- The association of HLA class II DQB1 and DRB1 alleles with the development of cervical carcinoma was studied in 150 Swedish patients using PCR-based HPV and HLA typing. The association of cervical carcinoma with alleles encoding the DQ3 antigen, previously found among German and Norwegian patients, was not observed in the Swedish patients. Five DQ-DR haplotypes were indicated to be positively associated with development of cervical carcinoma in the Swedish patients. Two of these HLA associations were specific for HPV 18 infected patients, suggesting that the ability of the oncogenic HPV 18 to cause more rapid-transit tumors than other high risk HPV types may be due to a deficiency in antigen presentation by the HLA molecules encoded by carried on these haplotypes.

- BACKGROUND: Human papillomavirus (HPV) DNA testing may be useful in clarifying equivocal cervical cytologic interpretations. One application might be to standardize the meaning of equivocal interpretations from laboratories in various regions. Because international differences may be particularly marked, international comparisons of emerging data will require clear translations of "equivocal" and similar terms. METHODS: To perform a three-country comparison, the authors selected a morphologically diverse set of 188 conventional Papanicolaou tests initially classified as "squamous atypia" from a study of more than 20,000 women in Portland, Oregon (1989-1990). Previously, five U.S. expert cytopathologists independently interpreted the slides with screening cytotechnologists' marks in place. For this comparison, one British and two Scandinavian reviewers involved in HPV research reviewed the slides after original marks had been removed. The authors compared all eight reviewers' classifications of negative, equivocal, or abnormal in a series of pairwise comparisons using the kappa statistic. They then compared cytologic interpretations with HPV DNA testing. RESULTS: Oncogenic HPV DNA detection was significantly associated with increasingly abnormal interpretations for each reader. The British reader tended to rate tests as more abnormal than the American pathologists did, whereas the Scandinavians tended to rate tests as more normal. Reference to the HPV DNA standard clarified the tendency of readers to render systematically more or less severe interpretations. For example, the Scandinavian cytologists discounted subtle (often HPV-associated) changes in favor of cytologic certainty, making HPV triage of equivocal tests less applicable there. CONCLUSIONS: International research on cytopathology, particularly on the possible uses of HPV DNA testing, will require calibration of local cytologic definitions.

- In a prospective cohort study on the prevalence of HPV in a group of female Swedish students, we obtained repeated cytological specimens during a period of 2 years, for cytological diagnosis and PCR detection of HPV. The group comprised 98 girls, sampled between 15 and 17 years, and 82 of them completed the study. The girls were also followed every sixth month by a structured face-to-face interview regarding sexuality. Only the sexually experienced girls harboured HPVDNA in the cervix with a cumulative prevalence of 37% and HPV16 was the most common type encountered. Almost half of the infected girls were lacking any clinical or subclinical signs of HPV infection. There was a positive correlation between the presence of HPV and the number of coital partners. The time period since coitarche also had importance for the HPV detection rate.
