接种 COVID-19 疫苗后的绝对淋巴细胞计数与 18F-FDG PET/CT 上疫苗诱导的高代谢淋巴结相关：乳腺癌护理的重点
我们的目的是预测接种 2019 冠状病毒病 (COVID-19) 疫苗后 18 F-FDG PET/CT 上是否存在疫苗诱导的高代谢淋巴结 (v-HLN)，并确定它们与淋巴细胞计数的关系。方法：在这项回顾性单中心研究中，我们纳入了 2021 年 3 月初至 4 月下旬期间接种基于信使 RNA 或病毒载体的 COVID-19 疫苗后接受 18 F-FDG PET/CT 成像的连续患者。收集人口统计学、临床参数和绝对淋巴细胞计数 (ALC)，并通过逻辑回归研究它们与引流区中 v-HLN 存在的关系。结果：总共有 260 名患者符合条件，其中包括 209 名（80%）女性和 145 名（56%）乳腺癌患者。中位年龄为 50 岁（范围为 23 – 96 岁）。 233 人（90%）接种了信使 RNA 疫苗。90 人（35%）患有 v-HLN，SUV 最大值中位数为 3.7（范围：2.0 – 26.3），74 人（44%）出现淋巴细胞减少，ALC 中位数为 1.4 3 10 9 /L（范围：0.3 – 18.3 3 10 9 /L）。多变量分析显示，年龄≤50岁（OR=2.2；95% CI=1.0～4.5）、无淋巴细胞减少（OR=2.2；95% CI=1.1～4.3）及最后一次疫苗注射与18F-FDG PET/CT显像时间间隔小于30天（OR=2.6；95% CI=1.3～5.6）为v-HLN的独立因素。在乳腺癌患者中，无淋巴细胞减少是与v-HLN显著相关的唯一独立因素（OR=2.9；95% CI=1.2～7.4）。结论：接种 COVID-19 疫苗后 ALC 正常的患者在 18 F-FDG PET/CT 上出现 v-HLN 的可能性更大，这两者都可能与疫苗接种后更强的免疫反应有关。

由于淋巴细胞减少症患者的进行性多灶性白细胞症（PML）的风险增加而提高了警惕性，如下所示：严重淋巴细胞减少症患者不应启动富马酸二甲基二甲基二甲基（淋巴细胞计数<0.5 x 10 9 /L）。严重淋巴细胞减少症患者（淋巴细胞计数<0.5 x 10 9 /L）应停用富马酸二甲基。在中度减少绝对淋巴细胞计数≥0.5x 10 9 /L至<0.8 x 10 9 /L的患者中，应重新评估富马酸二甲基二甲基治疗的益处 /风险。在局部实验室参考范围定义的淋巴细胞计数低于正常（LLN）低于正常的淋巴细胞计数的患者中，建议定期监测绝对淋巴细胞计数。可能进一步增加单个PML风险的其他因素应

背景：寻找生物标志物以识别合适的免疫检查点抑制剂（ICI）疗法的候选者。我们评估了下一代免疫检查点淋巴细胞激活基因-3（SLAG-3）的可溶水平，以及其与循环T淋巴细胞亚群的关联可能会构成一种新型的生物标志物，以预测ICI疗法的结果。方法：使用多重免疫测定法分析了n = 84例接受ICI治疗的晚期固体癌症患者的循环水平，并伴随着外周血单核细胞（PBMC）的流量细胞仪分析。RESULTS: Uni- and multivariate analysis shows that patients with higher sLAG3 concentrations before ICI therapy had a signi fi cantly impaired progression-free (PFS) and overall survival (OS) (HR PFS : 1.005 [95%CI: 1.000 – 1.009], p = 0.039; HR OS : 1.006 [95% CI: 1.001 – 1.011], p = 0.015).与具有增加相比的患者相比，基线和1-2个周期之间的比率降低的患者的CD4/CD8细胞比率及其在治疗过程中的动力学是PFS和OS的强烈预测指标（P = 0.012，HR：3.32）。结合Slag3和CD4/CD8比的免疫学评分显示出最高的预测潜力（HR OS：10.3）。结论：未来的前瞻性验证，SLAG3和相关的循环T细胞子集可以用作非侵入性预测标记，以预测ICI疗法的结果，以帮助将来识别理想的ICI候选者。
慢性淋巴细胞白血病：2022 年诊断和治疗程序更新
4. 进行性淋巴细胞增多，2 个月内增多≥50%，或淋巴细胞倍增时间（LDT）小于 6 个月。LDT 可通过在 2-3 个月的观察期内每隔 2 周获得的绝对淋巴细胞计数（ALC）的线性回归外推获得；初始血液淋巴细胞计数<30 000/μL 的患者可能需要更长的观察期来确定 LDT。应排除除慢性淋巴细胞白血病之外的其他导致淋巴细胞增多的因素（例如感染、类固醇给药）
骨细胞EGLN1/PHD2通过FGF23
目的：评估用以下3种治疗方式治疗的食管癌患者的辐射诱导淋巴细胞耗竭的可能差异：强度调节放射治疗（IMRT），被动散射质子治疗（PSPT）和强度调节的蛋白质治疗（IMPT）。方法和材料：我们使用了2个预测模型来估计基于剂量分布的淋巴细胞耗竭。模型我使用了淋巴细胞存活与体素剂量之间的分段线性关系。Model II假定淋巴细胞作为总剂量的函数呈指数耗尽。模型可以使用每周的绝对淋巴细胞计数在整个治疗过程中收集的测量。我们随机选择了45例在我们机构中用IMRT，PSPT或IMPT治疗的食管癌患者（每种模式15），以证明这两种模型的适应性。在多种模态的计算机模拟中纳入了已接受PSPT的10例食管癌患者。使用我们的每种模式的我们的实践标准制定了一个IMRT和一个IMPT计划，作为每个患者现有PSPT计划的竞争计划。我们拟合了用于治疗的PSPT计划的模型，并预测了IMRT和IMPT计划的绝对淋巴细胞计数。结果：对每个患者模式组的模型验证表明，在模态和模型中，测得的和预测的绝对淋巴细胞计数之间的良好一致性，其平均误差为0.003至0.023。结论：质子计划在治疗课程后的预测风险低于光子计划。在对10名PSPT患者的IMRT和IMPT的仿真研究中，预测的绝对淋巴细胞计数（ALC）NADIRS分别在IMRT，PSPT和IMPT治疗后，使用Model I和0.14、0.22，以及0.14、0.22，以及0.22 k/ l L L L LINES II使用模型。此外，IMPT计划在预测的淋巴细胞保存方面优于PSPT。
克雷伯氏菌中抗菌抗性的机制
背景：心力衰竭病理生理学及其临床症状的特征是炎症。升高的白细胞亚群是炎症的众所周知的指标，在确定心血管疾病患者的预后中起着预测作用。此外，血小板是炎症的重要介质，尤其是当它们与白细胞相互作用时。血小板合成，激活和功能都受心力衰竭的影响。因此，该研究旨在确定心力衰竭患者的血小板，中性粒细胞和淋巴细胞异常的大小。方法：从2022年6月至2022年7月在贡达大学综合专业医院进行了回顾性横断面研究。总共包括245例心力衰竭患者的病历。从病历中收集了有关社会人口统计学，临床和一些血液学和生化参数的数据。数据已输入EPI-DATA 4.6.0.2，然后导出到Stata 11.0统计软件进行分析。计算出及其优势比的二元逻辑回归分析，以识别与结果变量相关的因素。p值<0.05被认为具有统计学意义。结果：心力衰竭成年人中最常见的白细胞异常是中性粒细胞，在17.55％（95％CI：13.26–22.87）中被发现。此外，在10.20％（95％CI：6.97–14.70）的患者中观察到淋巴细胞增多。只有女性与心力衰竭患者的嗜中性粒细胞显着相关（AOR = 2.33; 95％CI：1.05–5.16）。心力衰竭患者的血小板减少症和血小板病的大小为12.24％（95％CI：8.67–17.01％）和2.86％（95％CI：1.36-5.90％）。但是，这些变量均未与血小板和淋巴细胞异常显着相关。结论：心力衰竭患者的常见白细胞和血小板异常。因此，对这些异常的基本原因的早期检测和管理对于改善患者的结局并防止进一步的并发症可能很重要。关键词：心力衰竭，血小板，中性粒细胞，淋巴细胞，中性粒细胞，淋巴细胞增多，血小板减少症
艾德拉利西布和皮质类固醇治疗滤泡性淋巴瘤期间发生播散性隐球菌病
摘要 一名因滤泡性淋巴瘤复发而接受艾代拉西布和皮质类固醇治疗的患者，因不明原因发烧来到我们的急诊室。尽管开始使用广谱抗生素和补液，患者的临床状况仍然恶化。最终确诊为播散性隐球菌病，免疫表型分析显示循环 B 和 CD4 + -T 淋巴细胞完全缺失，CD8 + -T 淋巴细胞计数明显减少。在本例中，艾代拉西布和皮质类固醇治疗可能导致严重的淋巴细胞减少，并且是该方案下报告的第一例播散性隐球菌病。停用艾代拉西布和类固醇并开始抗真菌治疗后，淋巴细胞计数部分恢复。临床症状改善后，患者可以出院。本病例强调艾代拉西布和皮质类固醇联合使用可导致严重的免疫功能低下和机会性感染。此外，我们还说明了停用艾德拉利西布和皮质类固醇后淋巴细胞重建的速度。
