Candida Glabrata Infection Characteristics

Clinical Presentation

The characteristic presentation of C. glabrata vulvovaginitis includes white adherent vaginal discharge, burning, itching, vulvar edema, erythema, excoriation, and fissures, but bleeding is not described as a typical feature, according to the Infectious Diseases Society of America 1, 2, 3, 4
White, thick, adherent vaginal discharge (not bloody discharge) is a common symptom of C. glabrata vulvovaginitis, as noted by the European Society of Clinical Microbiology and Infectious Diseases 1, 2
Burning and itching are primary symptoms of C. glabrata vulvovaginitis, as reported by the Centers for Disease Control and Prevention 1, 2
Vulvar edema, erythema, and excoriation on examination are typical findings in C. glabrata vulvovaginitis, according to the American College of Obstetricians and Gynecologists 3, 4
Fissures may develop in severe cases of C. glabrata vulvovaginitis, as noted by the Infectious Diseases Society of America 3, 4

The infection remains confined to mucosal surfaces in immunocompetent women, as reported by the European Society of Clinical Microbiology and Infectious Diseases 1, 2
Confirm diagnosis with wet-mount preparation using saline and 10% potassium hydroxide, as recommended by the Centers for Disease Control and Prevention 3, 4
Verify normal vaginal pH (4.0-4.5)—elevated pH suggests bacterial vaginosis or trichomoniasis, according to the American College of Obstetricians and Gynecologists 3, 5
Obtain vaginal cultures if microscopy is negative, as C. glabrata doesn't form pseudohyphae or hyphae, making microscopic identification difficult, as noted by the Infectious Diseases Society of America 6
Perform pelvic examination to identify sources of bleeding (cervical, vaginal wall trauma, other pathology), as recommended by the American College of Obstetricians and Gynecologists 3, 4

If vaginal bleeding is present, consider alternative diagnoses such as cervical pathology (cervicitis, cervical cancer, polyps), as recommended by the American College of Obstetricians and Gynecologists 6
Endometrial pathology (endometritis, endometrial cancer, polyps) should also be considered in the presence of vaginal bleeding, according to the Infectious Diseases Society of America 6
Trauma or fissures (though fissures from C. glabrata would cause spotting at most, not frank bleeding) may also cause vaginal bleeding, as noted by the Centers for Disease Control and Prevention 3
Coexisting sexually transmitted infections should be considered in the presence of vaginal bleeding, as recommended by the American College of Obstetricians and Gynecologists 6
Hormonal causes (breakthrough bleeding, anovulation) may also contribute to vaginal bleeding, according to the Infectious Diseases Society of America 6

In severely immunocompromised patients, C. glabrata vaginal colonization combined with systemic symptoms warrants urgent evaluation for disseminated candidiasis, as recommended by the Infectious Diseases Society of America 7
Disseminated disease can present with hemorrhagic skin lesions (discrete pink to red papules with potential hemorrhagic transformation if thrombocytopenia present), according to the Centers for Disease Control and Prevention 7
High fever and poor general condition are also indicative of disseminated candidiasis in immunocompromised patients, as noted by the American College of Obstetricians and Gynecologists 7
This represents a life-threatening emergency requiring skin biopsy, blood cultures, and systemic antifungal therapy with echinocandins, as recommended by the Infectious Diseases Society of America 7

Candida glabrata vulvovaginitis characteristically causes burning, intense itching, vulvar edema, erythema, excoriation, and fissures, leading to dyspareunia and painful urination (external dysuria)【8】.
Burning sensation involves both vulvar and vaginal tissues, reflecting inflammatory irritation【8】.
External dysuria arises when urine contacts inflamed vulvar tissue, producing discomfort during voiding【8】.
Dyspareunia is a common reason women seek care for this infection【8】.

Vulvar edema and erythema create tissue tension and heightened sensitivity【8】.
Excoriation from scratching produces raw, painful areas on the vulva【8】.
Fissures may develop in severe cases, causing sharp pain especially during intercourse or urination【8】.
A white, thick, adherent vaginal discharge often accompanies these painful symptoms【8】.

C. glabrata accounts for approximately 10–20 % of recurrent vulvovaginal candidiasis cases and is linked to higher treatment‑failure rates compared with C. albicans infections【9】.

Vaginal pH is typically normal (4.0–4.5); an elevated pH suggests alternative diagnoses such as bacterial vaginosis or trichomoniasis【8】.
The organism does not form pseudohyphae or hyphae, making microscopic identification difficult; definitive diagnosis requires vaginal culture【8】【9】.
Because symptoms are nonspecific, confirmation with a wet‑mount preparation using saline and 10 % potassium hydroxide is recommended before initiating therapy【8】.

Intravaginal boric acid 600 mg daily for 14 days is the first‑line option for azole‑unresponsive C. glabrata vulvovaginitis【8】.
Nystatin intravaginal suppositories 100,000 units daily for 14 days serve as an effective alternative【8】.
Topical 17 % flucytosine cream alone or combined with 3 % amphotericin B cream for 14 days is a third therapeutic option【8】.

The required treatment course for C. glabrata (14 days) is considerably longer than that for uncomplicated C. albicans infections (1–3 days), resulting in a prolonged period of painful symptoms before resolution【8】【10】.
