Popis: | BackgroundWe studied the association between human papillomavirus (HPV) viral load (VL) and HPV concordance.MethodsThe HITCH cohort study included young, heterosexual, recently formed, sexually active couples. Questionnaires and genital samples were collected at 0 and 4 months. Samples were tested for HPV DNA by polymerase chain reaction (PCR; Linear Array). VLs of HPV6/11/16/18/31/42/51 were quantified using type-specific real-time PCR. Correlations between VL and type-specific HPV prevalence and incidence were evaluated using multilevel, mixed-effects linear/logistic regression models.Results We included 492 couples. VLs were higher in penile than vaginal samples. VL at subsequent visits correlated significantly within men (r, 0.373), within women (r, 0.193), and within couples (r range: 0.303–0.328). Men with high VL had more type-specific persistent HPV infections (odds ratio [OR], 4.6 [95% confidence interval {CI}, 2.0–10.5]). High VL in men was associated with prevalent (OR, 5.3 [95% CI, 2.5–11.2]) and incident (OR, 6.7 [95% CI, 1.5–30.7]) type-specific HPV infections in their partner. Women’s VL was associated with type-specific HPV prevalence in their partner at the same (OR, 5.9) and subsequent (OR, 4.7) visit.ConclusionsPersistent HPV infections have limited VL fluctuations. VL between sex partners are correlated and seem predictive of transmission episodes. |
