II. Epidemiology

  1. Candida Vulvovaginitis accounts for 45% of Vaginitis
  2. Candida is cultured in 20-50% asymptomatic women
  3. Vaginitis often self diagnosed incorrectly

III. Etiology

  1. Acute: Candida albicans (90%)
    1. Normal commensal organism in vagina
    2. Infection when Corynebacterium suppressed
  2. Recurrent Vulvovaginal Candidiasis (4 or more episodes in a year)
    1. Candida glabrata (increasing Incidence, now 15%)
    2. Candida tropicalis
    3. Candida parapsilosis
    4. Candida krusei (responds to Topical Antifungals, but not to Fluconazole)
    5. Saccharomyces cerevisiae

IV. Risk Factors

  1. Immunosuppression
    1. Diabetes Mellitus (esp. Uncontrolled)
    2. Depressed cell mediated Immunity (e.g. HIV or AIDS)
  2. Medications
    1. Corticosteroids
    2. Immunosuppressant Medications
    3. Broad spectrum antibiotics
    4. Oral Contraceptives
      1. Increases frequency of Candida carrier state
      2. Does not increase symptomatic Vulvovaginitis
  3. Heat and moisture retaining clothing (e.g. nylon)
  4. Pregnancy (and other hyperestrogenic states)
  5. Premenstrual phase of the Menstrual Cycle
  6. Obesity

V. Symptoms

  1. Asymptomatic in 20-50% of women
  2. Intense vaginal or Vulvar Pruritus (50% of cases)
  3. Vulvar Burning, soreness, or irritation
  4. Thick white curd-like or "cottage cheese" discharge
  5. No odor
  6. Dyspareunia
  7. Dysuria (33% of cases)

VI. Signs

  1. Adherent white cottage-cheese discharge in vagina
    1. Sensitivity: 50%
    2. Specificity: 90%
  2. Vulvar erythema and edema (24% of cases)

VII. Labs: Initial

  1. KOH Preparation (10%)
    1. Test Sensitivity: 50%
    2. Pseudohyphae or budding yeast forms
    3. GynVaginitisYeast.jpg
  2. Vaginal pH <4.5 (Normal acidity)
  3. Absent Amine odor
  4. White Blood Cells not increased
  5. Wet-Prep is not sensitive or specific for yeast
    1. Bornstein (2001) Infect Dis Obstet Gynecol 9:105-11 [PubMed]

VIII. Labs: Complicated cases

  1. Indications: Complicated Vulvovaginal Candidiasis
    1. Recurrent candida Vaginitis (4 or more episodes in a year) OR
    2. Severe candida infections OR
    3. Immunocompromised patients (AIDS, poorly controlled Diabetes Mellitus)
  2. Fungal Culture positive
    1. Fungal Culture is rarely performed in typical cases (fungal PCR preferred)
    2. Fungal Culture may be very helpful in complicated cases
      1. Confirm asymptomatic carrier of vaginal Candida
      2. Identify cause of recurrent Vaginitis
  3. DNA probe or PCR for candida
    1. Consider in cases refractory to standard therapy

IX. Differential Diagnosis (Consider for refractory cases)

  1. Other Vaginitis cause
    1. Bacterial Vaginosis
    2. TrichomonasVaginitis
  2. Infectious Cervicitis (Sexually Transmitted Disease)
  3. Allergic Vaginitis or Vulvitis
  4. Vulvodynia
  5. Herpes Simplex Virus
    1. HSV presents with unilateral painful lesions
    2. Contrast with bilateral, symmetric involvement in Candida Vulvovaginitis
