RESUMO
Objective:The study was undertaken to determine the prevalence of different high risk HPV [HR-HPV] genotypes amongst women residing in Kuwait with epithelial abnormalities in cervical smears and to detect any difference in the distribution of these genotypes between Kuwaiti and Non-Kuwaiti women or between the cytological diagnosis groups
Materials and methods:Thinprep specimens from women with epithelial abnormalities on cervical smears were subjected to Aptima HR-HPV assay and those found to be HR-HPV positive were genotyped using the Aptima HPV genotyping assay into three groups [i] HPV 16, [ii] HPV 18/45 and [iii] others
Results: HR-HPV was found in 229 [30.57%] of the 749 cases with epithelial abnormalities. Of the 116 cases subjected to further genotyping, the non-16, 18, 45 genotype accounted for the most prevalent group accounting for 62.93% of the cases, followed by HR-HPV 16 [31.04%] cases and HPV 18/45 [6.03%] of cases. There was no significant difference between Kuwaiti and non-Kuwaiti women nor was any difference noted between the various cytological diagnosis group
Conclusion:Most HR-HPV infections amongst women residing in Kuwait with epithelial abnormalities are due to HPV types other than the 16, 18 and 45. As HPVs 16 and 18 are considered to be the most prevalent HR-HPV genotypes worldwide, causing invasive cancer, the findings of this study is significant from an epidemiological standpoint. It should also be taken into account before undertaking any HPV vaccination program since the available HPV vaccines protect against HR-HPVs 16 and 18 only
