ABSTRACT
Objective Large sample data of HPV genotyping on anus and anal canal condyloma acuminata (CA) tissue were rarely reported in China.This study is aimed to investigate the clinical value of the distribution of different kinds of genotype of human papillomavirus within regional (mainly in Jiangsu Province)patients of both male and female with anus and anal canal condyloma acuminata(CA).Methods We collected tissue specimens from 326 male and female patients with anus and anal canal condyloma acuminata(CA) from 4 hospitals in Jiangsu and Anhui provinces from August 1985 to July 2017.HPV DNA was extracted and through the combination of gene chip and polymerase chain reaction technology,23 genotypes of HPV were detected.Results Among 179 male cases,136 were found with HPV.The total HPV detection rate was 75.98％(136/179),and of which,single genotype detection rate was 55.31％ (99/179) while multiple genotypes detection rate was 20.67％ (37/179).Meanwhile,in the 147 female cases,108 cases with HPV represented the total HPV detection rate of 73.47％ (108/147),of which single genotype detection rate was 48.79％ (72/147) and multiple genotypes detection rate was 24.49％ (36/147).342 were detected for all the genotype frequency totally and the low-risk HPV genotype was appered for 267 times while 75 times for high-risk HPV in this term.Among all the genotypes,6,11,16,18 took the top 4 respectively.Conclusion Among the regional (mainly in Jiangsu Province) male and female cases with anus and anal canal (CA),HPV 6,11,16,18 were the most common types.HPV was mostly distributed in the population of male younger than 30 years old.
ABSTRACT
Objective To investigate the prevalence and genotype distribution of human papillomavirus (HPV) in the region of Guangxi.Methods We retrospectively analyzed 15774 individuals from the Outpatient and inpatient Unit as well as Physical Examination Departments of the People's Hospital of Guangxi Zhuang Autonomous Region between May 2010 and March 2017.Exfoliated c ellsor swab specimens were collected,and the genotypes of HPV were determined by Polymerase Chain Reaction (PCR) and reverse blot assay.Results The prevalence of HPV infection was 38.54％ (6080/15774).The infection rate of single genotype and multiple genotypes were 25.60％ (4038/15774) and 12.95％ (2042/15774),respectively.In single infection patterns,the most common genotypes included HPV 6 (10.54％,1663/15774),52 (3.91％,616/ 15774),16 (2.16％,340/15774),11 (2.14％,338/15774),and 58 (2.00％,316/15774).While among the multiple infections patterns,HPV 52+53 (4.26％,87/2042) and 52+58 (3.23％,66/ 2042) were common,and followed by HPV 16+43 (2.40％,49/2042),16+52(2.30％,47/2042),6+42 (2.15％,44/2042) and 6+43 (2.15％,45/2042).HPV 52,16,58,51,53 and 18 were the top six high risk (HR) genotypes of HPV,accounting for 26.77％ (4222/15774,95％ CI =26.08-27.46);while HPV 6,11 and 43 were the leading low-risk (LR) genotypes of HPV,accounting for 27.77％ (4380/15774,95％CI =27.07-28.47).The overall ratio of single infection to multiple infections was 1.98 (4038 vs.2042).Conclusion HPV 6,52,16,11,58,18 were the main HPV infection genotypes,and 52+53 and 52+58 were common infection combinations in Guangxi Zhuang Autonomous region.The HPV multiple infections were increased.Apparently,more HPV low risk genotypes were seen in male patients that should be aware.
