桂西地区3315例女性宫颈人乳头瘤病毒感染状况调查

目的调查桂西地区女性的人乳头瘤病毒(HPV)的宫颈感染现状及基因型分布特点。方法收集3 315例宫颈脱落细胞标本,采用凯普导流杂交进行HPV基因分型检测,对受检者感染结果进行统计分析。结果 HPV总感染率是21.30%(706/3 315),HPV阳性感染者中,以高危型感染为主,占89.52%(632/706)。HPV感染型别中,以单一型感染为主,占72.66%(513/706),二重感染占22.10%(156/706)。21种HPV亚型均有被检出,HPV高危亚型检出率较高的有HPV52(26.77%)、HPV16(15.30%)、HPV58(15.01%)。HPV低危亚型检出率较高的是HPV CP8304(11.90%)、HPV6(3.68%)。不同年龄段妇女的HPV亚型分布有差异,在≤20、20~30、30~40、40~50、50~60、60~70、70岁7个年龄段中,高危型HPV感染率分别是21.62%(8/37)、19.26%(120/623)、17.66%(220/1246)、14.88%(153/1028)、16.83%(51/303)、15.52%(9/58)、30.00%(6/20),各组间差异无统计学意义(χ~2=10.019,P=0.124)。结论桂西地区女性宫颈HPV感染主要以高危型、单一感染为主,感染率较高的HPV亚型依次是HPV52、16、58及CP8304。

Investigation on cervical HPV infection situation among 3 315 females in western Guangxi area

Objective To investigate the infection status quo and genotype distribution of human papillomavirus(HPV) infection situation among females in west Guangxi area.Methods Cervical exfoliative cells samples from 3 315 women were collected to detect HPV genotyping with Cape flow-through hybridization.Then the results were statistically analyzed.Results The overall HPV infection rate was 21.30%(706/3 315),in the females of HPV positive infection,the high-risk type infection was predominant,accounting for 89.52%(632/706).The HPV infection type was dominated by single type infection,accounting for 72.66% the double infection accounted for 22.10%(156/706). The 21 HPV subtypes were detected.The high-risk HPV subtypes with high detection rate were HPV52(26.77%),HPV16(15.30%) and HPV58(15.01%).The low-risk HPV subtypes with high detection rate were HPV CP8304(11.90%) and HPV6(3.68%).The HPV subtypes were distributed differently at different ages.In 7 age groups of≤20,>20-30,>30-40,>40-50,>50-60,>60-70,>70 years old,the infection rates of high risk HPV were 21.62%(8/37), 19.26%(120/623),17.66%(220/1 246), 14.88%(153/1 028), 16.83%(51/303),15.52%(9/58) and 30.00%(6/20) respectively,showing no statistically significant differences among them(χ2=10.019,P=0.124).Conclusion Cervical HPV infection are mainly high-risk HPV subtypes and single type infection in females of western Guangxi area.The HPV subtypes with high infection rate are 52,16,58 and CP8304.
