Abstract Background: This study aimed to explore the differences in the neutrophil-to-lymphocyte ratio (NLR) and platelet-to-lymphocyte ratio (PLR) in patients with neuromyelitis optica spectrum disorders (NMOSDs) as well as their relationship with the onset of the diseases.Methods: The clinical data, laboratory findings, and imaging data of patients with NMOSD admitted to Perking University Third Hospital from January 2015 to December 2020 were retrospectively analyzed. Routine blood tests of patients performed within one week of the appearance of new clinical symptoms or imaging lesions were collected to calculate the NLR and PLR. The routine blood test of the patients in remission was performed more than 6 months after the patients stopped hormone use. The NLR and PLR of patients were compared with those of 100 healthy subjects undergoing physical examinations.Results: A total of 55 patients with NMOSD were enrolled. 44 patients with NMOSD were followed up. In patients with NMOSD, the white blood cell (WBC) count, absolute neutrophil count, and NLR were significantly higher than those in patients in remission and the controls, while the absolute lymphocyte count was significantly lower than that in patients in remission and the controls. In patients with NMOSD in remission, there were no statistically significant differences in the WBC count, absolute neutrophil count, absolute lymphocyte count, or NLR compared with the controls. The PLR of patients with NMOSD in the attack stage was significantly higher than that of the controls, while the PLR of patients with NMOSD in remission was not significantly different from that of the attack stage and the controls. There were no statistically significant differences between APQ4 (+) and APQ4 (-) in patients with NMOSD at the attack stage in the WBC count, absolute neutrophil count, absolute lymphocyte count, platelet count, NLR or PLR. ROC analysis of NLR and PLR for the diagnosis of inflammatory changes in NMOSD at the attack stage and controls: The ROC curve was plotted using NLR and PLR as dependent variables. In patients with NMOSD, the AUC was 0.806 for NLR and 0.612 for PLR. ROC analysis of NLR and PLR for the diagnosis of inflammatory changes in NMOSD at the attack stage and remission stage. The AUC was 0.728 for NLR and 0.594 for PLR.Conclusion: Patients with NMOSD had significantly higher WBC counts, absolute neutrophil counts and NLRs, and elevated NLRs were correlated with inflammatory activity in NMOSD.

In this study, a combination of clinical and hematological information, collected on day of presentation to the hospital with pneumonia, was evaluated for its ability to predict severity and mortality outcomes in COVID-19. Ours is a retrospective, observational study of 203 hospitalized COVID-19 patients. All of them were confirmed RT-PCR positive cases. We used simple hematological parameters (total leukocyte count, absolute neutrophil count, absolute lymphocyte count, neutrophil to lymphocyte ration and platelet to lymphocyte ratio); and a severity classification of pneumonia (mild, moderate and severe) based on a single clinical parameter, the percentage saturation of oxygen at room air, to predict the outcome in these cases. The results show that a high absolute neutrophil count on day of onset of pneumonia symptoms correlated strongly with both severity and survival in COVID-19. In addition, it was the primary driver of an initial high neutrophil-to-lymphocyte ratio (NLR) observed in patients with severe disease. The effect of low lymphocyte count was not found to be very significant in our cohort. Multivariate logistic regression was done using Python 3.7 to assess whether these parameters can adequately predict survival. We found that clinical severity and a high neutrophil count on day of presentation of pneumonia symptoms could predict the outcome with 86% precision. This model is undergoing further evaluation at our centre for validation using data collected during the second wave of COVID-19. We present the relevance of an elevated neutrophil count in COVID-19 pneumonia and review the advances in research which focus on neutrophils as an important effector cell of COVID-19 inflammation.

Background/Aim: To investigate the utility of peripheral blood biomarkers – absolute lymphocyte count (ALC), neutrophil-to-lymphocyte ratio (NLR), and platelet-to-lymphocyte ratio (PLR) – for predicting outcomes in eribulin-treated patients with metastatic human epidermal growth factor receptor type 2 (HER2)-negative breast cancer. Patients and Methods: ALC, NLR, and PLR were retrospectively obtained from pre-treatment blood sampling results of 120 patients and stratified according to means. Univariate and multivariate analyses were performed to investigate the association of clinicopathological factors, including these values, with overall survival (OS) and progression-free survival (PFS). Results: The ALC, NLR, and PLR cut-off points were 1,285/μl, 3.3, and 235, respectively. No biomarkers were associated with PFS. However, univariate analysis showed ALC (p=0.044) and PLR (p=0.044) to be significantly associated with OS. Conclusion: ALC and PLR can predict eribulin efficacy in terms of OS, reflecting the antitumour immune response in the microenvironment and indicating eribulin’s effectiveness.

Background: COVID-19 is an ongoing pandemic caused by virus SARS-CoV-2. Many studies worldwide have documented hematological alterations in COVID-19. The present study also aimed to assess the CBC parameters in COVID-19 patients. Material And Methods: It was an observational study conducted in the Department of Pathology, Govt. Medical College, Jammu. COVID-19 patients admitted in the hospital were included in the study. Demographic details and clinical status were noted. EDTA anticoagulated blood samples received were processed on automated 5-part hematology analyzer for CBC. Various parameters obtained were evaluated and also compared with clinical severity of the patients. Results were tabulated and analysed statistically. Results: The study included 304 hospitalized COVID-19 patients. Males were 219 (72%) and females were 85 (28%). Median 6 age of patients was 55 years. Mean hemoglobin concentration was 12.05 g/dl (SD-1.93), mean RBC count was 4.21x10 /µL (SD3 3 0.69). Mean WBC count was 9.66x10 /µL (SD-4.80), mean absolute neutrophil count was 7.87x10 /µL (SD-4.63), mean absolute 3 3 lymphocyte count was 1.22x10 /µL (SD-0.77), mean absolute monocyte count was 0.52x10 /µL (SD-0.29), mean absolute 3 eosinophil count was 0.04 x10 /µL(SD-0.10). Mean NLR was 10.03 (SD-12.27), mean LMR was 2.84 (SD-2.02), mean PLR was 3 220.16 (SD-208.46). Mean platelet count was 187x10 /µL (SD-97.78). Patients with severe disease show signicantly raised WBC count and absolute neutrophil count, signicantly decreased absolute lymphocyte count, signicantly higher eosinophil count, NLR, PLR and signicantly decreased LMR with no signicant difference in absolute monocyte count and platelet count. Conclusion: Routine monitoring of CBC parameters in COVID – 19 patients during the course of illness is a simple, rapid means to assess disease severity and progression in these patients.

We hypothesized that hemoglobin levels, absolute neutrophil count, and absolute lymphocyte count were associated with radiotherapy response and cancer progression and that they might reflect tumor repopulation during concurrent chemoradiotherapy. This study aimed to investigate these hematological parameters as prognosticators of cervical cancer. We analyzed 105 stage IIB cervical cancer patients treated with concurrent chemoradiotherapy, using log-rank tests and multivariate analyses. Hazard ratios were calculated weekly to evaluate changes in hemoglobin, absolute neutrophil count, and absolute lymphocyte count that were associated with disease-specific survival. Patients were categorized into the high hematological risk (patients with low hemoglobin plus high absolute neutrophil count and/or low absolute lymphocyte count) and the low hematological risk (others) groups according to the median cutoff values. During the second week of concurrent chemoradiotherapy, hematological factors were significantly associated with survival. In multivariate analysis, hematological risk was independently associated with disease-specific survival and progression-free survival. The 5-year disease-specific survival and progression-free survival rates in the high hematological risk group were significantly lower compared with those in the low hematological risk group (81.6% vs 92.6%, p = 0.0297; 73.7% vs 89.3%, p = 0.0163, respectively). During the second week of concurrent chemoradiotherapy, the hematological parameters could predict treatment outcome in stage IIB cervical cancer.
