Overview

Vaginitis is a common problem in women. Candida albicans is responsible for more than 85% of vaginal fungal infections. The aim of this study was to compare the effects of probiotic and fluconazole on the treatment and recurrence of vulvovaginal candidiasis (VVC). This triple-blinded randomized controlled trial was conducted on 80 married women, aged 18–49 years, with VVC, as confirmed by clinical and laboratory diagnosis. The participants were allocated into two groups using blocked randomization method. The fluconazole-treated group received a single dose of fluconazole (150 mg) supplemented with 30 placebo capsules of probiotic, and the probiotic-treated group got 30 probiotic capsules containing 1 × 10 9  CFU/g LA-5 with 1 fluconazole placebo capsule. The samples were taken from patients to evaluate the vaginal pH and microbiological tests before, 30–35 days, and 60–65 days after starting the treatment. The signs and symptoms were assessed before the intervention and the first and second follow-ups. Chi-square, Fisher’s exact, independent t , and ANCOVA tests were then used for data analysis. There was no statistically significant difference between the two groups ( p  = 0.127) in the frequency of negative culture 30–35 days after starting the treatment, but the frequency of negative culture 60–65 days after starting treatment in the fluconazole group was significantly higher than that of the probiotic group ( p  = 0.016). The abnormal discharge and vulvovaginal erythema in the first and second follow-ups and also pruritus in the second follow-up in the fluconazole group were significantly lower than those in the probiotic group ( p  < 0.05). There was, however, no statistically significant difference in burning, frequent urination, dysuria, and dyspareunia between the groups ( p  > 0.05). Lactobacillus acidophilus supplementation had an effect similar to that of fluconazole in treating most symptoms of VVC, but it was less effective than the latter in preventing recurrence.
