ABSTRACT
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.
ABSTRACT
Objective To analyze the characteristics of 5 152 cases HPV genotyping in Guangxi province ,which will be benefit for the control of HPV infection and provid experimental evidence for clinical treatment .Methods Statistically analyze the positive detection rate of all the HPV subtypes ,the differences in the positive rate between people of different genders and ages .Results The total positive rate was 37 .46% (1 930/5 152) .The subtypes with the top seven positive rates were HPV16 (5 .90% ) ,HPV52 (5 .36% ) ,HPV58(4 .04% ) ,HPV6(3 .40% ) ,HPV53(2 .66% ) ,HPV11(2 .43% ) ,HPV18(2 .19% ) ,which were mainly high‐risk subtypes .The total positive rate of male patients was 87 .71% ,while female patients was 34 .45% ,the total positive rate of male pa‐tiets was higher than women .For the positive rate of HPV6 ,HPV11 and HPV58 ,male patients were higher than women ,while for HPV52 female patients was higher than men(P<0 .05) .High‐risk HPV6 ,HPV11 ,HPV42 ,HPV43 infection were characterized by the tendency of younger patients ,the differences were statistically significant(P<0 .05) ,the positive infection rate of patients equal or less than 20 years old(75 .51% ) was higher than other age groups .Conclusion HPV infection rates are very high in some re‐gions of Guangxi ,and attention should be paid to male HPV infection .The subtypes with the top seven positive infection rate are mainly high‐risk subtypes .Low‐risk subtypes such as HPV6 ,11 ,42 ,43 are characterized by the tendency of younger patients .The distribution of HPV infection was affected by region ,gender and age .The investigation of HPV subtypes in Guangxi and do HPV screening in different age groups could help the prevention of cervical cancer and understanding HPV infection outcome .
