Spontaneous bacterial peritonitis recurrence on norfloxacin secondary prophylaxis.

BACKGROUND AND STUDY AIMS: Secondary prophylaxis with norfloxacin reduces recurrence of spontaneous bacterial peritonitis (SBP) significantly. No data available from Asia-Pacific region about recurrence of SBP in these patients. PATIENTS AND METHODS: In a retrospective cohort study, we assessed recurrence rate of SBP in patients on norfloxacin secondary prophylaxis. One year recurrence of SBP, its profile, response rate and risk factors for recurrence were assessed. RESULTS: A total of 112 patients were analysed. During first episode of SBP, culture positive rate was 39/112(34.8 %) and resistance to ceftriaxone was 51.2 %. Overall efficacy of ceftriaxone as first line antibiotic was 70.5 % (70/112), but only 49 % (19/39) among culture positive patients. E. coli is the commonest organism isolated (21/39, 53.8 %), MDR organism in 12.8 % (5/39). Cumulative incidence of SPB recurrence was 22.3 % (25/112) on norfloxacin secondary prophylaxis at 1 year. Culture positive rate in recurrent SBP was 48 % (12/25) and ceftriaxone resistance and MDR organism were seen in 66.6 % and 16.6 %. Overall response rate to ceftriaxone in recurrent SBP was 40 % (10/25) and 21 % (3/14) in culture positive patients. Risk factors for SBP recurrence were age, INR and albumin (p < 0.05). No increase cumulative incidence of death among patients with or without recurrence. CONCLUSION: Despite recent changes in bacteriological profile in SBP, recurrence of SBP on norfloxacin prophylaxis remains low. In recurrent SBP, response to ceftriaxone is significantly lower than first episode and there is trend towards increase in MDR organism in culture positive patient receiving norfloxacin.

Clostridium Perfringens as a Rare Cause of Spontaneous Bacterial Peritonitis.

Spontaneous bacterial peritonitis (SBP) is a serious complication in individuals with liver cirrhosis and ascites. In this case report, we present an unusual cause of SBP in loculated ascites caused by an uncommon bacterium, Clostridium perfringens. Although SBP is typically associated with certain common pathogens, it is important to recognize that less frequent organisms can also trigger it. C. perfringens is typically associated with other environmental sources, but in this instance, the infection's origin was suspected to be either nosocomial, from prior paracentesis, or due to a microscopic bowel perforation that was undetectable on imaging. Remarkably, the patient responded well with an improvement of symptoms, and the ascitic fluid bacterial growth resolved on subsequent cultures.

Spontaneous Bacterial Peritonitis: A Rare Incidence by Achromobacter xylosidans.

Liver cirrhosis results from progressive hepatic fibrosis and is generally considered irreversible. One of the many consequences of cirrhosis is spontaneous bacterial peritonitis. This typically presents in patients with decompensated cirrhosis due to bacterial translocation, most commonly from the intestinal bacterial flora seeding into the ascitic fluid. We present a rare case of spontaneous bacterial peritonitis caused by Achromobacter xylosidans. This bacterium is mostly associated with nosocomial infections, and due to its multidrug-resistant nature, treatment options are often limited. This case highlights a rare cause of spontaneous bacterial peritonitis to consider in the setting of recent hospitalization, and the importance of recognizing spontaneous bacterial peritonitis versus secondary bacterial peritonitis.

Portal hypertension and emergency care.

OBJECTIVE: Aim: To evaluate the peculiarities of the course of complications and the provision of care for portal hypertension associated with the development of diureticresistant ascites, spontaneous bacterial peritonitis, hepatorenal syndrome, and variceal bleeding. PATIENTS AND METHODS: Materials and Methods: This research is based on a review of the literature in PubMed, CrossRef, Google Scholar sources on complicated portal hypertension. Such complications of portal hypertension as spontaneous bacterial peritonitis, ascites, hepatorenal sуndrome, variceal bleeding caused by sinistral portal hypertension are considered. The effectiveness of interventional treatment methods and laparoscopic surgical interventions has been demonstrated. CONCLUSION: Conclusions: Diagnosis and treatment of patients with complicated portal hypertension requires a multidisciplinary approach, which is due to the diverse pathophysiological process of portal hypertension. The possibilities of providing emergency care to this category of patients depend on the level of medical training of the staff, the possibilities of medical and technical support in the provision of interventional care, the ineffectiveness of which necessitates surgical treatment using minimally invasive technologies.

[Infections and liver cirrhosis]. / Infektionen und Leberzirrhose.

End-stage liver disease is a life-threatening clinical syndrome combined with a state of immune dysfunction. In this constellation patients are prone to bacterial, fungal and viral infections associated with markedly increased morbidity and mortality rates. Bacterial infections are the most prevalent kind of infection in patients with end-stage liver disease accounting for nearly 30%. The evolving rates of multidrug resistant organisms present enormous challenges in treatment strategies. Therefore, the urgent needs for prevention, early detection strategies and widespread treatment options are a necessity to handle the rising incidence of infection complications in end-stage liver disease.

Proton Pump Inhibitors in Patients with Cirrhosis: Pharmacokinetics, Benefits and Drawbacks.

PURPOSE OF REVIEW: This review explores the pharmacokinetics, benefits, and risks of proton pump inhibitors (PPIs) in cirrhotic patients, focusing on the appropriateness of their use and potential adverse effects. RECENT FINDINGS: Recent studies highlight significant pharmacokinetic alterations in PPIs among cirrhotic patients, with marked increases in lansoprazole and pantoprazole exposure and relatively stable levels of esomeprazole. While effective for managing acid-related disorders and post-band ulcer rebleeding, evidence supporting PPI use for portal hypertension-related bleeding is lacking. Emerging research suggests potential adverse effects such as hepatic decompensation, spontaneous bacterial peritonitis, hepatic encephalopathy, and increased mortality, possibly linked to dysbiosis and bacterial translocation. PPI use in cirrhotic patients alters pharmacokinetics significantly, with esomeprazole potentially safer in advanced cirrhosis. The review advises caution in routine PPI use beyond acid-related conditions due to limited evidence and substantial risks. It underscores the need for careful risk-benefit assessments and exploration of alternative therapies. Future research should aim to identify safer management strategies for portal hypertension complications and to develop evidence-based guidelines for PPI use in patients with cirrhosis.

Clinical Insights into Brucella Peritonitis: A Comprehensive Analysis of Four Cases.

INTRODUCTION: Brucellosis, a globally distributed zoonotic disease, exhibits diverse clinical manifestations, with Brucella peritonitis being a rare but consequential complication. METHODS: Analyzing the medical records of four patients with Brucella peritonitis admitted to the First People's Hospital of Kashi Region from January 2022 to November 2023. A retrospective approach was used to analyze the general data, epidemiological history, clinical features, laboratory tests, and efficacy. All four patients with Brucella peritonitis were farmers. RESULTS: All of them were combined with decompensated stage of liver cirrhosis. The main manifestations were poor appetite, fatigue, bloating. Two patients were accompanied by moderate-high fever. All patients presented with mildly elevated C-reactive protein and procalcitonin < 0.25ng/ml. Brucella was cultured from blood in 2 cases, from pleural fluid in 1 case, and from ascitic fluid in another case. All patients had moderate-to-large amounts of ascites with elevated leukocytes in the ascites, predominantly mononuclear cells. Symptoms of the above patients were reduced or disappeared after effective anti-infection. CONCLUSION: When patients with decompensated cirrhosis present with exudative ascites dominated by elevated mononuclear cells, the possibility of Brucella peritonitis should also be considered in areas where brucellosis is endemic.

Role of Systemic Immune Inflammation Index, Systemic Immune Response Index, Neutrophil Lymphocyte Ratio and Platelet Lymphocyte Ratio in Predicting Peritoneal Culture Positivity and Prognosis in Cases of Spontaneous Bacterial Peritonitis Admitted to the Emergency Department.

Background and Objectives: Spontaneous bacterial peritonitis (SBP) is a life-threatening disease that requires early diagnosis and treatment. It is known that a positive culture result for SBP, which is a common reason for admission to the emergency department, is related to the severity and prognosis of the disease. However, as it is not possible to determine the culture result in the early stage of the disease, different methods are required to predict prognosis in the emergency department. This study was conducted to evaluate the success of the SII, SIRI, NLR and PLR in predicting culture results, intensive care needs and mortality in patients with SBP admitted to the emergency department. Materials and Methods: This study was a retrospective, observational study. Patients with SBP who applied to the emergency department were included in this study. Pregnant women, patients with a malignancy, patients with another infection and patients with liver failure were excluded from this study. Data were analyzed in terms of culture results, the need for intensive care and mortality development. Analyses were performed using SPSS version 26. Results are presented with a 95% confidence interval. A p value less than 0.05 was considered statistically significant. Participant data were analyzed using the independent samples t-test or the Mann-Whitney U test based on normality, and ROC analyses were conducted to assess test accuracies and determine cut-off values. Results: A total of 275 patients were included in this study. Although the culture results of 183 patients were positive, 92 were negative. The SII, NLR and PLR were found to be significantly higher in culture-positive patients (p < 0.001, p = 0.013 and p = 0.002, respectively). The SII and NLR were found to be significantly higher in patients with high mortality (p < 0.001 and p = 0.017, respectively). Conclusions: This study showed that the SII, NLR and PLR may be useful in predicting culture positivity and prognosis in SBP patients in the emergency department.

Towards evidence-based empiric antibiotic recommendations for spontaneous infections in patients with cirrhosis.

BACKGROUND: With the emergence of multidrug-resistant infections, healthcare professionals must evaluate the effectiveness of empiric antibiotic treatments. AIMS: To assess the antibiotic susceptibility patterns of microorganisms causing spontaneous infections in patients with cirrhosis and to evaluate the suitability of empiric antibiotic treatments based on major clinical guidelines. METHODS: This cross-sectional study utilized two datasets from prospective studies of patients with cirrhosis and culture-positive spontaneous bacterial infections in Argentina and Uruguay. We estimated susceptibility to commonly used antibiotics and assessed coverage following European and American recommendations. RESULTS: We analyzed 238 episodes of culture-positive spontaneous infections in 229 patients. When implementing the recommendations for empiric treatment of community-acquired spontaneous infections, ceftazidime would result in 39 % coverage, whereas ceftriaxone would reach 70 %. Cefepime, which is not included in the recommendations, would have provided coverage of 74 %. Using ertapenem for nosocomial infections would have only covered 56 % of these episodes, whereas meropenem or imipenem reached 73 % coverage. Only the combination of meropenem or imipenem plus vancomycin would achieve a coverage surpassing 85 % in healthcare-associated or nosocomial spontaneous bacterial infections. CONCLUSIONS: Our study uncovers inadequate coverage in specific clinical scenarios when adhering to recommendations, underscoring the necessity of guidelines based on local epidemiological data.

Chinese guidelines on the management of ascites in cirrhosis : Chinese Society of Hepatology, Chinese Medical Association.

In 2023, Chinese Society of Hepatology of Chinese Medical Association convened a panel of experts to update the Chinese guidelines on the management of ascites and associated complications in cirrhosis which was launched in 2017 and renamed this guidelines as "Guidelines on the Management of Ascites in Cirrhosis." This comprehensive resource offers essential recommendations for the diagnosis and treatment of cirrhotic ascites, spontaneous bacterial peritonitis, and hepatorenal syndrome.

Use of Bacterial DNA Concentration in Ascites as a Marker for Spontaneous Bacterial Peritonitis.

Background and aims: Spontaneous bacterial peritonitis (SBP) is a common and serious complication in patients with decompensated cirrhosis. Precise quantification of bacterial DNA (bactDNA) and the related inflammatory response might add further information on the course of disease. The aim of the study was to evaluate the association between bactDNA, cytokine levels and clinical outcome. Methods: Ascites and serum samples of 98 patients with decompensated liver cirrhosis (42 with SBP and 56 without SBP) as well as serum samples of 21 healthy controls were collected. BactDNA in ascites and serum was detected and quantified by 16S rRNA PCR. Concentrations of IL-1ß, TNF-α, IL-6, IL-8 and IL-10 were measured by a LEGENDplexTM multi-analyte flow assay. Clinical data were collected and analyzed retrospectively. Results: BactDNA was detected more frequently in ascites of patients with SBP (n = 24/42; 57.1%) than in ascites of patients without SBP (n = 5/56; 8.9%; P < 0.001). Additionally, IL-6 levels in both ascites and serum were significantly higher in patients with SBP (ascites P < 0.001, serum P = 0.036). The quantity of bactDNA in ascites was strongly correlated with polymorphonuclear neutrophil count in ascites (r = 0.755; P < 0.001) as well as ascites IL-6 levels (r = 0.399; P < 0.001). Receiver operating characteristic (ROC) curve analysis to diagnose SBP provided an AUC of 0.764 (95% CI: 0.661-0.867) for serum IL-6 levels, an AUC of 0.810 (95% CI: 0.714-0.905) for ascites IL-6 levels, and an AUC of 0.755 (95% CI: 0.651-0.858) for bactDNA levels in ascites. Conclusions: The correlation between the amount of bactDNA and IL-6 confirms the pathophysiological relevance of bactDNA and IL-6 as potential biomarkers for the diagnosis of SBP.

LINAS-Score: prognostic model for mortality assessment in patients with cirrhotic liver and infected ascites.

BACKGROUND AND AIM: Patients with liver cirrhosis often face a grave threat from infected ascites (IA). However, a well-established prognostic model for this complication has not been established in routine clinical practice. Therefore, we aimed to assess mortality risk in patients with liver cirrhosis and IA. METHODS: We conducted a retrospective study across three tertiary hospitals, enrolling 534 adult patients with cirrhotic liver and IA, comprising 465 with spontaneous bacterial peritonitis (SBP), 34 with bacterascites (BA), and 35 with secondary peritonitis (SP). To determine the attributable mortality risk linked to IA, these patients were matched with 122 patients with hydropic decompensated liver cirrhosis but without IA. Clinical, laboratory, and microbiological parameters were assessed for their relation to mortality using univariable analyses and a multivariable random forest model (RFM). Least absolute shrinkage and selection operator (Lasso) regression model was used to establish an easy-to-use mortality prediction score. RESULTS: The in-hospital mortality risk was highest for SP (39.0%), followed by SBP (26.0%) and BA (25.0%). Besides illness severity markers, microbiological parameters, such as Candida spp., were identified as the most significant indicators for mortality. The Lasso model determined 15 parameters with corresponding scores, yielding good discriminatory power (area under the receiver operating characteristics curve = 0.89). Counting from 0 to 83, scores of 20, 40, 60, and 80 corresponded to in-hospital mortalities of 3.3%, 30.8%, 85.2%, and 98.7%, respectively. CONCLUSION: We developed a promising mortality prediction score for IA, highlighting the importance of microbiological parameters in conjunction with illness severity for assessing patient outcomes.

Spontaneous Bacterial Peritonitis Because of Actinomyces.

Actinomycosis is a rare chronic granulomatous disease that manifests with nonspecific symptoms of abdominal pain, anorexia, and weight loss. The disparity in the presentation of this condition presents a tremendous diagnostic challenge. There are few reports of Actinomyces species causing spontaneous bacterial peritonitis without previous localized masses or abscesses have been published. We provide a case of spontaneous bacterial peritonitis secondary to Actinomyces species in a 46-year-old woman with uterine fibroids and a lack of preceding abscess. Although rare, spontaneous bacterial peritonitis because of Actinomyces should be considered in differential in female patients without pre-existing liver disease presenting with spontaneous bacterial peritonitis.

Noninfectious Ascites Neutrophilia in a Patient With Polycythemia Vera.

A 59-year-old woman with polycythemia vera-related portal hypertension requiring frequent paracentesis was admitted for asymptomatic recurrent spontaneous bacterial peritonitis, which was diagnosed based on elevated polymorphonuclear (PMN) count. She had multiple similar admissions during which she was treated with antibiotics. The patient had chronic baseline leukocytosis due to polycythemia vera. Repeat paracentesis after intravenous antibiotics demonstrated persistent elevation of PMN count without clinical symptoms. A multidisciplinary team concluded that the increased PMN count was secondary to polycythemia. The patient was diagnosed with omental extramedullary hematopoiesis, a rare condition causing elevated PMN count in the absence of bacterial contamination.

Epidemiological Study of Pathogens in Spontaneous Bacterial Peritonitis in 2017-2024-A Preliminary Report of the University Hospital in South-Eastern Poland.

Spontaneous Bacterial Peritonitis (SBP) is a serious complication and a common cause of death in patients with liver cirrhosis. Between January 2017 and March 2024, a retrospective study was conducted involving 302 patients (>18 years old) with ascites treated at a tertiary referral center in south-eastern Poland. Microbiological analysis of the ascitic fluids was performed in all patients. The presence of microorganisms was found in samples from 17 patients, and 21 pathogens were isolated, including 15 Gram-positive bacteria and 6 Gram-negative bacteria. Staphylococcus epidermidis, MRCNS (methicillin-resistant coagulase-negative staphylococci, resistant to all beta-lactam antibiotics: penicillins, penicillins with beta-lactamase inhibitor, cephalosporins and carbapenems) was the main pathogen detected (19.05%, 4/21), followed by Enterococcus faecalis (9.52%, 2/21), Enterococcus faecium (9.52%, 2/21), Staphylococcus haemolyticus, MRCNS (4.76%, 1/21), Streptococcus mitis (9.52%, 2/21), Streptococcus parasanguinis (9.52%, 2/21), Micrococcus luteus (4.76%, 1/21) and Bacillus spp. (4.76%, 1/21). The following Gram-negative bacteria were also found in the specimens examined: Escherichia coli, ESBL (extended-spectrum ß-lactamase producing E. coli) (4.76%, 1/21), Escherichia coli (4.76%, 1/21), Pseudomonas aeruginosa (4.76%, 1/21), Klebsiella oxytoca (9.52%, 2/21) and Sphingomonas paucimobilis (4.76%, 1/21). Gram-positive bacteria caused nosocomial infections in nine patients with SBP, Gram-negative bacteria caused nosocomial infections in two patients. In six patients with SBP, community-acquired infections caused by Gram-negative bacteria were found in three cases, Gram-positive bacteria in two cases, and in one case, community-acquired infection was caused by mixed Gram-positive and Gram-negative. Bacteria isolated from patients with hospital-acquired SBP showed higher drug resistance than those found in patients with non-hospital SBP. Bacterial infections in cirrhotic patients with complications may be responsible for their deteriorating health. Prompt intervention is critical to reducing mortality.

A Patient of Spontaneous Bacterial Peritonitis in Hepatitis C Cirrhosis Caused by Gordonia terrae: A Case Report.

Background: Gordonia terrae is an opportunistic pathogen that rarely causes clinical infections. Here, we first report a case of spontaneous bacterial peritonitis in patients with hepatitis C cirrhosis caused by Gordonia terrea. Case Presentation: A 71-year-old male patient was diagnosed with spontaneous bacteria peritonitis secondary to hepatitis C cirrhosis. The result of bacterial culture in ascites was positive, and the pathogenic bacteria was preliminarily identified as the Gordonia genus by matrix-assisted laser desorption ionization-time of flight mass spectrometry. After 16S rRNA sequencing analysis, it was determined to be the Gordonia terrea. Symptoms relieved after treatment with ceftazidime. Conclusion: This case indicates that the clinical infections caused by Gordonia terrea should be brought to the forefront. Accurate and rapid bacterial identification results are highly beneficial to the diagnosis and therapeutic regime.

Navigating the controversy regarding antibiotic prophylaxis in acute variceal bleeding.

Antibiotic prophylaxis in patients with cirrhosis and acute variceal bleeding is part of the standard of care according to most clinical guidelines. However, with recent evidence arguing against antibiotic prophylaxis, the role of this intervention has become less clear.

Neutrophil percentage-to-albumin ratio is a new diagnostic marker for spontaneous bacterial peritonitis: a prospective multicenter study.

BACKGROUND: The neutrophil percentage-to-albumin ratio (NPAR) is a novel measure of systemic inflammation and infection. Low albumin levels increase the risk of infection, while high neutrophil counts indicate the presence of infection. Spontaneous bacterial peritonitis (SBP) is a serious infection in cirrhotic ascites, and the potential of NPAR in diagnosing SBP is not yet established. OBJECTIVE: The objective of this study is to determine the diagnostic value of NPAR in identifying SBP. PATIENTS: This prospective multicenter study included 465 patients diagnosed with cirrhotic ascites and SBP according to international guidelines. Demographic, clinical, and laboratory data were collected. The sensitivity and specificity of NPAR values for diagnosing SBP were assessed using the receiver operating characteristic curve. RESULTS: For SBP diagnosis in the total cohort, NPAR of > 17 had a sensitivity of 85.71%, specificity of 66.67%, and 95% CI (42.1-99.6). In culture-positive SBP, the NPAR at a cut-off > 5.2 had a sensitivity of 85.71%, specificity of 83.33%, and 95% CI (0.709 to 0.979), while in culture-negative SBP, the NPAR at a cut-off > 2.1 had a sensitivity of 92.86%, specificity of 33.33% and CI (0.367 to 0.764). The multivariate analysis revealed that albumin (OR = 2.78, [1.11;3.98], INR (OR = 0.198, [0.066;0.596], creatinine (OR = 0.292, [0.1; 0.81], CRP (OR = 3.18, [1.239;4.52] total leukocytic count (TLC) (OR = 1.97, [1.878; 2.07], platelets (OR = 2.09, [0.99; 2.31] and neutrophil (OR = 3.43, [1.04;3.89] were significantly associated with higher prediction rates for culture positive SBP. CONCLUSIONS: NPAR could be a new, affordable, noninvasive test for diagnosing SBP.

Comparative Analysis of Demographic and Clinical Findings in Spontaneous, Peritoneal Dialysis-Related, and Secondary Bacterial Peritonitis.

Background This study aims to contribute to peritonitis management strategies by comparing the demographic, clinical, and laboratory characteristics of patients diagnosed with spontaneous bacterial peritonitis (SBP), peritoneal dialysis-related peritonitis (PDrP), and secondary peritonitis. Methods This study included 86 patients diagnosed with peritonitis between 2016 and 2022. Patients were categorized and compared as SBP, PDrP, and secondary peritonitis. Results SBP was diagnosed in 36% of patients, secondary peritonitis in 36% and PDrP in 28%. The mean age of patients with PDrP is 43.71 ± 14.74, which is significantly lower compared to those with SBP and secondary peritonitis (p<0.001). Patients with hypertension (HT), chronic kidney disease (CKD), and those undergoing dialysis most commonly have PDrP whereas those without HT, without CKD, and not undergoing dialysis are most often diagnosed with secondary peritonitis (p=0.002, p<0.001, p<0.001). In peritoneal fluid cultures, the growth of Gram-positive bacteria was most commonly identified in patients with PDrP, while the growth of Gram-negative bacteria was most frequently seen in patients with secondary peritonitis (p=0.018). CRP levels and sedimentation rates were found to be higher in patients with secondary peritonitis (p<0.001, p=0.003). Conclusion The distinct characteristics observed across different types of peritonitis underscore the importance of tailored approaches to diagnosis and treatment. Parameters such as CRP levels, sedimentation rates, and patient age could serve as valuable indicators in discerning between various types of peritonitis. When selecting empirical antibiotic therapy, it's crucial to consider coverage for Gram-positive pathogens in cases of PDrP and Gram-negative pathogens in secondary peritonitis.
