Bacterial profile, drug resistance pattern, clinical and laboratory predictors of ascites infection in cirrhosis patients. BMC Infect Dis 2024; 24:528. [PMID: 38797850 PMCID: PMC11128108 DOI: 10.1186/s12879-024-09418-6] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/03/2024] [Accepted: 05/20/2024] [Indexed: 05/29/2024] Open
Abstract
Ascites is a pathological collection of free fluid in the peritoneal cavity, which is a common complication in patients with cirrhosis, an advanced liver disease. Bacterial infection increases the mortality rate of hospitalized patients with cirrhosis, irrespective of the severity of the liver disease. Around 60% of patients with compensated cirrhosis developed ascites within 10 years during the course of their disease. The in-hospital mortality rate due to spontaneous bacterial peritonitis (SBP) could exceed 90%, but with early diagnosis and prompt antibiotic therapy, this rate has been shown to decrease to 20%. Here, we enrolled adult (age ≥ 18) patients with liver disease with evidence of cirrhosis who developed ascites and assessed the presence of spontaneous ascites fluid infection (SAFI) in these patients. Of the total 218 patients, 22.9% (50/218) develop ascites infection. The liver organ function tests like alanine aminotransferase, aspartate aminotransferase, total bilirubin, and direct bilirubin were found to be significantly (P < 0.05) higher in patients with ascites fluid infection compared to patients with non-ascites fluid infection. Of the gram-negative bacteria, K. pneumonia and E. coli were isolated and found to be 100% resistant to amoxicillin and clavulanate. From the gram-positive bacterial isolates, S. aureus was only resistant to penicillin, whereas Str. viridans was resistant to ceftriaxone, cefotaxime, cefepime, and penicillin. On the other hand, clinical features such as a history of jaundice, low arterial blood pressure, and ultrasound results such as a shrunken liver and enlarged spleen were also independent predictors of spontaneous bacterial peritonitis. In conclusion, given the high probability of death following SAFI, early detection, and treatment, as well as knowledge of the microbial agent, resistance profile, and predictive markers in various contexts, are essential for the timely diagnosis and management of SAFI in these patients.

Abstract
BACKGROUND Recently, a simple scoring system named the Mansoura scoring system was developed to predict spontaneous bacterial peritonitis (SBP) in patients with cirrhosis and ascites. However, the efficacy of this newly developed system has not been extensively investigated. We aimed to validate a new simple scoring system for the rapid diagnosis or exclusion of SBP without paracentesis. METHODS Adult patients with cirrhosis and ascites admitted to Cho Ray Hospital between November 2021 and May 2022 were included. The area under the receiver operating characteristic (AUROC) curve of the Mansoura simple scoring system for predicting SBP was calculated using the Stata software. Other independent laboratory tests for predicting SBP (C-reactive protein [CRP], neutrophil-to-lymphocyte ratio [NLR], and mean platelet volume [MPV]) were assessed and compared using the Mansoura scoring system. RESULTS A total of 121 patients were included in this study. The Mansoura scoring system showed good performance in predicting SBP in patients with cirrhosis and ascites (AUROC:0.89). At the cut-off ≥ 4 points, the scoring system achieved a specificity of 97.7% with a positive predictive value for the diagnosis of SBP of 93.5%. Multivariate analysis was performed using our data and showed that NLR, CRP level, and MPV were independent factors related to SBP. CONCLUSION The Mansoura scoring system demonstrated good performance in predicting SBP in patients with cirrhosis and ascites and may help guide management decisions.

Abstract
INTRODUCTION Spontaneous bacterial peritonitis (SBP) is a common infection in patients with cirrhosis and ascites and is associated with significant risk of mortality. Therefore, it is important for emergency medicine clinicians to be aware of the current evidence regarding the diagnosis and management of this condition. OBJECTIVE This paper evaluates key evidence-based updates concerning SBP for the emergency clinician. DISCUSSION SBP is commonly due to Gram-negative bacteria, but infections due to Gram-positive bacteria and multidrug resistant bacteria are increasing. The typical presentation of SBP includes abdominal pain, worsening ascites, fever, or altered mental status in a patient with known liver disease; however, some patients may be asymptomatic or present with only mild symptoms. Paracentesis is the diagnostic modality of choice and should be performed in any patient with ascites and concern for SBP or upper gastrointestinal bleeding, or in those being admitted for a complication of cirrhosis. Ultrasound should be used to optimize the procedure. An ascites absolute neutrophil count (ANC) ≥ 250 cells/mm3 is diagnostic of SBP. Ascitic fluid should be placed in blood culture bottles to improve the culture yield. Leukocyte esterase reagent strips can be used for rapid diagnosis if available. While many patients will demonstrate coagulation panel abnormalities, routine transfusion is not recommended. Management traditionally includes a third-generation cephalosporin, but specific patient populations may require more broad-spectrum coverage with a carbapenem or piperacillin-tazobactam. Albumin infusion is associated with reduced risk of renal impairment and mortality. CONCLUSIONS An understanding of literature updates can improve the care of patients with suspected SBP.

Abstract
Spontaneous bacterial peritonitis (SBP) is a potentially fatal complication in patients with liver cirrhosis. Early diagnosis and prompt treatment of SBP are vital to shorten hospital stays and reduce mortality. According to society guidelines, patients with cirrhosis and ascites who are admitted to the hospital should have diagnostic paracentesis. However, for various reasons, paracentesis may be delayed or not performed. Therefore, recent research has focused on identifying non-invasive parameters useful in SBP prediction which require urgent antibiotic therapy if rapid and secure paracentesis is not possible or there is insufficient experience with this method. In this review, we discuss the non-invasive methods available to predict SBP.

Abstract
This study is aimed at assessing the distinctive features of patients with infected ascites and liver cirrhosis and developing a scoring system to allow for the accurate identification of patients not requiring abdominocentesis to rule out infected ascites. A total of 700 episodes of patients with decompensated liver cirrhosis undergoing abdominocentesis between 2006 and 2020 were included. Overall, 34 clinical, drug, and laboratory features were evaluated using machine learning to identify key differentiation criteria and integrate them into a point-score model. In total, 11 discriminatory features were selected using a Lasso regression model to establish a point-score model. Considering pre-test probabilities for infected ascites of 10%, 15%, and 25%, the negative and positive predictive values of the point-score model for infected ascites were 98.1%, 97.0%, 94.6% and 14.9%, 21.8%, and 34.5%, respectively. Besides the main model, a simplified model was generated, containing only features that are fast to collect, which revealed similar predictive values. Our point-score model appears to be a promising non-invasive approach to rule out infected ascites in clinical routine with high negative predictive values in patients with hydropic decompensated liver cirrhosis, but further external validation in a prospective study is needed.

Abstract
Background Asplenia or functional hyposplenism are risk factors for severe infections, and vaccinations against encapsulated bacteria are advised. There are only limited data regarding the spleen function of cirrhotic patients. Methods We evaluated spleen function in patients with liver cirrhosis, who were prospectively enrolled in this study. Spleen function was evaluated by the measurement of pitted erythrocytes. Functional hyposplenism was defined as a percentage of PE of >15%. Results 117 patients, mean age 58.4 years and 61.5% (n = 72) male with liver cirrhosis were included. Functional hyposplenism was diagnosed in 28/117 patients (23.9%). Pitted erythrocytes correlated with albumin (p = 0.024), bilirubin (p<0.001), international normalized ratio (INR; p = 0.004), model of end-stage liver disease (MELD) score (p<0.001) and liver stiffness (p = 0.011). Patients with functional hyposplenism had higher MELD scores (median 13 vs. 10; p = 0.021), liver stiffness (46.4 kPa vs. 26.3 kPa; p = 0.011), INR (1.3 vs. 1.2; p = 0.008) and a higher Child-Pugh stage (Child C in 32.1% vs. 11.2%; p = 0.019) as compared to patients without functional hyposplenism. Functional hyposplenism was not associated with the etiology of cirrhosis. Importantly, 9/19 patients with Child C cirrhosis had functional hyposplenism. Conclusion A quarter of patients with liver cirrhosis and almost 50% of patients with Child C cirrhosis have functional hyposplenism. Functional hyposplenism is associated with poor liver function and the degree of portal hypertension, which is characterized by higher liver stiffness measurements in transient elastography.

Abstract
Spontaneous bacterial peritonitis (SBP) is a life-threatening complication in patients with cirrhosis. We aimed to develop an explainable machine learning model to achieve the early prediction and outcome interpretation of SBP. We used CatBoost algorithm to construct MODEL-1 with 46 variables. After dimensionality reduction, we constructed MODEL-2. We calculated and compared the sensitivity and negative predictive value (NPV) of MODEL-1 and MODEL-2. Finally, we used the SHAP (SHapley Additive exPlanations) method to provide insights into the model’s outcome or prediction. MODEL-2 (AUROC: 0.822; 95% confidence interval [CI] 0.783–0.856), liked MODEL-1 (AUROC: 0.822; 95% CI 0.784–0.856), could well predict the risk of SBP in cirrhotic ascites patients. The 6 most influential predictive variables were total protein, C-reactive protein, prothrombin activity, cholinesterase, lymphocyte ratio and apolipoprotein A1. For binary classifier, the sensitivity and NPV of MODEL-1 were 0.894 and 0.885, respectively, while for MODEL-2 they were 0.927 and 0.904, respectively. We applied CatBoost algorithm to establish a practical and explainable prediction model for risk of SBP in cirrhotic patients with ascites. We also identified 6 important variables closely related to the occurrence of SBP.

Abstract
Spontaneous bacterial peritonitis (SBP) is a severe complication of liver cirrhosis whose diagnosis is based on a polymorphonuclear leukocyte (PMN) value >250 mm3, yet this PMN value cannot identify all existing types. The aim of our study was to determine the clinical and biological factors that were associated with SBP and predict its occurrence, focusing on the neutrophil-to-lymphocyte ratio (NLR) as one of them. Our retrospective study included 216 patients with liver cirrhosis who were hospitalized between December 2019 and January 2010 at the Emergency County Clinical Hospital of 'St. Apostle Andrew' in Constanta, Romania. Demographic, clinical, and laboratory data were collected from patient observation sheets. The patients were divided into two groups: One group of patients with SBP and the other without SBP. The diagnosis of SBP was made when patients presented with PMN >250 mm3 and other causes of secondary bacterial peritonitis were excluded. The mean age of the patients was 61.25±10.67 years, and the alcoholic etiology of liver cirrhosis was most common (44%). Univariate logistic regression analysis showed that there was an association between biological parameters, such as serum white blood cells, total platelet count, total bilirubin, serum albumin, international normalized ratio, creatinine, erythrocyte sedimentation rate (ESR), serum sodium, alkaline reserve, and NLR, and clinical parameters, such us upper gastrointestinal bleeding and cardiac comorbidities in the occurrence of SBP. Multivariate analysis identified ESR and NLR as predictive factors in the occurrence of SBP. The area under the curve (AUC) was 0.916 [P<0.001, 95% confidence interval (CI) 0.870-0.949] for ESR and AUC was 0.963 (P<0.001, 95% CI 0.928-0.984) for NLR, respectively. In conclusion, the combination of these 2 biological parameters is useful in identifying or excluding SBP.

Abstract
Thrombocytopenia is a frequent complication in patients with cirrhosis. As many as 84% of patients with cirrhosis have thrombocytopenia, and it is an independent variable indicative of advanced disease and poor prognosis. Although there is great concern that it may aggravate bleeding during surgical procedures, there is limited evidence to inform decisions regarding the treatment of cirrhotic patients with thrombocytopenia undergoing invasive procedures. Finally, there is evidence that platelets play a significant role in liver regeneration. In this report, the clinical implications of thrombocytopenia in cirrhotic patients are reviewed. The utility of platelet counts in the prognosis of cirrhosis and relationship to complications of advanced liver disease, including portal hypertension, esophageal varices, and hepatocellular carcinoma. The impact of low platelet counts on bleeding complications during invasive procedures is outlined. Finally, the role of platelets and potential adverse impact in liver regeneration is reviewed.

Abstract
Abstract
Background
The accurate non-invasive diagnosis of spontaneous bacterial peritonitis (SBP) in patients with decompensated liver cirrhosis has not been achieved yet. The aim of the study was to obtain an unmistakable diagnosis of SBP using a new simple serum bioscore, made by combined measurement of procalcitonin (PCT), erythrocyte sedimentation rate (ESR), and C-reactive protein (CRP), which we called the PEC index. This cross-sectional analytic study comprised 178 cirrhotic patients with ascites (60 patients with SBP and 118 patients with sterile ascites), after excluding non-SBP infection, during the period from March 2019 until September 2019. In all participants, serum levels of PCT, ESR, and CRP were measured, and PEC index was calculated [PEC index = PCT × (ESR + CRP)].
Results
Patients with SBP (n = 60) had significantly higher serum PEC index than those with sterile ascites (n = 118) (41.0/31.2–93.0 vs. 9.9/5.9–15.0, P < 0.001). PEC index distinguished culture positive cases significantly (P < 0.001). Using receiver operating characteristic (ROC) statistics, the sensitivity and specificity of PCT, at a cutoff value of 0.590 ng/mL, for SBP diagnosis, were 81.67% and 93.33%, respectively (area under the curve [AUC] = 0.879; 95% confidence interval [CI] 0.809–0.948). The sensitivity and specificity of ESR, at a cutoff value of 27.0 mm/hour, were 73.33% and 61.67%, respectively (AUC = 0.679; 95% CI 0.581–0.776). The sensitivity and specificity of CRP, at a cutoff value of 21.0 mg/L, were 93.33% and 51.67%, respectively (AUC = 0.736; 95% CI 0.639–0.833). While, the sensitivity and specificity of PEC index, at a cutoff value of 20, were highest (98.33% and 96.67%, respectively, AUC = 0.977; 95% CI 0.940–0.996).
Conclusion
Serum PEC index makes an accurate noninvasive diagnosis of SBP, after excluding other infections.

Model for End-Stage Liver Disease Score Predicts Development of First Episode of Spontaneous Bacterial Peritonitis in Patients With Cirrhosis. Mayo Clin Proc 2019; 94:1799-1806. [PMID: 31400909 PMCID: PMC9709904 DOI: 10.1016/j.mayocp.2019.02.027] [Citation(s) in RCA: 6] [Impact Index Per Article: 1.2] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 10/30/2018] [Revised: 02/13/2019] [Accepted: 02/19/2019] [Indexed: 12/13/2022]
Abstract
OBJECTIVE To examine whether baseline model for end-stage liver disease (MELD) score in patients with cirrhosis and ascites predicts the future development of first spontaneous bacterial peritonitis (SBP) episode. METHODS A retrospective case-control study was performed at three academic centers to select patients admitted with first SBP episode (cases) and those with ascites admitted for decompensation without SBP (controls). Medical records from these centers were reviewed between January 1, 2008, and December 31, 2013. Cases and controls were matched (1:2) for age, sex, and race. Conditional logistic recession models were built to determine whether baseline MELD score (within a month before hospitalization) predicts first SBP episode. RESULTS Of 697 patients (308, 230, and 159 from centers A, B, and C, respectively), cases and controls were matched in 94%, 89%, and 100% at three respective centers. In the pooled sample, probability of SBP was 11%, 31%, 71%, and 93% at baseline MELD scores less than or equal to 10, from 11 to 20, from 21 to 30, and greater than 30, respectively. Compared with MELD score less than or equal to 10, patients with MELD scores from 11 to 20, 21 to 30, and greater than 30 had six- (3- to 11-), 29- (12- to 69-), and 115- (22- to 598-) folds (95% CI) risk of SBP, respectively. Based on different MELD score cutoff points, MELD score greater than 17 was most accurate in predicting SBP occurrence. Analyzing 315 patients (152 cases) with available data on ascitic fluid protein level controlling for age, sex, and center, MELD score but not ascitic fluid protein associated with first SBP episode with respective odds ratios of 1.20 (1.14 to 1.26) and 0.88 (0.70 to 1.11). CONCLUSION Baseline MELD score predicts first SBP episode in patients with cirrhosis and ascites.

Abstract
BACKGROUND AND OBJECTIVE Spontaneous bacterial peritonitis (SBP) is a common bacterial infection with life-threatening sequelae in cirrhotic ascites. The purpose of this retrospective cohort study was to recognize the predictors of SBP to build up a noninvasive system to exclude or establish an episode of SBP. PATIENTS AND METHODS Of 1194 consecutive patients with cirrhotic ascites, only 966 patients were enrolled in this study. SBP was diagnosed once polymorphonuclear count was at least 250 cells/mm and/or there was a positive ascitic fluid culture result. Biochemical and clinical parameters were evaluated as predictors of SBP. A scoring system was established in the training group of 682 and validated in a second group of 284 participants. RESULTS The incidence of SBP was 12.3 and 12% in the training and validation groups, respectively. Age of at least 55 years, mean platelet volume (MPV) of at least 8.5 fl, neutrophil-to-lymphocyte ratio (NLR) of at least 2.5, and C-reactive protein (CRP) of at least 40 mg/l were identified as independent predictors of SBP. A scoring system including these four variables (age, MPV, and NLR with 1 point each, whereas CRP with 2 points) achieves a specificity of 98.2% with a positive predictive value for the diagnosis of SBP of 88.1% (score≥4). At a threshold of 1 point, the negative predictive value is 97.5% with a sensitivity of 92.9%. SBP is not associated with a high Model for End-stage Liver Disease score (P=0.135). CONCLUSION The combination of age, MPV, NLR, and CRP in a simple scoring system, Mansoura simple scoring system, supports quick and accurate exclusion or diagnosis of SBP.

Abstract
Cirrhotic patients with ascites are at high risk of developing spontaneous bacterial peritonitis (SBP). After exclusion of patients with acute kidney injury (AKI) or other infections, urinary neutrophil gelatinase-associated lipocalin (NGAL) levels were compared between two matched groups of Egyptian cirrhotic patients with ascites, mostly secondary to hepatitis C infection (98%). Group 1 had SBP (n = 41) and group 2 did not (n = 45). By univariate analysis, urinary-NGAL, high total bilirubin, serum creatinine, international normalised ratio and the Model of End-Stage Liver Disease (MELD) score and low platelet count were all significantly correlated with the presence of SBP, but only urinary-NGAL could independently predict development of SBP ( P = 0.001). Urinary-NGAL at a cut-off value of 1225 pg/mL, showed a sensitivity of 95% and a specificity of 76%, and is therefore a most useful tool.

Abstract
Background and Aims: Spontaneous bacterial peritonitis (SBP) is a serious complication of liver cirrhosis and a prognostic model to predict it is needed. This study was designed to test the ability of different laboratory tests and the new scoring system by Wehmeyer and colleagues (consisting of age, C-reactive protein (CRP) and platelet count) to predict it. Methods: Three-hundred patients admitted to the National Liver Institute, University of Menoufia, Egypt (2015-2016) with liver cirrhosis and ascites were included in our study. SBP was diagnosed if ascetic neutrophil count was ≥250/µL with no sign of secondary peritonitis. Results: The patient population had age range of 29-81 years old, was 60% men and showed a majority (91.7%) with primary cause of liver disease being hepatitis C. By univariate analysis, associations with age, total bilirubin, aspartate aminotransferase level, creatinine level, international normalized ratio, model for end-stage liver disease score, total leucocytic count, platelet count and CRP level were significant. By multivariate analysis, independent predictors were age, platelet count and CRP level (p = 0.004, 0.013 and <0.001, respectively). CRP at a cut-off point ≥13.5 mg/L could predict SBP (sensitivity of 86.4% and specificity of 66.0%). Wehmeyer's SBP scoring system was predictive (p < 0.001); only 4% of patients with 0 score developed SBP (CRP cut-off of 30 mg/L), while 92.8% with score of 3 or 4 developed SBP. By using our modified Wehmeyer score with CRP cut-off value of 13.5 mg/L, no patient with 0 score developed SBP. Conclusions: Age, CRP level and platelet count are independent predictors for SBP and a scoring system including them could easily predict the condition. SBP diagnosis could be excluded in patients with 0 score, using CRP cut-off value of 13.5 mg/L.

Abstract
BACKGROUND AND AIMS The diagnosis of spontaneous bacterial peritonitis (SBP) depends primarily on a polymorphonuclear leukocyte cell count more than 250/mm. This method is invasive, and not diagnostic in all variants of SBP; we aimed to assess serum homocysteine as a precise indicative marker for the diagnosis of all variants of SBP. PATIENTS AND METHODS A total 323 consecutive ascitic patients were registered in this prospective work. Serum and ascitic fluid of homocysteine were evaluated utilizing an enzyme-linked immunosorbent assay. RESULTS Participants were classified into a non-SBP group, including 262 participants and 61 patients with SBP. Serum and ascitic homocysteine were considerably elevated in the SBP group than in the non-SBP group (17.94±7.57 vs. 11.75±5.68 μmol/l; P<0.001 and 14.70±5.45 vs. 9.75±4.55 μmol/l; P<0.001). At a cutoff value of 17.79 μmol/l, serum homocysteine had 89.3% specificity and 95.1% sensitivity for distinguishing SBP (area under the curve: 0.932) and, at a cutoff value of 16.1 μmol/l, ascitic homocysteine had 84.4% specificity and 92.7% sensitivity for distinguishing SBP (area under the curve: 0.901). Both were positively correlated with the polymorphonuclear count, C-reactive protein, Child-Pugh score, and Model For End-Stage Liver Disease score as well as negatively correlated with the protein content in the ascitic fluid and estimated glomerular filtration rate. After SBP therapy, there was a marked reduction in serum and ascitic homocysteine levels. CONCLUSION This study demonstrates that serum and ascitic homocysteine are considerably higher in SBP participants versus non-SBP patients. Serum homocysteine may provide a reliable and noninvasive diagnostic marker for all variants of SBP.

Abstract
Spontaneous bacterial peritonitis (SBP) has a high mortality rate; early antimicrobial therapy is essential for improving patient outcomes. Given that cirrhotic patients are often coagulopathic, the perceived risk of bleeding may prevent providers from performing a paracentesis and ruling out this potentially deadly disease. We examine the pathophysiology and risk factors for SBP, and current guidelines for its diagnosis and treatment. We then review the time-sensitive nature of performing a paracentesis, and the current controversies and contraindications for performing this procedure in patients at risk for SBP. Cirrhotic patients with ascites and clinical suspicion for SBP-abdominal pain or tenderness, fever or altered mental status-should have a diagnostic paracentesis. Although most patients with cirrhosis and liver dysfunction will have prolonged prothrombin time, paracentesis is not contraindicated. Limited data support platelet administration prior to paracentesis if <40,000-50,000/μL. Timely antimicrobial therapy includes a third-generation cephalosporin for community-acquired infection; nosocomial infections should be treated empirically with a carbapenem or with piperacillin-tazobactam, or based on local susceptibility testing. Patients with gastrointestinal (GI) hemorrhage should receive ceftriaxone prophylactically for GI hemorrhage. SBP has a high mortality rate. Early diagnosis and antimicrobial therapy are essential for improving patient outcomes. Cirrhotic patients with ascites with clinical suspicion for SBP, abdominal pain or tenderness, altered mental status or fever should have a diagnostic paracentesis performed prior to admission unless platelets <40,000-50,000/μL.

Abstract
AIM Tolvaptan, an oral active vasopressin V2 receptor antagonist, is widely used for hepatic edema in Japan, but its clinical benefits have yet to be fully clarified. The present study evaluated the efficacy of tolvaptan in hepatic edema. METHODS The efficacy and treatment regimen of tolvaptan were evaluated in 150 patients with hepatic edema by analyzing the initial (day 14) and long-term (day 90) responses to the drug and their predictive factors. All patients were divided into good (Child-Pugh classification B, and absent of advanced hepatocellular carcinoma) and poor hepatic condition groups, and the response rates were compared between the two groups. RESULTS The initial response rate was 62%, and the long-term response rate was 47%. The assessment of predictive factors for response to tolvaptan showed that serum creatinine and C-reactive protein levels were important predictors of initial response, and that hepatic conditions, such as the Child-Pugh score or presence of hepatocellular carcinoma, as well as initial response, were significant predictors of long-term response. In addition, both the initial and long-term response rates and the cumulative survival rate were found to be higher in the good hepatic condition group than in the poor hepatic condition group, respectively (71% vs. 57%, P = 0.113; 62% vs. 39%, P = 0.009; log-rank test, P < 0.001). CONCLUSION These results suggest that tolvaptan may provide high response rates when used early in the course of hepatic edema, or when both hepatic and renal functions are still retained, leading to an improved disease prognosis.

Abstract
BACKGROUND Spontaneous bacterial peritonitis (SBP) is a known complication of advanced cirrhosis and presents a high mortality rate. A polymorphonuclear (PMN) cell count >250/μl in the ascitic fluid is the current gold standard for diagnosing SBP. AIM We evaluated the accuracy of a point-of-care test (POCT) for ascitic calprotectin in diagnosing patients with SBP. METHODS Eighty-eight patients admitted with decompensation of liver cirrhosis were studied including 41 patients (46.6%) with SBP. Ascitic calprotectin was measured using a quantitative POCT developed by Bühlmann® . RESULTS Calprotectin levels correlated with PMN cell count and other inflammatory markers and were significantly higher in patients with SBP. An optimal cutoff of calprotectin above 1.57 μg/ml presented high sensitivity (87.8%), specificity (97.9%), and positive (97.3%) and negative (90.2%) predictive values for diagnosing SBP. Using calprotectin selectively in patients with a serum albumin-ascites gradient above 11 g/l further increased the sensitivity and negative predictive values of the test. CONCLUSION Ascitic calprotectin appears to be a reliable method for diagnosing SBP in patients with liver cirrhosis. It may present an alternative to other conventional diagnostic methods.

Abstract
Second generation thrombopoietin agonists including eltrombopag and romiplostim act on the thrombopoietin receptor to increase the megakaryocyte production. These agents were needed as use of first generation recombinant products was associated with formation of autoantibodies. Eltrombopag is an oral thrombopoietin agonist found effective in raising platelet counts in patients with immune thrombocytopenia. The drug has now been found to be useful in raising platelet counts in thrombocytopenia related to liver disease including cirrhosis and chronic viral hepatitis. Although the drug may help enable adequate interferon therapy in patients with HCV infection and help carry out invasive procedures in patients with cirrhosis, concerns have been raised of possible thrombotic complications including portal vein thrombosis. Randomized trials have shown that use of eltrombopag concomitant with pegylated interferon and ribavirin increased the chances of sustained virologic response while decreasing the dose reductions of interferon. The data on use of romiplostim in these clinical indications is also emerging. However, in the future, availability of interferon free regimens is likely to decrease the use of eltrombopag for enabling antiviral therapy. The review discusses the role of eltrombopag in management of liver disease related thrombocytopenia in wake of recent data as also the dosage, precautions and adverse effects associated with its use.
