Human Papillomavirus DNA in women having low-grade squamous intraepithelial lesion
Objective: to determine the prevalence and types of HPV in women with low-grade squamous intraepithelial lesions (LSIL). Methods: ninety-six women were sequentially enrolled from the colposcopy clinic. The presence of HPV DNA in the biopsies was determined by L1 consensus primer polymerase chain reaction assay. The samples were co-amplified with biotinylated MY09/MY11/HMB01 and GH20/PC04 beta-globin primers. Reverse line blot hybridization was used for typing the samples. Results: HPV DNA was detected in 28/96 (29.1%) patients. From these, 21/28 (75%) had a single HPV infection and 7/28 (25%) had multiple infection; 29/39 (74.3 %) had high-risk subtypes and 10/39 (25.7%) had low-risk. Thirteen different types were found; most of them were high-risk HPV subtypes (9/13, 69.2%). HPV 58 was the most frequently found subtype. Conclusions: the HPV prevalence in women with LSIL was lower than expected; these results suggest a misclassification in the diagnosis.
