Abstract
Background The neutrophil-to-lymphocyte ratio (NLR) is a commonly used biomarker for acute inflammation that often rises during sepsis, making it a valuable diagnostic indicator for clinical practice. However, no consensus has been reached on the prognostic value of NLR for predicting the prognosis and mortality risk in adult sepsis patients. In light of this controversy, we conducted a meta-analysis to clarify the prognostic significance of NLR in adult sepsis patients. The meta-analysis was registered in the PROSPERO database (registration number CRD42023433143). Methods We performed a comprehensive literature search in PubMed, Cochrane Library, Ovid, and Springer databases, using retrieval terms "sepsis" or "septic shock" and "prognosis" or "mortality" for studies published between January 1, 2000, and May 31, 2023. Children and neonates with sepsis were excluded from our research. Two independent researchers conducted the literature search and data extraction. Consensus was reached when discrepancies occurred, and in case of persistent discrepancies, the final decision was made by the research supervisor. The hazard ratio (HR) and its corresponding 95% confidence interval (95% CI) were extracted from each study included in the analysis. A random-effects model was used to synthesize all HRs and their 95% CIs. Sensitivity analysis was performed to investigate heterogeneity. Sensitivity analysis was conducted to identify studies that had a significant impact on the overall results of the meta-analysis. Subgroup analysis and meta-regression were performed to explore sources of heterogeneity. Egger's test was also used to investigate publication bias in this meta-analysis. Results After a comprehensive literature search and screening, we included 12 studies comprising 10,811 patients for the meta-analysis. The pooled results indicated that patients with a higher NLR level were associated with a poor prognosis (Random-effects model, HR: 1.6273, 95% CI: 1.3951-1.8981). Heterogeneity testing showed significant heterogeneity (I2 = 87.2%, 95% CI: 79.5-92, p<0.0001). Sensitivity analysis was performed to investigate the sources of heterogeneity, which revealed that the omission of one highly sensitive study significantly reduced the I2 value. After removing this study, a strong association was found between a higher NLR level and poor prognosis and risk of death in adult sepsis patients (Random-effects model, HR: 1.6884, 95% CI: 1.4338-1.9882). Both subgroup analysis and meta-regression indicated that the study design and testing time of NLR were sources of heterogeneity. Egger's test showed no obvious publication bias in this meta-analysis. Conclusion NLR is a reliable and valuable biomarker for predicting prognosis and the risk of death in adult sepsis patients.

Neutrophil-to-lymphocyte ratio as a predictor of postoperative complications and readmissions after appendectomy in children. Updates Surg 2023; 75:2273-2278. [PMID: 37659982 DOI: 10.1007/s13304-023-01639-9] [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: 11/02/2022] [Accepted: 08/28/2023] [Indexed: 09/04/2023]
Abstract
To analyze the role of neutrophil-to-lymphocyte ratio (NLR) in predicting the development of postoperative complications and readmission after appendectomy in children. A retrospective single-centered case-control study was conducted on children who underwent appendectomy between 2017 and 2020. Demographics, time since symptoms onset, laboratory tests at admission, postoperative complications, and readmissions in the first 30 days after surgery were recorded. Sensitivity and specificity analysis of the parameters evaluated were determined by the area under the curve (AUC) represented on the receiver operating characteristic (ROC) curves. A total of 1,214 patients (765 males; 449 females) were included, with a median age at diagnosis of 10.4 years. The median time from symptom onset was 24 h. During the first 30 days after surgery, 149 postoperative complications were reported (12.3%). NLR at admission presented the highest AUC (0.753), with a cut-off point of 10.5 for maximum sensitivity (68.7%) and specificity (86.1%). Readmissions were reported in 45 cases (3.7%). NLR at admission presented an AUC of 0.794 significantly higher than neutrophils (0.696), leukocytes (0.654), and time since symptom onset (0.622), making these differences statistically significant (p < 0.001). The cut-off point of NLR > 12.4 was estimated, with a maximum sensitivity and specificity of 71.0% and 82.3% for predicting readmission. NLR is an independent predictor of postoperative complications and readmission in children with acute appendicitis. While its application in routine clinical practice has yet to be established, the NLR may provide clinicians with a tool for identifying high-risk surgical patients.

J Clin Med 2023; 12:6946. [PMID: 37959411 PMCID: PMC10648653 DOI: 10.3390/jcm12216946] [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: 10/07/2023] [Revised: 10/31/2023] [Accepted: 11/03/2023] [Indexed: 11/15/2023] Open
Abstract
The prediction of severity in acute calculous cholecystitis (AC) is important in therapeutic management to ensure an early recovery and prevent adverse postoperative events. We analyzed the value of the neutrophil-to-lymphocyte ratio (NLR), platelet-to-lymphocyte ratio (PLR), and systemic inflammatory index (SII) to predict advanced inflammation, the risk for conversion, and postoperative complications in AC. Advanced AC was considered the cases with empyema, gangrene, perforation of the gallbladder, abscesses, or difficulties in achieving the critical view of safety. A 3-year retrospective was performed on 235 patients admitted in emergency care for AC. The NLR was superior to the PLR and SII in predicting advanced inflammation and risk for conversion. The best predictive value was found to be at an NLR "cut-off" value of >4.19, with a sensitivity of 85.5% and a specificity of 66.9% (AUC = 0.824). The NLR, SII, and TG 13/18 correlate well with postoperative complications of Clavien-Dindo grade IV (p < 0.001 for all variables) and sepsis. For predicting early postoperative sepsis, TG 13/18 grading >2 and NLR > 8.54 show the best predicting power (AUC = 0.931; AUC = 0.888, respectively), although not significantly higher than that of the PLR and SII. The NLR is a useful biomarker in assessing the severity of inflammation in AC. The SII and PLR may be useful in the prediction of systemic inflammatory response.

Ann Surg Treat Res 2023; 104:332-338. [PMID: 37337601 PMCID: PMC10277177 DOI: 10.4174/astr.2023.104.6.332] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/19/2023] [Revised: 04/06/2023] [Accepted: 05/15/2023] [Indexed: 06/21/2023] Open
Abstract
Purpose The aim of this study is to examine the effectiveness of the neutrophil-lymphocyte ratio (NLR) and CRP/albumin ratio (CAR) in evaluating disease severity and predicting clinical outcomes in patients diagnosed with acute cholecystitis (AC). Methods A total of 186 patients with AC were evaluated retrospectively. NLR, CAR, Mannheim Peritonitis Index (MPI), and P-POSSUM (Portsmouth Physiological and Operative Severity Score for the enUmeration of Mortality and Morbidity) scores were compared with AC severity grade. Results The rates of the grade 1 patients (group 1) and the grade 2-3 patients (group 2) were 57.5% (n = 107) and 42.5% (n = 79) according to the disease severity according to Tokyo Guidelines criteria (TG) 18/TG13, respectively. The morbidity rates determined in groups 1 and 2 were 26.7% (n = 28) and 51.9% (n = 41), respectively. No mortality was found in group 1, whereas the mortality rate in group 2 was 6.3% (n = 5). According to multivariate analysis, CAR (odds ratio [OR], 1.234; P < 0.001) and MPI (OR, 1.175; P = 0.001) were found to be associated with moderate-severe disease while CAR (OR, 1.109; P = 0.035) and P-POSSUM morbidity (OR, 1.063; P = 0.007) variables were found to be associated with the presence of morbidity. Conclusion We have demonstrated that CAR can be used in predicting severity of AC and that CAR is an alternative simple parameter of P-POSSUM morbidity score in prediction of morbidity in these cases. In addition to other assessment methods, these scores can provide valuable and complementary information in assessment of disease severity and prognosis in AC.

Neutrophil-lymphocyte Ratio Predicts Clinical Response to Percutaneous Transhepatic Biliary Drainage in Acute Cholangitis. J Clin Exp Hepatol 2023; 13:390-396. [PMID: 37250890 PMCID: PMC10213841 DOI: 10.1016/j.jceh.2023.01.002] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 09/12/2022] [Accepted: 01/02/2023] [Indexed: 05/31/2023] Open
Abstract
Background Predicting response to biliary drainage is critical to stratify patients with acute cholangitis. Total leucocyte count (TLC) is one of the criteria for predicting the severity of cholangitis and is routinely performed. We aim to investigate the performance of neutrophil-lymphocyte ratio (NLR) in predicting clinical response to percutaneous transhepatic biliary drainage (PTBD) in acute cholangitis. Patients and methods This retrospective study comprised consecutive patients with acute cholangitis who underwent PTBD and had serial (baseline, day 1, and day 3) TLC and NLR measurements. Technical success, complications of PTBD, and clinical response to PTBD (based on multiple outcomes) were recorded. Univariate and multivariate analysis was performed to identify factors significantly associated with clinical response to PTBD. The sensitivity, specificity, and area under the curve of serial TLC and NLR for predicting clinical response to PTBD were calculated. Results Forty-five patients (mean age 51.5 years, range 22-84) met the inclusion criteria. PTBD was technically successful in all the patients. Eleven (24.4%) minor complications were recorded. Clinical response to PTBD was recorded in 22 (48.9%) patients. At univariate analysis, the clinical response to PTBD was significantly associated with baseline TLC (P = 0.035), baseline NLR (P = 0.028), and NLR at day 1 (P=0.011). There was no association with age, the presence of comorbidities, prior endoscopic retrograde cholangiopancreatography, admission to PTBD interval, diagnosis (benign vs. malignant), severity of cholangitis, organ failure at baseline, and blood culture positivity. At multivariate analysis, NLR-1 independently predicted the clinical response. Area under the curve of NLR at day 1 for predicting clinical response was 0.901. NLR-1 cut-off value of 3.95 was associated with sensitivity and specificity of 87% and 78%, respectively. Conclusion TLC and NLR are simple tests that can predict clinical response to PTBD in acute cholangitis. NLR-1 cut-off value of 3.95 can be used in clinical practice to predict response.

Abstract
Background In this study, we evaluated neutrophil-to-lymphocyte ratio (NLR) values and abdominal computed tomography (CT) scans in preoperative patients of acute cholecystitis (AC) and their significance in differentiating between severe and non-severe conditions. This study will help further in-depth investigation on both of these diagnostic modalities and timely assess severe AC to avoid the worst prognosis. Methodology This single-center, cross-sectional study was conducted at Government Villupuram Medical College from July 2021 to January 2022. We enrolled patients aged >18 years diagnosed with AC. The demographic variables and clinical features of the enrolled patients were collected. All enrolled patients were divided into two categories (severe or non-severe AC) based on the pathological and clinical findings. The data were collected and entered in SPSS Statistics version 26 (IBM Corp., Armonk, NY, USA). The variation between the severe and non-severe AC groups was compared using Student's t-test to analyze continuous variables. The chi-square test was used to evaluate the association between the categorical variables. A p-value of <0.05 was considered significant. Results Among patients with severe AC, 29 (72.5%) were female, 29 (72.5%) were aged >50 years, 34 (85%) were alcoholics, and 26 (65%) were smokers. In patients with severe AC, the mean for NLR was 18.6500 ± 2.32655. On CT scans, 29 (72.5%) patients showed gallbladder distension, 31 (77.5%) showed increased pericholecystic fat stranding, and 18 (45%) showed pericholecystic fluid collection. CT scan findings and NLR values were significantly associated. Conclusions Gallbladder distension, increased pericholecystic fat stranding, and pericholecystic fluid collection on abdominal CT scan along with raised NLR are significant findings associated with assessing the severity of AC. Therefore, both testing modalities (CT scan and NLR) should be utilized together in hospitals to achieve better outcomes for AC and avoid complications.

Abstract
Background Cancellations of surgeries for elective cases and late admissions of symptomatic cases during the pandemic period might have increased the number of cases of acute cholecystitis and its complications. Purpose To compare the severity of acute cholecystitis and complication rates during the pandemic and pre-pandemic periods. Material and Methods We evaluated the computed tomography (CT) findings observed for the diagnosis of complications for both acute simple and acute complicated cholecystitis during both the pandemic and pre-pandemic periods. Patients admitted to the hospital between March 2020 and December 2020 made up the study group and the corresponding appropriate patients from one year earlier were studied as the control group. In addition to the CT findings, clinical and laboratory findings, co-morbidities such as diabetes, as well as the admission time to hospital from the onset of the initial symptoms to hospital admission were also evaluated. Results A total of 88 patients were evaluated (54 in the study group, 34 in the control group; mean age = 64.3 ± 16.3 years). The male-to-female ratio was 51/37. The number of patients diagnosed with complicated cholecystitis were significantly higher in the study group ( P = 0.03). Murphy finding and diabetes status were similar between the two groups ( P = 0.086 and P = 0.308, respectively). Admission time to the hospital was significantly different for study and control groups in simple cholecystitis patients ( P = 0.045); with no significant difference in cases of complicated cholecystitis ( P = 0.499). Conclusion Our study reveals the course of acute cholecystitis during the pandemic period was much more serious with higher complications.

Abstract
Background: Acute cholecystitis (AC) is one of the most common gastrointestinal diseases that require hospitalization and surgical treatment. The treatment of the disease depends upon the severity of the disease and the patients’ medical status. Objective: In this study, we aimed to investigate if there is an association between the serum C-reactive protein (CRP) value and treatment response and the duration and length of hospital stay in AC patients who are treated conservatively. Methodology: The medical records of all patients with the diagnosis of AC who were treated with conservative management were included in the study. The demographic and laboratory data including CRP level at first admission to hospital, length of hospital stay, and complications during the conservative treatment were obtained from the patients’ records. Patients were divided into two groups according to the treatment response and length of hospital stay. Group 1 patients were defined as patients who responded to the medical treatment in less than three days, and Group 2 patients were defined as patients who did not respond to the medical treatment in three days and stayed at the hospital for more than three days. Results: We identified 101 patients with AC treated medically. Mean age (51.3 ± 16.3, 59.5 ± 15.7; p = 0.013), total leukocyte count (11.8 ± 4.4, 8.2 ± 2.8; p = 0.0005), and CRP value (19.3 ± 13.9, 9.6 ± 5.2; p = 0.0003) were higher in Group 2 compared to Group 1. Correlation analyses demonstrated a significant positive association between the length of hospital stay, total leukocyte count (r = 0.35; p = 0.0002), and CRP value (r = 0.59; p = 0.0004). Conclusion: We found that CRP level is associated with treatment duration and hospital stay in AC patients. However, large-scale, prospective further studies are needed to confirm our results and to determine whether CRP levels can be used to discriminate which patient would benefit from medical treatment.

[PMID: 35208579 PMCID: PMC8878991 DOI: 10.3390/medicina58020255] [Citation(s) in RCA: 5] [Impact Index Per Article: 2.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/20/2022] [Revised: 02/04/2022] [Accepted: 02/07/2022] [Indexed: 12/24/2022] Open
Abstract
Background and objectives: Acute cholangitis can be life-threatening if not recognized early. We investigated the predictive value of the neutrophil–lymphocyte ratio (NLR) in acute cholangitis. Materials and Methods: We retrospectively evaluated 206 patients with acute cholangitis who underwent biliary drainage. The severity of acute cholangitis was graded according to the Tokyo 2018 guideline. Patients were dichotomized according to the acute cholangitis severity (mild/moderate vs. severe), the presence of shock requiring a vasopressor/inotrope, and blood culture positivity. The baseline NLR, white blood cell (WBC) count, and C-reactive protein (CRP) levels were compared between groups. Results: The severity of acute cholangitis was graded as mild, moderate, or severe in 71 (34.5%), 107 (51.9%), and 28 (13.6%) patients, respectively. Ten patients (4.8%) developed shock. Positive blood culture (n = 50) was observed more frequently in severe acute cholangitis (67.9% vs. 17.4%, p < 0.001). The NLR was significantly higher in patients with severe cholangitis, shock, and positive blood culture. The area under the curve (AUC) for the NLR, WBC, and CRP for severe acute cholangitis was 0.87, 0.73, and 0.74, respectively. The AUC for the NLR, WBC, and CRP for shock was 0.81, 0.64, and 0.67, respectively. The AUC for the NLR, WBC, and CRP for positive blood culture was 0.76, 0.64, and 0.61, respectively; the NLR had greater power to predict disease severity, shock, and positive blood culture. The optimal cut-off value of the baseline NLR for the prediction of severe acute cholangitis, shock, and positive blood culture was 15.24 (sensitivity, 85%; specificity, 79%), 15.54 (sensitivity, 80%; specificity, 73%), and 12.35 (sensitivity, 72%; specificity, 70%), respectively. The sequential NLR values from admission to 2 days after admission were significantly higher in patients with severe cholangitis and shock. Conclusions: An elevated NLR correlates with severe acute cholangitis, shock, and positive blood culture. Serial NLR can track the clinical course of acute cholangitis.

Abstract
PURPOSE To reveal the clinical significance of preoperative haematological inflammatory markers in the diagnosis of abdominal wall hernias with strangulation. METHODS The data of 200 patients who underwent surgery for incarcerated hernia were retrospectively analysed. The patients were grouped into three groups; Group 1; only surgical reduction and hernia repair, Group 2; small bowel resection and Group 3; omentum resection. Age, gender, hernia type, the presence of radiological bowel obstruction and preoperative complete blood count data were obtained. Neutrophil-leukocyte ratio (NLR), lymphocyte-monocyte ratio (LMR), platelet-lymphocyte ratio (PLR), haematological inflammatory index (HII) and systemic immune-inflammation index (SII) values were calculated. RESULTS The study was consisted of; Group 1: 119 patients (59.5%), Group 2: 46 patients (23%) and Group 3: 35 patients (17.5%). Advanced age (p = 0.001), female gender (p = 0.036), incisional hernias (p = < 0.001) and the presence of bowel obstruction (p = < 0.001) were found to be statistically significant in terms of strangulation. NLR, PLR and SII values were significantly higher in Group 2 compared to Group 1, and PLR values were significantly higher in Group 2 compared with Group 3 (p < 0.05). CONCLUSION The preoperative elevated NLR, PLR and SII values may indicate strangulation and possible intestinal resection, in incarcerated abdominal wall hernias.

Abstract
PURPOSE The aim of this review was to examine whether neutrophil-to-lymphocyte ratio (NLR) can predict the presence of cholecystitis and distinguish between simple and severe cholecystitis. METHODS A systematic literature search was performed. Risk of bias was assessed using the Newcastle-Ottawa Scale. Random effects model was used to calculate mean difference (MD) in two situations: (a) no cholecystitis versus cholecystitis and (b) simple versus severe cholecystitis. Receiver operating characteristic (ROC) curve analysis was performed to determine cut-off values of NLR for the above situations. RESULTS Ten retrospective studies comprising of 2827 patients were included. Three hundred twenty-seven had no cholecystitis, 2100 had simple cholecystitis and the remaining 400 had severe cholecystitis. NLR was significantly higher in acute cholecystitis compared to "no cholecystitis" (MD = 8.05 (95% CI 7.71-8.38), p < 0.01) and in severe cholecystitis when compared with simple cholecystitis (MD = 3.14 (95% CI 1.26-5.02), p < 0.01). For patients with cholecystitis compared to those without cholecystitis, an NLR cut-off value of 2.98 was identified (AUC = 0.90). Logistic regression analysis confirmed an NLR > 2.9 was an independent predictor of cholecystitis (OR 36.0, p = 0.006). In simple versus severe cholecystitis, an NLR cut-off value of 8.5 was identified (AUC = 0.73). Binary logistic regression analysis suggested an NLR > 8.5 was not an independent predictor of severe cholecystitis (OR 6.5 p = 0.090). CONCLUSION NLR is significantly higher in patients with cholecystitis of any severity compared to patients without cholecystitis. Moreover, NLR can predict acute cholecystitis. However, NLR cannot predict the severity of disease due to inadequately powered studies. Future research is required.

Abstract
Abdominal pain is the most common chief complaint in the Emergency Department. Abdominal pain is caused by a variety of gastrointestinal and nongastrointestinal disorders. Some frequently missed conditions include biliary pathology, appendicitis, diverticulitis, and urogenital pathology. The Emergency Medicine clinician must consider all aspects of the patient's presentation including history, physical examination, laboratory testing, and imaging. If no diagnosis is identified, close reassessment of pain, vital signs, and physical examination are necessary to ensure safe discharge. Strict verbal and written return precautions should be provided to the patient.

Abstract
BACKGROUND White blood cell levels (WBC) is the only biologic determinant criterion of the severity assessment of acute cholecystitis (AC) in the revised Tokyo Guidelines 2018 (TG18). The aims of this study were to evaluate the discriminative powers of common inflammatory markers (neutrophil-to-lymphocyte ratio (NLR), and C-reactive protein (CRP)) compared with WBC for the severity of AC, and the risk for conversion to open surgery and to determine their diagnostic cutoff levels. METHODS This was a prospective cohort study. Over 3 years, 556 patients underwent laparoscopic cholecystectomy for AC. Patients were classified into two groups: 139 cases of advanced acute cholecystitis (AAC) (gangrenous cholecystitis, pericholecystic abscess, hepatic abscess, biliary peritonitis, emphysematous cholecystitis), and 417 cases of non-advanced acute cholecystitis (NAAC). Multiple logistic regression and receiver-operating characteristic curve analysis were employed to explore which variables (WBC, CRP, and neutrophil-to-lymphocyte ratio (NLR)) were statistically significant in predicting AAC and conversion to open surgery. RESULTS On multivariable logistic regression analysis, male gender (OR = 0.4; p = 0.05), diabetes mellitus (OR = 7.8; p = 0.005), 3-4 ASA score (OR = 5.34; p = 0.037), body temperature (OR = 2.65; p = 0.014), and CRP (OR = 1.01; p = 0.0001) were associated independently with AAC. The value of the area under the curve (AUC) of the CRP (0.75) was higher than that of WBC (0.67) and NLR (0.62) for diagnosing AAC. CRP was the only predictive factor of conversion in multivariate analysis (OR = 1.008 [1.003-1.013]. Comparing areas under the receiver operating characteristic curves, it was the CRP that had the highest discriminative power in terms of conversion. CONCLUSION CRP is the best inflammatory marker predictive of AAC and of conversion to open surgery. We think that our results would support a multicenter-international study to confirm the findings, and if supported, CRP should be considered as a severity criterion of acute cholecystitis in the next revised version of the Guidelines of Tokyo.

Abstract
BACKGROUND The aim of this study is to determine whether pentraxin 3 (PTX3) levels can be used in the diagnosis of appendicitis in children. METHODS Fifteen children under 18 years old, who gave blood samples for reasons other than inflammatory conditions, and 40 children who were proved to have appendicitis (non-perforated or perforated) between August 2017 and January 2018, were enrolled in the study. Patients were classified into subgroups: group 1 (healthy children without any sign of inflammation, n = 15), group 2 (non-perforated appendicitis, n = 25), and group 3 (perforated appendicitis, n = 15). RESULTS The median PTX3 value was 1.01 ng/mL (minimum value: 0.82, maximum: 1.28) in the control group. The median PTX3 values prior to surgery were 20.68 ng/mL (minimum: 1.02, maximum: 28.471) and 1.46 (minimum: 1.05, maximum: 23.421) ng/mL for non-perforated appendicitis and perforated appendicitis respectively. The PTX3 levels were significantly higher in groups 2 and 3 than in group 1 (P < 0.01). According to receiver operating characteristics analysis the cut-off value of PTX3 levels at admission for appendicitis was 1.30 ng/mL with a sensitivity of 75% and a specificity of 100% (area under the curve, 0.939; P = 0.000). CONCLUSIONS Pentraxin 3 levels were significantly higher in children with appendicitis than in healthy children. Children with high PTX3 levels complaining of right lower quadrant pain may support a diagnosis of appendicitis. Future studies should be conducted to evaluate changes in PTX3 levels by comparing children with appendicitis versus acute abdominal pain in larger populations to further determine the value of PTX3 in the diagnosis of appendicitis in children.

Abstract
Systemic inflammation is known to cause WBC abnormalities, specifically neutrophilia and lymphopenia. The neutrophil-to-lymphocyte ratio (NLR) is a simple and affordable biomarker that has been used in human clinical settings of sepsis but has not been investigated in veterinary species. We evaluated NLR in dogs with septic and nonseptic systemic inflammatory diseases and compared with a healthy dog population. An NLR ≥6 had an 84.39% sensitivity and 86.95% specificity to identify dogs with systemic inflammatory states; however, no ratio distinguished septic and nonseptic causes. The NLR was not associated with length of hospitalization, morbidity based on the acute patient physiologic laboratory evaluation scoring system, or mortality. The disassociation may be due to the retrospective nature of the study, including a restricted population size and acquisition of only a one-time blood sample. NLR is currently of limited use for diagnosis and prognosis in systemic inflammatory states in dogs, and larger, prospective studies are necessary to further evaluate NLR.

Abstract
BACKGROUND The predictive value of preoperative neutrophil-to-lymphocyte ratio (NLR) in patients with cholecystitis has not been established. The aim of this study was to investigate preoperative NLR in patients with cholecystitis and to identify a relevant NLR value that discriminates between simple and severe cholecystitis. METHODS This study included 136 patients who under went laparoscopic cholecystectomy due to cholecystitis. The Receiver Operating Characteristic (ROC) analysis was performed to identify the most useful NLR cut-off value in relation to the severity of cholecystitis. The patients were di vided into two groups according to the cut-off NLR value: high NLR group (≥4.18, n=23) and low NLR group (<4.18, n=113). Severe cholecystitis was defined as a state which includes inflammation, empyema, gangrene, perforation of gallbladder, adhesions or difficulty in dissecting Calot's triangle. RESULTS In the high NLR group, severe cholecystitis (p<0.0001) and higher C-reactive protein level (CRP) and white blood cells count (WBC) (p<0.0001) were significantly more frequent. There was no difference in homeostatic model assessment-insulin resistance index (HOMA-IR) between both groups before the operation (p<0.634). The incidence of severe cholecystitis was 16.9%. The NLR of 4.18 could predict severe cholecystitis with 78.3% sensitivity and 74.3% specificity. Spearman's correlation revealed significant association between the preoperative NLR and HOMA-IR on day 1, (r=0.254, p=0.030) and between preoperative NLR and CRP on day 1 (ρ=0.355; p<0.0001). CONCLUSIONS NLR ≥4.18 was significantly associated with severe cholecystitis. The preoperative NLR in patients under going cholecystectomy due to cholecystitis could be a useful surrogate marker of severe cholecystitis.

Abstract
BACKGROUND Although several investigators have reported that inflammation-based prognostic scores can predict disease severity in patients with various inflammatory diseases, whether or not these scores are associated with disease severity in patients with acute cholecystitis (AC) has not yet been fully clarified. PATIENTS AND METHODS Two hundred and sixty-two patients with AC were reviewed retrospectively. We evaluated the correlations between demographic or clinical variables, including the neutrophil-to-lymphocyte ratio (NLR), the Glasgow Prognostic Score (GPS), the modified Glasgow Prognostic Score (mGPS), and the C-reactive protein/albumin (CRP/Alb) ratio, as well as the disease severity grade on the basis of the revised Tokyo guidelines. Multivariate analyses were carried out to identify the clinical parameters associated with disease severity grade. RESULTS The NLR (P<0.0001), GPS (P<0.0001), mGPS (P<0.0001), and CRP/Alb ratio (P<0.0001) were all elevated according to the severity grade. Multivariate analyses showed that the NLR [odds ratio (OR)=3.41-4.77; P<0.005], GPS (OR=2.49; P=0.012), mGPS (OR=2.79; P=0.005), and the CRP/Alb ratio (OR=12.53; P<0.0001) were associated independently with grade II/III AC. The value of the area under the curve of the CRP/Alb ratio (continuous 0.759) or NLR (continuous 0.753) was higher than that of other inflammation-based prognostic scores for diagnosing ≥grade II AC, grade III AC, respectively. CONCLUSION Inflammation-based prognostic scores could predict the severity grade independently in patients with AC. These scores may play a complementary role in predicting disease severity in patients with AC in conjunction with the Tokyo guidelines severity grade.

Abstract
PURPOSE The neutrophil-to-lymphocyte ratio (NLR) is an effective predictor of mortality in patients with for various conditions. To date, there are no previous studies on NLR as a prognostic marker for pyogenic liver abscess (PLA), especially on admission to the emergency department (ED). METHODS From January 2013 to December 2015, 102 patients diagnosed with PLA in the ED were included. Clinico-radiological and laboratory results, including NLR, were evaluated as variables. NLR was calculated as absolute neutrophil count/absolute lymphocyte count. To evaluate the prognosis of PLA, data on hospital mortality, intensive care unit (ICU) admission, and development of septic shock were obtained. Multivariate logistic regression analyses and receiver-operating characteristic (ROC) curve analysis were performed. RESULTS Among 102 patients, 10 (9.8%) died, 14 (13.7%) were admitted to the ICU, and 15 (14.7%) developed septic shock during hospitalization. Multivariate logistic regression analysis revealed NLR as an independent factor in predicting death [odds ratio (OR), 1.4; p = 0.020], ICU admission (OR, 1.4; p = 0.021), and development of septic shock (OR, 1.6; p = 0.041). NLR showed an excellent predictive performance for death (areas under the ROC curves [AUC], 0.941; cut-off value, 19.7; p < 0.001), ICU admission (AUC, 0.946; cut-off value, 16.9; p < 0.001), and development of septic shock (AUC, 0.927; cut-off value, 16.9; p < 0.001). CONCLUSION NLR was positively associated with poor prognosis of PLA; elevated NLR could predictor of high risk of death, ICU admission, and development of septic shock. Emergency physicians should consider NLR for the prognosis of PLA and early aggressive treatment, especially in patients with NLR > 16.9.

Abstract
BACKGROUND In recent years, there has been an increasing trend towards day-case surgery for patients undergoing laparoscopic cholecystectomy (LC). We investigated the predictive value that pre-operative neutrophil-to-lymphocyte ratio (PNLR) had on surgical outcomes. METHODS A review of all patients who underwent LC during a 6-year period in a single institution was performed and PNLR recorded. A PNLR cutoff value of 3 was utilised. We compared operation time, length of stay (LOS), and conversion to open between those with PNLR less and greater than 3. RESULTS A total of 567 patients underwent elective LC. Those with PNLR>3 had associated prolonged operation time (p < 0.005), prolonged LOS (p < 0.005), and higher rates of conversion to open surgery (p < 0.005). CONCLUSIONS PNLR correlates with outcomes following LC. It is useful in delineating patients that have higher risk of conversion or prolonged length of hospital stay and is helpful in assessing suitability of day-case surgery.
