sodium-bicarbonate and Candidiasis--Oral

This study aimed at evaluating the short-term efficacy and safety of probiotics as an aid in the treatment of Candida-associated stomatitis in a randomised controlled trial. A total of 65 patients were randomly assigned to receive oral local antifungal agents alone (gargle 2% sodium bicarbonate solution for 30 s, wait 10 min and then apply 2% nystatin paste) or these agents plus local probiotics (the mixture of Bifidobacterium longum, Lactobacillus bulgaricus and Streptococcus thermophilus) three times per day for 4 weeks. Parameters related to hyperaemia, visual analogue scale scores, culture of resting saliva and a lingual dorsum swab and adverse reactions were assessed or recorded in the beginning, middle and end of treatment. Although the baseline characteristics of the participants were similar, both groups showed a significant reduction in pain level and hyperaemia on the tongue mucosa (P = 0.000) after 4-week application. However, despite the reduction in hyperaemia in the probiotic group, these improvements did not display statistically significant differences. The detection rate of Candida spp. was 100% before treatment and 8.21% in the experimental group and 34.6% in the control group after treatment. The detection rate of Candida spp. decreased (P = 0.000) in both groups and was significantly lower in the probiotic group than the control group (P = 0.038). Other analysed micro-organisms, including the decreased detection rate for Lactobacillus spp. (P = 0.049) and the increased detection rate for Staphylococcus epidermidis (P = 0.019), did not display consistent change trends in the probiotics group. Compared with conventional antifungal therapies for oral candidiasis, the inclusion of locally administered probiotics helped improve certain clinical conditions and reduced the prevalence of Candida spp., although the impact of probiotics on oral bacterial species remains to be further studied.

This article deals with the 0.06/1000 allicin and 2.5% sodium bicarbonate in order to look for effective drugs in preventing thrush. The results revealed: (1) The incidence of the disease of the two drugs in the less dangerous group was significantly decreased compared with that of the control (P less than 0.01); (2) In the more dangerous group, the incidence of the disease of the allium group was more significantly decreased than that of the control, but no significant decrease in sodium bicarbonate was observed. The two drugs are both effective in preventing thrush and the allium is more effective.

Relevant reports about oral candidiasis status and prevention measures after free flap surgery for the oral and maxillofacial region are limited. The present study explored oral candidiasis status after free flap surgery and its prevention through a prospective comparative study.. One hundred four patients were randomized to a control group (n = 54) and an experimental group (n = 50). Compared with the control group, the experimental group was provided an additional 3% sodium bicarbonate saline solution for oral care after free flap surgery. The incidence of oral candidiasis was evaluated by objective examination (saliva culture and salivary pH measurement) and subjective evaluation (clinical signs of oral candidiasis) at admission and from postoperative days 1 to 14.. The salivary pH values of the 2 groups were lower than the normal salivary pH, and postoperative salivary pH values were always lower than the active range of oral lysozymes in the control group. The salivary pH values of the experimental group were higher than those of the control group from postoperative days 6 to 14 (P < .05). The incidence of oral candidiasis was 13.0% in the control group, which was higher than that in the experimental group (2.0%; P < .05). In addition, advanced age, use of a free flap for the simultaneous repair of intraoral and paraoral defects, and a combination of 2 antibiotic types were risk factors for oral candidiasis.. Oral candidiasis was common in patients after free flap reconstruction surgery, and the use of 3% sodium bicarbonate saline solution for oral care effectively prevented it.

Establishment of an effective prophylaxis against oral candidiasis by local treatment is essential for immunocompromised patients. The aim of the study is to assess effectiveness and stability of antifungal suspensions for mouthrinses. The assessed suspensions are compounded by one solvent among sterile water, spring water or sodium bicarbonate associated with amphotericin B (Fungizone®) or nystatine (Mycostatine®). Two others mixes are assessed: Mycostatine®-bicarbonate and Mycostatine®-Hextril®-bicarbonate as well as the two straight antifungal. In vitro activity is tested on five Candida species (C. albicans, C. glabrata, C. krusei, C. parapsilosis, C. tropicalis) after a five minutes contact between yeasts and the assessed suspension. A galenic study is realized during 3 days. Mixes associating a polyene with sodium bicarbonate have no effectiveness on Candida albicans, others mixes shows intermediate effectiveness (the percentage of yeast growth inhibition lies between 35% and 68%). Effectiveness results of Hextril®-based mixes are not explainable because of alcohol in its composition. Spring water-based mixes must be evicted due to microbiologic contaminations after 48hours. Mycostatine®-Hextril®-bicarbonate mix is not stable during 3 days. All those mouthrinses, poorly effective, excepted on C. glabrata, should be avoided. Straight Mycostatine® shows a good antifungal effectiveness excepted on C. krusei and its use should be recommended.

Amphotericin B and nystatin are two polyene antibiotics that are potent antifungal agents. These drugs are active against most pathogenic fungi like Aspergillus and Candida. Mouthrinses containing these drugs are used for preventive and curative treatment of fungal infections like oral candidiasis, which can cause multiple diseases in cancer patients. Because there were no marketed antifungal mouthrinses available, their preparations were performed at the hospital and town pharmacies. To date, there are no data available on the stability of both these drugs in the form of mouthrinses. Therefore, each mouthrinse had to be prepared extemporaneously. The aim of this study was to investigate the stability of amphotericin B (Fungizone) and nystatin (Mycostatine) in the form of mouthrinses containing 1.4% sodium hydrogen carbonate. The stability of these solutions was tested at different temperatures (4-37 degrees C) with or without electric- or sunlight exposure and in two types of containers (glass and polypropylene) over a 15-day period. The admixtures were also monitored for colour change and pH. Amphotericin B and nystatin were quantified by high-performance liquid chromatography. At 4 degrees C, amphotericin B and nystatin were stable for 15 days in polypropylene. When stored in polypropylene at room temperature, with or without light protection, amphotericin B and nystatin were stable for 3 and 4 days, respectively.
