Poor Outcomes

Background and Purpose: Neutrophil to lymphocyte ratio (NLR) is positively associated with poor prognosis in patients with cerebral infarction. The goal of this prospective study is to explore the predictive value of NLR in patients with acute ischemic stroke (AIS) caused by cervicocranial arterial dissection (CCAD).Methods: Ninety-nine patients with AIS caused by CCAD met criteria for inclusion and exclusion were selected for this study. We collected baseline data on the admission including NLR. The primary poor outcome was major disability (modified Rankin Scale score ≥ 3) or death at 3 months after AIS.Results: A total of 20 (20.2%) patients had a poor outcome at 3 months after AIS. According to the 3-month outcome, the patients were divided into two groups and univariate and multivariable analyses were conducted. Among the risk factors, elevated NLR levels were independently associated with 3-month poor outcomes. Further, we made the ROC curve to evaluate the predictive value of NLR level on prognosis. The area under the curve was 0.79 and a cut-off value of NLR was 2.97 for differentiating the poor outcome. We divided patients into groups according to the cut-off value. Patients with high NLR have a higher risk of poor outcome than those with low NLR (P < 0.05).Conclusion: As an inflammatory marker, elevated NLR levels were associated with 3-month poor outcome in AIS caused by CCAD.

AbstractBy setting out from increased neutrophil count, decreased lymphocyte count, and increased mean platelet volume (MPV), which is a result of the effect of inflammation on blood cells, we aimed to investigate whether neutrophil to lymphocyte ratio (NLP) and MPV can be used as an auxiliary parameter for the diagnosis of early-onset neonatal sepsis (EOS). This study was conducted by analyzing term neonates with EOS and physiological jaundice who were admitted to the neonatal intensive care unit of Izmir Katip Celebi University Ataturk Training and Research Hospital. A total of 63 neonate files were examined to include 30 term neonates with EOS, and 77 neonate files were examined to include 30 term neonates with physiological jaundice as a control group. NLR had an area under the curve (AUC) of 0.891 for prediction of EOS. At a cut-off level of 1.42, NLR had a likelihood ratio (LR) of 5.5, sensitivity of 88%, a specificity of 84%, a positive predictive value (PPV) of 84.6%, and a negative predictive value (NPV) of 87.5%. MPV had an AUC of 0.666 for the prediction of EOS and at a cut-off level of 9.3 fL, MPV had an LR of 1.23, sensitivity of 84%, a specificity of 32%, a PPV of 55.2%, and an NPV of 66.6%. In conclusion, this study provides evidence that NLR and MPV can be used in addition to conventional parameters in the diagnosis of EOS.

Objectives: This study was conducted to evaluate the diagnostic value of platelet-to-lymphocyte ratio (PLR) and neutrophil-to-lymphocyte ratio (NLR) in vaginitis patients. Methods: This cross-sectional retrospective study was performed in Afyon Dinar State Hospital between July 2016 to August 2017. A total of 64 bacterial vaginosis (BV) patients, 66 vulvovaginal candidiasis (VVC) patients and 65 age-matched control subjects were enrolled. NLR, PLR, mean platelet volume (MPV), red cell distribution width (RDW) and other conventional inflammatory marker values were recorded for all patients before and after treatment. Results: In the BV group, NLR values were found to be elevated compared to VVC and healthy controls [2.9 (1.2-14.7), 2.1 (1.1-11.7) and 2.1 (0.8-7.0), respectively] (p=0.008). Although not found to be statistically significant, the median NLR levels of BV patients decreased from 2.9 (1.2-14.7) to 2.4 (1.2-7.0) after treatment. PLR levels did not show a statistically significant difference between the three groups (p=0.970). The cut-off value of the NLR for BV was 2.19, with 67.2% sensitivity and 63.8% specificity. Conclusions: The present study demonstrated that NLR levels are elevated in bacterial vaginosis and NLR levels can be used as a reflection of systemic inflammatory response in vaginosis patients. doi: https://doi.org/10.12669/pjms.37.1.2774 How to cite this:Pek E, Beyazit F, Korkmaz NS.

Background: Hematological indices can predict disease severity, progression, and death in patients with coronavirus disease-19 (COVID-19). Objectives: To study the predictive value of the dynamic changes (first 48 h after ICU admission) of the following ratios: neutrophil-to-lymphocyte (NLR), platelet-to-lymphocyte (PLR), monocyte-to-lymphocyte (MLR), systemic inflammation index (SII), and derived neutrophil-to-lymphocyte (dNLR) for invasive mechanical ventilation (IMV) need and death in critically ill COVID-19 patients. Methods: Observational, retrospective, and multicentric analysis on 272 patients with severe or critical COVID-19 from two tertiary centers. Hematological indices were adjusted for confounders through multivariate analysis using Cox regression. Results: Patients comprised 186 males and 86 females with no difference across groups (p > 0.05). ΔNLR > 2 had the best independent predictive value for IMV need (HR = 5.05 (95% CI, 3.06–8.33, p < 0.0001)), followed by ΔSII > 340 (HR = 3.56, 95% CI 2.21–5.74, p < 0.0001) and ΔdNLR > 1 (HR = 2.61, 95% CI 1.7–4.01, p < 0.0001). Death was also best predicted by an NLR > 11 (HR = 2.25, 95% CI: 1.31–3.86, p = 0.003) followed by dNLR > 6.93 (HR = 1.89, 95% CI: 1.2–2.98, p = 0.005) and SII > 3700 (HR = 1.68, 95% CI: 1.13–2.49, p = 0.01). Conclusions: Dynamic changes of NLR, SII, and dNLR independently predict IMV need and death in critically ill COVID-19 patients.

Background: Henoch–Schonlein purpura (HSP) is one of the commonest entities included within the category of cutaneous vasculitis (CV). Our work is purposed to explore the predictive value of neutrophil-to-lymphocyte ratio (NLR) for systemic involvement in Henoch– Schonlein purpura patients. This ratio is known as an inflammatory marker, and is used to assess the systemic inflammation associated with various diseases. Our objective is to establish whether it can be applied for the prediction of renal and gastrointestinal (GI) or purely renal involvement in Henoch–Schonlein purpura. Aim: To determine the relationship between neutrophil-to-lymphocyte ratio and systemic involvement in Henoch–Schonlein purpura Methods: This is a retrospective review of the patients who were diagnosed with Henoch–Schonlein purpura in our hospital between 2012 and 2018. Results: A total of 57 patients met our inclusion criteria. Pre-treatment neutrophil-to-lymphocyte ratio was significantly associated with renal and/or GI manifestations of the disease (p<0.001). The optimal cut-off value of this ratio for predicting systemic involvement was 2.48, with a 95% specificity and a 94% sensitivity. In addition, pretreatment ratio was also found to be significantly correlated with the severity of relevant systemic manifestations of Henoch–Schonlein purpura (r=0.831; p<0.01). Limitations: The small number of patients recruited for our research, its retrospective design, and the inclusion of patients attending the same hospital. Conclusion: This study suggests that neutrophil-to-lymphocyte ratio is suitable as a potential indicator for predicting the systemic involvement in Henoch–Schonlein purpura.
