Abstract
PDF - Objectives
Prophylactic vaccines against high-risk human papillomaviruses (HR-HPVs) hold promise to prevent the development of higher grade cervical intraepithelial neoplasia (CIN 2+) and cervical cancer (CC) that develop due to HR-HPV genotypes that are included in HPV vaccines, but women will continue to develop CIN 2+ and CC due to HR-HPV genotypes that are not included in the quadrivalent HPV vaccine (qHPV) and 9-valent HPV vaccine (9VHPV). Thus, the current vaccines are likely to decrease but not entirely prevent the development of CIN 2+ or CC. The purpose of the study was to determine the prevalence and determinants of CIN 2+ that develop due to HR-HPVs not included in vaccines.
Methods
Study population consisted of 1476 women tested for 37 HPVs and known to be negative for qHPVs (6/11/16/18, group A, n = 811) or 9VHPVs (6/11/16/18/31/33/45/52/58, group B, n = 331), but positive for other HR-HPVs. Regression models were used to determine the association between plasma concentrations of micronutrients, socio-demographic, lifestyle factors and risk of CIN 2+ due to HR-HPVs that are not included in vaccines.
Results
The prevalence of infections with HPV 31, 33, 35 and 58 that contributed to CIN 2+ differed by race. In group A, African American (AA) women and current smokers were more likely to have CIN 2 (OR = 1.76, P = 0.032 and 1.79, P = 0.016, respectively) while in both groups of A and B, those with higher vitamin B12 were less likely to have similar lesions (OR = 0.62, P = 0.036 and 0.45, P = 0.035, respectively).
Conclusions
We identified vitamin B12 status and smoking as independent modifiable factors and ethnicity as a factor that needs attention to reduce the risk of developing CIN 2+ in the post vaccination era. Continuation of tailored screening programs combined with non-vaccine-based approaches are needed to manage the residual risk of developing HPVrelated CIN 2+ and CC in vaccinated women. -
