JCC: IBD男性患者的精子完整性不受硫嘌呤治疗的影响

2019-01-05 MedSci MedSci原创

目前有研究怀疑硫嘌呤药物会破坏男子精子DNA的完整性,浓度和运动性。本项研究通过一系列精液分析研究了硫嘌呤对患有炎性肠病[IBD]的男性精液质量的影响。

背景和目标
目前有研究怀疑硫嘌呤药物会破坏男子精子DNA的完整性,浓度和运动性。本项研究通过一系列精液分析研究了硫嘌呤对患有炎性肠病[IBD]的男性精液质量的影响。

方法
研究人员收集了来自40名患有IBD的男性精液,并前瞻性收集来自40名健康志愿者的样本进行比较。通过精子染色质结构测定[SCSA]和Comet分析评估精子DNA片段。同时参考世界卫生组织[WHO]参数评估了精液量和精子浓度,运动性和形态。另外,研究人员测量了精子细胞DNA中硫鸟嘌呤核苷酸[TGN]的掺入情况。

结果
当进行SCSA评估时,AZA / 6-MP和健康志愿者的IBD患者的精子DNA断裂水平没有差异[ p = 0.23]。AZA / 6-MP的IBD患者的总精子和进行性精子活力显着低于健康志愿者[48.5%对64.5%,p = 0.0003; 27.4%对43.3%,p = 0.0004; ],浓度,体积或形态没有差异。在10对配对样品中观察到相同的趋势。在精子DNA中未检测到TGN掺入,但在精浆中检测到6-MP并且与血液水平相关[r = 0.79,p = 0.02]。

结论
硫嘌呤不会增加精子DNA片段化,但可能会削弱这个IBD队列中的精子活力。本项研究结果支持现有的流行病学数据,即硫嘌呤治疗在孕前是安全的,不应该被放弃。

IBD: 6-硫鸟嘌呤核苷酸水平与克罗恩病患者的粘膜愈合有关

据报道,6-硫鸟嘌呤核苷酸(6-TGN)的水平与接受硫嘌呤维持治疗的克罗恩病(CD)患者的临床缓解有关。6-TGN水平是否与粘膜愈合(MH)相关,很少被研究。因此本项研究的目的是评估CD患者的6-TGN水平与MH之间的相关性。
