The document provides treatment guidelines for several sexually transmitted infections (STIs): - Chancroid is diagnosed based on painful genital ulcers and lymphadenopathy. It is treated with azithromycin, ceftriaxone, ciprofloxacin, or erythromycin. - Herpes is typically treated with acyclovir, valacyclovir, or famciclovir for suppressive or episodic therapy. Pregnant women may take acyclovir or valacyclovir. - Syphilis treatment depends on stage, and involves benzathine penicillin for most cases.

Chancroid
• The combination of a painful genital ulcer and tender
suppurative inguinal adenopathy suggests the diagnosis of
chancroid
1) the patient has one or more painful genital ulcers;
2) the clinical presentation, appearance of genital ulcers and, if
present, regional lymphadenopathy are typical for chancroid;
3) the patient has no evidence of T. pallidum infection by
darkfield examination of ulcer exudate or by a serologic test for
syphilis performed at least 7 days after onset of ulcers; and
4) an HSV PCR test or HSV culture performed on the ulcer
exudate is negative

Suppressivetherapyof a pregnantwomen
Recommended regimenfor suppressive therapy of pregnant
women with recurrent genital herpes *
Acyclovir 400 mg orally three times a day
OR
Valacyclovir 500 mg orally twice a day
* Treatment recommended starting at 36 weeks of gestation
GranulomaInguinale(Donovanosis)
• Painless, slowly progressive ulcerative lesions on the genitals or
perineum without regional lymphadenopathy; subcutaneous
granulomas (pseudobuboes) also might occur.
• The lesions are highly vascular (i.e., beefy red appearance) and
bleed.
• Extragenitalinfection can occur with extension of infection to
the pelvis, or it can disseminate to intra-abdominal organs,
bones, or the mouth.
• The lesions also can develop secondary bacterial infection and
can coexist with other sexually transmitted pathogens.
• Diagnosis requires visualization of dark-staining Donovan
bodies on tissue crush preparation or biopsy.
RecommendedRegimen
Azithromycin 1 g orally once per week or 500 mg daily for at least 3
weeks and until all lesions have completely healed
Alternative Regimens
Doxycycline 100 mg orally twice a day for at least 3 weeks and until all
lesions have completely healed
OR
Ciprofloxacin 750 mg orally twice a day for at least 3 weeks and until all
lesions have completely healed

and until all lesions have completely healed
OR
Trimethoprim-sulfamethoxazole one double-strength (160 mg/800 mg)
tablet orally twice a day for at least 3 weeks and until all lesions have
completely healed
LymphogranulomaVenereum
• tender inguinal and/or femoral lymphadenopathy that is
typicallyunilateral.
• A self-limited genital ulcer or papule sometimes occurs at the
site of inculation.
• Genital lesions, rectal specimens, and lymph node specimens
(i.e., lesion swab or bubo aspirate) can be tested for C.
trachomatis by culture, direct immunofluorescence, or nucleic
acid detection
• Chlamydia serology (complement fixation titers ≥1:64 or
microimmunofluorescencetiters >1:256) might support the
diagnosis of LGV
Recommended Regimen
Doxycycline 100 mg orally twice a day for 21 days
Alternative Regimen
Erythromycin base 500 mg orally four times a day for 21 days
Syphilis
• Persons who have syphilis might seek treatment for signs or
symptoms of primary syphilis infection (i.e., ulcers or chancre
at the infection site),
• secondary syphilis (i.e., manifestations that include, but are not
limited to, skin rash, mucocutaneous lesions, and
lymphadenopathy), or
• tertiary syphilis (i.e., cardiac, gummatous lesions, tabes
dorsalis, and general paresis).
• Darkfield examinations and tests to detect T. pallidum directly
from lesion exudate or tissue are the definitive methods for
diagnosing early syphilis.

by testing first-catch urine or collecting swab specimens from
the endocervix or vagina.

GonococcalInfections
• Culture and NAAT are available for the detection of
genitourinary infection with N. gonorrhoeae (394); culture
requires endocervical (women) or urethral (men) swab
specimens
• Detection of infection using Gram stain of endocervical,
pharyngeal, and rectal specimens also is insufficient and is not
recommended. MB/GV stain of urethral secretions is an
alternative point-of-care diagnostic test with performance
characteristics similar to Gram stain.
• Presumed gonococcal infection is established by documenting
the presence of WBC containing intracellular purple diplococci
in MB/GV smears.

BacterialVaginosis
• anaerobic bacteria (e.g., Prevotella sp. and Mobiluncus sp.), G.
vaginalis, Ureaplasma, Mycoplasma, and numerous fastidious
or uncultivated anaerobes.
• Gram stain (considered the gold standard laboratory method
for diagnosing BV) is used to determine the relative
concentration of lactobacilli (i.e., long Gram-positive rods),
Gram-negative and Gram-variable rods and cocci (i.e., G.
vaginalis, Prevotella, Porphyromonas, and peptostreptococci),
and curved Gram-negative rods (i.e., Mobiluncus) characteristic
of BV.
Clinical criteria require three of the following symptoms or signs:
• homogeneous, thin, white discharge that smoothly coats the
vaginal walls;
• clue cells (e.g., vaginal epithelial cells studded with adherent
coccoobacilli) on microscopic examination;
• pH of vaginal fluid >4.5; or

KOH (i.e., the whiff test).

• presence of abundant numbers of WBC on saline microscopy of
vaginal fluid;

• PID is bilateral
• Ectopic pregnancy
• Always do a pregnancy test
• Urinary tract infection or stone
• “Ovarian cysts”
• Lower genital tract infection
PID Sequelae
• Chronic Pelvic Pain (15-20 %)
• Ectopic pregnancy (6-10 fold ↑Risk)
• At least 50% of tubal pregnancies have histology
of PID
• Infertility (Tubal)
• 10 – 15% after one episode
