Nie Y, Zeng Y. Clinical characteristics, risk factor analysis and peripheral blood cell changes for early warning of multidrug-resistant bacteria (MDR) infection in elderly patients. Immun Inflamm Dis 2024; 12:e1347. [PMID: 39023415 PMCID: PMC11256884 DOI: 10.1002/iid3.1347] [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] [Revised: 07/01/2024] [Accepted: 07/06/2024] [Indexed: 07/20/2024] Open
Abstract
OBJECTIVE To explore peripheral blood indicators that may serve as early indicators for multidrug-resistant bacteria (MDR) infections in this demographic, with the goal of providing reference suggestions for the clinical prevention of MDR infections in elderly inpatients. METHODS Clinical data of patients were divided into the MDR-infected group (n = 488) and the MDR-uninfected group (n = 233) according to the results of drug sensitivity experiments, risk factors for MDR infection, and peripheral blood indicators related to MDR infections were analyzed using univariate and multivariate logistic regression in conjunction with the construction of a Chi-squared automatic interaction detector (CHAID) decision tree model, considering statistical significance at p < .05. RESULTS Of 721 patients, 488 multidrug-resistant strains were identified. Among them, with Staphylococcus spp. the most prevalent in 148 strains. The most frequent detection of MDR occurred in puncture fluid samples (167 cases). Univariate and multivariate regression analyses revealed that prolonged hospitalization, use of antibiotics preadmission, duration of antibiotics, invasive procedures or recent surgery, and coexisting lung disease were independent risk factors for contracting MDR. Subsequent analysis comparing the aforementioned influences with peripheral blood cells revealed associations between the number of antibiotic treatment days and increased neutrophil-to-lymphocyte ratio (NLR), platelet count-to-lymphocyte ratio (PLR), neutrophils, decreased lymphocytes, and increased eosinophils; preadmission antibiotic use correlated with increased PLR, NLR, neutrophils, and decreased lymphocytes; and invasive manipulation or surgery correlated with increased PLR and NLR. CONCLUSIONS Elevated NLR, PLR, neutrophils, lowered lymphocytes, and eosinophils may serve as early indicators of MDR infections in elderly hospitalized patients.

Abstract
Liver cirrhosis patients are highly susceptible to infections, affecting survival, but current parameters for detecting infection are not reliable enough in this population. We investigated the ability of white blood cell (WBC), ∆WBC, neutrophil and ∆neutrophil counts, neutrophil-to-lymphocyte (NLR) and ∆NLR ratios and C-reactive protein (CRP) and procalcitonin (PCT) levels to identify infection and predict short-term mortality in liver cirrhosis patients. We recruited 233 patients with liver cirrhosis hospitalized with acute decompensation (AD) who had an outpatient visit within 1 month (baseline laboratory data) and followed them for 90 days. Difference between laboratory values at baseline and the AD episode was defined as delta (∆) values of the parameters. Delta values did not increase the diagnostic and predictive ability of investigated parameters. The CRP level was found to be the best diagnostic marker for infection in patients with cirrhosis. However, NLR seems to be superior for short-term mortality prediction, better than the WBC count. Distinguishing inflammations of different origin is a remaining clinical challenge in acutely decompensated cirrhosis. Based on our results, NLR might be more suitable for predicting short-term mortality in patients with AD than the WBC count currently included in the CLIF-C AD score.

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
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.

Assessment of neutrophil subsets and immune checkpoint inhibitor expressions on T lymphocytes in liver transplantation: A preliminary study beyond the neutrophil-lymphocyte ratio. Front Physiol 2023; 14:1095723. [PMID: 37064910 PMCID: PMC10097891 DOI: 10.3389/fphys.2023.1095723] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/11/2022] [Accepted: 03/17/2023] [Indexed: 04/18/2023] Open
Abstract
Background: Advanced stages of cirrhosis are characterized by the occurrence of progressive immune alterations known as CAID (Cirrhosis Associated Immune Dysfunction). In advanced cirrhosis, liver transplantation (LT) remains the only curative treatment. Sepsis, shares many similarities with decompensated cirrhosis in terms of immuno-inflammatory response. In both conditions, the neutrophil-lymphocyte ratio (NLR) is associated with poor outcomes. Based on alterations in sepsis, we hypothesized that we could observe in cirrhotic and LT patients more detailed neutrophil and lymphocyte phenotypes. To this end, along with leukocyte count, we assessed immature neutrophils, LOX-1+ MDSC and PD-1 and TIM-3 lymphocyte expressions in cirrhotic patients before transplantation in association with liver disease severity and during the first month after transplantation. Methods: We conducted a prospective monocentric study including cirrhotic patients registered on LT waiting-list. Blood samples were collected at enrolment before LT and for 1 month post-LT. In addition to NLR, we assessed by whole blood flow cytometry the absolute count of immature neutrophils and LOX-1+ MDSC as well as the expressions of immune checkpoint receptors PD-1 and TIM-3 on T lymphocytes. Results: We included 15 healthy volunteers (HV) and 28 patients. LT was performed for 13 patients. Pre-LT patients presented with a higher NLR compared to HV and NLR was associated with cirrhosis severity. Increased immature neutrophils and LOX-1+ MDSC counts were observed in the most severe patients. These alterations were mainly associated with acute decompensation of cirrhosis. PD-1 and TIM-3 expressions on T lymphocytes were not different between patients and HV. Post-LT immune alterations were dominated by a transitory but tremendous increase of NLR and immature neutrophils during the first days post-LT. Then, immune checkpoint receptors and LOX-1+ MDSC tended to be overexpressed by the second week after surgery. Conclusion: The present study showed that NLR, immature neutrophils and LOX-1+ MDSC counts along with T lymphocyte count and checkpoint inhibitor expression were altered in cirrhotic patients before and after LT. These data illustrate the potential interest of immune monitoring of cirrhotic patients in the context of LT in order to better define risk of sepsis. For this purpose, larger cohorts of patients are now necessary in order to move forward a more personalised care of LT patients.

Neutrophil to Lymphocyte Ratio and Spontaneous Bacterial Peritonitis among Cirrhotic Patients: A Systematic Review and Meta-analysis. Can J Gastroenterol Hepatol 2022; 2022:8604060. [PMID: 36204262 PMCID: PMC9532151 DOI: 10.1155/2022/8604060] [Citation(s) in RCA: 7] [Impact Index Per Article: 3.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 07/11/2022] [Accepted: 08/22/2022] [Indexed: 11/17/2022] Open
Abstract
BACKGROUND The goal of this systematic review and meta-analysis was analyzing published studies on the role of neutrophil to lymphocyte ratio (NLR) in infection and spatially spontaneous bacterial peritonitis (SBP) among cirrhotic patients. METHODS PubMed, Web of Science, and Scopus were searched until May 24, 2022. The Newcastle-Ottawa scale was used for quality assessment. RESULTS Of 14 studies included in our study, six studies were on infection with 2786 hospitalized cirrhotic patients, of whom 934 developed an infection. Other studies were on SBP with 1573 cirrhotic patients with ascites, of whom 557 developed SBP. The pooled results showed that there was no difference in NLR levels between hospitalized cirrhotic patients who developed infection compared to those who did not (random-effects model: SMD = 0.63, 95% CI = -0.01-1.27, p=0.054). However, cirrhotic patients with ascites who developed SBP had elevated levels of NLR compared to those who did not (random-effects model: SMD = 1.05, 95% CI = 0.52-1.57,p < 0.001). This difference remained significant in prospective studies (SMD = 0.94, 95% CI = 0.51-1.38,p < 0.001) but not in retrospective studies (SMD = 1.37, 95% CI = -0.56-3.29,p=0.165), in the subgroup analysis according to the study design. The pooled sensitivity of NLR was 92.07% (95% CI = 74.85%-97.84%) and the pooled specificity was 72.58% (95% CI = 57.72%-83.69%). The pooled positive likelihood ratio, negative likelihood ratio, DOR of NLR were 3.35(95%CI = 2.06-5.46), 0.10 (95%CI = 0.03-0.38), and 30.78 (95%CI = 7.01-135.04), respectively. CONCLUSION Our results support NLR to be a valid biomarker that can be readily integrated into clinical settings to help in the prevention and prediction of SBP among cirrhotic patients.

Abstract
Major depressive disorder (MDD) and bipolar disorders (BDs), the most severe types of mood disorders (MDs), are considered as among the most disabling illnesses worldwide. Several studies suggested that inflammatory neuroinflammation might be involved in the pathophysiology of MDs, while reporting increasing data on the relationships between these processes and classical neurotransmitters, hypothalamus-pituitary-adrenal axis (HPA), and neurotrophic factors. The assessment of neutrophil/lymphocyte ratio (NLR), platelet/lymphocyte ratio (PLR) and monocyte/lymphocyte ratio (MLR) in peripheral blood represents a simple method to evaluate the inflammatory status. The aim of the present paper was to review the literature on the possible relationships between NLR, PLR and MLR in MDs, and to comment on their possible wider use in clinical research. Thirty-five studies were included in the present review. The majority of them higher values of these parameters, particularly NLR values, in patients with MDs, when compared to healthy subjects. The increase would appear more robust in patients with BD during a manic episode, thus indicating that it could be considered as both state and trait markers. In addition, increased NLR and PLR levels seem to represent prognostic elements for the early discovery of post-stroke depression. The findings of the present review would indicate the need to carry our further studies in this field. In particular, NLR, PLR and MLR seem to be promising tools to detect economically and easily the activation of the inflammatory system, and to perhaps evaluate the etiology and course of MDs. Again, they could suggest some information to better understand the relationship between inflammatory and cardiovascular disease and MDs, and thus, to provide clinical implications in terms of management and treatment.

Abstract
BACKGROUND Individuals with cirrhosis have a chronic systemic inflammation associated with an immune dysfunction, affecting the progression of the liver disease. The neutrophil-lymphocyte ratio (NLR) was proposed as a marker of systemic inflammatory response and survival in patients with cirrhosis. OBJECTIVE Evaluate the prognostic role of NLR in cirrhotic patients and its relation with inflammatory cytokines(IL-6, IL-10 and IL-17). METHODS In this prospective study two groups were evaluated: 1) Stable cirrhotic in outpatient follow-up (n=193); 2) Hospitalized cirrhotic for acute decompensation for at least 48 hours (n=334) with admission and 48 hours tests evaluation. Circulating inflammatory cytokines were available for 130 hospitalized patients. RESULTS In outpatients with stable cirrhosis, NLR correlated with MELD score and other variables associated with severity of disease. However, after a median of 32 months of follow up NLR was not associated with mortality (HR 1.058, 95%CI 0.900-1.243; P=0.495). In hospitalized patients, NLR at 48-hour after admission was independently associated with 90-day survival (HR 1.061, 95%CI 1.020-1.103; P=0.003) in multivariate Cox-regression analysis. The 90-day Kaplan-Meier survival probability was 87% for patients with a 48-hour NLR <3.6 and 62% for NLR ≥3.6 (P<0.001). Elevation of NLR in the first 48 hours was also independently associated with mortality (HR 2.038, 95%CI 1295-3207; P=0.002). The 90-day Kaplan-Meier survival probability was 83% when NLR did not increase and 62% when NLR increased (P<0.001). IL-6, IL-10 and IL-17 at admission were positively correlated with both admission and 48-hour NLR. Lower levels of baseline IL-10 were associated with NLR increase during first 48-hour. CONCLUSION NLR evaluated at 48 hours of hospitalization and its early increase after admission were independently associated with short-term mortality in patients hospitalized for acute decompensation of cirrhosis.

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.

[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.

Abstract
BACKGROUND Early diagnosing bacterial infection in cirrhotic patients is critical but challenging. Neutrophil-to-lymphocyte ratio (NLR) reflects systemic inflammation and is an emerging biomarker that replicates cirrhosis' imbalanced immune response. AIM Assess whether NLR levels associate with higher risk of infection in patients admitted with first cirrhosis decompensation. METHODS Retrospective, unicenter study, including patients with cirrhosis, admitted to the hospital at first decompensation. NLR was calculated at admission. Applying logistic regression models and testing for discriminative power, we correlated NLR with the outcome infection. RESULTS We included 139 patients. Forty-four infections to report (31.7%), 18 (12.9%) community infections and 26 (18.7%) hospital-acquired infections.Higher NLR values at admission were associated with increased infection risk in univariable and multivariable models - for each unit increase of NLR, infection odds increased 1.29 times (95%CI = 1.09-1.53; p = 0.003), after adjusting for covariates. We performed a classification tree based only on NLR to evaluate the risk of infection. A high-risk group (proportion of patients with infection = 87%) was identified, corresponding to NLR>14; patients with NLR <3.6 presented lower infection risk (17%).Regarding hospital-acquired infection, we were not able to discriminate groups of patients based on classification trees. CONCLUSION NLR is a straightforward approach to attest the individual infection risk on cirrhotic patients. We report NLR cutoffs 3.6 and 14 as optimal for overall infection diagnosing, mainly due to community infection.

Abstract
PURPOSE Although the neutrophil-lymphocyte ratio (NLR) is a simple biomarker for inflammation, its diagnostic value for predicting surgical site infection (SSI) after spinal decompression surgery has not been extensively investigated. We aimed to determine the predictive value of NLR for SSI in patients undergoing spinal decompression surgery. METHODS We performed a retrospective observational study of patients who underwent spinal decompression surgery. Consecutive 254 patients were divided into an SSI group and a non-SSI group based on the presence of SSI. We evaluated which markers, including NLR, differed significantly between groups. We then determined the diagnostic cutoff values of these markers for the prediction of SSI based on the significance in the univariate analysis. RESULTS The incidence of SSI was 7 of 254 patients (2.8%). Univariate analysis showed that there were significant differences in the C-reactive protein (CRP) level at 1 day postoperatively; neutrophil and lymphocyte percentage and NLR at 3-4 days postoperatively; and CRP level, white blood cell count, neutrophil count and percentage, lymphocyte percentage, and NLR at 6-7 days postoperatively between SSI and non-SSI groups. Among these markers, the cutoff values of lymphocyte percentage and NLR at 3-4 days postoperatively for the prediction of SSI were ≤15.1% and ≥4.91, respectively. The cutoff values of lymphocyte percentage and NLR at 6-7 days postoperatively were ≤19.8% and ≥3.21, respectively. CONCLUSIONS Lymphocyte percentage and NLR at 3-4 and 6-7 days postoperatively were useful markers for the early prediction of SSI in patients who had undergone spinal decompression surgery. These parameters may aid in identifying patients at higher risk of SSI after spinal decompression surgery.

Abstract
BACKGROUND Seeking potentially novel blood markers of liver fibrosis and steatosis is constantly of crucial importance. Despite a growing number of studies in this field of hepatology, a certain role of hematological indices in the course of liver disorders has not been fully elucidated, yet.
AIM To evaluate a diagnostic accuracy of neutrophil-to-lymphocyte ratio (NLR), platelet-to-lymphocyte ratio (PLR) and mean platelet volume-to-platelet-ratio (MPR) in the course of alcoholic liver cirrhosis (ALC) and nonalcoholic fatty liver disease (NAFLD).
METHODS One hundred forty-two patients with ALC, 92 with NAFLD and 68 persons in control group were enrolled in the study. Hematological indices (NLR, PLR and MPR), indirect and direct markers of liver fibrosis (aspartate transaminase to alkaline transaminase ratio, aspartate transaminase to platelet ratio index, fibrosis-4, gamma-glutamyl transpeptidase to platelet ratio, procollagen I carboxyterminal propeptide, procollagen III aminoterminal propeptide, transforming growth factor-α, platelet-derived growth factor AB, laminin) were measured in each person. Model for end-stage liver disease (MELD) score in ALC group and NAFLD fibrosis score together with BARD score were calculated in NAFLD patients. Receiver operating characteristic (ROC) curves and area under the curve (AUC) values were applied to assess the sensitivity and specificity of examined markers and to evaluate proposed cut-offs of measured indices in the course of ALC and NAFLD.
RESULTS MPR and NLR values in ALC patients were significantly higher in comparison to control group; PLR level was significantly lower. MPR and PLR correlated with assessed indirect and direct markers of liver fibrosis. MPR, NLR and PLR correlated with MELD score. NLR level in NAFLD patients was significantly higher in comparison to controls. MPR correlated with indirect markers of liver fibrosis and NAFLD fibrosis score. AUC values and proposed cut-offs for NLR, PLR and MPR in ALC patients were: 0.821 (> 2.227), 0.675 (< 70.445) and 0.929 (> 0.048), respectively. AUC values and proposed cut-offs for NLR, PLR and MPR in NAFLD group were: 0.725 (> 2.034), 0.528 (> 97.101) and 0.547 (> 0.038), respectively.
CONCLUSION Hematological markers are inseparably connected with serological indices of liver fibrosis in ALC and NAFLD patients. MPR and NLR turned out to be the most powerful parameters in ALC patients.

Abstract
BACKGROUND Hepatocellular carcinoma (HCC) is a frequent cause of cancer related death globally. Neutrophil to lymphocyte ratio (NLR) and albumin bilirubin (ALBI) grade are emerging prognostic indicators in HCC.
AIM To study published literature of NLR and ALBI over the last five years, and to validate NLR and ALBI locally in our centre as indicators of HCC survival.
METHODS A systematic review of the published literature on PubMed of NLR and ALBI in HCC over the last five years. The search followed the guidelines of the preferred reporting items for systematic reviews and meta-analyses. Additionally, we also investigated HCC cases between December 2013 and December 2018 in our centre.
RESULTS There were 54 studies describing the relation between HCC and NLR and 95 studies describing the relation between HCC and ALBI grade over the last five years. Our local cohort of patients showed NLR to have a significant negative relationship to survival (P = 0.011). There was also significant inverse relationship between the size of the largest HCC nodule and survival (P = 0.009). Median survival with alpha fetoprotein (AFP) < 10 KU/L was 20 mo and with AFP > 10 KU/L was 5 mo. We found that AFP was inversely related to survival, this relationship was not statically significant (P = 0.132). Mean survival for ALBI grade 1 was 37.7 mo, ALBI grade 2 was 13.4 months and ALBI grade 3 was 4.5 mo. ALBI grades performed better than Child Turcotte Pugh score in detecting death from HCC.
CONCLUSION NLR and ALBI grade in HCC predict survival better than the conventional alpha fetoprotein. ALBI grade performs better than Child Turcotte Pugh score. These markers are done as part of routine clinical care and in cases of normal alpha fetoprotein, these markers could give a better understanding of the patient disease progression. NLR and ALBI grade could have a role in modified easier to learn staging and prognostic systems for HCC.

Abstract
BACKGROUND In patients with cirrhosis, progression to acute decompensation (AD) and acute-on-chronic liver failure (ACLF) has been associated with poor prognosis. Differential leucocyte ratios might predict mortality in systemic inflammatory conditions. AIM To evaluate differential leucocyte ratios as prognostic biomarkers in patients with cirrhosis. METHODS Patients with AD and ACLF were recruited from four centres in three countries. Peripheral blood differential leucocytes were measured (three centres using flow cytometry) on hospital admission and at 48 hours. Ratios were correlated to model for end-stage liver disease (MELD), chronic liver failure-sequential organ failure (CLIF-SOFA), suspected/culture-positive bacterial infection and survival. RESULTS Nine hundred twenty-six patients (562 (61%) male, median age 55 (25-94) years) were studied. Overall, 350 (37%) did not survive to hospital discharge. Neutrophil-lymphocyte ratio (NLR) and monocyte-lymphocyte ratio (MLR) were elevated in patients with AD and ACLF who died during their hospital stay. On multivariate analysis NLR retained statistical significance independently of CLIF-SOFA or MELD. NLR >30 was associated with an 80% 90-day mortality in patients with ACLF but not AD. On sensitivity analysis for subgroups (alcohol-related liver disease and suspected sepsis), NLR and MLR retained statistically robust accuracy for the prediction of mortality. Significant predictive accuracy was only observed in centres using flow cytometry. CONCLUSION Leucocyte ratios are simple and robust biomarkers of outcome in ACLF, which are comparable to CLIF-SOFA score but dependent on leucocyte quantification method. NLR and MLR may be used as screening tools for mortality prediction in patients with acutely deteriorating cirrhosis.

INTERNATIONAL JOURNAL OF ENVIRONMENTAL RESEARCH AND PUBLIC HEALTH 2020; 17:ijerph17051727. [PMID: 32155772 PMCID: PMC7084714 DOI: 10.3390/ijerph17051727] [Citation(s) in RCA: 33] [Impact Index Per Article: 8.3] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 02/04/2020] [Revised: 03/01/2020] [Accepted: 03/04/2020] [Indexed: 12/17/2022]
Abstract
Background and aim: The aim of this study was to assess the diagnostic performance of new morphology-related indices and Child–Turcotte–Pugh (CTP) and Model for End-Stage Liver Disease (MELD) scores during hospitalization in predicting the onset of bacterial infection in patients with liver cirrhosis. Material and methods: A total of 171 patients (56.9% males; median age 59 years; total number of hospitalizations 209) with liver cirrhosis were included in this observational study. The diagnosis of cirrhosis was made on the basis of clinical, biochemical, ultrasonic, histological, and endoscopic findings. The neutrophil-to-lymphocyte ratio (NLR), lymphocyte-to-monocyte ratio (LMR), modified aspartate aminotransferase-to-platelet ratio index (APRI), aspartate aminotransferase-to-alanine aminotransferase ratio (AAR), Fibrosis-4 index (FIB-4), platelet-to-lymphocyte ratio (PLR), neutrophil-to-monocyte ratio (NMR), and CTP and MELD scores were calculated for the cases of patients with cirrhosis. Results: Bacterial infection was diagnosed in 60 of the 209 (28.7%) hospitalizations of patients with cirrhosis. The most common infections were urinary tract infection (UTI), followed by pneumonia and sepsis. The more severe the liver failure, the greater the bacterial infection prevalence and mortality. Patients with decompensated liver cirrhosis were infected more often than subjects with compensated cirrhosis (50.0% vs. 12.9%, p = 0.003). The calculated MELD score, CTP, NLR, LMR, AAR, monocyte count, and C-reactive protein (CRP) concentration were also related to the bacterial infection prevalence, and mortality areas under the curve (AUC) were 0.629, 0.687, 0.606, 0.715, 0.610, 0.648, and 0.685, respectively. The combined model with two variables (LMR and CTP) had the best AUC of 0.757. The most common bacteria isolated from patients with UTI were Escherichia coli, Enterococcus faecalis, and Klebsiella pneumonia. Gram-negative bacteria were also responsible for spontaneous bacterial peritonitis (SBP), and together with gram-positive streptococci and staphylococci, these microorganisms were isolated from blood cultures of patients with sepsis. Significant differences were found between CTP classification, MELD score, NLR, LMR, AAR, CRP, and PLR in patients with cirrhosis with, or without, bacterial infection. Conclusions: Bacterial infection prevalence is relatively high in patients with liver cirrhosis. Although all analyzed scores, including the LMR, NLR, aspartate aminotransferase (AST)/alanine aminotransferase (ALT), CRP, CTP, and MELD, allowed the prediction of bacterial occurrence, the LMR had the highest clinical utility, according to the area under the curve (AUC) and odds ratio (OR).

Abstract
STUDY DESIGN This was a retrospective observational study. OBJECTIVE To assess the diagnostic value of procalcitonin (PCT) and neutrophil lymphocyte ratio (NLR) for predicting surgical site infection (SSI) in patients undergoing spinal instrumentation surgery, we analyzed a large consecutive cohort of patients who had undergone spinal instrumentation surgery. SUMMARY OF BACKGROUND DATA Although PCT and NLR are commonly used as markers for bacterial infection, the diagnostic value of these factors for predicting SSI in the context of spinal instrumentation surgery has not been extensively investigated. METHODS We retrospectively investigated 242 patients who underwent spinal instrumentation surgery and evaluated the significance of various postoperative measures for predicting SSI, including PCT and NLR. We then determined the diagnostic cut-off values for these markers in the prediction of SSI using receiver operating characteristic curve analysis. RESULTS Among the 242 patients analyzed, 10 were diagnosed with infection. Even though univariate analysis showed that neutrophil percentage and NLR at 6 to 7 days postoperatively were significant predictors for SSI, PCT at 6 to 7 days postoperatively did not differ significantly between the SSI and non-SSI groups. The cut-off value used for neutrophil percentage at 6 to 7 days postoperatively was more than 69.0% [sensitivity, 80.0%; specificity, 70.0%; area under the curve, 0.737]. The cut-off value used for NLR at 6 to 7 days postoperatively was 3.87 (sensitivity, 70.0%; specificity, 73.2%; area under the curve, 0.688). CONCLUSION Neutrophil percentage and NLR at 6 to 7 days postoperatively were more useful markers than PCT at 6 to 7 days postoperatively for early prediction of SSI in patients who had undergone spinal instrumentation surgery. Therefore, routine use of PCT as a predictor of postoperative infection is not supported by the results of this study. LEVEL OF EVIDENCE 4.

Abstract
Neutrophil to lymphocyte ratio (NLR) is widely used to assess inflammatory diseases. We performed a systematic review to explore the prognostic role of NLR for the assessment of liver fibrosis and cirrhosis. Areas covered: We searched the PubMed and EMBASE databases for the eligible papers which explored the association between NLR and liver fibrosis/cirrhosis or investigated the prognostic value of NLR in cirrhotic patients. Expert commentary: In accordance with assessment of liver fibrosis stage, we classified papers into four subgroups by etiology. For the patients with nonalcoholic fatty liver disease (NAFLD) there was a significant association between NLR and fibrosis stage and nonalcoholic fatty liver disease activity score (NAS), while NLR had a negative correlation with fibrosis stage for the patients with chronic hepatitis B (CHB). As for the patients with and chronic hepatitis C (CHC), NLR might not be significantly associated with fibrosis stage.
