- In order to provide a large-scale evaluation of the association with cervical cancer of antibodies against human papillomavirus (HPV) antigens, sera from 233 patients with primary, untreated cervical cancer and from 157 healthy age- and sex-matched blood donors were analyzed for IgG and IgA antibodies against HPV-derived peptide antigens and against bovine papillomavirus. Several serological responses were strongly associated with cervical cancer, notably the IgG response against the HPV 16 epitopes L1:13 (Relative risk [RR]: 5.3), E2:9 (RR: 2.9), and E7:5 (RR: 4.3), and the IgA response against an HPV 18 E2-derived antigen (245:18, RR: 3.1). HPV DNA in corresponding cervical tumors was analyzed by Southern blotting (SB) and polymerase chain reaction (PCR) in 47 patients. Sixty-six percent of the patients carried HPV DNA as determined by SB, 91% of patients analyzed by PCR. Neither the antibody responses, nor the presence of HPV DNA were significantly associated with the biological properties of the tumors.

- Background: Data are lacking regarding which human papillomavirus (HPV) types cause high-grade cervical neoplasia (CIN2+) in people with HIV in Europe. We assessed which HPV types are associated with CIN2+ in women living in Sweden by HIV status. Methods: The Swedish National HIV Registry, the Swedish Population Registry, and the Swedish National Cervical Screening Registry were linked. CIN2+ tissue blocks of 130 women living with HIV (WLWH) and 234 HIV-negative women, matched for country of birth (1:2), were retrieved from bio-banks and HPV genotyped. Adjusted ORs (adjOR), stratified by country of birth, were calculated using conditional logistic regression. Matching was broken for cross-group comparisons. Results: WLWH with CIN2 were less likely to have HPV16 [14% vs. 40%; adjOR 0.1; 95% confidence interval (CI), 0.04-0.56] than HIV-negative women, but among women with CIN3, there was no difference in HPV16 prevalence by HIV status (adjOR 0.9; 95% CI, 0.51-1.70). WLWH were six times more likely to have HPV35 in CIN3 than HIV-negative women (adjOR 6.2; 95% CI, 1.3-30.4). WLWH from sub-Saharan Africa (SSA) had less 9-valent vaccine types, compared with both HIV-negative women born in Sweden (adjOR 0.1; 95% CI, 0.02-0.44) and WLWH born in Sweden (adjOR 0.1; 95% CI, 0.01-0.73), mostly because of decreased HPV16 and increased HPV35. Conclusions: WLWH from SSA were less likely to be covered by the 9-valent vaccine, mostly due to less HPV16 and more HPV35. Impact: This could have implications for HPV vaccines, currently not including HPV35, and for HPV-screening algorithms in women with origin from SSA.
