Role of nanostructured lipid carriers in the expression alterations of ATP-binding cassette transporter genes in fluconazole-resistant Candida glabrata. BIOIMPACTS : BI 2022; 12:561-566. [PMID: 36644547 PMCID: PMC9809133 DOI: 10.34172/bi.2022.23825] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 05/09/2021] [Revised: 12/14/2021] [Accepted: 02/13/2022] [Indexed: 11/05/2022]
Abstract
Introduction: This study was proposed to assess the potential role of efflux transporters in reversing fluconazole resistance in Candida glabrata isolates treated with fluconazole loaded nanostructured lipid carriers (FLZ-NLCs). Methods: The ultrasound technique was used to synthesize the FLZ-NLCs. Four fluconazole-resistant, as well as one susceptible standard C. glabrata isolates, were applied and exposed to FLZ/ FLZ-NLCs for 20 h at 37°C. Real-time PCRs were done to estimate the likely changes in ATP-binding cassette transporter genes. Results: Similar to the FLZ-exposed-susceptible standard strain which showed no alteration, the genes were not up-regulated significantly under the FLZ-NLCs treated condition. While they were over-expressed when the yeasts were treated with fluconazole. Conclusion: It is highly suggested that due to the nature of the NLCs which shields the whole conformation of the drug, FLZ is not recognized by the efflux transporter subunits and consequently the translocation would not happen.

Abstract
Terconazole (Tr) is the first marketed, most active triazole for vaginal candidiasis. Owing to poor skin permeation and challenging physicochemical properties, Tr was not employed for the treatment of cutaneous candidiasis. This is the first study to investigate the relevance of novel lecithin-integrated liquid crystalline nano-organogels (LCGs) to improve physicochemical characteristics of Tr in order to enable its dermal application in skin candidiasis. Ternary phase diagram was constructed using lecithin/capryol 90/water to identify the region of liquid crystalline organogel. The selected organogel possessed promising physicochemical characteristics based on particle size, rheological behavior, pH, loading efficiency, and in vitro antifungal activity. Microstructure of the selected organogel was confirmed by polarized light microscopy and transmission electron microscopy. Ex vivo and in vivo skin permeation studies revealed a significant 4.7- and 2.7-fold increase in the permeability of Tr-loaded LCG when compared to conventional hydrogel. Moreover, acute irritation study indicated safety and compatibility of liquid crystalline organogel to the skin. The in vivo antifungal activity confirmed the superiority of LCG over the conventional hydrogel for the eradication of Candida infection. Overall, lecithin-based liquid crystalline organogel confirmed its potential as an interesting dermal nanocarrier for skin targeting purpose.

Abstract
Terconazole is a new, broad-spectrum, triazole antifungal agent. The aim of this study was to compare the efficacy and safety of a 6-day course of a terconazole vaginal suppository (80 mg) with two doses of oral fluconazole (150 mg) for the treatment of severe vulvovaginal candidiasis (SVVC). In this prospective, randomized case-control study, 140 consecutive patients with SVVC were enrolled at the Department of Obstetrics and Gynecology of Peking University Shenzhen Hospital from July 1, 2013, through June 31, 2014. Patients with SVVC, initially at a 1:1 ratio, were randomly assigned to receive treatment with either the terconazole vaginal suppository or oral fluconazole. The patients had follow-up visits at 7-14 days and 30-35 days following the last dose of therapy. The clinical cure rates in the terconazole group and the fluconazole group were, respectively, 81.0% (47/58) and 75.8% (50/66) at follow-up day 7-14 and 60.3% (35/58) and 56.1% (37/66) at day 30-35. The mycological cure rates in the two groups were, respectively, 79.3% (46/58) and 71.2% (47/66) at follow-up day 7-14 and 62.1% (36/58) and 53.0% (35/66) at day 30-35 (P > .05 for all). Local irritation was the primary adverse event associated with terconazole, whereas systemic side effects were associated with fluconazole; however, these effects were minimal. This study demonstrated that a terconazole vaginal suppository (80 mg daily for 6 days) was as effective as two dose of oral fluconazole (150 mg) in the treatment of patients with SVVC; as such, terconazole could be a choice for therapy of this disorder.

Abstract
Vaginitis is a common gynecologic disorder that is responsible for 10 million office visits to physicians each year. Infectious vaginitis is the most common cause of a vaginal discharge, but other important diagnostic considerations include infectious cervicitis, a physiologic discharge, atrophic vaginitis, and allergic or irritant vaginitis. Although the history and gynecologic examination may suggest the diagnosis, laboratory confirmation should be routinely sought by performance of the vaginal pool wet mount examination, the amine whiff test, determination of the vaginal pH, and the Q-tip test. Once a precise diagnosis is made, effective therapy can then be prescribed. For patients with Candida vaginitis, therapeutic options include either the vaginal administration of a number of available imidazole or triazole antifungal agents or the prescription of the oral triazole agent fluconazole. Oral metronidazole remains the only effective treatment for trichomoniasis in the United States. Bacterial vaginosis, which has been linked to a number of obstetric and gynecologic complications, is effectively treated with oral metronidazole, although vaginal metronidazole gel and oral and vaginal clindamycin formulations are available as well.

Abstract
AIMS/BACKGROUND An A to G substitution at base pair 3243 in the mitochondrial tRNA(Leu(UUR)) gene (mt3243) is commonly associated with maternally inherited diabetes and deafness, and other diseases. It is possible that cell free mitochondrial DNA exists in serum and plasma from these patients, and these samples might be a source of material for the detection of such mutations. METHODS Sixteen patients with type 2 diabetes mellitus and 25 healthy subjects were tested for the 3243 mutation by polymerase chain reaction restriction fragment length polymorphism (PCR-RFLP) analysis. Plasma and serum from the 41 subjects were tested blind, without knowledge of the final diagnosis. RESULTS PCR amplification of the mtRNA(Leu(UUR)) region in mitochondrial DNA (mtDNA) in serum samples revealed the presence of mtDNA in all samples. After ApaI digestion of the amplified DNA fragments, mt3243 was detected in the serum and plasma samples of the seven patients with diabetes who had previously been found to have this mutation in their leucocyte DNA. None of the serum/plasma samples from the healthy subjects or those patients negative for mt3243 in their leucocytes had this mutation (p < 0.001). In addition, the degree of heteroplasmy of mt3243 appeared to be higher in serum and plasma samples than in leucocytes among mt3243 carriers (p < 0.05). CONCLUSIONS Therefore, mtDNA and associated mutations are present and detectable in serum and plasma. Plasma and serum might be alternative sources for the molecular diagnosis of mt3243 associated diabetes mellitus, as well as other mitochondrial mediated diseases.

Abstract
STATEMENT OF PROBLEM Soft lining materials continue to have a place in clinical removable prosthodontics. However, there is an increased probability of yeast colonization on soft lining materials. PURPOSE This study (1) assessed a method of evaluating the effect of long-term soft lining materials on the growth of yeast and (2) investigated the effect five soft lining materials had on the growth of three species of yeast. MATERIAL AND METHODS Coe Supersoft, Novus, and three experimental soft lining materials were investigated together with Candida albicans, Candida tropicalis, and Issatchenkia orientalis (formerly Candida krusei) yeasts. Strips of soft lining material incubated on blood agar plates were examined for inhibition of the growth of yeast. Soft lining materials soaked in sterile trypticase soya broth or water were inoculated with yeast and incubated. The change in colony forming units per milliliter from the initial load of yeast at 3 days was measured. Statistical analysis was performed with an independent paired Student t test. RESULTS Inhibition of yeast growth occurred for two soft lining materials. Despite the presence of sufficient viable organisms, differences between the initial load of yeast and the 3-day results were mostly small, both for the test and control groups, suggesting that the material does not support the growth of the tested yeast during this period. CONCLUSIONS The often described increased prevalence of yeast associated with soft lining materials in the oral environment is likely related to readily available nutrients in the mouth and the difficulty in maintaining and cleaning these materials.
