Vulvovaginal candidiasis and asymptomatic vaginal colonization in Portugal: Epidemiology, risk factors and antifungal pattern.

Vaginal candidiasis (VVC) is a relevant infection worldwide. In this study, we identified several risk behaviors that may promote VVC and concluded that vaginal microbiologic analyses are urgently required in clinical practice in order to improve the prevention and treatment of this disease.

O16.1 The rapid and near elimination of human papillomavirus (hpv) type 6, 11, 16 and 18 among young high-risk women within three years of the national hpv vaccination programme in australia: findings from a 10-year cross-sectional study

Introduction The national quadrivalent human papillomavirus (HPV) vaccination programme was launched in Australia in April 2007. The aim of this study was to explore the proportion of vaccine targeted HPV genotypes contained in the quadrivalent (4vHPV) and the nine-valent (9vHPV) vaccines detected among young women diagnosed with Chlamydia trachomatis . Methods Women ≤25 years attending Melbourne Sexual Health Centre from 1-July-2004 to 30-June-2014 and diagnosed with chlamydia were included in the analysis. Detection of HPV genotypes was performed on stored cervical or high vaginal samples. The proportions of women who had 4vHPV types (6/11/16/18) and the other five types within the 9vHPV grouping (31/33/45/52/58 alone) excluding 4vHPV types were calculated for each Australian financial year and stratified by age and vaccine eligibility. The proportions of HPV types among unvaccinated women in the post-vaccination period were also calculated to assess herd protection. Results A total of 1,202 women were included in this study. The proportion of samples with 4vHPV types dramatically decreased among Australian-born ≤25 year old females over the 10 year period (6/11 decreased from 16% to 2% [ p trend p trend p = 0 .031), but no decline was seen in the other five types within the 9vHPV grouping (22.5% vs. 25.9%; p = 0 .805). Conclusion Coverage achieved using the 3-dose vaccine was sufficient to largely eradicate 4vHPV types in Australian born women ≤21 years old, within three years of the introduction of the national HPV vaccination program. A strong herd protection was observed among women, with a significant decline in the proportion of 4vHPV in unvaccinated women.
