“…3,14 Similarly to our results, Brumar et al 7 also reported a high cure rate with fluconazole (85.71%) in diabetic women with VVC. We acknowledge that the number of diabetic women in our study was small, and that this group may not fully represent populations of diabetic women.…”

CONTEXT AND OBJECTIVE: Vulvovaginal candidiasis (VVC) is caused by abnormal growth of yeast-like fungi on the female genital tract mucosa. Patients with diabetes mellitus (DM) are more susceptible to fungal infections, including those caused by species of Candida. The present study investigated the frequency of total isolation of vaginal Candida spp., and its different clinical profiles -colonization, VVC and recurrent VVC (RVVC) -in women with DM type 2, compared with non-diabetic women. The cure rate using fluconazole treatment was also evaluated. DESIGN AND SETTING: Cross-sectional study conducted in the public healthcare system of Maringá, Paraná, Brazil. METHODS:The study involved 717 women aged 17-74 years, of whom 48 (6.7%) had DM type 2 (mean age: 53.7 years), regardless of signs and symptoms of VVC. The yeasts were isolated and identified using classical phenotypic methods. RESULTS:In the non-diabetic group (controls), total vaginal yeast isolation occurred in 79 (11.8%) women, and in the diabetic group in 9 (18.8%) (P = 0.000). The diabetic group showed more symptomatic (VVC + RVVC = 66.66%) than colonized (33.33%) women, and showed significantly more colonization, VVC and RVVC than seen among the controls. The mean cure rate using fluconazole was 75.0% in the diabetic group and 86.7% in the control group (P = 0.51). CONCLUSION: We found that DM type 2 in Brazilian women was associated with yeast colonization, VVC and RVVC, and similar isolation rates for C. albicans and non-albicans species. Good cure rates were obtained using fluconazole in both groups. RESUMO

“…As far as the constituents that are probably responsible for the antifungal effects are concerned, they are comparable with propolis samples originating from other countries reported in the literature [20][21][22][23][24][25][26][27][28][29][30][31][32]. Future research of propolis is needed, particularly in the field of isolation and detailed description of its biologically active compounds.…”

“…The inhibitory effect of propolis on pathogenic fungi, including yeasts and dermatophytes, have been described by many investigators [6,20,22,26,27]. Most of these experiments tested propolis as ethanolic extract (EEP), so it was difficult to specify a component responsible for a specific antifungal effect except for flavonoids.…”

Propolis has been used in traditional folk medicine for ages owing to a number of biological effects. Four propolis samples of Czech and one of Slovak origin were extracted using Soxhlet apparatus and analysed by thin-layer chromatography. Raw propolis samples and their extracts were tested by microdilution broth method to determine minimal inhibitory concentration (MIC) in eight strains of human pathogenic fungi. Raw propolis samples showed a lower in vitro antifungal activity than their extracts. In general, the petroleum ether extracts exhibited the highest in vitro antifungal activity (MIC range of 16-64 µg/ml). The content of flavonoids in the samples varied according to region. The highest amount of flavonoids was found in sample A that originated from Broumov (4%). The most susceptible to the propolis extracts were Trichophyton mentagrophytes and Candida albicans. The propolis samples of Czech and Slovak origin and their extracts showed a considerable in vitro antifungal effect which was associated especially with nonpolar petroleum ether and toluene extracts. There was only a partial correlation between flavonoids content and in vitro antifungal activity.

Extratos etanólicos de própolis obtidos a partir de diferentes concentrações de própolis e com álcool hidratado com diferentes teores de álcool/água foram analisados. A ação antioxidante destes extratos foi determinada através da captura do radical livre 1,1-difenil-2-picril-hidrazila (DPPH•) e do poder de redução férrico (FRAP) utilizando o complexo férrico-tripiridiltriazina (Fe 3+ -TPTZ). O teor de compostos fenólicos totais e a quantificação de flavonóides também foram verificados e obtidos por espectrometria de massas com ionização por electrospray (ESI(-)-MS) dos extratos. Observou-se que a composição química dos extratos de própolis e sua atividade antioxidante variam com a concentração de própolis e, principalmente, com o teor de álcool/água do etanol hidratado utilizado na extração. Foi possível perceber também que a atividade antioxidante dos extratos é significativamente dependente destes parâmetros de extração e que as composições de compostos fenólicos e flavonóides também variam muito. Os valores de FRAP não apresentaram, porém, boa correlação com o teor de flavonóides.Ethanolic extracts of propolis obtained with different concentrations of propolis and made using hydrous ethanol with various water/ethanol contents were analyzed. The antioxidant action of the extracts was determined by free radical 1,1-diphenyl-2-picryl-hydrazyl (DPPH•) scavenging and by ferric reducing ability power (FRAP), using the ferric-tripyridyl triazine (Fe 3+ -TPTZ) complex. The total phenolic and flavonoid contents were also determined, and the electrospray ionization mass spectrometry spectra (ESI(-)-MS) of the extracts were acquired. The chemical composition of propolis extracts and their antioxidant activity were observed to vary with the concentration of propolis, and especially with the water/ethanol contents of the hydrous ethanol used for extraction. The antioxidant activity of the extracts was also found to be significantly dependent on these extraction parameters, as well as on the composition of the phenolic compounds and flavonoids. FRAP values showed, however, poor correlation with the flavonoid content.
