Efficacy of combined 5-nitroimidazole and probiotic therapy of bacterial vaginosis

The aim of the current research is to identify the clinical and microbiological effect of 5-nitroimidazol therapy for the treatment of bacterial vaginosis and in combination with probiotics and the influence of such therapy upon vaginal flora.

MATERIALS AND METHODS:
Women (n = 539) with bacterial vaginosis who meet the criteria were included in the study. They were randomized into two groups with the following therapeutic regimes: in the first group (n = 242 women) the treatment included applications of 2g BID tinidazole for two days and vaginal suppositories of 1000 mg metronidazol at day 1 and 3 (T+M). In the second group (n = 297) the women were cured with the same treatment as those in the first group. In addition to it from the fifth day of the treatment was added a topical administration of vaginal probiotic which contains species of alive lactobacilli: Lactobacillus acidophilus, Lactobacillus rhamnosus (T+M+P). The efficacy from the therapy was evaluated using the clinical compliances of the women, the data from the clinical examination and the microbiological tests results.

RESULTS:
The results showed expected increase of clinical therapy efficacy (Amsel - criteria) from 42.8% (T+M; n = 211/242) to 84.06% (T+M+P; n = 274/297) in groups and of microbiological efficacy (Nugent) from 44.7% (T+M; n = 211/242) to 83.3% (T+M+P; n = 274/297), in follow up 35-40 days from the beginning of treatment. The percentage of women with normal vaginal flora on 35-40 day after the therapy increase with 57% in the (T+M) first group while in the second group (T+M+P) with 94%.

CONCLUSIONS:
Combining the therapies of 5-nitroimidazoles and vaginal probiotic reduce bacterial vaginosis recurrence and restores permanently normal vaginal flora.

Prostate cancer and green tea, pomegranate, broccoli, and tumeric supplementation

Polyphenol-rich foods such as pomegranate, green tea, broccoli and turmeric have demonstrated anti-neoplastic effects in laboratory models involving angiogenesis, apoptosis and proliferation. Although some have been investigated in small, phase II studies, this combination has never been evaluated within an adequately powered randomised controlled trial.

In total, 199 men, average age 74 years, with localised prostate cancer, 60% managed with primary active surveillance (AS) or 40% with watchful waiting (WW) following previous interventions, were randomised (2:1) to receive an oral capsule containing a blend of pomegranate, green tea, broccoli and turmeric, or an identical placebo for 6 months.

[]The median rise in PSA in the food supplement group (FSG) was 14.7% as opposed to 78.5% in the placebo group a difference of 63.8% (P=0.0008). In all, 8.2% of men in the FSG and 27.7% in the PG opted to leave surveillance at the end of the intervention (P=0.014). There were no significant differences within the predetermined subgroups of age, Gleason grade, treatment category or body mass index. There were no differences in cholesterol, blood pressure, blood sugar, C-reactive protein or adverse events.

This study found a significant short-term, favourable effect on the percentage rise in PSA in men managed with AS and WW following ingestion of this well-tolerated, specific blend of concentrated foods. Its influence on decision-making suggests that this intervention is clinically meaningful, but further trials will evaluate longer term clinical effects, and other makers of disease progression.
