The association of Humana papillomavirus with cervical neoplasm in Basrah

الملخص EN

-Cervical cytobrush and Pap smears were collected from 103 women attending the outpatient department at Basrah Maternity and children hospital during the period from October 2009 till the end of January 2010.

DNA was successfully extracted from 91 cytobrush samples, amplified for the detection of human papilloma viruses (HPVs) using GP5+/GP6+ primers, in addition to typing using type-specific primers for HPV-16 and HPV-18 genotypes.

The overall HPV prevalence was 20.8% with the dominance of genotype 16 (36.6%) over the genotype 18 (10.5%) and the presence of non-16, non-18 genotype(s) in 42.1% of all HPV positive cases.

Younger women aged 25 years or less were more infected (26.3%) with the dominance of genotype-16 (21.1%) and among women aged 36-45 years, the non-16/non-18 genotype(s) were the more frequently observed (13.3%).

Infection rates were more frequent among women married above 30 years (33.3%) and those with more than one lifetime husband (28.6%).

Women's husband with polygamy practice significantly covariate with HPV infections (P< 0.05).

Significant association (P<0.001) was obvious between infection with any HPV and abnormal cytology.

The non-16/non-18 genotype(s) were more involved (28%) whereas genotype-16 was detected more frequent (20%) than genotype-18 (4%).

In addition mixed infection of both high risk types (16 and 18) was limited only to women with abnormal Pap smears.

In archival blocks, the presence of HPV- DNA was constant in pre-invasive sequamous cervical lesions as all blocks revealed a positive HPV-16 either alone or in combination with genotype- 18.
