Abstract
INTRODUCTION It is unclear if Nosocomial Spontaneous Bacteria Peritonitis (NSBP) is associated with higher mortality compared with community acquired spontaneous bacterial peritonitis. METHODS Database search from inception to May 2022 was conducted. The databases included MEDLINE, EMBASE, Cochrane registry of Controlled Trials, Cochrane Database of Systematic Reviews, and Scopus. Inclusion criteria were as follows: adult patients, age >18 years, with a diagnosis of NSBP. Pooled estimates of mortality were calculated following the restricted maximum likelihood method. The mortality rate between NSBP and CA-SBP was reported as odds ratio (OR) and 95% confidence interval (CI). Data synthesis was obtained using random effects meta-analysis. Heterogeneity was reported as I2. RESULTS A total of 482 unique titles were screened. Twenty-two articles were included. A total of 2,145 patients with NSBP were included. Patients were followed for a median of 90 days. The pooled mortality rate of NSBP was 52.51% (95% CI 42.77-62.06%; I2 83.72%). Seven studies compared the mortality outcome of patients with NSBP and CA-SBP. NSBP was significantly associated with a higher rate of mortality (OR 2.78, 95% CI 1.87-4.11; I2 36.00%). CONCLUSION NSBP was associated with higher mortality rate compared to CA-SBP, which could be due to a higher rate of resistance organisms.

Abstract
INTRODUCTION Spontaneous bacterial peritonitis (SBP) is a common complication in decompensated liver cirrhosis with ascitic fluid polymorphonuclear cell count > 250/mm3. Community acquired SBP (CA-SBP) occurs within the first 48 hours after hospital admission. Nosocomial SBP (N-SBP) occurs 48-72 hours after hospitalization. Healthcare associated SBP (HA-SBP) occurs in patients hospitalized in the preceding 90 days to months. We aim to evaluate mortality and resistance patterns to third generation cephalosporin among the three types. METHODS Multiple databases were systematically searched from inception through August 1st, 2022. Both pairwise (direct) and network (direct + indirect) meta-analysis was performed using a random effects model and DerSimonian Laird approach. Relative Risk (RR) with 95% confidence intervals (CI) were calculated. Network meta-analysis was conducted using frequentist approach. RESULTS A total of 14 studies with a total of 2302 SBP episodes were evaluated. On direct meta-analysis, mortality rate was higher in N-SBP compared to HA-SBP (RR 1.84, CI 1.43- 2.37) and CA-SBP (RR 1.69, CI 1.4-1.98), but not significantly different between HA-SBP and CA-SBP (RR=1.40, CI=0.71-2.76). Resistance to third generation cephalosporins was significantly higher in N-SBP compared to HA-SBP (RR=2.02, CI 1.26-3.22) and CA-SBP (RR=3.96, CI=2.50-3.60) as well as in HA-SBP compared to CA-SBP (RR=2.25, CI=1.33-3.81). CONCLUSIONS Our network meta-analysis shows increased mortality and antibiotic resistance with nosocomial SBP. We recommend clearly identifying such patients to manage accordingly as well as developing guidelines geared towards nosocomial infections to be able to optimally steer resistance patterns and reduce mortality.

Extended Spectrum β-Lactamase-Producing Enterobacterales of Shrimp and Salmon Available for Purchase by Consumers in Canada-A Risk Profile Using the Codex Framework. Antibiotics (Basel) 2023; 12:1412. [PMID: 37760708 PMCID: PMC10525137 DOI: 10.3390/antibiotics12091412] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/02/2023] [Revised: 08/24/2023] [Accepted: 09/02/2023] [Indexed: 09/29/2023] Open
Abstract
The extended-spectrum β-lactamase (ESBL)-producing Enterobacterales (ESBL-EB) encompass several important human pathogens and are found on the World Health Organization (WHO) priority pathogens list of antibiotic-resistant bacteria. They are a group of organisms which demonstrate resistance to third-generation cephalosporins (3GC) and their presence has been documented worldwide, including in aquaculture and the aquatic environment. This risk profile was developed following the Codex Guidelines for Risk Analysis of Foodborne Antimicrobial Resistance with the objectives of describing the current state of knowledge of ESBL-EB in relation to retail shrimp and salmon available to consumers in Canada, the primary aquacultured species consumed in Canada. The risk profile found that Enterobacterales and ESBL-EB have been found in multiple aquatic environments, as well as multiple host species and production levels. Although the information available did not permit the conclusion as to whether there is a human health risk related to ESBLs in Enterobacterales in salmon and shrimp available for consumption by Canadians, ESBL-EB in imported seafood available at the retail level in Canada have been found. Surveillance activities to detect ESBL-EB in seafood are needed; salmon and shrimp could be used in initial surveillance activities, representing domestic and imported products.

Abstract
A male in his mid-60s with chronic kidney disease, ischemic cardiomyopathy, and nonalcoholic cirrhosis due to congestive hepatopathy presented with fever and abdominal pain for two weeks. He underwent diagnostic paracentesis, which noted an ascitic neutrophil count over 7000/mm3. Gram stain of the ascitic fluid showed Gram-positive cocci. He was diagnosed with spontaneous bacterial peritonitis (SBP) and was started on ceftriaxone. Ascites cultures grew Listeria monocytogenes and antibiotics were changed to ampicillin. He received one week of ampicillin while inpatient and seven weeks of oral amoxicillin, at which point his ascitic neutrophil count was less than 250/mm3. He was continued on suppressive amoxicillin for an additional 14 weeks with no recurrence in over a year after the discontinuation of amoxicillin. Though uncommon, L. monocytogenes should be considered a pathogen causing SBP. Focal listerial infections can be treated with penicillins alone while invasive disease may require the addition of aminoglycosides.

Abstract
OBJECTIVE Third-generation cephalosporins (3rd GCs) have recently become controversial as the first-line strategy for empirical spontaneous bacterial peritonitis (SBP) treatment. This study aimed to identify SBP treatment efficacy predictors of 3rd GCs. METHODS In this retrospective cohort study, 279 cirrhosis patients with SBP who received 3rd GC monotherapy for initial empirical treatment from 2013 to 2019 were included. Nonresponse was defined as a decreased ascites polymorphonuclear (PMN) count < 25% from baseline after 48 hours of antibacterial treatment. Multivariate regression analysis was used to identify efficacy predictors of 3rd GCs in treating SBP. Kaplan-Meier analysis was used to evaluate survival data. RESULTS The nonresponder group included 120 patients with no response, and the responder group included 159 patients with responses. The response rate to 3rd GCs was 57.0% among all patients. The common pathogens were Escherichia coli (40.6%), Staphylococcus (15.6%), Klebsiella pneumonia (12.5%), and Streptococcus (12.5%) in 32 ascites culture isolates. Nosocomial SBP (NSBP) (odds ratio [OR]: 2.371, 95% confidence interval [CI]: 1.323-4.249, P = .004), pneumonia (OR: 11.561, 95% CI: 1.876-71.257, P = .008), recurrent SBP (OR: 3.386, 95% CI: 1.804-6.357, P < .001), platelet count (≥113.5 × 109/L) (OR: 3.515, 95% CI: 1.973-6.263, P < .001), and ascites PMN count (≤0.760 × 109/L) (OR: 4.967, 95% CI: 2.553-9.663, P < .001) were independent predictors of nonresponse to 3rd GCs against SBP. Survival plot analysis at 30 days showed worse survival for the nonresponders (P = .003). CONCLUSION NSBP, pneumonia, recurrent SBP, increased platelet count, and lower ascites PMN count were independent predictors of nonresponse to 3rd GC in treating SBP. Nonresponse to initial antibiotic treatment was associated with worse survival.

Rifaximin Modulates the Gut Microbiota to Prevent Hepatic Encephalopathy in Liver Cirrhosis Without Impacting the Resistome. Front Cell Infect Microbiol 2022; 11:761192. [PMID: 35118004 PMCID: PMC8804384 DOI: 10.3389/fcimb.2021.761192] [Citation(s) in RCA: 14] [Impact Index Per Article: 7.0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/18/2021] [Accepted: 12/22/2021] [Indexed: 12/21/2022] Open
Abstract
The gut microbiota has an important role in the pathogenesis of hepatic encephalopathy(HE). Rifaximin, an intestinal non-absorbable antibacterial agent, is effective in the treatment of HE. However, whether long-term prophylactic use induces antibacterial resistance and its mechanism for treating HE remains unclear. This prospective study assessed the impact of 12 weeks rifaximin administration on the gut microbiota and resistome in cirrhotic patients. Fecal sampling was conducted 1 day before the first rifaximin administration and at Weeks 1, 2, 4, 6, 8, 10, 12 of the study. Thirty cirrhotic patients who were in remission from recurrent HE was enrolled to receive rifaximin (400mg TID for 12 weeks). Rifaximin improved hyperammonemia and cognitive function in the 21 patients who completed rifaximin treatment. The dynamic observations showed the gut microbiota diversity, composition and the number of resistance genes, plasmids, insertion sequences did not change significantly during the period(P>0.05). Metabolic pathways such as aromatic amino acids, tryptophan synthesis, urea cycle, and LPS synthesis reduced. No new antimicrobial resistance genes was emergenced. However, the number of aminoglycosides, rifamycin and phenolic resistance genes increased, whereas tetracycline, fosfomycin and cephamycin decreased (P<0.05). Changes in the abundance of E. coli, K. pneumoniae, and B. longum strains correlated with changes of resistance genes. Prophylactic use of rifaximin for 12 weeks improved hyperammonemia and neurophysiological function, maintained gut microbiota diversity, composition and did not change the overall resistome. Rifaximin altered expression of HE-related metabolic pathways. All of these effects could play a key role in preventing HE. Clinical Trial Registration: ChiCTR1900022234 (registered at the Chinese Clinical Trial Registry).

Abstract
Background and Aims: Spontaneous bacterial peritonitis (SBP) is a common and potentially fatal complication of liver cirrhosis. This study aims to analyze the prevalence of SBP among liver cirrhotic patients according to geographical location and income level, and risk factors and outcomes of SBP. Methods: A systematic search for articles describing prevalence, risk factors and outcomes of SBP was conducted. A single-arm meta-analysis was performed using generalized linear mix model (GLMM) with Clopper-Pearson intervals. Results: Ninety-Nine articles, comprising a total of 5,861,142 individuals with cirrhosis were included. Pooled prevalence of SBP was found to be 17.12% globally (CI: 13.63-21.30%), highest in Africa (68.20%; CI: 12.17-97.08%), and lowest in North America (10.81%; CI: 5.32-20.73%). Prevalence of community-acquired SBP was 6.05% (CI: 4.32-8.40%), and 11.11% (CI: 5.84-20.11%,) for healthcare-associated SBP. Antibiotic-resistant microorganisms were found in 11.77% (CI: 7.63-17.73%) of SBP patients. Of which, methicillin-resistant Staphylococcus aureus was most common (6.23%; CI: 3.83-9.97%), followed by extended-spectrum beta-lactamase producing organisms (6.19%; CI: 3.32-11.26%), and lastly vancomycin-resistant enterococci (1.91%; CI: 0.41-8.46%). Subgroup analysis comparing prevalence, antibiotic resistance, and outcomes between income groups was conducted to explore a link between socioeconomic status and SBP, which revealed decreased risk of SBP and negative outcomes in high-income countries. Conclusion: SBP remains a frequent complication of liver cirrhosis worldwide. The drawn link between income level and SBP in liver cirrhosis may enable further insight on actions necessary to tackle the disease on a global scale.

GE-PORTUGUESE JOURNAL OF GASTROENTEROLOGY 2021; 29:256-266. [PMID: 35979243 PMCID: PMC9274822 DOI: 10.1159/000518585] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Subscribe] [Scholar Register] [Received: 02/18/2021] [Accepted: 07/08/2021] [Indexed: 11/19/2022]
Abstract
<b><i>Introduction:</i></b> Over the last decade, a shift in the spontaneous bacterial peritonitis (SBP) microbial pattern toward an increasing incidence of gram-positive and multidrug-resistant (MDR) bacteria has been reported. Systematic surveillance of the local microbiological scenario and antibiotic resistance is crucial to SBP treatment success. The main objective of this study was to evaluate the microbiological profile and bacterial resistance of SBP pathogens in a Portuguese cohort to allow selection of the most appropriate empirical antibiotics. <b><i>Methods:</i></b> This is a single-center retrospective study including 63 adult cirrhotic patients with culture-positive SBP. Patients were identified using a hospital general diagnostic database and searching for all SBP events (neutrophil count in ascitic fluid ≥250/mm<sup>3</sup>) from January 1, 2012, to December 31, 2017. Patients were excluded if they had culture-negative SBP, secondary peritonitis, peritoneal dialysis, a liver transplant, or immunodeficiency. The site of SBP acquisition was classified as nosocomial if it was diagnosed 48 h or longer after hospitalization or as nonnosocomial if it was diagnosed within the first 48 h. MDR bacteria were those with an acquired resistance to at least 1 agent in 3 or more antimicrobial categories. All statistical analyses were carried out using IBM SPSS Statistics software version 22 (IBM, New York, USA). <b><i>Results:</i></b> The study cohort comprised 53 (84.1%) men. The mean age of the patients was 60.6 ± 11.2 years. Alcohol was the most common etiology (88.9%) and most patients had advanced liver cirrhosis (87.1%, Child C). Gram-negative bacteria were slightly more frequent than gram-positive bacteria (56.9 vs. 43.1%). <i>Escherichia coli</i> was the most common pathogen (33.8%). Nineteen (31.7%) bacteria were classified as MDR. Resistance to third-generation cephalosporins, quinolones, piperacillin-tazobactam, and carbapenems was found in 31.7, 35, 26.7, and 18.3% of the cases, respectively. The rates of gram-positive bacteria were similar between nosocomial and nonnosocomial episodes (45 vs. 42.2%; <i>p</i> = 0.835). MDR bacteria were more common in the nosocomial group (50 vs. 23.8%; <i>p</i> = 0.046). Resistance to third-generation cephalosporins (50 vs. 23.8%; <i>p</i> = 0.046), piperacillin-tazobactam (44.4 vs. 19.1%; <i>p</i> = 0.041), and carbapenems (33.3 vs. 11.9%; <i>p</i> = 0.049) occurred more frequently in nosocomial episodes. Resistance to first-line antibiotic occurred in 29.3% of the patients, being more common in the nosocomial group (44.4 vs. 22.5%; <i>p</i> = 0.089). <b><i>Conclusion:</i></b> Although gram-negative bacteria remain the most common causative microorganisms, our results emphasize the shift in SBP microbiological etiology, as almost half of the isolated microorganisms were gram positive. The emergence of bacteria resistant to traditionally recommended empirical antibiotics underlines the importance of basing this choice on local flora and antibiotic susceptibility data, allowing a more rational and successful use of antibiotics.

Causes of Death and Survival in Alcoholic Cirrhosis Patients Undergoing Liver Transplantation: Influence of the Patient's Clinical Variables and Transplant Outcome Complications. Diagnostics (Basel) 2021; 11:diagnostics11060968. [PMID: 34072173 PMCID: PMC8227029 DOI: 10.3390/diagnostics11060968] [Citation(s) in RCA: 4] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/18/2021] [Revised: 05/20/2021] [Accepted: 05/24/2021] [Indexed: 11/17/2022] Open
Abstract
Background. Clinical and molecular mechanisms involved in the cause and time of death of alcoholic cirrhosis (AC) patients undergoing liver transplantation (LT) are not entirely understood. In sudden death cases, judicial autopsy practice is mandatory for determining the cause and circumstances of death. The medico-legal autopsy data are essential for helping health authorities to guide future public health activities, assess the effectiveness of health systems, and adopt the necessary preventive measures to improve and adapt the treatments in order to increase these patients’ survival. Objective. Our study aimed to determine the different clinical and sociodemographic causes that influence the different causes of death and the short- and long-term survival of AC patients undergoing liver transplantation. Methods. A total of 122 deceased AC patients undergoing LT were analyzed at different times post-transplantation. The main pre- and post-transplant complications were analyzed in relation to the cause of death and the patient’s survival, as well as the causes and time at which the patient’s death occurred. Results. A total of 53.3% of non-sudden death was observed. A large number of the deaths of AC patients undergoing transplantation were due to non-sudden death, sepsis, and graft failure (GF), the main causes of death in the sample being similar in both sexes. In non-sudden deaths, there were no significant differences between the death rates either related or not related to the liver transplant. Sepsis was the main cause, with the highest percentage (21.3%) of mortality, followed by GF (18.9%) and multiorgan failure (15.6%) at ten years. Furthermore, our results showed how pre-transplant clinical complications, such as viral infections and encephalopathy, influence the age at which multiorgan failure occurs in the transplanted patient. Conclusion. Multiorgan failure is the leading cause of sudden death, with higher mortality during the first year after transplantation, followed by sepsis and GF. Our results show the vulnerability of AC patients, both in the hospital period after the transplant and outside.

Abstract
INTRODUCTION Paraphenylenediamine (PPDA) is a chemical with strong sensitizing properties used for dyeing of hair and textiles. Paraphenylenediamine can cross-react, resulting in allergy to other related compounds. The prevalence of PPDA sensitization varies widely. The objectives were to assess the frequency of positive patch test reactions to PPDA and related chemicals among patients with allergic contact dermatitis (ACD) and to analyze them regarding their clinical pattern, occupation and cross-reactions. MATERIAL AND METHODS The sociodemographic and clinical data of patients with positive patch tests to PPDA, N-isopropyl-N-phenyl-4-phenylenediamine (IPPD), ethylenediamine (EDA), triethylenetetramine (TETA) and toluene-2,5-diamine (TDA) were analyzed. The frequency, strength and cross-reactions with other chemicals were assessed. RESULTS Of 4087 ACD patients patch-tested between 2006 and 2015, positive reactions to PPDA and other amines were found in 166 (4.1%). The occupational character of PPDA allergy was established in 34.3% of patients. Personal history of atopy was reported by 36.7% of patients. In 98% of those examined, allergy presented as ACD, most frequently affecting hands. Hypersensitivity to PPDA was diagnosed in 77.1%, to IPPD in 20.5%, to TDA in 6%, to TETA in 1.2%, and to EDA in 0.6% of cases. The patients with an extremely strong PPDA reaction significantly more frequently showed reactions to other para group chemicals, especially to benzocaine. CONCLUSIONS Paraphenylenediamine was a major cause of contact allergy of diverse clinical picture more often affecting women, especially with atopy. Every fifth PPDA-allergic person exhibited hypersensitivity to other related compounds. Strong reactions to PPDA increased the risk of cross-reactions.

Abstract
INTRODUCTION The Child-Pugh and model for end-stage liver disease (MELD) scores are widely used to predict the outcomes of liver transplant (LT). Both have similar prognostic values in most cases, although their benefits might differ in some specific conditions. The aim of our study was to analyze the influence of pre-transplant ascites and encephalopathy in post-transplant liver rejection development and survival in alcohol cirrhosis (AC) patients undergoing LT to determine the usefulness of the Child-Pugh score for the assessment of prognosis in such patients. MATERIAL AND METHODS Two hundred and eighty-one AC patients, classified according to viral infections and pre-transplant complications, were analyzed. Acute (AR) and chronic (CR) liver rejections and Child-Pugh, MELD and albumin-bilirubin (ALBI) scores were studied in all cases. RESULTS Similar AC rejection percentages were observed in ascites or encephalopathy groups (18.5% and 16.5%, p = 0.735), although a higher but not statistically significant AC rate was observed in patients with grade III ascites (p = 0.777) and with grade II encephalopathy (p = 0.089). Chronic rejection was only developed by 9.1% of AC patients, regardless of the presence of ascites (6.2%) or encephalopathy (5.5%). The presence of ascites and encephalopathy complications did not seem to influence post-transplant survival. Neither the Child-Pugh nor the ALBI score can be considered the best for predicting patient survival in the short or long term. CONCLUSIONS Ascites and encephalopathy do not seem to influence AC or CR in patient survival, regardless of the presence of viral infections, so in our study neither the Child-Pugh nor ALBI score seems to be the best score to predict the outcomes of these patients.

Current Status and Prospects of Spontaneous Peritonitis in Patients with Cirrhosis. BIOMED RESEARCH INTERNATIONAL 2020; 2020:3743962.

Abstract
Spontaneous bacterial peritonitis (SBP) is a common cirrhotic ascites complication which exacerbates the patient's condition. SBP is caused by gram-negative bacilli and, to a lesser extent, gram-positive cocci. Hospital-acquired infections show higher levels of drug-resistant bacteria. Geographical location influences pathogenic bacteria distribution; therefore, different hospitals in the same country record different bacteria strains. Intestinal changes and a weak immune system in patients with liver cirrhosis lead to bacterial translocation thus causing SBP. Early diagnosis and timely treatment are important in SBP management. When the treatment effect is not effective, other rare pathogens should be explored.

Abstract
OBJECTIVES There are few studies addressing the impact of cephalosporin and quinolone resistance on hospital length of stay and mortality in spontaneous bacterial peritonitis (SBP). We aim to describe the shifting epidemiology of SBP at our institution and its impact on clinical outcomes. METHODS We performed a single-center retrospective cohort study of all cases of SBP from 2005 to 2015 at a transplant center. Cases were identified using hospital billing data. Patient data were confirmed using the electronic medical record. Univariate and multivariate logistic regression and Cox proportional hazards models were used to identify factors that were associated with prolonged hospital length of stay and reduced survival. Culture-positive cases (N = 56) were compared to culture-negative cases (N = 104). Subpopulation analysis of the culture-positive cases compared ceftriaxone-resistant (N = 25) to ceftriaxone-susceptible (N = 31) cases. RESULTS We identified 160 cases of SBP (56 culture positive and 104 culture negative; 21 nosocomial, 79 hospital associated, and 60 community acquired). Forty-five percent (N = 25 total, 13 hospital associated and 6 nosocomial) of bacterial isolates were resistant to ceftriaxone, with 37.5% (N = 21) being gram positive, including 8 methicillin-resistant staphylococcus and 6 vancomycin-resistant enterococcus. Multivariate analysis identified hospital-associated SBP, age, alcoholic cirrhosis, and MELD-Na score as variables associated with worse survival (P < 0.05), with a trend toward worse survival in culture-positive cases (P = 0.123). Only MELD-Na was associated with prolonged length of stay. CONCLUSIONS The burden of resistant pathogens causing SBP is significant, notably in hospital-associated SBP. Culture-positive SBP may represent a higher risk group compared to culture-negative SBP.

Abstract
Introduction: Spontaneous bacterial peritonitis (SBP) is a main infectious complication in end-stage liver disease (ESLD) patients. The increasing trend of bacterial resistance in ESLD patients with SBP has been associated with low treatment efficacy of traditional therapy. Cephalosporin use has been restricted to community-acquired infections and in areas/health care settings with low rates of multidrug-resistant (MDR) bacteria. To date, several changes are necessary with regard to empiric therapy recommendations in areas/health care settings with high rates of MDR bacteria. Areas covered: An overview of the epidemiology and antimicrobial treatments of SBP caused by Gram-negative bacteria. Expert opinion: Broad-spectrum antibiotics have been recommended as empiric therapy for suspected SBP in areas/health care settings with high rates of MDR bacteria and secondary treatment, with newer antibiotics, for SBP caused by MDR-Gram-negative bacteria (i.e. new beta-lactam/beta-lactamase inhibitor combinations, cefiderocol, plazomicin, and eravacycline) either alone or in combination.

Abstract
Microbial infection is an important cause of acute-on-chronic liver failure (ACLF), which is a syndrome that results in multiple organ dysfunction or failure and is accompanied by an increased short-term risk of mortality. Early detection and treatment of microbial infection can effectively reduce the mortality of patients with ACLF. However, antimicrobial resistance has recently increased due to the increased use of antimicrobial agents. Therefore, it is important to choose appropriate antibiotics and antifungal agents for early prevention or treatment of patients with microbial infection and ACLF to reduce the occurrence of drug resistance and to reduce patient mortality. This review summarizes the current status in the understanding of the epidemiology, pathogenesis, early diagnosis, treatment, and strategies for prevention of microbial infection in patients with ACLF.

Abstract
Background Spontaneous bacterial peritonitis (SBP) is a serious complication and common cause of death in patients with liver cirrhosis. This study was conducted to compare the microbiological characteristics, drug resistance, and treatment outcomes for nosocomial SBP and community-acquired SBP. Methods A retrospective study was performed on 334 patients with culture-positive SBP at Beijing Youan Hospital, China, between January 2012 and December 2016. The medical records for these patients were reviewed, and their clinical and laboratory data were analyzed. Results A total of 155 (46.4%) patients with nosocomial SBP and 179 (53.6%) with community-acquired SBP were included in this study. From the patients’ ascitic fluids, 334 pathogenic strains, including 178 Gram-negative bacterial strains, 138 Gram-positive bacterial strains and 18 other microbial strains were isolated. E. coli was the major pathogen (24.3%), followed by Klebsiella pneumoniae (12.0%) and Enterococcus faecium (10.5%). The proportion of Enterococcus was significantly higher in the patients with nosocomial SBP (6.1% vs. 27.7%, P < 0.001) than in the patients with community-acquired SBP. The main pathogens isolated from the nosocomial infections were significantly more resistant to the first-line recommended drug. Compared with community-acquired SBP, nosocomial SBP had a poorer outcome (36.8% vs. 24.6%; P = 0.016). The independent predictors for 30-day mortality included nosocomial infection, Child-Pugh classification, hepatocellular carcinoma, renal failure and hepatic encephalopathy. Conclusion Gram-negative bacteria were the major pathogens involved in SBP in the cirrhotic patients. The strains isolated from the patients with nosocomial SBP displayed higher drug resistance than those isolated from patients with community-acquired SBP. Compared with community-acquired SBP, nosocomial SBP had a poorer outcome. When choosing drug treatments, the acquisition site of infection and the local epidemiological situation should be taken into account.

Abstract
BACKGROUND & AIMS Antibiotic resistance has been increasingly reported in patients with decompensated cirrhosis in single-center studies. Prospective investigations reporting broad epidemiological data are scarce. We aimed to analyze epidemiological changes in bacterial infections in patients with decompensated cirrhosis. METHODS This was a prospective evaluation of 2 series of patients hospitalized with decompensated cirrhosis. The Canonic series included 1,146 patients from Northern, Southern and Western Europe in 2011. Data on epidemiology, clinical characteristics of bacterial infections, microbiology and empirical antibiotic schedules were assessed. A second series of 883 patients from Eastern, Southern and Western Europe was investigated between 2017-2018. RESULTS A total of 455 patients developed 520 infections (39.7%) in the first series, with spontaneous bacterial peritonitis, urinary tract infections and pneumonia the most frequent infections. Nosocomial episodes predominated in this series. Nearly half of the infections were culture-positive, of which 29.2% were caused by multidrug-resistant organisms (MDROs). MDR strains were more frequently isolated in Northern and Western Europe. Extended-spectrum beta-lactamase-producing Enterobacteriaceae were the most frequent MDROs isolated in this series, although prevalence and type differed markedly among countries and centers. Antibiotic resistance was associated with poor prognosis and failure of antibiotic strategies, based on third-generation cephalosporins or quinolones. Nosocomial infection (odds ratio [OR] 2.74; p < 0.001), intensive care unit admission (OR 2.09; p = 0.02), and recent hospitalization (OR 1.93; p = 0.04) were identified as independent predictors of MDR infection. The prevalence of MDROs in the second series (392 infections/284 patients) was 23%; 38% in culture-positive infections. A mild increase in the rate of carbapenem-resistant Enterobacteriaceae was observed in this series. CONCLUSIONS MDR bacterial infections constitute a prevalent, growing and complex healthcare problem in patients with decompensated cirrhosis and acute-on-chronic liver failure across Europe, negatively impacting on prognosis. Strategies aimed at preventing the spread of antibiotic resistance in cirrhosis should be urgently evaluated. LAY SUMMARY Infections caused by bacteria resistant to the main antibiotic families are prevalent in patients with cirrhosis. This study demonstrates that this healthcare problem is increasing and extends through all European regions. Infections caused by these difficult to treat bacteria resolve less frequently and often cause the death of the patient. The type of resistant bacteria varies markedly among different hospitals.

Abstract
Objective: To determine 3rd generation cephalosporin resistance in patients with community-acquired spontaneous bacterial peritonitis (SBP) using early response assessment. Methods: This prospective quasi-experimental study was carried out at Doctors Hospital & Medical Center from January 2016 to September 2018. Patients with cirrhosis and SBP were included. Third generation cephalosporins i.e. cefotaxime/ceftriaxone were used for treatment of SBP. Response after 48 hours was assessed and decline in ascitic fluid neutrophil count of < 25% of baseline was labelled as cephalosporin resistant. Carbapenem were used as second line treatment. Recovery and discharge or death of patients were primary end points. Results: Male to female ratio in 31 patients of SBP was 1.2/1 (17/14). Hepato-renal syndrome was diagnosed in 11(37.9%) patients. Cefotaxime was used for 16(51.6%) patients whereas ceftriaxone for 15(48.3%) patients. Early response of SBP was noted in 26(83.8%) patients while 5 (16.2%) were non-responders to cephalosporins. SBP resolved in all non-responding patients with i/v carbapenem. In-hospital mortality was 12.9% and had no association with cephalosporin resistance. High bilirubin (p 0.04), deranged INR (p 0.008), low albumin (p 0.04), high Child Pugh (CTP) score (p 0.03) and MELD scores (p 0.009) were associated with in-hospital mortality. Conclusion: Cephalosporin resistance was present in 16.2% of study patients with community-acquired SBP. Mortality in SBP patients is associated with advanced stage of liver disease.

Abstract
BACKGROUND Knowledge about bacterascites is limited and management guidelines are based on small patient series. The purpose of this study was to add further insight into the clinical characteristics, microbiological findings, and prognosis of patients diagnosed with bacterascites. METHODS Retrospective analysis of patients with advanced chronic liver disease diagnosed with bacterascites and SBP between January 2003 and August 2016. RESULTS In this study, 123 patients were included with 142 episodes of bacterascites. The median MELD score was 20 and clinical symptoms of infection were present in 78%. Empiric antibiotic treatment was initiated in 68%. In 26 untreated patients undergoing repeated paracentesis, 42% were diagnosed with either ongoing bacterascites or SBP. The presence of signs or symptoms of infection was not an independent predictor for mortality or spontaneous resolution of infection. The 1-month and 1-year mortality rates of the 123 patients studied, were 32% and 60%, respectively; these results were in line with data pertaining to the prognosis of SBP. CONCLUSIONS Patients with bacterascites and SBP are highly comparable with respect to severity of liver disease and overall prognosis. If left untreated, bacterascites is likely to persist or to evolve to SBP in a significant proportion of patients. The results of this study support current guidelines regarding the treatment of ascitic fluid infection, but could not confirm the prognostic relevance of symptomatic disease at the time of diagnosis. We suggest that the threshold to initiate antibiotic treatment, in particular in cases with severely advanced liver disease, should be low.

Abstract
GOALS The objective of this study was to assess the prevalence and predictors of multidrug resistant organisms (MDRO) in cirrhotic patients with bacteremia at a large tertiary center in the United States. BACKGROUND The epidemiology of bacteremia in patients with liver cirrhosis has not been well studied in the United States. STUDY This case-case control study included 180 adults with liver cirrhosis hospitalized from 2011 to 2015. Case group 1 were patients with bacteremia due to a MDRO (n=30). Case group 2 were patients with bacteremia due to a non-MDRO (n=60). Control group comprised patients without bacteremia (n=90). MDRO was defined as bacteria that was nonsusceptible to ≥1 agent in ≥3 antimicrobial categories. RESULTS Of the 90 bacteremia episodes, 44% were because of gram-positive bacteria, 50% were because of gram-negative bacteria, and 6% were polymicrobial. MDROs caused 30 of 90 (33%) bacteremia episodes, including methicillin-resistant Staphylococcus species [12% (11/90)], fluoroquinolone-resistant Enterobacteriaceae [10% (9/90)], and Enterococcus faecium [3% (3/90)]. Eight percent of Enterobacteriaceae produced extended-spectrum β-lactamases. Four independent predictors of MDROs were identified: nonwhite race [adjusted odds ratio (aOR), 3.35; 95% confidence interval (CI), 1.19-9.38], biliary cirrhosis (aOR, 11.75; 95% CI, 2.08-66.32), blood cultures obtained >48 hours after hospital admission (aOR, 6.02; 95% CI, 1.70-21.40), and recent health care exposure (aOR, 9.81; 95% CI, 2.15-44.88). CONCLUSIONS A significant proportion of bacteremia in cirrhotic patients was due to MDROs at a large US tertiary care center. Local epidemiology data and identification of risk factors associated with MDROs may help with optimal empiric antibiotic selection.

Abstract
OBJECTIVES The epidemiology of spontaneous bacterial peritonitis (SBP) due to ceftriaxone-resistant organisms has not been well studied in the USA. The primary objective of this study was to assess the prevalence and predictors of ceftriaxone-resistant SBP at a large US tertiary-care centre. METHODS This 1:1:4 case-case-control study included 141 adults with liver cirrhosis admitted from November 2011 to March 2016. Case group 1 were patients with SBP with a ceftriaxone-resistant organism (n=21). Case group 2 were patients with SBP with a ceftriaxone-susceptible organism (n=26). The control group were patients without SBP (n=94). Multiple logistic regression analysis was used to identify predictors of ceftriaxone-resistant SBP. RESULTS Fifty isolates were identified from 47 patients with culture-positive SBP (case groups 1 and 2). Of these 50 isolates, 32 (64%) were Gram-negatives [mostly Enterobacteriaceae (91%)], 15 (30%) were Gram-positives and 3 (6%) were Candida spp. The prevalence of ceftriaxone resistance in patients with culture-positive SBP was 45% (21/47). The most common ceftriaxone-resistant organisms were ESBL-producing Enterobacteriaceae (45%). Independent predictors of ceftriaxone-resistant SBP included duration of β-lactam therapy in the past 90days (aOR=1.07, 95% CI 1.01-1.13) and recent invasive gastrointestinal procedure (aOR=12.47, 95% CI 2.74-56.67). CONCLUSIONS The prevalence of ceftriaxone-resistant SBP was significant at a US tertiary centre. Local epidemiological data and identification of risk factors associated with ceftriaxone-resistant SBP, e.g. increased usage of previous β-lactam therapy and invasive gastrointestinal procedure, may help clinicians identify patients requiring alternative empirical antibiotics.

Abstract
Background Accurate estimates of the burden of antimicrobial resistance (AMR) are needed to establish the magnitude of this global threat in terms of both health and cost, and to paramaterise cost-effectiveness evaluations of interventions aiming to tackle the problem. This review aimed to establish the alternative methodologies used in estimating AMR burden in order to appraise the current evidence base. Methods MEDLINE, EMBASE, Scopus, EconLit, PubMed and grey literature were searched. English language studies evaluating the impact of AMR (from any microbe) on patient, payer/provider and economic burden published between January 2013 and December 2015 were included. Independent screening of title/abstracts followed by full texts was performed using pre-specified criteria. A study quality score (from zero to one) was derived using Newcastle-Ottawa and Philips checklists. Extracted study data were used to compare study method and resulting burden estimate, according to perspective. Monetary costs were converted into 2013 USD. Results Out of 5187 unique retrievals, 214 studies were included. One hundred eighty-seven studies estimated patient health, 75 studies estimated payer/provider and 11 studies estimated economic burden. 64% of included studies were single centre. The majority of studies estimating patient or provider/payer burden used regression techniques. 48% of studies estimating mortality burden found a significant impact from resistance, excess healthcare system costs ranged from non-significance to $1 billion per year, whilst economic burden ranged from $21,832 per case to over $3 trillion in GDP loss. Median quality scores (interquartile range) for patient, payer/provider and economic burden studies were 0.67 (0.56-0.67), 0.56 (0.46-0.67) and 0.53 (0.44-0.60) respectively. Conclusions This study highlights what methodological assumptions and biases can occur dependent on chosen outcome and perspective. Currently, there is considerable variability in burden estimates, which can lead in-turn to inaccurate intervention evaluations and poor policy/investment decisions. Future research should utilise the recommendations presented in this review. Trial registration This systematic review is registered with PROSPERO (PROSPERO CRD42016037510).

Abstract
Liver cirrhosis is the 10th most common cause of death in Western world and infection is associated with a high morbidity and mortality, and represents the leading cause of acute liver decompensation. Patients with end-stage liver disease exhibit an important impairment of immune system. This condition, called cirrhosis-associated immune dysfunction, summarizes both local and systemic immune system alterations in liver cirrhosis that play a pivotal role in determining both the high incidence of infections and the ominous infections related mortality in this population. Another concerning feature of infections in cirrhotic patients is the growing prevalence of multidrug- resistant or extensively drug-resistant pathogens, which are associated with higher mortality, increased length of in-hospital stay and higher healthcare related costs if compared with infection caused by susceptible strains. Finally, patient with liver cirrhosis have several unique pathophysiological characteristics including hypoalbuminemia and reduction binding to proteins; altered distribution; altered clearance of the antimicrobials that can affect the pharmacokinetic/ pharmacodynamic of antimicrobials.

Are third-generation cephalosporins still the empirical antibiotic treatment of community-acquired spontaneous bacterial peritonitis? A systematic review and meta-analysis. Eur J Gastroenterol Hepatol 2018; 30:329-336.

Abstract
BACKGROUND Spontaneous bacterial peritonitis (SBP) is a common complication among cirrhotic patients. Guidelines recommend third-generation cephalosporins (3GCs) as empiric antibiotic therapy (EAT) of SBP. Recently, a broad-spectrum EAT was shown to be more effective than cephalosporins in the treatment of nosocomial spontaneous bacterial peritonitis (N-SBP); however, the prevalence of 3GCs-resistant bacteria is high in the nosocomial setting and broad-spectrum EAT cannot be used in all cases of SBP. AIM The aim of this study was to evaluate the 3GCs resistance distribution between N-SBP and community-acquired spontaneous bacterial peritonitis (CA-SBP) to clarify whether 3GCs are still an effective therapeutic intervention for CA-SBP. METHODS We searched for studies that reported the aetiology of SBP and the resistance profile of both gram-positive and gram-negative bacteria in MEDLINE and Google Scholar databases (since 1 January 2000 to 30 April 2017). A meta-analysis was carried out to estimate the risk difference [relative risk (RR) and 95% confidence intervals (CIs)] for 3GCs resistance in N-SBP and CA-SBP. Heterogeneity was assessed using the I-test. RESULTS A total of eight studies were included, including 1074 positive cultures of ascitic fluid in cirrhotic patients; 462 positive cultures were from N-SBP and, among these, 251 (54.3%) were 3GCs resistant. Six hundred and twelve positive cultures were from CA-SBP and, among these, 207 (33.8%) were 3GCs-resistant SBP. A pooled RR of 3GCs resistance in N-SBP compared with CA-SBP showed a significant difference (RR=1.67, 95% CI: 1.14-2.44; P=0.008). We carried out two subgroup analyses: the first according to the median year of study observation (before vs. since 2008) and the second according to the country of the study (China vs. others). The studies carried out before 2008 (327 SBP-positive culture) showed a significantly higher risk for 3GCs-resistant strains in N-SBP compared with CA-SBP (RR=2.36, 95% CI: 1.39-3.99; P=0.001), whereas this was not found in SBP acquired after 2008 (RR=1.24, 95% CI: 0.83-1.84; P=0.29). N-SBP occurring in China had no significantly higher risk for 3GCs-resistant strains compared with CA-SBP (RR=1.44, 95% CI: 0.87-2.37; P=0.16). CONCLUSION Our findings suggest that although the pooled RR of 3GCs resistance in N-SBP compared with CA-SBP show that 3GCs are still an effective option for the treatment of CA-SBP, the subanalysis of studies that enroled patients in the last decade did not show a significant higher RR of 3GCs resistance in N-SBP compared with CA-SBP. Therefore, in centres where local patterns of antimicrobial susceptibility (with low rates of 3GCs resistance) are not available, 3GCs should not be used initially for CA-SBP treatment. Future studies are needed to confirm this trend of 3GCs resistance.

Abstract
Background and aims Current guidelines recommend antibiotic prophylaxis in all patients presenting with cirrhosis and acute variceal hemorrhage (AVH). We aimed to evaluate the characteristics and clinical impact of "early" infections (developing within 14 days) of AVH in a real-world setting. Methods We analyzed retrospective data from a cohort of 371 adult patients with cirrhosis and AVH all of whom had received antibiotic prophylaxis (74% men; mean age 56 years), admitted to tertiary care hospitals in Edmonton, Alberta, Canada, and Barcelona, Spain. Sensitivity analyses were presented for culture-positive (confirmed) infections. Results The mean MELD was 16. Fifty-two percent of patients received quinolones, 45% third-generation cephalosporins and 3% other antibiotics. Fourteen percent (51/371) developed an infection within 14 days of AVH. Seventy-five percent of infections were culture positive and occurred at a mean of six days from AVH. When all infections were considered, respiratory infections were the most common (53%) followed by urinary tract infections (17%) and bacteremia (16%). Resistance patterns differed between countries. Outpatient antibiotic prophylaxis (OR 5.4) and intubation (OR 2.6) were independent predictors of bacterial infection. Bacterial infection (OR 2.6) and the MELD (OR 1.2) were independent predictors of six-week mortality. Conclusions Early bacterial infections develop in 14% of cirrhotic patients with AVH despite antibiotic prophylaxis, and have a negative impact on six-week mortality. Intubation and outpatient antibiotic prophylaxis are associated with increased risk of early bacterial infections. Patients at risk should be followed closely with prompt infection workup and local antibiogram-based expansion of antibiotic therapy in case of clinical decline.

Abstract
BACKGROUND Spontaneous bacterial peritonitis (SBP) can be life threatening in patients with liver cirrhosis. In contrast to community-acquired SBP, no standard treatment has been established for healthcare-related and nosocomial SBP. MATERIALS AND METHODS We prospectively collected healthcare-related and nosocomial SBP cases from March 2012 till February 2016 at the Department of Internal Medicine I of the University of Bonn and analysed the prevalence of antibiotic resistance among the isolated bacteria. SBP was diagnosed according to international guidelines. Ciprofloxacin, ceftriaxone and meropenem were used as reference substance for resistance to quinolones, third-generation cephalosporins and carbapenems, respectively. RESULTS Ninety-two SBP episodes in 86 patients were identified: 63 episodes (69%) were nosocomial. Escherichia coli, Klebsiella species, enterococci and streptococci were most frequently isolated. Frequencies of these microorganisms were comparable for healthcare-related and nosocomial SBP (14% vs. 11%, 14% vs. 8%, 14% vs. 5% and 10% vs. 6%, respectively). In general, antibiotic resistance was higher in isolates from nosocomial than from healthcare-related SBP (50% vs. 18% for quinolones, 30% vs. 11% for piperacillin-tazobactam; P > 0·05), but comparable concerning third-generation cephalosporins (30% vs. 33%). All microorganisms were sensitive to carbapenems apart from nosocomial infections with Enterococcus faecium (n = 3) and Candida albicans (n = 1) due to intrinsic resistance or lack of microbiological efficacy, respectively. No multidrug-resistant microorganisms were detected. Resistance to initial antibiotic treatment affected 30-day survival negatively (18% vs. 68%; P = 0·002). CONCLUSION Resistance to initial antibiotic treatment was associated with increased mortality. With resistance to cephalosporins being frequent, piperacillin-tazobactam or carbapenems might be preferred as treatment of SBP.

Abstract
Antimicrobial resistance has become a major global public health security problem that needs coordinated approaches at regional, national and international levels. Antibiotic overuse and the failure of control measures to prevent the spread of resistant bacteria in the healthcare environment have led to an alarming increase in the number of infections caused by resistant bacteria, organisms that resist many (multi-drug and extensively drug-resistant strains), if not all (pan-drug-resistant bacteria) currently available antibiotics. While Gram-positive cocci resistance (methicillin-resistant Staphylococcus aureus and vancomycin-resistant enterococci) shows a heterogeneous geographical distribution, extended-spectrum β-lactamase-producing Enterobacteriaceae and carbapenem-resistant Enterobacteriaceae have become pandemic worldwide and endemic in some parts of the world, respectively. Moreover, currently available therapeutic options for resistant bacteria are very limited, with very few new agents in development. Antimicrobial resistance is especially relevant in decompensated cirrhosis. Firstly, cirrhotic patients are highly susceptible to develop infections caused by resistant bacteria as risk factors of multiresistance concentrate in this population (mainly repeated hospitalizations and antibiotic exposure). Secondly, inappropriate empirical antibiotic schedules easily translate into increased morbidity (acute kidney injury, acute-on-chronic liver failure, septic shock) and hospital mortality in advanced cirrhosis. Therefore, hepatologists must face nowadays a complex clinical scenario that requires new empirical antibiotic strategies that may further spread resistance. Global, regional and local preventive measures should therefore be implemented to combat antimicrobial resistance in cirrhosis including the restriction of antibiotic prophylaxis to high-risk populations, investigation on non-antibiotic prophylaxis, stewardship programs on adequate antibiotic prescription and on increasing awareness of the problem among health professionals, and well-defined early de-escalation policies based on rapid microbiological diagnostic tests. Other infection control practices such as hand hygiene and barrier precautions are also important. Clinical impact and cost-effectiveness of epidemiological surveillance programs (periodic rectal and nasal swabs) should also be explored.

Abstract
UNLABELLED Patients with cirrhosis, particularly those with decompensated cirrhosis, are at increased risk of bacterial infections that may further precipitate other liver decompensations including acute-on-chronic liver failure. Infections constitute the main cause of death in patients with advanced cirrhosis, and strategies to prevent them are essential. The main current strategy is the use of prophylactic antibiotics targeted at specific subpopulations at high risk of infection: prior episode of spontaneous bacterial peritonitis, upper gastrointestinal bleeding, and low-protein ascites with associated poor liver function. Antibiotic prophylaxis effectively prevents not only the development of bacterial infections in all these indications but also further decompensation (variceal bleeding, hepatorenal syndrome) and improves survival. However, antibiotic prophylaxis is also associated with a clinically relevant and increasing drawback, the development of infections due to multidrug-resistant organisms. Several strategies have been suggested to balance the risks and benefits of antibiotic prophylaxis. CONCLUSION Antibiotic stewardship principles such as the restriction of antibiotic prophylaxis to subpopulations at a very high risk for infection, the avoidance of antibiotic overuse, and early deescalation policies are key to achieve this balance; nonantibiotic prophylactic measures such as probiotics, prokinetics, bile acids, statins, and hematopoietic growth factors could also contribute to ameliorate the development and spread of multidrug-resistant bacteria in cirrhosis.

Abstract
INTRODUCTION ascites is one of the most common complications of cirrhosis associated with a high rate of mortality. Although several scores have been developed in order to assess the prognosis of the disease, they were designed for predicting liver transplantation requirements and mortality in the short term, but not while in hospital. The aim of this study was to weigh risk factors for in-hospital mortality in adult patients with ascites due to alcoholic cirrhosis. MATERIAL AND METHODS we performed a cross-sectional study in 180 adult patients with diagnosis of cirrhosis with portal hypertension associated with high alcohol intake. The diagnosis of cirrhosis was made by liver echography and portal hypertension was defined by clinical features plus serum-ascites albumin gradient. Sampled individuals were subjected to complete clinical examination. Child Pugh and the MELD scores were applied in all the patients. RESULTS nineteen patients died while in-hospital. Mortality was associated with increased levels of serum white blood cell, urea, creatinine, prolonged prothrombin time, aspartate aminotransferase and alanine aminotransferase. We conducted a multiple binary logistic to predict in-hospital mortality which yielded that serum urea, creatinine and prothrombin time made a significant contribution to prediction with an OR 14 (95% CI 12.8 - 16.7 p = 0.03), 2 (95% CI 0.5 - 3.47, p = 0.04), and 2 (95% CI 1.03 - 2.31, p = 0.01) linearly-related. CONCLUSIONS our results suggest that acute renal failure and prolonged prothrombin time are predictors of in-hospital mortality in patients with portal hypertension due to alcoholic cirrhosis.
