Scope of Sexually Transmitted
Infections




18.9 million new cases of sexually transmitted
infections occur annually.
 Most STIs remain undiagnosed.
48% of cases occur in people ages 15-24.
By age 24, at least 1 in 3 sexually active people
will have contracted an STI.
Economic costs of STI treatment per year are
estimated to be at least $8.4 billion.

Why Focus On Adolescents?

Younger people are more likely to adopt and
maintain safe sexual behaviors than are older
people with well-established sexual habits,
making youth excellent candidates for
prevention efforts.

Reducing adolescent infections will ultimately
result in fewer infections among all age groups.
PRCH © 2005

Behavioral Risk Factors for STIs
in Adolescents

Age at first sexual intercourse

Sexual activity with a new partner

Multiple sexual partners

Substance use
PRCH © 2005
7
Risk Factors for STIs in
Adolescence

Age at first sexual intercourse

Women with 1st sexual intercourse < age 15 are:



Sexual activity with a new partner


Nearly four times as likely to report a bacterial STI and
More than twice as likely to report PID, as women who first had sex
after age 18.
Several studies have shown that being in a new sex
partnership is a predictor of an STI due to greater uncertainty
about partners’ sexual history and STI status.
Multiple sexual partners


More than one at a time sexual partner increases exposure
and therefore increases risk of STI.
CDC reports that about 16% of 14-19 year olds reported four
PRCH © 2005
or more sexual partners in their lifetime.
8
Cognitive Risk Factors for STIs in
Adolescents

Young adolescents are concrete thinkers:

Often unable to plan ahead for condoms

Serial monogamy in relationships

Personal fable

Unable to judge risk for STIs

“Other people get STIs”

Clinical Cases
PRCH © 2005
13
Case 1

An 18 year old comes into clinic to “get checked
out” for STDs. She has been sexually active with
her boyfriend for 6 months, reports using
condoms “all the time”, and does not think that
her boyfriend is cheating on her, but “you never
know”………..She has no symptoms.
She wants to be checked for GC, CT, HIV and
syphilis.
 What do you send? What is the most likely organism
you will recover?

PRCH © 2005
14
Choice of Screening Labs

Routine screening of all sexually active teens asymptomatic

Gonorrhea – Nucleic acid tests


Chlamydia – Nucleic acid tests


Males – urine; females – cervical >vaginal swab >urine
Universal screening for HIV


Males – urine; females – cervical >vaginal swab>urine
Blood vs. rapid tests
Syphilis

Recommended in high rate areas – VDRL, RPR
PRCH © 2005
15
Chlamydia Screening
All sexually active adolescent females and males
should be screened for Chlamydia at least
annually.
Urine specimen for males; cervical specimen
preferred for females unless pelvic exam not feasible
Provider should counsel that partner must be
informed/treated to prevent reinfection.
Repeat testing in adolescents 3-4 months after
treatment for Chlamydia due to high rate of
reinfection.
PRCH © 2005
16
Gonorrhea Screening


Routine screening for gonorrhea is recommended for
asymptomatic women at high risk of infection, including
young women (under age 25) with two or more sex
partners in the last year.
Vaginal culture remains an accurate screening test when
transport conditions are suitable.



Newer screening tests, including nucleic acid amplification tests
and nucleic acid hybridization tests, have demonstrated
improved sensitivity and comparable specificity when
compared with cervical culture.
Some newer tests can be used with urine and vaginal swabs,
which enables screening when a pelvic examination is not
performed.
Routine screening of sexually active males recommended
PRCH © 2005
17
Guidelines Changes Based On
New Technology

Nucleic Acid Amplification Tests
 More sensitive C. trachomatis (CT) test
 Non-invasive specimens (urine)
 Can detect CT and N. gonorrhoeae (GC) in same
specimen
 Usually more expensive

New data on females – vaginal swab more
sensitive that urine
PRCH © 2005
18
Case 1 continued



48 hours after you have sent her urine screening
labs, a positive probe for Chlamydia is reported
to your office………….
You see her back to discuss the results and she
is still asymptomatic.
How do you treat her? Her partner(s)?
PRCH © 2005
19
Treatment of Asymptomatic
Infections

Single dose treatment appropriate for GC and
CT
Azithromycin 1 gram po
 Ceftriaxone 125 mg IM or Cefixime 400 mg


CDC STI Treatment Guidelines:
Key Counseling Tips


Discussions should be appropriate for the patient's developmental
level and should identify risky behaviors (e.g., sex and drug-use
behaviors).
Providers should:
 Inquire about sexual behavior
 Ask for specifics and avoid heterosexist language
 Do not limit their patient interview to questions about
heterosexual vaginal-penile intercourse
 Assess risk for STIs.
 Counsel about risk reduction, and
 Screen for asymptomatic infection during clinical encounters.
PRCH © 2005
21
CDC STI Treatment Guidelines:
Key Counseling Tips (Cont.)



The style and content of counseling and health
education should be adapted for adolescents.
Careful counseling and thorough discussions are
particularly important for adolescents who may
not acknowledge that they engage in high-risk
behaviors.
Counseling should be direct and nonjudgmental.
PRCH © 2005
22
Case 2






A 16 year old female comes into the clinic with a
complaint of vaginal discharge for one week.
She is sexually active with two partners, using condoms
“most of the time…”
The discharge is described as thick, whitish, with a “bad
smell”.
On exam, you find a homogeneous discharge, cream
color, non-specific odor
On wet prep you see WBCs, normal epithelial cells and
no hyphae.
She has only mild dysuria, no abdominal pain
PRCH © 2005
23
Vaginitis


What organisms/etiologies do you need to
consider?
How does the wet prep help you?
WBCs
 Organisms
 Hyphae
 Trichomonads


What other clinical findings on pelvic exam can
help you?
PRCH © 2005
24
Vaginitis – Clinical Pearls

WBCs present – think inflammation
Yeast – thick, white, adherent discharge
 Trichomonas – thin, greenish, frothy
 Upper infection present – WBCs, neither hyphae or
trichomonads seen, mucopurulent cervical discharge


No WBCs seen
Physiologic leukorrhea
 Bacterial vaginosis – clue cells

Trichomonas Infection


What is it: A microscopic parasite. One of the most
common STIs mainly affecting women
Symptoms:
 Women
 About
50% of women are asymptomatic carriers
 Symptoms include: foul smelling or green discharge
from the vagina, vaginal itching or redness, painful
intercourse, abdominal discomfort, the urge to
urinate and dysuria.

Men
Most men do not have symptoms
 When present, include discharge from the urethra, urge
to urinate, and burning sensation while urinating.

Trichomonas: Treatment



Recommended regimen:
 Metronidazole 2 gm PO x 1
 Tinidazole 2gm PO x 1
Alternative treatment
 Metronidazole 500 mg PO BID x 7 days
Treatment failure
 Retreat with Metronidazole 500 mg PO BID x 7
days
 If repeat failure, treat w/ Tinidazole or
Metronidazole 2gm PO QD x 3–5 d

33
Case 2 continued…..

Additional elements of pelvic exam
Off-white discharge coming from cervical os, similar
to discharge seen in vaginal vault
 No CMT, no uterine or adnexal tenderness, no
abdominal tenderness
 Wet prep significant only for WBCs


Does this change your diagnosis? How do you
diagnose and treat?
PRCH © 2005
34
Mucopurulent Cervicitis

Limited to endocervix
Not involving upper GU structures
 Important distinction for treatment

Can utilize single dose treatment if no upper GU tract symptoms
 Treat for both CT and GC if treating empirically, given
high co-infection rates




Azithromycin 1 gram po
Ceftriaxone 125 mg IM versus Cefixime 400 mg po X 1

Chlamydia
 What is it: STI caused by the bacterium, Chlamydia
trachomatis
 Prevalence: Most commonly reported disease in
the U.S.
 74% of infections occur in persons aged 15-24
 Symptoms:
 Most people with Chlamydia have few or no symptoms
of infection
 May cause an abnormal genital discharge, dysuria, or
increased urinary frequency
 In women, vaginal spotting, dysmenorrhea, dyspaerunia
PRCH © 2005
38
Chlamydia: Diagnosis

Nucleic Acid Amplification Tests (PCR, SDA, TMA)

85–95% sensitive, 98–100% specific

Non-invasive urine specimen (first catch) or

Endocervical swab in females (can use self collected vaginal
swab for APTIMA), urethral swab in males

More expensive than other CT tests (as high as $150)
 Nucleic Acid Probe Tests (GenProbe)
 65–75% sensitive, 95–99% specific
 Sample endocervix or urethra
 Cheaper but less sensitive
PRCH © 2005
39
Chlamydia: Treatment
 1 gm of azithromycin PO x 1 or
 100mg doxycycline BID x 7 days
 When available, single-dose treatment preferable
for adolescents
 Other labs: VDRL or RPR, Gonorrhea, consider
HIV and HSV
PRCH © 2005
40
Gonorrhea
 What is it: An STI caused by Neisseria gonorrhoeae, a
bacterium that can grow and multiply easily in the
warm, moist areas of the reproductive tract, including
the cervix, uterus, and fallopian tubes in women, and in
the urethra in women and men. The bacterium can
also grow in the mouth, throat, eyes, and anus.
 Prevalence: Nearly 260,000 new cases in 2000, 60%
of which were among persons ages 15-24.
 Symptoms: Most common symptoms are vaginal or
penile discharge, or dysuria. Women may have vaginal
bleeding or dysmenorrhea
PRCH © 2005
41
Gonorrhea: Diagnosis



Typical gram- Negative intracellular diplococci smear of
urethral exudate (men) or endocervical material (women)
Recovery of bacteria w/ typical colonial morphology,
positive oxidase reaction, and typical Gram-negative
morphology, grown on selective culture medium
Detection of N. gonorrhoeae by a non-culture lab test:
 Antigen detection test
 Direct specimen nucleic acid probe test
 Nucleic acid amplification test

42
Gonorrhea: Treatment for
Uncomplicated Infections of Cervix,
Urethra, and Rectum
Penicillin historically used but 4 strains of
antibiotic resistance have emerged
 Newer combinations of drugs used:

Ceftriaxone 250 mg IM
 Cefixime/Cefpodoxime
 Avoid fluoroquinolones –resistant


Provide treatment for Chlamydia with
azithromycin or doxycycline unless NAAT
negative

43
Case 3



A young man comes into the clinic complaining
of slight burning on urination for 5 days, and
small ulcer on glans. This started out as a small
vesicle an now is a smaller shallow, slightly
tender ulcer.
He reports being sexually active with a new
partner, who is without symptoms, as far as he
knows……

Genital Herpes

What is it: An STI caused by the herpes simplex viruses type 1
(HSV-1) and type 2 (HSV-2). Most genital herpes is caused by HSV2.

Incidence:



Youth between 15-24 acquire 640,000 new cases each year.
More common in women (approximately one out of four
women) than in men (almost one out of five).
Symptoms: Painful blisters or open sores in the genital area which
may be preceded by a tingling or burning sensation in the legs,
buttocks, or genital region.

Sores usually disappear within 2-3 weeks, but the virus remains in the body
for life and the lesions may recur from time to time.
PRCH © 2005
47
Genital Herpes: Diagnosis
Viral Culture
 Type-specific Serology Testing

 Most
reliable diagnostic test
 Antibodies appear within several days but do
not reach peak until 4–6 weeks
PRCH © 2005

Genital Herpes

Sequelae:
Can cause recurrent painful genital sores - severe in
people with suppressed immune systems
 Frequently causes psychological distress in people
who know they are infected



Chancroid –painful ulcer with inguinal adenopathy that may
be suppurative;



Diagnosed with dark-field microscopy
Primary and secondary treated with 2.4 million units IM Benzathine
penicillin
Diagnosed by culture for H. ducreyi
Treat – Azithromycin 1 gm X 1 dose; Ciprofloxacin 500mg X 1 or
Ceftriaxone 250 mg IM X 1
Distinguish from Lymphogranuloma venereum (LGV)

Painless lesions caused by Chlamydia strains, accompanied by
adenopathy after lesions have healed.

51
Case 4


A 16 year old female comes into urgent clinic at
4:30 complaining of several days of lower
abdominal pain………also with mild dysuria
and some frequency, no significant vaginal
discharge. She is sexually active with occasional
use of condoms.
On exam, she has diffuse lower abdominal pain,
greatest in the midline.

Do you need to do a pelvic exam?
PRCH © 2005
52
Case 4 continued

On pelvic examination:

Off-white discharge in vaginal vault

53
Pelvic Inflammatory Disease

Out-patient Treatment
Ceftriaxone 250 mg IM X 1
 Doxycycline 100 mg BID X 7-10 days
 Add po flagyl as needed for more severe infections


In-patient regimens

Cefoxitin IV and po doxycycline



Add flagyl to regimen if more serious
Clindamycin/gentamicin alternative regimen
Remember: PID is a polymicrobial infection

CT or GC as well as facultative anaerobes
PRCH © 2005
54
PID Clinical Pearls

Single dose therapy is NOT appropriate

You are not treating just CT or GC


Remember: Polymicrobial
Outpatient treatment can be instituted if:
You are fairly sure that there will be compliance
 You can insure follow-up with 48-72 hours
 PO medication will be tolerated
 No pregnancy


If you are not sure, admit.

Minors’ Right to Confidential
Testing and Treatment for
Sexually Transmitted Infections
PRCH © 2005
58
Barriers to Care

Adolescents often delay or forgo preventive health care
due to:
 Concerns
about confidentiality
Stigma
 Insensitive providers
 Lack of insurance and ability to pay
 Lack of transportation

PRCH © 2005
59
Consent to Testing and Treatment

As of July 2005:
 All
50 states and D.C. allow minors to
consent to testing and treatment for STIs
 11 states require that a minor be of a certain
age (generally 12 or 14) before being allowed
to consent
 30 states explicitly include HIV testing and
treatment in the package of STI services to
which minors may consent
1
state requires parental notification in the case of
a positive HIV test

Human Papillomavirus (HPV)
 What is it: HPV includes more than 100 different
strains. More than 30 of these are sexually transmitted,
and they can infect the genital area of men and women
 Incidence: In 2000, 4.6 million HPV infections
occurred among 15-24 year olds.
 Symptoms: Most have no symptoms. Some get visible
genital warts, or have pre-cancerous changes in the
cervix, vulva, anus, or penis.
 Genital warts first appear as small, firm painless bumps in
the vaginal area, on the penis, or around the anus. If
untreated, they may grow and develop a fleshy, cauliflowerlike appearance.
PRCH © 2005
66
Human Papillomavirus (HPV)

Sequelae:





For 90% of women, cervical HPV infection becomes
undetectable within two years
If not detected and treated, HPV can lead to cervical cancer.
Although only a small proportion of women have persistent
infection, this is the main risk factor for cervical cancer.
Treatment: Warts are treated with a topical drug,
trichloroacetic acid, by freezing, with injections of a
type of interferon.
Prevention:




Pap smear testing to detect abnormal cells
Abstinence
Monogamous relationships
Correct and consistent condom use*
PRCH © 2005
67
HPV: Diagnosis



Subclinical infection of the cervix:
 Diagnosed by Pap screening with detection of
squamous intraepithelial lesions
Hybrid capture testing for HPV useful for triaging
borderline (ASC, ASCUS) pap smears
Screening not recommended for women under 30
 Virus is very common among young, sexually active
persons
 Usually not associated with cervical cancer

What is it:



HAV is found in the stool of persons with hepatitis A.
It is usually spread from person to person by orally ingesting
something that has been contaminated with the stool of a
person with hepatitis A.
Incidence:



Hepatitis A
An average of 271,000 hepatitis A infections occurred
every year between 1980 and 1999, 10.4 times the actual
number reported.
HAV is more common in men who have sex with men
Symptoms:

Hepatitis A

Sequelae:




Treatment:




There is no chronic infection.
Once a person is infected with hepatitis A, there cannot be a
reinfection.
About 15% of people infected with HAV will have prolonged or
relapsing symptoms over a 6-9 month period.
No specific treatment for HAV
Rest is recommended during the acute phase of the disease when the
symptoms are most severe.
People with acute hepatitis should avoid alcohol and any substances
that are toxic to the liver, including acetominophen.
Prevention:


Hepatitis A vaccine
Short-term protection against hepatitis A is available from immune
globulin.

HIV/AIDS

What is it: Caused by the human immunodeficiency
virus (HIV), a virus that destroys the body's immune
system.

Incidence: 20,000 new HIV infections occur each
year among persons age 15-24 in the U.S.

Symptoms: HIV infections in adolescents are not
usually symptomatic or diagnosed until adolescents are
in their 20s or even 30s.
 Some develop flu-like symptoms within a month or
two of exposure to HIV.

HIV/AIDS

Sequelae:


Treatment:


If untreated, HIV infection can lead to full blown Aquired
Immune Deficency Syndrome (AIDS).
Four classes of antiretroviral drugs have been developed to
interfere with the activity of these viral enzymes and reduce
viral multiplication and load: nucleoside and nonnucleoside
reverse transcriptase inhibitors, and protease inhibitors.
Prevention:



Abstinence
Monogamous relationships
Correct and consistent condom use

HIV and Adolescents


In 2003, an estimated 3,807 youth aged 13-24
received a diagnosis of HIV/AIDS, representing
12% of people diagnosed that year.
Among youth age 13 to 19:
66% of HIV infections occurred among nonHispanic, black youth
 24% among non-Hispanic white teens
 8% among Latino teens
 Asian and Native American teens together
accounted for less than .009% of reported cases in
this age group


All pregnant women
All patients who know they have had exposure to an
HIV-infected person
All patients in settings with a >1% HIV seroprevalence
All patients from “populations at increased behavioral
or clinical HIV risk,” such as those in STI clinics, teen
clinics with high rates of STIS, or correctional facilities
Patients with “clinical signs or symptoms suggesting
HIV infection (e.g., fever or illness of unknown origin,
opportunistic infection without known reason for
immune suppression)”
Patients diagnosed with another STI

Principles of Effective HIV Counseling,
Treatment and Referral (CTR)
 Protect confidentiality of clients.
 Obtain informed consent before HIV testing.
 Provide clients the option of anonymous HIV
testing.
 Provide prevention counseling and HIV testing
information to all patients.
 Adhere to local, state, and federal regulations and
policies.

Enzyme Immunoassay (EIA) and Western Blot




Rapid Testing




Very sensitive and specific yet neither is perfect
HIV test reported positive only after at least two EIAs and one Western
blot are all positive
Results available in 1 to 2 weeks
As of 2004, three rapid HIV screening tests are available in the US
All three brands provide a definitive negative result and a preliminary
positive result in a matter of minutes
Definitive positive results require a confirmatory tests
Home Testing


As of 2003, one FDA-approved brand is a available in the US for about
$45 for results in 7 business days and $60 for results in 3 business days
Patients collect their own finger-prick blood sample, mail of sample to a
lab and call for anonymous results and telephone counseling a few days
later.

HIV and Young Men Who Have Sex
with Men

Young men who have sex with men (MSM) are
at high risk for HIV infection.

In the seven cities that participated in CDC’s
Young Men’s Survey during 1994-1998, 14% of
African American MSM and 7% of Hispanic
MSM aged 15-22 were infected with HIV.

Condom Use



Correct and consistent use of latex condoms is the
most effective means of preventing STI infection
among sexually active people who are at risk.
Many adolescents lack the skills, access and selfconfidence to obtain, communicate about, and/or use
condoms consistently and correctly.
 Although 2/3 of adolescents report having used
condoms, only 45% report using condoms
consistently.
Providers should provide patients (both male and
female) with step-by-step instructions for putting on a
condom, using models and pictures to facilitate
PRCH © 2005
comprehension.

Putting on a Condom







Step 1: Check the date to assure that the condom has not expired.
Step 2: Tear along one side of the foil, being sure not to rip the
condom inside and carefully remove the condom
Step 3 Air trapped inside a condom could cause it to break.
Squeeze the closed end of the condom between the forefinger and
thumb and place the condom over the erect penis. Leave about a
half-inch of space at the tip of the condom for semen to collect
Step 4 Put the condom on when the penis is erect, before there is
any contact with the other partner's body. While still squeezing
the closed end, use the other hand to unroll the condom down the
full length of the penis.
Step 5 Soon after ejaculation, withdraw the erect penis while
holding the condom in place. Remove the condom only when the
penis is fully withdrawn. Keep both the penis and condom from
touching with your partner's body.
Step 6 : Wrap the condom in a tissue and place it the garbage.
NEVER USE A CONDOM MORE THAN ONCE.
