Abstract

Cutaneous human papillomavirus (HPV) types 1, 2, 4, 7 and 57 are reportedly found in cutaneous warts. However, there are few reports that have investigated the prevalence of mucosal HPV types in cutaneous warts. The aim of this study is to investigate the prevalence of mucosal HPV types in patients with cutaneous warts and to determine any association between HPV types and patient characteristics. We analyzed 62 wart samples that were taken from patients who were diagnosed with cutaneous warts, and 30 normal skin samples were used as negative control. We recorded the following characteristics: sex, age, type of warts, duration of warts, number of warts and patient's immune status. A matrix-assisted laser desorption ionization time-of-flight (MALDI-TOF) mass spectrometry (MS)-based restriction fragment mass polymorphism (RFMP) assay was used for HPV genotyping. Of the total 62 wart samples, 50 samples (81.6%) were positive for HPV genotypes. All of the negative controls (30 samples) using normal skin showed negative reaction. Mucosal HPV types (49 samples, 84.4%) were highly detected, and high- or probable high-risk HPV types (39 samples, 67.2%) were more common than lower risk HPV types (10 samples, 17.2%). A statistically significant association was observed between sex, age, duration of warts and the risk of HPV types. To the best of our knowledge, this is the first study to use the RFMP assay to analyze cutaneous wart-associated mucosal HPV types. The high prevalence of high-risk and probable high-risk HPV in this study is of great significance.
