徐州地区2 665例男性患者HPV感染状况和亚型分布特征

Prevalence of HPV infection among 2 665 male patients in Xuzhou area and distribution of subtypes

  • 摘要: 目的 分析徐州地区门诊男性患者人乳头瘤病毒(HPV)感染状况及亚型分布特征。方法 收集2022年5月-2025年4月徐州医科大学附属医院2 665例门诊男性患者脱落细胞或分泌物样本,采用实时荧光聚合酶链式反应(PCR)法进行HPV分型检测,分析感染率和亚型分布特征。结果 2 665例门诊男性患者HPV阳性1 319例,HPV总体感染率为49.49%; 优势亚型前5位依次为:HPV6(14.90%)、HPV11(9.79%)、HPV16(6.75%)、HPV52(6.15%)、HPV58(5.22%)。各年龄组总体感染率、多重感染率、仅低危型感染率、高低危混合型感染率均呈"U"字形分布; ≤19岁组HPV11、HPV6感染率分别为33.33%、20.59%。总体感染率从2022年5月-2023年4月的42.87%升至2024年5月-2025年4月的54.24%; 3个时间周期内,HPV6、HPV11始终为前2位优势型别,HPV52及HPV66等高危型HPV感染率显著上升。尖锐湿疣组总体感染率(66.57%)及HPV6(32.57%)、HPV11(21.05%)感染率均高于其他诊断组。结论 徐州地区门诊男性患者HPV感染率较高且呈上升趋势,青少年及老年男性HPV感染率高,不同诊断组中尖锐湿疣组感染率最高,且以单一低危感染为主,建议结合年龄特征与临床症状制定针对性防控策略以遏制上升趋势。

     

    Abstract: OBJECTIVE To investigate the prevalence of human papillomavirus (HPV) infection among male patients of outpatient department in Xuzhou area and observe the distribution of subtypes. METHODS The exfoliated cells and secretion samples were collected from 2 665 male patients who visited the outpatient department of The Affiliated Hospital of Xuzhou Medical University from May 2022 to Apr. 2025. The HPV subtypes were detected by real-time fluorescent polymerase chain reaction (PCR). The incidence of infections and distribution of subtypes were observed. RESULTS Totally 1 319 of 2 665 male patients of outpatient department were tested positive for HPV, and the overall incidence of HPV infection was 49.49%. The top 5 predominant subtypes were successively as follows: HPV6(14.90%), HPV11(9.79%), HPV16(6.75%), HPV52(6.15%), HPV58(5.22%). The overall incidence of infection, incidence of multiple infections, incidence of low-risk subtypes infection, and incidence of mixed high-risk and low-risk subtypes infections presented a ‘U'-shaped distribution among the age groups. The incidence rates of HPV11 infection and HPV6 infection of the patients with no more than 19 years of age were 33.33% and 20.59%, respectively. The overall incidence of infections increased from 42.87% in May 2022 to Apr. 2023 to 54.24% in May 2024 to Apr. 2025. HPV6 and HPV11 maintained the top 2 predominant subtypes during the three time periods, and the incidence rates of the high-risk subtypes of HPV such as HPV52 and HPV66 exhibited remarkable increase. The overall incidence of infections (66.57%), incidence of HPV6 infection (32.57%) and incidence of HPV11 infection (21.05%) of the condyloma acuminata group were higher than those of other diagnosis groups. CONCLUSIONS The prevalence of HPV infection is high among the male patients of outpatient department in Xuzhou area and shows an upward trend. Notably, the adolescents and elderly males exhibit high incidence of HPV infections, and the condyloma acuminata group exhibits the highest incidence of infections among the diagnosis groups, predominated by single low-risk subtypes of infections. It is recommended to integrate the age with clinical symptoms to formulate targeted prevention and control strategies so as to curb the growing trend.
