Human papillomavirus infection and typing situation in cervical disease patients in a hospital / 上海预防医学

ABSTRACT

Objective To investigate HPV infection and its typing situation in cervical disease patients in a hospital by flow fluorescence hybridization for detection of human papillomavirus (HPV). [Methods] From January to December 2013, a total of 4 041 cervical disease patients were as research objects.The cervical exfoliated cell specimens were collected and HPV genotypes were detected by flow fluorescence hybridization , while HPV infection rate , genetic subtypes , infection type and age distribution were analyzed . [ Results ] HPV infection was found in 744 cases ( 18 .41%) , in which 603 cases (14.92%) were single subtype and 141 cases(3.49%) multiple subtypes of infection.All 26 kinds of HPV subtypes available to detection were detected .The common subtypes were HPV-16, 52,58,39,18, 61,59,6 etc., in which HPV-61,6,11 subtypes were with low-risk and HPV-16,52,58 subtypes with high-risk.More common type of infection was high-risk subtype , in which single high-risk subtype infection was 13.07%(528/4 041) and multiple high-risk subtypes infection 2.15%(87/4 041).The highest rate of HPV infection(22.22%) was found in the women 31 to 40 years of age, and the lowest(13.99%) in those above 50 years.In all age groups , the high-risk subtype infection was found with the highest detection rate . [ Conclusion] Patients with cervical disease are found to have higher HPV infection rate with wider distribution genotype .Flow fluorescence hybridization proves a fast and effective method to detect HPV infection, and HPV genotyping has significance for prevention and treatment of cervical disease .
