No safe and convenient regimen has proved to be effective for the management of recurrent vulvovaginal candidiasis. After inducing clinical remission with open-label fluconazole given in three 150-mg doses at 72-hour intervals, we randomly assigned 387 women with recurrent vulvovaginal candidiasis to receive treatment with fluconazole (150 mg) or placebo weekly for six months, followed by six months of observation without therapy. The primary outcome measure was the proportion of women in clinical remission at the end of the first six-month period. Secondary efficacy measures were the clinical outcome at 12 months, vaginal mycologic status, and time to recurrence on the basis of Kaplan–Meier analysis. Weekly treatment with fluconazole was effective in preventing symptomatic vulvovaginal candidiasis. The proportions of women who remained disease-free at 6, 9, and 12 months in the fluconazole group were 90.8 percent, 73.2 percent, and 42.9 percent, as compared with 35.9 percent, 27.8 percent, and 21.9 percent, respectively, in the placebo group (P< 0.001). The median time to clinical recurrence in the fluconazole group was 10.2 months, as compared with 4.0 months in the placebo group (P<0.001). There was no evidence of fluconazole resistance in isolates of Candida albicans or of superinfection with C. glabrata. Fluconazole was discontinued in one patient because of headache. Long-term weekly treatment with fluconazole can reduce the rate of recurrence of symptomatic vulvovaginal candidiasis. However, a long-term cure remains difficult to achieve.

Vulvovaginal candidiasis (VVC) is a common infection affecting women worldwide. Reports of patterns/risk factors/trends for episodic/recurrent VVC (RVVC) are largely outdated. The purpose of this study was to obtain current patient perspectives of several aspects of VVC/RVVC. Business cards containing on-line survey information were distributed to healthy volunteers and patients seeking standard, elective, or referral gynecologic care in university-affiliated Obstetrics/Gynecology clinics. The internet-based questionnaire was completed by 284 non-pregnant women (78% Caucasian, 14% African American, 8% Asian). The majority of the participants (78%) indicated a history of VVC with 34% defined as having RVVC. The most common signs/symptoms experienced were itching, burning and redness with similar ranking of symptoms among VVC and RVVC patients. Among risk factors, antibiotic use ranked highest followed by intercourse, humid weather and use of feminine hygiene products. A high number of respondents noted ‘no known cause’ (idiopathic episodes) that was surprisingly similar among women with a history of either VVC or RVVC. VVC/RVVC episodes reported were primarily physician-diagnosed (73%) with the remainder mostly reporting self-diagnosis and treating with over-the-counter (OTC) medications. Most physician-diagnosed attacks utilized a combination of pelvic examination and laboratory tests followed by prescribed antifungals. Physician-treated cases achieved a higher level of symptom relief (84%) compared to those who self-medicated (57%). The majority of women with RVVC (71%) required continual or long-term antifungal medication as maintenance therapy to control symptoms. Current patient perspectives closely reflect historically documented estimates of VVC/RVVC prevalence and trends regarding symptomatology, disease management and post-treatment outcomes.

Candiduria is rarely present in healthy individuals. In contrast, it is a common finding in hospitalized patients, especially those in intensive care units (ICUs) who often have multiple predisposing factors, including diabetes mellitus, indwelling urinary catheters, and exposure to antimicrobials. Candiduria occurs much less commonly in the community setting. In a majority of episodes in adult patients in critical care facilities candiduria represents colonization, and antifungal therapy is not required. However, the presence of yeast in the urine can be a sign of a disseminated infection. In the critically ill newborn, candiduria often reflects disseminated candidiasis and is accompanied by obstructing fungus ball formation in the urinary tract. In ICU patients, although candiduria is a marker for increased mortality, it is only rarely attributable to Candida urinary tract infection.
