Слайд 23UAE study Age distribution n = 314


Слайд 24HPV Genotypes in UAE n = 126
8 LR genotypes
14 HR genotypes


Слайд 25Genotype distribution in different age groups (n = 126)


Слайд 26HPV genotypes in UAE
14 HR genotypes : 80
8 LR

: 46

Слайд 27HPV Genome
E1-E7 = “Early” genes (nonstructural)
L1, L2 = Capsid genes
URR =

upstream regulatory region

E6 & E7 proteins play major role in immortality & malignant transformation of infected cells
E5 has role, but not required to maintain cancer phenotype

Munoz et al. 2006.


Слайд 28 Why Cervical Cancer is preventable ?
Natural History of HPV infection


Слайд 30HPV-containing double stranded DNA
‘Empty’ non-infectious virus-like particle (VLP) mimics the virus
Virus-like

particles (VLPs) as HPV vaccine antigens mimic the virus structure

Stanley M, et al. Vaccine 2006; 24(suppl 3):S3/106–113.


Слайд 31Vaccines
Gardasil (2006) :
Contains HPV 16, 18, 6, 11
Cerverix (2009): Contains

HPV 16, 18
Females 10 through 25
For:
Ca Cx
CIN
Adenocarcinoma in situ

Gardasil for males too and for Ca Anus, warts etc

Слайд 50Cervical Cancer is entirely preventable

Vaccination before exposure
Screening after 30 yrs (every

5 yrs)


Though STI,
it does not imply un-faithfullness



Cancer free RAK / UAE by 2020
Become a national achievable goal

Insurance be instructed to approve
Vaccination & Co-testing
