The aim of the present study was to assess the clinical efficacy of a one week/month treatment with a phytocompound with antimycotic properties (K-712, with following 100 mg composition: 10 mg of oleoresin from Pseudowintera colorata at 30% concentration in Polygodial together with trace amounts of Olea europea) in recurrent vulvo-vaginal candidiasis (RVVC), as compared to once a week treatment with an azole drug for 24 months follow up. This prospective randomized study involving 122 women (19 to 63 years old) with a history of proven episodes of RVVC in the prior 12 months. Patients were allocated in two treatment groups of 61 patients each and given A) Itraconazole 200 mg orally once a week or B) 1 tab twice a day of K-712 for one week/month. Each treatment schedule was well tolerated with 19 patients in the azole group complaining of transient mild symptoms (nausea, abdominal discomfort, unpleasant taste), while only 3 patients on K-712 reported slight dyspepsia. The number of relapses was significantly lower in the K-712-treated group as compared to the itraconazole-group (22 vs 39, p<0.05). Moreover, the former group showed a significantly decreased number of cases resistant or dose-dependent susceptible as compared to group A (p<0.05 vs itraconazole) and the same occurred for the occurrence of non-albicans species (group A 64.1% vs group B 31.8%, p<0.05). The overall mycological cure at the end of the 2-year study showed a comparable benefit between the two groups. From these data it appears that the present antifungal phytonutrient is equally effective as itraconazole in the overall treatment of RVVC over a 2-year follow-up, but yielding a significantly better prophylactic effect and also maintenance benefit with lower relapse rate, antifungal susceptibility and growth of azole-resistant species.

The aim of the present study is to assess the clinical efficacy of a phytocompound with antimicotic properties (K-712, with the following 100 mg composition: 10 mg of oleoresin from Pseudowintera colorata at 30% concentration in Polygodial together with trace amounts of Olea europea) in recurrent vulvo-vaginal candidiasis (RVVC) as compared to an azole drug during a 12-month period: 6 months of treatment followed by 6 months of observation. This prospective randomized study involved 82 women (19-61 years) with complaints of abnormal vaginal discharge and with a history of at least four proven episodes of RVVC in the previous 12 months. Patients were divided into two groups of treatment of 41 patients each and were given: A) Itraconazole 200 mg orally daily for 4 days, then 200 mg once weekly for 6 months or B) 1 tablet twice a day of a K-712 for 4 weeks and then for the first 2 weeks of each month for a total of 6 months. Both groups were then followed-up for further 6 months. Each treatment schedule was well tolerated with only 4 patients in the azole group complaining of transient mild symptoms (nausea, abdominal discomfort, unpleasant taste). Itraconazole reached an earlier symptomatic relief during the first two weeks of observation as compared with K-712 (p<0.05) but both treatments enabled a comparable benefit during the entire treatment study period, afterwards with comparable symptom/sign score (itraconazole vs K-712: 9 vs 11). At 6-month observation, mycological cure was reached by 83% in the itraconazole group and in 78% of the K-712-treated patients. During the further 6-month observation period without treatment, the itraconazole group showed significantly more relapses (65.7 vs 34.2 in K-712, p<0.05) and at the end of the whole 12-month study period the mycological cure was significantly higher in the K-712-treated patients (65.8.% vs 34.3%, p<0.05). There was a non- significant trend increase of less drug-susceptible species in the itraconazole group. From these preliminary data it would appear that a natural antifungal phytocompound proves to be as good as itraconazole in the maintenance treatment of RVVC. Moreover, this approach seems to maintain a higher mycological success rate afterwards by reducing the number of relapses and probably of the growth of azole-resistant species.
