Ul cervical screening tool (in spite of 30 inhibition having been reported

Ul cervical screening tool (in spite of 30 inhibition having been reported for such amplification) [37,38]. The frequency of HPV infection detected in the present population agreed with that reported in previous studies carried out on populations having similar characteristics, such as that reported by Ferenczy et al., who described 73.6 crude HPV infection prevalence from cervical samples taken from sexuallyactive HIV-positive women [3]. Nevertheless, HPV infection prevalence in urine in the present study was lower than that in cervical samples; similar data have been reported previously for this type of sample [39]. Such difference in viral detection percentage could have been related to the low number of exfoliated cervical cells present in urine, to the presence of PCR inhibitors in this sample [37] or to methodological issues related with sampling strategies, storage conditions, sample manipulation and DNA extraction method that could affect the HPV-DNA detection [15]; therefore is necessary to continue working on the improvement of protocols for HPV-DNA detection from urine sample. Regarding type-specific distribution, the data obtained from cervical samples agreed with published reports concerning the general Colombian population, HPV-16 being the most prevalent type, followed by HPV-31 [18]. However, urine samples’ typespecific distribution profile revealed some differences compared to that for the cervical samples, HPV-18 being the second most prevalent type, this being similar to worldwide data reported in the pertinent literature [40]. It was also found that HPV-58 and HPV45 were the only two viral types more prevalent in urine samples than in cervical samples, which could have been related to the fact that some viral types may preferentially infect the vagina’s keratinized tissue than the non-keratinized tissue of the Mirin supplier cervix [41]; however, more research needs to be done into HPV infection profiles regarding different areas of the lower genital tract.Table 3.
