1. Very common
a) About 1/3 of vaginitis cases are caused by
fungal infection.
b) About 75% of women develop candidiasis at
least once in life.
2. The etiologic agent is Candida (假丝酵母菌/念珠菌).
Candida albicans (白假丝酵母菌) is responsible
for 80-90% of vulvovaginal candidiasis.
null3. Candida albicans is an opportunistic pathogen.
1) Suitable environment: acidic (<4.5), warm, and moist
2) Candida albicans can be isolated from 10-20%
nonpregnant and 30% pregnant asymptomatic women.Treatment is not indicated unless symptoms are present.
null Predisposing factors
1. Pregnancy
2. Diabetes mellitus
3. Immunosuppressants

null Pathogenesis
Two phases of candida albicans
1) Yeast spores (芽孢相):
Asymptomatic parasitism
2) Pseudohyphae (菌丝相):

3) Mechanism:
a) Candida at the pseudohypha phse penetrate vaginal
epithelium for nutrients
b) Growing candida albicans release proteolytic enzymes
and toxins etc. resulting in inflammation reaction

Points of note for treating VVC
Treatment should be followed-up with a premenstrual
examination of the vaginal discharge.
Approximately 10% of cases will not respond to
initial therapy.
Prolongation of treatment up to 14 days may cure
some patients.
