SUMMARY OBJECTIVE: Inflammation has been suggested as a potential mechanism in the pathogenesis of arrhythmia. Hemogram parameters such as monocyte count to high-density lipoprotein cholesterol ratio (MHR), neutrophil/lymphocyte ratio (NLR), and monocyte/lymphocyte ratio (MLR) have been considered to be markers of inflammation and new cardiovascular risk predictors. This retrospective study aimed to investigate the relationship between MHR, NLR, and MLR in patients with paroxysmal supraventricular tachycardia (PSVT). METHODS: A retrospective study conducted at a university hospital in Bolu, Turkey, between 2017 and 2019. Our study included 196 patients who underwent electrophysiological study (EPS) due to palpitation or documented PSVT on electrocardiography (ECG). Patients having documented atrioventricular nodal re-entrant tachycardia (AVNRT) on ECG or inducible AVNRT on EPS were included in the PSVT group (n=130), and patients with palpitation but without inducible arrhythmia on EPS (n=66) were included in the control group. Routine biochemical and hemogram tests were performed before the EPS procedure. RESULTS: When hemogram parameters were compared, there was no statistically significant difference in MHR values [0.010 (0.001-0.030) vs 0.010 (0.001-0.020) p =0.67]. Additionally, both NLR [2.21(0.74-11.36) vs 1.98(0.72-24.87) p=0.13] and MLR [0.25 (0.03-1.05) vs 0.24(0.07-1.39) p=0.41] were not statistically significant between the two groups. CONCLUSION: There is no significant difference in PSVT patients regarding hemogram parameters including white blood cell subtypes, MLR, NLR, and MHR. Therefore the evaluation of hemogram parameters may not be clinically relevant for PSVT patients.

AbstractObjectivesTo evaluate the relationship between Coronavirus Disease 2019 (COVID-19) in pregnancy and adverse perinatal outcomes. The secondary aim is to analyze the diagnostic value of hematologic parameters in COVID-19 complicated pregnancies.MethodsThe current study is conducted in a high volume tertiary obstetrics center burdened by COVID-19 pandemics, in Turkey. In this cohort study, perinatal outcomes and complete blood count indices performed at the time of admission of 39 pregnancies (Study group) complicated by COVID-19 were compared with 69 uncomplicated pregnancies (Control group).ResultsThere was no significant difference between the obstetric and neonatal outcomes of pregnancies with COVID-19 compared to data of healthy pregnancies, except the increased C-section rate (p=0.026). Monocyte count, red cell distribution width (RDW), neutrophil/lymphocyte ratio (NLR), and monocyte/lymphocyte ratio (MLR) were significantly increased (p<0.0001, p=0.009, p=0.043, p<0.0001, respectively) whereas the MPV and plateletcrit were significantly decreased (p=0.001, p=0.008) in pregnants with COVID-19. ROC analysis revealed that the optimal cut-off value for MLR was 0.354 which indicated 96.7% specificity and 59.5% sensitivity in diagnosis of pregnant women with COVID-19. A strong positive correlation was found between the MLR and the presence of cough symptom (r=41.4, p=<0.0001).ConclusionsThe study revealed that, pregnancies complicated by COVID-19 is not related with adverse perinatal outcomes. MLR may serve as a supportive diagnostic parameter together with the Reverse Transcriptase Polymerase Chain Reaction (RT-PCR) in assessment of COVID-19 in pregnant cohort.

Abstract Purpose To compare the rates obtained from hematological parameters in cases of late-onset idiopathic fetal growth restriction (FGR) with healthy pregnancies and to evaluate the effect on neonatal outcomes. Methods The study group consisted of 63 pregnant women with late-onset idiopathic FGR and the control group consisted of 91 healthy pregnant women. The determined rates were calculated from the control hemograms of patients at 28 weeks. Both groups were compared for neutrophil/lymphocyte ratio (NLR), platelet/lymphocyte ratio (PLR), and other parameters. Results NLR, leukocyte and neutrophil levels were significantly higher in the FGR group (p<0.05). There was no significant difference in PLR, platelet and lymphocyte levels between the groups (p>0.05). To predict FGR, the best cut-off value of NLR was determined to be 4.11 with 56% sensitivity and 88% specificity values. Conclusion Neutrophil, lymphocyte and platelet interactions have an important role in FGR development. Inflammation can be involved in the etiopathogenesis in late-onset FGR.

Abstract Background Cancer associated inflammation is one of the key determinants of outcome in patients with cancer. An elevated neutrophil: lymphocyte ratio (NLR) has been identified as a predictor of worse survival in patients with various solid tumors compared to hematologic malignancies but no reports yet examined its impact on multiple myeloma. The aim of this study was to examine the prognostic value of an elevated NLR in multiple myeloma. Methods We had approval by our institutional review board to collect the data on patients diagnosed with multiple myeloma at Staten Island University Hospital between year 2000 and 2012 identified from our local cancer database. Data on demographics, conventional prognostic markers, laboratory analyzes including blood count results, and histopathology were collected and analyzed. A cox proportional survival analysis was carried out to assess the relationship between NLR and mortality. NLR was assessed as a continuous variable as well as categorical variable (quartile 0.5-1.5, 1.6-2.2, 2.3-3.8, and 3.9-22.3). Results A total of 96 patients were identified with a median age at diagnosis of 70 (IQR of 61 to 79) years. The median neutrophil count was 3.5 (2.5—5.1) x 10-9/liters, median lymphocyte count 1.5 (1.05-2.4) × 10-9/liters, while the NLR was 2.28 (1.53-3.88). The median overall survival was 147.5 weeks, IQR (88.5-320). NLR did not prove to be a significant predictor of death as a continuous variable (0.95 (0.85-1.06), p =0.35). Furthermore, there was no significant difference in survival with any of the quartiles of NLR. Compare to lowest quartile of NLR, Hazards ratio for the consecutive quartiles were 1.25 (0.56-2.79, p 0.55), 1.36 (0.61-3.04, p=0.45) and 0.89 (0.36-2.22, p=0.80). Conclusion NLR does not appear to offer useful predictive ability for outcome and survival in multiple myeloma patients. Our study is limited with small sample size, further studies are needed to validate our results. Disclosures: No relevant conflicts of interest to declare.

BACKGROUND The infection caused due to novel coronavirus 2 can cause wide spectrum of disease from asymptomatic mild disease to life threatening disease. The widespread inflammation is most likely the cause of the adverse outcomes. There are numerous markers of the inflammation which are used to identify the severity and prognosis of the disease. Neutrophil lymphocyte ratio (NLR) is one such marker which is easily available and feasible in all the hospital settings. This study intended to evaluate the NLR as a marker of disease severity and prognosis, in those with Covid-19. METHODS This was a retrospective study to determine the utility of NLR as a marker of severity and prognosis among patients with Covid disease. Medical records of 60 patients admitted with mild to moderate Covid-19 disease were reviewed and relevant data was retrieved. The NLR at admission and 72 hours later was noted. High resolution computerised tomography was done and computerised tomography severity score (CT-SS) was calculated. The outcomes of these patients were noted. RESULTS Mean NLR at admission in mild disease was 5.6 and in moderate disease was 9.2. This difference was found to be statistically significant. It was also seen that NLR had a positive co-relation with CT severity score, duration of hospital stay, Creactive protein (CRP) and D-dimer. For predicting mortality, NLR with cut off of 6.6 had a sensitivity of 100 % and a specificity of 66.07 %. CRP with cut off of 6.8 had sensitivity of 100 %, specificity of 76.79 %. D-dimer with cut off of 1.6 had specificity of 78.58 %. For predicting severity, NLR with cut off of 6.6 had sensitivity of 75 % and specificity of 80 %. CRP with cut off of 7.9 had sensitivity of 65 % and specificity of 100 %. D-dimer with cut off of 1.3, had sensitivity of 90 % and specificity of 97.5 %. CONCLUSIONS The study shows that neutrophil–lymphocyte ratio is a good indicator of disease severity and has prognostic significance in Covid-19. There is a positive correlation with high-resolution computed tomography (HRCT) chest score and other markers of inflammation among patients with Covid-19. Serial monitoring of NLR can be utilised as a surrogate to HRCT chest to determine disease severity whenever the latter is not available. This can ensure early intervention and help prevent mortality. KEYWORDS Neutrophil-Lymphocyte Ratio, Severity of Covid

Abstract In our study, we aimed to evaluate changes in the neutrophil and lymphocyte series and investigate whether the neutrophil/lymphocyte ratio (NLR) is indicative of inflammations in patients with hyperthyroidism. A total of 161 patients were enrolled, 121 of which had hyperthyroidism (71 Graves’ Disease (GD) and 50 non-Graves hyperthyroidism (NGH) patients) and 40 of which were control group members. Retrospectively, patients’ neutrophil and lymphocyte counts were taken, and the NLR was calculated. While the number of neutrophils was significantly lower in the GD group (p = 0.003), there was no significant difference between the NGH and the control group. In the GD group, NLR values were significantly lower than the other two groups (median 1.39 for GD, median 1.84 for NGH and median 1.83 for the control group, p < 0.001). Only three patients in the GD group had neutropenia. There was also a significant negative correlation between free T3 and neutrophil count and NLR in hyperthyroid patients (r = -0.28, p = 0.001 and r = -0.34, p < 0.001, respectively). In our study, we found that NLR did not in crease in hyperthyroid patients and that this ratio decreased due to the decrease in neutrophil levels in GD. We thus concluded that NLR is not a suitable indicator of hyperthyroidism.

Objectives: This study aims to evaluate the diagnostic and prognostic significance of neutrophil-to-lymphocyte ratio (NLR), platelet-to-lymphocyte ratio (PLR), and lymphocyte-to-monocyte ratio (LMR) values in patients with osteosarcoma. Patients and methods: A total of 172 patients (111 males, 61 females; mean age: 24.3±15.3 years; range, 7 to 82 years) diagnosed with osteosarcoma in our institution between January 2002 and December 2018 were retrospectively analyzed. A total of 165 healthy individuals (115 males, 50 females; mean age: 20.2±9.2 years; range, 10 to 65 years) who did not have infectious, rheumatological or hematological diseases or any pathological finding were assigned as the control group. The clinical, laboratory, and demographic findings of the patients were obtained from hospital records. Pre-treatment NLR, PLR, and LMR values were calculated in all patients. Diagnostic and prognostic values of pre-treatment NLR, PLR and LMR were assessed using receiver operating curve (ROC) analysis. The Kaplan-Meier method was used for survival analysis. Results: For diagnostic approach, the highest significance in area under the curve (AUC) values was obtained for NLR (AUC=0.763). The AUC for PLR and LMR was statistically significant, while the statistical power was weak compared to NLR (AUC=0.681 and 0.603). The NLR, PLR, and LMR were found to be predictors of mortality. The cut-off value was found to be 3.28 for NLR, 128 for PLR, and 4.22 for LMR. The prognostic value of NLR for mortality was higher than (AUC=0.749) PLR (AUC=0.688) and LMR (AUC=0.609). The NLR, PLR, and LMR were associated with overall survival (OS). There was a significant difference in the median OS time among the NLR, PLR, and LMR values (log-rank test order p<0.001, p=0.001, and p=0.004, respectively). Conclusion: Based on our study results, pre-treatment NLR, PLR and MLR have diagnostic and prognostic values in osteosarcoma.

Objective: Testicular cancers, which are less common than other cancers, are important in terms of being seen in young people. Physical examination, imaging, laboratory and tumor markers are used for diagnosis. There are some studies of some blood parameters that can be involved in inflammation and tumorogenesis. We retrospectively compared hematological values measured in our patients who were diagnosed with testicular tumor in comparison with patients with similar age group who underwent varicocelectomy repair. Materials and methods: This cross-sectional retrospective study included 120 patients who underwent radical inguinal orchiectomy for testicular tumor between January 2010 and December 2018, and 171 patients who underwent varicocelectomy as a control group. Patients with an active infection and hematological disorders were excluded from the study. We evaulated hematological parameters including neutrophil (NEU), lymphocyte (LYM), platelet (PLT) count, and mean platelet volume. The study was conducted on 291 patients. divided in two groups: tumor (n = 120) and varicocele (n = 171). Results: There was no statistically significant difference between the groups in terms of PLT / lymphocyte ratio and mean platelet volume (MPV) levels (p > 0.05). The neutrophil /lymphocyte ratio (NLR) of the tumor group was significantly higher than the varicocele group (p = 0.001; p < 0.05). There was a statistically significant difference between the tumor stages in terms of PLT / Lymphocyte ratios (p = 0.006; p < 0.05). Conclusions: There was only a statistically significant increase in NLR values in the testicular tumor group compared to the varicocele group. Larger, randomized controlled studies are needed at this field.

Aims: Acute pancreatitis is a severe inflammation of the pancreas presenting sudden onset with high morbidity and mortality. Simple, accessible, cost-efficient and feasible laboratory tests are still needed to demonstrate the prognosis of the patients. The aim of the present study was to search the efficiency of CRP/Alb ratio as a biochemical marker on mortality and clinical progress in the patients diagnosed with acute pancreatitis in correlation with APACHE-2. Methodology: This prospective case-control study was conducted with the patients diagnosed with acute pancreatitis through Atlanta criteria and healthy volunteers as a control group in the emergency department. Demographic characteristics, vital signs, ultrasound reports, clinical outcomes, neutrophil, lymphocyte, neutrophil/lymphocyte ratio (NLR), CRP, albumin and CRP/Alb ratio, APACHE-2 score within control and patient groups were recorded. Logistic regression analysis was performed to distinguish healthy volunteers from acute pancreatitis cases. Results: There was a statistically significant difference between CRP/Albumin and NLR measurements according to the groups and we found that the measurements of the patient group were significantly higher than the control group. The cut-off point for CRP/Albumin and NLR was found to be respectively 1.08, 4.04 and above. (Respectively; sen: 76.64%, 78.50%; spe: 97.20%, 97.20%; PPV: 96.47%, 96.55%; NPV: 80.62%, 81.89%; the accuracy: 86.92%, 87.85%). APACHE-2 scores ranged from 0 to 16, with a mean of 5.80±3.92. The probability of acute pancreatitis was significantly higher in patients with high CRP/Albumin and NLR. Conclusion: This study showed that CRP/Alb ratio and NLR were positively correlated with APACHE-2 scores that designed for prognosis in patients with acute pancreatitis.
