Abstract
INTRODUCTION Circulating prostaglandin E2 levels are elevated in acutely decompensated cirrhosis and have been shown to contribute to immune suppression. Albumin binds and inactivates this hormone. Human albumin solution could thus be repurposed as an immune restorative drug in these patients.This feasibility study aims to determine whether it is possible and safe to restore serum albumin to >30 g/L and maintain it at this level in patients admitted with acute decompensated cirrhosis using repeated 20% human albumin infusions according to daily serum albumin levels. METHODS AND ANALYSIS Albumin To prevenT Infection in chronic liveR failurE (ATTIRE) stage 1 is a multicentre, open label dose feasibility trial. Patients with acutely decompensated cirrhosis admitted to hospital with a serum albumin of <30 g/L are eligible, subject to exclusion criteria. Daily intravenous human albumin solution will be infused, according to serum albumin levels, for up to 14 days or discharge in all patients. The primary end point is daily serum albumin levels for the duration of the treatment period and the secondary end point is plasma-induced macrophage dysfunction. The trial will recruit 80 patients. Outcomes will be used to assist with study design for an 866 patient randomised controlled trial at more than 30 sites across the UK. ETHICS AND DISSEMINATION Research ethics approval was given by the London-Brent research ethics committee (ref: 15/LO/0104). The clinical trials authorisation was issued by the medicines and healthcare products regulatory agency (ref: 20363/0350/001-0001). RESULTS Will be disseminated through peer reviewed journals and international conferences. Recruitment of the first participant occurred on 26/05/2015. TRIAL REGISTRATION NUMBER The trial is registered with the European Medicines Agency (EudraCT 2014-002300-24) and has been adopted by the NIHR (ISRCTN 14174793). This manuscript refers to V.4.0 of the protocol; Pre-results.

Abstract
Qualitative and quantitative changes in gut microbiota play a very important role in cirrhosis. Humans harbour around 100 quintillion gut bacteria, thus representing around 10 times more microbial cells than eukaryotic ones. The gastrointestinal tract is the largest surface area in the body and it is subject to constant exposure to these living microorganisms. The existing symbiosis, proven by the lack of proinflammatory response against commensal bacteria, implies the presence of clearly defined communication lines that contribute to the maintenance of homeostasis of the host. Therefore, alterations of gut flora seem to play a role in the pathogenesis and progress of multiple liver and gastrointestinal diseases. This has made its selective modification into an area of high therapeutic interest. Bacterial translocation is defined as the migration of bacteria or bacterial products from the intestines to the mesenteric lymph nodes. It follows that alteration in gut microbiota have shown importance, at least to some extent, in the pathogenesis of several complications arising from terminal liver disease, such as hepatic encephalopathy, portal hypertension and spontaneous bacterial peritonitis. This review sums up, firstly, how liver disease can alter the common composition of gut microbiota, and secondly, how this alteration contributes to the development of complications in cirrhosis.

Abstract
The incidence of end-stage liver disease (ESLD) is increasing and many of these patients may be considered for orthotopic liver transplantation. As patients with ESLD are at risk of a number of infections, infectious disease physicians should be aware of the management of these infections in order to provide optimal patient care and ensure transplantation success. We present a review of the literature pertaining to infectious disease considerations in the liver transplant candidate. It highlights several topics with recent developments including the management of hepatitis C virus infection prior to transplantation, treatment of hepatitis B virus infection, colonization and infection with multidrug resistant organisms, and management of spontaneous bacterial peritonitis.

Abstract
BACKGROUND Spontaneous bacterial peritonitis is frequently a fatal infection in patients with liver cirrhosis. We investigated if nuclear dot protein 52kDa (NDP52), a negative regulator of toll-like receptor (TLR) signalling and autophagy adaptor protein, might be involved. METHODS Two cohorts comprising 152 (derivation cohort) and 198 patients (validation cohort) with decompensated liver cirrhosis and 168 healthy controls were genotyped for the rs2303015 polymorphism in the NDP52 gene and prospectively followed-up for spontaneous bacterial peritonitis. RESULTS Overall, 57 (38%) patients in the derivation cohort and 77 (39%) in the validation cohort had spontaneous bacterial peritonitis. Cirrhosis was due to alcohol abuse in 57% of the derivation and 66% of the validation cohort. In patients with alcoholic cirrhosis, patients with spontaneous bacterial peritonitis had an increased frequency of the NDP52 rs2303015 minor variant in the derivation (p=0.04) and in the validation cohort (p=0.01). Multivariate analysis confirmed this minor variant (odds ratio 4.7, p=0.002) and the TLR2 -16934 TT variant (odds ratio 2.5, p=0.008) as risk factors for spontaneous bacterial peritonitis. In addition, presence of the NDP52 minor variant affected survival negatively. CONCLUSION Presence of the NDP52 rs2303015 minor variant increases the risk for spontaneous bacterial peritonitis in patients with alcoholic cirrhosis.

Abstract
Recently, there has been a significant increase in the prevalence of chronic liver disease in the UK, and as a result, hospital admissions and deaths due to liver disease have also increased. The 2013 National Confidential Enquiry into Patient Outcome and Death (NCEPOD) of patients with alcohol-related liver disease (ARLD) found that less than half the number of patients who died from ARLD received 'good care', and avoidable deaths were identified. In order to improve the care of patients admitted with ARLD, the NCEPOD report recommended that a 'toolkit' for the acute management of patients admitted with decompensated ARLD be developed and made widely available. As a result, we have developed a 'care bundle' for patients admitted with decompensated cirrhosis (of all aetiologies) to ensure that effective evidence-based treatments are delivered within the first 24 h. This care bundle provides a checklist to ensure that all appropriate investigations are undertaken when a patient with decompensated cirrhosis presents and provides clinicians with clear guidance on the initial management of alcohol withdrawal, infection, acute kidney injury, gastrointestinal bleeding and encephalopathy. The first 24 h are particularly important, as early intervention can reduce mortality and shorten hospital stay, and specialist gastroenterology/liver advice is not always available during this period. This review will discuss the care bundle and the evidence base behind the treatment recommendations made.

Abstract
Ascites is the most frequent complication of patients with cirrhosis. Ascites is related to increased renal sodium retention as a result of increased activity of the renin-angiotensin-aldosterone system in response to marked vasodilation of the splanchnic circulation. Management of uncomplicated ascites is based on a low-sodium diet and diuretics. However, approximately 10% of patients develop refractory ascites during follow-up, which is associated with a poor prognosis. The treatment of choice in patients with refractory ascites is large-volume paracentesis associated with intravenous albumin. Moreover, patients who develop refractory ascites should be considered as candidates for liver transplantation. Patients with ascites are all at risk of developing spontaneous bacterial peritonitis (SBP). SBP is a common infection in patients with cirrhosis with a risk of mortality of 20%. Empirical antibiotics are the treatment of choice in patients with SBP but differ depending on the acquisition site of infection, because nosocomial infections have a higher risk of being caused by multiresistant bacteria. In addition to antibiotic treatment, all patients with SBP should also receive intravenous albumin. This review summarizes the management of uninfected ascites and SBP in cirrhosis.

Abstract
Over the past two decades, there has been a dramatic worldwide increase in both the incidence and severity of Clostridium difficile infection (CDI). Paralleling the increased incidence of CDI in the general population, there has been increased interest in CDI among patients with liver disease, particularly in those with liver cirrhosis and post liver transplantation. MEDLINE and several other electronic databases from January 1995 to December 2014 were searched in order to identify potentially relevant literature. Patients with cirrhosis and liver transplant recipients are at high risk for the development CDI because of antibiotics and proton pump inhibitors use, frequent and prolonged hospitalization, immunosuppressant therapy, and multiple comorbidities. Enzyme immunoassay to detect C. difficile toxins A and B in stool remains the most widely used test for CDI diagnosis, although, more recently, polymerase chain reaction (PCR)-based assays have become the preferred diagnostic test in many laboratories. Metronidazole and vancomycin, given orally, have proved to be effective in the treatment of CDI. Both cirrhotic patients and liver transplant recipients with CDI have longer length of hospital stay, increased mortality, and higher healthcare costs than those without CDI. A rapid diagnosis and adequate therapy of CDI are of paramount importance to improve liver disease patients' outcome. The aim of this review is to provide up-to-date information on the epidemiology, risk factors, pathogenesis, treatment, and outcomes in liver disease patients with CDI.

Abstract
BACKGROUND Infection is the most common cause of mortality in end-stage liver disease (ESLD). The impact of obesity on infection risk in ESLD is not established. AIM To characterise the impact of obesity on infection risk in ESLD. METHODS We evaluated the association between infection and obesity in patients with ESLD. Patients grouped as non-obese, obesity class I-II and obesity class III were studied using the Nationwide Inpatient Sample. Validated diagnostic code based algorithms were utilised to determine weight category and infections, including bacteraemia, skin/soft tissue infection, urinary tract infection (UTI), pneumonia/respiratory infection, Clostridium difficile infection (CDI) and spontaneous bacterial peritonitis (SBP). Risk factors for infection and mortality were assessed using multivariable logistic regression analysis. RESULTS Of 115 465 patients identified, 100 957 (87.5%) were non-obese and 14 508 (12.5%) were obese, with 9489 (8.2%) as obesity class I-II and 5019 (4.3%) as obesity class III. 37 117 patients (32.1%) had an infection diagnosis. Infection was most prevalent among obesity class III (44.0%), followed by obesity class I-II (38.9%) and then non-obese (31.9%). In multivariable modelling, class III obesity (OR = 1.41; 95% CI 1.32-1.51; P < 0.001), and class I-II obesity (OR = 1.08; 95% CI 1.01-1.15; P = 0.026) were associated with infection. Compared to non-obese patients, obese individuals had greater prevalence of bacteraemia, UTI, and skin/soft tissue infection as compared to non-obese patients. CONCLUSIONS Obesity is newly identified to be independently associated with infection in end-stage liver disease. The distribution of infection sites varies based on weight category.

Abstract
The early detection of bacterial infections and hepatocellular carcinoma (HCC) could ameliorate the prognosis of cirrhosis. C-reactive protein and procalcitonin are under investigation in the setting of cirrhosis as markers of sepsis. In the attempt to discriminate bacterial infection from systemic inflammation, the role of novel biomarkers such as lypopolysaccharide binding-protein, mid-regional fragment of pro-adrenomedullin and delta neutrophil index are currently in development. Concerning HCC, many studies attempted to evaluate biomarkers in the hope of ameliorating the accuracy of the surveillance based on ultrasound. The use of α-fetoprotein (AFP) has been extensively investigated, as well as other biomarkers expressed in the serum of HCC patients like lens culinaris agglutinin-reactive fraction of AFP, des-γ-carboxy prothrombin, glypican-3, α-l-fucosidase and their combined use.

Abstract
The use of norfloxacin either as primary or secondary prophylaxis of bacterial infections in advanced cirrhosis has improved patient’s survival. This may be explained not only due to a significant decrease in the number of infections, but also because of a direct immunomodulatory effect. Selective intestinal decontamination with norfloxacin reduces translocation of either viable bacteria or bacteria-driven products from the intestinal lumen. In addition, norfloxacin directly modulates the systemic inflammatory response. The pro-inflammatory cytokine profile secreted by neutrophils from these patients shows a close, significant, and inverse correlation with serum norfloxacin levels. Similar effects have been described with other quinolones in different clinical conditions. Although the underlying mechanisms are not well defined for most of the antibiotics, the pathways triggered for norfloxacin to induce such immunomodulatory effects involve the down-regulation of pro-inflammatory inducible nitric oxide synthase, cyclooxygenase-2, and NF-κB and the up-regulation of heme-oxygenase 1 and IL-10 expression. The knowledge of these immunomodulatory effects, additional to their bactericidal role, improves our comprehension of the interaction between antibiotics and the cellular host response and offer new possibilities for the development of new therapeutic strategies to manage and prevent bacterial infections in cirrhosis.

Abstract
BACKGROUND The prognostic impact of the first ever episode of spontaneous bacterial peritonitis (SBP) on patient outcomes is not well described. Our aim was to compare the clinical outcomes of cirrhotic patients with ascites, and with or without a first episode of SBP. METHODS Consecutive patients with cirrhosis and ascites were prospectively enrolled. Demographics, liver and renal function, and hemodynamics were documented at baseline, at resolution of SBP, and thereafter at 4 monthly intervals for 12 months. Complications of cirrhosis and survival were noted. RESULTS Twenty-nine cirrhotic patients with a first ever episode of SBP (group A) and 123 control patients slightly younger but similar in gender who never had SBP (group B) were enrolled. At SBP diagnosis, group A had worse liver and renal function (Model of End-Stage Liver Disease : 21.1±10.6 vs. 14.4±5.0), lower serum sodium concentrations, and a more hyperdynamic circulation compared with group B (all P<0.001). SBP resolution resulted in improvement in all measures to baseline levels. During follow-up, group A required more frequent hospital admissions than group B (58% vs. 43%), developed more cirrhotic complications, including further SBP (31% vs. 3%*), hyponatremia (12% vs. 0.8%*), acute kidney injury (50% vs. 23%*), hepatorenal syndrome type 1 (46% vs. 7%*), liver transplantation (62% vs. 30%*), and had a worse overall 1-year survival (38% vs. 70%*) (*P<0.05). CONCLUSIONS A first SBP episode is commonly followed by multiple complications, and overall worse prognosis. Consideration should be given to assess cirrhotic patients for liver transplant after the first episode of SBP.

Abstract
Liver cirrhosis is the final stage of chronic liver disease of any causes, in which the defensive reaction to infections is reducing. Patients with liver cirrhosis are at an increased risk of infections, sepsis and death. Neutrophils are an essential component of the innate immune response and the first line of defense to resist all kinds of detrimental factor, and participate in specific immunity. Immune dysfunction in cirrhosis is associated with neutrophil dysfunction. This paper reviews the neutrophil dysfunction and its pathogenesis in liver cirrhosis.

Abstract
AIM: To investigate the microbiological characteristics and drug resistance in liver cirrhosis patients with spontaneous peritonitis.
METHODS: We analyzed the data of patients with liver cirrhosis and abdominal infection at the First Affiliated Hospital of Zhejiang University between January 2011 and December 2013. Pathogens present in the ascites were identified, and their sensitivity to various antibiotics was determined.
RESULTS: We isolated 306 pathogenic bacteria from 288 cases: In 178 cases, the infection was caused by gram-negative strains (58.2%); in 85 cases, gram-positive strains (27.8%); in 9 cases, fungi (2.9%); and in 16 cases, more than one pathogen. The main pathogens were Escherichia coli (E. coli) (24.2%), Klebsiella pneumoniae (18.9%), Enterococcus spp. (11.1%), and Staphylococcus aureus (7.5%). Of the 306 isolated pathogens, 99 caused nosocomial infections and 207 caused community-acquired and other infections. The E. coli and K. pneumoniae strains produced more extended-spectrum β-lactamases in cases of nosocomial infections than non-nosocomial infections (62.5% vs 38%, P < 0.013; 36.8% vs 12.8%, P < 0.034, respectively). The sensitivity to individual antibiotics differed between nosocomial and non-nosocomial infections: Piperacillin/tazobactam was significantly more effective against non-nosocomial E. coli infections (4% vs 20.8%, P < 0.021). Nitrofurantoin had stronger antibacterial activity against Enterococcus species causing non-nosocomial infections (36.4% vs 86.3%, P < 0.009).
CONCLUSION: The majority of pathogens that cause abdominal infection in patients with liver cirrhosis are gram-negative, and drug resistance is significantly higher in nosocomial infections than in non-nosocomial infections.

Abstract
Spontaneous bacterial peritonitis (SBP) is a severe complication occurring in patients with cirrhosis, and is associated with high mortality. Liver transplantation should be considered after a first episode of SBP. Gram-negative bacilli are the major cause of SBP, however there is an increasing trend of Gram-positive cocci related SBP. Management includes empirical antibiotic treatment and albumin infusion. The choice of antibiotics depends on the site of acquisition (community-acquired vs nosocomial or health-care associated infection) and local resistance profile, due to the emergence of drug-resistant bacteria. Secondary prophylaxis is recommended after resolution of SBP and reduces recurrence and mortality. Primary prophylaxis in patients with low protein ascites (<15 g/L) should be restricted to patients with severe cirrhosis awaiting for liver transplantation.

Abstract
OBJECTIVES Longitudinal, population-based data on the occurrence, localization, and severity of bacterial infections over time in patients with alcoholic compared with nonalcoholic cirrhosis are limited. MATERIALS AND METHODS All patients with incident cirrhosis diagnosed in 2001-2010 (area of 600,000 inhabitants) were retrospectively identified. All bacterial infections resulting in or occurring during an inpatient hospital episode during this period were registered. The etiology of cirrhosis (alcoholic vs. nonalcoholic), infection localization, and outcome as well as bacterial resistance patterns were analyzed. Patients were followed until death, transplant, or the end of 2011. RESULTS In all, 633 cirrhotics (363 alcoholic, 270 nonalcoholic) experienced a total of 398 infections (2276 patient-years). Among patients diagnosed with cirrhosis each year from 2001 to 2010, increasing trends were noted in the occurrence of infection (from 13 to 27%, P<0.001) and infection-related in-hospital mortality (from 2 to 7%, P=0.05), the latter mainly in the alcoholic group. Although alcoholic etiology was related to the occurrence of more frequent infection (Kaplan-Meier, P<0.001), this relationship was not significant after adjustment for confounders in Cox regression analysis (P=0.056). Resistance to piperacilin-tazobactam and carbapenems was more common in infections occurring in alcoholic versus nonalcoholic cirrhosis (13 vs. 5%, P=0.057 and 12 vs. 2%, P=0.009). Alcoholic etiology predicted pneumonia and infections caused by Gram-positive bacteria in multivariate analysis (P<0.05 for both). CONCLUSION In a population-based cirrhotic cohort, bacterial infections increased over time, which, in the case of alcoholic cirrhosis, was associated with pneumonia and bacterial resistance to antibiotics. However, alcoholic etiology was not related indepedently to the occurrence of bacterial infections.

Abstract
OBJECTIVE Population-based data on the impact of bacterial infections on the course of compensated and decompensated cirrhosis as well as the occurrence, predictors of infection-related acute-on-chronic liver failure (ACLF) and its fatal outcome are limited. MATERIAL AND METHODS All patients with incident cirrhosis in the period 2001-2010, residing in an area of 600,000 inhabitants, were retrospectively identified. All serious bacterial infections (resulting in or occurring during an inpatient hospital episode) during this period were analyzed. Infection site and acquisition type, comorbid illness (Charlson comorbidity index) and infection severity features were analyzed. Patients were followed up until death, transplant, or the end of 2011. RESULTS Overall, 398 serious bacterial infections occurred in 241/633 (38%) patients (106/332 diagnosed with compensated and 135/301 with decompensated disease; follow-up time was 2276 patient-years). ACLF occurred in 95/398 (24%) serious infections with an in-hospital mortality of 50%. In logistic regression analysis, the model for end-stage liver disease score, active alcohol misuse and healthcare-associated infections were predictors of infection-related ACLF (p < 0.05 for all). In-hospital mortality in infections with ACLF was related to albumin levels, Charlson comorbidity index >1 and occurrence of one or more organ failures (p > 0.05 for all). In Cox regression analysis, infection-related ACLF was an independent negative predictor of transplant-free survival in decompensated patients (p = 0.049). CONCLUSIONS In a population-based cirrhotic cohort, infection-related ACLF was a negative predictor of survival in decompensated disease. Infection-related ACLF was frequent and related to cirrhosis severity and infection acquisition type, as well as to high inpatient mortality, in particular in patients with significant comorbidity.

Abstract
Background & Aims Vitamin D, best known to regulate bone mineralization, has numerous additional roles including regulation inflammatory pathways. Recently, an increased incidence of 25-hydroxyvitamin D3 (25(OH)D3) deficiency has been found in subjects suffering from liver diseases. We here investigated if low vitamin D levels might be associated with prognosis, inflammation and infectious complications in patients with cirrhosis. Methods We performed a prospective cohort study investigating the relation between 25(OH)D3 levels and stages of cirrhosis, mortality and complications of cirrhosis, including infections. Results 251 patients with cirrhosis were enrolled into the present prospective cohort study. 25(OH)D3 levels were quantified by radioimmunoassay from serum samples obtained at study inclusion. The mean follow-up time was 411 ± 397 days with a range of 1-1382 days. 30 (12.0%) patients underwent liver transplantation and 85 (33.8%) individuals died within the study. The mean serum 25(OH)D3 concentration was 8.93 ± 7.1 ng/ml with a range of 1.0 to 46.0 ng/ml. 25(OH)D3 levels differed significantly between Child Pugh scores and showed a negative correlation with the model of end stage liver disease (MELD) score. Patients with decompensated cirrhosis and infectious complications, had significantly lower 25(OH)D3 levels compared to subjects without complications. Low 25(OH)D3 was associated with mortality in uni- as well as multivariate Cox regression models. Conclusions 25(OH)D3 deficiency is associated with advanced liver disease and low 25(OH)D3 levels are an indicator for a poor outcome and are associated with infectious complications.

Risk of Bacterial Infection in Patients With Cirrhosis and Acute Variceal Hemorrhage, Based on Child-Pugh Class, and Effects of Antibiotics. Clin Gastroenterol Hepatol 2015; 13:1189-96.e2.

Abstract
BACKGROUND & AIMS Antibiotics frequently are overused and are associated with serious adverse events in patients with cirrhosis. However, these drugs are recommended for all patients presenting with acute variceal hemorrhage (AVH). We investigated whether patients should be stratified for antibiotic prophylaxis based on Child-Pugh scores, to estimate risks of bacterial infection, rebleeding, and mortality, and whether antibiotics have equal effects on patients of all Child-Pugh classes. We performed a sensitivity analysis using model for end-stage liver disease (MELD) scores. METHODS In a retrospective study, we analyzed data from 381 adult patients with cirrhosis and AVH (70% men; mean age, 56 y), admitted from 2000 through 2009 to 2 tertiary care hospitals in Edmonton, Alberta, Canada. We excluded patients with bacterial infection on the day of AVH. The association between antibiotic prophylaxis and outcomes was adjusted by liver disease severity and by a propensity score. RESULTS The patients included in the study had mean MELD scores of 16, and 54% received antibiotic prophylaxis. Overall, antibiotic therapy was associated with lower risks of infection (adjusted odds ratio, 0.37; 95% confidence interval, 0.91-0.74) and mortality (adjusted odds ratio, 0.63; 95% confidence interval, 0.31-1.29). Among patients categorized as Child-Pugh class A given antibiotics, only 2% developed infections and the mortality rate was 0.4%. Among patients categorized as Child-Pugh class B given antibiotics, 6% developed infections, compared with 14% of patients who did not receive antibiotics; antibiotics did not affect mortality. Administration of antibiotics to patients categorized as Child-Pugh class C reduced infections and mortality by approximately 50%, compared with patients who did not receive antibiotics. MELD scores were not as useful as Child-Pugh class in identifying patients at risk for infection. CONCLUSIONS Based on a retrospective analysis of patients with cirrhosis and AVH, those categorized as Child-Pugh class A had lower rates of bacterial infection and lower mortality rates in the absence of antibiotic prophylaxis than patients categorized as classes B or C. The recommendation for routine antibiotic prophylaxis for this subgroup requires further evaluation.

Abstract
BACKGROUND Spontaneous bacterial peritonitis (SBP) is a severe and often fatal infection in patients with cirrhosis and ascites. AIM To review the known and changing bacteriology, risk factors, ascitic fluid interpretation, steps in performing paracentesis, treatment, prophylaxis and evolving perspectives related to SBP. METHODS Information was obtained from reviewing medical literature accessible on PubMed Central. The search term 'spontaneous bacterial peritonitis' was cross-referenced with 'bacteria', 'risk factors', 'ascites', 'paracentesis', 'ascitic fluid analysis', 'diagnosis', 'treatment', 'antibiotics', 'prophylaxis', 'liver transplantation' and 'nutrition'. RESULTS Gram-positive cocci (GPC) such as Staphylococcus, Enterococcus as well as multi-resistant bacteria have become common pathogens and have changed the conventional approach to treatment of SBP. Health care-associated and nosocomial SBP infections should prompt greater vigilance and consideration for alternative antibiotic coverage. Acid suppressive and beta-adrenergic antagonist therapies are strongly associated with SBP in at-risk individuals. CONCLUSIONS Third-generation, broad-spectrum cephalosporins remain a good initial choice for SBP treatment. Levofloxacin is an acceptable alternative for patients not receiving long-term flouroquinolone prophylaxis or for those with a penicillin allergy. For uncomplicated SBP, early oral switch therapy is reasonable. Alternative antibiotics such as pipercillin-tazobactam should be considered for patients with nosocomial SBP or for patients who fail to improve on traditional antibiotic regimens. Selective albumin supplementation remains an important adjunct in SBP treatment. Withholding acid suppressive medication deserves strong consideration, and discontinuing beta-adrenergic antagonist therapy in patients with end-stage liver disease and resistant ascites is standard care. Liver transplant evaluation should be undertaken for patients who develop SBP barring contraindications.

Abstract
Background The spread of multi-resistant infections represents a continuously growing problem in cirrhosis, particularly in patients in contact with the healthcare environment. Aim Our prospective study aimed to analyze epidemiology, prevalence and risk factors of multi-resistant infections, as well as the rate of failure of empirical antibiotic therapy in cirrhotic patients. Methods All consecutive cirrhotic patients hospitalized between 2008 and 2013 with a microbiologically-documented infection (MDI) were enrolled. Infections were classified as Community-Acquired (CA), Hospital-Acquired (HA) and Healthcare-Associated (HCA). Bacteria were classified as Multidrug-Resistant (MDR) if resistant to at least three antimicrobial classes, Extensively-Drug-Resistant (XDR) if only sensitive to one/two classes and Pandrug-Resistant (PDR) if resistant to all classes. Results One-hundred-twenty-four infections (15% CA, 52% HA, 33% HCA) were observed in 111 patients. Urinary tract infections, pneumonia and spontaneous bacterial peritonitis were the more frequent. Forty-seven percent of infections were caused by Gram-negative bacteria. Fifty-one percent of the isolates were multi-resistant to antibiotic therapy (76% MDR, 21% XDR, 3% PDR): the use of antibiotic prophylaxis (OR = 8.4; 95%CI = 1.03-76; P = 0,05) and current/recent contact with the healthcare-system (OR = 3.7; 95%CI = 1.05-13; P = 0.04) were selected as independent predictors. The failure of the empirical antibiotic therapy was progressively more frequent according to the degree of resistance. The therapy was inappropriate in the majority of HA and HCA infections. Conclusions Multi-resistant infections are increasing in hospitalized cirrhotic patients. A better knowledge of the epidemiological characteristics is important to improve the efficacy of empirical antibiotic therapy. The use of preventive measures aimed at reducing the spread of multi-resistant bacteria is also essential.

Recently, important changes have been reported regarding the epidemiology of bacterial infections in liver cirrhosis. There is an emergence of multiresistant bacteria in many European countries and also worldwide, including the United States and South Korea. The classic empirical antibiotic treatment (third-generation cephalosporins, e.g., ceftriaxone, cefotaxime or amoxicillin-clavulanic acid) is still effective in infections acquired in the community, but its failure rate in hospital acquired infections and in some health-care associated infections is high enough to ban its use in these settings. The current editorial focuses on the different epidemiology of bacterial infections in cirrhosis across countries and on its therapeutic implications.

Abstract
Bacterial infection is an important cause of death in patients with liver cirrhosis. The aim of this study was to investigate the clinical characteristics and prognostic impact of bacterial infection in hospitalized patients with alcoholic liver disease (ALD). We retrospectively analyzed data from 409 patients consecutively admitted to a tertiary referral center with ALD diagnosis. Of a total of 544 admissions, 133 (24.4%) cases presented with bacterial infection, of which 116 were community-acquired whereas 17 were hospital-acquired. The common types of infection were pneumonia (38%), biliary tract infection (17%), soft tissue infection (12%), and spontaneous bacterial peritonitis (9%). Diabetes, serum Na <135 mM/L, albumin <2.5 g/dL, C-reactive protein ≥20 mg/L, systemic inflammatory response syndrome (SIRS) positivity were independently associated with bacterial infection in patients with ALD. Overall 30-day and 90-day mortalities in patients with bacterial infection were significantly (P < 0.001) higher than those without infection (22.3% vs. 5.1% and 32.3% vs. 8.2%, respectively). Furthermore, bacterial infection (HR, 2.2; 95% CI, 1.049-4.579, P = 0.037), SIRS positivity (HR, 2.5; 95% CI, 1.240-4.861, P = 0.010), Maddrey's discriminant function score ≥32 (HR, 2.3; 95% CI, 1.036-5.222, P = 0.041), and hemoglobin <12 g/dL (HR, 2.4; 95% CI, 1.081-5.450, P = 0.032) were independent predictors of short-term mortality. In conclusion, bacterial infection and SIRS positivity predicted short-term prognosis in hospitalized patients with ALD. A thorough evaluation at admission or on clinical deterioration is required to detect possible infection with prompt management.

Abstract
The late and fast developments in the field of viral hepatitis were highly expected in the 2014 AASLD Liver Meeting®. Several combinations using direct acting antivirals (DAAs) showed high rates of sustained virological response (∼95%). Importantly, high cure rates were also demonstrated in patients with previous treatment failures, decompensated cirrhosis and hepatitis C recurrence after transplantation, making it clear that the interferon era is over (not so clear for ribavirin, which might still have a role in difficult-to-treat populations). Importantly, sustained virological response was associated with an improvement in liver function (MELD and Child-Pugh scores) in patients with advanced liver disease. In the field of liver cirrhosis, there were relevant data assessing the optimal empirical antibiotic therapy in patients with spontaneous bacterial peritonitis and high risk of resistant bacteria, as well as studies evaluating the role of terlipressin in type I hepatorenal syndrome and in septic shock. Regarding hepatic encephalopathy, two randomized trials suggest that the manipulation of the microbioma in patients with cirrhosis may have a role in the management of this complication. Some novel data on NASH support the beneficial effect of bariatric surgery (after failure of lifestyle intervention) in morbid obese patients with such diagnosis: clinical and histological improvements after surgery were evident in most patients with sufficient follow-up. A few controlled studies focused on the treatment of severe acute alcoholic hepatitis. Finally, several studies on hepatocellular carcinoma (HCC) were presented, covering topics such as ultrasound screening in cirrhosis, cryoablation treatment of early HCC and the relevance of downstaging in patients with HCC awaiting liver transplantation.

Abstract
BACKGROUND & AIMS Bacterial infections, particularly repeated infections, are significant causes of morbidity and mortality among patients with cirrhosis. We investigated and characterized risk factors for repeat infections in these patients. METHODS In a prospective study, we collected data from 188 patients hospitalized with cirrhosis and infections and enrolled in the North American Consortium for the Study of End-Stage Liver Disease (12 centers). Patients were followed up for 6 months after hospital discharge and data were analyzed on type of infections and factors associated with subsequent infections. RESULTS Six months after hospital discharge, 14% of subjects had received liver transplants, 27% died, and 59% were alive without liver transplantation. After discharge, 45% had subsequent infections, but only 26% of the subsequent infections occurred at the same site. Compared with patients not re-infected, patients with repeat infections were older and a higher proportion used proton pump inhibitors (PPIs) (P = .006), rifaximin (P < .001), or prophylactic therapy for spontaneous bacterial peritonitis (SBP) (P < .001). Logistic regression showed that SBP prophylaxis (odds ratio [OR], 3.44; 95% confidence interval [CI], 1.56-7.63), PPI use (OR, 2.94; 95% CI, 1.39-6.20), SBP at hospital admission (OR, 0.37; 95% CI, 0.15-0.91), and age (OR, 1.06; 95% CI, 1.02-1.11) were independent predictors of subsequent infections. CONCLUSIONS Patients hospitalized with cirrhosis and infections are at high risk for subsequent infections, mostly at different sites, within 6 months of index infection resolution. Those at highest risk include previously infected older patients receiving PPIs and/or SBP prophylaxis, although these associations do not prove that these factors cause the infections. New strategies are needed to prevent infections in patients with cirrhosis.

Abstract
AIM: To analyze whether prompt and appropriate empirical antibiotic (AEA) use is associated with mortality in cirrhotic patients with bacteremia.
METHODS: A total of 102 episodes of bacteremia in 72 patients with cirrhosis were analyzed. AEA was defined as a using or starting an antibiotic appropriate to the isolated pathogen at the time of bacteremia. The primary endpoint was 30-d mortality.
RESULTS: The mortality rate at 30 d was 30.4% (31/102 episodes). Use of AEA was associated with better survival at 30 d (76.5% vs 46.9%, P = 0.05), and inappropriate empirical antibiotic (IEA) use was an independent factor associated with increased mortality (OR = 3.24; 95%CI: 1.50-7.00; P = 0.003, adjusted for age, sex, Child-Pugh Class, gastrointestinal bleeding, presence of septic shock). IEA use was more frequent when the isolated pathogen was a multiresistant pathogen, and when infection was healthcare-related or hospital-acquired.
CONCLUSION: AEA use was associated with increased survival of cirrhotic patients who developed bacteremia. Strategies for AEA use, tailored according to the local epidemiological patterns, are needed to improve survival of cirrhotic patients with bacteremia.

Abstract
Spontaneous bacterial peritonitis (SBP) is a frequent, life-threatening bacterial infection in patients with liver cirrhosis and ascites. Portal hypertension leads to increased bacterial translocation from the intestine. Failure to eliminate invading pathogens due to immune defects associated with advanced liver disease on the background of genetic predisposition may result in SBP. The efficacy of antibiotic treatment and prophylaxis has declined due to the spread of multi-resistant bacteria. Patients with nosocomial SBP and with prior antibiotic treatment are at a particularly high risk for infection with resistant bacteria. Therefore, it is important to adapt empirical treatment to these risk factors and to the local resistance profile. Rifaximin, an oral, non-absorbable antibiotic, has been proposed to prevent SBP, but may be useful only in a subset of patients. Since novel antibiotic classes are lacking, we have to develop prophylactic strategies which do not induce bacterial resistance. Farnesoid X receptor agonists may be a candidate, but so far, clinical studies are not available. New diagnostic tests which can be carried out quickly at the patient’s site and provide additional prognostic information would be helpful. Furthermore, we need tools to predict antibiotic resistance in order to tailor first-line antibiotic treatment of spontaneous bacterial peritonitis to the individual patient and to reduce mortality.

Abstract
BACKGROUND Patients with liver cirrhosis have a highly elevated risk of developing bacterial infections that significantly decrease survival rates. One of the most relevant infections is spontaneous bacterial peritonitis (SBP). Recently, NOD2 germline variants were found to be potential predictors of the development of infectious complications and mortality in patients with cirrhosis. The aim of the INCA (Impact of NOD2 genotype-guided antibiotic prevention on survival in patients with liver Cirrhosis and Ascites) trial is to investigate whether survival of this genetically defined high-risk group of patients with cirrhosis defined by the presence of NOD2 variants is improved by primary antibiotic prophylaxis of SBP. METHODS/DESIGN The INCA trial is a double-blind, placebo-controlled clinical trial with two parallel treatment arms (arm 1: norfloxacin 400 mg once daily; arm 2: placebo once daily; 12-month treatment and observational period). Balanced randomization of 186 eligible patients with stratification for the protein content of the ascites (<15 versus ≥ 15 g/L) and the study site is planned. In this multicenter national study, patients are recruited in at least 13 centers throughout Germany. The key inclusion criterion is the presence of a NOD2 risk variant in patients with decompensated liver cirrhosis. The most important exclusion criteria are current SBP or previous history of SBP and any long-term antibiotic prophylaxis. The primary endpoint is overall survival after 12 months of treatment. Secondary objectives are to evaluate whether the frequencies of SBP and other clinically relevant infections necessitating antibiotic treatment, as well as the total duration of unplanned hospitalization due to cirrhosis, differ in both study arms. Recruitment started in February 2014. DISCUSSION Preventive strategies are required to avoid life-threatening infections in patients with liver cirrhosis, but unselected use of antibiotics can trigger resistant bacteria and worsen outcome. Thus, individualized approaches that direct intervention only to patients with the highest risk are urgently needed. This trial meets this need by suggesting stratified prevention based on genetic risk assessment. To our knowledge, the INCA trial is first in the field of hepatology aimed at rapidly transferring and validating information on individual genetic risk into clinical decision algorithms.

Abstract
BACKGROUND Proton pump inhibitors (PPI) are widely used in patients with liver diseases. Within the last years, there have been concerns about the PPI use as they may promote infections in patients with cirrhosis. AIM As there are sparse data of the prognostic relevance of PPI treatment, to perform a prospective study investigating the relation of PPI treatment and overall survival (OS) in cirrhotic individuals. METHODS Patients with cirrhosis were enrolled and followed prospectively. The primary end point was OS. PPI treatment and additional clinical and laboratory data were assessed at the day of the study inclusion. The time until the end point death was assessed and the individual risks were calculated with Cox regression analyses. RESULTS A total of 272 patients were included and 213 individuals (78.3%) were on PPI treatment. In multivariate logistic regression analysis, PPI treatment was associated with higher MELD scores (P = 0.027) and ascites (P = 0.039). In a multivariate Cox regression model, PPI use was an independent predictor of mortality (hazard ratio 2.330, 95% confidence interval 1.264-4.296, P = 0.007) in addition to the model of end-stage liver disease (MELD) score, hepatocellular carcinoma and hepatic decompensation. CONCLUSIONS PPI use is an independent risk factor for mortality in patients with cirrhosis. Although a causative role for increased mortality in patients taking PPI is still missing, the prescription of PPI in cirrhotics should be considered carefully taking into account its potential adverse effects.

Abstract
BACKGROUND & AIMS Probiotics can prevent pathological bacterial translocation in cirrhosis by modulating intestinal microbiota and improving gut barrier and immune disturbances. To evaluate the effect of probiotic VSL#3 on bacterial translocation, intestinal microbiota, gut barrier and inflammatory response in rats with experimental cirrhosis. METHODS Forty-six Sprague-Dawley rats with CCl4 -induced cirrhosis were randomized into two groups: VSL#3 group (n = 22) that received VSL#3 in drinking water, and water group (n = 24) that received water only. Treatment began at week 6 of cirrhosis induction and continued until laparotomy, performed 1 week after development of ascites or at week 20. A control group included 11 healthy rats. At this study end, we evaluated bacterial translocation, intestinal flora, intestinal barrier (ileal claudin-2 and 4, β-defensin-1, occludin and malondialdehyde as index of oxidative damage) and serum cytokines. RESULTS Mortality during this study was similar in the VSL#3 group (10/22, 45%) and the water group (10/24, 42%) (P = 1). The incidence of bacterial translocation was 1/12 (8%) in the VSL#3 group, 7/14 (50%) in the water group (P = 0.03 vs. VSL#3 group) and 0/11 in the control group (P = 0.008 vs. water group). The concentration of ileal and caecal enterobacteria and enterococci was similar in the two groups of cirrhotic rats. The ileal occludin concentration was higher and ileal malondialdehyde and serum levels of TNF-α were lower in the VSL#3 group than in the water group (P < 0.05). CONCLUSIONS VSL#3 decreases bacterial translocation, the pro-inflammatory state and ileal oxidative damage and increases ileal occludin expression in rats with experimental cirrhosis.

Abstract
Background It is difficult to diagnose spontaneous bacterial peritonitis (SBP) early in decompensated liver cirrhotic ascites patients (DCPs). The aim of the study was to measure serum procalcitonin (PCT) levels and peripheral blood leukocyte/platelet (WBC/PLT) ratios to obtain an early diagnostic indication of SBP in DCPs. Methods Our cohort of 129 patients included 112 DCPs (94 of whom had infections) and 17 cases with compensated cirrhosis as controls. Bacterial cultures, ascitic fluid (AF) leukocyte and peripheral WBC/PLT counts, and serum PCT measurements at admission were carried out prior to the use of antibiotics. Receiver operating characteristic (ROC) curves were generated to test the accuracies and cut-off values for different inflammatory markers. Results Among the 94 infected patients, 66 tested positive by bacterial culture, for which the positivity of blood, ascites and other secretions were 25.8%, 30.3% and 43.9%, respectively. Lung infection, SBP and unknown sites of infection accounted for 8.5%, 64.9% and 26.6% of the cases, respectively. Serum PCT levels (3.02 ± 3.30 ng/mL) in DCPs with infections were significantly higher than those in control patients (0.15 ± 0.08 ng/mL); p < 0.05. We used PCT ≥0.5 ng/mL as a cut-off value to diagnose infections, for which the sensitivity and specificity was 92.5% and 77.1%. The area under the curve (AUC) was 0.89 (95% confidence interval: 0.84–0.91). The sensitivity and specificity were 62.8% and 94.2% for the diagnosis of infections, and were 68.8% and 94.2% for the diagnosis of SBP in DCPs when PCT ≥2 ng/mL was used as a cut-off value. For the combined PCT and WBC/PLT measurements, the sensitivity was 76.8% and 83.6% for the diagnosis of infections or SBP in DCPs, respectively. Conclusion Serum PCT levels alone or in combination with WBC/PLT measurements seem to provide a satisfactory early diagnostic biomarker in DCPs with infections, especially for patients with SBP.

Abstract
BACKGROUND & AIMS Population-based data on the occurrence of healthcare-associated (HCA) and hospital-acquired (HA) bacterial infections in cirrhosis, their predictors, and their impact on outcome are limited. METHODS All patients with incident cirrhosis in 2001-2010 residing in an area of 600,000 inhabitants were retrospectively identified. All serious bacterial infections (resulting in or occurring during an inpatient hospital episode) during this period were registered. Acquisition type, site of infection, occurrence of infection-related acute-on-chronic liver failure (ACLF), acute kidney injury (AKI) and bacterial resistance were analysed. Patients were followed longitudinally until death, transplant or end of 2011. RESULTS A total of 398 serious infections occurred in 241/633 (38%) patients. Forty-seven per cent were HCA and 21% HA. Proton pump inhibitor (PPI) use was more common in HA (80%) vs. HCA (64%) vs. community-acquired (44%) infections (P < 0.001). In regression analysis, decompensated status, use of antibiotics and PPIs at infection diagnosis were independent predictors of HCA/HA infections (P < 0.05). After adjustment for confounders, HCA/HA infections were significantly related to infection-related ACLF (P < 0.05), but not severe sepsis, AKI or infection-related mortality (P > 0.05). Antibiotic-resistant infections were more frequent among HA (17%) than HCA (6%) or community-acquired (8%) infections (P < 0.05). Antibiotic-resistant HCA/HA infections were independently related to severe sepsis (P < 0.05). CONCLUSIONS In a population-based cirrhotic cohort, two-thirds of serious bacterial infections were HCA or HA. Decompensated liver disease, antibiotics and PPIs were predictors of serious HCA/HA infections, which were associated with the development of ACLF. Antibiotic resistance was frequent, especially in HA infections, and contributed to risk of severe sepsis.

Abstract
Gut microbiota plays an important role in cirrhosis. The liver is constantly challenged with commensal bacteria and their products arriving through the portal vein in the so-called gut-liver axis. Bacterial translocation from the intestinal lumen through the intestinal wall and to mesenteric lymph nodes is facilitated by intestinal bacterial overgrowth, impairment in the permeability of the intestinal mucosal barrier, and deficiencies in local host immune defences. Deranged clearance of endogenous bacteria from portal and systemic circulation turns the gut into the major source of bacterial-related complications. Liver function may therefore be affected by alterations in the composition of the intestinal microbiota and a role for commensal flora has been evidenced in the pathogenesis of several complications arising in end-stage liver disease such as hepatic encephalopathy, splanchnic arterial vasodilatation and spontaneous bacterial peritonitis. The use of antibiotics is the main therapeutic pipeline in the management of these bacteria-related complications. However, other strategies aimed at preserving intestinal homeostasis through the use of pre-, pro- or symbiotic formulations are being studied in the last years. In this review, the role of intestinal microbiota in the development of the most frequent complications arising in cirrhosis and the different clinical and experimental studies conducted to prevent or improve these complications by modifying the gut microbiota composition are summarized.

Abstract
Spontaneous bacterial peritonitis (SBP) is the most typical infection observed in cirrhosis patients. SBP is responsible for an in-hospital mortality rate of approximately 32%. Recently, pattern changes in the bacterial flora of cirrhosis patients have been observed, and an increase in the prevalence of infections caused by multi-resistant bacteria has been noted. The wide-scale use of quinolones in the prophylaxis of SBP has promoted flora modifications and resulted in the development of bacterial resistance. The efficacy of traditionally recommended therapy has been low in nosocomial infections (up to 40%), and multi-resistance has been observed in up to 22% of isolated germs in nosocomial SBP. For this reason, the use of a broad empirical spectrum antibiotic has been suggested in these situations. The distinction between community-acquired infectious episodes, healthcare-associated infections, or nosocomial infections, and the identification of risk factors for multi-resistant germs can aid in the decision-making process regarding the empirical choice of antibiotic therapy. Broad-spectrum antimicrobial agents, such as carbapenems with or without glycopeptides or piperacillin-tazobactam, should be considered for the initial treatment not only of nosocomial infections but also of healthcare-associated infections when the risk factors or severity signs for multi-resistant bacteria are apparent. The use of cephalosporins should be restricted to community-acquired infections.

Abstract
The Model for End-Stage Liver Disease (MELD) has been the single best predictor of outcome of the progression of cirrhosis. Acute-on-chronic liver failure (ACLF) has been proposed as an alternative path in the natural history of cirrhosis. ACLF occurs in patients with chronic liver disease and is characterized by a precipitating event, resulting in acute deterioration in liver function, multiorgan system failure, and high short-term mortality. In this review, the natural course of patients with ACLF, especially as it relates to management of cirrhotic patients on the transplant waiting list, and its impact on liver transplantation outcomes are defined.

Abstract
BACKGROUND & AIMS Bloodstream infections (BSIs) in cirrhotic patients are 10-fold more common than in non-cirrhotic patients and increasingly caused by resistant pathogens. We examined 162 BSI episodes in cirrhotic patients to describe the etiology and risk factors for 30-day mortality. METHODS We retrospectively analyzed all consecutive BSIs in patients with liver cirrhosis at our 1350-bed teaching hospital (January 2008 to June 2012). Cox-proportional hazard regression was used to analyze the impact of disease and treatment-related variables on the crude 30-day mortality. RESULTS BSI episodes were identified in 162 patients, including 29 mixed infections. Most of episodes were classified as hospital acquired or healthcare associated (93%). Gram-negative bacteria (GNB), Gram-positive bacteria and Candida spp. caused 64%, 38%, and 10% of episodes, respectively. GNB were classified as multi-drug resistant (MDR) and extensively drug resistant (XDR) in 25% and 21% of cases, respectively. The overall crude 30-day mortality rate was 29%. Four risk factors were independently associated with 30-day crude mortality: worsening of MELD score from baseline (the last MELD score available in the 2 weeks prior BSI) to that at BSI onset (HR 1.11 per point increase, 95% CI 1.07-1.15, p<0.0001), spontaneous bacterial peritonitis as BSI source (HR 4.42, 2.04-9.54, p=0.002), sepsis grading (HR 2.18, 1.39-3.43, p=0.0007), and inappropriate antibiotic therapy within 24h from blood cultures (HR 2.82, 1.50-5.41, p=0.002). CONCLUSION An increasing proportion of BSIs in cirrhotic patients are caused by resistant GNB and Candida spp. Accurate evaluation of risk factors for mortality may improve early appropriate therapeutic management.

Abstract
BACKGROUND & AIMS Asymptomatic bacteriuria (ASB) is a risk factor for urinary tract infections (UTIs) in many patients without liver disease. It remains unclear whether a diagnosis of ASB in an outpatient with cirrhosis could be utilized to predict the subsequent development of a UTI. We undertook this study to determine the prevalence and incidence of ASB in an outpatient population and its association with UTI. METHODS We prospectively evaluated 108 adult outpatients with cirrhosis over a 6-month period. Monthly midstream urines (MSU) were performed to detect the occurrence of UTI and ASB (culture of ≥10(8) CFU/L of a urinary pathogen in the absence of UTI symptoms). RESULTS Of 108 patients enrolled, 99 completed at least one MSU, for a total of 489 MSUs. Total follow-up was 44 person-years. The incidences of ASB and UTI were 181 and 250 per 1000 person-years, respectively. The prevalences of ASB and UTI on the first MSU were 5 and 1%, respectively. In total, 8% of patients developed an episode of ASB and 11% developed a UTI during the study period. Univariate predictors of UTI were female gender, primary biliary cirrhosis, number of previous UTIs and preceding ASB. Preceding ASB was the only independent predictor of UTI on multivariate analysis, with an odds ratio of 6.2 (1.1-34.3), P = 0.04. CONCLUSIONS Cirrhotic patients have higher rates of ASB and UTI than reported in the general population. ASB is an independent predictor of UTI. Further studies are necessary to determine whether routine screening and antimicrobial treatment of ASB is warranted.

Abstract
BACKGROUND AND AIMS Infections are a common and serious complication among patients with cirrhosis. We assessed the epidemiology, risk factors, and clinical consequences of bacterial infections in cirrhotic patients. METHODS In this multicenter prospective study, all patients with cirrhosis of liver with different infections were analyzed. Infections were classified as community-acquired (CA), healthcare-associated (HCA), or hospital-acquired (HA). Site of infection and characteristics of bacteria were recorded; effect on liver function and 30-day survival were evaluated. RESULTS One hundred and six out of 420 (25 %) patients with cirrhosis of liver had infection. Infection rate among indoor patients was 37.5 % (92/245) and among outdoor patients was 8 % (14/175). Out of 106 patients, CA, HCA, and HA were seen in 19.8 %, 50 %, and 30.2 %, respectively. Spontaneous bacterial peritonitis (31.1 %), urinary tract infections (22.6 %), and pneumonia and cellulitis (11.3 % each) were common infections. Gram-negative bacteria (54 %) were more common than Gram-positive cocci (46 %). Multidrug resistant (MDR) organisms were seen in 41.7 % of patients. Most of the MDR organisms were seen in HCA and HA patients. The degree of liver impairment was significantly more severe in patients with infection. Independent predictor of infection was high Child-Turcott-Pugh (CTP) class (p = 0.006, Child B vs. A (odds ratio (OR) 3.04 95 % CI = 1.63 to 5.68) and Child C vs. A (OR 4.17 95 % CI = 2.12 to 8.19). Overall in-hospital mortality was 7.6 %. Patients with infection had increased mortality at 30-day follow up compared to those without infection (23.5 % vs. 2.2 %; p<0.001). CONCLUSIONS Infections are one of the important causes of morbidity and mortality in patients with cirrhosis of liver. The most frequent infections are HCA and HA. Infection predisposes to deterioration of liver function and increases mortality. Cirrhotic patients should be monitored closely for infections especially those with Child class B and C.

Abstract
UNLABELLED Infections worsen survival in cirrhosis; however, simple predictors of survival in infection-related acute-on-chronic liver failure (I-ACLF) derived from multicenter studies are required in order to improve prognostication and resource allocation. Using the North American Consortium for Study of End-stage Liver Disease (NACSELD) database, data from 18 centers were collected for survival analysis of prospectively enrolled cirrhosis patients hospitalized with an infection. We defined organ failures as 1) shock, 2) grade III/IV hepatic encephalopathy (HE), 3) need for dialysis and mechanical ventilation. Determinants of survival with these organ failures were analyzed. In all, 507 patients were included (55 years, 52% hepatitis C virus [HCV], 15.8% nosocomial infection, 96% Child score ≥ 7) and 30-day evaluations were available in 453 patients. Urinary tract infection (UTI) (28.5%), and spontaneous bacterial peritonitis (SBP) (22.5%) were the most prevalent infections. During hospitalization, 55.7% developed HE, 17.6% shock, 15.1% required renal replacement, and 15.8% needed ventilation; 23% died within 30 days and 21.6% developed second infections. Admitted patients developed none (38.4%), one (37.3%), two (10.4%), three (10%), or four (4%) organ failures. The 30-day survival worsened with a higher number of extrahepatic organ failures, none (92%), one (72.6%), two (51.3%), three (36%), and all four (23%). I-ACLF was defined as ≥ 2 organ failures given the significant change in survival probability associated at this cutoff. Baseline independent predictors for development of ACLF were nosocomial infections, Model for Endstage Liver Disease (MELD) score, low mean arterial pressure (MAP), and non-SBP infections. Independent predictors of poor 30-day survival were I-ACLF, second infections, and admission values of high MELD, low MAP, high white blood count, and low albumin. CONCLUSION Using multicenter study data in hospitalized decompensated infected cirrhosis patients, I-ACLF defined by the presence of two or more organ failures using simple definitions is predictive of poor survival.

Abstract
Spontaneous bacterial peritonitis (SBP) in liver transplantation (LT) recipients who progress to cirrhosis has received little attention. We investigated the adequacy of empirical treatment with third-generation cephalosporins for SBP in this population and the impact of transplantation on the evolution of the infection. We performed a cohort study with 138 SBP episodes: 19 in LT patients and 119 in non-LT patients. The etiology of SBP was identified for 73.7% of the episodes in LT patients and for 38.7% of the episodes in non-LT patients (P = 0.004). The main microorganisms in recipients were Escherichia coli (35.7%) and Streptococcus pneumoniae (21.4%). The etiologies did not differ in non-LT patients. The cephalosporin sensitivity was similar in the 2 groups (85.7% versus 78.4%, P = 0.7). LT recipients developed renal failure (57.9% versus 25.2%, P = 0.004) and encephalopathy (42.1% versus 22%, P = 0.08) more often than non-LT patients, and the mortality rates during episodes (52.6% versus 13.4%, P < 0.001) and at 6 months (70.6% versus 34.7%, P = 0.005) were higher. According to a multivariate analysis, the mortality-associated risk factors at diagnosis were a Model for End-Stage Liver Disease (MELD) score > 18 odds ratio (OR) = 6.1 and being an LT recipient (OR = 4.45). At 6 months, the risk factors for mortality were a MELD score > 18 (OR = 3.08), being an LT recipient (OR = 3.47), a known etiology (OR = 2.08), and the presence of hepatocellular carcinoma (OR = 3.73).

Abstract
BACKGROUND Data on bacterial infections in hospitalised patients in the US with cirrhosis are derived largely from single centre data. Countrywide data in this population are lacking. AIM To assess prevalence of infections among hospitalised patients in the US and examine their impact on in-hospital mortality and health care resources utilisation. METHODS Nationwide Inpatient Sample (1998-2007) was queried for hospitalisations with cirrhosis and examined for infections including spontaneous bacterial peritonitis (SBP), urinary tract infection (UTI), skin and soft tissue infections, pneumonia and Clostridium difficile infections (CDI). In-hospital mortality, length of stay (LOS) and total charges were analysed. RESULTS Of 742,391 admissions with cirrhosis, 168,654 (23%) had discharge diagnosis of any infection. Between 1998 and 2007, there was a trend towards increasing prevalence of infections (21-25%). Higher rates of infection were associated with ascites (22-25%) and renal insufficiency (RI) (38-43%). Infection with RI increased from 13% in 1998 to 27% in 2007. UTI was the most common infection (9-12%) followed by subcutaneous tissue infections (5-6%) and SBP (2-3%, around 12% in patients with ascites). Infection rate was similar among teaching and nonteaching hospitals with CDI and SBP being more common in teaching hospitals. In-hospital mortality was about 5%, over fivefold higher in infected cirrhotics, and associated with higher LOS and charges. Sepsis (38-42%), pneumonia (23-30%), SBP (16-23%) and CDI (11-16%) contributed most to in-hospital mortality. CONCLUSIONS The prevalence of infections among hospitalised patients with cirrhosis in the US is increasing and is associated with in-hospital mortality, renal insufficiency and costs.

Abstract
Despite major advances in the knowledge and management of liver diseases achieved in recent decades, decompensation of cirrhosis still carries a high burden of morbidity and mortality. Bacterial infections are one of the main causes of decompensation. It is very important for clinical management to be aware of the population with the highest risk of poor outcome. This review deals with the new determinants of prognosis in patients with cirrhosis and bacterial infections reported recently. Emergence of multiresistant bacteria has led to an increasing failure rate of the standard empirical antibiotic therapy recommended by international guidelines. Moreover, it has been recently reported that endothelial dysfunction is associated with the degree of liver dysfunction and, in infected patients, with the degree of sepsis. It has also been reported that relative adrenal insufficiency is frequent in the non-critically ill cirrhotic population and it is associated with a higher risk of developing infection, severe sepsis, hepatorenal syndrome and death. We advise a change in the standard empirical antibiotic therapy in patients with high risk for multiresistant infections and also to take into account endothelial and adrenal dysfunction in prognostic models in hospitalized patients with decompensated cirrhosis.
