Epidemiology of human papillomavirus in Asia: do HPV-52 and HPV-58 play a special role?

INTRODUCTION: Male genital infection by human papillomavirus is of particular importance since it is often asymptomatic. The patient generally presents no clinical lesion. Therefore, men represent an important reservoir of virus, playing a special role in the transmission and perpetuation of the disease. PATIENTS AND METHODS: In the present prospective clinical trial study, 190 sex partners of women with genital infection by human papillomavirus, associated or not with cervical intraepithelial neoplasia, were investigated. All patients were unaware of or denied the presence of a genital lesion. RESULTS: Cytologic examination revealed koilocytosis in 9 cases (4.7%) in the urethra and in 3 cases (1.6%) in the corona of the glans and the distal prepuce. Peniscopy with the previous use of 5% acetic acid revealed white lesions in 97.9% of the patients. Toluidine blue stained most of the lesions. At least one fragment revealed koilocytosis in the histopathologic study of 97 cases (51.05%). CONCLUSION: The three methods complement one another, allowing a more precise diagnosis of this infection in men.

There are more supports for the view that human papillomavirus (HPV) infection might be an etiological factor in the development of cervical cancer when the association of persistent condylomata is considered. Biopsies from 318 cases with squamous cell carcinoma of uterine cervix, 48 with cervical and vulvar condylomata, 14 with cervical intraepithelial neoplasia (CIN), 34 with chronic cervicitis and 24 normal cervical epithelium were collected from 5 geographic regions of China with different cervical cancer mortalities. All specimens were prepared for Dot blot, Southern blot and in situ DNA-DNA hybridizations by using HPV-11, 16, 18 DNA labelled with 32P and 3H as probes to detect viral homologous sequences in samples. Among them, 32 cases with cervical cancer, 27 with condyloma and 10 normal cervical epitheliums were randomly chosen for comparative EM observation. The results showed that: 1), 192 out of 318 (60.4%) cases of cervical cancer were positive for HPV-16 DNA probe (Table I)
