[PMID: 38152332 PMCID: PMC10751893 DOI: 10.1515/med-2023-0877] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/22/2023] [Revised: 11/24/2023] [Accepted: 11/24/2023] [Indexed: 12/29/2023] Open
Abstract
Studies have suggested that the progress of most kidney diseases from occurrence to course and subsequent related complications are closely related to inflammatory reaction. Increased common leukocytes count in the family (neutrophils, eosinophils, basophils, lymphocytes, etc.) are also involved in the tissue damage of kidney diseases. However, these studies are only traditional observational studies, which cannot prove whether there is a causal relationship between these four kinds of leukocytes count and kidney diseases. We aim to explore the causal relationship between these four kinds of leukocytes count and kidney diseases by Mendelian randomization (MR). Large sample size of the genome-wide association database of four cell traits (neutrophil, basophil, lymphocyte, and eosinophil cell counts) in the leukocyte family were used as exposure variables. The outcome variables were various renal diseases (including chronic renal failure, acute renal failure, hypertensive heart or/and kidney disease, hypertensive renal disease, disorders resulting from impaired renal tubular function, and type 1 diabetes with renal complications). The covariates used in multivariable MR are also four cell traits related to blood cells (neutrophil, basophil, lymphocyte, and eosinophil cell counts). Instrumental variables and single nucleotide polymorphic loci were identified (P < 5 × 10-8. Linkage disequilibrium R2 < 0.001). The causal relationships were studied by inverse variance weighted (IVW), weighted median, and MR-Egger regression. Sensitivity analysis was also performed. In our study, IVW analysis results showed that increased neutrophil cell count was a risk factor for chronic renal failure (OR = 2.0245861, 95% CI = 1.1231207-3.649606, P = 0.01896524), increased basophil cell count was a risk factor for chronic renal failure (OR = 3.975935, 95% CI = 1.4871198-10.62998, P = 0.005942755). Basophil cell count was not a risk factor for acute renal failure (OR = 1.160434, 95% CI = 0.9455132-1.424207, P = 0.15448828). Increased basophil cell count was a protective factor for hypertensive heart and/or renal disease (OR = 0.7716065, 95% CI = 0.6484979-0.9180856, P = 0.003458707). Increased basophil cell count was a risk factor for disorders resulting from impaired renal tubular function (OR = 1.648131, 95% CI = 1.010116-2.689133, P = 0.04546835). Increased lymphocyte cell count was a risk factor for hypertensive renal disease (OR = 1.372961, 95% CI = 1.0189772-1.849915, P = 0.03719874). Increased eosinophil cell count was a risk factor for type 1 diabetes with renal complications (OR = 1.516454, 95% CI = 1.1826453-1.944482, P = 0.001028964). Macrophage inflammatory protein 1b levels was a protective factor for renal failure (OR = 0.9381862, 95% CI = 0.8860402-0.9934013, P = 0.02874872). After multivariable MR was used to correct covariates (neutrophil, basophil, and lymphocyte cell counts), the correlation effect between increased eosinophil cell counts and type 1 diabetes with renal complications was still statistically significant (P = 0.02201152). After adjusting covariates (neutrophil, basophil, and eosinophil cell counts) with multivariable MR, the correlation effect between increased lymphocyte cell counts and hypertensive renal disease was still statistically significant (P = 0.02050226). This study shows that increased basophils can increase the relative risk of chronic renal failure and renal tubular dysfunction, and reduce the risk of hypertensive heart disease and/or hypertensive nephropathy, while increased basophil cell count will not increase the relative risk of acute renal failure, increased neutrophil cell count can increase the risk of chronic renal failure, increased lymphocyte cell count can increase the relative risk of hypertensive nephropathy, and increased eosinophil cell count can increase the relative risk of type 1 diabetes with renal complications. Macrophage inflammatory protein 1b levels was a protective factor for renal failure.

Abstract
INTRODUCTION The cardiovascular risk has been increased in chronic kidney disease associated with chronic inflammation and atherosclerosis. Decoy receptor 3, is a member of the TNF receptor superfamily and associated with inflammation and atherosclerosis. The aim of our study is to determine the relationship, between serum DcR3 levels and inflammatory markers in patients with renal transplantation, those receiving dialysis treatment and cases with chronic renal failure that did not receive replacement therapy, and to evaluate their correlation with USG findings. MATERIAL AND METHODS A total of 150 patients aged between 22-86 years, consisting of 4 groups, namely renal transplantation, dialysis, predialysis chronic kidney disease and control groups, were included in the study. Serum decoy receptor 3, VCAM-1, ICAM-1 and IL-8 measured with ELISA method. Carotid intima-media thickness and presence of carotis arter plaque performed by ultrasound probe, non-invasively. RESULTS All serum markers were higher in dialysis and pre-dialysis chronic kidney disease groups compared to renal transplant and control groups (p<0.05). Serum decoy receptor 3 level (median(min-max)) of renal transplant group (0.49ng/mL (0.19-1.65)) was higher than control group (0.35ng/mL (0.19-2.22)). There was no difference between patients receiving dialysis (0.89ng/mL (0.41-4.98)) and patients with pre-dialysis chronic kidney disease (0.71ng/mL (0.29-1.68)). There was no difference between patient groups in terms of the presence of plaque. CONCLUSION Although renal transplantation provides a significant improvement in the inflammatory process, not return completely. Inflammatory process associated with uremic milieu may predispose to atherosclerosis in patients with pre-dialysis chronic kidney disease and hemodialysis patients.

Abstract
Introduction. Hemodialysis patients are the group which oxidative stress is found more exacerbated. Ischemia modified albumin (IMA) is a new and sensitive marker for ischemia and oxidative stress. At current study we evaluated relation between IMA and biochemical parameters in hemodialysis patients.
Materials and Methods. Thirty-four patients on maintenance hemodialysis were included. Pre-hemodialysis and post-hemodialysis blood samples were taken. Serum IMA and biochemistry parameters were measured.
Results. There was a positive correlation between alkaline phosphatase (ALP) and IMA (r=0,268, p<0,05), CRP and IMA (r=0,452, p=0,007), parathormone and IMA (r=0,436, p=0,010), There was a negative correlation between albumin and IMA (r=-0,338, p=0,05). Multiple regression analysis was run to predict IMA levels from parathormone, CRP and creatinine the model statistically significantly predicted relation p<0,05, R=0,506, out of four two variables added statistically significant to the prediction, PTH (p=0,006), CRP (p=0,029). In multiregression analysis, IMA was found to be associated with PTH and CRP independent of creatinine value.
Conclusions. We showed for the first time that PTH is associated with IMA in hemodialysis patients, independent of the level of renal function.

Abstract
OBJECTIVES Neutrophil-lymphocyte ratio (NLR), platelet-lymphocyte ratio (PLR), and C-Reactive Protein (CRP) are markers of inflammation that are elevated in bipolar disorder (BD) and are also related to a higher risk of metabolic syndrome (MetS). This study aimed at investigating for the first time the association between NLR, PLR, and CRP and the metabolic status in BD. METHODS We assessed the association between biomarkers and the metabolic status: number of metabolic risk factors, presence of MetS, insulin sensitivity (Quantitative Insulin Sensitivity Check Index, QUICKI) and insulin resistance (Homeostatic Model Assessment for Insulin Resistance, HOMA-IR index), in a sample of 219 outpatients with BD. RESULTS 25.9% of the sample met the criteria for MetS. High levels of CRP were found in 12% of the sample. Older age, low PLR, high NLR, and high CRP levels significantly predicted a higher number of MetS risk factors (p < 0.001). Older age and low PLR were associated with a greater likelihood of developing MetS (p = 0.007). CONCLUSIONS Although further studies are needed to replicate and validate these findings, inflammatory biomarkers as CRP, PLR and NLR could be useful tools to identify patients with a BD at risk for a metabolic adverse outcome.

Abstract
Recent studies have shown that depletion of vitamin C is frequent in outpatient kidney transplant recipients (KTR) and that vitamin C is inversely associated with risk of death. Whether plasma vitamin C is associated with death-censored kidney graft failure remains unknown. We investigated KTR who participated in the TransplantLines Insulin Resistance and Inflammation Biobank and Cohort Study. The primary outcome was graft failure (restart of dialysis or re-transplantation). Overall and stratified (pinteraction < 0.1) multivariable-adjusted Cox regression analyses are presented here. Among 598 KTR (age 51 ± 12 years-old; 55% males), baseline median (IQR) plasma vitamin C was 44.0 (31.0-55.3) µmol/L. Through a median follow-up of 9.5 (IQR, 6.3‒10.2) years, 75 KTR developed graft failure (34, 26, and 15 events over increasing tertiles of vitamin C, log-rank p < 0.001). Plasma vitamin C was inversely associated with risk of graft failure (HR per 1-SD increment, 0.69; 95% CI 0.54-0.89; p = 0.004), particularly among KTR with triglycerides ≥1.9 mmol/L (HR 0.46; 95% CI 0.30-0.70; p < 0.001; pinteraction = 0.01) and among KTR with HDL cholesterol ≥0.91 mmol/L (HR 0.56; 95% CI 0.38-0.84; p = 0.01; pinteraction = 0.04). These findings remained materially unchanged in multivariable-adjusted analyses (donor, recipient, and transplant characteristics, including estimated glomerular filtration rate and proteinuria), were consistent in categorical analyses according to tertiles of plasma vitamin C, and robust after exclusion of outliers. Plasma vitamin C in outpatient KTR is inversely associated with risk of late graft failure. Whether plasma vitamin C‒targeted therapeutic strategies represent novel opportunities to ease important burden of graft failure necessitates further studies.

Abstract
Abstract
Background
Guillain–Barré Syndrome (GBS) is one of the most severe neurological diseases that causes marked disability and even death.
Aim
The aim of this study is to investigate the role of the neutrophil–lymphocyte ratio (NLR) as a prognostic marker for GBS and response to treatment with plasmapheresis.
Methods
Seventy-five subjects (35 GBS patients and 40 healthy controls) were recruited. Complete general and neurological examinations were performed and Hughes disability scale score was evaluated for assessing functional motor deficits in GBS patients. In addition, NLR, erythrocyte sedimentation rate, and C-reactive protein level were calculated.
Results
NLR was significantly higher in GBS patients than in controls (p < 0.001) and was significantly higher in axonal form than other demyelinating and mixed subtypes (p < 0.02). Patients with a poor outcome had a significantly high NLR than patients with a good outcome (p = 0.006). NLR was also positively correlated with Hughes disability scale score (p < 0.001). The cut-off value for NLR to predict a good response of patients to plasmapheresis was ≤ 4.4.
Interpretation
NLR may be a rapid, simple, inexpensive biomarker for predicting the severity of GBS, outcome of patients, and their response to plasmapheresis.

Abstract
After decades of pioneering and improvement, kidney transplantation is now the renal replacement therapy of choice for most patients with end-stage kidney disease (ESKD). Where focus has traditionally been on surgical techniques and immunosuppressive treatment with prevention of rejection and infection in relation to short-term outcomes, nowadays, so many people are long-living with a transplanted kidney that lifestyle, including diet and exposure to toxic contaminants, also becomes of importance for the kidney transplantation field. Beyond hazards of immunological nature, a systematic assessment of potentially modifiable-yet rather overlooked-risk factors for late graft failure and excess cardiovascular risk may reveal novel targets for clinical intervention to optimize long-term health and downturn current rates of premature death of kidney transplant recipients (KTR). It should also be realized that while kidney transplantation aims to restore kidney function, it incompletely mitigates mechanisms of disease such as chronic low-grade inflammation with persistent redox imbalance and deregulated mineral and bone metabolism. While the vicious circle between inflammation and oxidative stress as common final pathway of a multitude of insults plays an established pathological role in native chronic kidney disease, its characterization post-kidney transplant remains less than satisfactory. Next to chronic inflammatory status, markedly accelerated vascular calcification persists after kidney transplantation and is likewise suggested a major independent mechanism, whose mitigation may counterbalance the excess risk of cardiovascular disease post-kidney transplant. Hereby, we first discuss modifiable dietary elements and toxic environmental contaminants that may explain increased risk of cardiovascular mortality and late graft failure in KTR. Next, we specify laboratory and clinical readouts, with a postulated role within persisting mechanisms of disease post-kidney transplantation (i.e., inflammation and redox imbalance and vascular calcification), as potential non-traditional risk factors for adverse long-term outcomes in KTR. Reflection on these current research opportunities is warranted among the research and clinical kidney transplantation community.

Abstract
Objective The neutrophil-lymphocyte ratio (NLR) and platelet-lymphocyte ratio (PLR) are markers that can determine the presence of systemic inflammatory response. In this study, we examined the NLR and PLR levels in patients with heroin dependence compared to healthy controls. Methods The study sample included 90 male patients with heroin dependence aged 18 to 45 years and 60 healthy subjects who had similar socio-demographic characteristics as the patient group. The diagnoses of heroin dependence and other Axis I psychiatric disorders in the patient and control groups were screened with the Structured Clinical Interview for Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition (SCID-I). The extent of heroin addiction was assessed with the Addiction Severity Index (ASI). Results The mean NLR and PLR levels of patients with heroin dependence were significantly higher than the control subjects (p=0.031 and p<0.001, respectively). Positive correlations were found between NLR, PLR and duration of the disorder. Conclusion Our results indicate that inflammatory processes may play a role in the pathophysiology of heroin dependence.

[PMID: 28740332 PMCID: PMC5504948 DOI: 10.1155/2017/3578702] [Citation(s) in RCA: 48] [Impact Index Per Article: 6.9] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/07/2016] [Revised: 03/26/2017] [Accepted: 04/06/2017] [Indexed: 12/13/2022] Open
Abstract
Glibenclamide is the most widely used sulfonylurea drug for the treatment of type 2 diabetes mellitus (DM). Recent studies have suggested that glibenclamide reduced adverse neuroinflammation and improved behavioral outcomes following central nervous system (CNS) injury. We reviewed glibenclamide's anti-inflammatory effects: abundant evidences have shown that glibenclamide exerted an anti-inflammatory effect in respiratory, digestive, urological, cardiological, and CNS diseases, as well as in ischemia-reperfusion injury. Glibenclamide might block KATP channel, Sur1-Trpm4 channel, and NOD-like receptor pyrin domain containing 3 (NLRP3) inflammasome activation, decrease the production of proinflammatory mediators (TNF-α, IL-1β, and reactive oxygen species), and suppress the accumulation of inflammatory cells. Glibenclamide's anti-inflammation warrants further investigation.

Vitamin C Depletion and All-Cause Mortality in Renal Transplant Recipients. Nutrients 2017; 9:nu9060568. [PMID: 28574431 PMCID: PMC5490547 DOI: 10.3390/nu9060568] [Citation(s) in RCA: 17] [Impact Index Per Article: 2.4] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/11/2017] [Revised: 05/25/2017] [Accepted: 05/30/2017] [Indexed: 02/05/2023] Open
Abstract
Vitamin C may reduce inflammation and is inversely associated with mortality in the general population. We investigated the association of plasma vitamin C with all-cause mortality in renal transplant recipients (RTR); and whether this association would be mediated by inflammatory biomarkers. Vitamin C, high sensitive C-reactive protein (hs-CRP), soluble intercellular cell adhesion molecule 1 (sICAM-1), and soluble vascular cell adhesion molecule 1 (sVCAM-1) were measured in a cohort of 598 RTR. Cox regression analyses were used to analyze the association between vitamin C depletion (≤28 µmol/L; 22% of RTR) and mortality. Mediation analyses were performed according to Preacher and Hayes's procedure. At a median follow-up of 7.0 (6.2-7.5) years, 131 (21%) patients died. Vitamin C depletion was univariately associated with almost two-fold higher risk of mortality (Hazard ratio (HR) 1.95; 95% confidence interval (95%CI) 1.35-2.81, p < 0.001). This association remained independent of potential confounders (HR 1.74; 95%CI 1.18-2.57, p = 0.005). Hs-CRP, sICAM-1, sVCAM-1 and a composite score of inflammatory biomarkers mediated 16, 17, 15, and 32% of the association, respectively. Vitamin C depletion is frequent and independently associated with almost two-fold higher risk of mortality in RTR. It may be hypothesized that the beneficial effect of vitamin C at least partly occurs through decreasing inflammation.

Abstract
INTRODUCTION Chronic inflammation is a major risk factor in the pathogenesis of cardiovascular disease in end-stage renal disease (ESRD) patients. Epicardial adipose tissue (EAT) is the true visceral fat depot of the heart. The relationship between coronary artery disease and EAT was shown in healthy subjects and ESRD patients. In the present study we aimed to investigate the relationship between EAT and inflammation parameters including neutrophil-to-lymphocyte ratio (NLR) in hemodialysis (HD) patients. MATERIAL AND METHODS Forty-three HD patients (25 females, 18 males; mean age: 64.1 ±11.9 years) receiving HD and 30 healthy subjects (15 females, 15 males; mean age: 59.1 ±10.8 years) were enrolled in the study. Epicardial adipose tissue measurements were performed by echocardiography. RESULTS Neutrophil-to-lymphocyte ratio levels were significantly higher in HD patients than in the healthy control group. Hemodialysis patients were separated into two groups according to their median value of NLR (group 1, NLR < 3.07 (n = 21) and group 2, NLR ≥ 3.07 (n = 22)). Group 2 patients had significantly higher EAT, C-reactive protein and ferritin levels, while albumin levels were significantly lower in this group. In the bivariate correlation analysis, EAT was positively correlated with NLR (r = 0.600, p < 0.001) and ferritin (r = 0.485, p = 0.001) levels. CONCLUSIONS Neutrophil-to-lymphocyte ratio was found to be an independent predictor of EAT in HD patients (odds ratio = 3.178; p = 0.008). We concluded that this relationship might be attributed to increased inflammation in uremic patients.

Abstract
BACKGROUND Cardiovascular disease (CVD) is the leading cause of mortality and morbidity in patients with chronic kidney disease (CKD) including kidney transplant recipients (KTR). Secondary lipid metabolism disorders, endothelial dysfunction, and inflammation enhance the risk of CVD development in these patients. The aim of the present study was to investigate the lipid profile, adiponectin, leptin, nitric oxide (NO), and high sensitivity C-reactive protein (hs-CRP) levels in KTR and to compare these parameters with those of the patients with chronic renal failure (CRF), hemodialysis (HD) patients, and healthy controls. METHODS Serum adiponectin and leptin levels were measured by radioimmunoassay; hs-CRP was determined immunoturbidimetrically. Determination of NO was based on the Griess reaction. RESULTS Compared with the control group, serum NO and adiponectin levels were significantly higher in the KTR, CRF, and HD groups; hs-CRP levels were significantly higher in the KTR and HD groups; leptin levels were significantly higher in the KTR. In addition, serum NO level was significantly higher in the KTR compared to CRF cases. Adiponectin correlated positively with high density lipoprotein-cholesterol in the control and patient groups. A positive correlation was observed between hs-CRP and NO in the KTR and the patients with CRF. Serum adiponectin levels were inversely correlated with hs-CRP and leptin in the HD group. CONCLUSION KTR suffer from inflammation and accompanying changes in levels of adipocytokines and NO which contribute to the increased risk of CVD in these patients.

Abstract
OBJECTIVES Elevated neutrophil-to-lymphocyte ratios (NLR) and platelet-to-lymphocyte ratios (PLR) at time of cancer diagnosis have been associated to poor prognosis in various cancers. There is no data on their natural progression before the cancer diagnosis has been established. We aim to evaluate whether or not the annual changes in these ratios could be early indicators of lung cancer development. MATERIALS AND METHODS Participants recruited into the Pamplona International Early Lung Cancer Action Program (P-IELCAP, n=3061) between 2001 and 2015 were considered. Complete blood counts (CBC) were registered at annual intervals between enrolment and time of diagnosis. Linear regression was used to calculate the mean annual change in NLR and PLR in participants with ≥3CBCs. Changes were expressed relative to baseline values. Lung cancer incidence density and lung cancer risk (Cox regression analysis) were calculated for different NLR and PLR annual thresholds (<0%, ≥0%, ≥1%, ≥2%, ≥4%). Results were compared to a matched group of participants who did not develop lung cancer. RESULTS After a median follow-up of 80 months and a median of 4 (IQR 3-6) CBCs, subjects who developed lung cancer (n=32) showed greater NLR and PLR annual changes than matched controls (n=103) (2.56% vs. 0.27% [p=0.25] per year; and 3.75% vs. 0.33% [p=0.053] per year, respectively). Lung cancer incidence density per 100 person-years increased with higher annual NLR and PLR thresholds. On multivariable analysis (adjusting for emphysema and baseline lung-function), NLR and PLR were not significant lung cancer predictors. However, among individuals with emphysema, for each relative unit increase in PLR, lung cancer risk increased 5% (p=0.03). There was a significant supra-additive risk effect between PLR increase and emphysema. Annual NLR change was not a significant lung cancer predictor. CONCLUSION In a lung cancer screening setting, the assessment of annual PLR change could help predict lung cancer development.

Abstract
Introduction Several theories attempt to explain the pathophysiology of sudden hearing loss. Objective The objective of this study was to investigate the possible role of inflammation and atherothrombosis in sudden hearing loss patients through the neutrophil-to-lymphocyte ratio and mean platelet volume. Methods Study design – retrospective cross-sectional historical cohort. This study was conducted on two groups: one with 59 individuals diagnosed with sudden hearing loss, and other with 59 healthy individuals with the same characteristics of gender and age distribution, neutrophil-to-lymphocyte ratio and mean platelet volume levels were measured in patients diagnosed with sudden hearing loss as well as in the control group, and it was verified whether these results interfered for a better or worse prognosis with treatment of sudden deafness. Results Neutrophil-to-lymphocyte ratio levels are much higher in patients diagnosed with sudden hearing loss compared to the control group. Similarly, mean levels of neutrophil-to-lymphocyte ratio are higher in non-recovered versus recovered patients (p = 0.001). However, we could not find a correlation with mean platelet volume levels (p > 0.05). Conclusion Neutrophil-to-lymphocyte ratio is a quick and reliable indicator regarding diagnosis and prognosis of sudden hearing loss; on the other hand, mean platelet volume may be considered a less important indicator in this aspect.

Abstract
BACKGROUND Neutrophil-lymphocyte ratio (NLR) is an emerging biomarker of inflammation and predicts poorer outcome in cancer surgery. The prognostic value of NLR in cardiovascular surgery is unclear. METHODS Systematic review and meta-analysis of studies of in cardiovascular surgical patients were conducted to assess the role of perioperative NLR in predicting post-operative mortality and morbidity. Electronic searches were conducted on Ovid Medline, EMBASE, Cochrane Central Register of Controlled Trials and Cochrane Database of Systemic Reviews for all prospective clinical studies reporting on NLR and post-operative morbidity and mortality in cardiovascular surgical patient population. Our primary end point was all-cause post-operative mortality and the secondary end point was post-operative morbidity. Mortality outcome from prospective studies were pooled for a meta-analysis using a random-effect model. RESULTS Of the 999 citations identified, five studies with 3487 patients met the inclusion criteria. In a pooled analysis of three prospective studies of 3108 patients, a preoperative increase in NLR (>3.3 in cardiac surgery, >5 in vascular surgery) was associated with increased mortality at a mean follow-up of 34.8 months (hazard ratio 1.85, 95% confidence interval 1.46-2.36; P < 0.00001). Raised NLR value was also associated with increased cardiac mortality, amputation in vascular operations and raised risk of post-operative re-intubation. CONCLUSIONS Elevated NLR were associated with increased long-term mortality and morbidity after major cardiac and vascular surgery. NLR may guide perioperative management and risk-stratification of patients.

Abstract
INTRODUCTION Diabetic nephropathy (DN) is a common complication in diabetics. Recent evidence suggests that neutrophil-lymphocyte ratio (NLR) affects the development and acceleration of some diabetic complications. Scholars have rarely investigated the relationship between DN and NLR. This study aims to evaluate the relationship between DN and NLR and estimate whether or not NLR is a reliable marker for early-stage DN. PATIENTS AND METHODS The study included 253 patients with type 2 diabetes mellitus, 115 of whom have early-stage DN. The control group was composed of 210 healthy age- and sex-matched subjects. RESULTS The NLR values of the patients with diabetes were significantly higher than those of the healthy controls (P < 0·001), and the NLR values of the patients with early-stage DN were higher than those of the patients without DN (P < 0·001). Logistic regression analysis showed that the risk predictors of DN include NLR, creatinine, total cholesterol, systolic blood pressure, HbA1c and insulin resistance. NLR (P = 0·004, EXP(B) = 2·088, 95% CI = 1·271-3·429) levels positively correlated with DN. The DN odds ratio increased by a factor of 2·088 (95% CI, 1·271-3·429) for every one unit increase in NLR. CONCLUSIONS Increased NLR was significantly associated with DN, and high NLR values may be a reliable predictive marker of early-stage DN.

Abstract
OBJECTIVE End stage renal disease (ESRD) has a high worldwide prevalence and incidence. Peritonitis is one of the leading causes of hospitalization in peritoneal dialysis patients. Although inflammatory markers show increased inflammatory responses, cellular immune response was decreased in ESRD patients. Leptin is an adipocyte-derived hormone that has activity in energy, nutrition and immune system. Neutrophil to lymphocyte ratio (N/L) was emerged as a predictive and prognostic criterion in many instances. In this study, we aimed to investigate the relationships between increased inflammation in peritoneal dialysis patients and leptin, N/L ratio. MATERIALS AND METHODS Forty-one ESRD patients, who were been at least 12 months of peritoneal dialysis therapy, were included in the study. Patients' demographic properties were recorded. Serum leptin level, WBC count, C-reactive protein, erythrocyte sedimentation rate and biochemical markers were measured. Patients with active viral or bacterial infection, malignancy, inflammatory disease, immunosuppressive medication users were all excluded from the study. Age and sex-matched healthy control group was included in the study only for their leptin levels. RESULTS The measured mean serum leptin level of the patient group was statistically significantly higher than control group (1624.88±1608.16 and 416±439.85). The calculated mean peritonitis incidence was 0.041±0.047 peritonitis/per year. The number of peritonitis attack was significantly correlated with duration of peritoneal dialysis, body mass index (BMI), age and presence of cardiovascular disease. Serum leptin level was significantly correlated with sex, age, primary cause of ESRD, BMI, blood glucose level and duration of peritoneal dialysis (PD). CONCLUSION We detected that ESRD patients have higher serum leptin levels compare to healthy adults. Increased leptin was correlated with sex, age, BMI, primary cause of ESRD and serum glucose level. Number of peritonitis attack and peritonitis incidence was significantly correlated with the duration of PD, BMI and sex. We weren't able to show the predictive N/L value in PD patients in case of peritonitis.

Abstract
Background In this study we investigated the potential of neutrophil/lymphocyte ratio (NLR), platelet/lymphocyte ratio (PLR), mean platelet volume (MPV), and red cell width distribution (RDW) as new inflammatory markers to identify chronic inflammations during symptom-free periods in children diagnosed with Familial Mediterranean Fever (FMF). Material/Methods The study included 153 children diagnosed with FMF based on the Tel-Hashomer Criteria, and 90 healthy volunteers. Hospital records were obtained to collect NLR, PLR, MPV, RDW, and FMF scores and the FMF mutation analyses of the patients enrolled in the study. Data on proteinuria were also collected and defined as a protein/creatinine ratio >0.2. Results NLR, PLR, MPV, and RDW were significantly higher in symptom-free FMF patients than in the control group. C-reactive protein values also weakly correlated with NLR, PLR, MPV, and RDW, but the correlation was not statistically significant. NLR had the strongest correlation with CRP. The NLR cut-off point to indicate subclinical inflammation in symptom-free FMF patients was calculated to be 1.65. Conclusions NLR, PLR, MPV, and RDW are potential subclinical inflammation markers in patients with FMF. NLR, PLR, MPV, and RDW values are higher in patients with FMF during symptom-free periods. NLR was found to be the most reliable marker for subclinical inflammation when compared to PLR, MPV, and RDW. We also found that these markers are not significantly higher in proteinuric patients when compared with levels in non-proteinuric patients.

Am J Otolaryngol 2014; 35:699-702. [PMID: 25219290 DOI: 10.1016/j.amjoto.2014.08.004] [Citation(s) in RCA: 18] [Impact Index Per Article: 1.8] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/30/2014] [Revised: 08/05/2014] [Accepted: 08/14/2014] [Indexed: 11/25/2022]
Abstract
We aimed to investigate the relationship between peripheral vertigo and inflammation by using the neutrophil-to-lymphocyte ratio (NLR) as an inflammatory marker. We recruited 103 patients with peripheral vertigo (71 women, 32 men; mean age, 39.8 ± 14.7 years) who presented to the Otolaryngology Department of Dumlupinar University Hospital. Vertigo patients with systemic diseases, neurological disorders, malignancy or any inflammatory disease that could alter the NLR were excluded from the study. We also enrolled 103 age- and sex-matched healthy subjects (controls; 82 women, 21 men; mean age, 36.7 ± 13.5 years) who underwent routine checkups in our hospital. The vertigo patients underwent full otolaryngologic and neurologic examinations and audiometric tests to rule out any other pathology causing the peripheral vertigo. NLR was calculated in all subjects and was compared between the patient and control groups. There were no significant differences between the study and control groups in terms of lipid profiles, liver-function tests, white blood cell (WBC) count, hemoglobin level, mean platelet volume, and vitamin B12 and folate levels. The mean NLR was significantly higher in the patients than in the controls (P<0.05). In conclusion, this study, which was the first to investigate the relationship between the NLR and peripheral vertigo, found that the NLR is significantly higher among peripheral vertigo patients than among healthy controls. This result suggests that the NLR is a novel potential marker of stress in peripheral vertigo patients.

Abstract
INTRODUCTION Long-term exposure to dialysis solutions is an important contributor to the ongoing inflammatory process in peritoneal dialysis (PD) patients. Some studies have shown amelioration of this adverse effect with biocompatible solutions. We aimed to compare the neutrophil-to-lymphocyte (N/L) ratio in PD patients using biocompatible and standard solutions and to find out the association between N/L ratio and peritonitis indices. MATERIALS AND METHODS This was a cross-sectional, multicenter study involving 120 prevalent PD patients. Seventy-one patients (59%) were using biocompatible solutions and 49 patients (41%) were using standard solutions. From blood samples, N/L ratio and platelet-to-lymphocyte ratio were calculated and mean platelet volume, erythrocyte sedimentation rate and hs-CRP values were detected. Data regarding the peritonitis rate and time to first peritonitis episode were also recorded. RESULTS Biocompatible and standard groups were similar regarding age and gender. N/L ratio and hs-CRP levels have been found significantly higher in patients using biocompatible solutions (3.75 ± 1.50 vs. 3.27 ± 1.3, p = 0.04 and 3.2 ± 2.5 vs. 1.8 ± 2.0, p < 0.01, respectively). Peritonitis rates and time to the first peritonitis episode were found similar in patients using both types of solutions (0.23 ± 0.35 vs. 0.27 ± 0.32, p = 0.36 and 32.8 ± 35.8 vs. 21.5 ± 26.9 months, p = 0.16, respectively). DISCUSSION N/L ratio was significantly higher in biocompatible solution users in parallel to hs-CRP levels, so biocompatible solutions seem to be related with increased inflammation in PD patients. Although we cannot make a certain explanation, we assume that there may be an association between acidity of the peritoneal content and virulence of microorganisms.

Abstract
BACKGROUND Patients on continuous ambulatory peritoneal dialysis (CAPD) and hemodialysis have accelerated atherosclerosis associated with an increase in cardiovascular morbidity and mortality. Atherosclerosis is associated with increased arterial stiffness (AS), endothelial dysfunction and elevated oxidative stress (OS) and inflammation. We aimed to investigate the relationship between oxidative stress status, arterial stiffness, hepcidin and fibroblast growth factor-21 (FGF-21) levels in CAPD patients. METHODS As a prospective observational study, we analyzed 56 CAPD patients, aged between 30 and 63 years. Serum hepcidin, FGF-21 levels, OS status and AS were determined. Arterial stiffness was measured by flow-mediated dilatation (FMD). Oxidative stress status was determined by total antioxidant status, total oxidant status (TOS) and oxidative stress index (OSI). RESULTS FMD was negatively correlated with TOS, OSI, hepcidin and FGF-21 (r: -0.313, p: 0.020; r: -0.0331, p: 0.014; r: -0.498, p < 0.001; r: -0.403, p: 0.002, respectively). OSI was positively correlated with hepcidin, parathormone and negatively correlated with FMD (r: 0.278, p: 0.040; r: 0.462, p < 0.001; r: -0.0331, p: 0.014, respectively). CONCLUSION There are many factors affecting arterial stiffness in CAPD patients. In our study, higher levels of OS status, hepcidin and FGF-21 were independent determinants of arterial stiffness in PD patients. Therefore, definition and improvement of these new parameters will be helpful to reduce the cardiovascular disease risk and mortality in CAPD patients.

Abstract
OBJECTIVES/HYPOTHESIS Bell palsy can be defined as an idiopathic, acute, facial nerve palsy. Although the pathogenesis of Bell palsy is not fully understood, inflammation seems to play important role. Neutrophil-to-lymphocyte (NLR) ratio was defined as a novel potential marker to determine inflammation and it is routinely measured in peripheral blood. Our goal was to investigate the relationship between Bell palsy and inflammation by using NLR. STUDY DESIGN Retrospective study. METHODS The 54 patients who were followed up for Bell palsy for a period of 1 to 3 years, along with 45 age- and sex-matched controls, were included in the study. An automated blood cell counter was used for NLR measurements. All patients were treated with prednisone, 1 mg/kg per day with a progressive dose reduction. Patients were classified according to the House-Brackmann grading system at posttreatment period. Those with House-Brackmann grade I and grade II were regarded as satisfactory recovery; and those with House-Brackmann grade III to grade VI were regarded as nonsatisfactory recovery. RESULTS The mean NLR and neutrophil values in patients with Bell palsy were significantly higher than in the control group (P=0.001 and P<0.001, respectively). In addition, NLR levels were higher in nonsatisfactory recovered patients compared with satisfactory recovered ones (P<0.001). CONCLUSION This is the first study investigating the relationship between NLR levels and Bell palsy and its prognosis. Our result suggest that while evaluating Bell palsy patients, NLR might be taken into account as a novel potential marker to predict the patients' prognosis. LEVEL OF EVIDENCE 3b.

Abstract
BACKGROUND Inflammatory markers show significant associations with cardiovascular events and all-cause mortality after kidney transplantation. Neopterin, reflecting interferon-γ-release, may better reflect the proinflammatory state of recipients than less specific markers. METHODS Kidney transplant recipients in the Assessment of LEscol in Renal Transplant (ALERT) trial were examined and investigated for an association between serum neopterin and subsequent clinical events: graft loss, major cardiovascular events (MACE) and all-cause mortality. RESULTS After adjustment for established and emerging risk factors neopterin expressed as neopterin-to-creatinine ratio was significantly associated with MACE (p = 0.009) and all-cause mortality (p = 0.002). Endpoints were more frequent with increasing quartiles of neopterin-to-creatinine ratio. The incidence rates of MACE and all-cause mortality were significantly increased in the upper quartiles compared with the first. CONCLUSIONS This long-term prospective analysis in stable kidney allograft recipients suggests that neopterin is associated with long-term risk of cardiovascular events and all-cause mortality, but not renal outcomes.

Abstract
INTRODUCTION Diabetic retinopathy (DR) is the most common complication and cause of visual impairment in diabetes patients. The pathogenesis is not fully understood, but several studies have suggested that inflammation plays an important role. The neutrophil-to-lymphocyte ratio (NLR) was defined as a novel potential marker to determine inflammation. We aimed to evaluate the relationship between DR and inflammation by using NLR. PATIENTS AND METHODS The study was included 58 patients diagnosed with type 2 diabetes mellitus. Twenty-four of them had DR. The control group was composed of 52 age- and sex-matched healthy subjects. Retinopathy was graded using the International Clinical Diabetic Retinopathy Disease Severity Scale. RESULTS NLR values of the diabetes patients were significantly higher than those of the healthy control group (P<0.001), and NLR levels of the patients with DR were higher than those of the patients without DR (P<0.001). In addition, NLR values were correlated with the presence of DR and DR grades (r=0.466, P<0.001; and r=0.630, P<0.001, respectively). CONCLUSIONS According to our knowledge, this is the first study investigating the relationship between NLR, which is an inflammatory marker, and DR and its severity. Our results suggest that while evaluating diabetes patients in terms of DR, higher NLR values may be a remarkable marker.

Abstract
Chronic inflammation was found to be correlated with coronary (CAC) and thoracic peri-aortic calcification (TAC) in end-stage renal disease (ESRD) patients. Neutrophil-to-lymphocyte ratio (NLR) was introduced as a potential marker to determine inflammation in cardiac and noncardiac disorders. Data regarding NLR and its association with TAC and CAC are lacking. We aimed to determine the relationship between NLR and vascular calcification in ESRD patients. This was a cross-sectional study involving 56 ESRD patients (22 females, 34 males; mean age, 49.9 ± 14.2 years) receiving peritoneal dialysis or hemodialysis for ≥6 months in the Dialysis Unit of Necmettin Erbakan University. TAC and CAC scores were measured by using an electrocardiogram-gated 64-multidetector computed tomography. NLR was calculated as the ratio of the neutrophils and lymphocytes. There was a statistically significant correlation between NLR, TACS and CACS in ESRD patients (r = 0.43, P = 0.001 and r = 0.30, P = 0.02, respectively). The stepwise linear regression analysis revealed that age, as well as NLR were independent predictors of TACS. However, increased age was the only independent predictor of CACS according to linear regression analysis. Simple calculation of NLR can predict vascular calcification in ESRD patients.

Abstract
OBJECTIVES The aim of this study was to evaluate the efficiency of ischemia-modified albumin (IMA) for predicting major adverse cardiovascular events (MACE) in continuous ambulatory peritoneal dialysis (CAPD) patients. DESIGN AND METHODS A prospective observational study was conducted with 120 CAPD patients and 37 healthy volunteers. Demographic and clinical data were collected. The primary end point is the occurrence of MACE. RESULTS A total of 157 participants with a mean age of 43.64 years finally completed this study. The CAPD patients had a significantly high rate of MACE (P=0.001) and high levels of IMA than healthy controls (P<0.001). Compared with CAPD patients with normal levels of IMA, the CAPD patients with high levels of IMA (>85 kU/L) had lower non-MACE survival rate (P<0.001), which indicated that the high IMA CAPD patients may suffer a high rate of MACE. In addition, the high IMA CAPD patients also had a low level of serum albumin (P<0.001) and hemoglobin (P=0.018). The correlation analysis showed that the serum albumin level was the most effective factor influencing IMA (B=-0.967, P<0.001). CONCLUSIONS CAPD patients with high levels of IMA had a high incidence rate of MACE. IMA was a good predictive marker of MACE and might be important in cardiovascular risk stratification of CAPD patients.

Abstract
The pathogenesis of acute myocardial infarction is known to be mediated by systemic, intraplaque and myocardial inflammatory processes. Among different immune cell subsets, compelling evidence now indicates a pivotal role for neutrophils in acute coronary syndromes. Neutrophils infiltrate coronary plaques and the infarcted myocardium and mediate tissue damage by releasing matrix-degrading enzymes and reactive oxygen species. In addition, neutrophils are also involved in post-infarction adverse cardiac remodelling and neointima formation after angioplasty. The promising results obtained in preclinical modelswith pharmacological approaches interfering with neutrophil recruitment or function have confirmed the pathophysiological relevance of these immune cells in acute coronary syndromes and prompted further studies of these therapeutic interventions. This narrative review will provide an update on the role of neutrophils in acute myocardial infarction and on the pharmacological means that were devised to prevent neutrophil-mediated tissue damage and to reduce post-ischaemic outcomes.
