Abstract
Serum amyloid A (SAA) is a cardiovascular risk factor and may serve as a predictor of infarct-related artery (IRA) patency in patients with ST-segment elevation myocardial infarction (STEMI). We measured SAA levels in STEMI patients who underwent percutaneous coronary intervention (PCI) and investigated their association with IRA patency. According to the Thrombolysis in Myocardial Infarction (TIMI) flow grade, 363 STEMI patients undergoing PCI in our hospital were divided into an occlusion group (TIMI 0-2) and a patency group (TIMI 3). The SAA level before PCI was significantly higher in STEMI patients with IRA occluded than in those with patent ones. At a cutoff value of 36.9 mg/L, SAA had a sensitivity of 63.0% and a specificity of 90.6% (area under the ROC curve [AUC] = .833, 95% CI: .793-.873, P < .001). Multivariate logistic regression analysis showed that SAA was an independent predictor of IRA patency in STEMI patients before PCI (odds ratio [OR] = 1.041, 95% CI: 1.020-1.062, P < .001). SAA can be used as a potential predictor of IRA patency in STEMI patients before PCI.

Abstract
Background Mortality due to Covid-19 and severe community-acquired pneumonia (CAP) remains high, despite progress in critical care management. We compared the precision of CURB-65 score with monocyte-to-lymphocyte ratio (MLR), neutrophil-to-lymphocyte ratio (NLR), platelet-to-lymphocyte ratio (PLR) in prediction of mortality among patients with Covid-19 and CAP presenting to the emergency department. Methods We retrospectively analysed two cohorts of patients admitted to the emergency department of Canakkale University Hospital, namely (i) Covid-19 patients with severe acute respiratory symptoms presenting between 23 March 2020 and 31 October 2020, and (ii) all patients with CAP either from bacterial or viral infection within the 36 months preceding the Covid-19 pandemic. Mortality was defined as in-hospital death or death occurring within 30 days after discharge. Results The first study group consisted of 324 Covid-19 patients and the second group of 257 CAP patients. The non-survivor Covid-19 group had significantly higher MLR, NLR and PLR values. In univariate analysis, in Covid-19 patients, a 1-unit increase in NLR and PLR was associated with increased mortality, and in multivariate analysis for Covid-19 patients, age and NLR remained significant in the final step of the model. According to this model, we found that in the Covid-19 group an increase in 1-unit in NLR would result in an increase by 5% and 7% in the probability of mortality, respectively. According to pairwise analysis, NLR and PLR are as reliable as CURB-65 in predicting mortality in Covid-19. Conclusions Our study indicates that NLR and PLR may serve as reliable predictive factors as CURB-65 in Covid-19 pneumonia, which could easily be used to triage and manage severe patients in the emergency department.

Abstract
Objective To investigate the feasibility of multimodal regimen by paracetamol, gabapentin, ketamine, lidocaine, dexmedetomidine and sufentanil among cardiac surgery patients, and compare the analgesia efficacy with conventional sufentanil-based regimen. Design A single-center, prospective, randomized, controlled clinical trial. Setting One participating center, the cardiovascular center of the major integrated teaching hospital. Participants A total of 115 patients were assessed for eligibility: 108 patients were randomized, 7 cases were excluded. Interventions The control group (group T) received conventional anesthesia management. Interventions in the multimodal group (group M) were as follows in addition to the standard of care: gabapentin and acetaminophen 1 hour before surgery; ketamine for induction and to maintain anesthesia with lidocaine and dexmedetomide. Ketamine, lidocaine, and dexmedetomidine were added to routine sedatives postoperatively in group M. Measurements and Main Results The incidence of moderate-to-severe pain on coughing made no significant difference (68.5% vs 64.8%, P=0.683). Group M had significantly less sufentanil use (135.72µg vs 94.85µg, P=0.000) and lower rescue analgesia rate (31.5% vs 57.4%, P=0.007). There was no significant difference in the incidence of chronic pain, PONV, dizziness, inflammation index, mechanical ventilation time, length of stay, and complications between the two groups. Conclusion Our multimodal regimen in cardiac surgery is feasible, but was not superior to traditional sufentanil-based regimen in the aspects of analgesia effects; however, it did reduce perioperative opioid consumption along with rescue analgesia rate. Moreover, it showed the same length of stay and the incidences of postoperative complications.

Abstract
BACKGROUND Although the prognosis of patients with Takotsubo syndrome (TTS) is relatively favorable, serious complications may occur. This study aimed to investigate the relationship between blood parameters and the occurrence of in-hospital complications. METHODS Clinical charts of 51 patients with TTS were retrospectively evaluated, and data regarding blood parameters assessed during the first 24 hours of hospitalization were studied. RESULTS Levels of hemoglobin less than 13 g/dL in men and 12 g/dL in women (P < 0.01), levels of mean corpuscular hemoglobin concentration (MCHC) less than 33 g/dL (P = 0.01), and levels of red blood cell distribution width-coefficient of variation higher than 14.5% (P = 0.01) were significantly associated to the occurrence of major adverse cardiovascular events (MACE). Markers, such as, platelets to lymphocytes ratio, lymphocytes to monocytes ratio, neutrophils to lymphocytes ratio, and white blood cell count to mean platelet volume, were unable to differentiate patients with and without complications (P > 0.05). MCHC and estimated glomerular filtration rate were independent predictors of MACE. CONCLUSIONS Blood parameters may have a role in the stratification risk of patients with TTS. Patients showing low levels of MCHC and decreased estimated glomerular filtration rate were more likely to have in-hospital MACE. This should encourage physicians to closely monitor blood parameters in patients with TTS.

Abstract
A significant proportion of patients presenting with non-ST-segment elevation myocardial infarction (NSTEMI) have a totally occluded culprit artery (OCA). If these patients do not meet very high-risk criteria, they may be deprived of an immediate invasive strategy. Therefore, there is a need for markers that can predict OCA in patients with NSTEMI. A total of 357 consecutive patients with NSTEMI but without very high-risk criteria were included in this retrospective study. Two groups were formed: NSTEMI with OCA (n = 106) and NSTEMI with patent culprit artery (PCA) (n = 251). Complete blood count (CBC) and serum biochemical parameters obtained immediately at admission were compared between the groups. Receiver operating characteristic (ROC) analysis to predict the presence of OCA was performed for the parameters that were significantly different between the groups, and an area under the curve (AUC) > 0.7 was considered to suggest acceptable discrimination. Neutrophil count [8.13 (2.82-27.88) × 103/µL vs 5.59 (1.85-19.71) × 103/µL, P < .001] and aspartate aminotransferase (AST) level [45 (12-405) U/L vs 25 (5-143) U/L, P < .001] were significantly higher in patients with OCA. The AUC was 0.750 for neutrophil count and 0.731 for AST level. The sensitivity, specificity, positive predictive value, and negative predictive value (NPV) of elevated neutrophil and/or AST levels for the presence of OCA were 77.4%, 70.1%, 52.2%, and 88.0%, respectively. More strikingly, the specificity was 95.2% in the presence of both neutrophil and AST elevation. Elevated neutrophil and/or AST levels at admission were strongly associated with the presence of OCA in patients with NSTEMI.

Abstract
Exposure to both cadmium (Cd) and lead (Pb) can promote systemic inflammation. However, the effects of combined exposure to environmental levels of Cd and Pb on systemic immune inflammation have not been fully clarified. A total of 486 subjects (313 women and 173 men) living in either a control area or heavy metal-polluted area were included. Blood Cd and Pb and immune inflammation biomarkers were determined, including the eosinophil-lymphocyte ratio (ELR), neutrophil-lymphocyte ratio (NLR), platelet-lymphocyte ratio (PLR), lymphocyte-monocyte ratio (LMR), and systemic immune-inflammation index (SII); moreover, the associations between exposure markers and systemic inflammation markers were analysed. The exposure levels in the polluted area were significantly higher than those in the control area. The NLR, PLR, and SII of subjects in the polluted area were higher and the LMR was lower than in the control area. Blood Pb and Cd levels are associated with elevated or decreased immune inflammation biomarkers in subjects from the exposed and control areas. Furthermore, co-exposure to both Cd and Pb was divided into high, middle, and low exposure groups. The subjects in the high co-exposure group displayed higher levels of ELR, NLR, and SII compared with the middle and low co-exposure group, and LMR levels displayed the opposite trend. Our data demonstrate that Cd and Pb co-exposure is associated with systemic immune inflammation, and the immune inflammatory response is aggravated with an increased co-exposure to Cd and Pb.

Abstract
The aim of this study was to investigate the predictive value of the platelet-to-lymphocyte ratio (PLR) and the China Acute Myocardial Infarction registry-ST segment elevation myocardial infarction (CAMI-STEMI) score for major adverse cardiovascular events (MACE) in ST-segment elevation myocardial infarction (STEMI) patients undergoing percutaneous coronary intervention (PCI) within 6 months.We enrolled STEMI patients who received emergency PCI in the First Hospital of Lianyungang from January 2016 to December 2019. The clinical characteristics of the patients, the PLR, and the CAMI-STEMI score were recorded. The MACE included heart failure, nonfatal re-infarction, recurrent angina pain, re-hospitalization for cardiovascular-related illness, repeat PCI, coronary artery bypass grafting, and all-cause mortality. According to the incidence of MACE during the follow-up the patients were divided into the MACE group (96 cases, 24.8%) and the non-MACE group (291 cases, 75.2%).The PLR, 147.62 (121.13-205.20) in MACE group, was 111.19 (90.23-146.42) in the non-MACE group in comparison, the PLR was higher in MACE group than that in non-MACE group (P < .01). Multivariate regression analysis showed that PLR (odds ratio (OR) = 1.007, 95% confidence interval (CI) 1.002-1.012, P < .01) and CAMI-STEMI score (OR = 1.575, 95% CI: 1.311-1.892, P < .01) were independent predictors of MACE. Besides, I-BIL was also an independent predictor of MACE (OR = 1.007, 95% CI: 1.011-1.146, P = .021). Reciever-operating characteristic curve showed that the area under curve of PLR was 0.704 (95%CI 0.644-0.763, P < .001). The cutoff value was 112.6, the sensitivity and specificity were 84.4% and 51.9%, respectively.PLR and CAMI-STEMI scores were independent risk factors of MACE after PCI in STEMI patients.

Abstract
Background: This study intended to use two novel inflammatory indicators: lymphocyte to high-density lipoprotein cholesterol ratio (LHR) and platelet to lymphocyte ratio (PLR), to predict newly diagnosed metabolic syndrome (MetS) among subjects from rural Northeast China. Methods: Adult participants without MetS at baseline (n = 4,980, age = 52.65 ± 10.21 years; 51.9% men) were originated from the Northeast China Rural Cardiovascular Health Study (NCRCHS). LHR (Q1: ≤1.04; Q2: 1.04–1.35; Q3: 1.35–1.79; Q4: ≥1.79) and PLR (Q1: ≤78.50; Q2: 78.50–107.27; Q3: 107.27–140.00; Q4: ≥140.00) were divided in quartile. Results: After 4.66-year follow-up, 1,194 subjects were diagnosed MetS (cumulative incidence 24.0; 25.8% for female and 22.3% for male, P = 0.002). Newly diagnosed MetS had higher value of hemoglobin and platelet count compared to those without MetS. As for LHR, from Q1 to Q4, there were increasing value of waist circumference (WC), serum triglycerides (TG), rates of current smoking and drinking whereas decreasing value of HDL-C. However, for PLR, rates of current smoking and drinking significantly decreased from Q1 to Q4. Similarly, the value of WC and TG showed a decreasing trend. In a logistic regression analysis, after adjusted for possible confounders, LHR [OR (95% CI) Q2: 1.13 (0.86, 1.48); OR (95% CI) Q3: 1.23 (0.94, 1.61); OR (95% CI) Q4: 1.57(1.20, 2.06)] but not PLR was effective predictor of newly diagnosed MetS among rural Chinese. Conclusion: MetS had closed relationship with inflammation among subjects from rural China. As a novel marker of inflammation, LHR but not PLR might be an effective predictor of newly diagnosed MetS and should be widely used in the epidemiological study.

Abstract
BACKGROUND Platelet-to-lymphocyte ratio (PLR) is a haematological index which reflects increased level of inflammation and thrombosis. We aimed to summarize the potential prognostic role of PLR for the in-hospital and long-term outcomes in ST-segment elevation myocardial infarction (STEMI) patients treated with primary percutaneous coronary intervention (pPCI) in a meta-analysis. MATERIALS AND METHODS Relevant cohort studies were identified by search the PubMed, Cochrane's Library and Embase databases. A random-effect model was applied to pool the results. In-hospital and long-term outcomes were compared between patients with higher and lower preprocedural PLR. RESULTS Eleven cohorts with 12 619 patients were included. Pooled results showed that higher preprocedural PLR was independently associated with increased risk of in-hospital major adverse cardiovascular events (MACE, risk ratio [RR]: 1.76, 95% confidence interval [CI]: 1.39 to 2.22, P < .001; I2 = 49%), cardiac mortality (RR: 1.91, 95% CI: 1.18 to 3.09, P = .009; I2 = 0), all-cause mortality (RR: 2.14, 95% CI: 1.52 to 3.01, P < .001, I2 = 24%) and no reflow after pPCI (RR: 2.22, 95% CI: 1.70 to 2.90, P < .001, I2 = 59%). Moreover, higher preprocedural PLR was associated with increased risk of MACE (RR: 1.60, 95% CI: 1.25 to 2.03, I2 = 57%, P < .001) and all-cause mortality (RR: 2.36, 95% CI: 1.53 to 3.66, I2 = 78%, P < .001) during long-term follow-up of up to 82 months after discharge. CONCLUSIONS Higher PLR predicts poor in-hospital and long-term prognosis in STEMI patients after pPCI.

Abstract
Recent studies have reported a relationship between the platelet to lymphocyte ratio (PLR) and acute coronary syndromes. The aim of the present study was to investigate the association between PLR and stable coronary artery disease (CAD). A systematic search was conducted based on electronic databases (Cochrane, PubMed, Elsevier, Medline, and Embase). A total of 14 studies (n = 4,871) were included in the meta-analysis. Compared with the non-CAD group, PLR was significantly higher in CAD group (P = .002). After further classification according to the Gensini score, the cases with atherosclerosis demonstrated a higher PLR than those without atherosclerosis (P < .001). Platelet to lymphocyte ratio was higher in the severe atherosclerosis group compared with the mild atherosclerosis group (P < .001). Compared with the poor coronary collateral circulation (CCC) group, PLR was significantly lower in the good CCC group (P < .001). The PLR was significantly higher in patients with coronary slow flow (CSF) than those with normal coronary flow (P = .01). On the basis of current evidence, an elevated PLR was associated with stable CAD, and it might be useful for predicting CAD severe stenosis, collateral circulation, and CSF. Future studies are needed to clarify the relationship between PLR and stable CAD.

Abstract
OBJECTIVE To compare the complete blood counts, namely the plateletcrit (PCT) and Platelet-To-Lymphocyte Ratio (PLR) of healthy subjects and those with morbid obesity in the young population. METHODS We included 45 patients with morbid obesity (body mass index -BMI - greater than or equal to 45 kg/m2) and 45 healthy subjects (BMI less than or equal to 25 kg/m2) in our study. Blood samples were obtained from the participants following a 12-hour fasting period. Then we evaluated the levels of hemoglobin (Hb), hematocrit (HCT), red cell distribution width (RDW), mean platelet volume (MPV), white blood cell (WBC), PLR, platelet counts, and PCT in the complete blood count. RESULTS The morbid obesity group had significantly higher platelet counts and PCT values (p<0.001), and PLR values (p=0.033). The value of WBC was also higher in the obese group (p=0.001). MPV was lower in the obesity group but not statistically significant (p=0.815). No significant difference was found between hemoglobin and hematocrit values in these groups; but RDW valuewere higher and statistically significant in the obese group (p=0.001). CONCLUSION PLR or PCT may be more useful as a marker in determining an increased thrombotic state and inflammatory response in morbid obesity.

Abstract
We investigated associations between inflammatory marker levels and hepatitis C virus (HCV)-related compensated liver cirrhosis risk in patients with chronic hepatitis C (CHC) infection in China. We used a case-control design and data from the records of 110 Chinese patients with CHC and cirrhosis for the study; 458 CHC patients who did not have a diagnosis of cirrhosis were matched to the case group by age and sex characteristics. We also investigated fatty liver disease risk factors. The group of patients with CHC infection and cirrhosis had lower platelet-to-lymphocyte ratio (PLR) values (60.63 [44.09, 89.31]) compared with the control group patients (80.24 [57.85, 111.08]). The results indicated that the group of patients with cirrhosis had higher 4-factor fibrosis index and aspartate aminotransferase (AST)-to-platelet ratio index (APRI) values compared with the group of patients with CHC-only (1.66 [0.98, 2.60] vs 0.71 [0.45, 1.17], respectively; P < .001 and 2.12 [0.97, 4.25] vs 0.99 [0.51, 2.01], respectively; P < .001). Compared with the control group, the AST/alanine aminotransferase ratio (AAR) values in the group of patients with cirrhosis were significantly higher (P < .001). Logistic regression analysis that included model adjustment for demographic characteristics and other factors that could affect cirrhosis risk revealed that greater 1/PLR values were associated with an increased odds of having cirrhosis (adjusted odds ratio [AOR], 95% confidence interval [CI] 0.991 [0.985-0.996]); APRI and AAR values were also independent predictors of the presence of compensated cirrhosis. We found that compared with the patients with CHC-only, the triglyceride, cholesterol, and low-density lipoprotein cholesterol levels in the patients with both CHC and fatty liver disease were significantly higher. The multivariate analysis of the risk of fatty liver development in patients with CHC infection found that cholesterol level was a statistically significant risk factor (AOR [95% CI] 1.380 [1.089-1.750], P = .008). Increased 1/PLR, APRI, and AAR values were associated with increased risks for development of cirrhosis in this population of Chinese patients with CHC infection. Higher cholesterol levels increased the risk of development of fatty liver disease in patients with CHC.

Abstract
Objective: White blood cell (WBC) count to mean platelet volume (MPV) ratio (WMR) is associated with major adverse cardiovascular events in patients with non-ST elevation acute coronary syndrome (NSTEMI). We aimed to compare WMR between NSTEMI patients and matched-controls and to evaluate its predictive value on SYNTAX score. Methods: Total 175 patients with NSTEMI and 160 age and co-morbidity matched subjects were recruited in our study. WMR was compared between the patient and control groups. The patient group was further subdivided into 3 tertiles according to SYNTAX scores as follows: low SYNTAX score tertile (score ≤22, 141 patients); intermediate SYNTAX score tertile (score between 23 and 32, 20 patients); and, high SYNTAX score tertile (score ≥33, 14 patients). WMR was further assessed among the tertiles. Results: WMR was significantly greater in the patient group compared to the control group (p<0,001). WMR among low, intermediate and high score tertiles were calculated to be 890±26, 1090±042 and 1500±65, respectively (p <0,001). In receiver operating characteristics (ROC) analysis, WMR >960 predicted a SYNTAX score ≥23 with 80.6% sensitivity and 67.6% specificity (AUC: 0.756; 95% CI: 0.685 - 0.818; p <0.0001) and a WMR >1360 predicted a SYNTAX score ≥33 with 71.4% sensitivity and 93% specificity (AUC: 0.840; 95%CI: 0.777 - 0.892; p <0.0001). Conclusions: WMR value was significantly elevated in NSTEMI patients, compared to controls. Higher WMR was associated with greater SYNTAX score in patients with NSTEMI. WMR may be used to predict severity of the CAD and to implement risk stratification in patients with NSTEMI.

Abstract
BACKGROUND Platelet to lymphocyte ratio (PLR) has been demonstrated as a risk and prognostic marker in many of cardiovascular diseases. A relationship between PLR and severity of carotid stenosis has been shown. The aim of our study was to investigate the relationship between PLR and all cause mortality in patients with carotid arterial disease. METHODS This retrospective study included 146 patients who had been performed selective carotid angiography. Carotid stenosis were graded by the North American Symptomatic Carotid Endarterectomy Trial (NASCET) criteria. Platelet to lymphocyte ratio was calculated as the ratio of platelets to lymphocytes. The end point of the study was all-cause mortality. RESULTS During median follow-up of 16 months (0-65 months) 15 (10.3%) patients suffered all-cause mortality. 50 patients (34.2%) underwent carotid endarterectomy and 69 patients (47.3%) had non-carotid cardiac surgery. 38 patients (26.02%) had cerebrovascular events (stroke/transient ischemic attack) at admission. NASCET grades were not different between survivors and non-survivors. Non-survivors had significantly lower hemoglobin (Hb) levels (12.7 ± 1.6 g/dL vs. 13.7 ± 1.7 g/dL, p = 0.031) and they were older than survivors (74.2 ± 8.4 years vs. 68.6 ± 8.5 years, p = 0.029). Non-survivors had significantly higher PLR values compared with survivors (190.3 ± 85.6 and 126.8 ± 53.8, p = 0.017). In multivariate analysis, only PLR predicted all-cause mortality in patients with carotid artery stenosis. CONCLUSION In our study, higher PLR was associated with increased all-cause mortality.

Abstract
The platelet to lymphocyte ratio (PLR) is an integrated reflection of 2 opposite thrombotic/inflammatory pathways that are easily calculated from a complete blood count. The PLR initially served as a systemic inflammatory biomarker to predict the prognosis of neoplastic diseases. In recent years, the PLR has been used as a prognostic marker in cardiovascular (CV) conditions. In this review, we consider the evidence regarding the association of the PLR with CV disease (CVD) and its possible use as a prognostic marker of CVD. The role of PLR has been investigated in CV conditions in several studies. We assessed clinical trials using PubMed, EMBASE, and Web of Science (up to April 18, 2018) to evaluate the association between PLR and mortality/major adverse cardiac events in these conditions. Most of these studies reported significant relationships between a high PLR and diverse outcomes. In conclusion, we suggest that PLR is a cheap and easily available systemic inflammatory marker that can predict distinct outcomes in different types of CVD.

Abstract
BACKGROUND Recent studies have shown that complete blood count (CBC) parameters can effectively predict long-term mortality and re-infarction rates in acute coronary syndrome (ACS). However, the role of these parameters in predicting short term mortality has not been studied extensively. The main objective of this study was to determine whether CBC parameters can predict 30-days mortality and the incidence of major adverse cardiac event (MACE) in ACS patients. METHODOLOGY A total of 297 patients with ACS were recruited in this prospective study. The relationship of baseline white blood cell (WBC) to mean platelet volume ratio (WMR) with MACE and mortality was assessed during a 30-days follow up. The patients were divided into two groups: Group A [WMR<1000] and Group B [WMR>1000]. Multivariate COX regression was performed to calculate hazard ratios (HR). RESULTS WMR had the highest area under receiver operating characteristics curve and highest discriminative ability amongst all CBC parameters in predicting mortality. Patients in Group B had a higher mortality rate (p<0.001) than patients in Group A. WBC count (p=0.02), platelet count (p=0.04), WMR (p=0.008), platelet to lymphocyte ratio (p<0.001) and neutrophil to lymphocyte ratio (p=0.03) were significantly higher in the MACE-positive group as compared to MACE-negative. In multivariate cox regression analysis, WMR>1000 (HR=2.9, 95% confidence interval 1.3-6.5, p=0.01) was found to be strongest biochemical marker in predicting mortality. CONCLUSION WMR is an easily accessible and an inexpensive indicator, which may be used as a prognostic marker in patients with ACS.

Abstract
Background The platelet to lymphocyte ratio (PLR), an indirect inflammatory biomarker, has been recently demonstrated to be associated with severity of coronary artery disease. In the present study, we sought to investigate whether PLR is associated with vulnerable plaque characteristics of non-culprit lesions in patients with acute coronary syndrome (ACS). Methods The patients in our study were divided into two groups (high PLR group and low PLR group). A total of 119 non-culprit plaques from 71 patients with ACS were assessed by optical coherence tomography (OCT). Results The non-culprit plaques in high PLR group exhibited thinner fibrous cap thickness (FCT) (88.60 ± 44.70 vs. 119.28 ± 50.22 μm, P = 0.001), greater maximum lipid arc (271.73 ± 71.66 vs. 240.60 ± 76.69°, P = 0.027) and increased incidence of thin-cap fibroatheroma (TCFA) (34.0% vs. 15.9%, P = 0.022) compared with those in low PLR group. Meanwhile, PLR was negatively associated with FCT (r = −0.329, P < 0.001). Furthermore, multivariate regression analysis showed that PLR [OR: 1.023 (95% CI: 1.005–1.041), P = 0.012] and LDL-C [OR: 1.892 (95% CI: 1.106–3.239), P = 0.020] were significant predictors of TCFA. Conclusions High level of PLR may be associated with vulnerable plaque features of non-culprit lesions in patients with ACS. PLR, a cheap and easily available index, may surve as a useful inflammatory marker in reflecting plaque vulnerability.

Abstract
We investigated the relationship between platelet to lymphocyte ratio (PLR) and contrast-induced nephropathy (CIN) in patients with ST-segment elevation myocardial infarction (STEMI) undergoing primary percutaneous coronary intervention (pPCI). We enrolled 5719 patients in 3 tertiary hospitals from January 2005 to December 2010. The PLR was calculated as the ratio of platelet to lymphocyte counts on admission. Serum creatinine level was measured before and within 72 hours after contrast medium administration. To evaluate the relation between PLR and CIN, the 5719 patients were divided into a CIN group and a non-CIN group. Contrast-induced nephropathy occurred in 252 (4.4%) patients. Patients in the CIN group had significantly higher PLR than those in the non-CIN group (173.8 [62.3] and 116.2 [51.7], respectively; P < .001). In logistic regression analysis, PLR was an independent predictor of CIN (odds ratio: 1.432, 95% confidence interval: 1.205-1.816, P = .031), along with age, diabetes mellitus, creatinine, estimated glomerular filtration rate, and neutrophil to lymphocyte ratio. In conclusion, a higher PLR was an independent risk factor for the development of CIN in patients with STEMI undergoing pPCI.

Abstract
OBJECTIVES By now, there are few data of the reference intervals (RIs) of SII, PLR, NLR, LMR and MLR. We aimed to establish RIs of SII, PLR, NLR, LMR and MLR for healthy persons. METHODS A retrospective analysis on a cohort of ostensibly healthy, aged no <18 years old physical examinees who took health examination from January to December in 2013 was conducted to explore influences of age and gender on SII, PLR, NLR, LMR and MLR and to establish their RIs. And another cohort of 450 persons in our hospital from January to July in 2016 is included for validations of RIs. RESULTS NLR, LMR and MLR were significantly different between gender groups (P=.010; P<.001; P<.001, separately), while SII and PLR were not (P=.137; P=.267, separately). While SII was not changed much between age groups (P=.842), PLR, NLR, LMR and MLR were significantly different (all with P<.001). RIs of SII, PLR, NLR, LMR and MLR were: SII: [161,701]; PLR: 18-65 year-old: [61,179]/>65 year-old: [55,179]; NLR: 18-65 year-old male: [0.90,2.94]/18-65 year-old female: [0.85,3.06]/>65 year-old male: [0.95,3.57]/aged >65 year-old female: [0.83,3.30]; LMR: 18-65 year-old male: [2.50,7.50]/18-65 year-old female: [2.75,8.50]/>65 year-old male: [2.16,7.41]/>65 year-old female: [2.40,8.33]; MLR: 18-65 year-old male: [0.12,0.35]/18-65 year-old female: [0.10,0.32]/>65 year-old male: [0.12,0.41]/>65 year-old male: [0.11,0.33]. CONCLUSIONS RIs of SII, PLR, NLR, LMR and MLR of people in central China were established and validated. It will benefit experimental design of the related studies and lead to better standardizations of SII, PLR, NLR, LMR and MLR for their clinical applications.

Abstract
We aimed to investigate the relationship between platelet-to-lymphocyte ratio (PLR) and contrast-induced acute kidney injury (CI-AKI) in patients with ST-segment elevation myocardial infarction (STEMI) undergoing primary percutaneous coronary intervention (pPCI). A total of 2563 patients diagnosed with STEMI and underwent primary pPCI were retrospectively included in the study. Levels of PLR and creatinine were measured before and at 72 hours after pPCI. Patients were divided into 2 groups: non-CI-AKI group and CI-AKI group. Contrast-induced acute kidney injury occurred in 6.4% of the overall study population. Patients in the CI-AKI group had significantly higher PLR than those in the non-CI-AKI group (169.18 ± 81.01 vs 149.49 ± 74.54, P < .001). In logistic regression analysis, PLR was an independent predictor of CI-AKI (odds ratio [OR]: 1.774, 95% CI: 1.243-2.532, P = .002), along with age, use of angiotensin-converting enzyme inhibitor/angiotensin receptor blocker prior to the procedure, preprocedural creatinine level, amount of contrast material used during the procedure, and hypertension. Increased PLR levels are independently associated with a greater risk of CI-AKI in patients undergoing primary PCI for STEMI.

Abstract
We investigated the association between platelet-to-lymphocyte ratio (PLR) and clinical outcomes (including all-cause mortality, recurrent myocardial infarction, heart failure, serious cardiac arrhythmias and ischemic stroke) in patients with ST-segment elevation myocardial infarction (STEMI). Based on PLR quartiles, 5886 patients with STEMI were categorized into 4 groups: <98.8 (n = 1470), 98.8 to 125.9 (n = 1474), 126.0 to 163.3 (n = 1478), >163.3 (n = 1464), respectively. We used Cox proportional hazards models to examine the relation between PLR and clinical outcomes. Mean duration of follow-up was 81.6 months, and 948 patients (16.1%) died during follow-up. The lowest mortality occurred in the lowest PLR quartile group ( P = 0.006), with an adjusted hazard ratio of 1.18 (95% confidence interval [CI], 1.04-1.55), 1.31 (95% CI, 1.18-1.64), and 1.59 (95% CI, 1.33-1.94) in patients with PLR of 98.8 to 125.9, 126.0 to 163.3, >163.3, respectively. Higher levels of PLR were also associated with recurrent myocardial infarction ( Ptrend = .023), heart failure ( Ptrend = .018), and ischemic stroke ( Ptrend = .043). In conclusion, a higher PLR was associated with recurrent myocardial infarction, heart failure, ischemic stroke, and all-cause mortality in patients with STEMI.

Int J Infect Dis 2016; 45:72-7. [PMID: 26948479 DOI: 10.1016/j.ijid.2016.02.025] [Citation(s) in RCA: 44] [Impact Index Per Article: 5.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/12/2015] [Revised: 02/18/2016] [Accepted: 02/25/2016] [Indexed: 02/07/2023] Open
Abstract
OBJECTIVES The platelet-to-lymphocyte ratio (PLR) and neutrophil-to-lymphocyte ratio (NLR) have been studied widely in cancer diseases. However, their correlation with hepatitis C virus (HCV) infection is unknown. The aim of this study was to investigate the correlation of PLR and NLR with disease severity in patients with HCV-related liver disease and the virological response in chronic hepatitis C (CHC) patients. METHODS The clinical data of 120 HCV-infected patients and 40 healthy controls were analyzed. The clinical data of 24 CHC patients who had been followed up regularly were collected for the following time points: before treatment (week 0) and weeks 4, 48, and 72 during treatment. These data were also analyzed. All data were collected from the database of the hospital patient electronic medical record system. RESULTS The HCV-related cirrhosis group and HCV-related hepatocellular carcinoma group were found to have lower PLRs (61±31 and 51±23) than the healthy controls (115±23). The PLR of the HCV cleared group (154±85) was significantly higher than that of the HCV untreated group and HCV uncleared group (90±28 and 88±40, respectively). Receiver operating characteristics curve analysis for the PLR showed an area under the curve of 0.772 (95% confidence interval 0.674-0.869, p<0.000); for NLR, the area under the curve was 0.612 (95% confidence interval 0.495-0.730, p=0.063). Furthermore, an increasing PLR in CHC patients indicated a good virological response, and a stable PLR or a downward trend in PLR could predict no rapid virological response being achieved by week 4, and even no sustained virological response by week 72. CONCLUSIONS The PLR is closely related to disease severity in patients with HCV-related liver disease and to the virological response in CHC patients. Dynamic continuous monitoring of the PLR will contribute to disease surveillance, with an increasing tendency predicting a good virological response.

Abstract
Atherosclerosis plays an important role in saphenous vein graft disease (SVGD). Previous trials showed that inflammatory blood cells play a role in this process. The platelet to lymphocyte ratio (PLR) has been proposed as a novel predictor for cardiovascular risk and indicator of atherosclerosis. The aim of this study was to assess the relationship between SVGD and PLR. A total of 220 patients with SVG were enrolled (n = 87 with SVGD and n = 133 with patent SVG). A ≥ 50% stenosis within the SVG was defined as clinically significant. Median PLR (P < .001) and mean platelet volume (MPV; P = .043) were significantly higher in patients with SVGD. Also, PLR showed significantly positive correlation with age of SVG (P < .05). Median age of SVGs was also higher in the SVGD group (P = .025). In multivariate logistic regression analyses, the PLR and MPV were independent predictors of SVGD. Using a cutoff level of 106.3, the PLR predicted SVGD with a sensitivity of 87.4% and a specificity of 80.3%. To the best of our knowledge, this study showed, for the first time, that PLR was independently associated with SVGD. Both PLR and MPV might predict SVGD.

Abstract
BACKGROUND Platelet-to-lymphocyte ratio (PLR) is an emerging inflammatory indicator which is closely associated with adverse cardiovascular events. Therefore, we aimed to investigate the relationship between PLR and the severity of calcific aortic stenosis (AS). MATERIAL AND METHODS The study was designed as a retrospective study. A total of 86 consecutive patients with calcific AS were divided into two groups as mild-to-moderate AS and severe AS according to the transaortic mean pressure gradient. PLR levels were calculated from the complete blood count (CBC). RESULTS Platelet to lymphocyte ratio was significantly higher in severe and mild-to-moderate AS groups when compared to the control subjects (151±31.2, p<0.001, 138±28.8 vs. 126±26.5, p=0.008, respectively). In the subgroup analysis of AS patients, PLR was found to be higher in the severe AS group compared to mild-to-moderate group (p<0.001). A significant correlation was found between PLR and transaortic mean pressure gradient in patients with AS (r=0.421, p<0.001). CONCLUSIONS Our study results demonstrated that increased PLR correlates with the severity of calcific AS.

Abstract
Metabolic syndrome (MetS) as a cluster of several cardio-metabolic components is rapidly growing public-health problem worldwide and significantly associated with poor cardiovascular outcomes. Increased visceral adiposity activates the important pathways connecting low-grade chronic inflammation, oxidative stress and blood coagulation. Recently, platelet to lymphocyte ratio (PLR) has been evidenced as a novel indirect inflammatory marker. Therefore, for the first time, we aimed to investigate the association of PLR with both the presence and severity of MetS. In this cross-sectional study, a total of 1146 participants were enrolled (n = 539 with MetS and n = 607 without MetS). MetS was defined according to NCEP-ATP III criteria. MetS (+) group revealed significantly higher PLR and C-reactive protein (CRP) levels as compared to MetS (-) group (p < 0.05). There was a graded relationship between increasing number of MetS components and PLR (p < 0.05). Also, PLR was positively correlated with CRP level (r = 0.163, p < 0.001). In multivariate regression analysis, PLR [1.121 (1.113-1.135), p < 0.001], CRP [1.044 (1.029-1.060), p < 0.001], and age [1.030 (1.017-1.043), p < 0.001] were remained as independent predictors for the presence of MetS. In conclusion, our findings showed that increased PLR was significantly associated with both the presence and severity of MetS which was linked to systemic inflammation based on the correlation between PLR and CRP. As PLR is an easily available, simple and cheap indirect indicator of inflammation, it can be used in clinical practice as a predictor of MetS.

Abstract
The platelet to lymphocyte ratio (PLR) has recently emerged as a potential inflammatory biomarker. Hence, we assessed the relationship between PLR and the extent/severity of coronary artery disease (CAD) using the Gensini score in association with the inflammatory marker C-reactive protein (CRP) in patients with stable CAD. Angiographic data of 1646 patients were analyzed in this cross-sectional study. Patients were categorized according to Gensini scores as no CAD (control), mild, and severe CAD groups. The PLR in the control group was significantly lower than those of mild and severe CAD groups. In multivariate logistic regression analysis, PLR was found to be an independent predictor of the presence of severe CAD (odds ratio: 1.043 [1.036-1.049], P < .001). Furthermore, there was a significant correlation between PLR and the severity of CAD (r = .370, P < .001) and CRP levels (r = .312, P < .001). In conclusion, PLR was independently and positively associated with the severity of coronary atherosclerosis. These results suggest that PLR is an easily available and cheap inflammatory indicator that can be used in predicting the severity of CAD.
