Abstract
Liver cirrhosis is a chronic disease that can be complicated by episodes of decompensation such as variceal bleeding, hepatic encephalopathy, ascites, and jaundice, with subsequent increased mortality. Infections are also among the most common complications in cirrhotic patients, mostly due to a defect in immunosurveillance. Among them, one of the most frequent is spontaneous bacterial peritonitis (SBP), defined as the primary infection of ascitic fluid without other abdominal foci. SBP is mainly induced by Gram-negative bacteria living in the intestinal tract, and translocating through the intestinal barrier, which in cirrhotic patients is defective and more permeable. Moreover, in cirrhotic patients, the intestinal microbiota shows an altered composition, poor in beneficial elements and enriched in potentially pathogenic ones. This condition further promotes the development of leaky gut and increases the risk of SBP. The first-line treatment of SBP is antibiotic therapy; however, the antibiotics used have a broad spectrum of action and may adversely affect the composition of the gut microbiota, worsening dysbiosis. For this reason, the future goal is to use new therapeutic agents that act primarily on the gut microbiota, selectively modulating it, or on the intestinal barrier, reducing its permeability. In this review, we aim to describe the reciprocal relationship between gut microbiota and SBP, focusing on pathogenetic aspects but also on new future therapies.

Abstract
Leaky gut syndrome is a medical condition characterized by intestinal hyperpermeability. Since the intestinal barrier is one of the essential components maintaining homeostasis along the gastrointestinal tract, loss of its integrity due to changes in bacterial composition, decreased expression levels of tight junction proteins, and increased concentration of pro-inflammatory cytokines may lead to intestinal hyperpermeability followed by the development of gastrointestinal and non-gastrointestinal diseases. Translocation of microorganisms and their toxic metabolites beyond the gastrointestinal tract is one of the fallouts of the leaky gut syndrome. The presence of intestinal bacteria in sterile tissues and distant organs may cause damage due to chronic inflammation and progression of disorders, including inflammatory bowel diseases, liver cirrhosis, and acute pancreatitis. Currently, there are no medical guidelines for the treatment or prevention of bacterial translocation in patients with the leaky gut syndrome; however, several studies suggest that dietary intervention can improve barrier function and restrict bacteria invasion. This review contains current literature data concerning the influence of diet, dietary supplements, probiotics, and drugs on intestinal permeability and bacterial translocation.

Abstract
INTRODUCTION: With the emergence of multidrug-resistant organisms, the efficacy of antibiotic prophylaxis to prevent spontaneous bacterial peritonitis (SBP) has been debated. The aim of this study was to assess factors impacting effectiveness of SBP prophylaxis. METHODS: We searched PubMed, Embase, and the Cochrane Registry from inception to May 2019 to identify randomized controlled trials of patients with liver cirrhosis that assessed SBP occurrence/recurrence during antibiotic prophylaxis with the common antibiotic agents. Network meta-analysis was performed, pooling data with regard to incidence rate ratios (IRRs) of SBP, death, or extraperitoneal infections. RESULTS: Overall, 1,626 patients in 12 randomized controlled trials were included. During primary prophylaxis, the incidence rate of SBP and death in the norfloxacin-treated patients was 0.117 and 0.438 per patient-year, respectively, and IRRs of placebo vs norfloxacin were significantly higher (IRR 5.35, 95% confidence interval 1.99–14.38, P = 0.0009 for SBP and IRR 2.04, 95% confidence interval 1.20–3.44, P = 0.008 for death). The efficacy of norfloxacin to prevent SBP, but not death, decreased over time (annual percent change from 1992 to 2015 8.2%, P = 0.019), The positive treatment effect was lower in studies including patients with increased ascites protein (P = 0.021) or exceedingly high serum bilirubin (P = 0.012) levels. Norfloxacin was not superior to other antibiotics. The incidence rate of SBP was 2.5-fold higher in patients treated with norfloxacin as secondary compared with primary prophylaxis. No significant differences between treatment designs were observed in secondary prophylaxis. DISCUSSION: Norfloxacin remained superior to placebo in preventing SBP, yet the efficacy to prevent SBP, not death, decreased over time. Further studies to understand this phenomenon are urgently needed.

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
OBJECTIVES For the prevention of spontaneous bacterial peritonitis (SBP) in cirrhotic patients with ascites, norfloxacin 400 mg per day is recommended as a standard regimen. This study aims to investigate whether ciprofloxacin once weekly administration is not inferior to norfloxacin once daily administration for the prevention of SBP. METHODS This is an investigator-initiated open-label randomized controlled trial conducted at seven tertiary hospitals in South Korea. Liver cirrhosis patients with ascites were screened, and enrolled in this randomized controlled trial if ascitic protein ≤1.5 g/dL or the presence of history of SBP. Ascitic polymorphonucleated cell count needed to be <250/mm3. Patients were randomly assigned into norfloxacin daily or ciprofloxacin weekly group, and followed-up for 12 months. Primary endpoint was the prevention of SBP. RESULTS One hundred twenty-four patients met enrollment criteria and were assigned into each group by 1:1 ratio (62:62). Seven patients in the norfloxacin group and five patients in the ciprofloxacin group were lost to follow-up. SBP developed in four patients (4/55) and in three patients (3/57) in each group, respectively (7.3% vs. 5.3%, P = 0.712). The transplant-free survival rates at 1 year were comparable between the groups (72.7% vs. 73.7%, P = 0.970). Incidence of infectious complication, hepatorenal syndrome, hepatic encephalopathy, and variceal bleeding rates were not significantly different (all P = ns). The factors related to survival were models representing underlying liver function. CONCLUSION Once weekly ciprofloxacin was as effective as daily norfloxacin for the prevention of SBP in cirrhotic patients with ascites.

Abstract
Liver cirrhosis is a worldwide public health problem, and patients with this disease are at high risk of developing complications, bacterial translocation from the intestinal lumen to the mesenteric nodes, and systemic circulation, resulting in the development of severe complications related to high mortality rate. The intestinal barrier is a structure with a physical and biochemical activity to maintain balance between the external environment, including bacteria and their products, and the internal environment. Patients with liver cirrhosis develop a series of alterations in different components of the intestinal barrier directly associated with the severity of liver disease that finally increased intestinal permeability. A "leaky gut" is an effect produced by damaged intestinal barrier; alterations in the function of tight junction proteins are related to bacterial translocation and their products. Instead, increasing serum proinflammatory cytokines and hemodynamics modification, which results in the appearance of complications of liver cirrhosis such as hepatic encephalopathy, variceal hemorrhage, bacterial spontaneous peritonitis, and hepatorenal syndrome. The intestinal microbiota plays a fundamental role in maintaining the proper function of the intestinal barrier; bacterial overgrowth and dysbiosis are two phenomena often present in people with liver cirrhosis favoring bacterial translocation. Increased intestinal permeability has an important role in the genesis of these complications, and treating it could be the base for prevention and partial treatment of these complications.

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 Bacterial infections are a serious complication of cirrhosis, as they can lead to decompensation, multiple organ failure, and/or death. Preventing infections is therefore very relevant. Because gut bacterial translocation is their main pathogenic mechanism, prevention of infections is mostly based on the use of orally administered poorly absorbed antibiotics such as norfloxacin (selective intestinal decontamination). However, antibiotic prophylaxis leads to antibiotic resistance, limiting therapy and increasing morbidity and mortality. Prevention of bacterial infections in cirrhosis should therefore move away from antibiotics. AREAS COVERED This review focuses on various potentially novel methods to prevent infections in cirrhosis focusing on non-antibiotic strategies. The use of probiotics, nonselective intestinal decontamination with rifaximin, prokinetics and beta-blockers or fecal microbiota transplant as means of targeting altered gut microbiota, bile acids and FXR agonists are all potential alternatives to selective intestinal decontamination. Prokinetics and beta-blockers can improve intestinal motility, while bile acids and FXR agonists help by improving the intestinal barrier. Finally, granulocyte colony stimulating factor (G-CSF) and statins are emerging therapeutic strategies that may improve immune dysfunction in cirrhosis. EXPERT OPINION Evidence for these strategies has been restricted to animal studies and proof-of concept studies but we expect this to change in coming years.

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

Abstract
AIM : Although numerous animal studies suggest that probiotic therapy has beneficial effects in various liver diseases, the evidence for beneficial effects in human liver disease is controversial. This study was carried out to investigate the efficacy of probiotic therapy in alleviating small intestinal bacterial overgrowth (SIBO) and permeability in chronic liver disease. METHODS Fifty-three patients with chronic liver disease were randomized to either probiotic therapy or placebo. Six bacterial species were used: Bifidobacterium bifidum, Bifidobacterium lactis, Bifidobacterium longum, Lactobacillus acidophilus, Lactobacillus rhamnosus, and Streptococcus thermophilus. After 4 weeks, changes in the composition of fecal bacteria, SIBO, intestinal permeability, and clinical symptoms were examined. RESULTS Three of the six probiotic species, B. lactis, L. rhamnosus, and L. acidophilus, increased in the feces of the probiotic therapy group (P<0.001), whereas there was no change in fecal microbiota in the placebo group. SIBO disappeared in many individuals of the probiotic therapy group, but none in the placebo (24 vs. 0%, P<0.05). General gastrointestinal symptoms also improved more in the probiotic group and improvement in intestinal permeability was slightly but not significantly more frequent in the probiotic arm than the placebo arm (50 vs. 31.3%, P=0.248). Numbers of lactobacilli in stool were correlated negatively with intestinal permeability (P for trend<0.05). Liver chemistry did not improve significantly in either group. CONCLUSIONS We conclude that short-term probiotic administration in chronic liver disease is effective in alleviating SIBO and clinical symptoms, but ineffective in improving intestinal permeability and liver function.

Abstract
AIM: To investigate the effect of gastric acid suppressants and prokinetics on peritonitis development in peritoneal dialysis (PD) patients.
METHODS: This was a single-center, retrospective study. The medical records of 398 PD patients were collected from January 2000 to September 2012 and analyzed to compare patients with at least one episode of peritonitis (peritonitis group, group A) to patients who never had peritonitis (no peritonitis group, group B). All peritonitis episodes were analyzed to compare peritonitis caused by enteric organisms and peritonitis caused by non-enteric organisms.
RESULTS: Among the 120 patients who met the inclusion criteria, 61 patients had at least one episode of peritonitis and 59 patients never experienced peritonitis. Twenty-four of 61 patients (39.3%) in group A and 15 of 59 patients (25.4%) in group B used gastric acid suppressants. Only the use of H2-blocker (H2B) was associated with an increased risk of PD-related peritonitis; the use of proton pump inhibitors, other antacids, and prokinetics was not found to be a significant risk factor for PD-related peritonitis. A total of 81 episodes of peritonitis were divided into enteric peritonitis (EP) or non-enteric peritonitis, depending on the causative organism, and gastric acid suppressants and prokinetics did not increase the risk of EP in PD patients.
CONCLUSION: The use of H2B showed a trend for an increased risk of overall PD-related peritonitis, although further studies are required to clarify the effects of drugs on PD-related peritonitis.

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
Patients with cirrhosis are immunocompromised and susceptible to infections. Although detection and treatment of spontaneous bacterial peritonitis (SBP) have improved, overall survival rates have not increased greatly in recent decades-infection still increases mortality 4-fold among patients with cirrhosis. Hospitalized patients with cirrhosis have the highest risk of developing infections, especially patients with gastrointestinal (GI) hemorrhage. Bacterial infections occur in 32% to 34% of patients with cirrhosis who are admitted to the hospital and 45% of patients with GI hemorrhage. These rates are much higher than the overall rate of infection in hospitalized patients (5%-7%). The most common are SBP (25% of infections), urinary tract infection (20%), and pneumonia (15%). Bacterial overgrowth and translocation from the GI tract are important steps in the pathogenesis of SBP and bacteremia-these processes increase levels of endotoxins and cytokines that induce the inflammatory response and can lead to septic shock, multiorgan dysfunction, and death. A number of other bacterial and fungal pathogens are more common and virulent in patients with cirrhosis than in the overall population. We review the pathogenesis of infections in these patients, along with diagnostic and management strategies.

Abstract
BACKGROUND Several large studies revealed that selective intestinal decontamination (SID) prevented recurrence of spontaneous bacterial peritonitis (SBP) in cirrhotic patients. Nonetheless, there are no definitive patient selection parameters identifying who would benefit from SID. AIMS To investigate long-term outcomes in cirrhosis patients with recurrence of SBP and to identify predictive factors for SBP recurrence. METHODS We retrospectively studied 146 cirrhosis patients diagnosed with a first episode of SBP from 2005 to 2006. Of these, 89 patients survived; the survivors were divided into two groups based on recurrence and non-recurrence of SBP, and clinical parameters, survival time and cause of death were analysed. RESULTS The in-hospital mortality was 39% (57/146). The SBP recurrence rate was 42.7% (38/89). The survival rate between patients with recurrent SBP and those without recurrence did not differ (P=0.092). Sepsis was the major cause of death in the recurrent SBP group, but not in the non-recurrent group. Serum albumin level before discharge and β-blocker use between the two groups differed significantly (P<0.0001). Using the cut-off point for serum albumin level before discharge of 2.85 g/dl as a predictor for recurrence of SBP, the sensitivity was 70.2% and the specificity was 76.3%. Furthermore, long-term survival of the group with high albumin before discharge was better than that of the corresponding group with low albumin (P=0.007). CONCLUSION Spontaneous bacterial peritonitis was associated with high sepsis-related mortality in cirrhotic patients. Serum albumin before discharge was a useful single parameter to predict the recurrence of SBP and long-term survival.

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.

Abstract
OBJECTIVES Bacterial translocation seems to precede the occurrence of overt bacterial infection in patients with cirrhosis. The presence of bacterial DNA in blood and ascites correlates with bacterial translocation and is frequent in patients with advanced cirrhosis without overt infection. Our aim was to search for bacterial DNA in patients with cirrhosis both with and without ascites, and to study its correlation with abnormal intestinal motility or permeability and the presence of bacterial overgrowth. METHODS Blood and ascites samples were obtained on day 1, and blood samples were taken twice a day for the following 3 days. Bacterial DNA was assayed by polymerase chain reaction using universal primers for rRNA 16 s. Oro-caecal transit time and bacterial overgrowth were assessed with Lactulose H(2) breath testing. Intestinal permeability was assessed by determining urinary lactulose and mannitol excretion with high performance liquid chromatography. RESULTS We studied seven patients (six were male, age range was 42-78 years). Aetiology was alcohol in four, HCV in two, HBV in one; ascites was present in four and Child-Pugh grade was A in four and B in three. All patients had increased intestinal permeability, six had decreased transit time and one had bacterial overgrowth. In only one patient (with ascites), polymerase chain reaction was positive for bacterial DNA both in ascites and serum for all 4 days on which samples were taken. CONCLUSION Increased intestinal permeability and abnormal motility were frequent without evidence of bacterial translocation in cirrhosis even without ascites. They are likely to be facilitators for bacterial translocation and thus precede it.

Abstract
Spontaneous bacterial peritonitis (SBP), a common complication of cirrhosis of liver, might result from translocation of bacteria from the small bowel. However, there is scanty data on frequency of small intestinal bacterial overgrowth (SIBO) in patients with cirrhosis of the liver. There are no data on SIBO in patients with extra-hepatic portal venous obstruction (EHPVO) in the literature. A total of 174 patients with cirrhosis of the liver, 28 with EHPVO and 51 healthy controls were studied for SIBO using glucose hydrogen breath test (GHBT). Persistent rise in breath hydrogen 12 ppm above basal (at least two readings) was considered diagnostic of SIBO. Of 174 patients (age 47.2 +/- 11.9 years, 80.5% male) with cirrhosis due to various causes, 67 (38.5%) were in Child's class A, 70 (40.2%) class B and 37 (21.7%) class C. Of the 174 patients with cirrhosis, 42 (24.14%) had SIBO as compared to 1 of 51 (1.9%) healthy controls (P < 0.0001). Patients with EHPVO had similar frequency of SIBO compared to healthy controls [2/28 (7.14%) vs 1/51 (1.97%), P = ns]. Frequency of SIBO in Child's A, B and C was comparable [13 (18.6%) vs 16 (23.9%) and 13 (35.1%), respectively; P = ns]. Presence of SIBO were not related to ascites, etiology of cirrhosis, and degree of liver dysfunction. SIBO is common in patients with cirrhosis of the liver. Patients with EHPVO do not have higher frequency of SIBO than healthy subjects. SIBO in cirrhosis is not related to the degree of derangement in liver function or of portal hypertension.

Abstract
BACKGROUND Spontaneous bacterial peritonitis is frequent among cirrhotic patients, associated with significant morbidity and mortality. Selective intestinal decontamination employing antibiotics is a proposed prophylactic measure. While data regarding this modality among cirrhotic patients with gastrointestinal bleeding exist, there is insufficient data synthesis regarding cirrhotic patients with ascites and no gastrointestinal bleeding. OBJECTIVES To assess whether antibiotic prophylaxis decreases spontaneous bacterial peritonitis and mortality among cirrhotic patients with ascites and no gastrointestinal bleeding. SEARCH STRATEGY We identified relevant randomised trials by searching trial registries of The Cochrane Hepato-Biliary Group and The Cochrane Collaboration, medical literature search engines, and reviewing all literature we found on the topic until February 2009. SELECTION CRITERIA We searched for randomised clinical trials assessing prophylactic treatment among adult cirrhotic patients with ascites and no gastrointestinal bleeding, comparing antibiotic therapy with no intervention, placebo, or with another antibiotic regimen. DATA COLLECTION AND ANALYSIS Three independent authors searched for and collected the trials and extracted relevant data. Four other independent authors validated the findings and assessed them. The studies were assessed for design, patient and intervention characteristics, and quality. A meta-analysis was performed to estimate measures of association between antibiotic prophylaxis and spontaneous bacterial peritonitis or mortality. MAIN RESULTS Nine trials were included in the review. Seven trials, comparing antibiotics to placebo or no treatment, were meta-analysed. Systematic bias in design or publication is suggested by trial results. The randomisation results suggest that the probability that true randomisation took place in all trials is very small and the report of most trials regarding design was poor. The proportion of participants with spontaneous bacterial peritonitis varied between the trials from 15% to 50%. The calculated relative risks (95% confidence interval) of spontaneous bacterial peritonitis and mortality among patients treated with antibiotics compared with no treatment/placebo were 0.20 (0.11 to 0.37) and 0.61 (0.43 to 0.87). There were very few reports of adverse events. AUTHORS' CONCLUSIONS The pooled estimates suggest that antibiotic prophylaxis might be prudent among cirrhotic patients with ascites and no gastrointestinal bleeding. However, poor trial methodology and report coupled with findings suggesting systematic bias in publication and design reflect the fragility of these findings. Potential hazard to society and the patients themselves from resistant pathogens should be considered when promoting long-lasting antibiotic prophylaxis. It seems that recommending antibiotic prophylaxis is still far from being a substantiated prevention strategy. Trials of better design, well reported, and of longer follow-up are greatly needed.

Abstract
Prokinetic agents are effective not only for disease of the gastrointestinal (GI) tract but also for those external to the GI tract such as the central nervous system, and the respiratory, urologic, and metabolic organs. This article reviews the effectiveness of prokinetic agents against diseases external to the GI tract. Studies were identified by computerized and manual searches of the available literature. A Medline search was performed (1975-July, 2008) using the following medical subject headings: prokinetic agent, metoclopramide, domperidone, trimebutine, cisapride, itopride, mosapride, tegaserod, and human. The identified diseases for which prokinetic agents may be effective are various: bronchial asthma, chronic cough, hiccup, spontaneous bacterial peritonitis, cholelithiasis, diabetes mellitus, acute migraine, Parkinson's disease, anorexia nervosa, Tourette's disorder, urologic sequelae of spinal cord injury and of radical hysterectomy for cervical cancer, laryngeal dysfunction and so on. These agents are also useful for prevention of aspiration pneumonia during anesthesia, and in tube-fed patients. Prokinetic agents should be a valuable addition to our currently limited pharmacological armamentarium not only for functional bowel disease, but also for diseases external to the GI tract.

Abstract
OBJECTIVES Host factors and bacterial virulence determinants may play a role in Escherichia coli (E. coli) spontaneous bacterial peritonitis. We evaluated the importance of these factors in the emergence of fluoroquinolone-resistant strains and outcome in cirrhotic patients with E. coli spontaneous bacterial peritonitis. METHODS E. coli spontaneous bacterial peritonitis was detected in a 2-year period in three tertiary hospitals. Clinical and bacteriological data were obtained. Phylogenetic group and 15 virulence genes of E. coli strains were analyzed by polymerase gene reaction and compared with 50 isolates from pyelonephritis patients. RESULTS Forty-seven E. coli spontaneous bacterial peritonitis patients were identified, 18 (38%) were fluoroquinolone-resistant, a 12% increase compared with our earlier series from 1997 to 2002. Fluoroquinolone resistance was associated with norfloxacin prophylaxis, increased resistance to trimethoprim-sulfamethoxazole and cefotaxime, and less bacterial virulence, as demonstrated by a higher prevalence of 'nonpathogenic' phylogenetic groups A+B1 (56 vs. 28%; P=0.04) and lower virulence scores in fluoroquinolone-resistant E. coli compared with fluoroquinolone-susceptible E. coli. E. coli strains from cirrhotic patients belonged more frequently to 'nonpathogenic' phylogenetic groups A+B1, had fewer virulence factors and higher rates of fluoroquinolone resistance than isolates from pyelonephytis patients. Immunosuppression was independently associated with in-hospital and 3-month mortality. Bacterial virulence factors were unrelated to mortality. CONCLUSION Fluoroquinolone-resistant E. coli spontaneous bacterial peritonitis prevalence is increasing because of norfloxacin prophylaxis. Strains from peritonitis are less virulent than strains from pyelonephritis because of a higher prevalence of A+B1 phylogeny and quinolone resistance. Mortality is related to immunosuppression, but not to bacterial virulence factors.

Abstract
BACKGROUND Consideration of the prognosis of patients with liver cirrhosis is important when determining the appropriate timing of liver transplantation. Especially in Japan, where 99% of liver transplants are from living donors, timing is very important not only for the patient but also for the family, who need time to consider the various factors involved in living donations. METHODS To clarify the applicability of the Model for End-Stage Liver Disease (MELD) score in Japanese patients with cirrhosis, changes in the MELD score over 24 months were reviewed in 79 patients with cirrhosis who subsequently died of liver failure (n=33) or who survived 24 months (n=46). All patients had Child class B or C cirrhosis at the start of follow-up. We also compared their survival with that of 30 patients treated by living donor liver transplantation (LDLT) in our institute to determine the proper timing of transplantation in patients with cirrhosis. RESULTS Significant stratification of survival curves was observed for MELD scores of <12, 12-15, 15-18, and >18 (P=0.0018). A significant survival benefit of LDLT was observed in patients with MELD score >or=15 (P=0.0181), and significantly more risk with transplantation was observed in those with MELD score <15 compared with that of patients in whom the disease followed its natural course (P=0.0168). CONCLUSIONS MELD score is useful for predicting 1-year survival in Japanese patients with cirrhosis. MELD scores of 15 had discriminatory value for indicating a survival benefit to be gained by liver transplantation and thus can be used to help patients and their families by identifying patients who would benefit from LDLT.

Abstract
BACKGROUND & AIMS Norfloxacin is highly effective in preventing spontaneous bacterial peritonitis recurrence in cirrhosis, but its role in the primary prevention of this complication is uncertain. METHODS Patients with cirrhosis and low protein ascitic levels (<15 g/L) with advanced liver failure (Child-Pugh score > or = 9 points with serum bilirubin level > or = 3 mg/dL) or impaired renal function (serum creatinine level > or = 1.2 mg/dL, blood urea nitrogen level > or = 25 mg/dL, or serum sodium level < or = 130 mEq/L) were included in a randomized controlled trial aimed at comparing norfloxacin (35 patients) vs placebo (33 patients) in the primary prophylaxis of spontaneous bacterial peritonitis. The main end points of the trial were 3-month and 1-year probability of survival. Secondary end points were 1-year probability of development of spontaneous bacterial peritonitis and hepatorenal syndrome. RESULTS Norfloxacin administration reduced the 1-year probability of developing spontaneous bacterial peritonitis (7% vs 61%, P < .001) and hepatorenal syndrome (28% vs 41%, P = .02), and improved the 3-month (94% vs 62%, P = .003) and the 1-year (60% vs 48%, P = .05) probability of survival compared with placebo. CONCLUSIONS Primary prophylaxis with norfloxacin has a great impact in the clinical course of patients with advanced cirrhosis. It reduces the incidence of spontaneous bacterial peritonitis, delays the development of hepatorenal syndrome, and improves survival.

Abstract
Cirrhosis is the twelfth commonest cause of death in the United States, with more than 27,000 deaths and more than 421,000 hospitalizations annually. Currently, there are more than 17,000 patients awaiting liver transplantation in the United States across the 11 United Network for Organ Sharing regions. Approximately 10% of such patients will die awaiting transplantation.
