Abstract

Conflict of interest: No Introduction and Objectives: Background: Severe alcohol-associated hepatitis (AH) is considered a common precipitant of acute-on-chronic liver failure (ACLF). This study aims to characterize the association between AH and ACLF, focusing on mortality across different ACLF grades. Patients / Materials and Methods: Multicenter prospective cohort study. We included patients admitted with severe AH between 2015–2022. The main outcome was mortality by ACLF grade during admission. The analysis included survival analysis using Cox regression. We adjusted multivariable models based on the main predictors of mortality observed in prior studies. Results and Discussion: We prospectively included 646 patients from 24 centers and 8 countries. Age 49.9±11.7 years, 85.1% of men and 64.4% had a previous diagnosis of cirrhosis. Median MELD at admission was 25 [20-31] points, 46.5% of patients were treated with corticosteroids, and only 2.2% underwent liver transplantation (LT). Around 67.4% of patients fulfilled ACLF criteria: 10.1% grade 1, 19.2% grade 2, and 38.1% grade 3. The most frequent organ dysfunctions were 76.2% liver, 40.8% brain, 43.2% coagulation, 29.6% renal, 29.4% circulatory, and 18.9% lung failure. Survival at 180 days was 77.8% (95%CI: 72.1-82.6%) in those without ACLF grade 3 and 28.0% (95%CI: 20.5–36.0%) in those with ACLF grade 3 (p

Abstract

Conflict of interest: No Introduction and Objectives: The 2024 WHO guidelines for chronic hepatitis B (CHB) aim to expand and simplify treatment eligibility, but these criteria have not been assessed. We aimed to estimate treatment eligibility and uptake according to country-specific guidelines and evaluate potential treatment expansion based on the WHO guidelines. Patients / Materials and Methods: This cross-sectional study included consecutive treatment-naïve CHB patients from Argentina, Brazil, Chile, and Uruguay who were referred for the first time to hepatology evaluation between January 2010 and June 2024. Treatment candidacy was evaluated according to both country-specific and WHO guidelines. We then estimated the difference in treatment candidacy between these two approaches. Results and Discussion: A total of 719 patients with CHB had complete data available to evaluate treatment candidacy according to both guidelines. Of these patients, 67% were male with a median age of 52 years (IQR 38-62), and 8.1% presented with liver decompensation. Among patients, 64% were HBeAg-negative, median HBV DNA level was 43,000 IU/ml (IQR 633-110,000,000 IU/ml), median ALT was 41 U/L (IQR 23-99 U/L), and 47% had an APRI >0.5. According to country-specific guidelines, 57% (95% CI: 53-60) met criteria for treatment. Antiviral treatment was initiated in 84% of eligible patients, primarily with entecavir (63%) and tenofovir (32%). Compared to country-specific guidelines, the proportion of patients meeting treatment criteria under the WHO guidelines increased to 67% (95% CI: 63.8-70.6), resulting in a 10% (95% CI: 8-13) increase in treatment candidacy (table). Treatment expansion was higher in women (15%; 95% CI: 10-20) than in men (8%; 95% CI: 5-11). Conclusions: According to WHO guidelines, a considerable proportion of CHB patients who do not meet country-specific criteria are eligible for antiviral therapy. Notably, treatment expansion is higher in women. Implementing WHO criteria can enhance treatment rates and advance efforts toward CHB elimination.

Abstract

Background & Aims: Model for End-Stage Liver Disease (MELD) score better predicts mortality in alcohol-associated hepatitis (AH) but could underestimate severity in women and malnourished patients. Using a global cohort, we assessed the ability of the MELD 3.0 score to predict short-term mortality in AH. Methods: This was a retrospective cohort study of patients admitted to hospital with AH from 2009 to 2019. The main outcome was all-cause 30-day mortality. We compared the AUC using DeLong's method and also performed a time-dependent AUC with competing risks analysis. Results: A total of 2,124 patients were included from 28 centres from 10 countries on three continents (median age 47.2 ± 11.2 years, 29.9% women, 71.3% with underlying cirrhosis). The median MELD 3.0 score at admission was 25 (20–33), with an estimated survival of 73.7% at 30 days. The MELD 3.0 score had a better performance in predicting 30-day mortality (AUC:0.761, 95%CI:0.732–0.791) compared with MELD sodium (MELD-Na; AUC: 0.744, 95% CI: 0.713–0.775; p = 0.042) and Maddrey’s discriminant function (mDF) (AUC: 0.724, 95% CI: 0.691–0.757; p = 0.013). However, MELD 3.0 did not perform better than traditional MELD (AUC: 0.753, 95% CI: 0.723–0.783; p = 0.300) and Age-Bilirubin-International Normalised Ratio-Creatinine (ABIC) (AUC:0.757, 95% CI: 0.727–0.788; p = 0.765). These results were consistent in competing-risk analysis, where MELD 3.0 (AUC: 0.757, 95% CI: 0.724–0.790) predicted better 30-day mortality compared with MELD-Na (AUC: 0.739, 95% CI: 0.708–0.770; p = 0.028) and mDF (AUC:0.717, 95% CI: 0.687–0.748; p = 0.042). The MELD 3.0 score was significantly better in predicting renal replacement therapy requirements during admission compared with the other scores (AUC: 0.844, 95% CI: 0.805–0.883). Conclusions: MELD 3.0 demonstrated better performance compared with MELD-Na and mDF in predicting 30-day and 90-day mortality, and was the best predictor of renal replacement therapy requirements during admission for AH. However, further prospective studies are needed to validate its extensive use in AH. Impact and implications: Severe AH has high short-term mortality. The establishment of treatments and liver transplantation depends on mortality prediction. We evaluated the performance of the new MELD 3.0 score to predict short-term mortality in AH in a large global cohort. MELD 3.0 performed better in predicting 30- and 90-day mortality compared with MELD-Na and mDF, but was similar to MELD and ABIC scores. MELD 3.0 was the best predictor of renal replacement therapy requirements. Thus, further prospective studies are needed to support the wide use of MELD 3.0 in AH.

Abstract

Introduction and Objectives: there is insufficient data regarding bacterial infections in patients with cirrhosis to support recommendations for empiric antibiotic treatments, particularly in Latin America. This study aimed to evaluate bacterial infection's clinical impact and microbiological characteristics, intending to serve as a platform to revise current practices. Materials and Methods: multicenter prospective cohort study of patients with cirrhosis and bacterial infections from Argentina and Uruguay. Patient and infection-related information were collected, focusing on microbiology, antibiotic susceptibility patterns, and outcomes. Results: 472 patients were included. Spontaneous bacterial infections and urinary tract infections (UTIs) were registered in 187 (39.6%) and 116 (24.6%) patients, respectively, representing the most common infections. Of the 256 culture-positive infections, 103 (40.2%) were caused by multidrug-resistant organisms (reaching 50% for UTI), and 181 (70.7%) received adequate initial antibiotic treatment. The coverage of cefepime and ceftriaxone was over 70% for the empirical treatment of community-acquired spontaneous infections, but ceftazidime´s coverage was only 40%. For all UTI cases and for healthcare-associated or nosocomial spontaneous bacterial infections, the lower-spectrum antibiotics that covered at least 70% of the isolations were imipenem and meropenem. During hospitalization, a second bacterial infection was diagnosed in 9.8% of patients, 23.9% required at least one organ support, and 19.5% died. Conclusions: short-term mortality of bacterial infections in patients with cirrhosis is very high, and a high percentage were caused by multidrug-resistant organisms, particularly in UTIs. The information provided might serve to adapt recommendations, particularly related to empirical antibiotic treatment in Argentina and Uruguay. The study was registered in Clinical Trials (NCT03919032).

Abstract

Introduction and Objectives: Although most cases of HCC occur in patients with advanced liver disease and there are effective screening methods, health policies aimed at preventing and detecting HCC are not often on the agenda of government initiatives and policies. This study aimed to explore HCC-related population-wide public health policies, treatment availability, epidemiological surveillance, and awareness campaigns in the Americas. Materials and Methods: We conducted a 43-item survey about HCC among experts from 12 countries. Questions were classified into four categories: policies and civil society (18 questions), clinical guidelines (5 questions), epidemiology (7 questions), and care management (13 questions). The survey was administered using an electronic form in May 2022. Data was collected in a spreadsheet, revised by two independent reviewers, and contrasted with governmental institutions. Results: We obtained 22 responses from 15 out of the 18 countries targeted. A total of 7 (47%) countries had a written national cancer strategy or action plan. Only 4 (27%) countries had a specific written national HCC strategy or action plan, including Argentina, Brazil, Mexico, and the United States. These same four countries also had national clinical guidelines on HCC. HCC is managed by various providers, including Hepatologists (80%), Oncologists (80%), Gastroenterologists (60%), Surgeons (47%), and Palliative medicine (20%). There were important differences in the availability of treatments among countries in the Americas (Figure). Of note, 60% of countries had liver transplantation available for HCC, but only 67% of them had this therapy outside the capital city. Nine (60%) countries had a national disease registry that included HCC. However, only Brazil (7%) had governmental funded awareness campaigns on HCC prevention or screening. Conclusions: Implementation of public health policies on HCC is scarce in the Americas. Important differences in treatments were observed across countries, especially in curative therapies. Our results strongly encourage developing public health policies on HCC in the Americas.

Abstract

Introduction and Objectives: Alcohol-associated hepatitis (AH) is a severe entity associated with high mortality. Corticosteroids might be used in cases with severe disease and several dynamic models can predict mortality and response to corticosteroids in AH patients. However, there is no consensus on the best of them. This study aimed to evaluate dynamic models to predict response to corticosteroid treatment based on short-term mortality in patients with severe AH based on a worldwide cohort. Materials and Methods: A retrospective cohort study of patients with severe AH (between 2009 – 2019). We included patients who received corticosteroid treatment and calculated the Lille model of day 4 (Lille-4), day 7 (Lille-7) (cut-off value ≥0.45), and the Trajectory of Serum Bilirubin (TSB)(cut-off value ≥0.8 of the ratio between bilirubin at admission and day 7) to predict mortality. We estimated up to 30-day survival using Kaplan-Meier curves, and we performed multivariable analyzes using Cox regression. Specifically, we constructed two models to compare Lille-4 vs. TSB and Lille-7 vs. TSB, adjusting by well-known clinical variables associated with higher mortality in AH (age, sex, and creatinine at admission). Results: 1,066 patients were included (30 centers, 10 countries), age 47.7 ± 10.9 years, 30% women. The MELD score on admission was 25 [21-30]. Responders were considered by Lille-4 49.1%, Lille-7 46.6%, and TSB 55.4%. In the first Cox regression, we observed that Lille-4 and TSB predicted 30-day mortality (HR 3.0, 95%CI: 1.7-5.1; p

Abstract

Introduction and Objectives: Severe alcohol-associated hepatitis (AH) is an entity with high morbidity and mortality; however, data in Latin America is limited. We aimed to characterize patients hospitalized for AH in a multinational cohort in Latin America. Materials and Methods: Multicenter prospective cohort study. We included patients admitted with severe AH between 2015-2022. Sociodemographic and clinical information was recorded. The analysis included survival analysis using Kaplan-Meier curves. This study was approved by the institutional ethics committee. Results: 470 patients from 24 centers (8 countries: Mexico, Chile, Argentina, Brazil, Peru, Bolivia, Colombia, and Ecuador) were included. Age 49.8 ± 10.6 years, 85.6% of men and 45% had a previous diagnosis of cirrhosis. Median MELD at admission was 26.9 [22-32] points. 26.5% met SIRS criteria and 34.3% had an acute kidney injury (AKI) on admission. Only 36.8% of patients were treated with corticosteroids. Survival at 30 days was 75.0% (95%CI: 70.1-79.3%) and 62.8% (95%CI: 57.1-68.0%) at 90 days. A total of 191 (45.8%) patients presented infections, 31.4% at admission and 24.9% during hospitalization. The most frequent locations of community-acquired infections were respiratory (33.5%), urinary (32.1%), spontaneous bacterial peritonitis (14.9%), and skin (10.5%), while the most frequent pathogens were Escherichia coli (40%), Klebsiella pneumoniae (12%), and Enterococcus (6%). The presence of infection at admission was associated with a decreased survival at 90-days (66.9% versus 48.1%, p=0.0002). AKI at admission was also associated with decreased survival at 90-days (86.8% versus 51.3%, p

Abstract

Introduction and Objectives: Selecting an empiric antibiotic treatment in patients with cirrhosis and spontaneous bacterial infections is challenging. It is of paramount importance to have local epidemiological data to maximize pathogen coverage while minimizing the unnecessary use of broad-spectrum antibiotics. This study aimed to describe the patterns of antibiotic resistance of spontaneous bacterial infections according to the site of acquisition. Materials and Methods: Analysis of the multicenter prospective cohort study of cirrhotic patients with bacterial infections in Argentina and Uruguay (NCT03919032). Only culture-positive spontaneous infections were included in this study: spontaneous bacterial peritonitis (SBP), spontaneous bacterial empyema (SBE), and spontaneous bacteremia (SB). We estimated the proportion of infections that were sensitive to various antibiotics according to where the infection was acquired: community-acquired (CA), healthcare-associated (HCA), or nosocomial (NOS). Approximately 80% coverage is advisable for empiric treatments in stable patients and 90% for critically-ill patients. Results: The main cohort included 472 patients, of whom 97 presented culture-positive spontaneous infections and were included: with 57 (59%) SBP, 34 (35%) SB, and 4 (6%) SBE. Regarding the site of acquisition, 43% were CA, 36% NOS, and 21% HCA. Gram-positive and negative bacteria were found in 53% and 47% of the infections. The most frequent isolations were Streptococcus spp (26%), E coli (20), K pneumonia (15%), S Aureus (10%), E. faecium (6%) and E. faecalis (4%). Multidrug-resistant organisms (MDROs) were isolated in 35% of the patients. As shown in the table, cefepime and ceftriaxone offer the most rational coverage for CA and HCA infections, and imipenem or meropenem for NOS infections. However, in critically-ill patients, broader-spectrum antibiotics are needed to achieve a coverage closer to 90% (table). Conclusions: We present, for the first time in our region, evidence-based recommendations for the empirical treatment of spontaneous bacterial infections. Prior colonization and/or infections by MDROs might refine even more the antibiotic selection and should be explored.

Abstract

Introduction and objectives: After hepatitis A (HAV) mandatory immunization in 2005 in Argentina, the incidence of HAV declined drastically. However, several new autochthonous cases of HAV have been reported since 2017. We aimed to evaluate the clinical and epidemiological characteristics and possible transmission routes of affected patients. Patients or Materials and methods: We performed a cross-sectional study of patients residing in Argentina with acute hepatitis A between 30.06.2017 and 31.12.2018. Results: 66 cases of HAV were registered. Fifty-six patients (86%) were males, with a mean age of 34 ± 12 years old. The most likely routes of transmission were sexual intercourse of men with men, reported by 31 patients. Additionally, 23% and 26% of patients tested positive for HIV and syphilis, respectively. In total, 35% of patients required hospitalization. When assessing outcomes, 79% had a mild presentation and 21% had a severe/fulminant presentation: one patient underwent liver transplantation, and one patient died. Conclusions: Our study describes that during the study period, HAV infection affected predominantly young adults, particularly men who have sex with men. An elevated proportion of them was diagnosed with a concomitant sexually transmitted disease, and several patients had a severe presentation of the disease.

Abstract

Non-alcoholic fatty liver disease (NAFLD) currently represents an epidemic worldwide. NAFLD is the most frequently diagnosed chronic liver disease, affecting 20–30% of the general population. Furthermore, its prevalence is predicted to increase exponentially in the next decades, concomitantly with the global epidemic of obesity, type 2 diabetes mellitus (T2DM), and sedentary lifestyle. NAFLD is a clinical syndrome that encompasses a wide spectrum of associated diseases and hepatic complications such as hepatocellular carcinoma (HCC). Moreover, this disease is believed to become the main indication for liver transplantation in the near future. Since NAFLD management represents a growing challenge for primary care physicians, the Asociación Latinoamericana para el Estudio del Hígado (ALEH) has decided to organize this Practice Guidance for the Diagnosis and Treatment of Non-Alcoholic Fatty Liver Disease, written by Latin-American specialists in different clinical areas, and destined to general practitioners, internal medicine specialists, endocrinologists, diabetologists, gastroenterologists, and hepatologists. The main purpose of this document is to improve patient care and awareness of NAFLD. The information provided in this guidance may also be useful in assisting stakeholders in the decision-making process related to NAFLD. Since new evidence is constantly emerging on different aspects of the disease, updates to this guideline will be required in future.

Abstract

The A.A.E.E.H has developed this guideline for the best care of patients with hepatocellular carcinoma (HCC) from Argentina. It was done from May 2018 to March 2020. Specific clinical research questions were systematically searched. The quality of evidence and level of recommendations were organized according to GRADE. HCC surveillance is strongly recommended with abdominal ultrasound (US) every six months in the population at risk for HCC (cirrhosis, hepatitis B or hepatitis C); it is suggested to add alpha-feto protein (AFP) levels in case of inexeperienced sonographers. Imaging diagnosis in patients at risk for HCC has high specificity and tumor biopsy is not mandatory. The Barcelona Clinic Liver Cancer algorithm is strongly recommended for HCC staging and treatment-decision processes. Liver resection is strongly recommended for patients without portal hypertension and preserved liver function. Composite models are suggested for liver transplant selection criteria. Therapies for HCC with robust clinical evidence include transarterial chemoembolization (TACE) and first to second line systemic treatment options (sorafenib, lenvatinib, regorafenib, cabozantinib and ramucirumab). Immunotherapy with nivolumab and pembrolizumab has failed to show statistical benefit but the novel combination of atezolizumab plus bevacizumab has recently shown survival benefit over sorafenib in frontline.

Abstract

The Child-Turcotte-Pugh (CTP) and the MELD (Model for End-Stage Liver Disease) scores were designed to predict the outcome of decompressive therapy for portal hypertension. They were prospectively validated to predict mortality risk in patients with a wide spectrum of liver disease etiology and severity. Unlike the CTP score, the MELD score was derived from prospectively gathered data. Its calculation was based on serum bilirubin, serum creatinine, international normalized ratio (INR) and etiology of liver disease. Instituting a continuous disease severity score that de-emphasizes waiting time resulted in better categorization of waiting patients and enhanced transparency. The US instituted the MELD system in 2002 and soon thereafter, MELD-based liver allocation was adopted throughout the world including Latin America. The most significant impact of MELD-based policies has been the reduction of waiting-list mortality. In the years after implementation of the MELD system, several options have been proposed to improve the MELD score's accuracy. Adding serum sodium (MELD-Na) increased the accuracy of the score in predicting waiting list mortality, thus completing the original MELD score as a prognostic model in liver allocation. On the 20th anniversary of the creation of MELD score we present a brief account of its development, its use to stratify patients on the waiting list for liver transplantation as well as its adoption as liver allocation system .

Abstract

Introduction and objectives: Failures at any step in the hepatocellular carcinoma (HCC) surveillance process can result in HCC diagnostic delays and associated worse prognosis. We aimed to estimate the prevalence of surveillance failure and its associated risk factors in patients with HCC in Argentina, considering three steps: 1) recognition of at-risk patients, 2) implementation of HCC surveillance, 3) success of HCC surveillance. Methods: We performed a multi-center cross-sectional study of patients at-risk for HCC in Argentina seen between10.01.2018 and 10.30.2019. Multivariable logistic regression analysis was used to identify correlates of surveillance failure. Results: Of 301 included patients, the majority were male (74.8%) with a mean age of 64 years old. At the time of HCC diagnosis, 75 (25%) patients were unaware of their diagnosis of chronic liver disease, and only 130 (43%) patients were under HCC surveillance. Receipt of HCC surveillance was significantly associated with follow-up by a hepatologist. Of 119 patients with complete surveillance, surveillance failure occurred in 30 (25%) patients. Surveillance failure was significantly associated with alpha fetoprotein ≥20 ng/mL (OR 4.0, CI 95% 1.43−11.55). Conclusions: HCC surveillance failure was frequent in all the evaluated steps. These data should help guide strategies to improve the implementation and results of HCC surveillance in our country.

Abstract

Non-alcoholic fatty liver disease (NAFLD) is reaching epidemic proportions worldwide. Collectively, Latin American countries have some of the highest obesity rates in the world and the fastest-growing prevalence of type 2 diabetes mellitus (T2DM). Since obesity and T2DM are intrinsically linked with NAFLD, epidemiological projections are worrisome. In addition to this adverse epidemiological setting, the region of Latin America faces unique challenges and obstacles to addressing the growing burden of NAFLD. In this article, on the occasion of the International NASH Day on June 10, 2021, we describe the main challenges and opportunities to improve care of people living with NAFLD in Latin America. Among the major challenges to be tackled are: lack of disease awareness, limited educational opportunities for healthcare personnel and general public, health system fragmentation, and lack of effective strategies for the prevention and effective treatment of NAFLD and common comorbidities, namely obesity and T2DM. Wide dissemination of current concepts on NAFLD, and extensive collaboration between scientific societies, governments, non-governmental organizations, pharmaceutical industry, and other stakeholders is urgently needed to advance the NAFLD public health policies agenda that allows us to address this disease with a whole of society approach.

Abstract

Background: Antibiotic de-escalation is considered a safe strategy that reduces costs and the risk of multi-drug resistant infections. However, its prevalence and associated factors in real-life practice were not reported in patients with cirrhosis in Latin-America. Aims: To estimate the prevalence of antibiotic de-escalation in patients with cirrhosis in real life-practice, and to explore its associated factors. Methods: We performed an analysis of the multicenter prospective cohort study of cirrhotic patients with bacterial infections throughout Argentina and Uruguay (clinicatrials.gov NCT03919032). Patients who died in the first 72 hs from the diagnosis of the infection were excluded. In accordance with guidelines, de-escalation was defined as changing the initially antimicrobials to a narrower spectrum regimen, or suspending one or more of the empirical antibiotics, according to culture results or to other clinical reasons, either in patients with culture-positive or culture-negative bacterial infections. We used inverse probability weighting (IPW) of having a culture-positive infection to estimate its causal effect on de-escalation. Results: We included 450 patients. Most frequent infections were SBP (30.4%), and urinary tract infection (12.9%). Overall, 243 (54%) infections were culture-positive, and 207 (46%) culture-negative. De-escalation was reported in 85 patients (18.9%: 95% CI 15%-22%) at a mean of 3.3 ± 2.4 days from treatment initiation and was more frequent in culture-positive than culture-negative infections (28.4% vs 7.7%, p< 0.001). The table shows the crude analyses of variables associated with de-escalation. Culture-positive infection was strongly and independently associated with de-escalation (ORIPW 6.08; 95% CI: 2.90-12.70; p < 0.001). Conclusions: Antibiotic de-escalation was reported in one-fifth of in-patients with cirrhosis. Given that having a culture-positive infection had a strong effect on de-escalation, efforts should be made to increase the likelihood of obtaining adequate culture samples in a timely manner.

Abstract

Background: Predicting short-term mortality in patients with cirrhosis and bacterial infections is challenging. Aims: To compare the performance of various scores in predicting in-hospital mortality in this population. Methods: We performed an analysis of the multicenter prospective cohort study of patients with cirrhosis with bacterial infections throughout Argentina and Uruguay (clinicatrials.gov.NCT03919032). Patients were classified according to the CLIF criteria as having ACLF or mere acute decompensation (AD). We evaluated the performance of scores of liver disease and infection severity in predicting in-hospital mortality. MELD, MELD-Na, and Quick SOFA (qSOFA) were computed in all patients. CLIF-AD was only computed in patients without ACLF, and CLIF-ACLF only in patients with ACLF. We plotted ROC curves and estimated their area under the curve (AUROC). Results: We included 472 patients: 66% male, mean age 57 ± 12 years. Most frequent infections: SBP (30%) and urinary tract infection (25%). Overall, 332 (70%) patients had acute decompensation, and 140 (30%) ACLF. In-hospital mortality rate was 19%: 41% in patients with ACLF vs 10% in patients with AD (p

Abstract

Hepatocellular carcinoma (HCC) is one of the main cancer-related causes of death worldwide. Thus, there is a constant search for improvement in screening, diagnosis, and treatment strategies to improve the prognosis of this malignancy. The identification of useful biomarkers for surveillance and early HCC diagnosis is still deficient, with available serum biomarkers showing low sensitivity and heterogeneous specificity despite different cut-off points, even when assessed longitudinally, or with a combination of serum biomarkers. In contrast, HCC biomarkers used for prognostic (when associated with clinical outcomes) or predictive purposes (when associated with treatment response) may have an increased clinical role in the near future. Furthermore, some serum biomarkers are already implicated as a treatment selection tool, whether to provide access to certain therapies or to assess clinical benefit after treatment. In the present review we will discuss the clinical utility and foreseen future of HCC biomarkers implicated in surveillance, diagnosis, prognosis, and post-treatment assessment.

Abstract

Killer cell immunoglobulin-like receptor (KIR) genes are known to play a role in the acute phase of hepatitis C virus (HCV) infection. The present study investigated their roles in chronic HCV (CHCV) infection by analyzing the phenotypes and function of natural killer (NK) and T cells that express KIRs. T cells from CHCV patients showed a more differentiated phenotype, and NK cells exhibited an activated profile. These observations are consistent with the increased expression of the degranulation marker CD107a observed after PMA stimulation. We explored the correlations between the expression of KIR genes and lectin type-C receptors with clinical factors that predict progression to fibrosis and cirrhosis. The expression levels of KIR2DS3 and the functional alleles of KIR2DS4-FL were increased in patients with intermediate and high viral loads. Homozygous KIR2DS4 was also associated with the presence of cirrhosis. In the group of individuals with a shorter infection time who developed cirrhosis, we detected decreased expression of KIR3DL1 in CD56dim NK cells in the presence of its ligand. Similarly, in the group of patients with late CHCV infections complicated with cirrhosis, we detected lower expression of the strong inhibitory receptor NKG2A in CD56bright NK cells. We also detected an increase in NKG2C expression in CD56dim NK cells in CHCV patients who displayed high necroinflammatory activity. Decreased KIR3DL2 expression in CD56dim and CD56bright NK cells was associated with a high body mass index, and KIR3DL2 expression may be one factor associated with the more rapid progression of CHCV to fibrosis in patients.

Abstract

BACKGROUND There is limited information on the effects of statins on the outcomes of liver transplantation (LT), regarding either their use by LT recipients or donors. AIM To analyse the association between statin exposure and recipient and graft survival. METHODS We included adult LT recipients with deceased donors in a nationwide prospective database study. Using a multistate modelling approach, we examined the effect of statins on the transition hazard between LT, biliary and vascular complications and death, allowing for recurring events. The observation time was 3 years. RESULTS We included 998 (696 male, 70%, mean age 54.46 ± 11.14 years) LT recipients. 14% of donors and 19% of recipients were exposed to statins during the study period. During follow-up, 141 patients died; there were 40 re-LT and 363 complications, with 66 patients having two or more complications. Treatment with statins in the recipient was modelled as a concurrent covariate and associated with lower mortality after LT (HR = 0.35; 95% CI 0.12-0.98; p = 0.047), as well as a significant reduction of re-LT (p = 0.004). However, it was not associated with lower incidence of complications (HR = 1.25; 95% CI = 0.85-1.83; p = 0.266). Moreover, in patients developing complications, statin use was significantly associated with decreased mortality (HR = 0.10; 95% CI = 0.01-0.81; p = 0.030), and reduced recurrence of complications (HR = 0.43; 95% CI = 0.20-0.93; p = 0.032). CONCLUSIONS Statin use by LT recipients may confer a survival advantage. Statin administration should be encouraged in LT recipients when clinically indicated.

Abstract

The principal limitations of the terms NAFLD and NASH are the reliance on exclusionary confounder terms and the use of potentially stigmatising language. This study set out to determine if content experts and patient advocates were in favour of a change in nomenclature and/or definition. A modified Delphi process was led by three large pan-national liver associations. The consensus was defined a priori as a supermajority (67%) vote. An independent committee of experts external to the nomenclature process made the final recommendation on the acronym and its diagnostic criteria. A total of 236 panellists from 56 countries participated in 4 online surveys and 2 hybrid meetings. Response rates across the 4 survey rounds were 87%, 83%, 83%, and 78%, respectively. Seventy-four percent of respondents felt that the current nomenclature was sufficiently flawed to consider a name change. The terms “nonalcoholic” and “fatty” were felt to be stigmatising by 61% and 66% of respondents, respectively. Steatotic liver disease was chosen as an overarching term to encompass the various aetiologies of steatosis. The term steatohepatitis was felt to be an important pathophysiological concept that should be retained. The name chosen to replace NAFLD was metabolic dysfunction–associated steatotic liver disease (MASLD). There was consensus to change the definition to include the presence of at least 1 of 5 cardiometabolic risk factors. Those with no metabolic parameters and no known cause were deemed to have cryptogenic steatotic liver disease. A new category, outside pure metabolic dysfunction–associated steatotic liver disease, termed metabolic and alcohol related/associated liver disease (MetALD), was selected to describe those with metabolic dysfunction–associated steatotic liver disease, who consume greater amounts of alcohol per week (140–350 g/wk and 210–420 g/wk for females and males, respectively). The new nomenclature and diagnostic criteria are widely supported and non-stigmati

Abstract

Resumen: Introducción y objetivos: La estadificación de la fibrosis en pacientes con enfermedad por hígado graso no alcohólico (EHGNA) se realiza aplicando distintos algoritmos. Sin embargo, hay pocos reportes de cómo se utilizan en la vida real. Nuestro objetivo fue estimar la proporción de pacientes con EHGNA que teniendo riesgo indeterminado o alto de fibrosis según scores no-invasivos se someten a estudios adicionales de estadificación. Materiales y métodos: Estudio de corte transversal multicéntrico de pacientes con EHGNA evaluados por hepatólogos del 1 de junio del 2018 al 31 de julio del 2018. Se calcularon FIB-4 y NAFLD fibrosis score en todos los pacientes y se consideró que, si al menos uno de los scores sugería riesgo indeterminado o alto de fibrosis, el paciente debería haberse sometido a estudios adicionales de estadificación. Resultados: Se incluyeron 238 pacientes. La mediana de tiempo entre el diagnóstico de EHGNA y la inclusión en el estudio fue de 12.2 (IQR 3.0-36.5) meses. En total, 128 (54%) pacientes tuvieron al menos una evaluación con score no-invasivo que sugería riesgo indeterminado o alto de fibrosis. Sin embargo, solamente 72 (56%) se realizaron estudios para confirmar el grado de fibrosis (elastografía, biopsia, etc.). Las principales barreras encontradas por los médicos para aplicar los algoritmos de estadificación fueron relacionadas a cobertura de salud y a costos. Conclusiones: Un alto porcentaje de pacientes con EHGNA tiene riesgo indeterminado o alto de fibrosis, de acuerdo con los resultados obtenidos con scores no invasivos. Sin embargo, solamente la mitad se realizó estudios adicionales, evidenciando una baja adherencia a las recomendaciones actuales. Abstract: Introduction and aims: Fibrosis staging in patients with nonalcoholic fatty liver disease (NAFLD) is carried out through the application of stepwise algorithms but there is little real-world data on their use. Our aim was to calculate the number of patients with NAFLD and indeterminate or high risk for fibrosis, assessed through noninvasive scores, that consequently underwent further staging evaluation. Materials and methods: A cross-sectional multicenter cohort study was conducted on patients with NAFLD evaluated by hepatologists within the time frame of June 1 and July 31, 2018. The FIB-4 and NAFLD fibrosis scores were calculated in all the patients, and if at least one of the scores suggested indeterminate or high risk for fibrosis, we believed the patient should have undergone additional fibrosis staging assessment. Results: The study included 238 patients. The median time interval from NAFLD diagnosis and inclusion in the analysis was 12.2 months (IQR 3.0-36.5). A total of 128 (54%) patients had at least one noninvasive score that suggested indeterminate or high risk for fibrosis but studies to confirm the fibrosis grade (elastography, biopsy, etc.) were performed on only 72 (56%). The main barriers encountered by the physicians for applying the staging algorithms were related to health insurance coverage and imaging study costs. Conclusions: A high percentage of patients with NAFLD were at indeterminate or high risk for fibrosis, according to noninvasive scores, but additional studies were carried out on only half of them, showing low adherence to current recommendations.

Abstract

The Latin American Association for the Study of the Liver (Asociación Latinoamericana para el Estudio del Hígado; ALEH) represents liver professionals in Latin America with the mission of promoting liver health and quality patient care by advancing the science and practice of hepatology and contributing to the development of a regional health policy framework. Fatty liver disease associated with metabolic dysfunction is of specific concern in the ALEH region, where its prevalence is one of the highest globally, second only to the Middle East. A recent consensus from an international panel recommended a new definition of fatty liver disease associated with metabolic dysfunction, including a shift in name from non-alcoholic fatty liver disease (NAFLD) to metabolic-associated fatty liver disease (MAFLD), and adoption of a set of positive criteria to diagnose the disease, independent of alcohol intake or other liver diseases. Given, the importance of this proposal, ALEH invited leading members of regional nations to come to a consensus on it from a local perspective. We reached a consensus to endorse the proposal that the disease should be renamed as MAFLD and that the disease should be diagnosed by the proposed simple and easily applicable criteria. We expect that this change in nosology will result in improvements in disease awareness and in advances in scientific, economic, public health, political, and regulatory aspects of the disease.

Abstract

Introduction and objectives After hepatitis A (HAV) mandatory immunization in 2005 in Argentina, the incidence of HAV declined drastically. However, several new autochthonous cases of HAV have been reported since 2017. We aimed to evaluate the clinical and epidemiological characteristics and possible transmission routes of affected patients. Patients or Materials and methods We performed a cross-sectional study of patients residing in Argentina with acute hepatitis A between 30.06.2017 and 31.12.2018. Results 66 cases of HAV were registered. Fifty-six patients (86%) were males, with a mean age of 34 ± 12 years old. The most likely routes of transmission were sexual intercourse of men with men, reported by 31 patients. Additionally, 23% and 26% of patients tested positive for HIV and syphilis, respectively. In total, 35% of patients required hospitalization. When assessing outcomes, 79% had a mild presentation and 21% had a severe/fulminant presentation: one patient underwent liver transplantation, and one patient died. Conclusions Our study describes that during the study period, HAV infection affected predominantly young adults, particularly men who have sex with men. An elevated proportion of them was diagnosed with a concomitant sexually transmitted disease, and several patients had a severe presentation of the disease.

Abstract

The A.A.E.E.H has developed this guideline for the best care of patients with hepatocellular carcinoma (HCC) from Argentina. It was done from May 2018 to March 2020. Specific clinical research questions were systematically searched. The quality of evidence and level of recommendations were organized according to GRADE. HCC surveillance is strongly recommended with abdominal ultrasound (US) every six months in the population at risk for HCC (cirrhosis, hepatitis B or hepatitis C); it is suggested to add alpha-feto protein (AFP) levels in case of inexeperienced sonographers. Imaging diagnosis in patients at risk for HCC has high specificity and tumor biopsy is not mandatory. The Barcelona Clinic Liver Cancer algorithm is strongly recommended for HCC staging and treatment-decision processes. Liver resection is strongly recommended for patients without portal hypertension and preserved liver function. Composite models are suggested for liver transplant selection criteria. Therapies for HCC with robust clinical evidence include transarterial chemoembolization (TACE) and first to second line systemic treatment options (sorafenib, lenvatinib, regorafenib, cabozantinib and ramucirumab). Immunotherapy with nivolumab and pembrolizumab has failed to show statistical benefit but the novel combination of atezolizumab plus bevacizumab has recently shown survival benefit over sorafenib in frontline.

Abstract

Nonalcoholic fatty liver disease (NAFLD) is the most frequent chronic liver disease worldwide, with an estimated global prevalence of approximately 25%, that is much higher in patients with overweight, obesity and type 2 diabetes. NAFLD is considered as the hepatic manifestation of metabolic syndrome. It has a wide spectrum, from simple steatosis to steatohepatitis, fibrosis, cirrhosis and its complications, such as hepatocellular carcinoma. Most of the affected patients will not evolve to advanced fibrosis or cirrhosis. Despite this, it has been described that the hepatic disease is the third cause of death among patients with nonalcoholic fatty liver, after cardiovascular and malignant diseases. Among the huge number of patients affected, the main challenge is to identify those who are at risk of developing cirrhosis or its complications and to recognize the diagnostic and treatment options. In this Guideline, endorsed by the Argentine Association for the Study of Liver Diseases, the definitions, epidemiological aspects, natural history and a practical approach to possible algorithms to estimate the severity of liver disease in the individual patient are reviewed; in addition to analyzing advances in treatment and proposing recommendations for follow-up. It is important to note that no data on the incidence or prevalence of the disease have been published in the general population of Argentina, and it is encouraged to carry them out.

Abstract

Non-alcoholic fatty liver disease (NAFLD) affects 20-25% of the general population and is associated with morbidity, increased mortality, and elevated health-care costs. Most NAFLD risk factors are modifiable and, therefore, potentially amenable to being reduced by public health policies. To date, there is no information about NAFLD-related public health policies in the Americas. In this study, we analysed data from 17 American countries and found that none have established national public health policies to decrease NAFLD-related burden. There is notable heterogeneity in the existence of public health policies to prevent NAFLD-related conditions. The most common public health policies were related to diabetes (15 [88%] countries), hypertension (14 [82%] countries), cardiovascular diseases (14 [82%] countries), obesity (nine [53%] countries), and dyslipidaemia (six [35%] of countries). Only seven (41%) countries had a registry of the burden of NAFLD, and efforts to raise awareness in the Americas were scarce. The implementation of public health policies are urgently needed in the Americas to decrease the burden of NAFLD.

Abstract

MELD exceptions are designed to equipoise liver transplant waiting list survival. We aimed to analyze the impact of the MELD Upgrade rule and all other MELD exceptions on the liver transplant waiting list outcomes during 2012-2017 in Switzerland.We conducted a nationwide cohort study including all adult patients registered on the Swiss liver transplant waiting list between 2012 and 2017. Waiting list mortality and access to transplantation were analyzed, considering MELD exceptions as time-dependent covariates.730 patients were included. Patients with MELD Upgrade exceptions had a higher risk of dying while on the waiting list (OR 2.13; CI 95% 1.30-3.47) and also an increased likelihood of receiving a liver transplantation, when compared to patients without MELD exceptions. Patients with any type of MELD exceptions were more likely to be transplanted when compared to patients without MELD exceptions. The proportion of patients with MELD exceptions increased from 2012 to 2017 (44% vs 88%). Allocation MELD at the time of transplantation showed an annual increase (23 ± 8 points vs 32 ± 5 points, p 0.001).Only patients with MELD Upgrade exceptions had the expected combination of higher waiting list mortality and quicker access to liver transplantation.

Abstract

Spontaneous bacterial peritonitis is the most frequent bacterial infection in patients with cirrhosis. The reported incidence varies between 7% and 30% in hospitalized patients with cirrhosis and ascites, representing one of their main complications. Outcomes in patients with spontaneous bacterial peritonitis are poor since acute kidney injury, acute-on-chronic liver failure, and death occur in as much as 54%, 60%, and 40% of the patients, respectively, at midterm. Early antibiotic treatment of spontaneous bacterial peritonitis is crucial. However, the landscape of microbiological resistance is continuously changing, with an increasing spread of multidrug-resistant organisms that make its current management more challenging. Thus, the selection of the empirical antibiotic treatment should be guided by the severity and location where the infection was acquired, the risk factors for multidrug-resistant organisms, and the available information on the local expected bacteriology. The use of albumin as a complementary therapy for selected high-risk patients with spontaneous bacterial peritonitis is recommended in addition to antibiotics. Even though antibiotic prophylaxis has proven to be effective to prevent spontaneous bacterial peritonitis, a careful selection of high-risk candidates is crucial to avoid antibiotic overuse. In this article we review the pathogenesis, risk factors, and prognosis of spontaneous bacterial peritonitis, as well as the current evidence regarding its treatment and prophylaxis.

Abstract

The Child-Turcotte-Pugh (CTP) and the MELD (Model for End-Stage Liver Disease) scores were designed to predict the outcome of decompressive therapy for portal hypertension. They were prospectively validated to predict mortality risk in patients with a wide spectrum of liver disease etiology and severity. Unlike the CTP score, the MELD score was derived from prospectively gathered data. Its calculation was based on serum bilirubin, serum creatinine, international normalized ratio (INR) and etiology of liver disease. Instituting a continuous disease severity score that de-emphasizes waiting time resulted in better categorization of waiting patients and enhanced transparency. The US instituted the MELD system in 2002 and soon thereafter, MELD-based liver allocation was adopted throughout the world including Latin America. The most significant impact of MELD-based policies has been the reduction of waiting-list mortality. In the years after implementation of the MELD system, several options have been proposed to improve the MELD score's accuracy. Adding serum sodium (MELD-Na) increased the accuracy of the score in predicting waiting list mortality, thus completing the original MELD score as a prognostic model in liver allocation. On the 20th anniversary of the creation of MELD score we present a brief account of its development, its use to stratify patients on the waiting list for liver transplantation as well as its adoption as liver allocation system .

Abstract

Non-alcoholic fatty liver disease (NAFLD) is reaching epidemic proportions worldwide. Collectively, Latin American countries have some of the highest obesity rates in the world and the fastest-growing prevalence of type 2 diabetes mellitus (T2DM). Since obesity and T2DM are intrinsically linked with NAFLD, epidemiological projections are worrisome. In addition to this adverse epidemiological setting, the region of Latin America faces unique challenges and obstacles to addressing the growing burden of NAFLD. In this article, on the occasion of the International NASH Day on June 10, 2021, we describe the main challenges and opportunities to improve care of people living with NAFLD in Latin America. Among the major challenges to be tackled are: lack of disease awareness, limited educational opportunities for healthcare personnel and general public, health system fragmentation, and lack of effective strategies for the prevention and effective treatment of NAFLD and common comorbidities, namely obesity and T2DM. Wide dissemination of current concepts on NAFLD, and extensive collaboration between scientific societies, governments, non-governmental organizations, pharmaceutical industry, and other stakeholders is urgently needed to advance the NAFLD public health policies agenda that allows us to address this disease with a whole of society approach.

Abstract

Background & Aims: Corticosteroids are the only effective therapy for severe alcohol-associated hepatitis (AH), defined by a model for end-stage liver disease (MELD) score >20. However, there are patients who may be too sick to benefit from therapy. Herein, we aimed to identify the range of MELD scores within which steroids are effective for AH. Methods: We performed a retrospective, international multi-center cohort study across 4 continents, including 3,380 adults with a clinical and/or histological diagnosis of AH. The main outcome was mortality at 30 days. We used a discrete-time survival analysis model, and MELD cut-offs were established using the transform-the-endpoints method. Results: In our cohort, median age was 49 (40-56) years, 76.5% were male, and 79% had underlying cirrhosis. Median MELD at admission was 24 (19-29). Survival was 88% (87-89) at 30 days, 77% (76-78) at 90 days, and 72% (72-74) at 180 days. A total of 1,225 patients received corticosteroids. In an adjusted-survival-model, corticosteroid use decreased 30-day mortality by 41% (hazard ratio [HR] 0.59; 0.47-0.74; p 51. The type of corticosteroids used (prednisone, pred-nisolone, or methylprednisolone) was not associated with sur-vival benefit (p = 0.247). Conclusion: Corticosteroids improve 30-day survival only among patients with severe AH, especially with MELD scores between 25 and 39. Lay summary: Alcohol-associated hepatitis is a condition where the liver is severely inflamed as a result of excess alcohol use. It is associated with high mortality and it is not clear whether the most commonly used treatments (corticosteroids) are effective, particularly in patients with very severe liver disease. In this worldwide study, the use of corticosteroids was associated with increased 30-day, but not 90-or 180-day, survival. The maximal benefit was observed in patients with an MELD score (a marker of severity of liver disease; higher scores signify worse disease) between 25-39. However, this benefit was lost in patients with the most severe liver disease (MELD score higher than 51). (C) 2021 European Association for the Study of the Liver. Published by Elsevier B.V.

Abstract

Non-alcoholic fatty liver disease (NAFLD) currently represents an epidemic worldwide. NAFLD is the most frequently diagnosed chronic liver disease, affecting 20-30% of the general population. Furthermore, its prevalence is predicted to increase exponentially in the next decades, concomitantly with the global epidemic of obesity, type 2 diabetes mellitus (T2DM), and sedentary lifestyle. NAFLD is a clinical syndrome that encompasses a wide spectrum of associated diseases and hepatic complications such as hepatocellular carcinoma (HCC). Moreover, this disease is believed to become the main indication for liver transplantation in the near future. Since NAFLD management represents a growing challenge for primary care physicians, the Asociación Latinoamericana para el Estudio del Hígado (ALEH) has decided to organize this Practice Guidance for the Diagnosis and Treatment of Non-Alcoholic Fatty Liver Disease, written by Latin-American specialists in different clinical areas, and destined to general practitioners, internal medicine specialists, endocrinologists, diabetologists, gastroenterologists, and hepatologists. The main purpose of this document is to improve patient care and awareness of NAFLD. The information provided in this guidance may also be useful in assisting stakeholders in the decision-making process related to NAFLD. Since new evidence is constantly emerging on different aspects of the disease, updates to this guideline will be required in future.

Abstract

Liver transplantation represents the only curative option for patients with end-stage liver disease, fulminant hepatitis and advanced hepatocellular carcinoma. Even though major advances in transplantation in the last decades have achieved excellent survival rates in the early post-transplantation period, long-term survival is hampered by the lack of improvement in survival in the late post transplantation period (over 5 years after transplantation). The main etiologies for late mortality are malignancies and cardiovascular complications. The latter are increasingly prevalent in liver transplant recipients due to the development or worsening of metabolic syndrome and all its components (arterial hypertension, dyslipidemia, obesity, renal injury, etc.). These comorbidities result from a combination of pre-liver transplant features, immunosuppressive agent side-effects, changes in metabolism and hemodynamics after liver transplantation and the adoption of a sedentary lifestyle. In this review we describe the most prevalent metabolic and cardiovascular complications present after liver transplantation, as well as proposing management strategies.

Abstract

Bacterial infections are highly prevalent and a frequent cause of hospitalization and short-term mortality in patients with cirrhosis. Due to their negative impact on survival, antibiotic prophylaxis for bacterial infections in high-risk subgroups of patients with cirrhosis has been the standard of care for decades. Patients with prophylaxis indications include those at risk for a first episode of spontaneous bacterial peritonitis (SBP) due to a low ascitic fluid protein count and impaired liver and kidney function, patients with a prior episode of SBP and those with an episode of gastrointestinal bleeding. Only prophylaxis due to gastrointestinal bleeding has a known and short-time duration. All other indications imply long-lasting exposure to antibiotics - once the threshold requirement for initiating prophylaxis is met - without standardized criteria for re-assessing antibiotic interruption. Despite the fact that the benefit of antibiotic prophylaxis in reducing bacterial infections episodes and mortality has been thoroughly reported, the extended use of antibiotics in patients with cirrhosis has also had negative consequences, including the emergence of multi-drug resistant bacteria. Currently, it is not clear whether restricting the use of broad and fixed antibiotic regimens, tailoring the choice of antibiotics to local bacterial epidemiology or selecting non-antibiotic strategies will be the preferred antibiotic prophylaxis strategy for patients with cirrhosis in the future.

Abstract

Resumen: Objetivos: Estimar la proporción de pacientes que acceden al tratamiento de la hepatitis C con antivirales de acción directa (AAD) en Argentina, y evaluar factores asociados a la falta de acceso. Métodos: Estudio de cohorte transversal que incluyó la totalidad de prescripciones consecutivas de AAD realizadas entre enero de 2016 y febrero de 2017 por centros de salud que participan en el proyecto de telemedicina ECHOTM dirigido por el Hospital Italiano de Buenos Aires. Resultados: Se incluyeron 143 prescripciones de tratamiento. El acceso global fue del 70% (IC 95%: 62-77%). Pertenecer al sistema de salud público fue el único factor independiente asociado con la falta de acceso al tratamiento [OR 4.98 (IC95% 2.05-12.09)]. Conclusión: Los pacientes con hepatitis C pertenecientes al sistema de salud público tienen 4 veces más chances de no acceder a tratamiento con AAD que los pacientes con dependencia de otros sistemas de salud (medicina privada u obras sociales). Abstract: Aims: To estimate the number of patients that have access to treatment of hepatitis C with direct-acting antivirals in Argentina and evaluate the factors associated with the lack of access. Materials and methods: A cross-sectional cohort study was conducted that included all the consecutive prescriptions of direct-acting antivirals issued at health centers that participated in the ECHOTM telemedicine project directed by the Hospital Italiano de Buenos Aires, within the time frame of January 2016 and February 2017. Results: A total of 143 treatment prescriptions were included and overall access was 70% (95% CI 62-77%). The only independent factor associated with a lack of treatment access was coverage by a public healthcare system (OR 4.98 [95% CI 2.05- 12.09]). Conclusion: Patients with hepatitis C that were covered by a public healthcare system had a 4 times higher chance of not having access to treatment with direct-acting antivirals than patients covered by other healthcare systems (private insurance or the social welfare system).

Abstract

Background: Predicting short-term mortality in patients with cirrhosis and bacterial infections is challenging. Aims: To compare the performance of various scores in predicting in-hospital mortality in this population. Methods: We performed an analysis of the multicenter prospective cohort study of patients with cirrhosis with bacterial infections throughout Argentina and Uruguay (clinicatrials.gov.NCT03919032). Patients were classified according to the CLIF criteria as having ACLF or mere acute decompensation (AD). We evaluated the performance of scores of liver disease and infection severity in predicting in-hospital mortality. MELD, MELD-Na, and Quick SOFA (qSOFA) were computed in all patients. CLIF-AD was only computed in patients without ACLF, and CLIF-ACLF only in patients with ACLF. We plotted ROC curves and estimated their area under the curve (AUROC). Results: We included 472 patients: 66% male, mean age 57 ± 12 years. Most frequent infections: SBP (30%) and urinary tract infection (25%). Overall, 332 (70%) patients had acute decompensation, and 140 (30%) ACLF. In-hospital mortality rate was 19%: 41% in patients with ACLF vs 10% in patients with AD (p

Abstract

Background: Antibiotic de-escalation is considered a safe strategy that reduces costs and the risk of multi-drug resistant infections. However, its prevalence and associated factors in real-life practice were not reported in patients with cirrhosis in Latin-America. Aims: To estimate the prevalence of antibiotic de-escalation in patients with cirrhosis in real life-practice, and to explore its associated factors. Methods: We performed an analysis of the multicenter prospective cohort study of cirrhotic patients with bacterial infections throughout Argentina and Uruguay (clinicatrials.gov NCT03919032). Patients who died in the first 72 hs from the diagnosis of the infection were excluded. In accordance with guidelines, de-escalation was defined as changing the initially antimicrobials to a narrower spectrum regimen, or suspending one or more of the empirical antibiotics, according to culture results or to other clinical reasons, either in patients with culture-positive or culture-negative bacterial infections. We used inverse probability weighting (IPW) of having a culture-positive infection to estimate its causal effect on de-escalation. Results: We included 450 patients. Most frequent infections were SBP (30.4%), and urinary tract infection (12.9%). Overall, 243 (54%) infections were culture-positive, and 207 (46%) culture-negative. De-escalation was reported in 85 patients (18.9%: 95% CI 15%-22%) at a mean of 3.3 ± 2.4 days from treatment initiation and was more frequent in culture-positive than culture-negative infections (28.4% vs 7.7%, p< 0.001). The table shows the crude analyses of variables associated with de-escalation. Culture-positive infection was strongly and independently associated with de-escalation (ORIPW 6.08; 95% CI: 2.90-12.70; p < 0.001). Conclusions: Antibiotic de-escalation was reported in one-fifth of in-patients with cirrhosis. Given that having a culture-positive infection had a strong effect on de-escalation, efforts should be made to increase the likelihood of obtaining adequate culture samples in a timely manner.

Abstract

Spontaneous bacteremia is a poorly characterized infection in patients with cirrhosis. We compared the incidence of mortality and acute kidney injury in patients with spontaneous bacterial peritonitis and spontaneous bacteremia, and identified risk factors for mortality and acute kidney injury in patients with spontaneous bacteremia. We performed a retrospective cohort study of patients with cirrhosis and spontaneous bacteremia or spontaneous bacterial peritonitis from 2008 to 2016 at Hospital Italiano, Buenos Aires. We compared the cumulative incidence of acute kidney injury and death between the two infections, and identified risk factors for these outcomes in patients with spontaneous bacteremia. Seventy-one patients with spontaneous bacteremia and 55 patients with spontaneous bacterial peritonitis were included. Most infections were nosocomial. Overall, 26% of bacteria were resistant and 11% multi-resistant. We found no significant association between acute kidney injury [subhazard ratio (sHR) 1.05 (95% confidence interval, CI 0.67–1.63, p = 0.83)] or death [sHR 1.15 (95% CI 0.60–2.20, p = 0.68)] and type of spontaneous infection in multivariate analyses adjusting for basal Model for End-Stage Liver Disease (MELD) score. In patients with spontaneous bacteremia, baseline MELD score was independently associated with acute kidney injury [sHR 1.07 (95% CI 1.03–1.11, p = 0.001)] and death [sHR 1.07 (95% CI 1.02–1.15, p = 0.03)]. Short-term acute kidney injury and mortality rates were similar in patients with spontaneous bacteremia and spontaneous bacterial peritonitis. Risk assessment of patients with spontaneous bacteremia can be performed with baseline MELD score.

Abstract

Background/objectives to compare the prognostic accuracy for 28 and 90-day transplant-free mortality of a modified CLIF-SOFA score (including a dynamic definition of acute kidney injury) with that of the classic CLIF-SOFA score and KDIGO score for acute kidney injury in patients with acute decompensation of cirrhosis. Methods A retrospective analysis of all admissions of acutely decompensated patients with cirrhosis was carried out from January 2012 to December 2014. Classic and modified CLIF-SOFA scores were analyzed, as well as acute kidney injury diagnosis using the KDIGO score regarding their accuracy for 28- and 90-day transplant free mortality prediction. Results 108 admissions were analyzed. Acute kidney injury diagnosis was met in 37 (34%) patients. Acute-on-chronic liver failure was diagnosed in 59 (55%) patients using the classic CLIF-SOFA score; and in 64 (59%) patients using the modified CLIF-SOFA score. Both CLIF-SOFA scores were highly effective in predicting 28-day transplant-free mortality (AUCROC 0.93 and 0.92, p =0.34) as well as 90-day transplant-free mortality (AUCROC 0.79 and 0.78, p =0.78). Acute kidney injury diagnosis had significantly lower accuracy in mortality assessment (28 and 90-day transplant free mortality AUCROC 0.67 [ p =0.002] and 0.63 [ p =0.02]). Conclusions To our knowledge, this is the first evidence of the limited impact of modifying the fixed kidney injury definition currently used for acute-on-chronic liver failure.
