Pediatr Nephrol 2024; 39:1567-1576. [PMID: 38103065 DOI: 10.1007/s00467-023-06234-z] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/23/2023] [Revised: 11/10/2023] [Accepted: 11/13/2023] [Indexed: 12/17/2023]
Abstract
BACKGROUND Systemic inflammation (SI) is linked to chronic kidney disease (CKD) progression and multiple complications. Data regarding SI biomarkers in pediatric patients are scarce. This case-control and cross-sectional study investigates the correlation of neutrophil-lymphocyte ratio (NLR), platelet-lymphocyte ratio (PLR), total iron binding capacity (TIBC) and serum albumin to serum interleukin-6 (IL-6). METHODS NLR and PLR were measured in 53 patients (median age: 12.9 years), including 17 on dialysis and 36 with a median glomerular filtration rate of 39 ml/min/1.73m2, and in 25 age and sex-matched healthy controls. Iron profile, serum albumin and IL-6 were measured in the patient group. IL-6 levels > 3rd quartile were classified as high. RESULTS Patients presented higher NLR and PLR and particularly those on dialysis (p < 0.001 and p = 0.001). We observed a significant correlation between natural logarithm (ln) of IL-6 (lnIL-6) and NLR (rs = 0.344, p = 0.014), serum albumin (rs = -0.350, p = 0.011) and TIBC (rs = -0.345, p = 0.012) after adjustment for CKD stage, while the correlation between lnIL-6 and PLR was not significant (rs = 0.206, p = 0.151). Combination of NLR, serum albumin and TIBC predicted high IL-6 (13 patients) with an AUC of 0.771 (95% CI 0.608-0.943). Pairing of NLR ≥ 1.7 and TIBC ≤ 300 μg/dL exhibited the highest sensitivity (76.9%), while incorporating serum albumin ≤ 3.8 g/dL along with them achieved the highest specificity (95%) for detecting high IL-6 levels. CONCLUSION Both NLR and PLR levels increase in CKD, especially in patients on chronic dialysis. NLR, rather than PLR, along with TIBC and serum albumin, are associated with IL-6 in pediatric CKD.

Abstract
Abstract
Objective
To assess the association between the neutrophil-to-lymphocyte ratio (NLR) and platelet-to-lymphocyte ratio (PLR) with all-cause mortality in Peruvian patients with chronic kidney disease (CKD) attending a tertiary hospital.
Methods
We conducted a retrospective cohort study in adults with CKD in stages 1–5. The outcome variable was mortality and as variables of exposure to NLR and PLR. Both ratios were categorized as high with a cutoff point of 3.5 and 232.5, respectively. We carried out a Cox regression model and calculated crude and adjusted hazard ratios (HR) with their 95% confidence interval (95% CI).
Results
We analyzed 343 participants with a mean age of 78.3 (± 11.9) years and 62.9% (n = 216) men. The median follow-up time was 2.45 years (2.08–3.08), and the frequency of deaths was 17.5% (n = 60). The mortality of patients with high NLR was 28% compared to 15.7% of the group with normal NLR, and the mortality was 35.7% in those with high PLR and 15.6% in those with normal PLR. In the crude analysis, the high NLR and PLR were significantly associated with all-cause mortality (HR = 2.01; 95% CI 1.11–3.66) and (HR = 2.58; 95% CI 1.31–5.20). In the multivariate model, after adjusting for age, sex, serum creatinine, albumin and hemoglobin, the high NLR and PLR remained as independent risk factors for all-cause mortality (aHR = 1.97; 95% CI 1.05–3.69) and (aHR = 2.62; 95% CI 1.25–5.51), respectively.
Conclusion
Our study suggests the relationship between high NLR and PLR with all-cause mortality in patients with CKD.

Abstract
BACKGROUND Chronic kidney disease (CKD) patients have high levels of inflammatory mediators. These inflammatory mediators contribute to the increased risk of cardiovascular events and all-cause mortality. Platelet-lymphocyte ratio (PLR) has recently been recognized as a novel inflammatory marker and has been shown to be associated with the prognosis in CKD patients. However, the quality of these studies varies and their results are controversial. The purpose of this meta-analysis was to investigate the relationship between PLR and all-cause mortality in CKD patients. METHODS A systematic literature search of PubMed, EMBASE, CENTRAL and ISI Web of Science was conducted. The databases were searched from their inception dates up to the latest issue (31 October 2021). Two reviewers independently searched the databases and screened studies. Data were extracted using a standardized collection form. Meta-analysis was performed to compare PLR values between CKD and non-CKD patients, and to investigate the association between PLR and all-cause mortality in CKD patients. This meta-analysis is reported in adherence to Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA). RESULTS A total of 11 studies involving 4244 participants were selected. The pooled data indicated that PLR values were significantly higher in CKD patients than non-CKD controls (weighted mean difference = 21.6, 95% CI 17.39-25.81, p < 0.01), and PLR is associated with an increased risk of all-cause mortality in CKD patients (hazard ratio = 2.49, 95% CI 1.78-3.49, p < 0.01). CONCLUSIONS Patients with CKD have higher PLR values compared to non-CKD patients. Meanwhile, PLR values were highly associated with all-cause mortality in CKD patients. PLR is a valid predictor as a clinically accessible indicator for patients with CKD.

Nefrologia 2022; 42:163-170. [PMID: 36153912 DOI: 10.1016/j.nefroe.2021.06.005] [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: 02/07/2021] [Accepted: 06/06/2021] [Indexed: 06/16/2023] Open
Abstract
INTRODUCTION Chronic inflammation and the underlying cardiovascular comorbidity are still current problems in chronic hemodialysis patients. There are few studies comparing the "dialysis dose" with the degree of inflammation in the patient. Our main objective was to determine whether there is a relationship between serum C-reactive protein (CRP) levels and the "dialysis dose" (Kt / V) using ionic dialysance. METHODS Multicenter cross-sectional study. 536 prevalent chronic hemodialysis patients were included. CRP levels, neutrophil-lymphocyte ratio (NLR) and platelet-lymphocyte ratio (PLR) were collected. Kt was obtained by ionic dialysance and urea distribution volume was calculated from the Watson's formula. The sample was divided into two groups, taking the median CRP as the cut-off point. Dialysis adequacy obtained in each group was compared. Finally, a logistic regression model was carried out to determine the variables with the greatest influence. RESULTS Median CRP was 4.10 mg/L (q25-q75: 1.67-10) and mean Kt/V was 1.48 ± 0.308. Kt/V was lower in the patients included in the high inflammation group (p = 0.01). In the multivariate logistic regression, the "high" levels of CRP were directly correlated with the Log INL (p < 0.001) and inversely proportional with serum albumin values (p = 0.014), Kt/V (p = 0.037) and serum iron (p < 0.001). CONCLUSION The poorer adequacy in terms of dialysis doses, lower Kt / V values, may contribute to a higher degree of inflammation in chronic hemodialysis patients.

Abstract
Backgrounds Neutrophil-to-lymphocyte ratio (NLR), a surrogate marker of systemic response to physiological stress, is used for prognosis prediction in many diseases. However, the usefulness of this marker for predicting acute kidney injury (AKI) progression is unclear. Methods This retrospective study was based on the Chang Gung Research Database. Patients admitted to the intensive care unit with a diagnosis of stage 1 or 2 AKI were identified. The primary outcome was a composite of progression to stage 3 AKI, requirement of renal replacement therapy, or 14-day in-hospital mortality. The association between NLR and the primary outcome was examined using a logistic regression model and multivariable analysis. The nonlinearity and cutoff points of this relationship were determined using a restricted cubic spline model. Results A total of 10,441 patients were enrolled. NLR level at the time of stage 1–2 AKI diagnosis was a marker of adverse outcomes. After adjustment for confounders, NLR was independently associated with the composite outcome of AKI progression, renal replacement therapy, or mortality. The restricted cubic spline model revealed a J-shaped curve, with the lowest odds ratio for an NLR between 7 and 38. Subgroup analysis revealed linear and J-shaped relationships between NLR and the primary outcome in patients admitted to the intensive care unit for medical reasons and for cardiovascular surgery, respectively. Conclusions NLR is an independent marker of AKI progression and in-hospital mortality. Because it is readily available in daily practice, it might be used for risk stratification in the AKI population. Graphic abstract ![]()

Abstract
Introduction Diabetes mellitus causes serious complications such as diabetic nephropathy. Diabetic nephropathy is now the most common reason of chronic kidney disease. Inflammation plays a crucial role in development and progression of diabetic nephropathy. The aim of this study was to evaluate the relationship of Inflammatory markers (neutrophil-to-lymphocyte ratio and platelet-to-lymphocyte ratio) with diabetic nephropathy in Syrian patients. Materials and methods A total of 158 patients with type 2 diabetes mellitus were distributed into three groups according to urinary albumin-to-creatinine ratio: Group A, type 2 diabetic patients with normoalbuminuria (urinary albumin-to-creatinine ratio <30 mg/g); Group B, type 2 diabetic patients with microalbuminuria (urinary albumin-to-creatinine ratio = 30–300 mg/g); Group C, type 2 diabetic patients with macroalbuminuria (urinary albumin-to-creatinine ratio ≥300 mg/g). Levels of inflammatory markers (neutrophil-to-lymphocyte ratio and platelet-to-lymphocyte ratio) were recorded and compared among the three groups. Results Significant differences were detected between the groups in terms of neutrophil-to-lymphocyte ratio (p = 0.000) and platelet-to-lymphocyte ratio (p = 0.000). Receiver operating characteristic curve analysis of inflammatory markers and microalbuminuria prediction demonstrated an area under curve (AUC) of 0.869 for neutrophil-to-lymphocyte ratio (confidence interval: 0.813–0.926, p = 0.000) and 0.739 for platelet-to-lymphocyte ratio (confidence interval: 0.662–0.815, p = 0.000). Conclusion Increased neutrophil-to-lymphocyte ratio and platelet-to-lymphocyte ratio were significantly correlated with diabetic nephropathy, and high neutrophil-to-lymphocyte ratio & platelet-to-lymphocyte ratio may be served as a predictor and a prognostic risk marker of diabetic nephropathy.

Abstract
The study aimed to revalidate the influence of WBCs on chronic disease risk factors and to verify which markers are independently involved in WBC level changes in a Korean population. A total of 80 Korean subjects were divided into three groups, according to the WBC count: mild decrease in WBC, normal WBC, and mild increase in WBC. Fasting blood samples for analyzing biochemical parameters and inflammatory markers were obtained from the subjects, and their body fat composition was evaluated by dual energy x-ray absorptiometry and computed tomography. The WBC levels were related to levels of adiponectin, triglyceride, and insulin, which are associated with the risk of chronic diseases. In the mild increase in WBC group, high-sensitivity C-reactive protein (hs-CRP) and TNF-α levels increased, and s.c. fat area at the first lumbar vertebrae and fourth lumbar vertebrae decreased. The WBC count positively correlated with hs-CRP and TNF-α levels and most of the body fat composition data, evaluated by dual energy x-ray absorptiometry and computed tomography. Notably, hs-CRP and TNF-α levels, fat mass, and visceral-to-s.c. fat area ratio at the first lumbar vertebrae were revealed as independent predictors of WBC level change. Finally, the receiver operating characteristic curve analysis showed that the additional use of body fat composition data with the conventional inflammatory markers reliably enhanced the predictive capacity of WBC level changes. Thus, we suggest that by controlling inflammatory markers and body fat composition, WBC levels can be kept within a range that is safe from the risk of chronic diseases.

Abstract
Lymphocyte-related blood parameters (LRBP), including neutrophil-lymphocyte ratio (NLR), platelet-lymphocyte ratio, and lymphocyte-monocyte ratio, could reflect a patient's overall inflammatory status. We aimed to clarify the association between preoperative LRBP and outcomes of type B aortic dissection (TBAD) patients undergoing thoracic endovascular aortic repair (TEVAR). A total of 841 patients were enrolled from 2010 to 2017. Twenty-six (3.1%) patients died during hospitalization and 71 (8.7%) patients died after a median follow-up of 47.3 months. Multivariate analyses showed that the NLR was the only independent predictor for in-hospital death (odds ratio, 1.15; 95% confidence interval [CI], 1.09-1.22; P < .001); 4.1 was identified as the optimum threshold for NLR after applying the X-tile program. Propensity score matching (PSM) was performed to diminish bias and yielded 174 matched pairs. Neutrophil-lymphocyte ratio >4.1 was demonstrated to be independently associated with follow-up mortality before (hazard ratio [HR], 2.53; 95% CI, 1.44-4.43; P = .001) and after PSM (HR, 3.11; 95% CI, 1.35-7.15; P = .008). The relationship between LRBP and follow-up reintervention or stroke were not significant (P > .05 for both). Elevated NLR was an independent indicator for in-hospital and follow-up mortality in patients with TBAD undergoing TEVAR; this might provide additional risk stratification.

Abstract
Background: Recently, inflammatory cell ratios have gained importance as useful indicators in the categorization of asthma.Objective: We compared the concentration of white blood cells in peripheral blood, as well as their respective inflammatory cell ratios, between patients with asthma and a healthy control group.Methods: We performed cross-sectional analyses of the data obtained from 53 adult patients with asthma and 109 adult controls. In our study, we estimated and compared the following inflammatory cell ratios: Neutrophil-Lymphocyte Ratio (NLR), Eosinophil-Lymphocyte Ratio (ELR), Eosinophil-Neutrophil Ratio (ENR), Eosinophil-Monocyte Ratio (EMR), and Platelet-Lymphocyte Ratio (PLR). The magnitude of association was quantified with the odds ratio.Results: In both groups, the average age was 33 years. In asthmatic patients, we obtained the following results: eosinophils ≥ 400 cells/µl, accounted for 37.7%; basophils ≥ 110 cells/µl, comprised 37.7%; and monocytes < 320 cells/µl, reached 11.3%. In the control group, the results were as follows: 4.6%, 9.2% and 0.9%, respectively. When compared to the control group, asthmatic patients had higher odds of eosinophils ≥ 400 cells/µl (OR = 12.61, p < 0.0001); higher odds of basophils ≥ 110 cells/µl (OR = 6.00, p < 0.0001); and increased odds of monocytes < 320 cells/µl (OR = 13.79, p = 0.017). NLR did not differ between our two groups; however, ELR, ENR, EMR and PLR were significantly higher in the asthma group.Conclusions: Overall, patients with asthma have a higher concentration of eosinophils and basophils, fewer monocytes in their blood, and higher ratios of increased chronic inflammation.

BACKGROUND Neutrophil-to-lymphocyte ratio (NLR) and the platelet-to-lymphocyte ratio (PLR) have been studied so far as prognostic factors of cardiovascular diseases. Their role interplayed with endothelial inflammation has emerged as optimal predictors for major cardiovascular disease events and prognostic factors for post-procedural outcomes. METHODS A review of the current literature was undertaken to investigate the relationship between NLR and PLR with percutaneous, cardiac surgery, and vascular surgery procedures. RESULTS Our findings show that perioperative NLR and PLR levels are significantly correlated with patient morbidity and mortality rates. CONCLUSION These biomarkers have several attractive characteristics, as they are inexpensive and quickly available, and they can contribute to the early identification of patients at high risk for periprocedural adverse events.

Abstract
BACKGROUND Obesity and its related diseases, type 2 diabetes (T2D) and overall metabolic syndrome, often show a low-grade of chronic inflammation due to loss of balance between pro- and anti-inflammatory signals. Neutrophil-to-lymphocyte ratio (NLR) and platelet-to-lymphocyte ratio (PLR) are considered cost-effective markers for the detection of this subclinical inflammation. OBJECTIVES To evaluate the potential prognostic factor of NLR and PLR as inflammatory biomarkers on weight loss and T2D remission after sleeve gastrectomy (SG). SETTING University Medical Institutions. METHODS Patients who underwent SG as primary treatment for severe obesity were included. Anthropometric and blood parameters were measured at baseline and postoperatively (1, 2, and 5 yr after surgery). The prognostic ability of NLR and PLR was evaluated by a receiver operator characteristic curve and a cutoff point was calculated. A value of P < .05 was considered significant. RESULTS A total of 182 patients were analyzed. Preoperative NLR showed an inverse correlation with excess weight loss (Spearman -.525; P = .033) and units of body mass index lost (Spearman -.502; P = .039) 5 years after surgery. Preoperative NLR also showed a direct correlation with fasting glucose (Spearman .685; P = .002) and Homeostasis Model Assessment of Insulin Resistance (Spearman .764; P < .001). Lower preoperative NLR is also associated with a complete remission of T2D at 5 years. Preoperative PLR did not show any correlation with the variables studied. CONCLUSION The preoperative NLR is a potential prognostic factor of long-term weight loss and T2D remission in patients undergoing SG. PLR does not correlate with metabolic parameters in these patients.
