Abstract

:Several studies have been conducted to determine the relationship between post-treatment total lymphocyte count (TLC) and overall survival (OS) in patients with malignant tumors including glioblastomas (GBMs). In this retrospective study, whether patients with newly diagnosed GBM experience significant lymphopenia after concomitant chemoradiation (CCRT) was evaluated, and whether TLC after this treatment is associated with OS in the treated population was examined. Using electronic medical records, all patients newly diagnosed with GBM between 2008 and 2016 at Seoul St. Mary's Hospital were retrospectively examined. The eligible criteria included the following: 1) craniotomy with surgical resection or biopsy, 2) completion of CCRT, 3) accessible baseline and/or follow-up complete blood count (CBC). Median TLC significantly decreased after completion of CCRT, compared to TLC at baseline (1742 versus 1319 cells/mm3, P-value < 0.001). Patients with TLC < 1200 cells/mm3 at 4 weeks after the completion of CCRT showed shorter survival than those with TLC ≥ 1200 cells/mm3 with median OS of 14.5 versus 21.0 months (P-value = 0.017). Also, in multivariate analysis for OS, TLC < 1200 cells/mm3 at 4 weeks after the completion of CCRT (HR 1.97, 95% CI 1.61 - 2.25, P-value = 0.004) were significantly associated with shorter survival. The results from the present study indicate that treatment-related total lymphocyte counts after CCRT is associated with worse survival in patients with newly diagnosed GBM.

摘要

: 已经进行了几项研究以确定恶性肿瘤患者 (包括胶质母细胞瘤 (GBMs)) 治疗后总淋巴细胞计数 (TLC) 和总生存期 (OS) 之间的关系。在这项回顾性研究中,评估了新诊断的GBM患者在同步放化疗 (CCRT) 后是否出现显著的淋巴细胞减少,以及治疗后的TLC是否与治疗人群中的OS相关。使用电子病历,对首尔圣玛丽医院2008年至2016年间新诊断为GBM的所有患者进行回顾性检查。合格标准包括以下内容: 1) 开颅手术切除或活检,2) 完成CCRT,3) 可获得的基线和/或随访全血细胞计数 (CBC)。与基线时的TLC相比,CCRT完成后,中值TLC显著降低 (1742对1319个细胞/mm3,P-值   <0.001)。CCRT完成后4周时,tlc <1200个细胞/mm3的患者比tlc ≥ 1200个细胞/mm3的患者生存期更短,中位OS为14.5个月vs 21.0个月 (p值 = 0.017)。此外,在OS的多变量分析中,CCRT完成后4周时tlc <1200细胞/mm3 (HR 1.97,95% CI 1.61-2.25,p值 = 0.004) 与生存期缩短显著相关。本研究的结果表明,CCRT后治疗相关的总淋巴细胞计数与新诊断的GBM患者的生存较差相关。

METHODS:PURPOSE:Following US military implementation of a cold-stored whole blood program, several US trauma centers have begun incorporating uncrossmatched, group O cold-stored whole blood into civilian trauma resuscitation. We set out to evaluate the safety profile, transfusion reactions events, and impact of low-titer group O whole blood (LTO-WB) at our center. METHODS:In November 2017, we added LTO-WB to each of our helicopters and to our emergency department (ED) refrigerator, alongside that of existing red blood cells and plasma. We collected information on all patients with trauma receiving prehospital or ED transfusion of uncrossed, emergency release blood products between November 2017 and June 2018. Patients were divided into those receiving any LTO-WB and those receiving only red blood cell and or plasma (COMP). Serial hemolysis panels were obtained at 3 hours, 24 hours, and 48 hours. All data were run using STATA 12.1. Statistical significance was set at p < 0.05. RESULTS:One hundred ninety-eight patients received LTO-WB and 152 patients received COMP. There were no differences in age, sex, or mechanism. The LTO-WB patients had higher chest Abbreviated Injury Scale scores (median, 3 vs. 2; p = 0.027), as well as worse arrival base excess (median, -7 vs. -5; p = 0.014) and lactate (5.1 vs. 3.5; p < 0.001). The LTO-WB patients received less post-ED blood products than the COMP patients (median, 0 vs. 3; p = 0.001). There was no difference in survival (LTO-WB, 73%; COMP, 74%; p = 0.805). There were only two suspected transfusion reactions, both in the COMP group (p = 0.061). There was no difference in hemolysis panel values. Controlling for age, severity of injury, and prehospital physiology, LTO-WB was associated with a 53% reduction in post-ED blood product transfusion (odds ratio, 0.47; 0.23-0.94 95% CI; p = 0.033) and two-fold increase in likelihood of survival (odds ratio, 2.19; 1.01-4.76 95% CI; p = 0.047). CONCLUSION:Low-titer group O whole blood has similar evidence of laboratory hemolysis, similar transfusion reaction rates, and is associated with a reduction in post-ED transfusions and increase likelihood of survival. LEVEL OF EVIDENCE:Therapeutic, Level II.

METHODS:BACKGROUND:An enhanced inflammatory response is a trigger to the production of blood macromolecules involved in abnormally high levels of erythrocyte aggregation. OBJECTIVE:This study aimed at demonstrating for the first time the clinical feasibility of a non-invasive ultrasound-based erythrocyte aggregation quantitative measurement method for potential application in critical care medicine. METHODS:Erythrocyte aggregation was evaluated using modeling of the backscatter coefficient with the Structure Factor Size and Attenuation Estimator (SFSAE). SFSAE spectral parameters W (packing factor) and D (mean aggregate diameter) were measured within the antebrachial vein of the forearm and tibial vein of the leg in 50 healthy participants at natural flow and reduced flow controlled by a pressurized bracelet. Blood samples were also collected to measure erythrocyte aggregation ex vivo with an erythroaggregometer (parameter S10). RESULTS:W and Din vivo measurements were positively correlated with the ex vivoS10 index for both measurement sites and shear rates (correlations between 0.35-0.81, p < 0.05). Measurement at low shear rate was found to increase the sensitivity and reliability of this non-invasive measurement method. CONCLUSIONS:We behold that the SFSAE method presents systemic measures of the erythrocyte aggregation level, since results on upper and lower limbs were highly correlated.

METHODS:BACKGROUND:Incomplete reversal with a recommended 5-g dose of idarucizumab has been reported in patients with excessively high dabigatran concentrations. A timely detection of reversal failure after idarucizumab using whole blood (WB) coagulation testing is clinically useful. The aims of this study were to determine residual dabigatran activity after idarucizumab on thrombin generation (TG) using in vitro supratherapeutic dabigatran models and to compare 4 WB point-of-care tests (activated partial thromboplastin time [aPTT], prothrombin time [PT], and 2 thromboelastometry tests) with the TG results. METHODS:Blood samples from 12 healthy volunteers were spiked in vitro with 0-5000 ng/mL of dabigatran. Dabigatran reversal was evaluated by adding 1000 μg/mL of idarucizumab (Praxbind) to dabigatran-spiked samples, which reflect the administration of 5-g idarucizumab to a 70-kg patient. Residual dabigatran activity was assessed using the calibrated automated TG (Thrombinoscope) in platelet-poor plasma samples. The TG results were compared with WB aPTT (DRIHEMATO APTT-S) and PT (DRIHEMATO PT-S) using CG02N analyzer, thromboelastometry (ROTEM) triggered by ellagic acid (INTEM) and tissue factor (EXTEM). RESULTS:At a therapeutic concentration of dabigatran (200 ng/mL), the lag time was prolonged, and peak TG was decreased. The effects of dabigatran on TG were increased up to 1000 ng/mL, and TG was obliterated at higher supratherapeutic dabigatran levels (P < .001 versus control, respectively). TG was fully restored with idarucizumab when dabigatran was ≤2000 ng/mL, but residual anticoagulant activity was observed at higher dabigatran levels. Dabigatran prolonged WB aPTT and PT concentration dependently, and residual prolongations were observed when idarucizumab was added to 3000 or 5000 ng/mL of dabigatran (P < .001 versus control, respectively). In contrast, both INTEM and EXTEM clotting times were reversed toward reference ranges at all dabigatran concentrations when idarucizumab was added. CONCLUSIONS:Our data indicate that the recommended dose of idarucizumab may not restore TG completely with excessively elevated concentrations of dabigatran. All WB measurements with aPTT, PT, and thromboelastometry predicted supratherapeutic dabigatran concentrations, whereas those tests varied in sensitivity to residual anticoagulant activity after reversal. WB aPTT corresponded well with plasma TG changes among those measurements, but the use of thromboelastometry may overestimate the effect of idarucizumab. Caution should be exercised before extrapolating in vitro point-of-care data to the clinical monitoring of dabigatran reversal.
