Otol Neurotol:口服候选临床阶段药物SENS-401可以有效的减少铂引起的听力损失

2017-08-12 AlexYang MedSci原创

SENS-401是一种口服的临床阶段药物,也许在体内模型中可以减少铂化合物引起的听力损失和耳蜗移植损伤。铂化合物与听力损失有关,可以在儿科癌症人群中引起明显的学习和行为障碍,并且目前还没有临床解决方法。之前,有报道表明了在体内试验中,SENS-401可以改善声创伤诱导的听力损失。最近,研究人员利用一系列的铂化合物敏感细胞系(NIH:OVCAR-3、 SK-N-AS、 NCI-H460和FaDu)评

SENS-401是一种口服的临床阶段药物,也许在体内模型中可以减少铂化合物引起的听力损失和耳蜗移植损伤。铂化合物与听力损失有关,可以在儿科癌症人群中引起明显的学习和行为障碍,并且目前还没有临床解决方法。之前,有报道表明了在体内试验中,SENS-401可以改善声创伤诱导的听力损失。

最近,研究人员利用一系列的铂化合物敏感细胞系(NIH:OVCAR-3、 SK-N-AS、 NCI-H460和FaDu)评估了SENS-401对铂化合物IC50值的影响,并在SENS-401药物处理铂化合物诱导的听力损失小鼠模型中的当时(8mg/kg, day 1)和处理14天后(6.6, 13.2, 26.4mg/kg/d),进行了听力脑干响应和畸变产物耳声发射测试。另外,研究人员还对肌球蛋白-VIIa免疫标记后,进行了耳蜗外听毛细胞计数。

研究发现,在评估的所有细胞类型中,SENS-401(最多到10微摩尔)的添加没有影响到铂化合物的毒性。在体内试验宋,SENS-401剂量显著的改善了听力脑干响应阈值变动(最大到30dB),并且畸变产物耳声发射振幅减少(最大到19dB)。身体重量和存活率在接受安慰剂的小鼠和那些接受26.4mg/kgSENS-401小鼠之间没有显著的差异。然而,SENS-401处理后的小鼠中展现出了比对照组显著更多的存活的外周听毛细胞(p<0.001),最多达到了11倍。最后,研究人员指出,体内和体外试验支持了SENS-401的保护潜力和耐受力,并且不影响化学疗法的作用。口服SENS-401是一种治疗铂化合物诱导耳蜗毒性的有希望的候选药物。

Int J Otolaryngol: 线粒体DNA单倍群和顺铂诱导听力损失关系的缺乏

许多应用于癌症化学疗法的药物能够产生活性氧类物质,从而导致各种并发症,包括肾毒性、心脏毒性和耳毒性。最近,有研究人员进行了一个接受化学疗法的癌症病人群体的单倍群分析,并且比较了与听力损失相关的因素。研究中的观察群体研究包括了经历化学治疗病人的纯音听力测定。研究人员对医疗历史、听力损失风险因子的存在、不良习惯和与单倍群的相关性进行了探究。研究发现,40%的病人在接受铂治疗后发展为听力损失,并且是双边

JAMA Otolaryngol Head Neck Surg:9岁到11岁儿童的听力损失的流行度分析

听力损失(HL)是造成残疾的一个主要原因,并且对私人生活和工作带来负面影响。最近,有研究人员进行了旨在描述9到11岁儿童群体的感官听力损失(SNHL)的流行程度,并且调查了所谓的风险因子与SNHL的相关性。该研究在荷兰鹿特丹的一个普通的、非临床的小儿社区进行,时间为2012年到2015年。研究人员利用新一代R研究进行了代表性的评估,即从婴儿时期直到成年的基于群体的纵向群体研究。在新一代R研究中,参
