Abstract
The incidence of chronic liver disease is on the rise. One of the primary causes of hospital admissions for patients with cirrhosis is hepatic encephalopathy (HE), a debilitating neurological complication. HE is defined as a reversible syndrome, yet there is growing evidence stating that, under certain conditions, HE is associated with permanent neuronal injury and irreversibility. The pathophysiology of HE primarily implicates a strong role for hyperammonemia, but it is believed other pathogenic factors are involved. The fibrotic scarring of the liver during the progression of chronic liver disease (cirrhosis) consequently leads to increased hepatic resistance and circulatory anomalies characterized by portal hypertension, hyperdynamic circulatory state and systemic hypotension. The possible repercussions of these circulatory anomalies on brain perfusion, including impaired cerebral blood flow (CBF) autoregulation, could be implicated in the development of HE and/or permanent brain injury. Furthermore, hypotensive insults incurring during gastrointestinal bleed, infection, or liver transplantation may also trigger or exacerbate brain dysfunction and cell damage. This review will focus on the role of hypotension in the onset of HE as well as in the occurrence of neuronal cell loss in cirrhosis.

Kim SH, Kim YK. Emergency, ABO-Incompatible Living Donor Liver Re-Transplantation for Graft Failure Complicated by Pneumonia-Associated Sepsis. J Clin Med 2023; 12:jcm12031110. [PMID: 36769757 PMCID: PMC9917672 DOI: 10.3390/jcm12031110] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/20/2022] [Revised: 01/25/2023] [Accepted: 01/29/2023] [Indexed: 02/05/2023] Open
Abstract
Although liver re-transplantation is the only therapeutic option for acute and chronic graft failure, few studies have addressed the use of ABO-incompatible living donors in the emergency setting. Here, based on our experience, we report a successful case of emergency, ABO-incompatible, adult-to-adult, living donor liver re-transplantation (LDLT) for late graft failure from chronic rejection complicated by pneumonia-related sepsis. A fifty-five-year-old man had undergone LDLT for hepatocellular carcinoma accompanied by hepatitis C virus (HCV)-related cirrhosis in 30 September 2013. The voluntary donor was his 56-year-old wife, who was also a carrier of HCV. The donor and recipient blood types were the same: O and Rh positive. She underwent a right hepatectomy and was discharged on postoperative day (POD) seven. The patient was also discharged without complications on POD eleven and was followed up with on an outpatient basis. Abdominal distension and jaundice were developed at 6 months after LDLT, when the serum total bilirubin level was 2.7 mg/dL. The serum total bilirubin levels increased rapidly to 22.9 mg/dL over the next 4 months. Chronic rejection was diagnosed via liver biopsy. On 3 October 2014, he developed pneumonia-related sepsis and showed the progressive deterioration of liver function. Liver re-transplantation using the right liver from his ABO-incompatible, 20-year-old nephew was performed as an emergency in 15 October 2014. The donor blood type was A and Rh positive. The resection of the failed graft and the implantation of a new graft was performed by the intragraft dissection technique to re-use previously transplanted graft vessels in order to cope with severe adhesions. The recipient went through a gradual recovery process and was finally discharged on POD 50 with normal liver function, while the donor had an uneventful recovery and was discharged on POD 7. Biloma due to bile leak was detected three months after re-transplantation and was cured by percutaneous interventional procedures. Since then, the postoperative course has been event-free at regular outpatient follow-ups. The patient has so far had normal laboratory findings and no signs of complications. It has been 98 months since the re-transplantation, and the recipient and two donors are still in good condition with normal liver function, having complete satisfaction with the results obtained from this re-transplantation. In conclusion, long-term, satisfactory outcomes can be achieved in emergency, ABO-incompatible, adult-to-adult, living donor liver re-transplantation for graft failure complicated by pneumonia-related sepsis in selected patients.

Pyogenic spinal infections in patients with chronic liver disease: illustrative case and systematic review. JOURNAL OF NEUROSURGERY: CASE LESSONS 2022; 4:CASE22222. [PMID: 36046268 PMCID: PMC9329861 DOI: 10.3171/case22222] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 05/18/2022] [Accepted: 06/13/2022] [Indexed: 11/06/2022]
Abstract
BACKGROUND
Pyogenic spinal infections (PSIs) are a group of uncommon but serious infectious diseases that are characterized by inflammation of the endplate–disc unit. PSIs are considered more prevalent and aggressive among patients with chronic immunocompromised states. Association between PSIs and liver disease has not been systematically analyzed. The authors performed a systematic review to study baseline characteristics, clinical presentation, and mortality of patients with PSI in the setting of chronic liver disease.
OBSERVATIONS
The authors presented the case of a 72-year-old female patient with chronic liver disease who presented with severe low back pain and bilateral lower weakness. Imaging studies showed T10–11 spondylodiscitis. The patient received decompression and fusion surgery with partial neurological improvement. The authors performed a systematic literature search of spondylodiscitis and liver disease, and eight published articles met the studies inclusion and exclusion criteria. These studies featured a total of 144 patients, of whom 129 met inclusion criteria (mean age, 60.5 years, range 40 to 83 years; 62% males). Lumbar infection was the most common report (67%), with Staphylococcus aureus (48%) as the main causative microorganism. Neurological compromise was present in 69% of patients. Surgical intervention occurred in 70.5% of patients, and the average duration of antibiotic treatment was 69.4 days. Postoperative complication rate was 28.5%, with a 30- and 90-day mortality of 17.2% and 24.8%, respectively.
LESSONS
Pyogenic spondylodiscitis in patients with liver disease was associated with a high rate of neurological compromise, postoperative complications, and mortality.

Abstract
Abstract
End-stage liver disease (ESLD) is a life-threatening clinical syndrome that markedly increases mortality in patients with infections. In patients with ESLD, infections can induce or aggravate the occurrence of liver decompensation. Consequently, infections are among the most common complications of disease progression. There is a lack of working procedure for early diagnosis and appropriate management for patients with ESLD complicated by infections as well as local and international guidelines or consensus. This consensus assembled up-to-date knowledge and experience across Chinese colleagues, providing data on principles as well as working procedures for the diagnosis and treatment of patients with ESLD complicated by infections.

Abstract
INTRODUCTION Presepsin (or sCD14) has been identified as a protein whose levels increase specifically in the blood of patients with bacterial infections. In this study, we evaluated the clinical performance of sCD14 and its usefulness in the early diagnosis of bacterial infection in decompensated cirrhotic patients. MATERIALS Seventy patients were enrolled in this study. The mean age of patients was 49.5 years, and 21 were women and 49 men. The heparinized whole blood for the PATHFAST test was used in the evaluation of bacterial infection (T0). The test was repeated after 48 hours (T1); at 96 hours (T2); at 144 hours (T3); then at 15 days (T4) to monitor the clinical responses to therapeutic interventions. RESULTS Forty-nine patients tested positive for sCD14. The mean sCD14 level was 1854 ± 1744 pg/mL. Microbiological findings confirmed the presence of bacterial infections within 84 ± 4.8 h from enrollment in all 49 positive patients. Thirty-eight patients were considered responders to empirical antibiotic therapy with a decrease of presepsin at the different time points, while an increased level of sCD14 was highlighted in 11 patients. When the test was performed, 45% of the patients showed no signs or symptoms of bacterial infection. At 30 days of follow-up 43 patients survived, and 6 patients died from septic shock. CONCLUSIONS The PATHFAST test highlighted the presence of infection in a very short time (15 minutes), and the presepsin could be considered an early biomarker in patients with cirrhosis. A greater number of patients are necessary to confirm these data.

Abstract
Ascitic fluid infection is a major cause of morbidity and mortality in cirrhotic patients, requiring early diagnosis and therapy. We aimed to determine predictors of ascitic fluid infection in children with chronic liver disease. The study included 45 children with chronic liver disease and ascites who underwent 66 paracentesis procedures. Full history taking and clinical examination of all patients were obtained including fever, abdominal pain and tenderness and respiratory distress. Investigations included: complete blood count, C-reactive protein, full liver function tests, ascitic fluid biochemical analysis, cell count and culture. Our results showed that patients' ages ranged between 3 months to 12 years. Prevalence of ascitic fluid infection was 33.3%. Gram-positive bacteria were identified in six cases, and Gram-negative bacteria in five. Fever and abdominal pain were significantly more associated with infected ascites (p value = 0.004, 0.006). Patients with ascitic fluid infection had statistically significant elevated absolute neutrophilic count and C-reactive protein. Logistic regression analysis showed that fever, abdominal pain, elevated absolute neutrophilic count and positive C-reactive protein are independent predictors of ascitic fluid infection. Fever, elevated absolute neutrophilic count and positive C-reactive protein raise the probability of ascitic fluid infection by 3.88, 9.15 and 4.48 times respectively. The cut-off value for C-reactive protein for ascitic fluid infection was 7.2 with sensitivity 73% and specificity of 71%. In conclusion, prevalence of ascitic fluid infection in pediatric patients with chronic liver disease and ascites was 33.3%. Fever, abdominal pain, positive C-reactive protein and elevated absolute neutrophilic count are strong predictors of ascitic fluid infection. Therefore an empirical course of first-line antibiotics should be immediately started with presence of any of these predictors after performing ascitic fluid tapping for culture and sensitivity. In absence of these infection parameters, routine ascitic fluid analysis could be spared.

Abstract
Discrimination between urosepsis and febrile urinary tract infections is important in therapeutic decision-making to indicate suitable treatments to avoid sepsis-related organ failure. Accurate diagnosis is time-consuming and susceptible to false-positive results. Moreover, patient responses to urosepsis are complex and varied. Therefore, this study aimed to develop a new, early diagnostic predictor that could discriminate between patients with urosepsis and those with febrile urinary tract infections using a combination of initial procalcitonin and albumin levels.We conducted a retrospective study involving 140 patients with febrile urinary tract infections from January 2013 to December 2017. Univariate and multivariate logistic analyses were performed to identify the independent risk factors for differentiating urosepsis from febrile urinary tract infection. A receiver operating characteristic (ROC) curve analysis was conducted to compare the predictive accuracy of the procalcitonin/albumin ratio.Patients in the urosepsis group had higher procalcitonin/albumin ratios compared to those in the febrile urinary tract infection group [2.254 (0.978, 6.299) vs 0.021 (0.004, 0.095); P < .001]. Based on multivariate logistic analysis, the procalcitonin/albumin ratio [adjusted odds ratio (OR) 1.029, 95% confidence interval (CI) 1.013-1.045, P < .001] was an independent predictor of urosepsis, which allowed for differentiation from patients with febrile urinary tract infections. The area under the ROC curve (AUC) for the procalcitonin/albumin ratio was 0.937 (95% CI, 0.894-0.980); P < .001. The sensitivity and specificity of the procalcitonin/albumin ratio cut-off values (>0.44) were 84.62% and 96.00%, respectively. Moreover, in the subset of 65 patients with urosepsis, the procalcitonin/albumin ratio in the uroseptic shock group was higher than in the group of patients without uroseptic shock [5.46 (1.43, 6.58) vs 1.24 (0.63, 4.38); P = .009].Our study demonstrates that the procalcitonin/albumin ratio is an early diagnostic predictor that can discriminate between urosepsis and febrile urinary tract infection. Additionally, in patients with urosepsis, those with higher procalcitonin/albumin ratios were more prone to uroseptic shock. Our findings suggest that the procalcitonin/albumin ratio is a rapid and relatively low-cost biomarker that can be used in clinical practice.

Abstract
BACKGROUND Spontaneous bacterial peritonitis (SBP) is one of the severe complications of liver cirrhosis. Early detection of high-risk patients is essential for prognostic improvement. The aim of this study is to investigate the predictive factors related to in-hospital mortality in patients with SBP. METHODS This was a retrospective study of 233 SBP patients (181 males, 52 females) who were admitted to four tertiary referral hospitals between August 2002 and February 2013. The patients' laboratory and radiologic data were obtained from medical records. The Child-Turcotte-Pugh (CTP) score and model for end-stage liver disease sodium model (MELD-Na) scores were calculated using the laboratory data recorded at the time of the SBP episode. RESULTS The causes of liver cirrhosis were hepatitis B (44.6%), alcohol (43.8%), hepatitis C (6.0%), and cryptogenic cirrhosis (5.6%). The mean MELD-Na and CTP scores were 27.1 and 10.7, respectively. Thirty-one of the patients (13.3%) died from SBP in hospital. Multivariate analysis revealed that maximum creatinine level during treatment was a statistically significant factor for in-hospital mortality (P = 0.005). The prognostic accuracy of the maximum creatinine level during treatment was 78.0% (P < 0.001). The optimal cutoff point for the maximum serum creatinine was 2 mg/dL (P < 0.001). CONCLUSION The follow-up creatinine level during treatment is an important predictive factor of in-hospital mortality in cirrhotic patients with SBP. Patients with SBP and a serum creatinine level during treatment of ≥ 2.0 mg/dL might have a high risk of in-hospital mortality.

Abstract
Background and Aims: The critically ill patients with liver disease are vulnerable to infections in both community and hospital settings. The nosocomial infections are often caused by multidrug-resistant (MDR) bacteria. The present observational study was conducted to describe the epidemiology, course, and outcome of MDR bacterial infection and identify the risk factors of such infection in critically ill patients with liver disease. Materials and Methods: A retrospective observational study was conducted on 106 consecutive critically patients with liver disease admitted in the Intensive Care Unit between March 2015 and February 2017. The MDR and non-MDR (non-MDR) groups were compared and the risk factors identified by multivariate analysis. Results: Out of the 106 patients enrolled in the study, 23 patients had infections caused by MDR bacteria. The MDR-infected patients had severe liver disease (Child–Pugh score 11 ± 2.3 vs. 7 ± 3.9; P = 0.04), longer duration of antibiotic usage (6 ± 2.7 days vs. 2 ± 1.5 days; P = 0.04), greater use of total parenteral nutrition (TPN) (73.9% vs. 62.6%; P = 0.04), and more concurrent antifungal administration (60.8% vs. 38.5%; P = 0.04). The mortality was higher in MDR group (hazard ratio = 1.86; P < 0.05). The independent predictors of MDR bacterial infection were Child–Pugh score >10, prior carbapenem use, antibiotic use for more than 10 days, TPN use, and concurrent antifungal administration. Conclusion: The study demonstrated a high prevalence of MDR bacterial infection in critically ill patients with a higher mortality over non-MDR bacterial infection and also identified the independent predictors of such infections.

Abstract
AIM Our objective is to study the clinical characteristics of cirrhosis patients with SIRS and investigate its prognostic factors. METHODS We analyzed 285 consecutive patients and their data were evaluated retrospectively. Data were compared in patients with/without SIRS during hospitalization. Univariate and multivariate Cox regression analyses were undertaken separately for cirrhotic patients with SIRS to assess predictive factors for 90-day mortality. RESULTS The mortality was 38.24% (52/136) in patients with SIRS and 6.04% (9/149) in patients without SIRS for 90-day follow-up (P < 0.001). The univariate analysis showed gastrointestinal hemorrhage (P < 0.001), hepatic encephalopathy (P < 0.001), albumin <30 g/L (P < 0.037), creatinine (Cr) >175 µmol/L (P < 0.001), cholinesterase(ChE) activity <3000 U/L (P = 0.019), white blood cell count ≥10 000 (109/L) (P = 0.018), neutrophils ≥80% (P = 0.018), C-reactive protein (CRP) ≥25 mg/L (P < 0.001), procalcitonin ≥1.0 ng/mL (P = 0.007), Child-Pugh class C (P < 0.001), septicemia (P < 0.001), pulmonary infection (P < 0.001),multi-site infection (P = 0.001), acute-on-chronic liver failure (ACLF) (P < 0.001), and advanced hepatocellular carcinoma (HCC) (P < 0.001). In multivariate analysis, only Cr ≥175 µmol/L (hazard ratio [HR] = 2.768; confidence interval [CI], 1.53-5.04; P = 0.001), C-reactive protein ≥25 mg/L (HR = 3.179; CI, 1.772-7.03; P = 0.004), multi-site infection (HR = 19.427; CI, 7.484-50.431; P < 0.001), ACLF (HR = 7.308; CI, 3.048-17.521; P < 0.001), advanced HCC (HR = 2.523; CI, 1.019-6.248; P = 0.045) were independent predictors of 90-day mortality in cirrhotic patients with SIRS. CONCLUSION Cr ≥ 175 µmol/L, CRP ≥ 25 mg/L, multi-site infection, ACLF, and advanced HCC independently predicted a higher rate of 90-day mortality in liver cirrhosis with SIRS.

Abstract
BACKGROUND AND STUDY AIMS Egypt has a high prevalence of hepatitis C virus (HCV) and high morbidity and mortality related to cirrhosis complications. Patients with cirrhosis have an increased risk of bacterial infections. Approximately 25-35% of cirrhotics had infections at admission or during hospitalisation. Data on infection among cirrhotics in Egypt are limited. This study aimed to determine the frequency and microbiological spectrum of infections in cirrhotics and possible risk factors. PATIENTS AND METHODS This study was conducted at a tertiary care hospital. The frequency and microbiological spectrum of infections in cirrhotics were determined. The risk factors for infection were evaluated. RESULTS Of the 100 patients with liver cirrhosis, 61% had infection. Ascitic fluid infection (AFI) was the most common infection (44.3%), followed by urinary tract infection (UTI) (21.3%), respiratory tract infection (RTI) (19.7%), gastroenteritis (6.6%) and skin infection (4.9%). The only risk factor for infection among cirrhotics was diabetes mellitus (DM) (p=0.047). The mean value of mid-arm muscle circumference was significantly lower in the infected group (p=0.047). Among all the cirrhotics, 32.0% had mild to moderate malnutrition and 52.0% had severe malnutrition. The frequency of infection was higher in severe malnutrition (71.2%). CONCLUSIONS The frequency of infections among cirrhotics was 61%. Many types of infections including AFI, RTI, UTI and skin infections were present in patients with liver cirrhosis, but AFI was the most common. DM was the only risk factor for infection, and independent predictors for infection were elevated WBC count and C-reactive protein levels. The frequency of infection was related to the degree of malnutrition.

Abstract
BACKGROUND In contrast to studies evaluating the negative effect of bacterial infections on clinical outcomes after liver transplantation, there is little evidence with regard to pre-transplant bacterial infections. We aimed to investigate the impact of pre-transplant bacterial infections on post-transplant outcomes in patients after liver transplantation. PATIENTS AND METHODS We retrospectively analyzed clinical data from 33 consecutive patients who underwent primary liver transplantations. Patients were divided into two groups based on the occurrence of a bacterial infection within the 30 days before transplantation. RESULTS Of the 33 patients, 23 patients did not have pre-transplant bacterial infections, while 10 patients did have pre-transplant bacterial infections. Pre-transplant bacterial infections were urinary tract infections (n = 4), spontaneous bacterial peritonitis (n = 3), and one each of pneumonia, bacteremia, and cellulitis. There were no differences in clinical characteristics between the two groups. Post-operative clinical outcomes, including post-operative bacterial infection, intensive-care unit re-admission, 30-day re-hospitalization, and 90-day mortality rate were not significantly different between the two groups. The two-year overall survival rate was 76.7% in patients with pre-transplant infections and 80.0% in those without pre-transplant infections. CONCLUSIONS Patients with pre-transplant bacterial infections did not have inferior clinical outcomes, compared with those without pre-transplant bacterial infections.

Abstract
Although blood cultures (BCs) are an important component of diagnostic practice for antibiotic management in patients with pneumonia, several studies have questioned whether they should be performed. The objective of this study was to evaluate the predictive factors of bacteremia and the role of BCs in patients with community-onset pneumonia (community-acquired pneumonia and healthcare-associated pneumonia).This study was retrospectively conducted in patients with community-onset pneumonia who were hospitalized at Jeju National University Hospital between January 2012 and December 2014. A true bacteremia (TB) group and a contaminants or negative bacteremia (CNB) group were classified according to the bacterial growth on the BC media and were investigated for the clinical relevance of the BCs.We enrolled 785 patients; the TB group and the CNB group contained 36 patients (4.5%) and 749 (95.4%) patients, respectively. Only 10 patients (1.2%) required a change in antibiotic therapy based on the BC results (3 patients with an escalation, 7 with a de-escalation). There was no significant difference between the community-acquired pneumonia and the healthcare-associated pneumonia groups with regard to the rate of antibiotic change due to the BC results (1.1% vs 1.4%; P = 0.751). Chronic liver disease (odds ratio [OR] 2.973, 95% confidence interval [CI] 1.099-8.037), a confusion, urea, respiratory rate, blood pressure, age ≥65 (CURB-65) score of 4 to 5 points (OR 3.484, 95% CI 1.304-9.307), and Pneumonia Severity Index (PSI) class V (OR 2.405, 95% CI 1.007-5.743) were independently associated with TB. In patients with PSI class V and a CURB-65 score of 4 to 5 points, the TB group tended to show a higher inhospital mortality rate than the CNB group (50.0% vs 29.4%; P = 0.060, 60.0% vs 42.5%; P = 0.480). The areas under the curve for PSI score and CURB-65 score for predicting TB revealed an increased tendency compared with that of C-reactive protein (0.72, 95% CI 0.630-0.809; and 0.72, 95% CI 0.622-0.819 vs 0.629, 95% CI 0.522-0.735, respectively).It seemed reasonable to selectively conduct BC in patients hospitalized with severe community-onset pneumonia based upon its low overall positive rate, its effects on antimicrobial modification, and the associations of TB with the severity indices of pneumonia.

Abstract
Acute kidney injury (AKI) occurs commonly in patients with advanced cirrhosis and negatively impacts pre- and post-transplant outcomes. Physiologic changes that occur in patients with decompensated cirrhosis with ascites, place these patients at high risk of AKI. The most common causes of AKI in cirrhosis include prerenal injury, acute tubular necrosis (ATN), and the hepatorenal syndrome (HRS), accounting for more than 80% of AKI in this population. Distinguishing between these causes is particularly important for prognostication and treatment. Treatment of Type 1 HRS with vasoconstrictors and albumin improves short term survival and renal function in some patients while awaiting liver transplantation. Patients with HRS who fail to respond to medical therapy or those with severe renal failure of other etiology may require renal replacement therapy. Simultaneous liver kidney transplant (SLK) is needed in many of these patients to improve their post-transplant outcomes. However, the criteria to select patients who would benefit from SLK transplantation are based on consensus and lack strong evidence to support them. In this regard, novel serum and/or urinary biomarkers such as neutrophil gelatinase-associated lipocalin, interleukins-6 and 18, kidney injury molecule-1, fatty acid binding protein, and endothelin-1 are emerging with a potential for accurately differentiating common causes of AKI. Prospective studies are needed on the use of these biomarkers to predict accurately renal function recovery after liver transplantation alone in order to optimize personalized use of SLK.

Abstract
The isolation of Candida spp. in ascites of cirrhotic patients is an uncommon situation in clinical practice. Factors that have been associated with increased susceptibility to primary fungal peritonitis are exposure to broad-spectrum antibiotics and immunosuppression, a typical situation of these patients. We report seven episodes of Candida spp. isolation in ascites of cirrhotic patients detected in our hospital during the past 15years.

Abstract
OBJECTIVE To study the prevalence and predictive factors of spontaneous bacterial peritonitis (SBP) in patients of cirrhosis with ascites and to study the clinical characteristics and prognosis of patients with SBP. MATERIALS AND METHODS The present study was conducted on 122 cases admitted in Department of Medicine, through emergency, in Guru Gobind Singh Medical College and Hospital, Faridkot, Punjab, India. Cases of cirrhosis (irrespective of aetiology) with ascites between the ages of 18-75 years were included in this study. Ascitic fluid of every patient was aspirated under all aseptic measures, before initiation of antibiotic therapy and was sent for biochemical analysis, culture and cytological analysis. RESULTS Mean age of patients enrolled was 50.30± 10.98 years. 85% were male and 15% were female. Alcohol (73.8%) was the leading cause of cirrhosis followed by HCV (37.7%) and HBV (4.9%). Of the 122 patients studied, 27 (20.4%) patients were diagnosed as having SBP and its variants. Monomicrobial Bacterascites (BA) was present in 5 patients and Culture Negative Neutrocytic Ascites (CNNA) was present in 22 patients. Escherichia coli were the most common isolated organism followed by Klebsiella. The various factors that predispose to development of SBP include low ascitic fluid protein concentration, a high level of serum bilirubin, deranged serum creatinine, high Child-Pugh score and high MELD score. CONCLUSION Ascitic fluid analysis remains the single most important test for identifying and assessing a course of SBP. Bedside inoculation of 10-20ml of ascitic fluid into culture bottle at patient bedside will yield better results. Early diagnosis and treatment will reduce the mortality rate in these patients.

Abstract
It takes upwards of ten years for alcohol-related liver disease to progress from fatty liver through fibrosis to cirrhosis to acute on chronic liver failure. This process is silent and symptom free and can easily be missed in primary care, usually presenting with advanced cirrhosis. At this late stage, management consists of expert supportive care, with prompt identification and treatment of bleeding, sepsis and renal problems, as well as support to change behaviour and stop harmful alcohol consumption. There are opportunities to improve care by bringing liver care everywhere up to the standards of the best liver units, as detailed in the Lancet Commission report. We also need a fundamental rethink of the technologies and approaches used in primary care to detect and intervene in liver disease at a much earlier stage. However, the most effective and cost-effective measure would be a proper evidence-based alcohol strategy.

Abstract
PURPOSE To evaluate the reticuloendothelial system (RES) function by real-time imaging blood clearance as well as hepatic uptake of superparamagnetic iron oxide nanoparticle (SPIO) using dynamic magnetic resonance imaging (MRI) with two-compartment pharmacokinetic modeling. MATERIALS AND METHODS Kinetics of blood clearance and hepatic accumulation were recorded in young adult male 01b74 athymic nude mice by dynamic T2* weighted MRI after the injection of different doses of SPIO nanoparticles (0.5, 3 or 10 mg Fe/kg). Association parameter, Kin, dissociation parameter, Kout, and elimination constant, Ke, derived from dynamic data with two-compartment model, were used to describe active binding to Kupffer cells and extrahepatic clearance. The clodrosome and liposome were utilized to deplete macrophages and block the RES function to evaluate the capability of the kinetic parameters for investigation of macrophage function and density. RESULTS The two-compartment model provided a good description for all data and showed a low sum squared residual for all mice (0.27±0.03). A lower Kin, a lower Kout and a lower Ke were found after clodrosome treatment, whereas a lower Kin, a higher Kout and a lower Ke were observed after liposome treatment in comparison to saline treatment (P<0.005). CONCLUSION Dynamic SPIO-enhanced MR imaging with two-compartment modeling can provide information on RES function on both a cell number and receptor function level.

Abstract
AIM The impact of renal dysfunction has not been well evaluated among cirrhotic patients having bacterial infections other than spontaneous bacterial peritonitis (SBP). We aimed to examine the impact of renal function impairment (RFI) among cirrhotic patients with non-SBP bacterial infections. METHODS Data of 7134 cirrhotic patients with non-SBP bacterial infections extracted from the Taiwan National Health Insurance Database, derived from the Taiwan National Health Insurance Program, in 2004 were analyzed. RESULTS A total of 579 (8.1%) patients had renal dysfunction. Of these, 223 patients had acute renal failure (ARF), and 141 had end-stage renal disease (ESRD) requiring hemodialysis before admission. The overall 30-day, 1-year and 3-year mortalities were 15.8%, 39.3% and 54.5%, respectively. Compared with the non-RFI group, the adjusted hazard ratios (HR) of 30-day mortality for RFI, ARF and ESRD were 3.20 (P < 0.001), 4.81 (P < 0.001) and 1.59 (P = 0.015); the adjusted HR of 1-year mortality for RFI, ARF and ESRD were 2.68 (P < 0.001), 3.50 (P < 0.001) and 1.84 (P < 0.001), and adjusted HR of 3-year mortality for RFI, ARF and ESRD were 2.34 (P < 0.001), 2.97 (P < 0.001) and 1.76 (P < 0.001). The adjusted HR of 30-day, 1-year and 3-year mortalities for the ARF group were 2.98 (P < 0.001), 1.74 (P < 0.001) and 1.58 (P = 0.001) compared with the ESRD group, respectively. CONCLUSION This population-based cohort study shows that RFI, especially ARF, is an independent poor prognostic factor in cirrhotic patients with non-SBP bacterial infections.

Management of infections pre- and post-liver transplantation: report of an AISF consensus conference. J Hepatol 2014; 60:1075-89. [PMID: 24384327 DOI: 10.1016/j.jhep.2013.12.021] [Citation(s) in RCA: 64] [Impact Index Per Article: 6.4] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 09/28/2013] [Revised: 12/18/2013] [Accepted: 12/19/2013] [Indexed: 02/06/2023]
Abstract
The burden of infectious diseases both before and after liver transplantation is clearly attributable to the dysfunction of defensive mechanisms of the host, both as a result of cirrhosis, as well as the use of immunosuppressive agents. The present document represents the recommendations of an expert panel commended by the Italian Association for the Study of the Liver (AISF), on the prevention and management of infectious complications excluding hepatitis B, D, C, and HIV in the setting of liver transplantation. Due to a decreased response to vaccinations in cirrhosis as well as within the first six months after transplantation, the best timing for immunization is likely before transplant and early in the course of disease. Before transplantation, a vaccination panel including inactivated as well as live attenuated vaccines is recommended, while oral polio vaccine, Calmette-Guerin's bacillus, and Smallpox are contraindicated, whereas after transplantation, live attenuated vaccines are contraindicated. Before transplant, screening protocols should be divided into different levels according to the likelihood of infection, in order to reduce costs for the National Health Service. Recommended preoperative and postoperative prophylaxis varies according to the pathologic agent to which it is directed (bacterial vs. viral vs. fungal). Timing after transplantation greatly determines the most likely agent involved in post-transplant infections, and specific high-risk categories of patients have been identified that warrant closer surveillance. Clearly, specifically targeted treatment protocols are needed upon diagnosis of infections in both the pre- as well as the post-transplant scenarios, not without considering local microbiology and resistance patterns.

Abstract
BACKGROUND & AIMS Augmented susceptibility to infections increases mortality in patients with end-stage liver disease (ESLD). We sought to determine the contribution of selected genetic variants involved in inflammatory signalling downstream of the Toll-like receptor 4 (TLR4) to severe bacterial infections (SBIs) in patients with ESLD. METHODS We retrospectively assessed incidence of SBIs in 336 adult ESLD patients enlisted for orthotopic liver transplantation (OLT) and genotyped them for TLR4 c.+1196C/T, CD14 c.-159C/T, TNFA c.-238G/A, TNFA c.-863C/A, IL1B c.-31C/T and IL1RN variable number of tandem repeats allelic variants. Principal findings were validated in an independent cohort of 332 ESLD patients. RESULTS Thirty-four percent of patients from the identification cohort and 40% of patients from the validation cohort presented with SBI while enlisted for OLT. The presence of the variant allele TNFA c.-238A (rs361525) was associated with lower serum levels of TNF-α, and with significantly decreased risk of SBI in both cohorts. Multivariate analysis showed that the relative protection from SBI associated with this allele almost completely negated the increased susceptibility to SBI owed to advanced ESLD. Although not predictive of overall mortality, the presence of the TNFA c.-238A allele was associated with a complete prevention of SBI-related pre-transplant deaths. CONCLUSIONS Our results suggest that genetic variability in inflammatory signalling is associated with the development of SBI in patients with ESLD. Specifically, we identified the importance of the TNFA c.-238A allele as a strong predictor of protection from SBI, and as a genetic marker associated with significantly improved pre-transplant survival in patients with SBI.

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
Sepsis, a systemic, deleterious host response to infection that leads to organ dysfunction, is a potentially deadly condition needing prompt identification of the causative organisms and early appropriate antimicrobial therapy. Among non-culture-based diagnostic methods, SeptiFast (SF) can be employed to speed bacterial and fungal DNA detection, but it suffers from poor sensitivity and high cost. The aim of the present study, performed in 285 febrile patients, was to develop a prediction model to restrict the SF assay to clinical cases with a high probability of positive SF results. The prevalence of SF results positive for a pathogen was 17.2 %. Independent predictors of positive results were: blood sampling within 12 h after the onset of fever [odds ratio (OR) 20.03; 95 % confidence interval (CI) 6.87-58.38; P<0.0001]; ≥0.5 ng serum procalcitonin (PCT) ml(-1) (OR 18.52; 95 % CI 5.12-67.02; P<0.0001); body temperature ≥38 °C (OR 3.78; 95 % CI 1.39-10.25; P = 0.009); ≤3 g serum albumin dl(-1) (OR 3.40; 95 % CI 1.27-9.08; P = 0.014); and ≥13 000 white blood cells mm(-3) (OR 2.75; 95 % CI 1.09-7.69; P = 0.05). The model showed good calibration (Hosmer-Lemeshow chi-squared 1.61; P = 0.978). Area under the receiving operating characteristic curve was 0.944 (95 % CI 0.914-0.973; P<0.0001). These results suggest that a prediction model based on PCT and a few other routinely available laboratory and clinical variables could be of help in selecting patients with a high probability of SF-positive results.

Abstract
The term peritonitis indicates an inflammatory process involving the peritoneum that is most frequently infectious in nature. Primary or spontaneous bacterial peritonitis (SBP) typically occurs when a bacterial infection spreads to the peritoneum across the gut wall or mesenteric lymphatics or, less frequently, from hematogenous transmission in combination with impaired immune system and in absence of an identified intra-abdominal source of infection or malignancy. The clinical presentation of SBP is variable. The condition may manifest as a relatively insidious colonization, without signs and symptoms, or may suddenly occur as a septic syndrome. Laboratory diagnostics play a pivotal role for timely and appropriate management of patients with bacterial peritonitis. It is now clearly established that polymorphonuclear leukocyte (PMN) in peritoneal fluid is the mainstay for the diagnosis, whereas the role of additional biochemical tests is rather controversial. Recent evidence also suggests that automatic cell counting in peritoneal fluid may be a reliable approach for early screening of patients. According to available clinical and laboratory data, we have developed a tentative algorithm for efficient diagnosis of SBP, which is based on a reasonable integration between optimization of human/economical resources and gradually increasing use of invasive and expensive testing. The proposed strategy entails, in sequential steps, serum procalcitonin testing, automated cell count in peritoneal fluid, manual cell count in peritoneal fluid, peritoneal fluid culture and bacterial DNA testing in peritoneal fluid.

Abstract
Cirrhosis affects millions of people throughout the world. Two of the most serious complications of liver cirrhosis are ascites and spontaneous bacterial peritonitis (SBP). The development of ascites is related to the severity of portal hypertension and is an indicator of increased mortality. Although sodium restriction and diuretic therapy have proven effective, some patients may not respond appropriately or develop adverse reactions to diuretic therapy. In such cases, interventions such as transjugular intrahepatic portosystemic shunt (TIPS) placement are warranted. SBP is a complication of ascites that confers a very high mortality rate. Recognition and prompt treatment of this condition is essential to prevent serious morbidity and mortality. Initiation of prophylaxis in SBP remains controversial. Given the burden of liver cirrhosis on the health care system, ascites and SBP will continue to provide challenges for the primary care provider, hospitalist, internist, and gastroenterologist alike.

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 Acute kidney injury (AKI) is frequent in cirrhotic patients but its best definition is unclear. Recently, the Acute Kidney Injury Network (AKIN) proposed criteria to define AKI. The aims of this study were to apply AKIN criteria to cirrhotic patients with ascites and to evaluate its association to hospital mortality. STUDY In this retrospective study, cirrhotic patients with ascites admitted to a university hospital in Brazil between November 2003 and December 2007 were included. AKIN criteria were applied in the first 48 hours of hospitalization, considering 2 values of creatinine in this period. Association of AKI at admission and hospital mortality was analyzed. RESULTS Of the 198 patients in the study, 91 (46%) presented AKI at hospital admission. Overall hospital mortality was 40.4%. Patients without AKI had a hospital mortality rate of 29.9%, whereas the same rate for patients with this complication was 52.7% (odds ratio=2.6; 95% confidence interval, 1.5-4.7; P=0.001). In a logistic regression analysis, 4 variables were independently associated to hospital mortality: infection, hepatic encephalopathy, Child score, and AKI. A receiver operating characteristic curve analysis revealed that the variation in creatinine proposed by AKIN had the best combination of sensitivity and specificity in relation to hospital mortality. CONCLUSIONS In cirrhotic patients with ascites, prevalence of AKI at hospital admission is high. Patients with renal dysfunction defined by AKIN have significant higher hospital mortality. AKIN criteria are useful in cirrhotic patients with ascites, as it identifies earlier patients with worse prognosis.

Abstract
Background. The role of Aeromonas species (sp.) in bacteremia in Japanese patients with liver cirrhosis is poorly understood. Aim. To establish the importance of Aeromonas sp. as a cause of bacteremia in patients with liver cirrhosis. Methods. Clinical and serological features and short-term prognosis were retrospectively investigated and compared in Japanese patients with bacteremia due to Aeromonas sp. (n = 11) and due to enterobacteria (E. coli, Klebsiella sp., and Enterobacter sp.) (n = 84). Results. There were no significant differences in patients' clinical background, renal dysfunction, or short-term mortality rate between the two groups. However, in the Aeromonas group, the model for end-stage liver disease (MELD) score and Child-Pugh score were significantly higher than in the enterobacteria group. Conclusion. These results indicate that the severity of liver dysfunction in Aeromonas-induced bacteremia is greater than that in enterobacteria-induced bacteremia in Japanese patients with liver cirrhosis.

Abstract
PURPOSE OF REVIEW A population of patients with previously compensated cirrhosis will develop acute deterioration resulting in multiorgan failure and high short-term mortality. Complications of cirrhosis frequently culminate in admissions to the ICU. This review advances the concept of acute-on-chronic liver failure as a distinct clinical entity. RECENT FINDINGS Recently, the American Association for the Study of Liver Disease and the European Association for the Study of the Liver created a research consortium to advance the state of the science of acute-on-chronic liver failure. The goal of this consortium is aimed at improving outcomes, identification of a subset of patients with cirrhosis at high risk for deterioration, and the inciting events that lead to this deterioration. Liver transplant remains the only curative option for advanced cirrhosis; however, the limited number of available organs necessitates innovations in the care of advanced liver disease. Liver replacement therapies have not as yet demonstrated reduction in mortality, but have demonstrated improvements in other measures. Large-scale prospective studies of cirrhosis are required. SUMMARY Acute-on-chronic liver failure may be a distinct clinical entity with a potential for reversibility when identified early and managed with aggressive critical care support.

Abstract
PURPOSE To assess the prevalence of spontaneous bacterial peritonitis (SBP) in asymptomatic patients with decompensated liver cirrhosis. MATERIAL AND METHODS Patients (pts) with symptoms of decompensation of liver cirrhosis, ascites, and no signs indicating SBP were included to our study. Exclusion criteria include: 1/ clinical symptoms of infection, 2/ developing de novo or worsening hepatic encephalopathy, 3/ gastrointestinal bleeding within the last month, 4/ renal failure, 5/ antibiotic treatment or norfloxacin prophylaxis at admission. About 60 ml of ascitic fluid were drawn for lab examination. Pathologic assessment for atypical cells was also performed. RESULTS 37 patients fulfilled inclusion criteria. Their mean age was 56.2 ± 12.1. The Child-Pugh classification revealed 13 (35.1%) patients of class B and 24 (64.9%) patients of class C. The mean Model for End-Stage Liver Disease score in this group was 16.6 ± 6.8. The mean ascitic protein content was 1.85 ± 1.09 g/dL and mean neutrophil count 144.8 ± 445.1/mm3. Ascitic fluid analysis revealed: signs of bacterascites in 6 of 37 (16.2%) pts; neutrocytic ascites in 1 of 37 (2.7%) pts; and 2 of 37 (5.4%) pts met criteria for SBP. C-reactive protein level was the best predictor of infection [SBP(+) 47.9 ± 40.9 versus SBP(-) 11.7 ± 5.1; p= 0.0005]. CONCLUSIONS The prevalence of SBP in asymptomatic cirrhotics with ascites is low. We observed the trend towards more frequent occurrence of the infection in patients suffered from severe liver disease (Child-Pugh C group).

Abstract
Background/Aims Deterioration of renal function in cirrhotic patients with spontaneous bacterial peritonitis (SBP) is a predictor for in-hospital mortality; however, the clinical significance of renal dysfunction during bacterial infection other than SBP is unknown. The aim of this study was to investigate the prevalence and clinical significance of renal dysfunction due to bacterial infections other than SBP in patients with liver cirrhosis. Methods Retrospective data from inpatients with bacterial infections other than SBP were analyzed. Results Eighty patients were recruited for the analysis. The types of infections included that of urinary tract (37.5%), pneumonia (23.8%), biliary tract (20%), cellulitis (12.5%), and bacteremia of unknown origin (6.3%). Renal dysfunction developed in 29 patients (36.3%), of which 11 patients had irreversible renal dysfunction. The initial MELD score, neutrophil count, albumin, and blood pressure were significant risk factors in the univariate analysis, whereas only the MELD score was an independent risk factor for the development of renal dysfunction (p<0.001) after multivariate analysis. Conclusions The prevalence of renal dysfunction during bacterial infection other than SBP in patients with liver cirrhosis was 36.3%, and its development was related to the severity of the liver disease. Occurrence of irreversible renal dysfunction seemed to affect the prognosis of these patients.

Abstract
BACKGROUND Cirrhosis is associated with elevated levels of acute-phase proteins (APP), irrespective of the presence of infection. This condition limits the clinical application of APP determination in cirrhotic patients with bacterial infections. AIMS To weigh the diagnostic value of several APP in cirrhotics with or without bacterial infection, and to correlate them with the clinical outcome. METHODS We investigated 88 consecutive cirrhotic patients (67 males, 21 females; range 28-85 years) with mean age (SD) 58.9 (13.8) on admission, according to a standard protocol for infection. We measured the following APP: C-reactive protein (CRP), fibrinogen (FIB), haptoglobin (Hpt), ferritin (Fer), beta2-microglobulin (beta2-mg), C3, C4 and C1 inhibitor. RESULTS From the 88 patients, 19 (21.6%) had documented infection at the entry based on clinical, radiological and microbiological data. This group of patients did not differ in basic demographics from those without infection. CRP [17.5 (20.7) vs 77.1 (43.9), P<0.001], beta2-mg [4.4 (4.1) vs 5.6 (2.2), P<0.001] and ferritin [461.2 (776.4) vs 825.8 (870), P=0.03] were significantly higher in infection, whereas C3 was significantly lower. No significant differences were noted in the remaining APP levels between the two groups. After receiver operating characteristic curves were fitted, CRP was the best diagnostic test for infection (area under the curve 0.91), followed by beta2-mg, ferritin, FIB, C1 inhibitor, C4, Hpt and C3. CONCLUSIONS Serum CRP is the best test, among the examined APP, to discriminate bacterial infection in cirrhotics. A cut-off value of >55.8 mg/L has high sensitivity (79%) and specificity (96%), with the best diagnostic accuracy (92%).

Abstract
BACKGROUND/AIMS Some evidence suggests that the systemic inflammatory response syndrome (SIRS) contributes to the poor outcome of cirrhotic patients. We studied 141 cirrhotic patients consecutively admitted to a tertiary referral centre assessing prevalence of SIRS and its relationship with in-hospital outcome. METHODS Presence of SIRS was assessed on admission and during hospital stay. Main clinical outcomes were death and development of portal hypertension-related complications. RESULTS Thirty-nine patients met SIRS criteria. SIRS was present on admission in 20 of 141 patients (14.1%), whereas it occurred during hospital stay in 19 of 121 (15.7%). SIRS was correlated with bacterial infection at admission (p=0.02), jaundice (p=0.011), high serum creatinine levels (p=0.04), high serum bilirubin levels (p=0.002), high international normalized ratio (p=0.046), high model of end-stage liver disease (MELD) score (p=0.001), and high SOFA score (p=0.003). During a follow-up of 14+/-8 days, 16 patients died (11%), 7 developed portal hypertension-related bleeding (5%), 16 hepatic encephalopathy (11%), and 5 hepatorenal syndrome type-1 (3.5%). SIRS was correlated both to death (p<0.001) and to portal hypertension-related complications (p<0.001). On multivariate analysis, SIRS and MELD were independently associated with death. CONCLUSIONS SIRS frequently occurs in patients with advanced cirrhosis and is associated with a poor outcome.

Abstract
Background Low socioeconomic status is a risk factor for liver cirrhosis, but it is unknown whether it is a prognostic factor after cirrhosis diagnosis. We examined whether marital status, employment, and personal income were associated with the survival of cirrhosis patients. Methods Using registry-data we conducted a population-based cohort study of 1,765 Danish cirrhosis patients diagnosed in 1999–2001 at age 45–59 years. Follow-up ended on 31 December 2003. With Cox regression we examined the associations between marital status (never married, divorced, married), employment (employed, disability pensioner, unemployed), personal income (0–49, 50–99, 100+ percent of the national average) and survival, controlling for gender, age, cirrhosis severity, comorbidity, and substance abuse. Results Five-year survival was higher for married patients (48%) than for patients who never married (40%) or were divorced (34%), but after adjustment only divorced patients had poorer survival than married patients (adjusted hazard ratio for divorced vs. married = 1.22, 95% CI 1.04–1.42). Five-year survival was lower for disability pensioners (31%) than for employed (46%) or unemployed patients (48%), also after adjustment (adjusted hazard ratio for disability pensioners vs. employed = 1.35, 95% CI 1.09–1.66). Personal income was not associated with survival. Conclusion Marital status and employment were associated with the survival of cirrhosis patients. Specifically, divorced cirrhosis patients and cirrhosis patients who never married had a poorer survival than did married cirrhosis patients, and cirrhosis patients who were disability pensioners had a poorer survival than did employed or unemployed cirrhosis patients. The poorer survival for the divorced and for the disability pensioners could not be explained by differences in other socioeconomic factors, gender, age, cirrhosis severity, substance abuse, or comorbidity. Personal income was not associated with survival.

Abstract
STUDY DESIGN A retrospective study of a consecutive series of all patients with pyogenic spinal infections treated at a single institution over a 10-year period. OBJECTIVE To investigate risk factors for neurologic impairment with pyogenic spinal infections. SUMMARY OF BACKGROUND DATA Pyogenic spinal infections are frequently associated with neurologic deficit at the time of initial diagnosis. Current evidence suggests that advanced age, diabetes mellitus, rheumatoid arthritis, systemic corticosteroid therapy, impaired immune status, infection with Staphylococcus aureus, and more proximal infections are risk factors for neurologic involvement. To the authors' knowledge, however, the influence of chronic liver failure or concomitant nonspinal infection has not been previously investigated. METHODS A review of all patients discharged with a diagnosis of pyogenic spinal infection was performed. Data were collected, including age, sex, site of infection, degree of neurologic impairment, bacterial organism isolated, and various medical comorbidities such as diabetes mellitus, rheumatoid arthritis, chronic corticosteroid therapy, chronic liver failure, chronic renal failure, smoking, human immunodeficiency virus infection, intravenous drug abuse, cancer, cardiac disease, and the presence of a distant, nonspinal site of infection. RESULTS Fifty-five consecutive patients with pyogenic spinal infections were identified. Statistical analysis demonstrated that the presence of an epidural abscess, chronic liver failure, or a distant nonspinal infection were the only significant risk factors for neurologic involvement. CONCLUSION The current data suggest that chronic liver failure and the presence of a distant nonspinal infection are possible risk factors for neurologic involvement in patients with pyogenic spinal infections. These risk factors have not been previously described. This knowledge warrants closer surveillance for neurologic deficit in patients with these conditions.

Antiviral therapy increases the risk of bacterial infections in HCV-infected cirrhotic patients awaiting liver transplantation: A retrospective study. J Hepatol 2009; 50:719-28.

Abstract
BACKGROUND/AIMS Recurrence of hepatitis C after liver transplantation (LT) is universal and may cause premature graft loss. We evaluated the efficacy and safety of antiviral therapy in HCV-infected patients with decompensated cirrhosis awaiting LT. METHODS Fifty-one patients underwent treatment with peginterferon-alfa-2a and ribavirin. A control group of 51 untreated individuals awaiting LT were matched by age, Child-Pugh and MELD scores and time on the waiting list. RESULTS Case and control patients were comparable for all relevant variables. Fifteen treated patients (29%) had undetectable HCV-RNA at the time of transplantation and 10 (20%) achieved SVR. Early virological response and non-1 genotype were the strongest predictors of viral clearance. There was a higher incidence of bacterial infections in treated patients vs controls, particularly in Child-Pugh B-C individuals (17 vs 3 episodes) (log-rank=0.0016). Importantly, the incidence of spontaneous bacterial peritonitis (SBP) in patients who were not receiving norfloxacin prophylaxis (n=83) was significantly higher in the treated group than in controls (log-rank=0.01). CONCLUSIONS Our data demonstrate that antiviral treatment prevents hepatitis C recurrence in 20% of HCV-infected patients. However, treatment should be recommended with caution in individuals with poor liver function who do not receive norfloxacin prophylaxis for SBP, since it increases the risk of bacterial infections.

Abstract
PURPOSE The study aimed to describe the clinical outcome of patients with liver cirrhosis admitted to intensive care unit (ICU) and to compare the performance of Acute Physiology and Chronic Health Evaluation (APACHE) II and Sequential Organ Failure Assessment (SOFA) in predicting mortality. METHODS In this prospective study of patients with cirrhosis admitted to the ICU, demographic data, APACHE II score, SOFA score, presence of acute renal failure (ARF), need for organ support, and mortality were collected. RESULTS The observed mortality in ICU and at 30 days among 104 patients was 42.3% (95% confidence interval [CI], 32.7%-52.0%) and 56.7% (95% CI, 47.0%-66.4%), respectively. Area under the receiver operating characteristic curve for first-day APACHE II in predicting 30-day mortality was 0.90 (95% CI, 0.83-0.96) and 0.93 (95% CI, 0.88-0.98) for SOFA score (P = .24). On multivariate analysis, ARF (adjusted odds ratio, 7.7; 95% CI, 1.09-54.64) and mechanical ventilation (adjusted odds ratio, 277.6; 95% CI, 12.83-6004.94) were significantly associated with mortality. CONCLUSIONS Presence of ARF and need for mechanical ventilation are associated with high mortality in patients with liver cirrhosis admitted to the ICU. Acute Physiology and Chronic Health Evaluation II and SOFA are good prognostic models in predicting 30-day mortality and do not differ in performance.

Abstract
BACKGROUND The prevalence of end-stage liver disease is rising rapidly and constitutes a major healthcare burden currently. Many cases are diagnosed at a later stage when liver transplantation is the only effective treatment option. There is thus an urgent need for novel treatments to reverse the earlier stages of cirrhosis as well as to treat the many associated life-threatening complications. OBJECTIVES To review the current drugs available for treating the complications of advanced liver disease. To address novel treatment strategies that are in development, with particular reference to the rapidly developing area of antifibrotic therapy. To assess how the obstacles that have so far impeded the development of effective new drugs for end-stage liver disease may be overcome in the future. METHODS The literature was reviewed to define current therapies and therapies in clinical trials. We used the current models of the molecular basis of liver fibrogenesis to determine potential new therapeutic targets for antifibrotic therapy. CONCLUSIONS Insights into the pathogenesis of liver injury and fibrosis have opened up new avenues for therapy and there are now candidates and targets with real potential for the development of a new generation of antifibrotic therapies.

Abstract
Renal dysfunction is common in liver diseases, either as part of multiorgan involvement in acute illness or secondary to advanced liver disease. The presence of renal impairment in both groups is a poor prognostic indicator. Renal failure is often multifactorial and can present as pre-renal or intrinsic renal dysfunction. Obstructive or post renal dysfunction only rarely complicates liver disease. Hepatorenal syndrome (HRS) is a unique form of renal failure associated with advanced liver disease or cirrhosis, and is characterized by functional renal impairment without significant changes in renal histology. Irrespective of the type of renal failure, renal hypoperfusion is the central pathogenetic mechanism, due either to reduced perfusion pressure or increased renal vascular resistance. Volume expansion, avoidance of precipitating factors and treatment of underlying liver disease constitute the mainstay of therapy to prevent and reverse renal impairment. Splanchnic vasoconstrictor agents, such as terlipressin, along with volume expansion, and early placement of transjugular intrahepatic portosystemic shunt (TIPS) may be effective in improving renal function in HRS. Continuous renal replacement therapy (CRRT) and molecular absorbent recirculating system (MARS) in selected patients may be life saving while awaiting liver transplantation.

Abstract
Viral infections, specifically chronic, markedly influence the host response to subsequent infections and vaccinations. Does this apply to chronic hepatitis C (CHC)? The review considers this question with implications for the immune status and functionality of the immune system of a chronically HCV-infected host. The data collected here indicate that CHC may increase the risk of viral superinfections and modify their course by immunocompromising the host. Patients with CHC do not lose the 'memory' of previous infections and vaccinations but, apparently, have problems with building such immunity anew, as illustrated by their impaired response to hepatitis A and B vaccinations. This underlines the necessity of extra protection of CHC patients against blood-borne diseases, hepatitis A, possibly also varicella, influenza, tetanus, and diphtheria - immunity to which, in the Western population, appears to falter. Such immune protection has to be adapted to selective impairments of immune response characteristic to CHC. Some approaches to this are reviewed here and more need to be elaborated. Special attention has to be given to CHC patients who do not respond to common vaccines; further studies in this field are of great interest.

Abstract
Bacteremia has rarely been reported in patients receiving treatment for hepatitis C virus (HCV) infection. We describe the features and investigation of four cases of Staphylococcus aureus bacteremia occurring between 3 November 2004 and 10 January 2005 in patients on therapy for chronic HCV infection. The unusual occurrence of S. aureus bacteremia in a series of patients led to an epidemiologic investigation and molecular typing methods were employed to assess the relatedness of cases. The mean time of bacteremia onset was week 10 of HCV treatment. No patient had neutropenia previously. The average duration of bacteremia was 2.6 days and complications included acute renal failure (2/4), disseminated intravascular coagulopathy (DIC) with sepsis syndrome (1/4), septic arthritis (1/4), spinal epidural abscess (1/4) and endocarditis (1/4). Two patients were in the same weight class for dosing, but no other epidemiologic links were found. One patient admitted to intravenous drug use (IVDU) and a second was suspected of IVDU. The two other patients were cirrhotic, but had no further identifiable risk factors. All bacterial isolates were methicillin-susceptible. By pulsed-field gel electrophoresis, two cases were found to have identical bacterial strains. However, fluorescent-based amplified fragment-length polymorphism analysis demonstrated distinct band patterns in all four cases. The epidemiologic data and molecular analysis of this cluster of S. aureus bacteremia cases among patients receiving combination therapy for treatment of chronic HCV infection suggest that these cases were not related. Additionally, IVDU and cirrhosis, but not neutropenia, are identified as potential risk factors for this uncommon complication of HCV therapy.

Abstract
Bacterial infections are well described complications of cirrhosis that greatly increase mortality rates. Two factors play important roles in the development of bacterial infections in these patients: the severity of liver disease and gastrointestinal haemorrhage. The most common infections are spontaneous bacterial peritonitis, urinary tract infections, pneumonia and sepsis. Gram-negative and gram-positive bacteria are equal causative organisms. For primary prophylaxis, short-term antibiotic treatment (oral norfloxacin or ciprofloxacin) is indicated in cirrhotic patients (with or without ascites) admitted with gastrointestinal haemorrhage (variceal or non-variceal). Administration of norfloxacin is advisable for hospitalized patients with low ascitic protein even without gastrointestinal haemorrhage. The first choice in empirical treatment of spontaneous bacterial peritonitis is the iv. III. generation cephalosporin; which can be switched for a targeted antibiotic regime based on the result of the culture. The duration of therapy is 5-8 days. Amoxicillin/clavulanic acid and fluoroquinolones--patients not on prior quinolone prophylaxis--were shown to be as effective and safe as cefotaxime. In patients with evidence of improvement, iv. antibiotics can be switched safely to oral antibiotics after 2 days. In case of renal dysfunction, iv albumin should also be administered. Long-term antibiotic prophylaxis is recommended in patients who have recovered from an episode of spontaneous bacterial peritonitis (secondary prevention). For "selective intestinal decontamination", poorly absorbed oral norfloxacin is the preferred schedule. Oral ciprofloxacin or levofloxacin (added gram positive spectrum) all the more are reasonable alternatives. Trimethoprim/sulfamethoxazole is only for patients who are intolerant to quinolones. Prophylaxis is indefinite until disappearance of ascites, transplant or death. Long-term prophylaxis is currently not recommended for patients without previous spontaneous bacterial peritonitis episode, not even when refractory ascites or low ascites protein content is present.

Abstract
BACKGROUND Bacterial infections are frequent in cirrhosis. Experimental studies suggest a pathogenic role of intestinal bacterial translocation in them. Both fermentable and non-fermentable fibre avoided intestinal bacterial translocation (IBT) in animal models of gut starvation and critical illness. AIM To assess the effect of fermentable (pectin) or non-fermentable (lignin) fibre on IBT in ascitic cirrhotic rats. METHODS Thirty-six rats induced to cirrhosis with oral CCl4 were randomized (6 weeks after the first CCl4 dose) to receive rat chow+5% lignin (LIG, n=13), rat chow+5% pectin (PEC, n=13), or rat chow only (CON, n=10). Once ascites developed, animals were laparotomized and samples of mesenteric lymph nodes (MLN), ascitic fluid, portal and peripheral blood and liver, were obtained for culture. RESULTS IBT rate was: LIG=5/13, PEC=4/13, CON=5/10 (P=N.S.). The median amount of translocated bacteria in rats with IBT was lower in the PEC group (2 x 10(2) CFU/g MLN), than in LIG (10(5) CFU/g MLN) and CON (10(4) CFU/g MLN) groups (P<0.05). All other samples were sterile except for a portal blood sample (Enterococcus faecalis) of the LIG group. CONCLUSIONS IBT incidence is not decreased by either pectin or lignin in ascitic cirrhotic rats, but pectin supplementation reduces the amount of translocated bacteria.

Abstract
An increased frequency of infections has been reported in patients with chronic liver disease. The tendency of patients in this population to acquire UTI is not completely understood. We aimed at investigating the incidence of UTI in children with cirrhosis, before liver transplantation. Twenty-six children (9 girls, 17 boys; mean age, 7.66 +/- 5.73 yr) with chronic liver disease who had undergone liver transplantation between 2002 and 2004 were included. On admission for liver transplantation, patients were examined for presence of UTI. Serum biochemistry, complete blood cell count, urinalysis and culture, glomerular filtration rate, and abdominal ultrasonography were performed prior to liver transplantation. Ten of 26 patients (38.5%) were found to have symptomatic UTI. Urine cultures revealed E. coli in five (50%), Klebsiella pneumoniae in three (30%), Enterococcus faecalis in one (10%), and Enterobacter aeruginosa in one (10%) patient(s), respectively, as etiologic factors. The etiologies of chronic liver disease in our patients with UTI were BA in five, PFIC in three, Wilson's disease in one, and alpha-1 antitrypsin deficiency in one patient. We found a significantly greater number of UTIs in patients with biliary atresia than in those without biliary atresia (p < 0.05). The mean age of the patients with UTI was 2.75 +/- 3.49 yr, which was significantly lower than in those without UTI (9.75 +/- 4.86 yr, p < 0.05). Levels for white blood cells, thrombocytes, ALT, and alkaline phosphatase were significantly higher in patients with UTI than in those without UTI. There were no significant differences between the groups with regard to serum albumin, bilirubin, AST, GGT, BUN, or creatinine levels, glomerular filtration rate, duration of disease, and PELD scores. In patients with bacteriuria, renal USG revealed normal findings in all, but except one patient who had pelvicalyceal dilatation. Scintigraphic findings demonstrated acute pyelonephritis in six (60%) patients with UTI. VCUG demonstrated vesicoureteral reflux in two patients. In conclusion, symptomatic UTI is common in children with cirrhosis. It occurs more frequently in patients with biliary atresia than it does in patients with other types of chronic liver disease. In febrile children with chronic liver disease, UTI should be considered in the differential diagnosis.

Abstract
Time-to-positivity is useful in the diagnosis of catheter-related bacteraemia and as a predictor of an endovascular source in patients with Staphylococcus aureus bacteraemia. However, this parameter has been evaluated for only a limited number of microorganisms. In the present study, time-to-positivity was recorded for 1872 episodes of significant monomicrobial bacteraemia diagnosed at a teaching hospital during a 2-year period, and the associated microbial and clinical variables were investigated. According to multivariate analysis, Streptococcus pneumoniae, beta-haemolytic streptococci, Escherichia coli, Klebsiella, Enterobacter, Citrobacter and Aeromonas were characterised by fast growth, with an endovascular source, shock, liver cirrhosis and neutropenia also predicting a short time-to-positivity. For patients not receiving appropriate antibiotics, detection of Gram-positive cocci in clusters within 14 h was predictive of Staph. aureus; a time-to-positivity of >21 h ruled out the possibility that a Gram-positive organism in chains was a beta-haemolytic streptococcus or Strep. pneumoniae, and a time-to-positivity of < or =12 h meant that it was very unlikely that a Gram-negative bacillus was a non-fermenter. A time-to-positivity of < or =8 h was predictive of a non-urinary tract source in patients with E. coli bacteraemia, and detection of growth within 13 h predicted an endovascular source in those with Staph. aureus bacteraemia. In conclusion, time-to-positivity depended on the microorganism, original source and clinical variables involved. Although this measurement may provide some early clues concerning the microorganisms involved and the source of bacteraemia, its clinical impact remains to be defined.

Abstract
The key pathogenic mechanism initiating spontaneous bacterial peritonitis (SBP) is bacterial translocation (BT), a process through which enteric bacteria cross the intestinal barrier and infect the mesenteric lymph nodes, thus entering the blood circulation and ascitic fluid. The high rate of bacterial translocation in cirrhosis is due to injury to the three pilars composing the intestinal mucosal barrier (the balance of intraluminal bacterial flora, the integrity of the intestinal epithelial barrier, and the local immune system). Blood dissemination and microbial growth in ascitic fluid resulting from SBP are a consequence of damage to the immune system in cirrhosis. Hyperproduction of proinflammatory cytokines and other vasoactive substances contributes to the arterial vasodilation and renal failure that frequently complicate the course of SBP. Even in the absence of SBP, translocation of bacteria and bacterial products from the intestinal lumen contribute to systemic inactivation of immune cells in cirrhosis.
