The neutrophil to lymphocyte ratio (NLR)is an emerging biomarker used in the prognosis of many conditions. We aimed to conduct a meta-analysis to assess the prognostic accuracy of the NLR in determining mortality in patients with Community acquired pneumonia (CAP). The Pubmed, EBSCO, and Scopus databases were searched to find all relevant articles. 10 articles with 5220 patients were included. The pooled area under the curve (AUC) of NLR admission levels to predict 30-Day mortality of CAP patients was 0.706; 95% CI (0.631 to 0.781), while the pooled AUC of NLR levels taken at 3-5 days was 0.882; 95% CI (0.818 to 0.945). Meta analysis also showed a significant difference in the NLR between the Survivors and 30-Day non-survivors. This difference was greater when NLR levels were taken at 3-5 days; Standardized mean difference (SMD) = 1.646; 95% CI (0.451 to 2.840) compared to NLR levels at admission SMD = 1.139; 95% CI (0.514 to 1.764). These results show that the NLR has potential to be incorporated in the routine assessment and stratification of CAP patients, especially in the early-stage evolution (3-5 days), keeping in mind the availability and cost effectiveness of this test.

All Cause Mortality

The aim of this study was to investigate the utility of the neutrophil-to-lymphocyte ratio (NLR) and platelet-to-lymphocyte ratio (PLR) to predict all-cause mortality in patients presenting with acute pulmonary embolism (PE). Three hundred consecutive patients with acute PE between March 2016 and December 2018 were retrospectively analyzed. We identified 191 patients who met the study inclusion criteria. Twenty-eight patients died during the study period. There was a significant difference in PLR, but not NLR, between patients with low risk, submassive, and massive risk PE ( P = .02 and P = .58, respectively, by the Kruskal-Wallis test). Elevated NLR and PLR were associated with all-cause mortality ( P < .01 and P < .01, respectively). Neutrophil-to-lymphocyte ratio of 5.46 was associated with all-cause mortality with sensitivity of 75.0% and specificity of 66.9% (area under the curve [AUC]: 0.692 [95% confidence interval, CI]: 0.568-0.816); P < .01). Platelet-to-lymphocyte ratio of 256.6 was associated with all-cause mortality with sensitivity of 53.6% and specificity of 82.2% (AUC: 0.693 [95% CI: 0.580-0.805]; P < .01). Neutrophil-to-lymphocyte ratio and PLR are simple biomarkers that are readily available from routine laboratory values and may be useful components of PE risk prediction models.

Severe Community Acquired Pneumonia

Mortality of renal transplant recipients with severe community-acquired pneumonia (CAP) remains high, despite advances in critical care management. There is still a lack of biomarkers for predicting prognosis of these patients. The present study aimed to investigate the association between neutrophil-to-lymphocyte ratio (NLR) and mortality in renal transplant recipients with severe CAP. A total of 111 renal transplant recipients with severe CAP admitted to the intensive care unit (ICU) were screened for eligibility between 1 January 2009 and 30 November 2018. Patient characteristics and laboratory test results at ICU admission were retrospectively collected. There were 18 non-survivors (22.2%) among 81 patients with severe CAP who were finally included. Non-survivors had a higher NLR level than survivors (26.8 vs. 12.3, p < 0.001). NLR had the greatest power to predict mortality as suggested by area under the curve (0.88 ± 0.04; p < 0.0001) compared to platelet-to-lymphocyte ratio (0.75 ± 0.06; p < 0.01), pneumonia severity index (0.65 ± 0.08; p = 0.05), CURB-65 (0.65 ± 0.08; p = 0.05), and neutrophil count (0.68 ± 0.07; p < 0.01). Multivariate logistic regression models revealed that NLR was associated with hospital and ICU mortality in renal transplant recipients with severe CAP. NLR levels were independently associated with mortality and may be a useful biomarker for predicting poor outcome in renal transplant recipients with severe CAP.

Background: The neutrophil to lymphocyte ratio (NLR) and the monocyte to lymphocyte ratio (MLR) are two systemic inflammatory indices with promising prognostic and predictive abilities for HDP. The study aimed to determine the abilities of the NLR and MLR in predicting HDP among pregnant women in Ghana. Methods: This was a case-control study that was carried out between September 2015 and May 2016 at the Bolgatanga regional hospital. The study involved 50 pregnant women of whom 60% (30/50) had normotensive pregnancies (controls) and 40% (20/50) were confirmed to have HDP (cases). The cases were compared with the controls in terms of their socio-demographic characteristics, full blood count parameters, NLR and MLR. Probability value <0.05 was considered statistically significant. Results: The chances of developing HDP is more likely when lymphocyte count is increased [OR:1.126(95%CI:1.028-1.233)] but less likely with increased NLR [OR: 0.776(95%CI:0.651-0.926)] and MLR [OR: 0.039(95%CI: 0.003-0.469)]. There was no significant difference in the area under the curve (AUC) between NLR and MLR (0.77 vs 0.76, p>0.05). The sensitivities of NLR and MLR were 95.0% and 70.0%, while their specificities were 56.7% and 73.3%, respectively. The positive likelihood ratio (+LR) of MLR was higher than that of NLR (2.6 vs. 2.2). Conclusion: Both the NLR and MLR have moderate predictive ability for hypertensive diseases of pregnancy (HDP). However, the MLR will be a better predictor for HDP than the NLR. We recommend the addition of NLR and MLR when reporting full blood count results for pregnant women.

AbstractThis updated meta-analysis sought to explore whether pretreatment neutrophil-to-lymphocyte ratio (NLR) could serve as an independent predictor for survival outcomes in patients with cervical cancer. We searched PubMed, Embase, Web of science and Scopus for studies on the association of pretreatment serum NLR with overall survival (OS) and progression-free survival (PFS) among patients with cervical cancer. Included studies with a hazard ratio (HR) and 95% confidence interval (CI) or a p-value were weighted by generic inverse-variance and pooled in a random effects meta-analysis. Subgroup analyses were conducted according to regions, NLR cut-off values and treatments. Publication bias was analyzed by Egger’s and Begg’s tests. A total of 14 studies comprising 6041 patients were included. The median cut-off value for NLR was 2.46 (range from 1.60 to 3.80). The higher NLR was associated to worse OS (HR 1.86, 95% CI 1.44–2.40) and PFS (HR 1.67, 95% CI 1.25–2.23), compared with lower NLR. This association still exited when analyzed according to regions, NLR cut-off values. Moreover, Significant association between NLR and OS was observed in studies which included patients with early stage disease and receiving radical surgeries. High NLR is independently associated with decreased OS and PFS in patients with cervical cancer. Pretreatment NLR is of independent value to predict the survival outcomes in patients with cervical cancer, regardless of regions and primary treatments.

Abstract Objectives A tension headache is the most common type of headache, and its causes are multifactorial. A relationship has been shown between migraine headaches and neutrophil-to-lymphocyte ratio (NLR), platelet-to-lymphocyte ratio (PLR), and C-reactive protein (CRP). In this study, we investigated the NLR, PLR, and serum CRP levels in frequent episodic tension-type headache (FETTH) and chronic tension-type headache (CTTH) patients. Materials and Methods This retrospective study included 64 patients with FETTH, 80 patients with CTTH, and 60 healthy controls who were followed up in the neurology clinic. Hematological parameters were compared between the patient and control groups. Results In CTTH patients, platelets, NLR, PLR, and CRP values were statistically higher than in FETTH patients and patients in the control group. In FETTH patients, the PLR value was higher than in patients in the control group, but there was no statistically significant difference in NLR and CRP values between FETTH patients and patients in the control group. Also, there was no correlation between these values and age and gender. Conclusion Increase platelet count might have an effect on tension-type headache pathophysiology. Systemic inflammation parameters were shown to be significantly higher in CTTH patients. More comprehensive studies are needed to evaluate the effect of systemic inflammation on the chronicity of tension headaches.

A systematic review and meta analysis has been undertaken in order to evaluate the effectiveness of adjuvant therapy following surgery for early ovarian cancer. Trials reported since 1990 have been of a higher quality enabling a meta analysis of adjuvant chemotherapy vs adjuvant radiotherapy and a meta analysis of adjuvant chemotherapy vs observation. There was no significant difference between radiotherapy and chemotherapy, though these comprised studies which demonstrated considerable heterogeneity. Chemotherapy did confer significant benefit over observation in terms of both overall and disease free survival. Except for women in whom adequate surgical staging has revealed well differentiated disease confined to one or both ovaries with intact capsule, platinum chemotherapy should be offered to reduce risk of recurrence.

We reanalyzed previous data to develop a more simplified decision tree model as a screening tool for unrecognized diabetes, using basic information in Beijing community health records. Then, the model was validated in another rural town. Only three non-laboratory-based risk factors (age, BMI, and presence of hypertension) with fewer branches were used in the new model. The sensitivity, specificity, positive predictive value, negative predictive value, and area under the curve (AUC) for detecting diabetes were calculated. The AUC values in internal and external validation groups were 0.708 and 0.629, respectively. Subjects with high risk of diabetes had significantly higher HOMA-IR, but no significant difference in HOMA-B was observed. This simple tool will help general practitioners and residents assess the risk of diabetes quickly and easily. This study also validates the strong associations of insulin resistance and early stage of diabetes, suggesting that more attention should be paid to the current model in rural Chinese adult populations.
