorter amount of time moving in an upright position (7% ± 5 vs. 12% ± 5, P = 0.013 in frail and nonfrail cirrhotics, respectively), had significantly fewer and shorter durations of active bouts per day (number of active bouts: 9 ± 12 vs. 19 ± 14; duration: 13.2 ± 1.5 min and 15.9 ± 2.6 min in frail and nonfrail cirrhotics, respectively), and had a lower amount of steps per wear time hours (41.7 ± 37.1 vs. 116.8 ± 85.4, P = 0.003 in frail and nonfrail, respectively). Traditional measures such as METs or aerobic bouts did not differ between groups. Conclusions: Active bout measures, as opposed to more traditional measures such as METs, differentiate between frail and nonfrail cirrhotics suggesting they may be used to assess changes resulting from targeted interventions to improve physical activity.

Livogrit, a herbal formulation of Boerhavia diffusa, Phyllanthus niruri and Solanum nigrum reverses the thioacetamide induced hepatocellular toxicity in zebrafish model.

Research studies in the past years have shown encouraging therapeutic potential of herbal medicines in liver ailments. Livogrit is a well characterized formulation prepared by mixing extracts of plants, Boerhavia diffusa, Phyllanthus niruri and Solanum nigrum in precise ratios. Our study demonstrates the curative role of Livogrit in thioacetamide (TAA) induced zebrafish model of hepatotoxicity. This is a systematic study, wherein we first screened Livogrit for an effective dose and treatment time-course. Once established, we conducted subsequent experiments to compare the hepatoprotective effects of Livogrit with a reference drug, prednisone. We evaluated a wide range of liver function variables including, albumin, AST, bilirubin, creatinine, platelet clotting factor, INR and sodium blood serum to assess the degree of liver dysfunctionality. Results from screening experiments suggested that Livogrit treatment for 14 days at an effective dose (ED3-142 µg/kg) significantly revamped the deviated serum biochemistry. The experiments comparing prednisone and Livogrit demonstrated that the treatment with the herbal formation was more effective against TAA-induced hepatotoxicity. Liver function parameters indicating hepatic dysfunctionality showed better recovery with Livogrit as compared to prednisone. Furthermore, we enumerated a scoring method for assessing degree of liver dysfunctionality based on the values of bilirubin, creatinine and INR. The herbal formulation in comparison to prednisone successfully restored the liver dysfunction index to low risk. The liver cytology showed a decline in the hepatocyte cell death that further corroborated the promising curative potential of Livogrit.

Biliary Epithelial Senescence in Cellular Rejection Following Live Donor Liver Transplantation.

Background: As with the hepatocytes, cholangiocyte senescence can also easily be detected in damaged small bile ducts and bile ductules during liver disease affecting the biliary system and cholangiocytes. Despite cellular senescence being a feature of chronic progressive cholangiopathies in adults, only a few studies have investigated its role in liver transplant rejection. Method: Transplant biopsies displaying features of rejection were reviewed and classified based on the type of rejection and the time since transplantation. An immunohistochemistry panel has been applied for 3 senescent cell markers (p53, p21, p16). Results: Immunohistochemical expression analysis for the biliary senescence markers (53 biopsies) was done in the post-transplantation periods (Group 1-4) for the cases with the histologically proven diagnosis of rejection. In post-transplant group 1 (<3 months), group 2 (3-6 months), group 3 (6-12 months) and group 4 (>12 months), any 2 senescent markers' positivity was noted in 5/14 (35.7%), 8/13 (61.5%), 16/17 (94.1%) and 9/9 (100%) biopsies respectively and were comparable in all four groups (P = 0.001). A comparison of early biopsies (Group1; 3 months) and late biopsies (Group 2,3&4; >3 months) revealed significantly higher expression in late biopsies (>3 months) (P = 0.001 for any two markers). In ACR, LAR, ECR, and CR/DR any two senescent markers were positive in 14/28 (50%), 12/13 (92.3%) cases, 9/9 (100%), and 3/3cases (100%). Senescent markers (any two) were comparable in all four histological groups (P < 0.001).LAR group had increased expression (P = 0.009 for any two markers and 0.001 for all three markers) and has increased progression to CR (P = 0.019) as compared to ACR. Conclusion: This study on a large number of LDLT allograft biopsies demonstrates the role of biliary senescence in rejection and suggests a pathobiological role for senescence in the poor prognosis seen in late acute cellular rejection and chronic rejection.
