RESUMEN

BACKGROUND & AIMS: Covert hepatic encephalopathy (CHE) is associated with poor outcomes but is often not diagnosed because of the time requirement. Psychometric hepatic encephalopathy score (PHES) is the gold standard against which EncephalApp Stroop has been validated. However, EncephalApp (5 runs each in "Off" and "On" state) can take up to 10 minutes. This study sought to define the smallest number of EncephalApp runs needed for comparable accuracy to the total EncephalApp using CHE on PHES as gold standard. METHODS: A derivation and a validation cohort of outpatients with cirrhosis who underwent PHES (gold standard) and total EncephalApp was recruited. Data were analyzed for individual runs versus total EncephalApp time versus PHES-CHE. The derivation cohort (n = 398) was split into training (n = 299) and test (n = 99) sets. From the training data set a regression model was created with age, gender, education, and various sums of the "Off" settings. After this, a K-fold cross-validation on the test dataset was performed for both total EncephalApp time and individual Off runs and for the validation cohort. RESULTS: In both cohorts, Off runs 1 + 2 had statistically similar area under the receiver operating curve and P value to the total EncephalApp for PHES-CHE prediction. The adjusted (age, gender, education) regression formula from the derivation cohort showed an accuracy of 84% to diagnose PHES-CHE in the validation cohort. Time for CHE diagnosis decreased from 203.7 (67.82) to 36.8 (11.25) seconds in the derivation and from 178.2 (46.19) to 32.9 (9.94) seconds in the validation cohort. CONCLUSIONS: QuickStroop, which is completed within 1 minute, gives an equivalent ability to predict CHE on the gold standard compared with the entire EncephalApp time.

RESUMEN

Chronic liver disease is reaching epidemic proportions with the increasing prevalence of obesity, nonalcoholic liver disease, and alcohol overuse worldwide. Most patients are not candidates for liver transplantation even if they have end-stage liver disease. There is growing evidence of a gut microbial basis for many liver diseases, therefore, better diagnostic, prognostic, and therapeutic approaches based on knowledge of gut microbiota are needed. We review the questions that need to be answered to successfully translate our knowledge of the intestinal microbiome and the changes associated with liver disease into practice.

RESUMEN

The spectrum of hepatic encephalopathy (HE) ranges from overt HE (OHE) to cognitive impairment (ie, covert) HE (CHE).1 The first-line therapy is lactulose, which is titrated to achieve ~2-3 soft/loose daily bowel movements (BM). This metric is considered dogma for practitioners despite erratic results, GI adverse events, and poor tolerance in Western countries.1 There are logistic barriers for the widespread uptake of rifaximin, the second-line therapy. Moreover, although BM frequency-directed dose titration of lactulose is the usual practice, its impact on objective cognitive performance is unclear. Our aim is to determine the impact of BM frequency on cognition in patients with/without prior OHE.

RESUMEN

BACKGROUND AND AIMS: Cirrhosis is associated with changes in intestinal microbiota that can lead to hepatic encephalopathy (HE) and infections, especially with antibiotic-resistant organisms. However, the impact of gut microbial antibiotic resistance gene (ARG) burden on clinical outcomes is unclear. The aims of the study were to determine the impact of ARGs in cirrhosis-related gut metagenome on outcomes and disease progression, study the effect of rifaximin on ARG burden, and compare ARGs in cirrhosis with chronic kidney disease (CKD) and diabetes. METHODS: In outpatients with cirrhosis who underwent metagenomics, we evaluated change in ARG abundances with progression and their multivariable impact on 90-day hospitalizations and deaths over 1 year. We also studied ARGs pre- and 8 weeks post-rifaximin in patients with compensated cirrhosis in an open-label trial. Finally, ARGs from CKD and diabetes studies were compared with cirrhosis on machine learning. RESULTS: A total of 163 patients with cirrhosis (43 compensated, 20 ascites-only, 30 HE-only, 70 both) and 40 controls were included. ARG abundances were higher in cirrhosis versus controls and worsened with advancing cirrhosis severity; 44 patients were hospitalized and 14 died. ARG abundances were associated with hospitalizations and mortality while controlling for cirrhosis complications, medications, and demographics. Rifaximin trial: ARG abundance patterns were minimally affected in 19 patients post-rifaximin. CKD/diabetes comparison: ARG abundance patterns in cirrhosis are distinguishable on machine learning and include more gram-positive ARGs. CONCLUSIONS: Cirrhosis is associated with high gut microbial ARG gene burden compared with controls, which worsens with disease progression and may be different from CKD and diabetes. ARGs are not affected by rifaximin and are associated with hospitalizations and death.

RESUMEN

Acute-on-chronic liver failure (ACLF) is a condition in cirrhosis associated with organ failure (OF) and high short-term mortality. Both the European Association for the Study of the Liver-Chronic Liver Failure (EASL-CLIF) and North American Consortium for the Study of End-Stage Liver Disease (NACSELD) ACLF definitions have been shown to predict ACLF prognosis. The aim of this study was to compare the ability of the EASL-CLIF versus NACSELD systems over baseline clinical and laboratory parameters in the prediction of in-hospital mortality in admitted patients with decompensated cirrhosis. Five NACSELD centers prospectively collected data to calculate EASL-CLIF and NACSELD-ACLF scores for admitted patients with cirrhosis who were followed for the development of OF, hospital course, and survival. Both the number of OFs and the ACLF grade or presence were used to determine the impact of NACSELD versus EASL-CLIF definitions of ACLF above baseline parameters on in-hospital mortality. A total of 1031 patients with decompensated cirrhosis (age, 57 ± 11 years; male, 66%; Child-Pugh-Turcotte score, 10 ± 2; Model for End-Stage Liver Disease [MELD] score, 20 ± 8) were enrolled. Renal failure prevalence (28% versus 9%, P < 0.001) was more common using the EASL-CLIF versus NACSELD definition, but the prevalence rates for brain, circulatory, and respiratory failures were similar. Baseline parameters including age, white cell count on admission, and MELD score reasonably predicted in-hospital mortality (area under the curve, 0.76). The addition of number of OFs according to either system did not improve the predictive power of the baseline parameters for in-hospital mortality, but the presence of NACSELD-ACLF did. However, neither system was better than baseline parameters in the prediction of 30- or 90-day outcomes. The presence of NACSELD-ACLF is equally effective as the EASL-CLIF ACLF grade, and better than baseline parameters in the prediction of in-hospital mortality in patients with cirrhosis, but not superior in the prediction of longer-term 30- or 90-day outcomes.

RESUMEN

OBJECTIVE: Altered bacterial composition is associated with disease progression in cirrhosis but the role of virome, especially phages, is unclear. DESIGN: Cross-sectional and pre/post rifaximin cohorts were enrolled. Cross-sectional: controls and cirrhotic outpatients (compensated, on lactulose (Cirr-L), on rifaximin (Cirr-LR)) were included and followed for 90-day hospitalisations. Pre/post: compensated cirrhotics underwent stool collection pre/post 8 weeks of rifaximin. Stool metagenomics for bacteria and phages and their correlation networks were analysed in controls versus cirrhosis, within cirrhotics, hospitalised/not and pre/post rifaximin. RESULTS: Cross-sectional: 40 controls and 163 cirrhotics (63 compensated, 43 Cirr-L, 57 Cirr-LR) were enrolled. Cirr-L/LR groups were similar on model for end-stage liver disease (MELD) score but Cirr-L developed greater hospitalisations versus Cirr-LR (56% vs 30%, p=0.008). Bacterial alpha/beta diversity worsened from controls through Cirr-LR. While phage alpha diversity was similar, beta diversity was different between groups. Autochthonous bacteria linked negatively, pathobionts linked positively with MELD but only modest phage-MELD correlations were seen. Phage-bacterial correlation network complexity was highest in controls, lowest in Cirr-L and increased in Cirr-LR. Microviridae and Faecalibacterium phages were linked with autochthonous bacteria in Cirr-LR, but not Cirr-L hospitalised patients had greater pathobionts, lower commensal bacteria and phages focused on Streptococcus, Lactococcus and Myoviridae. Pre/post: No changes in alpha/beta diversity of phages or bacteria were seen postrifaximin. Phage-bacterial linkages centred around urease-producing Streptococcus species collapsed postrifaximin. CONCLUSION: Unlike bacteria, faecal phages are sparsely linked with cirrhosis characteristics and 90-day outcomes. Phage and bacterial linkages centred on urease-producing, ammonia-generating Streptococcus species were affected by disease progression and rifaximin therapy and were altered in patients who experienced 90-day hospitalisations.

RESUMEN

INTRODUCTION: We aimed to determine the effect of comorbidities on covert hepatic encephalopathy (CHE) diagnosis and overt hepatic encephalopathy (OHE) development. METHODS: Cirrhotic outpatients underwent CHE testing and 2-year follow-up. Cox regression was performed for time to OHE. In total, 700 patients (60 years, 84% men, model for end-stage liver disease 11) and 33% prior OHE underwent testing and follow-up. RESULTS: Major comorbidities were hypertension (54%), diabetes (35%), and depression (29%). Common medications were proton pump inhibitor (49%), beta-blockers (32%), and opioids (21%). Approximately 90 (40%) prior-OHE patients developed recurrence 93 (30,206) days post-testing predicted only by liverrelated variables. DISCUSSION: Demographics, cirrhosis characteristics, and opioid use, but not other comorbid conditions, were associated with CHE diagnosis and OHE progression.

RESUMEN

Cirrhosis is a debilitating chronic disease with high morbidity and mortality, with the only real cure being liver transplantation (LT). Currently, we allocate organs for transplantation based on the Model for End-Stage Liver Disease-Sodium (MELD-Na) score that does not account for hepatic encephalopathy (HE). HE affects patients, families, and the health care system because of high rates of recurrence and major readmission burden. Moreover, HE casts a long shadow even after LT. Accounting for HE and incorporating it into the current allocation system has many proponents, but the framework to do this is currently lacking because of differences in consensus or in operationalization parameters. We review the latest evidence of the burden of HE, management of HE before and after LT, and evaluate pros and cons of several methods of diagnosing HE objectively to ensure early and equitable access to LT in this underserved population.

RESUMEN

The gut microbiome is altered in cirrhosis. Recent evidence has suggested a key role for the gut microbiota in the progression of cirrhosis and the development of hepatocellular carcinoma (HCC). We studied the differences in the microbial composition in patients with cirrhosis with prior and future HCC in the context of other complications (eg, infections, hepatic encephalopathy). The following 2 cohorts were recruited prospectively: the prior HCC cohort, in which outpatients with HCC within 2 years were age-matched, sex-matched, and Model for End-Stage Liver Disease (MELD) score-matched with those without HCC; and the future HCC cohort, in which patients were followed for 2 years and divided into future HCC versus no HCC after age, sex, and MELD-score matching and other complications were also recorded. Microbiota composition and predicted function were analyzed with ribosomal RNA sequencing and Phylogenetic Investigation of Communities by Reconstruction of Unobserved States (PiCRUST)and compared between (1) prior HCC versus none and (2) future HCC versus none, and in the future cohort, comparisons were also made between those patients who developed (1) HCC only versus without complications, (2) HCC only versus non-HCC complications only, and (3) HCC + other complications versus non-HCC complications only. A total of 142 men (76 total in the prior cohort [38 with/38 without HCC] and 66 total in the future cohort [33 with/33 without future HCC]) were included. The groups had similar etiology, lactulose/rifaximin/proton pump inhibitor use, diabetes mellitus, and non-HCC complications. Microbial diversity was similar between prior HCC/not or future HCC/not. On DESeq2 higher Clostridium sensu stricto and Anaerotruncus were significantly associated with protection from HCC, whereas the reverse was seen with Raoultella and Haemophilus regardless of prior/future HCC comparisons. Functions focused on urea cycle, bioenergetics, tryptophan, and toluene metabolism were different between the groups. Rothia was specific for other complications. Despite age, sex, and MELD-score matching and accounting for other complications, gut microbiota composition and the predicted function are different in men with cirrhosis with and without prior HCC and can be extended toward future HCC development.

RESUMEN

BACKGROUND: Cirrhosis is associated with poor health-related quality of life (HRQOL), cognitive dysfunction (CD), and lack of coordination leading to falls. Tandem gait (TG; heel-toe) can be used to assess coordination. The impact and relationship between CD, TG and falls pre-/post-liver transplant (LT) is unclear. We aimed to determine the impact of LT on CD, abnormal TG, and HRQOL in cirrhosis. METHODS: We analyzed patients who underwent complete neurological examination, cognitive testing by psychometric hepatic encephalopathy score (PHES), and HRQOL assessment using sickness impact profile (SIP). All patients were followed for 1 post-LT visit at 6 or 12 months post-LT for clinical course and falls. Change in CD, TD, and falls pre-/post-LT were compared. RESULTS: Off 131 recruited, 61 patients completed all visits. Majority were men (84%), with HCV etiology (34%). Pre-LT: Abnormal TG trended towards increased falls (OR 3.3, P = 0.08). Forty-nine % had abnormal TG, 61% had CD, 32.7% had CD + abnormal TG, 62% had prior OHE, and 14.7% had falls. Abnormal and normal TG patients had similar ages, BMI, sex, education level, and MELD scores. Abnormal TG group had higher prior overt HE (P = 0.03) and worse physical SIP score (P = 0.008). Post-LT: There was sustained improvement in CD, HRQOL, falls, and TG post-LT more at 12 than 6 months in all patients. Patients who had abnormal TG pre-LT continued to have a worse PHES (P = 0.0064) and physical SIP score (P = 0.008) compared to normal pre-LT TG patients. CONCLUSION: After LT, there is a sustained improvement in coordination measured via tandem gait, accompanied by a lower rate of falls.

RESUMEN

BACKGROUND: Health information technology (IT) interventions to decrease readmissions for cirrhosis may be limited by patient-associated factors. OBJECTIVE: The aim of this study was to determine perspectives regarding adoption versus refusal of health IT interventions among patient-caregiver dyads. METHODS: Inpatients with cirrhosis and their caregivers were approached to participate in a randomized health IT intervention trial requiring daily contact with research teams via the Patient Buddy app. This app focuses on ascites, medications, and hepatic encephalopathy over 30 days. Regression analyses for characteristics associated with acceptance were performed. For those who declined, a semistructured interview was performed with themes focused on caregivers, protocol, transport/logistics, technology demands, and privacy. RESULTS: A total of 349 patient-caregiver dyads were approached (191 from Virginia Commonwealth University, 56 from Richmond Veterans Affairs Medical Center, and 102 from Mayo Clinic), 87 of which (25%) agreed to participate. On regression, dyads agreeing included a male patient (odds ratio [OR] 2.08, P=.01), gastrointestinal bleeding (OR 2.3, P=.006), or hepatic encephalopathy admission (OR 2.0, P=.01), whereas opioid use (OR 0.46, P=.03) and alcohol-related etiology (OR 0.54, P=.02) were associated with refusal. Race, study site, and other admission reasons did not contribute to refusing participation. Among the 262 dyads who declined randomization, caregiver reluctance (43%), perceived burden (31%), technology-related issues (14%), transportation/logistics (10%), and others (4%), but not privacy, were highlighted as major concerns. CONCLUSIONS: Patients with cirrhosis admitted with hepatic encephalopathy and gastrointestinal bleeding without opioid use or alcohol-related etiologies were more likely to participate in a health IT intervention focused on preventing readmissions. Caregiver and study burden but not privacy were major reasons to decline participation. Reducing perceived patient-caregiver burden and improving communication may improve participation.

RESUMEN

Gender differences in the natural history of chronic liver disease have been well-described. Women have lower rates of chronic liver disease and slower fibrosis progression, yet higher rates of waitlist mortality.1,2 Although previous studies have identified several clinical factors including height and creatinine that explain some of this transplant disparity, most have used data from administrative records, which are limited in their ability to identify clinically relevant differences and opportunities for intervention to reduce disparities.3-5 Additionally, most studies have focused on the period between waitlist and transplant, failing to capture gender differences in access to transplant.3,6 In the present study, we took advantage of a multicenter inpatient cohort with granular clinical data to characterize how women and men with cirrhosis differ, to stimulate future research aimed at reducing the well-established gender disparity in liver transplantation.

RESUMEN

BACKGROUND & AIMS: Patients with cirrhosis are growing older. The overlap between minimal hepatic encephalopathy (MHE) and predementia mild cognitive impairment (MCI) could affect quality of life (QOL). We investigated the performance of elderly patients with cirrhosis on tests for MHE and MCI and their effects on QOL. METHODS: We recruited outpatients with cirrhosis (n = 109) and without cirrhosis (controls, n = 100), 65 years or older, at 4 centers (derivation cohort). All study participants were assessed for psychometric hepatic encephalopathy score (PHES), EncephalApp score, and QOL. MCI was tested in patients with cirrhosis using the repeatable battery for assessment of neuropsychological status and assigned to the following groups: unimpaired, MCI only, MHE only, and MCI+MHE. We created adjusted norms to detect MHE using PHES and EncephalApp scores from the controls. Findings were validated using data from a separate cohort of 77 patients with cirrhosis (mean age, 69.49 ± 4.36 y; 72% men) at the same study sites. RESULTS: Controls were older but were more educated, performed better cognitively, and had better QOL. Among patients with cirrhosis, age, education, model for end-stage liver disease score, EncephalApp score, and QOL were similar, but PHES and repeatable battery for assessment of neuropsychological status differed among sites. In the derivation cohort, the presence of MHE, with or without MCI, was associated with poor QOL, which was lowest in the MCI+MHE group. When we adjusted for age, sex, and education, 49% of patients with cirrhosis had MHE based on the EncephalApp and 8% had MHE based on the PHES. A similar pattern (49% MHE based on EncephalApp and 6% MHE based on PHES) was found in a validation cohort. CONCLUSIONS: In a multicenter study of patients with cirrhosis (>65 y) and controls, the presence of MHE, regardless of MCI, was associated with poor cognition and QOL. We created adjusted norms that defined the high sensitivity of EncephalApp for the detection of MHE in older individuals and validated it in a separate cohort.

RESUMEN

Hepatic encephalopathy (HE) can cause major morbidity despite standard of care (SOC; rifaximin/lactulose). Fecal microbial transplant (FMT) enemas postantibiotics are safe, but the effect of FMT without antibiotics using the capsular route requires investigation. The aim of this work was to determine the safety, tolerability, and impact on mucosal/stool microbiota and brain function in HE after capsular FMT in a randomized, single-blind, placebo-controlled clinical trial in Virginia. Patients with cirrhosis with recurrent HE with MELD (Model for End-Stage Liver Disease) <17 on SOC were randomized 1:1 into receiving 15 FMT capsules versus placebo from a single donor enriched in Lachnospiraceae and Ruminococcaceae. Endoscopies with duodenal and sigmoid biopsies, stool analysis, cognition, serum lipopolysaccharide-binding protein (LBP), and duodenal antimicrobial peptide (AMP) expression at baseline were used. Clinical follow-up with SOC maintenance was performed until 5 months. FMT-assigned patients underwent repeat endoscopies 4 weeks postenrollment. Twenty subjects on lactulose/rifaximin were randomized 1:1. MELD score was similar at baseline (9.6 vs. 10.2) and study end (10.2 vs. 10.5). Six patients in the placebo group required hospitalizations compared to 1 in FMT, which was deemed unrelated to FMT. Infection/HE episodes were similar between groups. Baseline microbial diversity was similar in all tissues between groups. Post-FMT, duodenal mucosal diversity (P = 0.01) increased with higher Ruminococcaceae and Bifidobacteriaceae and lower Streptococcaceae and Veillonellaceae. Reduction in Veillonellaceae were noted post-FMT in sigmoid (P = 0.04) and stool (P = 0.05). Duodenal E-cadherin (P = 0.03) and defensin alpha 5 (P = 0.03) increased whereas interleukin-6 (P = 0.02) and serum LBP (P = 0.009) reduced post-FMT. EncephalApp performance improved post-FMT only (P = 0.02). Conclusion: In this phase 1 study, oral FMT capsules are safe and well tolerated in patients with cirrhosis and recurrent HE. FMT was associated with improved duodenal mucosal diversity, dysbiosis, and AMP expression, reduced LBP, and improved EncephalApp performance. Further studies are needed to prove efficacy.

RESUMEN

In patients with cirrhosis, the gut microbiome are affected by multiple gut and systemic alterations. These changes lead to dysbiosis in the microbiota of different parts of the body, resulting in inflammation. The constant immune stimulation resulting in part from dysbiosis is associated with morbidity in patients with cirrhosis. Dysbiosis as a dynamic event worsens with decompensation such as with hepatic encephalopathy, infections or acute-on-chronic liver failure (ACLF). These microbial patterns could be applied as diagnostic and prognostic measures in cirrhosis in the outpatient and inpatient setting. Current therapies for cirrhosis have differing impacts on gut microbial composition and functionality. Dietary modifications and the oral cavity have emerged as newer targetable factors to modulate the microbiome, which could affect inflammation and, potentially improve outcomes. Additionally, fecal microbial transplant is being increasingly studied to provide compositional and functional modulation of the microbiome. Ultimately, a combination of targeted therapies may be needed to provide an optimal gut milieu to improve outcomes in cirrhosis.

RESUMEN

OBJECTIVES: Minimal hepatic encephalopathy (MHE) is epidemic in cirrhosis, but testing strategies often have poor concordance. Altered gut/salivary microbiota occur in cirrhosis and could be related to MHE. Our aim was to determine microbial signatures of individual cognitive tests and define the role of microbiota in the diagnosis of MHE. METHODS: Outpatients with cirrhosis underwent stool collection and MHE testing with psychometric hepatic encephalopathy score (PHES), inhibitory control test, and EncephalApp Stroop. A subset provided saliva samples. Minimal hepatic encephalopathy diagnosis/concordance between tests was compared. Stool/salivary microbiota were analyzed using 16srRNA sequencing. Microbial profiles were compared between patients with/without MHE on individual tests. Logistic regression was used to evaluate clinical and microbial predictors of MHE diagnosis. RESULTS: Two hundred forty-seven patients with cirrhosis (123 prior overt HE, MELD 13) underwent stool collection and PHES testing; 175 underwent inhibitory control test and 125 underwent Stroop testing. One hundred twelve patients also provided saliva samples. Depending on the modality, 59%-82% of patients had MHE. Intertest Kappa for MHE was 0.15-0.35. Stool and salivary microbiota profiles with MHE were different from those without MHE. Individual microbiota signatures were associated with MHE in specific modalities. However, the relative abundance of Lactobacillaceae in the stool and saliva samples was higher in MHE, regardless of the modality used, whereas autochthonous Lachnospiraceae were higher in those without MHE, especially on PHES. On logistic regression, stool and salivary Lachnospiraceae genera (Ruminococcus and Clostridium XIVb) were associated with good cognition independent of clinical variables. DISCUSSION: Specific stool and salivary microbial signatures exist for individual cognitive testing strategies in MHE. The presence of specific taxa associated with good cognitive function regardless of modality could potentially be used to circumvent MHE testing.

RESUMEN

Malnutrition is widely prevalent in cirrhosis patients, which can worsen sarcopenia, hepatic encephalopathy (HE), and overall prognosis. We aimed to define the frequency of nutritional assessments of patients with cirrhosis in retrospective and prospective (after educational training) cohorts and to evaluate prospective changes along with their effects on 90-day readmissions. This study was conducted in 2 phases. Retrospectively, records of hospitalized patients with cirrhosis from the university and Veterans Affairs Medical Center (VAMC) settings were reviewed to assess nutritional status, if a nutrition consultation occurred, the number of days patients were nil per os (npo) and received inadequate nutrition, and if nutritional management was guideline directed. In the prospective phase, after dedicated educational efforts directed at the stakeholders regarding nutritional guidelines for patients with cirrhosis, subsequently hospitalized cirrhosis patients had nutritional and 90-day readmission data collected for comparison between groups. In total, 279 patients were included in the retrospective phase (150 university/129 VAMC), and 102 VAMC patients were in the prospective phase. Cirrhosis severity, reason for admission, and hospital course were similar between groups regardless of cohort, ie, prospective versus retrospective or VAMC versus university. The prospective group had significantly more nutritional consultations and assessments (74.5% versus 40.1%; P < 0.001) compared with the retrospective group regardless of comparisons between the VAMC and university cohorts. Both groups had a similar number of days npo, but the prospective group had fewer days of inadequate nutrition. The 90-day readmission rate was significantly lower in the prospective group versus the retrospective group (39.4% versus 28.4%; P = 0.04), which was associated with greater nutrition outpatient follow-up. In conclusion, nutritional consultation rates in inpatients with cirrhosis can be significantly improved after educational intervention and is associated with lower 90-day readmission rates.

RESUMEN

The relative ranking of cirrhosis-related deaths differs between high-/middle-income countries. Gut microbiome is affected in cirrhosis and is related to diet. Our aim was to determine the effect of differing dietary habits on gut microbiota and clinical outcomes. Outpatient compensated/decompensated patients with cirrhosis and controls from Turkey and the United States underwent dietary and stool microbiota analysis. Patients with cirrhosis were followed till 90-day hospitalizations. Shannon diversity and multivariable determinants (Cox and binary logistic) of microbial diversity and hospitalizations were studied within/between groups. Two hundred ninety-six subjects (157 U.S.: 48 controls, 59 compensated, 50 decompensated; 139 Turkey: 46 controls, 50 compensated, 43 decompensated) were included. Patients with cirrhosis between cohorts had similar Model for End-Stage Liver Disease (MELD) scores. American patients with cirrhosis had more men, greater rifaximin/lactulose use, and higher hepatitis C/alcohol etiologies. Coffee intake was higher in Americans whereas tea, fermented milk, and chocolate intake were higher in Turkey. The entire Turkish cohort had a significantly higher microbial diversity than Americans, which did not change between their controls and patients with cirrhosis. In contrast, microbial diversity changed in the U.S.-based cohort and was the lowest in decompensated patients. Coffee, tea, vegetable, chocolate, and fermented milk intake predicted a higher diversity whereas MELD score, lactulose use, and carbonated beverage use predicted a lower microbial diversity. The Turkish cohort had a lower risk of 90-day hospitalizations. On Cox and binary logistic regression, microbial diversity was protective against 90-day hospitalizations, along with coffee/tea, vegetable, and cereal intake. CONCLUSION: In this study of patients with cirrhosis and healthy controls from the United States and Turkey, a diet rich in fermented milk, vegetables, cereals, coffee, and tea is associated with a higher microbial diversity. Microbial diversity was associated with an independently lower risk of 90-day hospitalizations. (Hepatology 2018;68:234-247).

RESUMEN

Cirrhosis is associated with a systemic proinflammatory milieu, endotoxemia, and gut dysbiosis. The oral cavity could be an additional source of inflammation. We aimed to determine the effect of periodontal therapy in cirrhosis through evaluating endotoxemia, inflammation, cognition, and quality of life (QOL). Age-matched cirrhotic and noncirrhotic subjects exhibiting chronic gingivitis and/or mild or moderate periodontitis underwent periodontal therapy with follow-up at 30 days. Saliva/stool for microbial composition and serum for Model for End-stage Liver Disease (MELD) score, endotoxin and lipopolysaccharide binding protein (LBP) and immune-inflammatory markers (IL-1ß; IL-6; histatins 1, 3, 5; and lysozyme) were collected at baseline and day 30. The cognitive function and QOL were also evaluated similarly. A separate group of cirrhotic patients were followed for the same duration without periodontal therapy. Cirrhotics, especially those with hepatic encephalopathy (HE), demonstrated improved dysbiosis in stool and saliva, and improved endotoxin, LBP, and salivary and serum inflammatory mediators following periodontal therapy. These parameters, which were higher in HE at baseline, became statistically similar posttherapy. Pretherapy vs. posttherapy QOL and cognition also improved in HE patients following oral interventions. On the other hand, LBP and endotoxin increased over time in cirrhotic patients not receiving therapy, but the rest of the parameters, including microbiota remained similar over time in the no-therapy group. This proof-of-concept study demonstrates that periodontal therapy in cirrhosis, especially in those with HE, is associated with improved oral and gut dysbiosis, systemic inflammation, MELD score, and cognitive function, which was not observed in those who did not receive therapy over the same time period. NEW & NOTEWORTHY Systematic periodontal therapy in cirrhotic outpatients improved endotoxemia, as well as systemic and local inflammation, and modulated salivary and stool microbial dysbiosis over 30 days. This was associated with improved quality of life and cognition in patients with prior hepatic encephalopathy. In a cirrhotic group that was not provided periodontal therapy, there was an increase in endotoxin and lipopolysaccharide binding protein in the same duration. The oral cavity could be an important underdefined source of inflammation in cirrhosis.

RESUMEN

BACKGROUND & AIMS: The neutrophil to lymphocyte ratio (NLR) is a biomarker of immune dysregulation in patients with cirrhosis and is inexpensive to measure. We investigated the association between NLR and mortality in hospitalized patients with cirrhosis at 4 liver transplant centers, controlling for severity of acute-on-chronic liver failure (ACLF). METHODS: We performed a retrospective study using data from the North American Consortium for the Study of End-stage Liver Disease on patients with index hospitalizations for cirrhosis from December 2011 through December 2016. We collected data on patient demographics, NLR, model for end-stage liver disease (MELD) scores, serum levels of Na, cirrhosis stages, infections, hepatocellular carcinomas, and ACLF severity (based on number of organ failures). Competing risk regression analysis evaluated mortality within 1 year after hospital discharge, accounting for competing events (liver transplant). RESULTS: At admission, the patients' mean age was 57 years, mean MELD score was 21, and mean serum level of Na was 134 mmol/L. Sixty-eight patients had no organ failure, 21 patients had 1 organ failures, 7 patients had 2 organ failures, 4 patients had 3 organ failures, and 1 patient had 4 organ failures; 36% of the patients had confirmed or suspected infections. In univariate models, risk of death associated with increasing NLR, up to a value of 8 (hazard ratio [HR]= 1.14; 95% CI, 1.07-1.20; P < .001), and NLR quartile (for NLR range of 3-5, HR = 2.17; for NLR range of >5-9, HR=2.46; for NLR quartile >9, HR=2.84 vs the lowest quartile [NLR<3]) (P ≤ .001). The NLR remained statistically significant in multivariable models, adjusting for age, MELD score, hepatocellular carcinoma, and ACLF severity. Additionally, NLR was a statistically significant independent predictor of length of index hospital stay and mortality within 90 days after discharge. CONCLUSION: In a retrospective analysis of patients with cirrhosis, we found NLR to associate with death within 1 year after non-elective hospitalization. In these patients, the risk of death associated with acute immune dysregulation persists long after their initial hospitalization.
