Infection Modes and Subtypes of Human Papilloma Virus in Patients / 中国医学科学院学报

ABSTRACT

Objective To investigate the prevalence of human papilloma virus(HPV)subtypes in patients and to provide an evidence for the prevention and treatment of HPV infection and the development of HPV vaccine. Methods Multiplex PCR was used to detect HPV DNA in 6917 patients in Peking Union Medical College Hospital from January 1,2013 to June 30,2015.Totally 5586 patients entered the final analysis after the repeat samples were deleted.The total positive rate of HPV subtypes(including high-risk subtypes including HPV-16,18,31,33,35,39,45,51,52,56,58,59,and 68 and low-risk subtypes including HPV-6 and 11)and the infection status of different age were analyzed. Results The total positive rate of HPV was 36.29%(2027/5586).The positive rate of high-risk subtype was 24.92%(1392/5586)and low-risk subtype was 1.66%(93/5586).The positive rate of multiple was 9.70%(542/5586)and multiple high-risk subtype was 7.75%(433/5586).The positive rate of high-risk subtype and multiple were 25.52%(1366/5353)and 11.16%(26/233)in female and 9.99%(535/5353)and 3.00%(7/233)in male,there were significantly difference(χ=24.61,χ=12.45,all P<0.001).The positive rate of low-risk subtypes(3.86%,9/233)in males was significantly higher than that in females(1.57%,84/5353)(χ=5.84,P=0.007).The high-risk HPV subtype infection mainly was seen in patients aged 31-50 years and the low-risk HPV subtype infection mainly in patients aged 21-40 years.The age of multiple HPV infections from 31-40 years.The lowest turn negative rates of subtype were HPV52 and HPV58.The top three HPV subtypes with the highest positive rates were HPV52,HPV16,and HPV58.Conclusions The positive rates of HPV type are different between male and female patients.The males are mainly infected with low-risk subtypes,whereas the females with high-risk subtypes and the multiple HPV subtypes.The top three high-risk subtypes are HPV-52,16,and 58.HPV subtypes with the lowest secondary negative rates are HPV-52 and 58.HPV infection is mainly seen in young individuals.
