Eur Heart J:HIV感染与胸腹主动脉瘤相关

2021-07-08 MedSci原创 MedSci原创

与未感染的对照者相比,PLWH患主动脉瘤的几率高出四倍,并且HIV状态与主动脉瘤独立相关。在PLWH中,年龄、肥胖和合并乙型肝炎感染与较高的主动脉瘤发生几率相关。

HIV感染者(PLWH)中主动脉瘤的患病率尚未明确。

近日,血管领域权威杂志Eur Heart J上发表了一篇研究文章,研究人员旨在明确HIV状态是否与主动脉瘤独立相关。此外,研究人员旨在确定与PLWH主动脉瘤相关的危险因素。


研究人员从哥本哈根HIV感染合并症研究中招募了年龄40岁以上的PLWH患者(n=594),并与来自哥本哈根一般人群研究的未感染对照者(n=1188)进行年龄和性别匹配。研究人员使用对比增强计算机断层扫描评估了主动脉尺寸。根据欧洲心脏病学会指南定义了主动脉瘤,即主动脉扩张≥50%或肾下主动脉直径≥30mm。

在PLWH和未感染的对照者中,年龄中位数(四分位距)分别为52(47-60)和52(48-61),88%和90%为男性。研究人员在42名(7.1%)PLWH中发现了46处动脉瘤,在29名(2.4%)未感染的对照者中发现了31处动脉瘤(P<0.001)。PLWH的升主动脉瘤和肾下主动脉瘤的患病率明显较高。在调整后的模型中,HIV与主动脉瘤独立相关(调整后的比值比为4.51[95%置信区间为2.56–8.08],P<0.001)。在PLWH中,肥胖和乙型肝炎合并感染与主动脉瘤相关。
 
由此可见,与未感染的对照者相比,PLWH患主动脉瘤的几率高出四倍,并且HIV状态与主动脉瘤独立相关。在PLWH中,年龄、肥胖和合并乙型肝炎感染与较高的主动脉瘤发生几率相关。
