Lancet:托珠单抗可明显改善住院治疗的合并低氧和系统性炎症的新冠肺炎患者的预后

2021-05-04 Nebula MedSci原创

对于住院治疗的伴有低氧和系统性炎症的新冠肺炎患者,托珠单抗治疗可提高其存活率和其他临床预后

大部分新冠肺炎病毒(SARS-CoV-2)感染者无明显症状或只表现出轻度的异常。但是,相当一部分感染者会发展成需要住院治疗的呼吸道疾病,甚至会进展成需要通气支持的严重呼吸衰竭。

本研究旨在评估住院治疗的伴有缺氧和全身性炎症的新冠肺炎(COVID-19)患者采用托珠单抗(tocilizumab)治疗的效果。

这是一项在英国开展的随机、对照、开放标签的平台试验,纳入了低氧(无吸氧时氧饱和度<92%或需要氧疗)、系统性炎症(C反应蛋白≥75 mg/L)的COVID-19患者,随机(1:1)分至两组,只接受标准治疗或标准治疗联合托珠单抗(400-800 mg)治疗。主要终点是28天时的死亡率。

2020年4月23日-2021年1月24日,RECOVERY试验招募的21550位患者中有4116位成年患者被纳入托珠单抗的评估,包括3385位(82%)接受了系统性皮质类固醇治疗的患者。

两组28天内的死亡率和出院率

总体上,2022位患者被分至托珠单抗组,2094位被分至常规治疗组。在28天内,托珠单抗组和常规治疗组分别有621位(31%)和729位(35%)患者死亡(发生率比 0.85,95% CI 0.76-0.94)。在所有预先指定的患者亚组分析中均观察到了一致的结果,包括那些接受全身性皮质类固醇激素治疗的患者。

托珠单抗组的患者更可能在29天内顺利出院(57% vs 50%,发生率比 1.22, 95% CI 1.12-1.33,p<0.0001)。在基线时未接受有创机械通气的患者中,接受托珠单抗治疗的患者不太可能达到有创机械通气或死亡的综合终点(35% vs 42%,发生率比 0.84, 95% CI 0.77-0.92,p<0.0001)。

综上所述,对于住院治疗的伴有低氧和系统性炎症的新冠肺炎患者,托珠单抗治疗可提高其存活率和其他临床预后,这些治疗益处且不受是否采用呼吸支持和皮质类固醇激素治疗的影响。

Stem cells:低氧预处理+聚集成团可明显提高间充质干细胞移植后的骨骼修复潜能

基于细胞的骨骼肌组织损伤修复方法受细胞存活率差和移植的限制。对间充质干细胞(MSCs)进行短时间的低氧预处理可延长细胞在体内的存活时间,而将MSCs聚集成团可增加体内细胞存活率、营养因子分泌和组织形成。Steve S. Ho等人推测将MSCs聚集成团前予以低氧预处理可增加细胞的存活、增强其促血管生成能力以及促进骨骼修复。研究人员先将人类MSCs置于含氧量为1%的单层培养基中孵育3天(PC3),以环

Aging Clin Exp Res:低氧环境下WBV训练对老年人肌肉质量和功能活动性的影响

衰老伴随着肌肉质量和功能的丧失,这与功能能力的下降有关。由于两种疗法的协同作用,WBV训练与常压低氧暴露相结合可增加有益效果。本研究旨在考察36次WBV训练和常压缺氧暴露联合训练对老年人肌肉质量和功能

Cell Death Dis:低氧通过HIF/HEY1/PINK1通路调节肝癌细胞的线粒体活性

缺氧在癌症中很常见。缺氧,由于缺乏氧气(O2)作为电子受体,导致通过线粒体电子传输链的电子转移效率低下,导致活性氧(ROS)积累,从而可能造成不可逆的细胞损伤。通过可引发各种分子事件的缺氧诱导因子1(HIF-1),细胞能够克服低氧。有关由HIF-1调控的新分子机制的知识对于针对缺氧肿瘤的新治疗干预非常重要。研究人员通过肝细胞癌(HCC)模型,发现HIF-1和Notch信号通路通过交叉作用来控制癌细

Radiology:氧增强MRI肾癌低氧图的价值

本研究旨在验证T1加权氧增强(OE)MRI评价肿瘤低氧耗指标,评价该技术应用于临床的可能性,将结果发表在radiology上。

Brit J Cancer:低氧子宫内膜癌预后不良与血管密度有关

由此可见,在存在高血管密度的情况下,缺氧ECs的不良结局明显可见,这表明血管生成在缺氧EC的转移过程中具有重要作用。这可能需要对这些患者进行有差别的辅助治疗。

Tissue Cell:低氧张力调节小鼠胚胎干细胞的成骨分化

本研究检测了低氧压力对三维培养系统中胚胎干细胞(ESCs)成骨分化的影响。首次证实低氧条件下低氧相关蛋白低氧诱导因子-1α和血管内皮生长因子的表达升高。随后通过测量碱性磷酸酶活性,细胞内钙水平,基质矿化和成骨标志物Runt相关转录因子2和osterix的蛋白质水平来评估低氧ESCs与成骨或无骨生长因子培养基的成骨分化。随后通过测量碱性磷酸酶活性,细胞内钙水平,基质矿化和成骨标志物Runt相关转录因
