It is well-documented that human papillomavirus (HPV) DNA and mRNA, particularly that of HPV-16 and HPV-18, were found in over 80% of cervical carcinoma tissues. There never has been any community study of HPV in Saudi Arabia. This study aimed to describe correlation between HPV positivity and cervical changes in this part of the world. We randomly obtained 519 cervical specimens with consent and demographic data from women attending clinics for routine check-up. The specimens were all subjected to Pap smear examination, HPV-DNA detection by PCR with general primers, and HPV genotype determination by reverse-line hybridization with HPV genotype-specific probes. One hundred and sixty four specimens (31.6%) were HPV-DNA positive by PCR, of these 30 showed cytological changes. Sixty four specimens were positive for cytological changes, of these 30 were also HPV-DNA positive. A strong correlation was found between HPV positivity and Pap smear test positivity [p < 0.001, OR (95% C.I.) 2.833 (1.665-4.820)]. Our findings also indicated that hypertension [p=0.012] was also correlated with HPV infection. No other condition in the demographic data was correlated. There was significant association between each of these factors and HPV positivity. It was also found that the majority of positive HPV-DNA cases were among the women who were 25-44 years of age. These results could contribute to the management of HPV infections in Saudi Arabia and should assist health authorities to make proper decisions regarding bivalent or quadrivalent vaccination of women against HPV to reduce the infection and its associated cervical cancer disease.
