Abstract
Patients with inflammatory liver diseases, particularly alcohol-associated liver disease and metabolic dysfunction-associated fatty liver disease (MAFLD), have higher incidence of infections and mortality rate due to sepsis. The current focus in the development of drugs for MAFLD is the resolution of non-alcoholic steatohepatitis and prevention of progression to cirrhosis. In patients with cirrhosis or alcoholic hepatitis, sepsis is a major cause of death. As the metabolic center and a key immune tissue, liver is the guardian, modifier, and target of sepsis. Septic patients with liver dysfunction have the highest mortality rate compared with other organ dysfunctions. In addition to maintaining metabolic homeostasis, the liver produces and secretes hepatokines and acute phase proteins (APPs) essential in tissue protection, immunomodulation, and coagulation. Inflammatory liver diseases cause profound metabolic disorder and impairment of energy metabolism, liver regeneration, and production/secretion of APPs and hepatokines. Herein, the author reviews the roles of (1) disorders in the metabolism of glucose, fatty acids, ketone bodies, and amino acids as well as the clearance of ammonia and lactate in the pathogenesis of inflammatory liver diseases and sepsis; (2) cytokines/chemokines in inflammatory liver diseases and sepsis; (3) APPs and hepatokines in the protection against tissue injury and infections; and (4) major nuclear receptors/signaling pathways underlying the metabolic disorders and tissue injuries as well as the major drug targets for inflammatory liver diseases and sepsis. Approaches that focus on the liver dysfunction and regeneration will not only treat inflammatory liver diseases but also prevent the development of severe infections and sepsis.

[PMID: 38007536 PMCID: PMC10676395 DOI: 10.1038/s41598-023-44842-9] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/22/2023] [Accepted: 10/12/2023] [Indexed: 11/27/2023] Open
Abstract
Our study aimed to investigate the prognostic value of neutrophil count to albumin ratio (NAR) in predicting short-term mortality of patients with decompensated cirrhosis (DC). A total of 623 DC patients were recruited from a retrospective observational cohort study. They were admitted to our hospital from January 2014 to December 2015. NAR of each patient was calculated and analyzed for the association with 90-day liver transplantation-free (LT-free) outcome. The performance of NAR and the integrated model were tested by a receiver-operator curve (ROC) and C-index. The 90-day LT-free mortality of patients with DC was 10.6%. NAR was significantly higher in 90-day non-survivors than in survivors (The median: 1.73 vs 0.76, P < 0.001). A threshold of 1.40 of NAR differentiated patients with a high risk of death (27.45%) from those with a low risk (5.11%). By multivariate analysis, high NAR was independently associated with poor short-term prognosis (high group: 5.07 (2.78, 9.22)). NAR alone had an area under the ROC curve of 0.794 and C-index of 0.7789 (0.7287, 0.8291) in predicting 90-day mortality. The integrated MELD-NAR (iMELD) model had a higher area under the ROC (0.872) and C-index (0.8558 (0.8122, 0.8994)) than the original MELD in predicting 90-day mortality. NAR can be used as an independent predictor of poor outcomes for patients with DC during short-term follow-up.

Predictive models for sepsis in children with Staphylococcus aureus bloodstream infections: a retrospective cohort study. BMC Pediatr 2023; 23:496. [PMID: 37784062 PMCID: PMC10544563 DOI: 10.1186/s12887-023-04317-2] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 10/06/2022] [Accepted: 09/16/2023] [Indexed: 10/04/2023] Open
Abstract
BACKGROUND The presence of Staphylococcus aureus in the bloodstream can lead to the development of sepsis; however, the severity and risk factors of the systemic inflammatory response to Staphylococcus aureus bloodstream infections were unclear. This study is aimed to build a model to predict the risk of sepsis in children with Staphylococcus aureus bloodstream infections. METHODS A retrospective analysis of hospitalized pediatric patients diagnosed with Staphylococcus aureus bloodstream infections was performed between January 2013 and December 2019. Each patient was assessed using the pediatric version of the Sequential Organ Failure Assessment score (pSOFA) within 24 h of blood culture collection. A nomogram based on logistic regression models was constructed to predict the risk factors for sepsis in children with Staphylococcus aureus bloodstream infections. It was validated using the area under the receiver-operating characteristic curve (AUC). RESULTS Of the 94 patients included in the study, 35 cases (37.2%) developed sepsis. The pSOFA scores ranged from 0 to 8, with 35 patients having a pSOFA score of ≥ 2. Six children (6.4%) died within 30 days, who were all from the sepsis group and had different pSOFA scores. The most common organs involved in sepsis in children with staphylococcal bloodstream infections were the neurologic system (68.6%), respiratory system (48.6%), and coagulation system (45.7%). Hospital-acquired infections (adjusted odds ratio [aOR], 3.0; 95% confidence interval [CI], 1.3-7.2), implanted catheters (aOR, 10.4; 95% CI, 3.8-28.4), procalcitonin level ≥ 1.7 ng/mL (aOR, 15.4; 95% CI, 2.7-87.1), and underlying diseases, especially gastrointestinal malformations (aOR, 14.0; 95% CI, 2.9-66.7) were associated with Staphylococcus aureus sepsis. However, methicillin-resistant Staphylococcus aureus infection was not a risk factor for sepsis. The nomogram had high predictive accuracy for the estimation of sepsis risk, with an AUC of 0.85. CONCLUSIONS We developed a predictive model for sepsis in children with Staphylococcus aureus infection.

Serum C-reactive protein and neutrophil-to-lymphocyte ratio as predictors of survival in cirrhotic patients with systemic inflammatory response syndrome and bacterial infection. Indian J Gastroenterol 2021; 40:265-271. [PMID: 33974227 DOI: 10.1007/s12664-020-01134-8] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 09/04/2019] [Accepted: 11/29/2020] [Indexed: 02/04/2023]
Abstract
BACKGROUND Cirrhotic patients are prone to infections due to underlying immune dysfunction in them. We aimed to study the role of inflammatory markers, serum C-reactive protein (CRP) and neutrophil-to-lymphocyte ratio (NLR), in predicting infection, blood culture positivity, and short-term (1 month) mortality in hospitalized cirrhotic patients. METHODS This prospective study was done over a period of 14 months (October 2017 to November 2018). Patient data included age, gender, etiology of cirrhosis, reason for admission, and comorbidity. Laboratory tests included blood chemistry and blood cell counts, and blood and urine culture. The specific tests included were CRP and NLR. Survival of patients in the following 1 month was noted. Area under receiver operating characteristic curve (AUROC), sensitivity, specificity, predictive values, diagnostic accuracy were calculated and logistic regression analysis performed. A p-value < 0.05 was considered significant. RESULTS Two hundred and eight patients formed the study cohort. The median age was 51.5 years and male predominance was noted. Alcohol-related liver disease (49%) was the commonest etiology. The infection rate was 62%, culture positivity was 58.5%, and mortality was 30.8%. NLR and CRP were significantly higher in those with documented infection (culture positive or negative) and among nonsurvivors. Optimal cutoffs for NLR and CRP to predict infection were 5.86 and 33.7, respectively. The risk of having an infection was 7.5 times and about 15 times if NLR and CRP were above the cutoffs. The risk of 1-month mortality was 2-3 times higher if patients had NLR and CRP above the cutoffs. The combination of NLR and CRP (≥ 5.86 and ≥ 33.7, respectively) increased specificity and diagnostic accuracy for infection. CONCLUSION NLR and CRP were independently good predictors of infection and 1-month survival among the patients with cirrhosis of liver included in this study.

A risk score based on pediatric sequential organ failure assessment predicts 90-day mortality in children with Klebsiella pneumoniae bloodstream infection. BMC Infect Dis 2020; 20:916. [PMID: 33267829 PMCID: PMC7709332 DOI: 10.1186/s12879-020-05644-w] [Citation(s) in RCA: 4] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/06/2020] [Accepted: 11/22/2020] [Indexed: 12/31/2022] Open
Abstract
Background Klebsiella pneumoniae bloodstream infection (Kp-BSI) is a serious threat to pediatric patients. The objective of this study was to explore the risk factors, validate the prediction efficiency of pediatric Sequential Organ Failure Assessment (SOFA) and establish better early predictors of mortality in pediatric patients with Kp-BSI. Methods All children diagnosed with Kp-BSI were included in this retrospective cohort study from January 2009 to June 2019. Basic characteristics, symptoms and physical examinations, treatments, laboratory statistics, and SOFA at the onset of Kp-BSI were recorded. The Cox proportional hazard model and receiver operating characteristic curves were used to assess the association between the variables and the 90-day mortality and their predictive value. DeLong’s test of receiver operating characteristic curves and integrated discrimination improvement index were used to determine the improvement in predictive capacity of the modified SOFA models. A predictive score was developed using multivariate logistic regression. Results Of the 146 children enrolled, 33 (22.6%) patients died within 90 days. Hospitalization in the last 6 months, intra-abdominal source of infection, presence of organ failure, and altered levels of blood biomarkers, including C-reactive protein, albumin, and lactate were significant risk factors for 90-day mortality. The area under the curve (AUC) of SOFA for predicting 90-day mortality was 0.80 (95% CI 0.71–0.89). Moreover, we found that a prediction model combining SOFA with two other parameters, namely hospitalization in the last 6 months and intra-abdominal source of infection, was better at predicting mortality (AUC = 0.89, 95% CI 0.82–0.96; sensitivity = 0.86; specificity = 0.84). According to this novel risk model, we defined three statistically different groups: low-risk, medium-risk and high-risk groups, with an observed 90-day mortality of 5.4, 35.7, and 72.0%, respectively. With reference to the low-risk patients, the medium-risk and high-risk groups had a higher mortality, with hazard ratios of 8.36 (95% CI 3.60–27.83) and 20.27 (95% CI 7.47–54.95), respectively. Conclusions The modified SOFA may be better than the original score to predict 90-day mortality in pediatric patients with Kp-BSI. Future prospective studies are required to validate this novel scoring system in external cohorts.

Fluid Biomarkers for Predicting the Prognosis of Liver Cirrhosis. BIOMED RESEARCH INTERNATIONAL 2020; 2020:7170457.

Abstract
Liver cirrhosis is the terminal stage of most chronic liver conditions, with a high risk of mortality. Careful evaluation of the prognosis of cirrhotic patients and providing precise management are crucial to reduce the risk of mortality. Although the liver biopsy and hepatic venous pressure gradient (HVPG) can efficiently evaluate the prognosis of cirrhotic patients, their application is limited due to the invasion procedures. Child-Pugh score and the model for end-stage liver disease (MELD) score had been widely used in the assessment of cirrhotic prognosis, but the defects of subjective variable application in Child-Pugh score and unsuitability to all phases of liver cirrhosis in MELD score limit their prognostic values. In recent years, continuous efforts have been made to investigate the prognostic value of body fluid biomarkers for cirrhotic patients, and promising results have been reported. Since the collection of fluid specimens is easy, noninvasive, and repeatable, fluid biomarkers can be ideal indicators to predict the prognosis of cirrhosis. Here, we reviewed noninvasive fluid biomarkers in different prognostic functions, including the prediction of survival and complication development.

Abstract
BACKGROUND AND AIM This study aims to determine the performance of models adding C-reactive protein (CRP) and procalcitonin (PCT) to the model of end-stage liver disease (MELD) score for mortality prediction in patients hospitalized with complications of cirrhosis. METHODS A prospective cohort study was carried out in consecutive cirrhotic patients admitted with complications of cirrhosis between September 2012 and December 2013 at Phramongkutklao Hospital, Bangkok, Thailand. All patients had venous CRP, PCT, and laboratory values for MELD score calculation measured at emergency room or admission. Cox regression analysis and the c-statistic were used to predict mortality. The MELD-CRP score was externally validated in 818 eligible patients from Mayo Clinic, Rochester, using data from 1288 cirrhotic patients diagnosed between 2010 and 2014. RESULTS A cohort of 177 patients with cirrhosis was admitted during the study period. Seventy-one patients were eligible for analysis. The MELD score was predictive of 90-day mortality odds ratio (OR) 1.19 (95% confidence interval [CI] 1.09-1.32). Adding CRP and/or PCT to the MELD score improved the predictive of 90-day mortality: MELD-CRP OR 2.71 (95% CI 1.66-4.99); MELD-PCT OR 2.72 (95% CI 1.66-4.99); MELD-CRP-PCT OR 2.71 (95% CI 1.67-4.92). The c-statistics for MELD, MELD-CRP, MELD-PCT, and MELD-CRP-PCT were 0.81, 0.83, 0.84, and 0.85, respectively. Adding CRP and/or PCT to the MELD score also improved 30-day mortality prediction. Similar results for the MELD-CRP score were obtained from the Mayo Clinic external validation cohort. CONCLUSION The MELD-CRP, MELD-PCT, and MELD-CRP-PCT scores may be superior to the MELD score alone in predicting mortality in patients hospitalized with complications of cirrhosis.

Abstract
BACKGROUND There is a need for a better understanding of the role of C-reactive protein (CRP) as a valid marker for the detection of bacterial infections in critically immunosuppressed patients. A high negative predictive value of CRP is also needed to rule out sepsis and bacterial infections in immunocompetent patients. However, few studies have evaluated the performance of CRP in immunocompromised hosts. The aim of the present study was to evaluate the performance of CRP as a marker of infection in critically immunosuppressed patients. METHODS The inclusion criterion was immunosuppression for which CRP was used as a bacterial infection marker. Searches were performed in the Cochrane Register, MEDLINE, EMBASE, SCOPUS, Web OF Science, LILACS and CINAHL databases. We applied the Quality Assessment of Diagnostic Accuracy Studies tool 2 (QUADAS 2) to evaluate the quality of the articles and evaluated the test accuracy parameters using hierarchical summary receiver operating characteristic (HSROC) curves and bivariate random effect models. RESULTS Only 13 of 21 studies produced quantitative results. We analyzed all studies using the random effects method (restricted maximum likelihood) and obtained a joint diagnostic odds ratio (DOR) of 3.04 (95% confidence interval [CI] 1.71-5.40) with heterogeneity (I2=91%, Q=181.48, p<0.001). Therefore, a bivariate model was applied. Analyzing the tuberculosis carrier, steroid user, or presence of opportunistic infection subgroups, as described in the proposal, was not possible due to the lack of information on these topics included in the articles. CONCLUSIONS CRP appears to be a good screening tool for sepsis in critically immunosuppressed patients. Submitted PROSPERO 2015: CRD42015019329.

Abstract
AIM To evaluate the diagnostic and prognostic value of presepsin in cirrhosis-associated bacterial infections.
METHODS Two hundred and sixteen patients with cirrhosis were enrolled. At admission, the presence of bacterial infections and level of plasma presepsin, serum C-reactive protein (CRP) and procalcitonin (PCT) were evaluated. Patients were followed for three months to assess the possible association between presepsin level and short-term mortality.
RESULTS Present 34.7 of patients had bacterial infection. Presepsin levels were significantly higher in patients with infection than without (median, 1002 pg/mL vs 477 pg/mL, P < 0.001), increasing with the severity of infection [organ failure (OF): Yes vs No, 2358 pg/mL vs 710 pg/mL, P < 0.001]. Diagnostic accuracy of presepsin for severe infections was similar to PCT and superior to CRP (AUC-ROC: 0.85, 0.85 and 0.66, respectively, P = NS for presepsin vs PCT and P < 0.01 for presepsin vs CRP). At the optimal cut-off value of presepsin > 1206 pg/mL sensitivity, specificity, positive predictive values and negative predictive values were as follows: 87.5%, 74.5%, 61.8% and 92.7%. The accuracy of presepsin, however, decreased in advanced stage of the disease or in the presence of renal failure, most probably because of the significantly elevated presepsin levels in non-infected patients. 28-d mortality rate was higher among patients with > 1277 pg/mL compared to those with ≤ 1277 pg/mL (46.9% vs 11.6%, P < 0.001). In a binary logistic regression analysis, however, only PCT (OR = 1.81, 95%CI: 1.09-3.01, P = 0.022) but neither presepsin nor CRP were independent risk factor for 28-d mortality after adjusting with MELD score and leukocyte count.
CONCLUSION Presepsin is a valuable new biomarker for defining severe infections in cirrhosis, proving same efficacy as PCT. However, it is not a useful marker of short-term mortality.

Abstract
INTRODUCTION C-Reactive Protein (CRP) is an acute phase reactant. Its level increases in the presence of acute or chronic inflammation and infections. High sensitive CRP (hs-CRP) is more sensitive than CRP as an inflammatory marker. High sensitive CRP has been known to be elevated in chronic liver diseases and Spontaneous Bacterial Peritonitis (SBP). AIM The aim of the study was to establish the role of ascitic fluid high sensitive C-reactive protein (hs -CRP) as a prognostic indicator in patients with SBP. MATERIALS AND METHODS A total of 100 patients with decompensated cirrhosis admitted in medicine ward and ICU were included, of which 50 patients of acute bacterial peritonitis were used as study group and 50 patients of sterile ascites were used as control group. Hs-CRP level of cases and controls were estimated. SBP cases were treated with its standard recommended antibiotic therapy and hs-CRP level was again estimated after 5 days of antibiotic therapy or at the time of discharge. RESULTS The mean level of hs-CRP before antibiotic therapy of the patients with SBP was significantly higher than that of the patients without spontaneous bacterial peritonitis (t98=17.72; p=0.0001). The mean level of hs-CRP at 5(th) day or discharge after initiation of antibiotic therapy was significantly lower than that of level of hs-CRP before initiation of antibiotic therapy (p<0.05). The mean hs-CRP of the cases with poor outcome (death and prolonged hospital stay) was significantly higher than others. CONCLUSION Ascitic fluid hs-CRP level can be considered as a surrogate prognostic marker in cases of Cirrhosis with SBP.

Abstract
I dentifying cirrhosis with a poor short-term prognosis remains crucial for improving the allocation of liver grafts. The purpose of this study was to assess the prognostic value of a model combining the variation of C-reactive protein (CRP) levels within 15 days, the Model for End-Stage Liver Disease (MELD) score, and the presence of comorbidities in patients with decompensated cirrhosis with a Child-Pugh score > B7 and to test the relevance of this model in patients with compensated cirrhosis. We collected data for cirrhotic patients without hepatocellular carcinoma, extrahepatic malignancy, human immunodeficiency virus infection, organ transplantation, seen between January 2010 and December 2011. Multivariate analyses of predictors of 3-month mortality used Cox models adjusted with the age-adjusted Charlson comorbidity index. The prognostic performance [area under receiver operating characteristic curves (AUROCs)] of the 3-variable model was compared to that of the MELD score. The 241 patients who met the inclusion criteria included 109 patients with a Child-Pugh score > B7 who were hospitalized for decompensation. In these patients with severe cases, the 3-month mortality was independently predicted by the MELD score [hazard ratio (HR), 1.10; 95% confidence interval (CI), 1.05-1.14; P < 0.001] and a CRP level > 32 mg/L at the baseline and on day 15 (HR, 2.21; 95% CI, 1.03-4.76; P = 0.042). This model was better than MELD alone (AUROC, 0.789 versus 0.734; P = 0.043). In the whole population with cirrhosis, the 3-month mortality was also predicted by high MELD scores (HR, 1.11; 95% CI, 1.07-1.16; P < 0.001) and a CRP level > 10 mg/L at the baseline and on day 15 (HR, 2.89; 95% CI, 1.29-6.48; P < 0.001), but the AUROCs of the 3-variable model and the MELD score alone were no longer significantly different (0.89 versus 0.88, not significant). In conclusion, prognostic models incorporating variations in CRP predict 3-month mortality in patients with cirrhosis. Such models are particularly relevant for patients with decompensated cirrhosis but provide a limited increase in prediction in comparison with the MELD score in the whole population with cirrhosis.

Abstract
In the general population, C-reactive protein (CRP) level increases in the presence of acute or chronic inflammation and infections. In patients with cirrhosis, the basal level is higher than in patients without cirrhosis, due to chronic hepatic and other inflammation, but when infection occurs the more severe the underlying liver dysfunction, the lower the increase in CRP. Therefore, the predictive power of CRP for infection and prognosis is weak in patients with decompensated/advanced cirrhosis and in the intensive care setting. However, higher CRP and also persistently elevated CRP levels can help identify patients with a higher short-term risk of mortality.

Abstract
INTRODUCTION Bacterial infection is a frequent complication in patients with decompensated liver cirrhosis and is related to high mortality rates during follow-up of these individuals. We sought to evaluate the diagnostic value of C-reactive protein (CRP) and procalcitonin (PCT) in diagnosing infection and to investigate the relationship between these biomarkers and mortality after hospital admission. MATERIAL AND METHODS Prospective study that included cirrhotic patients admitted to the hospital due to complications of the disease. The diagnostic accuracy of CRP and PCT for the diagnosis of infection was evaluated by estimating the sensitivity and specificity and by measuring the area under the receiver operating characteristics curve (AUROC). RESULTS A total of 64 patients and 81 hospitalizations were analyzed during the study. The mean age was 54.31 ± 11.87 years with male predominance (68.8%). Significantly higher median CRP and PCT levels were observed among infected patients (P < 0.001). The AUROC of CRP and PCT for the diagnosis of infection were 0.835 ± 0.052 and 0.860 ± 0.047, respectively (P = 0.273). CRP levels > 29.5 exhibited sensitivity of 82% and specificity of 81% for the diagnosis of bacterial infection. Similarly, PCT levels > 1.10 showed sensitivity of 67% and specificity of 90%. Significantly higher levels of CRP (P = 0.026) and PCT (P = 0.001) were observed among those who died within three months after admission. CONCLUSION CRP and PCT were reliable markers of bacterial infection in subjects admitted due to complications of liver cirrhosis and higher levels of these tests are related to short-term mortality in those patients.

Abstract
BACKGROUND Acute pyelonephritis (APN) is one of the most common community-acquired infections and frequently accompanies bacteremia. The purpose of this study was to investigate the diagnostic role of procalcitonin in predicting bacteremia in patients with APN. METHODS We conducted a retrospective study of patients with APN who visited the emergency department (ED) at Samsung Medical Center, Seoul. Predictors of bacteremia were analyzed and receiver operating characteristics (ROC) curves were plotted for procalcitonin, C-reactive protein (CRP), and leukocytes. RESULTS During the study period, a total of 147 patients who had microbiologically proven APN and available initial procalcitonin concentrations were identified. Of these, bacteremia was present in 84 patients. Multivariate analysis showed that age, hypotension, and higher procalcitonin concentrations independently predicted the presence of bacteremia. Procalcitonin had better discriminative power than CRP, as reflected by area under the ROC curve analysis (0.746 [95% CI, 0.667-0.826] vs. 0.602 [95% CI, 0.509-0.694], p = 0.02). At a cut-off value of 1.63 μg/L, procalcitonin predicted bacteremia with a sensitivity, specificity, positive predictive value, negative predictive value and accuracy of 61.9, 81.0, 81.3, 61.4 and 70.1%, respectively. CONCLUSION Procalcitonin concentration could be used as a reliable marker to predict bacteremia in patients with APN in the ED.
