Genotyping of High-risk Human Papilloma virus (HPV) among Iraqi women in Baghdad by Multiplex PCR

Abstract

Human papilloma virus (HPV) infection is a causative factor for cervical cancer. Early detection of high risk HPV types might help to identify women at high risk of cervical cancer. The aim of the present study was to determine the occurrence ofhigh risk HPV infection in population of Iraqi women in Baghdad by using Multiplex PCR determine the percentage and genotyping of Human Papilloma Virus and to put the best prevention and control program in Iraqi women. Study started at January 2009 to March 2010, cervical samples were collected from 856 women aged 16–70. HPV DNA amplification was performed using HPV High Risk Typing PCR Kit test for qualitative detection and genotyping of HPV types 16, 18, 31, 33, 35, 39, 45, 52, 56, 58, 59, 66 in the cervical swabs. HPV was detected in 106 ( 12,38% ) of the study population, with a range of 16-70 years age groups. Results showed that the overall HPV prevalence twelve genotypes were identified, including HPV-33 (18.60%), HPV-35 (18.60%), HPV-56 (18.60%) ,HPV-39(10.85%), HPV-52 (10.08%), HPV-18 (7.75%), HPV-16 (4.65%), HPV-59 (4.65%), HPV-58(2.32%), HPV-31 (1.55%), HPV-45(1.55% ) and HPV-66( 0.77%). Of 856, 218 women was also tested by pap smear , with normal cytology was 198 ( 90.83%), 24(12.12%) of them were HPV positive, those with abnormal cytology was 20 (9.17 %), 5( 25%)of them was HPV positive. In this study unlike other epidemiological studies, HPV33,35,56 was the most frequent type (55.8%) in Baghdad, followed by HPV39, HPV52, HPV18, HPV16.
