Frequency of human papilloma virus genotypes among woman with genital lesions, in Sanandaj, Iran

Abstract

Background and Aim: Genital wart is the most common sexually transmitted infection and its role in cervical cancer has been confirmed. The aim of this study was to determine the presence of human papillomavirus (HPV) and the frequency of its genotypes in the patients with genital lesions referring to the clinics in Sanandaj, Iran. Material and Method: This descriptive analytical study included 50 women with genital lesions referring to the clinics in Sanandaj City from February 2016 to February 2017. Biopsy samples were examined for four genotypes (HPV 16, 18 (high risk) and HPV 11, 6 (Low risk)) by PCR. Demographic information and risk factors were recorded in a questionnaire for every patient. Using spss v.20 software, data were analyzed by descriptive statistics. Fischer test was used to investigate the relationship between the risk factors and HPV infection. Results: The results showed that 28 cases (56%) were HPV positive. Among the four genotypes of HPV, HPV 6 was the most frequent (32%), followed by the types of 18 (12%), 16 (6%) and 11 (2%). Co-infection of HPV-16 and 18 were found in 2 cases (7.1%).The mean age of the patients with HPV infection was 34.07 ± 8.7 years and the mean age of the first sexual contact was 21.22 ± 4.8 years. No significant association was found between the risk factors and HPV infection (P> 0.05). Conclusion: Considering the high prevalence of HPV infection and its asymptomatic course in many cases, early detection and treatment of the genital warts, especially HPV16 and 18, can lead to prevention of cervical cancer.
