Human Papillomavirus (HPV) Genotypes in Genital Warts in Colombian Population

Genital WartsHPV Infections

HPV infection has been recognized as the most prevalent sexual transmitted infection worldwide. Burden of many HPV related diseases is well known particularly regarding the different associated cancers (cervical, anal, vaginal, vulvar, oro-pharyngeal) (3) ; however, there is much less available information on the general burden of genital warts, the associated HPV types, the costs of related medical treatments and the knowledge and perceptions towards the disease and its prevention. Objectives: To determine the HPV genotypes distribution in genital warts in the study population. To assess the knowledge about transmission & prevention of HPV infection related diseases To determine the direct medical costs of genital warts attention.

The Psychosocial and Economic Burden of Genital Warts

Female Genital Warts

Considering the importance of HPV(human papilomavirus) and related diseases in Brazil, and the lack of studies about both the economic and the psychosocial burden of these diseases, BEMFAM, a Brazilian non-governmental organization that provides reproductive health services and technical support to local governments proposes a study to measure the psychosocial and economic burden of genital warts.

Topical 5-ALA Photodynamic Therapy for the Treatment of Verruca Vulgaris

Warts

Photodynamic therapy (PDT) has been developed as a promising new cancer treatment modality, which involves the uptakes of a photosensitizer by tumor cells, followed by the activation of photosensitizer with approximate wavelength of light. The mechanisms of the PDT-induced cytotoxic effect relate to singlet oxygen and other reactive oxygen intermediates generated by PDT, which give rise to cellular stress and cause cell death. Previously, using the homemade LED light source, we have shown that ALA-PDT is effective for the treatment of premalignant lesions such as mucosal dysplasia and carcinoma in situ of oral cavity. Due to the advantages of low cost, high reliability, and portability, LED light source provides an alternative approach for the light irradiation of PDT. Verruca vulgaris are benign skin papillomas caused by the human papilloma virus (HPV). They are very common and can affect many different sites including the face, hands, feet and genitalia. Although the present therapeutic approaches are more or less effective in eradicating the lesions, relapses are very common. Furthermore, at times the anatomical location and depth of lesions often make the treatment difficult, time-consuming and painful. Therefore, it is necessary to develop new modalities for wart treatment. The purpose of this clinical trial is to develop topical ALA-PDT as an alternative treatment of wart but without the unwanted side effects of pain and burning. To fulfill this goal, the following works will be performed. First, topical ALA formulation and LED array will be specifically designed and developed for the skin lesions. Second, the efficacy of the ALA formulation designed for wart treatment will be evaluated with in vivo fluorescence imaging system. Third, the therapeutic efficacy of ALA-PDT will be evaluated by using a LED array designed for skin irradiation. Forth, the unwanted side effects of pain and burning will be further compared between red and green LED array.
