Detection of human papillomavirus DNA in cases of sexually transmitted diseases (STD)

: Human papillomavirus (HPV) has been detected on the genitalia without any macroscopic abnormality and the possibility of latent infection of HPV has been suggested. Using Vira Type (Toure Co.), we have detected 7 genotypes of HPV DNA under a high stringent condition on the genitalia of patients with sexually transmitted diseases (STD), who were suspected of having had many sexual partners. In male cases of STDs other than condyloma acuminatum, the HPV-positive rate of the glans and sulcus coronarius was 4.7% (5/106). In healthy men, the HPV-positive rate was 6.1% (2/33), while in chronic prostatitis cases it was 3.4% (7/205) and in benign prostatic hypertrophy cases HPV was not detected. In female cases of STDs other than condyloma acuminatum, the HPV-positive rate of uterine cervix was 5.1% (3/58). In pregnant women, the HPV-positive rate was 4.6% (9/197). With regard to the HPV-positive rate within different age groups of STD and non STD cases, the rate tended to be higher in young people. After several weeks, follow-up studies were conducted on HPV-positive cases. HPV DNA was detected in one case of 10 males STD cases and two of 10 pregnant women, and the HPV DNA was the same type as at the first examination. However, after 3-4 months, all three of these cases had become negative for HPV DNA.
