Methods Forty eight patients with pathologically diagnosed common warts were screened for the presence of HPV with HPV type-specific PCR and direct sequencing analysis. The genomic diversity of HPVs prevalent in Chinese patients was analyzed based on LCR. Results Forty one (85.5%) samples were positive for HPV DNA, 13(31.7%)-HPV-57, 12(29.3%)-HPV-la, 7(17%)-HPV-27 and 5(12.2%)-HPV-2a. Four cases were infected with two different HPV types, two (4.9%) with HPV-la and HPV-27, one (2.4%) with HPV-1 and HPV-57 and one (2.4%) with HPV-27 and HPV-57. In contrast to the prevalence of single strain of novel HPV-57 variant and HPV-1 prototype, two HPV-2 and three HPV-27 novel variants were found to circulate in Beijing. Conclusion HPV-1, -2, -27 and -57 are predominantly prevalent in patients with common warts in Beijing.展开更多

The prevalence of cutaneous warts varied from 2.4%-12.9%, with common warts, planta warts and genital warts being the most common ones. About 67% of patients with warts might resolve spontaneously within 2 years, while in some patients warts persist for years. A cellular immune response is essential for the clearance of HPV. Treatment modalities are usually ablative.展开更多
