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

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.
