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

2017-08-08 AlexYang MedSci原创

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

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,并且是双边的、全身性的和高频率的。频率最高的单倍群为H,且具有组V和K的轻微的超表达,以及组J和T的低频率。另外,研究人员并没有发现单倍群类型与听力损失的关系,然而,年龄被阐释为一个重要的决定因子。

最后,研究人员指出,顺铂引起的耳毒性表现为双边的、全身性的和突出高频率的听力损失。尽管研究人员没有发现单倍群与耳毒性的强相关性,他们的结果阐释了大于60岁老龄风险组的存在,即不考虑先前存在的听力损失,他们对顺铂诱导的听力损失比年轻人更加敏感。
