Herpes Simplex Virus (HSV)

HSV: Clinical Presentation
Primary Infection
Recurrent Disease





Prodrome phase:
Tingling/itching of skin
Appearance of painful
vesicles in clusters on an
erythematous base
Vesicles ulcerate then
crust over and heal
within 7-14 days
Viral shedding continues
for up to 2-3 weeks


After primary infection,
virus migrates to sacral
ganglion and lies
dormant
Reactivation occurs
due to various triggers
Reoccurrence is usually
milder and shorter in
duration

Clinical presentation
Viral culture

Skin biopsy

HSV: Treatment Considerations
 Antivirals
 Lesions may be bathed in mild soap and water
 Sitz baths may provide some relief
 Sex partners may benefit from evaluation and
counseling
 Transmission is possible when lesions not present
due to viral shedding
9
Syphilis
10
Syphilis: Clinical Presentation
Primary / Infectious / Early Syphilis Stage:
Primary Phase
 Primary chancre
 Begins as papule and erodes into painless ulcer with
a hard edge and clean base
 Usually in the genital area
 Appears 9-90 days after exposure
 Can be solitary or multiple (eg. kissing lesions)
 Heals with scarring in 3-6 weeks and 75% of patients
show no further symptoms

Syphilis: Clinical Presentation (continued)
Primary / Infectious / Early Syphilis Stage:
Secondary Phase
 Occurs 6 weeks – 6 months after chancre
 Lasts several weeks
 Accompanied with fever, malaise, generalized
lymphadenopathy, and patchy alopecia
 Maculo-papular rash usually on palms and soles
 Condyloma lata on perianal or vulval areas
 Possible mild hepatosplenomegaly

Syphilis: Clinical Presentation (continued)
Secondary / Latent Stage:
 Positive serology
 Rapid Plasma Reagin (RPR)
 Venereal Disease Research Lab (VDRL)
 Patients are asymptomatic and not infectious
after first year, but may relapse
 One-third will convert to sero-negative status
 One-third will stay sero-positive but asymptomatic
 One-third will develop tertiary syphilis
16
Syphilis: Clinical Presentation (continued)
Tertiary Stage:
 Cardiovascular: Aortic valve disease, aneurysms
 Neurological: Meningitis, encephalitis, tabes
dorsalis, dementia
 Gumma formation: Deep cutaneous
granulomatous pockets
 Orthopedic: Charcot’s joints, osteomyelitis
 Renal: Membranous Glomerulonephritis
17
Syphilis: Diagnosis
Requires demonstration of:
 Organisms on microscopy using dark field
 Positive serology on blood or cerebrospinal
fluid (CSF)
Non-Specific Treponemal Tests:
1. Venereal Disease Research Laboratory
(VDRL)
2. Rapid Plasma Reagin (RPR)
18
Syphilis: Diagnosis (continued)
 Positive serology on blood or CSF
 Specific Treponemal Test:
1. Fluorescent Treponemal Antibody Absorption
(FTA-ABS)
2. Microhemagglutination-Treponema pallidum (MHA-TP)
 Organism may not be cultured but diagnosis cannot
be determined by clinical findings only
19
Syphilis: Treatment Considerations
 Primary/ secondary/ latent stage: Benzathine
penicillin
 Neurosyphilis: Penicillin G
 Ask about penicillin allergy before treatment
 Jarisch-Herxheimer reaction may occur
20
Chlamydia
21
Chlamydia: Clinical Presentation





Mucopurulent cervicitis/vaginal discharge
Dysuria
Lower abdominal pain
Urethritis, salpingitis, and proctitis
Post coital bleeding – friable cervix
Key Considerations:
 50% of females are asymptomatic
 Sterile pyuria with urinary tract symptoms should
trigger you to think chlamydia

23
Chlamydia: Diagnosis
 Chlamydia culture
 New tests include:
 Direct immunofluorescence assays (DFA)
 Enzyme immunoassay (EIA)
24
Chlamydia: Treatment Considerations
 Antibiotics
 Azithromycin
 Evaluate and treat sexual partners
 Avoid sex for seven days after completion of
treatment
25
Gonorrhea

Gonorrhea: Clinical Presentation
Areas of Infection





Urethra
Endocervix
Upper genital tract
Pharynx
Rectum
Signs and Symptoms
 Frequently asymptomatic





Vaginal discharge
Abnormal uterine bleeding
Dysuria
Mucopurulent cervicitis
Lower abdominal pain
28
Gonorrhea: Diagnosis
 Clinical exam
 Cervical culture
 Polymerase chain reaction (PCR) or ligase
chain reaction (LCR)
 Gram stain–polymorphonucleocytes with
gram negative intracellular diplococci

Gonorrhea: Treatment Considerations
 Intramuscular Ceftriaxone
 For pregnant women only:
 Ceftriaxone single dose but substitute Quinolones
with Erythromycin
 Do not treat with Quinolones or Tetracyclines
 Evaluate and treat all sexual partners
31
Trichomoniasis
32
Trichomoniasis: Clinical Presentation
Signs and symptoms:




Vulvar irritation
Dysuria
Dyspareunia
Pale yellow, malodorous - gray/green frothy
discharge
 Strawberry cervix, inflamed and friable

Trichomoniasis: Diagnosis




Flagellated, motile trichomonads on wet mount
Vaginal pH > 4.5
Diagnosis confirmed by microscopy
Other FDA approved tests:
 OSOM Trichomonas Rapid Test
 Affirm VP III
35
Trichomoniasis: Treatment Considerations
 For HIV-infected women: same treatment as
non-HIV infected women
 Metronidazole or Tinidazole
 Sex partners have to be treated
36
Providing Culturally Competent Care
The following factors can influence a woman’s
understanding of STDs and need for screening:
 Language and literacy level
 Cultural and social background and its impact on her
understanding of health, illness, and the female anatomy
 Comfort with discussing sexual health issues
 Comfort and previous experience with STD screening or
testing
 History of sexual abuse and/or domestic violence may
cause anxiety and exam refusal
37
Pearls of Wisdom
 Get comfortable with obtaining a thorough sexual
history
 Check oral cavity if genital STD suspected
 Minimum of annual screening for STDs is
recommended, with more frequent screening if
high risk behaviors are reported
 Partner notification and risk reduction
counseling for both patient and partner is an
important part of treatment and follow-up.
38
Conclusion
 STD screening and treatment should be a
primary intervention and a standard of care in
all health care settings.
 Women infected with STDs have increased
chances of contracting HIV.
 Studies show STD and HIV co-infection
increases HIV virus shedding in the patients’
genital secretions.
 If co-infection is present, proper diagnosis and
treatment of STDs will decrease the chances
of transmitting HIV.
