Clin Gastroenterology Hepatology: 克罗恩病患者肛管疾病高发且易患人乳头病毒

2018-11-11 MedSci MedSci原创

肛管癌发病率的增加与肛门人乳头瘤病毒(HPV)的感染有关。本项研究的目的是评估在克罗恩病患者肛管HPV感染的患病率和危险因素。

背景与目的
肛管癌发病率的增加与肛门人乳头瘤病毒(HPV)的感染有关。本项研究的目的是评估在克罗恩病患者肛管HPV感染的患病率和危险因素。

方法
研究人员分析了469名患者(中位年龄54岁,52%女性),并收集了他们的肛门组织样本,其中包括112名接受免疫抑制治疗的患者和101名患有炎症性肠病的患者(70名患有克罗恩病),研究人员使用INNO-LiPA测定检测HPV并进行基因分型。通过单变量和多变量分析评估任何HPV,高风险HPV(HR-HPV)和HPV16感染的风险因素。

结果
研究人员发现HPV16是最普遍的基因型(检出率为7%),其次是HPV51,HPV52和HPV39。HR-HPV在女性样本中的比例(23.1%)明显高于男性(12.8%)(P= .0035);HR-HPV和HPV16在克罗恩病患者中的比例(30.0%)明显高于非克罗恩病患者(18.1%)(P= .005)。在多变量分析中,女性,性传播疾病史,过去一年的性伴侣数,主动吸烟和免疫抑制治疗是肛门HR-HPV感染的独立危险因素。

结论
三分之一在肠科接受结肠镜检查的患者被发现患有肛管HPV感染,克罗恩病患者的比例明显高于非克罗恩病患者。
