JCO:流感疫苗在癌症患者中的有效性

2019-08-31 Blanchette 医学论坛网

尽管担心疾病或治疗相关的免疫抑制,但季节性流感疫苗依然被推荐给癌症患者。本研究的目的是评估疫苗对实验室确诊的癌症患者流感的有效性。

尽管担心疾病或治疗相关的免疫抑制,但季节性流感疫苗依然被推荐给癌症患者。本研究的目的是评估疫苗对实验室确诊的癌症患者流感的有效性。

患者和方法

我们对加拿大安大略省2010-2011年至2015-2016年流感季节期间接受流感检测的18岁及以上癌症患者进行了观察性试验阴性设计研究。我们将个人癌症登记、呼吸道病毒检测和卫生行政数据联系起来,以确定研究人群和结果。疫苗接种状况由医生和药剂师开具的账单确定。我们使用多变量逻辑回归来估计VE,并根据年龄、性别、农村地区、收入五分位数、癌症特征、化疗暴露、共患病、以前的医疗保健使用、流感季节和日历时间进行调整。

结果

我们确定了26463名癌症患者接受了流感测试,其中4320例(16%)测试阳性,11,783例(45%)接种了疫苗。平均年龄70岁,52%为男性,平均确诊时间6年,69%为实体瘤或恶性肿瘤,23%接受积极化疗。对实验室确诊流感的VE为21% (95% CI, 15%至26%),对实验室确诊流感住院的VE为20% (95% CI, 13%至26%)。实体瘤或恶性肿瘤患者的VE值为25% (95% CI, 18% - 31%),而血液病恶性肿瘤患者的VE值为8% (95% CI, -5% - 19%) (P = .015)。积极化疗对VE无显着影响,尤其是对实体肿瘤患者。

结论和相关性

我们的结果支持为癌症患者接种流感疫苗的建议。血液病恶性肿瘤患者的VE值明显降低,而实体肿瘤患者接受积极化疗的VE值无明显差异。在癌症患者中优化流感预防策略是必要的。

INTENS CARE MED:流感疫苗可降低老年重症监护患者的早期死亡风险

最近,研究人员检查了流感疫苗接种是否会影响年龄≥65岁的重症监护病房(ICU)幸存者患心肌梗塞,中风,心力衰竭,肺炎和死亡的1年风险。

Intens Care Med:重症幸存者流感疫苗接种与1年心肌梗死、卒中、心衰、肺炎和死亡风险

由此可见,与未接种疫苗的ICU幸存者相比,接种流感疫苗的ICU幸存者1年内卒中风险较低,1年死亡风险较低,而与心肌梗死、心力衰竭或肺炎住院治疗的风险没有显著关联。该研究结果支持年龄≥65岁的人接种流感疫苗。

为什么老年人打流感疫苗,效果可能会差?

先提出一个问题,为什么有些老年人群打了流感疫苗后,效果较差呢? 2月20日,《细胞—宿主与微生物》杂志发表一项新发现:流感疫苗在老年人群中效果可能较差的原因,主要与执行体液免疫的B淋巴细胞(人体的一种免疫细胞)有关,B细胞难以产生可充分适应并对抗新出现的流感病毒株的抗体。

流感疫苗可以降低老年患者的死亡风险

奥胡斯大学和奥胡斯大学医院的一项新研究发现,重症监护病房住院的老年患者接种流感疫苗后血栓、大脑出血和死亡风险降低。

《儿童流感的预防与控制建议(2018-2019年)》解读

WHO 数据显示,全球每年有20%~30% 的儿童罹患季节性流感,其中5~9 岁儿童感染率最高。我国流感中心发布的检测报告显示,我国大多数省份已经进入2018—2019 年冬春季流感的流行季节,且儿童感染情况较严重,而接种流感疫苗是其他方法不可替代的最有效预防流感及其并发症的手段。为此,本期就美国儿科学会(AAP)感染性疾病委员会发布的《儿童流感的预防与控制建议(2018—2019 年)》主要更新
