Background
- Local fungal infection caused by the Candida genus (most commonly Candida albicans)
- Most commonly seen in females in high estrogen states: pregnancy, oral contraceptive use, obesity, diabetes mellitus
- Not considered an STI although it can be transmitted by sexual intercourse
- May occur in premarnarcheal girls (rare)
- Can occur as a result of antibiotic use
Types[1]
- Uncomplicated (must have all)
- Sporadic infection
- Mild-moderate symptoms
- Due to Candida albicans (suspected or proven)
- Immunocompetent
- Complicated (presence of ANY of the following)
- Any species other than C. albicans
- Recurrent infection (defined as ≥4 episodes per year)
- Severe symptoms or findings
- Poorly controlled diabetes, immunocompromising conditions (such as HIV), debilitation, or immunosuppressive therapy (e.g., corticosteroids)
Clinical Features
- Vulvar pruritus - most common and specific symptom[2]
- Vaginal discharge - varies from little to copious and from watery to cottage-cheese like
- Malodorous smell is unusual (if present favors diagnosis of Bacterial vaginosis)
- Intense vulvovaginal pruritus or burning
- Dyspareunia
- Dysuria
Differential Diagnosis
Vulvovaginitis
- Bacterial vaginosis
- Candida vaginitis
- Trichomonas vaginalis
- Contact vulvovaginitis
- Bubble baths and soaps
- Deodorants, powders, and douches
- Clothing
- Atrophic vaginitis due to lack of estrogen (AKA Vulvovaginal atrophy)
- Lichen sclerosus
- Tinea cruris
- Chlamydia/Gonorrhea infection
- Pinworms
- Vaginal foreign body
- Toilet paper
- Other
- Genitourinary syndrome of menopause
- Foreign body
- Allergic reaction
- Normal physiologic discharge
Evaluation
Work-up
- Urine pregnancy
- Wet mount
- Consider blood glucose (if recurrent, to check for occult DM)
- Consider tests for STIs
Diagnosis
- Cotton cheese curd-like non-odorous vaginal discharge on pelvic exam
- Vaginal pH < 4.5
- Vaginal wet mount
- Hyphae and yeast buds
- Candida does not cause WBCs on wet mount → if present, consider co-infection with other vaginitides or STI
Management
- Do not treat if asymptomatic
- Sexual partners should not be treated unless the patient has frequent recurrences
- Does not need a test of cure
Antifungals
Uncomplicated
There is little resistance to azole medications; treatment often dictated by patient preference.
- Fluconazole 150mg PO once (preferred)[3]
- A second dose at 72hrs may be given if patient is still symptomatic
- Intravaginal therapy
- Clotrimazole 1 % cream applied vaginally for 7 days OR
- Clotrimazole 2% applied vaginally for 3 days
- Miconazole 2% cream applied vaginally for 7 days OR 4% cream x 3 days
- Butoconazole 2% applied vaginally x 3 days
- Tioconazole 6.5% applied vaginally x 1
Complicated
Severe or immunosuppressed
- Fluconazole 150mg PO q72h x 3 doses
Non-albicans species
- For example, C. glabrata, C. krusei and other atypical Candida spp.
- Boric acid vaginal suppository intravaginal qday x ≥14 days
- Can be fatal if taken orally
- If empirically treated and later is found to have non-albicans Candida spp., no change in therapy is needed if patient is improving (otherwise switch to boric acid.
Recurrent (≥ 4 infections in a year)
- Treat as for uncomplicated (see above)
- Once therapy completed, prescribe long-term treatment
- Fluconazole 150mg PO qweek x 6 months, OR
- Intravaginal medication, such as clotrimazole 500mg PV qweek or 200mg PV twice a week
Pregnant Patients
- Intravaginal clotrimazole or miconazole are the only recommended treatments
- Duration is 7 days
- PO fluconazole associated with congenital malformations and spontaneous abortions[4]
Disposition
- Outpatient
- Refer all "complicated" cases to gynecology
