human papillomavirus hpv
Human Papillomavirus (HPV)
  • What is HPV?
    • Viral infection spread through skin to skin sexual contact
    • Group of over 100 different viruses
    • Can cause genital warts
    • At least 30 known strains to cause various types of cancer most commonly cervical, penile and anal cancer

prevalence of hpv
Prevalence of HPV
  • The Center for Disease and Control (CDC) reports that approximately 50% of all sexually active people will get a strain of HPV.
  • 6.2 million people in the United States each year contract a strain of HPV.
  • Men and women in their late teens and early 20s are the typical victims

Center for Disease and Control (CDC)

how to acquire hpv
How to Acquire HPV?
  • Types of Transmission
    • Cutaneous (Skin to Skin)
      • Oral sex
    • Genital
      • Sexual intercourse
    • Perinatal
      • Between mother and child
      • Extremely rare
      • “a pregnant woman can pass HPV to her baby during vaginal delivery and that baby who is exposed to HPV very rarely develops warts in the throat or voice box.” –CDC

hpv induced diseases
HPV Induced Diseases
  • Genital Warts
    • 8.2 million Americans acquire a new genital HPV infection each year
    • Caused by virus strains #6 and #11
    • Symptoms for both female and male include:
      • Soft, moist, pink or flesh-colored swellings in the genital area
      • Can be flat or raised
      • Single or multiple
      • Small or large
      • Sometimes cauliflower shaped
hpv induced diseases continued
HPV Induced Diseases Continued
  • Genital Warts Continued
    • Symptoms continued:
      • Can be painful
      • Can appear any where within the groin region including the thigh and anus
    • Diagnosis is only through visual examination for both male and females
    • Removed by topical or surgical treatments administered by patients or by health care professionals

hpv induced cancers
HPV Induced Cancers
  • Cervical Cancer
    • American Cancer Society predicts 9,700 women will be diagnosed with cervical cancer and 3,700 will die in 2006.
    • HPV infects the women’s cervix and augments the DNA within the cellular structure directly causing abnormal pap smears.

Center for Disease and Control (CDC)

hpv induced cancers continued
HPV Induced Cancers Continued
  • Penile and Anal Cancers
    • 0.2% of cancers of men are cancers of the penis
    • American Cancer Society predicts that 1,910 men will be diagnosed with anal cancer in 2006.

Center of Disease and Control (CDC)

diagnosis of hpv
Diagnosis of HPV
  • Women:
    • HPV is typically diagnosed through pap smears
    • Genital warts is diagnosed through visual examination
    • HPV DNA test allows health care professionals to identify some of the 30 known strains of HPV

Center for Disease and Control (CDC)

diagnosis of hpv10
Diagnosis of HPV
  • Men:
    • Unfortunately, there is no “official” diagnostic tool available to diagnosis HPV.
    • Genital warts, a strain of HPV, are diagnosed through a visual examination.

Center for Disease and Control (CDC)

prevention of hpv
Prevention of HPV
  • Women:
    • Complete regular annual pap smears
    • Avoid risky behaviors
      • Abstinence
      • Condoms
    • Vaccination (Garadsil®)
  • Men:
    • Avoid risky behavior
      • Abstinence
      • Condoms
vaccine garadsil
Vaccine: Garadsil®
  • FDA released in June 2006
  • First vaccination released to help prevent cervical cancer and other reproductive diseases caused by HPV
  • Protects against 4 strains of HPV #6, #11, #16, #18
  • Approved for use in females ages 9-26

Food and Drug Administration (FDA)

garadsil how is it made
Garadsil®: How is it Made?
  • Garadsil® is a recombinant vaccine
    • Genetically engineered through the process and method of manipulating the genetic material of an organism
    • In HPV, each of the 4 virus types are expressed in yeast to create large quantities of the protein which is later purified to make the vaccine
    • The body’s response to the recombinant proteins that then protects against infection by the naturally occurring virus

Food and Drug Administration (FDA)

garadsil
Garadsil®
  • Most effective in girls and women who are have not been sexually active since their chance of exposure to HPV is zero
  • Girls and women who have been exposed to sexual intercourse and are not infected with any the four strains of HPV that Garadsil® protects against, will receive full benefit
  • “currently no test to tell if a girl/woman has had any or all of these four HPV types however very few young women are infected with all four of these HPV types.” –CDC

Food and Drug Administration (FDA)

garadsil15
Garadsil®
  • Garadsil® is not approved for girls under the age of 9 or for women over the age of 26
  • Garadsil® is not approved for men or young boys
  • Researching has been extended to include women over the age of 26, girls under the age of 9 and to include men and young boys into studies involving Garadsil®

Center for Disease and Control (CDC)

garadsil pregnancy
Garadsil®: Pregnancy
  • Pregnant women are discouraged by health care professionals to participate in the promotion of the vaccination
  • “studies suggest that the vaccine has not caused health problems during pregnancy nor has it caused health problems for the infant—but more research is needed. For now, women should complete their pregnancy before getting the vaccine and should complete the pregnancy if she were to find out if she is pregnant after beginning the vaccine series.”

Center for Disease and Control (CDC)

garadsil17
Garadsil®
  • Garadsil® is almost 100% effective in preventing 70% of cervical cancers and 90% of genital warts
  • Immunity of Garadsil® is unknown
  • “studies have followed women for five years and found that women are still protected. More research is being done to find out how long protection will last and if a booster vaccine is needed.” –CDC

Center for disease and Control (CDC)

garadsil cost
Garadsil®: Cost
  • Retail cost about $120 per dose, approximately $360 for the full series
  • Some insurance companies may pay while some may not however the praise Garadsil® is receiving from health care providers, insurance companies may eventually begin to pay

Center for Disease and Control (CDC)

garadsil cost19
Garadsil®: Cost
  • Federal Assistance
    • Vaccines for Children (VFC)
      • Federal health program that will provide the HPV vaccine free of charge to children and teens under the age of 19 who are either underinsured, Medicaid-eligible, American Indian or Alaska native
      • Available at over 45,000 hospitals, private clinics, and public clinics

Center for Disease and Control (CDC)

how garadsil is delivered
How Garadsil® is delivered?
  • Three Injections
  • Given over a 6 month period
    • the first dose is given at the discretion of the patient and health care provider,
    • second dose is followed two months later
    • finally the third and final dose is given is given six months after the first dose.
  • Given typically in the upper arm

Food and Drug Administration (FDA)

what to know before receiving garadsil
What to know before receiving Garadsil®
  • Vaccine series does not protect against all types of HPV or other types of STDS nor will it work for a treatment of HPV
  • Vaccine is not a replacement for annual pap smears
  • Talk to your health care provider thoroughly about all options prior to receiving the vaccination

Center for Disease and Control (CDC)

garadsil prescreening
Garadsil® Prescreening
  • Fortunately, there are no prescreening requirements for women and young girls
  • If girls or women would like to know if they have HPV, a pap test is available however it will not determine any specific strain if she posses any

Center for Disease and Control (CDC)

garadsil and men
Garadsil® and Men
  • Not approved for use in men and young boys
  • Approval has been granted by the FDA to extend research to include boys and men in their continued studies
  • Will reduce number of cancers and outbreak of genital warts
  • Upon approval of use, would benefit females indirectly as well as homosexual relationships

Food and Drug Administration (FDA)

federal laws and vaccinations

  • Effectiveness over long period of time
  • Long term effects
    • health
sexuality among youth
Sexuality among Youth
  • “Government surveys have found that approximately 7% of children have had sexual intercourse before age 13; while about a quarter have done so by age 15. Millions of teens and young adults are contracting sexually transmitted diseases—HPV the most common.”-- (Martha Irvine from Hartford Courant Associated Press).
conclusions
Conclusions
  • Garadsil® holds great promises for women and young girls
  • Unfortunately it is not approved for boys and men and older women, however with time it very well could be
  • Genetic engineering has made it possible for millions of women by giving them the option of receiving Garadsil®
  • Through these advances, technology only holds greater promises for the rest of the population and for future generations
