Vaginal Discharge
Vaginal Discharge: Excerpt from In a Page: Signs and Symptoms
Vaginal discharge is a common complaint that is often accompanied by concerns about the presence of a sexually transmitted disease. Candida may present with extremely intense, often unbearable itch. Whenever one sexually transmitted disease is identified, a search for all other STDs is indicated in an effort to treat the individual patient as well as to prevent spread to others in the community or beyond. If an STD is identified, the patient should be encouraged to inform all sexual partners of the diagnosis.
Differential Diagnosis
- Physiologic
–Many women will have a consistent, slightly clear, non-odor-producing discharge, either midcycle or premenstrually, particularly if they are on oral contraceptives
–A change in odor, consistency, or color of discharge may signify that evaluation is necessary
–Increased discharge is associated with pregnancy
- Sexually transmitted disease
–Trichomonas vaginalis: “Strawberry cervix” with punctate erythema, flagellated oval organisms on wet mount
–Gonorrhea/Chlamydia may be associated with pelvic pain/dysmenorrhea and dyspareunia
- Bacterial vaginosis
–Various organisms and changes in normal flora with a characteristic fishy odor
–Not considered an STD
–Increases the risk of preterm delivery in
pregnant women
- Alteration of normal vaginal flora and/or inflammatory response
–Candida albicans overgrowth is more common with recent antibiotic use, poorly controlled diabetes, and/or pregnancy; presents with intensely pruritic, inflamed, and erythematous introitus
–Doderlein's cytolysis (caused by an
overgrowth of lactobacilli)
-
Atrophic vaginitis
–Common in postmenopausal women, especially those not on HRT
–Poor coital lubrication, dyspareunia
–Dysuria due to atrophic urethral tissue
-
Foreign body vaginitis (e.g., retained tampon)
-
Noninfectious irritant/allergic contact vaginitis (e.g., soaps, feminine pads, perfumes)
-
Cervicitis (usually due to gonorrhea or Chlamydia)
-
Cervical dysplasia, cancer, or polyps
-
Vaginal or vulvar trauma or cancer
Workup and Diagnosis
- A focused history and physical examination are crucial, including a complete sexual and exposure history, and full abdominal and pelvic examination
–A wet mount and KOH of the discharge are imperative
–pH of the discharge may aid in diagnosis
–A whiff test is done by smelling the discharge after KOH
is added; a positive test reveals a fishy odor characteristic of bacterial vaginosis
-
Initial labs may include CBC, urinalysis, urine culture, β-hCG, and gonorrhea and Chlamydia cultures
-
Test and treat for other STDs when one STD is found (HIV, hepatitis B and C, syphilis)
| pH | Discharge | Odor | Wet Mount |
|---|
|
| Trich >4.5 | yellow-green, copious | present | motile, flagellated |
| BV >4.5 | white-grey | fishy | clue cells |
| Candida <4.5 | white, curd-like | none | pseudo-hyphae |
| GC/chlamydia | mucopurulent | varies | PMNs |
|
| Atrophic vaginitis | thin, gray, watery | none | few epithelial cells |
