Abstract
Abstract
Background
Bacterial translocation is considered the pathophysiological hallmark in the development of spontaneous bacterial peritonitis (SBP). Prokinetics can increase gastrointestinal (GIT) motility, reduce small bowel transit time, decrease bacterial translocation, and the possibility of SBP. The aim of this work was to compare the effectiveness and safety of itopride and norfloxacin versus norfloxacin only in secondary prophylaxis for cirrhotic ascitic patients with spontaneous bacterial peritonitis.
Results
Regarding the baseline clinical manifestations and laboratory investigations, there was no significant difference between both groups. The incidence of a recurrent SBP in group I, who had received itopride plus norfloxacin, reduced with a significant difference than other group II (P=0.018). The median time for recurrence of SBP was highly longer in group I than group II with a significant difference (P=0.042).
Conclusions
The combined usage of itopride with norfloxacin in patients with cirrhosis and ascites can decrease the occurrence of a recurrent SBP and significantly improve the survival of patients.

Abstract
BACKGROUND AND AIM Spontaneous bacterial peritonitis is a potentially life-threatening infection in patients with liver cirrhosis and ascites. Its prevention is vital to improve prognosis of cirrhotic patients. The main objective of this systematic review was to evaluate what is the most efficacious and safest antibiotic prophylactic strategy. METHODS Studies were located by searching PubMed and Cochrane Central Register of Controlled Trials in The Cochrane Library until February 2019. Randomized controlled trials evaluating primary or secondary spontaneous bacterial peritonitis prophylaxis in cirrhotic patients with ascites were included. The selection of studies was performed in two stages: screening of titles and abstracts, and assessment of the full papers identified as relevant, considering the inclusion criteria. Data were extracted in a standardized way and synthesized qualitatively. RESULTS Fourteen studies were included. This systematic review demonstrated that daily norfloxacin is effective as a prophylactic antibiotic for the prevention of spontaneous bacterial peritonitis in patients with cirrhosis. Once weekly ciprofloxacin was not inferior to once daily norfloxacin, with good tolerance and no induced resistance. Trimethoprim-sulfamethoxazole and norfloxacin have similar efficacy for primary and secondary prophylaxis of spontaneous bacterial peritonitis, however, trimethoprim-sulfamethoxazole was associated with an increased risk of developing an adverse event. Rifaximin was more effective than norfloxacin in the secondary prophylaxis of spontaneous bacterial peritonitis, with a significant decrease in adverse events and mortality rate. CONCLUSIONS Continuous long-term selective intestinal decontamination with norfloxacin is the most widely used prophylactic strategy in spontaneous bacterial peritonitis, yet other equally effective and safe options are available.

Abstract
SCOPE Pathological bacterial translocation from the disrupted intestinal barrier leads to substantial complications and mortality in liver cirrhosis. Vitamin D is reported as beneficial to gut barriers in some animal models. However, its effect on cirrhotic bacterial translocation is unknown. The authors aim to investigate the effects of calcitriol on bacterial translocation in cirrhotic rats. METHODS AND RESULTS Cirrhotic rats are administrated with a 2-week course of active vitamin D3 (calcitriol, 0.1 μg kg-1 per day) or vehicle by oral gavage after thioacetamide (TAA) injection for 16 weeks. Bacterial translocation, gut permeability, gut microbiota, and associated mechanisms are investigated. Calcitriol treatment significantly attenuates bacterial translocation and reduces intestinal permeability in TAA-induced cirrhotic rats. It upregulates the expressions of occludin in the small intestine and claudin-1 in the colon of cirrhotic rats directly independent of intrahepatic status. Even when a short period of calcitriol treatment do not reduce intestinal bacterial overgrowth, it induces a remarkable change of bacterial diversities and enrichment of Muribaculaceae, Bacteroidales, Allobaculum, Anaerovorax, and Ruminococcaceae. CONCLUSION Calcitriol treatment attenuates intestinal permeability, reduces bacterial translocation, and enriches potentially beneficial gut microbiota in cirrhotic rats that may enable it as a potential therapeutic agent to prevent cirrhotic complications.

Abstract
BACKGROUND The efficacy of antibiotic prophylaxis to prevent spontaneous bacterial peritonitis (SBP) in patients colonized with multidrug-resistant organisms (MDROs) is unknown. We evaluated the effectiveness of fluoroquinolone-based SBP prophylaxis in an era and area of frequent antibiotic resistance. METHODS This is a prospective observational study in patients with liver cirrhosis and an indication for fluoroquinolone-based prophylaxis of SBP. Patients were recruited and followed in a large German tertiary reference center with comprehensive microbiological and clinical monitoring performed at baseline and after 30, 60, 90, and 180 days of prophylaxis. RESULTS Overall, 77 patients received antibiotic prophylaxis for an average of 93 days. Baseline prevalence of colonization with MDROs was high (N = 39, 50.6%). At least one de novo MDRO was detected in 27 patients (35.1%) during antibiotic prophylaxis; 33 patients (42.9%) developed secondary infections, including 14 cases (17.9%) of infections with MDROs, and 13 cases (16.9%) of de novo/recurrent SBP. Thirty patients (39.0%) died during follow-up. Significantly higher risks of SBP development during antibiotic prophylaxis were observed for patients with versus without any apparent MDROs (P = .009), vancomycin-resistant enterococci (P = .008), multidrug-resistant gram-negative bacteria (P = .016), or quinolone-resistant gram-negative bacteria (QR-GNB) (P = .015). In competing risk analysis, QR-GNB were independently associated with prophylaxis failure (hazard ratio, 3.39; P = .045) and infections with QR-GNB were independently associated with death before SBP (subdistribution hazard risk, 6.47; P = .034). CONCLUSIONS Antibiotic prophylaxis of SBP appears to be less efficient in patients with known MDROs. Regular MDRO screening seems to be useful to tailor treatment of secondary infections and re-evaluate antibiotic prophylaxis in case of selection of quinolone resistance.

Abstract
BACKGROUND Spontaneous bacterial peritonitis (SBP) is an important prognostic factor for outcomes in patients with cirrhosis. Antibiotic prophylaxis is recommended in patients at high risk for developing SBP, but the choice of antibiotics remains unclear.
AIM To evaluate the efficacy of various antibiotics for prophylaxis of SBP based on randomized control trials (RCTs).
METHODS Electronic databases were searched through November 2018 for RCTs evaluating the efficacy of therapies for primary or secondary prophylaxis of SBP. The primary outcome was the development of SBP. Sensitivity analyses limited to studies of primary or secondary prophylaxis and studies reported after 2010 were performed. The secondary outcome was the risk of all-cause mortality or transplant. The outcomes were assessed by rank of therapies based on network meta-analyses. Individual meta-analyses were also performed.
RESULTS Thirteen RCTs (1742 patients) including norfloxacin, ciprofloxacin, rifaximin, trimethoprim-sulfamethoxazole (TMP-SMX), or placebo/no comparator were identified. Individual meta-analyses showed superiority of rifaximin over norfloxacin as well as norfloxacin and TMP-SMX over placebo. Network meta-analysis demonstrated the rank of efficacy in reducing the risk of SBP as: Rifaximin, ciprofloxacin, TMP-SMX, norfloxacin, and placebo/no comparator. Rifaximin ranked highest in sensitivity analyses limited to studies of primary or secondary prophylaxis and studies reported after 2010. Similarly, rifaximin ranked highest in reducing the risk of death/transplant.
CONCLUSION The present comprehensive network meta-analysis provides RCT based evidence for superior efficacy of rifaximin compared to other antibiotics for the prophylaxis of SBP and reducing risk of death/transplant. Further RCTs are warranted to confirm our findings.

Abstract
BACKGROUND Approximately 2.5% of all hospitalisations in people with liver cirrhosis are for spontaneous bacterial peritonitis. Spontaneous bacterial peritonitis is associated with significant short-term mortality; therefore, it is important to prevent spontaneous bacterial peritonitis in people at high risk of developing it. Antibiotic prophylaxis forms the mainstay preventive method, but this has to be balanced against the development of drug-resistant spontaneous bacterial peritonitis, which is difficult to treat, and other adverse events. Several different prophylactic antibiotic treatments are available; however, there is uncertainty surrounding their relative efficacy and optimal combination. OBJECTIVES To compare the benefits and harms of different prophylactic antibiotic treatments for prevention of spontaneous bacterial peritonitis in people with liver cirrhosis using a network meta-analysis and to generate rankings of the different prophylactic antibiotic treatments according to their safety and efficacy. SEARCH METHODS We searched CENTRAL, MEDLINE, Embase, Science Citation Index Expanded, World Health Organization International Clinical Trials Registry Platform, and trials registers to November 2018 to identify randomised clinical trials in people with cirrhosis at risk of developing spontaneous bacterial peritonitis. SELECTION CRITERIA We included only randomised clinical trials (irrespective of language, blinding, or status) in adults with cirrhosis undergoing prophylactic treatment to prevent spontaneous bacterial peritonitis. We excluded randomised clinical trials in which participants had previously undergone liver transplantation, or were receiving antibiotics for treatment of spontaneous bacterial peritonitis or other purposes. DATA COLLECTION AND ANALYSIS We performed a network meta-analysis with OpenBUGS using Bayesian methods and calculated the odds ratio, rate ratio, and hazard ratio (HR) with 95% credible intervals (CrI) based on an available-case analysis, according to National Institute of Health and Care Excellence Decision Support Unit guidance. MAIN RESULTS We included 29 randomised clinical trials (3896 participants; nine antibiotic regimens (ciprofloxacin, neomycin, norfloxacin, norfloxacin plus neomycin, norfloxacin plus rifaximin, rifaximin, rufloxacin, sparfloxacin, sulfamethoxazole plus trimethoprim), and 'no active intervention' in the review. Twenty-three trials (2587 participants) were included in one or more outcomes in the review. The trials that provided the information included people with cirrhosis due to varied aetiologies, with or without other features of decompensation, having ascites with low protein or previous history of spontaneous bacterial peritonitis. The follow-up in the trials ranged from 1 to 12 months. Many of the trials were at high risk of bias, and the overall certainty of evidence was low or very low. Overall, approximately 10% of trial participants developed spontaneous bacterial peritonitis and 15% of trial participants died. There was no evidence of differences between any of the antibiotics and no intervention in terms of mortality (very low certainty) or number of serious adverse events (very low certainty). However, because of the wide CrIs, clinically important differences in these outcomes cannot be ruled out. None of the trials reported health-related quality of life or the proportion of people with serious adverse events. There was no evidence of differences between any of the antibiotics and no intervention in terms of proportion of people with 'any adverse events' (very low certainty), liver transplantation (very low certainty), or the proportion of people who developed spontaneous bacterial peritonitis (very low certainty). The number of 'any' adverse events per participant was fewer with norfloxacin (rate ratio 0.74, 95% CrI 0.59 to 0.94; 4 trials, 546 participants; low certainty) and sulfamethoxazole plus trimethoprim (rate ratio 0.19, 95% CrI 0.02 to 0.81; 1 trial, 60 participants; low certainty) versus no active intervention. There was no evidence of differences between the other antibiotics and no intervention in the number of 'any' adverse events per participant (very low certainty). There were fewer other decompensation events with rifaximin versus no active intervention (rate ratio 0.61, 65% CrI 0.46 to 0.80; 3 trials, 575 participants; low certainty) and norfloxacin plus neomycin (rate ratio 0.06, 95% CrI 0.00 to 0.33; 1 trial, 22 participants; low certainty). There was no evidence of differences between the other antibiotics and no intervention in the number of decompensations events per participant (very low certainty). None of the trials reported health-related quality of life or development of symptomatic spontaneous bacterial peritonitis. One would expect some correlation between the above outcomes, with interventions demonstrating effectiveness across several outcomes. This was not the case. The possible reasons for this include sparse data and selective reporting bias, which makes the results unreliable. Therefore, one cannot draw any conclusions from these inconsistent differences based on sparse data. There was no evidence of any differences in the subgroup analyses (performed when possible) based on whether the prophylaxis was primary or secondary. FUNDING the source of funding for five trials were organisations who would benefit from the results of the study; six trials received no additional funding or were funded by neutral organisations; and the source of funding for the remaining 18 trials was unclear. AUTHORS' CONCLUSIONS Based on very low-certainty evidence, there is considerable uncertainty about whether antibiotic prophylaxis is beneficial, and if beneficial, which antibiotic prophylaxis is most beneficial in people with cirrhosis and ascites with low protein or history of spontaneous bacterial peritonitis. Future randomised clinical trials should be adequately powered, employ blinding, avoid postrandomisation dropouts (or perform intention-to-treat analysis), and use clinically important outcomes such as mortality, health-related quality of life, and decompensation events.

Abstract
Bacterial infection remains a leading cause of mortality and morbidity for patients with cirrhosis, with hospitalization, alterations in the intestinal microbiota, and therapeutic drugs all implicated in its development. Bacterial infections also remain the most common precipitant of acute-on-chronic liver failure, with infection occurring as a direct consequence of the progression of this syndrome. Furthermore, recent epidemiological analyses have demonstrated that infections due to multidrug-resistant bacteria are occurring with increasing frequency in patients with cirrhosis. Despite significant advances in the understanding of the pathophysiological processes triggered by an infection in patients with cirrhosis, a demonstrable survival benefit for the sickest patients who require ICU admission has not yet occurred. Early diagnosis of infection and appropriate antimicrobial treatment is essential to ensuring optimal outcomes for these patients. This review provides an evidence-based analysis of both the current strategies for prevention and the recommended management of common bacterial infections in patients with cirrhosis.

Abstract
Background and aims Hepatitis B virus-related decompensated cirrhosis is difficult to cure but has a high readmission rate due to multiple complications. Our aim was to investigate the diagnostic potential value of plasma diamine oxidase (DAO) for 6-month readmission of patients with HBV-related decompensated cirrhosis. Methods A total of 135 patients with HBV-related decompensated cirrhosis were prospectively collected at the onset of discharge of hospital, and then were followed up for at least 6 months with the readmission as the primary outcome. The plasma DAO level was measured using enzyme linked immunosorbent assay. In addition, 120 age and sex matched patients with HBV-related compensated cirrhosis were included as controls. Results A total of 36 patients (36.7%) with decompensated cirrhosis admitted to hospital during the 6-month follow up. The plasma DAO level of readmission group [21.1 (14.5; 29.0) ng/ml] was significantly higher than that in the non-readmission group [12.7 (9.3; 18.0) ng/mL, P < 0.001]. Multivariate analysis showed that the plasma DAO level (HR = 1.102, P < 0.05) and hepatic encephalopathy (HE) (HR = 5.018, P < 0.05) were independent factors for 6-month readmission of decompensated cirrhosis. DAO level showed higher area under the curve of receiver operating characteristic (AUROC) than HE (0.769 vs. 0.598, P < 0.05) and Child-Pugh-Turcotte (CPT) score (0.769 vs. 0.652, P < 0.05) for predicting 6-month readmission rate, with the best cut-off value as 19.7 ng/mL. Furthermore, plasma DAO level (HR = 1.184, P < 0.05) was an independent factor and has the higher AUROC than CPT score for the onset of recurrent HE (0.905 vs. 0.738, P < 0.05) during the 6-month follow up. Conclusions Plasma DAO level > 19.7 ng/mL predicts high rate of 6-month readmission in patients with HBV-related decompensated cirrhosis.

Abstract
OBJECTIVE To examine whether baseline model for end-stage liver disease (MELD) score in patients with cirrhosis and ascites predicts the future development of first spontaneous bacterial peritonitis (SBP) episode. METHODS A retrospective case-control study was performed at three academic centers to select patients admitted with first SBP episode (cases) and those with ascites admitted for decompensation without SBP (controls). Medical records from these centers were reviewed between January 1, 2008, and December 31, 2013. Cases and controls were matched (1:2) for age, sex, and race. Conditional logistic recession models were built to determine whether baseline MELD score (within a month before hospitalization) predicts first SBP episode. RESULTS Of 697 patients (308, 230, and 159 from centers A, B, and C, respectively), cases and controls were matched in 94%, 89%, and 100% at three respective centers. In the pooled sample, probability of SBP was 11%, 31%, 71%, and 93% at baseline MELD scores less than or equal to 10, from 11 to 20, from 21 to 30, and greater than 30, respectively. Compared with MELD score less than or equal to 10, patients with MELD scores from 11 to 20, 21 to 30, and greater than 30 had six- (3- to 11-), 29- (12- to 69-), and 115- (22- to 598-) folds (95% CI) risk of SBP, respectively. Based on different MELD score cutoff points, MELD score greater than 17 was most accurate in predicting SBP occurrence. Analyzing 315 patients (152 cases) with available data on ascitic fluid protein level controlling for age, sex, and center, MELD score but not ascitic fluid protein associated with first SBP episode with respective odds ratios of 1.20 (1.14 to 1.26) and 0.88 (0.70 to 1.11). CONCLUSION Baseline MELD score predicts first SBP episode in patients with cirrhosis and ascites.

Abstract
Introduction: Spontaneous bacterial peritonitis represents a frequent and severe complication in cirrhotic patients with ascites. In daily practice, the diagnosis of spontaneous bacterial peritonitis might be challenging in the absence of the typical signs and symptoms of infection such as fever or leukocytosis. Areas covered: Aim of this review is to revise the current state of the art on primary and secondary spontaneous bacterial peritonitis. Literature search in Medline/Pubmed was performed. Expert opinion: Historically, gram-negative bacteria were the most frequent etiologic agents of spontaneous bacterial peritonitis, with Escherichia coli and Klebsiella spp. being the most frequently isolated bacteria. However, major changes in this regard occurred over the last few decades with an increasing prevalence of gram-positive, quinolone-resistant, and multidrug-resistant bacteria. In particular, the increasing prevalence of quinolone-resistant bacteria challenged the prominent role of norfloxacin in spontaneous bacterial peritonitis prevention. Given the high mortality rate and the risk of developing the hepatorenal syndrome, prophylaxis of spontaneous bacterial peritonitis is indicated in three high-risk populations: patients with acute gastrointestinal hemorrhage, patients with low total protein content in ascitic fluid and advanced cirrhosis, and patients with a previous history of spontaneous bacterial peritonitis (secondary prophylaxis).

Abstract
BACKGROUND & AIMS Several antibiotic treatments aiming to prevent spontaneous bacterial peritonitis (SBP) in cirrhotic patients with low-protein content in ascitic fluid have been tested; however, there are limited data on the comparative efficacy of these regimens. We assessed their comparative efficacy through a network meta-analysis and using GRADE criteria to appraise quality of evidence. METHODS Through literature review through October 2018, we identified 10 randomized controlled trials comparing antibiotic treatments (norfloxacin, ciprofloxacin, trimethoprim/sulfamethoxazole and rifaximin) with each other or placebo. Primary outcome was SBP occurrence, with mortality rate and rate of other infections as secondary outcomes. RESULTS In comparison with placebo, moderate quality evidence supports the use of norfloxacin and ciprofloxacin in primary prophylaxis of SBP (risk ratio 0.23; 95% CI, 0.09-0.56; P = 0.001 and 0.23; 0.07-0.79; P = 0.02 respectively) while only low quality evidence suggests superiority of rifaximin (risk ratio 0.15; 0.05-0.42). When antimicrobial agents were compared to each other, no significant difference was found. With regard to mortality, moderate quality supports the superiority of norfloxacin over placebo (risk ratio, 0.68; 95% CI, 0.47-0.99; P = 0.04), while ciprofloxacin and rifaximin showed only a non-significant benefit and no significant difference was found in the other comparisons. None of the tested antibiotics proved to significantly decrease the rate of other infections. CONCLUSIONS Norfloxacin appears to have significant benefit both in terms of SBP prevention and mortality; ciprofloxacin represents a valuable option although without a clear survival benefit. Rifaximin shows interesting results but needs to be tested in further trials.

Abstract
For the prevention of spontaneous bacterial peritonitis (SBP) in cirrhotic patients with ascites, prophylactic antibiotics are recommended as a standard regimen. This study aimed to assess the efficacy of norfloxacin (N), ciprofloxacin (C), trimethoprim-sulfamethoxazole (T-S), and rifaximin (R) in the prevention of SBP. We searched the electronic databases including PubMed, Cochrane Library, Embase, and Web of Science from inception till 1 August 2018. The randomized-controlled trials that compared N, C, T-S, R, and placebo (P) were identified. A network meta-analysis (NMA) was carried out using the software STATA 14.0 and Revman 5.3. We included 16 studies involving 1984 participants in the NMA for SBP prevention. The NMA results showed that, compared with those treated with P (reference), patients treated with C, N, or R had a lower incidence of SBP and mortality. Similarly, the incidences of SBP and mortality for R were lower than those for N. The probabilities of ranking results showed that R ranked first with respect to the outcomes of the incidence of SBP and mortality. According to our results, R seemed to be the optimal regimen for protecting against SBP in patients with cirrhosis and ascites. However, considering the limitations of our study, additional high-quality studies are required in this respect.

Abstract
Cirrhosis affects millions of people around the world and is associated with increased morbidity and mortality. Spontaneous bacterial peritonitis (SBP) is a common complication of liver disease with cirrhosis and accounts for up to 30% of infections in patients with cirrhosis. Patients with a history of SBP and those deemed to be at high risk often are prescribed antibiotics to reduce the incidence of SBP. Fluoroquinolones and sulfamethoxazole-trimethoprim are commonly used antibiotics for long-term prevention for these specified populations; however, these antibiotics are associated with several adverse effects and interactions that may be harmful to patients. In addition, resistance development may decrease the efficacy of SBP treatment and prophylaxis. Given these limitations, rifaximin, a nonabsorbable, broad-spectrum antibiotic that is used for hepatic encephalopathy, may serve as a prophylactic alternative to conventional therapy. This review discusses guideline-recommended therapy and the evidence for using rifaximin for SBP prophylaxis.

Abstract
Dysbiosis of gut microbiota and metabolome is a frequently encountered condition in liver cirrhosis (LC) patients. The severity of liver dysfunction was found to be correlated with the degree of microbial dysbiosis. Several clinical studies have indicated liver function improvement after therapeutic splenectomy for LC-induced hypersplenism. We sought to determine whether such post-splenectomy outcome is pertinent to modulation of the abnormal gut microenvironment in LC patients. A cross-sectional study including 12 LC patients and 16 healthy volunteers was first conducted, then a before-after study in the cohort of patients was carried out before and 6 months after splenectomy. Fecal samples were collected in hospital. Temporal bacterial (n = 40) and metabolomics (n = 30) profiling was performed using 16s rRNA gene sequencing and ultra performance liquid chromatography/mass spectrometer (UPLC/MS), respectively. Our results revealed that microbial composition in patients was clearly different from that in healthy controls (HCs), evidenced by considerable taxonomic variation. Along with improved liver function (Child-Pugh score), the patients also displayed similar gut microbiota profile and predicted metagenome function to that of HCs after splenectomy. Enterobacteriaceae and Streptococcaceae, two LC-enriched families showing positive relation with Child-Pugh score, exhibited significantly decreased abundance after splenectomy. At the genus level, 11 genera were differentially abundant between patients and HCs, but 9 genera of them restituted to normal levels by certain degree after splenectomy. PICRUSt analysis showed that the relative abundance of 17 KEGG pathways was partially restored after splenectomy. Four of them were amino acid-related pathways: lysine degradation, tryptophan degradation, amino acid metabolism, and protein digestion and absorption. These findings were supported by metabonomics results which showed that relative abundance of amino acid and corresponding catabolites changed toward normal. In addition to the variations in the relative abundances of bacteria and metabolites, the correlation between them also altered in patients after splenectomy. Dysbiosis in gut microbiome and related metabolism of LC patients was partially corrected after splenectomy. Whether the improved gut microenvironment could prevent LC-related complications and delay the progress of LC is a propitious objective for future study. TRIAL REGISTRATION ChiCTR-OOB-15007409.

Abstract
Infections account for significant morbidity and mortality in liver cirrhosis and most are related to the gut microbiome. Fecal dysbiosis, characterized by an overgrowth of potentially pathogenic bacteria and a decrease in autochthonous non-pathogenic bacteria, becomes prominent with the progression of liver cirrhosis. In cirrhotic patients, disruption of the intestinal barrier causes intestinal hyperpermeability (i.e. leaky gut), which is closely related to gut dysmotility, dysbiosis and small intestinal bacterial overgrowth and may induce pathological bacterial translocation. Although the involved microbial taxa are somewhat different between the cirrhotic patients from the East and the West, the common manifestation of a shortage of bacteria that contribute to the production of short-chain fatty acids and secondary bile acids may facilitate intestinal inflammation, leaky gut and gut dysbiosis. Translocated endotoxin and bacterial DNA are capable of provoking potent inflammation and affecting the metabolic and hemodynamic systems, which may ultimately enhance the progression of liver cirrhosis and its various complications, such as hepatic encephalopathy (HE), variceal bleeding, infection and renal disturbances. Among studies on the microbiome-based therapeutics, findings of probiotic effects on HE have been contradictory in spite of several supportive results. However, the effects of synbiotics and prebiotics are substantially documented. The background of their effectiveness should be evaluated again in relation to the cirrhosis-related changes in gut microbiome and their metabolic effects. Strict indications for the antibiotic rifaximin remain unestablished, although its effect is promising, improving HE and other complications with little influence on microbial populations. The final goal of microbiome-based therapeutics is to adjust the gut-liver axis to the maximal benefit of cirrhotic patients, with the aid of evolving metagenomic and metabolomic analyses.

Abstract
BACKGROUND AND AIMS Spontaneous bacterial peritonitis (SBP) is a serious complication of liver cirrhosis with a high recurrence rate and a marked increase in mortality. Norfloxacin is used widely for the secondary prophylaxis of SBP; however, its extensive long-term use has led to an increase in the incidence of quinolone-resistant and Gram-positive SBP. Rifaximin is a nonabsorbable broad-spectrum antibiotic and does not appear to promote emergence of resistance. The aim of this study was to compare the safety and efficacy of rifaximin versus norfloxacin for the secondary prevention of SBP in patients with liver cirrhosis and ascites. MATERIALS AND METHODS Two hundred and sixty two cirrhotic patients with ascites and a previous episode of SBP were assigned randomly to receive either 1200 mg rifaximin or 400 mg of norfloxacin daily for 6 months. All patients were monitored clinically each month and with ascitic fluid examination at the end of 2 and 6 months if not clinically suspected of recurrence earlier. RESULTS Recurrence of SBP was significantly lower in the rifaximin group (3.88 vs. 14.13%) compared with the norfloxacin group (P=0.04). The mortality rate was significantly decreased in the rifaximin group (13.74 vs. 24.43%) compared with the norfloxacin group (P=0.044). The causes of death between the two groups did not show a significant difference (P=0.377), but encephalopathy-related deaths were three folds higher in the norfloxacin group. There was a significant decrease in the side effects in the rifaximin group versus the norfloxacin group (P=0.033). CONCLUSION Rifaximin was more effective than norfloxacin in the secondary prevention of SBP. Encephalopathy-related mortality and side effects were fewer in the rifaximin group.

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
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
A “leaky gut” may be the cutting edge for the passage of toxins, antigens or bacteria into the body, and may play a pathogenic role in advanced liver cirrhosis and its complications. Plasma endotoxin levels have been admitted as a surrogate marker of bacterial translocation and close relations of endotoxemia to hyperdynamic circulation, portal hypertension, renal, cardiac, pulmonary and coagulation disturbances have been reported. Bacterial overgrowth, increased intestinal permeability, failure to inactivate endotoxin, activated innate immunity are all likely to play a role in the pathological states of bacterial translocation. Therapeutic approach by management of the gut-liver axis by antibiotics, probiotics, synbiotics, prebiotics and their combinations may improve the clinical course of cirrhotic patients. Special concern should be paid on anti-endotoxin treatment. Adequate management of the gut-liver axis may be effective for prevention of liver cirrhosis itself by inhibiting the progression of fibrosis.

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
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
OBJECTIVE To prospectively compare norfloxacin (N) with trimethoprim-sulfamethoxazole (T-S) in preventing infection in cirrhotic patients. METHODS Cirrhotic patients at high risk of spontaneous bacterial peritonitis (SBP) were recruited and assigned N (400 mg daily) or T-S (160/800 mg daily). Patients were followed up for 12 months. The primary end-point was the incidence of infection. Secondary end-points included the incidence of SBP, bacteremia, extraperitoneal infection requiring antibiotic treatment, liver transplantation, death, side effects and rate of resistance to N or T-S. RESULTS A total of 80 patients with a mean age of 53.0 ± 9.3 years were prescribed N (n = 40) or T-S (n = 40). Child-Pugh status, model for end-stage liver disease and risk factors for SBP were similar between the groups. There were 10 episodes of infections in the N group and 9 in the T-S group (P = 0.79). Two patients each in the N and T-S group developed SBP (P = 0.60). There was a difference in the rate of transplantation favoring N (P = 0.03) but not death. The number of adverse events for N (n = 7) and T-S (n = 10) were similar (P = 0.59), with T-S being associated with an increased risk of developing a definite or probable adverse event compared to N (22.5% vs 0%, P = 0.01). CONCLUSIONS This study failed to demonstrate a difference between N and T-S groups in their effects on preventing infection in patients with liver cirrhosis. T-S can be considered an alternative first-line therapy for infection prophylaxis.

Abstract
The statements produced by the consensus conference on infection in end-stage liver disease promoted by the Italian Association for the Study of the Liver, are here reported. The topics of epidemiology, risk factors, diagnosis, prophylaxis, and treatment of infections in patient with compensated and decompensated liver cirrhosis were reviewed by a scientific board of experts who proposed 26 statements that were graded according to level of evidence and strength of recommendation, and approved by an independent jury. Each topic was explored focusing on the more relevant clinical questions. By systematic literature search of available evidence, comparison and discussion of expert opinions, pertinent statements answering specific questions were presented and approved. Short comments were added to explain the basis for grading evidence particularly on case of controversial areas.

Abstract
BACKGROUND The liver is the first line of defence against continuously occurring influx of microbial-derived products and bacteria from the gut. Intestinal bacteria have been implicated in the pathogenesis of alcoholic liver cirrhosis. Escape of intestinal bacteria into the ascites is involved in the pathogenesis of spontaneous bacterial peritonitis, which is a common complication of liver cirrhosis. The association between faecal bacterial populations and alcoholic liver cirrhosis has not been resolved. METHODS Relative ratios of major commensal bacterial communities (Bacteroides spp., Bifidobacterium spp., Clostridium leptum group, Enterobactericaea and Lactobacillus spp.) were determined in faecal samples from post mortem examinations performed on 42 males, including cirrhotic alcoholics (n = 13), non-cirrhotic alcoholics (n = 15), non-alcoholic controls (n = 14) and in 7 healthy male volunteers using real-time quantitative PCR (RT-qPCR). Translocation of bacteria into liver in the autopsy cases and into the ascites of 12 volunteers with liver cirrhosis was also studied with RT-qPCR. CD14 immunostaining was performed for the autopsy liver samples. RESULTS Relative ratios of faecal bacteria in autopsy controls were comparable to those of healthy volunteers. Cirrhotics had in median 27 times more bacterial DNA of Enterobactericaea in faeces compared to the healthy volunteers (p = 0.011). Enterobactericaea were also the most common bacteria translocated into cirrhotic liver, although there were no statistically significant differences between the study groups. Of the ascites samples from the volunteers with liver cirrhosis, 50% contained bacterial DNA from Enterobactericaea, Clostridium leptum group or Lactobacillus spp.. The total bacterial DNA in autopsy liver was associated with the percentage of CD14 expression (p = 0.045). CD14 expression percentage in cirrhotics was significantly higher than in the autopsy controls (p = 0.004). CONCLUSIONS Our results suggest that translocation of intestinal bacteria into liver may be involved as a one factor in the pathogenesis of alcoholic liver cirrhosis.

Abstract
BACKGROUND/AIMS Spontaneous bacterial peritonitis (SBP) has been known to greatly influence the survival rate of patients with liver cirrhosis. However, the factors that affect the survival rate in patients with SBP need to be clarified. METHODS This study enrolled 95 liver cirrhosis patients diagnosed with SBP. The laboratory findings of their serum and ascitic fluid were examined and the characteristics of the isolated microorganisms in their peritoneal fluid were analyzed. RESULTS The proportion of patients with culture-positive SBP was 41.1%, and 47 microorganisms were isolated from the ascitic fluid. The proportions of cultured bacteria that were Gram negative and Gram positive were 57.4% and 40.4%, respectively. The proportions of Escherichia coli, Klebsiella species, and Streptococcus species were 25.5%, 19.1%, and 19.1%, respectively. Enterococcus species represented 12.8% of the microorganisms cultured. The overall survival rates at 6, 12, and 24 months were 44.5%, 37.4%, and 32.2%, respectively. There was no relationship between the bacterial factors and the survival rate in SBP. Multivariate analysis revealed that the presence of hepatocellular carcinoma (HCC; P=0.001), higher serum bilirubin levels (≥3 mg/dL, P=0.002), a prolonged serum prothrombin time (i.e., international normalized ratio >2.3, P<0.001), renal dysfunction (creatinine >1.3 mg/dL, P<0.001), and lower glucose levels in the ascitic fluid (<50 mg/dL, P<0.001) were independent predictive factors of overall survival rate. CONCLUSIONS HCC, higher serum bilirubin levels, a prolonged serum prothrombin time, renal dysfunction, and lower ascitic glucose levels are associated with higher mortality rates in cirrhotic patients with SBP.

Abstract
Because of the anatomical position and its unique vascular system, the liver is susceptible to the exposure to the microbial products from the gut. Although large amount of microbes colonize in the gut, translocation of the microbes or microbial products into the liver and systemic circulation is prevented by gut epithelial barrier function and cleansing and detoxifying functions of the liver in healthy subjects. However, when the intestinal barrier function is disrupted, large amount of bacterial products can enter into the liver and systemic circulation and induce inflammation through their receptors. Nowadays, there have been various reports suggesting the role of gut flora and bacterial translocation in the pathogenesis of chronic liver disease and portal hypertension. This review summarizes the current knowledge about bacterial translocation and its contribution to the pathogenesis of chronic liver diseases and portal hypertension.

Abstract
Alcoholic liver disease (ALD) encompasses hepatic steatosis, which may progress to alcoholic hepatitis, fibrosis, and cirrhosis. It remains a leading cause of morbidity and mortality in the US and worldwide. The severity of liver disease correlates with plasma levels of bacterial products in patients, and experimental ALD depends on the level of gut derived bacterial products in rodents. Since intestinal decontamination and deficiency of bacterial product receptors or their downstream signaling molecules protect from alcohol-induced liver disease, bacterial translocation (BT), qualitative, and quantitative changes of the enteric microbiome are considered as being of fundamental importance in the pathogenesis of ALD. Recent enhancements in diagnostic technologies provide a better insight into these shifts. This review highlights vital events in ALD such as BT, the importance of Toll-like receptor (TLR) signaling, intestinal bacterial overgrowth (IBO), and changes in the intestinal microbiome. Furthermore, a treatment trial section of patients reviews possible future options of therapy for ALD modifying the enteric microbiome.

Abstract
The intestinal microflora is not only involved in the digestion of nutrients, but also in local immunity, forming a barrier against pathogenic microorganisms. The derangement of the gut microflora may lead to microbial translocation, defined as the passage of viable microorganisms or bacterial products (i.e., LPS, lipopeptides) from the intestinal lumen to the mesenteric lymph nodes and other extraintestinal sites. The most recent evidence suggests that microbial translocation (MT) may occur not only in cirrhosis, but also in the early stage of several liver diseases, including alcoholic hepatopathy and nonalcoholic fatty liver disease. Different mechanisms, such as small intestinal bacterial overgrowth, increased permeability of intestinal mucosa, and impaired immunity, may favor MT. Furthermore, MT has been implicated in the pathogenesis of the complications of cirrhosis, which are a significant cause of morbidity and mortality in cirrhotic subjects. Therapeutic strategies aiming at modulating the gut microflora and reducing MT have focused on antibiotic-based options, such as selective intestinal decontamination, and nonantibiotic-based options, such as prokinetics and probiotics. In particular, probiotics may represent an attractive strategy, even though the promising results of experimental models and limited clinical studies need to be confirmed in larger randomized trials.

Abstract
BACKGROUND Spontaneous bacterial peritonitis (SBP) may occur despite antibiotic prophylaxis. We investigated whether the addition of probiotics to norfloxacin enhances its efficacy in the prevention of SBP. METHODS A double-blind, randomized-controlled trial was conducted among consecutive cirrhotic patients who had either recovered from SBP (secondary prophylaxis) or who were at a high risk for the development of SBP (low ascitic fluid protein or serum bilirubin ≥ 2.5 mg/dl; primary prophylaxis). Norfloxacin 400 mg/day with probiotics capsules (Enterococcus faecalis JPC 30 million, Clostridium butyricum 2 million, Bacillus mesentericus JPC 1 million, Bacillus coagulans 50 million spores) at a dose of two capsules three times daily (group 1) or norfloxacin with a placebo (group 2) was given and the occurrence of SBP within a period of 6 months (primary endpoint) or side-effects of therapy and mortality (secondary endpoints) were recorded. RESULTS From April 2005 through August 2007, 110 patients were randomized to group 1 (n=55) or group 2 (n=55) and 45 (82%) and 43 (78%) of them completed the trial, respectively. The baseline characteristics were comparable. On intention-to-treat analysis, the cumulative probability of treatment failures was similar in both the groups [19/55 (34%) in group 1 vs. 20/55 (36%) in group 2, P=0.840]. The cumulative probability of mortality was also similar [13/45 (29%) in group 1 vs. 14/43 (32%) in group 2, P=0.834]. The frequency of side-effects was also comparable. In subgroup analyses, the frequencies of SBP and deaths were similar in the two groups in the subgroups of primary and secondary prophylaxes. The presence of encephalopathy and serum bilirubin of greater than 3.65 mg/dl were found to predict mortality independently. CONCLUSION The addition of probiotics to norfloxacin does not improve its efficacy in primary or secondary prophylaxis of SBP or in reducing the mortality in cirrhotic patients with ascites.

Abstract
Bacterial infections are very frequent in advanced cirrhosis and become the first cause of death of these patients. Despite numerous experimental data and significant advances in the understanding of the pathogenesis of sepsis in cirrhosis, the outcome remains poor. Classical diagnostic parameters such as C-reactive protein and SIRS criteria have less diagnostic capacity in the cirrhotic population, often delaying the diagnosis and the management of bacterial infection. Prompt and appropriate empirical antibiotic treatment of infection and early resuscitation of patients with severe sepsis or septic shock are essential in determining patient's outcome. A strategy of careful restriction of prophylactic antibiotics to the high-risk populations could reduce the spread of multidrug resistant bacteria. This review is focused on the currently recommended diagnostic, therapeutic and prophylactic strategies for bacterial infections in the cirrhotic population.

Ascites is the pathologic accumulation of fluid in the peritoneum. It is the most common complication of cirrhosis, with a prevalence of approximately 10%. Over a 10-year period, 50% of patients with previously compensated cirrhosis are expected to develop ascites. As a marker of hepatic decompensation, ascites is associated with a poor prognosis, with only a 56% survival 3 years after onset. In addition, morbidity is increased because of the risk of additional complications, such as spontaneous bacterial peritonitis and hepatorenal syndrome. Understanding the pathophysiology of ascites is essential for its proper management.

Abstract
PURPOSE Spontaneous bacterial peritonitis (SBP) frequently develops in patients with liver cirrhosis; however, there is little data to suggest whether the acquisition site of infection influences the prognosis. This study compared the bacteriology, clinical characteristics and treatment outcomes of community-acquired SBP (CA-SBP) and nosocomial SBP (N-SBP). MATERIALS AND METHODS The medical records of 130 patients with hepatitis B virus (HBV)-related liver cirrhosis, who had experienced a first episode of SBP between January 1999 and December 2008, were reviewed. RESULTS The study population included 111 (85.4%) patients with CA-SBP and 19 (14.6%) patients with N-SBP. Baseline and microbiological characteristics as well as clinical course, including in-hospital mortality, did not differ between patients with CA-SBP and those with N-SBP (all p>0.05). The median survival time was 6.5 months, and 117 (90.0%) patients died during the follow-up period. Patients with CA-SBP and N-SBP survived for median periods of 6.6 and 6.2 months, respectively, without significant difference (p=0.569). Time to recurrence did not differ between patients with CA-SBP and N-SBP (4.7 vs. 3.6 months, p=0.925). CONCLUSION The acquisition site of infection did not affect clinical outcomes for patients with HBV-related liver cirrhosis who had experienced their first episode of SBP. Third-generation cephalosporins may be effective in empirically treating these patients, regardless of the acquisition site of the infection.

Improving survival in decompensated cirrhosis. Int J Hepatol 2012; 2012:318627. [PMID: 22811919 PMCID: PMC3395145 DOI: 10.1155/2012/318627] [Citation(s) in RCA: 22] [Impact Index Per Article: 1.8] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 03/05/2012] [Revised: 04/30/2012] [Accepted: 05/03/2012] [Indexed: 12/11/2022] Open
Abstract
Mortality in cirrhosis is consequent of decompensation, only treatment being timely liver transplantation. Organ allocation is prioritized for the sickest patients based on Model for End Stage Liver Disease (MELD) score. In order to improve survival in patients with high MELD score it is imperative to preserve them in suitable condition till transplantation. Here we examine means to prolong life in high MELD score patients till a suitable liver is available. We specially emphasize protection of airways by avoidance of sedatives, avoidance of Bilevel Positive Airway Pressure, elective intubation in grade III or higher encephalopathy, maintaining a low threshold for intubation with lesser grades of encephalopathy when undergoing upper endoscopy or colonoscopy as pre transplant evaluation or transferring patient to a transplant center. Consider post-pyloric tube feeding in encephalopathy to maintain muscle mass and minimize risk of aspiration. In non intubated and well controlled encephalopathy, frequent physical mobility by active and passive exercises are recommended. When renal replacement therapy is needed, night-time Continuous Veno-Venous Hemodialysis may be useful in keeping the daytime free for mobility. Sparing and judicious use of steroids needs to be borne in mind in treatment of ARDS and acute hepatitis from alcohol or autoimmune process.

Potential preventability of spontaneous bacterial peritonitis. Dig Dis Sci 2011; 56:2728-34.

Abstract
BACKGROUND Antibiotic prophylaxis can reduce the incidence of the first episode and recurrent episodes of spontaneous bacterial peritonitis (SBP) in high-risk cirrhotic patients. However, recent data suggest that SBP prophylaxis may be underused. It is unclear how many cases of cirrhosis that develop SBP might actually be prevented with antibiotic prophylaxis. AIMS To determine the number of "preventable" cases of SBP and the adherence to standard guidelines for the use of antibiotic prophylaxis. METHODS A retrospective analysis of our patients diagnosed with SBP was performed. AASLD Guidelines (2004) for SBP prophylaxis include prior SBP, gastrointestinal (GI) hemorrhage, ascitic fluid (AF), protein ≤ 1 g/dl, or serum bilirubin ≥ 2.5 mg/dl. "Preventable (P) SBP" was defined as SBP occurring where prophylaxis was indicated but was not administered. "Non-preventable (NP) SBP" was defined as SBP that occurred despite proper adherence to the guidelines. "Inevitable (I) SBP" were those cases of SBP occurring in the absence of a documented indication for prophylaxis. RESULTS A total of 259 patients with cirrhosis underwent paracentesis; 29 had confirmed SBP. Eighteen of the 29 patients (62%) had "P-SBP", one (3%) had "NP-SBP", and ten (34%) had "I-SBP". In the P-SBP cases, the overlooked indications for prophylaxis were GI hemorrhage (n, %) (8, 44%), serum bilirubin ≥ 2.5 mg/dl (6, 33%), prior SBP (2, 11%) and AF protein ≤ 1 g/dl (2, 11%). Of the P-SBP, 78% were community-acquired; 22% were nosocomial. In-hospital mortality in the P-SBP was 16% (n = 3). Only one-third of patients who survived SBP received long-term outpatient prophylaxis after discharge. CONCLUSIONS Many cases of SBP could be prevented by adhering to the AASLD guidelines. GI hemorrhage is the most frequently overlooked indication for SBP prophylaxis. Studies identifying the reasons for non-adherence to guidelines and developing interventions to increase utilization are warranted.

Abstract
UNLABELLED Liver cirrhosis is the pathologic end stage of chronic liver disease. Increasing evidence suggests that gut flora is implicated in the pathogenesis of liver cirrhosis complications. The aim of this study was to characterize the fecal microbial community in patients with liver cirrhosis in comparison with healthy individuals. We recruited 36 patients with liver cirrhosis and 24 healthy controls. The fecal microbial communities was analyzed by way of 454 pyrosequencing of the 16S ribosomal RNA V3 region followed by real-time quantitative polymerase chain reaction. Community-wide changes of fecal microbiota in liver cirrhosis were observed compared with healthy controls. The proportion of phylum Bacteroidetes was significantly reduced (P=0.008), whereas Proteobacteria and Fusobacteria were highly enriched in the cirrhosis group (P=0.001 and 0.002, respectively). Enterobacteriaceae (P=0.001), Veillonellaceae (P=0.046), and Streptococcaceae (P=0.001) were prevalent in patients with cirrhosis at the family level. A positive correlation was observed between Child-Turcotte-Pugh (CTP) score and Streptococcaceae (R=0.386, P=0.02). Lachnospiraceae decreased significantly in patients with cirrhosis (P=0.004) and correlated negatively with CTP score (R=-0.49, P=0.002). Using partial least square discriminate analysis, we identified 149 operational taxonomic units (OTUs) as key phylotypes that responded to cirrhosis, most of which were Lachnospiraceae (65 OTUs), Streptococcaceae (23 OTUs), and Veillonellaceae (21 OTUs). CONCLUSION Fecal microbial communities are distinct in patients with cirrhosis compared with healthy individuals. The prevalence of potentially pathogenic bacteria, such as Enterobacteriaceae and Streptococcaceae, with the reduction of beneficial populations such as Lachnospiraceae in patients with cirrhosis may affect prognosis.

Abstract
Spontaneous bacterial peritonitis (SBP) is one of the most common and life-threatening complications of cirrhosis. It occurs in 10% to 30% of patients admitted to hospital and recent studies tend to demonstrate that SBP incidence seems to be decreasing in its frequency. A bacterial overgrowth with translocation through the increased permeable small intestinal wall and impaired defense mechanisms is considered to be the main mechanism associated with its occurrence. The Gram-negative aerobic bacteria are the major responsible for SBP episodes and Gram-positive bacteria, mainly Staphylococcus aureus, are being considered an emergent agent causing SBP. The prompt diagnosis of SBP is the key factor for reduction observed in mortality rates in recent years. The clinical diagnosis of SBP is neither sensitive nor specific and the search for new practical and available tools for a rapid diagnosis of SBP is an important endpoint of current studies. Reagent strips were considered a promising and faster way of SBP diagnosis. The prompt use of empirical antibiotics, mostly cefotaxime, improves significantly the short-term prognosis of cirrhotic patients with SBP. The recurrence rate of SBP is high and antibiotic prophylaxis has been recommended in high-risk settings. Unfortunately, the long-term prognosis remains poor.

Abstract
Antimicrobial prophylaxis is commonly used by clinicians for the prevention of numerous infectious diseases, including herpes simplex infection, rheumatic fever, recurrent cellulitis, meningococcal disease, recurrent uncomplicated urinary tract infections in women, spontaneous bacterial peritonitis in patients with cirrhosis, influenza, infective endocarditis, pertussis, and acute necrotizing pancreatitis, as well as infections associated with open fractures, recent prosthetic joint placement, and bite wounds. Perioperative antimicrobial prophylaxis is recommended for various surgical procedures to prevent surgical site infections. Optimal antimicrobial agents for prophylaxis should be bactericidal, nontoxic, inexpensive, and active against the typical pathogens that can cause surgical site infection postoperatively. To maximize its effectiveness, intravenous perioperative prophylaxis should be administered within 30 to 60 minutes before the surgical incision. Antimicrobial prophylaxis should be of short duration to decrease toxicity and antimicrobial resistance and to reduce cost.

Abstract
OBJECTIVES To evaluate the effect of long-term fluoroquinolone treatment before the biopsy in terms of post procedure sepsis. Three-week fluoroquinolone management before the biopsy may lower serum prostate specific antigen (PSA) levels and prevent unnecessary biopsies. METHODS A total of 558 patients were referred to our clinic for transrectal ultrasound (TRUS)-guided prostate biopsy. Of the patients, 205 had received levofloxacin 500 mg once a day for 3 weeks before the biopsy to lower the serum PSA levels (group 1). A total of 353 patients had not received any antibiotics before the procedure (group 2). In terms of the postbiopsy sepsis rate, group 1 and group 2 as well as patients who underwent biopsies in the early period and the latter period of the study were compared. RESULTS Sepsis was diagnosed in 17 patients (3.0%) after biopsy. Of these patients, 11 (5.4%) and 6 (1.7%) were in group 1 and group 2, respectively (P = .0297, OR: 3.28, 95% CI: 1.10-10.13). Sepsis was diagnosed in 7 patients (1.9%) and 10 patients (5.0%) in the early and the latter period of the study, respectively (P = .0771, OR: 0.38, 95% CI: .13-1.09). Escherichia coli was the causative agent in all patients with a positive culture. In addition, 1 patient also had meticillin-resistant Staphylococcus epidermidis (MRSE). All of the E. coli isolates were resistant to fluoroquinolones, and 55.6% were positive for extended spectrum β-lactamases (ESBL). CONCLUSIONS Long-term fluoroquinolone use to prevent unnecessary prostate biopsy may result in postbiopsy sepsis caused by fluoroquinolone resistant microorganisms.

Abstract
Ascites is one of the major complications of liver cirrhosis and is associated with a poor prognosis. It is important to distinguish noncirrhotic from cirrhotic causes of ascites to guide therapy in patients with noncirrhotic ascites. Mild to moderate ascites is treated by salt restriction and diuretic therapy. The diuretic of choice is spironolactone. A combination treatment with furosemide might be necessary in patients who do not respond to spironolactone alone. Tense ascites is treated by paracentesis, followed by albumin infusion and diuretic therapy. Treatment options for refractory ascites include repeated paracentesis and transjugular intrahepatic portosystemic shunt placement in patients with a preserved liver function. Potential complications of ascites are spontaneous bacterial peritonitis (SBP) and hepatorenal syndrome (HRS). SBP is diagnosed by an ascitic neutrophil count > 250 cells/mm3 and is treated with antibiotics. Patients who survive a first episode of SBP or with a low protein concentration in the ascitic fluid require an antibiotic prophylaxis. The prognosis of untreated HRS type 1 is grave. Treatment consists of a combination of terlipressin and albumin. Hemodialysis might serve in selected patients as a bridging therapy to liver transplantation. Liver transplantation should be considered in all patients with ascites and liver cirrhosis.

Abstract
INTRODUCTION Ascites is a common complication of advanced cirrhosis that has a significant negative impact on survival. This review updates the reader on the medical management of ascites. AREAS COVERED This review explores the pathophysiology of ascites formation in cirrhosis; the current mainstays of medical management (treating the underlying cause of cirrhosis, avoiding nephrotoxic agents, sodium restriction, and combination diuretic therapy); potential novel agents, such as vasoconstrictors and vaptans; and albumin infusions. The literature research covers all aspects of medical management of ascites from the English literature, concentrating on publications from the past 10 years. It provides a thorough understanding of how the correction of pathophysiology of ascites formation helps to improve ascites; knowledge on the monitoring of patients with cirrhosis and ascites receiving medical management, and on prophylaxis against potentially life-threatening complication such as spontaneous bacterial peritonitis; and potential new treatments for ascites. EXPERT OPINION Management of patients with cirrhosis and ascites requires careful attention to fluid and electrolyte balance and avoidance of complications. Recognition of refractory ascites allows for the use of second-line treatments. All patients with cirrhosis and ascites should be considered for liver transplantation.

Abstract
Ascites, hepatic encephalopathy and variceal hemorrhage are three major complications of portal hypertension. The diagnostic evaluation of ascites involves an assessment of its etiology by determining the serum-ascites albumin gradient and the exclusion of spontaneous bacterial peritonitis. Ascites is primarily related to an inability to excrete an adequate amount of sodium into urine, leading to a positive sodium balance. Sodium restriction and diuretic therapy are keys of ascites control. But, with the case of refractory ascites, large volume paracentesis and transjugular portosystemic shunts are required. In hepatorenal syndrome, splanchnic vasodilatation with reduction in effective arterial volume causes intense renal vasoconstriction. Splanchnic and/or peripheral vasoconstrictors with albumin infusion, and renal replacement therapy are only bridging therapy. Liver transplantation is the only definitive modality of improving the long term prognosis.

Abstract
OBJECTIVE To review relevant studies for both primary and secondary antibiotic prophylaxis of spontaneous bacterial peritonitis (SBP) in patients with cirrhosis without gastrointestinal bleeding. DATA SOURCES A search of PubMed (1980-July 2010) was conducted using the terms prophylaxis, SBP, and antibiotics. A manual review of bibliographies was conducted for inclusion of relevant articles. STUDY SELECTION AND DATA EXTRACTION Prospective studies and meta-analyses published in English were included. DATA SYNTHESIS Ten trials and 3 meta-analyses were included. Of the 10 trials, 2 examined the use of secondary prophylaxis for prevention of subsequent episodes of SBP, 4 examined the use of primary prophylaxis to prevent an initial SBP episode, and 4 examined the use of antibiotic prophylaxis in a mixed population. Seven trials evaluated the use of an antibiotic compared to placebo or no treatment. Only 1 trial evaluated norfloxacin versus trimethoprim/sulfamethoxazole. Trial duration varied from 24 days to 12 months. In general, trials examining norfloxacin as secondary prophylaxis found significantly decreased occurrence of SBP but no significant difference in mortality rates. Primary prophylaxis studies found no significant difference in the incidence of infections, including SBP, with norfloxacin or ciprofloxacin treatment but significantly lower incidence of gram-negative infections. Mixed population studies found a significantly decreased incidence of SBP but no significant difference in mortality. In the 3 meta-analyses, a significant decrease in mortality and an overall decrease in SBP incidence in the treatment groups were noted. CONCLUSIONS Based on currently available data, the use of prophylactic antibiotic therapy is warranted for the prevention of recurrent SBP in patients with cirrhosis and ascites. In patients with low ascetic fluid protein and at least 1 more risk factor, primary prophylaxis may be considered. Further studies with improved methodology are needed to determine whether prophylactic antibiotic therapy has an impact on mortality.
