Distribution of HPV infective genotypes in condyloma acuminatum tissues of cervix / 临床与实验病理学杂志

ABSTRACT

Purpose To compare the distribution of 23 kinds of human papillomavirus ( HPV) genotypes in tissues of condyloma acu-minata ( CA) of cervix in 120 women and its clinical significance. Methods Polymerase chain reaction ( PCR) and gene-chips tech-nology were utilized for the detection of 23 kinds of HPV genotypes in tissue specimens from 120 cases of CA in cervix and related ma-terials of all subjects were conducted and analyzed. Results There were 115 positive cases in 120 women with CA in cervix and the rate of total HPV infection was 95. 83% (115/120). The rate of single type was 70. 83% (85/120) and multiple types was 25. 00%(30/120). The predominant type of single infection was HPV11 and the infective rate was 45. 00% (54/120), followed by HPV6 (22. 50%, 27/120). Otherwise, the predominant type of multiple infections was HPV6+11 with the infective rate of 20. 00% (6/30), and HPV11+16 infection accounted for 10. 00% (3/30). Conclusions HPV11, 6, 6+11 and 11+16 are the main genotypes in the pathogenesis of CA in cervix in 120 women. PCR and gene-chip technology can detect single and multiple HPV genotyping in tis-sues of CA in cervix with high sensitivity and specificity. Detection of HPV genotypes could be used to understand the prevalence situa-tion of HPV infection in tissues of CA and tumors of cervix and further to provide references for the research and development of HPV vaccine in women.
