Background and Objectives: Neutrophil-to-lymphocyte ratio (NLR), platelet-to-lymphocyte ratio (PLR), mean platelet volume (MPV), and other components of the routine complete blood count (CBC) were found to be sensitive biomarkers of preeclampsia and other inflammatory obstetric conditions in previous studies, with conflicting results. We speculated that the same associations existed with hemolysis, elevated liver enzymes, and low platelets (HELLP) syndrome in the first trimester of pregnancy. Materials and Methods: We conducted a retrospective case–control study at a tertiary care hospital in NY (USA), in the time frame between January 2016 and December 2018. Our population consisted of pregnant women in the first trimester: We compared patients with HELLP syndrome (cases) with healthy patients (controls) matched by age, body mass index (BMI), parity, and race. Patients with preeclampsia, infection, and fever were excluded. Venous blood samples were obtained as part of the routine work-up during the first prenatal visit in the first trimester, which includes a CBC. The main outcomes were NLR and PLR, and the secondary outcomes were hemoglobin, RDW, platelet count, MPV, neutrophils, and lymphocytes. Results: There were 10 patients in each group. There were no differences in NLR and PLR levels and other CBC components between the two groups. Conclusions: In our study NLR, PLR, and other CBC components did not predict HELLP syndrome. We speculate that HELLP syndrome has a sudden increase of tissue inflammation in the third trimester that is not manifested during the early phases of placentation. Larger studies are needed to evaluate the true ability of NLR, PLR, and CBC components to predict HELLP syndrome in the first trimester.

Abstract Context Due to the wide spectrum of clinical illness in coronavirus disease 2019 (COVID-19) patients, it is important to stratify patients into severe and nonsevere categories. Neutrophil-to-lymphocyte ratio (NLR) and platelet-to-lymphocyte ratio (PLR) have been evaluated rapidly by a few studies worldwide for its association with severe disease, but practically none have been conducted in the Indian population. This study was undertaken to examine the role of NLR and PLR in predicting severe disease in Indian patients. Objectives The objective was to study the association of NLR and PLR observed at the time of admission with maximum disease severity during hospitalization and to study their role in predicting disease severity. Material and Methods A total of 229 COVID-19 patients were admitted at the center during the study period. After applying inclusion and exclusion criteria, 191 patients were included in the study. The demographic, clinical, and laboratory (complete blood count, NLR, and PLR) data of all patients were obtained at the time of admission. Maximum disease severity of all patients was assessed during hospitalization. Statistical Analysis Chi-square and Mann–Whitney U tests were used to assess statistical significance. Receiver operating characteristic curve (ROC) was plotted for NLR and PLR to estimate the cutoff values and sensitivity and specificity using Youden’s index for predicting severe disease. Logistic regression analysis was used to estimate the odds ratios (OR) and 95% confidence intervals. Results Mean NLR and PLR were significantly higher in severe patients (NLR = 7.41; PLR = 204) compared with nonsevere patients (NLR = 3.30; PLR = 121). ROC analysis showed that NLR, in comparison to PLR, had a higher area under the curve (AUC) of 0.779, with a larger OR of 1.237 and cutoff of 4.1, and showed 69% sensitivity and 78% specificity in predicting severe disease. Cut off for PLR was 115.3, which showed 79% sensitivity and 62% specificity in predicting severe disease. Conclusion NLR and PLR, both showing acceptable AUCs, can be used as screening tools to predict disease severity. However, NLR was a better predictor of disease severity.

Purpose: To compare the strength of the relationship between the neutrophil-to-lymphocyte ratio (NLR) and platelet-to-lymphocyte ratio(PLR) results of patients with or without open globe injury (perforation and penetration) in the acute period of orbital trauma. Materials and Methods: Forty patients with open globe injuryand twenty-five patients without open globe injury in the acute period of orbital trauma were enrolled in this retrospective study. Complete blood count measurement results of all subjects were assessed. Results: There was a significant difference in neutrophil-to-lymphocyte ratio and the platelet-to-lymphocyte ratio between orbital trauma with open globe injury group and without open globe injury group (p=0.001, p=0.006). Conclusion: Our results of the blood count measurements suggest that the NLR and PLR at first three hours may predict ocular perforation/penetration and the clinicians have to alert are a risk factor of open globe injury.

e17050 Background: The role of Neutrophil to Lymphocyte Ratio (NLR) and Platelet to Lymphocyte Ratio (PLR) in prognostication of MIBC is not clearly understood. There is growing evidence that, as markers of inflammation, they may have prognostic utility in MIBC at radical cystectomy (RC). Methods: We performed a retrospective analysis of MIBC patients who underwent RC at the Cleveland Clinic from 2/2015 to 1/2018. 84 patients were identified who were either diagnosed with TaN0M0 treated with Neoadjuvant Chemotherapy (NAC) or T1-T4N0M0 disease treated with or without NAC. For NAC, 27 patients received gemcitabine and cisplatin, 2 patients received gemcitabine and carboplatin, 4 patients received unknown regimen, and 3 patients received MVAC. Of the patients, there were 1 with Ta, 34 with T1, 44 with T2, 1 with T3 and 4 with T4 disease. Complete Blood Count with Differential closest to or on the day of resection was used. NLR and PLR were calculated by dividing Absolute Neutrophil Count and Platelet Count by the Absolute Lymphocyte Count, respectively. PLR and NLR were dichotomized at the median. Outcomes were analyzed via Kruskal-Wallis test. Results: Median follow up of patients was 28.8 months. Median NLR and PLR were 15.7 and 263, respectively. Mean NLR and PLR were 18.9 and 310, respectively. NLR and PLR did not correlate with overall survival, recurrence free survival, T or N stage post resection, or pathological response. Females were found to have a higher NLR than males. Conclusions: Contrary to previous reports, our study did not find any prognostic value of NLR and PLR in MIBC patients at RC. Further evaluation of PLR and NLR in MIBC and correlation with molecular features may help understand its potential prognostic role in patients undergoing surgical resection.

Background and objective: Neutrophil-to-lymphocyte ratio (NLR) and platelet-to-lymphocyte ratio (PLR) are new readily available inflammatory markers that have been analyzed in pregnancy-induced hypertensive disorders such as preeclampsia. Studies on the NLR/PLR ratio in hemolysis, elevated liver enzymes, low-platelet count (HELLP) syndrome are limited in the current literature. We compared NLR/PLR and other complete blood count (CBC) components between women with HELLP syndrome and women with healthy pregnancies. Methods: We conducted a retrospective matched case–control study at a tertiary care hospital in NY (USA) in the time frame between January 2016 and December 2018. The study compared pregnant women with HELLP syndrome (cases) to women with healthy pregnancies in the third trimester (controls), matched by age, body mass index (BMI), parity, and race. Patient with preeclampsia, infection, and fever were excluded. Venous blood samples were obtained as part of the routine work-up at admission for delivery, which included a CBC. The main outcomes were NLR and PLR. The secondary outcomes were hemoglobin, red cell distribution width (RDW), platelet count, mean platelet volume (MPV), neutrophils, lymphocytes. Results: There were 14 patients in each group. They were matched by age, race, BMI, and parity. NLR (5.8 vs. 3.6, p-value = 0.002) and neutrophil count (10.7 vs. 6.8, p-value = 0.001) were higher in women with HELLP compared to controls. PLR (34 vs. 130.2, p-value < 0.001) and platelet count (71 vs. 223, p-value < 0.001) were lower in the study group compared to controls. Conclusions: NLR was higher, and PLR was lower in women with HELLP syndrome. These inflammatory markers can be incorporated into the diagnostic algorithm for HELLP syndrome. Future studies are needed to evaluate their ability to predict HELLP syndrome.

Polytomous Logistic Regression

The aim of the study was to retrospectively assess complete blood count (CBC) indices of dogs with periodontitis (PD; n = 73) and dogs with oropharyngeal tumors (OT; n = 92) in comparison to CBC indices of healthy dogs (HD; n = 71). Neutrophil to lymphocyte ratio (NLR), platelet to lymphocyte ratio, mean platelet volume to platelet ratio, and platelet large cell ratio index (PLCRi) were evaluated as biomarkers of systemic inflammatory response provoked by PD and OT. Results of multivariable polytomous logistic regression analysis indicated no significant associations between CBC indices and PD. Both NLR and PLCRi were significantly higher in dogs with OT when compared to HD and dogs with PD and could, therefore, indicate a tumor-associated systemic inflammatory response. Additional studies of CBC indices, along with other biomarkers of systemic inflammatory response, are recommended to validate them as reliable indicators of clinical disease activity.

Abstract Background: It is difficult to predict the complications and prognosis of ECMO, which is gaining widespread use in patients with pediatric surgery. Platelet-to-lymphocyte ratio (PLR) and neutrophil-to-lymphocyte ratio (NLR) are emerging inflammatory markers that can be calculated from complete blood count, which is a cheap and easily accessible laboratory analysis. The ratios between cellular elements in peripheral blood have been demonstrated to provide information on inflammation, infection, and immune response. Methods: Sixty-seven patients who needed ECMO application after undergoing pediatric cardiovascular surgery in our clinic, between May 2005 and April 2020, were included in this study. The age of patients varied between 4 days and 17 years with a mean of 30.59 ± 147.26 months. Results: The relationships between PLR or NLR values and various blood parameters and blood gas results were found to be statistically nonsignificant in our group of pediatric ECMO recipients. Even if the effect of PLR and NLR values on mortality and prognosis is statistically nonsignificant in patients who need ECMO after congenital heart surgery, PLR and NLR are typically elevated in the postoperative period. An increase in these values above a certain threshold may be a statistically significant indicator for the prediction of mortality. Conclusions: There are few studies in the literature concerning PLR and NLR values in patients with pediatric heart surgery. We consider this study will make way for new studies in the future.

Abstract Background: Patients with sickle cell disease (SCD) are at increased risk of developing serious infections as a result of functional asplenia and altered humoral immunity. Nevertheless, presenting symptoms of sepsis such as fever and arthralgias are common in SCD and can occur with many sickle cell related conditions, including vaso-occlussive crises (VOC) and may not correlate with true infections. The neutrophil-to-lymphocyte ratio (NLR) is calculated as the absolute neutrophil count divided by the absolute lymphocyte count and represents an easily accessible value that has been found to correlate with inflammation and prognosis in several conditions. Few studies have evaluated NLR as a biomarker in sickle cell disease, and its utility in differentiating infection vs. VOC in patients presenting to the emergency room remains unknown. Method: We conducted a retrospective review of 143 patients with SCD who presented to the emergency department with fever and painful crises. The patients were divided into two categories based on discharge diagnoses - patients with VOC only (n=92) and patients with proven/possible infection (n=51). Inclusion criteria for both groups were patients with SCD, 17 years and older and complete blood count with differential on presentation; patients who had received antibiotics prior to presentation were excluded. Data collected on presentation included genotype, age, gender, complete blood count, hydroxyurea use. Data was analyzed between the two groups using descriptive statistics and receiver-operating characteristic (ROC) curve analysis. Results: Demographics and clinical characteristics are summarized in the Table. The sample included primarily young adult males with 61% on hydroxyurea. Genotype HbSS (73%) was most prevalent followed by HbSC (23%) and HbSβ (4%). The mean Hb was around 8 g/dL. The VOC group had a lower mean white blood cell (WBC) count of 13.6, compare to 17.2 for patients with proven/possible infection. ROC analysis showed that NLR did correlate with infection, with a modest AUC 0.7 [95% CI (0.59-0.77)] that was significant (p=0.0002) when compared to the AUC=0.5 model. Maximum specificity and sensitivity in this sample was achieved with NLR = 4.5 (Specificity 75% and Sensitivity 59%). Conclusion: In this sample, NLR on presentation significantly but only modestly correlated with infection as opposed to VOC. Optimal performance at NLR=4.5 achieved Specificity 75% and Sensitivity 59%. Despite modest performance, given the widespread availability and cost-effectiveness of NLR testing, further study in a larger sample may derive other variables that can combine with NLR to formulate a predictive model to improve care for these patients.
