title: Clinical and epidemiological correlations between the infection with HPV 16 and HPV 18 and female cervical lesions.
abstract: A number of 66 specimens from female cervical lesions were examined for infection with human papillomavirus (HPV) types 6, 11, 16, and 18 by nucleic acid hybridization in dot-blot techniques and 35 sera were tested by the immunodot-blot technique, in order to detect the presence of anti E4 and E7 HPV protein antibodies. The findings were compared with the histologic diagnosis. Fifty-six per cent of specimens contained HPV DNA sequences. In 47% of specimens from cervical carcinoma, HPV 11 was detected in 4 cases, HPV 16 in 21 cases, and HPV 18 in 7 cases. Serum antibodies against HPV 16 E4 and HPV 16 E7 occurred in all the cases of uterine carcinoma, in 4 of 10 cases of CIN I-II, and in 3 of 5 sera obtained from apparently healthy women. The analysis of risk factors disclosed the early onset of sexual activity, a relatively high number of births and abortions before the age of 22 years, the use of oral oestroprogestative contraceptive agents, the presence in anamnesis of genital infections with bacterial flora--Candida albicans, Trichomonas vaginalis, Chlamydia trachomatis, Mycoplasma, etc. Our results showed that HPV typing by nucleic acid hybridization was useful for differentiating low- from high-risk cervical lesions and also tried to elucidate the risk factors associated with HPV infections and progression to malignancy.
