Intragastric Balloon in Obese Compensated Nonalcoholic Steatohepatitis Cirrhosis Patients Is Safe and Achieves Significant Weight Reduction at 6-Months.

BACKGROUND AND STUDY AIMS: Weight reduction is the mainstay treatment for Nonalcoholic steatohepatitis (NASH). intragastric balloon (IGB) placement has proven benefit in terms of weight reduction. The aim of the present study is to assess the safety and efficacy of IGB placement in compensated NASH cirrhosis. PATIENTS AND METHODS: Nonalcoholic steatohepatitis cirrhosis patients with CTP ≤ 7, BMI of > 30, and who were unable to achieve weight reduction with lifestyle modification in past 3 months were prospectively enrolled. Spatz3™ adjustable gastric balloon was placed endoscopically. Primary objective was to determine efficacy in weight loss at 6 months, with secondary objectives of reduction in hepatic venous pressure gradient (HVPG), liver fat (controlled attenuation parameter, CAP), liver stiffness measurement (LSM) and clinical events as well as the tolerability and adverse events due to IGB placement. RESULTS: Altogether 56 cirrhosis patients, with a baseline BMI of 35.24 ± 3.92 and a CTP score of 6.27 ± 1.28 underwent IGB placement. The absolute weight reduction achieved was 15.88 kg (- 16.46%) and reduction in BMI was - 10.1% at 6 months. The percentage total body weight loss of ≥ 10% was achieved in 31 (55.35%) patients. The reduction in HVPG at 6-months was 11.12% (n = 16, 14.18 ± 2.12 to 12.60 ± 1.67 mmHg). The mean reduction in LSM was 28.6% and in CAP was 10.09%. Three (5.36%) patients required removal of IGB before 6-months due to persisting vomiting. No patient developed new-onset decompensation or any serious adverse event. CONCLUSION: IGB placement is a safe, well tolerated and effective option for reduction in weight and portal pressure in compensated obese cirrhosis patients.

Defects in energy metabolism are associated with functional exhaustion of bone marrow mesenchymal stem cells in cirrhosis.

OBJECTIVES: Cellular and functional exhaustion of bone marrow mesenchymal stem cells (BM-MSC) is significantly associated with the loss of HSCs and hepatic osteodystrophy in cirrhosis. The molecular mechanisms underlying the dysfunction of BM-MSCs are not well understood. We investigated the underlying mechanisms of cellular and functional exhaustion of BM-MSCs in cirrhosis. METHODS: The MSCs were isolated retrospectively from bone marrow of decompensated alcoholic cirrhosis patients {(Trial registration: ClinicalTrials.gov NCT01902511) (n=10; MELD=16.2±2.3; CTP=8.7±2.3)} and age and gender-matched healthy controls (n=8). Global gene expression profile of healthy bone marrow MSCs (hBM-MSCs) and cirrhosis patients BM-MSCs (cBM-MSCs) were done by mRNA sequencing. XFe24-bioanalyzer analyzed the bioenergetic potential of cells. Level of different cytokines and growth factors in BM-plasma and MSCs secretome were analyzed by Luminex-based bead array. RESULTS: Analysis of differentially expressed genes showed significant (P<0.01) up-regulation of genes associated with ubiquitination and catabolism of proteins; TNF signaling, insulin resistance, and down-regulation of genes associated with DNA repair, protein processing, cell cycle, and mitochondrial respiration in cBM-MSCs in comparison to hBM-MSCs. Compared to hBM-MSCs, cBM-MSCs showed a significant defect in glycolysis due to insulin resistance and poor glucose uptake (P=0.002). This led to compromised self-renewal capacity and cellular loss of MSCs in cirrhosis. cBM-MSCs also showed a significant impairment in Oxidative phosphorylation (OXPHOS) due to mitochondrial dysfunction leading to defects in the osteogenic differentiation with early aging and senescence. CONCLUSION: Compromised energy metabolism due to inflammatory and metabolic stress-induced insulin resistance underlies the cellular and functional exhaustion of BM-MSCs in cirrhosis.

Tinospora Cordifolia (Giloy)-Induced Liver Injury During the COVID-19 Pandemic-Multicenter Nationwide Study From India.

Tinospora cordifolia (Giloy) is an herbal supplement commonly used in the Indian alternative medicine system Ayurveda. This herb has been promoted to the public in India as an immune booster to prevent novel coronavirus disease 2019. However, small reports have recently shown an association between Giloy use and the development of herb-induced liver injury (HILI) with autoimmune features in some patients. This large retrospective Indian multicenter study spanning 13 centers at nine locations was designed to identify features and outcomes of HILI temporally associated with Giloy use. Chemical and toxicological analyses of retrieved Giloy samples using state-of-the-art methods were also performed. We report 43 patients, of whom more than half were female, with a median time from initial Giloy consumption to symptom onset of 46 days. Patients presented with acute hepatitis, acute worsening of chronic liver disease (CLD, the most common clinical presentation), or acute liver failure. Causality assessment revealed probable liver injury in 67.4%. The most common autoantibody detected was anti-nuclear antibody. Liver biopsy in a subset revealed HILI associated with autoimmune features and hepatocyte and canalicular cholestasis and neutrophilic and eosinophilic infiltration. Conclusion: Giloy is associated with acute hepatitis with autoimmune features and can unmask autoimmune hepatitis (AIH) in people with silent AIH-related CLD. Further studies on the safety (and efficacy) of untested but heavily promoted herbals in alternative systems of medicine are an unmet need in the interests of public health and are especially important during this global health emergency.

Prevalence of and Factors Associated with Sleep-Wake Abnormalities in Patients with Cirrhosis.

BACKGROUND & AIMS: Sleep-wake abnormalities [poor nighttime sleep and excessive daytime sleepiness (EDS)] are common in patients with cirrhosis. The aim of this study was to assess the prevalence of sleep-wake abnormalities and clinical factors associated with these abnormalities in a group of patients with cirrhosis. METHODS: 1098 patients with cirrhosis [Child Turcotte Pugh (CTP) class A, 22.2%; CTP class B, 29.2% and CTP class C, 48.6%], with either no ascites or mild ascites controlled on diuretics, and no history of or current overt hepatic encephalopathy were included in the study. RESULTS: Poor nighttime sleep and EDS were found in 569 (51.8%) and 489 (44.5%) patients respectively. On multivariate analysis, factors associated with poor nighttime sleep were CTP class C (vs. class A), presence of minimal hepatic encephalopathy (MHE), intermediate or evening type of diurnal preference category (vs. morning type), high risk for obstructive sleep apnea (OSA), diuretic use, presence of major depression, and presence of generalized anxiety disorder (GAD). Factors associated with EDS on multivariate analysis were CTP class B and C (vs. class A), intermediate or evening type of diurnal preference category (vs. morning type), high risk for OSA, presence of major depression, and presence of GAD. CONCLUSIONS: Sleep-wake abnormalities are common in patients with cirrhosis. CTP status, diurnal preference chronotype, risk of OSA, major depression and GAD are associated with both poor nighttime sleep and EDS. MHE and diuretic use are associated with poor nighttime sleep, but not with EDS.

Omega-3 fatty acid lipid emulsions are safe and effective in reducing endotoxemia and sepsis in acute-on-chronic liver failure: An open-label randomized controlled trial.

BACKGROUND AND AIM: Sepsis is an important determinant of the outcome of acute-on-chronic liver failure (ACLF) patients. Omega-3 fatty acids (FAs) are known to suppress inflammation, reduce morbidity, and mortality in postoperative and critically ill patients. We aimed to evaluate the effect of intravenous omega-6 and omega-3 FA lipid emulsions in ACLF patients. METHODS: Ninety ACLF patients were randomly allocated to three groups: Gr. A received no lipid emulsions, Gr. B received omega-6 FAs, and Gr. C received omega-3 FAs. The primary and secondary aims were to compare the effects of lipid emulsions on immune modulation, the incidence of bacterial sepsis, and mortality at day 28. RESULTS: The baseline characteristics of the patients were comparable. Serum endotoxin levels remained suppressed by 22% in Gr. C compared with a 4% and 12% rise in Gr. B and A (P < 0.001). Omega-3 FAs also suppressed C-reactive protein levels and neutrophil-to-lymphocyte ratio in Gr. C. Compared with Gr. A, omega-3 FAs reduced sepsis by 86% (HR, 0.14; 95% CI 0.04-0.43; P < 0.001). Omega-3 FAs significantly increased the expression of TLR2 and TLR4 on both CD14+ and CD16+ monocytes, and TLR4, on macrophages and neutrophils. There were no serious adverse events, except transient flushing in 20% and 16.6% of patients receiving omega-6 FAs and omega-3 FAs, respectively. CONCLUSION: Omega-3 FAs are safe and effective in reducing systemic inflammation, endotoxemia, and sepsis in patients with ACLF. These lipid emulsions could also be considered as effective sources of immunonutrition in such sick patients.

Pre-existing liver disease is associated with poor outcome in patients with SARS CoV2 infection; The APCOLIS Study (APASL COVID-19 Liver Injury Spectrum Study).

BACKGROUND AND AIMS: COVID-19 is a dominant pulmonary disease, with multisystem involvement, depending upon comorbidities. Its profile in patients with pre-existing chronic liver disease (CLD) is largely unknown. We studied the liver injury patterns of SARS-Cov-2 in CLD patients, with or without cirrhosis. METHODS: Data was collected from 13 Asian countries on patients with CLD, known or newly diagnosed, with confirmed COVID-19. RESULTS: Altogether, 228 patients [185 CLD without cirrhosis and 43 with cirrhosis] were enrolled, with comorbidities in nearly 80%. Metabolism associated fatty liver disease (113, 61%) and viral etiology (26, 60%) were common. In CLD without cirrhosis, diabetes [57.7% vs 39.7%, OR = 2.1 (1.1-3.7), p = 0.01] and in cirrhotics, obesity, [64.3% vs. 17.2%, OR = 8.1 (1.9-38.8), p = 0.002] predisposed more to liver injury than those without these. Forty three percent of CLD without cirrhosis presented as acute liver injury and 20% cirrhotics presented with either acute-on-chronic liver failure [5 (11.6%)] or acute decompensation [4 (9%)]. Liver related complications increased (p < 0.05) with stage of liver disease; a Child-Turcotte Pugh score of 9 or more at presentation predicted high mortality [AUROC 0.94, HR = 19.2 (95 CI 2.3-163.3), p < 0.001, sensitivity 85.7% and specificity 94.4%). In decompensated cirrhotics, the liver injury was progressive in 57% patients, with 43% mortality. Rising bilirubin and AST/ALT ratio predicted mortality among cirrhosis patients. CONCLUSIONS: SARS-Cov-2 infection causes significant liver injury in CLD patients, decompensating one fifth of cirrhosis, and worsening the clinical status of the already decompensated. The CLD patients with diabetes and obesity are more vulnerable and should be closely monitored.

Guillain-Barré syndrome in a patient of acute Hepatitis E virus infection associated with genotype 1: Case report and literature review.

Hepatitis E is a serious public health problem in developing countries. Most of the patients with Hepatitis E virus (HEV) infection present with typical acute hepatitis symptoms. However, in few patients it may lead to complications such as liver failure and extrahepatic symptoms. One of the rare extrahepatic presentations of this infection is neurological complications such as Guillain-Barré syndrome (GBS) which is observed in 5.5% of HEV infected patients (mainly in developed countries). Moreover, only genotype (gt) 3 HEV was found in association with GBS among patients in developed countries whereas molecular characterisation of HEV cases detected from developing countries have not been reported till now. Here, we are reporting a case of GBS as an extrahepatic complication of HEV associated with gt1 identified by molecular characterization by performing PCR of open-reading frame 2 (ORF2) region of HEV. Phylogenetic analysis by maximum likelihood method revealed that HEV gt1 case reported in this paper rooted closely with other HEV gt1 samples from South-Asian countries with high bootstrap values indicative of fully resolved tree.

Effects of zolpidem on sleep parameters in patients with cirrhosis and sleep disturbances: A randomized, placebo-controlled trial.

BACKGROUND/AIMS: The aim of this study was to study the efficacy and safety of zolpidem for sleep disturbances in patients with cirrhosis. METHODS: Fifty-two Child-Turcotte-Pugh (CTP) class A or B cirrhotics with Pittsburgh Sleep Quality Index >5 were randomized to either zolpidem 5 mg daily (n=26) or placebo (n=26) for 4 weeks. RESULTS: The therapy of 4 weeks was completed by 23 patients receiving zolpidem (3 stopped treatment due to excessive daytime drowsiness) and 24 receiving placebo (2 refused to continue the study). In the zolpidem group, after 4 weeks of therapy, there was significant increase in total sleep time (TST) and sleep efficiency compared to baseline and improvement in polysomnographic parameters of sleep initiation and maintenance (i.e., decrease in sleep latency time, decrease in wake time, and decreases in number of arousals and periodic limbs movements per hour of sleep), without any significant change in sleep architecture. CONCLUSION: Four weeks of 5 mg daily zolpidem in CTP class A or B cirrhosis patients with insomnia led to significant increases in TST and sleep efficiency and improvement in polysomnographic parameters of sleep initiation and maintenance without any significant change in sleep architecture.

Early cirrhosis and a preserved bone marrow niche favour regenerative response to growth factors in decompensated cirrhosis.

BACKGROUND: Exogenous growth factor-mobilized bone marrow (BM) stem cells have shown a differential response in the management of decompensated cirrhosis (DC). This study was designed to evaluate potential clinical benefit of adding Erythropoietin (EPO) in granulocyte-colony stimulating factor (G-CSF)-mobilized stem cell therapy, possible mechanisms of regeneration and predictive factors of regenerative response. METHODS: Sixty consecutive DC patients received either G-CSF with EPO (Group A; n = 30) or G-CSF and placebo (Group B; n = 30) for 2 months and were carefully followed up for 1 year. Baseline and post-treatment liver biopsy, BM biopsy and BM aspirate were analysed for fibro-inflammatory and regenerative response and BM hematopoietic reservoir. RESULTS: Addition of EPO to G-CSF showed a significant improvement in Child-Pugh score (P = 0.03) and MELD score (P = 0.003) as compared to G-CSF alone, with reduction in mortality (16.6% vs 36.7%, P = 0.09). The combination arm also demonstrated a decreased incidence of acute kidney injury (P < 0.001), encephalopathy (P = 0.005) and refilling of ascites (P = 0.03). Compared to monotherapy, it increased CD163+ macrophages (P = 0.013), Ki67+ index (P < 0.001) with decrease in α-SMA levels (P < 0.001) in liver tissue. The response was better with grade 1 and 2 than with grade 3 ascites; Child B cirrhosis and MELD < 16. Non-responders had lower hematopoietic stem cells (HSCs) at baseline. On multivariate analysis, the liver disease severity (MELD < 16) and a relatively preserved BM (BM-HSCs > 0.4) predicted therapeutic response (AUROC = 0.82). CONCLUSIONS: Early DC (MELD < 16) patients with mild-moderate ascites and those with a healthy cellular baseline BM respond better to growth factor therapy. Addition of EPO to G-CSF provides better regenerative response than G-CSF monotherapy.

Flare of Autoimmune Hepatitis Causing Acute on Chronic Liver Failure: Diagnosis and Response to Corticosteroid Therapy.

Autoimmune hepatitis (AIH) is considered less common in the Asia Pacific region. Due to this, AIH flare as a cause of acute on chronic liver failure (ACLF) is often overlooked and treatment delayed. We aimed at the defining clinical and histopathological spectrum and role of steroid therapy in AIH-ACLF. Patients with AIH-ACLF, prospectively recruited and followed between 2012 and 2017, were analyzed from the Asian Pacific Association for the Study of the Liver ACLF Research Consortium (AARC) data base. Diagnosis of AIH was confirmed using International Autoimmune Hepatitis Group score or simplified AIH score with histopathological evidence. Of 2,825 ACLF patients, 82 (2.9%) fulfilled criteria of AIH (age 42.1 ± 18.1 years, 70% female). At baseline, mean bilirubin was 18.6 ± 8.2 mg/dL, Child-Turcotte-Pugh score was 11.7 ± 1.4, and Model for End-Stage Liver Disease (MELD) score was 27.6 ± 6.5. Mean immunoglobulin G was 21.61 ± 7.32 g/dL, and this was elevated ≥1.1 times in 97% of cases; 49% were seronegative. Liver histology was available in 90%, with median histological activity index of 10 (interquartile range, 7-12); 90% with moderate to severe interface activity; 56% showing significant parenchymal necrosis (bridging and confluent necrosis); and cirrhosis in 42%. Twenty-eight (34%) patients received steroid therapy and showed shorter intensive care unit (ICU) stay (median 1.5 versus 4 days, P < 0.001) and improved 90-day survival (75% versus 48.1%, P = 0.02) with comparable incidence of sepsis (P = 0.32) compared to those who did not. Patients of advanced age, more severe liver disease (MELD >27; 83.3% sensitivity, 78.9% specificity, area under the receiver operating characteristic curve 0.86), presence of hepatic encephalopathy, and fibrosis grade ≥F3 had an unfavorable response to corticosteroid therapy. Conclusion: AIH presenting as ACLF is not uncommon in Asian patients; a low threshold for liver biopsy is needed to confirm the diagnosis as nearly half the patients are seronegative; early stratification to steroid therapy or liver transplantation (MELD >27, hepatic encephalopathy in ≥F3) would reduce ICU stay and improve outcomes.

A double-blind randomized controlled trial to assess efficacy of bromocriptine in cirrhotic patients with hepatic parkinsonism.

BACKGROUND: Parkinsonism like features can be seen in cirrhotics, possibly related to alterations in brain dopamine metabolism, transport and receptor integrity at basal ganglia. Hepatic parkinsonism is often not suspected and only ammonia-reducing therapies are given to such patients. We investigated the efficacy and safety of bromocriptine, a dopaminergic agent, in patients with hepatic parkinsonism. PATIENTS AND METHODS: Cirrhotics were screened for the presence of extrapyramidal symptoms and were diagnosed as hepatic parkinsonism if any two of tremor, bradykinesia and/or rigidity were present, supported by MRI brain showing T1 hyperintensities in basal ganglia and substantia nigra. Patients were randomized to receive placebo (Gr A, n = 22) or bromocriptine (Gr B, n = 24) for 12 weeks. Complete, partial and non-response were defined as 30%, 10%-30% and <10% reduction,respectively, in Unified Parkinson's Disease Rating Scale motor score. RESULTS: Of 1016 cirrhotics, 50 (4.9%) had hepatic parkinsonism. Patients in two treatment groups were comparable for MELD score, arterial NH3 and frequency of portosystemic shunts. Bromocriptine therapy for 12 weeks resulted in improvement in rigidity, tremors, bradykinesia and gait compared to placebo with complete and partial response in seven vs none (29.1%, 0%, P < 0.01) and 12 vs one (50%, 4.5%, P < 0.01) patients. Prolonged and more severe motor symptoms were associated with non-response to bromocriptine therapy. There were no major side effects in either treatment group. CONCLUSIONS: Hepatic parkinsonism is seen in ~5% cirrhotics. Bromocriptine is a safe and effective therapy for these patients and is more effective in mild to moderate hepatic parkinsonism.

Suboptimal Level of Bone-Forming Cells in Advanced Cirrhosis are Associated with Hepatic Osteodystrophy.

Bone loss is common in advanced cirrhosis, although the precise mechanisms underlying bone loss in cirrhosis are unknown. We studied the profile and functionality of bone-forming cells and bone-building proteins in bone marrow (BM) of individuals with cirrhosis (n = 61) and individuals without cirrhosis as normal controls (n = 50). We also performed dual energy X-ray absorptiometry for clinical correlation. BM mesenchymal cells (MSCs) were analyzed for colony-forming units-fibroblasts and their osteogenic (fibronectin-1 [FN1], insulin-like growth factor binding protein 3 [IGFBP3], collagen type 1 alpha 1 chain [COL1A1], runt-related transcription factor 2 [RUNX2], and alkaline phosphatase, liver [ALPL]) and adipogenic ( adiponectin, C1Q, and collagen domain containing [ADIPOQ], peroxisome proliferator-activated receptor gamma [PPARγ], and fatty acid binding protein 4 [FABP4]) potentials. Colony-forming units-fibroblasts were lower in patients with cirrhosis (P = 0.002) than in controls. Cirrhotic BM-MSCs showed >2-fold decrease in osteogenic markers. Compared to controls, patients with cirrhosis showed fewer osteocytes (P = 0.05), osteoblasts, chondroblasts, osteocalcin-positive (osteocalcin+) area, clusters of differentiation (CD)169+ macrophages (P < 0.001, each), and nestin+ MSCs (P = 0.001); this was more apparent in Child-Turcotte-Pugh (CTP) class C than A (P < 0.001). Multivariate logistic regression showed low nestin+ MSCs (P = 0.004) as a predictor of bone loss. Bone-resolving osteoclasts were comparable among CTP groups, but >2-fold decreased anti-osteoclastic and increased pro-osteoclastic factors were noted in patients with CTP C compared to CTP A. Bone-building proteins (osteocalcin [P = 0.008], osteonectin [P < 0.001], and bone morphogenic protein 2 [P = 0.001]) were decreased while anti-bone repair factors (fibroblast growth factor 23 [P = 0.015] and dipeptidyl peptidase 4 [P < 0.001]) were increased in BM and peripheral blood; this was more apparent in advanced cirrhosis. The dual energy X-ray absorptiometry scan T score significantly correlated with the population of osteoblasts, osteocytes, MSCs, and CD169+ macrophages. Conclusion: Osteoprogenitor cells are substantially reduced in patients with cirrhosis and more so in advanced disease. Additionally, increased anti-bone repair proteins enhance the ineffective bone repair and development of osteoporosis in cirrhosis. Hepatology Communications 2018;0:0-0).

SX-Ella Stent Danis Effectively Controls Refractory Variceal Bleed in Patients with Acute-on-Chronic Liver Failure.

BACKGROUND AND AIMS: Almost 10% of bleeding episodes are refractory to combination of vasoactive agent and endotherapy, and are associated with a mortality up to 50%. Severity of liver disease and high portal pressure are mainly responsible for it. TIPS cannot be used in these patients due to high MELD score. We aimed to evaluate the efficacy of self-expandable DE stents for control of refractory variceal bleeds in patients with ACLF. METHODS: Acute-on-chronic liver failure patients (n = 88, mean age 47.3 ± 10.9 years) with refractory variceal bleeds received either DE stent (Gr. A, n = 35) or continued with repeat endotherapy and vasoactive drug (Gr.B, n = 53). Matching by propensity risk score (PRS) was done to avoid selection bias. Competing risk Cox regression analysis was done to identify event-specific, i.e., gastrointestinal bleed-related death. RESULTS: Majority (78.4%) of patients were alcoholic with MELD score of 45.9 ± 20.1. Control of initial bleeding was significantly more in the DE stent group as compared to controls in both pre-match (89 vs. 37%; p < 0.001) and PRS-matched cohorts (73 vs. 32%; 0.007). Further, bleed-related death was also significantly lower in DE group as compared to controls in both pre-match (14 vs. 64%; p = 0.001) and PRS-matched cohorts (6 vs. 56%; p = 0.001). In a multivariate competing risk Cox model, patients who underwent DE stenting had reduced mortality in both pre-match (p = 0.04, HR 0.36, 95% CI 0.13-0.96) and PRS-matched cohorts (p < 0.001, HR 0.21, 95% CI 0.08-0.51). CONCLUSIONS: Self-expandable DE stents are very effective in control of refractory variceal bleeding and reduced mortality in patients with severe liver failure.

Characterization of body composition and definition of sarcopenia in patients with alcoholic cirrhosis: A computed tomography based study.

BACKGROUND: Alterations in body composition (BC) as loss of fat and muscle mass (sarcopenia) are associated with poor outcome in alcoholic cirrhosis (ALC). Prevalence of sarcopenia depends upon the method of assessment. Computed Tomography (CT) is a gold standard tool for assessing BC. AIM: To characterize BC and define sarcopenia in ALC patients using CT. METHODS: Single slice CT images at L3 vertebrae of healthy controls (HC) - organ transplant donors and ALC patients were analysed to give cross-sectional area of five skeletal muscles normalized for height -skeletal muscle index (SMI; cm2 /m2 ), area of subcutaneous (SAT;cm2 ) and visceral adipose tissue (VAT;cm2 ). Cut-offs for defining sarcopenia was established at 2SD below the mean of HC. HC were compared with Child A-compensated (C) and Child B+C-decompensated (DC) patients. RESULTS: Cut-offs of SMI derived from HC (n = 275; M: 50%; age 32.2 ± 9.8 years; BMI 24.2 ± 3.2 Kg/m2 ) were 36.54 in males and 30.21 in females. Sarcopenia was found in 12.8% of ALC patients [n = 148; C (31.8%): DC (68.2%); M: 100%; age 46.6 ± 9.7 years; BMI 24.5 ± 4.4]. Compared to HC, compensated patients had higher adiposity and comparable muscularity; decompensated patients had significantly lower muscle and also fat mass compared to both HC and compensated patients. HC vs C vs DC: SAT (140 ± 82 vs 177.3 ± 11 vs 112 ± 8.2); VAT (96.5 ± 6.5 vs 154.9 ± 8.7 vs 87.5 ± 6.5) and SMI (52.1 ± 0.9 vs 49.6 ± 1.2 vs 46 ± 0.9). CONCLUSIONS: Compensated ALC have increased adiposity and relatively preserved muscularity but decompensation leads to loss of both muscle and fat mass. Prevalence of sarcopenia, based on derived ethnic cut-offs was 12.8%.

Bone marrow stem cells and their niche components are adversely affected in advanced cirrhosis of the liver.

UNLABELLED: Bone marrow (BM) is a reservoir for immune and hematopoietic cells and critical for tissue repair and regeneration. All of these functions are severely altered in cirrhosis. We investigated the cellular and functional state of BM in cirrhosis patients. We studied the histological, cellular, and molecular changes in BM of cirrhosis patients (n = 168) and controls (n = 44). Hematopoietic stem cells (HSCs) and associated niche cells, mesenchymal stem cells, Schwann cells, neural fibers, and endothelial cells were evaluated by immunohistochemistry. Cytokines and growth factors were analyzed in peripheral blood and BM plasma. Cirrhotic BM showed an inverse correlation between cluster of differentiation 34+HSCs and Model of End-Stage Liver Disease (ρ = -0.582, P < 0.001) and Child's scores (P < 0.038). BMs of cirrhosis patients with higher Model of End-Stage Liver Disease (>15) showed significantly decreased HSCs, mesenchymal stem cells, Schwann cells, and neural fibers; increased interleukin-1ß (P = 0.004), tumor necrosis factor-α (P = 0.040), and interferon-γ (P = 0.03); and decreased oncostatin M (P = 0.04), stem cell factor (P = 0.05), and stromal cell-derived factor 1 (P = 0.03) compared to those with lower Model of End-Stage Liver Disease scores (≤15). The cluster of differentiation 34+ cell population was a predictor for the development of sepsis (P < 0.001), and per unit loss increased the probability of sepsis by 16%. Cirrhosis patients with fewer HSCs had lower hemoglobin (P = 0.05) and platelet counts (P = 0.05) and showed early graft dysfunction. CONCLUSIONS: Increasing severity of cirrhosis causes derangement of the hematopoietic niche and loss of HSCs, contributing to the hematological and immunological dysfunctions and reduced potential for regeneration; restoring BM functions could provide new therapeutic options in cirrhosis. (Hepatology 2016;64:1273-1288).
