Human papillomavirus antibody responses among patients with incident cervical carcinoma.

The human papillomavirus (HPV) is recognized as a major cause of cervical cancer precursor lesions. HPV serology is a key method in the continuing elucidation of the importance of HPV exposure for cancer development and in predicting HPV-associated diseases. To extend previous HPV serological studies on cervical cancer, serum samples from a consecutive series of 216 women with incident untreated cervical carcinoma and 243 age- and sex-matched healthy blood donors were evaluated for the presence of antibodies against HPV capsids, a marker of past or present HPV exposure, as well as against several cervical cancer-associated defined HPV epitopes. Among the capsid antibody responses, HPV type 16 seropositivity had the strongest association with cervical cancer (OR 2.7, 95% CI 1.8-4.2), but HPV 18 and HPV 33 seropositivities were also significantly associated with cervical cancer (OR 1.6, 95% CI 1.1-2.5; and OR 1.5, 95% CI 1.0-2.2, respectively). The antibody responses against the defined HPV epitopes were confirmed to be associated with cervical cancer, at ORs ranging from 1.4 to 2.0. In conclusion, the study confirms that antibodies against defined HPV epitopes are associated with cervical cancer and provides evidence that seropositivities for HPV types 16, 18, and 33 are associated with cervical cancer risk.

Conization for cervical intraepithelial neoplasia is followed by disappearance of human papillomavirus deoxyribonucleic acid and a decline in serum and cervical mucus antibodies against human papillomavirus antigens.

OBJECTIVE: Our purpose was to investigate whether conization for cervical intraepithelial neoplasia eliminates human papillomavirus deoxyribonucleic acid and effects the levels of serum and cervical mucus antibodies against human papillomavirus antigens. STUDY DESIGN: Analysis of paired cervical brush and serum samples taken from 23 women with cervical intraepithelial neoplasia before and 16 to 27 months after conization was performed for presence of human papillomavirus deoxyribonucleic acid by polymerase chain reaction and for human papillomavirus antibodies by enzyme-linked immunosorbent assay. RESULTS: Four women had recurrent cervical intraepithelial neoplasia, whereas 19 women were disease free. Eighteen of 23 women were positive for human papillomavirus deoxyribonucleic acid before treatment. At follow-up only the 4 women with recurrent cervical intraepithelial neoplasia were positive. Serum immunoglobulin G levels and A levels and immunoglobulin A levels in cervical mucus against most of the tested human papillomavirus antigens had declined at follow-up. CONCLUSIONS: Human papillomavirus deoxyribonucleic acid was regularly eliminated and human papillomavirus antibody levels, especially local immunoglobulin A, declined after efficient treatment, suggesting that conization may be effective for treating the underlying human papillomavirus infection.

Cervical mucus antibodies against human papillomavirus type 16, 18, and 33 capsids in relation to presence of viral DNA.

To investigate whether cervical mucus antibodies against human papillomavirus (HPV) capsids are associated with the detection of HPV DNA or HPV-related cytological diagnoses, 611 samples of cervical secretions from 359 women referred to a colposcopy clinic were tested by an enzyme-linked immunosorbent assay for the presence of immunoglobulin A (IgA) antibodies against HPV capsids of HPV type 16, 18, or 33 and for the presence of cervical HPV DNA by PCR. Among subjects with at least one cervical sample positive for HPV type 16 (HPV-16) DNA, 28.1% also had at least one HPV-16 IgA-positive cervical sample (odds ratio [OR] = 2.9; P = 0.0003). IgA to HPV-18 was also more common among HPV-18 DNA-positive subjects (OR = 3.1; P = 0.0325) and IgA to HPV-33 was more common among HPV-33 DNA-positive subjects (OR = 4.2; P = 0.0023). Cervical IgA antibodies to HPV-16 were also more common among patients with cervical intraepithelial neoplasia, particularly among patients with cervical intraepithelial neoplasia grade I (P < 0.0005). The data indicate that an HPV type-restricted IgA antibody response against HPV capsids is detectable in cervical mucus and is associated with a concomitant cervical HPV infection.
